The findings appear to contradict the belief that such teasing might motivate youth to change their behaviour and attempt to lose weight.
The study was conducted by Natasha A. Schvey, Ph.D., of the Uniformed Services University of the Health Sciences in Bethesda, MD, and colleagues at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development and National Institute of Diabetes and Digestive and Kidney Diseases. It appears in Pediatric Obesity.
The study involved 110 youth who were an average of 11.8 years of age when they enrolled. The participants were either overweight (defined as a body mass index above the 85th percentile) when they began the study or had two parents who were overweight or obese.
At enrolment, they completed a six-item questionnaire on whether they had been teased about their weight. They then participated in annual follow-up visits for the next 15 years.
The researchers found that youth experiencing high levels of teasing gained an average of .20 kg (.44 pounds) per year more than those who did not. The authors theorise that weight-associated stigma may have made youths more likely to engage in unhealthy behaviours, such as binge eating and avoiding exercise.
Another possible explanation is that the stress of being teased could stimulate the release of the hormone cortisol, which may lead to weight gain.
