UPDATES FROM THE COCHRANE COMPLEMENTARY MEDICINE FIELD

As part of the Consortium's role in supporting the NCCAM grant to the Cochrane CAM Field group at the University of Maryland, we will now be including a regular "Cochrane CAM Update" in the Consortium News. Here is the abstract from a recent review of "Music for insomnia in adults" by Jespersen and colleagues. A pdf of the full abstract of this review can be found by clicking here. More information on the Cochrane CAM Field as well as summaries of other recent reviews is available at http://www.compmed.umm.edu/cochrane_about.asp

Jespersen KV, Koenig J, Jennum P, Vuust P. Music for insomnia in adults. Cochrane Database of Systematic Reviews 2015, Issue 8. Art. No.: CD010459. DOI: 10.1002/14651858.CD010459.pub2.

This review assessed the effects of listening to music on insomnia in adults and the impact of factors that may influence the effect. The authors included six randomized and quasi-randomized trails comprising a total of 314 participants. The studies examined the effect of listening to pre-recorded music daily, for 25 to 60 minutes, for a period of three days to five weeks.

Results: The results of a random-effects meta-analysis revealed an effect in favor of music listening (mean difference (MD) -2.80; 95% confidence interval (CI) -3.42 to -2.17; Z = 8.77, P < 0.00001; moderate-quality evidence). The size of the effect indicates an increase in sleep quality of the size of about one standard deviation in favor of the intervention compared to no treatment or treatment-as usual. Only one study (N = 50; low-quality evidence) reported data on sleep onset latency, total sleep time, sleep interruption, and sleep efficiency. However, It found no evidence to suggest that the intervention benefited these outcomes. None of the included studies reported any adverse events.

Conclusions: The findings of this review provide evidence that music may be effective for improving subjective sleep quality in adults with insomnia symptoms. The intervention is safe and easy to administer. More research is needed to establish the effect of listening to music on other aspects of sleep as well as the daytime consequences of insomnia.
