Appetite and adiposity in children: evidence for a behavioral susceptibility theory of obesity

BACKGROUND:Pressures from the "obesogenic" environment are driving up obesity rates, but adiposity still varies widely within the population. Appetitive characteristics could underlie differences in susceptibility to the environment. OBJECTIVE:We examined associations between adiposity and...

Description
Summary:BACKGROUND:Pressures from the "obesogenic" environment are driving up obesity rates, but adiposity still varies widely within the population. Appetitive characteristics could underlie differences in susceptibility to the environment. OBJECTIVE:We examined associations between adiposity and 2 appetitive traits: satiety responsiveness and food cue responsiveness in children. DESIGN:Parents of 2 groups of children, 8-11-y-olds (n = 10 364) from a population-based twin cohort and 3-5-y-olds (n = 572) from a community sample, completed the Child Eating Behavior Questionnaire. Adiposity was indexed with body mass index (BMI; in kg/m²) SD scores. For the 8-11-y-olds, waist circumference was also recorded and used to derive waist SD scores. RESULTS:In both samples, higher BMI SD scores were associated with lower satiety responsiveness (8-11-y-olds: r = -0.22; 3-5-y-olds: r = -0.19; P
