Anorexia nervosa in males: excess mortality and psychiatric co-morbidity in 609 Swedish in-patients

Overall and cause-specific mortality in anorexia nervosa; impact of psychiatric comorbidity and sex in a 40-year follow-up study

OBJECTIVE

This study investigates the overall and cause-specific mortality in males and females with anorexia nervosa (AN) from 1977 to 2018, focusing on the impact of psychiatric comorbidity on mortality risk, a less explored aspect despite a high prevalence in patients with AN.

METHOD

We conducted a nationwide population-based cohort study in Denmark including all patients with AN (n = 14,774) with a median follow-up time of 9.1 years and a 1:10 age- and sex-matched general population comparison cohort. Using Cox proportional hazard model, we calculated adjusted hazard ratios (aHR) for death stratified by psychiatric comorbidity, sex, and age at AN onset and evaluated the causes of death using Fine and Gray sub-distribution hazard ratios (SHR).

RESULTS

In patients with AN, the weighted average aHR for all-cause mortality was 4.5 [95% CI 4.1-4.9] with up to 40 years follow-up. Psychiatric comorbidity was present in 47% of patients with AN at index date, which was associated with a 1.9-fold increase in 10-year mortality compared with patients without comorbidity and a notably four-fold increase, when diagnosed at age 6-25 years. The mortality risk was similar according to sex. 13.9% of all deaths in patients with AN were due to suicide (SHR 10.7 [8.1-14.2]). The risk of dying of natural causes was increased with a SHR of 3.8 [95% CI 3.4-4.2].

DISCUSSION

The increased mortality risk in both males and females with AN and psychiatric comorbidity, particularly when diagnosed at young age, underscores the need for comprehensive treatment addressing both AN and coexisting psychiatric conditions.

PUBLIC SIGNIFICANCE

The mortality in patients with anorexia nervosa (AN) is high and we show in our study that the mortality is doubled in the presence of psychiatric comorbidity particularly the first 10 years after diagnosis seen in both sexes and with suicide as a major cause of death. These findings stress the importance of detection and treatment of psychiatric comorbidities alongside the eating disorder to prevent fatal outcome.

Inpatient admissions and mortality of anorexia nervosa patients according to their preceding psychiatric and somatic diagnoses

OBJECTIVE

Anorexia nervosa (AN) is associated with increased risk of mortality, but little is known about the risk of inpatient admissions and mortality outcomes in individuals with diagnoses of both AN and other psychiatric and somatic conditions. We aimed to investigate the inpatient admissions and mortality among people with AN and other diagnosed conditions using Danish national registers.

METHOD

This retrospective cohort study included individuals diagnosed with AN in Denmark, born 1977-2010. We identified other mental and somatic conditions in this population. We used Cox proportional hazards regression to estimate the risk of inpatient admission and mortality, focusing on (i) the number of other diagnosed conditions, and (ii) specific combinations of conditions diagnosed prior to the AN diagnosis. Categories of inpatient admissions considered were due to: (i) AN, (ii) any psychiatric disorder, and (iii) any somatic disorder. Additionally, competing risks survival analysis was used to calculate the cumulative incidence of inpatient admission and all-cause mortality over the follow-up period.

RESULTS

The study population included 11,489 individuals. The most common conditions individuals had prior to their AN diagnosis were other eating disorders (34.5%) and anxiety disorders (32.7%). During the follow-up, 3184 (27.7%), 4604 (40.1%), and 6636 (57.8%) individuals were admitted for AN, any psychiatric disorder, and any somatic disorder, respectively; and in total 106 (0.9%) died. The risk of all outcomes was highest among those who had received a higher number of other diagnoses. For most combinations, the risks of admission and mortality were increased.

DISCUSSION

Our study presents the prevalence of other conditions in patients with AN in Denmark and elucidates their association with higher rates of inpatient admission and mortality. Our findings highlight the need for comprehensive, multidisciplinary care of patients with AN considering the spectrum of other diagnosed conditions to improve health outcomes.

Dissecting the biology of feeding and eating disorders

Feeding and eating disorders (FEDs) are heterogenous and characterized by varying patterns of dysregulated eating and weight. Genome-wide association studies (GWASs) are clarifying their underlying biology and their genetic relationship to other psychiatric and metabolic/anthropometric traits. Genetic research on anorexia nervosa (AN) has identified eight significant loci and uncovered genetic correlations implicating both psychiatric and metabolic/anthropometric risk factors. Careful explication of these metabolic contributors may be key to developing effective and enduring treatments for devastating, life-altering, and frequently lethal illnesses. We discuss clinical phenomenology, genomics, phenomics, intestinal microbiota, and functional genomics and propose a path that translates variants to genes, genes to pathways, and pathways to metabolic outcomes to advance the science and eventually treatment of FEDs.

New understandings meet old treatments: putting a contemporary face on established protocols

In the twenty years since the publication of the most widely used treatment manuals describing evidence-based therapies for eating disorders, there have been some substantial advances in the field. New methods of delivering treatments have been trialled and our perception of mental health has advanced; significant cultural changes have led to shifts in our societal landscape; and new technologies have allowed for more in-depth research to be conducted. As a result, our understanding of eating disorders and their treatment has broadened considerably. However, these new insights have not necessarily been translated into improved clinical practice. This paper highlights the changes we consider to have had the greatest impact on our work as experienced clinical psychologists in the field and suggests a list of new learnings that might be incorporated into clinical practice and research design.

Anorexia Nervosa With Comorbid Severe Depression: A Systematic Scoping Review of Brain Stimulation Treatments

ABSTRACT

Major depressive disorder (MDD) is highly prevalent in individuals with anorexia nervosa (AN) and is a predictor of greater clinical severity. However, there is a limited amount of evidence supporting the use of psychotropic medications for its management. A systematic scoping review was conducted to assess the current literature on brain stimulation treatments for AN with comorbid MDD, with a specific focus on MDD treatment response and weight restoration. This review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, and the PubMed, PsycInfo, and MEDLINE databases were searched until July 2022 using specific key words related to AN and brain stimulation treatments. A total of 373 citations were identified, and 49 treatment studies that met the inclusion criteria were included in the review. The initial evidence suggests that electroconvulsive therapy, repetitive transcranial magnetic stimulation, and deep-brain stimulation may be effective in managing comorbid MDD in AN. Emerging evidence suggests that transcranial direct current stimulation may have a positive effect on body mass index in individuals with severe to extreme AN. However, there is a need for the development of better measurement techniques for assessing the severity of depression in the context of AN. Controlled trials that are adequately designed to account for these limitations are highly warranted for deep-brain stimulation, electroconvulsive therapy, and repetitive transcranial magnetic stimulation and hold promise for providing clinically meaningful results.

Secular trends in the incidence of eating disorders in China from 1990 to 2017: a joinpoint and age-period-cohort analysis

BACKGROUND

Eating disorders (ED) have increasingly become a global topic of concern for public health. A better understanding of ED incidence is a basic requirement for improving its management. However, the temporal trend of ED incidence in China is still unknown.

METHODS

The incidence rates of ED from 1990 to 2017 were collected from the Global Burden of Disease Study 2017 database according to the following: subtype, i.e. anorexia nervosa (AN) and bulimia nervosa (BN); sex; and age group. The average annual percent changes and relative risks were calculated using joinpoint regression and the age-period-cohort model, respectively.

RESULTS

From 1990 to 2017, age-standardized incidence rates of ED continued to increase in males and females, and this variation trend was observed in AN and BN. Joinpoint regression analysis showed that the incidence rates increased in all age groups. Adolescents had the highest risk of developing ED, followed by young adults. Age effects were the most influential risk factor for ED incidence. Period effects showed that the risk of developing ED continuously increased with increasing time periods in BN, but not in ED and AN. Concerning the cohort effects, people born after the 1990s presented a higher risk of ED, though they presented a lower risk of BN as compared to the whole cohort.

CONCLUSIONS

ED incidence rates continue to increase in China, particularly among adolescents and young adults. Further etiological studies are needed to explain these increases and to facilitate the early identification of high-risk individuals.

Does receiving an eating disorder diagnosis increase the risk of a subsequent alcohol use disorder? A Danish nationwide register-based cohort study

BACKGROUND AND AIM

No large-scale, longitudinal clinical study has examined whether patients with different types of eating disorders (ED) have an increased risk of a subsequent alcohol use disorder (AUD). This study aimed to assess the ongoing risk of receiving a diagnosis of AUD following a first-time diagnosis of anorexia nervosa (AN), bulimia nervosa (BN), or unspecified ED (USED).

DESIGN

Retrospective cohort study.

SETTING

Danish nationwide registries, January 1994 to December 2018.

PARTICIPANTS

A total of 20 759 ED patients and 83 036 controls were followed from the date of first ED diagnosis (index date) until the date of first AUD diagnosis, death, emigration, or the end of the study. Controls were selected in a 1:4 ratio and matched on month and year of birth, gender and ethnicity.

MEASUREMENTS

We obtained data on ED (AN, BN, USED; exposure) and AUD (abuse/dependence; outcome) diagnoses as well as sociodemographics and other psychiatric diagnoses. Time to AUD was generated from the index date. Risk of AUD after the index date was assessed among those without a prior AUD diagnosis while adjusting for sociodemographics and prior psychiatric diagnoses.

FINDINGS

Compared with controls, an increased relative risk of AUD after the index date was observed in AN patients throughout the study lasting 15 + years (adjusted hazard ratios [HRs] ranging from 2.49 [99% CI = 1.46, 4.25] to 6.83 [2.84, 16.41]), in BN patients during the first year of follow-up and from 2 years onward (2.72 [1.66, 4.44] to 17.44 [6.01, 50.63]), and in USED patients during the first year and 2-15 years of follow-up (2.52 [1.54, 4.14] to 14.17 [5.86, 34.27]). In all three groups, estimates were highest during the first year, particularly among BN patients.

CONCLUSIONS

Patients with anorexia nervosa, bulimia nervosa, or unspecified eating disorders appear to have an increased ongoing risk of receiving a diagnosis of alcohol use disorder following their first eating disorder diagnosis compared with controls.

The Impact of Alcohol and Other Substance Use Disorders on Mortality in Patients With Eating Disorders: A Nationwide Register-Based Retrospective Cohort Study

OBJECTIVE

Research is lacking on the contribution of different types of substance use disorders (SUDs) to excess mortality across the full spectrum of eating disorders. The authors assessed the association of alcohol use disorders and other SUDs with mortality in anorexia nervosa, bulimia nervosa, and unspecified eating disorder compared with matched control subjects.

METHODS

A retrospective cohort study was conducted using Danish nationwide registers. The study included 20,759 patients with eating disorders and 83,036 matched control subjects. Hazard ratios were calculated to compare all-cause mortality risk between eating disorder patients and control subjects both with and without a lifetime SUD diagnosis (abuse or dependence of alcohol, cannabis, or hard drugs).

RESULTS

For patients with each type of eating disorder, a higher risk of all-cause mortality was observed relative to control subjects without SUDs among those who abused alcohol and/or cannabis (adjusted hazard ratios for the anorexia nervosa, bulimia nervosa, and unspecified eating disorder patients, respectively, were 11.28 [95% CI=7.01, 18.16], 5.86 [95% CI=3.37, 10.1], and 10.86 [95% CI=6.74, 17.50]), or hard drugs alone or in combination with alcohol and/or cannabis (adjusted hazard ratios, respectively, were 22.34 [95% CI=15.13, 33.00], 11.43 [95% CI=7.14, 18.28], and 15.53 [95% CI=10.15, 23.78]), than in those without SUDs (adjusted hazard ratios, respectively, were 3.21 [95% CI=2.43, 4.23], 1.24 [95% CI=0.88, 1.77], and 4.75 [95% CI=3.57, 6.31]). Control subjects with SUDs also exhibited an elevated risk of all-cause mortality relative to control subjects without SUDs, although to a much lesser extent than eating disorder patients with SUDs.

CONCLUSIONS

SUDs have an additive effect on excess mortality in patients with eating disorders. The prevention and treatment of SUDs in this patient group is thus imperative to reduce mortality.

SUDs have an additive effect on excess mortality in patients with eating disorders. The prevention and treatment of SUDs in this patient group is thus imperative to reduce mortality.

Excess mortality associated with eating disorders: population-based cohort study

BACKGROUND

Individuals with eating disorders have a high mortality risk. Few population-based studies have estimated this risk in eating disorders other than anorexia nervosa.

AIMS

To investigate all-cause mortality in a population-based cohort of individuals who received hospital-based care for an eating disorder (anorexia nervosa, bulimia nervosa or eating disorder not otherwise specified) in Ontario, Canada.

METHOD

We conducted a retrospective cohort study of 19 041 individuals with an eating disorder from 1 January 1990 to 31 December 2013 using administrative healthcare data. The outcome of interest was death. Excess mortality was assessed using standardised mortality ratios (SMRs) and potential years of life lost (PYLL). Cox proportional hazards regression models were used to examine sociodemographic and medical comorbidities associated with greater mortality risk.

RESULTS

The cohort had 17 108 females (89.9%) and 1933 males (10.1%). The all-cause mortality for the entire cohort was five times higher than expected compared with the Ontario population (SMR = 5.06; 95% CI 4.82-5.30). SMRs were higher for males (SMR = 7.24; 95% CI 6.58-7.96) relative to females (SMR = 4.59; 95% CI 4.34-4.85) overall, and in all age groups in the cohort. For both genders, the cohort PYLL was more than six times higher than the expected PYLL in the Ontario population.

CONCLUSIONS

Patients with eating disorders diagnosed in hospital settings experience five to seven times higher mortality rates compared with the overall population. There is an urgent need to understand the mortality risk factors to improve health outcomes among individuals with eating disorders.

What can we learn about eating disorder mortality from eating disorder diagnoses at initial assessment? A Danish nationwide register follow-up study using record linkage, encompassing 45 years (1970-2014)

Increased risk for premature mortality is well established for women and girls diagnosed with anorexia nervosa (AN), but less is known for other types of eating disorder (ED), and especially the mortality outcome for boys and men is under-studied. In this registry-based observational epidemiological study, we included all people appearing in the Danish Psychiatric Central Research Register with an eating disorder (ED) diagnosis in the time period from Jan 1,1970 to Dec 31, 2014 (N: 22,633). For each patient four controls without ED were selected, matched for age, sex and place of residence (N: 90486). In all 802 people with ED died over 255762.6 person-years of observation. Standardized mortality ratio (SMR) for all-cause mortality and suicide mortality was significantly increased for all ED-diagnoses in women. The SMRs for men were similar, but only reached significance for the diagnoses AN and unspecified ED. Mortality by natural causes and accidents was significantly increased in most ED-diagnoses in women. The unequal female-to-male ratio in this, and most other studies of ED-patients, suggests that boys and men with ED have unmet needs.

Gastrointestinal symptoms from an epidemiological perspective

Four manuscripts on gastro-intestinal problems or disorders of gut-brain interaction are discussed from an epidemiological perspective. A literature review with strict inclusion criteria pointed out the dearth of evidence-based knowledge on gastrointestinal symptoms following treatment for anorexia nervosa. An epidemiological follow-up study showing the relevance of childhood abdominal pain for fasting to control weight in adolescence is used to emphasize the need to refine our approach to risk factor research in eating disorders. Two additional studies highlight the high prevalence of gastro-intestinal problems in eating disorders underscoring a need for improved consideration of these symptoms in clinical practice and eating disorder research.

Mortality in males as compared to females treated for an eating disorder: a large prospective controlled study

PURPOSE

To report on the mortality of DSM-IV eating disorders and predictors of premature death in males compared to females after inpatient treatment.

METHODS

Crude mortality rate (CMR) and standardized mortality ratio (SMR) were computed for a large sample of males aged at treatment 16-61 years [N = 66 anorexia nervosa (AN), 52 bulimia nervosa (BN), 70 eating disorder not otherwise specified (ED-NOS)] and females aged 14-65 years (N = 2066 AN, 1880 BN, 1350 ED-NOS). In addition, a survival analysis and Cox regression analyses for identifying predictors of death were computed.

RESULTS

CMRs for males and females, respectively, were 15% and 5% in AN, 8% and 3% in BN, and 4% and 3% in ED-NOS. Compared to the general population, mortality was elevated in males with AN (SMR = 4.93) and in all female diagnostic groups (AN, BN, ED-NOS). No significant sex differences for SMR emerged in any diagnostic group. Compared to females with AN or BN, males with AN or BN showed a shorter survival time after onset (survival analysis). Being male, and having AN, increased the risk of premature death.

CONCLUSION

Mortality in inpatients with eating disorder is high, especially in AN. Males appear to have about the same outcome in terms of mortality as females with AN, BN, and ED-NOS. However, long-term survival was shorter in males with AN or BN compared to females. The need for intensive treatment in both males and females with an eating disorder remains an important issue.

LEVEL OF EVIDENCE

Level III, case-control analytic study.

Five-year mortality of severely malnourished patients with chronic anorexia nervosa admitted to a medical unit

OBJECTIVE

Anorexia nervosa (AN) is associated with one of the highest mortality rates of any psychiatric disorder but limited mortality data were reported for those with extremely severe malnutrition. This study aimed to estimate standardized mortality ratio (SMR), investigate predictive factors of mortality and causes of death among a sample of patients with AN admitted to a specialized clinical nutrition unit (CNU) because of extremely severe malnutrition.

METHODS

Between 11/27/1997 and 01/15/2014, vital status was determined for 384 patients admitted for AN at the first time in the CNU. Sociodemographic, anamnestic, and clinical data were collected. We calculated the SMR. Univariate and multivariate Cox regression analyses were performed to identify mortality predictors.

RESULTS

Crude mortality rate was 11.5%. (44 deaths) and SMR 15.9 [CI 95% (11.6-21.4)], 5.2 years post inpatient treatment. Mortality predictors at the time of hospitalization were as follows: older age, occurrence of an in-hospital suicide attempt, transfer to medical intensive care unit and the following somatic complications: frank anemia, dysnatremia, infectious and cardiac complications. Other predictors of mortality were: past or present history of discharge against medical advice, hematological comorbidities (not related to AN). A longer inpatient length of stay was a protective factor.

CONCLUSION

Very severely malnourished patients with AN hospitalized in a medical unit because of extremely severe somatic issues have a medium-term mortality rate higher than the general population and even higher than patients in tertiary specialized ED units. This study highlights predictive factors of mortality that will help clinicians in recognizing and managing patients at risk of death.

The Western diet: a blind spot of eating disorder research?-a narrative review and recommendations for treatment and research

Over the last 50 years, in parallel with the obesity epidemic, the prevalence of eating disorders has increased and presentations have changed. In this narrative review, we consider recent research exploring the implications of changing patterns of food consumption on metabolic and neurobiological pathways, a hitherto neglected area in eating disorder research. One of the major changes over this time has been the introduction of ultra-processed (NOVA-4) foods, which are gradually replacing unprocessed and minimally processed foods. This has resulted in the increased intake of various sugars and food additives worldwide, which has important metabolic consequences: triggering insulin and glucose response, stimulating appetite, and affecting multiple endocrine and neurobiological pathways, as well as the microbiome. A paradigm shift is needed in the conceptual framework by which the vulnerability to, and maintenance of, different eating disorders may be understood, by integrating recent knowledge of the individual metabolic responses to modern highly processed foods into existing psychological models. This could stimulate research and improve treatment outcomes.

Mortality in males treated for an eating disorder-A large prospective study

OBJECTIVE

To report on the long-term mortality of eating disorders in male inpatients.

METHOD

Crude mortality rates (CMR) and standardized mortality ratios (SMR) were computed for a large sample of males (147 anorexia nervosa [AN], 81 bulimia nervosa [BN], 110 eating disorder not otherwise specified [ED-NOS]; DSM-IV). In addition, a survival analysis from onset of eating disorder to death or end of observation was computed.

RESULTS

CMR was 12.9% in AN, 11.1% in BN, and 6.4% in ED-NOS. Standardized mortality was significantly elevated in males with AN (SMR = 5.91; 95% confidence interval 3.56-9.23) as well as ED-NOS (SMR = 3.40; 95% confidence interval 1.37-7.01) but not in males with BN (SMR = 1.88; 95% confidence interval 0.86-3.58). Males with AN died sooner after onset of eating disorder than males with BN or ED-NOS.

DISCUSSION

Mortality in male inpatients with eating disorder is high, especially in AN. There is need for developing more effective treatments to achieve better outcome.

Psychiatric comorbidity as a risk factor for mortality in people with anorexia nervosa

Anorexia nervosa (AN) is found associated with increased mortality. Frequent comorbidities of AN include substance use disorders (SUD), affective disorders (AD) and personality disorders (PD). We investigated the influence of these psychiatric comorbidities on all-cause mortality with demographic and socioeconomic factors considered as confounders in the observation window between January 2007 and March 2016 for 1970 people with AN, using data from the case register of the South London and Maudsley (SLaM) NHS Foundation Trust, an almost monopoly-secondary mental healthcare service provider in southeast London. We retrieved data from its Clinical Records Interactive Search (CRIS) system as data source. Mortality was ascertained through nationwide tracing by the UK Office for National Statistics (ONS) linked to CRIS database on a monthly basis. A total of 43 people with AN died during the observation period. Standardized Mortality Ratio (SMR) with England and Wales population in 2012 as standard population for our study cohort was 5.21 (95% CI 3.77, 7.02). In univariate analyses, the comorbidity of SUD or PD was found to significantly increase the relative risks of mortality (HRs = 3.10, 95% CI 1.21, 7.92; and 2.58, 95% CI 1.23, 5.40, respectively). After adjustment for demographic and socioeconomic covariates as confounders, moderately but not significantly elevated risks were identified for SUD (adjusted HR = 1.39, 95% CI 0.53, 3.65) and PD (adjusted HR = 1.58, 95% CI 0.70, 3.56). These results suggest an elevated mortality in people with AN, which might be, at least partially, explained by the existence of the comorbidities SUD or PD.

Sex Differences in Adolescent Anorexia and Bulimia Nervosa: Beyond the Signs and Symptoms

PURPOSE OF REVIEW

We review research related to sex differences in eating disorders (EDs) in adolescents. Prior work has explored clinical differences; thus, we examine literature in areas identified as playing an etiological or maintenance role in EDs including: genetics, hormones, neurocognitive inefficiencies, and reward circuitry.

RECENT FINDINGS

Sex steroids appear to a play role in the unmasking of genetic risk for development of EDs and puberty may be a heightened period of risk for females. While neurocognitive differences have been well studied in adults with ED, research with adolescents has been less conclusive. Recent work suggests that neural circuitry involved in reward and punishment may play role in development and maintenance of EDs in females. Males are underrepresented in these areas of research. Given known sex differences in healthy adolescents, it is likely there are sex differences in the putative biological etiology/maintenance of EDs. Males should be included in future research.

Personality traits associated with eating disorders and obesity in young Argentineans

PURPOSE

Few studies have been conducted on Latin American population to explore how facets of personality, eating disorders, and obesity are related. The main purpose of this study was to explore the personality traits among patients diagnosed with anorexia nervosa (n = 23), bulimia nervosa (n = 32), and obesity (n = 16), in comparison to control group (n = 82).

METHODS

A total of 153 individuals participated in the study, 125 were female (81.7%) and 28 were male (18.3%). Participants' ages ranged between 18 and 37 years (mean 24.21, SD 4.84) and they were all native Spanish speakers, living in the city of Córdoba, Argentina. Participants completed the Eating Disorder Inventory-2 and the IPIP-NEO Personality Inventory.

RESULTS

In this study, the subjects diagnosed with anorexia in comparison to control group showed high and significant scores in neuroticism and openness to experience and low scores on agreeableness, conscientiousness, and extraversion. For their part, the subjects diagnosed with bulimia, in comparison to the control group, had higher and significant scores on neuroticism, extraversion, and conscientiousness. Lastly, the patients with obesity in comparison to the control group presented high and significant scores on neuroticism and low and significant scores on agreeableness, extraversion, conscientiousness, and openness to experience.

CONCLUSIONS

The results obtained from this study support previous research devoted to the study of eating disorders and obesity. This situation favors the valid and relevant nature of the study of personality traits as factors that contribute to explaining behavior disorders associated with eating pathologies. This is a preliminary and necessary step for future research to examine the risky combination of personality traits and anorexia, bulimia, and obesity in the local context using a larger and more generalized sample.

Assessment and clinical management of bone disease in adults with eating disorders: a review

AIM

To review current medical literature regarding the causes and clinical management options for low bone mineral density (BMD) in adult patients with eating disorders.

BACKGROUND

Low bone mineral density is a common complication of eating disorders with potentially lifelong debilitating consequences. Definitive, rigorous guidelines for screening, prevention and management are lacking. This article intends to provide a review of the literature to date and current options for prevention and treatment.

METHODS

Current, peer-reviewed literature was reviewed, interpreted and summarized.

CONCLUSION

Any patient with lower than average BMD should weight restore and in premenopausal females, spontaneous menses should resume. Adequate vitamin D and calcium supplementation is important. Weight-bearing exercise should be avoided unless cautiously monitored by a treatment team in the setting of weight restoration. If a patient has a Z-score less than expected for age with a high fracture risk or likelihood of ongoing BMD loss, physiologic transdermal estrogen plus oral progesterone, bisphosphonates (alendronate or risedronate) or teriparatide could be considered. Other agents, such as denosumab and testosterone in men, have not been tested in eating-disordered populations and should only be trialed on an empiric basis if there is a high clinical concern for fractures or worsening bone mineral density. A rigorous peer-based approach to establish guidelines for evaluation and management of low bone mineral density is needed in this neglected subspecialty of eating disorders.
