Bullying experiences, body esteem, body dissatisfaction, and the moderating role of weight status among adolescents

Analyzing body dissatisfaction and gender dysphoria in the context of minority stress among transgender adolescents

BACKGROUND

Gender dysphoria among transgender adolescents has predominantly been examined in relation to body dissatisfaction. While in adult transgender samples, body dissatisfaction is higher than in cisgender controls, this has so far rarely been investigated for adolescents. In the context of a cisnormative society, the impact of influences from the social environment on body dissatisfaction and gender dysphoria has been neglected in research. Therefore, this study aimed to (1) provide a detailed analysis of body dissatisfaction among young transgender people and (2) investigate whether body dissatisfaction and gender dysphoria are associated with experiences of minority stress such as trans hostility and poor peer relations (PPR).

METHODS

The paper presents a cross-sectional study among a sample of transgender adolescents, presenting at a specialized outpatient counseling clinic (N = 99; age M = 15.36, SD = 1.85). First, body dissatisfaction (assessed by the Body-Image-Scale; BIS), was explored and compared to data from a population-based control group of cisgender peers (N = 527; age M = 14.43, SD = 0.97). Second, within a clinic-referred transgender subsample (n = 74), associations between body dissatisfaction and gender dysphoria (measured by Utrecht Gender Dysphoria Scale; UGDS), PPR (measured by the Youth-Self-Report; YSR-R), and trans hostile experiences (assessed in clinical interview) were examined by correlations, t-tests and multivariate regression.

RESULTS

Transgender adolescents reported more body dissatisfaction than cisgender peers. The dissatisfaction with sex characteristics, non-hormonal reactive body regions and the total score for body dissatisfaction were positively related with gender dysphoria. The majority had experienced trans hostility in the present and/or past (54.1%) and PPR (63.5%). More body dissatisfaction was correlated with more PPR regarding visible body parts i.e., hair, overall appearance and muscles, whilst PPR and gender dysphoria were not associated. Transgender adolescents who experienced trans hostility showed higher gender dysphoria and PPR, but not more body dissatisfaction. In multiple regression, trans hostility predicted gender dysphoria, whilst age and PPR predicted body dissatisfaction.

DISCUSSION

Experiences of minority-stress differentially interact with body dissatisfaction and gender dysphoria among transgender adolescents. Social correlates of body dissatisfaction and gender dysphoria must be considered when working with young transgender people.

Individualized Implementation of Youth Quality of Life Instrument-Research Version (YQOL-R) Among Chinese Adolescents with Different Weight Status

Purpose

This study implemented the individualized Youth Quality of Life Instrument-Research Version (YQOL-R) to estimate the quality of life (QoL) among Chinese adolescents with three different Body Mass Index (BMI) levels. The study aims to explore and provide a reference for developing individualized QoL (IQoL) measurements in China.

Methods

The sample consisted of 822 aged 11-18 from nine schools. The data collection included all participants' primary characters (age, sex, annual household income, parental education, and recruitment community) and their self-report QoL. Precisely, based on the generic measurement of YQOL-R, we developed IQoL measurements by asking adolescents' perceived five most important things to them (IQOLimportance) and the aspects they most want to change (IQOLchange) from 19 facets, respectively. The one-way analysis of variance (ANOVA) was applied to compare total and subscale scores of IQOLimportance, IQOLchange, and YQOL-R among adolescents with three different weight status. Also, the data analysis used multivariable linear regression modeling to test the effects on scores of IQOLimportance and IQOLchange.

Results

Overall, the obese adolescents identified "Having good physical health" as the most important (54.03%) and most like-to-change (42.65%); in contrast, the normal-weight group ranked "Being myself" as the top facet of IQOLimportance (52.42%) and "Having good friends" as the top facet of IQOLchange (43.12%). The obese adolescents' reported IQOLimportance scores are significantly lower than those of the normal-weight group (P=0.039). However, there is no significant difference in IQOLchange score among the three weight-status groups. The multivariable linear regression models indicated that adolescents who are girls (P=0.035), have higher educated fathers (P=0.049), and are overweight/obese (P=0.041) self-reported worse IQOLimportance score; yet, the girls (P=0.023) and older adolescents (P=0.004) answered lower IQOLchange scores. In addition, adolescents who had higher educated mothers (P=0.047; 0.023) and responded with higher total YQOL-R scores (P<0.001; <0.001) reported higher IQOLimportance and IQOLchange scores.

Conclusion

In the current study, although the self-reported YQOL-R scores from different weight status did not present a significant difference, the obese group reported a statistical trend towards lower IQOLimportance scores than the normal-weight and overweight adolescents. These findings emphasize that IQOLimportance and IQOLchange could capture adolescents' perspectives with different weight statuses about their lives, which are unique as complementary health outcomes accompanying YQOL-R in health surveys and interventions among Chinese adolescents.

Establishing the relationships between adiposity and reproductive factors: a multivariable Mendelian randomization analysis

BACKGROUND

Few studies have investigated associations between adiposity and reproductive factors using causal methods, both of which have a number of consequences on women's health. Here we assess whether adiposity at different points in the lifecourse affects reproductive factors differently and independently, and the plausibility of the impact of reproductive factors on adiposity.

METHODS

We used genetic data from UK Biobank (273,238 women) and other consortia (EGG, GIANT, ReproGen and SSGAC) for eight reproductive factors: age at menarche, age at menopause, age at first birth, age at last birth, number of births, being parous, age first had sexual intercourse and lifetime number of sexual partners, and two adiposity traits: childhood and adulthood body size. We applied multivariable Mendelian randomization to account for genetic correlation and to estimate the causal effects of childhood and adulthood adiposity, independently of each other, on reproductive factors. Additionally, we estimated the effects of reproductive factors, independently of other relevant reproductive factors, on adulthood adiposity.

RESULTS

We found a higher childhood body size leads to an earlier age at menarche, and an earlier age at menarche leads to a higher adulthood body size. Furthermore, we find contrasting and independent effects of childhood and adulthood body size on age at first birth (beta 0.22 SD (95% confidence interval: 0.14, 0.31) vs - 2.49 (- 2.93, - 2.06) per 1 SD increase), age at last birth (0.13 (0.06,0.21) vs - 1.86 (- 2.23, - 1.48) per 1 SD increase), age at menopause (0.17 (0.09, 0.25) vs - 0.99 (- 1.39, - 0.59) per 1 SD increase), and likelihood of having children (Odds ratio 0.97 (0.95, 1.00) vs 1.20 (1.06, 1.37) per 1 SD increase).

CONCLUSIONS

Our findings demonstrate the importance of considering a lifecourse approach when investigating the inter-relationships between adiposity measures and reproductive events, as well as the use of 'age specific' genetic instruments when evaluating lifecourse hypotheses in a Mendelian randomization framework.

Unhealthy weight control behaviors and related factors by gender and weight status: Results from a nationally representative sample of Korean adolescents

Given the serious consequences of unhealthy weight control behaviors (UWCB) among adolescents, identifying factors contributing to it in this population is crucial. Although gender differences have been reported as UWCB-related factors, studies on weight status remain limited. Hence, using a nationally representative sample, we investigated the differences in UWCB-related factors by gender and weight status. Most sociodemographic, health-related behavior, psychosocial, and school factors were remarkably correlated with UWCB in the normal-weight female group; however, they demonstrated most inconsistent correlations in the overweight female group. Overall, this study suggests that UWCB-preventing interventions in adolescents should be customized by gender and weight status.

Cyberbullying victimization and disordered eating behaviors: The mediating roles of self-compassion and self-objectification

Previous studies have demonstrated the correlations between cyberbullying victimization and disordered eating behaviors in adolescents, however, limited attention has been paid to the long-term effects and underlying mechanisms, and studies focused on young adults are scarce. This study explored the association between cyberbullying victimization and disordered eating behaviors and the underlying mechanisms in a sample of young adults using a longitudinal design. A total of 955 Chinese young adults completed the Cyber Victim Subscale of the Cyber Victim and Bullying Scale, the Self-surveillance Subscale of the Objectified Body Consciousness Scale, the Self-compassion Scale-Short Form, and the Dutch Eating Behaviors Questionnaire three times with a 3-months interval. The results indicated that cyberbullying victimization was positively correlated with emotional eating and external eating after six months, but not with restrained eating. Moreover, self-compassion and self-objectification mediated the associations between cyberbullying victimization and the three kinds of disordered eating behaviors, however, in different ways. In the associations of cyberbullying victimization with restrained eating and external eating, the independent mediating effect of self-objectification and the serial mediating effect were significant, while in the association between cyberbullying victimization and emotional eating, only the independent mediating effect of self-compassion was significant. The findings indicated that the relations between cyberbullying with different kinds of disordered eating behaviors might have different mediation mechanisms, which sheds light on the prevention and intervention for disordered eating behaviors associated with cyberbullying in the future.
