Osteoporosis in eating disorders: a follow-up study of patients with anorexia and bulimia nervosa

This study prospectively investigated the course of bone mineral density (BMD) in patients with anorexia nervosa (AN) and bulimia nervosa (BN) over a 3.6-yr follow-up period. From an initial sample of 47 female patients with an eating disorder (T1), 38 (n = 24 AN; n = 14 BN) were reassessed at follow-up (T2) (participation rate, 80.1%). For nonrecovered AN patients at T2, prevalence rates of osteopenia (-1.0 SD > or = T-score > -2.5 SD) and osteoporosis (T-score < or = -2.5 SD) at the lumbar spine were 54.2 and 20.8%, respectively. Due to an annual loss of lumbar spine BMD (-3.7 +/- 4.9%) in the chronic AN patients and a slight but insignificant annual increase (0.7 +/- 1.7%) for those who recovered, the difference in BMD between both outcome groups was more pronounced at follow-up (0.93 +/- 0.13 vs. 1.14 +/- 0.13 g/cm2; P < 0.01). Nonrecovered AN patients with binge eating/purging type showed a significantly reduced BMD compared with patients with the restricting type (0.87 +/- 0.13 vs. 1.02 +/- 0.08 g/cm2; P = 0.02). Both at baseline and follow-up, AN patients had increased rates of bone resorption, as measured by urinary desoxypyridinoline, compared with a control group (n = 42) (11.4 +/- 4.4 vs. 10.4 +/- 7.8, P < 0.001, vs. 5.6 +/- 2.4 and 10.4 +/- 7.8 nM/mM creatinine, P < 0.05, respectively). The subtype of AN and body mass index were best predictors for BMD at the lumbar spine at follow-up (R2 = 0.576). With one exception, all bulimic patients had BMD and markers of bone turnover within the normal range. These results suggest that patients with chronic AN, particularly of the binge eating/purging type, are at high risk for osteoporosis and may need additional therapy to prevent bone loss.

Cross-Cultural Research on Anorexia Nervosa: Assumptions Regarding the Role of Body Weight

OBJECTIVE

To critically examine two assumptions guiding cross-cultural research on the weight concerns of anorexia nervosa: (1) that weight concerns are specific to contemporary, Western manifestations of the disorder and (2) that the dissemination of Western values regarding thinness is primarily responsible for the development of anorexia nervosa in non-Western contexts.

METHOD

A review of theoretical and empirical literature on cross-cultural aspects of anorexia nervosa and the medical records of 14 Asian patients treated for eating disorders in Sydney, Australia.

RESULTS AND DISCUSSION

Regarding the first assumption: It is argued that weight concerns when defined as weight loss that is positively valued (rather than a fat phobia) is a defining characteristic of anorexia nervosa and is not limited to contemporary, Western cases of the disorder. Regarding the second assumption: It is argued that the occurrence of anorexia nervosa in non-Western contexts cannot be solely attributed to the acceptance of Western thinness ideals because values and practices intrinsic to non-Western cultures are also likely to be etiologically relevant.

Altered energy metabolism in anorexia nervosa

Optimal nutritional rehabilitation of anorexia nervosa requires more information concerning actual energy and substrate requirements. To this end, indirect calorimetry was performed in female patients (n=34, age 20.9+/-1.2 yr, body mass index [BMI] 15.6+/-0.2 kg/m(2); mean+/-SEM) soon after commencement of refeeding and at the time of discharge from hospital (n=18, BMI 19.0+/-0.3 kg/m(2)). Healthy female controls (n=18, age 24.6+/-1.3 yr, BMI 21.6+/-0.6 kg/m(2)) were also tested. Resting energy expenditure (REE) and respiratory quotient (RQ) were measured in the fasting state, followed by diet-induced thermogenesis (DIT) and RQ over a 4 h period following a 100 g oral glucose load. Compared with post-refeeding patients and controls, pre-refeeding patients had a high basal RQ and a low REE, with a paradoxically higher DIT (13.2+/-0.9% of REE vs. 8.3+/-1.2% and 8.6+/-0.9% in post-refeeding patients and controls, respectively). RQ values in pre-refeeding patients exceeded unity following the glucose load, probably reflecting net lipogenesis, whereas in the post-refeeding patients, post-glucose RQ was similar to that of controls, suggesting premature curtailment of lipogenesis. These data demonstrate energy wasting in emaciated patients with anorexia nervosa. Biological repair processes could account for disproportionate energy loss early in refeeding and there may be some later impediment to full restoration of fat stores.

Perceived expressed emotion in the siblings and parents of hospitalized patients with anorexia nervosa

OBJECTIVE

The present study investigated the relationship between the level of perceived Expressed Emotion (EE) of the siblings and parents of patients hospitalized with anorexia nervosa and its effect on weight gain and psychological functioning.

METHOD

The Level of Expressed Emotion (LEE) Scale was administered on admission to 19 patients with anorexia nervosa who completed the LEE three times so as to identify their perceptions of their relationship with their closest age sibling, mother, and father. They were also required to complete the Eating Disorder Inventory 2 (EDI-2). Patients' closest age sibling completed the Family Attitude Scale (FAS). The patients' body mass index (BMI) was calculated 6 weeks later, and the EDI-2 readministered.

RESULTS

Perceived EE was not predictive of BMI change after 6 weeks of hospitalization. A composite perceived family EE score was a significant predictor of change on the Interpersonal Distrust, Maturity Fears, and Perfectionism subscales of the EDI-2.

DISCUSSION

These findings suggest that patients' perceptions of their relationships with their closest aged sibling, mother, and father are poor predictors of weight gain and improvement in psychological functioning following 6 weeks of inpatient treatment.

Fluid restriction in anorexia nervosa: a neglected symptom or new phenomenon?

OBJECTIVE

The deliberate restriction of fluids to control weight is even more dangerous than food restriction since it results in several serious medical complications. However, there has been scant attention given to the anorexia nervosa patient's manipulation of fluids. It is our clinical impression that fluid restriction in this illness is more common than previously thought.

METHOD

We summarize the demographic and clinical features of six cases of anorexia nervosa and one case of eating disorder not otherwise specified (ED-NOS) (subthreshold anorexia nervosa), where fluid restriction was a major behavioral problem. We then describe two of the anorexia nervosa cases in more detail. All were treated at a dieting disorders unit affiliated with the University of Sydney. Their preadmission history, psychological and physical status on admission, results of physical investigations, the beginning of the fluid restriction, fluid and food intake throughout treatment, and the resolution of the fluid restriction were assessed.

RESULTS

Patterns emerged in the relationship between eating and drinking. In all cases, food restriction was severe prior to the onset of fluid restriction but, notably, fluid intake recommenced prior to food intake. The reasons given by patients for restricting fluid were that it contained calories and that it made them feel full. Most anorexic patients equate feeling full with "feeling fat." Furthermore, they feel fully in control when they restrict fluid as well as food and this produces a strong motivation to maintain the behavior.

DISCUSSION

The cases illustrate the insidious nature and serious consequences of fluid restriction and the difficulties managing dieting-disordered patients who undertake it. Careful attention must be given to assessment and clinicians should be aware of fluid restriction as an important aspect of anorexic behavior.

Measuring self-esteem in dieting disordered patients: the validity of the Rosenberg and Coopersmith contrasted

OBJECTIVE

In order to ascertain the most appropriate measure of self-esteem for dieting disordered patients, this study contrasted the construct and convergent validities of two widely used measures. In addition, dieting disordered subgroups were compared on levels of self-esteem.

METHOD

One hundred and seventeen male and female patients diagnosed with anorexia nervosa, bulimia nervosa, or eating disorder not otherwise specified completed the Rosenberg Self-Esteem Scale (SES), the Coopersmith Self-Esteem Inventory (SEI), and measures of dieting disorder pathology and depression.

RESULTS

No significant differences among the three dieting disorder subgroups were found. In determining convergent validity, regression analyses indicated that the SES was a significant predictor of dieting disorder psychopathology whereas the SEI was not. Of the two self-esteem measures, only the SES showed evidence of convergent validity.

DISCUSSION

The results suggest that the SES has sounder construct and convergent validity than the SEI. Hence, the SES may be more appropriate for use with dieting disordered populations.

Bulimia nervosa, restrained, and unrestrained eaters: a comparison of non-binge eating behavior

OBJECTIVE

This study investigated non-binge eating behavior in bulimia nervosa, restrained and unrestrained eaters.

METHOD

Nine females with bulimia nervosa, 12 female restrained eaters, and 13 female unrestrained eaters were administered the Eating Disorder Inventory-2 (EDI-2), the Body Shape Questionnaire, the Beck Depression Inventory, the Rosenberg Self-Esteem Scale, and the Revised Restraint Scale (RRS). All subjects were videotaped during a midday meal and their eating behavior was subsequently rated using the Eating Behaviour Rating Scale (EBRS).

RESULTS

EBRS ratings were higher for bulimic than for unrestrained subjects. Restrained subjects' ratings did not differ from those of either bulimic or unrestrained subjects. EBRS scores were positively correlated with RRS and EDI-2 total scores.

CONCLUSIONS

Bulimic subjects display aberrant eating behavior, and the extent to which subjects engage in maladaptive eating behavior is related to the degree of eating pathology. These results support the utility of the EBRS as a useful index of eating behaviors in clinical and nonclinical populations.

Is there a relationship between bulimia nervosa and hazardous alcohol use?

OBJECTIVE

The present study investigates the relationship between hazardous alcohol consumption and bulimia nervosa in a clinical population.

METHOD

The Alcohol Use Disorders Identification Test (AUDIT) was administered to two groups of female subjects: patients with bulimia nervosa (n = 30) and nonbulimic controls (n = 15). These two groups were further subdivided on the basis of personality disorder as assessed by the Personality Disorder Examination (PDE), a comprehensive interview covering all of the criteria for the 13 DSM-III-R Axis II disorders. The bulimic patients were referred to a dieting disorders clinic affiliated with the University of Sydney. All met DSM-III-R criteria for bulimia nervosa and all had Body Mass Indices (BMIs) greater than 19. The nonbulimic control group were recruited from an undergraduate psychology course. All subjects were given the Bulimic Investigatory Test, Edinburgh (BITE) and the Eating Disorders Inventory-2 (EDI-2).

RESULTS

66.7% (8/12) of personality disordered bulimic patients were drinking at hazardous levels whereas 61.1% (11/18) of bulimic patients without a personality disorder were doing likewise. Furthermore, 35.7% (5/14) of the nonbulimic controls without personality disorders were drinking at hazardous levels and the only control subject with a personality disorder was doing likewise. The association between personality disorder diagnosis and hazardous alcohol use in the bulimic sample just failed to reach significance at the 5% level (chi 2 1,upper .05 = 3.84, p = .052). No association between Axis 1 diagnosis of bulimia nervosa and hazardous alcohol use was found (chi 2 1,upper .05 = 3.84, p = .52).

DISCUSSION

The results of the present study suggest we may need to rethink the relationship between hazardous alcohol use and bulimia nervosa reported in the literature, as it may be an artifact of the relationship between personality disorder and hazardous alcohol consumption. Further research is necessary to clarify this issue.

Perceptions of bed rest by anorexic patients

OBJECTIVE

Few studies have investigated perceptions of operant conditioning programs by anorexic patients. This study examined patients' perceptions of the Bed Rest (BR) component which is employed in some operant conditioning programs.

METHODS

A sample of 48 anorexic inpatients was administered a survey to elicit their attitudes towards BR.

RESULTS

Results from the survey suggested that most patients perceived BR in a negative way. The main complaint, however, was not punishment or humiliation, as predicted, but isolation and boredom. A number of patients concluded that they wanted more individualization and distraction and less restriction while on BR.

DISCUSSION

The findings justify the use of BR within a humane framework in the inpatient treatment of anorexia nervosa, but suggest that patients' perceptions of BR warrant systematic scrutiny.

Attentional biases in eating disorders: a visual probe detection procedure

OBJECTIVE

To investigate attentional biases for body shape and weight-related stimulus words among subjects with anorexia nervosa, bulimia nervosa, and control subjects classified using a measure of dietary restraint.

METHODS

A visual probe detection task was used to assess attention toward stimulus words reflecting either a thin or a large physique and positively or negatively valenced emotion words.

RESULTS

In comparison to controls, subjects with eating disorders detected target probes more slowly when they appeared in the same location as had stimulus words connoting a thin physique. In addition, there was a trend toward faster detection or target probes that appeared in the same location as had stimulus words connoting a large physique. Neither of these effects were observed among restrained eaters.

DISCUSSION

Our results extend prior work suggesting information-processing biases for body shape and weight-related stimuli among persons with eating disorders.

Conscious and preconscious processing of food, body weight and shape, and emotion-related words in women with anorexia nervosa

OBJECTIVE

The present study was conducted to extend prior research on attention toward food and body weight and shape-related stimuli in women with eating disorders.

METHOD

A modified Stroop color-naming task was completed by women with anorexia nervosa and by control females subdivided on a measure of dietary restraint. Eating disorder-relevant word categories included words connoting fatness, words connoting thinness, low caloric density food words, high caloric density food words, and neutral, control words. Valence effects were controlled for by including positively and negatively valenced emotion words. Stimuli were presented under both unmasked and masked conditions.

RESULTS

Using unmasked stimuli, patients with anorexia nervosa, but not unrestrained or restrained eaters, had delayed color-naming latencies for both thin and fat word categories and, to a lesser extent, for high caloric density food words. No differences were observed with masked stimuli.

DISCUSSION

Our findings suggest that both thinness and fatness are especially salient to women with anorexia. The lack of effects for emotion words suggests that these findings do not reflect a valence effect. We found no evidence for preconscious attentional biases in the masked condition.

Intensive nutritional counselling in bulimia nervosa: a role for supplementation with fluoxetine?

OBJECTIVE

The aims of the paper are to determine whether nutritional counselling is associated with an improvement in bulimic symptomatology, whether this improvement is maintained during post-treatment follow-up, and whether the addition of fluoxetine 3 x 20 mg/day confers additional benefit.

METHOD

Psychological, pharmacological and combined psychopharmacological treatments of bulimia nervosa were reviewed briefly. Sixty-seven patients referred to specialist eating disorder services who fulfilled strict diagnostic criteria were treated with intensive nutritional counselling and randomly assigned to either fluoxetine 3 x 20 mg/day or placebo. After a 1-week 'wash-out', active treatment was given over 8 weeks, followed by post-treatment interviews at 12 and 20 weeks.

RESULTS

Both groups of patients improved significantly during treatment. In some respects, the fluoxetine group did slightly better as demonstrated by the items 'restraint', 'weight concern' and 'shape concern' (p < 0.05 vs p < 0.0001) on the Eating Disorder Examination (EDE). Fluoxetine patients decreased their energy intake and lost a modest amount of weight. They went on to regain weight during the follow-up period, returning to levels higher than they were initially. These patients also appeared more likely to have a recurrence of symptoms, as shown by the fall in percentage of binge-free patients and by changes in the EDE.

CONCLUSION

Nutritional counselling is an effective means of treating bulimia nervosa, with improvement maintained up to 3 months follow-up. The addition of fluoxetine may confer some benefit during active treatment, but its discontinuation may contribute to a higher rate of recurrence of symptoms post treatment. Of course, this study cannot be extrapolated to the efficacy of fluoxetine when used as the only form of treatment in patients for whom intensive nutritional counselling or other structured psychological programs are not available.

The use of guardianship legislation for anorexia nervosa: a report of 15 cases

OBJECTIVE

This paper investigates compulsory treatment under guardianship legislation for 15 anorexia nervosa patients admitted to four eating disorders units in New South Wales (NSW), Australia, between 1991 and 1994.

METHODS

A retrospective follow-up was conducted. This involved an analysis of sociodemographic, clinical, eating and weight history, and Guardianship Order details obtained from medical records. This small sample was compared to a larger sample of anorexia nervosa patients admitted voluntarily to a specialised eating disorder unit in NSW. Further follow-up included a structured interview using the Morgan-Russell Assessment Outcome Schedule at least 1 year after admission for compulsory treatment.

RESULTS

For those treated involuntarily, a larger number came from metropolitan Sydney and a larger percentage were unemployed, were purgers and required specialist medical consultations. A significantly higher proportion came from higher socioeconomic groups, and the duration of stay in hospital while patients were under guardianship was significantly greater. A high degree of comorbidity was noted. There were similarities between those treated involuntarily and those treated voluntarily for the source of referral, marital status and Body Mass Index on admission and discharge. Only three patients accepted a follow-up interview using the Morgan-Russell Outcome Schedule. Two of them had made a good recovery.

CONCLUSIONS

It was noted that the guardianship sample comprised a more severely III group than anorexic patients treated voluntarily. The nature of guardianship legislation compared to mental health law was discussed and advice offered to clinicians contemplating and implementing compulsory treatment.

Chronic fatigue syndrome and dieting disorders: diagnosis and management problems

OBJECTIVE

This paper illustrates the importance of conducting an initial and ongoing psychiatric assessment of patients with chronic fatigue syndrome in order to diagnose dieting disorders. The diagnostic issues and management problems of three case vignettes, two with anorexia nervosa and one with bulimia nervosa, are described.

METHOD

The treatment response of dieting disordered patients is generally prolonged after a previous diagnosis of chronic fatigue syndrome has been made and the patient and family favour a disease diagnosis.

RESULTS

Several management problems arise and family members may also be reluctant to accept a dieting disorder diagnosis.

CONCLUSIONS

Early detection of dieting disorders by adequate screening and assessment is necessary so that a significant reduction in morbidity may occur.

Specific comorbidity between bulimia nervosa and personality disorders

OBJECTIVE

The present study investigates the comorbidity between bulimia nervosa (BN) and the entire range of American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, 3rd rev. ed. (DSM-III-R) personality disorders and controls for the presence of coexisting depression.

METHOD

The Personality Disorders Examination (PDE), a structured interview that encompasses all 13 (provisional) DSM-III-R personality disorders, was administered to three groups of subjects: depressed BN patients (n = 15), nondepressed BN patients (n = 15), and nonpsychiatric controls (n = 15). The BN patients were referrals to a dieting disorder unit affiliated with the University of Sydney. They all met DSM-III-R criteria and all had body mass indexes (BMIs) greater than 19. The nonpsychiatric control group were recruited from an undergraduate psychology course. All subjects were given the Bulimic Investigatory Test, Edinburgh (BITE), the Eating Disorders Inventory-2 (EDI-2), the Hamilton Depression Rating Scale (HDRS), and the PDE.

RESULTS

46.7% of depressed BN patients met the criteria for at least one Axis II diagnosis, as assessed by the PDE, and 33.3% of nondepressed BN patients received such a diagnosis, whereas only 6.7% of nonpsychiatric control subjects met this criterion (p < .05). The results of the present study provide support for an increased comorbidity between personality disorders and BN that cannot be attributed to the confounding influence of coexisting depression.

DISCUSSION

This finding enables the identification of subgroups of individuals with BN, enabling them to be compared and contrasted. The identification of differences between subgroups may provide information regarding prognosis and differential response to treatment, which could enable more appropriate treatment decisions to be made.

Event related response variability in schizophrenia: effect of intratrial target subsets

The response-variance-curve (RVC) method quantifies the variability of the individual epochs that constitute the average event related potential (ERP), providing complementary information to that offered by ERPs. Numerous studies have found that average ERP late components of an auditory "oddball" paradigm can differentiate schizophrenic patients from normal subjects. Our previous study of the RVC measure revealed significant differences between medicated and unmedicated schizophrenic patients in the maximum ERP variability from 190 to 240 ms. In the present study of unmedicated schizophrenic patients and normal control subjects, we examined the influence of intertarget intervals (generated by pseudorandom stimulus sequences in an auditory oddball paradigm) on the intratrial effects of ERP variability measured by the RVC. The ERPs of unmedicated schizophrenic patients were characterized by an instability in a latency window corresponding to the N200 component. The effect was particularly large at an intertarget interval of 7.8 s and was significantly reduced on either side of this intertarget interval.

Maximum variance of late component event related potentials (190-240 ms) in unmedicated schizophrenic patients

The averaging of individual late component event related potential (ERP) responses, particularly P300, has revealed significant differences between schizophrenic patients and normal subjects. However, the averaging process removes the variability of the individual epochs that constitute that average. The response-variance-curve (RVC) method quantifies the variability of the individual epochs and allows examinations of windows of maximum variance. In this study, we examine the complementary nature of the RVC method to the traditional averaging approach. The averaged N200 and P300 ERP components differed significantly between the schizophrenic and normal groups, but not between the unmedicated and medicated schizophrenic patients. The RVC measure, on the other hand, revealed systematic differences in variability, maximal between 190 and 240 ms, between the unmedicated and medicated schizophrenic patients. The RVC measure therefore provides a focused time frame in which to examine dysfunctions in information processing and macroscopic scale changes in brain function due to medication.

Defining subgroups of dieting disorder patients by means of the Eating Disorders Examination (EDE)

BACKGROUND

It is important to determine the optimal manner of categorising eating disorder patients so as to aid in the understanding of their specific psychopathological state.

METHOD

We compared subgroups of eating disorder patients divided according to different sets of factors, using a structured interview which elicits the specific psychopathological features of these illnesses. The patients, comprising 116 consecutive women admitted to two university-affiliated eating disorder clinics, were grouped according to DSM-III-R criteria, clinical presentation (purging, binge eating), nutritional status, and age.

RESULT

The clearest separation of groups was afforded by the clinical dimension of purging as opposed to not purging. This was superior to DSM-III-R criteria. Other systems, such as presence of binge eating, and various levels of nutritional status and of age, were clearly inferior.

CONCLUSION

The presence or absence of purging behaviour appears to offer the most heuristic means of categorising eating disorder patients with respect to their specific psychopathological state.

Eating disorder patients at a NSW teaching hospital: a comparison with state-wide data

The aim of the study was to present data which may be useful in deciding the type of services needed for eating disorder (ED) patients in New South Wales (NSW). The demographic and clinical characteristics of 155 patients consecutively admitted to a special ED unit at a major Sydney teaching hospital during the triennium 1989-1991 were documented and compared with relevant data from the State as a whole (709 admissions for ED to public facilities and 938 admissions for ED to private facilities during the same period). The findings are discussed in the light of information from overseas studies. Although a relatively large number of ED patients are admitted to hospitals in NSW, their short duration of stay suggests that many may receive inadequate treatment. The unit in the Department of Psychiatry at the Royal Prince Alfred Hospital (RPA), the largest public ED service in NSW, provides a special service for these patients. It is effective in bringing about nutritional restoration, with a duration of stay similar to those reported from centres overseas. Most referrals are tertiary, and there is a high prevalence of physical morbidity indicating a need for access to general medical facilities. Most serious physical complications occur in patients who can be identified by their chronicity and by the pattern of their behavioural disturbance. These various factors are considered in the formulation of recommendations for rationalizing the service.

Body composition in anorexia nervosa - changes with treatment, determinants and techniques

Body fat, total body water and totally body nitrogen were estimated twice before and after refeeding in 32 patients with anorexia nervosa. Body composition was estimated once in 29 normal controls using the techniques of anthropometry, impedance and IVNCA. The influence of weight gain and other variables, ie psychological status, biochemical parameters, exercise and dietary composition, on protein repletion was examined. Methods of assessment of body composition were compared. The results demonstrated that in anorexia nervosa patients, protein was more completely replenished than fat when patients had reached 85% of average body weight for height and age. Weight gain was the only determinant of protein gain. There was no correlation with psychological, biochemical or exercise status nor with dietary composition. Direct methods, ie deuterium dilution and IVNCA, were shown to be preferable in determination of body composition in anorexia nervosa.

Anorexia nervosa in an adolescent with early profound deafness

This paper reports a case of anorexia nervosa in a 15-year-old schoolgirl who had been profoundly deaf since birth. She was admitted to a specialized eating disorders unit following a dramatic reduction in her weight. Her deafness and limited communication skills posed significant problems with regard to her overall management on the unit. Her clinical presentation and difficulties in management are presented.

Diagnoses of eating or dieting disorders: what may we learn from past mistakes?

A brief history of a patient is given and an attempt is made to reconcile the clinical realities she presents with the various diagnostic criteria that have been proposed for eating disorders. Despite much deliberation and many formulations, no scheme fully encompasses her not-uncommon problem. Rather than tinker yet again with the criteria for the syndromes of anorexia and bulimia nervosa, or introduce yet another new condition such as binge eating disorder, the authors suggest a unitary approach to diagnosis. Emphasis should be placed on the preoccupation with weight loss, the illness should be conceptualized as a dieting disorder rather than an eating disorder, and patient status should be accorded only when the disturbance results in significant psychological or physical ill-effects. The term anorexia nervosa should be retained for such cases, and all anorexia nervosa patients should be categorized on three parameters, viz: their current state of nutrition; the presence or absence of significant purging behaviors; and whether or not they have binge eating episodes.

Psychosocial Outcome and Long-term Weight Loss after Gastric Restrictive Surgery for Morbid Obesity

Forty-five of 60 consecutive morbidly obese patients who had a vertical banded gastroplasty carried out by the one surgeon between 1982 and 1988 were assessed by questionnaire at long-term follow-up in 1993. Eighteen patients (40%) had maintained their BMI at close to the lowest achieved levels. Twenty-seven patients (60%) had had a significant rise in BMI, and 14 of these (31%) had gained weight to return close to or above their pre-surgery BMI levels. No reliable predictors of successful long-term weight loss were detected in the pre-operative data. Forty-eight patients (84%) were satisfied with their surgical treatment. Twenty patients (44%) reported improved social life after surgery. Twenty-one patients (46%) reported a similar social life and only four patients (9%) a worse social life. At follow up five patients (12%) reported emotional problems related to their weight loss surgery and two of this group had had psychiatric counseling for depression. Pre-operative psychiatric assessment appeared to have facilitated intervention by the psychiatrist with these patients. Gastric restrictive surgery, however, remains unpredictable in its long-term weight loss effect.

A study of the relation between eating disorder and death concern

The relationship between eating disorder and various components of death orientation (fear, anxiety, acceptance and concern) was examined, taking into account the level of depression in patient samples as well as elements of religiosity. The results were not able to support more than a very modest relationship between eating disorder and death orientation. Eating disorder patients could not be distinguished from other clinical controls, nor did anorexia nervosa patients differ from other eating disorder patients in this respect. Beck and Beck [20] depression scores were higher in the non eating disordered clinical sample than in the eating disorder group, and death concern was shown to be related to the severity of depression. Religiosity did not appear important when indices of religiosity were considered, but did emerge as an important factor in the "free information" provided by participants.

Excessive physical activity in dieting disorder patients: proposals for a supervised exercise program

A relationship between starvation and hyperactivity has been observed in animal models, in experiments with human subjects, and in dieting disorder patients. Since the earliest descriptions of anorexia nervosa, excessive physical activity has figured prominently as a symptom of the illness, yet little attention has been directed towards this phenomenon. The aims of this paper are to review the published literature, to report our experience of the role of physical overactivity in the clinical presentation of dieting disorders, to discuss its implications for treatment, and to propose a supervised exercise program by which overactivity may be addressed specifically in the treatment of these patients.

Protein repletion and treatment in anorexia nervosa

Body fat and total body nitrogen (TBN) were quantified before and after refeeding in 32 female anorexia nervosa patients and in 29 matched control subjects by using the techniques of anthropometry and in vivo neutron-capture analysis (IVNCA). Mean body weight of patients (mean body mass index; BMI, in kg/m2), 15.4 +/- 1.3, was 72.7% of that of control subjects, increasing to 89.8% of mean weight of control subjects after refeeding (mean BMI 19.0 +/- 1.2). Mean BMI of control subjects was 21.6 +/- 2.7. Compared with the control group, patients' nitrogen was initially depleted by 24.5%, increased by 18.4%, but remained 10.6% below control values (P < 0.001). Body fat was depleted by 58.4%, increased by 89.7%, but remained 21.8% below control values (P < 0.001). Thus, despite a greater initial depletion and subsequently a greater net gain, body fat remained relatively more depleted after treatment than did nitrogen and protein. Anorexia nervosa patients were shown to readily replenish protein during nutritional rehabilitation.

Oral and dental complications in dieting disorders

This study investigated the oral status and dental complications in patients with both anorexia and bulimia nervosa. Results revealed that prolonged periods of dietary restraint in anorexic patients did not result in changes to bacteria associated in dental caries. Furthermore, patients did not have lower decay rates or salivary flow but did have more acidic saliva. Moreover, both groups of patients revealed changes indicative of gingivitis and gingival recession but not necessarily of periodontitis when compared to control subjects.

Measuring the specific psychopathology of eating disorder patients

Cooper and Fairburn's Eating Disorder Examination (EDE) is a semi-structured interview designed to assess the specific psychopathology of eating disorder subjects. It was employed in a study of 116 Sydney patients for 2 purposes: first, to determine its usefulness in an Australian context; and second, to compare patients with anorexia nervosa, bulimia and atypical eating disorder. The instrument appears to be quite appropriate for studies in Australia. With respect to the second aim, the results emphasize the essential similarity in psychopathology between the three diagnostic groups. The relevance of this latter finding to the categorisation of eating disorders in the DSM-IV proposals is discussed.

Anorexia nervosa in males: a report of 12 cases

The demographic and clinical features of 12 male patients with anorexia nervosa were investigated by means of a retrospective analysis of their medical records. The clinical characteristics of the male patients were found to be remarkably similar to those reported for female patients and our findings concur with previously published literature. There appears however to be a greater tendency to exercise excessively. The importance of recognising anorexia nervosa in males is emphasized.

How well are 'cured' anorexia nervosa patients? An investigation of 16 weight-recovered anorexic patients

Eating behaviour, nutritional intake and psychopathology were examined in 16 weight-recovered anorexia nervosa patients. The Eating Disorders Examination (EDE) and a food diary were the main outcome measures, but body fat content and psychosocial adjustment were also assessed. Although body fat and overall psychosocial adjustment had returned to normal in most patients, 12 still had a restricted eating pattern with nutritional intake below 90% of their energy requirements. These results suggest that weight, menstruation, and psychosocial criteria are not sufficient to determine full recovery from anorexia nervosa, and that attention should be given also to measures of the specific behavioural and attitudinal disturbance.

Parental evaluation of treatment outcome and satisfaction with an inpatient program for eating disorders

This study is concerned with the service provided to adolescent patients with eating disorders admitted to a private hospital. The patients' parents were asked to evaluate the service. Parental satisfaction was assessed by means of a questionnaire devised for this purpose and comments were elicited as to how the service could be improved. Parents of a consecutive series of 56 patients were asked to complete the questionnaire 6 months after admission; 82% (N = 46) responded. Most parents were pleased with the service provided but nevertheless many made some criticisms (35%) or suggestions for improvement (37%). The parental responses were discussed with the staff involved in treatment, resulting in changes to the service.

Dreams of death: Von Weizsäcker's Dreams in so-called endogenic anorexia: a research note

Viktor Von Weizsäcker's paper "Dreams in so-called endogenic Magersucht (anorexia," first published in the Deutsche Medizinische Wochenschrift in 1937 (translation in M. Kaufman & M. Heiman [1964]. Evolution of psychosomatic concepts: Anorexia nervosa: A paradigm (pp. 181-197), New York: International Universities Press, has been described as a noteworthy and historically important contribution to the recognition of anorexia nervosa as a psychosomatic illness. Von Weizsäcker analyzed the dreams of patients he was treating for "endogenous anorexia" (magersucht). He claimed that in the bulimic phase his patients experienced nightmares dealing with themes of death, but that in the anorectic phases of restricted eating more pleasant dreams dealt with themes of blissful contentment. The authors draw current attention to his work as another early example of the treatment of the theme of death and death symbolism in the literature on eating disorders, and suggest some reappraisal of von Weizsäcker's interpretations of his own material.

Phenomenology and the history of psychiatry

Phenomenology is a word much abused in psychiatry. It has come to mean the objective description of the symptoms and signs of psychiatric illness, a synonym for clinical psychopathology as opposed to that other psychopathology which derives from psychoanalytic theory. Thus it is sometimes stated that the phenomenology of a condition is remarkably consistent although its psychopathology is varied. In truth, phenomenology is a technical term in psychiatry with a specific meaning quite distinct from and in a way opposite to that of objective psychopathology. The inappropriate use of the word is unfortunate not only for semantic reasons but also because there is a real danger that the concept to which it refers will be forgotten.

The Parental Bonding Instrument in adolescent patients with anorexia nervosa

The Parental Bonding Instrument (PBI) was administered to 54 adolescent patients with anorexia nervosa. Scores were compared with those of matched groups of normal and of nonanorectic adolescents referred for assessment to an adolescent psychiatric unit. Significant differences between the 3 groups were demonstrated with respect to care and protection dimensions. Overall scores of subjects in the anorectic group resembled those of normals rather than those of referred patients. Anorexia nervosa patients described their fathers and mothers as being more caring and their mothers as being less overprotective than did psychiatrically referred peers. The study raised questions concerning the use of the PBI in adolescents, in particular those with anorexia nervosa, and the role of the family in the aetiogenesis of this condition.

Clinical and microbiological investigations of anorexia nervosa

Several studies have examined the relationship between anorexia nervosa and oral status. However, none has used control subjects. Furthermore, none has examined bacteriological data in these subjects to determine whether dietary restrictions, particularly of carbohydrates, change the levels of Streptococcus mutans and Lactobacillus species. Fifteen female subjects recently hospitalized for anorexia were studied along with fifteen age- and sex-matched control subjects. The parameters examined included salivary pH and flow rate, levels of S. mutans and Lactobacillus spp., DMFT scores, facial and palatal plaque scores, periodontal pocketing, gingival recession and bleeding following gentle probing. Compared with control subjects, anorexics had significantly lower salivary pH (7.1 +/- 0.4 vs 7.6 +/- 0.3, p less than 0.01), more facial and lingual surfaces with plaque scores of 1 (facial plaque 38 per cent vs 18 per cent, p less than 0.01, lingual plaque 47 per cent vs 29 per cent, p less than 0.01), more surfaces with gingival recession (1 mm-7.9 per cent vs 1.8 per cent, p less than 0.001; 2 mm-1.7 per cent vs 0.2 per cent, p less than 0.001; greater than 2 mm-0.6 per cent vs 0.0 per cent, p less than 0.001), more surfaces with bleeding on probing (16.9 per cent vs 6.5 per cent, p less than 0.001) and fewer sextants with CPITN scores of 0 (1.9 +/- 1.5 vs 3.2 +/- 1.0, p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Hypophosphataemia, delirium and cardiac arrhythmia in anorexia nervosa

OBJECTIVE

To draw attention to the occurrence of hypophosphataemia in anorexia nervosa and to suggest that it may be a factor contributing to cardiac arrhythmia, a potentially fatal complication.

DESIGN

A retrospective study of patients under the consultant care of one of us. All were adolescent girls or young women aged 14 to 31.

CLINICAL COURSE

During the index admission, three became acutely hypophosphataemic while receiving saline and potassium intravenously to correct hypokalaemia. Four patients were subsequently treated with phosphate supplementation. Two patients died, and three recovered.

CONCLUSION

Hypophosphataemia in anorexia nervosa patients may play a role in the development of cardiac arrhythmia and delirium.

A comparison of nutritional management with stress management in the treatment of bulimia nervosa

In a comparison of nutritional management (NM) and stress management (SM) for treatment of bulimia nervosa, 55 female patients were randomly assigned to either treatment. Therapy consisted of 15 sessions in a group over three months, by the end of which, patients under both treatment conditions showed a significant reduction in the frequency of binge eating and vomiting and a significant improvement in various psychopathological features such as body dissatisfaction and depression. All improvements were maintained over 12-month follow-up NM produced a more rapid improvement in general eating behaviour, a faster reduction in binge frequency and a higher abstinence rate from binge eating. SM led to greater positive changes in certain psychopathological features such as feelings of ineffectiveness, interpersonal distrust and anxiety. NM should be regarded as a necessary first intervention in all bulimic patients. Further psychological therapy, such as SM, is indicated as well for some patients, depending on their specific psychological difficulties.

Death related themes in anorexia nervosa: a practical exploration

On the basis of an extensive literature review, Jackson and Davidson (1986) suggested that the theme of death may constitute an integral part of the psychodynamic aetiology of anorexia nervosa. This paper describes an attempt to explore this contention using a structured questionnaire in a group of adolescent patients to examine experiences, concepts of and attitudes concerning death. Comparison of the responses of this group with those of age matched school student controls and recovered patients revealed qualitative and quantitative differences which lent some support to the hypothesis. It is concluded that death related themes are of significance in the understanding and management of this illness.

To weigh or not to weigh? Frequency of weighing and rate of weight gain in patients with anorexia nervosa

The present study compares the rate of weight gain during refeeding in 15 anorectic patients who were weighed daily with that of 15 who were weighed three times per week. There was no significant difference between the two groups.

Distorting patient or distorting instrument? Body shape disturbance in patients with anorexia nervosa and bulimia

Three current techniques for estimating body size (Image Marking, Visual Size Estimation, and Distorting Video techniques) were compared. Anorexia nervosa and bulimic patients and normal control subjects were required to make size judgments of the way they 'knew' they looked, the way they 'felt' they looked, and of the width of an inanimate control object. Results from the three techniques were not the same, thus implying that research findings can no longer be cross-compared. Moreover, while all subjects were similar in the accuracy of their estimation of a control object, anorexia nervosa and bulimic patients overestimated their own body size significantly more than normal controls. This difference was even more marked when affective instructions were compared.

The course of tardive dyskinesia in patients on long-term neuroleptics

Results are presented of five consecutive annual examinations using the Abnormal Involuntary Movement Scale for 101 community-based chronic psychiatric patients. These 101 patients had a history of longer and more consistent neuroleptic treatment than the 231 patients who initially entered the study, so no conclusions about prevalence of TD can be drawn. At each examination two-thirds of this group showed signs of TD; however, only 45% were TD positive at most examinations and 24% were best described as having fluctuating TD status. Of those patients who were consistently TD positive, 82% showed no overall significant change in summed AIMS scores, 11% improved and 7% became worse.

Anorexia nervosa in a woman totally blind since birth

A 19-year-old woman, blind since birth, lost 26 kg over a 7-month period. This was achieved by restriction of food intake, excessive exercise, laxative abuse, and self-induced vomiting. Although the visual experience is often believed to be an integral component of body-shape perception and the overvaluation of thinness in contemporary society, it does not preclude the development of anorexia nervosa.

AIMS ratings--repeatability

In the present study, two raters, a psychologist and a nurse, each made five independent ratings of 30 different video-recorded patient-examinations. Having thus excluded patient fluctuation, individual-rater consistency and between-rater agreement over the 6 weeks of the study are examined. While between-rater agreement was apparently being maintained, mean AIMS scores steadily increased. In the hands of these raters, AIMS items 2 and 4 emerged as very reliable, while items 1, 6, and 7 showed high variability. Some patients appeared to be hard to rate. Differences between the study raters and the author JB highlight the issue: how reproducible is an AIMS rating?

Vegetarianism in anorexia nervosa? A review of 116 consecutive cases

A retrospective study was carried out of 116 consecutive patients with anorexia nervosa to ascertain the extent and nature of vegetarianism in this population. Sixty-three (54.3%) patients were found to be avoiding red meat. In only four (6.3%) of these did meat avoidance predate the onset of their anorexia nervosa. Of the remaining 59 patients (best termed pseudovegetarians), 25 (42.4%) patients continued to avoid red meat by the end of treatment. Pseudovegetarianism was associated with a longer duration of anorexia nervosa, a lower weight during the course of their illness, and living away from the parental home. The reintroduction of red meat into the diet was more likely if vegetarianism were of a short duration.
