Background: Numbers of women attending Diabetes and Pregnancy Clinics (DPC) are increasing. Potential reasons include: obesity; fertility intervention access; diagnostic changes for gestational diabetes (GDM). The DPC in London Ontario sees all pregnant women with diabetes within the catchment area with stable clinic structure and procedures. Longitudinal characteristics of GDM women were documented for demographic insights.

Methods: DPC pregnancy charts were assessed for 2000-2002, 2010-2012 and 2014-2016. Data were abstracted for: age; weight, infertility interventions; GDM diagnostic method. Continuous results were analyzed by one-way analysis of variance (ANOVA), non-parametric results by Chi-square testing; p≤ 0.05 signifying significance.

Conclusions: Over the study interval, women with a GDM diagnosis increased 240%. The change may be related to obesity; changes to GDM diagnostic criteria and week of testing; but not late pregnancy weight gain or use of fertility interventions.
