- Description
- The effort to create SAGE+ Wave 2 (2010) follows from the harmonized dataset generated for SAGE+ Wave 1 (2004) whose details can be found in Minicuci et al. The SAGE+ Wave 2 harmonization included the previous four studies, 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), and introduced two additional studies: Wave 1 of the China Health and Retirement Longitudinal Study (CHARLS) and the pilot of the Longitudinal Aging Study in India (LASI). The outcome of the harmonization work leading to SAGE+ Wave 1 and SAGE+ Wave 2 is two common datasets that will allow a wide range of cross-country comparisons and evaluation of the predictors of transitions in various domains, from subjective health status and risk factors shifts, to evaluation in relationships between wealth and health in countries at different levels of development. Details about the decisions and methods used for the harmonization process for SAGE+ Wave 1 are available in Minicuci et al. 2016. The aim of this article is to present the analogous results for SAGE+ Wave 2 which extends and adds unique data to SAGE+ Wave 1. The harmonization process for SAGE+ Wave 2 builds on SAGE+ Wave 1 processes and follows the same methodology. SAGE+ Wave 2 included the two additional studies, CHARLS and LASI, whose variables were subjected to the same harmonization process as used in SAGE+ Wave 1 without encountering major deviations. The inclusion of these studies allowed the creation of some extra harmonized variables, such as verbal fluency, depression, emotional/psychiatric problems, cataracts and hip fracture, for some studies.
