Objective : To use an ecological systems approach to examine individual-family-community-and area-level risk factors for overweight (including obesity) in 3-year-old children. Methods : A prospective nationally representative cohort study conducted in England, Wales, Scotland, Northern Ireland. Participants included 13 188 singleton children aged 3 years in the Millennium Cohort Study, born between 2000 and 2002, who had complete height/weight data. The main outcome measure was childhood overweight (including obesity) defined by the International Obesity TaskForce cut-offs for body mass index. Results : 23.0% of 3-year-old children were overweight or obese. In the fully adjusted model, primarily individual-and family-level factors were associated with early childhood overweight : birthweight z-score (adjusted odds ratio, 1.36,95% Cl 1.30 to 1.42), black ethnicity (1.41,1.11 to 1.80) (compared with white), introduction to solid foods=21 hours/week (1.23,1.10 to 1.37) (compared with never worked). Breastfeeding>=4 months (0.86,0.76 to 0.97) (compared with none) and Indian ethnicity (0.63,0.42 to 0.94) were associated with a decreased risk of early childhood overweight. Children from Wales were also more likely to be overweight than children from England. Conclusions : Most risk factors for early childhood overweight are modifiable or would allow at-risk groups to be identified. Policies and interventions should focus on parents and providing them with an environment to support healthy behaviours for themselves and their children.
