Scientific title | Effectiveness of regular weighing and feedback by community midwives in preventing excessive gestational weight gain: a randomised controlled trial (POPS 2) |
Study acronym | POPS2 |
Study objectives | During pregnancy many women gain too much weight because they do less physical activity and eat more food. This can lead to complications for the mother during pregnancy and it can also negatively affect the health of the baby. Weight gained during pregnancy which is not lost afterwards could lead to women becoming obese or starting subsequent pregnancies in an unhealthy weight state. There is a need therefore to evaluate interventions to prevent women gaining excessive weight during pregnancy. The ideal health professionals to help women do this are community midwives since they see women regularly throughout pregnancy and their role is to promote good outcomes for mother and baby. 490 women who are having a pregnancy without complications being cared for by community midwives will be eligible. Women will be randomised to receive usual care from their midwife or usual care plus the intervention. The intervention is led by community midwives who will regularly weigh pregnant women at routine antenatal visits, plot their weight on a weight gain chart, set parameters for healthy weight gain for each subsequent appointment, provide feedback on weight gain progress and encourage women to weigh themselves each week. Brief messages about the importance of eating healthily and physical activity during pregnancy Regular weighing of pregnant women by community midwives is not currently recommended in the UK. However our feasibility study has shown this type of intervention to be promising in preventing excessive weight gain during pregnancy and it does not cause women to become anxious. Weight will be measured at 10-14 weeks and 38 weeks of pregnancy to determine if they have gained excess weight. We also plan to interview up to 30 women and 30 community midwives about their experiences of participating in the study. |
Ethics approval(s) | 14/WM/1134; First MREC approval date 02/10/2014 |
Health condition(s) or problem(s) studied | Topic: Primary Care, Reproductive health and childbirth; Subtopic: Reproductive Health and Childb (all Subtopics), Reproductive health and childbirth; Disease: Reproductive Health & Childbirth, All Diseases |
Intervention | Women will be randomised to receive usual care from their midwife or usual care plus the intervention. Intervention: 1. Self-monitoring -The intervention will actively engage women in self monitoring by recording their weekly weight on a record chart. 2. Weighing - Community midwives will weigh women at each antenatal appointment and plot their weight on an IOM weight gain chart, appropriate to their BMI, set a maximum weight gain limit for each subsequent appointment, and give brief feedback on their progress emphasising the importance of healthy weight gain. Follow Up Length: 7 month(s) |
