<P>By tracking the distribution of disease and pinpointing relevant risk factors, social epidemiology reveals how social problems are intrinsically linked to the health of populations. The practice also takes into account the psychosocial, biological, and medical determinants of disease and health, encouraging a rich and multidisciplinary approach to analyzing and solving complex contemporary social issues. </P><P>This book provides a clear and comprehensive set of tools for practice. Julie Cwikel begins with an overview of the historical roots of public health and social medicine and shows how they formed the theoretical basis for current social epidemiological methods. Cwikel then explains the theoretical and programmatic tools social epidemiologists use in their research, program planning, and evaluation. In conclusion, Cwikel demonstrates how the SOCEPID model can be applied to a range of topics, including chronic illness, obesity, violence prevention, occupational health, sexually transmitted diseases (especially HIV), environmental hazards, and addressing the needs of vulnerable populations such as immigrants and trafficked women.</P><P>With compelling authority, Cwikel shows readers how the exciting and growing field of social epidemiology is both practical and activist, drawing on cutting-edge empirical findings to conduct policymaking research and promote health at both the personal and population levels.</P>
