Objective: To examine the associations between high-fat/high-sugar foods (HFHS) and fruit and vegetable (FV) consumption and affective states in women.
Methods: The researchers used electronic ecological momentary assessment to capture HFHS and FV consumption in the past 2 hours (predictor) and current affective states (outcome) across 1 week among 202 women. Multilevel linear regression was conducted. Weight status was tested as a moderator.
Results: Consumption of FV in the past 2 hours was positively associated with feeling happy (P < .05). Women who consumed more HFHS or fewer FV than others in the study reported higher average sadness (both P < .05). Overweight or obese women who reported more frequent HFHS consumption than others had higher average stress than normal weight women (P < .05).
Conclusions and Implications: The association between HFHS consumption and stress might be stronger in overweight or obese than normal weight women. Future studies could further enhance the electronic ecological momentary assessment method to explore other time-varying moderators and mediators of food consumption and affect.
