结论：社区老年人抑郁症的危险因素主要为智力活动能力低下、人际交往能力差、跌倒史、运动习惯差、独食等。此外，15项老年抑郁量表可预测日本老年人的8年死亡率。对抑郁症的干预方案如回忆、运动等虽未显示出统计学上的显著效果，但老年抑郁症的比例略有下降。

We clarified that lower intellectual activity, poor ability of communication, historyof fall, poor exercise habits and eating alone are the risk factors of depression amongthe community-dwelling elderly. Further, 15-item geriatric depression scale predicts8-year mortality in older Japanese. Although intervention program for depression suchas reminiscence and exercise did not show statistically significant effect, theproportion of depressive elderly was slightly declined.
