  Purpose

There is an increasing trend in the society for developing obesity, type 2 diabetes and cardiovascular diseases. It is therefore important to identify the risk factors behind this tendency. Recent studies have shown that exposure to high blood sugar levels in pregnancy (as in mothers with type 1 diabetes) may play a role in the development of obesity, type 2 diabetes and cardiovascular diseases later in life for the children. Some studies suggest that high blood sugar levels during pregnancy can also affects cognitive function as well as growth and development of puberty. The mechanisms behind this are not sufficiently clarified yet.

In the period 1993-1999, pregnant women with type 1 diabetes in Denmark were followed and information about the course of pregnancy was collected, including the long-term blood sugar level during pregnancy and the children's' condition at birth. The unique opportunities in Denmark to identify and follow the children of these mothers and the possibility to select a comparison group of children of non-diabetic mothers gives a unique opportunity to examine the children of mothers with type 1 diabetes and accurately investigate the effect of blood sugar levels in pregnancy on conditions later in life.

There has not previously been made any study of this size and it is the investigators hope to be able to quantify the effect of blood sugar level during pregnancy on outcomes later in life. This will potentially give the possibility to detect individuals at risk for cardiovascular diseases earlier and to improve prevention targets in children of mothers with diabetes.

Enrollment: 584
Study Start Date: April 2012
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts
Exposure to intrauterine hyperglycemia
The study group includes the offspring of women with type 1 diabetes from the national diabetes birth registry (1993-99, n=900) with information of HbA1c prior to conception and/or 1st trimester HbA1c.
Control group
The control group including offspring of women without diabetes who delivered during the same period matched with respect to gender and age of offspring and the family's postcode as an indirect marker of the socioeconomic background.
