Abstract

Abstract : Objective: Measurement of blood pressure and diagnosis of hypertension in children and adolescents can be challenging. This is due to several factors such as conditions by which measurement takes place, the white coat effect but also increased physical activity during the day. This study assessed the correlation of clinic measurements to daytime ambulatory BP measurements in children that were examined in the hypertension clinic of a tertiary hospital. Design and method: We examined 43 consecutive children. At baseline we measured office blood pressure according to international guidelines. Within 15 days from the first visit the subjects underwent ambulatory blood pressure measurement using the Spacelabs OnTrak device on child mode. 15 of these children were diagnosed with secondary hypertension at follow up. Results: The mean age of the population was 11 ± 2.95 years. Clinic systolic blood pressure (SBP) showed no significant correlation with ambulatory daytime SBP (r = 0.279, p = 0.11). The same was the case for the correlation of clinic diastolic blood pressure (DBP) to daytime ambulatory DBP (r = 0.108, p = 0.54). Mean values of clinic SBP were comparable to daytime ambulatory SBP (120.6 ± 13.4 vs 122.9 ± 9.9mmHg for clinic and ambulatory respectively). Clinic DBP also showed no significant difference compared with daytime ambulatory DBP (75.8 ± 11.7 vs 74.9 ± 5.6mmHg for clinic and ambulatory respectively). Conclusions: Phenotypes in hypertension in children follow a different pattern than those in adults. Correlation between clinic and ambulatory measurements while not linearly correlated their mean values show no significant differences. One method should not exclude the other, rather they should be complementary.
