To quantify the associations between asthma characteristics and the risk of preeclampsia.
In this case-control study, asthma history among 286 preeclampsia cases and 470 normotensive controls in Seattle was assessed by postpartum interview and medical record abstraction. OR and 95% CI were estimated using logistic regression. The sample size was adequate to detect unadjusted asthma history with ORs of > or =1.6 at a power of 80%.
After adjustment, women with a history of prepregnancy asthma diagnosis were not at increased preeclampsia risk (OR 0.94, 95% CI 0.58-1.52). Women experiencing asthma symptoms during pregnancy were more likely than pregnant nonasthmatics to have preeclampsia (OR 2.20, 95% CI 0.79-6.10). Those with long-term pre-pregnancy asthma and symptoms during pregnancy were at particularly increased risk (OR 9.09, 95% CI 1.02-81.6). Point estimates were generally higher after restriction to women withfull-term deliveries.
This analysis suggests that asthmatics, particularly those who are symptomatic during pregnancy, may be at higher risk of developing preeclampsia.
量化哮喘特征与子痫前期风险之间的关联。
在这项病例对照研究中，通过产后访谈和病历摘要评估了西雅图286例子痫前期病例和470例血压正常对照者的哮喘病史。使用逻辑回归估计比值比（OR）和95%置信区间（CI）。样本量足以检测未调整的哮喘病史，其OR值≥1.6，检验效能为80%。
调整后，有孕前哮喘诊断史的女性子痫前期风险并未增加（OR 0.94，95%CI 0.58 - 1.52）。孕期出现哮喘症状的女性比未患哮喘的孕妇更易患子痫前期（OR 2.20，95%CI 0.79 - 6.10）。那些孕前有长期哮喘且孕期有症状的女性风险尤其增加（OR 9.09，95%CI 1.02 - 81.6）。在限制为足月分娩的女性后，点估计值通常更高。
该分析表明，哮喘患者，尤其是孕期有症状的患者，患子痫前期的风险可能更高。
