We measured the illuminance exposure for 3 days in winter of a convenience sample of 44 elderly people certified as requiring support in Japan's Hokuriku region. We calculated the illuminance ratio per minute during activity and while in bed and analyzed the relationship between illuminance, subjective sleep quality, and psychosomatic health. There was a significant negative correlation between illuminance and 15-item Geriatric Depression Scale scores. Multiple regression analysis indicated that depression scores were significantly related to age, level of required support, and illuminance. The findings suggest that environments without light and dark cycles increase depression scores in frail elderly people.
我们对日本北陆地区44名被认证为需要照料的老年人进行了便利抽样，测量了他们冬季3天的光照暴露情况。我们计算了活动期间和卧床期间每分钟的光照比率，并分析了光照、主观睡眠质量和身心健康之间的关系。光照与15项老年抑郁量表得分之间存在显著负相关。多元回归分析表明，抑郁得分与年龄、所需照料水平和光照显著相关。研究结果表明，没有明暗循环的环境会增加体弱老年人的抑郁得分。
