Health in adulthood after severe anorexia nervosa in adolescence: a study of exposed and unexposed women. Eat Weight Disord 2021; 26:1389-1397. [PMID: 32572843 DOI: 10.1007/s40519-020-00940-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Accepted: 06/04/2020] [Indexed: 12/16/2022] Open
Abstract
OBJECTIVE To compare the global health status, frequency of somatic and psychological problems, and alcohol use in adulthood among women hospitalized in adolescence for severe anorexia nervosa (AN), with a matched control sample from the general population. METHOD Women (n = 86) who had been hospitalized for AN 9.31 ± 1.82 years previously were compared with 258 controls matched for gender, age, and socio-professional category. Data were retrieved from a French survey on health and social insurance coverage, and was mainly collected by self-report, except for the assessment of current eating disorders for those previously hospitalized for AN (assessed with the MINI). RESULTS The women who had been hospitalized for AN reported significantly poorer current health status compared to controls (OR 2.9, 95% CI 1.5-5.79). According to the MINI, 13 women previously hospitalized with severe AN still presented an eating disorder (ED). Women with past AN reported more frequent acute throat infections (OR 4.9, 95% CI 1.81-13.51), gastralgia (OR 3.6, 95% CI 1.9-6.83), gastro-oesophageal reflux (OR 5.279, 95%CI 2.11-13.22), excess blood cholesterol or triglyceride levels (OR 2.55, 95% CI 1.03-6.33), anxiety (OR 8.7, 95% CI 3.48-21.8) and depression (OR 5.02 (2.8-9.01). These differences remained significant and of the same order of magnitude in sensitivity analyses among subjects with previous AN but without current ED, except for perceived health status and excess cholesterol and triglyceride levels. DISCUSSION Women who had been hospitalized for severe AN reported more symptoms 10 years after treatment, implies psychological and somatic follow-up in the long term. LEVEL OF EVIDENCE Level III, case-control analytic study.

Abstract
Decreased mineral density is one of the major complications of anorexia nervosa. The phenomenon is even more pronounced when the disease occurs during adolescence and when the duration of amenorrhoea is long. The mechanisms underlying bone loss in anorexia are complex. Oestrogen deficiency has long been considered as the main factor, but cannot explain the phenomenon on its own. The essential role of nutrition-related factors—especially leptin and adiponectin—has been reported in recent studies. Therapeutic strategies to mitigate bone involvement in anorexia are still a matter for debate. Although resumption of menses and weight recovery appear to be essential, they are not always accompanied by a total reversal of bone loss. There are no studies in the literature demonstrating that oestrogen treatment is effective, and the best results seem to have been obtained with agents that induce bone formation—such as IGF-1—especially when associated with oestrogen. As such, bone management in anorexia remains difficult, hence, the importance of early detection and multidisciplinary follow-up.

Abstract
OBJECTIVE To provide meta-analytical evidence of bone mineral density (BMD), fractures, and osteoporosis rates in eating disorders (ED) vs. healthy controls (HCs). METHOD Three independent authors searched major electronic databases from inception till August 2015 for cross-sectional studies reporting BMD in people with ED (anorexia nervosa, (AN); bulimia nervosa, (BN); eating disorders not otherwise specified, (EDNOS)) vs. HCs. Standardized mean differences (SMDs) ±95% and confidence intervals (CIs) were calculated for BMD, and odds ratios (ORs) for osteopenia, osteoporosis, and fractures. RESULTS Overall, 57 studies were eligible, including 21 607 participants (ED = 6485, HCs = 15 122). Compared to HC, AN subjects had significantly lower BMD values at lumbar spine (SMD = -1.51, 95% CI = -1.75, -1.27, studies = 42), total hip (SMD = -1.56, 95%CI = -1.84, -1.28, studies = 23), intertrochanteric region (SMD = -1.80, 95%CI = -2.46, -1.14, studies = 7), trochanteric region (SMD = -1.05, 95%CI = -1.44, -0.66, studies = 7), and femoral neck (SMD = -0.98, 95%CI = -1.12, -0.77, studies = 20). Reduced BMD was moderated by ED illness duration and amenorrhea (P < 0.05). AN was associated with an increased likelihood of osteoporosis (OR = 12.59, 95%CI = 3.30-47.9, P < 0.001, studies = 4) and fractures (OR = 1.84, 95% CI = 1.17-2.89, I(2) = 56, studies = 6). No difference in BMD was found between BN and EDNOS vs. HC. CONCLUSION People with AN have reduced BMD, increased odds of osteoporosis and risk of fractures. Proactive monitoring and interventions are required to ameliorate bone loss in AN.

Abstract
AIM This paper considers how the three principles of evidence based practice (clinical expertise, scientific evidence, and patient preference) can be applied to the complexity of treatment for anorexia nervosa AN. METHOD A narrative review of the evidence of these three domains is presented. Clinical cases are used to illustrate how the formulation and management can be put into practice at different stages of illness. RESULTS The management of anorexia nervosa is complex. First, individuals with the illness do not regard the manifestations of the illness as a source of concern rather they are embraced and integrated into their identity. This contrasts to the reaction of other people who are terrified by the overt signs of ill health. Thus engagement into treatment is problematic. Second, the core symptom restricted eating, produces malnutrition which impacts on brain, body, and the social network. Thus a mixture of psychological and physical problems gradually accumulates over the course of the illness. This means that the treatment targets increase over time. CONCLUSION Thus treatment has to work with motivation and readiness to change and tackle the various domains of ill health.

Abstract
Anorexia nervosa (AN) is a psychiatric condition characterized by severe weight loss and secondary problems associated with malnutrition. AN predominantly develops in adolescence in the peripubertal period. Without early effective treatment, the course is protracted with physical, psychological and social morbidity and high mortality. Despite these effects, patients are noted to value the beliefs and behaviours that contribute to their illness rather than regarding them as problematic, which interferes with screening, prevention and early intervention. Involving the family to support interventions early in the course of the illness can produce sustained changes; however, those with a severe and/or protracted illness might require inpatient nursing support and/or outpatient psychotherapy. Prevention programmes aim to moderate the overvaluation of 'thinness' and body dissatisfaction as one of the proximal risk factors. The low prevalence of AN limits the ability to identify risk factors and to study the timing and sex distribution of the condition. However, genetic profiles, premorbid features, and brain structures and functions of patients with AN show similarities with other psychiatric disorders and contrast with obesity and metabolic disorders. Such studies are informing approaches to address the neuroadaptation to starvation and the other various physical and psychosocial deficits associated with AN. This Primer describes the epidemiology, diagnosis, screening and prevention, aetiology, treatment and quality of life of patients with AN.

Abstract
IMPORTANCE Milk consumption during adolescence is recommended to promote peak bone mass and thereby reduce fracture risk in later life. However, its role in hip fracture prevention is not established and high consumption may adversely influence risk by increasing height. OBJECTIVES To determine whether milk consumption during teenage years influences risk of hip fracture in older adults and to investigate the role of attained height in this association. DESIGN, SETTING, AND PARTICIPANTS Prospective cohort study over 22 years of follow-up in more than 96,000 white postmenopausal women from the Nurses' Health Study and men aged 50 years and older from the Health Professionals Follow-up Study in the United States. EXPOSURES Frequency of consumption of milk and other foods during ages 13 to 18 years and attained height were reported at baseline. Current diet, weight, smoking, physical activity, medication use, and other risk factors for hip fractures were reported on biennial questionnaires. MAIN OUTCOMES AND MEASURES Cox proportional hazards models were used to calculate relative risks (RRs) of first incidence of hip fracture from low-trauma events per glass (8 fl oz or 240 mL) of milk consumed per day during teenage years. RESULTS During follow-up, 1226 hip fractures were identified in women and 490 in men. After controlling for known risk factors and current milk consumption, each additional glass of milk per day during teenage years was associated with a significant 9% higher risk of hip fracture in men (RR = 1.09; 95% CI, 1.01-1.17). The association was attenuated when height was added to the model (RR = 1.06; 95% CI, 0.98-1.14). Teenage milk consumption was not associated with hip fractures in women (RR = 1.00 per glass per day; 95% CI, 0.95-1.05). CONCLUSIONS AND RELEVANCE Greater milk consumption during teenage years was not associated with a lower risk of hip fracture in older adults. The positive association observed in men was partially mediated through attained height.

Abstract
Anorexia nervosa is a serious psychiatric disorder accompanied by high morbidity and mortality. It is characterized by emaciation due to self-starvation and displays a unique hormonal profile. Alterations in gonadal axis, growth hormone resistance with low insulin-like growth factor I levels, hypercortisolemia and low triiodothyronine levels are almost universally present and constitute an adaptive response to malnutrition. Bone metabolism is likewise affected resulting in low bone mineral density, reduced bone accrual and increased fracture risk. Skeletal deficits often persist even after recovery from the disease with serious implications for future skeletal health. The pathogenetic mechanisms underlying bone disease are quite complicated and treatment is a particularly challenging task.

Abstract
Eating disorders are associated with a multitude of metabolic abnormalities which are known to adversely affect bone metabolism and structure. We aimed to comprehensively review the literature on the effects of eating disorders, particularly anorexia nervosa (AN), on bone metabolism, bone mineral density (BMD), and fracture incidence. Furthermore, we aimed to highlight the risk factors and potential management strategies for patients with eating disorders and low BMD. We searched the MEDLINE/OVID (1950-July 2011) and EMBASE (1980-July 2011) databases, focussing on in vitro and in vivo studies of the effects of eating disorders on bone metabolism, bone mineral density, and fracture incidence. Low levels of estrogen, testosterone, dehydroepiandrosterone, insulin-like growth factor-1 (IGF-1), and leptin, and high levels of cortisol, ghrelin, and peptide YY (PYY) are thought to contribute to the 'uncoupling' of bone turnover in patients with active AN, leading to increased bone resorption in comparison to bone formation. Over time, this results in a high prevalence and profound degree of site-specific BMD loss in women with AN, thereby increasing fracture risk. Weight recovery and increasing BMI positively correlate with levels of IGF-1 and leptin, normalisation in the levels of cortisol, as well as markers of bone formation and resorption in both adolescent and adult patients with AN. The only treatments which have shown promise in reversing the BMD loss associated with AN include: physiologic dose transdermal and oral estrogen, recombinant human IGF-1 alone or in combination with the oral contraceptive pill, and bisphosphonate therapy.

Abstract
UNLABELLED Bone mineral density (BMD; measured by DXA) changes were observed at all sites at 1 year in 146 patients with anorexia nervosa. Four independent factors accounted for the variation in BMD at the spine: duration of anorexia, bone-specific alkaline phosphatase (BAP), cross-linked carboxyterminal telopeptide region of type I collagen (ICTP), and triiodothyronine (T3). No change in BMD was observed from 1 to 2 years during follow-up. INTRODUCTION The purpose of this study was to assess changes in BMD at 1 and 2 years in anorexia nervosa patients, and to explore the relationships between change in BMD and various clinical and biological parameters measured at the first visit. METHODS BMD was measured in anorexia nervosa patients at inclusion, at 1-year follow-up (n = 146) and at 2-year follow-up (n = 89). RESULTS Bone loss was observed at all sites at 1 year. When multivariate analyses were performed, four independent factors accounted for the variation in BMD at the spine: duration of anorexia nervosa, BAP, ICTP, and T3. At the total hip site, leptin level was the main factor accounting for the variation in BMD. Strong correlations were also observed between weight at 1 year and change in BMD at 2 years. At the 2-year follow-up, no significant change in BMD was observed at the spine or femoral neck. In patients who were no longer amenorrheic at 1 year, a significant improvement in BMD at 2 years was observed at the total hip (+1.2%, p = 0.02) and femoral neck (+3.7%, p = 0.02). Similarly, in patients with a body mass index >17 kg/m(2) at 1 year, an improvement in BMD at the total hip at 2 years was observed (+3%, p = 0.02) CONCLUSION Bone loss in anorexia nervosa patients occurs at an early stage, and the factors influencing such are different at the spine and hip.

Abstract
The aim of this study was to study long-term outcome of physical health and self-injurious behaviour (SIB) in anorexia nervosa (AN). Fifty-one adolescent-onset AN cases, originally recruited after community screening, and 51 matched controls (COMP) were interviewed regarding somatic problems and SIB and physically examined 18 years after AN onset, at mean age 32 years. Six individuals had an eating disorder (ED). No one had died. The AN group weighed less than the COMP group. The frequency of somatic problems did not differ between groups. Dental enamel lesions and shorter than expected stature occurred only in the AN group. Dysdiadochokinesis was overrepresented in the AN group and age of AN onset was lower among those with the neurological deficit. Severe SIB occurred only in the AN group, predominantly during adolescence. To conclude, somatic problems were common in both groups. Most individuals in the AN group had recovered from their ED, but weight revealed a persistent restricted eating behaviour.

Abstract
BACKGROUND AND AIMS There still is a lack of prospective studies on bone mineral development in patients with a history of early onset Anorexia nervosa (AN). Therefore we assessed associations between bone mass accrual and clinical outcomes in a former clinical sample. In addition to an expected influence of regular physical activity and hormone replacement therapy, we explored correlations with nutritionally dependent hormones. METHODS 3-9 years (mean 5.2 +/- 1.7) after hospital discharge, we re-investigated 52 female subjects with a history of early onset AN. By means of a standardized approach, we evaluated the general outcome of AN. Moreover, bone mineral content (BMC) and bone mineral density (BMD) as well as lean and fat mass were measured by dual-energy x-ray absorptiometry (DXA). In a substudy, we measured the serum concentrations of leptin and insulin-like growth factor-I (IGF-I). RESULTS The general outcome of anorexia nervosa was good in 50% of the subjects (BMI >/= 17.5 kg/m2, resumption of menses). Clinical improvement was correlated with BMC and BMD accrual (chi2 = 5.62/chi2 = 6.65, p = 0.06 / p = 0.036). The duration of amenorrhea had a negative correlation with BMD (r = -.362; p < 0.01), but not with BMC. Regular physical activity tended to show a positive effect on bone recovery, but the effect of hormone replacement therapy was not significant. Using age-related standards, the post-discharge sample for the substudy presented IGF-I levels below the 5th percentile. IGF-I serum concentrations corresponded to the general outcome of AN. By contrast, leptin serum concentrations showed great variability. They correlated with BMC and current body composition parameters. CONCLUSIONS Our results from the main study indicate a certain adaptability of bone mineral accrual which is dependent on a speedy and ongoing recovery. While leptin levels in the substudy tended to respond immediately to current nutritional status, IGF-I serum concentrations corresponded to the individual's age and general outcome of AN.

Association of macrophage inhibitory cytokine-1 with nutritional status, body composition and bone mineral density in patients with anorexia nervosa: the influence of partial realimentation. Nutr Metab (Lond) 2010; 7:34.

Abstract
Background Macrophage inhibitory cytokine-1 (MIC-1) is a key inducer of cancer-related anorexia and weight loss. However, its possible role in the etiopathogenesis of nutritional disorders of other etiology such as anorexia nervosa (AN) is currently unknown. Methods We measured fasting serum concentrations of MIC-1 in patients with AN before and after 2-month nutritional treatment and explored its relationship with nutritional status, metabolic and biochemical parameters. Sixteen previously untreated women with AN and twenty-five normal-weight age-matched control women participated in the study. We measured serum concentrations of MIC-1 and leptin by ELISA, free fatty acids by enzymatic colorimetric assay, and biochemical parameters by standard laboratory methods; determined resting energy expenditure by indirect calorimetry; and assessed bone mineral density and body fat content by dual-energy X-ray absorptiometry. ANOVA, unpaired t-test or Mann-Whitney test were used for groups comparison as appropriate. The comparisons of serum MIC-1 levels and other studied parameters in patients with AN before and after partial realimentation were assessed by paired t-test or Wilcoxon Signed Rank Test as appropriate. Results At baseline, fasting serum MIC-1 concentrations were significantly higher in patients with AN relative to controls. Partial realimentation significantly reduced serum MIC-1 concentrations in patients with AN but it still remained significantly higher compared to control group. In AN group, serum MIC-1 was inversely related to Buzby nutritional risk index, serum insulin-like growth factor-1, serum glucose, serum total protein, serum albumin, and lumbar bone mineral density and it significantly positively correlated with the duration of AN and age. Conclusions MIC-1 concentrations in AN patients are significantly higher relative to healthy women. Partial realimentation significantly decreased MIC-1 concentration in AN group. Clinical significance of these findings needs to be further clarified.

Abstract
OBJECTIVE To systematically review the evidence supporting treatment of osteopenia and osteoporosis in patients with anorexia nervosa (AN). DATA SOURCES We identified controlled clinical studies of interventions for low bone mass in AN via searches of MEDLINE; the Cochrane Library; EMBASE; PsycINFO; and cumulative index to nursing and allied health literature. Outcomes of interest were changes in bone mineral density and fracture incidence. RESULTS Six randomized controlled trials (RCTs) and two cohort trials examined five classes of medical therapy on bone mineral density outcomes. One RCT of bisphosphonates showed no benefit and a second flawed RCT showed some benefit; one RCT showed a benefit of insulin-like growth factor-I; none of the five trials evaluating estrogen therapy showed benefit. DISCUSSION Although patients with AN are often losing bone mass when they should be optimizing bone growth, there is no good evidence to guide medicinal interventions. Therefore, early detection and weight restoration are of utmost importance whereas ongoing trials define effective therapies.

Abstract
The Task Force focusing on the use of dual energy X-ray absorptiometry (DXA) in children and adolescents with diseases that may affect the skeleton reviewed over 300 articles to establish the basis for the Official Positions. A significant number of studies used DXA-based outcome measures to assess the effects of specific interventions and charted the natural history of incremental changes in bone size and mass in specific disease states in children. However, the utility of DXA in clinical practice has not been evaluated systematically, in large part due to the lack of a workable definition for childhood osteoporosis. Thus, in combination with the Official Positions addressing the diagnosis of osteoporosis in children, and the reporting of DXA results in children, this document presents clear guidelines from which clinicians and researchers alike can work. This report delineates a set of disorders in which it is appropriate to use DXA as part of the comprehensive assessment of skeletal health in children and adolescents, and provides guidance concerning the initiation of assessment and the frequency of monitoring. Importantly, this document also highlights significant gaps in our knowledge, emphasizing areas for future research.

Abstract
PURPOSE To evaluate the dental and periodontal health of adolescents and young women with restrictive anorexia nervosa (AN), and relationship between bone mineral density (BMD) assessed by dual energy Xray absorptiometry (DXA) and dental radiographs. STUDY DESIGN Twenty-three young women, median age 17.6 years (range 14.4-27.2), were studied within three months of entering a clinical trial. DXA BMD measurements were obtained and subjects underwent a comprehensive dental examination, including panoramic and bitewing dental radiographs. Three observers assessed mandibular cortical width (MCW) in the mental foramen region on panoramic radiographs. RESULTS Dental findings included very good to excellent oral hygiene. Gingival recession was evident in 10 participants (43%). Dental erosion was not seen and the mean decayed missing or filled teeth (DMFT) was 8.6. There was a weak positive correlation between BMD by DXA and MCW on radiographs. CONCLUSIONS We report dental manifestations associated with restrictive AN, and the association between bone assessments by DXA and dental radiographs in this patient group. Despite subnormal DXA measurements in most patients, essentially all adolescents had a normal dental examination. Dental providers should be cognizant of the fact that many patients with eating disorders may not display the "classic" findings reported in the literature.

Abstract
Osteopenia and osteoporosis are complications of adolescent anorexia nervosa (AN) and may result in a permanent deficit of bone mass in adulthood. It is still unclear if a complete catch-up in bone mineral density (BMD) is possible after weight rehabilitation in AN. METHODS. We investigated bone formation (bAP, PICP), bone resorption (CTX) and BMD (lumbar spine, femoral neck) along with endocrinological parameters in 19 girls with AN (14.4 +/- 1.6 years) and in 19 healthy controls for 2 years after inpatient re-feeding. RESULTS. Re-feeding normalised bone formation activity in patients. The pattern of bone turnover in patients after 2 years was similar to the pattern healthy controls had shown 2 years before. BMD of patients was significantly lower than in controls and did not change throughout the entire study. CONCLUSIONS. Weight rehabilitation leads to prolonged normalization of bone turnover in adolescent AN. Since we could not observe a "catch up" effect in BMD of girls with AN in a 2-year follow-up, BMD of these patients needs to be carefully monitored until adulthood to detect early osteoporosis.

Abstract
To our knowledge anorexia nervosa (AN) adversely influences bone density, but whether qualitative characteristics of bone are also affected is not known. For this reason we investigated prospectively the changes in skeletal status in a population of 18 adolescent girls with AN aged 11.5-18.1 years (mean 15.9+/-1.9 years) using both dual-photon X-ray absorptiometry (DXA) and quantitative ultrasound (QUS) measurements, bone turnover markers (osteocalcin, bone alkaline phosphatase - bALP, carboxy-terminal cross-linked telopeptide of type I collagen - ICTP), and laboratory investigations (serum total and ionised calcium, serum phosphate, urine calcium/creatinine ratio, luteinizing hormone - LH, follicle-stimulating hormone - FSH, estradiol). Measurements of bone mineral density at the spine (s-BMD) and total body (TB-BMD) and amplitude-dependent speed of sound (Ad-SOS) of the hand phalanges were performed at baseline, 7.8+/-2.4 and 19.4+/-5.6 months of follow-up. The mean values of TB-BMD, s-BMD and Ad-SOS measurements did not change during the period of observation. The mean Z-scores for TB-BMD and Ad-SOS were significantly lower after 19.4 months of observation vs. baseline (-1.06+/-1.00 vs. -0.67+/-0.98 vs. and -0.50+/-0.88 vs. 0.26+/-1.75, respectively). Z-scores for s-BMD decreased non-significantly (p=0.08). Among bone turnover markers, we observed a significant increase in bALP and a non-significant increase in osteocalcin serum concentrations which were below normal ranges for age, sex and Tanner stage at baseline. High baseline serum ICTP concentration decreased non-significantly, reaching normal ranges during the observation. We conclude that anorexia nervosa seriously affects skeletal status in adolescent girls. Bone turnover markers analysed together with densitometric parameters suggest that AN influences both bone formation and resorption processes. QUS measurements at hand phalanges may be an appropriate method in the evaluation of skeletal status in patients with AN.

Abstract
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.

Abstract
Anorexia nervosa and diet-induced amenorrhea have an important impact not only on gynecological health but also on bone mass, especially if the disease is not promptly recognized and treated. This is particularly important because these conditions usually arise in adolescence, when peak bone mass is normally achieved. In this article we discuss the therapeutic issues related to bone loss associated with eating disorders.

Abstract
PURPOSE To examine changes in bone mineral density (BMD) and bone mineral content (BMC) in relation to pharmacological and nutritional interventions in a distance runner diagnosed with the female athlete triad of disordered eating, amenorrhea, and osteoporosis. METHODS BMD of the lumbar spine (L2-L4) and total proximal femur were measured from ages 22.9 to 30.8 yr using dual x-ray absorptiometry (DXA). RESULTS At age 22.9, the patient presented with primary amenorrhea, low body weight (BMI: 15.8 kg.m(-2)), and low BMD in the spine (74% of normal, T score: -2.50) and hip (80% of normal, T score: -1.54). For the next 2 yr, the patient took oral contraceptives to induce menses, but continued to maintain a low weight. Her BMD remained unchanged. At age 25.1 yr, she decided to gain weight and improve her nutrition, resulting in small increases in spinal BMD (+1.1%), hip BMD (+1.6%), and total body BMC (+7.6%) in 4 months. From ages 25.4 to 30.8 yr, the patient continued to gain weight, eventually reaching a healthy BMI of 21.3 kg.m(-2); correspondingly, since baseline, her BMD had increased 25.5% in the spine and 19.5% in the hip, bringing her BMD to within normal values (spine: 94% of normal, hip: 96% of normal). CONCLUSION This case illustrates that even if skeletal development is interrupted in adolescence, there is still the potential for "catch-up" in BMD well into the third decade of life. Reversal of large bone density deficits in this patient can be attributed to improved nutrition and weight gain but not to hormone replacement.

Abstract
Osteoporosis is a serious complication of anorexia nervosa and in affected adolescents may result in a permanent deficit in bone mass. The pathophysiology of this bone disease has not been clearly defined. In this prospective study of 26 young women with anorexia nervosa aged 13-20 years (mean 16.5) we have measured changes in bone mineral density, total body composition and biochemical indices of bone turnover over 1 year. Over this period there was a mean weight gain of 10 kg and significant height gain with baseline and final values for body mass index of 14.2+/-1.7 and 17.6+/-2.3 kg/m2 (P<0.001). However, no significant changes were seen in bone mineral density in the spine or proximal femur during the study; total body bone mineral content was significantly higher than baseline at 3 months and 12 months (P=0.001 and P<0.0001), but total body bone mineral density at 3 months was significantly lower than baseline (P=0.003). Serum osteocalcin and bone-specific alkaline phosphatase values increased significantly and remained higher than baseline at all time points whereas urinary NTX/creatinine excretion showed a non-significant increase over the first 6 months of the study, but at 12 months, the mean value was significantly lower than baseline. Mean serum 25-hydroxyvitamin D levels showed a significant decrease at 6 months (P<0.05), but returned towards baseline thereafter. There was a significant increase in serum parathyroid hormone levels at all time points compared to baseline, these occurring within the normal range. These results indicate that although weight gain in young anorexics is associated with linear growth, bone mineral density does not increase. Whether this deficit can be corrected subsequently requires longer-term prospective studies.

Abstract
Anorexia nervosa (AN) is a condition of self-induced weight loss, associated with an intense fear of gaining weight. Previous studies have shown that bone density may increase with regaining and maintaining normal weight; however, relatively little is known about the changes in bone metabolism that occur during weight restoration. We describe the effect of weight restoration and maintenance of weight over 1 year on bone mineral density (BMD) and bone turnover. We recruited women from the eating disorders services at the South West London and St George's Mental Health NHS Trust, and the Priory and Charter Nightingale Hospitals in London, UK. Details of their AN, fracture history, menstrual history and exercise were obtained by interview and case note review. Morning samples of blood and second void urine were taken for biochemical analysis. BMD was measured by DXA at the lumbar spine (LS), femoral neck (FN), distal radius (RD) and total body bone mineral content (BMC). Patients then entered the treatment program, which includes re-feeding, dietary education and psychotherapy. Over a period of 42 months, we recruited 55 women who agreed to participate in this study and underwent baseline investigations. Of these, 15 (27%) subjects achieved and then maintained their target weight for the duration of the study. At baseline for all subjects (n=55) estradiol levels were lower than the normal reference ranges (both follicular and luteal phases) in 91% of the women. Bone specific alkaline phosphatase (BSAP) concentrations were lower than the premenopausal reference range in 55% of women, and urinary deoxypyridinoline (DPD) was above the premenopausal reference range in 78% of women. Baseline lumbar spine BMD was positively related to BMI (Pearson's r=0.29, P=0.04) and inversely related to bone turnover markers: urinary DPD (Pearson's r=-0.39, P=0.01 and serum BSAP (Pearson's r=-0.3, P=0.06). The 15 patients who regained and maintained weight were followed-up for a mean duration of 69 weeks (SD 7.3, range 54 to 84 weeks). Mean BMI increased from 14.2 (1.7) to 20.2 (0.77) kg/m2 and remained stable throughout follow-up. Menstruation resumed in 8 of the 15 women. Total body BMC and LS BMD increased significantly over the duration of follow-up (by 4.3% each), but FN BMD and distal radius remained stable. Lumbar spine bone area also increased significantly, whereas FN and distal radius did not. These changes were associated with a significant increase in BSAP (P=0.01), and a non-significant trend for a decrease in DPD (P=0.10). Our findings suggest that when women are at low body weight they are in a hypo-estrogenic state, which is associated with imbalance of bone turnover (high bone resorption and low bone formation). This is reversed with weight gain and persists as target weight is maintained and is associated with increases in BMC and BMD.

Abstract
The objective of this study was to evaluate the epidemiology, diagnosis, pathophysiology, and treatment of bone loss related to anorexia nervosa. Earlier onset and longer duration of anorexia nervosa are associated with more severe bone loss. Osteoporosis develops in 38-50% of cases. Bone mineral density measurement by dual-energy X-ray absorptiometry is useful for assessing bone mass, and bone marker assays provide information on bone turnover. Bone loss in anorexia nervosa is probably multifactorial. Estrogen deficiency was long felt to be the major factor. However, in contrast to postmenopausal osteoporosis, bone loss associated with anorexia nervosa is related mainly to inadequate bone formation, with only a slight increase in bone resorption. This suggests a role for nutritional factors, such as disturbances in the growth hormone-somatomedin C axis (GH/IGF-I) related to malnutrition. The best treatment strategy for correcting bone mass in patients with anorexia nervosa is not agreed on. Resumption of menstrual cycles and weight gain seem necessary but not always sufficient. Studies found no benefits with estrogen therapy, but this was usually given as estrogen-progestin contraceptives. No vast studies evaluating hormone replacement therapy have been reported. Bone formation enhancers such as IGF-I seem to provide the best results, most notably when used in combination with estrogens. This suggests that complex treatment strategies combining bone formation enhancers and bone resorption inhibitors may deserve evaluation.

Abstract
CONTEXT Both anorexia nervosa (AN) and depression are associated with osteoporosis. We hypothesized that adolescent girls with AN and depression will have lower bone mineral density (BMD) than anorexic girls without depression. OBJECTIVE The objective of this study was to investigate whether depression is an independent risk factor for osteoporosis in anorexic adolescent girls. DESIGN This study was cross-sectional. SETTING This study was conducted at the University Children's Hospital (Bialystok, Poland) from October 2002 through September 2003. PARTICIPANTS Forty-five Caucasian anorexic girls aged 13-23 yr, matched by age, Tanner stage, weight, height, calcium intake, and duration of AN, were studied, including 14 with comorbid depression (based on Hamilton Depression Rating Scale and Montgomery-Asberg Depression Rating Scale) and 31 anorexic girls without depression. MAIN OUTCOME MEASURES Total body and lumbar spine (LS) BMD, fat mass, and lean mass assessed using dual-energy x-ray absorptiometry were compared between AN girls with and without depression. RESULTS BMD was reduced in both groups, relative to reference data, but girls with AN and depression had lower BMD than those with AN alone (LS Z-scores, -2.6 +/- 0.3 vs. -1.7 +/- 0.3; P = 0.02) (mean +/- sem). Quantitative assessment of depression correlated independently with total body BMD (r = -0.4; P < 0.05) and LS BMD (r = -0.6; P < 0.001). CONCLUSION Anorexic girls with depression are at higher risk of osteoporosis than those without depression. The mechanisms responsible for decreased BMD in depression are not known. Independent treatment of the depressive disorder in AN may partly alleviate the bone fragility.

Abstract
Calcium supplementation has been shown to increase bone mineralization in children and adolescents. However, catch-up mineralization later in puberty appears likely if intake is consistent with usual average intakes in the United States. Ultimately, individualized risk assessment will be developed based on genetic and lifestyle factors that can be used to guide optimal calcium intake during childhood.

Abstract
BACKGROUND Body image distortions are a core feature of anorexia nervosa (AN). Increasing evidence suggests that the fat distribution immediately after weight restoration in patients with AN differs from the distribution typical of healthy adult women. OBJECTIVE The purpose of this study was to assess body fat distribution before and shortly after normalization of weight in women with AN. DESIGN Body composition and fat distribution were assessed by anthropometry, dual-energy X-ray absorptiometry, and whole-body magnetic resonance imaging in 29 women with AN before and after weight normalization and at a single time point in 15 female control subjects. Hormone concentrations were also evaluated in patients and control subjects. RESULTS During approximately 10.1 +/- 2.9 wk (range: 4-17.3 wk) of treatment, patients with AN gained 12.2 +/- 3.6 kg, and refed weight (54.1 +/- 4.2 kg) did not differ significantly from that of control subjects (54.7 +/- 4.4 kg). Waist-to-hip circumference ratio (P < 0.006), total trunk fat (P < 0.003), visceral adipose tissue (P < 0.006), and intramuscular adipose tissue (P < 0.003) were significantly greater in the weight-recovered patients than in the control subjects. In contrast, after refeeding, total subcutaneous adipose tissue and skeletal muscle mass did not differ significantly between the patients and control subjects. In patients with AN, serum cortisol decreased and serum estradiol increased significantly with refeeding but not to control concentrations. CONCLUSIONS In women with AN, normalization of weight in the short term is associated with an abnormal distribution of body fat. The implications of these findings for the long-term psychological and physical health of women with AN are unknown.

Abstract
Amenorrhea is a hallmark sign of anorexia nervosa. Its cause is multifactorial and its resolution necessitates treatment of the underlying eating disorder. The neuroendocrine changes associated with menstrual abnormalities in underweight and weight recovered anorexia nervosa, recent research on osteopenia, and treatment recommendations are addressed.
