Abstract 10796: Trends in Control of Weight and Cardiovascular Risk Factors Among US Adults with Type 2 Diabetes Mellitus (T2DM) in the National Health and Nutrition Examination Survey 1999-2008
Background: Most patients with type 2 diabetes (T2DM) suffer from cardiovascular disease-related events with obesity remaining a major challenge in the treatment of patients with T2DM. Through guideline evolutions over the past decade, weight loss and control of HbA1c, blood pressure, and LDL-C have remained key recommendations.
Methods: We examined National Health and Nutrition Examination Survey data from 1999-2008 and evaluated control of HbA1c (<7%), blood pressure (<130/80 mmHg), LDL-C (<100 mg/dl), and body mass index (BMI) (<25 and 30 kg/m2) individually and in combination across the 5 reporting periods. The Cochrane-Armitage test was used to examine trend across time.
Results: 1899 adults (aged ≥ 18yrs) in the US with T2DM across the 5 reporting periods were included. The results of the analyses are shown in the table below. Though control of HbA1c, BP and LDL-C have significantly improved overtime, only one-sixth were at goal for all three factors in the most recent reporting period suggesting significant residual unmet need. Also, there was no improvement made in weight control over the 10 year period. Despite increased emphasis on combined risk factor control in T2DM, only about 3% of US T2DM patients are in control for the combination of all four factors (HbA1c, BP, LDL-C and BMI), with no demonstrable improvement over this time period.
Conclusion: Despite modest improvement over time, only one-sixth of those with Type 2 DM are at goal for HbA1c, BP, and LDL-C, with fewer additionally at normal BMI. Different patient management strategies may be required to address this confluence of risk factors as current efforts have not proved successful.
