Nutritional Epidemiology

The research that involves the study of nutrition and health is said to be Nutritional Epidemiology. Diet and physical activity are arguably the most difficult exposures to assess in observational research and are plagued by considerable measurement error. In Africa and South Asia, 27−51% of women of reproductive age are underweight and it is predicted that about 130 million children will be underweighting in 2005 (21% of all children).
