a
The mean (95% CI) is the adjusted mean change in WC (cm) and HC (cm) in both the non-constant active and constant active groups and different levels.
b
Adjusted for age, baseline (WC or HC), BMI, and LTPA.
c
Adjusted for the same variables as in model 1 as well as alcohol, smoking, education, and, in women, menopause status.
d
Adjusted for the same as in model 2 as well as LTPA and OPA at the second follow-up.
e
p value of analysis of variance (ANOVA) test < 0.05.
WC = Waist circumference; HC = hip circumference; LTPA = leisure time physical activity; OPA = occupational physical activity.
