As a GP research registrar embarking on developing my first research project, I didn’t think I was going to change the world, but I hoped that I could, perhaps, influence a few. Obesity is a major global problem and maternal obesity is rising in addition to that of the general population. My aim was to change the health behaviour of the expectant mother.
The initial booking visit seemed a prime opportunity to offer health promotion and physical activity advice. As both the National Institute for Health and Care Excellence (NICE) guidelines and a Cochrane meta-analysis called for further research to aid weight management during pregnancy, I thought I would tackle this issue. My feasibility study aimed to recruit 30 women to be randomly allocated into either a pedometer-based physical activity intervention or to a control group. So far, so good.
Recruitment was a failure. Despite the enthusiasm of the recruiting GPs, midwives and myself, just six women across four practices agreed to take part over the five-month recruitment period. We had difficulty contacting potential participants because GP records did not always have up-to-date telephone numbers. Often, there was no answer to my calls or response to my voicemails. When I did speak to women on the phone, their reasons for non-participation or their failure to attend arranged meetings included lack of time, broken down cars and sick children.
Of the six women that we recruited, two dropped out; one, understandably, because of family issues, and one did not respond to my calls. Of the four women enrolled, one woman from the control group made it to the final hurdle. One of three women who completed the intervention didn’t make the final visit because she had gone into labour, another accidentally put her pedometer in the washing machine, and the third dropped her pedometer down the toilet!
To salvage my project from the same untimely “death by toilet,” I decided to conduct some semi-structured interviews with pregnant women attending their antenatal clinic appointments in their GP surgery and with those GPs and midwives involved in recruitment. Every cloud has a silver lining, and these interviews were most definitely my silver lining and may help research in the future: Everyone recognized the need for advice, and the general consensus from women was that they were open to advice on physical activity but were anxious that exercise could cause harm.
So, what have I learned? Feasibility studies are simply that — small studies to determine whether a project is doable, the intervention is acceptable and recruitment is possible. In its current format, this project is a no-goer. Perhaps we got it wrong. The qualitative interviews suggested that the next step would be to develop a group-based antenatal exercise program that GPs and midwives could signpost to women. This program could incorporate an educational component advising women about safe exercise during pregnancy and help to dispel age-old myths that exercise is harmful. To be continued……
