<title>Purpose</title>
<p>The relation between fear of childbirth (FoC) and gestational age is inconclusive, and self-reported need for help regarding this fear has never been investigated. This study aimed to determine the prevalence and course of FoC according to gestational age, to identify risk factors for the development of FoC, the influence of this fear on preferred mode of delivery, and self-reported need for help.</p>
</sec>
<sec>
<title>Methods</title>
<p>Nulliparous pregnant women of all gestational ages completed an online survey. The study consisted of a cross-sectional and a longitudinal analysis. Women who completed the survey in the first or second trimester (T<sub>0</sub>) were approached again in their third trimester (T<sub>1</sub>). The Wijma Delivery Expectancy Questionnaire Version A (W-DEQ A) was used with a cut-off score&#x2009;&#x2265;&#x2009;85 to define presence of fear of childbirth. Questionnaires indexing social support, anxiety, symptoms of depression, preferred mode of delivery, and self-reported need for help were included.</p>
</sec>
<sec>
<title>Results</title>
<p>In total, 364 women were enrolled at T<sub>0</sub>, and 118 out of 184 eligible women were included in the longitudinal analysis. Point prevalence of FoC at T<sub>0</sub> was 18.4% with no significant difference between trimesters. In the longitudinal sample, the prevalence of FoC decreased from 18.6% (T<sub>0</sub>) to 11.0% (T<sub>1</sub>), <italic>p</italic>&#x2009;=&#x2009;0.004. Although mean scores for FoC decreased significantly, <italic>p</italic>&#x2009;&#x003C;&#x2009;0.001, scores increased in 41 (34.7%) women. The presence of FoC was associated with elevated anxiety, less family support, prenatal care of the obstetrician by choice, preference for a cesarean section, and for pain relief. Women with FoC were more likely to actively seek for help compared to women without FoC.</p>
</sec>
<sec>
<title>Conclusion</title>
<p>While FoC is common in each trimester, prevalence decreases over the course of pregnancy. Women with FoC are often actively seeking for help, suggesting that this fear should be addressed better, and help should be offered accordingly.</p>

<title>Introduction</title>
<p>Prevalence rates of fear of childbirth (FoC) differ across countries and measurement methods, ranging from 4 to 20% (<xref ref-type="bibr" rid="ref25">O&#x2019;Connell et al., 2017</xref>; <xref ref-type="bibr" rid="ref24">Nilsson et al., 2018</xref>). Literature on the etiology of FoC in nulliparous women suggests that its multifactorial cause of anxiety, depression, and low social support is found to be related to FoC (<xref ref-type="bibr" rid="ref39">Storksen et al., 2012</xref>; <xref ref-type="bibr" rid="ref19">Joki&#x0107;-Begi&#x0107; et al., 2014</xref>; <xref ref-type="bibr" rid="ref22">Lukasse et al., 2014</xref>; <xref ref-type="bibr" rid="ref11">Dencker et al., 2019</xref>). Thus, FoC is a common fear among pregnant women with some women being more vulnerable to the development of FoC than others.</p>
<p>Fear of childbirth could influence preferred and actual mode of delivery as well as psychological well-being in the postpartum period. Pregnant women with FoC have been found to be more likely prefer epidural analgesia in a vaginal delivery and a planned cesarean section (CS; <xref ref-type="bibr" rid="ref14">Haines et al., 2012</xref>; <xref ref-type="bibr" rid="ref28">Raisanen et al., 2014a</xref>; <xref ref-type="bibr" rid="ref32">Ryding et al., 2016</xref>; <xref ref-type="bibr" rid="ref35">Sitras et al., 2017</xref>). Yet, CS rates differ across countries, including views on performing cesarean sections upon maternal request without medical necessity (<xref ref-type="bibr" rid="ref13">Habiba et al., 2006</xref>; <xref ref-type="bibr" rid="ref3">Betr&#x00E1;n et al., 2016</xref>). This may explain why some studies found FoC to be related to a longer labor duration (<xref ref-type="bibr" rid="ref1">Adams et al., 2012</xref>) and a greater likelihood of an (unplanned) CS (<xref ref-type="bibr" rid="ref21">Laursen et al., 2009</xref>; <xref ref-type="bibr" rid="ref33">Ryding et al., 2015</xref>; <xref ref-type="bibr" rid="ref40">Takacs et al., 2019</xref>), whereas other studies could not detect a relation between FoC and (preferred) mode of delivery (<xref ref-type="bibr" rid="ref36">Sluijs et al., 2012</xref>; <xref ref-type="bibr" rid="ref18">Jespersen et al., 2014</xref>). Regarding the postpartum period, a meta-analysis found that FoC in pregnancy was associated with postpartum posttraumatic stress disorder (<xref ref-type="bibr" rid="ref2">Ayers et al., 2016</xref>). Hence, since FoC could lead to adverse physical and psychological outcomes during delivery and the postpartum period, identifying and treating FoC in pregnancy is important.</p>
<p>To find the optimum time to identify and treat women with FoC, knowledge about the course of FoC over time is important. However, regarding the course of FoC during pregnancy, literature shows conflicting results (<xref ref-type="bibr" rid="ref17">Huizink et al., 2004</xref>; <xref ref-type="bibr" rid="ref20">Laursen et al., 2008</xref>; <xref ref-type="bibr" rid="ref16">Hildingsson et al., 2011</xref>, <xref ref-type="bibr" rid="ref15">2017</xref>; <xref ref-type="bibr" rid="ref31">Rothenberger et al., 2011</xref>; <xref ref-type="bibr" rid="ref30">Richens et al., 2019</xref>). Longitudinal studies found either that FoC decreased (<xref ref-type="bibr" rid="ref17">Huizink et al., 2004</xref>; <xref ref-type="bibr" rid="ref15">Hildingsson et al., 2017</xref>) or increased (<xref ref-type="bibr" rid="ref16">Hildingsson et al., 2011</xref>) as pregnancy progressed. Also, no relation between FoC and gestational age (<xref ref-type="bibr" rid="ref31">Rothenberger et al., 2011</xref>) or conflicting patterns between women have been observed (<xref ref-type="bibr" rid="ref20">Laursen et al., 2008</xref>; <xref ref-type="bibr" rid="ref30">Richens et al., 2019</xref>). Since the course of FoC during pregnancy seems to differ across studies, the relation between FoC and gestational age is inconclusive.</p>
<p>Currently, there is no uniform guideline on screening for FoC in pregnancy. In addition, it is unclear whether pregnant women feel they are adequately provided with information about, and help with, FoC and whether women would prefer to receive additional help. To date, no studies have examined self-reported need for help in relation to FoC. If it proves to be the case that women themselves would like to receive additional help apart from the already provided pregnancy care, this would justify implementing help for FoC more standardly in the care than it is currently being done. Inherently, it is then also important to know when to screen for FoC and to provide this help. Therefore, the purpose of the present study was to determine the prevalence and course of FoC according to gestational age in nulliparous women and to evaluate self-reported need for help. We formulated the following main research questions. First, what is the prevalence and course of FoC in nulliparous pregnant women? And secondly, do nulliparous pregnant women express a need for help for FoC? Furthermore, since the literature has found multiple risk factors and consequences of FoC, we aimed to identify factors associated with FoC, and influence of FoC on the preferred mode of delivery.</p>

<title>Materials and Methods</title>
<p>This observational survey study consisted of a cross-sectional analysis and subgroup longitudinal analysis among a convenience sample of pregnant women. Women were recruited from February 2019 to January 2020 through a city hospital (OLVG) and several midwifery practices in Amsterdam, Netherlands. Nulliparous women received a flyer about the study after their appointment with their obstetrician or at the midwifery practice.</p>
<p>In the Netherlands, obstetric care is divided between community midwifes (primary care), obstetrician-gynecologists (secondary care), and academic referral centers (tertiary care). To distinguish which care is needed, risk selection takes place based upon a national list of recommendations [List of Obstetric Indications; <xref ref-type="bibr" rid="ref5">College voor zorgverzekeringen (College for Health Insurance), 2003</xref>]. For women with a low-risk profile, a community midwife can provide care. When needed, women are referred to an obstetrician. Women can also choose secondary care without medical necessity.</p>
<p>The flyer included information about the study, the inclusion criteria, and the address for the study website where they could receive more detailed information.<xref rid="fn0004" ref-type="fn"><sup>1</sup></xref> Furthermore, pregnant women were recruited through social media such as pregnancy websites, LinkedIn, Facebook, and Instagram where information about the study and the URL to the study website was also provided.</p>
<p>The website of the study contained the patient information and the informed consent form. When interested in participating in the study, women entered their personal e-mail address on the study&#x2019;s website. The personal e-mail address was then sent to one of the authors (YH) <italic>via</italic> a password-secured data file. Bias from possible repeated entry was prevented by ensuring e-mail addresses were not identical. The women were subsequently sent a personalized link to the online questionnaire (T<sub>0</sub>) through Castor EDC (<xref ref-type="bibr" rid="ref6">Castor, 2019</xref>). The questionnaire could be completed on any electronic device that was connected to the internet and there was no specific time limit to complete the survey. There was no interference from the researcher during this time. Once fully completed, the answers could not be changed. There were no printed questionnaires used. Women who completed the questionnaire in their first or second trimester received an e-mail with a personalized link around the 35th gestational week to complete the same questionnaire(s) once more (T<sub>1</sub>). Eligible for the study were nulliparous women of all gestational ages. Exclusion criteria were multiparous women (defined as a previous pregnancy of &#x2265;16&#x2009;weeks), women who were younger than 18&#x2009;years old, or who did not speak the Dutch language. Incomplete questionnaires were excluded.</p>
<p>The questionnaire included questions regarding demographics and obstetrical characteristics [i.e., age, gestational age, country of birth, partner, care led by midwife/gynecologist by choice/gynecologist for medical reasons, self-reported (history of) physical health, (history of) psychological treatment, medication use, previous pregnancies less than 16&#x2009;weeks, fertility treatment, planned pregnancy, pregnancy complications, preferred mode and place of birth], validated questionnaires for FoC, anxiety, depression, social support as well as questions pertaining to need for help. The questions on socio-demographic background factors and obstetrical characteristics were pretested and validated by subject matter experts including gynecologists (in training), psychologists and a psychiatrist. Since the other questionnaires used were well validated, we did not pretest those questions.</p>
<p>Fear of childbirth was assessed using the W-DEQ Version A (<xref ref-type="bibr" rid="ref43">Wijma et al., 1998</xref>). The W-DEQ A is a 33-item self-report questionnaire measuring FoC scored on a six-point Likert scale. Total scores vary from 0 to 165, with higher scores indicating higher FoC. The W-DEQ A has good psychometric properties with a high internal consistency (Cronbach&#x2019;s alpha &#x2265;0.87; <xref ref-type="bibr" rid="ref43">Wijma et al., 1998</xref>). A cut-off score of &#x2265;85 to indicate clinically relevant FoC has been mostly used and recommended (<xref ref-type="bibr" rid="ref43">Wijma et al., 1998</xref>; <xref ref-type="bibr" rid="ref4">Calderani et al., 2019</xref>). It has been translated to Dutch (<xref ref-type="bibr" rid="ref42">Wijma and Wijma, 2004</xref>).</p>
<p>Symptoms of anxiety and depression were measured using the Hospital Anxiety and Depression Scale (HADS), a validated self-report questionnaire consisting of 14 items to measure anxiety and depressive symptoms (<xref ref-type="bibr" rid="ref44">Zigmond and Snaith, 1983</xref>). Each item can be scored from 0 to 3 using a score range from 0 to 21 on each subscale with higher scores indicating more symptoms. It has been translated and validated in the Dutch population with a Cronbach&#x2019;s alpha of 0.84 and 0.79 for the anxiety and depression scale, respectively (<xref ref-type="bibr" rid="ref38">Spinhoven et al., 1997</xref>).</p>
<p>Social support was measured using the Multidimensional Scale of Perceived Social Support (MSPSS) which is a validated 12-item self-report questionnaire measuring support from family, friends, and a significant other (<xref ref-type="bibr" rid="ref45">Zimet et al., 1988</xref>). Each item is scored from 1 to 7 with higher scores indicating more social support. The MSPSS has been validated in the pregnant population, with Cronbach&#x2019;s alpha varying from 0.90 to 0.94 for the different subscales (<xref ref-type="bibr" rid="ref46">Zimet et al., 1990</xref>). It has been translated and validated in the Dutch population (<xref ref-type="bibr" rid="ref26">Pedersen et al., 2009</xref>).</p>
<p>Self-reported need for help was explored by one or multiple questions, depending on whether the woman was already receiving help. The question for need for help was designed using Prochaska&#x2019;s stages of behavioral change (<xref ref-type="bibr" rid="ref27">Prochaska et al., 1994</xref>), namely: &#x2018;For fear of childbirth <italic>(&#x201C;I do not need extra guidance right now, I have no problems at the moment&#x201D;</italic> vs. &#x201C;<italic>I am still doubting if I want extra guidance&#x201D;</italic> vs. &#x201C;<italic>I&#x2019;m actively searching for extra help&#x201D;</italic> vs. &#x201C;<italic>I am currently receiving extra help&#x201D; vs &#x201C;I have already received and completed help for fear of childbirth&#x201D;)</italic>. If the woman answered &#x201C;<italic>I do not need extra guidance right now, I have no problems at the moment</italic>&#x2019; no follow-up question was asked. Otherwise, participants were asked about their preference for the type of health professional and timing of additional help.</p>
<sec id="sec7">
<title>Statistical Analyses</title>
<p>Before analyzing the data, women were divided into three categories according to the gestational trimester (i.e., 0&#x2013;12&#x2009;weeks; 13&#x2013;27&#x2009;weeks; 28&#x2013;42&#x2009;weeks). Scores on the W-DEQ A were dichotomized using a cut-off score of &#x2265;85 to determine the presence of FoC (<xref ref-type="bibr" rid="ref43">Wijma et al., 1998</xref>). Descriptive statistics were used to describe socio-demographic and clinical data in absolute numbers and percentages. Groups were divided according to the presence of FoC yes/no. A Mann&#x2013;Whitney U test was conducted comparing age and gestational age. A Chi-square test was used to compare categorical variables. The effect of gestational age on FoC was determined by performing a one-way ANOVA and Pearson&#x2019;s Chi-square test. For the longitudinal analyses, change in W-DEQ A scores was analyzed by a paired samples t-test. A McNemar analysis was performed to analyze within-patient differences in prevalence rates over time. Logistic regression analyses were performed to identify potential predictors for the course of FoC (increase vs. decrease in scores on FoC). To assess potential significant variables and confounders, univariable regression analyses were carried out while potential risk factors for FoC, the preferred mode of delivery (vaginal birth or cesarean section, and pain relief), and preferred place of birth (at home or in the hospital) were determined using multivariable logistic regression analyses. To explore self-reported need for help for FoC, a separate logistic regression analysis was performed using the question on the need for help as a predictor of the presence of FoC. Only complete surveys were included in the analyses so there were no missing data.</p>
<p>Drop-out analyses were conducted to research potential differences between responders and drop-outs at T<sub>0</sub> and T<sub>1</sub> (i.e., lost to follow-up or incomplete questionnaires). Means and standard deviations are given as (M&#x2009;&#x00B1;&#x2009;SD). When data were not normally distributed, median and interquartile ranges are presented. Statistical differences were indicated as <italic>p</italic>&#x2009;&#x003C;&#x2009;0.05 (reported <italic>P</italic> is two-sided). Results of regression analyses are presented as unadjusted and adjusted odds ratios (OR) with a 95% confidence interval. All analyses were performed with the Statistical Package for Social Sciences (SPSS) version 24.0 (<xref ref-type="bibr" rid="ref9">Corp, 2016</xref>).</p>

<title>Ethical Approval</title>
<p>Informed consent was obtained by actively checking a box agreeing to participate in the study, which was obligatory, and thereafter leaving their personal e-mail address. Furthermore, participants were provided an option to download the patient information and informed consent form. This study was exempted from ethical approval by the Medical Research Ethics Committees United (MEC-U) in Nieuwegein, Netherlands (reference number W18.188).</p>

<p>In total, 566 women agreed to participate, of which 378 (66.8%) completed the questionnaire at T<sub>0</sub>. Fourteen women were excluded because of unknown gestational age (<italic>n</italic>&#x2009;=&#x2009;12) or being multiparous (<italic>n</italic>&#x2009;=&#x2009;2), leaving 364 women to be included in the analyses.

<title>Self-Reported Need for Help</title>
<p>Women with FoC were more likely to be still in doubt whether they wanted extra help, actively seeking for help, or already receiving extra help compared to women without FoC (<xref rid="tab5" ref-type="table">Table 5</xref>). There was no statistically significant difference between the need for help and receiving care from a midwife, an obstetrician by medical necessity, or by choice, <italic>&#x03C7;</italic><sup>2</sup> (4, <italic>N</italic>&#x2009;=&#x2009;364)&#x2009;=&#x2009;7.32, <italic>p</italic>&#x2009;=&#x2009;0.120.</p>

<title>Discussion</title>
<p>This study used both a cross-sectional as well as a longitudinal group, to research the prevalence and course of FoC during pregnancy. In support of our main hypothesis, results showed that FoC was common among women with an average prevalence rate of 18.4%. In our longitudinal sample, both prevalence and mean score of FoC significantly decreased over time. Further, the presence of FoC was found to be related to less family support, elevated anxiety, and prenatal care of the obstetrician by choice. Regarding the influence of FoC on preferred mode of delivery, women with FoC were more likely to prefer a cesarean section and pain relief, compared to those without FoC. Another important finding was that women with FoC were more likely to be actively seeking for help compared to women without FoC.</p>
<p>Our results on the prevalence and course of FoC are partially in line with previous literature (<xref ref-type="bibr" rid="ref17">Huizink et al., 2004</xref>; <xref ref-type="bibr" rid="ref23">Nieminen et al., 2009</xref>; <xref ref-type="bibr" rid="ref22">Lukasse et al., 2014</xref>; <xref ref-type="bibr" rid="ref15">Hildingsson et al., 2017</xref>; <xref ref-type="bibr" rid="ref25">O&#x2019;Connell et al., 2017</xref>; <xref ref-type="bibr" rid="ref12">Fairbrother et al., 2018</xref>). The prevalence rate of FoC (18.4%) in the present study is somewhat higher than in a recent meta-analysis (<xref ref-type="bibr" rid="ref25">O&#x2019;Connell et al., 2017</xref>) albeit there is a wide variety in prevalence rates across countries. In line with previous studies (<xref ref-type="bibr" rid="ref23">Nieminen et al., 2009</xref>; <xref ref-type="bibr" rid="ref22">Lukasse et al., 2014</xref>; <xref ref-type="bibr" rid="ref12">Fairbrother et al., 2018</xref>), we did not observe a relation between gestational age and FoC in the cross-sectional group overall. However, for women with FoC, we did see that women in their third trimester scored significantly lower on FoC than those in their first trimester. In the longitudinal sample, we found an overall decrease in prevalence and mean scores of FoC over the course of pregnancy. Yet, patterns differed individually with a minority of women showing an increase in scores over time while no predictors for this increase were found. Importantly, even though in some women scores on FoC increased, no women in our sample developed clinically relevant FoC over the course of their pregnancy, which is opposed to women in a previous study who did develop FoC over time as measured by the Fear of Birth Scale (<xref ref-type="bibr" rid="ref15">Hildingsson et al., 2017</xref>). Furthermore, women either had clinically relevant FoC throughout their pregnancy, or FoC decreased to below the cut-off in the third trimester. This suggests that screening negative at the beginning of pregnancy may reduce the likelihood of developing FoC over time while the other way around is more plausible in that FoC decreases later on in pregnancy. Therefore, we suggest that women should be screened for FoC at the beginning of pregnancy. Next, women should be counseled about treatment options for FoC and the possibility of spontaneous recovery. If a woman chooses to wait with treatment, it is important to monitor FoC throughout pregnancy.</p>
<p>We found three risk factors to be related to FoC. Firstly, compared to women without FoC, women with FoC reported a higher level of general symptoms of anxiety, which is consistent with previous literature (<xref ref-type="bibr" rid="ref11">Dencker et al., 2019</xref>). Secondly, less social support from family members was related to FoC, but this was not demonstrated regarding support from friends or significant others. A possible explanation for this finding might be the high level of overall social support in our sample; for instance, almost all participating women had a partner. Thirdly, women with FoC and an uncomplicated pregnancy more often chose to have prenatal care by an obstetrician. It could be that choosing prenatal care from an obstetrician might not be a risk factor for FoC, but rather reflecting a sense of security the hospital embodies, and thereby a consequence of FoC rather than a risk factor. In contrast to other studies (<xref ref-type="bibr" rid="ref20">Laursen et al., 2008</xref>; <xref ref-type="bibr" rid="ref39">Storksen et al., 2012</xref>; <xref ref-type="bibr" rid="ref11">Dencker et al., 2019</xref>), we did not find a significant relation between FoC and symptoms of depression, which may be explained by the overall low scores on depression in our study.</p>
<p>Regarding the preferred mode of delivery, women with FoC were more inclined to have a preference for a cesarean section and for pain relief during delivery, which is also in line with previous literature (<xref ref-type="bibr" rid="ref23">Nieminen et al., 2009</xref>; <xref ref-type="bibr" rid="ref37">Sluijs et al., 2020</xref>).</p>
<p>Regarding our aim to evaluate self-reported need for help for FoC, we found that women with FoC were often actively seeking additional help. This suggests that discussing FoC with a healthcare professional may not be standard practice nor sufficient to help and support women with these problems. This notion is supported by a recent study that concluded midwives should acquire more in-depth knowledge about FoC (<xref ref-type="bibr" rid="ref10">de Vries et al., 2020</xref>). Accordingly, it is important that after screening positive for FoC, women are referred to a trained specialist on FoC, preferably a psychologist.</p>
<p>Both strengths and limitations should be recognized. One strength is that this study is the first observational study with both a cross-sectional and a longitudinal sample to study the relation between FoC and gestational age in nulliparous pregnant women while using the validated W-DEQ A questionnaire to measure FoC. Secondly, asking women whether they would like to receive help for FoC provides in-depth insight into the perspective of pregnant women and willingness for treatment of FoC. Besides mentioning these strengths, some limitations need to be noted. No significant differences were found between trimesters on the W-DEQ A score of the total sample, albeit a post-hoc power analysis showed that with the current sample size and reported means, power was &#x003C;15% to detect significant differences in this group. Yet, the statistical power to detect significant differences was 99% for our longitudinal sample. Secondly, while all other demographic variables were similar, drop-out analyses at T<sub>0</sub> and T<sub>1</sub> revealed that completers significantly more often had a history of psychological treatment (T<sub>0</sub>) and a high educational level (T<sub>0</sub> and T<sub>1</sub>) in comparison to drop-outs, which may have led to attrition bias. Although efforts were made to create a diverse sample by recruiting women from multiple settings, compared to national data from the Netherlands, our sample was more often born in the Netherlands (94.2 vs. 76.8%; <xref ref-type="bibr" rid="ref7">Central Bureau for Statistics, 2020a</xref>) and more often had a high educational level (71.7% vs. 53.6%; <xref ref-type="bibr" rid="ref8">Central Bureau for Statistics, 2020b</xref>). These differences in country of birth and educational level may have led to an under-reporting of FoC. Namely, studies have found that risk factors for FoC include a low educational level (<xref ref-type="bibr" rid="ref20">Laursen et al., 2008</xref>; <xref ref-type="bibr" rid="ref34">Salomonsson et al., 2013</xref>; <xref ref-type="bibr" rid="ref33">Ryding et al., 2015</xref>; <xref ref-type="bibr" rid="ref12">Fairbrother et al., 2018</xref>) and being foreign born (<xref ref-type="bibr" rid="ref41">Ternstr&#x00F6;m et al., 2015</xref>). Therefore, prevalence may even be higher in the general pregnant population, underlying the importance of being attentive to FoC in pregnancy. However, other studies have not found such an association with educational level (<xref ref-type="bibr" rid="ref23">Nieminen et al., 2009</xref>) or report a higher risk of FoC in women with a high educational level (<xref ref-type="bibr" rid="ref29">Raisanen et al., 2014b</xref>). Future studies should aim to include a more diverse sample of pregnant women from remote areas and areas of low socioeconomic status, and to distribute a survey in multiple languages.</p>

<title>Conclusion</title>
<p>Fear of childbirth appeared prevalent in almost one in five women in each trimester and may decrease over time while women expressed a need for help. This highlights the need for standardized care of FoC and research into the application of screening tools and evidence-based treatments for those suffering from FoC. When pregnant women present themselves to the obstetrician, a thorough evaluation of patients&#x2019; social system is recommended, and reasons for choosing medical care should be asked for while being attentive to women who suffer from general anxiety. Attention should be given to requests for delivery by a planned CS without the medical necessity to rule out the possibility of an underlying FoC. Given the combination of a high prevalence and self-reported need for help, our recommendation would be that women are routinely screened for FoC at the beginning of pregnancy. More obstetricians and midwives should be aware of what possible treatment options are and where to find these so that women can be guided.</p>
