A paper titled “How much time in sedentary behavior is associated with probable sarcopenia in older adults?” has recently been published in the Geriatric Nursing. The summary of the paper and citation details are re-posted below. The full publication can be found here.
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.
