@article {8826, title = {Data Resource Profile: Cross-national and cross-study sociodemographic and health-related harmonized domains from SAGE plus ELSA, HRS and SHARE (SAGE+, Wave 1)}, journal = {International Journal of Epidemiology}, volume = {45}, year = {2016}, month = {Aug-10-2016}, pages = {1403 - 1403j}, abstract = {Four longitudinal studies were included in this rigorous harmonization process: the Study on global AGEing and adult health (SAGE); English Longitudinal Study on Ageing (ELSA); US Health and Retirement Study (HRS); and Survey of Health, Ageing and Retirement in Europe (SHARE). An ex-post harmonized process was applied to nine health-related thematic domains (socio-demographic and economic, health states, overall self-report of health and mental state, health examinations, physical and mental performance tests, risk factors, chronic conditions, social network and subjective well-being) for data from the 2004 wave of each study. Large samples of adults aged 50 years and older were available from each study: SAGE, n = 18 886; ELSA, n = 9181; HRS, n = 19 303; and SHARE, n = 29 917. The microdata, along with further details about the harmonization process and all metadata, are available through the World Health Organization (WHO) data archive at [http://apps.who.int/healthinfo/systems/surveydata/index.php/catalog].

The data resource will continue to be updated with data across additional waves of these surveys and new waves.}, keywords = {Cross-National, ELSA, Older Adults, SAGE, SHARE}, issn = {0300-5771}, doi = {10.1093/ije/dyw181}, url = {http://ije.oxfordjournals.org/lookup/doi/10.1093/ije/dyw181}, author = {Minicuci, Nadia and Naidoo, Nirmala and Chatterji, Somnath and Kowal, Paul} }
