Major Risk Factors for Cardiovascular Disease Mortality in Adults: Results from the Nutrition Canada Survey Cohort

Abstract

The cardiovascular mortality experience of over 7000 Canadians ages 35–79 years free of self-reported heart disease or stroke who participated in the Nutrition Canada survey is presented. The effects of various risk factors on cardiovascular disease mortality were assessed using multlvarlate Poisson regression analyses. Factors associated with a significantly increased risk of dying included cigarette smoking, hypertension, diabetes and, for women, serum cholesterol. Relative risks were similar for those ages 36–64 years compared to those 65–79 years for diabetes but were higher among those 35–64 years for cigarette smoking, dlastolic hypertension, obesity and serum cholesterol (females only). Individuals drinking three or more drinks daily had a relative risk of 3.18 for stroke. Population attributable risks for smoking, hypertension, elevated serum cholesterol and diabetes, respectively, were 47%, 21%, 7% and 8% for men and 10% 21% 18% and 16% for women.
