The recurrence risk of gestational diabetes according to the number of abnormal values in the oral glucose tolerance test.

ABSTRACT:

Introduction

Oral glucose tolerance test (OGTT) results may be used to estimate the risk of recurrent gestational diabetes mellitus (GDM) in a subsequent pregnancy in the different study settings. This study assesses the association between the number of abnormal glucose values in the OGTT in the first pregnancy and GDM recurrence in a subsequent pregnancy in a Nordic cohort.

Material and methods

This register-based cohort study included 1677 women who had their first singleton delivery in 2009, underwent a 75 g 2-h OGTT during the pregnancy, and gave birth at least once more within 10 years according to the Finnish Medical Birth Register. The cut-off values were as follows: ≥5.3 mmol/L at fasting, ≥10.0 mmol/L at 1 h, and ≥8.6 mmol/L at 2 h. The odds ratio (OR) for GDM recu
