Sleep disturbance in the older inpatients may have adverse effects, increasing chances of cardiovascular disease, risk of falls and length of hospital stay. Sleep disturbance may be related to the medical care environment of light at night. This was a cross-sectional study to investigate the relationship between light exposures at night and sleep in hospitalized older patients. The research instruments used in this study included the Pittsburgh Sleep Quality Index (PSQI), Sleep Dairy, and Actigraphy. A total of 55 older patients with a mean age of 71.5 ± 7.5 years were recruited from the rehabilitation wards of two medical centers in Taichung City. SPSS 20 statistical software was used for statistical analysis. Results show that the average light intensity during nighttime sleep was 9.9Lux (Median), whereas the duration of light <5Lux during sleep were 403 minutes, accounting for 86.4% of total sleep time (Median). The subjective sleep quality of hospitalized older patients was poor (PSQI score：6.2±3.7), with a subjective sleep latency (SL) of 39.4 minutes and subjective wake after sleep onset (WASO) of 40 minutes. For objective sleep indicators, their sleep efficiency (SE) was 69.1%, with a total sleep time (TST) of 366.1 minutes, and WASO of 153 minutes. Light intensity during nighttime sleep was found to have significant relationships with subjective WASO (p=0.037) and self-perceived interrupted sleep (p=0.037) in the sleep diary. Hospitalized older patients who experienced higher duration or percentage of nighttime light intensity ≥5Lux had frequent episodes of subjective WASO and self-perceived interrupted sleep. It is showing that increased illumination during nighttime sleep will affect the duration and number of sleep interruptions. Result of this study provides an understanding of the sleep quality and illumination distribution at night in hospitalized older patients in a medical environment and can be used as a reference for setting ward environment in medical institutions.睡眠品質老人夜晚光線睡眠活動記錄器sleep qualityelderlylight at nightActigraphythesis
