Abstract：
BACKGROUND: This study aimed to evaluate the incidence and risk factors of adnexal torsion (AT) in the Korean population from 2009 to 2018 (10 years).
METHODS: We analyzed the 2009-2018 data obtained from the Health Insurance Review and Assessment Service National Inpatient Sample (HIRA-NIS) database. AT was identified by both diagnosis codes and surgery codes of adnexal surgery.
RESULTS: A total of 6,262,910 women were recorded in the database. The incidence of AT was 6 per 100,000 women (95% confidence interval (CI), 6-6). The incidence of AT tended to decrease with age after peaking in the late 20s to early 30s. In the weighted logistic regression analysis, women of childbearing age, especially in their 20s and 30s, had the highest AT incidence. Corpus luteal cyst (p < 0.001) and benign neoplasm (p < 0.001) increased the incidence of AT. Low socioeconomic status (SES), Charlson comorbidity index (CCI), and pregnancy were unrelated to AT.
CONCLUSIONS: The incidence of AT is 6 per 100,000 women and peaks in the 20s to early 30s.

摘要：
背景：这项研究旨在评估2009年至2018年（10年）韩国人口中附件扭转（AT）的发生率和危险因素。
方法：我们分析了从健康保险审查和评估服务国家住院患者样本（HIRA-NIS）数据库获得的2009-2018年数据。AT由附件手术的诊断代码和手术代码确定。
结果：数据库中记录了总共6,262,910名妇女。AT的发生率为每100,000名女性中6名(95%置信区间(CI)，6-6).在20年代末至30年代初达到峰值后，AT的发病率随着年龄的增长而下降。在加权逻辑回归分析中，育龄妇女，尤其是在20多岁和30多岁的时候，AT发病率最高。黄体囊肿（p<0.001）和良性肿瘤（p<0.001）增加了AT的发生率。低社会经济地位(SES)，Charlson合并症指数（CCI），妊娠与AT无关。
结论：AT的发病率为6/100,000女性，在20至30年代初达到峰值。
