Assessment of dietary intake and physical activity
Energy and nutrients intake were estimated using 24-h dietary recalls for three nonconsecutive days (2 weekdays and one weekend day) and then were analyzed using Nutritionist IV (N-Squared Computing, San Bruno, CA, USA). Physical activity was evaluated using international physical activity questionnaire (IPAQ) for three days (two regular days and one weekend day). It was expressed as MET.h/day by multiplying the time of each physical activity by its relative Metabolic Equivalent Task (MET).
