Abstract:
|
Obesity/overweight (Ob/Ow) are associated with several chronic diseases. In the 1980--90s prevalence of obesity increased in the US. Researchers tried to determine the impact of Ob/Ow on mortality by estimating the number of deaths associated with body weight. Questions were raised about the methodology of these estimates. In response CDC and NCI investigators developed a methodology based on estimating attributable risk with accounting for confounding in order to carry out the estimation. These investigations used data from the National Health and Nutrition Examination Surveys (NHANES) I,II,III and their mortality follow-up along with prevalences of Ob/Ow and confounders from current NHANES and #s of deaths from Vital Statistics. These estimates have been used to establish the impact of Ob/Ow on mortality. The statistical methodology, results and sensitivity analysis will be presented.
