It also documents how social injustice affects specific areas of public health, including medical care, communicable diseases, nutrition, noncommunicable diseases, mental health, violence, war, environmental health, occupational health and safety, oral health, and global health. In its last section, it provides a detailed agenda for action, including addressing social injustice in a human rights context; promoting social justice through public health policy, public health practice, and education in public health; strengthening communities; performing critical research; protecting human rights through international and national law; learning from the social movements of the 1960s; and promoting health with equitable and sustainable human development.
