RESUMO
Although social support has been linked to body satisfaction, there has been little research on the effect of differential sources of support on the trajectory of appearance esteem over time. To address this gap, this study explored changes in adolescents' appearance esteem to perceived social support over one year. Data were collected from 339 Canadian adolescents (54.57% females) in Grade 7 (Mage = 12.05) and Grade 10 (Mage = 15.14). Multilevel growth modeling revealed that perceived social support from fathers was not associated with appearance esteem, whereas mothers' support had the strongest effect on appearance esteem, consistently over time. Friends' support was also related to an increase in the appearance esteem trajectory, but only for older students. Overall, this prospective study provides a better understanding of the unique contribution of three different sources of social support during adolescence for preventing negative appearance esteem, beyond the effects of other related variables.

Considering the long-term deleterious consequences of child maltreatment, it is crucial to better understand the pathways leading to psychological outcomes in emerging adulthood. This study contributes to the existing knowledge through the examination of the role of romantic attachment as a mechanism explaining the association between child maltreatment and psychological adaptation. Prospective and retrospective data from 605 school-based participants (56.0% women) from the general population involved in a 10-year study were used. Child maltreatment, including sexual, physical, and emotional abuse, was measured at age 14 years (mean age = 14.04, SD = 0.21). Ten years later (mean age = 24.5, SD = 0.50), similar forms of maltreatment, in addition to neglect, were measured, along with adult romantic attachment, self-esteem, and psychological distress. The results of path analyses, controlling for self-esteem and psychological distress at age 14, revealed that child maltreatment was associated with increases in psychological distress and with decreases in self-esteem in emerging adults, through their levels of romantic attachment anxiety. The results also revealed that cross-sectional analyses involving retrospective measurements of child maltreatment at age 24 were as valuable as longitudinal analyses involving its measurement at age 14. Those results confirm the importance of romantic attachment in survivors' well-being, and suggest that attachment may be a key target for intervention with adolescents or emerging adults.

This longitudinal study aims to describe the development of body dissatisfaction (BD), measured with the Contour Drawing Rating Scale, between the ages of 14 and 18, and to identify factors associated with BD at age 18, among 413 adolescents. Between the ages of 14 and 18, the proportion of girls wanting to be thinner increased, although it remained unchanged among boys. A ratio of 1:2 girls and 1:5 boys reported having seriously tried to lose weight. Factors associated with BD in girls at age 18 were (1) wanting to be thinner, (2) body mass index (BMI), (3) weight control behaviours and (4) negative comments about weight. Factors associated with BD in boys at age 18 were (1) wanting to be thinner or bigger, (2) BMI, (3) having experienced sexual intercourse and (4) negative comments about weight. The high prevalence of BD and weight-related concerns suggest a need for early interventions.
RESUMO
INTRODUCTION: Restrained, emotional and intuitive eating were examined in relation to each other and as correlates of participants' weight status, body image and self-esteem. In some past research, restrained and emotional eating have been associated with higher weight status and poorer mental health, while intuitive eating is more frequently linked to lower weight status and more positive well-being. However, these eating styles have rarely been examined together and never in a large cross-country sample. METHOD: Six-thousand two-hundred and seventy-two (6272) emerging adults (M age = 21.54 years, SD = 3.13) completed scales from the Three-Factor Eating Questionnaire, the Eating Disorders Examination Questionnaire, the Intuitive Eating Scale-2, the Multidimensional Body Self Relations Questionnaire, the Rosenberg Self-Esteem Scale, and provided weight and height information that was used to calculate body mass index (BMI). Participants resided in Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States and provided information using an online survey. RESULTS: Path analyses for the entire sample revealed significant pathways between higher intuitive eating and higher body satisfaction and self-esteem, and lower BMIs among participants. Higher levels of restrained and emotional eating were associated with lower body satisfaction and self-esteem, and higher BMIs among participants. Minor cross-country differences were evident in these patterns of relations, but intuitive eating emerged as a consistent predictor across countries. CONCLUSION: Overall, findings suggest that efforts should be made to increase intuitive eating among emerging adults and to support individual and macrolevel interventions to decrease restrained and emotional eating behaviours.

The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research.

Background: Vitamin D-dependant rickets type 1A (VDDR1A) is a rare autosomal recessive disorder caused by pathogenic variants in the CYP27B1 gene. This gene is essential for vitamin D activation. Although VDDR1A is a rare condition worldwide, its prevalence is high in the Saguenay-Lac-Saint-Jean (SLSJ) region due to a founder effect. Daily intake of calcitriol before the onset of clinical manifestations can prevent them in affected children. Methods: A genetic screening test was developed and validated for the CYP27B1 gene c.262del pathogenic variant. Newborn screening was implemented in the SLSJ region for this variant, and the feasibility and acceptability were assessed. Sixteen medical records of children affected with VDDR1A were reviewed to document the consequences of the disease at diagnosis. Results: A total of 2000 newborns were tested for VDDR1A. Most families (96.5%) accepted the genetic test. We found a carrier rate of 1/29 for the c.262delG variant in our cohort, which is suggestive of a founder effect. We identified one child affected with VDDR1A and treatment was initiated before the onset of clinical manifestations. On average, children with VDDR1A were diagnosed at 13.8 ± 5 months of age, they had a significant failure to thrive at diagnosis, among other harmful health consequences. Conclusion: Our study showed that in our population, the newborn genetic screening program is safe and feasible, it has high acceptability, and it is efficient to identify affected children. VDDR1A health consequences can be prevented by early initiation of treatment. Therefore, screening programs should be available for populations where it is deemed as beneficial from a public health perspective.

Adolescents may be particularly vulnerable to the negative impact of the coronavirus disease 2019 (COVID-19) pandemic, given their increased socialization needs during this developmental period. This prospective study examined the potential changes in adolescents' well-being from before to during the pandemic, and the moderating role of a history of child maltreatment (CM), COVID-19-related distress, and gender among 1,802 adolescents (55.5% participants identified as boy, 42.2% as girl, and 1.5% as nonbinary; Mage 14.74 years). Another aim was to determine whether COVID-19-related distress mediated the relationship between CM and well-being. Results revealed that COVID-19-related distress was associated with lower well-being (i.e., higher levels of internalized and externalized behaviors, and lower levels of self-esteem and life satisfaction). Boys experienced a greater decrease in life satisfaction and self-esteem than girls. A history of CM had a moderation effect, with the pandemic having a lesser impact on the outcomes of adolescents with such a history. However, it was also associated with more COVID-19-related distress, which in turn was associated with lower levels of internalized and externalized behaviors, self-esteem, and life satisfaction. These unexpected results with regard to CM might indicate that the social restrictions during the pandemic could have had a relieving effect on adolescents with particular challenges associated with CM.

Although a range of risk factors have been identified for disordered eating and weight status, the breadth of risk factors have been rarely considered within a single, comprehensive model. The robustness of these findings across countries also remains an open question. The present study sampled 6272 participants aged 18-30 years from eight countries in an attempt to evaluate combined and unique predictors for these two conditions, and to explore possible cross-country differences in these models. Participants completed a range of demographic, biological, behavioral, psychological, and sociocultural measures to test a comprehensive model of the contributions of these predictors for disordered eating and weight-related constructs (binge eating, body mass index, compensatory behaviors, dietary restraint, drive for muscularity, and drive for leanness). Structural invariance testing within a multigroup path analysis framework revealed that a single model across the eight countries provided poor model fit. Freeing of 22% of parameters across countries provided excellent fit and a satisfactory compromise for country-invariant and country-variant parameters in the model. Overall, predictors accounted for between 15% and 60% of variance in the outcome measures, with lowest explained variance for the disordered eating outcomes. Significant unique contributions to prediction were observed for each of the five risk factor variable types and across the eight countries. Thus, the findings show strong support for this model as an explanatory framework of both disordered eating and weight status.

This study examined the measurement invariance of three scales that assessed emotional eating, restrained eating, and intuitive eating across eight countries (Australia, Belgium, Canada, China, Italy, Japan, Spain and the United States) in order to determine their suitability for cross-country body image research. A total of 6272 young adults took part in this study. Participants completed an online survey including the Emotional Eating subscale of the Three Factor Eating Questionnaire-Revised 21, the Restraint subscale of the Eating Disorder Examination Questionnaire, and the Reliance on Hunger and Satiety Cues subscale of The Intuitive Eating Scale-2. Multi-group confirmatory factor analysis was used to evaluate potential cross-country differences in functioning of the measures. Partial invariance for all three scales was found, with only minor levels of non-invariance identified. Multiple indicator multiple cause models identified BMI and gender as potential influences on scores for these measures. Sources of invariance across groups are discussed, as well as implications for further substantive research across countries involving these measures.

This study assessed the measurement invariance of selected self-report measures of perfectionism, impulsivity, self-esteem and social anxiety in samples of emerging adults from eight different countries. Participants (N = 6272) completed the Multidimensional Perfectionism Scale (MPS), the UPPS-P Impulsive Behavior Scale, the 5-item Rosenberg Self-Esteem Scale (5-item RSES) and the Social Interaction Anxiety Scale (SIAS-6). Multigroup confirmatory factor analysis was run to examine cross-measure equivalence. Evidence for structural invariance was found for all questionnaires, while weak invariance was supported only for the 5-item RSES and the SIAS-6, and a partial weak invariance was found for the MPS and the UPPS-P. No measure achieved strong invariance. Strict invariance was achieved for the 5-item RSES, whereas only a partial strict invariance was supported for the MPS, UPPS-P and SIAS-6. These results suggest that perfectionism, impulsivity, self-esteem, and social anxiety are subjected to linguistic/cultural influence as well as to the effects of socio-demographic variables and can be evaluated by using the selected measures in eight different countries worldwide - but results should be interpreted with caution.

Positive body image refers to individuals' ability to conceptualize their bodies with love, respect, and appreciation. The study of positive body image is relatively new, and instruments used to investigate this multi-faceted construct have received limited use in non-English speaking countries. Thus, the aim of this investigation is to consider four measures that are associated with positive body image across eight different countries. Participants (n = 6272) completed the Body Appreciation Scale-2, the Body Areas Satisfaction Scale, the Physical Appearance Comparison Scale, and the Weight Bias Internalization Scale. Multi-group confirmatory factor analyses (MG-CFAs) and item-response theory (IRT) models were used to examine the measurement invariance of these surveys. Our results generally suggest that positive body image, weight bias, and appearance comparison can be assessed using brief assessments and that these four instruments can be used in different countries, but care should be taken to consider individuals' gender, BMI, and socio-economic position.

The aim of this study was to examine the cross-country invariance of five well-established measures of body weight and shape concern-related attitudes and behaviors (i.e., drive for leanness, drive for muscularity, strategies to increase muscle, strategies to lose weight, and weight and shape concerns). A secondary objective was to examine the effects of several sociodemographic factors (age, BMI, socioeconomic status, and gender) on item and latent factor scores of these constructs. A total of 6272 emerging adults (4218 women; Mage = 21.46, SD = 3.11) from Australia, Belgium, Canada, China, Italy, Japan, Spain, and the U.S. completed a self-report online survey as part of a larger study. Overall, support for partial invariance both across countries and in terms of the considered sociodemographic factors was found for reduced versions of the five measures. Significant differences in latent means were found across countries, these being of greater magnitude for drive for leanness and strategies to lose weight. The considered sociodemographic factors (most notably BMI and gender) were associated with the latent mean scores of the assessed constructs. The present study contributes to current literature by providing cross-cultural invariant versions of several measures of relevance in the field of body image.

Aim: Although health authorities have set pharmacogenetic (PGx) markers on labels of hundreds of drugs, the use of PGx in clinical care remains infrequent. The adoption of PGx will depend on the opinions of physicians, pharmacists and patients. Materials & methods: Qualitative focus group interviews were performed with 23 physicians, 11 pharmacists and 30 patients. Results: Majority of the participants showed enthusiasm toward the implementation of PGx in clinics. Lack of knowledge on PGx, roles of healthcare providers, factors in favor and challenges of PGx implementation, ethical and insurance issues, educational and tools needs were the key themes that emerged from the interviews. Conclusion: Several barriers impede the uptake of PGx in clinics, however, opinions of physicians, pharmacists and patients are mostly favorable.

Research has demonstrated that eating disorders (ED) and higher weight have lifetime co-occurrence suggesting that they may be best considered within a common etiological model. Although we know that body dissatisfaction is likely to be a risk factor for both outcomes, other proposed risk and protective factors for each condition have not been adequately explored. The current paper tests a conceptual model that is based on a review of the existing literature from both areas of scholarship. It considers biological, sociocultural, psychological, and behavioral factors that may contribute to both outcomes. The model will be tested in a longitudinal design with an initial sample of 600 emerging adults (aged 18-30) per country in nine different countries (total sampleâ¯=â¯5400 participants). Questionnaires will be completed online on two occasions, 12 months apart. The first full phase of the study commenced in July 2018, the same time Body Image was approached to publish this protocol paper (the final revised paper was submitted in September 2019), and data collection will be finalized in December 2019. Multi-group path analysis will identify the biopsychosocial predictors - both cross-sectionally and longitudinally - of both ED and higher weight, and how these vary across countries and gender.

BACKGROUND: Transition into adulthood is a critical developmental period that may be influenced by adverse life events as well as by protective factors. This study aimed at investigating the effect of different forms of child maltreatment experienced prior to age 14 (i.e., sexual abuse, physical abuse and exposure to intimate partner violence), and of friend support at age 14 on the psychological distress trajectory from age 14 to 24. METHODS: Participants were 605 adolescents from the general population involved in a 10-year longitudinal study. Psychological distress was evaluated at ages 14, 16, 18 and 24. Child maltreatment prior to 14 years was retrospectively assessed at 14 and 24 years while perception of support from friends was evaluated at age 14. RESULTS: Multilevel growth modeling indicated that psychological distress followed a significant decreasing curvilinear trajectory, with participants reporting fewer distressing psychological symptoms after 18 years. All three forms of child maltreatment, as well as their cumulative effect, predicted more psychological distress over 10 years above and beyond the protective effect of support from friends. Higher support from friends at age 14 was related to lower distress at baseline andover 10 years, beyond the effect of child maltreatment. LIMITATIONS: Self-report nature of all measures, attrition, and measures of child maltreatment forms. CONCLUSIONS: Psychological distress decreased during the transition from adolescence to emerging adulthood. Results also revealed the detrimental impact of child maltreatment and the promotive role of friend support, which underscore the importance of early intervention.
