ABSTRACT

Sedentary activities, such as watching television and using the computer, are frequent conditions in older adults and can be associated with sarcopenia. The objectives of this study were: (a) to establish sedentary behavior (SB) cutoff values for screening probable sarcopenia in community-dwelling older adults and (b) to verify the association between SB and probable sarcopenia according to the established cutoff point. This was a cross-sectional study including 1,165 community residents in Florianopolis/SC. SB was assessed using the International Physical Activity Questionnaire. The outcome was probable sarcopenia (assessed by time ≥ 15 s in the Five times sit-to-stand test). The cut-off points found for SB were time > 120 min/day [AUC: 0.54 (95%CI: 0.51; 0.57)] watching TV or video/DVD and ≤ 20 min/day [AUC: 0.59 (95%CI: 0.56;0.62)] using computer/internet. Older adults with SB had 1.30 (95% CI: 1.01; 1.66) and 1.46 (95% CI: 1.08; 1.96) greater chances of having sarcopenia, respectively.
