職場員工客觀測量身體活動、靜態行為與肥胖風險之研究

世界衛生組織指出肥胖與其相關疾病是21世紀最嚴重的全球公共衛生挑戰之一。肥胖已被證實與國人十大死因中的心血管疾病、糖尿病、高血壓、肺部疾病等有相關。近年來，由於科技日新月異，工作型態的改變(以坐在辦公室為主) 以及娛樂活動的改變 (如看電視、打電動)，職場員工的身體活動量減少及靜態行為增加，皆可能增加肥胖的風險。據此，本研究欲探討職場員工身體活動、靜態行為與肥胖之關聯性，以作為未來職場健康促進策略擬定之基石。本研究為橫斷性研究設計，於2020年8月至10月間以方便取樣方式進行取樣；本研究對象選取桃園市某生技公司員工為本研究調查之母群體，結合線上問卷及三軸加速規測量身體活動量與靜態行為，共有51筆有效樣本。資料分析利用SPSS 23.0進行平均數、標準差及邏輯斯迴歸分析。研究調查結果發現「連續30分鐘久坐時間3.5小時/天」與肥胖之關聯性達顯著正相關；「輕強度身體活動180分鐘/天」與肥胖之關聯性達顯著負相關；表示身體活動時間越多，靜態時間越少，肥胖風險越低，因此未來在職場健康促進策略，可著重於增加職場員工身體活動量，減少各項久坐時間及增加中斷久坐行為，以有效預防肥胖風險之發生。

The World Health Organization states that obesity and its related diseases are one of the most serious global public health challenges of the 21st century. Obesity is associated with higher risks of cardiovascular disease, diabetes, hypertension, and lung disease, which are the top ten causes of death in Taiwan. Recent years, due to the rapid development of technology, changes in work patterns (mainly sitting in the office) and changes in recreational activities (such as watching TV, playing video games), the decrease in physical activity and the increase in sedentary behaviors of workplace employees may increase obesity risks. Accordingly, this study intends to explore the relationship of workplace employees' physical activity and sedentary behavior with obesity risks, for designing future workplace health promotion strategies. This study was designed to be a cross-sectional study, and sampling was conducted by convenient sampling between August and October 2020. The subjects were recluded from a biotechnology company in Taoyuan City. Online demographic questionnaire were also employed and the three-axis accelerometer were used to measure physical activity and sedentary behavior. After data cleaning there were 51 valid samples in this study. Binary logistic regression was used for analysis. The findings of the study showed that "3.5 hours/day of sedentary time for 30 minutes" was significantly and positively correlated with obesity. "Light-intensity physical activity 180 minutes/day" are significantly negatively correlated with obesity, indicating that the more physical activity time, the less static time, and the lower the risk of obesity. Therefore, in the future, workplace health promotion strategies can focus on increasing the physical activity of workplace employees, reducing sedentary time and increasing interruption of sedentary behaviors, so as to effectively prevent the occurrence of obesity.
