Childhood socioeconomic circumstances, social status, and health in older age: Are they related in China?

It is well known that in western countries, people with disadvantaged socioeconomic circumstances during childhood are at a significantly higher risk of ill health in older age. This study further questions whether in China, individuals' different childhood socioeconomic circumstances and social status continue to affect their life-long health. Furthermore, do later-life socioeconomic circumstances affect health so that childhood conditions no longer play a significant role? The influence of social mobility and accumulation was also tested. The analysis was based on the China Health and Retirement Longitudinal Study (CHARLS) 2013 and CHARLS life history survey. Health outcomes were measured based on self-reported health, disability for activities of daily life, depression symptoms, and cognitive impairment. In addition to measurements of childhood, the analysis included current socioeconomic circumstances, current health behaviors, and demographic characteristics. Using ordered logit or logit and Ordinary Least Square (OLS) regression models, the study shows the existence of the association between childhood conditions and later health in China. After adjusting for current socioeconomic circumstances, social status was no longer related to later health. However, childhood socioeconomic circumstances still significantly influenced health at a later age. Advantaged socioeconomic circumstances in the life course (high stability) provided the best protection for later health. However, moving downward-that is, experiencing childhood socioeconomic advantage but later-life socioeconomic disadvantage-was the most detrimental to later health. Overall, this study provides new evidence from China to support the notion that health in older age is related to dynamic processes structured by the social stratification system. Thus, this study emphasizes an integrated health policy based on the premise of maximizing health over the entire life course.
