l E recent pregnancy and subsequent birth of a girl of 10 years (see here ) is surprising and shows the advance of puberty has occurred in last decades in most European countries, and around two years. The best conditions of life, but also the influence of certain pollutants on the endocrine system may be responsible for this development. Several studies have found a link between precocious puberty and the use of pesticides in intensive farming and hormones in food and raising livestock. On the other hand, some childhood experiences, especially having to do with the kind of emotional bond established with parents, can influence the physiological mechanisms involved in the onset of puberty. From this point of view, precocious puberty may be determined by family stress, depression, divorce, family reconstitution, more common in Western society today that lead to the establishment of links of insecure attachment.
The earlier onset of pubertal changes have their influence on emotional and behavioral aspects. On the one hand, we meet children who still show a significant and psychological immaturity, however, have an advanced physical maturity, circumstances, several studies have considered an important risk factor for psychological and behavioral adjustment of adolescents , especially for girls. Therefore, many behaviors that until recently were those of youth and adolescents are becoming common in late childhood: Relations Home partner, consumer behavior, technology use, etc.
Although greater involvement in risky behaviors may be due in part to the fact that these children relate to other older, we now know that there are some brain mechanisms involved as decision-making depends largely on balance between two brain circuits or systems: the mesolimbic reward, which leads to the pursuit of pleasurable experiences, and the prefrontal cortex, which helps us plan our actions, calculate the risks and inhibit behavior deemed inappropriate. As explained here , precocious puberty promotes the imbalance between these brain systems placing the adolescent boy or girl in a situation of greater vulnerability that will lead to more impulsive and thoughtless behavior.
Therefore, for this young mother warning us about some of the risks these early puberties can bring partners, and makes more necessary than ever to carry out preventive policies aimed not only to adolescents, but to children and prepubertal girls. This prevention should include a real sex education, which can not remain pending in most English schools.
