The article comments on the public health promotion policy in the U.S. proposed by J. B. Richmond and M. Kotelchuck in their paper titled "Coordination and Development of Strategies and Policy for Public Health Promotion in the United States," that was published in the book "Oxford Textbook of Public Health."
