Association of lipids and lipoprotein level with total mortality and mortality caused by cardiovascular and cancer diseases (Poland and United States collaborative study on cardiovascular epidemiology).
This study evaluates the relation between total serum cholesterol, triglycerides, and high-density lipoprotein (HDL) cholesterol, and subsequent total, cardiovascular, and cancer mortality. These data are from 4,946 US and 5,198 Polish men and women aged 35 to 64 years at baseline with mortality follow-up over 13 years. Total cholesterol showed a U-shaped or J-shaped relation to age-adjusted total and cancer mortality across all samples, with significance only in Polish women. The multivariable adjusted relative risk for total and cancer mortality was higher in the lowest cholesterol category only in Poland and significant only for cancer. Cardiovascular mortality was positively related to cholesterol, but only in Polish men and US women was mortality significantly higher in the highest versus the lowest cholesterol category. The multivariable adjusted relative risk of cardiovascular death was greater in the highest versus the lowest cholesterol category, but this trend was significant only in the US. HDL cholesterol was inversely related to total (significant only in US men) and cardiovascular mortality (significant only in US and Polish men). A similar, but not significant, association of HDL cholesterol was found with cancer mortality. The multivariable adjusted relative risk of total mortality was inversely related to HDL cholesterol significant in both the US and Poland. The relative risk of cardiovascular mortality was significantly lower at higher HDL cholesterol levels in all samples. The relative risk of cancer mortality was highest and significant at the lowest HDL cholesterol level in the US and Poland. Elevated triglycerides were associated with increased risk of total and cardiovascular mortality, but this trend was significant only in the US. Cancer mortality was not significantly related to triglycerides. The present study indicates that in geographically and culturally diverse populations, the relation of lipids with cardiovascular mortality is similar. The relation with total and cancer mortality varies by country, gender, and lipids. This suggests that relations of total and cancer mortality with lipids or lipoproteins are weaker than associations with cardiovascular mortality.
