Resting blood pressures were recorded for children in the Dunedin Multidisciplinary Health and Development Study at two year intervals five times from age seven to fifteen. Correlations between pairs of readings were modest but significant, and higher for systolic (0.39 to 0.62) than for diastolic blood pressure. However, although children with normal blood pressure were likely to continue to have normal blood pressure, high blood pressures at age seven, nine, eleven and thirteen were not stable--only 28% of those whose systolic blood pressure at age seven was in the highest 5% had two subsequent readings in the highest 5%. On the other hand 56% of those in the highest 20% had two subsequent readings in the highest 20%, and 9% had all subsequent readings in the highest 20%. We do not believe that adult essential hypertensives can be recognised early by annual blood pressure measurement in childhood and the assignation of blood pressure rank according to a set of normal values.
在达尼丁多学科健康与发展研究中，从7岁到15岁期间，每隔两年为儿童测量一次静息血压，共测量了5次。每次测量结果之间的相关性虽不高但显著，收缩压的相关性（0.39至0.62）高于舒张压。然而，尽管血压正常的儿童可能会继续保持正常血压，但7岁、9岁、11岁和13岁时的高血压并不稳定——7岁时收缩压处于最高5%的儿童中，只有28%在随后的两次测量中仍处于最高5%。另一方面，处于最高20%的儿童中，56%在随后的两次测量中仍处于最高20%，9%在所有后续测量中都处于最高20%。我们认为，通过儿童期每年测量血压并根据一组正常值确定血压等级，无法早期识别出成年原发性高血压患者。
