Maternal nutrition during gestation has been investigated for its role in child neurodevelopment. However, little is known about the potential impact of gestational caffeine exposure on child autistic behaviors. Here, we assess the relation between maternal caffeine intake during pregnancy and children's behavioral traits related to Autism Spectrum Disorder (ASD). We harmonized data from two pregnancy cohorts, Early Autism Risk Longitudinal Investigation (EARLI) (n = 120), an enriched-risk cohort of mothers who previously had a child with ASD, from Pennsylvania, Maryland, and Northern California (2009–2012), and the Health Outcomes and Measures of the Environment (HOME) Study (n = 269), a general population cohort from Cincinnati, Ohio (2003–2006). Mothers self-reported caffeine intake twice during pregnancy. Caregivers reported child behavioral traits related to ASD using the Social Responsiveness Scale (SRS) when children were aged 3–8 years. Higher scores indicate more ASD-related behaviors. We estimated covariate-adjusted differences in continuous SRS T-scores per interquartile range increase in caffeine intake. Self-reported caffeine intake during pregnancy was positively associated with SRS T-scores among children in EARLI (β: 2.0; 95% CI -0.1, 4.0), but to a lesser extent in HOME (β: 0.6; 95% CI -0.5, 1.6). In HOME, pre-pregnancy body mass index (BMI) modified the association between caffeine intake and SRS T-scores, where more positive associations were observed among women with higher BMIs. Our findings suggest gestational caffeine intake may represent a marker of vulnerability to childhood ASD-related behaviors. Additional studies are warranted to extend these findings.

Examines the combined use of maternal antenatal corticosteriods and antibiotic therapy in Cincinnati, Ohio. Increase in the risk of late-onset neonatal sepsis in the very low birth weight infant; Use of chi-square test; Application of univariate analysis.

OBJECTIVE. The goal was to test the hypothesis that participation in a community-based home-visiting program is associated with a decreased risk of infant death. METHODS. A retrospective, case-control design was used to compare the risk of infant death among participants in Cincinnati's Every Child Succeeds program and control subjects matched for gestational age at birth, previous pregnancy loss, marital status, and maternal age. The likelihood of infant death, adjusted for level of prenatal care, maternal smoking, maternal education, race, and age, was determined with multivariate logistic regression. The interaction between race and program participation and the effect of home visiting on the risk of preterm birth were explored. RESULTS. Infants whose families did not receive home visiting (n = 4995) were 2.5 times more likely to die in infancy compared with infants whose families received home visiting (n = 1665). Black infants were at least as likely to benefit from home visiting as were nonblack infants. No effect of program participation on the risk of preterm birth was observed. CONCLUSION. The current study is consistent with the hypothesis that intensive home visiting reduces the risk of infant death. [ABSTRACT FROM AUTHOR]
