Overweight and eating disorders in primary care: a sentinella reporting in 2-20 years old patients

Aims: To describe overweight or eating disorders in primary care consultations of Swiss children or adolescents and analyze responses by physicians. Methods: 150 to 200 primary care physicians participating in the Swiss Sentinel Surveillance Network in collaboration with the Swiss Federal Office of Public Health register their consultations over one year for selected health conditions. We describe reports of consultations where overweight or eating disorders were identified in subjects aged 2-20 years by physicians, patients or their relatives, or referring professionals, between 29.12.2007 and 15.2.2008. Results: 189 consultations were registered in the first 7 weeks of declaration. A short majority concerned female (58%) and 12-20 years old (53%) patients. Half were reported by pediatricians, one third by general practitioners and the remaining minority by internists. The sample included two thirds of Swiss-German and one third of Swiss-French cases. In the male subgroup aged 2-20 and in female children aged 2-11, almost all reported consultations were characterized by overweight. Among female teenagers, underweight was reported in 29% whilst overweight was recorded in 60%. Anorexia was noted in 68% of reported consultations of underweight female teenagers. In underweight patients, advice given by physicians frequently covered both nutrition and physical activity (38%) or nutrition only (29%), while no specific recommendations were recorded for the remaining third. In case of overweight, for one half of consultations patients received both nutritional and physical activity recommendations, for 12% nutritional only, and for one quarter patients were not advised in these domains. No specific treatment was usually proposed to overweight patients (65%), except when bulimia was diagnosed; in such case, one third of patients were proposed a psychological/psychiatric treatment, whereas both psychological and pharmacological treatments were frequently offered for underweight teenagers. Therapy was most often motivated by physicians (50%) or by relatives (44%), more rarely by patients themselves (7%). Conclusions: These preliminary data indicate that in some primary care consultations of young patients with overweight or eating disorders, advice was not given on nutrition and physical activity. This observation needs to be later confirmed with the totality of the consultations registered in 2008 and reasons will be further investigated.

Independent contribution of parental migrant status and educational level to adiposity and eating habits in preschool children.

Background/Objective:Little is known about the precise role of parental migrant status (MS) and educational level (EL) on adiposity and various eating habits in young children. Therefore, we assessed their independent contribution in preschoolers.Subjects/Methods:Of 655 randomly selected preschoolers, 542 (5.1±0.6 years; 71% of parental MS and 37% of low parental EL) were analysed. Body composition was measured by bioelectrical impedance. Eating habits were assessed using a semiqualitative food frequency questionnaire and analysed according to five messages developed by the Swiss Society for Nutrition, based on factors implicated in childhood obesity: (1) 'Drinking water and decreasing sweetened drinks', (2) 'Eating fruit and vegetables', (3) 'Decreasing breakfast skipping', (4) 'Reducing fatty and sweet foods' and (5) 'Reducing the intake of meals and snacks in front of television'.Results:Children of migrant and low EL parents had higher body fat, ate more meals and snacks while watching television and had more fruit and fatty foods compared with their respective counterparts (all P0.04). Children of low EL parents also consumed less water and vegetables compared with their counterparts (all P0.04). In most instances, we found an independent contribution of parental MS and EL to adiposity and eating habits. A more pronounced effect was found if both parents were migrants or of low EL. Differences in adiposity and eating habits were relatively similar to the joint parental data when assessed individually for maternal and paternal MS and EL.Conclusions:Parental MS and EL are independently related to adiposity and various eating habits in preschoolers.European Journal of Clinical Nutrition advance online publication, 3 November 2010; doi:10.1038/ejcn.2010.248.

Influence des habitudes alimentaires sur la morbidité chez 645 patients obèses d'une consultation spécialisée. [Effect of eating habits on morbidity in 645 patients at a specialized clinic].

Among 645 obese patients examined at an out-patient clinic for obese patients by physical examination and a computerized questionnaire, two subgroups of patients could be identified according to their nutritional preferences: 177 patients preferred carbohydrates exclusively (group A) and 73 patients fat exclusively (group B). No definite preferences were formulated by the other patients. Among patients under 25 years, only 3 belonged to group B and 49 to group A, while in older patients no significant differences were found. Among patients with BMI less than 30, there were significantly fewer patients from group B than from group A (p = 0.006), while in patients with BMI greater than 30 no significant difference was observed. There were significantly more men in group B than in group A. 57% of the patients of group B complained of physical symptoms related to their obesity, compared to 37% in group A (p = 0.006). 26% of group B suffered from joints and muscles compared to 13% of group A (p = 0.003). Hyperglycemia (greater than 5,6 mmol/l) was found in 21% of group A and in 40% of group B (p less than 0.005). Hypercholesterolemia (greater than 6.5 mmol/l) was found in 20% of group A and in 32% of group B (p less than 0.05). In conclusion, obese patients who prefer fat have more general symptoms related to obesity, more abnormal physical signs, and more frequently have hyperglycemia and hypercholesterolemia than patients who prefer carbohydrates.

Médecine de l'adolescence : troubles des conduites alimentaires atypiques [Adolescent medicine : eating disorders not otherwise specified (EDNOS)]

Young people (mostly females) suffering from eating disorders not otherwise specified (EDNOS) are more and more numerous and their difficulties pose serious problems to health care providers as well as the society. These situations correspond to eating disorders which do not totally meet the DSM-IV criteria for either anorexia or bulimia nervosa. The duration of the symptoms, the extent of suffering as well as the impact on daily life should be taken into account to set-up the treatment. The therapeutic approach to these disorders should ideally include both cognitive/dietary and psychodynamic approaches. The Multidisciplinary Unit for Adolescent Health in Lausanne has set-up a group treatment for these patients.

Genetic Association of Recovery from Eating Disorders: The Role of GABA Receptor SNPs.

Follow-up studies of eating disorders (EDs) suggest outcomes ranging from recovery to chronic illness or death, but predictors of outcome have not been consistently identified. We tested 5151 single-nucleotide polymorphisms (SNPs) in approximately 350 candidate genes for association with recovery from ED in 1878 women. Initial analyses focused on a strictly defined discovery cohort of women who were over age 25 years, carried a lifetime diagnosis of an ED, and for whom data were available regarding the presence (n=361 ongoing symptoms in the past year, ie, 'ill') or absence (n=115 no symptoms in the past year, ie, 'recovered') of ED symptoms. An intronic SNP (rs17536211) in GABRG1 showed the strongest statistical evidence of association (p=4.63 × 10(-6), false discovery rate (FDR)=0.021, odds ratio (OR)=0.46). We replicated these findings in a more liberally defined cohort of women age 25 years or younger (n=464 ill, n=107 recovered; p=0.0336, OR=0.68; combined sample p=4.57 × 10(-6), FDR=0.0049, OR=0.55). Enrichment analyses revealed that GABA (γ-aminobutyric acid) SNPs were over-represented among SNPs associated at p<0.05 in both the discovery (Z=3.64, p=0.0003) and combined cohorts (Z=2.07, p=0.0388). In follow-up phenomic association analyses with a third independent cohort (n=154 ED cases, n=677 controls), rs17536211 was associated with trait anxiety (p=0.049), suggesting a possible mechanism through which this variant may influence ED outcome. These findings could provide new insights into the development of more effective interventions for the most treatment-resistant patients.

Disordered eating behaviors: what about boys?

PURPOSE: To determine the characteristics specific to boys with disordered eating behaviors (DEB) and the general context in which these DEB occur. METHOD: Data were drawn from the SMASH02 database, a survey carried out among post-mandatory school students in Switzerland aged 16-20 years in 2002. Only males (N=3890) were included, and were classified into into one of four groups based on their level of concern about weight/food and on their eating behaviors, as follows: group 1: one concern without behavior (N=862); group 2: more than one concern without behavior (N=361); group 3: at least one behavior (N=798); and a control group (N=1869), according to previously validated items. Groups were compared for personal, family, school, experience of violence, and health-compromising behaviors variables on the bivariate level. All significant variables were included in a multinomial logistic regression using Stata 9 software. RESULTS: About one-half of the boys reported either a concern or unhealthy eating behavior. Compared with the control group, boys from the three groups were more likely to be students and to report a history of sexual abuse, delinquency, depression, and feeling fat. In addition, boys from group 3 were more likely to report a history of dieting, early puberty, peer teasing, having experienced violence, frequent inebriation, and being overweight. CONCLUSION: DEB concern adolescent males more frequently than thought and seem to be integrated in a general dysfunctional context, in which violence is predominant. Adolescent males also need to be screened for DEB. Moreover, prevention programs should target the increasing social and media pressure regarding boys ideal body shape and raise public consciousness about this phenomenon.

Alexithymia and depression in eating disorders.

We compared alexithymia and depression ratings for non-hospitalized women meeting DSM-IV criteria for anorexia nervosa (n=32) and bulimia nervosa (n=32) to ratings for healthy women (n=74). Alexithymia was evaluated by the Toronto Alexithymia Scale (TAS-20) and depression by the Hospital Anxiety and Depression Scale (HAD). TAS and HAD scores were significantly higher in anorexic compared to bulimic patients, although these two scales were significantly and positively correlated (r=0.53, P=0.001). After taking depression into account as a confounding variable, rates of alexithymia did not vary according to the type of eating disorder (anorexia or bulimia).

Assessment of emotional reactivity produced by exposure to virtual environments in patients with eating disorders

The aim of this study was to assess the usefulness of virtual environments representing situations that are emotionally significant to subjects with eating disorders (ED). These environments may be applied with both evaluative and therapeutic aims and in simulation procedures to carry out a range of experimental studies. This paper is part of a wider research project analyzing the influence of the situation to which subjects are exposed on their performance on body image estimation tasks. Thirty female patients with eating disorders were exposed to six virtual environments: a living-room (neutral situation), a kitchen with highcalorie food, a kitchen with low-calorie food, a restaurant with high-calorie food, a restaurant with low-calorie food, and a swimming-pool. After exposure to each environment the STAI-S (a measurement of state anxiety) and the CDB (a measurement of depression) were administered to all subjects. The results show that virtual reality instruments are particularly useful for simulating everyday situations that may provoke emotional reactions such as anxiety and depression, in patients with ED. Virtual environments in which subjects are obliged to ingest high-calorie food provoke the highest levels of state anxiety and depression.

Cognitive behavioural therapy for obesity and binge eating associated to antipsychotic drugs

Background and Aims: Overweight, obesity and binge eating disorder are commonly reported in persons with severe mental disorders. Particularly, antipsychotic drugs (AP) induce weight gain in up to half of the patients. The aim of the present study is to confirm a previous study results on a larger sample of patients, to assess the impact of the interventions on other relevant dimensions of eating and weight related cognitions as well as to assess potential clinical indicators of outcomes such as AP drug, concomitant treatment with lithium or carbamazepine, psychiatric diagnostic, binge eating and severity of cognitive distortions. Method: A controlled study (12-week CBT vs. B N E) was carried out on 99 patients treated with an AP and who have gained weight following this treatment. Binge eating symptomatology, eating and weight-related cognitions, as well as weight and body mass index were assessed before treatment, at 12 weeks and at 24 weeks. Results: The findings confirms usefulness and effectiveness of the proposed CBT program on the treatment of binge symptomatology, cognitive distortions and obesity in patients treated with AP. Reduction of binge symptoms and maladapted cognitions appeared early, whereas the effect on weight appeared later during the follow up observation. No differences on outcomes were found across pharmacotherapy characteristics, diagnostic categories, binge eating nor severity of cognitive distortions. Conclusion: The proposed CBT treatment is useful for patients suffering from weight gain associated with AP treatments indeed when a concomitant treatment with lithium or valproate was given.

Effect of orlistat in obese patients with binge eating disorder.

OBJECTIVE: Binge eating disorder represents a significant public health problem, with up to 50% of weight loss program participants displaying this disorder. In previous studies with orlistat, patients with binge eating disorder were excluded. The goal of this study was to assess the efficacy of orlistat in obese patients with binge eating disorder. RESEARCH METHODS AND PROCEDURES: Eighty-nine patients with clinically diagnosed binge eating disorder and a BMI > or = 30 kg/m2 were randomized in double-blind fashion to 24 weeks of treatment with 120 mg of orlistat or placebo three times daily, in combination with a mildly reduced-calorie diet. RESULTS: After 24 weeks, the mean weight loss from baseline for orlistat-treated patients was significantly greater than for patients receiving placebo (-7.4% vs. -2.3%; p = 0.0001) (intent-to-treat analysis). The overall Eating Disorder Inventory 2 score at week 24 was significantly lower in patients treated with orlistat than in those in the placebo group (p = 0.011). DISCUSSION: Orlistat may be considered as part of the management for patients with obesity and binge eating disorder.

Self-Construction, Cognitive Conflicts, and Disordered Eating Attitudes in Young Women

The aim of this study is to identify cognitive variables that predict disordered eating attitudes in a nonclinical sample composed of 50 female university students. Repertory grid technique was used to assess cognitive features of self-construing and cognitive conflicts. Drive for Thinness and Body Dissatisfaction scales from the Eating Disorder Inventory 2 were used as dependent variables, as previous studies suggested that high scores on these scales are associated with the risk of developing or aggravating eating syndromes. Results suggest that drive for thinness can be associated with cognitive conflicts, whereas body dissatisfaction may be higher for those who construct themselves as inadequate and similar to others. In addition, both dependent variables were predicted by being younger and having a higher body mass index.
