Objective: To determine the extent to which weight gain and eating behaviours in infancy predict later adiposity. Design: Population-based, prospective, longitudinal birth cohort study. Weights collected in infancy were used to calculate Z-scores for weight gain to age 1 year conditional on birth weight (CWG). To avoid multiple significance tests, variables from the parent questionnaire completed at age 1 year describing eating avidity were combined using general linear modelling to create an infancy avidity score. Anthropometry, skinfold thicknesses and bioelectrical impedance data collected at age 7-8 years were combined using factor analysis, to create an adiposity index. Setting: Gateshead, UK. Subjects: Members of the Gateshead Millennium Study cohort with data at both time points (n 561). Results: CWG in infancy significantly predicted adiposity at age 7 years, but related more strongly to length and lean mass. High adiposity (> 90th internal percentile) at age 7 years was significantly associated with high CWG (relative risk 2.76; 95% CI 1.5, 5.1) in infancy, but less so with raised (> 74th internal percentile) eating avidity in infancy (relative risk 1.87; 95% CI 0.9, 3.7). However, the majority of children with high weight gain (77.6%) or avidity (85.5%) in infancy did not go on to have high adiposity at age 7 years. Conclusions: Rapid weight gain in infancy and the eating behaviours which relate to it do predict later adiposity, but are more strongly predictive of later stature and lean mass.
