Body Image Dissatisfaction and the Adrenarchal Transition

Body image dissatisfaction during the first year of pediatric inflammatory bowel disease diagnosis

OBJECTIVES

Dissatisfaction with one's body can be distressing; youth with inflammatory bowel disease (IBD) may be at increased risk for body image dissatisfaction given disease symptoms and treatment side effects. Yet, no studies have examined body image dissatisfaction over time in youth with IBD and whether depressive symptoms are associated with change in dissatisfaction.

METHODS

Fifty-seven pediatric participants (8-17 years old) newly diagnosed with IBD were enrolled. Youth completed questionnaires assessing body image dissatisfaction and depressive symptoms shortly after diagnosis (Time 1) and 12 months later (Time 2). Multilevel longitudinal modeling was used to test the extent to which body image dissatisfaction changed across the first year of diagnosis and to test change in body image dissatisfaction as a function of depressive symptoms.

RESULTS

Findings indicated significant between- and within-person variance in body image dissatisfaction over the 12 months, yet the sample as a whole did not report significant changes in dissatisfaction from Time 1 to Time 2. Children reporting depressive symptoms greater than their individual average over time reported greater body image dissatisfaction. Between-person variation in depressive symptoms demonstrated a significant interaction with time. As an individual's depressive symptoms exceeded the group average, their body image dissatisfaction increased, although less drastically as time since diagnosis progressed.

CONCLUSIONS

Findings suggest that body image dissatisfaction is a complex and dynamic construct across youth and that interventions for pediatric IBD patients need to be tailored to the needs of individuals. Methods for assessing body image dissatisfaction efficiently and repeatedly across multiple visits are provided.

Male eating disorders in midlife-possible links between excessive sports and hormones

Although eating disorders were long considered a typical female disorder, it is now clear that men are also affected. However, the literature on eating disorders in men is still very limited, and the actual extent is not known. Even less is known about the epidemiology of eating disorders in older individuals. In this focused review, we will present an update of the available data on disordered eating and eating disorders in middle-aged and older males. In addition, we will highlight the relationship of eating disorders with excessive sports as a purging method of choice for this age group and discuss the impact of age-related hormonal imbalances in aging men.

Pubertal progression and its relationship to psychological and behavioral outcomes among adolescent boys

Variations in pubertal timing and tempo have relevance to psychosocial development. Accounting for pubertal timing, tempo, and psychosocial development simultaneously in a model remains challenging. This study aimed to document the typology of pubertal development in a cohort of Taiwanese adolescent boys and then to examine how the associations between psychosocial variables across time vary by the patterns of pubertal development. A group of adolescent boys (n = 1,368) reported pubertal signs and psychosocial variables for 3 years since seventh grade. The growth mixture model revealed three major classes of pubertal transition: average pubertal growth, late-onset with rapid catch-up, and late-onset with slow catch-up. In a cross-lagged panel model, the multigroup analysis found the regression coefficients mostly invariant across all three classes, except those between deviant behavior and subsequent changes in depressive symptoms that were significantly positive only in the late-onset with slow catch-up group. Adolescent boys in this group were estimated to have the highest marginal level of depressive symptoms and deviant behavior in ninth grade among the three classes. Our study highlights the heterogeneity in boys' pubertal development and the role of the pubertal development pattern in their psychosocial development.

Breasts, Butts, and Thighs—Oh My! Weight Spurt and Body Image Messages in Girls’ Puberty Books

Analyze popular girls’ puberty books to understand what messages they portray about weight spurt and body image. A critical ethnography was conducted of 13 best-selling books about girls’ puberty. This analysis specifically focused on messages about weight gain/spurt and body image presented in the books and whether these were aligned with larger cultural understandings of weight gain and body image. A data-driven thematic analysis was conducted on the portions of each book relevant to weight gain and body image. The cultural fat-phobic scripts were prevalent in the books, contrasting the well-intended developmental messages. Discussions of weight tended to be negatively framed and weight gain expectations were distressingly vague. The books discussed the necessity of and biological rationale for those changes while normalizing variation in timing. The books also focused on developing a positive body image during this time. Understanding this allows us to see the pervasive, conflicting messages about weight-spurts that girls are receiving from these resources, which can be used to tailor book choice and outreach programs.

Growth and adrenarche: findings from the CATS observational study

BACKGROUND

There is increasing evidence that patterns of pubertal maturation are associated with different patterns of health risk. This study aimed to explore the associations between anthropometric measures and salivary androgen concentrations in pre-adolescent children.

METHODS

We analysed a stratified random sample (N=1151) of pupils aged 8-9 years old from 43 primary schools in Melbourne, Australia from the Childhood to Adolescence Transition Study. Saliva samples were assayed for dehydroepiandrosterone (DHEA), DHEA-sulfate and testosterone. Anthropometric measures included height, weight, body mass index (BMI) and waist circumference. Associations between (1) anthropometric measures and each androgen, and (2) hormone status with obesity and parental report of pubertal development were investigated using linear regression modelling with general estimating equations.

RESULTS

Greater height, weight, BMI and waist circumference were positively associated with higher androgen concentrations, after adjusting for sex and socioeconomic status. Being overweight or obese was associated with higher testosterone and DHEA concentrations compared with the normal BMI category. Those who were obese were more likely (OR=2.7, 95% CI 1.61 to 4.43, p<0.001) to be in the top tertile of age-adjusted androgen status in both sexes.

CONCLUSION

This study provides clear evidence for an association between obesity and higher androgen levels in mid-childhood. The adrenal transition may be a critical time period for weight management intervention strategies in order to manage the risk for metabolic problems in later life for high-risk individuals.

Body Size Misperception and Dissatisfaction in Elementary School Children

Background: To examine the association between body size perception (BSP) and body size dissatisfaction (BSD) in elementary school children and to document the potential contribution of individual factors [age, sex, and actual body size (BMI Z-scores: BMIZ)] that may influence their relationship. Methods: This study included 269 children (124 boys and 145 girls) between 6 and 13 years of age (9.2 ± 1.6 years). The BSP score was calculated as the difference between the perceived actual body size and BMIZ (actual body size). A negative BSP score indicated an underestimation of their body size. To assess the BSD score, the difference between perceived actual body size and desired body size was calculated. A positive BSD score indicated a desire to be thinner. Results: Perceived actual body size was smaller than BMIZ, independent of age group and weight status. Overall, 64% of children underestimated their body size. The young children living with obesity demonstrated the highest misperception. Results also showed that the proportion of children who desired to be thinner was higher in overweight and obese subgroups. No significant relationship was found between BSP and BSD scores in the entire sample, while a positive association was observed among younger children in the normal-weight and obese subgroups (r = 0.40; p < 0.001 and r = 0.78; p < 0.05, respectively). Conclusions: Underestimation and dissatisfaction of body size are more prevalent in children living with overweight/obesity. Moreover, there is an association between BSP and dissatisfaction, yet this association is dependent on age and weight status.

Princess Power: Longitudinal Associations Between Engagement With Princess Culture in Preschool and Gender Stereotypical Behavior, Body Esteem, and Hegemonic Masculinity in Early Adolescence

Princess culture is criticized for contributing to gender stereotypes and poor body esteem, however, there is little longitudinal research examining these claims. This study examines associations between engagement with princess culture during early childhood and gender stereotypes, body esteem, and adherence to hegemonic masculinity in early adolescence. Participants included 307 children (51% female, M_age  = 4.83 years, 87% White) who completed questionnaires at two time points, 5 years apart. The results indicated that early engagement with princess culture was not associated with later adherence to female gender stereotypes. However, princess engagement was associated with lower adherence to norms of hegemonic masculinity and higher body esteem. Socioeconomic status and gender moderated the results. Effect sizes were small to moderate. The changing nature of Disney princesses is discussed in the context of gender development across childhood.

A Narrative Review of Sex Differences in Eating Disorders: Is There a Biological Basis?

PURPOSE

Eating disorders and their core symptoms (eg, binge eating, body weight/shape concerns) disproportionately affect females, and these sex-differentiated effects become prominent during and after puberty. Although psychosocial influences such as heightened sociocultural pressures for thinness in girls and women contribute to this sex imbalance, biological factors could also play an important role.

METHODS

This narrative review summarizes evidence of biological factors underlying the sex-differentiated prevalence of eating pathology as well as within-sex variability in risk.

FINDINGS

There are sex differences in the pubertal emergence of genetic effects on eating pathology (adrenarche in males; gonadarche in females), and at least some genetic contributions to eating pathology seem to vary between the sexes. Furthermore, sex steroid hormones (eg, testosterone, estradiol, progesterone) are leading contributors to differential risk for eating pathology in males and females across the life span. Emerging data suggest that between-sex and within-sex variability in risk might occur via hormone-driven modulation (activation/deactivation) of genetic influences and neural responsiveness to food-related cues.

IMPLICATIONS

There is a biological basis to heightened risk for eating pathology in females, relative to males, as well as unique biological influences within each sex. Findings from this review highlight the importance of studying both sexes and considering sex-specific biological mechanisms that may underlie differential risk for eating pathology.
