Physical activity and diabetes mortality in people with type 2 diabetes: a prospective cohort study of 0.5 million US people
Authors' conclusion
Higher levels of MVPA were associated with lower risk of diabetes mortality among adults with T2DM.
Study context
- Population
- Adults with T2D (age 62 ± 14 years; n 41,726) and without diabetes (age 46 ± 18 years; n 459,660), National Health Interview Survey 1997–2014; mortality from National Death Index41,726 T2D
- Exposure
- Moderate-to-vigorous physical activity (MVPA) categories vs inactive, in adults with T2D
- Outcome
- Diabetes mortality
Methodological detailspopulation-based, Cox regression adjusted for potential confounders
