STUDY OBJECTIVE Teenage pregnancies and associated induced abortions represent an important public health issue. The aim of this study was to investigate the prevalence, the time trends, and associated factors of teenage induced abortions in Greece. DESIGN A cross-sectional study was conducted between 2018 and 2019. SETTING Third Academic Department of Obstetrics and Gynecology of the Aristotle University of Thessaloniki. PARTICIPANTS All pregnant women who underwent a second trimester anomaly scan were eligible for the study. INTERVENTIONS AND MAIN OUTCOME MEASURES Epidemiological characteristics were recorded and 5 age groups were created. Trends in the rates of teenage induced abortions were analyzed and we compared several parameters between women with and without history of abortions. RESULTS Overall, 3370 women were eligible and agreed to participate in the study. The prevalence of women who reported a history of at least 1 abortion at 15-19 years was 9.7% (n = 328/3370). The abortion rates across the 5 age groups were: 20-24: 7.5%; 25-29: 8.4%; 30-34: 8.2%; 35-39: 12%; and 40 years and older: 13.9%. Moreover, a history of 1 or more teenage abortions was more common in multiparous women (58.2% vs 46.5%; P < .001; odds ratio, 1.605; 95% confidence interval, 1.274-2.022) and in current smokers (27.4% vs 11%; P < .001; odds ratio, 3.066; 95% confidence interval, 2.346-4.008). CONCLUSION A significant decline in the teenage induced abortion rates was identified in the study population. A history of teenage induced abortion was associated with smoking and multiparity. More efforts are needed to provide appropriate education on effective contraception and family planning.

希腊人工流产的趋势：横断面研究。

研究目的少女怀孕及相关的人工流产是一个重要的公共卫生问题。这项研究的目的是调查希腊青少年人工流产的患病率，时间趋势和相关因素。设计在2018年至2019年之间进行了横断面研究。设在塞萨洛尼基亚里士多德大学妇产科的第三学术系。研究对象所有接受了中期妊娠异常扫描的孕妇均符合研究条件。干预措施和主要观察指标记录流行病学特征，并建立5个年龄组。分析了青少年人工流产率的趋势，我们比较了有无流产史的妇女之间的几个参数。结果总体而言，3370名妇女符合条件并同意参加研究。报告在15-19岁至少有过一次流产史的女性患病率为9.7％（n = 328/3370）。5个年龄组的流产率分别为：20-24：7.5％；25-29：8.4％；30-34：8.2％；35-39：12％；40岁及以上：13.9％。此外，多胎女性中有1次或更多少女流产的病史更为普遍（58.2％比46.5％； P <.001；比值比为1.605； 95％置信区间为1.274-2.022）和当前吸烟者（27.4％比11％； P <0.001；优势比为3.066； 95％置信区间为2.346-4.008）。结论在研究人群中发现青少年人工流产率显着下降。青少年人工流产史与吸烟和多胎性有关。
