Berengüí R, Castejón MA. Personality Traits and Risk of Eating Disorders in Men: A Cross-Sectional Study. Healthcare (Basel) 2023; 11:2910. [PMID: 37958054 PMCID: PMC10649439 DOI: 10.3390/healthcare11212910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2023] [Revised: 10/31/2023] [Accepted: 11/03/2023] [Indexed: 11/15/2023] Open
Abstract
Eating disorders (EDs) have been understudied and misunderstood in men. Among the relevant factors in the risk, onset, and maintenance of EDs, personality stands out. Therefore, the aim of the study was to analyze the relationships between personality traits and risk variables for the development of EDs in men. A total of 443 male university students (mean = 22.16 years) who completed the Spanish versions of the Eating Disorder Inventory-3 (EDI-3) and the NEO Five-Factor Inventory (NEO-FFI) participated. Correlation analyses were performed, and in order to determine the predictive role of personality traits on risk scales, a hierarchical multiple regression was performed. The results showed that neuroticism was positively associated with drive for thinness, being its main predictor variable. In bulimia, the main relationships were positively associated with neuroticism and negatively with conscientiousness. As for body dissatisfaction, the main predictor variables were neuroticism and, in a negative sense, extraversion and openness to experience. In conclusion, personality traits are related to the risk of developing EDs in male university students, with neuroticism being the main associated trait.

Relationships between personality traits and disordered eating among Chinese female exercisers: the role of symptoms of exercise dependence and obsessive-compulsiveness. J Eat Disord 2022; 10:169. [PMID: 36397179 PMCID: PMC9670462 DOI: 10.1186/s40337-022-00679-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Accepted: 10/25/2022] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Although numerous studies have examined associations between personality traits and eating disorders in females, few studies have been conducted on female exercisers. Given the high risk of disordered eating in female exercisers, this study investigated the associations between the Big Five personality traits and disordered eating in female exercisers, and further explored the potential mediators, namely exercise dependence symptoms, and obsessive-compulsive symptoms underlying this association. METHODS A total of 295 female exercisers aged between 18 to 67 years (M = 22.11, SD = 6.65) participated in this study. RESULTS Negative and statistically significant correlations between conscientiousness (r = - 0.17, p < 0.01), emotional stability (r = - 0.27, p < 0.001) and agreeableness (r = - 0.18, p < 0.01) and disordered eating were observed in our sample of female exercisers. The multiple mediation analyses revealed that exercise dependence symptoms and obsessive-compulsive symptoms mediate the relationship between conscientiousness (β = 0.016, CI = [0.003, 0.031]), emotional stability (β = -0.012, CI = [- 0.028, - 0.002]), and disordered eating in female exercisers, whereas obsessive-compulsive symptoms (β = - 0.041, CI = [- 0.088, - 0.001]) but not exercise dependence symptoms are a mediator of the relationship between agreeableness and disordered eating. CONCLUSIONS Our findings can be used to improve the screening procedures for eating disorders in female exercisers as they contribute to a better understanding of the psychological mechanisms that underlie the associations between the Big Five personality traits and disordered eating.

Abstract
Bulimia Nervosa (BN) is a serious eating disorder, which affects 0.8-2.9% of the young population. The etiology is unknown and biomarkers would support in understanding the pathophysiology of BN, and in identifying BN patients that may benefit from medical treatment. This systematic review aims to answer whether (a) BN deviate from healthy controls in terms of serotonin (5-HT) biomarkers in blood, and whether (b) blood-based 5-HT biomarkers could be used to tailor psychopharmacological treatment in BN. A literature search using PubMed, PsycINFO and Embase was done using the following search terms: "Bulimia Nervosa" AND "serotonin" AND "blood" OR "plasma" OR "serum". 32 studies were included in this systematic review. Several biomarkers and challenge tests were identified and all studies described an association with BN and dysregulation of the 5-HT system compared to healthy controls. Several studies pointed to an association also to borderline symptoms in BN. BN deviate from healthy controls in terms of 5-HT biomarkers in blood supporting an abnormal 5-HT system in BN. 5-HT biomarkers and associated methods could be used to tailor treatment in BN although as yet, most tests described are unpractical for bedside use.

Abstract
OBJECTIVE Associations of specific types of stress with increased food intake and subsequent weight gain have been demonstrated in animal models as well as in experimental and epidemiological studies on humans. This study explores the research question of to what extent potentially obesity-related factors determine perceived stress in individuals with obesity. METHODS N = 547 individuals with obesity participated in a cross-sectional study assessing perceived stress as the outcome variable and potential determinants of stress related to obesity. Based on the available evidence, a five factorial model of 'obesity-related obesogenic stressors' was hypothesized, including the dimensions, 'drive for thinness', 'impulse regulation', 'ineffectiveness', 'social insecurity', and 'body dissatisfaction'. The model was tested using multiple linear regression analyses. RESULTS The five factorial model of 'potentially obesity-related stressors' resulted in a total variance explanation of adjusted R² = 0.616 for males and adjusted R² = 0.595 for females for perceived stress. The relative variance contribution of the five included factors differed substantially for the two sexes. CONCLUSION The findings of this cross-sectional study support the hypothesized, potentially obesity-related factors: 'drive for thinness', 'impulse regulation', 'ineffectiveness', 'social insecurity', and 'body dissatisfaction' as relevant determinants of perceived stress in individuals with obesity.

Abstract
Background This study examined relationships between attachment style, eating disorders (EDs), personality variables and family functioning. Methods In our study, 253 women (M = 25.72 years, SD = 8.73) were grouped into one of four categories either according to self-reported ED diagnosis or by exceeding cut-offs for a clinical diagnosis on the Eating Disorder Examination Questionnaire (EDE-Q) or Short Evaluation of Eating Disorders (SEED): anorexia nervosa (AN), bulimia nervosa (BN), other eating disorder (O-ED), no eating disorder (Non-ED). The ED group (AN, BN, O-ED) included 106 women (M = 24.74 years, SD = 7.71), and the Non-ED group 147 women (M = 26.42 years, SD = 9.37). Approximately half of the ED group had a comorbid disorder (59.4 %), while the majority of the Non-ED group had no psychological disorder (89.1 %). Results Participants with an ED were significantly more often insecurely attached (Adult Attachment Scale; AAS), emotionally unstable, less extraverted (Big-Five-Test of Personality; B5T) and showed less positive family functioning (Experiences in Personal Social Systems Questionnaire; EXIS.pers). Results showed partial mediation for attachment and EDs through neuroticism, extraversion and family functioning. Discussion The study found further evidence for elevated problems with attachment, personality, and family experiences in individuals with EDs, while suggesting mechanisms that may link these constructs. Implications for research and practice were discussed. Conclusion This study supports findings that acknowledge the mediating role played by personality factors and family functioning in the relationship between attachment and EDs.

Abstract
Research on anorexia has tended to focus on individuals who are seeking treatment, leading to treatment models that are based on individuals already receiving help. Therefore, the purpose of this study was to explore personality differences between individuals seeking treatment and those not seeking treatment for anorexia. Participants were 148 women recruited from three online sources. They completed a personality measure derived from the five-factor model and the Eating Attitudes Test-26. Results indicated that individuals with anorexia who were not seeking treatment scored lower on Agreeableness and Conscientiousness than both individuals seeking treatment and a control group. Also, individuals with anorexia in general tended to score lower on Extraversion and higher on Neuroticism than individuals in a control group. These results suggest that being open about treatment options, increasing successes, motivation, and organization, and highlighting the seriousness of anorexia could be beneficial in getting individuals with anorexia to seek and continue in treatment.

Psychobiology of borderline personality traits related to subtypes of eating disorders: a study of platelet MAO activity. Psychiatry Res 2011; 190:287-90.

Abstract
Increased and decreased levers of platelet monoamine oxidase (MAO) activity have been reported in patients with eating disorders, indicating abnormalities of the serotonin turnover. However, whether these findings are related to eating disorders or are rather reflecting the pathophysiology of borderline personality traits in these patients is still unknown. Platelet MAO activity and comorbid personality disorders were investigated in 72 patients with different subtypes of eating disorders (ED) and in a group of 28 healthy controls. ED patients comprised the following subtypes: 25 anorexia nervosa (AN) restrictive, 14 AN binge eating-purging (AN b-p), 3 anorexia nervosa not otherwise specified (AN NOS) and 30 bulimia nervosa (BN). Personality disorders and traits were assessed with the Structured Interview for Personality Disorders (SCID-II), the Zanarini Rating Scale for Borderline Personality Disorder, and the Barrat Impulsiveness Scale. Platelet MAO activity was significantly lower in ED patients with comorbid borderline personality disorder (BPD) than in ED without Borderline personality disorder (BDP). Platelet MAO activity was significantly and inversely correlated with the number and severity of BPD clinical features. In the subsample of patients with binge eating-purging symptoms (AN b-p, AN NOS and BN), platelet MAO activity was significantly lower in binge-purge patients with comorbid BPD than in binge-purge patients without BPD. The whole group of eating disorders had a significantly reduced lever of platelet MAO activity compared with the control group. The results suggest that low platelet MAO activity might characterize eating disorders with comorbid borderline personality traits, reflecting greater serotonin dysfunction in these patients. The role of decreased platelet MAO as an endophenotype with specific clinical manifestations should be explored in future studies.

Abstract
OBJECTIVE To evaluate the incremental validity of a dimensional assessment of personality, after controlling for diagnostic category, in accounting for meaningful variation in eating disorder attitudes and behaviours and in current affective distress among a clinical sample of eating disordered women. METHODS 244 treatment seeking eating disordered women and 116 non-eating disordered women were assessed with the NEO five factor inventory (NEO-FFI), and with measures of eating disorder attitudes and of affective distress using a cross sectional design. RESULTS As predicted, differences were found between eating disordered and non-eating disordered women on several NEO-FFI scales, which provided a context for subsequent analyses. NEO-FFI scales accounted for meaningful variation in eating disordered attitudes and behaviours as well as in levels of current affective distress over and above DSM-IV diagnostic category. CONCLUSION A flexible approach to diagnosis, which includes personality dimensions along with a description of eating disorder symptoms, may result in a more inclusive and useful diagnostic scheme for treating women with eating disorders.

Abstract
OBJECTIVE A systematic analysis of data collected with the Eating Disorder Inventory (EDI) was made. METHOD A literature search identified 94 sources in which the mean values of the EDI or EDI-2 subscales were reported, comprising 310 samples differing by sex, age, diagnosis, language, ethnicity, or some other relevant attribute. The total number of respondents was 43,722, from 25 different countries, having used the EDI in one of the 16 languages (1-94). RESULTS The factorial structure of the aggregate means of the EDI subscales, for both clinical versus nonclinical and Western versus non-Western samples, was almost identical suggesting generalizability across languages and cultures. Non-Western participants scored higher than Western participants on virtually all EDI subscales, both in normal and eating-disordered samples. It was shown that age is a risk factor when someone is already diagnosed with an eating disorder but, in the general population, increasing age reduces the likelihood of being afflicted by eating disorders. DISCUSSION Symptoms of eating disorders are more pronounced in non-Western than in Western samples.
