Trait impulsivity and body mass index [0.84 mb]
Abstract (English)

Impulsivity has been suggested to be associated with obesity. However, findings are fairly inconsistent and it appears that only specific facets of impulsivity are related to overeating and body mass. In this study, relationships between scores on a short form of the Barratt Impulsiveness Scale and body mass index were examined in a heterogeneous sample (N = 3073). After controlling for age and sex, only scores on attentional and motor impulsivity, but not non-planning impulsivity, were predictive of higher body mass index. The magnitude of these relationships, however, was very small. Thus, future research needs to address possible mediators and moderators of the relationship between impulsivity and body mass in order to explain why only specific facets of impulsivity appear to play a role in obesity and under which circumstances heightened impulsivity levels are associated with higher body weight.
