Patterns of Sedentary Behavior in US Middle-Age and Older Adults: The REGARDS Study.

ABSTRACT:

Results

The number of sedentary bouts greater than or equal to 20, 30, 60, and 90 min were 8.8 ± 2.3, 5.5 ± 1.9, 1.9 ± 1.1, and 0.8 ± 0.7 bouts per day, respectively. Sedentary bouts greater than or eq
