WEDNESDAY, Oct. 9 (HealthDay News) -- Teens who began puberty at
an early age are more likely to experiment with cigarettes, alcohol
and marijuana, researchers report.
The study included nearly 6,500 boys and girls, aged 11 to 17,
who were asked about their substance use in the past three months.
The participants also completed a questionnaire designed to
determine when they began puberty.
The findings were published in the October issue of the journal

national estimates of puberty onset. For example, girls report
developing earlier than boys and nonwhites report developing
earlier than whites.
"We all go through puberty. We remember it being either an easy transition or a very difficult one," study author Jessica Duncan Cance, a public health researcher at the University of Texas at Austin, said in a university news release.
Cance noted that much research has been devoted to the
psychological and social factors that increase teens' risk of
substance use, but relatively little is known about how the timing
of the start of puberty could play a role.
"While puberty is often thought of as a solely biological process, our research has shown that pubertal development is a combination of biological, psychological and social processes that all likely interact to influence risk-taking behavior like substance use," Cance said.
"Our study suggests that being the first girl in the class to need a bra, for example, prompts or exacerbates existing psychological and social aspects that can, in turn, lead to substance use and other risky behaviors early in life," she explained.

and higher risk for substance use, it did not establish a
