Abstract:
The incidence of Parkinson's disease (PD) was studied over a 9-year period (1990-1998) in Tartu county, Estonia, with a mean population of 156,417. Based on 264 patients, the average crude incidence rate of PD was 18.8 per 100,000 person-years. The age-adjusted incidence was 16.8/100,000; 18.3 for the urban group and 14.0 for the rural group; 16.6 for men and 17.1 for women. The age-specific incidence was 1.0/100,000 in the age range 30-39 years, reached a maximum of 117.2/100,000 in the age range 70-79 years and declined in the elderly. The incidence of PD was comparable with that found in developed countries, except for a slightly higher (not significant) incidence rate in the urban compared with the rural population in Estonia.
