RESUMO:
This study aimed to investigate the association between circadian timing of eating (eating window, time from the midsleep point to first food intake, and time from last food intake to midsleep point) and BMI, and to explore lifestyle-related mediators of these relationships. Adjusted marginal probabilities of excess weight (BMI>24.9 kg/m²) were estimated across tertiles of each circadian timing of eating variable. The shape of the association between these predictors and continuous BMI was analyzed using multiple restricted cubic splines. Mediation analyses were conducted to evaluate the effects of potential lifestyle-related mediators. Forty-nine percent of participants had excess weight. The intervals between the first and last eating events in relation to the midsleep point were positively associated with BMI and the probability of excess weight, while the eating window duration was inversely associated. Diet quality was the strongest mediator in the association between timing of the first eating event and BMI (9.88%), followed by physical activity (1.55%). Similarly, bedtime (–138.8%), sleep duration (–25.23%), and diet quality (–8.10%) mediated the relationship between timing of the last eating event and BMI. Eating window effects were primarily mediated by sleep duration (–18.42%), diet quality (2.95%), and bedtime (2.06%). Our findings suggest that having the first eating event earlier, as well as maintaining a longer eating window, may help prevent and treat excess weight through improvements in sleep, diet quality, and physical activity, highlighting the pathways through which the temporal aspects of eating impact BMI.
