How do you define recovery? A qualitative study of patients with eating disorders, their parents, and clinicians.

OBJECTIVE: Recovery from an eating disorder (ED) may be defined differently by different stakeholders. We set out to understand the definition of ED recovery from the perspective of patients, their parents, and clinicians. METHOD: We recruited patients with EDs (n = 24, ages 12-23 years) representing different diagnoses (anorexia nervosa n = 17, bulimia nervosa n = 4, binge-ED n = 2, avoidant/restrictive food intake disorder n = 1), along with their parents (n = 20), dietitians (n = 11), therapists (n = 14), and primary care providers (n = 9) from three sites: Boston Children's Hospital, University of Michigan C. S. Mott Children's Hospital, and Penn State Hershey Children's Hospital. In-depth, semi-structured, qualitative interviews explored participants' definitions of recovery. Interviews were analyzed using inductive data-driven thematic analysis. Statistical analyses followed to examine the distribution within each theme by respondent type. RESULTS: Qualitative analysis resulted in the emergence of four overarching themes of ED recovery: (a) psychological well-being, (b) eating-related behaviors/attitudes, (c) physical markers, and (d) self-acceptance of body image. Endorsement of themes two and four did not significantly differ between patients, parents, and clinicians. Clinicians were significantly more likely to endorse theme one (χ2 = 9.90, df = 2, p = .007, φc = 0.356) and theme three (χ2 = 6.42, df = 2, p = .04, φc = 0.287) than patients and parents. DISCUSSION: Our study demonstrates overwhelming support for psychological markers as indicators of ED recovery by all three groups. Clinicians should remain open to additional markers of recovery such as body acceptance and eating-related behaviors/emotions that may be of critical importance to patients and their caregivers.

Further support for diagnostically meaningful ARFID symptom presentations in an adolescent medicine partial hospitalization program.

OBJECTIVE: To identify potential presentations of avoidant/restrictive food intake disorder (ARFID) in a pediatric eating disorder partial hospitalization program (PHP) based on the nature of the eating restriction leading to core symptoms of ARFID. METHOD: A retrospective chart review of 83 patients ages 8-17 admitted to a PHP and diagnosed with ARFID. Charts were independently reviewed by two coders, with high inter-rater agreement (κ = 0.77). Distinct categories were identified and groups were compared on demographics, anthropometrics, comorbid psychopathology, and core ARFID symptoms. RESULTS: We identified cases characterized by predominantly selective eating based on aversions to the sensory properties of foods, lack of interest in eating/low appetite, and fear of aversive consequences from eating. We also distinguished a subset of patients with eating restrictions consistent with both selectivity and limited interest/appetite. The four primary ARFID presentation groups differed on core ARFID criteria, symptom trajectory and illness duration, mood and medical comorbidities, age, gender, and parent-reported symptoms of psychopathology. DISCUSSION: The present findings suggest that there are diagnostically meaningful ARFID subtypes that can be differentiated based on the nature of their eating restrictions, as well as other demographic, illness history features, and psychiatric comorbidity. As treatments for youth with ARFID are developed and refined, it will be important to take into consideration not only demographic differences, but also the variability in symptoms, as this might require distinct interventions and levels of care. Additionally, differing mechanisms that maintain different types of eating restrictions might necessitate unique psychological and psychiatric interventions.

Outcomes of low-weight patients with avoidant/restrictive food intake disorder and anorexia nervosa at long-term follow-up after treatment in a partial hospitalization program for eating disorders.

OBJECTIVE: To assess long-term outcomes of patients with avoidant/restrictive food intake disorder (ARFID) treated in a partial hospitalization program (PHP) for eating disorders (ED). METHOD: A cross-sectional study comparing patients with ARFID to those with anorexia nervosa (AN) who had been discharged from a PHP for at least 12 months was performed. Percent median body mass index (%MBMI), scores on the Children's Eating Attitudes Test (ChEAT), and treatment utilization were assessed, with intake and discharge data collected via retrospective chart review. RESULTS: Of the 137 eligible patients, 62 (45.3%) consented to follow-up data collection. Patients with ARFID and AN exhibited similar increases in %MBMI from intake to discharge and reported low scores on the ChEAT by discharge. Patients with ARFID and AN maintained good weight outcomes and low ChEAT scores at follow-up. Most participants were still receiving outpatient treatment from a variety of providers, although fewer with ARFID than AN continued to receive services from our multidisciplinary ED clinic. DISCUSSION: Patients with ARFID and AN exhibit similar improvements in %MBMI when treated in the same PHP and appear to maintain treatment gains at long-term follow-up. Additionally, most patients continue to utilize outpatient services after being discharged from a PHP.

Avoidant/restrictive food intake disorder: a new eating disorder diagnosis in the diagnostic and statistical manual 5.

PURPOSE OF REVIEW: Avoidant/restrictive food intake disorder (ARFID) is a new eating disorder diagnosis in the 5th edition of the diagnostic and statistical manual (DSM-5), published in 2013. The purpose of this review is to describe the creation of ARFID as a diagnostic category, and to explain the DSM-5 diagnostic criteria; to demonstrate what is known thus far about the prevalence of ARFID and characteristics of patients with this disorder; to provide guidance to the pediatrician and other providers on making a diagnosis of ARFID; and to discuss evolving treatment approaches. RECENT FINDINGS: Several studies have been published recently on the prevalence and characteristics of patients with ARFID. Research has just begun to focus on new assessment measures, approaches to treatment based on established therapies for other eating/psychiatric disorders, and short-term outcomes. Robust treatment studies are in development. SUMMARY: The addition of ARFID to the DSM-5 has captured a category of patients with clinically significant restrictive eating, but without weight and shape concerns, who were poorly classified in the past. Future research is needed to further elucidate the presentation, characteristics, diagnostic instruments, and effective management.

Treatment of avoidant/restrictive food intake disorder in a cohort of young patients in a partial hospitalization program for eating disorders.

OBJECTIVE: Avoidant/restrictive food intake disorder (ARFID) is a recently named condition to classify patients who present with restricted nutritional intake without body image distortion or fear of weight gain. We sought to compare treatment outcomes of patients with ARFID in a family-centered partial hospital program (PHP) to those with other eating disorders (ED). METHOD: A retrospective chart review of 130 patients 7-17 years of age admitted to the program from 2008 to 2012 was performed. Intake and discharge data included: length of stay; percentage median body mass index (%MBMI); and scores on the Children's Eating Attitudes Test (ChEAT) and Revised Children's Manifest Anxiety Scale (RCMAS). Between and within group effects were measured for intake and discharge data. RESULTS: Patients with ARFID spent significantly fewer weeks in program than those with anorexia nervosa (AN) and experienced a similar increase in %MBMI as patients with AN and other specified/unspecified feeding and eating disorders. All patients exhibited significant improvements in psychopathology over the course of treatment as measured by scores on the ChEAT and RCMAS. DISCUSSION: Our findings suggest that patients with ARFID can be successfully treated in the same PHP as patients with other ED, with comparable improvements in weight and psychopathology over a shorter time period. Results are limited to patients with ARFID who exhibit an acute onset of severe food restriction. Future research should incorporate measures relevant to the diagnosis of ARFID and explore how patients with different ARFID subtypes may respond to various treatments.

Motivational stage of change in young patients undergoing day treatment for eating disorders.

BACKGROUND: The objective was to determine whether motivation to change is significantly altered over the course of partial hospitalization in children and adolescents with eating disorders (EDs). METHOD: This study was a retrospective chart review of 30 sets of adolescents and their parents who completed the Motivational Stage of Change for Adolescents Recovering from an Eating Disorder (MSCARED) at both intake and discharge from partial hospitalization. The main outcome variables included change in stage of change (SOC) for patients and their parents. Secondary outcomes included correlations between SOC and other baseline variables, as well as changes in SOC and psychological test scores. RESULTS: The SOC was significantly higher at discharge than at intake in both the patients and parents, but the two groups were not in agreement at discharge. The change in the SOC was correlated with change in Children's Eating Attitudes Test scores. Assessment of decisional balance showed correlations with SOC. Age, change in weight, and psychiatric diagnoses did not correlate with initial SOC. CONCLUSION: The MSCARED may be a useful tool for monitoring young ED patients' psychological improvements with day treatment. Initial SOC is not predictive of treatment outcomes.

Association of the COVID-19 Pandemic With Adolescent and Young Adult Eating Disorder Care Volume.

Importance: The COVID-19 pandemic has affected youth mental health. Increases in site-specific eating disorder (ED) care have been documented; however, multisite studies demonstrating national trends are lacking. Objective: To compare the number of adolescent/young adult patients seeking inpatient and outpatient ED care before and after onset of the COVID-19 pandemic. Design, Setting, and Participants: Using an observational case series design, changes in volume in inpatient and outpatient ED-related care across 15 member sites (14 geographically diverse hospital-based adolescent medicine programs and 1 nonhospital-based ED program) of the US National Eating Disorder Quality Improvement Collaborative was examined. Sites reported monthly volumes of patients seeking inpatient and outpatient ED care between January 2018 and December 2021. Patient volumes pre- and postpandemic onset were compared separately for inpatient and outpatient settings. Demographic data such as race and ethnicity were not collected because this study used monthly summary data. Exposures: Onset of the COVID-19 pandemic. Main Outcomes and Measures: Monthly number of patients seeking inpatient/outpatient ED-related care. Results: Aggregate total inpatient ED admissions were 81 in January 2018 and 109 in February 2020. Aggregate total new outpatient assessments were 195 in January 2018 and 254 in February 2020. Before the COVID-19 pandemic, the relative number of pooled inpatient ED admissions were increasing over time by 0.7% per month (95% CI, 0.2%-1.3%). After onset of the pandemic, there was a significant increase in admissions over time of 7.2% per month (95% CI, 4.8%-9.7%) through April 2021, then a decrease of 3.6% per month (95% CI, -6.0% to -1.1%) through December 2021. Prepandemic, pooled data showed relative outpatient ED assessment volume was stable over time, with an immediate 39.7% decline (95% CI, -50.4% to -26.7%) in April 2020. Subsequently, new assessments increased by 8.1% (95% CI, 5.3%-11.1%) per month through April 2021, then decreased by 1.5% per month (95% CI, -3.6% to 0.7%) through December 2021. The nonhospital-based ED program did not demonstrate a significant increase in the absolute number of admissions after onset of the pandemic but did see a significant increase of 8.2 (95% CI, 6.2-10.2) additional inquiries for care per month in the first year after onset of the pandemic. Conclusions and Relevance: In this study, there was a significant COVID-19 pandemic-related increase in both inpatient and outpatient volume of patients with EDs across sites, particularly in the first year of the pandemic. Given inadequate ED care availability prior to the pandemic, the increased postpandemic demand will likely outstrip available resources. Results highlight the need to address ED workforce and program capacity issues as well as improve ED prevention strategies.

Metabolic assessment of menstruating and nonmenstruating normal weight adolescents.

OBJECTIVE: Resumption of menses (ROM) is a key indicator of recovery in AN, but patients may remain amenorrheic despite weight restoration. The objective of this study is to better understand the mechanism of amenorrhea in patients with eating disorders. METHOD: A retrospective chart review was conducted of 382 normal weight adolescents with a history of anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified, who had been referred for indirect calorimetry tests. Resting energy expenditure (REE) was compared between amenorrheic (n = 60) and regularly menstruating females (n = 121). RESULTS: Participants with amenorrhea had a mean REE of 1,103 kcal/24 h (79% predicted), whereas participants who were menstruating regularly had a mean REE of 1,217 kcal/24 h (85% predicted; p = 0.001). The amenorrheic group was found to be at a lower mean body weight (53.7 +/- 5.6 kg vs. 57.5 +/- 7.4 kg; p < or = 0.001), at a lower percent ideal body weight (98.5 +/- 8.3% vs. 102.8 +/- 10.2%; p = 0.005), and at a lower BMI (20.5 +/- 1.7 vs. 21.5 +/- 2.2; p = 0.002). DISCUSSION: This study highlights that amenorrheic participants with a history of eating disorders who are at normal body weight are hypometabolic, suggesting an adaptive response to dietary restriction.

Assessment of Parental Knowledge and Understanding of Eating Disorders.

Recommended treatment of adolescent eating disorders includes active parental involvement. The purpose of this study was to assess baseline parental knowledge and understanding of eating disorders and how it is affected by participation in treatment. A cross-sectional and prospective cohort study comparing the parents of children ages 8 to 18 years seeking initial evaluation for an eating disorder at an adolescent medicine clinic (ED) to those attending appointments at a general pediatrics clinic (GP) was performed utilizing a 20-item questionnaire. There was no difference in mean scores at baseline, however after 2 months, the mean score of the ED group was significantly higher, while that of the GP group was not. The change in mean score from the first to second survey was significantly greater for the ED group than the GP group. Increased knowledge may improve self-efficacy, which plays a critical role in parents' ability to adopt eating disorder treatments.

History of Overweight/Obesity as Predictor of Care Received at 1-year Follow-Up in Adolescents With Anorexia Nervosa or Atypical Anorexia Nervosa.

PURPOSE: Previous research has indicated that patients with anorexia nervosa (AN) or atypical AN with premorbid history of overweight/obesity have greater weight loss and longer illness duration than patients with no such history. However, little is known about the association of premorbid overweight/obesity and receiving inpatient medical care during treatment for an eating disorder. METHODS: Using logistic regression, we sought to determine if history of overweight/obesity was associated with receiving inpatient medical care in a sample of 522 patients (mean age 15.5 years, 88% female) with AN/atypical AN. RESULTS: Binary results demonstrated greater percent weight loss (27.4% vs. 16.2%) and higher percent median body mass index (%mBMI, 99.8% vs. 85.2%) at presentation in those with a history of overweight/obesity (p < .001) but no difference in duration of illness (p = .09). In models adjusted for demographics and percent weight loss, history of overweight/obesity was associated with lower odds of receiving inpatient medical care (odds ratio .60 [95% confidence interval: .45-.80]) at 1-year follow-up. However, these associations were no longer significant after adjusting for %mBMI. Mediation results suggest that %mBMI fully mediates the relationship between history of overweight/obesity and inpatient medical care, in that those with a history of overweight/obesity are less likely to receive care due to presenting at a higher weight. CONCLUSIONS: Our findings suggest that, despite greater degree of weight loss and no difference in duration of illness, participants with a history of overweight/obesity are less likely to receive inpatient medical care.

Hormonal contraception in adolescents: special considerations.

With the rates of unintended pregnancies in teenagers remaining high, it is crucial to present adolescents with all of the contraceptive options available to them. While barrier methods, for example, male condoms, are easily accessible and do not have adverse effects, their use must be consistent and correct with each act of intercourse. Hormonal contraception affords much better efficacy in preventing pregnancy when used with full compliance. Oral contraceptives are a popular method of contraception among adolescents and offer many non-contraceptive benefits along with the prevention of pregnancy. They have very few significant adverse effects, which are outweighed by the significant morbidity associated with teenage pregnancies, and can be used by most adolescent females. However, their minor bothersome effects do contribute to the high discontinuation rates seen. In addition, many girls find it difficult to remember to take a pill every day, leading to higher failure rates in teenagers than in adult women. The advent of long-acting, progestogen (progestin)-only methods, such as injectables and implantables, has been generally accepted by adolescents and these methods have proven to be more efficacious by avoiding the need for daily compliance. However, progestogen-only methods cause irregular bleeding and amenorrhea, which is not acceptable to many teenagers. In addition, the most widely used implant was taken off the market a few years ago and newer forms are not yet widely accessible. Other novel methods are currently available, including the transdermal patch and the vaginal ring. Both are combinations of estrogen and progestogen and have similar efficacy and adverse effect profiles to oral contraceptives. Their use may be associated with greater compliance by adolescents because they also do not require adherence to a daily regimen. However, there may be some drawbacks with these newer methods, for example, visibility of the patch and difficulty with insertion of the vaginal ring. When regular contraceptive modalities fail, emergency contraception is available. Choices include combination oral contraceptives, progestogen-only pills, mifepristone, or placement of a copper-releasing intrauterine device. These methods can be very useful for preventing pregnancy in adolescents as long as adolescents are aware of their existence and have easy access to them.

Supersize teens: the metabolic syndrome.

With obesity and type 2 diabetes on the rise in children and adolescents, there has been recent interest in the study of the metabolic (insulin resistance) syndrome in this population. Characteristics of the syndrome include impaired glucose tolerance, hypertension, dyslipidemia, and abdominal obesity. These features are known to cluster and convey increased cardiovascular risk over time. Screening of children and adolescents is important to the goal of prevention, and therapeutic lifestyle modification is the primary treatment modality. When this fails, pharmacotherapy aimed at the individual risk factors may be indicated.

The impact of social support on the risk of eating disorders in women exposed to intimate partner violence.

BACKGROUND: Eating disorders (EDs) are often found among women exposed to intimate partner violence (IPV). The role of social support (SS) as a protective factor against ED among IPV-exposed women is not firmly established. OBJECTIVE: The objective of this study is to determine the distribution of risk of EDs among women exposed to IPV and to examine the impact of SS on risk of ED among IPV-exposed women. METHODS: Women (aged 18-64 years) exposed to IPV during their lifetimes (defined by the Humiliation-Afraid-Rape-Kick instrument) were recruited from primary care and domestic violence service agencies and surveyed on demographics, mood/anxiety disorders, psychosocial/community factors, and strategies used in response to IPV. The Eating Disorder Screen for Primary Care assessed the risk of ED. A modified Medical Outcomes Study Social Support Survey assessed overall functional support (scale range: 0-32; categorized into quartiles). Ordinal logistic regression examined the risk of ED based on SS, controlling for prespecified demographics (age, race/ethnicity, marital status, near-poverty level), and health-related factors significant in bivariate analyses (risky alcohol use). RESULTS: Among 302 women with lifetime IPV, 41 (14%) were at high risk, 127 (42%) were at moderate risk, and 134 (44%) were at low risk of an ED. In bivariate analyses, high risk of an ED was significantly more frequent among women with a low SS score (<19, 24%) versus a high SS score (≥30, 12%) (P=0.03). High risk of an ED was significantly associated with risky alcohol use (18%) versus non-risky alcohol use (13%; P=0.008). In multivariable analysis, a 5-unit increase in overall SS was significantly associated with decreased odds of ED risk (P=0.007). CONCLUSION: Among IPV-exposed women, low SS is associated with an increased risk of ED. SS may protect against ED by reducing anxiety and promoting positive actions, but further study is needed to confirm this.

Update on the medical management of eating disorders in adolescents.

The medical practitioner has an important role to play in the management of adolescents with eating disorders, usually as part of a multidisciplinary team. This article reviews the role of the medical practitioner in the diagnosis and treatment of eating disorders, updating the reader on the changing epidemiology of eating disorders, revised diagnostic criteria, newer methods of assessing degree of malnutrition, more aggressive approaches to refeeding, and current approaches to managing low bone mass.

Hypophosphatemia during nutritional rehabilitation in anorexia nervosa: implications for refeeding and monitoring.

PURPOSE: To determine the incidence of hypophosphatemia in adolescents with anorexia nervosa (AN) hospitalized for nutritional rehabilitation and to examine factors predisposing to its development. METHODS: A retrospective chart review of 69 patients (66 female, 3 male) with AN consecutively admitted to an inpatient adolescent medical unit between July 1, 1998 and June 30, 2000. Mean age was 15.5 +/- 2.4 (range 8 to 22) years and mean % ideal body weight (IBW) was 72.7 +/- 7%. Serum phosphorus was measured daily for 1 week and then biweekly to weekly. Patients were started on 1200-1400 kcal/day and calories were increased by 200 kcal every 24-48 hours. RESULTS: Four (5.8%) patients developed moderate hypophosphatemia (<2.5 and > or = 1.0 mg/dl) and 15 (21.7%) had mild hypophosphatemia (<3.0 and > or = 2.5 mg/dl). Patients who developed moderate hypophosphatemia were significantly more malnourished than those who did not (p = 0.02). Phosphorus nadirs were directly proportional to % IBW (r = 0.3, p = 0.01). Over three-quarters of the patients (81%) reached their phosphorus nadir within the first week of hospitalization. The patient with the lowest phosphorus level experienced short runs of ventricular tachycardia. No other severe complications were seen. Overall, 19 (27.5%) patients required phosphorus supplementation. CONCLUSIONS: Phosphorus drops to its nadir during the first week of refeeding. We recommend daily monitoring of serum phosphorus with supplementation as needed during the first week of hospitalization, especially in those who are severely malnourished.

Prevalence and characteristics of avoidant/restrictive food intake disorder in a cohort of young patients in day treatment for eating disorders.

BACKGROUND: Avoidant/Restrictive Food Intake Disorder (ARFID) is a "new" diagnosis in the recently published DSM-5, but there is very little literature on patients with ARFID. Our objectives were to determine the prevalence of ARFID in children and adolescents undergoing day treatment for an eating disorder, and to compare ARFID patients to other eating disorder patients in the same cohort. METHODS: A retrospective chart review of 7-17 year olds admitted to a day program for younger patients with eating disorders between 2008 and 2012 was performed. Patients with ARFID were compared to those with anorexia nervosa, bulimia nervosa, and other specified feeding or eating disorder/unspecified feeding or eating disorder with respect to demographics, anthropometrics, clinical symptoms, and psychometric testing, using Chi-square, ANOVA, and post-hoc analysis. RESULTS: 39/173 (22.5%) patients met ARFID criteria. The ARFID group was younger than the non-ARFID group and had a greater proportion of males. Similar degrees of weight loss and malnutrition were found between groups. Patients with ARFID reported greater fears of vomiting and/or choking and food texture issues than those with other eating disorders, as well as greater dependency on nutritional supplements at intake. Children's Eating Attitudes Test scores were lower for children with than without ARFID. A higher comorbidity of anxiety disorders, pervasive developmental disorder, and learning disorders, and a lower comorbidity of depression, were found in those with ARFID. CONCLUSIONS: This study demonstrates that there are significant demographic and clinical characteristics that differentiate children with ARFID from those with other eating disorders in a day treatment program, and helps substantiate the recognition of ARFID as a distinct eating disorder diagnosis in the DSM-5.

Characteristics of avoidant/restrictive food intake disorder in children and adolescents: a "new disorder" in DSM-5.

PURPOSE: To evaluate the DSM-5 diagnosis of Avoidant/Restrictive Food Intake Disorder (ARFID) in children and adolescents with poor eating not associated with body image concerns. METHODS: A retrospective case-control study of 8-18-year-olds, using a diagnostic algorithm, compared all cases with ARFID presenting to seven adolescent-medicine eating disorder programs in 2010 to a randomly selected sample with anorexia nervosa (AN) and bulimia nervosa (BN). Demographic and clinical information were recorded. RESULTS: Of 712 individuals studied, 98 (13.8%) met ARFID criteria. Patients with ARFID were younger than those with AN (n = 98) or BN (n = 66), (12.9 vs. 15.6 vs. 16.5 years), had longer durations of illness (33.3 vs. 14.5 vs. 23.5 months), were more likely to be male (29% vs. 15% vs. 6%), and had a percent median body weight intermediate between those with AN or BN (86.5 vs. 81.0 and 107.5). Patients with ARFID included those with selective (picky) eating since early childhood (28.7%); generalized anxiety (21.4%); gastrointestinal symptoms (19.4%); a history of vomiting/choking (13.2%); and food allergies (4.1%). Patients with ARFID were more likely to have a comorbid medical condition (55% vs. 10% vs. 11%) or anxiety disorder (58% vs. 35% vs. 33%) and were less likely to have a mood disorder (19% vs. 31% vs. 58%). CONCLUSIONS: Patients with ARFID were demographically and clinically distinct from those with AN or BN. They were significantly underweight with a longer duration of illness and had a greater likelihood of comorbid medical and/or psychiatric symptoms.

Impulsivity, anxiety, and alcohol misuse in bipolar disorder comorbid with eating disorders.

BACKGROUND: Eating disorders (ED) are noted to occur with bipolar disorder (BD), but relationships between additional comorbidities, clinical correlates, and personality factors common to both remain largely unknown. METHODS: Using data from the Prechter Longitudinal Study of Bipolar Disorder, we measured the prevalence and demographic factors of comorbid ED with BD, presence of additional comorbidity of anxiety and substance use disorders, psychosis, suicide attempts, mixed symptoms, childhood abuse, impact of NEO-Personality Inventory (NEO-PI) personality factors, and mood outcome in 354 patients with BD. We analyzed the prevalence of ED using both broad and narrow criteria. RESULTS AND DISCUSSION: ED was more common in the Prechter BD sample than the general population, with the majority of those with ED being female. Anxiety disorders, alcohol abuse/dependence, and NEO-PI N5 impulsiveness were independently associated with ED in a multivariable linear regression analysis. BD age at onset was earlier in the ED group than that in the non-ED group and was earlier than the average onset of ED. Anxiety occurred before ED and alcohol use disorders after both BD and ED. Childhood trauma was associated with ED. Impulsivity and anxiety associated with BD may fuel ED and put patients at risk for other impulsivity-related disorders such as alcohol use disorders. ED was associated with more severe and variable moods and more frequent depression. Patients with BD should be regularly screened for ED, anxiety disorders, and alcohol use disorders, and comorbidity should be promptly addressed.

Distribution of eating disorders in children and adolescents using the proposed DSM-5 criteria for feeding and eating disorders.

PURPOSE: To determine the distribution of eating disorders (ED) in children and adolescents comparing the fourth edition of the Diagnostic and Statistical Manual (DSM) to the proposed fifth edition DSM criteria. METHODS: A total of 215 consecutive patients (15.4 ± 3.3 years) presenting for initial ED evaluation to adolescent medicine physicians from six institutions were assigned ED diagnoses using current DSM-IV criteria as well as proposed DSM-5 criteria. RESULTS: Diagnoses of anorexia nervosa and bulimia nervosa increased using the proposed DSM-5 criteria (from 30.0% to 40.0% and from 7.3% to 11.8%, p < .001). Approximately 14% of patients received the presumptive DSM-5 diagnosis of avoidant/restrictive food intake disorder. Cases of ED not otherwise specified decreased from 62.3% to 32.6% (p < .001). CONCLUSIONS: Proposed DSM-5 criteria substantially decreased the frequency of ED not otherwise specified diagnoses and increased the number of cases of anorexia nervosa and bulimia nervosa in a population of young patients presenting for ED treatment. Avoidant/restrictive food intake disorder appears to be a significant diagnosis.

Effect of weight loss on menstrual function in adolescents with polycystic ovary syndrome.

STUDY OBJECTIVE: To compare the effects of a hypocaloric low-fat diet with those of a very low carbohydrate diet on body mass index (BMI), waist circumference (WC), and menstrual function in overweight adolescent females with polycystic ovary syndrome (PCOS). DESIGN: Randomized pilot trial of two diets in a prospective, 12-week study. SETTING: A hospital-based, academic adolescent medicine division. PARTICIPANTS: 24 females, age 12-22 years (mean 15.8 ± 2.2), with PCOS and a BMI above the 85(th) percentile for age (mean 35.7 ± 6.0 kg/m(2)). INTERVENTIONS: Nutrition counseling was given biweekly, and dietary compliance, menstrual history, and weight were recorded. WC was measured at the beginning and end of the study. MAIN OUTCOME MEASURES: Changes in weight, BMI, WC, and improvement in menstrual function over the course of the study period. RESULTS: 16 participants completed the study. 12 completers menstruated during the study period, 8 with regularity. The number of periods over 3 months increased from 0.6 ± 0.6 pre-treatment to 1.6 ± 1.3 post-treatment (P = 0.003). Overall, weight loss averaged 6.5% (P < 0.0001) and the WC decreased by an average of 5.7 ± 7.7 cm (P = 0.01). Those who lost weight were 3.4 times more likely to have improved menstrual function (P = 0.001). There were no statistically significant differences between the two groups. CONCLUSIONS: Weight loss is feasible in adolescents with PCOS and results in significant improvements in BMI, WC, and menstrual function. Weight management may be preferable as first-line treatment in adolescents, because it targets both the menstrual dysfunction and risk factors for long-term morbidity associated with PCOS.
