[Risk factors for the occurrence of cardiovascular system diseases in students]

Cardiovascular diseases are a leading cause of death in the majority of developed, as well as in many developing countries. The aim of this study was to determine cardiovascular risk factors in student population and to suggest possible measures for prevention.

The study was carried out during 2007-2008 at the School of Medicine, University of Nis. It included 824 students in their final year (220 males, 604 females).

There was no significant difference in prevalence of hypertension among the male (1.81%) and female students (0%). The prevalence of obesity (Body Mass Index - BMI > 30 kg/m2) was significantly higher (p < 0.001) in the male (7.27%) than in the female population (1.32%). Abdominal obesity was also more frequently encountered (p < 0.01) in the male (9.09%) than in female population (1.32%). Every fourth student smoked cigarettes with no significant difference between the male and female students. Alcohol consumption was a significantly higher problem (p < 0.001) in the male population (18.18%) than in the female one (2.65%). Physical inactivity was more often found (p < 0.001) in the female students (65.56%), than in male ones (36.36%). By the bivariate correlation of cardiovascular risk factors, it was determined that in the male student population systolic blood pressure correlated significantly with diastolic blood pressure, BMI and waist size, whereas age correlated with sistolic blood pressure, waist size and smoking. In the female students sistolic blood pressure correlated with diastolic blood pressure, BMI and waist size; diastolic blood pressure correlated with BMI and physical inactivity; cigarette smoking correlated with alcohol consumption and age.

Cardiovascular risk factors are present in the final-year students of the School of Medicine, University of Nis. It is necessary to insist on decreasing obesity prevalence, cigarette and alcohol consumption, and on increasing physical activity of students in order to prevent cardiovascular diseases.
