In order to elucidate the association between care conditions and mortality rate, a two year longitudinal study was performed on 115 frail elderly living at home. The main results were as follows; 1. Of the 115 frail elderly, 45 persons (39.1%) died during the two years. 2. A multiple logistic regression analysis revealed that the following factors were correlated to their death: age, activities of daily living (ADL), type of bedding. 3. Although ADL level was lower in the bed group than the Japanese style bed (futon) group at the first survey, survival rate was 69.8% in bed group and 47.5% in futon group. The relative risk of death with beds was 0.61 (95% confidence intervals 0.38-0.96) and was statistically significant.
为了阐明护理条件与死亡率之间的关联，对115名居家体弱老年人进行了一项为期两年的纵向研究。主要结果如下：1. 在这115名体弱老年人中，有45人（39.1%）在两年内死亡。2. 多元逻辑回归分析显示，以下因素与他们的死亡相关：年龄、日常生活活动能力（ADL）、被褥类型。3. 尽管在首次调查时，卧床组的ADL水平低于日式床铺（蒲团）组，但卧床组的生存率为69.8%，蒲团组为47.5%。使用床铺的死亡相对风险为0.61（95%置信区间0.38 - 0.96），具有统计学意义。
