Abstract
OBJECTIVE: Physical activity patterns over 10-years in relation to changes in body mass index (BMI) and waist circumference (WC) were examined.
DESIGN AND METHODS: Participants (4,880, mean age 49.3 years at baseline) from the Whitehall II cohort study were included. Self-reported physical activity and anthropometric data were collected at baseline (1991) and twice during follow-up (1997 and 2002).
RESULTS: At baseline, meeting established guidelines for physical activity, particularly through vigorous activity, was associated with lower WC (multivariable adjusted B compared to not meeting the guidelines -2.08 cm, 95% CI, -1.39, -0.75) and BMI (-0.34 kg/m(2) , -0.10, -0.59). Based on repeat data, "high adherence" to the guidelines compared to "rare adherence" over follow-up was associated with lower BMI (adjusted difference, -0.43 kg/m(2) , 95% CI, -0.79, -0.08) and WC (-2.50 cm, 95% CI, -3.46, -1.54) at follow-up. Compared to participants that remained stable between 1997 and 2002 (change of <2.5 h/week), those that reported an increase in moderate-vigorous physical activity of at least 2.5 h/week displayed lower BMI (-0.40 kg/m(2) , 95% CI, -0.71, -0.08) and WC (-1.10 cm, 95% CI, -1.95, -0.75).
CONCLUSION: Regular physical activity, confirmed by repeated assessments, is associated with relatively favorable levels of adiposity markers after 10 years follow-up.
