Abstract
Repeated blood pressure measurements in 127 diabetic children, obtained at intervals of 6 mo., were studied. Tracking of measurements described by the correlation between repeated observations of systolic blood pressure showed the highest degree of tracking between consecutive measurements (0.38-0.76), while there was a lower degree of tracking between measurements at longer time intervals, and lower degree of tracking in the observations of diastolic blood pressure than of systolic blood pressure. After adjustment for changes in height and weight, the tracking correlations are slightly smaller on the whole. The tracking correlations are generally rather small and repeated measurements of blood pressure are necessary. [The association between diabetes and hypertension is discussed.].
