2413-PUB: Demographics of Women with Type 1 Diabetes Attending a Diabetes and Pregnancy Clinic, 2000-2002, 2010-2012, and 2014-2016

Abstract

Background: The numbers of women attending Diabetes and Pregnancy Clinics (DPC) are increasing. Some of the increase may reflect obesity effects on GDM prevalence, but changes in numbers and characteristics of women with type 1 diabetes (T1DM) are unknown. The DPC in London Ontario sees all pregnant women with diabetes within the catchment area with stable clinic structures and procedures. Longitudinal characteristics of women with T1DM 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, A1C and medication use. Continuous results were analyzed by one-way analysis of variance (ANOVA); non-parametric results by Chi-square testing; p≤ 0.05 signifying significance. Conclusions: Clinic numbers of pregnant women with T1DM increased non-significantly over the study timeline while pump usage rose concurrent with access to government funding. A1C values fell 0.5% from first to last visit in all time periods. A1C values at first visit rose over the time periods suggesting women with less optimal glucose control were conceiving pregnancies.
