According to a recent study, early puberty increases the risk of addiction to alcohol and drugs, especially among young white Americans.
According to a published US study, there is a correlation between precocious puberty and the risk of addiction in boys. Researchers at the Universities of Pittsburg and Purdue in the United States explain this by the effects of testosterone on the brain of adolescents. Young white Americans are particularly concerned.
Their work, published in the journal Child Development, is the result of a study of the data of 530 boys followed by the North American Institute of Drugs between 1989 and 2000. At the beginning of the study, the subjects were 11 years old. Their consumption of alcohol, tobacco and drugs, including prescription drugs, has been controlled from 16 to 30 years. In parallel, blood samples were taken at 11, 13 and 16 to measure their hormonal development.
The researchers found that early adolescents had higher testosterone levels and addiction risk than others. This correlation between addiction and testosterone is particularly significant among young white Americans. Social pressure, exacerbated by testosterone, is responsible for these addictive substances.
Kristine Marceau hopes that this study will lead to the development of new prevention strategies. She insists that these results are not irreversible and that education and monitoring of adolescents is essential to limit the opportunities to consume addictive products.
