ABSTRACT

We examined the association between childhood adversity and fecundability (the per-cycle probability of conception), and the extent to which childhood social support modified this association. We used data from 6,318 female participants aged 21-45 years in Pregnancy Study Online (PRESTO), a North American prospective preconception cohort study (2013-2022). Participants completed a baseline questionnaire, bimonthly follow-up questionnaires (until pregnancy or a censoring event), and a supplemental questionnaire on experiences across the life course including adverse childhood experiences (ACE) and social support (using the modified Berkman-Syme Social Network Index [SNI]). We used proportional probabilities regression models to compute fecundability ratios (FR) and 95% confidence intervals (CI), adjusting for potential confounders and precision variables. Adjusted FRs for ACE scores 1-3 and ≥4 vs. 0 were 0.91 (95% CI: 0.85, 0.97) and 0.84 (95% CI: 0.77, 0.91), respectively. FRs for ACE scores ≥4 vs. 0 were 0.86 (95% CI: 0.78, 0.94) among participants reporting high childhood social support (SNI ≥4) and 0.78 (95% CI: 0.56, 1.07) among participants reporting low childhood social support (SNI <4). Our findings confirm results from two previous studies and indicate that high childhood social support slightly buffered the effects of childhood adversity on fecundability.

ABSTRACT

We conducted a comparative cross-sectional study to compare the prevalence of exposure to workplace violence and intimate partner violence (IPV) in 125 female sex workers (FSWs) and 125 age-matched control women working in other professions (non-FSWs) and their children in El Alto, Bolivia. Violence exposure was assessed using the Demographic Health Survey Domestic Violence Module. To determine associations between work type and violence exposure, we conducted multivariate logistic regression. One-third of working mothers experienced sexual IPV, regardless of their profession. FSWs experienced higher rates of severe physical IPV and workplace violence. Children of FSWs were approximately three times more likely to be exposed to violence in the workplace. In Bolivia, strategies to reduce exposure to violence within the home and in FSW workplaces are paramount to minimizing negative impacts on women and their children. These findings have implications for policies to improve education, living wages, and social interventions to prevent and mitigate violence against women and children.

ABSTRACT

OBJECTIVE: To explore clinicians' perspectives about the impact of group well-child care (GWCC) on equitable health care delivery. METHODS: In this qualitative study, we conducted semistructured interviews with clinicians engaged in GWCC recruited via purposive and snowball sampling. We first conducted a deductive content analysis using constructs from Donabedian's framework for health care quality (structure, process, and outcomes) followed by inductive thematic analysis within these constructs. RESULTS: We completed 20 interviews with clinicians who deliver or research GWCC in 11 institutions across the United States. Four major themes around equitable health care delivery in GWCC emerged from clinicians' perspectives: 1) shifts in power dynamics (process); 2) enabling relational care, social support, and a sense of community (process, outcome); 3) centering multidisciplinary care delivery around patient and family needs (structure, process, and outcomes); and 4) unaddressed social and structural barriers limit patient and family participation. CONCLUSIONS: Clinicians perceived that GWCC enhances equity in health care delivery by shifting hierarchies in clinical visits and promoting relational, patient, and family-centered care. However, potential opportunities exist to further address provider implicit bias in group care delivery and structural inequities at the level of the health care institution. Clinicians underscored the need to address barriers to participation so that GWCC can more fully enhance equitable health care delivery.

ABSTRACT

Chemical hair straighteners ("relaxers") are used by millions of North Americans, particularly women of color. Hair relaxers may contain endocrine-disrupting compounds, which can harm fertility. We evaluated the association between hair relaxer use and fecundability among 11,274 participants from Pregnancy Study Online (PRESTO), a North American preconception cohort study. During 2014-2022, participants completed a baseline questionnaire in which they reported their history of relaxer use and completed follow-up questionnaires every 8 weeks for 12 months or until pregnancy, whichever came first. We used multivariable-adjusted proportional probabilities regression models to estimate fecundability ratios (FRs) and 95% confidence intervals (CIs). Relative to never use, fecundability was lower among current (FR = 0.81, 95% CI: 0.64, 1.03) and former (FR = 0.89, 95% CI: 0.81, 0.98) users of hair relaxers. FRs for first use of hair relaxers at ages <10, 10-19, and ≥20 years were 0.73 (95% CI: 0.55, 0.96), 0.93 (95% CI: 0.83, 1.04), and 0.85 (95% CI: 0.74, 0.98), respectively. Fecundability was lowest among those with longer durations of use (≥10 years vs. never: FR = 0.71, 95% CI: 0.54, 0.91) and more frequent use (≥5 times/year vs. never: FR = 0.82, 95% CI: 0.60, 1.11), but associations were nonmonotonic. In this preconception cohort study, use of chemical hair straighteners was associated with slightly reduced fecundability.

ABSTRACT

PURPOSE: Preventive health care, delivered through well child care visits, serves as a universal and primary entry point for promoting child wellbeing, yet children with lower socioeconomic status and children of color receive less consistent and lower quality preventive health care. Currently, limited research exists comparing models for delivering preventive care to children and their impact on longstanding racial/ethnic and socioeconomic inequities. DESCRIPTION: Practice-based research networks can help to advance health equity by more rapidly studying and scaling innovative, local models of care to reduce racial/ethnic and socioeconomic inequities in primary care and preventive care utilization. This paper outlines a framework of community engagement that can be utilized by practice-based research networks to advance health equity and details the application of the framework using the GROWBABY Research Network (GROup Wellness Visits for BABies and FamilY Research Network). ASSESSMENT: The GROWBABY Research Network launched in 2020, engaged clinical practices utilizing this unique model of group well childcare - CenteringParenting® - with the following goals: to promote collaboration among researchers, clinicians, patients, and community members; facilitate practice-based research; and increase the use of shared assessment measures and protocols. As a research collaborative, the GROWBABY Research Network connects clinical partners facing similar challenges and creates opportunities to draw upon the assets and strengths of the collective to identify solutions to the barriers to research participation. CONCLUSION: Primary care, practice-based research networks like the GROWBABY Research Network that intentionally integrate community engagement principles and community-based participatory research methods can advance equitable health care systems and improve child wellbeing.

ABSTRACT

Importance: Decades of inequitable policies in the US have yielded disparities in neighborhood quality, and some studies show that living in a socioeconomically disadvantaged neighborhood is associated with worse health outcomes, including reproductive health outcomes. However, no US studies to date have directly examined the association between residence in disadvantaged neighborhoods and fertility. Objective: To examine the association between residence in disadvantaged neighborhoods and fecundability, a sensitive marker of fertility with many health implications. Design, Setting, and Participants: This prospective preconception cohort study used the Pregnancy Study Online, for which baseline data were collected from June 19, 2013, through April 12, 2019. The study included 6356 participants who identified as female, were 21 to 45 years of age, were attempting conception without fertility treatment, and provided a valid residential address in the contiguous US at enrollment. Exposures: A standardized area deprivation index (ADI) derived at the census block group level applied to each residential address. Main Outcomes and Measures: Fecundability, the per-cycle probability of conception, via questionnaires that were completed every 8 weeks for 12 months, until conception or a censoring event. Proportional probabilities models were used to estimate fecundability ratios and 95% CIs for associations between ADI and fecundability. Restricted cubic splines were also implemented to examine nonlinearity. Models were adjusted for demographic characteristics and factors associated with fertility. The study's a priori hypothesis was that higher levels of neighborhood disadvantage would be associated with decreased fecundability. Results: Among 6356 participants, 3725 pregnancies were observed for 27 427 menstrual cycles of follow-up. The mean (SD) baseline age was 30.0 (4.1) years, and most participants were non-Hispanic White (5297 [83.3%]) and nulliparous (4179 [65.7%]). Comparing the top and bottom deciles of disadvantaged neighborhood status, adjusted fecundability ratios were 0.79 (95% CI, 0.66-0.96) for national-level ADI rankings and 0.77 (95% CI, 0.65-0.92) for within-state ADI rankings. Restricted cubic splines showed some evidence of nonlinearity in the association. Associations were slightly stronger among participants with lower annual incomes (<$50 000). Conclusions and Relevance: In this cohort study, residence in a socioeconomically disadvantaged neighborhood was associated with moderately decreased fecundability. If confirmed in other studies, these results suggest that investments to reduce disadvantaged neighborhood status may yield positive cobenefits for fertility.

ABSTRACT

INTRODUCTION: Group well-child care (GWCC) is an alternative to traditional pediatric well-child care designed to increase parental social support and peer learning. This mixed methods study explored the adaptation and implementation of GWCC to a virtual format during coronavirus disease 2019 (COVID-19 pandemic) among Spanish-speaking Latino immigrant families. METHOD: Interviews were conducted with eight providers and 10 mothers from May through September 2020. Qualitative analyses used a priori codes based on an implementation science framework. Quantitative data included demographics, the COVID-19 Impact Scale, and virtual group attendance. Bivariate analyses identified correlates of virtual visit attendance. RESULTS: Eighty percent of mothers reported the pandemic had moderately or extremely impacted at least one major life domain such as daily life, food security, or family conflict. Of 27 mothers offered virtual groups, 67% attended. Mothers who attended virtual groups reported lower English proficiency (p = .087) and fewer friends and family members with COVID-19 (M = 1.0 vs. 5.1, p < .05) than those who did not attend. Women described virtual GWCC as acceptable and a source of social support. Some described differences in group dynamics compared with in-person groups and had privacy concerns. Providers noted scheduling and billing challenges affecting feasibility and sustainability. They reported that visits with good attendance were productive. Mothers and pediatric providers offered recommendations to improve feasibility and privacy and address sustainability. DISCUSSION: Competing demands for those most impacted by COVID-19 may outweigh benefits of attendance. Virtual Spanish language GWCC appears acceptable and feasible for Spanish speaking Latina mothers. Thematic analysis and recommendations identify areas of improvement.

ABSTRACT

BACKGROUND: Childhood exposures to discarded needles pose a direct risk for infection with blood-borne pathogens and psychological trauma for caregivers and children. Little is known about environmental predictors of discarded needles relative to areas where children are frequent, such as schools. OBJECTIVE: We investigated spatiotemporal trends in discarded needle reports and the density near schools in Boston, Massachusetts, between 2016 and 2019. METHODS: We used the kernel density estimation (KDE) and a relative risk function (RRF) to explore their spatial distribution and temporal changes of discarded needles reported through the 311 service request system in Boston. The density of needle pick-up requests around schools was investigated by using Thiessen polygons. RESULTS: Between January 2016 and December 2019, 18,272 discarded needle reports were made. Publicly reported discarded needles in Boston sharply increased over the 4 years and the highest density of needles was found in 2 central neighborhoods. The density of reports of discarded needles near schools increased among the majority of schools. About 30% of schools demonstrated an increase of 100% or more in reports of discarded needles. CONCLUSION: This analysis provides insight into potential risk of exposure to needle stick injuries for children based on utilizing publicly available crowd-sourced data. Monitoring the density of discarded needles near schools may be a novel approach to improve public health efforts to distribute safe needle disposal locations and reduce injection drug use in public.

ABSTRACT

OBJECTIVE: To investigate the association of early life abuse with sleep disruption risk in adulthood among U.S. Black women. METHODS: We analyzed data from the Black Women's Health Study, a prospective cohort study. In 2005, 29,998 women completed a self-administered questionnaire on early-life experiences of abuse (child and teen) and exposure to danger at any life stage. Participants reported on their sleep quality (snoring and diagnosed sleep apnea) in 2001, whether their "sleep was restless" in 2005, and their average sleep duration in 2009. We used log-binomial regression models to derive risk ratios (RRs) and 95% confidence intervals (CIs) for the association of child/teen abuse and danger at any life stage with snoring, diagnosis of sleep apnea, restless sleep, and short sleep duration. RESULTS: Nearly 50% of participants reported one or more measure of sleep disruption in adulthood. Higher severity of physical abuse was associated with increased risk of sleep disruption and higher severity of sexual abuse was associated with increased risk for most sleep disruptions. The RR comparing child/teen physical and sexual abuse relative to no abuse was highest for diagnosed sleep apnea (2.03, 95% CI: 1.70, 2.41). Feeling in danger at any life stage (child, teen, adult, past year) was generally associated with greater increases in risk of sleep disruption among women with a history of early life abuse than among women without such a history. CONCLUSIONS: Our findings suggest that abuse as a child and/or teen is related to disrupted sleep in adulthood.

ABSTRACT

OBJECTIVES: To investigate whether adverse childhood experiences are associated with miscarriage. METHODS: The Gulf Resilience on Women's Health Consortium recruited from clinics and community organizations in Southern Louisiana, 2011-2016. Data from 1511 reproductive-aged women with at least one pregnancy were analyzed. Adverse childhood experiences including abuse, neglect, and family dysfunction, as a child (< age 12), and as an adolescent (12-17), were assessed. Outcome measures were self-reported miscarriage at first pregnancy and at any pregnancy, analyzed with logistic regression with adjustment for maternal age at pregnancy, race, BMI, education, marital and smoking status. RESULTS: Women reporting four or more adversities as a child and as a teen had higher odds of experiencing miscarriage at first pregnancy (AORchild 1.71, 95% CI 1.00-2.90; AORteen 1.73, 95% CI 1.05-2.87) and miscarriage at any pregnancy (AORchild 1.74, 95% CI 1.16-2.62; ORteen 1.65, 95% CI 1.10-2.45) compared to those with no adverse childhood experiences. Similar patterns of association were seen for other ACE sub-categories. CONCLUSIONS: Childhood adversities were associated with miscarriage. Further research is needed on the pathways which created this association, including psychological, behavioral, and physiological mechanisms and factors which can mitigate the effects of these outcomes.

ABSTRACT

BACKGROUND: Extensive data available in electronic health records (EHRs) have the potential to improve asthma care and understanding of factors influencing asthma outcomes. However, this work can be accomplished only when the EHR data allow for accurate measures of severity, which at present are complex and inconsistent. OBJECTIVE: Our aims were to create and evaluate a standardized pediatric asthma severity phenotype based in clinical asthma guidelines for use in EHR-based health initiatives and studies and also to examine the presence and absence of these data in relation to patient characteristics. METHODS: We developed an asthma severity computable phenotype and compared the concordance of different severity components contributing to the phenotype to trends in the literature. We used multivariable logistic regression to assess the presence of EHR data relevant to asthma severity. RESULTS: The asthma severity computable phenotype performs as expected in comparison with national statistics and the literature. Severity classification for a child is maximized when based on the long-term medication regimen component and minimized when based only on the symptom data component. Use of the severity phenotype results in better, clinically grounded classification. Children for whom severity could be ascertained from these EHR data were more likely to be seen for asthma in the outpatient setting and less likely to be older or Hispanic. Black children were less likely to have lung function testing data present. CONCLUSION: We developed a pragmatic computable phenotype for pediatric asthma severity that is transportable to other EHRs.

ABSTRACT

Background: We estimated the association between night shift work and fecundability among African American women. Methods: Black Women's Health Study participants (n = 560) aged 30-45 years reported their history of night shift work in 2005. Time to pregnancy for all pregnancies resulting in a livebirth was reported in 2011. We estimated the fecundability ratio (FR) and 95% confidence interval (CI) using proportional probabilities regression, accounting for multiple observations of individual women using generalized estimating equations. Results: We observed 4,417 months of pregnancy attempt time resulting in 390 births. After adjustment for covariates, women who reported ever working night shifts had 20% lower fecundability compared with those who never reported night shift work (FR = 0.80, 95% CI: 0.59-1.04). The FR for women reporting night shift work with a frequency of ≥1 time per month and a duration of ≥2 years was 0.65 (95% CI: 0.47-0.94) relative to women reporting no shift work. We observed a decrease in fecundability associated with ever working night shifts (FR = 0.74, 95% CI: 0.56-0.96) among women aged ≥35 years, but not among younger women (FR = 1.33, 95% CI: 0.78-2.28). Conclusion: A history of working night shifts was associated with reduced fecundability among older reproductive-aged African American women attempting pregnancy.

ABSTRACT

High-quality mother-child interactions during the first 2,000 days, from conception to age 5 years, are considered crucial for preventing obesity development during early life stages. However, mother-child dyads interact within and are influenced by broader socio-ecological contexts involved in shaping child development outcomes, including nutrition. Hence, the coexistence of both undernutrition and obesity has been noted in inequitable social conditions, with drivers of undernutrition and overnutrition in children sharing common elements, such as poverty and food insecurity. To date, a holistic life-course approach to childhood obesity prevention that includes an equitable developmental perspective has not emerged. The World Health Organization (WHO) Nurturing Care Framework provides the foundation for reframing the narrative to understand childhood obesity through the lens of an equitable nurturing care approach to child development from a life-course perspective. In this perspective, we outline our rationale for reframing the childhood narrative by integrating an equitable nurturing care approach to childhood obesity prevention. Four key elements of reframing the narrative include: (a) extending the focus from the current 1,000 to 2,000 days (conception to 5 years); (b) highlighting the importance of nurturing mutually responsive child-caregiver connections to age 5; (c) recognition of racism and related stressors, not solely race/ethnicity, as part of adverse child experiences and social determinants of obesity; and (d) addressing equity by codesigning interventions with socially marginalized families and communities. An equitable, asset-based engagement of families and communities could drive the transformation of policies, systems and social conditions to prevent childhood obesity.

ABSTRACT

PURPOSE: The purpose of this study is to evaluate socioeconomic determinants of fecundability. METHODS: Among 8654 female pregnancy planners from Pregnancy Study Online, a North American prospective cohort study (2013-2019), we examined associations between socioeconomic status and fecundability (the per-cycle probability of conception). Information on income and education was collected via baseline questionnaires. Bimonthly follow-up questionnaires were used to ascertain pregnancy status. We estimated fecundability ratios (FRs) and 95% confidence intervals (CIs) using proportional probabilities regression, controlling for potential confounders. RESULTS: Relative to an annual household income of greater than or equal to $150,000, adjusted FRs were 0.91 (95% CI: 0.83-1.01) for less than $50,000, 0.99 (95% CI: 0.92-1.07) for $50,000-$99,000, and 1.09 (95% CI: 1.01-1.18) for $100,000-$149,000. FRs for less than 12, 13-15, and 16 years of education, relative to greater than or equal to 17 years, were 0.90 (95% CI: 0.76-1.08), 0.84 (95% CI: 0.78-0.91), and 0.89 (95% CI: 0.84-0.95), respectively. Slightly stronger associations for income and education were seen among older women. CONCLUSIONS: Lower levels of education and income were associated with modestly reduced fecundability. These results demonstrate the presence of socioeconomic disparities in fecundability.

ABSTRACT

Introduction: Group-based models for well-child care have been shown to positively affect patient experience. One promising group well-child care model is CenteringParenting. However, clinician self-efficacy with delivery of the model is unknown and clinician satisfaction with the model has been understudied. Objectives: To investigate sense of self-efficacy, degree of satisfaction, and comfort with trauma-informed care (TIC) among diverse clinical providers implementing the CenteringParenting curriculum. We also examined the relationship between self-efficacy, satisfaction, and comfort with TIC, and delivery of the model. Methods: Electronic surveys were sent to CenteringParenting providers (N = 98) from 49 clinics. Providers (N = 41) from 24 clinical sites completed the survey, corresponding to a 42% individual and 49% site response rate. Surveys explored provider: satisfaction with the curriculum, perceived self-efficacy, and perspective on competency with TIC. Results: Providers indicated that the CenteringParenting model achieves each of its four objectives (means ranged from 4.10 to 4.52 for each objective, with 5 being the highest possible response). Providers rated their level of satisfaction (scale of 1 [unsatisfied] to 5 [very satisfied]) with their ability to address patient concerns higher with CenteringParenting in the group care setting (mean = 4.10) than in the individual care setting (mean = 3.55). Respondents demonstrated a high mean average Self-Efficacy in Group Care score of 93.63 (out of 110). Unadjusted logistical regression analyses demonstrated that higher provider Self-Efficacy in Group Care score (odds ratio [OR] = 1.08) and higher comfort with TIC (OR = 22.16) is associated with curriculum content being discussed with a facilitative approach. Conclusions: Providers from diverse clinical sites report high satisfaction with and self-efficacy in implementing the CenteringParenting model.

ABSTRACT

STUDY QUESTION: Is there an association between physical and sexual abuse occurring in childhood or adolescence and risk of laparoscopically-confirmed endometriosis? SUMMARY ANSWER: Early life sexual and physical abuse was associated with an increased risk of endometriosis. WHAT IS KNOWN ALREADY: Previous studies have reported that physical and sexual abuse are associated with chronic pelvic pain (CPP). However, only one study has examined the association between childhood physical abuse and laparoscopically-confirmed endometriosis, and did not observe an association with endometriosis risk. STUDY DESIGN, SIZE, DURATION: Prospective cohort study using data collected from 60 595 premenopausal women from 1989 to 2013 as part of the Nurses' Health Study II cohort. PARTICIPANTS/MATERIALS, SETTING, METHODS: Participants completed an exposure to violence victimization questionnaire in 2001. Cases were restricted to laparoscopically-confirmed endometriosis. Cox proportional hazards models were used to calculate rate ratios (RR) and 95% confidence intervals (CI). MAIN RESULTS AND THE ROLE OF CHANCE: Three thousand three hundred and ninety-four cases of laparoscopically-confirmed endometriosis were diagnosed during 24 years of follow-up. Compared to those reporting no physical or sexual abuse, the risk of endometriosis was greater among those who experienced severe physical abuse (RR = 1.20; 95% CI = 1.06, 1.37) or severe sexual abuse (RR = 1.49; 95% CI = 1.24, 1.79). There was a 79% increased risk of laparoscopically-confirmed endometriosis for women reporting severe-chronic abuse of multiple types (95% CI = 1.44, 2.22). The associations between abuse and endometriosis were stronger among women presenting without infertility, a group that was more likely to have been symptomatic with respect to pain. LIMITATIONS, REASONS FOR CAUTION: The violence exposure was recalled by the study participants and thus is subject to misclassification as well as recall bias for the cases who were diagnosed prior to 2001. However, our results were similar in a sensitivity analysis including only endometriosis cases incident after their violence history report. In addition, residual or unmeasured confounding is a possibility; however, we were able to adjust for a variety of potential early life confounders. Finally, selection bias is also a possibility if those who chose to return the violence questionnaire did so based jointly on abuse history and endometriosis risk. WIDER IMPLICATIONS OF THE FINDINGS: Early life sexual and physical abuse was associated with an increased risk of endometriosis. Severity, chronicity and accumulation of types of abuse were associated with greater risk. Understanding the mechanisms underlying these relations may better define the biologic impacts of abuse and the related pathophysiology of endometriosis.

ABSTRACT

Adverse experiences in childhood and adolescence, defined as subjectively perceived threats to the safety or security of the child's bodily integrity, family, or social structures, are known to be associated with cardiometabolic outcomes over the life course into adulthood. This American Heart Association scientific statement reviews the scientific literature on the influence of childhood adversity on cardiometabolic outcomes that constitute the greatest public health burden in the United States, including obesity, hypertension, type 2 diabetes mellitus, and cardiovascular disease. This statement also conceptually outlines pathways linking adversity to cardiometabolic health, identifies evidence gaps, and provides suggestions for future research to inform practice and policy. We note that, despite a lack of objective agreement on what subjectively qualifies as exposure to childhood adversity and a dearth of prospective studies, substantial evidence documents an association between childhood adversity and cardiometabolic outcomes across the life course. Future studies that focus on mechanisms, resiliency, and vulnerability factors would further strengthen the evidence and provide much-needed information on targets for effective interventions. Given that childhood adversities affect cardiometabolic health and multiple health domains across the life course, interventions that ameliorate these initial upstream exposures may be more appropriate than interventions remediating downstream cardiovascular disease risk factor effects later in life.
