摘　　要：目的 探讨人工流产后再次意外妊娠的影响因素,为降低再次意外妊娠发生率提供参考依据。方法 选择2022年3—12月在宁夏地区公立医院妇科门诊因非意愿妊娠进行人工流产的2 560例20~35岁育龄女性进行回顾性分析。通过单因素和多因素logistic回归模型分析年龄、婚姻状况、学历、职业、流产方式、月经(经期/周期)、吸烟、饮酒等因素对人工流产后再次意外妊娠的影响。结果 宁夏地区人工流产后女性3个月内再次意外妊娠发生率为1.02%。单因素和多因素logistic回归分析均显示:职业(学生)是人工流产后再次意外妊娠的危险因素(P<0.05,β>0),经期正常是人工流产后再次意外妊娠的保护因素(P<0.05,β<0)。结论 宁夏地区进行的流产后关爱服务取得了一定效果,20~35岁育龄女性人工流产后再次意外妊娠发生率较低,高效避孕方法使用率增加。学生更易在人工流产后3个月内再次发生意外妊娠,经期正常有助于保护女性生殖健康。Objective To explore the influencing factors of subsequent unplanned pregnancy after induced abortion,provide a reference basis for reducing the incidence rate of subsequent unplanned pregnancy.Methods A retrospective analysis was performed on 2560 women of childbearing age aged 20-35 years old undergoing termination of pregnancy due to unplanned pregnancy in Gynecologic Clinic of Ningxia Public Hospitals from March to December in 2022.Univariate and multivariate logistic regression models were used to analyze the effects of age,marital status,educational level,occupation,abortion mode,menstruation(menstrual period/cycle),smoking,alcohol consumption,and other factors on subsequent unplanned pregnancy after induced abortion.Results The rate of subsequent unintended pregnancy within three months after induced abortion was 1.02%.Univariate and multivariate logistic regression analysis showed that occupation(student)was a risk factor for subsequent unintended pregnancy after induced abortion(P<0.05,β>0),and menstrual period(normal)was a protective factor for subsequent unintended pregnancy after induced abortion(P<0.05,β<0).Conclusion Post-abortion care service in Ningxia region has achieved certain results,and the rate of subsequent unintended pregnancy after induced abortion among women of childbearing age aged 20-35 years old is at a low level,and the use of high-efficiency contraceptive methods has increased.Students are more likely to have subsequent unwanted pregnancy within three months after induced abortion,and regular menstrual period can help protect maternal reproductive health.
