Abstract：Objective To explore the current prevalence and related factors of periodontal disease among the elderly population in the Bansongyuan Sub-district community of Huangpu District,Shanghai,as well as their prevention strategies.Methods The clinical data of 460 elderly patients who underwent oral examination at Bansongyuan Community Hospital,Huangpu District,Shanghai from July 2021 to December 2022 were included.According to the incidence of periodontal disease,they were divided into the sick group(367 cases)and the healthy group(93 cases).The assessment was conducted based on 10 indicators such as demographics,comorbidities and basic conditions;The logistic method was used to analyze the related factors of periodontal disease in the elderly,establish a prediction model,and analyze the predictive value of the prediction model for periodontal disease in the elderly.Results Periodontal disease occurred in 367 of 460 elderly patients,the incidence rate was 79.78%(367/460).Logistic analysis revealed that the related factors of periodontal disease in the elderly were old age,long-term smoking,drinking,diabetes mellitus,lack of cognition of periodontal disease,no regular oral examination,education level below middle school(P＜0.05).Accordingly,the correlation factor model was established,Logit(P)=-10.638+old age×0.748+long-term smoking×0.694+drinking×0.784+diabetes×0.784+lack of awareness of periodontal disease×0.925+no regular oral examination×0.726+education level below middle school×0.686.The receiver operating characteristic curve(ROC)for predicting periodontal disease in the elderly population was plotted according to the diagnostic probability Logit(P),when Logit(P)>12,the area under the curve(AUC)value was 0.891,95%CI was 0.858～0.918,the sensitivity was 77.38%,and the specificity was 83.87%.Conclusion The incidence of periodontal disease among the elderly population in the Bansongyuan Sub-district community of Huangpu District,Shanghai is relatively high,and it is related to the patients'age,smoking,drinking,diabetes,insufficient awareness of periodontal disease,regular oral examinations,educational level,etc.Based on this,the correlation factor model was constructed to predict the value of periodontal disease in the elderly population of Bansongyuan community in Shanghai Huangpu District.Clinical prevention strategies could be adopted to reduce the risk of periodontal disease.
