Abstract

OBJECTIVES:

In most reports, the prevalence of PD in mainland China is lower than in western populations. To estimate PD prevalence in China, we performed a cross-sectional study in a rural population in Linxian County, China.

PRIMARY OUTCOMES:

Clinical diagnosis of PD.

RESULTS:

Among the 16,488 participants examined, the overall age- and gender-adjusted prevalence rate of PD was 522/100,000 (95% CI: 477-567) assuming no cases of PD would be found among those younger than 50 years of age. The gender-adjusted prevalence rates were 103 (95% CI: 83-123), 621 (95% CI: 572-670), 902 (95% CI: 843-961), and 1744 (95% CI: 1662-1826) per 100,000 in age groups 50-59, 60-69, 70-79, and 80 and above, respectively.

CONCLUSIONS:

The estimated prevalence of PD in Linxian, China is higher than most of those reported from other areas in China, and similar to those reported from non-Asian populations.
