Background

Obtaining reliable blood pressure (BP) values in children remains challenging. Multiple office blood pressure monitoring (mOBPM) consists in a software-calculated mean derived from 10 serial BP readings taken at 3-minute intervals using a validated automated oscillometric device (www.mobpm.com), automatically discarding outlier readings (<5^th and > 95^th percentile of measured values) and assessing variability by coefficient of variation (CV). This novel approach to BP measurement minimizes the risk of overestimating BP and thus the overdiagnosis of arterial hypertension related to the white-coat phenomenon.
Since the role of home BP monitoring and home-based mOBPM in the pediatric setting has yet to be established, the present study aimed to compare BP values obtained through office-based (with and without healthcare professionals) and home-based mOBPM.

Methods

Children were consecutively enrolled among patients attending our Pediatric Nephrology clinic. Participants underwent mOBPM under 3 different conditions:
1. in office in the presence of healthcare professionals;
2. in office in the absence of healthcare professionals;
3. at home.
Measurements were obtained using the same device within a 5-day frame. After excluding mOBPM with a CV >15%, results from the three settings were compared by mean of repeated-measures ANOVA.

Results

Forty children (22 females, 55%) with median age 12.6 years (IQR 9.7–16.3) and BMI 18.2 kg/m² (IQR 16.5–21.9) were enrolled. All participants completed mOBPM in the three different settings. Since all recordings showed a CV ≤15%, none were excluded from the analysis.
As shown in Table 1, BP values obtained with home-based mOBPM were consistently and significantly lower than those recorded with office-based mOBPM, both in the presence and in the absence of healthcare professionals.

Conclusion

Home-based mOBPM provides significantly lower BP values compared with office-based mOBPM in children. These findings suggest that home-based mOBPM may reduce the influence of the white-coat effect and could represent a valuable tool for improving BP assessment in the pediatric population.
