The method of classification and regression trees (CART) has been applied to define the factors influencing BMI. Our results have been compared with WHO standarts, valid also for EU. The research objects have been 275 students from 5th, 6th, 7th, and 8th grade from secondary schools in Plovdiv. Results: The share of those who have breakfast in the morning (50,2 %) was almost the same as those who had more than two main meals per day (53,8 %). From all respondents, almost a quarter was not interested in sports, which was also confirmed by the fact that (39,3 %) of the respondents did not practice sports after school. The BMI estimation (according to the WHO standards) provided the following results: (60 %) of the adolescents had normal weights, and (38,5 %) had weight over the norm. Conclusion: Unhealthy and not -balanced nutrition habits were found at almost half of the examined students. This nutrition was accompanied by insufficient physical activity -the share of 11-12 years old students with overweight is bigger than those of 13-14 years old.
