5. Surrogate data? Self-reported health - a strong predictor of subsequent mortality. (Burström and Friedlund 2001, McGee et al. (1999) Heistaro et al. (2001) Helwig-Larson et al. (2003) Franks et al. (2003), Singh and Siahpush (2001) The relationship for men is different from that for women. Socioeconomic factors are important in explaining mortality variation across groups but self-reported health status still has a significant influence after controlling for them. There is variation between racial/ethnic groups in the self-reported health-mortality link but it is not huge. There is an important influence of immigrant generation with the first generation having better self-reported health and mortality than subsequent generations.

Estimate mortality rates by age and sex for ethnic groups from estimated SMRs: M i exg = M i xg × SMR i eg / 100 We assume each ethnic group has the same mortality pattern by age Adjust the estimated mortality rates so that they agree with the all group mortality rates.
