This study compared the long-term reproducibility of home blood pressure
(BP) in comparison with office BP in children and adolescents.
Forty-eight subjects (27 boys, mean age 11.3 +/- 3.1 (s.d.) years)
recruited from the Arsakeion school study because of elevated office
and/or home BP were assessed with office (1 visit, mercury
sphygmomanometer) and home BP measurements (3 days, electronic devices)
in two assessments 17 +/- 4.9 months apart (range 10-26 months). Home
and office BP were compared on the basis of the following criteria: (a)
s.d. of mean BP; (b) s.d. of differences; (c) variation coefficient
(CV); (d) concordance correlation coefficient (CCC); (e) test-retest
correlations; (f) correlation with ambulatory BP. (a) The s.d. of mean
home BP was lower than that of office BP in both the initial (home BP
9.1/7.1 mm Hg, systolic/diastolic; office BP 13.1/8.0 mm Hg) and the
second assessment (9.2/6.0 and 14.9/11.5 respectively). (b) The s.d. of
differences was lower for home BP (8.3/6.5 mm Hg, systolic/diastolic)
than for office BP (13.9/10.7 mm Hg). (c) The CV of home BP (5.3/6.6,
systolic/diastolic) was lower than that of office BP (8.2/10.9). (d) The
CCC of home BP (0.54/0.50, systolic/diastolic) was higher than that of
office BP (0.51/0.41). (e) Test-retest correlations were closer for home
BP (r=0.58/0.52, systolic/diastolic) than for office BP (0.51/0.44). (f)
Awake ambulatory BP was more closely associated with home (r=0.77/0.40,
systolic/diastolic) than with office BP (0.65/0.24). These data suggest
that in children and adolescents the long-term reproducibility of home
BP is superior to that of office measurements.
