Abstract P441: Racial Disparities in the Control Status of Cardiovascular Risk Factors in a Diabetic Underinsured Population
Background: The long term trends in control status of cardiovascular risk factors among type 2 diabetic patients is unclear.
Aim: To investigate the race-specific trend in attainment of the American Diabetes Association (ADA) cardiovascular risk factor control goals of diabetic patients (HbA1c <7.0%, blood pressure <130/80 mmHg, and low-density lipoprotein [LDL] cholesterol <100 mg/dL) from 2001-2009 and to evaluate racial disparities in the percentage at enrollment and the updated mean percentage of successful attainment of the ADA goals in the type 2 diabetic cohort of the Louisiana State University Hospital-based Longitudinal study (LSUHLS).
Methods: We performed a prospective cohort study (2001-2009) on diabetic patients enrolled in the LSUHLS. The study sample included 14,946 African American diabetic patients and 12,758 White diabetic patients who were newly diagnosed with type 2 diabetes between 2001 and 2009. The race-specific percentages of type 2 diabetic patients’ attainment of ADA goals for cardiovascular risk factor control were calculated by using the baseline and follow-up measurements of HbA1c, blood pressure, and LDL-cholesterol levels. Chi-square test was used to test the difference between African American and White patients.
Results: Percentages of people who achieved the target levels of HbA1c, blood pressure, LDL-cholesterol, or all the three were higher among White diabetic patients than among the African American diabetic patients in each of the ten years (2001-2009). The baseline percentages of people who attained none of the three goals, only the HbA1c goal, only the blood pressure goal, only the LDL-cholesterol goal, the HbA1c goal and the blood pressure goal, the HbA1c goal and the LDL-cholesterol goal, the blood pressure goal and the LDL-cholesterol goal, and all the three goals were 23.2%, 27.3%, 5.2%, 13.3%, 6.7%, 15.9%, 3.4%, and 5.1% in African American diabetic patients, and 17.5%, 26.7%, 4.6%, 11.0%, 9.3%, 19.0%, 3.9%, and 8.0% in White diabetic patients, respectively. The updated mean percentages in these subgroups of African American and White participants were similar.
Conclusions: During 2001-2009, this low income diabetic cohort generally experienced improved control of HbA1c and blood pressure. White diabetic patients had better attainment of the ADA cardiovascular risk factor control goals than their African American counterparts.
