Prevalence and influencing factors of sarcopenia in community elderly people in Jining city
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(χ2=0.02,P=0.889).Factors associated with sarcopenia among commu-nity-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,con-tent of T-AOC and SOD serve as protective factors.
