British mums-to-be are among the most likely in the world to drink during pregnancy and harm their unborn baby as a result, new research finds.

The study, conducted by the Canadian Institute of Mental Health Policy and Research, found that four times more children in the UK suffer alchohol-related birth defects than the global average.

For the proportion of children with foetal alcohol spectrum disorder (FASD), Britain came seventh out of 195 countries and sixth in Europe.

As such, the Canadian scientists have called for the dangers of alcohol to be reinforced in sex education and suggest that screening pregnant women for alcohol could help to combat the problem.

The study’s author, Dr Svetlana Popova, said the issue should be considered “a public health priority”.

The research also found that one in every 13 women who drink during pregnancy will go on to have a child with FASD, which is caused when alcohol drunk by the mother passes through the placenta to the foetus. As an unborn child is unable to process alcohol, it damages their cells.

Symptoms of FASD include learning difficulties, issues with hearing and vision, cerebral palsy, and problems with the liver, kidneys and heart.

This was my biggest fear both times while pregnant and it made me so anxious," says Megan Porter who lives in Falkirk.

After analysing 24 global studies, the scientists discovered that 32 in every 1,000 Britons have FASD, compared to the global average of eight in 1,000.

In comparison, the figure is 15 in 1,000 in the US, 10 in France and 20 in Germany.

Meanwhile, South Africa was found to have the highest proportion of people with FASD, with 111 in 1,000.

With many mothers blaming binge-drinking in the first few months when they do not realise they are expecting, doctors say that abstaining at any point is better than not at all.

“If you would strap a child into a car seat to protect them in case you might have an accident, this is no difference,” said Sandra Butcher, of the National Organisation for Foetal Alcohol Syndrome UK.
