Introduction: Prevalence of Parkinson’s Disease (PD) in the Philippines has been estimated to be < 1 % based on a 2007 nationwide survey conducted by the Philippine Neurological Association, but without case ascertainment. Since there is still paucity of data, we aim to determine the prevalence of PD in a rural community and the possible predisposing factors on the development of the disease. Methods: This is a two-phase descriptive study which investigated the prevalence of PD and associated risk factors in a randomly selected rural community in Candelaria, Quezon Province. A validated screening questionnaire was utilized, and case ascertainment was done in eligible respondents. Results: A total of 365 respondents aged ≥ 20 years were randomly surveyed from 2016 to 2017. Two cases of PD aged ≥ 60 years were reported. Thus, the prevalence of PD in the community was 0.55 %. Age-specific prevalence of PD among individuals ≥ 60 years was 4.35 %.Insecticide use was infrequent in the community and was recorded in one PD patient. Protective factors like smoking and drinking tea were not observed in both cases whereas coffee intake was reported in one PD patient. Conclusion: This community-based epidemiologic study on PD is consistent with a nationwide study. The study portrayed certain demographic and environmental features inherent in a community, which are potential confounding variables in PD development. Future larger population studies be recommended to establish PD in the advancing age and to further support the link of various factors with PD.
