Plain English Summary
Background and study aims:
Every day around 84 pregnant women are diagnosed with gestational diabetes in the UK. While every woman with gestational diabetes receives care and treatment from their diabetes care team there are very few resources available to help women understand their diagnosis and inform them how best to manage their diabetes. To address this issue we have developed a DVD called: Gestational Diabetes.... what you need to know (but maybe dont!). This DVD has been designed and produced with continuous input from women with gestational diabetes and health care professionals. We do not know if this DVD will be of any additional benefit to women with gestational diabetes. Therefore the purpose of this study is to find out whether watching this DVD when diagnosed with gestational diabetes will have any effect on the understanding of the condition and how best to manage it, including the effect on blood sugar control or levels of stress and anxiety.
Who can participate?
All women who are aged 16 years or older, who recently have been diagnosed with gestational diabetes for the first time.
What does the study involve?
Participants will be asked to complete questionnaires on three separate occasions. Each visit will take place during routine antenatal clinic visits. The first visit will take place as soon as possible after diagnosis of gestational diabetes. The women will be asked to complete 6 short questionnaires about how they are feeling about their pregnancy and gestational diabetes diagnosis and about their diet. This will take 25 - 30 minutes. Half of the women taking part in the study will be given the DVD to watch at home (46 minutes long), and the other half will not be given the DVD. This is so we can compare the results of the two different groups to see if one is better. The women will be put into a group by chance (randomly), with the decision about which group randomly decided by a computer programme operated by an independent department. All women taking part in the study will receive the same care from their diabetes care team. Women who receive the DVD, will be asked to watch it as soon as you have some free time and will receive a follow-up call or text message to remind them to watch it. The second visit takes place two weeks later during a routine clinic appointment. The women will be asked to complete the same 6 questionnaires which will take 25 - 30 minutes. The third visit will take place about 6-8 weeks after the babys delivery during a routine postnatal visit. The women will be asked to complete 3 questionnaires which will take approximately 20 minutes. As part of usual care, the diabetes care team will ask all women with gestational diabetes to monitor their blood sugar level with a blood glucose meter throughout their pregnancy. The researcher will download the readings from the meter at study visit 2 and at around 36 weeks gestation.
What are the possible benefits and risks of participating?
Taking part in this study may improve the participants knowledge of gestational diabetes and how to manage it. Those who do not receive the DVD as part of this study will receive a copy at the end of the study to keep. The content of the DVD may also be beneficial for after the delivery of the baby, and in any future pregnancies. The main disadvantage of taking part in the study is having to give up some spare time to complete the questionnaires and watch the DVD. However, to reduce this inconvenience we have scheduled the study visits to at the same as routine clinic appointments and questionnaires can be completed over the phone if preferred.
