The association between fear of childbirth (FOC) and subsequent birth rate is not well studied. The aim of this study is to evaluate the birth rate, and risk for second pregnancy ending in delivery among women with FOC compared to women without FOC in their first pregnancy.
Data from the National Medical Birth Register were used to evaluate the birth rate after the first pregnancy in women with FOC. Cox regression model was used to evaluate the risk for the second pregnancy ending in delivery in women with FOC compared to reference individuals without FOC. The results were interpreted with adjusted hazard ratios (aHRs) and 95% confidence intervals (CI).
In total, 375,619 women were included in this study. Of these, 9660 (2.6%) had FOC in the first pregnancy (exposed group), and 365,959 (97.4%) had no FOC (non-exposed group). In the exposed group, 3600 (37.3%) women had second pregnancy ending in delivery during the study period, and 206,347 (56.4%) had the second pregnancy ending in delivery in the non-exposed group. The risk for the second pregnancy ending in delivery was lower among women with FOC (aHR 0.61, CI 0.59-0.63).
FOC complicates pregnancy and delivery and is strongly associated with lower likelihood to get pregnant again. Therefore, more research should be focused on the optimal prevention of FOC using a standardized procedure of care and treatment for women with FOC.
分娩恐惧(FOC)与随后的出生率之间的关系尚未得到充分研究。本研究旨在评估与首次妊娠无 FOC 的女性相比,FOC 女性的出生率以及第二次妊娠分娩的风险。
本研究使用国家医疗生育登记处的数据评估 FOC 女性首次妊娠后的出生率。使用 Cox 回归模型评估 FOC 女性与参考无 FOC 个体相比,第二次妊娠分娩的风险。结果以调整后的危险比(aHR)和 95%置信区间(CI)表示。
共有 375619 名女性纳入本研究。其中,9660 名(2.6%)在首次妊娠时存在 FOC(暴露组),365959 名(97.4%)无 FOC(非暴露组)。在暴露组中,3600 名(37.3%)女性在研究期间第二次妊娠分娩,206347 名(56.4%)女性在非暴露组中第二次妊娠分娩。与非暴露组相比,FOC 女性第二次妊娠分娩的风险较低(aHR 0.61,CI 0.59-0.63)。
FOC 使妊娠和分娩复杂化,并且与再次怀孕的可能性降低密切相关。因此,应该更加关注使用针对 FOC 女性的标准化护理和治疗程序来预防 FOC。
