睡眠對於身體健康與心理幸福感是很重要的，持續的睡眠困擾對心理健康有負面的影響，而且可能增加跌倒或憂鬱的危險。然而，睡眠困擾在老年族群是相當常見的。 運動與睡眠的相關研究已顯示運動習慣與自陳式睡眠品質有顯著相關；然而，過去文獻多使用主觀式測量工具，無法提供有關身體活動與睡眠品質研究足夠的證據；因此本研究擬採用主觀及客觀方式測量身體活動與睡眠，以補目前文獻不足之處。 本研究透過面訪方式於高雄市湖內社區65歲及以上的老年人完成調查研究，問卷內容包含社會人口統計變項、老年人身體活動量表以及匹茲堡睡眠量表；另外並透過客觀方式以三軸加速規ActiGraph-GT3X測量身體活動量。
Sleep is important for physical health and mental wellbeing. Persistence of sleep problem has negative effects for mental wellbeing and increases risks of fall or depression. However, sleep problem is common among older adults. Several studies have shown that exercise is associated with significant improvements in self-reported sleep quality. Nevertheless, most studies use subjective measurements, which are not able to not provide enough evidence for the relationships between physical activity and sleep quality. Therefore, this research examined the association between physical activity and sleep quality adopt subjective and objective measure of physical activity and sleep to fill the gap in the literature. Participants, aged 65 and older, were from the community of Hunei, Kaohsiung through face to face interview. The questionnaire included social demographic variables, Physical Activity Scale for the Elderly (PASE) and Pittsburgh Sleep Quality Index (PSQI). Objective physical activity was measured for one week with ActiGraph-GT3X accelerometer.
