Objective: To determine how the body mass index (BMI) structure (underweight, normal weight, overweight, and obesity grades I and II) affects the physical activity structure (light physical activity, moderate physical activity, and vigorous physical activity), sleep, sedentary behaviour, eating habits, stress, depression, health, and emotional intelligence.Results: We determined that health and stress depended on the BMI structure only among women and Emotional Intelligence depended on the body mass index structure only among men. Emotional Intelligence was higher among overweight and obese men than normal weight and underweight men. We found that light physical activity in women and men, and especially vigorous physical activity METs structures, sedentary, significantly were associated with the BMI structure, whereas sleep METs didn’t depend on the BMI structure in women and men. As BMI increases, vigorous physical activity significantly decreases in men and women. We identified a significant direct correlation relationship between vigorous physical activity and eating breakfast. We found that of all energy expenditure determinants vigorous physical activity had the best correlation with the BMI structure among women and men. We identified that BMI was closely and directly associated with the frequencies of overeating and skipping breakfast among women and men.
