Type 2 diabetes mellitus is prevalent in minority populations in the United States.
In this study, published in the latest issue of the Archives of Internal Medicine, researchers studied the relationship of age to glycemic control, in a predominantly urban African American population with type 2 diabetes.
The research team assessed 2539 patients with type 2 diabetes, who were enrolled in the Grady Diabetes Clinic, Atlanta, between 1991 and 1998.
The team measured patient’s hemoglobin A1c (HbA1c) levels at their initial visit and at follow-up 5 to 12 months later.
Patients were divided into 4 age categories. Less than 30 years, 30 to 49 years, 50 to 69 years, and more than 69 years old.

The researchers also studied the relationship of age to HbA1c level in a primary care clinic.
The team found that at baseline, average HbA1c levels were 9.9%, 9.5%, 9.2%, and 8.8% for the increasing age groups, respectively.
In addition, body mass indexes were 37.8, 33.9, 31.6, and 29.2, respectively.
On follow-up, HbA1c levels improved in all groups, however, there was still a trend for younger patients to have higher levels of HbA1c.
The team found little change in body mass index with time.
However, younger age, longer diabetes duration, higher body mass index, less frequent interval visits, and treatment with oral agents or insulin were associated with a higher HbA1c level at follow-up.
The research team’s findings in a primary care clinic showed that HbA1c level and body mass index were negatively correlated with age.
Dr Imad El-Kebbi’s team concluded, “Our data show a high prevalence of obesity and poor glycemic control in young adult urban African Americans with diabetes”.
