Plain English Summary

Background and study aims
It has been found that one year after giving birth up to 25% of women keep more than 4kg of the weight that they have gained during their pregnancy. This excess weight can increase the risk of developing diseases later in life. It has been suggested that additional interventions (i.e. programmes or treatments) can be included as part of existing public health appointments to tackle this issue for women after having a baby very cheaply. This study aims to include an intervention for women who have gained weight during their pregnancy into the national child immunisation programme, in order to test whether or not women feel this would be an appropriate measure to take and would help them to lose weight after having had their baby.

Who can participate?
Women who have given birth within the last four and eight weeks with a BMI of over 25kg/m2, and have not yet attended their first child immunisation visit.

What does the study involve?
Participants who have volunteered for the study are visited at home to measure their weight and gather personal information. They are then randomly allocated into one of two groups. All women are asked to weigh themselves weekly and record this on a record card attached the child’s ‘red book’ and aim for 0.5-1kg weight loss per week. Women in the first group are provided with a leaflet on healthy living, but otherwise no additional advice or assistance. For women in the second group, nurses make recommendations for healthier lifestyle choices and they are also advised to use an online weight loss programme. At each child immunisation (2, 3, 4 months old), nurses weigh the women to check their progress. A final weight measurement is then taken three months after women start the study. Women and nurses in the trial are then interviewed for feedback about what they think of the intervention.

What are the possible benefits and risks of participating?
The potential benefits of participating in the study include weight loss and improved self-management of weight. There are no potential risks of the intervention to individual participants. However, we will be monitoring immunisation and breastfeeding rates to investigate if the intervention has an impact on these behaviours.

Scientific title

Feasibility and acceptability of a routine weight management intervention for postnatal women embedded within the national child immunisation programme



Study hypothesis

A brief routine weight management intervention for women in the postnatal period that promotes self-management through self-monitoring and signposting to an online weight management programme and is embedded within the child immunisation programme may be feasible and acceptable both to patients and health care professionals.

Postnatal weight gain and obesity


Intervention Group: The intervention is embedded within pre-existing immunisation contacts, when babies are two, three and four months old. The intervention involves nurses encouraging women in the postnatal period to make healthier lifestyle choices though self-monitoring of weight and signposting to a female specific online weight management programme.

Comparison Group: Women will receive a healthy lifestyle leaflet and no other intervention.

Women will be asked to weigh themselves weekly and record this on a record card attached to the child’s red book, with a goal of losing 0.5kg per week. The practice nurse will weigh the women at each child immunisation to assess their progress against their weight loss goal. Follow-up of weight will be three months after randomisation. Semi-structured interviews with both participants and nurses will be carried out at the end of the trial to obtain their views of the intervention.
