Maintaining Physical Activity Is Associated with Reduced Major Adverse Cardiovascular Events in People Newly Diagnosed with Diabetes.

Background: We investigated the association between changes in physical activity and the risk of a major adverse cardiovascular event (MACE) in people with newly diagnosed diabetes.

Methods: Using a nationwide database, we identified 8,596 people with newly diagnosed diabetes who underwent national health examinations within a year before and after a diabetes diagnosis. Cox proportional hazards models, hazard ratios (HRs) and 95% confidence intervals (CIs) for MACE risks were calculated according to changes in physical activity before and after a diagnosis of diabetes.
