To identify the risk factors for placenta previa in an Asian population.
This retrospective cohort study involved Taiwanese women delivered between July 1990 and December 2003 at Chang Gung Memorial Hospital, Taipei, Taiwan. Pregnancies complicated by multiple gestation and fetal anomalies were excluded.
There were 457 cases of placenta previa (1.2%) among the 37,702 pregnancies analyzed. Risk factors for placenta previa included a prior preterm birth (OR, 6.6; 95% confidence interval [CI], 4.1-10.6); technology-assisted conception (OR, 4.8; 95% CI, 2.9-7.8); smoking (OR, 3.3; 95% CI, 1.2-9.1) or working (OR, 3.8; 95% CI, 2.8-5.3) during pregnancy; maternal age of, or greater than 35 years (OR, 2.0 to 2.2; 95% CI, 1.3-3.7); and previous induced abortions (OR, 1.3-3.0; 95% CI, 1.1-7.1).
The risk factors for placenta previa were found to be the same for Asian women as those previously recorded for American and European women, but additional factors were detected.
确定亚洲人群前置胎盘的危险因素。
这项回顾性队列研究纳入了1990年7月至2003年12月在台湾台北长庚纪念医院分娩的台湾女性。排除多胎妊娠和胎儿畸形的妊娠。
在分析的37702例妊娠中，有457例前置胎盘（1.2%）。前置胎盘的危险因素包括既往早产（比值比[OR]，6.6；95%置信区间[CI]，4.1 - 10.6）；辅助生殖技术受孕（OR，4.8；95% CI，2.9 - 7.8）；孕期吸烟（OR，3.3；95% CI，1.2 - 9.1）或工作（OR，3.8；95% CI，2.8 - 5.3）；产妇年龄35岁及以上（OR，2.0至2.2；95% CI，1.3 - 3.7）；以及既往人工流产（OR，1.3 - 3.0；95% CI，1.1 - 7.1）。
发现亚洲女性前置胎盘的危险因素与先前记录的美国和欧洲女性相同，但还发现了其他因素。
