BMI: body mass index; HT: hypertension; NS: non-significant;

PA: physical activity.

^acomparisons between overweight vs. normal weight, obese vs. normal-weight, smokers vs. non-smokers, high PA vs. low PA and high vigorous PA vs. low vigorous PA weighted for group sizes.

^bThe cut-off point for low vs. high vigorous PA was set at 1500 MET^.min^.wk^-1 of vigorous PA.
