Two studies released Wednesday have linked toxic air pollution in Southern California to high cancer rates and complications with birth. Exposure to traffic-generated pollution increased the risk of major complications and premature birth, a report published in Environmental Health Perspectives online concluded. By measuring pregnant women's exposure to chemicals emitted by local traffic, the researchers concluded that the risk for preeclampsia, a condition that can lead to maternal and perinatal death, increased by as much as 42% at the highest exposures.

Low doses of aspirin can prevent pregnancy-induced hypertension and related toxemia in some women, according to two new studies that offer hope of the first effective method of averting a common and potentially fatal complication of pregnancy. The studies, published today in the New England Journal of Medicine, found that small amounts of aspirin during late pregnancy reduced the women's risk of high blood pressure and thus averted the need for sometimes-dangerous premature delivery.

Pre-eclampsia, a potentially deadly disorder that strikes about 5% of pregnant women, may be an autoimmune disease, Texas researchers reported Monday in the journal Nature Medicine. The team injected mice with antibodies isolated from women with the disorder, and the mice showed symptoms of the problem, including dangerously high blood pressure, protein in the urine and placental abnormalities. The effects of the antibodies could be blocked with the drug losartan, but the medication cannot be used in pregnant women because it can harm a fetus.

A disappointing new study has found that vitamin C and E supplements given to healthy pregnant women do not reduce their risk of developing preeclampsia, a complication that can be lethal to both the woman and her fetus. Preeclampsia happens when vessels in the womb constrict, cutting off blood and oxygen to the fetus. It occurs in late pregnancy and produces an increase in blood pressure. The condition kills about 76,000 women and fetuses a year worldwide.

Taking multivitamins around the time of conception dramatically reduces a woman's risk of preeclampsia, a complication during pregnancy that can be lethal to a woman and her fetus, researchers at the University of Pittsburgh report. Women who took multivitamins at least once a week three months before the start of pregnancy and three months after were 45% less likely to develop preeclampsia compared with women who did not take supplements, the study found.

Vitamin D deficiency increases the risk of life-threatening preeclampsia during pregnancy five-fold, Pennsylvania researchers reported Friday. Some researchers have suspected that low levels of vitamin D contribute to the disorder, which is characterized by soaring blood pressure and swelling of the hands and feet, but the new study is the first to examine its role directly.
