儿童血压的追踪研究

A FOLLOW UP STUDY OF BLOOD PRESSURE IN CHILDREN IN FANGSHAN COUNTY, BEIJING

为了解儿童血压随年龄而变化的规律,进而探讨用儿童血压水平预示未来成人血压水平的可能性,我们对1981年初查的2946名4～14岁农村儿问题时进行了4年和6年的追踪观察。结果表明:在校正年龄和体重的混杂作用后,仍显示儿童血压均值随年龄而上升。同时,儿童血压存在着轨迹现象,说明儿童血压水平对成人血压有一定的预示价值。

Epidemiological studies of blood pressure in children may provide insight into aetiology as well as possibility of preventing essential hypertention, In order to find out the natural history of essential hypertension and possible tracking phenomenon of blood pressure in children, in 1981, we examined a group of 2916 children in Fangshan county, Beijing, and reexamined them in 1985 and 1987.The results indicate: This study has shown an increase in average level of blood pressure with age during childhood. The same results have been found after adjusting age and body weight. However, the increase of diastolic pressure is less marked than that of systolic pressure. There exists a certain degree of blood pressure 'tracking phenomenon'' in children. Althrough the value of tracking coefficients is low, there is a statistically significant positive correlation. Although the actual blood pressure level is the best predictor of the future blood pressure level, yet by now, the predictive value of blood pressure in childhood is rather too low for us to determine the law of variability.
