Background: Contrary to numerous studies on noise and blood pressure in adults, similar investigations in children and adolescents are still scarce and equivocal. The aim of this study was to investigate the relationship between exposure to noise at school and at home and childrenís resting blood pressure. Methods: A cross sectional study was performed on 467 children and adolescents (203 boys and 264 girls) aged 11-15 years, from six elementary schools in Belgrade. A medical doctor measured childrenís resting blood pressure with sphygmomanometer in a school setting. Body mass index for age percentile (BMI) was calculated after measurement of body mass and height. Noise was measured in front of childrenís residences in one evening interval and in two night intervals (Leq home), and in front of each school in three daily periods (Leq school). Results: Multiple regression analysis, after allowing for age, gender and BMI, revealed a significant positive relation between Leq school and childrenís systolic pressure. A 4,5 mm Hg rise of blood pressure may be expected per 10 dB increase of Leq school (B=0.447; 95% CI = 0.261-0.633; p < 0.001). Conclusion: Increased noise levels at school might be related to a higher systolic pressure in children and adolescents.
