The association of sitting time with sarcopenia status and physical performance at baseline and 18-month follow up in the residential aged care setting.

This study investigated the association of sitting time with sarcopenia and physical performance in Residential Aged Care (RAC) residents at baseline and 18-month follow-up. Measures included the International Physical Activity Questionnaire (sitting time), European Working Group definition of sarcopenia, and the Short Physical Performance Battery (physical performance). Logistic regression and linear regression analyses were used to investigate associations. For each hour of sitting the unadjusted odds ratio of sarcopenia was 1.16 (0.98 - 1.37). Linear regression showed that each hour of sitting was significantly associated with a 0.2-unit lower score for performance. Associations of baseline sitting and follow-up sarcopenia status and performance were non-significant. Cross-sectionally, increased sitting time in RAC may be detrimentally associated with sarcopenia and physical performance. Based on current reablement models of care, future studies should investigate if reducing sedentary time improves performance among adults in end of life care.
