Abstract: Abstract Our research investigates the relationship between self-rated health (SRH) and mortality among the Chinese oldest old (age range 80–105) as well as risk patterns by gender. We use data for 7,783 respondents from the Chinese Longitudinal Healthy Longevity Study (CLHLS) conducted in 1998, 2000 and 2002. The results of a Cox Hazard Model show that self-rated health was significantly associated with mortality in the oldest old even when socio-demographic characteristics, physical and cognitive functioning, serious illness and engagement in activity were controlled. The association between SRH and the risk of mortality was stronger for males than for females. The modifying effects of some confounders on such relationships also differed by gender. Missing values on SRH predicted higher mortality, but such effects were explained by physical and cognitive functioning.
