[Read] Nutritional Epidemiology For Full
Online This text is intended for those who want to understand the complexities of diet and risk of major diseases, such as cancer and cardiovascular disease. It is aimed both at researchers involved in the uprising of these complex relationships and at the readers of the rapidly multiplying and often confusing scientific literature on the subject. The book starts with an overview of research strategies in nutrition epidemiology – still a relatively new discipline that combines the vast knowledge gained by nutritionists during this century with the methods developed by epidemiologists to study determinants of diseases with multiple etiologies and long latent periods. Much is devoted to methods for dietary assessment using data on food intake, biochemical indicators for diet and measures of body composition and size. The reproducibility and validity of each approach and the consequences of measurement errors are considered in detail. The analysis, presentation and interpretation of data from epidemiological studies of diet and disease are explored in depth. Special attention to the important influence of total energy intake on findings in such studies. To illustrate methodological problems in nutritional epidemiology, the relationship between dietary factors and the incidence of lung and breast cancer, heart disease and birth defects is investigated. The first edition of nutritional epidemiology, published in 1989, was well recognized and quickly established as the standard reference in this field. The second edition, published in 1998, added new chapters on the analysis and presentation of dietary data, nutritional monitoring and folic acid and neural tube defects. This new edition, in addition to the significant updating of existing chapters, includes new chapters on the assessment of physical activity, nutrition and genetic epidemiology, and the role of nutritional epidemiology in politics.
