The overall objective of this course will be to provide students with a critical understanding of theoretical and practical considerations in the conduct of epidemiologic research related to nutrition. The focus will be on studies of the role of diet and nutrition in chronic disease (as opposed to food-borne infectious disease outbreaks and associated issues). The material will have a strong methodological emphasis, and is intended for graduate students with an interest in understanding how epidemiologic studies of diet and chronic disease are conducted. Specifically, students will be expected to gain a critical understanding of the design, conduct, analysis and interpretation of nutritional epidemiologic studies, including the usual methods applied for assessment of this exposure, familiarity with methodological issues related to nutritional epidemiologic studies such as the appropriateness of various study designs for specific research questions, and issues regarding data analysis and interpretation.
