A Culturally-tailored Personalized Nutrition Intervention in South Asian Women at Risk of Gestational Diabetes

This study is looking for pregnant women who are between 12 and 18 weeks pregnant and have ancestors from South Asian countries like India, Pakistan, Bangladesh, or Sri Lanka. You should be expecting one baby, not twins or more.

You might be suitable to join if you have at least two of the following: you're over 29 years old, your usual diet isn't very healthy, you have a close family member (like a parent or sibling) with type 2 diabetes, you had gestational diabetes in a previous pregnancy, or your pre-pregnancy body mass index (BMI) was 23.17 or higher.

We would not be able to include you if you already have type 1 or type 2 diabetes, have high blood pressure, find it difficult to understand English, are not willing to change your eating habits, or have other serious pregnancy risks (like expecting twins, using fertility treatments, or having a history of certain pregnancy problems). You also need to have a smartphone and be willing to walk, and not be experiencing severe sickness or already taking part in another medical study.

If you join this study, you will be randomly placed into one of two groups. One group will receive special advice on healthy eating that's tailored to South Asian cultures and delivered by a trained health coach. The other group will receive the usual advice about healthy eating during pregnancy. The study will involve regular checks of your blood sugar levels, likely through blood tests after drinking a special sugary drink. You'll also be asked about your diet and overall health. The specific number of visits or assessments will be explained to you, but the study will follow you through your pregnancy to see how the advice impacts your health and your baby's health. We expect the study to last for the duration of your pregnancy and potentially for a short period after your baby is born.
