Oxidative stress, an imbalance between reactive oxygen species and antioxidants, has been linked to impaired placental function and suboptimal fetal growth, yet trimester-specific associations remain poorly understood. We examined 561 mother-infant pairs from The Infant Development and Environmental Study (TIDES), measuring maternal urinary biomarkers of DNA oxidation (8- hydroxydeoxyguanosine (8-OHdG)), lipid peroxidation (malondialdehyde (MDA), and F2-isoprostanes), and protein oxidation (dityrosine (diY)) at first and second trimesters. Using generalized linear models, we examined prospective associations between oxidative stress and ultrasound-derived growth velocities. Early pregnancy oxidative stress biomarkers were persistently associated with reduced second and third trimester growth velocities. First trimester lipid peroxidation markers (8-PGF2α, 15-PGF2α, and 8,15-PGF2α) were associated with slower estimated fetal weight growth velocity in both second trimester (-0.81, -0.93, and -1.72 g/week per log-unit increase, respectively) and third trimester (-4.25, -5.60, and -6.74 g/week). Similarly, first trimester 8-OHdG and diY were associated with both second trimester (-1.31 and -1.17 g/week, respectively) and third trimester estimated fetal weight velocity (-8.01 and -6.75 g/week, respectively). Second trimester 8-OHdG and MDA were associated with slower third trimester estimated fetal weight velocity (-8.57 and -9.25 g/week, respectively). These results provide novel insights into trimester-specific associations between oxidative stress and fetal growth.

Environmental exposures can have adverse associations with perinatal health and birth outcomes. This study aimed to identify the overlap and association between urban areas of environmental risk and adverse perinatal health indicator hotspots in New York City. We examined 2101 census tracts representing 575,257 births from 2016 to 2020 recorded by the New York City Bureau of Vital Statistics looking at preterm birth, adolescent pregnancy, and pre-pregnancy obesity rates. The Getis-Ord Gi* statistic was used to identify geospatial hotspots of adverse indicators. We used multivariable logistic regression to assess associations between areas of environmental risk and odds of indicator hotspot status and Poisson regression to assess associations of hotspot overlap. Overall, 54.6% of environmental risk areas were hotspots for at least one adverse perinatal indicator, accounting for 63.7% of preterm birth hotspots, 93.7% of adolescent pregnancy hotspots, and 67.3% of pre-pregnancy obesity hotspots. Compared with non-risk areas, risk areas had greater odds of being a hotspot of preterm birth (aOR = 2.11; 95% CI 1.60-2.78), adolescent pregnancy (aOR = 32.8; 21.8-49.4), and pre-pregnancy obesity (aOR = 3.15; 2.56-3.87). Environmental risk areas were expected to have 3.36 times the number of overlapping hotspots after adjusting for parental birthplace and parity. The overlap between environmental risk areas and hotspots of adverse perinatal health indicators and the associations with individual indicators and overlapping hotspots suggest that environmental risk area designation may be a useful measure of perinatal health vulnerability for targeted community interventions.

OBJECTIVE:To examine if variation in session format and content of a prenatal obesity prevention program is associated with fruit and vegetable (FV) voucher redemption in Hispanic/Latino pregnant participants. METHODS:A secondary analysis of participants who received FV vouchers in a single-arm feasibility trial. We used linear regressions to assess associations between program session format (group vs individual) and FV voucher redemption rate, with session content (nutrition vs other lifestyle content [e.g., stress management or physical activity]) as a secondary predictor. RESULTS:Participants (n = 131) who attended a greater percentage of sessions in group format had increased voucher redemption rates (B = 0.37 [95% confidence interval, 0.05-0.70]. P = 0.03). Attending a higher percentage of group sessions with nutrition content rather than other lifestyle content was associated with a higher redemption rate (B = 0.19 [95% confidence interval, 0.002-0.38], P = 0.05). CONCLUSIONS AND IMPLICATIONS/CONCLUSIONS:Pairing FV voucher distribution with nutrition counseling delivered in a group format may increase utilization of FV vouchers.

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.

OBJECTIVE:This study aimed to quantify associations between newborn social risk factors and high infant weight-for-length (WFL) at 6 months. METHODS:We conducted a longitudinal, observational study using electronic health record data among infants in New York City. We included newborns with a primary care screening questionnaire for social risk factors (food insecurity, housing instability, transportation problems, and utility hardship) measured using the Accountable Health Communities Screening Tool. We conducted regression analyses to assess associations between social risk factors and high WFL, or the 97.7th percentile at 6 months. Secondary analyses included additional single-time-point and longitudinal weight outcomes (continuous and dichotomous). RESULTS:Among 1876 newborns, 77.3% identified as Hispanic/Latino, almost all had Medicaid insurance (96.6%), 355 (23.3%) had food insecurity risk, 149 (7.9%) had housing instability, 132 (7.0%) had transportation problems, and 110 (5.9%) had utility hardship. Newborns with utility hardship had higher odds of high WFL in unadjusted (OR 3.0, 95% CI: 1.8-5.2) and adjusted models (aOR 3.1, 95% CI: 1.7-5.6) accounting for infant, parent, and social risk factors. CONCLUSIONS:Newborn utility hardship was associated with obesity risk at age 6 months. Interventions to address newborn social risk factors should examine the effectiveness of utility shutoff protection to reduce excess infant weight gain.

OBJECTIVE:To explore attitudes and preferences related to remote nutrition education programming for Latino families in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) and primary care. DESIGN/METHODS:Community-engaged, qualitative, thematic analysis of interviews and focus groups. SETTING/METHODS:Prenatal and pediatric primary care and WIC sites in Manhattan, Queens, and Nassau Counties, New York. PARTICIPANTS/METHODS:Four stakeholder groups: (1) past participants of a primary care-based obesity prevention program (Starting Early Program Prenatal) for Latino families that transitioned to remote delivery because of coronavirus disease 2019 (n = 40), (2) Latina WIC participants, including pregnant women and mothers of young children (n = 40), (3) Starting Early Program Prenatal staff (n = 6), and (4) WIC staff (n = 16). PHENOMENON OF INTEREST/METHODS:Attitudes and preferences related to in-person vs remote nutrition education programming. ANALYSIS/METHODS:Focus groups and interviews were audio-recorded, transcribed, and analyzed for emergent themes using reflexive thematic analysis. RESULTS:Four themes emerged: (1) valuing in-person social connection while recognizing barriers to in-person gathering, (2) navigating distraction-related barriers to remote engagement, (3) consistent content delivery but uncertain quality of remote programs, and (4) coronavirus disease 2019 pandemic-related contextual factors. CONCLUSIONS AND IMPLICATIONS/CONCLUSIONS:Future remote programs in WIC may benefit from incorporating opportunities for social interaction, explicit discussion of anticipated barriers, and strategies to overcome them.

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.
