Sedentary Behavior Levels and Patterns in Men and Women with Intellectual Disability

Background: There are limited data on the levels and patterns of sedentary behavior (SB) among U.S. adults with ID. Objective: To examine SB levels and patterns in U.S. adults with ID and how these differ between sexes, age-groups, and week vs. weekend days. Methods: Fifty-two adults with ID (25 men; age 45 +/- 14 years) wore a hip accelerometer (wGT3X-BT; Actigraph) during the waking hours for 7 days. We determined total sedentary time, percent of wear time spent sedentary bouts >1, >10, >30, and >60 min, and breaks in sedentary time for bouts >10 min. We examined differences in SB variables as a function of sex, age-group by median split (<48 vs. >48 years), and day of the week. Results: Total sedentary time was 514 +/- 139 min center dot day-1 accumulated in bouts 1-30 min and did not differ between sexes or age-groups. Bouts >1 min across days were longer for men than women and longer during weekend days than weekdays (p < 0.05). The number of bouts >1 min was greater during weekdays than weekend days (p < 0.05). Bouts >60 min were longer for men than women (p < 0.05). The duration of sedentary breaks was longer during weekdays than weekend days (p < 0.001). There were no differences between age-groups. Conclusions: Adults with ID spend a large portion of the day in SB primarily of short bouts. Despite small differences, SB levels and patterns were similar for men and women with ID and across age-groups throughout the week. (c) 2020 Elsevier Inc. All rights reserved.
