As per the recent report published in Lancet Child & Adolescent Health journal, the scientists say it's vital to change the definition of adolescence keeping in mind the stretch in the education and delayed marriage and parenthood which has changed the age-old perception of when the adulthood begins. They say it is essential in order to ensure laws and government policies remains appropriate however there are experts who put light on this step “further infantilizing young people”.
The conventional age slab for the adolescence was from fourteen to nineteen years the scientific logic behind this was the fact that approximately at the age of 14 years hypothalamus begins to release the hormone which stimulates the pituitary and gonadal glands. This starts even earlier in the developed countries at around the age of 10 years, better health facilities and nutritious diet could be the reason responsible for this early onset of puberty.
Also, the argument that supports the extension of the adolescence age slab is the continued development of brain and body.
As per the reports of OFFICE OF NATIONAL STATISTICS, the average age for a man to enter their first marriage in 2013 was 32.5 years and 30.6 years for women across England and Wales.which reflects the increase of eight years since 1973 report.
This social change will impact the existing laws and policy across the globe if implemented. Like the policy of youth support services and other laws pertaining to the welfare and development of the adolescents.
