%X An expanding number of mind-body therapies are being used to reduce the psychological burden of peoples living with human immunodeficiency virus (HIV). However, the effects on the immune system and mental health varied among studies.
This meta-analysis was conducted to summarize the randomized controlled trials to draw comprehensive conclusions regarding the psycho-immunological efficacy.
Random-effects models were used to assess the outcome of interest. Egger's tests were used to identify publication bias. Subgroup and meta-regression were used to explore potential moderators. This review was registered on the PROSPERO database (CRD42019148118).
Nineteen randomized controlled trials with a total sample size of 1,300 were included in this meta-analysis. Regarding immune system outcome, mind-body therapy significantly improved CD4 T-cell counts (Cohen's d = 0.214, p = .027) and maintained (0.427, p = .049). In addition, baseline CD4 T-cell counts and years since HIV diagnosis significantly moderated the efficacy of mind-body practices on CD4 improvement (all ps < .001). Regarding mental health outcome, mind-body therapy significantly reduced stress, depression, and anxiety symptoms (0.422, p < .001; 0.506, p < .001, and 0.709, p < .001, respectively) while improving quality of life (0.67, p < .001).
Meditation/yoga intervention could result in potential benefits with regard to improved CD4 T-cell counts immediately after the intervention and at long-term follow-up, while also improving their mental health. The cost-effective meditation/yoga intervention should be integrated into routine care for people living with HIV, especially for those with lower CD4 baseline and fewer years since diagnosis.
