Background: The relationship between religiosity/spirituality and physical health has been the subject of growing interest in epidemiological research. We systematically reviewed prospective observational cohort studies of the association between this potentially protective psychological factor and mortality using meta-analytic methods. Methods: We searched general bibliographic databases: Medline, PsycINFO, Web of Science and PubMed (up to 20 March, 2008). Two reviewers independently extracted data on study characteristics, quality, and estimates of associations. Random effects meta-analyses, subgrouping, and sensitivity analysis were performed. Results: There were 69 studies (28 articles) and 22 studies (11 articles) investigating the association between religiosity/spirituality and mortality in initially healthy populations and diseased populations, respectively. The results of the meta-analyses showed that religiosity/spirituality was associated with reduced mortality in healthy population studies (combined hazard ratio = 0.82, 95% CI = 0.76–0.87, p Conclusions: The current review suggests that religiosity/spirituality has a favorable effect on survival, although the presence of publication biases indicates that results should be interpreted with caution.
