背景：超重和肥胖问题是现代社会当前和长期的主要健康问题之一。本文以澳大利亚全职成年人为样本，研究了职业性久坐时间与超重和肥胖(BMI=25)之间的关系，探讨了工作场所在这一问题中的作用。方法：2003年9月，从1579名全职成年男女中收集了年龄、性别、职业、体力活动、职业性久坐时间和BMI的数据。结果：职业性坐着时间平均为3小时/天，男性(209min)显著高于女性(189min，p=0.026)。单变量分析显示，在男性中，职业久坐时间与体重指数=25之间存在显著的相关性，而在女性中则没有。在调整了年龄、职业和体力活动后，报告每天坐着6小时的男性与每天坐着45分钟的男性相比，BMI>；=25的优势比为1.92(可信区间：1.17-3.17)。结论：在全职带薪工作的男性中，职业坐着时间与超重和肥胖独立相关。这些结果表明，工作场所可能在日益严重的超重和肥胖问题中扮演着重要角色。需要进一步的研究才能清楚地了解工作中坐着的时间与女性超重和肥胖之间的联系。
Background: One of the major immediate and long-term health issues in modern society is the problem of overweight and obesity. This paper examines the role of the workplace in the problem by studying the association between occupational sitting time and overweight and obesity (body mass index [BMI] >= 25) in a sample of adult Australians in full-time employment.Methods: Data on age, gender, occupation, physical activity, occupational sitting time, and BMI were collected in September 2003 from a sample of 1579 adult men and women in full-time employment at the time of the survey. Logistic regression was used to examine the association between occupational sitting time and overweight and obesity.Results: Mean occupational sitting time was > 3 hours/day, and significantly higher in men (209 minutes) than in women (189 minutes, p =0.026). Univariate analyses showed significant associations between occupational sitting time and BMI of >= 25 in men but not in women. After adjusting for age, occupation, and physical activity, the odds ratio for BMI >= 25 was 1.92 (confidence interval: 1.17-3.17) in men who reported sitting for > 6 hours/day, compared with those who sat for < 45 minutes/day.Conclusions: Occupational sitting time was independently associated with overweight and obesity in men who were in full-time paid work. These results suggest that the workplace may play an important role in the growing problem of overweight and obesity. Further research is needed to clearly understand the association between sitting time at work and over-weight and obesity in women.
