The relationship between Sarcopenia knowledge and risk in community-dwelling older adults.

This cross-sectional study assessed sarcopenia knowledge among community-dwelling older adults and examined its correlation with the risk of sarcopenia. A total of 434 questionnaires were included for analysis. Knowledge of sarcopenia was evaluated using the Sarcopenia Knowledge Questionnaire (SKQ). The risk of sarcopenia was examined regarding muscle strength and physical performance. The average percentage score on the SKQ was 54.16 ± 14.36 for all participants. They knew the least about screening and diagnosis, followed by lifestyle factors and sarcopenia outcomes. Compared with those without, older adults with a risk of sarcopenia exhibit significantly lower levels of sarcopenia knowledge in all domains, even after adjusting for confounding factors. The risk of sarcopenia decreased by 2 % when the sarcopenia knowledge score increased by 1 point. Community-dwelling older adults exhibit moderate-to-poor knowledge of sarcopenia. A significant negative correlation was found between knowledge of sarcopenia and the risk of sarcopenia. Enhancing sarcopenia-related knowledge and awareness may be an effective strategy for prevention; however, further research is needed to determine the effectiveness of health education in achieving these outcomes.
