BACKGROUND Morphological changes of the lumbar spine muscles are not well characterised with ageing. To further the understanding of age-related degeneration of the lumbar spine musculature, normative morphological changes that occur within the paravertebral muscles must first be established. METHODS A systematic review and meta-regressions were conducted adhering to PRISMA guidelines. Searches for published and unpublished data were completed in June 2019. RESULTS Searches returned 4781 articles. 34 articles were included in the quantitative analysis. Three-level meta-analyses showed age-related atrophy (r = -0.26; 95% CI: -0.33, -0.17) and fat infiltration (r = 0.39; 95% CI: 0.28, 0.50) in the lumbar paravertebral muscles. Degenerative changes were muscle-specific and men (r = -0.32; 95% CI: -0.61, 0.01) exhibited significantly greater muscle atrophy than women (r = -0.24; 95% CI: -0.47, 0.03). Imaging modality, specifically ultrasound, also influenced age-related muscle atrophy. Measurements taken across all lumbar levels revealed the greatest fat infiltration with ageing (r = 0.58, 95% CI: 0.35, 0.74). Moderators explained a large proportion of between-study variance in true effects for muscle atrophy (72.6%) and fat infiltration (79.8%) models. CONCLUSIONS Lumbar paravertebral muscles undergo age-related degeneration in healthy adults with muscle, lumbar level and sex-specific responses. Future studies should use high-resolution imaging modalities to quantify muscle atrophy and fat infiltration.

年龄相关的腰椎旁肌肉变性:系统评价和三级元回归。

背景技术随着年龄的增长,腰椎肌肉的形态变化不能很好地表征。为了进一步了解与年龄相关的腰椎肌肉组织变性,必须首先确定椎旁肌肉内发生的规范性形态变化。方法遵循PRISMA指南进行系统回顾和荟萃回归。搜索已发布和未发布的数据已于2019年6月完成。结果搜索返回了4781篇文章。定量分析包括34篇文章。三级荟萃分析显示腰椎旁肌肉中与年龄相关的萎缩(r = -0.26; 95%CI:-0.33,-0.17)和脂肪浸润(r = 0.39; 95%CI:0.28,0.50)。退行性变是肌肉特异性和男性(r = -0.32; 95%CI:-0.61,0。01)表现出比女性明显更大的肌肉萎缩(r = -0.24; 95%CI:-0.47,0.03)。成像方式,特别是超声,也影响了与年龄有关的肌肉萎缩。在所有腰椎水平上进行的测量显示,随着年龄的增长,脂肪的浸润最大(r = 0.58,95%CI:0.35,0.74)。主持人解释了在肌肉萎缩(72.6%)和脂肪浸润(79.8%)模型的真实效果中,研究之间的很大一部分差异。结论在健康成年人中,腰椎旁肌肉会发生与年龄有关的变性,并具有肌肉,腰椎水平和性别特异性反应。未来的研究应使用高分辨率的成像方式来量化肌肉萎缩和脂肪浸润。在所有腰椎水平上进行的测量显示,随着年龄的增长,脂肪的浸润最大(r = 0.58,95%CI:0.35,0.74)。主持人解释了在肌肉萎缩(72.6%)和脂肪浸润(79.8%)模型的真实效果中,研究之间的很大一部分差异。结论在健康成年人中,腰椎旁肌肉会发生与年龄有关的变性,并具有肌肉,腰椎水平和性别特异性反应。未来的研究应使用高分辨率的成像方式来量化肌肉萎缩和脂肪浸润。在所有腰椎水平上进行的测量显示,随着年龄的增长,脂肪的浸润最大(r = 0.58,95%CI:0.35,0.74)。主持人解释了在肌肉萎缩(72.6%)和脂肪浸润(79.8%)模型的真实效果中,研究之间的很大一部分差异。结论在健康成年人中,腰椎旁肌肉会发生与年龄有关的变性,并具有肌肉,腰椎水平和性别特异性反应。未来的研究应使用高分辨率的成像方式来量化肌肉萎缩和脂肪浸润。结论在健康成年人中,腰椎旁肌肉会发生与年龄有关的变性,并具有肌肉,腰椎水平和性别特异性反应。未来的研究应使用高分辨率的成像方式来量化肌肉萎缩和脂肪浸润。结论在健康成年人中,腰椎旁肌肉会发生与年龄有关的变性,并具有肌肉,腰椎水平和性别特异性反应。未来的研究应使用高分辨率的成像方式来量化肌肉萎缩和脂肪浸润。
