History of this Study

From 1995 through 1996, we mailed 3.5 million questionnaires to current members of the AARP (formally the American Association of Retired Persons), aged 50-71 years, and who resided in one of six states (California, Florida, Pennsylvania, New Jersey, North Carolina, and Louisiana) or in two metropolitan areas (Atlanta, Georgia and Detroit, Michigan). The questionnaire included a dietary section as well as some lifestyle questions. Over 500,000 people returned the questionnaire, making this the largest study of diet and health ever conducted! In 1996-1997 we mailed our participants a Risk-Factor Questionnaire which asked additional questions about lifestyle and behavior. In 2004-2006 we’ve mailed our follow-up questionnaire.
