Study Summary
This study will examine the roles of diet, lifestyle, genes, and their possible interactions in the cause of Parkinson's disease, using information from the NIH-AARP Diet and Health Study. The NIH-AARP study was established in 1995 to examine the roles of diet and lifestyle in cancer. It included 567,169 AARP members 50 or older from California, Florida, North Carolina, Pennsylvania, New Jersey, Louisiana, and the Atlanta and Detroit metropolitan areas. In 1995, participants completed a comprehensive questionnaire on diet and a survey on demographics, medications, as well as a follow-up survey in 1996 with more detailed questions on lifestyle and medications, as well as cooking methods and early life dietary habits. A third followup survey is currently underway. The current NIH-AARP substudy on Parkinson's disease will include approximately 9,000 participants from the NIH-AARP study - 3,000 of whom reported being diagnosed with Parkinson's disease on the most recent survey, and 6,000 control subjects. These study participants provide two saliva samples for genetic analysis and may be asked to complete a telephone interview. In addition, those with Parkinson's disease are asked permission to review medical information regarding their diagnosis.
Primary Outcome
Parkinson s disease diagnosis - we validated Parkinson s diagnosis by collecting and reviewing diagnostic information from study participants and their treating physicians. In addition, we collected saliva sample for genetic assays and additional exposure data for analyses.
