The associations between carbohydrate and protein intakes with habitual sleep duration among adults living in urban and rural areas

摘要

Background & aims: Macronutrient intake was associated with habitual sleep duration, a recognized metabolic risk factor. However, results are not clear for populations with large diversities in dietary habits and urbanization levels. In this study, we aimed to evaluate the associations between relative macronutrient intakes and sleep duration, and the potential modification effect of urban-rural residence among adult Chinese population.
