Research on Early Life and Aging Trends and Effects (RELATE): A Cross-National Study (ICPSR 34241) RSS

Principal Investigator(s):

Summary:

The Research on Early Life and Aging Trends and Effects (RELATE) study compiles cross-national data that contain information that can be used to examine the effects of early life conditions on older adult health conditions, including heart disease, diabetes, obesity, functionality, mortality, and self-reported health. The complete cross sectional/longitudinal dataset (n=147,278) was compiled from major studies of older adults or households across the world that in most instances are representative of the older adult population either nationally, in major urban centers, or in provinces. It includes over 180 variables with information on demographic and geographic variables along with information about early life conditions and life course events for older adults in low, middle and high income countries. Selected variables were harmonized to facilitate cross national comparisons.

In this first public release of the RELATE data, a subset of the data (n=88,273) is being released. The subset includes harmonized data of older adults from the following regions of the world: Africa (Ghana and South Africa), Asia (China, India), Latin America (Costa Rica, major cities in Latin America), and the United States (Puerto Rico, Wisconsin). This first release of the data collection is composed of 19 downloadable parts: Part 1 includes the harmonized cross-national RELATE dataset, which harmonizes data from parts 2 through 19. Specifically, parts 2 through 19 include data from Costa Rica (Part 2), Puerto Rico (Part 3), the United States (Wisconsin) (Part 4), Argentina (Part 5), Barbados (Part 6), Brazil (Part 7), Chile (Part 8), Cuba (Part 9), Mexico (Parts 10 and 15), Uruguay (Part 11), China (Parts 12, 18, and 19), Ghana (Part 13), India (Part 14), Russia (Part 16), and South Africa (Part 17).

The Health and Retirement Study (HRS) was also used in the compilation of the larger RELATE dataset (HRS) (n=12,527) and these data are now available for public release on the HRS data products page . Once you are on the HRS data products page, click on "Access to Public Data" link. You need to be a registered user to download the HRS RELATE data file. Registration is free and fairly easy. When you log in to the HRS data download system, click on the "Data Downloads" link on the bottom of the login screen. Then look for RELATE files in the "Research Contributions" area (upper right corner of the data downloads screen). HRS RELATE data file is in Stata format. A codebook file and a metadata file are included. Once downloaded HRS data can be appended to this release of harmonized cross-national RELATE data file.

Methodology

Study Purpose:   The purpose of this study was to compile and harmonize cross-national data from both the developing and developed world to allow for the examination of how early life conditions are related to older adult health and well being.

Study Design:  

The selection of countries for this study was based on their diversity but also on the availability of comprehensive cross sectional/panel survey data for older adults born in the early to mid 20th century in low, middle and high income countries. These data were then utilized to create the harmonized cross-national RELATE data (Part 1).

Specifically, data that are being released in this version of the RELATE study come from the following studies:

CHNS (China Health and Nutrition Study)

CLHLS (Chinese Longitudinal Healthy Longevity Survey)

CRELES (Costa Rican Study of Longevity and Healthy Aging)

PREHCO (Puerto Rican Elderly: Health Conditions)

SABE (Study of Aging Survey on Health and Well Being of Elders)

SAGE (WHO Study on Global Ageing and Adult Health)

WLS (Wisconsin Longitudinal Study)

Note that the countries selected represent a diverse range in national income levels: Barbados and the United States (including Puerto Rico) represent high income countries; Argentina, Cuba, Uruguay, Chile, Costa Rica, Brazil, Mexico, and Russia represent upper middle income countries; China and India represent lower middle income countries; and Ghana represents a low income country.

Users should refer to the technical report that accompanies the RELATE data for more detailed information regarding the study design of the surveys used in the construction of the cross-national data.

Sample:  

Most studies included in the RELATE data are representative of the older adult population either nationally, in major urban centers or in major provinces. Some studies are representative samples of households from which older adults were selected. In almost all cases studies obtained very respectable response rates.

Users should refer to the technical report that accompanies the RELATE data for more detailed information regarding the sampling of older adults used in the construction of the cross-national data.

Weight:   Sample weights are applicable to all countries except the United States (Wisconsin) Data and the China (CHNS) Data. Most country-specific surveys had a single sample weight variable. These surveys included: China (CLHLS), Costa Rica, Puerto Rico, SABE, and SAGE.

Description of Variables:   The Research on Early Life and Aging Trends and Effects (RELATE) data includes an array of variables, including basic demographic variables (age, gender, education), variables relating to early life conditions (height, knee height, rural/urban birthplace, childhood health, childhood socioeconomic status), adult socioeconomic status (income, wealth) adult lifestyle (smoking, drinking, exercising, diet), and health outcomes (self-reported health, chronic conditions, difficulty with functionality, obesity, mortality). Not all countries have the same variables. Please refer to the technical report that is part of the documentation for more detail regarding the variables available across countries.

Response Rates:   All studies included in the Research on Early Life and Aging Trends and Effects (RELATE) database obtained very respectable response rates. Please refer to the technical report that accompanies the data for more information.

Presence of Common Scales:   Several Likert-type scales were used

Extent of Processing:  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 consistency checks.
  • Created variable labels and/or value labels.
  • Checked for undocumented or out-of-range codes.
