Sociodemographic influences on youth sport participation and physical activity among children living within concentrated Hispanic/Latino rural communities

Introduction Lack of physical activity (PA) among children living in rural communities is a documented public health problem. Although studies have examined community conditions defined by a rural–urban dichotomy, few have investigated rural community conditions with a concentration of Hispanic/Latino people. This cross-sectional study examined sociodemographic characteristics associated with youth sport (YS) participation and daily PA among children living within concentrated Hispanic/Latino rural U.S. Midwest communities. Methods During spring 2022, 97% of 3rd–6th grade children (n = 281, aged approximately 8–12 years) attending school in rural Midwestern communities (n = 2) with >50% concentration of Hispanic students participated in the Wellscapes Project, a community randomized trial. Participants completed the Youth Activity Profile and supplemental National Survey of Children’s Health questions assessing PA behaviors and YS participation. Caregivers of a subsample of children (n = 215; males, n = 93; females, n = 122) consented to pair their child’s survey results with school enrollment records (e.g., free/reduced lunch status and race and ethnicity). Mixed models with community as a random effect examined main and interaction effects of grade, sex, ethnoracial status, and family income on YS participation and these sociodemographic characteristics and YS participation on daily moderate-to-vigorous PA (MVPA). Results Approximately half of children participated in YS. Non-Hispanic White children (n = 82) were over five times more likely to participate in YS than Hispanic peers (n = 133) (OR = 5.54, 95% CI = 2.64–11.61, p < 0.001). YS participants accumulated 8.3 ± 2.3 more minutes of daily MVPA than non-participants (p < 0.001). Sixth graders, females, and Hispanic children reported lower daily MVPA than comparison groups (p < 0.05). Significant interaction effects on daily MVPA between grade and ethnoracial status (F(3, 204) = 3.04, p = 0.030) were also found. Discussion Disparities in sport participation and PA outcomes based on sociodemographic characteristics exist among children living in ethnoracially diverse rural communities. Strategies to promote YS participation, including community structural changes, may help reduce PA disparities. The research provides valuable insights for policymakers, public health professionals, and community members to address YS participation barriers, not limited to cost, while considering other PA-promotion efforts to improve child population health.

Introduction: Lack of physical activity (PA) among children living in rural communities is a documented public health problem.Although studies have examined community conditions defined by a rural-urban dichotomy, few have investigated rural community conditions with a concentration of Hispanic/Latino people.This cross-sectional study examined sociodemographic characteristics associated with youth sport (YS) participation and daily PA among children living within concentrated Hispanic/Latino rural U.S. Midwest communities.
Methods: During spring 2022, 97% of 3rd-6th grade children (n = 281, aged approximately 8-12 years) attending school in rural Midwestern communities (n = 2) with >50% concentration of Hispanic students participated in the Wellscapes Project, a community randomized trial.Participants completed the Youth Activity Profile and supplemental National Survey of Children's Health questions assessing PA behaviors and YS participation.Caregivers of a subsample of children (n = 215; males, n = 93; females, n = 122) consented to pair their child's survey results with school enrollment records (e.g., free/reduced lunch status and race and ethnicity).Mixed models with community as a random effect examined main and interaction effects of grade, sex, ethnoracial status, and family income on YS participation and these sociodemographic characteristics and YS participation on daily moderate-to-vigorous PA (MVPA).

Introduction
Although the benefits of physical activity (PA) are well-established (1,2), over 75% of children and adolescents, aged 6-17 years, living in the United States (U.S.) are failing to meet the current federal PA guidelines (3).As a consequence of this documented public health problem, the fifth iteration of the U.S. Department of Health and Human Services' Healthy People initiative includes 2030 national objectives targeting an approximate 7% increase in the total proportion of U.S. children and adolescents who participate in the recommended 60 min or more of moderate-to-vigorous PA (MVPA) every day, from 23.6 to 30.4% and 23.2 to 30.6%, respectively (4).
Communities are social systems of interaction that create the structural conditions that influence children's health behaviors, like PA (5,6).The structural conditions are labeled the social determinants of health, recognizing conditions in the environments where people live, learn, play, and age also affect PA and other health behaviors and outcomes (4).One way to categorize community conditions is by characterizing communities in a dichotomous or unidimensional fashion, such as the traditional rural-urban dichotomy (e.g., between places inside and outside metro areas) (7).But, studies using this approach to examine children's PA have produced divergent results, in which some studies have found that rural children are less active than urban children while others have found the opposite to be true (8)(9)(10)(11)(12).Scholars contend this classification may not adequately reflect the complexity within communities (7,13).Specifically, Sandercock et al. argue that the oversimplification of these spatially based concepts, explicitly for under-researched children living in rural communities with diversified contexts, setting environments, and cultural processes, may be one reason for diversity of PA outcomes, and they suggest that racial processes, among others, should not be discounted (14,15).
Another way to characterize community conditions is to define communities by concentration of ethnoracial diversity.But, studying ethnoracial diversity in isolation does not consider emerging social system processes resulting from the interaction between rural-urban and ethnoracial diversity (7,13).Although rural communities may be assumed to be homogeneous (e.g., fundamentally conservative, White, and economically dependent on farming), there is documented growing ethnoracial diversity in these communities over the past decade, marked by an influx of Hispanic immigrants into rural communities with service and manufacturing economic opportunities; thus, demanding a shift in the stereotypical rural rhetoric (16-18).Since the late 1970s, when family farms became fewer and larger with the rise of agribusiness, meat-processing plants began consolidating to areas where animals were raised, particularly in rural U.S. communities throughout the Midwest and Great Plains states (e.g., Nebraska, Iowa, and Kansas), to reduce costs (e.g., cheaper land and lower labor and transportation costs) (19).In response to labor shortages, many plants turned to immigrants, the majority of Hispanic origin, to fill this void, while relying on workers' networks for continual employee recruitment (20).Consequently, the growing diversity of this workforce, coupled with changes in industry, have impacted the sociodemographic and economic characteristics of Midwest rural communities and the settings (e.g., schools) nested within, such that many rural community profiles are characterized by poverty and bilingualism (21).These characteristics are often perceived to lead to adverse effects, explicitly in migrant boomtowns (i.e., increased crime rates, greater need for social services, and so-called native "white flight"); however, the literature does not confirm these perceptions (19,21).In sum, the sociodemographic characteristics of rural communities in the Great Plains suggest an oversimplified typology of communities where some rural communities are concentrated White, and some are concentrated Hispanic/Latino, often influenced by the community's industry and employment structures.
The focus here is to examine the PA of children who are members of understudied rural "migrant boomtown" communities with a concentration of Hispanic/Latino children.Barker's work on rural communities defined communities as systems of behavior settings, in which ecological units bounded by time and space drive patterns of behavior within a replicated social structure (22).Recently, this setting approach has been described as the community "wellness landscape" of settings that drives population PA outcomes (23).Rural behavior settings are places that provide a heterogeneous array of child adult-led services, such as afterschool programs, youth clubs, and sports (15,24).
One community setting frequented by children, comprised of games and practices, is the sport setting.The production of the community landscape of youth sport settings within the U.S. has long institutional history (25).As an institution, organized youth sport (YS) has evolved from low-cost, positive youth development practices teaching so-called "American" values of cooperation, self-control, and respect for authority, to, at times, highly competitive, performancebased operations within for-profit entities supporting a win-at-allcosts mentality (26,27).Despite this shift, YS, defined by the American Academy of Pediatrics as "PA that is directed by adult or youth leaders and involves rules and formal practice and competition" (28), continues to be a popular avenue to accumulate PA and other health benefits (29)(30)(31).Increasing sport participation among children and adolescents is also included as a Healthy People 2030 PA objective (4), although, the current YS system's pay-to-play model has erected barriers to participation, disproportionately impacting children from minority groups (32,33).For example, Kellstedt and colleagues found family income was a significant (p < 0.05) predictor of YS participation among predominantly White children (n = 235) living in rural communities, in which children with full-pay lunch status were almost four times more likely to participate than peers with free or reduced lunch (OR = 3.91, 95% CI = 1.95-7.8)(34).Additionally, the authors found YS participants accumulated significantly more daily average minutes of MVPA than non-participants (84.9 min vs. 78.1 min, p < 0.05), which is consistent with the literature (35)(36)(37).However, further investigation of the impact of race, ethnicity, and the combination of these characteristics (i.e., ethnoracial status) on YS participation and MVPA within increasingly diverse rural American communities has been recommended, as cost may not be the only barrier for entry (e.g., lack of programming, facilities, and transportation limitations) into these and other social systems of interaction (11,34).
It is well established that childhood PA is vital, valuable, and lacking, and the places where children live, learn, play, and age disproportionately impact this essential, modifiable health behavior.There is an opportunity to examine the influence of children getting more PA through YS participation (38); yet, there is a gap in understanding the sociodemographic characteristics related to YS participation in under-researched and under-resourced ethnoracially diverse rural communities and how these factors interact to influence PA outcomes (34,39).The goals of this study were to (1) examine the association between participation in adult-led organized YS opportunities by grade, sex, ethnoracial status, and family income, and (2) determine the influence of these factors (grade, sex, ethnoracial status, and family income) and organized YS participation on PA levels of children living in ethnoracially diverse rural communities.

Study design
This study was a cross-sectional sub-study of the Wellscapes Project.Wellscapes is a two-wave staggered-start community randomized trial (ClinicalTrials.govIdentifier: NCT03380143, 20/12/2017) and social epidemiology study of four rural U.S. Midwestern communities aimed at establishing a multilevel system infrastructure to increase youth population PA (40).The protocol for all study activities was approved by the Institutional Review Board at the University of Nebraska Medical Center (IRB #446-18-EP, IRB #439-18-EX).
In Wave 1 (fall 2018-spring 2020), two rural, predominantly non-Hispanic White communities were recruited.In Wave 2 (fall 2021-spring 2023), two rural communities with a majority of Hispanic children were targeted for recruitment based on community proximity to urban areas (i.e., distance greater than 10 miles from an urbanized area, classified as rural distant and rural remote) (41), school districts with a concentration (≥50%) of Hispanic children enrolled in 3rd through 6th grades (i.e., approximately 8 to 12 years of age) (42), and population size (i.e., less than 3,500 residents).Additional inclusion criteria for Wave 2 communities included the following: had one public high school, offered multiple adult-led group opportunities (e.g., youth club meetings, YS team practices, etc.) for children in 3rd through 6th grades, independent completion of a community health needs assessment with prioritization of obesity prevention in a community health improvement plan, and agreement by the local health department and public school district to participate in the study.

Study sample
The present study reports on spring 2022 population PA and corresponding contextual data collected during the Wellscapes Wave 2 baseline year (fall 2021-spring 2022).With permission from the school districts (n = 4; 2 public and 2 private), administration, and staff, all 3rd through 6th-grade public education classrooms (n = 16) and private education classrooms (n = 4) across the communities (n = 2) were eligible to participate in Wave 2's social epidemiology study.This consisted of the administration of an online PA surveillance instrument, available in English and Spanish, near the beginning and end of each school year during designated class time.The instrument is comprised of the validated Youth Activity Profile (YAP) (43), an online assessment explicitly designed for school-based evaluations of youth PA with 15 items that children and adolescents can complete in 15-20 min (44,45).Students in 4th grade and up can complete the YAP independently (46, 47); however, children as young as 3rd grade can complete the YAP with adult supervision as documented in the National Cancer Institute's Family Life, Activity, Sun, Health, and Eating (FLASHE) Study (48).The instrument also includes supplemental out-of-school organized activity participation questions from the National Survey of Children's Health 2017-2018 (NSCH) (49).We specifically concentrated on the second administration of the instrument in spring 2022 to capture children's PA behaviors that occurred during the school year and maintain consistency with work from Wave 1.Previous publications have documented the protocol (50) and summarized descriptive PA and YS participation patterns at the population level in the Wave 1 communities (34).
During spring 2022, 97% of 3rd through 6th-grade children across both communities (n = 281) participated in the social epidemiology study by completing the PA surveillance instrument.This study primarily focused on a subset of those children (n = 215) who had informed parental and guardian consent.This consent, distributed in English and Spanish, was obtained to pair children's school sociodemographic data (e.g., date of birth, sex, race, ethnicity, and free and reduced lunch status) with their respective PA data, including surveillance instrument responses, based on a Data Sharing Agreement (DSA) established with participating schools (50).

Study procedures
The research team trained school administrators and teachers to administer the online instrument as an in-class educational experience (e.g., to learn about PA and sedentary behaviors) and provided ongoing technical assistance.The instrument was shared via a secure, web-based application designed to support data capture for research studies hosted at the University of Nebraska Medical Center, REDCap (Research Electronic Data Capture) (51, 52).Coinciding with the conclusion of the Wave 2 baseline year, the instrument was administered during the end of April through early May 2022 (43,53).Children were guided through the online PA surveillance instrument with support from teachers and school staff and selfreported grade, sex, organized activity participation, and PA and sedentary behaviors.All 3rd through 6th-graders completed the YAP and supplemental questions within a classroom setting using the school's media resources.

Measures Sociodemographic characteristics
Individual sociodemographic characteristics in this study included grade, sex, ethnoracial status, and a proxy for family income (i.e., lunch status).When completing the YAP, children were asked to self-report grade (i.e., 3rd, 4th, 5th, or 6th grade) and sex (i.e., male, female, not listed, or prefer not to answer).The DSA permitted the school to provide additional sociodemographic information obtained from school enrollment records, including student name, identification number, date of birth, grade, sex, race, ethnicity, and family free and reduced-price lunch status (FRLS).The school shared these data on a secure platform with the research team, and members of the research team paired de-identified school enrollment data with YAP data for the subsample of children whose parents and guardians consented to the community trial (50).Variables of interest were based on enrollment data and included grade (i.e., 3rd, 4th, 5th, or 6th grade) and sex (i.e., male or female).
Ethnoracial status was created by combining school recorded ethnicity (i.e., non-Hispanic or Hispanic) and race (i.e., White, Black/African American, American Indian/Alaska Native, Asian, Multiple Races/Mixed, or Unknown/did not report).This variable was further dichotomized to include two groupings: (1) non-Hispanic White and (2) Hispanic and racially diverse (including all children identified as Hispanic regardless of race, and children identified as non-Hispanic and any race other than White), for data quality based on small sample sizes among race-related classifications (54).A family income variable was dichotomized based on FRLS.Consistent with our previous work, children with FRLS were considered "lower income, " and children with full pay lunch status were considered "higher income" (34,55).Within the constraints of the student enrollment records and DSA, we acknowledge lunch status is a sufficient proxy for family income based on the available data (56).

Youth sport participation
Participation in YS was determined using the supplemental NSCH questions added to the YAP (49).Specifically, these items assessed pastyear participation in out-of-school activities, including daily afterschool programs, sports teams or sports lessons, clubs or organizations, and other organized activities or lessons (e.g., music, dance, language, or other arts).The present analyses relied on child self-reported "yes" or "no" responses to the following question: "During the past 12 months, did you participate in a sports team or take sports lessons after school or on weekends?"(49).If a child answered "yes, " they were included as a YS participant.

Moderate-to-vigorous physical activity
The primary outcome variable of children's MVPA was estimated using published calibration equations developed specifically for the online version of the YAP (43).In the YAP, children respond to five questions about in-school PA and five questions related to out-of-school PA.The published algorithms were applied to the 10 PA items to create estimates of in-school PA, out-of-school PA, and weekend PA.The YAP items used to estimate weekday (Monday -Friday) in-school MVPA asked children to report how many days (0, 1, 2, 3, or 4 to 5 days) they walked or biked to school and how many days they walked or biked from school, how often they were running and moving as part of the planned games or activities during physical education, and how often they were playing sports, walking, running, or playing active games during recess (with response options including 0 = no physical education or recess, 1 = almost none of the time, 2 = a little bit, 3 = a moderate amount, 4 = a lot, or 5 = almost all of the time) (43).The YAP items used to estimate weekday out-of-school MVPA asked children to report how many days (0, 1, 2, 3, or 4 to 5 days) they did some form of PA for at least 10 min (1) before school (between 6:00-8:00 a.m.), (2) after school (3:00-6:00 p.m.), and (3) in the evening (6:00-10:00 p.m.), Monday -Friday (43).Weekend MVPA was estimated using the YAP items that asked about amounts of PA (no activity [0 min], small amount of activity [1 to 30 min], small-to-moderate amount of activity [31 to 60 min], moderateto-large amount of activity [1 to 2 h], and large amount of activity [more than 2 h]) accumulated on Saturday and Sunday (e.g., exercise, work/ chores, and family outings) (43).The average daily PA level was computed using a weighted average of weekday (both in-school and out-of-school) PA (5 days) and weekend PA (2 days).Past work with the YAP has shown that in-school and out-of-school PA values from the YAP were within 23 and 21% of values derived from an objective PA monitor, respectively, based on mean absolute percentage error calculations (43).

Data analyses
Descriptive statistics were used to summarize children's participation in YS for the primary social epidemiology study (n = 281) and the community trial sub-study (n = 215).Mixed-models were used to analyze the dichotomous outcome (i.e., 1 = Yes; 0 = No) of YS participation, and the continuous outcome of average minutes of daily MVPA.For all models, community was included as a random effect (34).SAS/STAT software, version 9.4 ( © 2002-2012) of the SAS System for Windows (Cary, NC), was used for all analyses.PROC GLIMMIX was performed to examine the dichotomous outcome of YS participation with the fixed effects of grade, sex, ethnoracial status, and family income.Interactions between the effects of grade, sex, ethnoracial status, and family income on YS participation were also explored.PROC MIXED was used to examine average minutes of daily MVPA with the fixed effects of grade, sex, ethnoracial status, family income, and YS participation.Similarly, interaction effects of grade, sex, ethnoracial status, family income, and YS participation on average time in MVPA were examined.Backward elimination of non-significant interactions based on statistical significance of p < 0.05 was used where non-significant higher order interactions were eliminated first, and then the models were refit (57,58).

Results
Descriptive characteristics of children in the Wellscapes social epidemiology study and those who participated in the Wellscapes community trial are found in Table 1.A total of 281 3rd through 6th-grade children (97% of total student population) completed the YAP and supplemental NSCH questions, and of those, 215 children had parental and guardian consent to be included in the community trial.Among the community trial participants, more children identified as Hispanic and racially diverse than non-Hispanic White, had lower family income than higher family income, and participated in YS opportunities than did not.

Youth sport participation
Figure 1 highlights the proportion of children in the community trial reporting YS participation based on sociodemographic characteristics, and Table 2 shows the results from the mixed-model regression predicting YS participation among trial participants.Non-Hispanic White children were over five times more likely to participate in YS than Hispanic and racially diverse peers (OR = 5.54, 95% CI = 2.64-11.61,p < 0.001).Additionally, children with higher family income were almost twice as likely to participate in YS than children with lower family income (OR = 1.94, 95% CI = 0.98-3.86),however, this finding was not significant (p = 0.058).There were also no significant differences in the likelihood of participating in YS by grade level or sex, and significant interactions were not found.

Moderate-to-vigorous physical activity
Table 3 presents least squares means and significant differences in daily MVPA by fixed effects of grade, sex, ethnoracial status, family income, and YS participation.There were significant main effects on daily MVPA for grade (F(3, 203) = 24.03,p < 0.001), sex (F(1, 203) = 195.46,p < 0.001), ethnoracial status (F(1, 204) = 6.23, p = 0.013), and YS participation (F(1, 201) = 13.47,p < 0.001).Compared with 3rd, 4th, and 5th graders, 6th graders reported significantly less time in daily MVPA.Additionally, males reported significantly more daily minutes of MVPA (mean = 86.6 ± 3.1 min/ day) compared with females (mean = 60.0 ± 3.0 min/day).Children identified as non-Hispanic White also reported significantly more minutes of daily MVPA than peers identified as Hispanic and racially diverse (mean = 76.2 ± 3.2 min/day and 70.4 ± 3.0 min/day, respectively).Significant interaction effects on daily MVPA between grade and ethnoracial status (F(3, 204) = 3.04, p = 0.030) were also found, as highlighted in Table 4. Fourth and 6th graders identified as non-Hispanic White reported significantly more minutes of daily MVPA than their respective grade-level matched Hispanic and racially diverse peers, with an approximate mean difference of 9.8 min and 12.3 min, respectively.Conversely, 5th graders identified as Hispanic and racially diverse reported significantly more minutes of daily MVPA (mean = 75.1 ± 3.9 min/day) than 6th graders identified as non-Hispanic White (mean = 66.0 ± 4.2 min/day).In addition, Hispanic and racially diverse 3rd graders reported more minutes of daily MVPA compared with non-Hispanic White 3rd graders (mean = 83.0 ± 3.6 min/day and 80.4 ± 4.2 min/day, respectively), although the difference was not significant.There were no significant main effects on daily MVPA by family income (F(1, 204) = 0.13, p = 0.723).Children participating in YS opportunities reported significantly more average total minutes of daily MVPA (mean = 77.4± 3.0 min/day) than those not participating (mean = 69.1 ± 3.2 min/day).Figure 2 shows differences between YS participation and average minutes of MVPA, including differences in total daily minutes of MVPA per weekday and weekend days (Monday-Sunday), and differences in minutes of MVPA during in-school and out-of-school time per weekday (Monday-Friday).Children who participated in YS opportunities had similar in-school MVPA than children who did not participate in YS (23.7 min and 21.9 min, respectively, p = 0.061).However, YS participants reported significantly (p = 0.006) more daily minutes of out-of-school MVPA per weekday (mean = 51.4 ± 1.2 min/day) than those who did not participate (mean = 45.6 ± 1.7 min/day).

Discussion
The current study examined the association of grade, sex, ethnoracial status, and family income on YS participation and their impact on the average daily MVPA of children living in ethnoracially diverse rural communities.In this study, YS participation included involvement in a sports team or sports lessons after school or on weekends.A key finding was that approximately 54% of children reported participating in organized YS opportunities within the past 12 months.Although this percentage is consistent with nationally representative data for children and adolescents aged 6-17 years from 2020 (59), which the authors asserted may not be reflective of changes in participation based on the COVID-19 pandemic, it is lower than the 80% of rural children engaged in YS as reported by Kellstedt et al. (34) based on data collected in spring of 2019 (34).This difference may be a difference among communities or, as the literature suggests, YS participation may still be rebounding to  pre-pandemic levels, while recognizing significant participation disparities based on sociodemographic characteristics (e.g., sex and race) existed during the pandemic (60,61).For example, Fleming et al. ( 61) found that ethnoracially diverse (i.e., Asian, Latinx, and Multiracial) and rural children spent significantly less time in YS settings during the pandemic than comparative peers (i.e., White and urban children, respectively), and as a result, may be experiencing a "double jeopardy" effect in returning to organized sport opportunities given participation disparities that existed prior to the pandemic (61).Similarly, organized YS opportunities themselves have also been impacted by the COVID-19 pandemic (62,63), and in rural communities, where the availability and access to organized YS have been shown to be more limited pre-pandemic (11,64), previously existing opportunities may have struggled to survive; in turn, widening participation gaps for already vulnerable populations.Despite these gaps and the need for more empirical research examining the impact of community disruptions (e.g., COVID-19) on organized YS systems, many (>50%) children post-system disruption in this study reported YS participation.Thus, rural community improvement of the local YS system has the potential to impact population health outcomes, including childhood PA, provided the proportion of children accessing YS opportunities (34,35).
Characterizing children by grade level and sex revealed no significant differences in organized YS participation, which is consistent with 2020 findings reported in a recent National Center for Health Statistics' Data Brief (59).Specifically, Black and colleagues found that while the percentage of children (aged 6-17 years) that participated in sports was higher for males compared with females (56.1 and 52.0%, respectively) and for children aged 12-17 years compared with children aged 6-11 years (55.6 and 52.5%, respectively), the observed differences were not significant (59).Similarly, in this study, males and 6th graders (typically aged 11-12 years) from the community trial had higher rates of YS participation (57.0 and 60.0%, respectively) than females (52.5%) and 3rd (55.2%), 4th (50.0%), and 5th (52.0%) graders, collectively, but the results were non-significant.These findings have also been observed in other studies (65), including those exploring midwestern rural areas (34, 66), which may be highlighting dramatic shifts in rural community cultural expectations for and acceptance of female YS participation (e.g., reversing sex and gender-based inequalities in organized sport structures), or, more practically, the need to solve local issues of supply and demand regardless of a child's age or sex, or any embedded structural inequities (e.g., need to fill team rosters with limited supply of participants) (67)(68)(69).Future research should continue monitoring YS participation patterns based on grade and sex, while being mindful to explore organized YS participation patterns in children beyond 6th grade, where middle-and high-school sanctioned sports impact the community wellness landscape and sport dropout percentages often increase (70).Additionally, calls to include the examination of gender and sexual identity and sport warrant further investigation, particularly with the rise in gender and sexual fluidity among children and adolescents (71,72).Advocates recommend policymakers develop more inclusive, evidence-based sport policies (e.g., Canadian Centre for Ethics in Sport), to create safe sport environments for all athletes, regardless of identity (72).Although, we acknowledge the difficulty of this responsibility in light of current laws restricting gender-affirming care and recent bans on transgender sport participation (73).
Our work also revealed that rural children classified by family income were not significantly different in organized YS participation, but ethnoracial status was significantly associated with participation.Specifically, children identified as non-Hispanic White were over five times more likely to participate in YS than Hispanic and racially diverse peers (OR = 5.54, 95% CI = 2.64-11.61,p < 0.001).This finding is noteworthy since much of the literature supports disparities in YS participation based on family socioeconomic status (33,34,65,74), whereas studies primarily comparing ethnic backgrounds (e.g., Hispanic and non-Hispanic) of children with YS participation are scarce.Racial and ethnic sport disparities have been documented among secondary school children (i.e., grades 8th, 10th, and 12th) (65) and children aged 6-17 years (59) living in the U.S., as well as among children living in other countries (75)(76)(77).A cross-sectional study by Wijtzes et al. (75), examining social inequalities in young children's (n = 4,726; average age of 6 years) sports participation and outdoor play in the Netherlands, found that all ethnic minority children (i.e., Surinamese-Creole, Surinamese-Hindustani, Dutch Antillean, Cape Verdean, Turkish, and Moroccan) were more likely to not participate in sports compared with native ethnic majority Dutch children, with the highest odds for Turkish children (OR = 3.16, 95% CI = 2.51-3.98,p < 0.05).However, when adjusting for family social economic position, many ethnic-related associations became non-significant (75).This attenuation, despite glaring differences in study characteristics, may have occurred in the present study if a more comprehensive indicator of social economic status was used in place of FRLS, but we must not downplay the clear association found between ethnoracial status and YS participation.We must also continue studying the social and structural factors underlying this inequality (e.g., cultural norms, discriminatory processes, and acculturation characteristics) (77), especially in rural communities with growing diversity, to understand if the differences in YS participation based on ethnoracial status stem from broader inequities (e.g., lack of culturally-relevant sport opportunities, parental time opportunities, unnecessary documentation for registration, and inadequate communication translations), possibly leading to "unfair and avoidable differences" in health outcomes (69).Thus, examining the root causes of sport and PA-related inequities is vital to advance health equity, including support for more equitable organized YS opportunities where all children are encouraged to participate.
There are many benefits associated with persistent YS participation (78,79), and although this study did not examine the breadth nor continuation of children's organized sport participation in subsequent years, it did confirm YS plays a significant role in accumulating daily PA.Namely, we found that YS participants had significantly (p < 0.01) greater MVPA than non-participants, by approximately 8 min more per day and 6 min more per weekday out-of-school time (mean diff = 8.3 ± 2.3 min/day; mean diff = 5.8 ± 2.1 min/day, respectively), which are not small amounts when accumulated over the span of a week.Yet, differences in in-school MVPA between YS participants and non-participants were non-significant (mean diff = 1.8 ± 0.9 min/day), suggesting organized YS opportunities provide a meaningful contribution to PA, particularly for rural children outside of the school day.These findings are supported in the literature (34,35,80), but warrant further investigation, as type and level of sport opportunities (e.g., recreational and competitive soccer, volleyball, and basketball), context and location of practice sessions (e.g., outdoor full-field scrimmage or indoor walkthrough the day before a game), and leader-level characteristics and routines (e.g., volunteer or paid coaches, following predefined practice sessions developed by organizational authority or having flexibility to change sessions based on participant feedback), are highly variable, especially in under-resourced rural communities, and influence the amount of time children spend being active (81, 82).Thus, future research needs to assess the explicit and implicit rules of specific sport organizing bodies, among other factors, to determine how different sport practices may be promoting or discouraging associated outcomes like PA.
Another key finding in our study confirmed what is already known about the patterns of childhood PA characterized by grade and sex (83-86).Specifically, we found significant differences in daily MVPA by grade and sex.Compared with 3rd, 4th, and 5th graders, 6th graders reported the lowest average daily minutes of MVPA, with the largest mean difference between 3rd and 6th graders (i.e., approximately 22 min/day).In addition, males reported higher amounts of daily MVPA than females (mean diff = 26.6 ± 1.9 min/day).Lower levels of MVPA as children age and lower levels of female MVPA have been presented in other studies, but reasons for these differences have been mixed (87, 88).Sport participation has been cited as a factor contributing to PA disparities (89), but our study does not show a significant decline in YS participation by grade nor a significant difference between male and female participation rates.Therefore, similar to the results shared by Kellstedt et al. (34), YS does not appear to be a driver of PA differences among rural children with these sociodemographic characteristics and begs a broader examination of other environments children frequent (e.g., home, school, youth clubs, etc.) to uncover why consistent PA disparities by grade and sex exist.Within the community wellness landscape of settings, the structure of the school day, for instance, may be driving the grade-related drop in PA, as older children's access to recess and physical education classes are often limited or nonexistent compared to opportunities for younger children (65,90).Thus, educators (e.g., school administrators and teachers) can play a critical role in improving child population health by finding ways to insert time devoted to PA (i.e., PA sessions) during the school day.Additionally, Stoepker and Dzewaltowski (91), although interested in out-of-school time leaders, provide elements of a novel data coaching intervention that may assist teachers in this PA-promotion practice.As a result, investigating the ecological processes and patterns that influence PA behaviors in non-sport rural settings is fundamental to reducing PA-related health disparities.
Organized YS, however, may be a driver of the significant difference in daily MVPA observed by ethnoracial status (p = 0.013).We acknowledge the approximate 6-min difference found between non-Hispanic White and Hispanic and racially diverse children should be interpreted with caution provided the reliance on selfreported PA.However, our results are consistent with earlier evidence for racial and ethnic PA disparities (59,86,92), even if estimates suggest children are meeting the daily PA guidelines.A 2021 mixed methods study exploring PA patterns and parental influences on rural Latino school-aged children (n = 27 3rd-5th graders) also found 100% of children met PA guidelines as measured by accelerometry (93), but parents (n = 31) were quick to acknowledge PA barriers and challenges for children.Specifically, the authors highlighted homework, technology (e.g., computer games and television), and a lack of engagement in organized team and league sports after school as major barriers to being active.Aside from children not being interested in playing sports, parents recognized cost and transportation as additional YS barriers but also shared their children engaged in more unstructured activity outside during afterschool hours (93).As a result, future whole-of-community interventions (6) aimed at increasing daily PA for ethnoracially diverse children living in rural communities may need to both advocate for low-cost and easily accessible PA opportunities, like YS programs, and also encourage more unstructured free play engaging the entire family.Unlike grade, sex, and ethnoracial status, family income did not significantly impact children's average daily MVPA.It is often assumed children living in poverty are more likely to be less active than children from higher-income families, but evidence does not consistently reflect this pattern (83,94).This inconsistency has also been noted for children living in rural communities (34,95).Like rural children identified as Hispanic and racially diverse, children from low-income families may be more active while outdoors in unstructured free play, thus, offsetting the PA accumulated in more structured activities among higher-income peers (95, 96).Additionally, in this study, family income did not have a significant effect on YS participation, so sport opportunities may be more accessible regardless of cost, or other factors, such as issues of supply and demand and a desire for community belonging, may encourage YS participation despite cost (67,97).However, more research is warranted since family income can rapidly change, thus, confirming the need for a more comprehensive indicator of social economic status, like social class (98,99), to determine if PA disparities exist.This is particularly relevant in rural communities with growing ethnoracial diversity where members of certain classes often have more power and control over others based on factors like wealth, education, and occupation.
We also observed significant interactions between grade and ethnoracial status for the primary outcome of children's average minutes per day of MVPA.In most cases, children identified as non-Hispanic White reported more minutes of daily MVPA than Hispanic and racially diverse peers; however, differences were only significant for the 4th and 6th grade comparison groups.Conversely, Hispanic and racially diverse 3rd graders reported more minutes of daily MVPA compared with non-Hispanic White 3rd graders, although the difference was not significant.A study by Barr-Anderson et al. (100) supports a race/ethnicity by time interaction; however, the authors found no significant PA differences between Hispanic youth and White and Black youth at 5th, 6th, and 7th grade timepoints but acknowledge the sample size for Hispanic youth (n = 72) was significantly smaller than the other racial subgroups (Black, n = 275; White, n = 296).Despite this limitation, the study also reported ethnoracial differences in the factors that influenced total PA and age-related changes in PA.For example, among Hispanic youth, parent report of seeing other children outdoors was positively associated with total PA, while parent-reported child sport participation was one factor positively associated with total PA among White children (100).This, according to Hasson (101), "sheds light on the complexity of physical activity behavior and demonstrates that one size does not fit all when attempting to address physical inactivity in a racially and ethnically diverse group of children and adolescents." We would add these factors might also help to shine light on why non-Hispanic White children were over five times more likely to participate in YS than Hispanic and racially diverse peers, but additional exploration is necessary given the gaps in the literature (100).

Limitations
Provided the diversity of organized YS opportunities within local communities and across the U.S. and the fact our sample was limited to two rural Great Plains communities and their respective YS systems, the results of this study should be interpreted in light of its limitations.The children in the communities from this wave of the Wellscapes Project were primarily Hispanic and racially diverse and may not be representative of all rural American communities.However, results from the first wave are available and represent sociodemographic variability from Wave 2 (i.e., predominantly White rural communities) (34).Additionally, we did not account for cultural heterogeneity among Hispanic and racially diverse children and acknowledge the need to examine one's country of origin, the amount of time in the U.S., and preferred language, explicitly as limiting materials (i.e., PA surveillance instrument and consent forms) to English and Spanish may have resulted in sampling and response biases (102).Next, there are limitations to the self-report measure of organized YS involvement and PA used in the present study.The YAP is designed to provide reasonably accurate group-level estimates of daily MVPA, but the conclusions are still based on youth self-reported data.An improved self-report instrument might also be more sensitive to the different types and number of sports played among YS participants, which may influence children's PA and other quality of life factors (103).Future research should consider adopting a protocol similar to that defined by Essay and colleagues (23) to gain more objective data about children's PA and participation in adult-led organized opportunities not limited to YS, as we have previously alluded to the importance of understanding the quality and quantity of organized opportunities and the PA opportunities nested within.However, obtaining an objective PA outcome measure (e.g., accelerometry) may result in a sample not fully representative of the community; plus, data collection efforts are resource intense (23).
Furthermore, we must acknowledge the limitation of the crosssectional study design, in which a causal link between YS participation and PA cannot be established.Future experimental study designs should also consider rural children's participation in non-sport out-ofschool time organized activities, like afterschool programs, as well as time spent in unstructured activities (e.g., free play) to capture the larger community wellness landscape, and overall PA implications.In addition, our study's definition of family income based on lunch status also warrants attention, as a more comprehensive indicator, like social economic status, may be more accurate (100).However, this classification is considered a sufficient proxy given the privacy requirements associated with school student enrollment records (56).

Conclusion
Youth physical activity (PA) has declined over time, and opportunities for activity vary by where children live, learn, and play.Lack of PA among children living in rural communities is a documented public health problem, although much of the literature is constrained by the classic rural-urban dichotomy, failing to account for the complexity within communities.One such complexity is ethnoracial diversity, characteristic of Midwest migrant boomtowns.Another complexity is the heterogenous landscape of opportunities within communities, including organized sport settings.As a result, this study embraced this complexity and attempted to fill several significant gaps by examining sociodemographic factors related to youth sport (YS) participation and how these factors interact to influence PA among children living in ethnoracially diverse rural communities.This study suggests that participating in organized YS plays a critical role in the daily MVPA of children living in ethnoracially diverse rural communities.However, disparities in YS participation and PA outcomes, primarily attributed to ethnoracial status rather than family income, assert the need for further investigation to determine who and what might be driving these phenomena.Additionally, our findings suggest the need to advocate for the removal of other, non-cost related YS participation barriers, such as policies and practices provoking exclusion (e.g., entry rules and gender stereotypes).Time spent in unstructured activities also warrants more research, as future findings may suggest these low-to-no cost opportunities may be more advantageous when considering population health outcomes across the lifespan.Furthermore, understanding the relationships between grade, sex, ethnoracial status, and family income on organized YS participation can also inform whole-of-community interventions targeting PA policy, systems, and environmental change strategies to help create more equitable and accessible behavior settings for children living in concentrated Hispanic rural communities.Ultimately, increasing YS participation, consistent with Healthy People 2030 objectives, could make a significant impact on the PA and health of children living in ethnoracially diverse rural communities.
