||Established Populations for Epidemiologic Studies of the Elderly
||The Established Populations for Epidemiologic Studies of the Elderly (EPESE) is a longitudinal prospective study, funded by National Institute on Aging. The EPESE sample consists of non-institutionalized individuals age 65 and older in four communities: East Boston, Massachusetts; two rural counties in Iowa; New Haven, Connecticut, and central North Carolina. The purpose of the study is to understand the predictors of mortality, hospitalization, and risk factors for chronic diseases, functional decline, and admission to long-term care facilities. The study consisted of a preliminary baseline household interview of participants followed annually. Information from hospital/state records and death certificates are also included.

||1981--1993 Approximately 14,456
East Boston (N = 3,809), Iowa (N = 3,673), New Haven (N = 2,811), and North Carolina (N = 4,165).
First follow-Up: 14,070
Second follow-Up: 13,382
Third follow-up: 12,381
Fourth follow-up: 11,657
Fifth follow-up: 10,998
Sixth follow-up: 9,998
Deaths during follow-up: 4,238
Lost to follow-up:220
|Unit of Observation
||East Boston, Massachusetts, New Haven, Connecticut, Iowa (Iowa and Washington counties), five counties in north central North Carolina
|Data Collection Mode
||Baseline: In-person interview
Follow-up: Phone and in-person interviews depending on wave.
Data supplemented by hospital and state data system health service records and death certificate information.
|Data Collection Frequency
||Baseline Data: 1980-81 (varies with site)
6 approximately annual follow-up interviews.
||Strengths and limitations
||Longitudinal design of the survey assists in identifying risk factors of diseases, disabilities, hospitalizations, institutionalization, and mortality.
Large community-based sample and high initial response rate (80% and higher).
Attrition for reasons other than death was minimal.
Males were oversampled to maintain balance in the gender distribution. North Carolina sample consists of at least 50 percent African-Americans.
Small sub-sample had blood samples taken in sixth follow-up.
||Sample not nationally representative. High proportion (up to 20%) of oldest cohorts data based on proxy responses. Some variation in survey content by study location.
Study relied on self-reported information on chronic disease, hospitalization, and nursing home service. Very limited nutrition/diet information.
