Researchers, psychologists and others in the medical field have known for years that genes play an important role in how soon teens begin to engage in sexual activity.
Genes determine when a teenager reaches puberty, and this is a strong factor for what is known as studying ‘At First Sex’ (AFS).
However, a recent study showed that in low-income families experiencing stress, environmental factors will be an even stronger determinant as to when they begin having sex.
A comparison of adolescents from low-income families and more affluent families showed a remarkable difference between the two.
Adolescents from more socio-economic advantaged families were much more influenced by genes when it came to AFS.
Teenagers from low socio-economic status and ethnic-minority families were more influenced by their environment, said the study done at University of Texas in Austin.
