探讨哮喘史、哮喘严重程度与自然流产的关系。Pregnancy Study Online(PRESTO)是一项针对北美夫妇的孕前队列研究。在孕前期间,女性参与者报告了他们的医生诊断的哮喘史,首次诊断时的年龄以及在过去4周内使用哮喘药物的情况。哮喘的严重程度按受孕前的药物使用情况分类,从0级到3级,严重程度递增。使用随访问卷的数据确定妊娠和SAB。我们估计了风险比(HR)和95%置信区间(CI)。在6,325名怀孕的参与者中,19%经历了SAB,17%报告了哮喘史。哮喘史与SAB发生率之间无明显相关性(HR=0.98; 95%CI:0.84,1.14)。比较严重程度0、1和2-3与无哮喘的HR分别为0.82(95% CI:0.67,1.01)、1.20(95% CI:0.91,1.60)和1.31(95% CI:0.97,1.78)。在未使用生育治疗的女性中,2-3级严重程度与SAB相关(HR=1.39; 95% CI:1.02,1.89)。虽然哮喘诊断史与SAB没有实质性相关性,但严重哮喘(基于药物使用)与更大的SAB风险相关。
To evaluate the relationships among history of asthma, asthma severity, and spontaneous abortion (SAB). Pregnancy Study Online (PRESTO) is a preconception cohort study of North American couples. During the preconception period, female participants reported their history of physician-diagnosed asthma, age at first diagnosis, and use of asthma medications in the previous 4 weeks. Asthma severity was classified by medication use proximal to conception, from level 0 to 3 in increasing severity. Pregnancy and SAB were identified using data from follow-up questionnaires. We estimated hazard ratios (HRs) and 95% confidence intervals (CIs). Among 6,325 participants who conceived, 19% experienced SAB and 17% reported a history of asthma. There was no appreciable association between asthma history and SAB incidence (HR=0.98; 95% CI: 0.84, 1.14). HRs comparing severity levels 0, 1, and 2–3 with no asthma were 0.82 (95% CI: 0.67, 1.01), 1.20 (95% CI: 0.91, 1.60), and 1.31 (95% CI: 0.97, 1.78), respectively. Among women who conceived without the use of fertility treatment, level 2–3 severity was associated with SAB (HR=1.39; 95% CI: 1.02, 1.89). While history of asthma diagnosis was not materially associated with SAB, having severe asthma (based on medication use) was associated with greater SAB risk.
