abstract
- The objective of this study was to determine the interrater variability and effect of state on systolic blood pressure measurements in infants 36 weeks' gestational age, the former had a systolic blood pressure 13.0 +/- 14 mm Hg greater than the 50th centile for age and gender versus 2.4 +/- 12 mmHg for those >36 weeks' gestation. In study 2, the interclass correlation coefficient for repeated measurements by a single rater was 0.85, and noncalm state at both measurements was associated with an elevated systolic blood pressure.Systolic blood pressure can be accurately measured in the first 3 years after birth, but state modifies systolic blood pressure and must be determined at the time of measurement. Infants born at
