使用宫内节育器育龄妇女痛经危险因素Logistic回归分析

目的:探讨使用宫内节育器的育龄妇女痛经的主要危险因素,为预防及降低育龄妇女痛经的患病率提供依据。方法:观察应用宫内节育器的育龄妇女630例,采用结构式问卷进行访谈并行妇科体检及B超检查,记录痛经的发生状况及可能影响因素。以是否发生痛经Y作因变量,以一般情况、既往妇科疾病史、月经史、婚育史、避孕情况、妇科检查等X1～X22因素作自变量进行Logistic回归分析。结果:痛经的患病率为22.52%;经Logistic回归分析,妇科炎症X6、妊娠次数X7、人流次数X11、子宫位置X21共4个因素与痛经具有统计学关联(P<0.05),OR值分别为3.785、0.094、10.786和3.777。结论:人工流产次数多、曾患有妇科炎症,子宫为后位的育龄妇女更易发生痛经;妊娠次数增加,痛经发生的危险性降低。因此采用科学合理的避孕措施降低人流率、早期诊断治疗妇科炎症、产后保持乐观情绪早期活动恢复子宫正常位置等健康行为指导,利于预防和减少痛经的发生。

Logistic regression analysis of dysmenorrhea of fertile women using intrauterine device

Objective:To investigate the main risk factors of dysmenorrhea of fertile women using IUD and provide evidence for reducing the incidence of dysmenorrhea.Methods:By using structured questionnaires,630 women with IUD at childbearing age were interviewed,gynecological examination and B-ultrasonography were used.Occurrence of dysmenorrhea and its possible influence factors were recorded.Multivariate logistic regression analysis was conducted with y(whether a symptom of dysmenorrhea occurs) as dependent variable and X1~X22 as independent variable.Results:The morbidity of dysmenorrhea was 22.52%.Logistic regression analysis: association was observed among the 4 factors(P<0.05),gynecological inflammation,pregnancy number,artificial abortion number and uterine position,OR were 3.785,0.094,10.786 and 3.777,respectively.Conclusion:More number of artificial abortion,uterus retroposit and gynecological inflammation are more likely to lead to the occurrence of dysmenorrheal.The increasing number of pregnancy would reduce the risk of dysmenorrhea.Therefore the guidance of health behavior could reduce the risk of dysmenorrhea of fertile women.Scientific and reasonable contraceptive measures are done to reduce the abortion rate,early diagnosis and treatment of gynecological inflammation,and early activity inducing uterine to normal position.
