Prevalence of screening-detected eating disorders in chinese females and exploratory associations with dietary practices

Eating disorders and health literacy in Germany: results from two representative samples of adolescents and adults

Introduction

Eating disorders are associated with substantial burden for the affected individuals including negative health outcomes and increased mortality. So far, prevention programs for eating disorders have yielded mixed results concerning their efficacy. Therefore, more targeted prevention programs need to be developed. Health literacy has been identified as a potential influencing factor of eating disorders. This study aimed at exploring the relationship between likely cases of eating disorders and health literacy, alongside additional sociodemographic factors.

Materials and methods

Two large samples of adults (N = 3,011) and adolescents (N = 1,021) representative of the German-speaking population in Germany were recruited. Likely cases of eating disorders were identified using the SCOFF questionnaire. Health literacy was assessed with the HLS-EU-Q16 questionnaire. Sociodemographic information, including age, gender, social status and level of education, and subjective body image were obtained. χ2-tests of independence were calculated to determine the association between the investigated constructs.

Results

Suspected eating disorders were more likely in female than male adolescents but were not related to gender in adults. Rates of suspected eating disorders increased with increasing age in adolescents and decreased with increasing age in adults. While levels of education were unrelated to suspected eating disorders, low social status was associated with higher rates of suspected eating disorders in adults but not adolescents. Inadequate or problematic health literacy and negative body image were associated with higher rates of suspected eating disorders compared to adequate health literacy and more positive body image.

Discussion

Likely cases of eating disorders are related to health literacy and body image as well as sociodemographic factors. These constructs should therefore be addressed in future research to improve prevention programs.

The use and misuse of the SCOFF screening measure over two decades: a systematic literature review

PURPOSE

The SCOFF questionnaire was designed as a simple, memorable screening tool to raise suspicion that a person might have an eating disorder. It is over 20 years since the creation of the SCOFF, during which time it has been widely used. Considering this, we wish to review the use of the SCOFF in peer-reviewed scientific journals, and to assess whether it is being used appropriately in the manner in which it was originally devised and tested.

METHODS

The Preferred Reporting Items for a Systematic Review and Meta-analysis (PRISMA) guidelines were followed, and all search strategies and methods were determined before the onset of the study. PubMed and Wiley Online Library were searched using the terms SCOFF and eating. Two reviewers were involved in the reviewing process. Criteria for appropriate use of the SCOFF were formalised with the tool's original authors.

RESULTS

180 articles were included in the final review. 48 articles had used the SCOFF appropriately, 117 articles inappropriately and 15 articles had been mixed in the appropriateness of their use.

CONCLUSION

This systematic review highlights the inappropriate use of the SCOFF in diverse languages and settings. When used correctly the SCOFF has made a significant contribution to the understanding of eating disorders and its simplicity has been applauded and led to widespread use. However in over two-thirds of studies, the use of the SCOFF was inappropriate and the paper highlights how and in what way it was misused, Guidelines for the appropriate use of the SCOFF are stated. Future validation and avenues of research are suggested.

Exploring the prospective relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents

OBJECTIVE

Relationships exist between food addiction symptoms, weight bias internalization, and psychological distress, yet previous research is primarily cross-sectional with adults from Western contexts. We examined the prospective relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents.

METHODS

Over three time points (Time 1, baseline; Time 2, 6-months; Time 3, 12-months) spanning 1 year, we examined cross-sectional and bi-directional relationships between food addiction symptoms, weight bias internalization, and psychological distress in Chinese adolescents (N = 589; aged 14-18 years at baseline). Pearson correlations and cross-lagged models examined the cross-sectional and longitudinal relationships between food addiction symptoms, weight bias internalization, and psychological distress.

RESULTS

Cross-sectional correlations suggested positive relationships between food addiction symptoms, weight bias internalization, and psychological distress at each time point. Regarding bi-directional relationships, higher psychological distress was associated with both higher weight bias internalization and higher food addiction symptoms at the following time points. However, food addiction symptoms and weight bias internalization were not prospectively associated. Time 2 psychological distress did not significantly mediate the relationship between Time 1 weight bias internalization and Time 3 food addiction symptoms.

DISCUSSION

Findings suggest no direct longitudinal link between food addiction symptoms and weight bias internalization and vice versa. However, findings do suggest that psychological distress is temporally associated with higher food addiction symptoms and weight bias internalization in Chinese adolescents. Targeting psychological distress may prove useful in treatments of food addiction symptoms and weight bias internalization in Chinese adolescents.

PUBLIC SIGNIFICANCE

Positive associations exist between food addiction symptoms, weight bias internalization, and psychological distress, but findings are largely cross-sectional and bound to adult populations from Western contexts. Using a longitudinal design in Chinese adolescents, findings suggested that baseline psychological distress was associated with higher food addiction symptoms and higher weight bias internalization at follow-up time points. Treatments targeting psychological distress may be helpful in reducing food addiction symptoms and weight bias internalization in Chinese adolescents.

Examining an integrated sociocultural and objectification model of thinness- and muscularity-oriented disordered eating in Chinese older men and women

OBJECTIVE

We tested an integrated model of three prominent theories of disordered eating (tripartite influence theory, objectification theory, and social comparison theory) in a sample of older Chinese men and women.

METHOD

Chinese older men (n = 270) and women (n = 160) completed questionnaires assessing the tripartite influence, objectification, and social comparison theories and thinness- and muscularity-oriented disordered eating. Two structural equation models were tested in Chinese older men and women.

RESULTS

The integrated model showed good model fit and described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older men and women. Higher appearance pressures were uniquely related to higher muscularity-oriented disordered eating in men. Across both gender groups, higher thinness internalization was uniquely related to higher thinness- and muscularity-oriented disordered eating, and in women only, higher muscularity internalization was uniquely related to lower thinness-oriented disordered eating. In men, higher upward and downward body image comparisons were uniquely related to higher and lower, respectively, muscularity-oriented disordered eating. In women, higher upward body image comparisons were only uniquely related to higher muscularity-oriented disordered eating while higher downward body image comparisons were uniquely related to both outcomes. Higher body shame was uniquely related to higher thinness-oriented disordered eating across both groups and in men alone, higher body shame was also uniquely related to higher muscularity-oriented disordered eating.

DISCUSSION

Findings, which tested the integration of tripartite influence, objectification, and social comparison theories, inform the prevention and treatment of disordered eating in Chinese older populations.

PUBLIC SIGNIFICANCE

The present study is the first to describe theories of disordered eating (tripartite influence, objectification, and social comparison) in Chinese older adults. Findings suggested good model fit and the integrated models described meaningful variance in thinness- and muscularity-oriented disordered eating in Chinese older women and men. Findings extend existing theories of disordered eating and, pending further study, may inform theory-driven prevention and treatment approaches in Chinese older adults.

The Chinese version of the Functionality Appreciation Scale: Psychometric properties and measurement invariance across gender and age

BACKGROUND

Functionality appreciation, as an important aspect of positive image, is associated with fewer body image disturbances, fewer disordered eating behaviors, and improved psychological well-being. However, it has been under-researched in Asian countries. The current work aimed to examine the psychometric properties of the Functionality Appreciation Scale (FAS) among four Chinese samples of different ages, and further examine measurement invariance and differences of the FAS across gender and age groups.

METHODS

Exploratory and confirmatory factor analyses (EFA and CFA) were conducted to examine the factorial structure of the FAS among four Chinese samples of different ages, including middle school adolescents (n = 894, M_age = 12.17 years), high school adolescents (n = 1347, M_age = 15.07 years), young adults (n = 473, M_age = 21.95 years), and older adults (n = 313, M_age = 67.90 years). The measurement invariance of the FAS across gender and age was examined. Internal consistency reliability and construct validity were evaluated.

RESULTS

The FAS had a unidimensional structure and was invariant across gender and age groups. The FAS presented sound psychometric properties in all age groups by gender, with good internal consistency reliability [e.g., high Cronbach's α values (.91 ~ .97)] and good construct validity (e.g., significant associations with body appreciation, body dissatisfaction, and disordered eating). Moreover, group comparisons showed minimal gender differences in functionality appreciation. However, significant age differences were found in functionality appreciation, with older ages generally associated with higher functionality appreciation.

CONCLUSION

Overall, findings suggest that the FAS is a sound instrument to be used in the Chinese context. Furthermore, functionality appreciation was found to be higher in older adults than adolescents or young adults, suggesting the potential important role of aging in functionality appreciation.

Global Proportion of Disordered Eating in Children and Adolescents: A Systematic Review and Meta-analysis

Importance

The 5-item Sick, Control, One, Fat, Food (SCOFF) questionnaire is the most widely used screening measure for eating disorders. However, no previous systematic review and meta-analysis determined the proportion of disordered eating among children and adolescents.

Objective

To establish the proportion among children and adolescents of disordered eating as assessed with the SCOFF tool.

Data Sources

Four databases were systematically searched (PubMed, Scopus, Web of Science, and the Cochrane Library) with date limits from January 1999 to November 2022.

Study Selection

Studies were required to meet the following criteria: (1) participants: studies of community samples of children and adolescents aged 6 to 18 years and (2) outcome: disordered eating assessed by the SCOFF questionnaire. The exclusion criteria included (1) studies conducted with young people who had a diagnosis of physical or mental disorders; (2) studies that were published before 1999 because the SCOFF questionnaire was designed in that year; (3) studies in which data were collected during COVID-19 because they could introduce selection bias; (4) studies based on data from the same surveys/studies to avoid duplication; and (5) systematic reviews and/or meta-analyses and qualitative and case studies.

Data Extraction and Synthesis

A systematic review and meta-analysis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline.

Main Outcomes and Measures

Proportion of disordered eating among children and adolescents assessed with the SCOFF tool.

Results

Thirty-two studies, including 63 181 participants, from 16 countries were included in this systematic review and meta-analysis. The overall proportion of children and adolescents with disordered eating was 22.36% (95% CI, 18.84%-26.09%; P < .001; n = 63 181) (I2 = 98.58%). Girls were significantly more likely to report disordered eating (30.03%; 95% CI, 25.61%-34.65%; n = 27 548) than boys (16.98%; 95% CI, 13.46%-20.81%; n = 26 170) (P < .001). Disordered eating became more elevated with increasing age (B, 0.03; 95% CI, 0-0.06; P = .049) and body mass index (B, 0.03; 95% CI, 0.01-0.05; P < .001).

Conclusions and Relevance

In this systematic review and meta-analysis, the available evidence from 32 studies comprising large samples from 16 countries showed that 22% of children and adolescents showed disordered eating according to the SCOFF tool. Proportion of disordered eating was further elevated among girls, as well as with increasing age and body mass index. These high figures are concerning from a public health perspective and highlight the need to implement strategies for preventing eating disorders.

Prevalence of Disordered Eating and Its Associated Factors From a Socioecological Approach Among a Sample of Spanish Adolescents: The EHDLA Study

Objectives: The aim of this study was twofold: a) to establish the prevalence of adolescents with disordered eating and b) to determine the factors associated with this prevalence in a sample of Spanish adolescents from the Valle de Ricote (Region of Murcia, Spain).

Methods: This cross-sectional study analyzed data from 730 adolescents (56.2% girls) from the EHDLA study. To determine the prevalence of disordered eating, the Sick, Control, One stone, Fat, Food (SCOFF) questionnaire was used. A socioecological approach was used to identify individual-, interpersonal-, or organizational-level factors associated with disordered eating.

Results: The prevalence of disordered eating was 30.1%. This condition was associated with female sex (odds ratio [OR] = 2.60; 95% confidence interval [CI], 1.81–3.73), immigrant status (OR = 2.22; 95% CI, 1.51–3.25), or excess weight (OR = 2.74; 95% CI, 1.93–3.89). Furthermore, for each additional hour slept, lower odds of having disordered eating were found (OR = 0.81; 95% CI, 0.67–0.98).

Discussion: Almost one-third of the sample of Spanish adolescents analyzed reported disordered eating. Female sex, immigrant status and excess weight are individual aspects that seem to be related to disordered eating among Spanish adolescents.

Relationships between weight bias internalization and biopsychosocial health outcomes: A prospective study in Chinese adolescents

OBJECTIVE

An extensive literature has documented the deleterious effects of weight bias internalization (WBI) on biopsychosocial health outcomes. Still, this research is largely confined to the Western context. Furthermore, few studies have explored associations between WBI and biopsychosocial health outcomes, including in non-Western adolescent populations.

METHOD

The present study explored the longitudinal relationships between WBI and body dissatisfaction, disordered eating, psychosocial impairment related to eating disorder features, and psychological and physical well-being in a sample (N = 1549; aged 11-18 years at baseline) of Chinese adolescents. Relationships between study variables were examined between two waves of data measurement (Time 1, baseline, and Time 2, 6-month). Cross-lagged and multivariate models were used to explore prospective relationships between WBI and biopsychosocial correlates.

RESULTS

Bidirectional relationships were observed between WBI and biopsychosocial correlates in Chinese adolescents. Adjusting for covariates and other predictor variables, higher body dissatisfaction, disordered eating, psychosocial impairment, and psychological distress at Time 1 predicted higher WBI at Time 2. Furthermore, higher WBI at Time 1 predicted higher body dissatisfaction, disordered eating, psychosocial impairment, and psychological distress at Time 2.

DISCUSSION

Weight bias internalization and psychosocial correlates were interrelated across time in Chinese adolescents. Improving WBI might be promising in the prevention of eating and body image disturbances and diminished psychosocial well-being. Similarly, reducing eating and body image disturbances and improving psychosocial well-being might be useful prevention targets in reducing WBI in Chinese adolescents.

PUBLIC SIGNIFICANCE

The present study represents an initial effort to explore bidirectional relationships between WBI and biopsychosocial health outcomes in Chinese adolescents. Findings suggest bidirectional relationships between WBI and psychosocial variables, highlighting the potential utility of incorporating WBI interventions into eating pathology and poor psychosocial well-being prevention designs for Chinese adolescents.

The Reliability and Validation of the Children's Eating Attitude Test among Chinese Samples

The purpose of this study was to examine the psychometric properties of the Children's Eating Attitude Test (ChEAT) in a Chinese sample. A total of 906 children (mean age = 10.55, SD = 1.08) from three primary schools were evaluated by the ChEAT. Factor analysis was performed to examine the factor structure of the ChEAT. The children's body mass index (BMI) was applied to assess the concurrent validity of the ChEAT. The ChEAT showed good internal consistency (Cronbach's α = 0.819) and split-half reliability (0.816) in Chinese children. Exploratory factor analysis suggested a four-factor structure, consistent with previous studies, which explained 41.16% of the total variance. Confirmatory factor analysis indicated good construct validity for the Chinese sample. The Chinese version of the ChEAT showed evidence for reliability and validity to evaluate the eating attitudes and behaviors for Chinese children. The mean score of each factor of the ChEAT differed significantly among different genders and BMI groups. Overweight girls had more eating disorder problems than normal-weight girls, and boys with lower BMI showed higher social eating pressure.

Integrating the tripartite influence, minority stress, and social comparison theories to explain body image and disordered eating in Chinese sexual minority men and women

Theories of eating pathology explain body image and disordered eating in diverse populations, including sexual minority (SM) individuals. Yet, previous efforts to extend theories of eating pathology to SM individuals have mostly focused on Western populations. The present study integrated the tripartite influence, minority stress, and social comparison models to explain variance in body image and disordered eating in Chinese SM men and women. Chinese self-identified SM adults (N = 1051; n = 519 men, n = 532 women) completed an online, cross-sectional study that assessed sociocultural influences (e.g., tripartite influence), minority stress, social comparisons, drive for muscularity, and disordered eating. Two integrated models were tested for men and women using structural equation modeling. Across both populations, sociocultural influences exerted the largest direct positive effects on body image and disordered eating. In men, only downward body image comparisons were uniquely related to outcomes. In women, higher upward body image comparisons were uniquely associated with higher drive for muscularity and higher downward body image comparisons were uniquely associated with higher thinness-oriented disordered eating. Minority stressors (e.g., sexual orientation concealment, internalized homophobia) were uniquely related to outcomes in men, not women. Findings extend existing theories of body image and disordered eating to Chinese SM populations.

ADHD Symptoms and Obesity in Chinese Children and Adolescents: A Longitudinal Study With Abnormal Eating Behaviors as Moderating Factors

BACKGROUND

Emerging studies have explored the possibility of ADHD and associated abnormal eating behaviors as catalysts for obesity in children and adolescents. However, results were largely inconsistent. This study aims to explore the effects of ADHD and abnormal eating behaviors (including eating disorders, emotional eating, and bedtime eating) on obesity, and to assess the moderating role of abnormal eating behaviors between ADHD symptoms and BMI in Chinese children and adolescents.

METHODS

We recruited 546 grade 3 to 11 students and their parents by stratified random sampling from three primary schools and four middle schools in Shanghai, China. This study used parent-reported versions of the ADHD Rating Scale-IV to assess ADHD symptoms, the Eating Attitudes Test and the Children's Eating Attitude Test to assess eating disorder (ED) symptoms, and the Child Eating Behavior Questionnaire to collect information about other abnormal eating behaviors at baseline and at a follow-up survey 1 year later.

RESULTS

Hierarchical linear regression analysis revealed that ED played a moderating role in the relationship between ADHD symptoms and BMI in addition to age (β = .003, p = .008). The simple slope test showed that ADHD symptoms positively correlated with BMI ofs in the older age group with a high level of ED symptoms (β = .16, p < .001). Moreover, the baseline ED symptoms (β = .03, p = .032) and ADHD symptoms (β = .12, p = .015) increased the students' BMI one year later after controlling for confounding factors.

CONCLUSION

Findings of this study suggest that ADHD and ED symptoms raised the students' BMI separately. Moreover, ADHD and ED symptoms raised the students' BMI separately. Moreover, a combined high level of ADHD and ED symptoms is correlated with students' high BMI in the older age group.

Screen-detected disordered eating and related traits in a large population sample of females in mainland China: China Health and Nutrition Survey

OBJECTIVE

We describe the prevalence and sociodemographic factors associated with screen-detected disordered eating and related traits in a population-based sample of women in China. We also explored prevalence trends over time.

METHOD

A total of 4,218 females aged 12-50 were sampled from 15 provinces as part of the China Health and Nutrition Survey (CHNS) in 2015. The SCOFF questionnaire screened for disordered eating and the selected questions from the Eating Disorders Examination-Questionnaire measured dietary restraint, shape concerns, and weight concerns. Body mass index (BMI) was measured and sociodemographic factors captured urban/rural residence, age, ethnicity, income, education, marital status, and occupational status. We calculated the prevalence of screen-detected disordered eating and related traits broadly and across several dimensions and compared prevalence estimates to 2009 and 2011 reports.

RESULTS

We detected 296 individuals who screened positive for disordered eating on the SCOFF (prevalence = 7.04%). Positive screens were associated with urban residence (p = .002) and higher education levels (p < .001). Scores on restraint, shape concerns, and weight concerns were all higher for individuals in urban versus village locations (all p's < .001), and with higher BMI (p < .001) for shape and weight concerns. The prevalence of screen-detected disordered eating increased numerically across 2009, 2011, and 2015.

DISCUSSION

The prevalence of screen-detected disordered eating in mainland China was comparable to other populations worldwide obtained from a recent meta-analysis. The distribution of disordered eating and related traits varied by several sociodemographic factors, which include age, BMI, urban/rural residence, education, and income, suggesting important directions for case detection and intervention in China.

Burden of Eating Disorders in China, 1990-2019: An Updated Systematic Analysis of the Global Burden of Disease Study 2019

Background: Eating disorders, including anorexia nervosa (AN) and bulimia nervosa (BN), are complex mental disorders. A better understanding of the burden of eating disorders is essential for improving their management. Information about the burden of eating disorders at the national level in China remains unclear. Methods: This is a systematic analysis of the Global Burden of Disease Study (GBD) 2019. The sex- and age-specific prevalence, incidence, and disability-adjusted life years (DALYs) of eating disorders in China were estimated by systematically reviewing all available epidemiological data and inputting these data into a Bayesian meta-regression tool (DisMod-MR 2.0). Trends in the age-standardized prevalence, incidence, and DALYs due to AN and BN were assessed from 1990 to 2019. Results: The age-standardized incidence rate (ASIR), prevalence rate (ASPR), and DALY rate per 100,000 population were estimated to be 13.22 (95% UI, 9.35-18.23), 38.08 (95% UI: 26.37-55.73), and 8.38 (95% UI, 4.87-13.35) for AN and 130.05 (95% UI, 84.02-187.13), 75.21 (95% UI, 48.52-105.97), and 16.16 (95% UI, 9.23-25.40) for BN, respectively, in 2019. The prevalence, incidence, and DALY rate of AN peaked at 15-19 years old. The prevalence and DALY rate of BN peaked at 30-34 years old. Females had a higher burden of AN and a lower burden of BN than males. The ASIR, ASPR, and DALY significantly increased by 1.3% (95% CI: 1.3-1.4%), 1.6% (95% CI, 1.5-1.6%), and 1.6% (95% CI, 1.5-1.7%) for AN and 1.4% (95% CI: 1.4-1.4%), 2.0% (95% CI, 2.0-2.1%), and 2.0% (95% CI, 2.0-2.1%) for BN, respectively, from 1990 to 2019 in China. In addition, the increments in all the age-standardized measures of BN were higher in males than in females. Conclusions: The burden of eating disorders in China showed unexpected patterns that varied by sex and age, with increasing trends of AN and BN from 1990 to 2019. More attention should be given to improving the burden of BN in males in China.

Course, risk factors, and adverse outcomes of disordered eating in pregnancy

OBJECTIVE

Although eating disorders in pregnancy have been studied extensively, little research attention has been given to disordered eating. The objectives of the present study were to determine the prevalence and levels of disordered eating in the perinatal period, and to identify risk factors and adverse outcomes of disordered eating during pregnancy.

METHOD

A prospective longitudinal design with a quantitative approach was adopted. A consecutive sample of 1,470 Chinese pregnant women from hospitals in Hong Kong was assessed using standardized instruments at five time points from the first trimester to 6 months postpartum.

RESULTS

The levels of disordered eating changed significantly across trimesters. Higher levels of disordered eating in pregnancy were significantly associated with higher levels of disordered eating at 6 weeks and 6 months postpartum, greater anxiety and depressive symptoms, lower 1-min Apgar scores, and abnormal birth weight.

DISCUSSION

The present study pointed to the need for more research and clinical attention to antenatal disordered eating given that it is associated with anxiety, depression, postpartum disordered eating and obstetric outcomes.

Prevalence of eating disorders over the 2000-2018 period: a systematic literature review

BACKGROUND

Eating disorders (EDs) lead to multiple psychiatric and somatic complications and thus constitute a major public health concern.

OBJECTIVES

The aim of this study was to give an exhaustive view of the studies reporting the prevalence of the different EDs or total EDs and to study their evolution.

METHODS

A literature search following PRISMA Guidelines and limited to studies in English or French published between 2000 and 2018 was performed and relevant studies were included in this systematic review on the prevalence of EDs. The literature search revealed 94 studies with accurate ED diagnosis and 27 with broad ED diagnosis.

RESULTS

In 94 studies with accurate ED diagnosis, the weighted means (ranges) of lifetime ED were 8.4% (3.3-18.6%) for women and 2.2% (0.8-6.5%) for men. The weighted means (ranges) of 12-month ED prevalence were 2.2% (0.8-13.1%) for women and 0.7% (0.3-0.9%) for men. The weighted means (ranges) of point prevalence were 5.7% (0.9-13.5%) for women and 2.2% (0.2-7.3%) for men. According to continents, the weighted means (ranges) of point prevalence were 4.6% (2.0-13.5%) in America, 2.2% (0.2-13.1%) in Europe, and 3.5% (0.6-7.8%) in Asia.In addition to the former, 27 other studies reported the prevalence of EDs as broad categories resulting in weighted means (ranges) of total point prevalence of any EDs of 19.4% (6.5-36.0%) for women and 13.8% (3.6-27.1%) for men.

CONCLUSIONS

Despite the complexity of integrating all ED prevalence data, the most recent studies confirm that EDs are highly prevalent worldwide, especially in women. Moreover, the weighted means of point ED prevalence increased over the study period from 3.5% for the 2000-2006 period to 7.8% for the 2013-2018 period. This highlights a real challenge for public health and healthcare providers.

Body dissatisfaction and disordered eating symptoms in Finnish preadolescents

To evaluate whether body dissatisfaction is associated with disordered eating symptoms in Finnish preadolescents, and to assess the moderator effects of gender and body mass index on this association. We included 10,526 9- to 12-year-old preadolescents at baseline from the Finnish Health in Teens cohort. We used the Children's Eating Attitudes Test for assessing disordered eating symptoms and a pictoral instrument for evaluating body dissatisfaction, comparing self-assessment of wanted and current body shape. Odds ratio (OR) for disordered eating symptoms were estimated using unconditional logistic regression. A high percentage of preadolescents reported body dissatisfaction: 30.0% wanted a smaller body and 9.3% wanted a larger body. Only 2.2% of the participants had disordered eating symptoms. Preadolescents who wanted a larger (OR = 2.83; 95% confidence intervals (CI): 1.68-4.78) or smaller body (OR = 4.48; 95% CI: 3.20-6.26) had a higher risk of having disordered eating symptoms, compared to preadolescents satisfied with their body. Among preadolescents who wanted a smaller body, the effect of body dissatisfaction was more pronounced among girls (OR = 5.00; 95% CI: 3.25-7.70) than boys, and among normal-weight (OR = 6.82; 95% CI: 4.53-10.25) and underweight (OR = 23.23; 95% CI: 5.31-101.61) than overweight preadolescents. Body dissatisfaction is associated with disordered eating symptoms especially among girls, and those who are underweight and normal-weight. Our study suggests that, in the prevention of eating disorders, special attention should be given to preadolescents with body dissatisfaction.

Eating symptomatology and general psychopathology in patients with anorexia nervosa from China, UK and Spain: A cross-cultural study examining the role of social attitudes

Cultural studies exploring differences in the manifestation of anorexia nervosa (AN) have primarily focus on Western and non-Western cultures. However, no study so far has considered the role that social attitudes (i.e. Collectivist vs. Individualist cultural values) have in the clinical manifestations of eating disorders, including AN patients. With this in mind, the aim of this study is to compare eating and general psychopathology in a large sample of individuals diagnosed with AN from China, Spain, and United Kingdom (UK), in order to study the differences according to belonging to Western or non-Western country, or the country's Individualist Index (IDV). The total sample comprised on 544 adults with a diagnosis of AN recruited from People´s Republic of China (n = 72), UK (n = 117), and Spain (n = 355). Assessment measures included the Eating Disorders Inventory and the Symptom Checklist-90-Revised. Our results show significant differences in most of the eating and psychopathological indices between the three countries. Patients from Western societies (Spain and UK) share more similarities regarding psychopathological expression of AN than the non-Western country (China). While Western countries show higher levels of body dissatisfaction, somatization and overall psychopathology, Chinese patients tend to deny or minimize depression, anxiety and other psychopathological symptoms. Besides, the IDV shows cultural differences in the interpersonal sensitivity scale, being AN patients from UK (the more individualistic society) who presented with higher levels of interpersonal sensitivity (i.e. discomfort during interpersonal interactions and more negative expectations concerning interpersonal behavior). In conclusion, our findings suggest that psychopathological expression of AN is better explained by Western/Eastern influence than by individualist/collectivist values. Although the diagnosis for the eating disorder may be the same, differences in the psychopathology comorbid to the eating disorders may suggest the need for treatments to be modified according to the culture.
