Weight stigma among adolescents in three low- and middle-income countries

Abstract

Background: Overweight (OW) and obesity affect millions of adolescents worldwide. Evidence from high-income countries indicates widespread weight stigma that adversely affects young people's mental and physical health. However, evidence relating to low- and middle-income countries (LMICs) is sparse. We aimed to generate insight into weight stigma prevalence and experience among adolescents in three LMICs.

Methods: We identified adolescents aged 15-19 from Brazil, South Africa, and Indonesia from families within market research databases. We adopted a mixed-methods design. The sample included equal numbers by country, sex, and age, and included urban and rural dwellers. Self-reported weight was recorded but was not a selection criterion. Consent (age >18) and assent/parental consent (<age 18) were obtained. In-depth interviews (n = 18) informed the survey design. We used a computer-assisted telephonic interviewing survey (n = 1200) to assess weight stigma prevalence and experience. We conducted a qualitative thematic data analysis and used SPSS-23 for quantitative data.

Results: Many adolescents affected by OW and some affected by underweight (UW) had experienced weight stigma and expressed negative perceptions of their weight. Negative perceptions were expressed the most by those affected by OW, followed by those affected by UW, and then those of healthy weight (HW). Weight stigma and weight dissatisfaction were highest in Brazil and South Africa, and lower in Indonesia. More young women experienced weight stigma, yet this was also common among young men. One in five of all participants reported negative impacts, predominantly on mental health, and regarding weight management and healthy behaviours. Young people recommended measures to address weight stigma, promote an inclusive model of health and body image, and better support to achieve and maintain a HW.

Conclusions: Weight stigma adversely affects sizeable numbers of adolescents in LMICs, particularly those affected by OW. Addressing this is essential to protect adolescent (and future adult) mental and physical health.
