Systematic review: Individual‐level factors and social determinants of health impacting sleep health in individuals with inflammatory bowel disease

Abstract Aim To examine the individual‐level factors and social determinants of health (SDOH) linked to sleep health among individuals with inflammatory bowel disease (IBD). Design Systematic review without meta‐analysis. Data Sources Four databases (PubMed, Web of Science, CINAHL and PsycINFO) were searched in February 2022. Review Methods Databases were searched with keywords related to IBD and sleep. The review was conducted per the PRISMA protocol. The checklist for analytical cross‐sectional studies published by the Joanna Briggs Institute was used for quality appraisal. Factors were organized by individual, social and societal levels according to the social–ecological model of sleep health. Results In the review, 45 studies were identified and synthesized. All studies examined individual‐level factors with sleep, with age being the most common factor studied. Only nine studies considered a social determinant of health which included marital status, number of children, education level, annual income, employment status, work tenure, type of employment, area of residence, minority status/ethnicity and COVID‐19. However, the source of information for the social determinant of health was not clearly defined for more than half of these studies. Conclusion Although IBD sleep research has explored individual‐level factors (i.e. age) that impact sleep health, there is a lack of information on the SDOH that can contribute to sleep health. Impact This review provides insight into the different factors that have been examined in IBD sleep research. By determining the SDOH that impact sleep, nursing research can inform sustainable and tailored interventions that focus on changing behaviour and improving sleep of individuals of varying backgrounds and life experiences. There is a continued need for nurses in practice and research to explore the SDOH that influence health outcomes and the daily lives of those with IBD.
