Analyses of the National Health and Nutrition Examination Survey (NHANES) have suggested that the mortality rate (MR) associated with obesity has decreased over calendar time. However, there has been conflicting evidence about the apparent change in the obesity-MR over calendar time. This dissertation investigates some of the empirical and methodological issues involved in assessing the longitudinal change in the obesity-mortality associations. In the first manuscript, Obesity and Mortality: Are the Risks Declining? Evidence from Multiple Prospective Studies in the U.S., a multiple longitudinal design is proposed and implemented to evaluate whether the obesity-mortality associations have declined over calendar time after …

Self-care is a major component of heart failure management. Excess weight is a disease that may negatively affect a patient's ability to effectively practice self-care. The project aimed to assess 1) the relationship between weight status and heart failure self-care behaviors and 2) the modification of the relationship between social support and heart failure self-care by weight status. This cross sectional study utilized baseline data from a cohort of African-American and Caucasian participants diagnosed with heart failure. The heart failure cohort was formed from three larger studies (n=690) designed to assess the relationships among social support, self-care behaviors and hospital …
