Design Concepts in Nutritional Epidemiology

Bol Partner

Design Concepts in Nutritional Epidemiology 2nd edition presents the latest methods for examining the complex relationship between diet and disease. The first edition has been completely revised to include the most recent advances in methodological design. Also included are several new chapters on areas of recent interest and significance. In examining the relationship between nutritional exposure and disease aetiology, the importance of a carefully considered experimental design cannot be overstated. A sound experimental design involves the formulation of a clear research hypothesis and the identification of appropriate measures of exposure and outcome. It is essential that these variables can be measured with a minimum of error, whilst taking into account the effects of chance and bias, and being aware of the risk of confounding variables. The first edition of Design Concepts in Nutritional Epidemiology presented a throrough guide to research methods in nutritional epidemiology. Since publication of the 1st edition, we now have a much better understanding of the characteristics of nutritional exposure that need to be measured in order to answer questions about diet-disease relationships. The 2nd edition has been extensively revised to include the most up-to-date methods of researching this relationship. Included are new chapters on qualitative and sociological measures, anthropometric measures, gene-nutrient interactions, and cross-sectional studies. Design Concepts in Nutritional Epidemiology will be an essential text for nutritionists and epidemiologists, helping them in their quest to improve the quality of information upon which important public health decisions are made.

This book focuses on the key issues of design and analysis in studies which aim to relate measures of nutritional exposure to disease outcome. The first section discusses how to identify the appropriate measures of exposure and outcome in order to formulate a clear research hypothesis, including the question of power and sample size. This is followed by a detailed discussion of how to measure the exposures and outcomes with a desired degree of accuracy. Particular emphasis is placed on the identification of measurement error and confounding factors, and how to cope with their influence on the observed relationships. The final section addresses the problem of design and interpretation that arise in epidemiological studies - ecological, case control, cohort, and experimental - which include measures of nutritional exposure. The need for this book arises because of the complexity of nutritional exposures. By learning how to identify relevant measures of nutritional exposure and measure them correctly in epidemiological studies, we improve our ability to assess the role of nutrition in disease etiology.
