我们在舟山地区选择了65名高血压患者和65名正常血压者进行高血压病的遗传度调查,测量了他们的一级亲属(父母、同胞、子女)共1006人血压。结果表明(?)山地区高血压病有明显的家族聚集现象,依照Falconer公式,计算得遗传度为60％。此外,遗传度是一个用来衡量遗传因素对人群的血压变异的影响与环境因素相比较所占的比例的概念。数据提示遗传因素对舟山地区高血压病的发生较环境因素更显重要。
We selected 65 hypertensive patients and 65 normotensive subjects in Zhoushan to carry out a genetic survey of hypertension and measured a total of 1006 blood pressure in their first-degree relatives (parents, siblings and children). The results showed that there was a significant familial aggregation of hypertensive disease in mountainous areas, and the heritability was calculated to be 60% according to the Falconer formula. In addition, heredity is a concept used to measure the effect of genetic factors on blood pressure variability in the population compared with environmental factors. Data suggest that genetic factors in Zhoushan Hypertension is more important than the environmental factors.
