Study: Diabetes In Pregnancy Increases Heart Disease Risk

Women with pregnancy-related diabetes are at higher risk for developing cardiovascular disease in the decade after childbirth, a research review suggests.

While so-called gestational diabetes has long been linked to an increased risk of heart disease later in life, some previous research suggests this risk may depend on whether the condition evolves into type 2 diabetes that persists after delivery.

Researchers examined data from nine previous studies with almost 5.4 million mothers. Overall, about 8,000 women with a history of gestational diabetes experienced cardiovascular events like heart attacks and strokes, as did more than 93,000 women without this pregnancy complication.

“This study demonstrates that women with gestational diabetes have a 2-fold higher risk of major cardiovascular events than their peers,” said senior study author Dr. Ravi Retnakaran of the University of Toronto.

“This increased risk is not dependent upon (type 2 diabetes),” Retnakaran said by email. “The risk differential between women with gestational diabetes and their peers emerges within the first decade after pregnancy.”

Compared to women who didn’t have gestational diabetes, those who did had a 2.3-fold greater risk of events like heart attacks and strokes within the first decade after giving birth.

Study: Vitamin D Supplements During Pregnancy Doesn’t Impact Infants Growth

Even in a population of women with vitamin D deficiency, supplementation of high-dose vitamin D from mid-pregnancy until birth and for 6 months postpartum shows no benefits on measures of fetal or infant growth compared with prenatal supplementation only, or placebo, according to a study of more than 1100 women and their infants.

“Vitamin D supplementation given to women during the latter half of pregnancy and in the postpartum period improved biochemical markers of vitamin D status and reduced the risk of vitamin D deficiency, as expected. However, even at higher than conventional doses, vitamin D supplementation did not have effects on infant growth up to 1 year of age,” first author Daniel Roth, MD, PhD, an associate professor in the departments of pediatrics and nutritional sciences at the University of Toronto, Ontario, told Medscape Medical News.

Driving While Pregnant: 2nd Trimester pregnant women more likely to get in car crash, study says



So “Driving While Pregnant” is a thing.
New research published today in the Canadian Medical Association Journal suggests that women who are in their second trimester of pregnancy are 42% more likely  to get involved in a serious multi-car crash. 
The data impacted all groups of pregnant second-trimester women across different socioeconomic and racial groups.
Researchers stopped short of recommending that pregnant women not drive but instead warned that they should be extra mindful of the risk while driving. 
“It amounts to about 1 in 50 statistical risk of the average women having a motor vehicle crash at some point during her pregnancy,” Donald Redelmeier of the University of Toronto said in a release.
