Physical Activity Linked to Lower Mortality in Parkinson's Disease

Previous research has shown the beneficial effects of exercise on motor and cognitive function, as well as nonmotor symptoms such as mood and sleep in PD. However, these studies were small with relatively short follow-up and few examined the association between physical activity and mortality in this patient population. In the new study, researchers used data from the National Health Insurance Service, a single-payer system providing universal medical coverage for most citizens of South Korea.
@abhishikta Those who reported vigorous activity three or more times per week or moderate or light activity five or more times per week were considered physically active. Otherwise, they were considered physically inactive. To quantify the total amount of physical activity, researchers calculated the metabolic equivalent of task (MET) minutes per week by summing the frequency, intensity, and duration of activity. They categorized the total amount into quartiles.
