Dietary optimisation as a defence against gestational diabetes
This study aims to understand if changing your diet early in pregnancy can help prevent gestational diabetes, a type of high blood sugar that starts during pregnancy. Gestational diabetes can affect both mum and baby. Researchers will invite 75 pregnant women at higher risk to take part. They will be split into three groups, each following a different eating plan provided in 'diet boxes' for several weeks. The goal is to see if these diets can improve how the body controls sugar levels. Participants will receive free food and extra health checks, hoping to find new ways to keep mothers and babies healthy during and after pregnancy.
En un coup d'œil
De quoi parle cette étude ?
Each year, around 100,000 pregnant women in the UK develop gestational diabetes. This is when blood sugar levels become too high during pregnancy. It can pose health risks for both the mother and the baby, not just during pregnancy but also later in life. When you're pregnant, your body works hard to provide everything your baby needs. Hormones from the placenta can make it harder for your body to use insulin effectively, which is the hormone that controls blood sugar.
Most women's bodies naturally make more insulin to keep their blood sugar stable. However, some women can't produce enough extra insulin, leading to high blood sugar levels and, therefore, gestational diabetes. We don't fully understand why some bodies adapt better than others. While some reasons are genetic, meaning they're inherited, there must also be other factors at play, because not all women who have gestational diabetes in one pregnancy get it again in a future pregnancy. By understanding these non-inherited causes, we hope to find new ways to prevent or manage gestational diabetes.
This study will explore whether changing your diet and how your body stores fat early in pregnancy can improve how your body handles sugar. We plan to invite 75 pregnant women who have a higher chance of developing gestational diabetes. They will be divided into three groups: one group will follow a diet designed to reduce body fat, another will follow a diet focused on changing where the body stores fat, and the third group will stick to a standard diet. The aim is to see if any of these dietary changes can help mothers-to-be maintain healthy blood sugar levels.

Qui peut être éligible ?
You might be able to join this study if you are at least 18 years old and are up to 16 weeks pregnant. You also need to have a body mass index (BMI) over 25, and at least one risk factor for gestational diabetes. Examples of risk factors include having a family history of diabetes, having had gestational diabetes before, or having a history of polycystic ovary syndrome.
It's important that you plan to receive all your antenatal care at the study centre and are happy to give your consent to take part. If you need support with language, an interpreter can help you understand everything.
However, you won't be able to join if you are pregnant with more than one baby (e.g., twins), or if you have certain health conditions like severe kidney, liver, or heart problems, or psychiatric conditions that need hospital care. You also can't take part if you are taking certain medications like high-dose steroids, have severe anaemia, or if you already have type 1 or type 2 diabetes. People with very specific dietary needs, such as being vegan or having severe allergies, also won't be able to join.

En quoi consiste la participation ?
If you join the study, you'll first have some measurements taken, including your body make-up, what you usually eat, and how active you are. Then, you'll be placed into one of three diet groups: a control group, a reduced-calorie group, or a reduced-carbohydrate group. For several weeks, starting between 12-16 weeks of pregnancy and lasting until 24-28 weeks, nutritious 'diet boxes' with your meals will be delivered to your home every week. You'll have follow-up appointments that will fit in with your usual check-ups at 20, 24-28, and 36 weeks of pregnancy. After your baby is born, you'll also have follow-up visits at 3, 12, and 24 months. While taking part in the study, you will wear a sensor to track your blood sugar levels. Overall, the study will last from when you join early in your pregnancy until 24 months after your baby is born.
