Estimating utility values for health states of overweight and obese individuals using the SF-36

Abstract

Objective: To use health-related quality-of-life (HRQoL) data from the Australian 1995 National Health Survey to estimate the impact of obesity (as measured by body mass index or BMI) on utility and quality-adjusted life expectancy (QALE). Method: SF-36 responses from 12,661 individuals in the general population were transformed into utility values using the SF-6D algorithm developed by Brazier and colleagues. Separate regression analyses for males and females were used to examine the impact of BMI and five obesity-related medical conditions (diabetes, coronary heart disease, depression, musculoskeletal disorders, and cancer) on utility. The utility estimates were used to provide indicative ..
