Health status, activity limitations, work-related restrictions and level of disability among Canadians with mood and/or anxiety disorders. / État de santé, limitations d'activité, restrictions professionnelles et degré d'invalidité chez les Canadiens atteints d'un trouble de l'humeur ou d'anxiété.

INTRODUCTION: This study provides the first overview of the perceived general and mental health, activity limitations, work-related restrictions and level of disability, as well as factors associated with disability severity, among Canadian adults with mood and/or anxiety disorders, using a population-based household sample. METHODS: We used data from the 2014 Survey on Living with Chronic Diseases in Canada- Mood and Anxiety Disorders Component. The sample consists of Canadians aged 18 years and older with self-reported mood and/or anxiety disorders from the 10 provinces (n = 3361; response rate 68.9%). We conducted descriptive and multinomial multivariate logistic regression analyses. RESULTS: Among Canadian adults with mood and/or anxiety disorders, over one-quarter reported "fair/poor" general (25.3%) and mental (26.1%) health; more than one-third (36.4%) reported one or more activity limitations; half (50.3%) stated a job modification was required to continue working; and more than one-third (36.5%) had severe disability. Those with concurrent mood and anxiety disorders reported poorer outcomes: 56.4% had one or more activity limitations; 65.8% required a job modification and 49.6% were severely disabled. Upon adjusting for individual characteristics, those with mood and/or anxiety disorders who were older, who had a household income in the lowest or lower-middle adequacy quintile or who had concurrent disorders were more likely to have severe disability. CONCLUSION: Findings from this study affirm that mood and/or anxiety disorders, especially concurrent disorders, are associated with negative physical and mental health outcomes. Results support the role of public health policy and programs aimed at improving the lives of people living with these disorders, in particular those with concurrent disorders.

INTRODUCTION: Cette étude fournit, au moyen d'un échantillon de ménages fondé sur la population, le premier aperçu, chez des Canadiens adultes atteints de troubles de l'humeur ou d'anxiété, de leur état de santé globale et de santé mentale perçu, de leurs limitations fonctionnelles, de leurs restrictions professionnelles et de leur degré d'invalidité, ainsi que des facteurs associés à une invalidité grave. MÉTHODOLOGIE: Nous avons obtenu les données de l'Enquête sur les personnes ayant une maladie chronique au Canada ­ Composante des troubles de l'humeur et d'anxiété. L'échantillon est composé de Canadiens âgés de 18 ans et plus, atteints d'un trouble de l'humeur ou d'anxiété autodéclaré et habitant l'une des 10 provinces (n = 3 361; taux de réponse 68,9 %). Nous avons mené des analyses de régression logistiques multidimensionnelles multinomiales et descriptives. RÉSULTATS: Parmi les Canadiens adultes atteints d'un trouble de l'humeur ou d'anxiété, plus d'un quart ont rapporté un état de santé globale (25,3 %) et de santé mentale (26,1 %) « passable ou médiocre ¼, plus du tiers (36,4 %) ont mentionné avoir une ou plusieurs limitations fonctionnelles, la moitié (50,3 %) ont déclaré qu'une modification de leur emploi a été nécessaire pour continuer à travailler et plus du tiers (36,5 %) souffrait d'une invalidité grave. Les personnes avec troubles de l'humeur et d'anxiété concomitants ont mentionné de moins bons résultats : 56,4 % avaient une ou plusieurs limitations fonctionnelles, 65,8 % ont mentionné qu'une modification de leur emploi a été nécessaire et 49,6 % souffraient d'une invalidité grave. Après ajustement pour les caractéristiques individuelles, les personnes atteintes d'un trouble de l'humeur ou d'anxiété qui étaient plus âgées, dont le revenu familial était situé dans le quintile du plus faible revenu ou du revenu faible à moyen ou qui avaient des troubles concomitants étaient plus susceptibles d'avoir une invalidité grave. CONCLUSION: Les résultats de cette étude confirment que les troubles de l'humeur ou d'anxiété, surtout dans le cas de troubles concomitants, sont associés à des résultats en santé physique et mentale négatifs. Ces constats soutiennent les actions en politique et programmes de santé publique qui visent à améliorer la vie des personnes atteintes de ces troubles, surtout celles qui sont atteintes de troubles concomitants.

Stigma, negative attitudes and discrimination towards mental illness within the nursing profession: a review of the literature.

The aim of this paper was to review the existing literature pertaining to stigma, negative attitudes and discrimination towards mental illness, specifically as viewed through the lens of the nursing profession. The results of the literature review were synthesized and analysed, and the major themes drawn from this were found to correspond with Schulze's model identifying three positions that healthcare workers may assume in relation to stigma of mental illness: 'stigmatizers', 'stigmatized' and 'de-stigmatizers'. In this paper, the nursing profession is examined from the perspectives of the first two major themes: the 'stigmatizers' and 'stigmatized'. Their primary sub-themes are identified and discussed: (1) Nurses as 'the stigmatizers': (a) nurses' attitudes in general medical settings towards patients with psychiatric illness and (b) psychiatric nurses; (2) Nurses as 'the stigmatized': (a) nurses who have mental illness and (b) stigma within the profession against psychiatric nurses and/or psychiatry in general. The secondary and tertiary sub-themes are also identified and reviewed.

Sertraline treatment of generalized social phobia: a 20-week, double-blind, placebo-controlled study.

OBJECTIVE: The authors evaluated the efficacy, safety, and tolerability of sertraline, a selective serotonin reuptake inhibitor, in the treatment of generalized social phobia. METHOD: Adult outpatients with generalized social phobia (N=204) from 10 Canadian centers were randomly assigned to receive sertraline or placebo in a 2:1 ratio for a 20-week double-blind study following a 1-week, single-blind, placebo run-in. The initial dose of sertraline was 50 mg/day with increases of 50 mg/day every 3 weeks permitted after the fourth week of treatment (dosing was flexible up to a maximum of 200 mg/day). Primary efficacy assessments were the percentage of patients rated much or very much improved on the Clinical Global Impression (CGI) improvement item and the mean changes from baseline to study endpoint in total score on the social phobia subscale of the Marks Fear Questionnaire and total score on the Brief Social Phobia Scale. RESULTS: In intent-to-treat endpoint analyses of 203 of the patients, significantly more of the 134 patients given sertraline (N=71 [53%]) than of the 69 patients receiving placebo (N=20 [29%]) were considered responders according to their CGI improvement scores at the end of treatment. The mean reductions in the social phobia subscale of the Marks Fear Questionnaire and in the total score on the Brief Social Phobia Scale were 32.6% and 34.3% in the sertraline group and 10.8% and 18.6% in the placebo group, respectively. Analysis of covariance showed superiority of sertraline over placebo on all primary and secondary efficacy measures. Sertraline was well tolerated: 103 (76%) of the 135 sertraline-treated patients and 54 (78%) of the 69 placebo-treated patients completed the study. CONCLUSIONS: Sertraline is an effective treatment for patients with generalized social phobia.

Prevention of relapse in generalized social phobia: results of a 24-week study in responders to 20 weeks of sertraline treatment.

The aim of this study was to evaluate the efficacy, tolerability, and effects on quality of life of sertraline, a selective serotonin reuptake inhibitor, in the prevention of relapse of generalized social phobia. Fifty adult outpatients with generalized social phobia who were rated much or very much improved on the Clinical Global Impression Scale of Improvement (CGI-I) after 20 weeks of sertraline treatment (50-200 mg/day) were randomly assigned in a one-to-one ratio to either continue double-blind treatment with sertraline or immediately switch to placebo for another 24 weeks. The initial 20-week study was placebo-controlled, and 15 responders to placebo also continued to receive double-blind placebo treatment in the continuation study. Eighty-eight percent of patients in the sertraline-continuation group and only 40% of patients in the placebo-switch and placebo-responder groups completed the study. In intent-to-treat endpoint analyses, 1 (4%) of 25 patients in the sertraline-continuation group and 9 (36%) of 25 patients in the placebo-switch group had relapsed at study endpoint (chi2 = 8.0, Fisher exact test, p = 0.01). The relative risk (hazards ratio) for relapse associated with placebo-switch relative to sertraline-continuation treatment was 10.2 (95% confidence interval, 1.3-80.7). Mean CGI-Severity, Marks Fear Questionnaire (MFQ) Social Phobia subscale, and Duke Brief Social Phobia Scale (BSPS) total scores were reduced by 0.07, 0.34, and 1.86 in the Sertraline-Continuation group and increased by 0.88, 4.09, and 5.99 in the Placebo-Switch group (all F > 5.3, p < 0.03), respectively. CGI-Severity, MFQ Social Phobia subscale, and BSPS scores also increased in the Placebo-Responder group. Discontinuations because of lack of efficacy were 4% in the sertraline-continuation group, 28% in the placebo-switch group (chi2 = 5.36, Fisher exact test, p = 0.049), relative to sertraline, and 27% in the placebo-responder group. Sertraline was effective in preventing relapse of generalized social phobia. Future research should assess whether improvements may be maintained or further increased by longer periods of treatment or through the addition of cognitive-behavioral techniques.

Comparison of shoplifting behaviours in patients with eating disorders, psychiatric control subjects, and undergraduate control subjects.

Shoplifting behaviours were examined in an eating disorder group (EDG, n = 48), a psychiatric control group (PCG, n = 46), and an undergraduate control group (UCG, n = 82). They were examined in relation to self-esteem, depression, and eating disorder symptomatology. The 3 groups did not differ in overall history of shoplifting, but EDG women were more likely to have shoplifted in the past 6 months (current shoplifting) and to have shoplifted often than were women from the PCG or UCG. Across all 3 groups, current shoplifting was associated with low self-esteem, elevated depression, and purging behaviours at the time of the assessment. The implications of these findings with regard to the relationship between shoplifting and eating disorder symptomatology will be addressed.

Inhibited expression of negative emotions and interpersonal orientation in anorexia nervosa.

OBJECTIVE: This study examined inhibited expression of negative feelings and interpersonal orientation in women with anorexia nervosa. METHOD: Twenty-one women meeting DSM-IV criteria for anorexia nervosa were compared with 21 psychiatric and 21 normal control women matched on education. Two measures were used to assess inhibited expression of negative feelings and interpersonal orientation: the State-Trait Anger Expression Inventory assesses the suppression and expression of anger and the Silencing the Self Scale assesses four cognitive schemas involving the repression of needs and feelings to protect interpersonal relationships. RESULTS: Women with anorexia nervosa reported significantly higher scores on the four Silencing the Self schemas and on suppressed anger after controlling for age. These group differences were maintained for two of the cognitive schemas (Care and Silence) after controlling for depression, self-esteem, and global assessment of functioning. Inhibited expression of negative emotion and interpersonal orientation scores were also significantly related to cognitive and affective components of body image dissatisfaction and to trait and self-presentational dimensions of perfectionism. DISCUSSION: These findings are reviewed in the context of health psychology, as well as feminist and temperament theories. Implications for treatment are addressed.

Dimensional assessment of personality pathology in patients with eating disorders.

This study examined patients with eating disorders on personality pathology using a dimensional method. Female subjects who met DSM-IV diagnostic criteria for eating disorder (n = 136) were evaluated and compared to an age-controlled general population sample (n = 68). We assessed 18 features of personality disorder with the Dimensional Assessment of Personality Pathology - Basic Questionnaire (DAPP-BQ). Factor analysis and cluster analysis were used to derive three clusters of patients. A five-factor solution was obtained with limited intercorrelation between factors. Cluster analysis produced three clusters with the following characteristics: Cluster 1 members (constituting 49.3% of the sample and labelled 'rigid') had higher mean scores on factors denoting compulsivity and interpersonal difficulties; Cluster 2 (18.4% of the sample) showed highest scores in factors denoting psychopathy, neuroticism and impulsive features, and appeared to constitute a borderline psychopathology group; Cluster 3 (32.4% of the sample) was characterized by few differences in personality pathology in comparison to the normal population sample. Cluster membership was associated with DSM-IV diagnosis -- a large proportion of patients with anorexia nervosa were members of Cluster 1. An empirical classification of eating-disordered patients derived from dimensional assessment of personality pathology identified three groups with clinical relevance.

Chest pain in anorexia nervosa.

OBJECTIVE: To determine the incidence and characteristics of chest pain in patients with anorexia nervosa. METHOD: A cross-sectional survey of 54 patients. A pain history according to a diagnostic algorithm that was constructed from a Medline search (1966-1996) was used. RESULTS: Eighty-seven percent of patients had experienced chest pain. The most common diagnosis was idiopathic, occurring in 38% of participants. The incidence of typical and atypical angina was 11% and 9%, respectively. Increasing age, smoking history, and a family history of chest pain were more common in those with the atypical or typical angina. CONCLUSIONS: Chest pain is a common symptom in patients with eating disorders, and the incidence of typical and atypical angina is surprisingly high. All patients with eating disorders should be screened for chest pain and other risk factors for coronary heart disease.

Shape- and weight-based self-esteem and the eating disorders.

OBJECTIVES: To determine the psychometric properties of the Shape- and Weight-Based Self-Esteem (SAWBS) Inventory in women with eating disorders, and to compare SAWBS scores in women who have eating disorders with women from psychiatric and normal control groups. METHOD: Women with eating disorders (n = 48), women with other psychiatric disorders (n = 44), and undergraduate control women (n = 82) completed the SAWBS Inventory and measures of depression, self-esteem, and eating disorder symptomatology. Twenty women from the eating disorder group completed the SAWBS Inventory a second time 1 week later. RESULTS: Similar to previous work in undergraduate samples, SAWBS scores were stable over 1 week, and demonstrated concurrent and discriminant validity in women with eating disorders. In between-group comparisons, SAWBS scores were higher among women with eating disorders than in either control group, even after controlling for age, socioeconomic status, body mass index, and self-esteem. A differing relationship between depression and SAWBS emerged as a function of group; SAWBS scores differed significantly among depressed, but not nondepressed women from the three groups. CONCLUSION: The psychometric properties of the SAWBS Inventory were established in women with eating disorders. As expected, SAWBS scores were higher in women with eating disorders than in the control groups. Clinical implications of these findings are discussed.

Randomized trial of measures of body fat versus body weight in the treatment of anorexia nervosa.

OBJECTIVE: To determine whether treatment goals based on body weight or body fat assessed by anthropometrics caused a larger reduction in the Eating Disorder Examination (EDE) over 3 months during the treatment of anorexia nervosa (AN). METHODS: Randomized trial comparing the use of body weight versus measures of body fat by anthropometrics, with the EDE as the outcome measure. Of 23 patients enrolled, 11 subjects who met diagnostic criteria for AN (DSM-IV) and received outpatient treatment from the Eating Disorders clinic of a university teaching hospital completed the study. RESULTS: Comparison of the 2 methods by independent t-tests, verified by Mann-Whitney and Sign tests, suggests no difference (p = 0.33). Due to the small sample size, statistical significance could not be assured. A cross-sectional survey of 48 clinic users found the majority of patients preferred to be followed by skinfold measurements and felt they were more helpful than weight. DISCUSSION: Regardless of which measurement is used, if the clinic staff firmly believe that a method is more helpful and more useful, it is likely that the patients will find it acceptable.

Anorexia nervosa: refeeding and hypophosphatemia.

A case of anorexia nervosa (AN) is reported where heart failure occurred secondary to severe hypophosphatemia despite oral phosphate supplementation. We recommend starting patients with AN on oral phosphate when refeeding is begun, monitoring serum phosphate every 1 to 2 days for at least the first week of refeeding, and discontinuation of refeeding during phosphate supplementation should severe hypophosphatemia develop.

The reliability of bioelectrical impedance analysis for measuring changes in the body composition of patients with anorexia nervosa.

OBJECTIVE: To determine whether bioelectrical impedance analysis (BIA) is a valid measure of change in body fat in anorexia nervosa (AN) patients during refeeding, as compared to skinfold calipers (SF). METHODS: Prospective cohort study with measures of BIA and SF performed once a month for 3 months on patients meeting the DSM-III-R criteria for AN who received treatment from the Eating Disorders Clinic of a university teaching hospital as inpatients or outpatients. RESULTS: Twenty patients completed the study. Comparison of the two methods by the Pearson correlation coefficient showed a weak negative correlation of r = -.305. Analysis by a graphical method confirmed the poor agreement that exists between the two methods. DISCUSSION: The inability of BIA to detect changes in body composition due to altered hydration, and to accurately assess the distribution of water between intracellular and extracellular compartments, limits its clinical usefulness in AN. It appears that SF measurements are preferable to BIA as a measure of body fat change in patients with AN.

Seasonality of symptoms in anorexia and bulimia nervosa.

OBJECTIVE: Recent research has suggested that a large proportion of patients with bulimia nervosa have seasonal (winter) worsening of mood symptoms similar to seasonal affective disorder (SAD). The objectives of this study were to determine the specificity of this finding in anorexia and bulimia nervosa, and to further delineate the seasonal mood and eating patterns in bulimia nervosa. METHOD: A modified Seasonal Pattern Assessment Questionnaire (SPAQ) was administered to consecutive female patients assessed at an Eating Disorders Clinic with DSM-III-R diagnoses of bulimia nervosa (BN, N = 60) and anorexia nervosa (AN, N = 31), and to female nonclinical comparison subjects (NC, N = 50). RESULTS: The BN group had higher global seasonality scores and more presumptive diagnoses of SAD than the other two groups; the AN patients, whether they had the restricting or binge eating/purging subtype, did not differ from the NC subjects. Thirty-two percent of the identified seasonal BN patients did not have parallel worsening of mood and eating symptoms in the same season. DISCUSSION: These results suggest that seasonality of symptoms is specific to BN and that there may be separate mechanisms for the seasonality of mood and eating symptoms in some BN patients.

The relationship between stealing and eating disorders: a review.

The literature exploring stealing behavior in individuals with an eating disorder is reviewed. Although epidemiological data are lacking, clinical observations and preliminary studies suggest an association between stealing behavior and eating disorders. Stealing appears to be strongly associated with bulimic symptoms in patients with eating disorders, and the presence of stealing behavior may serve as a marker of eating-disorder severity. The apparent connection between the two problems is discussed, and nine putative explanatory factors are examined: starvation-induced mental dysfunction, effects of medications, affective spectrum disorder, personality disorder, psychodynamic features, dissociative phenomena, tension reduction, pseudopubertal impulsivity, and sociocultural influences. Various combinations of these factors may operate in any particular patient. One of the challenges to our current understanding is the scarcity of information regarding the prevalence and distribution of stealing behavior in the general population. Areas for future research are suggested and include epidemiological surveys to investigate the proposed connection between stealing and eating disorders, examination of the effects of legal intervention, systematic study of the treatment of stealing in patients with eating disorders, and longitudinal studies exploring prognostic implications of stealing behavior.

Olfactory identification ability in anorexia nervosa.

OBJECTIVE: The hypothesis tested was that patients with severe eating disorders would demonstrate olfactory identification deficits as a result of zinc deficiency or malnutrition. METHOD: The University of Pennsylvania Smell Identification Test (UPSIT) was administered to 27 hospitalized female patients with anorexia nervosa and 50 normal control female subjects. For a subgroup of patients, serum zinc levels and body mass indices were obtained at pre- and post-nutritional repletion phases. RESULTS: UPSIT scores for patients with eating disorders were equivalent to normal control subjects in spite of the fact that the patients were nutritionally compromised as determined by body mass index. Serum zinc levels were not significantly different at pre- and post-nutritional repletion. CONCLUSIONS: In contrast to patients with schizophrenia, patients with severe eating disorders have intact olfactory function. This finding suggests that transient metabolic or nutritional disturbances alone cannot account for previously reported olfactory deficits.

Evidence-based psychiatry.

OBJECTIVE: To apply the evidence-based medicine paradigm to the domain of psychiatric practice and to bring out the consequences for psychiatry of this approach in order to foster the emergence of an evidence-based psychiatry. METHODS: The basic assumptions of traditional and evidence-based paradigms, as delineated by the Evidence-Based Working Group, are used to structure an exploration of the evidence-based approach to psychiatry. Theoretical and practical issues are considered and an example of evidence-based decision making is given. RESULTS: An evidence-based approach to psychiatry is described as one that emphasizes the importance of systematic observation and the use of rules of evidence in hypothesis testing. It is suggested that psychiatrists using this approach will be in a position to provide superior patient care. DISCUSSION: The application of scientific method to psychiatric problems is discussed as the essence of an evidence-based approach. The common error of "scientism" is described. The authors identify advantages and limitations of an evidence-based approach to psychiatric practice and advocate a decision-making process that balances individualized clinical acumen (phronesis) and information derived from empirical study of groups of patients (techne).

Accuracy of subcutaneous fat measurement: comparison of skinfold calipers, ultrasound, and computed tomography.

OBJECTIVE: The purpose of this study was to compare skinfold caliper and ultrasound measurement of subcutaneous body fat at three abdominal sites with computed tomography, which is considered to be the gold standard. DESIGN: This was a cross-sectional study in which computed-tomography, ultrasound, and skinfold caliper measurements were made at three distinct abdominal sites. All body composition and anthropometric measurements were performed on each subject on one occasion. SUBJECTS: Twenty-two subjects were recruited (13 men and 9 women). Mean ages (+/- standard deviation) were 43 +/- 4 years for the women and 51 +/- 18 years for the men. All subjects had been previously scheduled for an abdominal or pelvic computed-tomography scan at the Department of Radiology, St Paul's Hospital, Vancouver, British Columbia, Canada, and participated in the study on a volunteer basis. MAIN OUTCOME MEASURES: A better agreement was found between the skinfold calipers and computed-tomography methods than between the ultrasound and computed-tomography method for the measurement of subcutaneous body fat. This was observed when the data were analyzed for both correlational agreement and for graphical interpretation. STATISTICAL ANALYSES PERFORMED: The relationships among skinfold, ultrasound, and computed-tomography measurements were analyzed by determining Pearson correlation coefficients. A graphical method described by Bland and Altman was also used to assess agreement among the three methods. RESULTS: Significant correlation coefficients were observed between skinfold calipers and computed tomography at all three abdominal sites (site 1, r = .60, P = .003; site 2, r = .70, P = .0001; site 3, r = .73, P = .0001). Ultrasound and computed-tomography methods only showed a significant correlation at site 3 (r = .54; P = .009). The graphical method revealed that the variation in the ultrasound measurements was much greater than that of the skinfold measurements when compared to computed-tomography values. APPLICATIONS/CONCLUSIONS: The results of this study indicated that relative agreement in the measurement of subcutaneous body fat between skinfold and computed-tomography measurements was superior to that exhibited between ultrasound and computed-tomography measurements. This finding enhances the potential use of skinfold calipers in the clinical setting, particularly in view of the fact that measurement of subcutaneous body fat at different body sites is becoming increasingly important for the characterization of risk of certain disease states.

Polyglandular autoimmune syndrome and anorexia nervosa.

The first case of polyglandular autoimmune syndrome (PAS) in a patient with anorexia nervosa is reported. The association of pernicious anemia with vitiligo and endocrine hypofunction (PAS) is reviewed. Eating disorder patients with B12 deficiency who have vitiligo or a history of endocrine hypofunction should have a Schilling test to exclude pernicious anemia.

A controlled study of light therapy for bulimia nervosa.

OBJECTIVE: Winter worsening of mood and eating symptoms, similar to that of seasonal affective disorder, has recently been reported in patients with bulimia nervosa. To assess the effectiveness of light therapy for treatment of bulimia nervosa, the authors conducted a study of light therapy during winter comparing an active (bright white light) condition to a control (dim red light) condition in bulimic patients who were not selected for a seasonal pattern of bulimia. METHOD: After a 2-week baseline assessment, 17 female patients with a DSM-III-R diagnosis of bulimia nervosa underwent early morning light treatment with 2 weeks of bright white light exposure (10,000 lux for 30 min/day) and 2 weeks of dim red light exposure (500 lux for 30 min/day) in a counterbalanced, crossover design. Outcome measures included daily binge/purge diaries, objective and subjective measures of mood, and the Eating Attitudes Test. Expectation of response for each condition was also assessed before treatment. RESULTS: Although pretreatment expectation ratings were similar for each condition, the bright white light condition was superior to the dim red light condition for all mood and eating outcome measures. Patients with "seasonal" bulimia (N = 7) had significantly greater improvement after the bright white light treatment than patients with nonseasonal bulimia (N = 10). No significant order effects were noted, nor differential effects for patients taking concurrent antidepressant medications (N = 4). CONCLUSIONS: These data suggest that bright white light therapy is an effective short-term treatment for both mood and eating disturbances associated with bulimia nervosa, although the therapeutic effect may be greater in those patients with a seasonal pattern.
