OBJECTIVE:To assess associations between exposure to intrauterine SARS-CoV-2 and subsequent child neurodevelopment in a large, diverse cohort with confirmation of maternal SARS-CoV-2 status. STUDY DESIGN/METHODS:edition (ASQ-3) and at 18 months with the ASQ Social-Emotional (ASQ-SE) and the Modified Checklist for Autism in Toddlers-Revised (M-CHAT-R). We compared exposed and unexposed infants' ASQ-3 total and subdomain scores, ASQ-SE and M-CHAT-R scores, and proportions meeting published referral thresholds, using multivariable linear and logistic regression. RESULTS:Among 1179 participants enrolled, 1008 (85.5%) had exposure, with 806 (80.0%) exposed during Omicron predominance. Of those with known timing, 349 (41.4%) and 295 (35.0%) were exposed in the second and third trimesters of pregnancy respectively. Exposure was not associated with differences in ASQ-3 (adjusted difference: -0.61, 95% CI: -10.03, 8.81) or ASQ-3 subdomains at 12 months, ASQ-SE at 18 months (adjusted difference: 0.19, 95% CI: -4.02, 4.41), or M-CHAT-R scores. Findings were similar for proportions meeting referral thresholds, and when stratified by variant or by trimester. CONCLUSIONS:In this multicenter cohort largely exposed since Omicron and in second or third trimester, intrauterine SARS-CoV-2 exposure was not associated with neurodevelopmental screening outcomes through 18 months of age. Further assessments of the impact of intrauterine SARS-CoV-2 on neurodevelopment beyond 18 months of age are needed.

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.

BACKGROUND:There is growing interest in understanding the link between early life exposures to ambient air pollution and childhood blood pressure; however, existing findings, largely from single site/cohort studies, are inconclusive. METHODS:(per 10-ppb) exposures with blood pressure outcomes were estimated using linear and Poisson regressions adjusted for sociodemographic, lifestyle, temporal, and spatial confounders. RESULTS:with both SBP (β: -2.42, 95 %CI: -4.70, -0.14) and DBP (β: -1.94, 95 %CI: -3.81, -0.08) percentiles were suggested. CONCLUSION/CONCLUSIONS:and blood pressure was counterintuitive and warrants further investigation.

BACKGROUND:The school environment plays a vital role in shaping children's health and well-being. Nutrition education supports health promotion and disease prevention; however, it is unclear how comprehensive curricula are in the content they cover. This study explored the content of K-12 nutrition curricula in US public schools. METHODS:We analyzed nutrition education curricula from the 2023-2024 school year across a target sample of 50 states. Materials were collected through online searches and phone calls to districts and schools. We employed content analysis to assess nutrition concepts and modes of curriculum delivery, using a codebook to systematically code the curricula. RESULTS:We obtained 110 curricula across 38 states. Common concepts included macronutrients (54.5%), micronutrients (55.4%), food groups (58%), and the benefits of good nutrition (69%). Fewer curricula addressed consequences of poor nutrition (44.5%) or behavioral changes like portion size (38.1%). Most curricula (87.2%) used didactic methods, with only 19.5% incorporating hands-on activities. Broader topics such as environmental impacts of food choices (17.2%) were less common. IMPLICATIONS FOR SCHOOL HEALTH POLICY, PRACTICE, AND EQUITY/UNASSIGNED:Nutrition education plays a critical role in shaping children's long-term health outcomes; however, challenges remain in ensuring consistent and high-quality instruction. CONCLUSIONS:Nutrition education in the US focuses on core nutrition concepts and often relies on didactic methods, with limited hands-on activities. This highlights the need for more engaging, standardized programs.

MOTIVATION/BACKGROUND:Large-scale prospective cohort studies collect longitudinal biospecimens alongside time-to-event outcomes to investigate biomarker dynamics in relation to disease risk. The nested case-control (NCC) design provides a cost-effective alternative to full cohort biomarker studies while preserving statistical efficiency. Despite advances in joint modeling for longitudinal and time-to-event outcomes, few approaches address the unique challenges posed by NCC sampling, non-normally distributed biomarkers, and competing survival outcomes. RESULTS:Motivated by the TEDDY study, we propose "JM-NCC", a joint modeling framework designed for NCC studies with competing events. It integrates a generalized linear mixed-effects model for potentially non-normally distributed biomarkers with a cause-specific hazard model for competing risks. Two estimation methods are developed. fJM-NCC leverages NCC sub-cohort longitudinal biomarker data and full cohort survival and clinical metadata, while wJM-NCC uses only NCC sub-cohort data. Both simulation studies and an application to TEDDY microbiome dataset demonstrate the robustness and efficiency of the proposed methods.

Environmental exposures are contributors to morbidity and mortality, yet the potential protective role of health insurance in mitigating these effects remains underexplored. We used data from the 1999-2000 and 2001-2002 cycles of the National Health and Nutrition Examination Survey (NHANES) to examine whether health insurance status is associated with the chemical exposome and whether being insured modifies relationships of environmental exposures with epigenetic aging biomarkers of morbidity and mortality (GrimAge2 and DunedinPoAm). Among 2315 adults aged 50 - 84 years, we evaluated 64 chemical exposures. In covariate, socioeconomic status-adjusted models, being insured compared to being uninsured was marginally associated with 0.21-SD lower blood lead levels (95% CI: -0.39, -0.04, P = 0.03) and 0.29-SD higher PCB180 levels (95% CI: 0.003, 0.57, P = 0.048). In leukocyte- and covariate-adjusted models, insurance attenuated the relationship of lead with GrimAge2 (Insured: β = 0.08-years, 95% CI: -0.08, 0.24; Uninsured β = 0.65-years, 95% CI: 0.11, 1.20; P _interaction = 0.04) and DunedinPoAm (Insured: β = 0.001, 95% CI: -0.002, 0.003; Uninsured β = 0.01, 95% CI 0.0001, 0.02; P _interaction = 0.047). Similar trends were also observed for cadmium, cotinine, and PCB180 but not statistically different between insurance categories. These findings suggest that health insurance may serve as a protective factor against the biological aging impacts of certain environmental exposures, possibly through improved access to exposure monitoring and preventive/therapeutic care. While not a substitute for environmental policy or exposure remediation, insurance may represent a small, complementary, and more immediately actionable tool to help reduce harm. However, given the small magnitude of model estimates, results should be interpreted with caution regarding their practical significance.

BACKGROUND/UNASSIGNED:To investigate the proteomic signatures of heart failure (HF) in diabetes. The underlying mechanisms of the elevated risk of HF in diabetes are unknown. METHODS/UNASSIGNED:In 10 189 ARIC study (Atherosclerosis Risk in Communities) participants free of HF (mean age 57±7 years, 56% women, 22% Black adults, 14% with diabetes), we conducted discovery and internal validation for the associations of 4955 plasma proteins with HF by diabetes status. We performed (1) Cox regression to identify proteins associated with HF by diabetes status, (2) external validation in the MESA study (Multi-Ethnic Study of Atherosclerosis, n=5233, 633 with diabetes), and (3) pathway analyses for identified proteins. RESULTS/UNASSIGNED:<0.05/19). Six of the internally validated proteins replicated in MESA (false discovery rate, q<0.05). Five proteins were specifically associated with HF in those with diabetes: 4 are novel (inactive tyrosine-protein kinase 7, chondroadherin, leucine-rich repeat, and immunoglobulin-like domain-containing nogo receptor-interacting protein 1 and fibulin-5) and 1 is the previously known (cartilage intermediate layer protein 2). NPPB (N-terminal pro-BNP) was associated with HF in those with and without diabetes. Pathways over-represented among proteins associated with diabetes-related HF were lipid metabolism, inflammation, and brown adipose tissue (false discovery rate, q<0.05). CONCLUSIONS/UNASSIGNED:We identified 5 proteomic markers (4 novel) uniquely related to HF risk among individuals with diabetes and not among those without diabetes.

OBJECTIVE:Early-life exposure to phthalates, widely used in consumer products, may induce developmental lung adaptations and predispose to respiratory morbidity throughout childhood. We assessed the associations of fetal phthalate exposure with wheezing, asthma, and lung function from birth to adolescence. METHODS:We performed 1-stage individual participant data meta-analyses with data from six European birth cohorts (3,745 mother-child pairs) to assess associations of pregnancy-averaged maternal urinary concentrations of 7 phthalate metabolites and 3 phthalate groups (high- and low-molecular-weight phthalate metabolites and sum of di-2-ethylhexyl phthalate metabolites) with wheezing in infancy (0-1 years) and at preschool age (1-5 years), and asthma and lung function at school age (5-12 years). RESULTS:z-scores after multiple testing correction. CONCLUSION/CONCLUSIONS:Fetal exposure to higher phthalate concentrations is associated with lung function adaptations, while overall no consistent associations were observed with childhood wheezing or asthma. Future studies are needed to assess the causality of the observed associations, to identify the underlying mechanisms, and to assess potential respiratory consequences in adult life.

PURPOSE/OBJECTIVE:To examine factors associated with moving during pregnancy and impacts of assigning nSES at enrollment, delivery, or a time-weighted average on birth outcomes (birthweight, birthweight-for-gestational-age z-score, low birthweight, gestational age, small-for-gestational age, preterm birth). METHODS:We used data from the Environmental influences on Child Health Outcomes (ECHO) Cohort Study (2010-2019) with nSES data from the American Community Survey (ACS) matched by time and location to monthly residential histories. We used multivariable logistic models with Generalized Estimating Equations to identify factors associated with moving and quantify exposure misclassification in model estimates. RESULTS:Approximately 7% of 15,376 participants moved at least once during pregnancy. Maternal age (OR: 0.97, 95% CI: 0.95, 0.98) and other race vs. White (OR: 0.39, 95% CI: 0.20, 0.80) were associated with lower odds of moving; lower neighborhood-level education (OR: 1.34, 95% CI: 1.11, 1.62) and living in urban neighborhoods (OR: 3.03, 95% CI: 1.39, 6.59) were associated with higher odds. Among movers, estimates between nSES and birth outcomes changed ≥16% by address assignment; birthweight-for-gestational-age z-score was significant only when using nSES at delivery. CONCLUSION/CONCLUSIONS:Sociodemographic and nSES characteristics are associated with moving during pregnancy; movers may experience exposure misclassification and underestimated effects on birth outcomes.

Medical mistrust as a construct often places the onus of blame for adverse health outcomes on individuals rather than on social structures. In this study, we aimed to determine if medical mistreatment and access to transgender care were potential determinants of medical mistrust. We used longitudinal survey data from 193 transgender women of colour living in New York City. We measured medical mistrust using the Group-Based Medical Mistrust (GBMM) scale. Additionally, we analysed and coded open-ended survey data from participants regarding their trust towards medical institutions to identify potential determinants of medical mistrust. From the quantitative analysis, we found that individuals who experienced mistreatment in healthcare and those who reported poor access to transgender care had higher GBMM scores. Qualitative findings suggested that negative experiences within the healthcare system and historical trauma were key factors contributing to mistrust in medical institutions. Addressing medical mistrust should not occur at the individual level, but rather at the structural level. Potential interventions include improving access to gender affirming care and training health professionals.
