Plain language summary
Obesity is a global health issue due to its association with many chronic diseases, including type 2 diabetes, cardiovascular disease and certain cancers. Stigmatisation and discrimination against people with obesity has increased over the past few decades. According to the “Theory of class” a person’s “habitus”, that is their general attitude, lifestyle and even body shape, can be seen as a metaphor for social status. The aim of this systematic review of 17 studies was to investigate whether socioeconomic status is associated with “weight bias”, that is stigmatising and discriminating attitudes towards people with obesity. 11 of the 17 studies found a significant association between educational attainment and/or income with stigmatising and/or discriminatory attitudes, but results were mixed, with some studies showing that people with higher education and/or income level were more likely to display stigmatising and/or discriminating attitudes, whilst other studies showed the opposite. The authors conclude that the findings have to be discussed in the cultural context, including cultural and governmental differences.
Abstract
OBJECTIVES Obesity is considered a global health issue, because of its health-related consequences and also because of its impact on social status as a result of stigma. This study aims to review the quantitative state of research regarding socioeconomic characteristics' influence on weight-related stigmatisation and discrimination. Based on Bourdieu's Theory of Class and his concept of 'habitus', it is assumed that people with a higher level of education and income show stronger negative attitudes towards people with obesity. METHOD A narrative systematic literature review was conducted in 2017 using PubMed, PsychINFO, Web of Science and the Cochrane Library. Seventeen studies that measured weight bias and either educational attainment or level of income were included in the analysis. RESULTS The results of the studies included were inconsistent: six of these studies were found to support the hypothesis, whereas two of the studies contradicted it. The remaining seven studies did not show any significant correlation between weight bias and either education or income. CONCLUSION In light of the inconsistent and heterogeneous results of the studies that report a significant association between weight bias and socioeconomic variables, the findings must be discussed concerning their cultural context, that is, cultural and governmental differences. Furthermore, educational attainment seems to be more likely to predict weight bias than income. The review revealed a lack of research when it came to examining the impact of socioeconomic capital on weight bias.
