  • U.S. public: U.S. public general population comparison sample is an age- and gender-matched sample of living non-Veteran members of the U.S. public born before 1958. 



Data Collected

Demographics and health-related topics including

  • Military service, such as service experience, combat experience, chemical and other exposures, re-entry into civilian life, or no military service
  • General health, such as neurologic conditions, Hepatitis C, hypertension, ischemic heart disease, Type II diabetes, peripheral neuropathy, various cancers, cirrhosis, alcohol and drug dependency, posttraumatic stress disorder (PTSD), and depression
  • Age-related conditions, such as memory, reasoning, and limitations
  • Lifestyle, such as and tobacco use, health care use, living arrangements, and health experiences of descendants

Data Collection Methods

Data collected via questionnaire.

A subset of participants provided investigators with access to their medical records. Hepatitis C and neurologic conditions validated by medical record review.
