Mattsson M, Murray DM, Kiely M, et al. - In this cross-sectional study, researchers sought to identify behavioural clusters of 5-year-old children based on lifestyle behaviours, and to explore potential determinants of class membership, as well as to determine if class membership was correlated with body measure outcomes at 5 years of age. Information on eating behaviour, engagement in active play, TV watching, and sleep duration in 1,229 5-year-old children from the Cork BASELINE birth cohort study were collected through in-person interviews with parent. Using a large prospective birth cohort in Ireland, the authors identified three latent classes based on eating behaviour, activity, and sleep in children aged 5 years. Children with high food approach scores who also had lower levels of activity and sleep duration were at a higher risk of being overweight or obese.
