AIM: To study the frequency of borderline @entity146 in @entity1 of secondary general education schools. MATERIAL AND METHODS: We examined 1013 male and female schoolchildren, aged 12-14 and 15-17 years. In the first stage, the they completed a screening questionnaire to estimate the presence of a range of @entity5539 . An analysis of medical history and clinical examination were performed as well. The second stage included medical examination using DAWBA for the @entity1 with total scores on The Strengths and Difficulty questionnaire >= 16; with the score >= 6 on the emotional scale and with the score  <=5 on the social scale. RESULTS AND CONCLUSION: Generalized anxiety and @entity308 were recorded more often in @entity1 than in @entity1 . Every 4-th adolescent (26.1%), regardless of gender, had problems in communication with peers. At the same time, @entity1 showed conduct disturbances more often (p=0.005) than @entity1 (23.3% and 16.3%, respectively). @entity308 was 6,1 times more frequent in adolescents of the older group as compared with younger @entity1 (  =0.024). @entity308 was associated with @entity2794 (68.6% of @entity1 , mostly in @entity1 and in the older group), @entity490 (37.3%, mostly in @entity1 ) and back pain (39.2%).
