济宁市社区老年人肌少症患病率及其影响因素

Prevalence and influencing factors of sarcopenia in community elderly people in Jining city

目的了解济宁市任城区60岁及以上老年人肌少症患病率情况,分析肌少症患病的影响因素,为今后老年人群肌少症的预防提供依据。方法采用整群抽样法对济宁市观音阁(交通)社区医院健康中心60岁及以上392名老年参与者进行问卷调查、身体成分测量和血液样本收集,并使用SPSS27.0软件进行统计分析。结果任城区社区老年人肌少症总患病率为19.39%,女性和男性患病率相似,差异无统计学意义(χ^(2)=0.02,P=0.889)。与社区老年人肌少症患病有关的因素(OR和95%CI)为:年龄(3.003,1.064~8.476)、BMI(0.061,0.009~0.428)、体力活动水平(0.059,0.014~0.248)、内脏脂肪面积(1.104,1.053~1.157)、LBP(1.165,1.081~1.254)、HS-CRP(5.289,2.297~12.176)、T-AOC(0.000,0.000~0.460)、MDA(3.481,1.261~9.610)及SOD(0.636,0.425~0.920)。结论高龄、内脏脂肪面积以及LBP、HS-CRP和MDA含量增加是社区老年人患肌少症的主要危险因素,而BMI升高、体力活动水平增加、T-AOC和SOD含量增加是其保护因素。

Objective This study aimed to understand the prevalence of sarcopenia among elderly individuals aged 60 and above in Rencheng District,Jining City,and to analyze the influencing factors of sarcopenia,in order to provide theoretical basis for the prevention of sarcopenia in the elderly population in the future.Methods A cluster sampling method was employed to conduct a questionnaire survey,body composition measurement,and blood sample collection among 392 elderly participants aged 60 and above at the Guanyinge(Jiaotong)Community Hospital Health Center in Jining City.Statistical analysis was performed using SPSS 27.0 software.Results The overall prevalence of sarcopenia among elderly residents in Rencheng District was 19.39%,with similar prevalence rates between females and males,and the difference was not statistically significant(χ^(2)=0.02,P=0.889).Factors associated with sarcopenia among community-dwelling elderly individuals(OR and 95%CI)included:age(3.003,1.064~8.476),BMI(0.061,0.009~0.428),physical activity level(0.059,0.014~0.248),visceral fat area(1.104,1.053~1.157),LBP(1.165,1.081~1.254),HS-CRP(5.289,2.297~12.176),T-AOC(0.000,0.000~0.460),MDA(3.481,1.261~9.610),and SOD(0.636,0.425~0.920).Conclusion Advanced age,visceral fat area,LBP,HS-CRP,and MDA are major risk factors for sarcopenia among community-dwelling elderly individuals,while increased BMI,higher levels of physical activity,content of T-AOC and SOD serve as protective factors.
