Abstract: Objective To investigate the prevalence of Parkinson disease （PD） among elderly residents in the community and its related influencing factors, so as to provide a scientific basis for formulating prevention and control measures tailored to local conditions. Methods From June to September in 2019, residents aged over 60 years old in six communities of Qiqihar City were selected by multi-stage stratified cluster random sampling method for PD screening, and those with positive screening results were diagnosed by neurologists according to the diagnostic criteria. Descriptive epidemiological analysis was used to analyze the prevalence of PD, and univariate and multivariate analysis were used to analyze the influencing factors of PD. Results In this study, a total of 8 645 community residents aged over 60 years old in Qiqihar City were investigated. The age ranged from 60 to 93, the average age was （72.36 ± 5.22） years. There were 3 864 males and 4 781 females. Among them, 169 cases of PD were detected, and the prevalence rate was 1.95%. Higher education level （OR=0.581 in primary school, OR=0.352 in junior high school and above）, regular exercise （OR=0.554） were the protective factors of PD, while male（OR=1.634）, older age （OR=1.673 in 70 -79 years, OR=1.973 in 80 - 93 years）, stroke（OR=1.451） and family history（OR=1.712） were the risk factors of PD. Conclusion The prevalence of PD in community residents aged over 60 years old in Qiqihar is relatively high, male and the elderly with stroke and family history of PD are high-risk groups. Appropriate exercises should be maintained for PD prevention.
