Study Description

Puerto Rican Elderly: Health Conditions (PREHCO) Wave 2, 2006-2007

Unique Identification Number: QM-504-002-1-2-Puerto Rico-DISC-2006

Summary: PREHCO2 interviewed survivors of the sample interviewed in PREHCO1. It collected information on changes in health, functional limitations, depression, cognition and mortality as well as on family and residential arrangement transitions, familial and non familial transfers, fluctuations in income and assets and, finally, labor force status changes. It has 4,291 cases and 2,766 variables. PREHCO data provides a rich source to examine these areas of research: 1. investigation of uniformly high age and sex-specific prevalence of obesity and self-reported diabetes (type II); 2. investigation of race differentials in measures of health and functional status, 3. assessment of conjectures posing a relation between health and functional limitations of older cohorts and their early childhood experiences of malnutrition and disease; 4. health, functional status and mortality differentials across socioeconomic levels and among individuals with and without migrant experiences in the US. PREHCO 2 presents some significant differences from PREHCO 1. Its questionnaire was adapted to PREHCO 1 data, experimental section E of the questionnaire (Cantrill Scale) was dropped, the experimental symptoms sub-section of the Health section (Section G) was dropped as well, section H (Childhood Conditions) was repeated to evaluated the accuracy and conditionings of remote information provided by the respondents, Section O on Migration was improved, the mistreat section was deleted because of the poor results obtained in PREHCO 1, a number of anthropometric measures and physical efficiency tests were added to those in PREHCO 1, and a new Caregivers Section was added. For those PREHCO 1 participants who died or were institutionalized in the inter-wave period a small versions of the PREHCO 2 questionnaire were answered by their proxies.

Methodology: PREHCO sample is a multistage, stratified sample of the elderly population residing in Puerto Rico with oversainples of regions heavily populated by population of African descent and of individuals over age 80, The data was gathered through face-to-face interviews with elderly adults, including those with cognitive limitations who required the presence of a proxy to provide information, and with their surviving spouses, regardless of age. The field work consisted of interviews conducted with laptop and specialized anthropoinelric measurement and physical performance. More than 20,600 households were visited in 233 sample sections. A total of 4,293 inhome face-to-face target interviews were conducted between May 2002 and May 2003, averaging 114 min in length. In addition 1.444 spouses were interviewed, 1,043 of them 60 or older. The fraction on interviews requiring a proxy was 12.4%. Only 4.7% refused to participate, and the overall response rate was 93.9%. The questionnaire included modules on demographic characteristics, health status and conditions, cognitive and functional performance, labor and economic status, income and assets, health insurance and use of health services, family structure, intergenerational transfers, housing, anthropometrie measurements, and physical performance.
