The effects of media, self-esteem, and BMI on youth's unhealthy weight control behaviors

Adolescent's self-reported weight and its association with media impact on decision to lose weight and body thinness perception

This study investigated the accuracy of self-reported weight among Kuwaiti adolescents and the associations of self-reported weight and calculated BMI with the impact of media use on adolescent’s decision to lose weight and body thinness perception. A total of 706 Kuwaiti adolescents (363 females) 15–18 year-olds were randomly selected from schools. Weight and height were self-reported by the adolescents and measured by the researchers. A specifically designed questionnaire reported the impact of media use on adolescent’s decision to lose weight and body thinness perception. There were significant (p < 0.001) relationships between measured and reported weight (r = 0.947), height (r = 0.777), and calculated BMI (r = 0.623). Intraclass correlation coefficients (95% CI) between self-reported and measured weight and height were 0.973 (0.968–0.977) and 0.867 (0.839–0.891), respectively. The mean differences between self-reported and measured weight (1.26 kg) and BMI (0.478 kg/m²) were relatively small. Females under-reported their weight and the calculated BMI from estimated weight and height was underestimated by adolescents with overweight/obesity. The impact of media use on the adolescent’s perception of being thin relative to the accuracy of the calculated BMI was significant (p = 0.043–0.001). The age-adjusted odds ratio of the calculated (underestimated) BMI in adolescents without overweight/obesity was 0.437 (95% CI = 0.257–0.741; p = 0.002). It was concluded that the validity of self-reported weight was high. Adolescents with overweight/obesity were more likely to underestimate their weight and calculated BMI. Educating adolescents about proper lifestyles and weight loss through media appears warranted.

Disordered eating in a population-based sample of young adults during the COVID-19 outbreak

OBJECTIVE

The present study aimed to describe the experience of, and factors associated with, disordered eating in a population-based sample of emerging adults during the COVID-19 outbreak.

METHOD

Participants in the EAT 2010-2018 (Eating and Activity over Time) study were invited to complete the C-EAT (COVID-19 EAT) survey in April-May 2020. There were 720 respondents to the survey (age: 24.7 ± 2.0 years). Psychological distress, stress, stress management, financial difficulties, and food insecurity during the COVID-19 pandemic were examined as cross-sectional correlates of disordered eating in 2020. Open-ended questions assessed the perceived impact of the pandemic on eating behaviors.

RESULTS

Low stress management was significantly associated with a higher count of extreme unhealthy weight control behaviors (UWCBs). Food insecurity, higher depressive symptoms, and financial difficulties were significantly associated with a higher count of less extreme UWCBs. Higher stress and depressive symptoms were significantly associated with greater odds of binge eating. Six themes pertaining to disordered eating during the pandemic emerged: (a) mindless eating and snacking; (b) increased food consumption; (c) generalized decrease in appetite or dietary intake; (d) eating to cope; (e) pandemic-related reductions in dietary intake; and (f) re-emergence or marked increase in eating disorder symptoms.

DISCUSSION

Psychological distress, stress management, financial difficulties, and abrupt schedule changes may have contributed to disordered eating during the COVID-19 pandemic. Interventions that target stress management, depressive symptoms, and financial strain and provide tools to develop a routine may be particularly effective for emerging adults at risk of developing disordered eating during public health crises.

Associations between weight talk exposure and unhealthy weight control behaviors among young adults: A person-centered approach to examining how much the source and type of weight talk matters

This study characterized common patterns of weight talk and examined associations with unhealthy weight control behaviors (UWCBs) in young adults. Participants (n = 1298) were from EAT 2018 (Eating and Activity Over Time), a population-based study of emerging adults (mean age = 22.2; 53.6 % women). Latent class analyses (LCA) derived classes based on weight talk exposure for men and women. Generalized linear models examined the association between weight talk classes and extreme/less extreme UWCBs. LCA results revealed 4 patterns of weight talk exposure among young adult women: minimal weight talk (38.8 %), peer weight talk (35.2 %), multi-source weight talk (13.5 %), and parental weight talk (12.6 %). Three classes emerged among men: minimal weight talk (44.0 %), peer weight talk (29.7 %), and multi-source weight talk (26.3 %). Among young adult women, the parental weight talk class reported the highest levels of extreme and less extreme UWCBs. Among young adult men, the multi-source weight talk class reported the highest levels of less extreme UWCBs. Results provide evidence regarding the importance of parental weight talk, even among young adult children, whether or not parental weight talk is accompanied by peer weight talk. Parents have the potential to improve their young adults' weight-related behaviors through avoiding weight talk.

A test of the tripartite influence model of disordered eating among men

Studies of the Tripartite Influence Model conducted with female samples suggest that thinness-oriented pressures, internalization, and appearance comparisons may be risk factors for disordered eating. However, limited work has investigated this model among men utilizing measures specifically designed to assess both muscularity- and thinness-oriented processes, which characterize male body image concerns. To address this gap, the current study examined the Tripartite Influence Model of disordered eating among men using a battery of such measures. A convenience sample of 265 male undergraduates completed validated, self-report measures of disordered eating, muscularity- and thinness-oriented appearance pressures, internalization, and appearance comparisons. Path analyses supported a slightly modified version of the Tripartite Influence Model, indicating direct and indirect paths from sociocultural pressures to disordered eating via internalization and appearance comparisons. These results provide support for a version of the Tripartite Influence Model among men. Specifically, muscularity- and thinness-oriented pressures appear to be related to disordered eating among college men via indirect pathways involving thin internalization, muscular internalization, and appearance comparisons. Future work is needed, however, to examine whether the model would generalize to muscularity-oriented disordered eating.

The impact of body diversity vs thin-idealistic media messaging on health outcomes: an experimental study

The recent rise in body dissatisfaction and weight bias has led to a call to the media to increase the diversity of their imagery, in efforts to challenge the thin-ideal. Therefore, this study aimed to evaluate the effects of both body diversity and thin-ideal interventions on health outcomes. Female participants (n = 160) were randomly allocated into an intervention group: body diversity; thin-ideal; control. They completed measures of body satisfaction, body compassion, internalisation of the thin-ideal, weight bias and behavioural intentions at baseline and post-intervention. The results showed significant differences between groups for weight bias and intentions to eat healthily. Specifically, those in the body diversity intervention group reported a greater reduction in weight bias compared to the other conditions. Further, those in the thin-ideal intervention group reported a greater increase in intentions to eat healthily compared to the other conditions. There were no differences between groups for body satisfaction, body compassion, internalisation of the thin-ideal and behavioural intentions to exercise and manage weight. In conclusion, exposure to body diversity images reduced weight bias whereas exposure to the thin-ideal promoted intentions towards healthy eating. These findings therefore offer empirical evidence for the impact of using different types of imagery to change different health outcomes.

Psychological characteristics and eating attitudes in adolescents with drunkorexia behavior: an exploratory study

PURPOSE

Drunkorexia represents an emerging phenomenon that is still understudied especially among adolescents. The present study aimed to investigate the relation between drunkorexia and psychological characteristics relevant and commonly associated with existing forms of eating disorders.

METHODS

The sample was composed of 849 adolescents (513 boys, 334 girls, 2 unknown; range 14-22) who completed a survey composed of Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale and Psychological scales of the Eating Disorders Inventory-3.

RESULTS

Our findings highlighted that drunkorexia was associated with low self-esteem, personal alienation, interoceptive deficits, emotional dysregulation, and asceticism. Hierarchical multiple regression analysis indicated that difficulties with emotion regulation and ascetic tendencies were significant predictors of drunkorexia among adolescents.

CONCLUSIONS

Our findings suggest the importance for programs preventing drunkorexia to be focused on training adolescents in using more adaptive strategies to manage emotions and accepting both emotional and physical signals without feeling guilty or threatened.

Trends for weight control strategies in Korean adults using the Korea National Health and Nutrition Examination Survey from 2007 to 2017

BACKGROUND

Obesity is an increasing global health problem and is associated with various diseases including stroke, respiratory diseases, diabetes mellitus, and hypertension. Various weight control strategies such as exercise, calorie-restricted diet, anti-obesity medication, herbal medicine, and functional food are being used. The present study aimed to investigate the trends of weight control strategies in Korean adults METHODS: This was a cross-sectional study that used data from the Korea National Health and Nutrition Examination Survey from 2007 to 2017. A total of 64,207 participants were analyzed. The body mass index (BMI), subjective judgment of body appearance, practice of weight control, and methods to control weight were analyzed according to year and sex.

RESULTS

The prevalence rate of obesity in men based on a BMI of 25 or higher was slightly increased from 37.0% in 2007 to 41.1% in 2017. Among the weight control strategies, use of exercise decreased from 83.8% to 80.5% in men, and from 73.4% to 69.5% in women, reduction in the amount of food consumed increased from 47.1% to 60.5% in men and from 65.1% to 70.6% in women, consumption of functional food increased from 3% to 6.2% in men and from 3.2% to 8.7% in women, and rate of skipping meals increased from 6.1% to 12.0% in men and from 11.5% to 14.0% in women.

CONCLUSION

The present study showed that exercise has decreased and dietary control and functional food consumption have increased as weight control strategies in Korean adults during the past decade.

Gender Differences in Risk Factors Influencing Unhealthy Weight Control Behaviors among Adolescents

This study was conducted to identify risk factors that influence the probability and severity of unhealthy weight control behaviors (UWCBs) and to consider gender difference. Data were obtained from a national survey. The study population was composed of 66,068 adolescents in grades 7-12 at 400 middle schools. The effect of the independent variables on UWCBs was analyzed using zero inflated negative binominal regression. Higher body mass index group, overweight perception, appearance stress, and depressive mood were found to be risk factors of UWCBs' probability in both genders. For boys, older age, underweight, accurate or under-perception of weight, and depressive mood influenced severity of UWCBs. For girls, older age, appearance stress, and depressive mood influenced severity of UWCBs. The new findings mean to consider the range of UWCBs experienced, which can offer more sensitive and predictable information. Further interventions should be developed to consider gender specific risk factors.

Disordered eating behaviors among Christian and Muslim adolescents in Ceuta, a multicultural town

Studies on disordered eating behaviors (DEB) in multicultural populations with multiple religious/cultural affiliations are needed in order to clarify the relationship between cultural background and DEB. Therefore, we compared the presence of DEB among Christian and Muslim adolescents who share their school environment, controlling for the effect of body mass index, demographic variables and lifestyle habits. A sample of 493 girls and boys (339 Christian, 138 Muslim) whose mean (±SD) age was 14.8 (±1.7) years completed self-reporting questionnaires and underwent measurements of anthropometric data. Religious/cultural affiliation was defined by self-identification. The dependent variable, DEB was assessed by means of the Eating Disorders Inventory (EDI-2). Muslim girls and boys score higher than Christians on EDI-2 total scores, especially on the perfectionism subscale. Bivariate and multivariate analyses were used to determine the characteristics associated with DEB, which were detected in 24% of participants (19% of Christians and in 35% of Muslims). Among girls, DEB were directly associated with overweight or obesity, the presence of frequent quarrels with parents, academic failure and spending more than 3 h a day watching screen images. Among boys, DEB were directly associated with overweight or obesity and Muslim background; and inversely associated with age and socioeconomic status.
