This school-based screening study assessed the prevalence of high blood pressure (BP) levels according to the European Society of Hypertension (ESH) 2016 guidelines. Moreover, risk factors for BP elevation, and the effect of geographic and seasonal factors on BP screening were investigated. BP and anthropometric measurements were obtained from 2832 children and adolescents, aged 6–18 years, during the period 2013–2016. Three BP measurements were performed using a mercury sphygmomanometer, and the mean of the last two was used for the analysis. Obesity was defined according to the International Obesity Task Force (IOTF) criteria. The prevalence of high–normal BP/hypertension and overweight/obesity was 3.7%/0.9%, and 22.9%/8.5%, respectively. The majority of the participants presenting high BP (≥90th percentile) were overweight or obese. Increased prevalence of high BP was observed during spring (5.5%) and winter (5%) compared with 2.5% in autumn (P<0.05). SBP z scores were higher in males, during spring and summer, and in urban areas. In conclusion, a low rate of high–normal and hypertensive BP levels was found despite the high prevalence of overweight and obesity. Overweight and obesity were associated with higher BP levels, but there was also a seasonal difference in the prevalence of high BP levels.

这项基于学校的筛查研究根据欧洲高血压学会（ESH）2016指南评估了高血压（BP）水平的患病率。此外，还研究了血压升高的危险因素，以及地理因素和季节因素对血压筛查的影响。在2013-2016年期间，从2832名6-18岁的儿童和青少年那里获得了BP和人体测量数据。使用水银血压计进行了3次BP测量，最后两次的平均值用于分析。肥胖症是根据国际肥胖症工作组（IOTF）的标准定义的。高正常血压/高血压和超重/肥胖的患病率分别为3.7％/ 0.9％和22.9％/ 8.5％。血压高（≥90％）的大多数参与者超重或肥胖。P <0.05）。男性，春季和夏季以及城市地区的SBP z分数均较高。结论是，尽管超重和肥胖的患病率很高，但正常人和高血压的血压水平却较低。超重和肥胖与较高的血压水平有关，但高血压水平的患病率也存在季节性差异。
