Gender differences in the pathway of childhood trauma, impulsivity and adult eating behaviour: a cross-sectional study

Objective: The current cross-sectional study aimed to examine the association between childhood trauma, impulsivity, binge eating symptoms, and body mass index (BMI) in a sample of males and females. We also aimed to investigate the indirect association of childhood trauma with binge eating through impulsivity while controlling for BMI.Method: Participants were 410 young adults (mean age = 20.9 years, range 18-24; female = 73.9%) who completed online measures of childhood trauma, impulsivity, binge eating symptoms, and self-reported height and weight. Mediation models were tested using multi-group structural equation modelling.Results: Childhood trauma and impulsivity were associated with an increased risk of binge eating symptoms in females but not males, corroborating previous studies. There was a significant difference in the binge eating symptoms index between sexes, but not regarding the index of childhood trauma and impulsivity. Additionally, adverse childhood experiences were associated with impulsivity and the association of childhood trauma with binge eating was mediated by impulsivity in the female sample.Conclusions: Our results suggest sex-dependent patterns and risk factors that may impact binge eating symptoms. The implications of our results suggest that impulsivity might be a vulnerability factor for binge eating, especially for females.

Risk of eating disorders, changes in salivary cortisol concentrations and nutritional status of adolescents

PURPOSE

The imposition of the thin body as an ideal of beauty and the changes that occur in adolescence lead to a constant concern with adolescents' body weight, putting them at risk for eating disorders. Thus, the study sought to investigate associations between eating disorders and salivary cortisol concentrations, nutritional status and depressive symptoms in female adolescents with bulimia.

METHODS

A cross-sectional study was carried out with 1435 adolescents aged 10-19 years. The Bulimic Investigatory Test of Edinburgh (BITE) and Body Shape Questionnaire (BSQ) questionnaires were used. A follow-up study was conducted from a random selection of female adolescents diagnosed with Bulimia Development and Well-Being Assessment-(DAWBA) to assess associations with salivary cortisol concentrations and nutritional status.

RESULTS

The prevalence of body dissatisfaction among adolescents with symptoms of bulimia was 37%. There was a significant difference between salivary cortisol and bulimia (Risk Group = 0.33 ± 0.20 μg/100 ml, Diagnostic Group = 0.44 ± 0.21 μg/100 ml p = 0.040), and correlation positive between the risk of bulimia with symptoms of depression (0.355 p = 0.002) and with Body Mass Index (0.259 p = 0.028). High concentrations of salivary cortisol in bulimic adolescents may be associated with hyperactivity of the hypothalamic-pituitary-adrenal axis and depressive symptoms.

CONCLUSIONS

Nutritional status indicators cannot be used alone for the diagnosis of bulimia, since cortisol levels seem to be a reliable parameter in the identification of bulimia, provided they are used with other diagnostic criteria.

Is work-family conflict a pathway between job strain components and binge eating? A cross-sectional analysis from the ELSA-Brasil study

BACKGROUND

Job strain has been reported as a trigger for binge eating, yet the underlying mechanisms have been unclear. The aim of this study was to evaluate whether work-family conflict is a pathway in the association between job strain and binge eating, considering the possible effect-modifying influence of body mass index (BMI).

METHODS

This cross-sectional analysis included 12,084 active civil servants from the multicenter Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Job strain was assessed using the Demand-Control-Support Questionnaire. Work-family conflict was considered as a latent variable comprising three items. Binge eating was defined as eating a large amount of food in less than 2 h at least twice a week in the last six months with a sense of lack of control over what and how much was eaten. Structural equation modelling was used to test the role of work-family conflict in the association between job strain and binge eating, stratifying for BMI.

RESULTS

For individuals of normal weight, positive associations were found between skill discretion and binge eating (standardized coefficient [SC] = 0.209, 95%CI = 0.022-0.396), and between psychological job demands and work-family conflict (SC = 0.571, 95%CI = 0.520-0.622), but no statistically significant indirect effect was found. In overweight individuals, psychological job demands, skill discretion, and work-family conflict were positively associated with binge eating (SC = 0.099, 95%CI = 0.005-0.193; SC = 0.175, 95%CI = 0.062-0.288; and SC = 0.141, 95%CI = 0.077-0.206, respectively). Also, work-family conflict was observed to be a pathway on the associations of psychological job demands and decision authority with binge eating (SC = 0.084, 95%CI = 0.045-0.122; and SC =  - 0.008, 95%CI =  - 0.015- - 0.001, respectively).

CONCLUSIONS

Work-family conflict partly explains effects of high levels of psychological job demands and low levels of decision authority on binge eating among overweight individuals. Moreover, skill discretion is positively associated with binge eating, regardless of BMI category.

Risk Behaviors for Eating Disorders Among Brazilian Female Adolescents

Background:

Eating disorders are complex conditions that cause serious emotional and physical problems.

Aim:

The aim of the study was to evaluate the behavioral risk for eating disorders in Brazilian female adolescents and their association with dental caries and erosion.

Materials and Methods:

This cross-sectional study included 200 students from public and private schools aged 15-18 years divided into two groups according to behavioral risk: Group 1 - adolescents without risk and Group 2 - adolescents at risk / disorder situation. Sociodemographic information (age and type of school), use of dental services, eating habits, and Body Mass Index (BMI) was obtained. The Bulimic Investigatory Test of Edinburgh (BITE) was used to identify behavioral risk. Caries experience was assessed using the DMFT index, while dental erosion was evaluated using the O'Sullivan index. Data were analyzed using descriptive and inferential statistics, with a significance level of 5%.

Results:

The highest overweight and obesity percentages were verified among adolescents at risk / disorder, respectively, 33% and 16%. There was a statistically significant association between behavioral risk and variables standard dietary pattern (p<0.001), strict diet (p<0.001), fasting for 24 hours (p<0.001), self-induced vomiting (p<0.001), and BMI (p<0.001). There was also a statistically significant difference between behavioral risk and the presence of dental caries (p<0.05) and erosion (p<0.001).

Conclusion:

Behavioral risk for eating disorders in female adolescents was associated with standard dietary patterns, strict diet and, self-induced vomiting. Adolescents at risk / eating disorders for bulimia were related to dental caries and erosion.

A controlled trial of a dissonance-based eating disorders prevention program with Brazilian girls

BACKGROUND

Given that most young women with eating disorders do not receive treatment, implementing effective prevention programs is a public health priority. The Body Project is a group-based eating disorder prevention program with evidence of both efficacy and effectiveness. This trial evaluated the efficacy of this prevention program with Brazilian girls, as no published study has tested whether this intervention is culturally sensitive and efficacious with Latin-American adolescents.

METHODS

Female students were allocated to a dissonance-based intervention (n = 40) or assessment-only (n = 22) condition. The intervention was a dissonance-based program, consisted of four group sessions aimed to reduce thin-ideal internalization. The sessions included verbal, written, and behavioral exercises. The intervention group was evaluated at pretest and posttest; assessment-only controls completed measures at parallel times.

RESULTS

Compared to assessment-only controls, intervention participants showed a significantly greater reduction in body dissatisfaction, sociocultural influence of the media, depressive symptoms, negative affect, as well as significantly greater increases in body appreciation. There were no significant effects for disordered eating attitudes and eating disorder symptoms.

CONCLUSIONS

These results suggest that this dissonance-based eating disorder prevention program was culturally sensitive, or at least culturally adaptive, and efficacious with Brazilian female adolescents. Indeed, the average effect size was slightly larger than has been observed in the large efficacy trial of this prevention program and in recent meta-analytic reviews.

Eating Attitudes, Weight Control Behaviors, Body Image Satisfaction and Depression Level Among Indian Medical and Nursing Undergraduate Students

This was a cross sectional descriptive study carried out among Medical and Nursing students to assess the presence of eating disorders. Data was collected using self administered 'Sick, Control, One, Fat, Food' (SCOFF) and 'Eating Attitudes Test (EAT-26)' questionnaires. It was found that 34.1% and 10.4% of the participants were at high risk to suffer from eating disorders on SCOFF and EAT-26 scales. Further, age, gender and education found to have significant association on SCOFF and EAT-26 scores (p < 0.05). Thus, the findings suggest the need for effective interventions to prevent depression and eating disorders among the future health professionals.

Temporal changes in the prevalence of disordered eating behaviors among adolescents living in the metropolitan area of Rio de Janeiro, Brazil

To investigate temporal changes in the prevalence of disordered eating behaviors among adolescents, and their association with socio demographic factors and overweight. Using probability sampling, two population-based cross-sectional surveys were conducted: one in 2005 (n=511) and the other in 2010 (n=314). The frequency of disordered eating behaviors (binge eating, strict dieting or fasting and compensatory behaviors) was investigated using a self-administered questionnaire. The presence of binge eating increased by 18.4% in the 5 years between the two surveys. In 2005, girls were 1.95 times more likely to engage in strict dieting or fasting than boys, and this difference increased to 7.02 times in 2010. Overweight adolescents were 2.29 times more likely to undertake strict dieting than non-overweight adolescents in 2005 and 3.65 times more likely to do so in 2010. No significant associations were found for compensatory behaviors. A pronounced increase in the prevalence of binge eating was observed, and girls and overweight adolescents were more likely to engage in strict dieting or fasting.

The job content questionnaire in various occupational contexts: applying a latent class model

OBJECTIVE

To evaluate Job Content Questionnaire(JCQ) performance using the latent class model.

METHODS

We analysed cross-sectional studies conducted in Brazil and examined three occupational categories: petroleum industry workers (n=489), teachers (n=4392) and primary healthcare workers (3078)and 1552 urban workers from a representative sample of the city of Feira de Santana in Bahia, Brazil. An appropriate number of latent classes was extracted and described each occupational category using latent class analysis, a multivariate method that evaluates constructs and takes into accountthe latent characteristics underlying the structure of measurement scales. The conditional probabilities of workers belonging to each class were then analysed graphically.

RESULTS

Initially, the latent class analysis extracted four classes corresponding to the four job types (active, passive, low strain and high strain) proposed by the Job-Strain model (JSM) and operationalised by the JCQ. However, after taking into consideration the adequacy criteria to evaluate the number of extracted classes, three classes (active, low strain and high strain) were extracted from the studies of urban workers and teachers and four classes (active, passive, low strain and high strain) from the study of primary healthcare and petroleum industry workers.

CONCLUSION

The four job types proposed by the JSM were identified among primary healthcare and petroleum industry workers-groups with relatively high levels of skill discretion and decision authority. Three job types were identified for teachers and urban workers; however, passive job situations were not found within these groups. The latent class analysis enabled us to describe the conditional standard responses of the job types proposed by the model, particularly in relation to active jobs and high and low strain situations.

Job strain and binge eating among Brazilian workers participating in the ELSA-Brasil study: does BMI matter?

Objective:

To assess the association between job strain and binge eating as well as the effect-modifying influence of body mass index (BMI) on this association.

Methods:

A total of 11,951 active civil servants from the multicenter Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) was included in this cross-sectional analysis. Job strain was assessed using the Demand-Control-Support Questionnaire. Binge eating was defined as eating a large amount of food with a sense of lack of control over what and how much is eaten in less than 2 hours at least twice a week. Multiple logistic regression was used to determine the association between binge eating and job strain as well as its interaction with BMI.

Results:

After adjustment, and using low-strain job as the reference category, binge eating was associated with high-strain job (high demand/low control: odds ratio [OR]=1.58, 95% confidence interval [CI] 1.26-1.98), active job (high demand/high control: OR=1.35, 95% CI 1.07-1.70), and passive job (low demand/low control: OR=1.24, 95% CI 1.01-1.53). Psychological job demands were positively associated with binge eating (OR=1.04, 95% CI 1.01-1.07), while greater job control and social support at work were each inversely associated with binge eating (OR=0.95, 95% CI 0.92-0.97 and OR=0.96, 95% CI 0.94-0.98, respectively). BMI modified the association between job strain and binge eating: Heavier psychological job demands were associated with higher odds of binge eating among obese participants, while a stronger inverse association between job control and binge eating was seen among slimmer participants.

Conclusions:

Job strain increases the odds of binge eating and this association is modified by BMI.

Adaptação transcultural para o português dos Questionários de Desejos Intensos por Comida – Estado ou Traço (QDIC-E e QDIC-T) dos State and Trait Food-Cravings Questionnaires (FCQ-S and FCQ-T)

Resumo Este estudo objetivou apresentar a adaptação transcultural dos Questionários de Desejos Intensos por Comida – Estado ou Traço (QDIC-E e QDIC-T) dos State and Trait Food-Cravings Questionnaires (FCQ-S and FCQ-T) para o Português. Fez-se a tradução e a retradução dos instrumentos, a avaliação da equivalência conceitual, operacional e de itens por especialistas da área e a avaliação dos instrumentos por uma amostra de universitários, por meio da avaliação do grau de compreensão e análise da consistência interna dos instrumentos pelo coeficiente Alpha de Cronbach. Ademais, fez-se a avaliação da equivalência semântica pelo coeficiente de correlação intraclasse entre os escores obtidos por bilíngues em cada questão das versões em inglês e português. Os instrumentos foram considerados de fácil compreensão (para os especialistas foi de 95,4% e 97%, para o QDIC-T e QDIC-E, respectivamente, e, para os universitários, 81,8% os consideraram de fácil compreensão), e demonstraram valores de consistência interna satisfatórios (QDIC-T: variaram de 0,6 a 0,8; QDIC-E: variaram de 0,5 a 0,8). A partir do processo de adaptação transcultural, os resultados satisfatórios possibilitam a recomendação da versão brasileira dos QDICs.

Association of binge eating behavior and psychiatric comorbidity in ELSA-Brasil study: Results from baseline data

OBJECTIVE

To estimate the association of binge eating behavior (BE) with common mental disorders (CMD).

METHOD

Cross sectional investigation of 14,088 adults, aged 35-74years (ELSA-Brasil study). BE was assessed with Structured Clinical Interview for DSM Disorders (SCID - DSM IV) questions, and psychiatric morbidity with CIS-R (CIS R - Clinical Interview Schedule Revised). Poisson regression was used to estimate the association of BE and psychiatric morbidity.

RESULTS

Adjusted prevalence ratios (PR) for CMD and BE were: PR=1.60 (1.34-1.91) for a CIS R score 12-18 (presence of CMD with lower clinical severity); PR=2.40 (2.06-2.80) for a CIS R score≥18 (severe symptom profile likely to require treatment); for psychiatric diagnoses: PR=2.24 (1.84-2.73) for depressive episodes; PR=1.77 (1.53-2.04) for anxiety disorders, and PR=1.42 (1.20-1.67) for mixed depressive-anxiety disorder.

CONCLUSION

BE was associated with higher prevalence of common mental disorders. Our findings highlight the need to investigate mechanisms involved in the relationship of BE, obesity and psychopathology in low/middle income countries.

Binge eating, sociodemographic and lifestyle factors in participants of the ELSA-Brazil

BACKGROUND

This study investigates the relationship between recurrent binge eating episodes and nutritional and food profiles and lifestyle in the Brazilian Longitudinal Study of Adult Health (Estudo Longitudinal da Saúde do Adulto - ELSA-Brazil) cohort.

RESULTS

Recurrent binge eating episodes were associated with obesity (OR 5.188; confidence interval [CI] 4.051-6.645), overweight (OR 2.534; CI 1.980-3.243), female sex (OR 1.918; CI 1.573-2.338), age between 34 and 54 years old (OR 1.349; CI 1.115-1.631), alcohol ingestion ≥ 5 in two hours (OR 1.397; CI 1.068-1.827), and insufficient physical activity (OR 1.290; CI 1.078-1.544).

CONCLUSION

Being overweight has an important association with recurrent binge eating episodes, as does demographic and lifestyle characteristics, including excessive alcohol consumption.

Internal consistency of the self-reporting questionnaire-20 in occupational groups

OBJECTIVE

To assess the internal consistency of the measurements of the Self-Reporting Questionnaire (SRQ-20) in different occupational groups.

METHODS

A validation study was conducted with data from four surveys with groups of workers, using similar methods. A total of 9,959 workers were studied. In all surveys, the common mental disorders were assessed via SRQ-20. The internal consistency considered the items belonging to dimensions extracted by tetrachoric factor analysis for each study. Item homogeneity assessment compared estimates of Cronbach’s alpha (KD-20), the alpha applied to a tetrachoric correlation matrix and stratified Cronbach’s alpha.

RESULTS

The SRQ-20 dimensions showed adequate values, considering the reference parameters. The internal consistency of the instrument items, assessed by stratified Cronbach’s alpha, was high (> 0.80) in the four studies.

CONCLUSIONS

The SRQ-20 showed good internal consistency in the professional categories evaluated. However, there is still a need for studies using alternative methods and additional information able to refine the accuracy of latent variable measurement instruments, as in the case of common mental disorders.

Relacionamentos Afetivo-Familiares em Mulheres com Anorexia e Bulimia

RESUMO Este estudo teve por objetivo investigar a rede social de apoio de mulheres com anorexia e bulimia, com ênfase em suas relações afetivo-familiares. A amostra foi composta por 12 participantes atendidas em hospital universitário. Os instrumentos utilizados foram: roteiro de entrevista semiestruturada, Mapa de Rede e Genograma. Os resultados indicaram que as redes sociais das participantes têm configuração restrita, com proeminência de membros da família em sua composição. Os relacionamentos familiares oscilam, contudo, entre turbulência e distanciamento afetivo. As relações de afeto mantidas com pais, cônjuges e namorados são marcadas por divergências e insatisfações. A baixa densidade da rede de amizades e o empobrecimento da vida social resultam em isolamento e dificuldades de dar início e/ou manter relacionamentos afetivos duradouros.

Efeitos de diversos fatores sobre o comportamento alimentar de adolescentes

Pesquisadores sugerem que o comportamento alimentar inadequado (CAI) em jovens pode sofrer influências de diversos fatores. No entanto, os resultados têm sido controversos. Deste modo, o objetivo do presente estudo foi averiguar os efeitos de insatisfação corporal (IC), grau de comprometimento psicológico ao exercício (GCPE), nível habitual de atividade física (NAF), índice de massa corporal (IMC), percentual de gordura e etnia sobre o CAI de adolescentes. Participaram 362 jovens de ambos os sexos com idades entre 10 e 19 anos. O Eating attitudes test (EAT-26) foi utilizado para avaliar o CAI. Ademais, utilizou-se o Body shape questionnaire, a commitment exercise scale e o International physical activity questionnaire para avaliar IC, GCPE e NAF, respectivamente. Conduziu-se análise multivariada e regressão múltipla para analisar os dados. Os resultados evidenciaram que a IC, o GCPE, IMC e percentual de gordura influenciaram significativamente (p < 0,05) os escores das subescalas do EAT-26, tanto no sexo feminino, quanto no masculino. No entanto, os efeitos das variâncias foram diferentes entre os sexos. Concluiu-se que IC e o IMC foram os principais fatores que promoveram efeitos significativos nos distintos construtos do comportamento alimentar avaliados pelo EAT-26 em ambos os sexos.
