Household Food Insecurity and Maternal-Toddler Fruit and Vegetable Dietary Concordance
OBJECTIVE:To examine whether prenatal or concurrent household food insecurity influences associations between maternal and toddler fruit and vegetable (FV) intake. DESIGN/METHODS:Application of a life-course framework to an analysis of a longitudinal dataset. SETTING/METHODS:Early childhood obesity prevention program at a New York City public hospital. PARTICIPANTS/METHODS:One-hundred and fifty-six maternal-toddler dyads self-identifying as Hispanic or Latino. VARIABLES MEASURED/METHODS:Maternal and toddler FV intake was measured using Centers for Disease Control and Prevention dietary measures when toddlers were aged 19 months. Household food insecurity (measured prenatally and concurrently at 19 months) was measured using the US Department of Agriculture Food Security Module. ANALYSIS/METHODS:Regression analyses assessed associations between adequate maternal FV intake and toddler FV intake. Interaction terms tested whether prenatal or concurrent household food insecurity moderated this association. RESULTS:Adequate maternal FV intake was associated with increased toddler FV intake (B = 6.2 times/wk, 95% confidence interval, 2.0-10.5, P = 0.004). Prenatal household food insecurity was associated with decreased toddler FV intake (B = -6.3 times/wk, 95% confidence interval, -11.67 to -0.9, P = 0.02). There was a significant interaction between the level of maternal-toddler FV association (concordance or similarity in FV intake between mothers and toddlers) and the presence of food insecurity such that maternal-toddler FV association was greater when prenatal household food insecurity was not present (B = -11.6, P = 0.04). CONCLUSIONS AND IMPLICATIONS/CONCLUSIONS:Strategies to increase FV intake across the life course could examine how the timing of household food insecurity may affect intergenerational maternal-child transmission of dietary practices.

Prolonged Early Food Insecurity and Child Feeding Practices among a Low-Income Hispanic Population: Role of Parenting Stress
OBJECTIVE:To examine associations between prolonged early household food insecurity (FI) during pregnancy, infancy, and toddlerhood, and child feeding practices, and the mediating role of dysfunctional parent-child interactions. METHODS:We conducted secondary longitudinal analyses of data from the Starting Early Program (StEP) randomized controlled trial, which studied a primary care-based child obesity prevention program for low-income Hispanic families. Our independent variable was FI, using the USDA Food Security Module, during the third trimester of pregnancy and at child ages 10- and 19-months. Frequency of reported FI was defined by the number of periods with FI (0, 1, 2, or 3). Our dependent variables were feeding practices at child age 28-months using the Comprehensive Feeding Practices Questionnaire. Our mediating variable was dysfunctional parent-child interactions using the Parenting Stress Index subscale at age 19-months. We used linear regression to determine associations between frequency of reported FI and feeding practices adjusting for covariates, and mediation analyses to determine if dysfunctional parent-child interactions mediate these associations. RESULTS:Three hundred and forty four mothers completed assessments at child age 28-months. Of the 12 feeding practices examined, higher frequency of reported FI was positively associated with using food as a reward, restriction of food for weight control, and using food for emotional regulation, and was negatively associated with monitoring of less healthy foods. There was a significant indirect effect of frequency of reported FI on these practices through dysfunctional parent-child interactions. CONCLUSION/CONCLUSIONS:Higher frequency of reported FI was associated with four feeding practices, through dysfunctional parent-child interactions. Understanding these pathways can inform preventive interventions.

Prenatal Risks to Healthy Food Access and High Birthweight Outcomes
OBJECTIVE:Infants with high birthweight have increased risk for adverse outcomes at birth and across childhood. Prenatal risks to healthy food access may increase odds of high birthweight. We tested whether having a poor neighborhood food environment and/or food insecurity had associations with high birthweight. METHODS:We analyzed cross-sectional baseline data in Greenlight Plus, an obesity prevention trial across six US cities (n = 787), which included newborns with a gestational age greater than 34 weeks and a birthweight greater than 2500 g. We assessed neighborhood food environment using the Place-Based Survey and food insecurity using the US Household Food Security Module. We performed logistic regression analyses to assess the individual and additive effects of risk factors on high birthweight. We adjusted for potential confounders: infant sex, race, ethnicity, gestational age, birthing parent age, education, income, and study site. RESULTS:Thirty-four percent of birthing parents reported poor neighborhood food environment and/or food insecurity. Compared to those without food insecurity, food insecure families had greater odds of delivering an infant with high birthweight (adjusted odds ratios [aOR] 1.96, 95% confidence intervals [CI]: 1.01, 3.82) after adjusting for poor neighborhood food environment, which was not associated with high birthweight (aOR 1.35, 95% CI: 0.78, 2.34). Each additional risk to healthy food access was associated with a 56% (95% CI: 4%-132%) increase in high birthweight odds. CONCLUSIONS:Prenatal risks to healthy food access may increase high infant birthweight odds. Future studies designed to measure neighborhood factors should examine infant birthweight outcomes in the context of prenatal social determinants of health.

Researching COVID to enhance recovery (RECOVER) pediatric study protocol: Rationale, objectives and design
IMPORTANCE/OBJECTIVE:The prevalence, pathophysiology, and long-term outcomes of COVID-19 (post-acute sequelae of SARS-CoV-2 [PASC] or "Long COVID") in children and young adults remain unknown. Studies must address the urgent need to define PASC, its mechanisms, and potential treatment targets in children and young adults. OBSERVATIONS/METHODS:We describe the protocol for the Pediatric Observational Cohort Study of the NIH's REsearching COVID to Enhance Recovery (RECOVER) Initiative. RECOVER-Pediatrics is an observational meta-cohort study of caregiver-child pairs (birth through 17 years) and young adults (18 through 25 years), recruited from more than 100 sites across the US. This report focuses on two of four cohorts that comprise RECOVER-Pediatrics: 1) a de novo RECOVER prospective cohort of children and young adults with and without previous or current infection; and 2) an extant cohort derived from the Adolescent Brain Cognitive Development (ABCD) study (n = 10,000). The de novo cohort incorporates three tiers of data collection: 1) remote baseline assessments (Tier 1, n = 6000); 2) longitudinal follow-up for up to 4 years (Tier 2, n = 6000); and 3) a subset of participants, primarily the most severely affected by PASC, who will undergo deep phenotyping to explore PASC pathophysiology (Tier 3, n = 600). Youth enrolled in the ABCD study participate in Tier 1. The pediatric protocol was developed as a collaborative partnership of investigators, patients, researchers, clinicians, community partners, and federal partners, intentionally promoting inclusivity and diversity. The protocol is adaptive to facilitate responses to emerging science. CONCLUSIONS AND RELEVANCE/CONCLUSIONS:RECOVER-Pediatrics seeks to characterize the clinical course, underlying mechanisms, and long-term effects of PASC from birth through 25 years old. RECOVER-Pediatrics is designed to elucidate the epidemiology, four-year clinical course, and sociodemographic correlates of pediatric PASC. The data and biosamples will allow examination of mechanistic hypotheses and biomarkers, thus providing insights into potential therapeutic interventions.

Early Childcare Precarity and Subsequent Maternal Health
PURPOSE/OBJECTIVE:We examined prospective associations between early childcare precarity, or the security and reliability of childcare arrangements, and subsequent maternal health. STUDY DESIGN/METHODS:We conducted a secondary analysis of survey responses from mothers of 2,836 children in the Future of Families and Child Wellbeing study. We assessed the following childcare measures: insecure childcare, insecure childcare with missed work, inadequate childcare, and emergency childcare support. We used linear and logistic regression models with robust standard errors to examine associations between these measures when the index child was age 3 and maternal health outcomes (overall health, depression, and parenting stress) later when the child was age 9. We then examined additive experiences of childcare measures across child ages 1 and 3 on maternal health outcomes. RESULTS:Early inadequate childcare increased odds of later poor maternal overall health (adjusted odds ratio [aOR], 1.64; 95% confidence interval [CI], 1.11-2.41). All early childcare precarity measures increased odds of maternal depression (insecure childcare [aOR, 1.64; 95% CI, 1.23-2.18]; insecure childcare with missed work [aOR, 1.58; 95% CI, 1.13-2.22]; and inadequate childcare [aOR, 1.75; 95% CI, 1.22-2.51]). Emergency childcare support decreased the odds of adverse maternal health outcomes (poor overall health [aOR, 0.65; 95% CI, 0.48 to 0.88]; depression [aOR, 0.73; 95% CI, 0.54 to 0.99]; and parenting stress [B -0.45; 95% CI, -0.80 to -0.10]). Prolonged experiences had stronger associations with maternal health than shorter experiences. CONCLUSION/CONCLUSIONS:Early childcare precarity has long-term adverse associations with maternal health, and emergency childcare support seems to be favorable for maternal health. These findings highlight childcare precarity as a social determinant of women's health for researchers, clinicians, and decision-makers.

Social Capital and Sleep Outcomes Across Childhood in United States Families
OBJECTIVE:To examine whether aspects of social capital, or benefits received from social relationships, are associated with regular bedtime and sleep duration across childhood in US families with lower income. METHODS:Cross-sectional study using the 2018-19 National Survey of Children's Health in participants with incomes <400% federal poverty level. Separately for early childhood (0-5 years), school-age (6-12 years), and adolescence (13-17 years), we used weighted logistic regression to examine associations between social capital (measured by family social cohesion, parent social support, child social support) and sleep (measured by regular bedtime, sleep duration, adequate sleep per American of Academy of Sleep guidelines). Path analysis tested whether regular bedtime mediated associations between social capital and sleep duration. RESULTS:In our sample (N = 35,438), 84.9% had a regular bedtime, 60.2% had adequate sleep. Family social cohesion was associated with sleep duration and adequate sleep (infancy: adjusted odds ratio [aOR] 2.18 [95% confidence interval [CI], 1.32, 3.60]; school age: aOR 2.03 [95% CI, 1.57, 2.63]; adolescence: aOR 2.44 [95% CI, 1.94, 3.09]). In toddlerhood, parent social support was associated with adequate sleep (aOR 1.44 [95% CI, 1.06, 1.96]). In adolescence, child social support was associated with regular bedtime (aOR 1.70 [95% CI, 1.25, 2.32]. Across childhood, associations between family social cohesion and sleep duration were partially mediated by regular bedtime. CONCLUSIONS:Family social cohesion was associated with adequate sleep across childhood, this was partially mediated by regular bedtime. Associations between social support and sleep outcomes varied by development stage. Future work should consider how supportive relationships may influence child sleep outcomes.
