Analysis of sedentary behaviour levels and patterns in adults with Down syndrome.

Background: Sedentary behaviour (SB) among adults with Down syndrome (DS) may differ based on personal or environmental factors. Objective: Investigate differences in SB levels and patterns of adults with DS based on sex, age, and residence‐type across weekdays and weekends. Methods: Thirty‐four adults with DS (15 men; 37 ± 12 years) underwent accelerometry‐based measurements of sedentary time, bouts, and breaks for 7 days. We evaluated differences with 2 × 2 mixed‐model (group‐by‐day) ANOVA. Results: Younger (19–36 years) individuals had less sedentary time (p =.042), and shorter (p =.048) and fewer (p =.012) bouts than older (37–60 years) individuals. Group home residents had more bouts on weekends than adults living with parent/guardians (p =.015). Conclusions: Adults with DS spent half their waking hours in SB of short bouts. Age and residence may influence SB. [ABSTRACT FROM AUTHOR]
