General description
SAGE is a dataset of individuals aged 50 years and older, with a smaller sample of adults aged 18–49. Participants are from China, Ghana, India, Mexico, Russian Federation, and South Africa.
Variable categories
- Sociodemographic and economic (sex, age, marital status, living arrangements, educational level, occupation, age at retirement);
- Physical functioning (activities of Daily Living - ADL, Instrumental Activities of Daily Living - IADL, mobility);
- Overall self-report of health and mental state (self-reported health, cognition/memory, depression, sleep, loneliness);
- Health examinations: measured blood pressure;
- Physical and mental performance tests (normal-pace walking test, grip strength, cognition/memory tests);
- Risk factors (body mass index - BMI, tobacco consumption, alcohol consumption, physical activity);
- Chronic conditions (self-reported chronic conditions, disease treatment);
- Social network (social network index);
- subjective well-being (quality of life, life satisfaction, well-being).
This dataset harmonized the following databases: CHARLS, ELSA, HRS, LASI and SHARE. See a variable list for each database here.
Limitations
- The harmonization of these data sources facilitates comparisons across each study. However, the interpretation of longitudinal findings should always be framed having in mind the limitations of the ex-post harmonization exercise. The variables included in the domains for the harmonized dataset may not be as detailed as those that would be available in the individual datasets.
