The links between body weight and sexuality, notably sexual dysfunction (SD), are intricate and not yet fully understood. A more individual-focused evaluation of sexual difficulties, as recently provided by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), contributes to improve precision in SD diagnosis and has the potential to advance our knowledge on the association between body weight and SD.
To identify gender differences in sexual behaviors and SD among Portuguese men and women within different classes of body mass index (BMI); and to explore the association between BMI and SD by using the new DSM-5 criteria.
Face-to-face interviews followed by self-completed questionnaires of primary healthcare users in Portugal (n=323). Data on sociodemographic variables, BMI, sexual behaviors and SD were collected. DSM-5 criteria were used to assess sexual dysfunction. The International Index of Erectile Function (IIEF) and the Female Sexual Function Index (FSFI) for men and women, respectively, were used for comparison purposes.
Overweight and obese women reported less sexual partners, less satisfaction with sexual frequency and rated sexual life as less important. These differences were not found among men. Normal weight men and women had a higher score of IIEF and FSFI, respectively, than those overweight and obese. No significant effects of BMI scale on SD following DMS-5 were detected.
Women's sexual function is more impacted by BMI than men's. Individual-orientated approaches, as proposed in DSM-5, may allow a better understanding on the relation between body size and sexuality in both genders.
体重与性行为，尤其是性功能障碍（SD）之间的联系错综复杂，尚未完全明晰。《精神疾病诊断与统计手册》（第五版）（DSM - 5）最近提供了一种更关注个体的性功能障碍评估方法，有助于提高性功能障碍诊断的准确性，并有可能推进我们对体重与性功能障碍之间关联的认识。
确定葡萄牙不同体重指数（BMI）等级的男性和女性在性行为和性功能障碍方面的性别差异；并使用新的DSM - 5标准探索BMI与性功能障碍之间的关联。
对葡萄牙初级医疗保健使用者进行面对面访谈，随后让他们自行填写问卷（n = 323）。收集社会人口统计学变量、BMI、性行为和性功能障碍的数据。使用DSM - 5标准评估性功能障碍。分别使用国际勃起功能指数（IIEF）和女性性功能指数（FSFI）对男性和女性进行比较。
超重和肥胖女性报告的性伴侣较少，对性频率的满意度较低，且认为性生活不太重要。男性中未发现这些差异。正常体重的男性和女性的IIEF和FSFI得分分别高于超重和肥胖者。未检测到BMI量表对遵循DMS - 5的性功能障碍有显著影响。
女性的性功能比男性更容易受到BMI的影响。DSM - 5中提出的以个体为导向的方法可能有助于更好地理解两性中体型与性行为之间的关系。
