Social stigma of obesity is bias or discriminatory behaviors targeted at overweight and obese individuals because of their weight and high body fat percentage. Such social stigmas can span one's entire life as long as excess weight is present, starting from a young age and lasting into adulthood. Stigmatization of obesity is usually associated with increased health risks (morbidity) of being overweight or obese and the possibility of a shorter lifespan (mortality). Fat people marry less often, experience fewer educational and career opportunities, and on average earn a lesser income than normal weight individuals. Although public support regarding disability services, civil rights, and anti-workplace discrimination laws for obese individuals have gained support across the years, overweight and obese individuals still experience discrimination, which may have detrimental implications in relation to both physiological and psychological health. These issues are compounded by the significant negative physiological effects that are already associated with obesity, which some have proposed may be caused in part by stress from the social stigma of obesity (or which may be made more pronounced as a result of that stress). Anti-fat bias refers to prejudicial assumptions that are based on an assessment of a person as being overweight or obese. It is also known as "fat shaming" or "fatphobia". Anti-fat bias can be found in many facets of society, and fat activists commonly cite examples of mass media and popular culture that pervade this phenomenon.
Characteristics Studies have indicated that experiencing weight stigma reinforces lifestyle behaviors that contribute to obesity. Individuals who are overweight or obese tend to devalue their own in-group and prefer the out-group (i.e. thinner individuals).
Prevalence Individuals who are subjected to weight-related stigma are shown to be admired less in the public eye when compared with other groups, such as sexual and gender minorities and those with mental illness. In the US, self-reported incidents of weight-based discrimination increased from 1995 to 2006. Anti-fat bias has been observed in groups hoping to become physical education instructors. In a study published in 2007, a group of 344 psychology or physical education majors at a New Zealand University were compared, and it was found that the prospective physical education teachers were more likely to display implicit anti-fat attitudes than the psychology majors. A number of studies have found that health care providers frequently have explicit and/or implicit biases against overweight people, and it has been found that overweight patients may receive lower quality care as a result of their weight. Medical professionals who specialize in the treatment of obesity have been found to have strong negative associations toward obese individuals. The stress from obesity-related stigma may also cause negative health outcomes. A 2004 study in preschool-aged children reported a preference for average-sized children over overweight children as friends. Overweight individuals often found themselves suffering repercussions in many facets of society, including legal and employment issues later in their life. According to a 2010 review of published studies, interventions seeking to reduce prejudice and social stigma against fat and obesity are largely ineffective.
