The guidelines for gestational diabetes stipulate that diagnosis should be made between the 24th and 28th week of gestation, as well as aftercare, should be carried out using a postpartum oral glucose tolerance test (oGTT) 6-12 weeks after delivery. There are, however, indications that this is not being done adequately in practice. Only around 40% of affected patients receive a post-partum oGTT after childbirth, and this often not within the intended timeframe of the guideline.
Answers to the two following main questions are sought in this project:
Which factors influence participation in post-partum oGTT?
Which factors influence the diagnostic result of the post-partum oGTT?
Data from the GestDiab register 2008 - 2017 serve as a database. GestDiab, a joint project between the Research Institution of Practising Diabetologists (winDiab) and the Professional Association of Diabetological Specialist Practices in the North Rhine (BdSN), provides the largest register on diabetes and pregnancy in Germany. Univariate and multiple logistic regressions are used to identify influencing factors such as demographic or lifestyle factors which are associated with (non)participation in post-partum oGTT or the resulting diagnosis.
