This document discusses the role of cultural factors in health and disease. It outlines 6 key areas where culture impacts health: concepts of disease etiology and cure, environmental sanitation, food habits, mother and child health, personal hygiene, and sex and marriage. Across these domains, certain cultural customs and beliefs can promote the spread of disease by preventing proper treatment or sanitation practices, and can influence health behaviors around nutrition, hygiene, and family planning. Overcoming cultural barriers is important for implementing effective national health programs.
