Men’s Sheds as Community-based Health Promotion for Men Aged 50 Plus (MASH): Protocol for a Mixed-methods Systematic Review

Background Men are less likely to participate in health promotion. One approach to reach men is the concept of men's sheds. This community-based health promotion concept brings older men together to engage in joint activities. Prior research revealed various health-related effects of men's sheds, such as benefits for well-being and mental health. To strengthen the current evidence base of men's sheds, a mixed-methods systematic review analysing the association between participation and self-rated health, subjective well-being, and social isolation will be conducted. Moreover, information on how to successfully implement men's sheds will be gathered. Methods This mixed-methods systematic review will follow the guidelines of the Joanna Briggs Institute (JBI). The databases MEDLINE (via PubMed), Scopus, Web of Science, and OpenGrey and the websites of men's sheds associations will be searched for publications. Additionally, a hand search in the reference lists of the included publications will be conducted. Qualitative and quantitative studies published in English, German, or French will be considered for inclusion. The quality of the selected studies will be assessed using the JBI critical appraisal checklists. Following the convergent integrated approach, quantitative data will be transformed into textual descriptions, and subsequently combined with data from qualitative studies as well as from the qualitative components of mixed-methods studies in a simultaneous data synthesis. Discussion The results of this systematic review will lead to a comprehensive understanding of the current evidence base regarding the effectiveness of men's sheds. Furthermore, they will provide useful implications for the implementation of men's sheds. Systematic review registration PROSPERO CRD42020219390.
