To investigate the relationship between leisure-time physical activity and work-related repetitive strain injury (RSI), adjusted for sociodemographic characteristics and work-related physical and stress factors.
The data source was the 2003 Canadian Community Health Survey, a national cross-sectional survey of 134,072 respondents. The analysis was limited to a sample of the survey population reporting full-time work during the past 12 months (n = 58,622). The outcome of interest was work-related RSI of the upper body. Multiple logistic regression was used to examine the relationship between the outcome and leisure-time physical activity level, adjusted for sociodemographic, health, and occupational characteristics. The potential effect of leisure-time physical activity with a high upper-body load was investigated in a secondary analysis.
The prevalence of upper-body work-related RSI was 5.9% in the Canadian population in 2003. An active lifestyle during leisure time was associated with a lower prevalence of work-related upper-body RSI (odds ratio 0.84, 99% confidence interval 0.75-0.95), after adjustment for work physical demands and other covariates. Female sex, obesity, smoking, age, work-related stress, and work physical demands were associated with RSI. In the secondary analysis, we did not find that participating in leisure-time activities with a high upper-body load was a risk factor for RSI.
Our study results indicate that being physically active during leisure time is associated with a decreased risk of upper-body occupational RSI, adding another potential health benefit to participation in leisure-time physical activity.
探讨休闲时间身体活动与工作相关的重复性劳损（RSI）之间的关系，并对社会人口学特征以及工作相关的身体和压力因素进行校正。
数据来源为2003年加拿大社区健康调查，这是一项对134,072名受访者进行的全国性横断面调查。分析仅限于在过去12个月内报告全职工作的调查人群样本（n = 58,622）。感兴趣的结果是与工作相关的上身RSI。采用多元逻辑回归分析来检验结果与休闲时间身体活动水平之间的关系，并对社会人口学、健康和职业特征进行校正。在二次分析中研究了具有高上身负荷的休闲时间身体活动的潜在影响。
2003年加拿大人群中与工作相关的上身RSI患病率为5.9%。在对工作身体需求和其他协变量进行校正后，休闲时间积极的生活方式与工作相关的上身RSI患病率较低相关（优势比0.84，99%置信区间0.75 - 0.95）。女性、肥胖、吸烟、年龄、工作相关压力和工作身体需求与RSI相关。在二次分析中，我们未发现参与具有高上身负荷的休闲活动是RSI的危险因素。
我们的研究结果表明，休闲时间进行身体活动与上身职业性RSI风险降低相关，这为参与休闲时间身体活动增加了另一项潜在的健康益处。
