Early detection of type 2 diabetes among older African Americans.

The purpose of this research was to determine whether a group of African Americans who had no diagnosis of type 2 diabetes had elevated blood glucose levels and other risk factors indicative of type 2 diabetes. A convenience sample of 20 African American adults 50 years and older participated in the pilot study. Participants were screened for elevated fasting capillary blood glucose levels and related risk factors such as hypertension, high cholesterol levels, and high body mass index. Frequency data indicated that at least 50% of participants had capillary glucose levels greater than 110 mg/dL. An overwhelming majority of the participants with elevated glucose levels had one or more other risk factors for type 2 diabetes. Evidence-based practice clearly indicates that an early detection and control of type 2 diabetes can prevent complications and also help prevent coronary artery disease.
