There is clear evidence of causal links between specific forms of behaviour and the improvement or deterioration of health states. Unless human behaviour can be influenced, there can be no progress in promoting health, preventing disease and alleviating suffering. This book is an important contribution to the understanding of the relationship between health and behaviour. Topics have been selected for expert review on the basis of their intrinsic importance and also their relative neglect in the published literature. They cover all stages of the life cycle and a range of social and cultural settings. Health workers and behavioural scientists, particularly those working in the fields of mental health, human development and community medicine, will find this a stimulating and informative work of direct relevance to their practice.
