The American Journal of Public Health is a monthly publication of the American Public Health Association. The mission of the Journal, which began publication in 1911 as a continuation of the American Journal of Public Hygiene, is to advance public health research, policy, practice, and education worldwide. Regularly published in its pages are scientific papers, authoritative editorials and commentaries, policy analyses, reports on ethical controversies, historical papers, program evaluations, and in-depth essays and reviews. Only 20 percent of submitted research papers are eventually published, and scientific papers undergo rigorous peer review. Readers of the journal include researchers, administrators, planners, physicians, dentists, nurses, scientists, educators, allied health professionals, and social workers. Continuing education credits and classified job advertisements are also offered.
