REPRODUCIBILITY AND PREDICTIVE VALUES OF ROUTINE BLOOD PRESSURE MEASUREMENTS IN CHILDREN COMPARISON WITH ADULT VALUES AND IMPLICATIONS FOR SCREENING CHILDREN FOR ELEVATED BLOOD PRESSURE

摘要: A study of the variability blood pressure was conducted among a total 780 Massachusetts children, 335 children in East Boston and 445 Brookline, ages 8-18 years. All had their measured with standard mercury sphygmomanometer school setting on four visits one week apart three measurements per visit. In Boston, repeat were made for same consecutive nested random effects model used to estimate between- within-visit variance components. For aged 8-12 years, these were, respectively, 33.1, 12.0 boys 31.2, 11.1 girls systolic 57.7, 21.3 56.6, 22.6 muffling (Korotkoff phase 4). 13-18 years age, they 41.1, 11.8 35.2, 12.2 40.6, 15.5 36.1, 11.4 diastolic 5). Within-person comparable previously published data 434 white adults 30-49 not antihypertensive medications; however, within-person considerably higher accounting over 75% 8-12-year-old compared 27% adults. No meaningful sex, or level found. However, age each large independent inverse association pressure; components younger (ages years) low (less than 60 mmHg) approximately twice as older greater equal mmHg, respectively. Finally, predictive value estimates are provided particular age-sex groups enable efficiently identify whose true mean exceeds 90th percentile group minimum misclassification. Because substantial young resulting relatively estimates, (either alone combination pressure) may be more useful primary tool screening under 13 high pressure.
