Adolescent girls (up to 19 years)
More obvious differences appear between girls and boys in the age of 10-19 years. The girls become more different in their makeup and behavior in comparison to boys. The health risks become also more distinct. Accident injuries usually from road traffic are the leading cause of death among adolescent girls (10–19 years) in developed and developing countries. Suicide and mental health disorders such as depression among youngsters or schizophrenia make the ill-health and death rate higher worldwide. Adolescent girls are at more risk than boys of unsafe and often unwanted and forced sexual intercourse that can lead to HIV/AIDS, sexually transmitted infections, thus unwanted pregnancy and unsafe abortion. Pregnancy-related complications which cause death among adolescent girls are the other risk factors for girls in the age up to 19 years. Nowadays much more girls just like boys in their 16-19 years abuse tobacco and alcohol. More and more cases are reported of illegal drug usage. These factors lead to changes in general health and have a great negative impact on later life, as well as poor diet and physical inactivity.
