Investigation on the awareness rate of knowledge about sarcopenia prevention and control in elderly patients with cardiovascular disease and analysis of influencing factors
Objective To investigate the awareness of sarcopenia and knowledge about its prevention and control in elderly patients with cardiovascular disease and analyze potential influencing factors for the awareness rate of sarcopenia,in order to provide a theoretical foundation for further developing a precise health education program for elderly patients with cardiovascular disease and sarcopenia.Methods In this multicenter cross-sectional study,the representative sampling method was used via a questionnaire to collect demographic data,a wareness of sarcopenia,and knowledge about its prevention and control from 576 elderly patients aged 60 years and over receiving treatment between March and August 2022 at 12 hospitals including Zhejiang Hospital.Meanwhile,possible influencing factors on the awareness rate of sarcopenia in elderly cardiovascular disease patients were analyzed.Results The overall awareness rate of sarcopenia in elderly patients with cardiovascular disease was 43.2％(249/576).The awareness rates for sarcopenia-related declines in grip strength and walking speed were 39.9％(230/576)and 39.8％(229/576),respectively.The rates of awareness that sarcopenia is more likely to occur in very elderly people was 37.8％(218/576)and the rate of awareness for its more likely occurrence in elderly people with chronic diseases was 29.3％(169/576).The rates of awareness that resistance exercise and protein supplementation could prevent or improve sarcopenia were 33.9％(195/576)and 37.0％(213/576),respectively.Multivariate Logistic regression analysis found that being female and being 70-89 years old were independent risk factors affecting the awareness of sarcopenia and related knowledge about its prevention and control,while high school education and above and living alone were independent protective factors.Conclusions The awareness rate of sarcopenia and knowledge about its prevention and control in elderly patients with cardiovascular disease is low and is significantly correlated to the female gender,advanced age,high educational achievement,living alone and other factors.Therefore,when education about sarcopenia is conducted,a precise health education program for sarcopenia should be established to improve the awareness rate of sarcopenia in elderly patients with cardiovascular disease,thus minimizing or delaying the occurrence and development of sarcopenia as much as possible.
