The aim of this study was to identify the factors related to and determine the prevalence of Parkinson's disease (PD) among Uygur residents in Hetian Prefecture, Xinjiang Uygur Autonomous Region.This population-based prospective cohort study used structured questionnaires to screen for factors related to PD.The prevalence in different age groups was analyzed, and PD risk was assessed using univariate and multivariate conditional logistic regression analysis.In total, 5932 subjects participated in the survey; of these, 88 individuals, all of whom were Uygurs, had PD.The overall prevalence of PD was 1.48% (1.32%) in people over the age of ©FUNPEC-RP www.funpecrp.com.brGenetics and Molecular Research 14 (3): 8539-8546 (2015) 45; the prevalence was 1.68% (1.59%) in men and 1.28% (1.36%) in women.The Fifth Population Census in China found the prevalence of PD in Hetian, Xinjiang, to be 1.32%.Single-factor results showed that exercise, social activities, and frequent consumption of nuts are protective factors for PD, and long-term pesticide exposure, family history of PD, and consumption of barbecued food were risk factors for this condition.Multi-factor conditional logistic regression analysis showed that participation in sports and social activities can reduce the risk of PD, whereas long-term pesticide exposure and family history of PD increases this risk.These results show that PD is caused by the interaction of several factors.
