Public Beliefs About Obesity Relative to Other Major Health Risks: Representative Cross-Sectional Surveys in the USA, the UK, and Germany.

Abstract

Overweight and obesity are among the leading risk factors for death worldwide. Scientists believe that the increase in obesity is primarily due to environmental changes and thus favor obesity prevention measures targeting the environment. However, it is less clear what lay people perceive as causes of obesity, and which measures they deem acceptable and promising in fighting it. This article compares lay beliefs about obesity with beliefs about other major health risks sharing certain similarities with obesity (alcohol and tobacco dependence, depression) in three countries with high obesity rates. Computer-assisted face-to-face interviews with representative samples in the UK (N = 1,216) and Germany (N = 973) and an online survey in the USA (N = 982) tapping beliefs about locus of responsibility, liability for treatment costs, and effectiveness of policy measures. In each country, respondents attributed responsibility for obesity primarily to the individual; the same pattern emerged for alcohol and tobacco dependence, but not for depression (ps < .01). The higher the attribution of personal responsibility, the more strongly respondents endorsed individual liability for treatment costs (ps < .01). Respondents judged information and fiscal policies as most and least effective, respectively, in obesity prevention. Respondents' views about obesity are similar to those about addictions; however, they regard fiscal and regulatory policies as less effective for obesity than for addictions. Raising awareness about environmental drivers of obesity and framing policy measures by reference to the fight against tobacco and alcohol could increase public support of obesity-targeted policies.
