Executive function and latent classes of childhood obesity risk.

Executive function (EF) is the set of neuro-cognitive processes associated with self-regulation, decision-making, and goal-directed behavior. The goal of this study is to examine cross-sectional relationships between EF and latent classes of youth characterized by patterns of obesity-related health behaviors (i.e., high fat/high sugar intake, fruit and vegetable intake, physical activity, sedentary behavior, and dieting). Participants were 997 4th grade youth in a school-based obesity prevention program. Cross-sectional relationships at study baseline between established latent classes of obesity risk and EF problems were assessed. General linear models demonstrated that EF problems were associated with classification into two unhealthy latent obesity risk classes. One potential implication of study findings is that obesity intervention efforts include EF promotion content tailored for latent classes of youth at different levels of obesity risk.
