The purpose of this study was to test the hypothesis that blue-collar workers have an increased risk of coronary heart disease. Subjects were 653 male (mean age, 32.6 years) and 492 female (mean age, 26.3 years) workers employed during 1993 at a computer manufacturing company. The measurements determined were body mass index (BMI), waist to hip ratio (WHR), skinfold thickness, blood pressure, grip strength, back strength, vertical jump and trunk flexion. Male blue-collar workers had significantly higher WHR (P < 0.001), systolic blood pressure (P = 0.031), grip strength (P = 0.030), and standing flexion (P = 0.038) than do white-collar workers. Female blue-collar workers had significantly higher BMI (P = 0.018), WHR (P < 0.001), and grip strength (P = 0.007). Blue-collar workers took significantly less exercise, and habitually snacked (females only), smoked and drank more alcohol (males only) than white-collar workers. In conclusion, blue-collar workers have more intra-abdominal fat than white-collar workers of either sex. The difference may be due to factors contributing to the less healthy lifestyles of blue-collar workers.
本研究的目的是检验蓝领工人患冠心病风险增加这一假设。研究对象为1993年受雇于一家计算机制造公司的653名男性（平均年龄32.6岁）和492名女性（平均年龄26.3岁）工人。所测定的指标有体重指数（BMI）、腰臀比（WHR）、皮褶厚度、血压、握力、背部力量、垂直跳跃和躯干前屈。男性蓝领工人的腰臀比（P < 0.001）、收缩压（P = 0.031）、握力（P = 0.030）和站立前屈（P = 0.038）显著高于白领工人。女性蓝领工人的体重指数（P = 0.018）、腰臀比（P < 0.001）和握力（P = 0.007）显著更高。与白领工人相比，蓝领工人锻炼明显较少，有习惯性吃零食（仅女性）、吸烟和饮酒（仅男性）的习惯。总之，蓝领工人比任何性别的白领工人都有更多的腹部内脂肪。这种差异可能是由于导致蓝领工人生活方式不太健康的因素所致。
