Which organization is NOT listed among the national Medical Associations?

• A. JAMA
• B. CMAJ
• C. NIH
• D. WHO

Answer: (C)

National medical associations are professional bodies that unite physicians within a country and often publish journals, set ethical norms, and advocate for physicians’ interests. JAMA is the Journal of the American Medical Association, tied to the American Medical Association, which is the United States’ national medical association. CMAJ is the Canadian Medical Association Journal, linked to Canada’s national medical association. WHO operates on a global scale as an international health organization, not a national association. The NIH, meanwhile, is a U.S. government research agency focused on biomedical and public health research, not a professional physician association. So NIH is not a national medical association.
