The objective of this study was to determine the prevalence of hypertension, overweight and obesity in Croatian adolescents. In this cross-sectional survey (the sub-study of the EH-UH study) 375 boys and 381 girls (mean age 15.9 ± 0.5 years) from four high schools  in the city of Koprivnica were enrolled. Blood pressure, body height and body weight were measured according to the current ESH/ESC guidelines. Data on life style were obtained from questionnaire. Average blood pressure values were higher in boys than in girls (117/74 mmHg vs. 111/69 mmHg; p < 0.001). Significantly higher blood pressure values were obtained in overweight children compared to those with normal weight (119/76 mmHg vs. 115/72 mmHg; p < 0.01). Prevalence of hypertension was 8.5% in the whole group being significantly higher in boys than in girls (11.2% vs. 5.8%; p = 0.0007). As expected, prevalence of hypertension was significantly higher in obese children than in those with normal weight (20.0% vs. 6.8%; p = 0.015). A significant correlation was found between body mass index and blood pressure (p = 0.0001). The overall prevalence of obesity was 3.54% (boys 2.2%; girls 4.9%). Our results confirmed positive relationship between overweight, obesity and hypertension starting from childhood pointing again the utmost importance of preventive measures beginning from early life.
