Disparities in diabetes prevalence and management by race and ethnicity in the USA: defining a path forward.

Type 2 diabetes disparities in the USA persist in both the prevalence of disease and diabetes-related complications. We conducted a literature review related to diabetes prevention, management, and complications across racial and ethnic groups in the USA. The objective of this review is to summarise the current understanding of diabetes disparities by examining differences between and within racial and ethnic groups and among young people (aged <18 years). We also examine the pathophysiology of diabetes as it relates to race and ethnic differences. We use a conceptual framework built on the socioecological model to categorise the causes of diabetes disparities across the lifespan looking at factors in five domains of health behaviours and social norms, public awareness, structural racism, economic development, and access to high-quality care. The range of disparities in diabetes prevalence and management in the USA calls for a community-engaged and multidisciplinary approach that must involve community partners, researchers, practitioners, health system administrators, and policy makers. We offer recommendations for each of these groups to help to promote equity in diabetes prevention and care in the USA.

Key Factors for Successful Implementation of HIV Prevention Services by THRIVE Community Collaboratives.

OBJECTIVE: The Targeted Highly Effective Interventions to Reverse the HIV Epidemic (THRIVE) demonstration project created collaboratives of health departments, community-based organizations, and clinical partners to improve HIV prevention services for men who have sex with men (MSM) and transgender women (TGW) of color. We administered an online survey from September 2018 through February 2019 to assess the collaboratives. METHODS: We used a Likert scale to measure agreement on collaborative characteristics. We used Fisher exact tests to compare success ratings by health department employment and funding status. We created a radar chart to compare the percentage agreement on key characteristics of the most and least successful collaboratives. We used a general inductive approach in the qualitative analysis of open-ended question responses. RESULTS: Of 262 survey recipients, 133 responded (51%); 49 (37%) respondents were from health departments. Most respondents (≥70%) agreed that their collaborative is diverse, cooperates, meets regularly, has realistic goals, has effective leadership, and has effective communication. Most respondents (87%) rated their collaborative as successful in implementing HIV prevention services for MSM and TGW of color. Comparison of the most and least successful collaborative found the greatest difference in respondent agreement in the presence of effective leadership, communication, and adequate resources. The most commonly cited challenge in the open-ended questions was inadequate resources. The most commonly cited success was increased provision of services, particularly preexposure prophylaxis. CONCLUSIONS: Community collaboratives were considered successful by most collaborative members and may be an effective part of HIV prevention strategies.

The relationship between excess body weight and the risk of death from unnatural causes.

OBJECTIVE: The purpose is to exam whether excess body weight is associated with an increased risk of death from unnatural causes, particularly, injury. METHOD: We analyzed nationally representative data of 14,453 adults (19 and older) who participated in the third National Health and Nutrition Examination Survey, 1988-1994, and were followed up with vital statuses through December 31, 2006. We used Cox proportional hazard regression to estimate the hazard ratio (HR) of death from all unnatural causes combined and specific ones. Gray's test was performed to assess the equality of cumulative incidence functions between body mass index (BMI) levels. RESULTS: A total of 128 unnatural deaths were recorded during an 18-year follow-up with 193,019 person-years accumulated. Compared with healthy weight participants, a person with excess body weight had a low hazard of death from unnatural causes [HR=1.00 (reference), 0.58 (0.39-0.87), and 0.50 (0.30-0.82) for healthy weight, overweight and obese participants, respectively]. Injuries, including motor vehicle accidents and falls, were the major types of unnatural deaths (n=91, 71% of all unnatural deaths), and the risk of death from injuries was linearly and reversely associated with BMI. The HRs of injury were 1.00 (reference), 0.57 (0.36-0.91), and 0.36 (0.19-0.69) for healthy weight, overweight and obese participants, respectively. All these estimates were obtained after adjustment of socio-demographic variables. DISCUSSION: Excess body weight appears to be associated with a low risk of death from unnatural causes, particularly, injuries. Additional investigations on the mechanism underlying the relationship between BMI and unnatural deaths are warranted.
