As more people worldwide live in cities, increasingly we need to understand how cities and city living affect population health. Does city living negatively affect health? Conversely, can city living enhance population health and well-being? Over forty experts from around the world bring a depth of ideas to the Handbook of Urban Health, making the Handbook a focused resource for a range of health disciplines. The Handbook presents: (1) A discussion of the health of specific urban populations, among them immigrants, children, the elderly, racial and sexual minorities, the homeless, and the poor. (2) Methods relevant to the study of urban health including epidemiology, research methods, funding and policy issues, urban planning. (3) Practical issues for developing healthy cities including interventions, preventive strategies, providing health services, and teaching urban health. (4) International perspectives from developing countries and the World Health Organization. (5) Integrative chapters that conclude each of the books sections, bringing together theoretical models with the big picture. A unique professional idea book, research resource, and teaching text, the Handbook of Urban Health challenges readers to consider the role that cities play in shaping population health and to generate solutions that can make cities healthier places for all those who live there.
