Objective:
To systematically review the literature regarding non-pharmacological inteventions for improving sleep quality and insomnia during pregnancy.
Methods:
An electronic search strategy was conducted using several online databases (CINAHL, PubMed, Medline, Index to Chiropractic Literature) from inception to March 2013. Inclusion criteria consisted of studies evaluating non-pharmacological interventions, published in English in a peer reviewed journal, and assessed sleep quality or insomnia. The full text of suitable articles was reviewed by the authors, and scored using a risk of bias assessment.
Results:
160 articles were screened and seven studies met the inclusion criteria in the form of three prospective RCTs, one prospective longitudinal trial, one experimental pilot study, and two prospective quasi-randomized trials. Quality scores ranged from five to eight out of twelve on the risk of bias scoring criteria.
Conclusions:
Exercise, massage, and acupuncture may be associated with improved sleep quality during pregnancy, however, due to the low quality and heterogeneity of the studies yielded, a definitive recommendation cannot be made. Further higher quality research is indicated.
