Fetal bisphenol and phthalate exposure and early childhood growth in a New York City birth cohort.

BACKGROUND: Exposure to endocrine-disrupting chemicals such as bisphenols and phthalates during pregnancy may disrupt fetal developmental programming and influence early-life growth. We hypothesized that prenatal bisphenol and phthalate exposure was associated with alterations in adiposity through 4 years. This associations might change over time. METHODS: Among 1091 mother-child pairs in a New York City birth cohort study, we measured maternal urinary concentrations of bisphenols and phthalates at three time points in pregnancy and child weight, height, and triceps and subscapular skinfold thickness at ages 1, 2, 3, and 4 years. We used linear mixed models to assess associations of prenatal individual and grouped bisphenols and phthalates with overall and time-point-specific adiposity outcomes from birth to 4 years. RESULTS: We observed associations of higher maternal urinary second trimester total bisphenol and bisphenol A concentrations in pregnancy and overall child weight between birth and 4 years only (Beta 0.10 (95 % confidence interval 0.04, 0.16) and 0.07 (0.02, 0.12) standard deviation score (SDS) change in weight per natural log increase in exposure), We reported an interaction of the exposures with time, and analysis showed associations of higher pregnancy-averaged mono-(2-carboxymethyl) phthalate with higher child weight at 3 years (0.14 (0.06, 0.22)), and of higher high-molecular-weight phthalate, di-2-ethylhexyl phthalate, mono-(2-ethyl-5-carboxypentyl) phthalate, mono-(2-carboxymethyl) phthalate, and mono-(2-ethylhexyl) phthalate with higher child weight at 4 years (0.16 (0.04, 0.28), 0.15 (0.03, 0.27), 0.19 (0.07, 0.31), 0.16 (0.07, 0.24), 0.11 (0.03, 0.19)). Higher pregnancy-averaged high-molecular-weight phthalate, di-2-ethylhexyl phthalate, mono-(2-ethyl-5-carboxypentyl) phthalate, mono-(2-ethyl-5-hydroxyhexyl) phthalate, and mono-2(ethyl-5-oxohexyl) phthalate concentrations were associated with higher child BMI at 4 years (0.20 (0.05, 0.35), 0.20 (0.05, 0.35), 0.22 (0.06, 0.37), 0.20 (0.05, 0.34), 0.20 (0.05, 0.34)). For skinfold thicknesses, we observed no associations. DISCUSSION: This study contributes to the evidence suggesting associations of prenatal exposure to bisphenols and high-molecular-weight phthalates on childhood weight and BMI.

Prenatal and Pediatric Primary Care-Based Child Obesity Prevention: Effects of Adverse Social Determinants of Health on Intervention Attendance and Impact.

Background: Adverse social determinants of health (SDoHs), specifically psychosocial stressors and material hardships, are associated with early childhood obesity. Less is known about whether adverse SDoHs modify the efficacy of early childhood obesity prevention programs. Methods: We conducted a secondary analysis of publicly insured birthing parent-child dyads with Latino backgrounds participating in a randomized controlled trial of the Starting Early Program (StEP), a child obesity prevention program beginning in pregnancy. We measured baseline adverse SDoHs categorized as psychosocial stressors (low social support, single marital status, and maternal depressive symptoms) and material hardships (food insecurity, housing disrepair, and financial difficulties) individually and cumulatively in the third trimester. Logistic regression models tested effects of adverse SDoHs on StEP attendance. We then tested whether adverse SDoHs moderated intervention impacts on weight at age 2 years. Results: We observed heterogeneous effects of adverse SDoHs on outcomes in 358 parent-child dyads. While housing disrepair decreased odds of higher attendance [adjusted odds ratio (aOR) 0.52, 95% confidence interval (CI): 0.29-0.94], high levels of psychosocial stressors doubled odds of higher attendance (aOR 2.36, 95% CI: 1.04-5.34). Similarly, while certain adverse SDoHs diminished StEP impact on weight (e.g., housing disrepair), others (e.g., high psychosocial stress) enhanced StEP impact on weight. Conclusions: Effects of adverse SDoHs on intervention outcomes depend on the specific adverse SDoH. Highest engagement and benefit occurred in those with high psychosocial stress at baseline, suggesting that StEP components may mitigate aspects of psychosocial stressors. Findings also support integration of adverse SDoH assessment into strategies to enhance obesity prevention impacts on families with material hardships. Trial Registration: This study is registered on clinicaltrials.gov: Starting Early Obesity Prevention Program (NCT01541761); https://clinicaltrials.gov/ct2/show/NCT01541761.

Early Childcare Precarity and Subsequent Maternal Health.

PURPOSE: We examined prospective associations between early childcare precarity, or the security and reliability of childcare arrangements, and subsequent maternal health. STUDY DESIGN: 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 was associated with higher 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 were associated with higher 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 was associated with lower 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: 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.

Material Hardship, Protective Factors, Children's Special Health Care Needs, and the Health of Mothers and Fathers.

BACKGROUND: Parents of children with special health care needs (CSHCN) are at risk of poorer health outcomes. Material hardships also pose significant health risks to parents. Little is known about how protective factors may mitigate these risks and if effects are similar between mothers and fathers. METHODS: This was a cross-sectional survey study conducted using the US 2018/2019 National Survey of Children's Health, including parents of children 0 to 17 with income <200% of the federal poverty level. Separately, for parents of children with and without special health care needs (N-CSHCN), weighted logistic regression measured associations between material hardship, protective factors (family resilience, neighborhood cohesion, and receipt of family-centered care), and 2 outcomes: mental and physical health of mothers and fathers. Interactions were assessed between special health care needs status, material hardship, and protective factors. RESULTS: Sample consisted of parents of 16,777 children; 4440 were parents of CSHCN. Most outcomes showed similar associations for both mothers and fathers of CSHCN and N-CSHCN: material hardship was associated with poorer health outcomes, and family resilience and neighborhood cohesion associated with better parental health outcomes. Family-centered care was associated with better health of mothers but not fathers. Interaction testing showed that the protective effects of family resilience were lower among fathers of CSHCN experiencing material hardship. CONCLUSIONS: Family resilience and neighborhood cohesion are associated with better health outcomes for all parents, though these effects may vary by experience of special health care needs, parent gender, and material hardship.

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: Application of a life-course framework to an analysis of a longitudinal dataset. SETTING: Early childhood obesity prevention program at a New York City public hospital. PARTICIPANTS: One-hundred and fifty-six maternal-toddler dyads self-identifying as Hispanic or Latino. VARIABLES MEASURED: 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: 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: 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.

Supporting early childhood routines to promote cardiovascular health across the life course.

Optimal cardiovascular health is an essential component of human health and well-being across the life course. Heart healthy practices around diet, physical activity, and sleep early in childhood have the potential to greatly improve lifespan and quality (Mehta et al., 2020). Early childhood routines, defined as functional practices that are predictable and repeatable, predict positive growth and development across the lifecourse (Fiese et al., 2002; Ferretti and Bub, 2017; Spagnola and Fiese, 2007). The American Heart Association has identified key heart healthy routines, such as daily regular activities including diet, physical activity, and sleep that promote cardiovascular health (Lloyd-Jones et al., 2022). Integrating the strength-based relational aspects of routines with the acquisition of cardiovascular health development capabilities allows children to establish their own optimal cardiovascular health trajectory early on. A systematic life course approach to supporting heart healthy routines in early childhood would inform clinical, research, and policy strategies to promote long-term cardiovascular health, and contribute to reducing inequalities in cardiovascular outcomes.

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.

The regulation of endocrine-disrupting chemicals to minimize their impact on health.

Endocrine-disrupting chemicals (EDCs) are substances generated by human industrial activities that are detrimental to human health through their effects on the endocrine system. The global societal and economic burden posed by EDCs is substantial. Poorly defined or unenforced policies can increase human exposure to EDCs, thereby contributing to human disease, disability and economic damage. Researchers have shown that policies and interventions implemented at both individual and government levels have the potential to reduce exposure to EDCs. This Review describes a set of evidence-based policy actions to manage, minimize or even eliminate the widespread use of these chemicals and better protect human health and society. A number of specific challenges exist: defining, identifying and prioritizing EDCs; considering the non-linear or non-monotonic properties of EDCs; accounting for EDC exposure effects that are latent and do not appear until later in life; and updating testing paradigms to reflect 'real-world' mixtures of chemicals and cumulative exposure. A sound strategy also requires partnering with health-care providers to integrate strategies to prevent EDC exposure in clinical care. Critical next steps include addressing EDCs within global policy frameworks by integrating EDC exposure prevention into emerging climate policy.

Prenatal oxidative stress and rapid infant weight gain.

BACKGROUND AND OBJECTIVES: Infant weight patterns predict subsequent weight outcomes. Rapid infant weight gain, defined as a >0.67 increase in weight-for-age z-score (WAZ) between two time points in infancy, increases obesity risk. Higher oxidative stress, an imbalance between antioxidants and reactive oxygen species, has been associated with low birthweight and paradoxically also with later obesity. We hypothesized that prenatal oxidative stress may also be associated with rapid infant weight gain, an early weight pattern associated with future obesity. METHODS: Within the NYU Children's Health and Environment Study prospective pregnancy cohort, we analyzed associations between prenatal lipid, protein, and DNA urinary oxidative stress biomarkers and infant weight data. Primary outcome was rapid infant weight gain (>0.67 increase in WAZ) between birth and later infancy at the 8 or 12 month visit. Secondary outcomes included: very rapid weight gain (>1.34 increase in WAZ), low (<2500 g) or high (≥4000 g) birthweight, and low (< -1 WAZ) or high (>1 WAZ) 12 month weight. RESULTS: Pregnant participants consented to the postnatal study (n = 541); 425 participants had weight data both at birth and in later infancy. In an adjusted binary model, prenatal 8-iso-PGF2α, a lipid oxidative stress biomarker, was associated with rapid infant weight gain (aOR 1.44; 95% CI: 1.16, 1.78, p = 0.001). In a multinomial model using ≤0.67 change in WAZ as a reference group, 8-iso-PGF2α was associated with rapid infant weight gain (defined as >0.67 but ≤1.34 WAZ; aOR 1.57, 95% CI: 1.19, 2.05, p = 0.001) and very rapid infant weight gain (defined as >1.34 WAZ; aOR 1.33; 95% CI: 1.02, 1.72, p < 0.05) Secondary analyses detected associations between 8-iso-PGF2α and low birthweight outcomes. CONCLUSIONS: We found an association between 8-iso-PGF2α, a lipid prenatal oxidative stress biomarker, and rapid infant weight gain, expanding our understanding of the developmental origins of obesity and cardiometabolic disease.

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.

Infant Feeding Practices and Social Support Networks Among Immigrant Chinese American Mothers With Economic Disadvantage in New York City.

BACKGROUND: Maternal social support promotes healthy infant feeding practices, which influence healthy growth and development. Less is known about how the interplay of social support networks and multicultural health beliefs may influence infant feeding practices, particularly among immigrant Chinese American mothers with economic disadvantage and low breastfeeding rates. RESEARCH AIM: To explore the role of social support networks in the development of infant feeding practices in immigrant Chinese American mothers with infants. METHODS: This was a prospective, cross-sectional qualitative study where we conducted semi-structured interviews in Mandarin, Cantonese, or English with Chinese American mothers of infants (N = 25) at a federally qualified health center in the Sunset Park neighborhood of Brooklyn, New York. Data were analyzed by a multicultural, multidisciplinary team using qualitative thematic analysis and the constant comparative method to identify and iteratively refine emerging codes. RESULTS: Three themes emerged describing how broad transnational communities and close family and friends influence maternal-infant feeding practices: (1) Gathering and processing infant feeding information from broad transnational resources (i.e., from both the mother's country of residence and the mother's country of origin); (2) aligning maternal feeding attitudes with cultural health beliefs of local social networks; and (3) gaining confidence with transactional maternal-infant feeding interactions. CONCLUSIONS: Strategies to promote healthy infant feeding should consider how family supports and culturally-relevant coaching can help align multilevel transnational social networks with healthy infant feeding practices.

Modified body mass index z-scores in children in New York City during the COVID-19 pandemic.

OBJECTIVES: Determine whether the negative impact of the COVID-19 pandemic on weight gain trajectories among children attending well-child visits in New York City persisted after the public health restrictions were reduced. STUDY DESIGN: Multicenter retrospective chart review study of 7150 children aged 3-19 years seen for well-child care between 1 January 2018 and 4 December 2021 in the NYC Health and Hospitals system. Primary outcome was the difference in annual change of modified body mass index z-score (mBMIz) between the pre-pandemic and early- and late-pandemic periods. The mBMIz allows for tracking of a greater range of BMI values than the traditional BMI z-score. The secondary outcome was odds of overweight, obesity, or severe obesity. Multivariable analyses were conducted with each outcome as the dependent variable, and year, age category, sex, race/ethnicity, insurance status, NYC borough, and baseline weight category as independent variables. RESULTS: The difference in annual mBMIz change for pre-pandemic to early-pandemic = 0.18 (95% confidence interval [CI]: 0.15, 0.20) and for pre-pandemic to late-pandemic = 0.04 (95% CI: 0.01, 0.06). There was a statistically significant interaction between period and baseline weight category. Those with severe obesity at baseline had the greatest mBMIz increase during both pandemic periods and those with underweight at baseline had the lowest mBMIz increase during both pandemic periods. CONCLUSION: In NYC, the worsening mBMIz trajectories for children associated with COVID-19 restrictions did not reverse by 2021. Decisions about continuing restrictions, such as school closures, should carefully weigh the negative health impact of these policies.

The Prenatal Neighborhood Environment and Geographic Hotspots of Infants with At-risk Birthweights in New York City.

Infants born with low or high ("at-risk") birthweights are at greater risk of adverse health outcomes across the life course. Our objective was to examine whether geographic hotspots of low and high birthweight prevalence in New York City had different patterns of neighborhood risk factors. We performed census tract-level geospatial clustering analyses using (1) birthweight prevalence and maternal residential address from an all-payer claims database and (2) domains of neighborhood risk factors (socioeconomic and food environment) from national and local datasets. We then used logistic regression analysis to identify specific neighborhood risk factors associated with low and high birthweight hotspots. This study examined 2088 census tracts representing 419,025 infants. We found almost no overlap (1.5%) between low and high birthweight hotspots. The majority of low birthweight hotspots (87.2%) overlapped with a socioeconomic risk factor and 95.7% overlapped with a food environment risk factor. Half of high birthweight hotspots (50.0%) overlapped with a socioeconomic risk factor and 48.8% overlapped with a food environment risk factor. Low birthweight hotspots were associated with high prevalence of excessive housing cost, unemployment, and poor food environment. High birthweight hotspots were associated with high prevalence of uninsured persons and convenience stores. Programs and policies that aim to prevent disparities in infant birthweight should examine the broader context by which hotspots of at-risk birthweight overlap with neighborhood risk factors. Multi-level strategies that include the neighborhood context are needed to address prenatal pathways leading to low and high birthweight outcomes.

Material Hardship and Stress from COVID-19 in Immigrant Chinese American Families with Infants.

Material hardship and stress, associated with poor infant outcomes, increased during the Coronavirus Disease 2019 pandemic. Chinese American families were vulnerable to racism-driven disparities. Little is known about maternal perceptions of pandemic impacts on their infants, family, and community. Purposive sampling of low-income Chinese American mothers (n = 25) with infants (1-15 months). Semi-structured qualitative interviews conducted in Mandarin, Cantonese, or English were audio-recorded, transcribed, and translated. Transcripts coded using applied thematic analysis in an iterative process of textual analysis until thematic saturation. Three themes emerged: (1) Heightened family hardship included financial strain, disruption of transnational childcare, experiences of racism; (2) Altered infant routines/developmental consequences included using protective equipment on infants, concerns about infant socio-emotional development; (3) Coping strategies included stockpiling essentials, adapting family diets. Strategies to mitigate disparities include expanding social needs screening, correcting misinformation, strengthening support networks, and including low-income Chinese Americans in these efforts.

Duration of US Residence And Resource Needs In Immigrant Families With Young Children.

To mitigate the negative impact of resource needs on child health, practices serving low-income immigrant families have implemented screening programs to connect families to community resources. Little is known about how duration of US residence relates to patterns of resource needs and indicators of acculturation such as community resource knowledge/experience or self-efficacy. We conducted a cross-sectional analysis of a convenience sample of immigrant families with young children at an urban primary care clinic. These families were seen 5/2018-1/2020 for well child care, screening positive for ≥1 social need using a tool derived from Health Leads. Analysis of 114 families found that newly arrived families with a shorter duration of US residence (≤5 years) were more likely to report immediate material hardships like food insecurity and need for essential child supplies. Newly arrived families were also less likely to have access to technology resources such as a computer or smartphone. Long-term families with a longer duration of US residence (≥15 years) were more likely to report chronic needs like poor housing conditions, but also reported increased community resource knowledge/experience and increased self-efficacy. Primary care pediatric practices should assess immigration contextual factors to identify subgroups such as newly arrived families with young children to target resources (e.g., increase screening frequency) or enhance services (e.g., patient navigators) to relieve resource needs.

Social Capital as a Positive Social Determinant of Health: A Narrative Review.

Social determinants of health influence child health behavior, development, and outcomes. This paper frames social capital, or the benefits that a child receives from social relationships, as a positive social determinant of health that helps children exposed to adversity achieve healthy outcomes across the life course. Children are uniquely dependent on their relationships with surrounding adults for material and nonmaterial resources. We identify and define three relevant aspects of social capital: 1) social support, which is embedded in a 2) social network, which is a structure through which 3) social cohesion can be observed. Social support is direct assistance available through social relationships and can be received indirectly through a caregiver or directly by a child. A child's social network describes the people in a child's life and the relationships between them. Social cohesion represents the strength of a group to which a child belongs (eg, family, community). Pediatric primary care practices play an important role in fostering social relationships between families, the health care system, and the community. Further research is needed to develop definitional and measurement rigor for social capital, to evaluate interventions (eg, peer health educators) that may improve health outcomes through social capital, and to broaden our understanding of how social relationships influence health outcomes.

Material Hardships and Infant and Toddler Sleep Duration in Low-Income Hispanic Families.

OBJECTIVE: To assess relationships between material hardships, shortened sleep duration, and suboptimal sleep practices across infancy and toddlerhood in low-income Hispanic families. METHODS: We analyzed longitudinal data of 451 low-income Hispanic mother-child pairs from a child obesity prevention trial. During infancy and toddlerhood, we used adjusted linear regression to assess associations between material hardship (financial difficulty, food insecurity, housing disrepair, and multiple hardships), sleep duration (24-hour, night), and the number of suboptimal sleep practices (eg, later bedtime, co-sleeping). We used adjusted linear regression to assess the longitudinal association between the number of suboptimal sleep practices in infancy and toddlerhood, and tested whether specific or multiple hardships moderated this association. RESULTS: In infants, financial difficulty and multiple hardships were associated with decreased night sleep (B = -0.59 hours, 95% confidence interval [CI]: -1.04, -0.14; and B = -0.54 hours, 95% CI: -1.00, -0.08). Housing disrepair was associated with decreased 24-hour sleep (B = -0.64 hours, 95% CI: -1.29, -0.01). In toddlers, each additional suboptimal sleep practice was associated with a decrease in night sleep (B = -0.19 hours, 95% CI: -0.29, -0.09). Each additional suboptimal sleep practice in infancy was associated with a 0.30 increase in the number of suboptimal sleep practices in toddlerhood (P < .001), with greater increases for those with food insecurity or multiple hardships. CONCLUSION: Specific and multiple hardships shortened sleep duration during infancy, and moderated the increase of suboptimal sleep behaviors between infancy and toddlerhood. Future studies should consider these early critically sensitive periods for interventions to mitigate material hardships and establish healthy sleep practices.

Implementation of Febrile Infant Management Guidelines Reduces Hospitalization.

The clinical management of well-appearing febrile infants 7-60 days of age remains variable due in part to multiple criteria differentiating the risk of a serious bacterial infection. The purpose of this quality improvement study was to standardize risk stratification in the emergency department and length of stay in the inpatient unit by implementing an evidence-based clinical practice guideline (CPG). METHODS: The Model for Improvement was used to implement a CPG for the management of well-appearing febrile infants, with collaboration between pediatric emergency medicine and pediatric hospital medicine physicians. Interventions included physician education, process audit/feedback, and development of an electronic orderset. We used statistical process control charts to assess the primary aims of appropriate risk stratification and length of stay. RESULTS: Over a 34-month period, 168 unique encounters (baseline n = 65, intervention n = 103) were included. There was strong adherence for appropriate risk stratification in both periods: the proportion of low-risk patients admitted inappropriately decreased from 14.8% to 10.8%. Among admitted high-risk patients, the mean length of stay decreased from 49.4 to 38.2 hours, sustained for 18 months. CONCLUSION: CPG implementation using quality improvement methodology can increase the delivery of evidence-based care for febrile infants, leading to a reduction in length of stay for high-risk infants.

Associations Between Family and Community Protective Factors and Attention-Deficit/Hyperactivity Disorder Outcomes Among US Children.

BACKGROUND: Evidence has established the association between risk factors and attention-deficit/hyperactivity disorder (ADHD) severity, but less is known about factors that may have protective effects on clinical, academic, and social outcomes among children with ADHD. OBJECTIVE: To examine associations between family cohesion, caregiver social support, community support, and (1) ADHD severity, (2) school engagement, and (3) difficulty making or keeping friends. METHODS: Cross-sectional study of school-aged and adolescent children with ADHD using data from the 2016 National Survey of Children's Health. Our outcomes were (1) parent-rated ADHD severity, (2) school engagement, and (3) difficulty making or keeping friends. Our independent variables were (1) family cohesion, (2) caregiver social support, and (3) community support. We used logistic regression models to examine associations between our independent variables and each of our outcome variables, adjusting for child and parent sociodemographic characteristics. RESULTS: In our sample (N = 4,122, weighted N = 4,734,322), children exposed to family cohesion and community support had lower odds of moderate to severe ADHD [adjusted OR (aOR): 0.73 (0.55-0.97); aOR: 0.73 (0.56-0.95), respectively], higher odds of school engagement [aOR: 1.72, (1.25-2.37); aOR: 1.38, (1.04-1.84), respectively], and lower odds of difficulty making or keeping friends [aOR: 0.64, (0.48-0.85); aOR: 0.52, (0.40-0.67), respectively]. CONCLUSION: Among children with ADHD, family cohesion and community support show protective effects in clinical, academic, and social outcomes. Systematically identifying family- and community-level strengths may be important components of multimodal treatment strategies in children with ADHD.
