Associations of smoking status and leisure-time physical activity with waist circumference change-10-year follow-up among twin adults.

ABSTRACT:

Background

This cohort study investigated the associations of smoking status and leisure-time physical activity (LTPA) with weight circumference (WC) change.

Methods

In the FinnTwin16 cohort, 3322 twins (46% men) reported smoking status, LTPA, and WC in early adulthood and 10 years later providing information on essential covariates at baseline. The effects of smoking status and LTPA (metabolic equivalent tasks [MET]-h/week) on WC change (cm) were estimated by modeling WC value at the end of follow-up and adjusted for baseline WC in linear regression models. Within-pair associations were analyzed using linear fixed-effect regressions among 660 dizygotic and 390 monozygotic twin pairs.

Results

During the 10-year follow-up, 36.4% (n = 273) of baseline daily smokers quit
