Abstract:

Objective

To determine whether women with a history of fertility problems have a higher risk of gestational diabetes mellitus (GDM) than women without a history of fertility problems after adjustment for maternal factors.

Design

Nationwide population-based cohort study.

Setting

Not applicable.

Patient(s)

All live and stillbirths during 2004–2010 among women with fertility problems (n = 49,616) and women without fertility problems (n = 323,061) were identified by linkage between the Danish Medical Birth Registry and the Danish Infertility Cohort. Information on GDM was obtained from the Danish National Patient Registry.

Intervention(s)

None.

Main Outcome Measure(s)

Odds ratios and 95% confidence intervals for the association between fertility problems and risk of GDM after adjustment for potentially confounding factors, including maternal age, prepregnancy BMI, parity, parental history of diabetes, level of education, and smoking during pregnancy.

Result(s)

In total, 7,433 (2%) pregnant women received a diagnosis of GDM. Multivariate analysis showed that pregnant women with a history of fertility problems had a statistically significantly higher risk of GDM than pregnant women without fertility problems. In stratified analyses, the association between fertility problems and risk of GDM attenuated with increasing age and was more pronounced among primiparous women and women with polycystic ovary syndrome.

Conclusion(s)

Our findings suggest that pregnant women with a history of fertility problems are at increased risk of GDM.
