This chapter reviews analytic epidemiologic study designs and research into the consequences and determinants of obesity. These include ecological studies, cross-sectional studies, case-control studies, and cohort studies. It argues that prospective cohort studies, in which exposure is assessed before the occurrence of disease, minimize risk of bias from retrospective reporting on diet and lifestyle factors, and are generally considered the strongest nonrandomized design. For this reason, results from prospective studies with detailed exposure assessment should be given more weight than findings from other analytic epidemiologic studies in the evaluation of evidence.

Keywords:   epidemiologic studies, ecological studies, cross-sectional studies, case-control studies, cohort studies, obesity studies
