Investigation on the Prevalence and Risk Factors of Osteoarthritis among the Elderly in the Community of Wuzhou City,Guangxi
Objective To explore the prevalence and epidemiological trend of osteoarthritis in the elderly,and to analyze the risk factors of osteoarthritis in the elderly,so as to provide data reference for clinical screening of osteoarthritis in the elderly.Methods From January 2018 to December 2022,a survey of osteoarthritis was conduc-ted among the elderly in 26 communities in Wuzhou city,Guangxi by multi-stage stratified sampling(including ques-tionnaire,physical examination and laboratory examination)to understand the prevalence of osteoarthritis in the el-derly in the community.Logistic regression model was used to analyze the risk factors of the elderly in the communi-ty.Results A total of 2 958 elderly patients with osteoarthritis were included in the questionnaire,including 1 904 patients with osteoarthritis,with an overall prevalence rate of 64.37％.Single focus of lower limb accounted for 49.69％(946/1 904),upper limb single focus accounted for 16.54％(315/1 904),single focus of spine accounted for 20.85％(397/1 904),multiple lesions accounted for 12.92％(246/1 904).The annual prevalence rate of osteoarthri-tis increased year by year from 2018 to 2022(x2=10.213,P＜0.05).The total prevalence rate of osteoarthritis in the elderly is significantly higher in females than in males(x2=7.564,P＜0.05).And the prevalence rate increased sig-nificantly with the increase of age(x2=28.318、10.711、10.910、11.531、11.208,P＜0.05).Univariate analysis showed that female,living stairwell,previous physical work/exercise history,family history,smoking history,osteo-porosis history,diabetes history,hypertension history,chronic kidney disease history,cardio-cerebrovascular disease history,BMI and age were associated with osteoarthritis among the elderly in the community(x2=7.564、6.705、32.152、8.754、77.485、17.827、15.469、6.784、14.474、7.983、8.468,P＜0.05).Logistic analysis showed that fe-male(OR=2.620,95％CI:1.059-6.479),living stairwell(OR=3.025,95％CI:1.178-7.766),previous physical work/exercise history(OR=3.177,95％CI:1.223-8.253),family history(OR=1.719,95％CI:1.051-2.812),smoking history(OR=2.038,95％CI:1.057-3.930),osteoporosis history(OR=3.483,95％CI:1.336-9.083),dia-betes history(OR=2.298,95％CI:1.100-4.802),hypertension history(OR=3.277,95％CI:1.201～8.940),chro-nic kidney disease history(OR=2.670,95％CI:1.193-5.975),cardio-cerebrovascular disease history(OR=2.358,95％CI:1.015-5.478),BMI(OR=2.096,95％CI:1.083-4.057)and age(OR=3.721,95％CI:1.394-9.934)were all risk factors for osteoarthritis among the elderly in the community(P＜0.05).Conclusion In the past 5 years,the prevalence rate of osteoarthritis among the elderly in the community of Wuzhou,Guangxi city is increasing year by year.According to the analysis of different demographic characteristics,past medical history and life history,we can screen,prevent and control the high-risk elderly who are prone to osteoarthritis.
