Abstract

SUMMARY:

This study examined prospectively the association of baseline plasma HDL-cholesterol levels with incidence of lung cancer in 14,547 members of the Atherosclerosis Risk in Communities (ARIC) cohort. There were 259 cases of incident lung cancer identified during follow-up from 1987 through 2000. Results of this study indicated a relatively weak inverse association of HDL-cholesterol with lung cancer that was dependent on smoking status. The hazard ratio of lung cancer incidence in relation to low HDL-cholesterol, adjusted for race, gender, exercise, alcohol consumption, body mass index, triglycerides, age, and cigarette pack-years of smoking, was 1.45 (95% confidence interval 1.10, 1.92). This association was observed among former smokers (hazard ratio: 1.77, 95% confidence interval 1.05, 2.97), but not current smokers. The number of cases among never smokers in this study was too small (n=13) for meaningful interpretation of effect estimates. Excluding cases occurring within 5 years of baseline did not appreciably change the point estimates, suggesting lack of reverse causality. The modest association of low plasma HDL-cholesterol with greater incident lung cancer observed in this study is in agreement with existing case-control studies.
