air pollution induced missed abortion risk for pregnancies
Nature Sustainability, 2019Co-Authors: Liqiang Zhang, Weiwei Liu, Kun Hou, Jintai Lin, Chenghu Zhou, Xiaohua Tong, Ziye Wang, Yuebin Wang, Yanxiao Jiang, Ziwei WangAbstract: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. A study of over 250,000 pregnant women in Beijing, China, finds that missed abortion is associated with the concentration of four major air pollutants. The association is not linear but becomes stronger with higher concentrations.

The Role of Iron Adequacy for Maternal and Fetal Health
'Indonesian Nutrition Association', 2021Co-Authors: Sungkar AliAbstract:Nearly half of pregnant women in the world are reported to suffer anemia. And most of them are caused by iron deficiency, while the others by folate, vitamin B12 or vitamin A deficiency, chronic inflammation, parasite infections and hereditary disorders. Anemia in pregnant women is characterized when < 11 g / dL or any time during pregnancy. And when followed by low iron, it's called iron deficiency anemia. Iron plays an important role in many metabolic processes by transporting oxygen and allowing cells to generate energy. Low iron levels during pregnancy leading to anemia, related to an heightened risk of mother and Fetus Disease. Iron deficiency anemia can affect fetal development and persist long-term, while mild and serious pregnancy anemia can lead to premature birth, maternal and child mortality, bleeding, and infectious Disease. The iron requirement during pregnancy exceeds 1000 mg for red cell expansion, 300 mg – 350 mg for developing Fetus and placenta, and 250 mg for variable blood loss at delivery. Iron adequacy during pregnancy can be assured by proper nutrition, iron supplementation and fortification, and intravenous iron or blood transfusion. Iron supplementation is only enough to cover the prenatal iron requirements. Summary: Iron deficiency leading to anemia, rising risk of negative pregnancy outcomes. To meet increasing iron requirements during pregnancy including iron supplementation, fortification of staple iron foods, and intravenous iron or blood transfusion if required
