Vitamin, Mineral, and Multivitamin Supplements to Prevent Cardiovascular Disease and Cancer: Recommendations From the U.S. Preventive Services Task Force
Cet article présente les recommandations d'un groupe d'experts américains ("U.S. Preventive Services Task Force") sur la supplémentation en vitamines et minéraux pour réduire le risque de cancer ou de maladies cardiovasculaires chez les personnes âgées de 50 ans ou plus
Who developed these recommendations ? The U.S. Preventive Services Task Force (USPSTF) developed these recommendations. The USPSTF is a group of health experts that reviews published research and makes recommendations about preventive health care.
What is the problem and what is known about it so far? Cardiovascular disease (CVD) and cancer are common problems for Americans. Shortages of antioxidant vitamins (vitamins A, C, and E;
β-carotene; and folic acid) are associated with the blood vessel changes that occur in CVD. Therefore, people have thought that taking these vitamins might decrease the chances of CVD. Information also suggests that these vitamins might decrease a person
’s chances of cancer. Many studies have examined associations between particular vitamins and CVD and cancer. The studies vary in quality, and their results often conflict. In 2003, the USPSTF recommended that people should not take
β-carotene supplements to decrease their chances of CVD or cancer. At that time, the USPSTF concluded that there was not enough known to be able to make a recommendation for or against taking vitamins A, C, or E; multivitamins with folic acid; or combinations of these vitamins for the primary purpose of preventing CVD or cancer. The USPSTF wanted to update these recommendations on the basis of information that has become available since 2003.
