调查新疆阿勒泰地区哈萨克族(哈族)老年农、牧民821人,高血压患病率31.43％,明显高于老年前期组(16.76％)。收缩压及舒张压值与年龄的相关系数(r)在农民分别为0.20(P<0.01)及0.13(P<0.01);在牧民分别为0.23(P<0.01)及0.15(P<0.05)。与一般报告不同之处是哈族老年人的舒张压也随增龄而增高。其原因可能与哈族老年人中自中年原发性高血压延续而来的高血压患者的比例随增龄而增加,哈族人群血压水平普遍偏高及其饮食摄钠高而钾及维生索C低等因素有关。 A total of 821 elderly peasants and herdsmen from Kazak (Ha ethnic) in Altay Prefecture of Xinjiang Autonomous Region were surveyed. The prevalence of hypertension was 31.43%, significantly higher than that of the pre-senile group (16.76%). The correlation coefficients of systolic and diastolic blood pressure values ​​with age were 0.20 (P <0.01) and 0.13 (P <0.01) for peasants, 0.23 (P <0.01) and 0.15 (P <0.05) for pastoralists respectively. The difference with the general report is that the diastolic blood pressure of Elderly people in Kazakhstan increases with age. The reason may be related to the increase of the proportion of hypertensive patients in middle-aged people with essential hypertension from the middle-aged in the Elderly. The prevalence of hypertension in the Ha ethnic population is generally high and the dietary intake of sodium is high. Health C cable low-level factors.
