Abstract
Cross-national comparisons are increasingly being used to re-evaluate whether our theories of aging are dependent on sociocultural context and to develop new insights into both long-standing and emerging issues in aging. The papers in this symposium use harmonized data from the Gateway to Global Aging to examine a range of topics in aging and provide new insights into key questions in aging research. Liu et al., determine whether social relationships mediate the association between early life adversity and later life health and well-being using longitudinal data from the U.S. and England. Considering multiple domains of the social determinants of health, such as socioeconomic status, social relationships, and health care access, Cho et al. identify which are related to self-rated health in China, Japan, and South Korea. Cheng et al. test the age-as-leveler hypothesis for explaining how socioeconomic differentials in health change in older ages in China and 19 European countries to determine if the protective effect of socioeconomic status on multi-morbidity changes with age. Harmonized data facilitate international comparisons papers, but additional efforts are sometimes needed to calibrate specific measures across international surveys. A major challenge in cross-national aging research, for instance, has been the limited ability to compare cognition across countries. Nichols and colleagues present a novel method for cocalibration of cognitive function across the U.S., England, and India that could be used for additional cross-national comparative research. The papers in this symposium demonstrate both the potential and challenges of cross-national studies of health and well-being among older adults.
