Key result
Six-hour ambulatory blood pressure monitoring correlated significantly with full daytime monitoring in children (CCCs 0.86-0.98), with mean differences ranging from -1.1 to 1.3 mm Hg.
Why the study?
Does 6-hour interval ambulatory blood pressure monitoring correlate with full daytime monitoring in pediatric patients?
Observational (n=131)
Does 6-hour interval ambulatory blood pressure monitoring correlate with full daytime monitoring in pediatric patients?
Shorter 6-hour interval ambulatory blood pressure monitoring correlates significantly with full daytime monitoring in children, offering a more convenient assessment method.

Shorter-interval (6-hour) ambulatory blood pressure monitoring (ABPM) has been shown to correlate well with 24-hour ABPM in adults, but this has not been studied in children. The authors selected 131 patients aged 9 to 18 who underwent 24-ABPM from 2000-2008. Six-hour intervals beginning at different start times were compared with the daytime and 24-hour period, with subset analysis for normotensive and hypertensive patients. Concordance correlation coefficients (CCCs) were used to assess for agreement. Among normotensive patients, the mean difference between daytime and 6-hour intervals ranged from -0.1 mm Hg to 0.0 mm Hg for diastolic blood pressure (DBP) and -1.1 mm Hg to 0.6 mm Hg for systolic blood pressure (SBP) with CCCs of 0.88 to 0.93 for DBP and 0.93 to 0.96 for SBP. For hypertensive patients, mean difference ranged from -0.6 to 1.3 mm Hg for DBP and -0.8 to 1.1 mm Hg for SBP with CCCs of 0.89 to 0.98 for DBP and 0.86 to 0.95 for SBP. Shorter-interval monitoring correlates significantly with full daytime monitoring in children, allowing for assessment of blood pressure with improved convenience.

King‐Schultz et al. (2012) conducted an observational in Hypertension (n=131). 6-hour interval ambulatory blood pressure monitoring vs. Daytime and 24-hour ambulatory blood pressure monitoring was evaluated on Agreement between 6-hour intervals and daytime/24-hour periods assessed by concordance correlation coefficients (CCCs) and mean differences. Six-hour ambulatory blood pressure monitoring correlated significantly with full daytime monitoring in children (CCCs 0.86-0.98), with mean differences ranging from -1.1 to 1.3 mm Hg.
