Abstract

OBJECTIVE

To determine whether previous cesarean delivery is an independent risk factor for ectopic pregnancy.

METHODS

We analyzed data collected between October 1988 and August 1990 from a case-control study of ectopic pregnancy among parous, black, non-Hispanic women, 18-44 years old, at a major metropolitan hospital in Georgia. Cases were 138 women with confirmed ectopic pregnancy; controls were 842 women either seeking abortion or delivering an infant. Unconditional logistic regression was used to estimate the relative risk while controlling for the effects of potential confounders selected a priori.

RESULTS

Adjusted for age, parity, marital status, history of pelvic inflammatory disease, infertility, douching, and smoking, the odds ratio was 0.6 (95% confidence interval 0.4-1.1), indicating no significant association.

CONCLUSION

We found no evidence of an increased risk of ectopic pregnancy related to previous cesarean delivery.

摘要

目的

确定既往剖宫产是否为异位妊娠的独立危险因素。

方法

我们分析了1988年10月至1990年8月间在佐治亚州一家大型都市医院对18 - 44岁已生育、黑人、非西班牙裔妇女进行的异位妊娠病例对照研究中收集的数据。病例为138例确诊异位妊娠的妇女；对照为842例寻求堕胎或分娩婴儿的妇女。在控制先验选择的潜在混杂因素影响的同时，使用无条件逻辑回归来估计相对风险。
