抑郁症状对老年人健康预期寿命的影响

目的探讨抑郁症状对北京市城乡老年人群预期寿命（life expectancy, LE）、健康预期寿命（active life expectancy, ALE）的影响。方法2009年采用老年抑郁量表对2038例60岁以上老年人行抑郁症状和体能评估。根据能否独立完成日常生活活动评定健康与否。2011年对该样本进行随访。应用多状态寿命表IMaCH软件计算各年龄段正常组与有抑郁症状组的LE、ALE和ALE的百分比值。结果本次调查的2038例中有抑郁症状者294例，检出率为14.4%。 LE、ALE和ALE的百分比值随着年龄的增加呈下降趋势。在城区正常的老年人群中，女性的LE高于男性，但是女性的ALE和ALE占LE的百分比均低于男性；而在城区有抑郁症状的老年人群中，女性的LE、ALE和ALE占LE的百分比均低于男性。农村女性的LE和ALE高于男性，但是ALE占LE的百分比均低于男性。在城市和农村，正常老年人的LE、ALE和ALE占LE的百分比均高于有抑郁症状的老年人；在正常和有抑郁症状的男性老年人群中，城区老年人的LE、ALE和ALE占LE的百分比均高于农村老年人。结论抑郁症状对北京市老年人的LE、ALE和ALE占LE的百分比均有显著影响，特别是对农村老年人和女性老年人影响更显著。

Impact of depressive symptoms on the active life expectancy in the elderly

Objective To study the impact of depressive symptoms on the life expectancy （LE）, active life ex-pectancy （ALE） in Beijing urban and rural elderly population. Methods The assessment of depressive symptoms was con-ducted in 2038 subjects in 2009 by using the geriatric depression scale （GDS）. Healthy or not was assessed according to whether th0000000e subjects could independently completed the activities of daily living （ADL）. The samples were followed up in 2011. The LE, ALE and percentage of ALE in each age stage in elderly with or without depressive symptoms were cal-culated by using the multi-state life table （IMaCH software）. Results There were 294 old people with depressive symp-toms among the 2 038 elderly, the prevalence of depressive symptoms was 14.4%. The LE, ALE and percentage of ALE were decline with aging. Among community dwelling urban elderly without depressive symptoms, the LE of female was higher than that of male, the ALE and percentage of ALE were lower than the latter. However, among community dwelling urban elderly with depressive symptoms, the LE, ALE and percentage of ALE of female were lower than that of male. How-ever, among community dwelling rural elderly with or without depressive symptoms, the LE and ALE of female were higher than those of male, the percentage of ALE was lower than the latter. Regardless of in urban or rural, the LE, ALE and per-centage of ALE of normal elderly were higher than those of the elderly with depressive symptoms. And regardless of de-pressive symptoms, the LE, ALE and percentage of ALE of urban population were higher than those of the rural population. Conclusion Depressive symptoms remarkably impact the LE, ALE and percentage of ALE on the elderly in Beijing, es-pecially for rural-dwelling elderly and female elderly.
