The relation between sexuality and obesity. The role of psychological factors in a sample of obese men undergoing bariatric surgery

Abstract Obesity produces a significant deterioration in general and sexual health. The aim of this cross-sectional study was to investigate the impact of obesity on sexuality, illustrating the psychological constructs that may play a significant role in determining sexual functioning and satisfaction. During the psychological assessment for bariatric surgery eligibility, 171 obese men filled out a socio-demographic questionnaire, the International Index of Erectile Function (IIEF), the 20 Item- Toronto Alexithymia Scale, the Symptom Checklist-90-Revised, the Body Uneasiness Test, and the Obesity-related Disability test. A series of hierarchical multiple regression analyses highlighted how obese men sexual desire (F(11,159) = 10.128, p < 0.001), erectile function (F(10,160) = 63.578, p < 0.001), orgasmic function (F(10,160) = 33.967, p < 0.001), intercourse satisfaction (F(7,163) = 159.752, p < 0.001), and general satisfaction (F(10,160) = 18.707, p < 0.001) were significantly associated with other IIEF sexual domains, difficulties in identifying feelings, psychopathological symptoms (such as depression and paranoid ideation), body image, and quality of life. Findings are useful for deepening understanding of obese male sexual response, and more generally, for analyzing the complex and multivariate relation between obesity and sexuality, supporting the need of a multidisciplinary approach to obesity care that includes professionals with specific training in sexology. Introduction Obesity and sexuality Obesity is a complex chronic disease, and it has increasingly become a major public health problem worldwide [1]. Obesity and overweight affect the 39% of world’s population [2] and are recognized as primary risk factors for early mortality and higher morbidity rates, such as cardiovascular problems, hypertension, type 2 diabetes, metabolic syndrome, hyperlipidemia, and obstructive sleep apnea [3–6].
