背 景第II型糖尿病為國人常見慢性疾病，影響病人的生活品質，成為健康領域中重要議題。 目 的探討第II型糖尿病病人身體活動、生活品質之現況及生活品質之預測因子。 方 法本研究為橫斷式研究，於2014年1月至10月在台北市某區域教學醫院採方便取樣，共收案100位第 II型糖尿病病人。以七日身體活動回憶量表及SF-36生活品質量收集資料。 結 果(1)有42%的研究對象在過去7日沒有運動習慣，以輕度活動為主。(2)病人的生活品質屬中等程度， 病人年齡（r = -.231, p < .05）、教育程度（r = .279, p < .01）和生理面向生活品質有顯著相關。HbA1c 值高於6.5%的病人比低於6.5%者在生理面向（t = -2.595, p < .05）及心理面向（t = -2.522, p < .05）生 活品質顯著較差。(3)糖尿病住院次數（r = -.256, p < .05）、有無合併其他疾病（t = 3.29, p = .042）與生 理面向生活品質有顯著相關。(4)身體活動與心理健康呈顯著負相關（r = -.205, p < .05），身體活動與 生活品質其餘構面均沒有顯著相關性（p > .05）。(5)因糖尿病住院次數是生活品質之顯著預測因素， 可解釋14.5%的生理面向生活品質，可解釋5.5%心理面向生活品質。 結 論／ 實務應用 當病人血糖得到良好的控制可擁有較好的生活品質，本研究結果可提供臨床參考。

Background: Type II diabetes, a major healthcare issue, is a common chronic disease in Taiwan that affects the quality of life of sufferers. Purpose: To understand the physical activity status and the quality of life of patients with type II diabetes mellitus and to explore the related predictors of quality of life. Methods: This cross-sectional study used convenience sampling to collect relevant data between January to October 2014 from a regional teaching hospital in Taipei. One hundred patients with type II diabetes were included as participants. The seven-day physical activity recall scale and the SF-36 were used to collect data. Result: (1) Forty-two percent of the participants had engaged in no habitual exercise during the prior seven days and had engaged primarily in mildly strenuous activities. (2) The quality of life of the participants was moderate. Patient age (r = −.231, p < .05) and education level (r = .279, p < .01) were significantly correlated with the physical component of quality of life. A significant difference was found between levels of HbA1c and the physical (t = -2.595, p < .05) and mental (t = -2.522, p <.05) components of quality of life. (3) The number of hospitalizations attributable to diabetes (r = −.256, p < .05) and diabetes with a comorbidity (t = 3.29, p = .042) were significantly associated with the physical component of quality of life. (4) Physical activity was significantly and negatively correlated with the mental component of quality of life (r = -.205, p <.05), but physical activity was not significantly correlated with the other components of quality of life (p > .05). (5) The number of hospitalizations due to diabetes was a significant predictor of quality of life, explaining 14.5% and 5.5% of the physical and mental components of quality of life, respectively. Conclusion: Good control of blood glucose was shown to promote quality of life in the type II diabetes mellitus patients in this study. The findings may be referenced and applied in clinical practice.
