Acti= wrist actigraphy measure. BMI= Body Mass Index; PSQI= Pittsburgh Sleep Quality Index; WASO= Wake After Sleep Onset. HOMA-IR= Homeostatic model of assessment- insulin resistance. CRP= C-reactive protein. Note: Missing data n=2 exercise and n=3 non-physical activity for HbA1c, n= 1 exercise and n=1 non-physical activity for CRP. P values were >0.05 for all comparisons between groups on pre-treatment variables.
