Blood collection following nonstandard operations largely increases the risks of infectious diseases through cross-contamination. Commercial plasma donation and the resulting HIV/AIDS and hepatitis C epidemics in central China in the 1990s killed more than one million people. Many blood banks...

Background: Blood collection following nonstandard operations largely increases the risks of infectious diseases through cross-contamination. Commercial plasma donation and the resulting HIV/AIDS and hepatitis C epidemics in central China in the 1990s killed more than one million people. Many...

This paper reviews the latest evidence of the effects of early life circumstances on old-age health, distinguishing in utero exposures from childhood exposures to a wide range of environments. We then leverage the growing number of studies of the impact of the Great Chinese Famine (1959-1961) on...

Flint changed its public water source in 2014, causing severe water contamination. We estimate the effect of in utero exposure to polluted water on health at birth using the recent Flint water crisis as a natural experiment. Matching vital statistics birth records with various sources of data,...

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...
