Study Population
Description
Case population inclusion criteria:
- first Parkinson's disease (PD) diagnosis after January 1998
- currently living in one of the three target counties (Kern, Tulare, Fresno)
- have lived in California for at least 5 years
Case population exclusion criteria:
- have not been diagnosed with idiopathic PD
- first PD diagnosis before January 1998
- currently living outside of Kern, Tulare, or Fresno counties
- have lived in California for fewer than 5 years
Control population inclusion criteria:
- have never been diagnosed with PD
- currently living in one of the three target counties (Kern, Tulare, Fresno)
- have lived in California for at least 5 years
Control population exclusion criteria:
- have been diagnosed with PD
- currently living outside of Kern, Tulare, or Fresno counties
- have lived in California for fewer than 5 years
For each patient, one or more unaffected sibling controls and one population control will be recruited. The population control are being selected randomly from Medicare records (95% of all controls) and residential parcel listings (for those patients younger than 65 years of age only). The controls are being marginally matched to cases according to 5-year age categories (e.g. 50-54, 55-59, 60-64, etc.), race (white, African-American, Asian, Hispanic, other), and sex. All study cases by definition will be patients who elicited care from health care providers. We are aiming to enroll every newly diagnosed PD patient into our study and expect patient population participating in our study that is as diverse as the rural population.
