- We addressed the question of whether a combination of obesity and hyperandrogenicity has a more severe influence on psychosocial behaviours, as reflected by eating behaviour and body image, compared to obesity alone. AIM: To study eating behaviour and body image in age-, pubertal- and BMI-matched overweight adolescent girls with and without hyperandrogenicity, and to compare the data with those from a control group of normal weight girls. METHODS: Overweight adolescent girls in late puberty with (n=10) and without hyperandrogenicity (n=8) and a control group of normal weight girls (n=9) were studied. The Eating Disorder Inventory for children (EDI-C) questionnaire was used to obtain information on eating behaviours and psychological characteristics, and silhouettes were used to evaluate body image. RESULTS: The girls with overweight but without hyperandrogenicity showed more disturbed eating behaviour and more psychological problems than did the girls with both overweight and hyperandrogenicity as compared to the healthy controls. The overweight group also had more feelings of ineffectiveness than the hyperandrogenic group. Both the overweight and the hyperandrogenic girls estimated themselves as being significantly larger and their ideal shape as being significantly smaller than their Current shape. However, all overweight girls considered their Current shape to be significantly smaller than it was objectively. CONCLUSIONS: The girl With overweight alone seemed to have more disturbed eating behaviour and more psychological problems than girls with combined overweight and hyperandrogenicity. This could indicate that different therapeutic interventions might be needed in attempts to reduce weight in the two groups.

Reasons for non-participation in follow-up research on eating disorders

- OBJECTIVE: Lack of participation in follow-ups is thought to be a serious bias in outcome research on eating disorders; however, little systematic knowledge exists about the problem. The present study aimed to delineate non-participation in long-term follow-up research, and explore the reasons for non-participation.METHOD: Eating disorder patients (N=840) entering a naturalistic, longitudinal multi-centre study were divided into participators (N=508) and non-participators (N=332) in 36-month follow-ups. Non-participators were further classified as either active (i.e. refused participation or failed to attend scheduled appointments) or passive non-participators (i.e. could not be traced).RESULTS: Active non-participators exhibited significantly lower levels of general and eating disorder psychopathology at intake compared to participators, while passive non-participators reported higher levels of hostility.DISCUSSION: Systematic exploration of non-participation in longitudinal research can help to mitigate the problem of indistinct results due to missing data. Barriers to successful longitudinal research and how to overcome non-participation at endpoint are discussed.

Physical activity in treatment units for eating disorders : Clinical practice and attitudes
- 2009

- OBJECTIVE: Physical activity (PA) in eating disorders (ED) may be harmful, but in a therapeutic setting also beneficial. The purpose of this survey was to examine these contradictory aspects of PA in ED specialist treatment settings. We examined whether 1) PA is assessed by the unit, 2) the units have guidelines for managing excessive PA, 3) the units have staff with higher education and special competence in PA and exercise science, 4) how units regard PA in ED, 5) whether regular PA is integrated in the treatment programs, and 6) how the units rate the role of PA in the treatment of ED compared with other mental disorders. METHODS: Of the 49 units located in Scandinavia and the United Kingdom, 41 (84%) responded to a questionnaire. RESULTS: In 28 units (68%) PA was assessed regularly. Excessive PA was considered a harmful symptom in ED, and most units reported guidelines to manage excessive PA. Thirty-two units included PA in their treatment programmes. Clinicians found PA most relevant in the treatment of obesity and, except for binge eating, less for ED. CONCLUSION: PA was more commonly integrated in treatment compared to previous studies. Future research should address how to manage excessive PA, and the potential beneficial role of PA in the treatment of ED. (Eating Weight Disord. 14: e106-e112, 2009). (C) 2009, Editrice Kurtis

Directly measured free 25-hydroxy vitamin D levels show no evidence of vitamin D deficiency in young Swedish women with anorexia nervosa

- Purpose Anorexia nervosa (AN) is an eating disorder characterized by low fat mass complicated by osteoporosis. The role of circulating vitamin D in the development of bone loss in AN is unclear. Fat mass is known to be inversely associated with vitamin D levels measured as serum levels of total, protein-bound 25-hydroxyvitamin D, but the importance of directly measured, free levels of 25(OH)D has not been determined in AN. The aim of this study was to investigate vitamin D status, as assessed by serum concentrations of total and free serum 25(OH)D in patients with AN and healthy controls. Methods In female AN patients (n = 20), and healthy female controls (n = 78), total 25(OH)D was measured by LC-MS/MS, and free 25(OH)D with ELISA. In patients with AN bone mineral density (BMD) was determined with DEXA. Results There were no differences between patients and controls in total or free S-25(OH)D levels (80 +/- 31 vs 72 +/- 18 nmol/L, and 6.5 +/- 2.5 vs 5.6 +/- 1.8 pg/ml, respectively), and no association to BMD was found. In the entire group of patients and controls, both vitamin D parameters correlated with BMI, leptin, and PTH. Conclusions The current study did not demonstrate a vitamin D deficiency in patients with AN and our data does not support vitamin D deficiency as a contributing factor to bone loss in AN. Instead, we observed a trend toward higher vitamin D levels in AN subjects compared to controls. Measurement of free vitamin D levels did not contribute to additional information.

Forskningsöversikt (refereegranskat)abstract
- Purpose Cognitive restraint has potentiating and deleterious effects on working memory (WM) in anorexia nervosa (AN). Conflicting evidence may be due to heterogeneity of tasks examining different WM components (e.g., verbal/auditory versus visuospatial), and differences in adolescent versus adult AN. Additionally, differential cognitive profiles of restricting versus binge/purging subtypes, comorbid psychiatric disorders and psychotropic medication use may confound findings.Methods To address these conflicts, 25 studies, published between 2016 and 2021, investigating WM in children, adolescents and adults with AN were systematically reviewed using PRISMA guidelines.Results In 71% of WM tasks, no difference in performance between AN patients and age-matched controls was reported, while 29% of WM tasks showed worse performance. Adults with AN displayed deficits in 44% of the verbal/auditory tasks, while performance remained unaffected in 86% of visuospatial tasks.Conclusion Examining age groups and WM subsystems separately revealed novel findings of differentially affected WM components in AN. Comorbidities and psychotropic medications were common among AN participants and should be regarded as critical confounding factors for WM measures. Future studies examining different components of WM, acknowledging these confounding factors, may reveal specific deficits in AN to aid treatment improvement strategies.
