Previous meta-analytic results showed beneficial effects of meditation interventions for cortisol levels. In the present meta-analysis we tested whether effects are larger for those who might be in need of such stress reduction programs due to a risk for elevated cortisol levels as compared to no-risk samples. We included RCTs that measured change in cortisol levels. Based on 10 studies using blood samples meditation interventions had a significant, medium effect from pre-to post-test compared to the control group. Upon closer inspection, this effect was only present for at-risk samples, that is, patients with a somatic illness. In the 21 studies using saliva samples the effect was small and not significant, but there was a marginally significant effect for groups living in stressful life situations. This pattern may suggest that that meditation interventions are most beneficial for at-risk populations. These interventions might provide people with strategies of stress management that can contribute to well-being. Preliminary results suggest that benefits of meditation interventions might not fade with time.
先前的荟萃分析结果表明，冥想干预对皮质醇水平有有益影响。在本次荟萃分析中，我们测试了对于那些由于皮质醇水平升高的风险而可能需要这种减压计划的人，与无风险样本相比，干预效果是否更大。我们纳入了测量皮质醇水平变化的 RCT 研究。基于 10 项使用血液样本的研究，与对照组相比，冥想干预在前后测试中有显著的中等效果。进一步观察发现，这种效果仅存在于有风险的样本中，即患有躯体疾病的患者。在使用唾液样本的 21 项研究中，效果较小且不显著，但在生活在压力环境下的群体中，效果有一定的显著性。这种模式可能表明，冥想干预对高危人群最有益。这些干预措施可能为人们提供压力管理策略，有助于提高幸福感。初步结果表明，冥想干预的益处可能不会随着时间的推移而消失。
