Correlates of mortality in Russian and US women. The Lipid Research Clinics Program

Associations between selected risk factors and 7-year all-cause mortality were studied in 2,187 Russian women and 2,146 US women who were screened as part of a US-Russian collaborative program. The US women were screened during the period 1972-1976, while the Russian women were screened from 1978 to 1982. Cigarette smoking and elevated systolic blood pressure were associated with increased mortality in both samples. High density lipoprotein (HDL) cholesterol was inversely related to mortality in US women, but there was no association of HDL cholesterol with mortality in Russian women. Prevalent angina and electrocardiographic abnormalities were associated with mortality in both samples, but the relations achieved statistical significance only in the Russian sample. The problems of cigarette smoking and elevated blood pressure should be addressed with public health measures in both countries. The absence of an association between HDL cholesterol and mortality in the Russian sample should be investigated further.
