Use of Intersectionality Theory in Interventional Health Research in High-Income Countries: A Scoping Review

Background: Intersectionality theory posits that considering a single axis of inequality is limited and (dis)advantage on multiple axes simultaneously needed. The extent to which intersectionality has been used within interventional health research not systematically examined. This scoping review aimed map out the use intersectionality. It explores when designing implementing public interventions, or analysing impact these interventions. Methods: We undertook systematic searches Medline Scopus from inception through June 2021, with key search terms including “intersectionality”, “interventions” “public health”. References were screened those using primary data high-income countries included relevant synthesised. Results: After screening 2108 studies, we 12 studies. Six studies qualitative focused alcohol substance abuse (two studies), mental general promotion (one study) housing interventions study). three quantitative examined studies) smoking cessation study), while mixed-method sexual exploitation was primarily analyse intervention effects (eight but also for design (three one study it both analysis.

Intersectional frameworks formulate specific questions assess differences in outcomes intersectional markers identity. Analytical recommended approaches improve future treatments structure focus power structural dynamics. Conclusions: yet research, either Conditions such as have more intersectionality, disability are particularly sparse. lack our suggests theoretical methodological advancements need be made order increase engagement health.
