The impact of high ambient temperatures on delivery timing and gestational lengths

  title={The impact of high ambient temperatures on delivery timing and gestational lengths},
  author={Alan Barreca and Jessamyn Schaller},
  journal={Nature Climate Change},
Evidence suggests that heat exposure increases delivery risk for pregnant women. Acceleration of childbirth leads to shorter gestation, which has been linked to later health and cognitive outcomes. However, estimates of the aggregate gestational losses resulting from hot weather are lacking in the literature. Here, we use estimated shifts in daily county birth rates to quantify the gestational losses associated with heat in the United States from 1969 to 1988. We find that extreme heat causes… Expand

Temperature, climate change, and birth weight: evidence from Hungary
It is found that exposure to high temperatures during pregnancy decreases birth weight, but its impact on the probability of low birth weight is weaker; the second and third trimesters appear to be slightly more sensitive to temperature exposure than the first trimester. Expand
Post-conception heat exposure increases clinically unobserved pregnancy losses
Exposure to hot temperatures during the first few weeks after the conception week increases the clinically unobserved pregnancy loss rate, whereas exposure to colder temperatures seems to decrease it. Expand
What to Expect When It Gets Hotter: The Impacts of Prenatal Exposure to Extreme Heat on Maternal Health∗
We use temperature variation within narrowly-defined geographic and demographic cells to show that exposure to extreme heat during the first trimester increases the risk of maternal hospitalizationExpand
What to Expect When it Gets Hotter: The Impacts of Prenatal Exposure to Extreme Heat on Maternal and Infant Health
It is found that the heat-induced deterioration in maternal pregnancy health is larger for black than for white mothers, suggesting that projected increases in extreme heat over the next century may further exacerbate the black-white maternal health gap. Expand
Temperature, climate change, and human conception rates: evidence from Hungary
In this paper, we examine the relationship between temperature and human conception rates and project the impacts of climate change by the mid-twenty-first century. Using complete administrative dataExpand
An Evaluation of a Maternal Health and Extreme Heat Exposure Training
Assessments indicated that a training session can improve provider knowledge of maternal heat–health risks and can encourage providers to discuss heat risks with patients/clients and the development of similar trainings in other communities are encouraged. Expand
Independent and Combined Effects of Heatwaves and PM2.5 on Preterm Birth in Guangzhou, China: A Survival Analysis
Evidence that exposure to heatwaves during the final gestational week can independently trigger preterm birth is strengthened, which adds new evidence to the current understanding of combined effects of air pollution and meteorological variables on adverse birth outcomes. Expand
Temperature , climate change , and fertility
  • 2021
This chapter reviews the empirical literature on the impacts of temperature and climate change on human pregnancies. The focus is on the quasi-experimental studies that use panel data, apply a fixedExpand
Environmental temperature and growth faltering in African children: a cross-sectional study
Children living in hotter parts of sub-Saharan Africa are more likely to be wasted, underweight, and concurrently stunted and wasted, but less likely to been stunted, than in cooler areas, according to monthly mean daytime land surface temperature. Expand
What to Expect When It Gets Hotter
We use temperature variation within narrowly defined geographic and demographic cells to show that exposure to extreme temperature increases the risk of maternal hospitalization during pregnancy.Expand


Climate Extremes and the Length of Gestation
Extreme heat was associated with a reduction in the average gestational age of children delivered the next day, suggesting an immediate effect of this exposure on pregnant women. Expand
High ambient temperature and the risk of preterm delivery.
High ambient temperature was significantly associated with preterm birth for all mothers, regardless of maternal racial/ethnic group, maternal age, maternal education, or sex of the infant, and greater associations were observed for younger mothers, blacks, and Asians. Expand
Extreme Heat and Risk of Early Delivery Among Preterm and Term Pregnancies
High ambient temperature and extreme heat episodes may trigger earlier delivery among term births, and associations were stronger with early-term than with full-term delivery. Expand
Exposure to elevated temperatures and risk of preterm birth in Valencia, Spain.
Exposure to elevated temperatures was associated with an increased risk of preterm birth in the following three weeks. Expand
Relationship between season of birth, temperature exposure, and later life wellbeing
It is found that an extra day with mean temperatures above 32 °C in utero and in the first year after birth is associated with a 0.1% reduction in adult annual earnings at age 30, and that household air-conditioning adoption, which increased dramatically over the time period studied, mitigates nearly all of the estimated temperature sensitivity. Expand
Climate Change and Birth Weight.
Whether the temperature variation predicted to be part of climate change, including extreme high and low temperatures, historically has had negative health consequences through its effect on babies while in utero is documents. Expand
Maternal exposure to ambient temperature and the risks of preterm birth and stillbirth in Brisbane, Australia.
Examination of the relation between ambient temperature and preterm birth and stillbirth in Brisbane, Australia, between 2005 and 2009 provides strong evidence of an association between increased temperature and increased risk of stillbirth and shorter gestation. Expand
Effect of ambient temperature and air pollutants on the risk of preterm birth, Rome 2001-2010.
The results suggest a possible short-term effect of heat and a more delayed and prolonged effect of PM10 exposure on preterm-birth risk, as well as the existence of more susceptible subgroups of women. Expand
The relation of gestation length to short-term heat stress.
The data propose no special precautions for pregnant women exposed to short-term heat stress of the intensity evaluated in this study, however, the possible effects of chronic heat exposure on gestation cannot be ruled out. Expand
The influence of season and ambient temperature on birth outcomes: a review of the epidemiological literature.
Most of the studies found peaks of preterm birth, stillbirth and low birth weight in winter, summer or both, which indicates the extremes of temperature may be an important determinant of poor birth outcomes. Expand
