Sedat adferd og fysisk funksjon hos hjemmeboende unge og middelaldrende personer etter hjerneslag

Abstract

Sedentary behaviour is linked to cardiovascular disease morbidity and mortality. To date, no studies have used objective measures to investigate sedentary behaviour in community dwelling young and middle-aged stroke survivors. Objective: To investigate sedentary behaviour, and its relationship to physical function, in community dwelling young and middle-aged stroke survivors. Methods: Participants were fitted with ActivPAL3 accelerometer and the device was worn 24 hours a day for seven consecutive days, from which sedentary time and transitions per 24 hours were calculated. A questionnaire was used for self-report on sedentary time. Physical function was measured using Short Physical Performance Battery, gait speed, Fatigue Severity Scale, and Becks Depression Inventory. Descriptive statistics and Spearman's rank-order correlation test were used for the data analysis. Results: 13 (31 % women, 69 % men) participated in the study. Median age was 46 years, mean time from stroke onset to testing was approximately 6, 5 months. Participants spent 80 % of the 24-hour day in sedentary behaviours (median = 18,8 hours, IQR =17, 7-20,0 hours), with 51 (IQR) transitions (39-70). Participants underestimated sedentary time by self-report. Sedentary time was weakly correlated with physical function, whereas the correlations between number of transitions and physical function were moderate to strong: Short Physical Performance Battery (ρ =,46), gait speed (ρ =,60), fatigue (ρ =,57) and depression (ρ =,41). Conclusion: Participants were highly sedentary. Further work is required to investigate potential influencing factors and the context of sedentary behaviour in different subgroups post-stroke. Recruiting participants was challenging in this study, and larger, preferably multisite studies are recommended.
