Abstract and Keywords
Public health social work is based on an epidemiologic approach to preventing, addressing, and solving social health problems. It originated in the early 20th century, drawing upon both social work and public health theories, frameworks, research, and practice. Public health social work is characterized by an emphasis on prevention and health promotion. The field has evolved to become multi-method and interdisciplinary, making it particularly relevant to 21st century practice. Widespread changes on both domestic and international fronts—such as globalization, increased migration, natural and man-made disasters, persistent chronic diseases, and resulting health disparities—are examples of current challenges that benefit from a public health social work approach.
