Background Life course factors may be associated with pre-pregnancy body mass index and gestational weight gain; however, collecting information on pre-pregnancy exposures and pregnancy health in the same cohort is challenging. Objectives The Life-course Experiences And Pregnancy (LEAP) study aims to identify adolescent and young adult risk factors for pre-pregnancy weight and gestational weight gain (GWG). We built upon an existing cohort study to overcome challenges inherent to studying life course determinants of pregnancy health. Population Participants in an ongoing prospective cohort study of weight-related health who identified as women. Design Retrospective cohort study. Methods In 2019–2020, 1,252 women participating since adolescence in a cohort study of weight-related health were invited to complete an online reproductive history survey. Participants who reported a live birth were invited to release their prenatal, delivery, and postpartum medical records for validation of survey reports. Descriptive analyses were conducted to assess the characteristics of the overall cohort and the medical record validation subsample, and to describe adolescent and young adult characteristics of those with high (>80th percentile), moderate (20th-80th percentile), and low (<20th percentile) GWG z-score for gestational age and pre-pregnancy weight status. Preliminary results Nine hundred seventy-seven women (78%) completed the LEAP survey and 656 reported a live birth. Of these, 379 (58%) agreed to release medical records, and 250 records were abstracted (66% of the 379). Of the 977 survey respondents 769 (79%) reported attempting a pregnancy, and 656 (67%) reported at least one live birth. The validation subsample was similar to the overall cohort. Women with a high GWG had a higher adolescent BMI percentile and prevalence of unhealthy weight control behaviors than those with moderate or low GWG. Conclusions LEAP offers a valuable resource for identifying life course factors that may influence the health of pregnant people and their offspring.

This research identified whether adolescent religiosity was associated with body satisfaction and disordered eating in adolescence and early adulthood and explored gender/sex differences in these associations. Project EAT (Eating and Activity in Teens and Young Adults) is a longitudinal cohort study following participants from adolescence into young adulthood. For this analysis (N = 1620), religiosity (importance of religion and frequency of religious service participation) during adolescence was examined as a correlate of body satisfaction and disordered eating (binge eating, maladaptive behaviors intended to lose or maintain weight, eating to cope, and dieting) at the same life stage (EAT-II, 2003–2004, Mage = 19.4&nbsp;years) and during young adulthood (EAT-IV, 2015–2016, Mage = 31.5&nbsp;years). Analyses used linear and logistic regression models adjusted for demographics and adolescent body mass index. During adolescence, females who placed greater importance on religion had higher body satisfaction, 22% higher odds of binge eating, and 19% greater odds of dieting in the past year, while more frequent attendance of religious services was associated with higher body satisfaction and 37% greater odds of dieting past year. Among males, only frequent attendance of religious services was associated with higher adolescent body satisfaction. Longitudinally, among females, only frequent attendance of religious services in adolescence predicted higher levels of body satisfaction in young adulthood. No significant longitudinal associations were observed among males. Our findings contribute to understanding the complex interplay between religiosity, gender, and body satisfaction. Further research should explore cultural factors influencing these associations and qualitative aspects of religious experiences to inform nuanced interventions. Level of evidence: Level III, cohort study.

Background: Weight-related self-monitoring (WRSM) apps are used by millions, but the effects of their use remain unclear. This study examined longitudinal relationships between WRSM and disordered eating among a population-based sample of emerging adults. Methods: Participants (n = 138) were recruited from EAT 2010–2018 (Eating and Activity over Time study) to participate in a mixed-methods (quantitative and qualitative) longitudinal study to understand the impacts of WRSM. In 2018, participants (Mage=21.7 ± 1.9 years) reported motivations for use and types of WRSM apps used. Dependent variables collected in 2022 (Mage=25.7 ± 1.9 years) included past year total number of disordered weight control behaviors, disordered muscle building behaviors, compulsive exercise, and binge eating. Linear and logistic regressions were used adjusting for sociodemographics, body mass index, and baseline disordered eating. Semi-structured interviews (n = 25) were analyzed using inductive thematic analysis. Results: Participants using WRSM apps for weight management demonstrated an increase in disordered weight control behaviors over time (β = 0.894, p =.012). Using WRSM apps for “healthy” eating was marginally associated with an increase in disordered weight control behaviors. (β = 0.673, p =.052). Qualitatively, participants reported varied temporality between WRSM and disordered eating, but believed that app use encouraged restriction/binge cycles and normalized disordered eating. Conclusions: Findings suggest there may be individual variation in the relationships between WRSM and disordered eating, but that using WRSM apps with the motivation of managing eating or weight may increase disordered eating in some. Additionally, WRSM apps may normalize or encourage disordered eating. Therefore, safeguards, including screening and monitoring, are needed to ensure WRSM does not cause or escalate harm among WRSM users.

Purpose: To evaluate cross-sectional and longitudinal associations between controlling parental feeding practices in adolescence (i.e., restrictive feeding and pressure-to-eat [PE]) and intuitive eating (IE) in adolescence and emerging adulthood; and explore child gender and parental concern about child weight as moderators. Methods: The sample included participants (N = 1,383) from the population-based EAT 2010–2018 study who provided data in adolescence (14.4 ± 2.0 years) and emerging adulthood (22.0 ± 2.0 years) and had at least one caregiver complete surveys in adolescence. Generalized estimating equations evaluated cross-sectional and longitudinal associations between restrictive feeding and PE in adolescence and IE in adolescence and emerging adulthood. Interactions with gender and parental concern over child weight in adolescence were explored. Results: Restrictive feeding was cross-sectionally associated with lower IE in adolescence (b = −0.04), though evidence of moderation by parental weight concern indicated this association was only observed in the context of low parental weight concern. Greater PE was associated with lower adolescent IE among boys but higher IE among girls. Longitudinally, the association between PE in adolescence and IE in emerging adulthood differed by parental weight concern; greater PE predicted higher emerging adult IE at high parental weight concern, but lower IE at low parental weight concern. Discussion: Controlling feeding practices in adolescence displayed differential associations with child IE in adolescence and emerging adulthood based on child gender and parental concern over child weight. Notably, PE was associated with greater IE among adolescent girls but lower IE among boys. Results suggest that parental feeding is a valuable intervention target.

Background: Numerous observational studies show associations between family meal frequency and markers of child cardiovascular health including healthful diet quality and lower weight status. Some studies also show the "quality" of family meals, including dietary quality of the food served and the interpersonal atmosphere during meals, is associated with markers of child cardiovascular health. Additionally, prior intervention research indicates that immediate feedback on health behaviors (e.g., ecological momentary intervention (EMI), video feedback) increases the likelihood of behavior change. However, limited studies have tested the combination of these components in a rigorous clinical trial. The main aim of this paper is to describe the Family Matters study design, data collection protocols, measures, intervention components, process evaluation, and analysis plan. Methods/design: The Family Matters intervention utilizes state-of-the-art intervention methods including EMI, video feedback, and home visiting by Community Health Workers (CHWs) to examine whether increasing the quantity (i.e., frequency) and quality of family meals (i.e., diet quality, interpersonal atmosphere) improves child cardiovascular health. Family Matters is an individual randomized controlled trial that tests combinations of the above factors across three study Arms: (1) EMI; (2) EMI+Virtual Home Visiting with CHW+Video Feedback; and (3) EMI+Hybrid Home Visiting with CHW+Video Feedback. The intervention will be carried out across 6 months with children ages 5-10 (n=525) with increased risk for cardiovascular disease (i.e., BMI ≥75%ile) from low income and racially/ethnically diverse households and their families. Data collection will occur at baseline, post-intervention, and 6 months post-intervention. Primary outcomes include child weight, diet quality, and neck circumference. Discussion: This study will be the first to our knowledge to use multiple innovative methods simultaneously including ecological momentary assessment, intervention, video feedback and home visiting with CHWs within the novel intervention context of family meals to evaluate which combination of intervention components are most effective in improving child cardiovascular health. The Family Matters intervention has high potential public health impact as it aims to change clinical practice by creating a new model of care for child cardiovascular health in primary care. Trial Registration: This trial is registered in clinicaltrials.gov (Trial ID: NCT02669797). Date recorded 5/02/22.

Given emerging adulthood is a period of increased independence, it is unclear how much contact emerging adults have with their parents, how this communication occurs, and how frequency of communication differs across sociodemographic characteristics. The main aim of this study was to examine communication patterns and modalities between emerging adults and their parents. Data are from an 8-year longitudinal, population-based study of socio-economically and racially/ethnically diverse adolescents followed into emerging adulthood (n = 1539; mean age = 22.1; 53.1% female). Latent profile analysis results supported a 5-class model, in which classes were characterized by patterns of frequency of communication with parents across different modalities. The most common communication modality included medium levels of engagement (i.e., few times/week), with both parents, and was in-person or via the phone (i.e., calls, text messages, email). Results differed by race/ethnicity. Findings from this exploratory study may be useful for supporting positive communication patterns between emerging adults and their parents and may inform what intervention delivery format (e.g., phone, social media-based, in-person) may be more effective for certain parent/emerging adult subgroups engaging in family-based interventions.
