热浪可能令人惊地延长怀孕并降低早产风险,特别是在高风险怀孕中. 这挑战了关于妊娠期间热应激的假设.
科学领域:
- 环境健康 环境健康
- 生殖流行病学 生殖流行病学
- 围产儿医学 围产儿医学
背景情况:
- 环境热应激越来越被认为是影响母亲和胎儿健康的重要因素.
- 以前的研究经常表明,暴露于热量对怀孕结果的负面影响是一致的.
- 了解热浪对孕期持续时间的微妙影响对于公共卫生至关重要.
研究的目的:
- 为了研究热浪暴露与怀孕持续时间之间的关联.
- 为了确定与不同怀孕阶段的热浪暴露相关的分娩和早产风险.
- 为了探索热浪在怀孕期间与特定的孕产妇条件的潜在保护作用.
主要方法:
- 分析了波兰3170多起单独怀孕 (2013-2020) 的数据.
- 应用考克斯的比例危险模型,对违反比例危险假设进行调整,使用时间变化和分层建模.
- 包括灵敏度分析和模型诊断,以确保可靠性和有效性.
主要成果:
- 在暴露于热浪和延长妊娠时间之间观察到一致的关联.
- 在暴露于热浪的情况下发现早产风险降低,即使在妊娠晚期.
- 在低甲状腺症,糖尿病和晚年孕产妇的怀孕中,保护作用更为明显.
结论:
- 暴露于热浪可能不会均有害,可能会促进更长的怀孕和减少早产.
- 适度的环境压力因素可能会触发对胎儿发育有益的补偿生理反应.
- 这些发现需要重新评估产科护理和气候变化适应策略中的热暴露影响.
