Abstract
Objective
To investigate the association between eating traits (e.g. dietary restraint or opportunistic eating) and weight – both cross‐sectionally and longitudinally – and whether physical activity (PA) moderates these associations.
Methods
Two‐hundred seventy young adults (21–35 years; BMI: 25.40 kg/m2 [SD = 3.90 kg/m2]; 48.90% female) participated in this 12‐month observational cohort study. Cognitive Restraint (CR), Disinhibition (DI) and Hunger (HU) were measured using the Three‐Factor Eating Questionnaire at baseline and 12 months. Participants were measured at quarterly intervals for objectively measured PA and anthropometrics. Cross‐sectional and longitudinal models determined if eating traits were associated with weight or weight change, and whether these associations were moderated by PA.
Results
At baseline, higher CR (B = 0.429, p < 0.01) and DI (B = 0.942, p < 0.01) were associated with higher weight. The associations of DI (B = −0.008 p = 0.02) and HU (B = −0.006, p = 0.04) with weight were moderated by PA at baseline. The longitudinal model for CR determined PA altered the relationship between change in CR and weight change (B = 0.004, p < 0.01).
Conclusions
Eating traits and PA are associated with weight and weight change. However, to elucidate how PA and eating traits directly affect weight changes, future weight loss interventions should investigate whether improving eating traits and concomitantly increasing PA amplify weight loss.
