Adolescent SuicideIntentionally taking one's own life is called suicide. In recent years, American society has become concerned with this problem, especially teen suicide. The suicide rate among adolescents is not constant over a period of time; continues to change over time. In most cases, the suicide rate among boys is higher than that among girls. Different types of people in our society respond to this problem in different ways. Earlier this year, approximately 932 parents of adolescents completed a questionnaire containing 30 common psychological medical concerns of adolescence, of which suicide was one of the items. They were asked how important it is for pediatricians to talk about this with their children during check-ups. The result showed that more than 66% of parents surveyed said that 29 of the 30 points were important to discuss with their adolescent children. This survey showed that American parents are somewhat concerned about suicide among teenagers. This concern is widespread among American teenagers. In 1993, a national survey of adolescents was conducted on their knowledge of and attitudes toward youth suicide. The survey found that 60% of adolescents reported knowing another adolescent who had attempted suicide while 6% reported having attempted suicide. The above two examples indicate that it is very important for parents, counselors or different institutions to become aware of the reasons and symptoms of adolescent suicide and find out possible preventive procedures. Recently, an examination of suicide rates among black and white adolescents from 1986 to 1991 was conducted. It showed that the suicide rate among girls of all ethnicities remained stable. Furthermore, the rate of white boys had virtually stabilized; however, the rate for black and other minority boys increased significantly. Those increases were fastest in areas where suicide rates were historically low. This phenomenon indicates that there are various types of reasons for suicide, and different types of methods are also used to commit suicide. During the late 1970s and early 1980s in Oxford, the rate of self-poisoning and deliberate self-harm in female adolescents decreased, but increased again between 1986 and 1989. For male adolescents, self-poisoning with tranquilizers and minor sedatives it had decreased. , but paracetamol self-poisoning has increased over that period. In Zimbabwe, young women in the 1970s used poison as a method of suicide; however, self-immolation was used frequently in the mid-1980s. There are various types of reasons why teenagers commit suicide. Suicide in adolescents is sometimes linked to or related to vision therapy. It has been argued that an inadequate level of concentration or poor attention span of a patient is a common cause of academic, personality and behavioral disorders.
