BackgroundBody weight in childhood may predict appetitive traits. However, studies on the accumulated effect of adiposity and approaches using the clustering of different appetitive traits are lacking.ObjectiveTo test associations between a cumulative measure of adiposity [from 4 to 13 years old (y)] and appetitive trait trajectory profiles (from 7 to 13 y), as well as to explore whether body mass index (BMI) at specific ages is associated with these profiles, independently of the cumulative BMI.MethodsParticipants are from the Generation XXI birth cohort (Porto, Portugal) with weight and height measured at 4, 7, 10 and 13 y and complete data in variables of interest (final sample of n = 3339). Age- and sex-specific adjusted BMI standard deviation scores were calculated. The duration and degree of BMI were summarized through the BMI area under the curve (BMIAUC), as an indicator of accumulated adiposity. Appetitive traits were assessed at 7, 10 and 13 y, using the validated Children's Eating Behaviour Questionnaire. Six previously identified profiles of appetite (groups of individuals with similar patterns of trajectories) were considered: 'moderate appetite' (reference profile), 'small appetite but increasing', 'small to moderate appetite', 'avid appetite', 'increasing appetite' and 'smallest appetite'. Multinomial logistic regressions tested associations between BMIAUC and profiles.ResultsThe median monthly exposure to BMIAUC was 17.4 kg/m2. Except for 'increasing appetite', BMIAUC was associated with all profiles: positively with the 'avid appetite' (OR = 1.47, 95% CI: 1.40-1.55) and negatively with the remaining ones, particularly with 'smallest appetite' (OR = 0.78, 95% CI: 0.73-0.83). Having overweight/obesity at 7 y increased 113% the odds of having an 'avid appetite' profile (OR = 2.13 95% CI: 1.42-3.21).ConclusionChildren with the highest cumulative adiposity between 4 and 13 y were more likely to present an 'avid appetite' during childhood. Additionally, having excessive weight at age 7 may indicate a higher appetite in subsequent years.
