Effectiveness of Multilevel and Multidomain Interventions to Improve Glycemic Control in U.S. Racial and Ethnic Minority Populations: A Systematic Review and Meta-analysis.

BACKGROUND: Racial and ethnic disparities in type 2 diabetes outcomes are a major public health concern. Interventions targeting multiple barriers may help address disparities. PURPOSE: To conduct a systematic review and meta-analysis of diabetes self-management education (DSME) interventions in minority populations. We hypothesized that interventions addressing multiple levels (individual, interpersonal, community, and societal) and/or domains (biological, behavioral, physical/built environment, sociocultural environment, and health care system) would have the greatest effect on hyperglycemia. DATA SOURCES: We performed an electronic search of research databases PubMed, Scopus, CINAHL, and PsycINFO (1985-2019). STUDY SELECTION: We included randomized controlled trials of DSME interventions among U.S. adults with type 2 diabetes from racial and ethnic minority populations. DATA EXTRACTION: We extracted study parameters on DSME interventions and changes in percent hemoglobin A1c (HbA1c). DATA SYNTHESIS: A total of 106 randomized controlled trials were included. Twenty-five percent (n = 27) of interventions were exclusively individual-behavioral, 51% (n = 54) were multilevel, 66% (n = 70) were multidomain, and 42% (n = 45) were both multilevel and multidomain. Individual-behavioral interventions reduced HbA1c by -0.34 percentage points (95% CI -0.46, -0.22; I2 = 33%) (-3.7 [-5.0, -2.4] mmol/mol). Multilevel interventions reduced HbA1c by -0.40 percentage points (95% CI -0.51, -0.29; I2 = 68%) (-4.4 [-5.6, -3.2] mmol/mol). Multidomain interventions reduced HbA1c by -0.39 percentage points (95% CI -0.49, -0.29; I2 = 68%) (-4.3 [-5.4, -3.2] mmol/mol). Interventions that were both multilevel and multidomain reduced HbA1c by -0.43 percentage points (95% CI -0.55, -0.31; I2 = 69%) (-4.7 [-6.0, -3.4] mmol/mol). LIMITATIONS: The analyses were restricted to RCTs. CONCLUSIONS: Multilevel and multidomain DSME interventions had a modest impact on HbA1c. Few DSME trials have targeted the community and society levels or physical environment domain. Future research is needed to evaluate the effects of these interventions on outcomes beyond HbA1c.

A socioecological perspective to contraceptive access for women experiencing homelessness in the United States.

OBJECTIVE: Although persons who are pregnancy-capable and experiencing homelessness may have a strong desire to avoid pregnancy, they face unique barriers to contraception. This multimethod qualitative study aimed to identify preferences for, barriers to, and facilitators of contraceptive access and use among women experiencing homelessness in the United States using a systems perspective. STUDY DESIGN: We conducted semistructured interviews with women experiencing homelessness (n = 19), healthcare providers (n = 6), and social service providers (n = 6). We recruited participants from community-based, housing, and medical organizations in North Texas in the United States. Two coders conducted thematic analysis and reached consensus for codes. RESULTS: Women participants were in emergency shelter, unsheltered, or transitional/rapid rehousing. We stratified themes using the Socioecological Framework to illustrate factors affecting contraception access at individual, interpersonal, organizational and community, and societal levels. Notable results include women's preferences for long-acting reversible contraception, difficulties healthcare providers face in initiating contraceptive counseling, and the underutilized role of social service providers in reproductive healthcare. Insurance policies, connections between health clinics and community organizations, and organizational priorities both facilitated and hindered women experiencing homelessness's access to women's healthcare services. CONCLUSION: This study identified opportunities throughout the healthcare and social service systems to support contraceptive access for women experiencing homelessness. Future interventions should strengthen and leverage these connections to promote access among this vulnerable population with the goal of supporting reproductive autonomy. IMPLICATIONS: This study explored the reproductive health needs of women experiencing homelessness. Multilevel interventions, such as interdisciplinary care, patient-centered approaches, and an emphasis on health literacy, are needed to adequately provide the preferred methods of contraception for women experiencing homelessness, thus enabling reproductive autonomy for this population.
