LGB prevalence in schools is associated with unhealthy weight-control behaviors in lesbian, gay, and bisexual youth: a multilevel analysis

Background Previous studies have found that a school climate of more heteronormativity is associated with adverse effects on the mental health of LGB students. Accordingly, our aim was to assess the association between lower LGB prevalence in schools and unhealthy weight-control behaviors among LGB youth. Methods A cross-sectional, multilevel study based in public high schools in the city of Olinda, Northeast Brazil. A multilevel logistic regression was performed, including 2500 adolescents enrolled in 27 schools. The contextual variable was the prevalence of LGB youth in each school (as a proxy for heteronormativity in schools), while the outcome was unhealthy weight-control behaviors (fasting, purging, and taking diet pills). We controlled for socioeconomic characteristics (age, sex, receiving a family allowance), obesity, and self-reported happiness. Results Lower LGB prevalence in schools was associated with higher odds of engaging in unhealthy weight-control behaviors (OR: 1.5, 95%CI: 1.0, 2.2) among all youth, regardless of sexual orientation. No cross-level interactions between school context and individual characteristics were statistically significant. Conclusion Lower LGB prevalence in schools was associated with a higher risk of unhealthy weight-control behaviors in youth regardless of sexual orientation, which may reflect either the contextual influence of school climate, or may be due to residual confounding.

Self-Perception and Self-Acceptance Are Related to Unhealthy Weight Control Behaviors in Catalan Adolescents: A Cross-Sectional Study

Adolescence is associated with a higher vulnerability that may result in a high dissatisfaction, the practice of unhealthy weight-control behaviors (UWCB) and, eventually, the onset of body image-related mental disorders. These factors are strongly associated with the social context, so it is important to characterize them in local or regional studies. To assess the relationship between body image and UWCB presence, a cross-sectional study was performed among 2496 schooled adolescents from Lleida (Spain) between 2017 and 2019. Their perceived and desired images were evaluated and compared with the real image in order to obtain the body distortion and the body dissatisfaction and relate them with UWCB. The studied individuals perceived themselves thinner than they actually were, with no differences between males and females. However, differences were found regarding body dissatisfaction, showing that females desired to be thinner, while males desired a more corpulent body image. Furthermore, one out of ten individuals reported UWCB, with higher prevalence among females. UWCB was associated with a desire to be thinner and with distorted body images. It is essential to work on self-perception and self-acceptance in early adolescence from an interdisciplinary perspective at educational, social and health levels to promote health in adolescence.

Factors Associated With Unhealthy Weight Control Behaviors Among a Representative Sample of U.S. High School Students

Adolescents often practice unhealthy behaviors to lose weight or keep from gaining weight. Centers for Disease Control and Prevention has conducted biennial Youth Risk Behavior Survey (YRBS) of various health risk behaviors since 1991 using U.S. representative samples of high school students and is therefore best for us to identify risk/preventive factors associated with unhealthy weight control behaviors (UWCB). We quantitatively assessed the association between various health risk behaviors with UWCB by gender using YRBS data. Due to the absence of UWCB items since 2015, we analyzed the latest (2013) data using binary multiple logistic regression. Among the 13,583 participants, 22.7% of girls and 10.1% of boys engaged in UWCB. Among girls and boys separately, the common significant factors included suicidal behaviors, alcohol drinking, misused prescription drug, feeling depressed, skipping breakfast, and attending physical education class. School nurses are suggested to have knowledge about the aforementioned risk factors and provide assessment, consultation, and education to help reduce UWCB.

The prevalence of weight-control behaviors and associated factors among adolescent girls in Tehran

ObjectivesWeight control behavior is a strategy for weight loss or weight gains that range from healthy to unhealthy. This study is aimed to determine the prevalence of weight control behaviors and their related factors in adolescent girls in Tehran.MethodsAdolescent girls in the last grade of high school (n=491) that were selected by a multi-stage sampling method completed a cross-sectional survey (2018) in Tehran city in Iran. Data were collected using questionnaires (standard and researcher-made) by the self-report method and analyzed using descriptive and inferential statistics, including Chi-square, independent t-test, and logistic regression.Results17.5% of adolescents had healthy, 60.6% had unhealthy, 15.8% had extreme unhealthy weight control behaviors, and 6.1% had no weight control behaviors. 74.8% of adolescents were in the normal body mass index (BMI) percentile. Unhealthy weight control behaviors were observed more than healthy behaviors at all BMI levels. Weight control behaviors had significant relationships with weight control intention (p=0.005), family (p=0.016) and peers (p=0.011) encouragement to weight control, engagement of relatives in weight control behaviors (p=0.016), anxiety (p<0.001), and age (p=0.030). BMI has a positive correlation with body weight satisfaction (p<0.001) and body weight perception (p<0.001). The results of logistic regression showed that increasing anxiety score can increase the possibility of engaging in unhealthy weight control behaviors (odd ratio=1.086, p=0.006).ConclusionsConsidering that a significant percentage of adolescents have unhealthy and extreme unhealthy weight control behaviors, and some of these behaviors leave irreversible effects on the health of this age group, design, and implementation of educational programs to prevent such behaviors seem imperative.

Heteronormativity in schools is associated with unhealthy weight-control behaviors in Lesbian, Gay, and Bisexual youth: A multilevel analysis.

Background Previous studies found that a school climate of more heteronormativity is associated with adverse effects on the mental health of LGB students. Accordingly, our aim was to assess the association between low LGB visibility in schools and unhealthy weight-control behaviors among LGB youth. Methods Cross-sectional, multilevel study based in public high schools in the city of Olinda, Northeast Brazil. A multilevel logistic regression was performed, including 2,500 adolescents enrolled in 27 schools. The contextual variable was the prevalence of LGB youth in each school (as a proxy for heteronormativity in schools) while the outcome was unhealthy weight-control behaviors (fasting, purging, and taking diet pills). We controlled for socioeconomic characteristics (age, gender, receiving a family allowance), obesity, and self-reported happiness. Results Low LGB visibility in schools was associated with higher odds of engaging in unhealthy weight-control behaviors (OR: 1.5, 95%CI: 1.0, 2.2) among all youth, regardless of sexual orientation. Among LGB youth, there was some suggestion that the association between LGB visibility and unhealthy weight control behaviors was mediated by experiences of victimization and self-perceptions of unhappiness. Conclusion A school environment of low LGB visibility was associated with unhealthy weight-control behaviors in youth.
