  • Baseline Questionnaire (PDF - 24MB): This is the original questionnaire mailed in 1995-1996 to 3.5 million AARP members that established a cohort of 566,398 persons.
  • Risk Factor Questionnaire (PDF - 19MB): This questionnaire contains questions about past diet and other health-related information. The Risk Factor cohort contains 334,905 persons.
  • Follow-up Questionnaire (PDF - 478kb): This questionnaire was sent to all living participants in the baseline cohort at the end of September 2004. It asked participants about their physical activity, retirement status, medication use (including hormones), cancer status and other non-cancer endpoints, and family history of cancer.

Parkinson's Genes and Environment (PAGE) Study

We initiated a study to find the causes of Parkinson’s disease. This study, the Parkinson’s, Genes and Environment (PAGE) Study, is a collaborative effort between us and another branch of NIH, the National Institute of Environmental Health Sciences (NIEHS). The purpose of this study is to determine the effects of diet, lifestyle, and other environmental and genetic factors on the risk of Parkinson’s disease.

Parkinson’s Disease is a common brain disease among elderly people, affecting more than 1% of elderly Americans. For your information, we have prepared a brief Fact Sheet on Parkinson’s disease.

The PAGE study is designed to investigate the environmental and genetic causes of Parkinson’s disease. In this project, we will confirm the disease diagnosis for those who reported Parkinson’s disease in our recent survey (2004-2006). We will also collect saliva samples from Parkinson’s patients and some selected participants without Parkinson’s disease. To learn more about the study and how you can help, please read our short study materials: Patient Invitation Letter, Control Invitation Letter, Patient Brochure and Control Brochure.

Please note that for the saliva collection in the PAGE study, all you need to do is to spit 2 milliliters of saliva into the collection kits we send to you; please visit Saliva Collection Instruction for details.

If you receive an invitation letter from us, please consider participating in this important study. With your participation, we hope to make this study one of the largest research efforts on Parkinson’s disease. Your participation is crucial for its success, which may lead to better ways to prevent and treat Parkinson’s disease.

If you have any questions, please contact the Principal Investigator, Dr. Honglei Chen or the study manager, Heidi Staub at 1-800-948-7552 Ext 355.
