Suicides rate, especially among young people in Lithuania, is the highest in Europe.

The goal is to define and compare the peculiarities of suicide behavior among teenagers of different sex.

109 teenagers were researched in the age group of 14 to 17 (52 boys and 57 girls), they were treated in Kaunas University of Medicine Psychiatry Clinics Children – Teenagers Department after they had tried to commit a suicide. Medical documentation and authors' concluded structuralized questionnaire were used to evaluate anamnesis data.

More than one half of boys and girls tried to commit a suicide for the first time, the other part of researched teenagers attempted this repeatedly (46,2 % of boys and 42,1 % of girls). Researching suicide environment, the correlation between suicide surroundings and sex was established (χ2=9,21, lls=2, p=0,01). Three fourths (75,4 %) of girls chose parental home surroundings, whereas only every second boy chose the surroundings of parental home (51,9 %) (p<0,05). Quite the same percentage of researched boys and girls - accordingly - 17,3 % and 15,8 % percent chose school and friend environment; the percentage of boys who chose other environment (remote places) was triple larger than the percentage of the girls in this group - accordingly 30,8 % and 8,8 % (p<0,01).

research data suggests that suicidal behavior of teenage boys and girls implies statistically significant differences.
