To determine, in a school-based sample of children and adolescents, aged from 7 to 17 years, of both gender, in public and private schools, the frequency of students already submitted to blood pressure measure.
A cross-sectional study was carried out, sampling from a population pool of elementary and middle schools, randomly selected. The sample was calculated based on the expected prevalence of hypertension for the age group. Data were collected through a questionnaire. Blood pressure was measured twice and hypertension was defined as mean systolic and/or diastolic blood pressure over the 95th percentile. Independent variables studied: sex; age groups; economic status; public/private school.
The final sample included 1253 students. The response rate was 97%: 1215 students; 531 males; mean age 12,4 +/- 3 years (236 from 7 to 9 years; 638 from 10 to 14 years; 341 from 15 to 17 years). Prevalence of hypertension was 7.7%; 348 students (29%) were already submitted to blood pressure measures (54% once; 35% 2 to 4 times; 11% 5 or more times). High economic status, private school and adolescent group were significantly associated to previous blood pressure measure.
Despite of pediatric consensus statements and guidelines recommendations about importance of blood pressure measure at every examination after age 3 years, there is a very low frequency of this practice (29%) in children and adolescents.
在公立和私立学校中，以7至17岁的儿童和青少年为样本，确定已接受血压测量的学生的频率。
开展一项横断面研究，从小学和初中的总体人群中随机抽样。样本根据该年龄组高血压的预期患病率计算得出。通过问卷收集数据。血压测量两次，高血压定义为平均收缩压和/或舒张压超过第95百分位数。研究的自变量：性别；年龄组；经济状况；公立/私立学校。
最终样本包括1253名学生。应答率为97%：1215名学生；531名男性；平均年龄12.4±3岁（236名7至9岁；638名10至14岁；341名15至17岁）。高血压患病率为7.7%；348名学生（29%）已接受血压测量（54%测量过一次；35%测量过2至4次；11%测量过5次或更多次）。高经济状况、私立学校和青少年组与之前的血压测量显著相关。
尽管儿科共识声明和指南建议3岁后每次检查时测量血压很重要，但儿童和青少年中这种做法的频率非常低（29%）。
