based on data from more than 7,000 individuals.

Racial and ethnic disparities in diabetes care remain a pervasive health problem, and minorities including non-Hispanic Blacks and Hispanics experience higher rates of complications, including retinopathy and neuropathy, compared with other groups, Felippe Ottoni Marcondes, MD, of Massachusetts General Hospital, Boston, and colleagues noted in a poster presented at the annual meeting of the Society for General Internal Medicine.
Data from previous studies have shown that diabetes patients who receive guideline-directed preventive care soon after diagnosis can reduce their risk of complications, they said.
To identify disparities in the provision of guideline-directed preventive care, the researchers analyzed data from 7,341 individuals who participated in the National Health Interview Survey from 2011 to 2017. They reviewed associations between race/ethnicity and visits to an eye specialist, a foot specialist, and checks of blood pressure and cholesterol in the past year among individuals diagnosed with diabetes within the past 5 years.
Overall, Hispanics had significantly lower rates of insurance coverage (75.9%), compared with non-Hispanic Whites (93.2%) and non-Hispanic Blacks (88.1%; P < .001).
Hispanics also were significantly less likely than Whites to have had a prior year eye exam (odds ratio, 0.80) and blood pressure check (OR, 0.45), after controlling for variables including age, sex, socioeconomic status, health insurance, general health status, U.S. region, marital status, body mass index, and various comorbidities.
Although insurance coverage mediated 42.8% of the total effect of race/ethnicity on annual eye specialist visits for Hispanics as compared with Whites, there was no significant effect for Blacks, compared with Whites.
COVID concerns impact diabetes disparities
“As the diabetes epidemic continues in the U.S., it is important to bring to the front of the diabetes care conversation racial/ethnic disparities that persisted or have been only partially addressed,” Dr. Marcondes said in an interview. “It is also important to emphasize that patients with diabetes are at higher risk for COVID-19 hospitalizations, complications, and death, and COVID-19 has disproportionately affected racial/ethnic minorities, so racial/ethnic minorities with diabetes have compounded risk of complications not only from diabetes but also from COVID-19.
“Importantly, our study highlights disparities in health care that are likely the product of systemic inequalities in access to care and insurance coverage at a moment when conversations about the race/racism and their health impact are fresh in the minds of public and health policy officials and the general public,” he emphasized.
“Unfortunately, I cannot say that I am surprised by our findings,” Dr. Marcondes said. “We expected to see some differences in the receipt of care for racial/ethnic minorities compared to white individuals for those recently diagnosed with diabetes, and that is exactly what our findings show.”
However, “what was perhaps intriguing is that disparities in the receipt of guideline-directed care were greater for Hispanic compared to White individuals than for Black compared to White individuals,” said Dr. Marcondes. “The causes of these differences are many. Hispanic individuals are less likely than White and Black persons to have insurance coverage.” Other unmeasured factors include language barriers that Hispanic individuals may face, as well as the bias and discrimination experienced by Hispanic and Black individuals alike.
