本研究旨在界定臺灣男性白領上班族群的身體活動型態，並分析不同身體活動型態與肥胖指標間的關係。橫斷式研究中有350位（21-75歲）個案，以世界衛生組織的心血管疾病趨勢及決定因子研究的身體活動問卷測量每日身體活動量能量消耗。肥胖指標有體重、身體質量指數、腰臀圍比、身體脂肪百分比、總膽固醇、三酸甘油脂、高密度膽固醇、低密度膽固醇。經由集群分析找到三種身體活動型態：工作導向型、活躍生活型及靜態生活型。工作導向型平均的工作時數最多（10.5小時／天）；活躍生活型休閒活動最多（1小時／天）；靜態生活型則有最多的輕度活動（7小時／天）。用美國疾病管制局的有助健康之身體活動推薦量（中等費力身體活動達150分鐘／週）當切點時發現：沒有達到標準的活躍生活型、靜態生活型、工作導向型各佔1.1%，15.2%及29.1%。高工作負擔但活動不足的工作導向型男性，在調整過年齡後有最差的肥胖指標（體重、身體質量指數、腰臀圍比、脂肪百分比）。

The purposes of this study were to identify patterns of physical activity among white-collar men in Taiwan and to analyze the relationships between physical activity patterns and obesity indices. This cross-sectional survey included 350 subjects (between 21 and 75 years old). The Monitoring Trends and Determinants of Cardiovascular Disease Optional Study of Physical Activity Questionnaire (MOSPA-Q), developed and published by the World Health Organization (WHO) was used to measure subjects' daily energy expenditures attributed to physical activity. Obesity indices included body weight, body mass index (BMI), waist/hip ratio (WHR), body fat percentage, total cholesterol, triglycerides, high-density lipoprotein (HDL), and low-density lipoprotein (LDL). Three patterns of physical activity, namely work-oriented, active, and light-active lifestyles, were identified through cluster analysis. The work-oriented group reported spending the most amount of time on work-related activities (10.5 hours/week). The active group spent the most time (1 hour/day) of the three groups on leisure activities. The light-active group spent the most time (7 hours/day) of the three groups on light activities. Referencing the 150 minutes/week of moderate- intensity physical activity recommended by the US Centers for Disease Control and prevention (CDC) for health gain as a cut-off point, 1.1%, 15.2%, and 29.1% of subjects in the active, light-active and work-oriented groups, respectively, failed to achieve this minimal level. Those in the work-oriented group categorized in high work-overload and prevalent inactivity situations returned the worst obesity indices (Body weight, BMI, WHR, and body fat percentages) adjusted by age.
