Boys Hit Puberty Sooner Now, Study Finds

American boys are entering puberty at a younger age than they did several decades ago, according to new research. But the study – which mirrors previous research about girls and puberty – does not pinpoint what’s causing the change.

Investigators at the University of North Carolina School of Public Health in Chapel Hill found that boys are showing the first signs of sexual maturity six months to two years earlier, with blacks having a significant head start relative to whites and Hispanics.

Commenting on the study, Dr. Frank Biro, director of adolescent medicine at Cincinnati Children’s, agrees that the growing gap between physical and social maturation should be viewed with concern. But Biro adds he isn’t sure that an earlier maturing boy is going to be sexually active any earlier.

“I do think that it may lead to a little greater disparity between social maturation and physical maturation. And that is certainly something to think about,” explains Dr. Biro.

    It would be interesting to see if there is a correlation between life style, in particular the high incidence of a processed foods, and this emerging data.
