Abstract：Objective:To investigate the incidence and influencing factors of community-acquired pneumonia in elderly communities.Method:One hundred and ten elderly patients with community-acquired pneumonia admitted to the sample hospital from January 2020 to January 2025 were selected as the observation group,and 110 elderly non-community-acquired pneumonia patients matched by community and gender during the same period were selected as the control group.Age,BMI,nutritional status(albumin level),history of dust occupation,smoking status,alcohol consumption,history of pneumonia within 1 year,history of cardiovascular disease,respiratory disease,diabetes mellitus,hypertension,and malignancy were compared between the two groups to analyse the factors influencing the occurrence of community-acquired pneumonia in the elderly by logistic regression.Result:There were no statistically significant differences between the two groups in terms of age,body mass index(BMI),alcohol consumption,history of cardiovascular or cerebrovascular disease,hypertension,or malignant tumours(P>0.05).The proportion of participants in the observation group with albumin levels<35 g/L,occupational exposure to dust,smoking history,history of pneumonia within the past year,respiratory diseases,and diabetes was higher than that in the control group,with statistically significant differences(P<0.05).Logistic regression analysis revealed that albumin<35 g/L,occupational exposure to dust,smoking status,history of pneumonia within the past year,respiratory diseases,and diabetes mellitus were significant risk factors for community-acquired pneumonia in the elderly.Conclusion:The occurrence of community-acquired pneumonia in the elderly is strongly influenced by a number of factors,including basic personal circumstances,living habits and diseases,which can be used as a reference for the development of preventive and control measures for the disease.
