Smoking in Pregnancy Research Group

The Smoking in Pregnancy research group is based within the Centre for Public Health and Epidemiology in the School of Medicine at the University of Nottingham.

With collaborators around the UK and internationally, our research group is a leading centre for research on Smoking in Pregnancy.

Watch the video for an overview of our research and the work we are doing to help reduce smoking rates in pregnancy and prevent women from returning to smoking after they have had their babies.

The issue

Smoking in pregnancy is the biggest cause of harm to babies, very young infants and to mothers. In the UK up to 12% of women smoke throughout pregnancy and this is completely reversible. Pregnancy motivates around 50% of smokers to stop but many women either can’t stop during pregnancy or, if they do, they re-start smoking again afterwards.

Our aims

Reduce smoking rates in pregnancy and to prevent women from returning to smoking after they have had their babies.
Develop and test effective methods for helping pregnant women to quit smoking and prevent relapse after childbirth.
Influence health policy and NICE recommendations to ensure that evidence-based methods for encouraging cessation and preventing relapse are used in routine clinical practice.

Focus

We design and conduct trials to test out new ways of helping women to stop smoking when they are pregnant. We are skilled in applied health services research, health psychology, behavioural sciences, statistics, qualitative research, systematic review, epidemiology, economics and analysis of large, routine databases.

Have you ever smoked while you have been pregnant or very soon afterwards? If so we would be keen to hear from you. We need to hear your views to help us design research which is relevant and useful for women who smoke when pregnant.

Projects

Outcomes

We have completed randomised controlled trials (RCTs)^1-3, systematic reviews^4-6 and database studies^{7 8} investigating nicotine replacement therapy (NRT) use in pregnancy; these suggest NRT is safe in pregnancy but at standard doses, has borderline efficacy. We helped update of an authoritative review of psychosocial interventions for smoking cessation in pregnancy⁹ led by an Australian team.
We found that identifying smokers at fetal ultrasound appointments using exhaled carbon monoxide and referring them for NHS smoking cessation support doubles the proportion of women who successfully stop smoking.^{10 11}
We are investigating ways of making text-based intervention for smoking cessation in pregnancy available to pregnant smokers over the internet.^{12 13}
We are refining an economic model for valuing smoking cessation in pregnancy and will make this available for other researchers to use.^14-16
We are developing behavioural support methods tailored which are tailored for pregnant smokers and which will be incorporated into mandatory national online training modules provided by the National Centre for Smoking Cessation and Training (NCSCT) for NHS smoking cessation advisors.
