Physical activity and sedentary behavior among adults 60 years and older: New York city residents compared with a national sample

This study describes moderate to vigorous physical activity (MVPA) and sedentary behavior among New York City (NYC) residents 60 years and older and compared with national United States' estimates. Adults aged 60 or older living in NYC (n = 760) were compared with similar aged adults from the National Health and Nutrition Examination Survey (NHANES; n = 2,451 adults). Both groups wore an ActiGraph accelerometer for one week. The NYC sample recorded 13.2, 23.8, and 37.8 mean min/day of MVPA and the NHANES sample recorded 10.6, 21.1, and 39.3, depending on the definition. Sedentary behavior averaged 9.6 hr/day for the NYC sample and 9.3 hr/day for the NHANES sample. The NYC sample spent a longer proportion of time in sedentary behavior and light activities, but more time in MVPA than the NHANES sample. Urbanicity may explain some of the differences between the two samples.
