Heritability and genome-wide association analyses of sleep duration in children: The EAGLE Consortium.
2016
STUDY OBJECTIVES: Low or excessive sleep duration has been associated with multiple outcomes, but the biology behind these associations remains elusive. Specifically, genetic studies in children are scarce. In this study, we aimed to: (1) estimate the proportion of genetic variance of sleep duration in children attributed to common single nucleotide polymorphisms (SNPs), (2) identify novel SNPs associated with sleep duration in children, and (3) investigate the genetic overlap of sleep duration in children and related metabolic and psychiatric traits.METHODS: We performed a population-based molecular genetic study, using data form the EArly Genetics and Life course Epidemiology (EAGLE) Cons…
Maternal sleep duration and neonate birth weight: A population-based cohort study.
2021
Objective Sleep duration is an important health indicator. Our aim was to investigate the association between maternal sleep duration and infant birthweight. Methods The study included 2,536 mother-infant pairs of a Spanish birth cohort (2004-2006, INMA project). The exposures were questionnaire-based measures of sleep duration before and during pregnancy. The primary outcome was infant birthweight score (g) standardized to 40 weeks of gestation. Results In women sleeping less than 7 hours per day before pregnancy, each additional hour of sleep increased birthweight score by 44.7 g (p = 0.049) in the minimally-adjusted model, although findings were not statistically significant after consid…
