A Mixed-Methods Systematic Review on Syndemics in Rheumatology.

ABSTRACT

OBJECTIVE: We aimed to assess the use of framework and corresponding methodology to document syndemics and its impact in rheumatic and musculoskeletal diseases (RMDs). METHODS: Using a mixed-methods systematic review, studies using the syndemic framework approach for RMDs were identified and published from January 2003 to January 2021. The Joanna Briggs Institute, Cochrane Collaboration, and PRISMA guidelines were followed to search, retrieve, revise, and analyze. RESULTS: A total of 658 potential articles were identified, but only 10 were initially eligible. After a full-text review, 4 were included. Following a full-text review, 2 quantitative, 1 qualitative, and 1 mixed-methods study were included. In the first, network analysis found that RMDs were associated with comorbidities, unhealthy habits, low educational level, living in rural areas, socioeconomic conditions, and health inequality in indigenous communities. In the second, SSEM and cluster analysis demonstrated an association between low back pain and factors, such as comorbidities and indigenous status, among others, in urban/rural communities. The qualitative study examined 3 fishing family generations and reported less syndemic vulnerability. The mixed-methods study focused on osteoarthritis with multimorbidities in African American population, where lack of education added to worsening outcomes. CONCLUSIONS: Even though the insights syndemic studies have given to other areas, its use in rheumatology is scarce. The complexity of the clinical and social determinants related to RMDs makes it necessary to conduct further studies from a syndemic perspective.
