Dietary cholesterol and lung cancer risk among men in Hawaii

Preliminary analysis of dietary data collected from 188 male subjects with lung cancer and 294 controls, in an ongoing population-based case-control study in Hawaii, indicate that dietary cholesterol is positively and significantly associated with lung cancer risk after statistically adjusting for age, ethnicity, pack-years of cigarette smoking, and occupational exposure to lung carcinogens. The increased lung cancer risk associated with high dietary cholesterol appears to be consistent in all five major ethnic groups in Hawaii.
