Summary View help for Summary
These are the third and fourth waves of the PREHCO project (Puerto Rican Elder Health Conditions study) and have been developed between 2021 and 2024 as a collaboration between the University of Alabama at Birmingham and the University of Puerto Rico. The project began as a cross-sectional study of the non-institutionalized population aged 60 years or older in Puerto Rico. These waves followed the survivors of the original participants at the beginning of the fieldwork and aimed to examine the predictors of cognitive decline, disability, and mortality. The fourth wave of this study extends the follow-up of PREHCO to between 21 and 22 years after the initial data collection and aims to examine the predictors of cognitive decline, disability, and mortality.
PREHCO was designed as a study comparable to the Multicenter Project on Health and Well-being of Older Adults in Latin America and the Caribbean (SABE) developed by the Pan American Health Organization (PAHO) in several cities in Latin America, and with some studies carried out in the United States, mainly the Health and Retirement Study (HRS).
For this purpose, a questionnaire was designed that included sections on health conditions, physical and mental disability, functionality, use of medicines, health needs and social services, access to and use of health services, abuse, migration, housing conditions, patterns of help from family, community and public and government agencies, and others.
Since its inception, PREHCO has been funded with federal funds from the National Institute on Aging (NIA). Initially it was a project between the University of Wisconsin-Madison and the University of Puerto Rico from 2000-2009.

Each dataset contains a CASEID variable which may be used for linking/merging. When using PREHCO Wave 1 or 2 data including the spouses as independent records (only targets were included in waves 3 and 4), the variable TYPE must be used in the equation (1=target, 2=spouse) since both respondent types share the CASEID.
Sample View help for Sample
For the original sample of PREHCO, a multi-stage, stratified cluster sampling was used, using the 2000 Population and Housing Census of the United States Census Bureau as a sampling frame. The sample included five strata and was representative of the population aged 60 years or older in Puerto Rico and of each of those strata.
The longitudinal follow-up of the fourth wave of PREHCO was carried out on the sample of PREHCO survivors from wave 3, and maintains the characteristics of the original sample design to guarantee the objectives that were planned for the study in its initial phase.

Waves three and four of this study included people aged 77 or older living in households in Puerto Rico, including those unable to answer by themselves and survivors of the original PREHCO participants from 2002-2003.

2025-08-04 This collection has been updated to include files from the Wave 4 data collection and and to add Survey Documentation and Analysis function to priorly released datasets.
2024-07-01 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:
- Performed recodes and/or calculated derived variables.
- Checked for undocumented or out-of-range codes.
Weight View help for Weight
Two weights are included for Wave 3 of the study (Datasets 1 and 3): one for the targets with a direct interview (FACTORT_W3, n=617) and another for all the targets, with a direct interview or through a proxy (FACTORTP_W3, n=811).
HideNotes
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.
This study is maintained and distributed by the National Archive of Computerized Data on Aging (NACDA), the aging program within ICPSR. NACDA is sponsored by the National Institute on Aging (NIA) at the National Institutes of Heath (NIH).
