Onset, Pace of Puberty Tied to Behavior Problems

Onset, Pace of Puberty Tied to Behavior Problems A provocative new research reports suggests that children who speed through puberty are more likely to act out and to suffer from anxiety and depression.

Researchers at Penn State, Duke University and the University of California, Davis believe their findings can serve as a screen to mitigate future behavioral problems.

The results suggest that primary care providers, teachers and parents should look not only at the timing of puberty in relation to kids’ behavior problems, but also at the tempo of puberty — how fast or slow kids go through puberty.

“Past work has examined the timing of puberty and shown the negative consequences of entering puberty at an early age, but there has been little work done to investigate the effects of tempo,” said Kristine Marceau, the study’s primary author and a doctoral student at Penn State.

“By using a novel statistical tool to simultaneously model the timing and tempo of puberty in children, we present a much more comprehensive picture of what happens during adolescence and why behavior problems may ensue as a result of going through these changes.”

Researchers created a statistical model that used data from 364 white boys and 373 white girls that had been collected as part of the National Institute of Child Health and Human Development’s Study of Early Child Care and Youth Development.

The data included information about breast and pubic hair development in girls and genital and pubic hair development in boys as assessed by nurses, as well as weight and height for both boys and girls.

The data also included information on internalizing and externalizing behavior problems as reported by boys’ and girls’ parents or other caregivers, and risky sexual behaviors as reported by the kids themselves.

“We found that earlier timing for girls was related to a slew of behavior problems, and we also found that a faster tempo of development independently predicted those same sorts of problem behaviors,” said Marceau.

“Although timing and tempo both predicted behavior problems in girls, timing and tempo weren’t related to each other. For boys, though, we found a strong relationship between timing and tempo.

“For example, we found that boys who have later timing combined with slower tempo exhibited the least amount of acting out and externalizing problems.”

The team’s results will appear in the September issue of the journal Developmental Psychology.

Why does going through puberty at a faster rate relate to external behavior problems and internal anxiety and depression?

“The thought is that when the major changes of puberty are compressed into a shorter amount of time, adolescents don’t have enough time to acclimate, so they’re not emotionally or socially ready for all the changes that happen,” said Marceau.

“This is the explanation that originally was attributed solely to early timing, but we suggest that the same thing also is happening if the rate of puberty is compressed.”

According to the researchers, the timing and tempo of puberty vary dramatically across kids. Moreover, children are very knowledgeable and sensitive as to how fast or slow their friends are going through puberty.

This could influence both the internalizing depression-type problems and the externalizing problems of acting out, say the authors.

In the future, the researchers plan to examine the effects of tempo of puberty on later women’s health problems—particularly the relationship between early puberty and later women’s health problems.

One particular area they plan to investigate is the potential link between early puberty and reproductive cancers. Some believe the longer exposure to the hormone estradiol, associated with early puberty, can increase risks.

Another study focus surrounds the question of whether the tempo of puberty has implications for women’s health.
