Background

Low back pain is a highly prevalent and disabling musculoskeletal disorder. Physical activity is widely used as a prevention strategy for numerous musculoskeletal disorders; however, there is still conflicting evidence as to whether physical activity is a protective or risk factor for low back pain or whether activity levels differ between people with and without low back pain.

Objective

To investigate the association between low back pain and different types (occupational and leisure) and intensities (moderate and vigorous) of physical activity.

Methods

This is cross-sectional observational study. We included in this study a total of 1059 individuals recruited from a Spanish twin registry with data available on low back pain. Outcome: Self-reported leisure and occupational physical activity were the explanatory variables. The low back pain outcome used in this study was recurrent low back pain.

Results

Our results indicate that leisure physical activity is associated with a lower prevalence of recurrent low back pain. In contrast, occupational physical activity, such as carrying, lifting heavy weight while inclined, awkward postures (e.g. bending, twisting, squatting, and kneeling) are associated with a higher prevalence of recurrent low back pain. There was no statistically significant association between other occupational physical activities, such as sitting or standing, and low back pain.

Conclusion

Leisure and occupational physical activity are likely to have an opposed impact on low back pain. While leisure physical activity appears to be protective, occupational physical activity appears to be harmful to low back pain. Future longitudinal studies should assist in formulating guidelines addressing specific types and intensity of physical activity aimed at effectively preventing low back pain.

职业或休闲运动与下背痛相关吗？来自1059名参与者的横断面研究的见解。

背景

腰背痛是一种高度流行的致残性肌肉骨骼疾病。体育锻炼被广泛用作许多肌肉骨骼疾病的预防策略；但是，关于体育锻炼是否是下腰痛的保护性因素或危险因素，或者有无腰背痛的人之间的活动水平是否存在差异，仍有争议的证据。

目的

研究腰背痛与不同类型（职业和休闲）和强度（中度和剧烈）的体育活动之间的关联。

方法

这是横断面观察研究。我们在这项研究中纳入了从西班牙双生子登记处招募的1059名个体，并提供了有关腰痛的数据。结果：自我报告的休闲和职业体育活动是解释性变量。本研究中使用的下腰痛结局是复发性下腰痛。

结果

我们的结果表明，休闲运动与复发性下腰痛的患病率较低相关。相反，职业体育活动，例如背负，举重，倾斜，笨拙的姿势（例如，弯曲，扭曲，下蹲和跪下）与复发性下腰痛的患病率较高相关。在其他职业体育活动（例如坐着或站着）和下背部疼痛之间没有统计学上的显着关联。

结论

休闲和职业体育锻炼可能会对腰痛产生相反的影响。休闲体育锻炼似乎具有保护作用，而职业体育锻炼似乎对下腰痛有害。未来的纵向研究应有助于制定针对特定类型和强度的体育活动的指南，以有效预防腰痛。
