上海浦东南部地区60岁以上老年群体肌少症流行率、影响因素及中医证候特征分析OA

Objective Given the accelerating aging population and regional differences in the sarcopenia prevalence,this paper focuses on the urban-rural transitional area in the south part of Pudong,Shanghai.The goal is to investigate the prevalence of sarcopenia among the elderly population in Pudong,explore its influencing factors,and analyze the distribution of traditional Chinese medicine(TCM)syndromes,providing evidence for the development of localized prevention and intervention strategies.Methods A convenience sampling method was used to recruit elderly residents in the south part of Pudong,Shanghai,who underwent health examinations.Sarcopenia was diagnosed according to relevant criteria,and the prevalence was calculated.Demographic information,lifestyle and occupational history,physical data,and chronic disease history were collected.Univariate analysis was conducted to identify potential influencing factors for sarcopenia,followed by multivariate logistic regression analysis.TCM syndrome differentiation was conducted for sarcopenia patients to analyze the syndrome characteristics.Results ①The overall prevalence of sarcopenia was 6.42%,with no significant gender differences(P=0.841).②Univariate analysis indicated associations between sarcopenia and farming or diabetes(P<0.05).Multivariate logistic regression showed that farming was an independent protective factor for sarcopenia[a OR=0.050,95%CI(0.021–0.119),P<0.001].No independent association with diabetes was observed in this study,which may be related to sample size and study design limitations.③Among the 42 sarcopenia patients,the predominant TCM syndromes were liver-kidney deficiency syndrome(47.62%)and spleen-stomach deficiency syndrome(45.24%).Conclusions Farming experience was associated with a lower risk of sarcopenia,liver-kidney deficiency syndrome and spleen-stomach deficiency syndrome were the predominant TCM syndromes.Given the use of convenience sampling and the limited sample size,these findings serve as a preliminary reference for the south part of Pudong.Lifestyle-based interventions and integrated TCM and Western rehabilitation approaches targeting the liver,spleen,and kidney may be beneficial for sarcopenia prevention and management in older adults.
