Abstract

This paper estimates the extent to which childhood circumstances contribute to health
inequality in old age and evaluates the importance of major domains of childhood
circumstances to health inequalities in the USA and China. We link two waves of the China
Health and Retirement Longitudinal Study (CHARLS) in 2013 and 2015 with the newly
released 2014 Life History Survey (LHS), and two waves of the Health and Retirement Study
(HRS) in 2014 and 2016 with the newly released 2015 Life History Mail Survey (LHMS) in
the USA, to quantify health inequality due to childhood circumstances for which they have
little control. Using the Shapley value decomposition approach, we show that childhood
circumstances may explain 7-16 percent and 14-30 percent of health inequality in old age
in China and the USA, respectively. Specifically, the contribution of childhood circumstances
to health inequality is larger in the USA than in China for self-rated health, mental health,
and physical health. Examining domains of childhood circumstance, regional and rural/
urban status contribute more to health inequality in China, while family socioeconomic
status (SES) contributes more to health inequality in the USA. Our findings support the
value of a life course approach in identifying the key determinants of health in old age.
Distinguishing sources of health inequality and rectifying inequality due to early childhood
circumstances should be the basis of policy promoting health equity.
