在分娩前一周暴露于环境温度变化增加了心血管事件的风险. 较高的温度和较低的温度都与低风险人群的更高风险有关.
科学领域:
- 环境健康 环境健康
- 心血管健康 心血管健康
- 生殖健康 生殖健康
背景情况:
- 在分娩和分娩期间发生的心血管事件可能会带来重大风险.
- 环境温度是影响急性健康结果的潜在环境因素.
- 了解低风险人群中的这些风险对公共卫生至关重要.
研究的目的:
- 评估分娩期间心血管事件的急性风险.
- 调查分娩前一周环境温度与心血管事件之间的关联.
- 在低风险孕妇群体中分析这种关系.
主要方法:
- 采用了一个案例交叉设计,分析了191名患有心血管事件的妇女.
- 数据来源于尤尼斯·肯尼迪·施赖弗国家儿童健康和人类发展研究所连续怀孕研究 (犹他州,2002-2010年) 的数据.
- 条件后勤回归模型估计了温度暴露的几率比率 (OR) 和95%置信区间 (CI).
主要成果:
- 心血管事件包括心肌梗塞,中风,心力衰竭和心脏骤停.
- 在温暖的季节 (五月至十月) 中平均气温上升1°C与9%的风险增加有关 (95% CI:1.02,1.18).
- 寒冷季节 (十一月至四月) 平均气温下降1°C与6%的风险增加有关 (95%CI:1.00,1.13).
结论:
- 在分娩前一周环境温度的急性变化与心血管事件风险增加有关.
- 温暖季节温度的增加和寒冷季节温度的下降都会带来风险.
- 这些发现凸显了环境温度对周边心血管健康的影响.
