Notes: β represents the change in FEV1/FVC%pred with a 30-minute increase per day in the movement behaviour for single activity and partition models, and for a 30-minute substitution in isotemporal substitution models. All models were adjusted for age, sex, smoking status, retirement status, education and body mass index. Source: The Canadian Longitudinal Study on Aging. |
