This textbook in the Illustrated Colour Text series offers an integrated treatment of sociology and psychology for medical students. It is presented in a much more colourful and graphic format than is usual for books on these two subjects. This integration reflects the tendency to teach these two subjects together as "behavioural science", with an increased stress on the place of medicine in society, and on illness as a product of psychological and social circumstances rather than merely a biological phenomenon. The book reflects these trends and has been successful and popular with students. New double page spreads on the following - Theories/models of health and illness, introducing the bio-psycho-social model Fetal/infant/childhood development and risk factors for ill health in middle age, including the Barker hypothesis International health
