Comparison of blood pressure levels among four age groups of Chinese children matched by height.
Summary of "Comparison of blood pressure levels among four age groups of Chinese children matched by height."
Hypertension in children is frequently undiagnosed. Normal blood pressure is currently defined as a function of two continuous variables, age and height for each gender. Applying the current cutoff values to assess a child's blood pressure is time consuming. To separate the independent effect of age from that of height on blood pressure, we conducted a multiple group matched study to investigate if blood pressure levels in children with a given height distribution vary with age. An equal number of 2539 Chinese children from each of the four age groups (7, 8, 9 and 10 years) were individually matched by height, sex and geographic region. We used the matching technique to force the four age groups to have an identical height distribution. Systolic and diastolic blood pressures significantly increased with increasing age before matching. After matching, four groups had strikingly similar levels of blood pressures, and the differences among four groups were small and not statistically significant. Once height is taken into consideration, age has little impact on blood pressure. Our findings, if confirmed in children of other ages, suggest that blood pressure percentile charts can be considerably simplified by establishing normal percentiles according to height alone for each gender.Journal of Human Hypertension advance online publication, 12 May 2011; doi:10.1038/jhh.2011.45.

Medical and Biotech [MESH] Definitions
Comparison of the BLOOD PRESSURE between the BRACHIAL ARTERY and the POSTERIOR TIBIAL ARTERY. It is a predictor of PERIPHERAL ARTERIAL DISEASE.
Blood pressure levels that are between normotension and hypertension. Individuals with prehypertension are at a higher risk for developing cardiovascular diseases. Generally, prehypertension is defined as SYSTOLIC PRESSURE of 131-139 mm Hg and/or DIASTOLIC PRESSURE of 81-89 when the optimal is 120/80 mm Hg. For diabetics and other metabolism diseases the prehypertension is around 110-129/70-79 mm Hg.
Method in which repeated blood pressure readings are made while the patient undergoes normal daily activities. It allows quantitative analysis of the high blood pressure load over time, can help distinguish between types of HYPERTENSION, and can assess the effectiveness of antihypertensive therapy.
Persistently high systemic arterial BLOOD PRESSURE. Based on multiple readings (BLOOD PRESSURE DETERMINATION), hypertension is currently defined as when SYSTOLIC PRESSURE is consistently greater than 140 mm Hg or when DIASTOLIC PRESSURE is consistently 90 mm Hg or more.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
