Religion, Spirituality and Improved Glycemic Control Among People With Type 2 Diabetes: A Systematic Review.

OBJECTIVE This systematic review investigates the association between measures of religiosity or spirituality (R/S) and glycemic control in patients with type 2 diabetes. METHODS A systematic literature review was conducted for all English language articles published between 1966 to August 2022 in six relevant databases: PubMed, PSYCHinfo, CINAHL, ATLA, Scopus, Sociological Abstracts, and the Cochrane Central Register of Controlled Clinical Trials. Search terms for religious variables included, "religion", "religiosity", "spirituality", "religious attendance". Search terms for objective diabetes outcomes included, "diabetes", "hemoglobin A1c", "blood glucose", "glycemic control." The protocol was registered with the International Prospective Register of Systematic Reviews (PROSPERO). RESULTS A total of 758 studies examining correlations between R/S and glycemic control were screened from relevant databases. 40 studies were evaluated for eligibility and inclusion. Eight studies were selected and analyzed. Three studies showed positive associations, two studies showed positive and neutral associations, two studies showed positive and negative associations, and one study showed a neutral association. Limitations included sample sizes and heterogeneity of study designs. CONCLUSION Involvement in religious and spiritual practices may be associated with improved glycemic control in patients with type 2 diabetes. Specific mechanisms for associations may be partially explained by more effective self-management practices, increased positive social contacts, and regular community support. Further research may further clarify significant associations.
