A school-based randomized controlled field trial to improve Beliefs About Obese Persons (BAOP) and Attitudes Towards Obese Persons (ATOP) among adolescents.

Objectives: A negative attitude towards obesity may lead to stigma and thus lower self-esteem in people with obesity of any society. The purpose of this study was to assess the impact of a school-based randomized controlled field trial on female adolescents' attitudes and beliefs towards people with obesity.

Methods: This experimental study was conducted among 124 middle school students (control group=62, intervention group=62). Using a cluster random sampling method, four schools were chosen and randomly assigned to intervention and control groups. The data collection tool was the Attitudes Toward Obese Persons (ATOP) and Beliefs About Obese Persons (BAOP) scales, which were used after validity and reliability processes. The intervention program was developed and implemented following pretest, responses analysis, and educational needs assessment in two sessions (180 min). The follow-ups were performed immediately and two months after the intervention. Data were analyzed by SPSS version 16.0 using independent t-test, chi-square test, repeated measures ANOVA, and ANCOVA at the significance level of 0.05.

Results: The mean BAOP scores of each group before, immediately and two months after the intervention were significantly different between (p<0.001). There was no significant difference between the mean ATOP and BAOP scores of the two groups before, immediately, and two months after the intervention (p>0.001).

Conclusions: It seems that beliefs and attitudes regarding obesity as well as discriminatory perceptions towards people with obesity have high firmness and resistance and require innovative and appropriate interventions.
