Measurement and Operationalization of the Social Determinants of Health and Long-Acting Reversible Contraception Use in the U.S.: A Systematic Scoping Review

INTRODUCTION: The objective of this review was to conduct a systematic evaluation of the measurement and operationalization of the social determinants of health in research on long-acting reversible contraception use in the U.S. To contribute to the ongoing refinement of the quality of social determinants of health and long-acting reversible contraception use research, this systematic scoping review examines how social determinants of health are measured and operationalized in studies that examine long-acting reversible contraception initiation and usage at the patient level. METHODS: A detailed search of 5 electronic databases (PubMed, Embase, Web of Science, CINAHL, and PsycINFO) was conducted between December 2020 and January 2021 according to PRISMA guidelines. Determinants were assessed using the Dahlgren and Whitehead model. The protocol and data extraction template were developed a priori. RESULTS: A total of 27 articles representing 26 studies were included in our study. A total of 12 studies were retrospective and cross-sectional in design; the remaining studies were a combination of designs. Healthcare services and health insurance were identified as the most frequently researched categories of determinants. There was wide variation in reported operationalization of race and ethnicity, limited engagement with sexuality, and uneven geographic representation across studies. DISCUSSION: This systematic scoping review is the first, to the best of our knowledge, to focus on the measurement and operationalization of social determinants of health and on current long-acting reversible contraception use research. Future research on the impact of social determinants of health on long-acting reversible contraception use must explore the full range of factors shaping contraceptive decision making and use and focus on equity-informed data collection methods and reporting.
