Effects of sociodemographic variables on adult mortality in the united states: comparisons by sex, age, and cause of death

摘要

The effects of sociodemographic variables on mortality for U>S. adults are estimated, using data from the National Health Interview Survey matched with National Death Index data. Depentent variables of the proportional hazards models include all-cause mortality and mortality due to circulatory disease, lung cancer, breast cancer, other cancer, other medical causes, and nonmedical causes. Results indicate that all of the sociodemographic variables (edu- cation, income, employment status, marital status, race) have independent effects on all-cause mortality, with similar-effect sizes for males and females, and weaker effects in the older group (ages 65+) than the younger (ages 25-64). For the separate causes of death, the effects of most sociodemographic variables vary by sex.
