The purpose of this study was to investigate the relationships of lifestyle factors, including energy intake and expenditure, to body mass index in male office workers. A total of 84 male office workers voluntarily participated in the study, and the participants’ lifestyle factors, which included body fat indicators such as body mass index, percent body fat, waist circumference, and waist-to-hip ratio, were measured. They also answered questionnaires recording their daily dietary intakes and average daily walking and sedentary time. For group analysis, the subjects were classified into normal weight (n=30) or overweight (n=54) groups based on a BMI cut-off point of 23.0kg/m2. Energy intake results showed that the overweight groups had significantly higher values for volume of dinner (p=.001), fat intake (p<.001), and frequency of skipping breakfast (p=.020) than the normal weight group. In terms of energy consumption, the overweight group had significantly lower values for commute time (p<.001) and significantly higher values for working hours (p=.017) and sedentary work time (p<.001) than the normal weight group. Pearson correlation analysis showed that dinner intake (p=.007) and sedentary work time (p<.041) were significantly related to BMI in both groups. Multiple linear regression analysis showed that dinner intake and sedentary work time were two independent predictors of BMI in office workers who participated in this study. In conclusion, the current findings of the study suggest that adopting healthy dietary habits, including dieting and regular meal times, as well as increased physical activity and reduced sitting time should be promoted as key components of lifestyle intervention for the prevention of body fatness in office workers.
