Short Sleep Duration and Later Overweight in Infants

Objective To provide further knowledge about the longitudinal association between sleep duration and overweight in infants. Study design The data for this study are from the CHILD-SLEEP birth cohort (n = 1679). The sleep data are based on parent-reported total sleep duration collected at 3, 8, 18, and 24 months. For a subgroup of 8-month old participants (n = 350), an actigraph recording was also made. Growth data were derived from the child health clinic records. A logistic regression model was used to study the association between sleep duration and later weight development. Results Shorter sleep duration in 3-month-old infants was cross-sectionally associated with lower weight-for-length/height (all P values Conclusions Short total sleep duration at the age of 3 months and short night-time sleep duration at the age of 8 months are associated with the risk of gaining excess weight at 24 months of age.Peer reviewe
