Durham Uni Study Shows Smoking Effects On Unborn Babies

Pioneering research from Durham University could help pregnant mams quit smoking by letting them see the effects on their baby before it's born.

That's according to the woman behind the new study, Dr Nadja Reissland.

Monitoring of mothers attending hospital in Middlesbrough found harmful effects of smoking during pregnancy on unborn babies may be seen in tiny movements in their faces using 4-d ultrasound scans.

Pregnant women have long been urged to give up cigarettes because they heighten the risk of premature birth, respiratory problems and even cot death.

Now researchers believe they can show the effects of smoking on babies in the womb - and use the images to encourage mothers who are struggling to give up.

Dr Nadja Reissland has studied moving 4-d scan images and recorded thousands of tiny movements in the womb.

She monitored 20 mothers attending the James Cook University Hospital in Middlesbrough, four of whom smoked an average of 14 cigarettes a day.

After studying their scans at 24, 28, 32 and 36 weeks, she detected that foetuses whose mothers smoked continued to show significantly higher rates of mouth movement and self-touching than those carried by non-smokers.

Foetuses usually move their mouths and touch themselves less as they gain more control the closer they get to birth.

The pilot study, which Dr Reissland hopes to expand with a bigger sample, indicated that babies carried by smokers may have delayed development of the central nervous system.

The research, conducted by Durham and Lancaster University, is published in the journal Acta Paediatrica.

Dr Reissland, from Durham's Psychology Department, said: "A larger study is needed to confirm these results and to investigate specific effects, including the interaction of maternal stress and smoking."

She believed that videos of the difference in pre-birth development could help mothers give up smoking.

But she was against demonising mothers and called for more support for them to give up. Currently, 12% of pregnant women in the UK smoke but the rate is over 20% in the Durham, Darlington and Tees area.

All the babies in her study were born healthy, and were of normal size and weight.

Dr Reissland, who has an expertise in studying foetal development, thanked the mothers who took part in her study, especially those who smoked.
