As a marker of body fat distribution and therefore level of obesity, the waist-to-hip ratio (W:H) is a good indicator of coronary heart disease risk status. The present study investigated the association between occupational status and life-style factors, and W:H of middle-aged Japanese male (n = 2,550) and female (n = 1,283) workers in a metal-products factory. A higher W:H was observed in the management level males as compared with the other male workers and we suggest this was promoted by the sedentary aspect of their work, as well as their higher levels of alcohol consumption and lower levels of leisure-time physical activity. In contrast, a higher W:H was recorded in female labourers, whose work was typically less sedentary as compared with female managers. Life-style factors included in the study were not related to this observation. We conclude that other unmeasured psychosocial factors may be important in promoting higher W:H in female labourers.
作为身体脂肪分布以及肥胖程度的一个指标，腰臀比（W:H）是冠心病风险状况的良好指示物。本研究调查了金属制品厂中年日本男性（n = 2550）和女性（n = 1283）工人的职业状况、生活方式因素与腰臀比之间的关联。与其他男性工人相比，管理层男性的腰臀比更高，我们认为这是由他们工作中久坐的性质、较高的酒精摄入量以及较低的休闲时间身体活动水平所导致的。相比之下，女性劳动者的腰臀比更高，她们的工作通常不像女性管理人员那样久坐。该研究中纳入的生活方式因素与这一观察结果无关。我们得出结论，其他未测量的社会心理因素可能在促使女性劳动者腰臀比升高方面很重要。
