Self-reported assessment of female sexual function among Brazilian undergraduate healthcare students: a cross-sectional study (survey)

ABSTRACT BACKGROUND: The present study aimed to evaluate female sexual function among young undergraduate women. DESIGN AND SETTING: Cross-sectional survey conducted among Brazilian undergraduate students. METHODS: This study used online questionnaires to assess sociodemographic and health-related data and used the Brazilian version of the Female Sexual Function Index (FSFI) among female undergraduate students aged 18 to 25 years who were regularly enrolled in undergraduate healthcare courses. The FSFI is composed of 19 items that measure female sexual function over the last four weeks, in six domains: desire and subjective stimulation, sexual arousal, lubrication, orgasm, satisfaction and pain or discomfort. RESULTS: Among the 149 female undergraduate students evaluated, 43 (28.8%) presented sexual dysfunction (score < 26.55). Health conditions were not associated with female sexual dysfunction. Among the women with sexual dysfunction, all domains of the sexual response cycle were affected (P < 0.001). CONCLUSIONS: Sexual dysfunction was identified in at least a quarter of these young undergraduate women and it was not associated with gynecological problems, menstrual cycles, dysmenorrhea, contraceptive use or physical activity.

【研究背景与目的】本研究旨在评估青年女大学生的女性性功能水平。
【研究设计与实施场景】本研究为横断面调查，研究对象为巴西本科在读学生。
【研究方法】本研究通过线上问卷采集社会人口学特征与健康相关数据，并针对18至25岁、常规就读本科医学健康类专业的女大学生，采用巴西版女性性功能指数（Female Sexual Function Index, FSFI）开展评估。该指数共包含19个条目，用于评估受试者近4周内的女性性功能，涵盖6个维度：性欲与主观唤起、性唤起、润滑状态、性高潮体验、性满意度以及疼痛或不适感。
【研究结果】本次共评估149名女大学生，其中43人（28.8%）存在性功能障碍（得分＜26.55）。受试者的整体健康状况与女性性功能障碍无显著关联。在存在性功能障碍的女性中，性反应周期的所有维度均受到影响（P＜0.001）。
【研究结论】本研究队列中至少四分之一的青年女大学生存在性功能障碍，且该障碍与妇科疾病、月经周期、痛经、避孕措施使用及体力活动均无显著关联。
