Pregnant women's experience of undergoing an oral glucose tolerance test: A cross-sectional study

Aims: The oral glucose tolerance test (OGTT) is routinely performed in most pregnancies; however, there are few studies which document the experience of taking this test. We assessed the experience of pregnant women during an OGTT. Methods: This cross-sectional study included 152 women (24-32 weeks' gestation) and assessed their knowledge, anxiety (Spielberg anxiety inventory test-STAI), and physical pain (0-10 visual analog scale) during the OGTT. The Friedman test was used to compare pain scores over time. Results: 61 (40%) participants did not know why they were doing the OGTT and 73 (48%) women had high state-anxiety levels (STAI & GE; 41 points, 20-80 scale). Participants had mild to moderate pain scores immediately after the first and second blood draws (3.9 & PLUSMN; 2.7 and 3.8 & PLUSMN; 2.3, respectively) that decreased significantly after the third blood draw (2.8 & PLUSMN; 2.4, P < 0.001). Nearly half (n = 71, 47%) of the participants were very or extremely bothered with having to drink the glucose solution. Conclusions: The OGTT was associated with high levels of anxiety and mild to moderate physical pain. Ingestion of the glucose solution was perceived as the most difficult part of the test. Good strategies can help to mitigate some of these negative experiences while undergoing an OGTT.

Automated summary

This study assessed the experience of pregnant women during an OGTT and found that participants generally experienced anxiety and mild to moderate physical pain. Drinking the glucose solution was perceived as the most difficult part of the test.
