摘　　要：目的 分析中老年高血压患者动态血压的昼夜节律性.方法 选取40~91岁的原发性高血压病人118 例进行24 h态血压监测,其中男性68 例,占57.6%;女性50 例,占42.4%.并将年龄分为中年（40~64岁）、老年（65~79岁）和高龄（80~91岁）三组.结果 男性24 h、白昼和夜间平均舒张压都高于女性,组间差异均有统计学意义,而收缩压组间比较,差异均无统计学意义.中年组、老年组和高龄组高血压病人收缩压随年龄组增高而上升,舒张压则表现为下降趋势.中年组、老年组和高龄组非杓型高血压检出率分别为65.1%、75.0%和93.5%,随着年龄组增高非杓型高血压检出率呈增高趋势（趋势χ2 =7.759,P〈0.01）.结论 高血压病人昼夜节律异常率随着年龄增加而增高,临床上应根据病人的昼夜节律特点制定个体化的治疗方案.Objective To explore the circadian rhythm in elderly patients with Ambulatory blood pressure （ABPM）. Method 24 h AB- PM was measured 118 patients with essential hypertension, the male 68 cases, accounting for 57.6% ; Women in 50 cases, accounting for 42.4%. The patients were divided into middle-aged （40 - 64 years old）, old （65 - 79 years old） and aged （80 - 91 years） three Middle aged group. Results The male of 24hDBP, dDBP, nDBP, NMBP were significantly high than the female, there have been statistical difference, the systolic blood pressure groups have no statistical significance. Middle aged group, old group and elder group patients with hypertension elevated systolic blood pressure increased with age group, diastolic blood pressure showed a downward trend. Middle aged group, old aged group and elder group of non dipper type hypertension detection rates were 65.1%, 75% and 93.5%, With the in- crease of age group and non dipper type hypertension prevalence rate increased （Trend of x^ 2 = 7. 759, P 〈 0.01 ）. Conclusion Hyper- tension circadian rhythm of abnormal rate increased with the increase of age, Clinical treatment should be individualized according to the characteristics of the circadian rhythm of patients.
