Background and study aims
Gestational diabetes (GDM) is a common pregnancy-related condition which causes high blood glucose (sugar) levels and increases the risk of damaging effects for both mother and baby. The prevalence of GDM has increased by about a third over the past decade, and this is mainly explained by an increase in obesity. GDM is usually diagnosed at 24-28 weeks of pregnancy and little is known about blood glucose levels in early pregnancy. Although preventing GDM is recognised as a priority by Diabetes UK, the most effective strategies have yet to be identified.
In Oxford, a remote monitoring digital application called GDm-Health™ has been developed. GDm-HealthTM supports management of GDM by a smart phone app that automatically transmits blood glucose measurements to a secure web site and allows for communication between healthcare professionals and women with GDM via texts. This system is clinically reliable and highly satisfactory to women with GDM, but has only been proven in women in later pregnancy with a confirmed diagnosis of GDM. The researchers are interested in applying this technology earlier in pregnancy to investigate its usefulness for prevention or earlier detection and management of GDM. However, asking women to test blood glucose levels before a formal diagnosis may be challenging and for this reason the researchers intend to conduct a qualitative study asking women for their opinions about this.

Who can participate?
Female, aged 18 years or above, in the first trimester of pregnancy, and at risk of GDM.

What does the study involve?
The researchers intend to recruit 40 women at risk of developing GDM at their routine 12-week nuchal scan and invite them to take part in a recorded interview that lasts approximately 30 minutes. The researchers will ask a series of open questions about blood testing and strategies for GDM prevention, including diet and physical activity, transcribe the interviews and apply thematic analysis.

What are the possible benefits and risks of participating?
It is likely that there is little apparent benefit for women taking part in this study, although some may feel better knowing they are contributing to other women’s well-being in the future. Women may also appreciate being able to discuss their personal challenges and having their opinions sought. Some women may feel distress when asked to discuss personal feelings and opinions.

Study acronymp-GDm
Study objectivesWomen at risk of gestational diabetes would be willing to engage with preventative measures, including blood glucose monitoring, dietary and physical activity interventions in early pregnancy and before a formal diagnosis of gestational diabetes
Ethics approval(s)Approved 27/02/2020, West of Scotland REC 5 (West of Scotland Research Ethics Service, Ward 11, Dykebar Hospital, Grahamston Road, Paisley, PA2 7DE, UK; +44 (0)141 314 0213; WoSREC5@ggc.scot.nhs.uk), ref: 20/WS/0054
