OBJECTIVES: The objective of this study was to examine the impact of obesity on one’s physical and mental health, healthcare costs and satisfaction with their healthcare. We hypothesized that obese respondents would report worse physical and mental health, higher medical costs and poorer satisfaction with their healthcare than patients without a diagnosis of obesity. METHODS: A representative (U.S.) sample of 5,000 adults completed an online survey regarding their health and healthcare. We compared respondents who were previously diagnosed with obesity to those who were not. We conducted bivariate analyses and multivariate logistic regression to assess the relationship between obesity and the outcomes of interest. RESULTS:
