Mothers who attend antenatal classes are far more likely to breastfeed their children, according to research released Wednesday.

A study by the University of Edinburgh found three-quarters of mothers who attended all or most of their antenatal classes breast fed their child. This compared with half of mothers who did not attend classes.

The study was carried out by the university's Centre for Research on Families and Relationships (CRFR). More than 8,000 mothers of young children in Scotland were interviewed for the research, which is based on the Growing Up In Scotland survey.

Previous research has shown that age and educational background are linked to breastfeeding figures. This study found 86 per cent of mothers with degrees breast fed, compared with 31 per cent of mothers with no qualifications. It also showed antenatal classes tripled the chances of breastfeeding, regardless of these factors.

Valeria Skafida, the researcher who led the study, said: "This research shows that having access to accurate information is crucial in a mother's decision to breastfeed and that antenatal classes make a big difference in giving children the best start in life.

"More research is needed to understand how take-up can be increased in groups that are under-represented."

Studies have shown that babies who are breast fed are less likely to be obese in later life and gain protection against conditions like asthma, eczema and chest infections.

Mothers benefit too, with studies showing a protective effect against ovarian and breast cancer.

A national breastfeeding helpline to support new mothers was officially launched by the Government earlier this month. The number is 0844 209 0920.
