Abstract
Aims:
Influenza infection is a health burden in children, and the influenza vaccine is an important prevention strategy for flu illness. Parents play a crucial role in children’s influenza vaccination. The study aimed to assess parental knowledge, attitudes, and practices (KAP) related to influenza illness for their children and explore factors that may impact their decisions.
Methods:
This cross-sectional study was conducted in a tertiary hospital in Guangzhou from November 2022 to April 2023. Answers to KAP questions regarding influenza illness and vaccination were summed, with a total KAP score of 20. Univariate and multivariate logistic regression models and linear regression models were conducted to explore the factors associated with influenza vaccination. The results were presented as odds ratios (ORs), β, and 95% confidence intervals (CIs).
Results:
Overall, 530 parents were respondents, of whom 162 (30.56%) had vaccinated their children during the past year. The mean KAP score (standard deviation) was 13.40 (3.57). Compared to parents who reported non-vaccinated for their children in the past year, the parents who reported an influenza vaccination have higher knowledge scores, attitude scores, practice scores, and total scores. Child body mass index, parental education level (under college), parental work (part-time), and more than two family members over 60 years old were negatively correlated with knowledge score. Child health condition and knowledge score were positively correlated with attitude score. Parental age was negatively associated with attitude score.
Conclusion:
Though high awareness about influenza illness and vaccination for parents, the coverage rate of influenza vaccination in children was lower in Guangzhou. Implementing public health policies is necessary to spread knowledge about influenza illness and vaccination and to promote the practice of receiving the influenza vaccine in children. Education campaigns would help change the attitudes of parents toward vaccinating their children against the flu.
Introduction
Influenza is a common and serious infection marked by fever, cough, sore throat, chills, muscle ache, and general malaise (, ). It affects both adults and children, with children having a higher seasonal prevalence (20–30%) (). Annually, influenza leads to up to 35,000 influenza-virus acute lower respiratory tract infection-associated deaths in children under 5 worldwide, posing a significant societal burden ().
Annual influenza vaccination is the most effective preventive measure against the flu, especially in children, significantly reducing infection risk, severe complications, hospitalizations, and deaths (, ). Many countries, such as China, prioritize vaccinating children aged 6 months to 18 years (). However, in China, vaccination coverage for children is low, approximately 11.9%, compared to higher rates in developed nations such as Europe and the United States ().
Parents play a crucial role in deciding whether their children get vaccinated against influenza. Their understanding and attitudes toward vaccination are key influencers (, ). Misconceptions about vaccine safety and effectiveness, concerns about side effects, and insufficient awareness about vaccination’s importance contribute to parental vaccine hesitancy (, ). Additionally, cultural beliefs, socioeconomic status, healthcare access, and information sources shape parental vaccination decisions (). This study aimed to explore the knowledge, attitudes, and practices (KAP) of parents regarding the influenza vaccine for their children and explore factors that may impact their decisions.
Methods
Study design, setting, and participants
From November 2022 to April 2023, parental caregivers of children aged 6 months to 18 years, who were treated at the department of infection disease of a tertiary hospital in Guangzhou, were selected as participants for this cross-sectional study. Exclusion criteria included (1) children aged <6 months or > 18 years old (2) missing information on influenza vaccination within the past year (3) individuals with allergies to the influenza vaccine or contraindication, and (4) individuals who were unable to complete the questionnaire due to writing or hearing disability.
At the department of infection disease in a selected tertiary hospital in Guangzhou, the investigator conducted face-to-face questionnaire surveys with parents in the waiting and observation rooms. All investigators were qualified and trained medical professionals, including physicians and nurses, who were required to work conscientiously. Sample size calculation was performed using the PASS 11.0 version, yielding an optimal size of 554, considering a 5% margin of error, a 95% confidence level, and a conservative estimate of vaccination coverage at 11.9% (). Taking into account a shedding rate of 10%, a total sample size of 675 was needed for this survey. Finally, 619 parents participated in the study.
Measurement tools
The survey included demographic information and influenza history for both children and parents. For children, socio-demographic details encompassed gender, age, height, weight, race, education level, health condition, and health insurance. Influenza history covered the children’s influenza history, that of their friends, their COVID-19 history, allergies to influenza vaccination, and contraindications for influenza vaccination. For parents, socio-demographic data included parental role, age, residence, marital status, education level, income, work, health condition, health insurance, and the presence of more than two family members over 60 years old in their household. Parents reported their influenza vaccination status. Influenza cases were diagnosed based on criteria established by the National Health Commission of the People’s Republic of China ().
After reviewing relevant literature, a KAP questionnaire was developed and adapted to the local culture and context in Chinese (, ). The KAP questionnaire consists of 20 items derived from the literature review, with 7 items for Knowledge, 9 items for Attitude, and 4 items for Practice. Each correct response in the Knowledge section was assigned one point, while incorrect or “I do not know” responses received zero points. Participants were categorized based on their knowledge scores into poor knowledge (0–2), moderate knowledge (), and high knowledge () groups. Attitude scores were based on varying response scales, including a 7-point disagree to agree scale, with one point awarded for each “Yes” response and zero points for “No” or “I do not know” answers. The Practice section included four statements related to influenza vaccination practices. Scores for the total questionnaire and each section ranged from 0 to 20, such as 0 to 7 for Knowledge, 0 to 9 for Attitude, and 0 to 4 for Practice. The Cronbach’s α coefficient for the KAP questionnaire was 0.71.
Ethical consideration
The study was reviewed and approved by the Ethics Committees of Guangzhou Women and Children’s Medical Center, Guangzhou Medical University [No. 2022-257A01]. Written consent was obtained from all parents before filling out the questionnaires.
Statistical analysis
Categorical variables were described using numbers and percentages, and a comparison between the two groups was made using the chi-square tests and Fisher exact tests. The normality of quantitative data was tested using skewness and kurtosis, and the equality of variances was tested using Levene’s tests. Continuous variables were presented as means and standard deviation. Statistical differences between the two groups were detected utilizing Student’s t-test and Satterthwaite’s t-test for homogeneity and heterogeneity quantitative data. Potential covariates were identified using univariate logistic regression models and univariate linear regression analysis. Subsequently, univariate and multivariate logistic regression models and linear regression models were conducted to explore the factors associated with influenza vaccination in children’s parents. The results were reported as odds ratios (ORs), β, and 95% confidence intervals (CIs). All statistical analyses were performed using R version 4.3.1 (2023–06–16 ucrt). A two-tailed p-value of <0.50 was considered statistically significant.
Results
Characteristics of parents and children
Out of 619 questionnaires distributed, 89 were excluded due to missing information on influenza vaccination within the past year (n = 69), and allergies or contraindications to the influenza vaccine (n = 20). The characteristics of children and parents are shown in Tables 1, 2, respectively. Among the 530 respondents, 368 (69.43%) did not administer influenza vaccination to their children. The mean age of vaccinated children was 4.77 (3.49) years old. Out of the 530 included parents, 426 (80.38%) were mothers. The average age of parents was 34.06 (5.31) years old. Parents possessing a college education level accounted for 283 (53.4%). Concerning those without influenza vaccination, children with influenza vaccination were younger on average, and so smaller, with lower weight, with lower education level, and with younger parents on average (all p < 0.05).

Knowledge, attitudes, and practices of parents regarding the influenza vaccine for their children
Table 3 shows the KAP scores for responses to influenza vaccination. The mean KAP score was 13.40 (3.57). The scores for knowledge, attitudes, and practices were 5.77 (1.29), 7.26 (2.10), and 1.68 (1.69), respectively. Compared to parents who reported without vaccinating their children against influenza in the past year, parents who reported an influenza vaccination have higher scores for knowledge, attitudes, practices, and total score (all p < 0.001). The distributions of scores for KAP are presented in Figure 1. Interestingly, despite reported high knowledge and attitude scores, the practice score remained low. Furthermore, 238 (44.9%) respondents have a practice score of 0.

Frequency of response for each question on vaccine hesitancy reported by parents.
In total, 162 (30.56%) respondents reported vaccinating their children against influenza in the past year. The data distribution on four items in practices is presented in Figure 2. Among the respondents, 106 (27.9%) vaccinated their children against influenza occasionally, 134 (25.3%) vaccinated their children every year, and 215 (40.6%) never had their children vaccinated. Parents who got their children vaccinated against influenza were mainly driven by their decisions. Parents who did not administer the influenza vaccine to their children stated lack of recommendation by health providers as the most common reason (28.80%).

Factors associated with children receiving influenza vaccination
In Supplementary Table S1, a high attitude score was associated with higher odds of children receiving the influenza vaccine (OR = 1.17, 95%CI: 1.05 to 1.31). Knowledge score was marginal significance with odds of children receiving the influenza vaccine (OR = 1.19, 95%CI: 1.00 to 1.43). Child body mass index (BMI) (β = −0.02, 95%CI: −0.04 to −0.01), parental education level (under college) (β = −1.34, 95%CI: −1.98 to −0.71), parental with part-time work (β = −0.29, 95%CI: −0.51 to −0.07), and more than two family members over 60 years old (β = −0.28, 95%CI: −0.49 to −0.07) were negatively correlated with knowledge score. Child health condition (β = 0.28, 95%CI: 0.10 to 0.47) and knowledge score (β = 0.26, 95%CI: 0.20 to 0.33) have a positive correlation with attitude score. Parental age (β = −0.02, 95%CI: −0.04 to −0.01) was negatively associated with attitude score, indicating that the younger the parents, the higher the score in vaccine attitudes. Influencing factors on knowledge score and attitude score are presented in Tables 7, 8, respectively.

Discussion
Our study found most parents had a high knowledge level and positive attitudes toward influenza vaccination, while only 30.56% of parents reported vaccinating their children against influenza in the past year. The results indicated a gap between parents’ intention and their actual vaccination behaviors in the realm of healthcare practices. The primary reason cited for not vaccinating was the absence of a recommendation.
Parental knowledge significantly influences the intentions regarding children’s flu vaccination, as supported by Zhao et al. (). A survey conducted in the Nanhai district of China showed a positive association between heightened levels of influenza knowledge and previous influenza information with a willingness to vaccinate ().
Our study found that children’s BMI, parental education level, parental with part-time work, and having more than two family members over 60 years old were negatively related to knowledge score. Individuals with higher BMI often face social stigma and discrimination, potentially resulting in diminished health literacy and participation in preventative health practices (). Therefore, these parents might have limited vaccination knowledge, leading to lower knowledge scores. Parental education level has been linked to decreased knowledge regarding vaccinations (). Parents with lower education levels may have limited access to credible health information sources, impeding their ability to obtain accurate knowledge on influenza vaccination for their children. Moreover, parental part-time work and having two or more people over 60 years old in the household may contribute to lower knowledge scores due to time constraints and competing responsibilities. The presence of older adult family members may divert parents’ focus and time away from seeking vaccination information. Given the limited knowledge about influenza vaccination among Chinese parents, it is crucial for the China Centers for Disease Control and Prevention to offer comprehensive and accessible information to address this gap.
The majority of parents had favorable opinions toward the influenza vaccine. Parents showed high willingness (70.94%) to vaccinate their children against influenza in our study, indicating that China has done quite well in the publicity and implementation of the law on the prevention and control of infectious diseases (). Moreover, our study found positive correlations of knowledge score, the health status of children with attitude score. Parental knowledge plays a crucial role in vaccination decision-making (). Parents who possess accurate knowledge are more inclined to comprehend the advantages of influenza vaccination and make well-informed decisions for their children (). Parents with children in good health may have had positive experiences with previous vaccinations, which influence their perspectives and beliefs regarding the effectiveness and significance of vaccines (). A negative relationship was reported between parental age and knowledge score, as supported by Alenazi (). Younger parents demonstrated higher scores in attitude categories due to their increased internet exposure, which facilitated access to online influenza-related information. Moreover, our findings indicated that as knowledge improved, attitudes became increasingly optimistic ().
Only 30.56% of parents reported influenza vaccination for their children in the past year, which is lower compared to rates in various nations such as the U.S. (), United Kingdom (), Italy (), and Saudi Arabia (). The recommendations provided by physicians were crucial in promoting influenza vaccination among children (, ). A survey conducted in the U.S. showed that healthcare provider recommendations significantly influenced the uptake of influenza vaccine in children aged 9–13 years (). Consequently, stakeholders should educate healthcare professionals about the guidelines for influenza immunization and enhance their knowledge on the subject. The commonly cited reason (28.80%) for parents not taking their children for influenza vaccination was the absence of recommendations, indicating the necessity to promote influenza vaccination. Media can be utilized more effectively to spread information about influenza illness and vaccination as it is an effective tool in increasing vaccination rates in children (). Additionally, parents’ apprehension regarding potential side effects of the vaccine presented a barrier to childhood influenza vaccination, with various studies identifying concerns about vaccine safety as the primary reason for refusing vaccination (, ).
The status of influenza vaccination in children is suboptimal, indicating that healthcare providers should focus on improving the situation. Strategies should not only involve providing information but also address parent’s attitudes and concerns. Targeted intervention measures should be implemented based on influencing factors and individual characteristics of health education. Moreover, healthcare providers, serving as a vital and trustworthy source of vaccine-related information for the public, could benefit from additional training in professional ethics and specialized knowledge to enhance parental awareness (, ).
Several limitations should be recognized in the study. First, the study used a cross-sectional design with respondents sampled solely from one hospital. Future studies should encompass larger and multi-center samples. Second, health conditions for parents and children were obtained by self-reported, leading to response bias. Finally, the majority of parents were women (80.38%), raising concerns about gender bias. The extent to which decision-making regarding children’s influenza vaccination may vary between fathers and mothers remains uncertain.
Conclusion
While there is increased awareness among parents about influenza vaccination, only 30.56% of them reported vaccinating their children against influenza in the past year. This underscores the need for interventions to boost vaccination rates, addressing not only knowledge and attitudes but also practical barriers that hinder parents from vaccinating their children. Strategies could involve targeted educational initiatives, enhanced access to vaccination services, and assistance for parents in scheduling and attending vaccination appointments. Encouraging physician recommendations for the influenza vaccine is vital and should be promoted in healthcare centers, clinics, and hospitals.
