The association between leisure time physical activity and low back pain in young adults is unclear and is in the need of prospectively obtained evidence. This study examined the course of low back pain and the association between low back pain and leisure time physical activity in a cohort of young adults in their transition from school to working life.
Both low back pain and leisure time physical activity was monitored over a 6.5 year period in 420 subjects starting out as students within hairdressing, electrical installation and media/design. The association between physical activity and low back pain was investigated through the follow-up period by using linear mixed models analysis.
Low back pain was significantly influenced by time and overall there was a decreasing trend of low back pain prevalence throughout the follow-up. Analysis showed a weak trend of decreasing low back pain with moderate/high physical activity levels, but this association was not significant.
Low back pain decreased during follow-up with baseline as reference. Findings in our study did show non-significant trends of reduced low back pain with increased leisure time physical activity. Still, we could not support the theory of moderate/high levels of physical activity acting protective against low back pain in young adults entering working life. Our results, in combination with previous relevant research, cannot support a clear relationship between physical activity and low back pain for young adults. Thus, recommendations regarding effect of physical activity on reducing low back pain for this group are not clear.
年轻人休闲时间身体活动与腰痛之间的关联尚不清楚，需要前瞻性证据。本研究在一群从学校过渡到工作生活的年轻人中，考察了腰痛的病程以及腰痛与休闲时间身体活动之间的关联。
对420名最初是美发、电气安装和媒体/设计专业学生的受试者进行了6.5年的腰痛和休闲时间身体活动监测。在随访期间，使用线性混合模型分析来研究身体活动与腰痛之间的关联。
腰痛受时间的显著影响，总体而言，在整个随访期间腰痛患病率呈下降趋势。分析显示，中等/高强度身体活动水平下腰痛有微弱的下降趋势，但这种关联不显著。
以基线为参照，随访期间腰痛有所减轻。我们的研究结果确实显示，随着休闲时间身体活动增加，腰痛有不显著的下降趋势。然而，我们无法支持中等/高强度身体活动对进入工作生活的年轻人腰痛有预防作用这一理论。我们的结果与之前的相关研究相结合，无法支持年轻人身体活动与腰痛之间存在明确关系。因此，关于身体活动对该群体减轻腰痛的作用的建议尚不明确。
