Version V1

The Hispanic Established Populations for Epidemiologic Studies of the Elderly (EPESE) Frailty Study sought to apply a standard definition of frailty in a well-defined sample of Mexican American older adults and to examine the impact of frailty on disability, health related quality of life, institutionalization, and mortality in this population over time. This project is a continuation of a prior study (the Hispanic EPESE) examining the enabling-disabling process in this same population of aging Mexican Americans; data were collected from 1,031 older adults who were participating in the Hispanic EPESE. Only subjects who were physically capable of safely completing the muscle strength measures were included. Baseline interviews were collected for this subsample in 2006/2007 during Wave 6 (ICPSR 29654) of the Hispanic EPESE study. This collection includes data about respondents' health status, activities of daily living and their ability to perform tasks. Two-year follow-up data were collected in 2008/2009 from 731 participants in Wave 1. Demographic and background information include age, relationship status, gender, marital status and household composition.

This collection is related to the Hispanic Established Population for the Epidemiological Study of the Elderly (Hispanic EPESE) Series. These data can be linked to all waves in the Hispanic EPESE Series using the participant ID variable (Q_NO).

The EPESE project has a prospective design including an initial cross-sectional baseline survey, with annual follow-up contacts of all participants and continual surveillance of mortality and use of hospitals and nursing homes. The Hispanic EPESE follows the same design as the earlier EPESE projects. Data from the baseline survey of the Hispanic EPESE provides estimates of the prevalence of specific chronic conditions and impairments for the population of older Mexican Americans, as well as baseline data for prospective studies of participants. The baseline survey of the Hispanic EPESE was conducted from the Fall of 1993 through the Spring of 1994. The baseline and all follow-up interviews have been conducted face-to-face, in respondents' homes. The cohort was under continual surveillance to monitor the occurrence of deaths, hospitalizations, and admissions to nursing homes. Reports of these events were provided through the follow-up interviews, and additional information was obtained from organized data systems. For additional information about Study Design, please refer to the ICPSR 4314 User Guide.

These data are a convenience subsample drawn from ICPSR 29654.

2016-03-29 ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Checked for undocumented or out-of-range codes.

The data contain no weights and are not weighted.


  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.
