Key findings Pooled analysis of two trials indicated that meditation significantly improved disease-specific quality of life compared with control (SMD 0.40, 95% CI 0.05-0.76), while pooled results from all four trials showed an uncertain effect on FEV1 (SMD -0.67, 95% CI -2.17 to 0.82). Individual trials suggest meditation may reduce perceived stress and short-term rescue medication use, but the authors note that two of four studies were of poor quality and call for further trials.

Abstract

To conduct a comprehensive review and meta-analysis of the effectiveness of meditation on a variety of asthma outcomes. We searched MEDLINE, EMBASE, CINAHL, PsycINFO and AMED in June 2016 to identify randomized controlled trials (RCTs) investigating the effectiveness of meditation in adults with asthma. No restriction was put on language or year of publication. Study quality was assessed using The Cochrane Risk of Bias Assessment Tool. Meta-analysis was carried out using RevMan 5.3. Four RCTs involving 201 patients met the inclusion criteria. Quality of studies was inconsistent with only one study reporting adequate allocation concealment. Disease-specific quality of life was assessed in two trials; a pooled result involving 62 intervention and 65 control participants indicated a significant improvement in quality of life in the meditation group compared to the control group (SMD 0.40, 95% CI 0.05-0.76). A pooled result from all four studies indicated the uncertain effect of meditation in forced expiratory volume in 1 s (FEV1) (SMD -0.67, 95% CI -2.17 to 0.82). Results from the individual trials suggest that meditation may be helpful in reducing perceived stress and the use of short-term rescue medication. Our review suggests that there is some evidence that meditation is beneficial in improving quality of life in asthma patients. As two out of four studies in our review were of poor quality, further trials with better methodological quality are needed to support or refute this finding.
