Orthorexia nervosa in the general population: A preliminary screening using a self-administered questionnaire (ORTO-15)

OBJECTIVE: Orthorexia, from the Greek words orthos (straight, proper) and orexis (appetite), is a newly conceptualized disorder characterized by distorted eating habits and cognitions concerning supposedly healthy nutrition. In this article we present preliminary results of a wider research aimed to investigate the diffusion of Orthorexia in the general population and to highlight its characteristics and particularly the relationship with Eating Disorder and Obsessive-Compulsive Disorder. METHOD: One-hundred and seventy seven adult subjects from the general population, were administered the ORTO-15 test, a selfadministered questionnaire specifically designed to assess orthorexic symptomatology; note that statistical analyses were repeated twice, referring to different diagnostic thresholds (40/35). RESULTS: Orthorexia had a 57.6% prevalence in our sample, using the 40-point threshold, with a female/male ratio 2:1; the figure was sensibly lower with the 35-point threshold (21%). CONCLUSION: The results of this study highlight the diffusion of Orthorexia which may constitute an important risk factor for mental and physical health, but also the opportunity of more specific diagnostic instruments, so to facilitate a thorough understanding of this disorder.

Relationship between bipolar illness and binge-eating disorders

In this study we describe the frequency of eating disorders (EDs) in a group of bipolar (BP) patients. We evaluated a sample of 51 outpatients, diagnosed as having BP I disorder on the basis of the Structured Clinical Interview for DSM-IV (SCID). Each of these subjects was administered the Binge Eating Disorder Clinical Interview (BEDCI) to determine the presence of binge eating disorder (BED) or bulimia nervosa (BN). Of the 51 BP patients, 14 (9 BED, 5 BN) met criteria for an ED. Most patients developed binge eating coincident with the first episode of BP disorder or after the onset of it. This was true for those who developed BED as well as BN, and involved both manic and depressive phases. All BN patients were women (5/5), and family history of binge eating was present in 80% of BN subjects, but only in 22.2% of BED and 29.7% of non-ED BP patients. We found a high frequency of concordance between BP illness and binge eating problems in our sample of BP patients. Given the temporal sequence of the mood disorder, which generally preceded the ED, we suggest a model in which the ED evolves due to modulation of emotions with food, as well as use of medications to treat BP disorder that disrupt hunger and satiety mechanisms. Given differences in gender distribution and family history, cultural and familial influences may also be significant in the minority of BP binge-eating patients who develop BN.

Shared psychopathology in obese subjects with and without binge-eating disorder.

OBJECTIVE To investigate obese people with/without binge-eating Disorder (BED) in terms of shared psychopathological features pertaining to spectrum of eating disorders. METHOD One-hundred obese adult patients with a BMI > 30 kg/m(2) referred to an Eating Disorder Unit and/or hospital weight-loss programs were administered the BED Clinical Interview, the Eating Disorder Inventory, and the Structured Clinical Interview for Anorexic-Bulimic Spectrum, Self-Report. RESULTS Twenty-seven subjects satisfied DSM-IV research criteria for current BED; compared to nonbingeing obese subjects, BED ones were characterized by greater weight-shape concerns influencing self-esteem (p = .05), overall impairment due to the overweight condition (p < .005), psychological distress leading to professional help (p < .001), dichotomous reasoning (p = .01) and secondary social phobia due to the overweight condition (p < .005). Compared to the other group, BED obese subjects scored higher at the following EDI subscales: bulimia (p < .0001), ineffectiveness (p < .01), interoceptive awareness and social insecurity (p < .05). CONCLUSION The results of this study highlight the role of cognitive mechanisms such as dichotomous reasoning and weight-shape concerns unduly influencing self-esteem as a hallmark of BED in obese patients, and the importance of investigating eating disorder psychopathology by adopting a dimensional perspective, rather than strictly focusing on categories when dealing with obese patients.

Caffeine consumption among eating disorder patients: Epidemiology, motivations, and potential of abuse

Objective: Aim of the study was to investigate caffeine use in different types of eating disorders (ED) patients either using a categorical approach [Diagnostic and Statistical Manual of Mental Disorders — Fourth Edition — Text Revision (DSM-IV-TR) diagnostic criteria] or a dimensional perspective. Method: Fifty-eight ED female patients [anorexia nervosa (AN), restricting and binge-eating/purging type, N=15; bulimia nervosa (BN) purging type/nonpurging type, N=26; binge eating disorder (BED), N=17] referred to an Eating Disorder Unit and 15 non-clinical controls were administered the Eating Disorder Inventory-2 (EDI-2), the Clinical Global Impression (CGI) and the Caffeine Use Test, an interview specifically developed to investigate caffeine intake. Statistical analyses were then repeated clustering patients according to the presence/absence of purging behaviors (purgers, N=22; non-purgers, N=19; BED, N=17). Results: Current and lifetime caffeine use, measured as mg/day, were similar comparing controls and ED patients as a whole. BN patients showed a significantly higher maximum lifetime caffeine intake (817.4±528,9 vs 325.0±294.6 mg/die, F=3.246, p<0.05); the same for purgers vs controls (p<0.05). Caffeine abuse was significantly more represented among patients vs controls (p<0.01), but similar among different patients’ groups. As for diagnoses according to DSM-IV-TR Substance Use modified for caffeine, no significant difference was found among the different groups, for either Dependence, Intoxication or Withdrawal. Most of patients and controls reported pleasure as the main motivation for caffeine use, followed by increased vigilance and attention and appetite suppression in AN and BN patients. Note that a shift in diagnosis in the course of the ED from non-purging to purging type was associated with an increase in caffeine current, lifetime and maximum lifetime intake (F=1.667 p<0.05), except for BED patients. Severity of the ED measured as CGI score or comorbidity did not affect caffeine intake in patients as a whole, but in the purging subgroup current caffeine use was increased in presence of an anxiety disorder (p<0.05), and decreased in presence of a mood disorder (p<0.01). Conclusions: Data from the present study are in agreement with previous evidence in literature that a high percentage of ED patients ordinarily use caffeine with an average intake similar to that of the general population, however with a kind of binge attitude. Among heavy drinkers, daily caffeine intake and alcohol/cigarettes use are associated supporting the link with the dimension of impulse disregulation. The substantial number of subjects from our sample satisfying research criteria for Dependence, together with increasing reports of caffeine intoxication, suggests the growing relevance of these issues that deserve further investigation.
