Abstract
Objectives: To determine in children aged 0-7 years (1) cross-sectional relationships between body mass index (BMI) and sleep duration, and whether (2) sleep duration predicts later BMI and/or (3) BMI predicts later sleep duration. Design: Longitudinal Study of Australian Children, Waves 1 and 2. Participants: Infants aged 0-1 years (Wave 1), followed at age 2-3 years (Wave 2); children aged 4-5 years (Wave 1), followed at age 6-7 years (Wave 2). Main outcome measures: BMI, sleep duration by time-use diary, parent-reported sleep problems (none/mild vs moderate/severe). Analyses: Cross-sectional, ANOVA (sleep duration) and χ2 (sleep problems); longitudinal, linear regression. Results: 3857 (7..
