Metabolic status before pregnancy predicts subsequent gestational diabetes

13.10.2010
Study suggests women and their children may benefit from metabolic screening prior to conception

Cardio-metabolic risk factors such as high blood sugar and insulin, and low high density lipoprotein cholesterol that are present before pregnancy, predict whether a woman will develop diabetes during a future pregnancy, according to a Kaiser Permanente study in the current issue of the American Journal of Epidemiology.

The study suggests that metabolic screening of all women before pregnancy, particularly overweight women, could help identify those more likely to develop gestational diabetes mellitus, known as GDM, in a subsequent pregnancy and help them take preventive steps prior to conception.

Women who develop GDM during pregnancy are more likely to develop Type 2 diabetes after pregnancy, previous research has shown. GDM is defined as glucose intolerance that typically occurs during the second or third trimester and causes complications in as much as 7 percent of pregnancies in the United States. It can lead to early delivery and Cesarean sections and increases the baby's risk of developing diabetes, obesity and metabolic disease later in life.

The study is among the first to measure cardio-metabolic risk factors before pregnancy in women 18-30 years of age without diabetes who later became pregnant and reported whether they had developed GDM. The research provides evidence to support pre-conception care for healthy pregnancies as noted in a 2006 report by the U.S. Centers for Disease Control and Prevention. That report suggested that risk factors for adverse outcomes among women and infants can be identified prior to conception and are characterized by the need to start, and sometimes finish, interventions before conception occurs.

"Our study suggests that women may benefit from a focus on care before conception that would encourage screening for metabolic abnormalities before pregnancy, rather than only during pregnancy. Because weight loss is not advised, and the medication and behavioral treatment options are more limited during pregnancy, the time to prevent gestational diabetes is before pregnancy begins," said study lead investigator Erica P. Gunderson, PhD, an epidemiologist and research scientist at the Kaiser Permanente Division of Research in Oakland, Calif. "Screening and treatment of metabolic risk factors before pregnancy to prevent GDM may help reduce its lasting adverse health effects on children, by possibly improving the uterine environment," she added.

Researchers studied 1,164 women without diabetes before pregnancy who delivered 1,809 live births during the course of five consecutive exams from 1985-2006 as part of a Coronary Artery Risk Development in Young Adults study. Participant characteristics – including lifestyle, socio-demographic, medical conditions, medication use, family history of diabetes, pregnancies and births and GDM status, as well as clinical assessments, body measurements and blood specimens – were obtained at baseline. Follow-up exams used standardized research methodologies, including self- and interviewer-administered questionnaires.

Impaired fasting glucose, elevated fasting insulin and low HDL-cholesterol before pregnancy were associated with higher risk of GDM. Of the 1,809 live births studied, 154 (8.5 percent) involved a GDM pregnancy.

Among overweight women, 26.7 percent with one or more cardio-metabolic risk factors before pregnancy developed gestational diabetes versus 7.4 percent who did not have cardio-metabolic risk factors.

Although obesity and belly fat are antecedents to insulin resistance, pre-pregnancy obesity was not independently predictive of GDM after taking into account cardio-metabolic risk factors. Researchers also found no association between pre-pregnancy blood pressure or hypertension and risk of GDM, possibly due to the low prevalence of these conditions in healthy women of reproductive age.

This study is part of ongoing research at Kaiser Permanente to understand, prevent and treat gestational diabetes. Recent Kaiser Permanente research includes:

A study in The American Journal of Obstetrics and Gynecology found there is an increased risk of recurring gestational diabetes in pregnant women who developed gestational diabetes during their first and second pregnancies. http://xnet.kp.org/newscenter/pressreleases/nat/2010/071210gestationaldiabetes.html

A study in Diabetes Care of 10,000 mother-child pairs showed that treating gestational diabetes during pregnancy can break the link between gestational diabetes and childhood obesity. That study showed, for the first time, that by treating women with gestational diabetes, the child's risk of becoming obese years later is significantly reduced. http://xnet.kp.org/newscenter/pressreleases/nat/2007/082707gestationaldiabetes.html

A study in Obstetrics & Gynecology of 1,145 pregnant women found that women who gain excessive weight during pregnancy, especially in the first trimester, may increase their risk of developing diabetes later in their pregnancy. http://xnet.kp.org/newscenter/pressreleases/nat/2010/022210pregnancyweightgain.html

A study in Ethnicity & Disease of 16,000 women in Hawaii found that more than 10 percent of women of Chinese and Korean heritage may be at risk for developing gestational diabetes. http://xnet.kp.org/newscenter/pressreleases/nat/2009/121109diabetespregnancy.html

Co-authors of the current study include Charles P. Quesenberry, PhD; Juanran Feng, MS, and Stephen Sidney, MD, MPH, all from the Kaiser Permanente Division of Research; David R. Jacobs, PhD, the Division of Epidemiology and Community Health, School of Public Health, University of Minnesota; and Cora E. Lewis, MD, MSPH, Division of Preventive Medicine, University of Alabama at Birmingham.

The study was funded by the National Institutes of Health, the National Heart, Lung and Blood Institute, the National Institute of Diabetes and Digestive and Kidney Diseases and the American Diabetes Association.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
