[[alternative]]The relationship between physical activity and sleep quality of middle-aged women

[[abstract]]本研究主要目的在於分析中年婦女身體活動、睡眠品質在人口特徵及健康背景上的差異性，探討上述相關因素與中年婦女睡眠品質的關係及預測情形。採便利取樣，以某區域教學醫院參加健康檢查或子宮頸抹片篩檢門診階段性服務、年齡在40~65歲之間的婦女為研究對象。研究結果顯示： 一、中年婦女睡眠品質不佳者（PSQI>5分）佔87.5%，整體睡眠品質平 均得分為9.68分。 二、不同「年齡」、「身體質量指數（BMI）」、「婚姻狀況」、「日常 生活或上班主要的身體活動方式」以及「工作、生活等各方面綜合 壓力」的中年婦女，在睡眠品質上無顯著差異。 三、中年婦女若「生活習慣愈差」、「自覺整體健康狀況愈差」、「沒 有職業」、「子女數愈多」、「罹患慢性疾病總數愈多」及「教育 程度愈低」，其睡眠品質愈差。 四、中重度身體活動量之中年婦女，與其睡眠品質得分（PSQI）呈顯著 負相關。而有規律運動習慣者，其睡眠品質較佳。 五、「罹患慢性疾病總數」及「自覺整體健康狀況總分」兩個自變項對 中年婦女的睡眠品質最具影響力，可預測睡眠品質的變異量48.1%。[[abstract]]The purposes of this study were to compare the differences on sleep quality among the middle-aged women with different demographic characteristics, healthy variables and varied physical activities, to explore the relationship between sleep quality and varied physical activities, and to predict in the high risk group with poor sleep quality. The purposive sampling was conducted at a regional hospital in Taipei County and 208 of valid samples were collected with self-administered questionnaires. The results revealed that: 1.The average PSQI global score of total subjects was 9.68, and 87.5% of the subjects whose scores were greater than 5. 2.The subjects in the different age, body mass index (BMI), marital status, amount of physical activity and stress condition were not significantly correlated to their sleep quality. 3.The worse self-perceived health status, the poorer life style, without occupation, the more number of children, the more number of chronic diseases and the lower educational background the subjects were, the worse sleep quality they showed. 4.Relative amount of moderate to vigorous physical activity of the middle-aged women indicates negative correlation with the PSQI global score. 5.The number of chronic diseases and the self-perceived health status could explain 48.1% variance of sleep quality
