This chapter begins by discussing the strengths and limitations of various dietary assessment methods—24-hour recall, food records, diet history, food-frequency questionnaires (FFQs), and biomarkers—and their validity and applications in obesity epidemiologic research. It then considers the assessment of, and adjustment for, total energy intake in epidemiologic research. It discusses methods to correct for random and systematic measurement errors in nutritional epidemiologic studies. Finally, the chapter reviews statistical approaches for assessing the impact of overall diet through dietary patterning analyses.

Keywords:   obesity research, obesity epidemiological studies, dietary composition, food-frequency questionnaires
