The aim of this study was to analyze the influence of the number of visits and the number of blood pressure (BP) measurements on the prevalence of high blood pressure (HBP) in adolescents. A cross-sectional epidemiologic study with 481 adolescents (14-19 years old) selected using a random cluster sampling strategy. We measured the BP three times in a first visit. Adolescents with HBP performed subsequent visits. The final calculation of BP followed four strategies: the 1st measure, mean of 1st and 2nd measurements, mean of all three measurements, and averaging the 2nd and 3rd measurements. The prevalence of HBP in the first and second visits was 6.4% and 1.9%, and the prevalence of hypertension (after three visits) was 1.7%. The prevalence of HBP varied from 8.6%-18.6% for boys and 4.6%-9.2% for girls, using the average 2nd and 3rd measurements and the 1st measurement, respectively. In all strategies, HBP and hypertension were more prevalent in boys and students attending the nocturnal shift. The number of visits and number of measurements affect the prevalence of HBP and hypertension in adolescents. Thus, clinicians and researchers should consider these aspects when assessing BP in adolescents aged 14-19 years old.
本研究旨在分析就诊次数和血压(BP)测量次数对青少年高血压(HBP)患病率的影响。采用随机整群抽样策略选取了481名青少年(14 - 19岁)进行横断面流行病学研究。我们在首次就诊时测量了三次血压。患有HBP的青少年进行了后续就诊。血压的最终计算采用了四种策略:第一次测量值、第一次和第二次测量值的平均值、三次测量值的平均值以及第二次和第三次测量值的平均值。首次和第二次就诊时HBP的患病率分别为6.4%和1.9%,三次就诊后高血压的患病率为1.7%。分别使用第二次和第三次测量值的平均值以及第一次测量值时,男孩HBP的患病率在8.6% - 18.6%之间,女孩在4.6% - 9.2%之间。在所有策略中,HBP和高血压在男孩以及上夜班的学生中更为普遍。就诊次数和测量次数会影响青少年HBP和高血压的患病率。因此,临床医生和研究人员在评估14 - 19岁青少年的血压时应考虑这些因素。
