Knowledge of eating disorders in young and adolescent males is sparse. To investigate clinical presentations in males and females with anorexia nervosa (AN). Using a retrospective case-control design, data were collected from case records for 41 males diagnosed with AN. Data for a comparison group of 41 females with AN were collected, matched to the males by age and date at admission. The collected data covered demographic, medical, psychiatric, and treatment information. No differences were found between the sexes in the percentage of expected weight (%EBW) at admission or discharge, or in psychiatric comorbidity. Treatment duration was equal for both sexes, but males received fewer treatment sessions than did females. These results indicate that the clinical presentations of young males and females with AN were very similar in terms of clinical characteristics. What is already known about this subject? Research on AN in male children and adolescents is sparse. Previous studies comparing male and female patients with EDs have found both differences and similarities between sexes. What does this study add? This study found few differences in terms of clinical presentation of AN between the sexes. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic, associated with confinement and social isolation, seems to have impacted the course of many mental disorders in children and adolescents. An increase in hospital admission rates for juvenile anorexia nervosa (AN) has been documented in many regions of the world. However, data from Europe are scarce. Methods: We asked clinicians in specialized eating disorder units in hospitals of maximum care in France, Germany, Italy, Spain, Sweden, and the Netherlands to report on (i) overall (inpatient and outpatient) and (ii) inpatient admission rates for adolescents with AN during 2019 and 2020. Additionally, a modified version of the COVID Isolation Eating Scale (CIES) was used to assess the child and adolescent psychiatrists' estimations of a possible increase in symptom severity in children and adolescents with AN during the COVID-19 pandemic and to (iii) inquire about the contributing factors perceived by the caring professionals. Results: Four out of six representatives of European hospitals described a higher rate of overall admissions during the pandemic. Three hospitals out of six reported an increase in inpatient admissions, and two centres had constant high numbers of admissions of both outpatients and inpatients. The clinicians perceived a higher symptom severity in 2020 than in 2019, especially involving more frequent use of social media, longer duration of exercising, and more restrictive eating. They supposed an increase in social media consumption, a perceived "loss of control", and a lack of in-person assessments and weight controls as the main contributing factors for the deterioration in AN numbers and symptomatology. Conclusions: The COVID-19 pandemic seems to have had a deep impact on symptom severity in AN, which is mirrored by a large increase in admission rates across Europe. An increase in exercise, social media consumption, a perceived "loss of control", and a lack of face-to-face health care seem to have contributed to this development. Further investigation is required to identify which factors may lead to the increase in incidence and deterioration of childhood and adolescent AN. Possible preventive means for the future could include educating paediatricians and health care workers about AN, regular weight assessment, and home-based treatments. [ABSTRACT FROM AUTHOR]

Background: Little is known about the long-term outcome of anorexia nervosa.Aims: To study the 30-year outcome of adolescent-onset anorexia nervosa.Method: All 4291 individuals born in 1970 and attending eighth grade in 1985 in Gothenburg, Sweden were screened for anorexia nervosa. A total of 24 individuals (age cohort for anorexia nervosa) were pooled with 27 individuals with anorexia nervosa (identified through community screening) who were born in 1969 and 1971-1974. The 51 individuals with anorexia nervosa and 51 school- and gender-matched controls were followed prospectively and examined at mean ages of 16, 21, 24, 32 and 44. Psychiatric disorders, health-related quality of life and general outcome were assessed.Results: At the 30-year follow-up 96% of participants agreed to participate. There was no mortality. Of the participants, 19% had an eating disorder diagnosis (6% anorexia nervosa, 2% binge-eating disorder, 11% other specified feeding or eating disorder); 38% had other psychiatric diagnoses; and 64% had full eating disorder symptom recovery, i.e. free of all eating disorder criteria for 6 consecutive months. During the elapsed 30 years, participants had an eating disorder for 10 years, on average, and 23% did not receive psychiatric treatment. Good outcome was predicted by later age at onset among individuals with adolescent-onset anorexia nervosa and premorbid perfectionism.Conclusions: This long-term follow-up study reflects the course of adolescent-onset anorexia nervosa and has shown a favourable outcome regarding mortality and full symptom recovery. However, one in five had a chronic eating disorder. [ABSTRACT FROM AUTHOR]

ABSTRACT Objective Although weight history is relevant in predicting eating disorder symptom severity, little is known about its role in the etiology of anorexia nervosa (AN). This study aimed to determine whether BMI or BMI trajectory differed between individuals who later developed adolescent-onset AN and a comparison group of HCs between school grades 1 through 6. Method This study was based on longitudinal data that identified 51 adolescents with AN and 51 matched HCs. Cases were identified through community screening in Sweden and included individuals born in 1969 through 1977. Measured weights and heights were retrieved and BMIs and weight trajectories of the AN and HC groups were compared using growth curve analysis. Main outcome measures included measured BMI and BMI trajectories from grades 1-6. Secondary outcomes examined included ponderal index at birth and maternal body weight. Results Individuals who later developed AN had higher BMIs than HCs between grades 1 and 6, by an average of 1.42 BMI-units. There was no difference in rate of weight gain between groups. Ponderal index at birth was higher for the AN as compared with HC group. Maternal weight did not differ significantly between groups. Discussion These findings, combined with those previously reported on the premorbid BMIs of those with bulimia nervosa, suggest that a predisposition toward elevated premorbid BMIs during childhood characterizes those who later develop anorexia or bulimia nervosa. These findings are consistent with a transdiagnostic perspective and suggest shared risk factors for AN and obesity. © 2016 Wiley Periodicals, Inc.

Objective To follow up bone mineral density (BMD) 4 years after decreased BMD was diagnosed in adult individuals with teenage-onset anorexia nervosa (AN). Method In a previous study BMD was assessed in 39 individuals (36 women, 3 men) 11 years after AN onset. Decreased BMD occurred in a minority. In the present study, a 4-year follow-up of individuals with decreased BMD, 11 AN women were reassessed by using dual energy X-ray absorptiometry (DXA). Two women still had an eating disorder (ED). Results Eight out of eleven women met criteria for decreased BMD/osteoporosis. There was an increase in BMD of total body and lumbar spine (LS). There was a relationship between lumbar BMD and BMI. Conclusion At follow-up of decreased BMD in adult women with teenage-onset of AN, there is a possibility of improvement of BMD. © 2007 John Wiley & Sons, Ltd and Eating Disorders Association.

In a longitudinal study, the authors explore the course of general cognition in anorexia nervosa (AN) over time and compare general cognitive problems, executive function deficits, attentional problems and visuomotor dysfunctions across AN individuals and healthy controls. A community-based sample of adolescent onset AN cases (n = 40–47) was contrasted with an age-, sex- and school matched comparison group (n = 47–51) on the Wechsler Adult Intelligence Scale-Revised, the Wisconsin Card Sorting Test and Luria word recall test at a mean age of 24 years. Only two of the cases tested were underweight at the time of the study. The Wechsler scale had also been administered when the groups had a mean age of 21 years. There were few differences across the two groups even though the comparison group performed significantly better on the Object Assembly subtest of the WAIS-R. IQ increased slightly but significantly over time in both groups. There was no relationship between level of starvation and poor results on tests in the AN group. A subgroup of the subjects had autism spectrum disorders. In this subgroup there were cases with test profiles similar to those observed in autism and Asperger syndrome, just as there had been on testing three years previously. Ten years after AN onset, the former AN cases showed no major neuropsychological deficits. A subgroup with autistic features had test profiles similar to those observed in autism spectrum disorders. The AN group as a whole showed poor results on the object assembly subtest indicating weak central coherence with a tendency to focus on details at the expense of configural information. This cognitive style may account for their obsession with details, with implications for psychoeducational approaches in treatment programmes/interventions. [ABSTRACT FROM AUTHOR]

Objective We studied fertility and history of child sexual abuse (CSA) in a representative group of anorexia nervosa (AN) cases. Method Fifty-one adolescent-onset AN cases recruited after community screening and 51 matched comparison cases were interviewed 10 years after reported AN onset, at mean age 24 years, regarding children, miscarriages, and fertility problems. They completed anonymously the Finkelhor self-report questionnaire regarding history of CSA. Results There were few fertility problems in our AN population. There was a tendency towards more subjects in the AN group to give birth to a child (10 AN and 4 comparison mothers). The prevalence of CSA was equal between groups. For example, 6% in each group had experienced CSA before the age of 10 years, and 14% of the AN and 12% of the comparison cases reported CSA. Discussion Infertility and history of CSA may not be overrepresented in a population-based AN sample at long-term follow-up. © 2005 by Wiley Periodicals, Inc. [ABSTRACT FROM AUTHOR]

Deals with a study which evaluated bone mineral density and body composition 11 years after the onset of anorexia nervosa. Methods; Results; Discussion.

Receptors of the 5-HT2C subtype are assumed to be involved in the influence of serotonin on food intake. A polymorphism in the coding region of the gene for this receptor, resulting in a cysteine to serine substitution, has been reported. Fifty-seven somatically healthy teenage girls displaying weight loss and 91 normal-weight girls of the same age, all recruited by means of a population-based screening study, were compared with respect to this polymorphism. Subjects in the weight loss group displayed a higher frequency of the serine allele than those in the comparison group (23.7% vs. 7.7%, p = .0001). Seventy-two percent of the weight loss girls fulfilled the diagnostic criteria of anorexia nervosa, whereas 28% did not; when these two groups were separately analyzed, both differed significantly from controls with respect to serine allele frequency. The results support the notion that the studied gene may be involved in the regulation of food intake in young women. [Copyright &y& Elsevier]

This study aimed at assessing the prevalence of eating disorders (EDs) and ED symptomatology in children with obesity, and at investigating whether EDs occur more often among individuals with a comorbid attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). Seventy-six children (37 girls, 39 boys, age 5–16 years) were recruited at an outpatient obesity clinic. The adolescents completed ED instruments including The Eating Disorder Examination Questionnaire (EDE-Q) and The Eating Disorder Inventory for children (EDI-C). The parents of all participants were interviewed regarding the child's psychiatric morbidity. Diagnoses of ADHD and ASD were collected from medical records. Anthropometric data were compiled. Eight participants (11%) fulfilled the criteria for a probable ED and 16 participants (21%) had ADHD and/or ASD. Two adolescent girls had a probable ED and coexistent ADHD and ASD. No other overlaps between EDs and ADHD/ASD were observed. Loss of control (LOC) eating was present in 26 out of 40 (65%) adolescents, seven of whom had ADHD, ASD or both. LOC eating was not overrepresented among teenagers with ADHD and/or ASD. Weight and shape concerns were on a par with age-matched adolescents with EDs. EDs and ED behavior are more common among children/adolescents with obesity than in the general population. There is no substantial overlap between EDs and ADHD/ASD in adolescents with obesity.
