目標：瞭解臺灣地區成年人的休閒運動狀況，探討運動行為與健康行為、健康狀況、以及與健康有關的生活品質的關係。方法：分析2001年「國民健康訪問調查」資料，有效樣本為十八歲以上且完成調查中有關運動狀況之問題的7978位男性以及8154位女性。「規律運動者」為每週從事至少5次的中強度運動且總運動時間至少150分鐘者；或從事每次至少20分鐘且每週至少3次的高強度運動者。結果：約有21.0%的成年人為規律運動者，其中以走路為最常從事的運動；而有50.3%未從事任何運動。年齡、教育程度、蔬果攝取行為、日常生活行動困難程度與慢性疾病項數均為預測男女性運動行為的有效因素。而有規律運動習慣者在「身體生理功能」、「因身體生理問題角色受限」、「身體疼痛」、「一般健康狀況」、「活力狀況」與「心理健康」等SF-36量表的分數都顯著高於不運動者 (p＜0.001)。結論：臺灣地區近八成的成年人未達到規律運動的建議量，其中以25-44歲的青壯年、教育程度為國中以下、有日常活動功能障礙者、吸菸或肥胖的男性，以及體重過輕的女性為運動行為最不理想之族群。

Objectives: This study describes the patterns of leisure-time physical activity (LTPA) and assesses its association with health behaviors, health status and health-related quality of life.Methods: Data came from the 2001 National Health Interview Survey of Taiwan. A total of 7978 males and 8154 females completed the exercise questionnaire. “Regularly exerciser” was defined as one who exercised ＞=5 times a week and accumulating ＞= 150 minutes in moderate intensity or ＞=3 times a week for ＞=20 minutes per time in vigorous intensity.Results: About 21% of respondents reported as regular exercisers, while 50% reported no exercise during their leisure time. Walking was the most popular activity reported. In a multivariate logistic model, age, education status, fruit and vegetable consumption, chronic disease status, and difficulty in activities of daily living (ADL) were statistically significant correlates of exercise behavior. Analyses of the SF-36 dimensions showed that adults who exercised regularly also had significantly better scores than those who did not exercise (p＜0.001) in self-perceived physical function, role limitations due to physical problems, pain, general health, vitality, and mental health.Conclusions: Eight out of ten adults in Taiwan do not meet the CDC/ACSM recommendation for LTPA. Prevalence in LTPA was lowest among those 25-44 years of age, with less than middle school education, with restricted ADL, smoking or obese males, and underweight females.
