Abstract:
Objective The aim of this 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 Beijing. Methods 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.Results 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 ALE/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.Conclusion 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.
