Living a sedentary lifestyle has put more than one-quarter of adults worldwide at risk for serious disease. Current guidelines call for at least 150 minutes of moderate-intensity physical activity or 75 minutes of vigorous-intensity physical activity per week. Based on an analysis of survey data, researchers report that nearly one-third of women and one-quarter of men worldwide failed to meet these levels in 2016, placing them at a higher risk for heart disease, diabetes, dementia, and certain types of cancer.
