Maternal obesity


The programme will commence at 16-20 weeks and last for approximately 20 weeks. The total duration of follow-up will be up to 6 months post-delivery.

The components are as follows:
At the group sessions healthy eating topics will include:
1. Low glycaemic index food which is patient and culturally focused
2. Fruits and vegetables
3. Reduced saturated fat intake
4. Food label reading
5. Portion sizes
6. More often rather than three big meals a day
7. Reduced sugar intake (especially sugar-rich beverages)
8. Supermarket tour
9. Basic cooking skills and recipe try-outs

Physical activity:
A menu of exercise choices, based on the participant's wishes and local availability will be offered. A participant will be able to choose, for example, weekly exercise sessions (land-based low impact exercise such as cycling and dancing and water-based exercise such as swimming and aqua-aerobics) which are provided in Lambeth by such organizations as Aqua_Natal and Sport England. Group exercise sessions will be fun, structured and non-competitive. For those that prefer exercising alone, walking is one of the menu options as the means to achieving agreed personal goals.

Postnatal women will be referred onto existing and well-established resources in the Children's Centres including breastfeeding cafés, mother and baby exercise classes and baby massage courses.

Behavioural change:
This psychology-based component will help women to change lifestyle through both one-to-one and group-based motivational sessions using a solution and problem-solving approach.
