"Few studies on job stress relative to pregnancy have been carried out, but both animal and epidemiological studies have shown effect of exposure to stressful conditions during pregnancy and adverse effects on the offspring."
MiscarriageFetus death risk reduction is included in the United Nations Sustainab — Miscarriage
"Fetus death risk reduction is included in the United Nations Sustainable Development Goals. However, little is known about how missed abortion in the first trimester (MAFT) is related to maternal air pollution exposure. We quantify the link between air pollution exposure and MAFT in Beijing, China, a region with severe MAFT and air quality problems. We analyse the records of 255,668 pregnant women from 2009 to 2017 and contrast them with maternal exposure to air pollutants (particulate matter PM2.5, SO2, O3 and CO). We adjust for confounding factors such as sociodemographic characteristics, spatial autocorrelation and ambient temperature. We find that, for all four pollutants, an increased risk of MAFT is associated with rises in pollutant concentrations, and the adjusted odds ratios (ORs) of these associations increase with higher concentrations. For example, the adjusted OR of MAFT risk for a 10.0 μg m−3 increase in SO2 exposure is between 1.29 and 1.41 at concentrations of 7.1–19.5 μg m−3; it drops to 1.17 below this range and rises to 1.52 above it at higher SO2 concentrations. This means that the risk increase is not linear but becomes more severe the higher the pollutant concentration. The findings provide evidence linking fetus disease burden and maternal air pollution exposure."

Miscarriage, also known in medical terms as a spontaneous abortion, is an end to pregnancy resulting in the loss and expulsion of an embryo or fetus from the womb before it can survive independently. Miscarriage before six weeks of gestation is defined as biochemical loss by ESHRE. Once ultrasound or histological evidence shows that a pregnancy has existed, the term used is clinical miscarriage, w

"Dr Sarah Stock, at the University of Edinburgh and not part of the research team, said: “Air pollution is clearly detrimental to the health of millions of mothers, babies and children worldwide. Measures to reduce the impact of air pollution are crucial to ensure the health of future generations.”"

"In the existing body of literature, exercise during pregnancy has generally not been associated with miscarriage,17–19 and one case–control study has even reported a protective effect of exercise during pregnancy.20 In contrast, Hjollund et al.21 found an increased risk of early miscarriage among women who reported a high physical strain around the time of implantation of the embryo. Furthermore, lay people have tried to use excessive physical exercise as an abortifacient, and older literature mentions physical activity (e.g. jumping, running, and horseback riding) as a cause of miscarriage. Considering the relatively sparse literature and the somewhat inconsistent results, we wanted to examine the association between exercise during pregnancy and miscarriage in a large population-based cohort."

"The main results based on the total data material showed that an increasing amount of time spent on exercise was associated with a greater risk of miscarriage compared with non-exercisers. Exercising 1–44 minutes/week was not associated with an increased risk of miscarriage."

"It is difficult to investigate very early miscarriages using prospectively collected exposure information, since the time period, in which collection of exposure information must take place, that is, the time from detection of pregnancy to the occurrence of an early miscarriage, is short."

"Because spontaneous miscarriage and self-managed abortion are medically indistinguishable in most cases, prohibitions on abortion will predictably lead to the investigation and detention of many women experiencing miscarriages as well as those self-managing abortions."
