Physical performance measures in screening for reduced lean body mass in adult females with obesity.

BACKGROUND & AIMS: Little is known about the reduction of lean body mass (LBM) in obesity, or how to identify it in standard clinical settings. We therefore aimed to assess the prevalence of low LBM in adult females with obesity, and to identify the reliability of simple tools for its screening in this population. METHODS AND RESULTS: Dual-energy X-ray absorptiometry (DXA) body composition assessment was used to categorise 147 female participants with obesity as with or without low LBM, according to the new definition that takes into account both appendicular lean mass (ALM) and body mass index (BMI)-ALM/BMI <0.512. Participants were also administered the six-minute walking test, handgrip-strength test and 4-metre gait-speed test. Of the sample of 147 participants, 93 (63.3%) met the criteria for reduced LBM. Stepwise multivariate logistic regression analysis showed that the six-minute walking test was the only independent test associated with low LBM (OR = 0.992, 95%CI 0.987-0.998). Receiver operating characteristic (ROC) curve analysis found that the discriminating cut-off points of the tests considered were 470 m, 3.30 s (gait speed = 1.2 m/sec) and 23.5 kg respectively; the 4-metre gait-speed test seems to provide the best balance of sensitivity and specificity, and the greatest discriminatory power at 90% sensitivity. CONCLUSIONS: Treatment-seeking adult females with obesity display a great prevalence of reduced LBM. The six-minute walking test was the only independent test associated with low LBM, but the 4-metre gait-speed test seems to be the most accurate functional test for screening for this condition in that population.

Bone metabolism in patients with anorexia nervosa and amenorrhoea.

PURPOSE: Aim of this study is focusing on bone metabolism in AN patients with amenorrhoea and related estrogen deficiency effects. METHODS: AN patients were compared both with healthy females and with postmenopausal women (reference model for estrogen deficiency). The study sample included 81 females with AN. Laboratory tests [25-OH vitamin D, bone turnover markers, intact parathyroid hormone, sclerostin (SOST) and dickkopf-related protein (DKK1)] and dual energy X-ray absorptiometry (DXA) were taken into account. RESULTS: AN patients had higher levels of C-terminal telopeptide of type I collagen (CTX) than both control groups. AN adolescents had CTX higher than AN young adults. In postmenopausal women, intact N-propeptide of type I collagen was higher if compared with each other group. In AN groups, Dickkopf-related protein 1 was significantly lower than the two control groups. No differences were found in sclerostin except in adolescents. In AN adolescents, DXA values at femoral sites were higher than in AN young adults and a positive correlation was found with body weight (p < 0.01) and with fat mass evaluated using DXA (p < 0.01). CONCLUSIONS: AN women with amenorrhoea have an increased bone resorption like postmenopausal women but bone formation is depressed. The consequent remodeling uncoupling is considerably more severe than that occurring after menopause.

Body fat and menstrual resumption in adult females with anorexia nervosa: a 1-year longitudinal study.

BACKGROUND: The variables predicting the resumption of menses in anorexia nervosa (AN) after weight restoration have not yet been fully established. We therefore aimed to investigate the association between several clinical parameters at inpatient discharge and the resumption of menses at 1-year follow-up in weight-restored adults with AN. METHODS: Demographic, anthropometric, body composition and eating disorder features were assessed in 54 adult females with AN who had restored normal body weight [body mass index (BMI) ≥ 18.5 kg m(-) ²] at the end of specialist inpatient treatment. These variables were compared between participants who had resumed menses and those who were still amenorrheic 1 year after inpatient discharge. RESULTS: At 1-year follow-up, 35.2% of patients had resumed menstruation. No significant association was found between the resumption of menses and either age, duration of illness or BMI at inpatient admission, nor for BMI, global Eating Disorder Examination score or trunk fat percentage at inpatient discharge. Only total body fat percentage at inpatient discharge was significantly higher in patients who resumed menstruation, as confirmed by combined logistic regression analysis (odds ratio = 1.14, 95% confidence interval = 1.001-1.303, P = 0.049). CONCLUSIONS: A higher total body fat percentage at inpatient discharge is associated with the resumption of menses at 1-year follow-up in weight-restored adult females with AN.

Responses of peripheral endocannabinoids and endocannabinoid-related compounds to hedonic eating in obesity.

PURPOSE: Hedonic eating occurs independently from homeostatic needs prompting the ingestion of pleasurable foods that are typically rich in fat, sugar and/or salt content. In normal weight healthy subjects, we found that before hedonic eating, plasma levels of 2-arachidonoylglycerol (2-AG) were higher than before nonhedonic eating, and although they progressively decreased after food ingestion in both eating conditions, they were significantly higher in hedonic eating. Plasma levels of anandamide (AEA), oleoylethanolamide (OEA) and palmitoylethanolamide (PEA), instead, progressively decreased in both eating conditions without significant differences. In this study, we investigated the responses of AEA, 2-AG, OEA and PEA to hedonic eating in obese individuals. METHODS: Peripheral levels of AEA, 2-AG, OEA and PEA were measured in 14 obese patients after eating favourite (hedonic eating) and non-favourite (nonhedonic eating) foods in conditions of no homeostatic needs. RESULTS: Plasma levels of 2-AG increased after eating the favourite food, whereas they decreased after eating the non-favourite food, with the production of the endocannabinoid being significantly enhanced in hedonic eating. Plasma levels of AEA decreased progressively in nonhedonic eating, whereas they showed a decrease after the exposure to the favourite food followed by a return to baseline values after eating it. No significant differences emerged in plasma OEA and PEA responses to favourite and non-favourite food. CONCLUSION: Present findings compared with those obtained in our previously studied normal weight healthy subjects suggest deranged responses of endocannabinoids to food-related reward in obesity.

Body mass index, body fat and risk factor of relapse in anorexia nervosa.

BACKGROUND/OBJECTIVES: Preliminary studies have reported an association between poor long-term outcome and lower total body fat percentage in weight-restored inpatients treated for anorexia nervosa (AN). A possible link between poor long-term outcome and higher trunk fat percentage has also been hypothesized. The aim was to assess the association between percentage and distribution of body fat at inpatient discharge and the maintenance of normal weight at 1-year follow-up in a sample of weight-restored females with AN. SUBJECTS/METHODS: Fifty-four short-term weight-restored (body mass index (BMI; in kg/m(2)) ⩾18.5) adult females with AN treated in a specialist inpatient unit underwent dual-energy X-ray absorptiometry to determine total body fat and trunk fat percentages. Patients were contacted regularly following discharge, and at the end of the year clinical outcome was dichotomized as either 'full, good or fair' (a group that includes individuals with a BMI ⩾18.5 kg/m(2)) or 'poor' (BMI<18.5 kg/m(2)), using the modified Morgan-Russell criteria. RESULTS: No significant differences were found between 'full, good or fair' and 'poor' outcome groups in either total body fat or trunk fat percentages. Only lower BMI at inpatient discharge was associated with poor clinical outcome in the year following inpatient treatment. CONCLUSIONS: In short-term weight-restored adult females with AN, BMI, but not body fat percentage or distribution, at inpatient discharge is associated with long-term normal weight maintenance.

Personality, attrition and weight loss in treatment seeking women with obesity.

Studies on small samples or in single units applying specific treatment programmes found an association between some personality traits and attrition and weight loss in individuals treated for obesity. We aimed to investigate whether pre-treatment personality traits were associated with weight loss outcomes in the general population of women with obesity. Attrition and weight loss outcomes after 12 months were measured in 634 women with obesity (mean age, 48; body mass index (BMI), 37.8 kg m(-2)) seeking treatment at eight Italian medical centres, applying different medical/cognitive behavioural programmes. Personality traits were assessed with the Temperament and Character Inventory (TCI), eating disorder features with the Binge Eating Scale (BES) and Night Eating Questionnaire (NEQ). Within the 12-month observation period, 32.3% of cases were lost to follow-up. After adjustment for demographic confounders and the severity of eating disorders, no TCI personality traits were significantly associated with attrition, while low scores of the novelty seeking temperament scale remained significantly associated with weight loss ≥ 10% (odds ratio, 0.983; 95% confidence interval, 0.975-0.992). Additional adjustment for education and job did not change the results. We conclude that personality does not systematically influence attrition in women with obesity enrolled into weight loss programmes in the community, whereas an association is maintained between novelty seeking and weight loss outcome. Studies adapting obesity interventions on the basis of individual novelty seeking scores might be warranted to maximize the results on body weight.

Physical fitness before and after weight restoration in anorexia nervosa.

AIM: The aims of this paper were: 1) to evaluate the feasibility of test for evaluating physical fitness (PF) in patients with anorexia nervosa (AN); 2) to investigate the effects of nutritional rehabilitation in this population of patients; and 3) to compare their level of fitness scores (at baseline and after weight restoration) with an age-matched healthy control group. METHODS: PF was assessed with an adapted version of the Eurofit Physical Fitness Test Battery (EPFTB) administered to 37 consecutive female AN patients, at baseline and after weight restoration, and to 57 healthy age-matched females. RESULTS: The inpatient treatment, based on cognitive behavior therapy, was associated with a significant improvement in BMI (from 14.5±1.5 to 18.8±1.1, P<0.001) and in 5 out of 6 EPFTB tests (P<0.05) in the AN group. However, both in pre and post, AN patients showed significant lower EPFTB than the control group (all P<0.001) with the exception of the Sit-Up score. CONCLUSION: Results indicated that PF is lower in AN patients than in controls both at baseline and after weight restoration. Future studies should evaluate if the inclusion of an individualized health-enhancing physical activity program might improve the restoration of physical fitness.

Validation of the Italian version of the Functioning Assessment Short Test (FAST) for bipolar disorder.

Aim. The Functioning Assessment Short Test (FAST) is a useful instrument for the assessment of overall functioning of people with bipolar disorder, showing good psychometric properties. The aim of this study is to validate the Italian version of FAST. Methods. Translation and back-translation of the original FAST Spanish version were performed. Participants with bipolar disorder (n = 132) and healthy controls (n = 132) completed the FAST as a part of an assessment package including the Montgomery-Asberg Depression Rating Scale and the Young Mania Rating Scale. Internal consistency, inter-rater reliability, construct and discriminant validity were assessed. Results. The FAST Italian version showed good internal consistency, inter-rater reliability and discriminant validity. The cut-off discriminating patients from controls was 15, with a sensitivity of 0.79 and a specificity of 0.80. Principal component analysis with oblique rotation showed factor loadings consistent with the a priori structure of the instrument. Conclusions. This study confirmed the psychometric properties of FAST and extended its generalization and validity to the Italian population.

Role of translocator protein (18 kDa) in adult separation anxiety and attachment style in patients with depression.

BACKGROUND AND OBJECTIVES: A role for the protein that mediates the rate-limiting step of steroidogenesis, the 18 kDa Translocator Protein (TSPO), has been suggested in the pathophysiology of Adult Separation Anxiety Disorder (ASAD). It has been shown that ASAD patients have 1) low TSPO expression levels and 2) a high frequency of the allele that substitutes Ala with Thr at position 147 of TSPO. The Thr147 ASAD-associated allele has been recently related with a low pregnenolone production. The aim of the present work was to evaluate the relationship between TSPO expression levels and Ala147Thr single nucleotide polymorphism (SNP), which are the two TSPO biological parameters that we have previously examined separately. A further aim was to confirm the genetic association of Ala147Thr SNP with ASAD in an extended case-control sample and to investigate whether this SNP was related to an anxious attachment style that is thought to be connected to ASAD. METHODS: TSPO expression levels were compared among patients with ASAD (n=26), without ASAD (n=26) and control samples (n=10) stratified into the two genotype groups: those with the Ala147 genotype (named "normal pregnenolone production") and those with the Thr147 genotype (named "reduced pregnenolone production"). The case-control genetic study included patients with (n=87) or without (n=101) ASAD and 236 controls. In the patient group, the association between the Ala147Thr SNP and an anxious attachment style was analysed by stepwise logistic regression analysis. RESULTS: The genotype with the lowest TSPO expression levels was the "normal pregnenolone production" genotype in the ASAD group. The genetic Ala147Thr SNP confirmed an excess of the Thr147 allele in ASAD patients. Stepwise logistic regression analysis did not show an association with an anxious attachment style. CONCLUSIONS: ASAD individuals who expressed normal TSPO levels exhibited the "reduced pregnenolone production" genotype. In contrast, the ASAD individuals with the "normal pregnenolone production" genotype expressed low TSPO levels. It is possible that low TSPO expression levels could compromise normal pregnenolone production. Such evidence may have therapeutic implications because it has been documented that drugs targeting TSPO increased pregnenolone production and have anxiolytic effects.

Weight loss and clinical characteristics of young adults patients seeking treatment at medical centers: data from the QUOVADIS Study.

OBJECTIVE: To compare clinical characteristics, attrition, weight loss, and psychological changes of obese young adults and obese adults seeking treatment. MATERIALS AND METHODS: 1530 individuals seeking treatment in 18 Italian medical centers were evaluated. 382 cases (25%) were classified as young adults (age≤35 years), 1148 (75%) as adults (>35 years). Psychological distress, binge eating, body uneasiness, and attitude towards eating were evaluated, at baseline and after a 12-month weight-loss program, together with BMI changes. Weight-loss expectations and primary motivation for seeking treatment were also recorded. RESULTS: At baseline, young adults reported significantly higher BMI at age 20, weight loss expectations and body uneasiness scores than adults. A significantly higher percentage of young adults also reported improving appearance as primary reason for seeking treatment. The attrition rate was significantly larger in young adults. Among completers, the mean percent weight loss at 12 months and improvement of psychosocial variables were significantly higher in young adults than in adults. By intention to treat, BMI changes were no longer significant between groups. DISCUSSION: Obese young adults lose more weight and considerably improve psychological distress, but show a higher attrition rate after 12 months of continuous care in a real world medical setting.

Predictors of response among patients with panic disorder treated with medications in a naturalistic follow-up: the role of adult separation anxiety.

BACKGROUND: Efficacy of treatments for panic disorder is well established, but not all patients respond. Adult separation anxiety has been found to predict poorer response to CBT, but its effect on response to medication has not been previously explored. STUDY AIM: The aim of this study is to investigate if panic-agoraphobic spectrum factors, including 'separation anxiety' factor predict treatment outcome in patients with panic disorder. STUDY SAMPLE: Participants who met criteria for PD (n=57) completed baseline assessment and 12 months follow-up. Patients were administered the Panic Agoraphobic Spectrum Self-Report (PAS-SR, Lifetime and Last-Month Versions), and the Panic Disorder Severity Scale (PDSS). We examined patients who met the following criteria at baseline: 1) PDSS total score>7; 2) no current Axis I comorbidity with major depression; 3) no lifetime or current bipolar disorder. All patients were treated with evidence-based psychopharmacological treatment for panic disorder during the 12-month observation period. RESULTS: Twenty eight patients (48.1%) achieved remission during the follow-up period. In a logistic regression model, controlling for baseline severity, gender and age, only the last-month PAS-SR 'separation anxiety' factor was associated with a lower likelihood of remission. CONCLUSIONS: Signs and symptoms of separation anxiety in adulthood, as assessed with the PAS-SR Last Month version, are predictors of poor treatment outcome in patients with PD. We submit that the assessment of panic-agoraphobic spectrum features, including adult separation anxiety, should become routine of clinical assessment of patients with PD. It is likely that a better psychopathological characterization of patients may inform treatment selection, and result in better treatment outcome.

The CBCL 1.5-5 and the identification of preschoolers with autism in Italy.

AIMS: To study the potential use of child behaviour checklist (CBCL) 1.5-5 scales for the early identification of preschoolers at risk of autism. METHODS: CBCL scores of three groups of preschoolers were compared: (1) an experimental group of 101 preschoolers with autism spectrum disorder (ASD); (2) a control group of 95 preschoolers with other psychiatric disorders (OPD); (3) a control group of 117 preschoolers with typical development (TD). One-way analysis of variance (ANOVA), logistic regression with odds ratio (OR) and receiver operating characteristic (ROC) analyses were performed. RESULTS: ANOVA revealed that ASD and OPD had significantly higher scores in almost all CBCL scales than TD. ASD presented significantly higher scores than OPD on Withdrawn, Attention Problems and Pervasive Developmental Problems (PDP) scales. Logistic regression analysis demonstrated that these same CBCL scales have validity in predicting the presence of an ASD towards both TD and OPD. ROC analysis indicated high sensitivity and specificity for PDP (0.85 and 0.90) and Withdrawn (0.89 and 0.92) scales when ASD is compared to TD. Specificity (0.60 for PDP and 0.65 for Withdrawn) decreases when comparing ASD and OPD CONCLUSIONS: The PDP and Withdrawn scales have a good predictive validity so that they could be proposed as a first-level tool to identify preschoolers at risk of autism in primary care settings. Problems regarding the lower specificity when comparing ASD v. OPD are discussed.

Treatment-emergent suicidal ideation during 4 months of acute management of unipolar major depression with SSRI pharmacotherapy or interpersonal psychotherapy in a randomized clinical trial.

BACKGROUND: To date, few randomized controlled trials (RCTs) of major depression have examined suicidal ideation as an outcome measure. Our aim is to determine the incidence of treatment-emergent suicidal ideation (ESI) and behaviors during the acute phase of treatment with an SSRI antidepressant or interpersonal psychotherapy (IPT) in patients with unipolar major depression. METHODS: In a two-site RCT, 291 adult outpatients with nonpsychotic major depression and a Hamilton Depression Rating Scale (HDRS) score ≥15 were randomly allocated to IPT or SSRI. Participants who did not remit with monotherapy received augmentation with the other treatment. ESI was defined as a post-baseline HDRS suicidality item score ≥2 or a post-baseline Quick Inventory of Depressive Symptomatology (QIDS) score ≥2 in patients with a baseline score ≤1. RESULTS: Of the 231 participants who had no suicidal ideation at baseline, 32 (13.8%) subsequently exhibited ESI on at least one post-baseline visit. Time to suicidal ideation was significantly longer in patients allocated to SSRI compared to those allocated to IPT (HR = 2.21, 95% CI 1.04-4.66, P = .038), even after controlling for treatment augmentation, benzodiazepine use, and comorbidity with anxiety disorders. Worsening of suicidal ideation occurred in 7/60 patients who had suicidal ideation at baseline. In the large majority of cases, suicidal ideation was successfully managed with the study protocol. CONCLUSIONS: In the context of careful monitoring and frequent contact, selective serotonin reuptake inhibitor (SSRI) was associated with a lower risk of ESI than IPT and both SSRI and IPT appeared to be safe treatments for patients with past suicide attempts, none of whom exhibited ESI during the study.

Does psychomotor retardation define a clinically relevant phenotype of unipolar depression?

BACKGROUND: The recognition and assessment of psychomotor retardation may have implications for better definition of the clinical phenotypes of depression. The aim of this study was to assess the clinical correlates of psychomotor retardation endorsed at any time during the patients' lifetime (LPR). METHODS: The study sample included 291 patients with non-psychotic major depressive disorder (MDD) participating in the clinical trial, "Depression: The Search for Treatment-Relevant Phenotypes." Psychomotor retardation was measured using a factor derived from the Mood Spectrum Self-Report (MOODS-SR) assessment. Using a pre-defined cut-off score on the lifetime psychomotor retardation (LPR) factor of the MOODS-SR, participants were classified into high and low scorers. Logistic regression analysis was used to evaluate the relationship between LPR and subthreshold bipolarity. RESULTS: Compared to low scorers, participants with high scores on the LPR factor had greater severity of depression and more bipolarity indicators. CONCLUSIONS: The MOODS-SR appears to be helpful to identify clinical phenotypes of unipolar depression and to highlight the usefulness of a lifetime approach to the assessment of psychopathology in the characterisation of patients with unipolar depression.

Predictors and moderators of time to remission of major depression with interpersonal psychotherapy and SSRI pharmacotherapy.

BACKGROUND: Although many studies suggest that, on average, depression-specific psychotherapy and antidepressant pharmacotherapy are efficacious, we know relatively little about which patients are more likely to respond to one versus the other. We sought to determine whether measures of spectrum psychopathology are useful in deciding which patients with unipolar depression should receive pharmacotherapy versus depression-specific psychotherapy. METHOD: A total of 318 adult out-patients with major depression were randomly assigned to escitalopram pharmacotherapy or interpersonal psychotherapy (IPT) at academic medical centers at Pittsburgh, Pennsylvania and Pisa, Italy. Our main focus was on predictors and moderators of time to remission on monotherapy at 12 weeks. RESULTS: Participants with higher scores on the need for medical reassurance factor of the Panic-Agoraphobic Spectrum Self-Report (PAS-SR) had more rapid remission with IPT and those with lower scores on the psychomotor activation factor of the Mood Spectrum Self-Report (MOODS-SR) experienced more rapid remission with selective serotonin reuptake inhibitor (SSRI) pharmacotherapy. Non-specific predictors of longer time to remission with monotherapy included several panic spectrum and mood spectrum factors and the Social Phobia Spectrum (SHY) total score. Higher baseline scores on the 17- and 25-item Hamilton Depression Rating Scales (HAMD-17 and HAMD-25) and the Work and Social Adjustment Scale (WSAS) also predicted a longer time to remission, whereas being married predicted a shorter time to remission. CONCLUSIONS: This exploratory study identified several non-specific predictors but few moderators of psychotherapy versus pharmacotherapy outcome. It offers useful indicators of the characteristics of patients that are generally difficult to treat, but only limited guidance as to who benefits from IPT versus SSRI pharmacotherapy.

Effects of cognitive-behavioral therapy on Eating Disorders: neurotransmitter secretory response to treatment.

The effects of cognitive-behavioral therapy (CBT) on central dopamine (DA), noradrenaline (NE) and serotonin (5-HT) secretion were studied in a group of 50 female inpatients, of which 14 suffered from anorexia nervosa restricted type (AN-R), 14 from anorexia nervosa bingeing-purging type (AN-BP), and 22 from bulimia nervosa (BN). The aim of the study was to see whether or not CBT modifies the secretion of central DA (blood homovanillic acid=HVA), NE (blood 3-methoxy-4-hydroxy-phenylglycol=MHPG) and the 5-HT transporter (as evaluated by the platelet paroxetine binding=[(3)H]-Par-binding), if the physical and psychological effects of CBT correlate with changes of the neurotransmitter secretion; and if the biological effects of CBT are linked to specific psychopathological aspect of the disorders. The treatment lasted 20 weeks. Body-mass Index, bingeing and purging, specific AN-BN psychopathological (EDE 12-OD), depression (Beck Inventory), anxiety (STAY Form-Y-1), impulsiveness (Barratt Impulsiveness Scale), self-esteem (Rosenberg Self-Biochemical Scale) and temperament (Temperament and Character Inventory, Cloninger Scale) were assessed at baseline and at the end of the treatment. CBT significantly improved the psychophysical aspects of the diseases. HVA and MHPG concentrations did not change. The [(3)H]-Par-binding parameters, the maximum binding capacity (B(max)) and dissociation constant (K(d)) values did not change in either AN-R or AN-BP patients, while the [(3)H]-Par B(max) (and not the K(d)) increased significantly in BN patients. Correlations emerged between basal and final [(3)H]-Par B(max) values and psychopathological scores, but not between CBT-induced differences between basal and final values. Our data suggest that only in BN CBT may act through changes in 5-HT system function.

Frequency and clinical correlates of adult separation anxiety in a sample of 508 outpatients with mood and anxiety disorders.

OBJECTIVE: To evaluate the frequency and clinical correlates of adult separation anxiety disorder in a large cohort of patients with mood and anxiety disorders. METHOD: Overall, 508 outpatients with anxiety and mood disorders were assessed by the structured clinical interview for diagnostic and statistical manual (IV edition) axis I disorders for principal diagnosis and comorbidity and by other appropriate instruments for separation anxiety into adulthood or childhood. RESULTS: Overall, 105 subjects (20.7%) were assessed as having adult separation anxiety disorder without a history of childhood separation anxiety and 110 (21.7%) had adult separation anxiety disorder with a history of childhood separation anxiety. Adult separation anxiety was associated with severe role impairment in work and social relationships after controlling for potential confounding effect of anxiety comorbidity. CONCLUSION: Adult separation anxiety disorder is likely to be much more common in adults than previously recognized. Research is needed to better understand the relationships of this condition with other co-occurring affective disorders.

Night eating syndrome in class II-III obesity: metabolic and psychopathological features.

OBJECTIVE: To investigate the relationship of metabolic disorders and psychological features with the night eating syndrome (NES) in individuals with moderate-to-severe obesity. DESIGN: Cross-sectional observation. SUBJECTS: A total of 266 consecutive participants with class II-III obesity, entering an inpatient weight loss program. MEASUREMENTS: Participants who reported consuming either a large amount of their caloric intake after the evening meal (roughly self-assessed as > or =25% of daily calories) or the presence of nocturnal feeding at the Night Eating Questionnaire (NEQ) (N=49) were interviewed by the Night Eating Syndrome History and Inventory (NESHI). Assessment also included the clinical/biochemical parameters of the metabolic syndrome and several questionnaires of psychopathology. NES was diagnosed by NESHI criteria (evening hyperphagia (> or =25% of daily food intake after the evening meal) and/or waking at night to eat at least three times a week) in the last 3 months. RESULTS: Twenty-seven participants (10.1%) met NESHI criteria. Differences were not observed between participants with and without NES as to age, body mass index (BMI), prevalence of metabolic syndrome, Binge Eating Scale and Body Shape Questionnaire. NES participants had significantly higher scores of Beck Depression Inventory (BDI) and Impact of Weight on Quality of Life (IWQOL). Among NES cases, the BDI score was indicative of moderate depression in 18.5% of cases and of severe depression in 44.4%. Logistic regression analysis, adjusted for confounders, identified the BDI score as the only variable significantly associated with the diagnosis of NES. CONCLUSION: Diagnosing NES does not help identify obese individuals with specific medical complications, but indicates more severe psychological distress and depression.

The factor structure of lifetime depressive spectrum in patients with unipolar depression.

BACKGROUND: While previous attempts to elucidate the factor structure of depression tended to agree on a central focus on depressed mood, other factors were not replicated across studies. By examining data from a large number of items covering the range of depressive symptoms, the aim of the present study is to contribute to the identification of the structure of depression on a lifetime perspective. METHODS: The study sample consisted of 598 patients with unipolar depression who were administered the Mood Spectrum Self-Report (lifetime version) in Italian (N=415) or English (N=183). In addition to classical exploratory factor analysis using tetrachoric correlation coefficients, an IRT-based factor analysis approach was adopted to analyze the data on 74 items of the instrument that explore cognitive, mood and energy/activity features associated with depression. RESULTS: Six factors were identified, including 'Depressive Mood', 'Psychomotor Retardation', 'Suicidality', 'Drug/Illness related depression', 'Psychotic Features' and 'Neurovegetative Symptoms', accounting overall for 48.3% of the variance of items. LIMITATIONS: Clinical information on onset of depression and duration of illness is available only for 350 subjects. Therefore, differences between sites can only be partially accounted using available data. CONCLUSIONS: Our study confirms the central role of depressed mood, psychomotor retardation and suicidality and identifies the factors 'Drug/Illness related depression', 'Psychotic features' and the neurovegetative dysregulation not captured by the instruments most frequently used in previous studies. The identification of patients with specific profiles on multiple factors may be useful in achieving greater precision in neuroimaging studies and in informing treatment selection.
