背　景：根據世界衛生組織的估計到了2020年，憂鬱疾病會變成全球疾病負擔的第二位。由於 台灣老人人口愈來愈多，導致台灣高齡化社會的來臨，所以台灣老人的心理健康更值 得關注。
目　的：本研究主要的目的，在於探討北台灣不同性別的社區老人，規律運動與憂鬱症狀之關聯。
方　法：本研究利用以抽取率與單位大小成比例方式（Probability Proportional to Size, PPS），抽 取北台灣65歲以上的老人。利用橫斷性研究及面訪收集老人運動行為、憂鬱症狀及憂 鬱相關因素。使用百分比、卡方、t檢定及邏輯斯迴歸等方式進行統計分析。
結　果：共1,020位老人完成問卷調查。研究對象平均為73.5歲，男性占44.5%、女性占55.5%； 有憂鬱症狀之個案共217 位（21.3%）、有規律運動之個案共585 位（57.4%）。邏輯斯迴 歸結果顯示：規律運動是老人憂鬱症狀的重要預測因子（勝算比3.54，95%信賴區間為 1.76-7.12），其餘如性別、慢性疾病、健康狀態等均與憂鬱症狀無顯著關聯。此外，不 論男性或女性老人，規律運動是憂鬱症狀的重要預測因子（男性勝算比4.76，95%信賴 區間為1.65-13.72；女性勝算比3.03，95%信賴區間為1.18-7.69），其餘因素與憂鬱症狀 皆無顯著關聯。
結 論／ 實務應用：由上述研究結果顯示，不論男女老人，規律運動都是憂鬱症狀的重要預測因子。應多鼓勵老人持續性地運動，以促進心理健康。

Background: According to World Health Organization, depressive disorder will be a Top 2 disease in the world by 2020. In light of Taiwan’s rapidly increasing elderly population, elderly psychological health is expected to become an increasingly important issue in healthcare.
Purpose: This study examines the association between regular exercise and depressive symptoms in community-dwelling older adults by gender in northern Taiwan.
Methods: The participants were selected using a probabilityproportional- to-size procedure from community-dwelling adults who were aged 65 years or older and living in northern Taiwan. A cross-sectional study and interviews were used to collect information about their exercise behaviors, depressive symptoms, and the factors influencing the depressive symptoms. Percentage, chisquare, t test, and logistic regression were used to analyze the data.
Result: One thousand twenty elderly individuals completed the questionnaires. Among the participants with the average age of 73.5 years, 44.5% were men, and 55.5% were women. Two hundred seventeen of the participants (21.3%) had depressive symptoms. Five hundred eighty-five of the participants (57.4%) exercised regularly. The result of logistic regression showed that regular exercisewas a significant predictor of depressive symptoms in elderly individuals (odds ratio = 3.54, 95%confidence interval [1.76, 7.12]). Other factors such as gender, chronicle diseases, and health status were not related to depressive symptoms. Moreover, both for male and female individuals, regular exercise was a significant predictor of depressive symptoms (odds ratio = 4.76, 95% confidence interval [1.65, 13.72] and odds ratio = 3.03, 95% confidence interval [1.18, 7.69], respectively). Other factors were not related to depressive symptoms.
Conclusions/Implications for Practice: This study shows regular exercise to be a significant predictor of depressive symptoms in both men and women. Therefore, senior citizens should be encouraged to exercise regularly as away to promote goodmental health.
