Objective. The aim of the study was to determine the prevalence of vaginal flatus and some related risk factors in Iranian women. Methods. After conducting a pilot study, a sample size of 1000 subjects of 18 to 80 years was determined; of those 58 were unable to cooperate for various reasons. Age, parity, marital status, birth history, body mass index, and the weight of the largest newborn were collected. After a full gynecologic examination looking for pelvic organ prolapse, patients were asked about vaginal flatus and the frequency and time of occurrence. The results were studied using the chi-square test and independent t-test considering an alpha error of less than 0.05. Results. The prevalence of vaginal flatus was mainly 20% in this study, but embarrassment was observed in 5.7% of these women. 4% in the group were with no history of sexual contact (virgin). Vaginal flatus mostly started after vaginal delivery (45%) or spontaneously (34%); however, it was also reported after cesarean section and other pelvic operations. The most common activity leading to vaginal flatus was intercourse (54%); however, the time which had resulted in more inconvenience for the patients was during physical activities (92%). BMI and age were significantly lower in the patients (P < 0.0001). The grade of prolapse was lower in the patients (P < 0.0001). Conclusion. Low age, low body mass index, and vaginal delivery can affect the incidence of a noisy vagina.
目的。本研究旨在确定伊朗女性阴道排气的患病率及一些相关危险因素。方法。在进行一项试点研究后，确定了1000名年龄在18至80岁之间的受试者作为样本；其中58人因各种原因无法配合。收集了年龄、产次、婚姻状况、生育史、体重指数以及最大新生儿体重等信息。在进行全面的妇科检查以寻找盆腔器官脱垂后，询问患者有关阴道排气的情况以及发生的频率和时间。使用卡方检验和独立t检验对结果进行研究，设定α错误小于0.05。结果。本研究中阴道排气的患病率主要为20%，但这些女性中有5.7%表示感到尴尬。该组中有4%的女性无性接触史（处女）。阴道排气大多在阴道分娩后开始（45%）或自发开始（34%）；然而，剖宫产和其他盆腔手术后也有报告。导致阴道排气最常见的活动是性交（54%）；然而，给患者带来更多不便的时间是在体育活动期间（92%）。患者的体重指数和年龄显著较低（P < 0.0001）。患者的脱垂程度较低（P < 0.0001）。结论。低年龄、低体重指数和阴道分娩会影响阴道排气的发生率。
