Early diagnosis of hypertension (HT) is an important strategy in its control. Tracking of blood pressure (BP) has been found useful in identifying persons with potential HT, particularly in youngsters. A cohort of 756 subjects (with baseline information as a cross-sectional study in 2002) was followed up in 2006 to comment on the distribution of BP and its attributes.
To track BP distribution in a cohort of adolescents and young adults, and assess the persistence of high/low normotensives; to measure the incidence of HT and study the relationship of BP with age, sex, socioeconomic status, BMI, physical exercise, salt intake, smoking and alcohol consumption.
The baseline study cohort (2002) of 756 subjects (19-24 years) in urban field area of Department of Preventive and Social Medicine, JIPMER, was followed up between May and November 2006 by house visits for measurement of sociodemographic variables, anthropometry, salt intake, physical activity and BP.
A total of 555 subjects from the 2002 cohort were contacted (73.4%), in that 54.5% subjects who were below 5(th) percentile, 93.6% subjects between 5(th) and 95(th) percentiles and 72% of those above 95(th) percentile previously persisted in the same cut-offs for systolic blood pressure (SBP). The corresponding figures for diastolic blood pressure (DBP) were 46.2, 92.2 and 74.1%, respectively. Shift from one cut-off to another was not significant for both SBP and DBP, proving the tracking phenomenon. Annual incidence of HT was 9.8/1000. Baseline BP was the significant predictor of current BP for the entire cohort; BMI and salt intake were significant predictors only in certain sections of the study cohort.
Early diagnosis of hypertension even among adolescents/young adults is an important preventive measure, as tracking exists in the population.
高血压（HT）的早期诊断是其控制的一项重要策略。血压（BP）追踪已被发现有助于识别潜在高血压患者，尤其是在年轻人中。对一组756名受试者（2002年作为横断面研究有基线信息）在2006年进行了随访，以评价血压分布及其特征。
追踪青少年和青年人群的血压分布，评估正常血压者血压高/低的持续性；测量高血压发病率，并研究血压与年龄、性别、社会经济状况、体重指数、体育锻炼、盐摄入量、吸烟和饮酒的关系。
2006年5月至11月，对位于印度 Pondicherry 的 Jawaharlal 医学研究生院预防与社会医学系城市地区的756名受试者（19 - 24岁）的基线研究队列（2002年）进行了随访，通过家访测量社会人口统计学变量、人体测量学指标、盐摄入量、身体活动和血压。
2002年队列中的555名受试者（73.4%）被联系到，其中收缩压（SBP）处于第5百分位数以下的受试者中有54.5%、处于第5至第95百分位数之间的受试者中有93.6%以及处于第95百分位数以上的受试者中有72%在之前的收缩压临界值范围内保持不变。舒张压（DBP）的相应数字分别为46.2%、92.2%和74.1%。收缩压和舒张压从一个临界值范围转变到另一个临界值范围并不显著，证实了血压追踪现象。高血压的年发病率为9.8/1000。基线血压是整个队列当前血压的显著预测指标；体重指数和盐摄入量仅在研究队列的某些部分是显著预测指标。
即使在青少年/青年人群中，高血压的早期诊断也是一项重要的预防措施，因为人群中存在血压追踪现象。
