Our aim was to examine the contribution of past and current physical workload to occupational class differences in leisure-time physical inactivity.
Data were taken from the Finnish population-based Health 2000 Survey of employees aged >or=30 years (N=3355). We assessed physical activity during leisure time using a questionnaire and dichotomized responses to inactive versus active. Occupational class was classified into white- and blue-collar worker. Adjustments were made for current work-related factors, other measures of socioeconomic position, clinically diagnosed chronic diseases, other health behaviors, and history of physical workload. We applied sequential logistic regression to the analyses.
Inactivity during leisure time was more common in blue-collar employees than in their white-collar counterparts [women odds ratio (OR) 1.50, 95% confidence interval (95% CI) 1.12-2.00; men OR 1.66, 95% CI 1.30-2.12]. These occupational differences were not due to working hours, work schedule, or chronic diseases. Among women, current job strain decreased the occupational differences in leisure-time physical inactivity slightly (OR 1.37, 95% CI 0.99-1.04). Education and household income contributed to occupational differences for men (OR 1.45, 95% CI 1.02-2.07), but had no additional effect among women. The occupation differences in leisure-time physical inactivity disappeared after adjusting for smoking and body mass index in women (OR 1.33, 95% CI 0.97-1.83) and men (OR 1.27, 95% CI 0.88-1.82) and were further attenuated after adjusting for history of physical workload among men (OR 1.07, 95% CI 0.67-1.72).
Having a long history of exposure to physical work (among men) and a high current job strain (among women) contributed to occupational class differences in leisure-time physical inactivity.
本研究旨在探讨既往和当前体力工作负荷对职业阶层间休闲时间体力活动不足差异的贡献。
数据来自芬兰基于人群的健康 2000 年调查，调查对象为年龄≥30 岁的员工（N=3355）。我们使用问卷评估了休闲时间的体力活动情况，并将回答归类为不活跃和活跃。职业阶层分为蓝领和白领工人。调整了当前与工作相关的因素、其他社会经济地位指标、临床诊断的慢性病、其他健康行为以及体力工作负荷史。我们应用序贯逻辑回归进行分析。
与白领员工相比，蓝领员工在休闲时间不活动的比例更高[女性比值比（OR）1.50，95%置信区间（95%CI）1.12-2.00；男性 OR 1.66，95%CI 1.30-2.12]。这些职业差异并非由于工作时间、工作时间表或慢性病所致。对于女性，当前工作压力略微降低了休闲时间体力活动不足的职业差异（OR 1.37，95%CI 0.99-1.04）。教育和家庭收入对男性的职业差异有影响（OR 1.45，95%CI 1.02-2.07），但对女性没有额外影响。在女性（OR 1.33，95%CI 0.97-1.83）和男性（OR 1.27，95%CI 0.88-1.82）中调整吸烟和体重指数后，休闲时间体力活动不足的职业差异消失，在男性中进一步调整体力工作负荷史后（OR 1.07，95%CI 0.67-1.72），这种差异进一步减弱。
长期暴露于体力工作（男性）和当前高工作压力（女性）导致了休闲时间体力活动不足的职业阶层差异。
