Abstract

Introduction. A World Health Organization (WHO) conference on a “second wave” epidemic of cardiovascular diseases, directly linked to arterial sclerosis (AS), predicts that in 2020 cardiovascular diseases will most likely be the leading cause of death in the world. The development of AS begins in youth and progresses with age. It’s intensity depends on the risk factors involved, such as: smoking, hypertension, obesity and fat and sugar disorders in the body. Aim. The aim of this study was to establish the risk factors of cardiovascular diseases and their existence, among the youth of the upper gymnasium school. Material and methods. The research was conducted using 511 volunteer students from upper and lower gymnasium schools, between 16-19 years of age. Our research methods included: a diagnostic questionnaire, the measurement of blood pressure (BP) and anthropometric measurements. In the statistical study, we used chi-square independence testing, the V-Kramer test and the tau-b Kendall test; the level of changes α = 0.05 – was used. Results. Over a half of the study group (52.5%) was characterised with the lack of recommended physical activity, much more common in girls than boys (p = 0.000), just like smoking (p = 0.009) which was declared by 39.7% of the interviewed youth. In turn, a heightened value of systolic and diastolic pressure occurred more often in boys (19.6%) than in girls (12.1%); (p = 0.000 vs. p = 0.003). Excessive body mass was noted in 15.7% of the respondents, also more often in boys than in girls (p = 0.02), and abdominal obesity occurred in 10.2% of the respondents, with no significant differences between the sexes. 42.3% of the respondents showed one, 29.9% showed two and 18.8% showed three atherosclerosis risk factors. 9.0% of the study group showed 4 and more such risk factors. Accumulation of atherosclerosis risk factors occurred significantly more often in girls than in boys (p = 0.002). Conclusions. In all the respondents at least one atherosclerosis risk factor was found, and in over half of the study group, more frequently in girls than in boys, an accumulation of two or more risk factors was observed. Lack of recommended physical activity was the most frequent atherosclerosis risk factor occurring in the youth.
