M, male; F, female; SD, standard deviation; BMI, body mass index; WC, waist circumference; Sleep hours (A/B/C), A, less than 6 hours, B, between 6 and 8 hours, C, more than 8 hours; Y, yes (presence); N, no (absence); CVD, cardiovascular diseases; T2DM, type 2 diabetes mellitus.
P values were calculated comparing obese vs. lean only, Fisher and Student’s t tests were applied as appropriate.
