不良妊娠结局包括流产、死胎和低出生体重。来自热量和资源缺乏的压力在产生这些不良结果方面发挥了潜在的重要作用。经历这些不良结果而不是健康分娩的妇女和夫妇也遭受心理，身体，社会和经济成本。我们使用详细的生殖数据结合精细的气候数据来研究撒哈拉以南非洲妇女的怀孕结果，该地区为世界上一些最贫困的家庭提供了庇护。精细尺度的降水和温度数据使每次怀孕都能与相关的气候暴露相匹配。我们使用具有固定效应的线性概率模型研究气候和妊娠结局之间的联系，以尽量减少因地点，季节和年份而异的因素造成的混淆。我们分析了15个非洲国家23项调查中记录的65，000多例妊娠的回顾性妊娠数据。我们的研究结果表明，即使考虑到其他个人水平的特征，怀孕结果确实受到暴露于炎热天气的影响。这项研究提供了深入了解气候与妇女面临的主要不利健康结果之间的联系。通过这样做，这项研究扩展了对环境因素对生育结果影响的科学认识。
Poor pregnancy outcomes include miscarriages, stillbirths, and low birth weights. Stress from heat and lack of resources play a potentially important role in producing these poor outcomes. Women and couples who experience these poor outcomes rather than a healthy birth suffer psychological, physical, social, and financial costs as well. We use detailed reproductive data in combination with fine-scale climate data to examine pregnancy outcomes among women in sub-Saharan Africa, a region that shelters some of the poorest families in the world. Fine-scale precipitation and temperature data allow each pregnancy to be matched to the relevant climate exposures. We investigate the linkages between climate and pregnancy outcomes using linear probability models with fixed effects to minimize confounding due to factors that vary by location, season, and year. We analyze retrospective pregnancy data from more than 65,000 pregnancies recorded in 23 surveys across 15 African countries. Our results indicate that pregnancy outcomes are indeed impacted by exposure to hot days even after considering other individual-level characteristics. This research provides insight into the linkages between climate and a major adverse health outcome faced by women. In doing so, this research expands scientific understanding of the impact of environmental factors on fertility outcomes.
