The aim of the study is to explore the influence of hypertension on life expectancy (LE), active life expectancy (ALE) and active life expectancy/life expectancy (ALE/LE) among senior citizens in Beijin.
The sample derived from Beijing multidimensional longitudinal study on aging, baseline survey consisted of 1847 elderly people aged 60 years and over dwelling in the communities from one urban district (Xuanwu), one suburban country (Daxing) and one mountainous country (Huairou) in Beijing, 2004. Cluster, stratified and randomly selected sampling technique was used and a follow-up program was carried out in 2007. The subjects were invited to fill in questionnaires at home through well-trained interviewers, together with medical history of hypertension and repeated blood pressure measurements adopted. The state of activity was defined according to whether they could perform activities of daily life (ADL). IMaCH software for multi-state life table method was used to calculate the life expectancy (LE), active life expectancy (ALE) and active life expectancy/life expectancy (ALE/LE) in people with hypertension and normal blood tension, as well as on those people with hypertension with or without cardio-cerebral disease.
The study manifested that hypertensives were associated with the reduction of LE, ALE and ALE/LE compared to the normotensives. The ALE/LE was descending along with ageing, and the speed of reduction was much faster in the hypertensive group, especially within senile population. LE, ALE and LE/LE among the hypertensives with cardio-cerebral vascular diseases were shorter than the hypertensives without the disease. Difference in ALE/LE was striking in people with virile senility.
Hypertension remarkably impacted the active life expectancy on senior citizens living in Beijing, especially for elderly. Hypertensives with cardio-cerebral vascular diseases exerted further influence on active life expectancy, particularly among population of virile senility. The finding underlined the tremendous importance of preventing high blood pressure and its complication.
本研究旨在探讨高血压对北京老年人预期寿命（LE）、健康预期寿命（ALE）以及健康预期寿命/预期寿命（ALE/LE）的影响。
样本来自北京多维老龄化纵向研究，2004年基线调查包括北京市一个城区（宣武）、一个郊区县（大兴）和一个山区县（怀柔）社区中1847名60岁及以上的老年人。采用整群、分层和随机抽样技术，并于2007年开展随访项目。通过训练有素的访员邀请受试者在家中填写问卷，同时采用高血压病史及重复血压测量。根据其是否能够进行日常生活活动（ADL）来定义活动状态。使用IMaCH软件的多状态生命表法计算高血压患者和血压正常者的预期寿命（LE）、健康预期寿命（ALE）以及健康预期寿命/预期寿命（ALE/LE），以及患有或未患有心脑血管疾病的高血压患者的上述指标。
研究表明，与血压正常者相比，高血压患者的LE、ALE和ALE/LE降低。ALE/LE随年龄增长而下降，且在高血压组中下降速度更快，尤其是在老年人群中。患有心脑血管疾病的高血压患者的LE、ALE和ALE/LE低于无该疾病的高血压患者。在老年男性中，ALE/LE的差异显著。
高血压对北京老年人的健康预期寿命有显著影响，尤其是对老年人。患有心脑血管疾病的高血压患者对健康预期寿命有进一步影响，特别是在老年男性人群中。这一发现凸显了预防高血压及其并发症的极其重要性。
