Pooled analysis of studies on DNA adducts and dietary vitamins.

Objectives: There is some evidence that dietary components that are rich in antioxidant and vitamins are inversely associated with DNA adduct levels induced by environmental carcinogens such as polycyclic aromatic hydrocarbons, although the epidemiologic data are inconsistent. This study addresses the association between vitamins, DNA adducts and smoking.

Methods: A combined analysis of individual data on the association between bulky DNA adducts and dietary vitamins was conducted.

Comparison of knowledge and attitudes toward cancer among African Americans.

Background: It has been noted that the African American population in the U.S. bears disproportionately higher cancer morbidity and mortality rates than any racial and ethnic group for most major cancers.
