ObjectiveTo investigate whether short sleep duration from the first year of life influenced weight at an early age.Study designDuring 2004, children born in Pelotas, Brazil, were enrolled in a cohort study. Sleeping habits during the previous 2Â weeks were assessed, and the children were weighed and measured at 1-, 2-, and 4-year follow-ups. Overweight and obesity at 4Â years were defined according to World Health Organization z-scores for body mass index for age. Short sleep duration was defined as fewer than 10Â hours of sleep per night at any follow-up.ResultsOut of the 4263 live births, 4231 were recruited. The prevalence of short sleep duration at any follow-up from 1-4Â years of age was 10.1%. At 4Â years of age, 201 children were obese (5.3%), and 302 (8%) were overweight. Among short sleepers, the prevalence ratio for overweight/obesity after adjusting for maternal and children's characteristics was 1.32 (1.03; 1.70).ConclusionsChildren who slept for fewer than 10Â hours per night at any follow-up from 1-4Â years of age were more likely to be overweight or obese at 4Â years of age, despite their sociodemographic and sleep characteristics.
