We highlight 3 recent studies concerning pregnancy and diabetes and ways to potentially reduce health risks of both mother and child.
A 2014 study by the Centers for Disease Control estimates gestational diabetes rates are as high as 9.2% annually in the US. Women with gestational diabetes are at a high risk of developing pregnancy and delivery complications and experience a 7-fold increased risk of developing type 2 diabetes later in life. Children of mothers with gestational diabetes are more likely to develop impaired glucose tolerance and metabolic complications.We present 3 recent studies that discuss the topics of pregnancy and diabetes and ways to potentially reduce the risk of diabetes for both the mother and child.Source: DeSisto CL, et al.

Caesarean Delivery Linked to Increased Risk of Childhood Obesity and Type 1 Diabetes. Rates of caesarean section are rising; repeat caesarean and maternal request contribute to this increase.Data linking caesarean delivery to chronic disease is observational.An adjusted analysis found caesarean delivery increased the relative risk of childhood type 1 diabetes by 19%, as well as increased risks of obesity and asthma.Unless medically indicated, researchers believe possible child health risks should be considered before performing a caesarean section.Source: Blustein J, et al.

Exercise Helps Prevent Gestational Diabetes and Reduce Weight Gain During Pregnancy.Gestational diabetes can have long-term effects on the mother, such as impaired glucose tolerance and type 2 diabetes.Children whose mothers had gestational diabetes are more likely to become overweight or obese, therefore increasing their risk of developing diabetes.More than 2800 pregnant women in Spain who did little or no exercise were enrolled into exercise programs.Analysis of 13 trials showed that exercise reduced the risk of gestational diabetes more than 30%.Source: Diesel JC, et al.

Women Delivering Males More Likely to Develop Gestational Diabetes.It is believed gestational diabetes occurs due to a combination of metabolic abnormalities in the mother and temporary metabolic changes that happen during pregnancy.Researchers analyzed insurance records of almost 643,000 women from Ontario delivering their first child between April 2000 and March 2010 for the rate of diabetes cases.Women having boys were more likely to develop gestational diabetes.Women who developed gestational diabetes and had a girl were more likely to develop type 2 diabetes.Findings suggest carrying a male creates greater pregnancy-associated metabolic changes.Sources: Retnakaran R.

Take-home Points.The increased risk of developing childhood obesity, asthma, and type 1 diabetes should be considered before performing a non-medically necessary caesarean section.Exercise was shown to help prevent the risk of gestational diabetes and reduce weight gain in pregnancy, conditions which could result in long-term impaired glucose tolerance and type 2 diabetes.Women delivering sons are more likely to develop gestational diabetes, suggesting carrying male fetuses could lead to greater metabolic changes during pregnancy.
