In the majority of countries around the world, a decrease in the leisure-time physical activity is observed. The aim of the study was to evaluate the correlation between occupational energy expenditure and leisure-time physical activity. Moreover, the correlation between other factors and leisure-time physical activity was assessed.
The study was performed in a randomly selected group of full-time employees (272 men and 236 women) living in the city of Lódź. Logistic regression was used to estimate odds ratios and 95% confidence intervals as well as to control the effects of occupational workload and leisure-time physical activity limitations. Physical activity was determined by the Seven Day Physical Activity Recall (SDPAR).
Leisure-time physical activity was strongly associated with energy expenditure on occupational physical activity in men and women. Among men who expended 4000 kcal/week or more on occupational physical activity, the risk of inactivity at leisure was 1.5 times higher than in men whose weekly energy expenditure on occupational activity did not exceed 4000 kcal (adjusted OR = 1.33, 95% CI: 1.06-2.34). Among women who expended 3500 kcal/week or more on occupational physical activity, the risk of not taking up leisure-time physical activity was also higher as compared to those whose weekly energy expenditure on occupational activity was lower than 3500 kcal (adjusted OR = 1.41, 95% CI: 1.09-3.40).
Prophylactic schedules associated with the improvement of leisure-time physical activity should be addressed to all adults, particularly to blue-collar workers. Future programs aimed at increasing physical activity in adults should consider work-related factors.
在世界上大多数国家，人们休闲时间的体力活动都在减少。本研究旨在评估职业能量消耗与休闲时间体力活动之间的相关性。此外，还评估了其他因素与休闲时间体力活动之间的相关性。
本研究在罗兹市随机抽取的一组全职员工（272名男性和236名女性）中进行。采用逻辑回归来估计优势比和95%置信区间，并控制职业工作量和休闲时间体力活动限制的影响。通过七日体力活动回忆法（SDPAR）来确定体力活动情况。
休闲时间体力活动与男性和女性职业体力活动中的能量消耗密切相关。在职业体力活动中每周消耗4000千卡或更多能量的男性中，休闲时不活动的风险比职业活动每周能量消耗不超过4000千卡的男性高1.5倍（调整后的优势比=1.33，95%置信区间：1.06-2.34）。在职业体力活动中每周消耗3500千卡或更多能量的女性中，与职业活动每周能量消耗低于3500千卡的女性相比，不进行休闲时间体力活动的风险也更高（调整后的优势比=1.41，95%置信区间：1.09-3.40）。
与改善休闲时间体力活动相关的预防计划应面向所有成年人，尤其是蓝领工人。未来旨在增加成年人身体活动的项目应考虑与工作相关的因素。
