OBJECTIVE:To examine associations between oxidative stress and fetal weight across pregnancy. STUDY DESIGN/METHODS:Cohort study of pregnant participants from 2016-2021 in New York City with urinary lipid, protein, and DNA oxidative stress biomarkers (<18, 18-25, >25 weeks) and estimated fetal weight from ultrasound fetal biometry with the HadlockIII formula (20, 30, 36 weeks). RESULT/RESULTS:percentile. Oxidative stress biomarkers of protein damage were associated with larger estimated fetal weight at 20 (3.4 [95% CI: 1.2, 5.7]) and 36 weeks (16.5 [95% CI: 5.2, 27.8]). CONCLUSION/CONCLUSIONS:These findings advance our understanding of different oxidative stress pathways and their potential role in fetal growth.

Body image dissatisfaction shapes well-being across the life course. This study examines associations between parent-reported childhood experiences-adverse (ACEs) and positive (PCEs)-and body image dissatisfaction in adolescents. Using data from the National Survey of Children's Health, a nationally representative survey of US adolescents, we performed adjusted logistic regressions to assess associations between childhood experiences and body image dissatisfaction. Experiencing 1-2 and 3+ ACEs was associated with body image dissatisfaction compared to experiencing no ACEs (aOR: 1.24, 95% CI: 1.03-1.49; aOR 1.86, 95% CI: 1.39-2.48). PCEs (family resilience and neighborhood support) were associated with lower odds of body image dissatisfaction (aOR 0.57, 95% CI 0.48-0.69; aOR 0.75, 95% CI 0.64-0.86), even in adolescents with ACEs. In adolescents with 3+ ACEs, only family resilience had protective associations against body image dissatisfaction. These findings highlight how relational support may promote positive body image, particularly in adolescents experiencing adversity.

Although it is known that caregiver dietary behaviors influence child eating patterns, a gap remains in addressing the diet of a caregiver as much as their child in pediatric practice. A dyadic (caregiver-child) dietary approach would enhance the promotion of healthy eating patterns in children (and their caregivers) and achieve the population health goal of healthy eating across demographic groups. This study aimed to understand factors influencing dyadic dietary patterns (concordance, discordance) and contexts. Twenty professionals who provide nutrition-related expertise for families were recruited via maximum variation sampling. Qualitative thematic analysis of semi-structured interviews revealed 3 themes: (1) variable professional perspectives on what constitutes "healthy eating," (2) eating patterns of a child in the setting of variable caregiver eating practices, and (3) challenges to the promotion of a healthy caregiver-child dyadic diet within a social context. The results offer insight for future interventions that promote positive intergenerational transmission of health.

INTRODUCTION/BACKGROUND:Research has demonstrated that food insecurity during childhood is associated with worse physical and mental health in childhood. However, little is known about how food insecurity during childhood impacts health outcomes in young adulthood. METHODS:This study analyzed data from the Future of Families and Child Wellbeing Study (2024), a longitudinal birth cohort study of children born in 1998-2000. Childhood food insecurity trajectory groups from age 3 to 15 years were identified using group-based trajectory modeling. Associations between childhood food insecurity trajectory groups and young adult weight (BMI, overweight status, and obese status) and high self-reported health (good/excellent) at age 22 were modeled with multivariate linear and logistic regression. RESULTS:Three trajectories were identified among 4,296 participants: 66.9% were food secure, 7.5% were food insecure, and 25.6% transitioned from being food insecure-to-secure throughout childhood. In adjusted analyses, young adults assigned to the food insecure-to-secure trajectory group as children had higher BMI (B 0.82, 95% CI [0.07-1.58]) and higher odds of overweight status (OR 1.24, 95% CI [1.01-1.52]) than young adults assigned to the food secure trajectory group as children. Young adults in the food insecure trajectory group as children had lower odds of high self-reported health than those in the food secure trajectory group as children (OR 0.65, 95% CI [0.48-0.89]). CONCLUSIONS:Food insecurity in childhood is associated with high weight status and poor self-reported health in young adulthood. These findings highlight the importance of childhood food insecurity screening and interventions to promote health throughout the life course.

OBJECTIVE:Assess postintervention and dose effects of a child obesity prevention program, delivered from pregnancy through the age of 3 years, on child weight outcomes at the ages of 4 and 5 years among low-income Hispanic families. METHODS:As postintervention follow-up of the Starting Early Program (StEP) randomized controlled trial, StEP enrolled pregnant people in the third trimester to standard care control or the StEP intervention, which provided 15 nutrition and parenting support sessions. We analyzed differences in weight-for-age z scores (WFAz) and obesity status by group within intervention group analyses of program dose and moderation by adverse social drivers of health (SDoH). RESULTS:Weight data were available for 312 and 264 children aged 4 and 5 years, respectively. Mean WFAz (0.59 [1.08] vs 0.52 [1.16], P = .55; 0.60 [1.07] vs 0.58 [1.22], P = .86) and proportion with obesity (15.2% vs 15.6%, P = .90; 16.2% vs 19.5%, P = .47) were not different by intervention status at the ages of 4 and 5 years. The mean (SD) number of sessions attended was 8.7 (4.2) with the highest tertile attending 11 sessions or more. Lower WFAz and obesity prevalence were found for families with top tertile attendance. In moderation analysis, impacts on weight in children aged 5 years were greater for families with low social support compared high social support. CONCLUSION/CONCLUSIONS:Participation in StEP was not associated with postintervention differences in child weight. Higher attendance was associated with lower obesity prevalence, while treatment effects were greater for families with low social support. This highlights the need to evaluate program dose on long-term outcomes, especially for those with adverse SDoH.

OBJECTIVE:To explore how Sesame Workshop resources are perceived by Latino families with economic hardship and to highlight approaches for early heart healthy routine promotion. METHODS:We performed a purposive sampling of Latina mothers (n = 40) with young children experiencing economic hardship. Using an interview guide informed by the Consolidated Framework for Implementation Research, we recorded Spanish and English semistructured interviews, which were translated and transcribed verbatim. Partnering with Sesame Workshop, we iteratively incorporated Sesame Resources into interviews to query for acceptability. Using reflexive thematic analysis, we coded transcripts through textual analysis until saturation, prioritizing in vivo coding to capture participant voices. RESULTS:We constructed 3 themes. Parents connected with resources that 1) Reflect lived and multicultural experiences containing recognizable family scenes that can serve as tools to transfer a parent's own early routines or cultural rituals to their child. They appreciated resources that 2) Engage caregivers and children together, featuring elements for both children and adult caregivers with activities to highlight important caregivers and encourage shared play. Participants also reflected on how 3) Routines amplify family strengths and foster resilient reactions with feelings of decreased stress when daily practices become routines, promoting resilient reactions and supporting long-term goals when facing setbacks. CONCLUSIONS:An interdisciplinary partnership leveraged strengths of pediatric practitioners and Sesame Workshop to align future initiatives with the values and priorities of mothers of young children at risk for early obesity. Resultant themes inform strategies to promote heart healthy routines and relational health in young children with economic hardship.

BACKGROUND:Exposure to polycyclic aromatic hydrocarbons (PAHs) during childhood has been associated with altered growth and adiposity in children. The effects of prenatal exposure to PAHs on developmental programming of growth and adiposity are still unknown. OBJECTIVE:To study the association of prenatal exposure to PAHs with early childhood growth and adiposity measures. METHODS:In NYU Children's Health and Environment Study (2016-2019), we studied 880 mother-child pairs for maternal urinary PAH metabolites in early, mid, and late pregnancy and measured child weight, length/height, triceps, and subscapular skinfold thicknesses at 1, 2, 3, and 4 years. We used linear mixed models to investigate associations between average pregnancy exposure to PAHs and the z-scores of child repeated measures. The models were adjusted for sociodemographic and health-related factors. RESULTS:Children prenatally exposed to higher levels of PAHs had greater weight and length/height z scores. We found an interaction with time-point of child assessment, showing stronger associations at later ages. For instance, PAH exposure was associated with higher weight z-scores at 3 years: coefficient per Ln-unit increase in 2-NAP=0.25 (95%CI: 0.13, 0.37), 2-PHEN=0.25 (95%CI: 0.11, 0.39), 1-PYR=0.13 (95%CI: 0.02, 0.24), and 4-PHEN=0.09 (95%CI: 0.02, 0.15). Higher concentrations of 2-NAP (coefficient=0.21, 95%CI: 0.11, 0.31), 2-PHEN (coefficient=0.24, 95%CI: 0.12, 0.35), 3-PHEN (coefficient=0.13, 95%CI: 0.02, 0.24]), 4-PHEN (coefficient=0.09, 95%CI: 0.04, 0.15), and 1-PYR (coefficient=0.11, 95%CI: 0.02, 0.21) were associated with higher weight z-score at 4 years. CONCLUSION/CONCLUSIONS:Prenatal PAH exposure may contribute to the developmental programming of growth in childhood.

PURPOSE/OBJECTIVE:To investigate longitudinal associations between the presence of early childhood routines- predictable and repeatable functional practices that promote healthy growth, development, and relationships - and adolescent health outcomes. DESIGN/METHODS:Secondary data analysis. SETTING/METHODS:20 large U.S. cities. SUBJECTS/METHODS:2943 children with socioeconomic disadvantage from the Future of Families cohort. MEASURES/METHODS:Routines at age 3 (shared family meals, bedtime routine, daily reading); outcomes later in the same children at age 15 (healthy routines, overall health, psychological well-being). ANALYSIS/METHODS:Descriptive statistics, regression analyses. RESULTS:= 0.004]. Adolescent routines were concurrently associated with overall health and psychological well-being. We also detected two longitudinal patterns of associations suggesting multiple mechanisms for how early childhood routines influence later health and well-being. CONCLUSION/CONCLUSIONS:Early childhood routines predict adolescent routines, and may contribute to long term adolescent health outcomes. Future studies may promote childhood routines during critical developmental stages as a strength-based strategy to promote long-term health and well-being.
