Getting a good education could be the best form of contraception for teenagers, according to a new study.
British researchers found that greater use of contraceptive implants and drugs had an almost statistically insignificant effect on the teenage pregnancy rate. But there was a much stronger link between better exam result and teenage births.
A paper called Is Education the Best Contraception? The Case of Teenage Pregnancy in England, published in Social Science and Medicine, said: "Educational performance is significantly associated with lower teenage pregnancies and the estimated effects are large. For example, a 10 per cent increase in GCSE [end of school results] implies a reduction in the teenage conception rate of about 8 per cent."
Figures released last month showed the pregnancy rate for under-18s in England - although still among the highest in the west - has fallen by more than 40 per cent.
"Given that the numbers achieving five good GCSEs have increased by about 50 per cent since 2004, this factor alone has the potential to explain a large proportion of the recent decrease," the paper said.
