New York, Nov 3 (IANS): Talking about the birds and the bees with your adolescent kids can protect them against risky sexual behaviour, suggests new research.

Parent-adolescent sexual communication is associated with greater use of condoms and contraceptives, the findings showed.

The researchers found that the association was stronger for girls who discussed sexual topics with their mothers.

Risky sexual behaviour among adolescents is a serious public health problem because of the risk of sexually transmitted infections and unintended pregnancies.

"Results of this study confirm that parent-adolescent sexual communication is a protective factor for youth, and a focus on communication remains justified in future intervention efforts," the researchers said.

However, such open communication about sex does not always take place because embarrassment and inaccurate knowledge can get in the way.

Laura Widman from North Carolina State University in the US, and co-authors reviewed medical literature and pooled data from 30 years of research with more than 25,000 adolescents from 52 articles to examine the effect of parent-adolescent sexual communication on safer sex behaviour among youth.

The researchers found significant positive effect of parent-adolescent sexual communication associated with safer sex behaviour.

The association between parent communication and adolescents' contraceptive and condom use was significantly stronger for girls than boys, the findings showed.

The study was published online in the journal JAMA Pediatrics.
