medwireNews: Significant progress has been made since 2005 in reducing cardiovascular (CV) risk factors among Korean adults diagnosed with diabetes, report researchers.
However, the proportion of individuals achieving glycemic, blood pressure, and low-density lipoprotein (LDL) cholesterol targets remains far from optimal, say Cheol-Young Park (Sungkyankwan University, Seoul) and colleagues.
Although the number of individuals diagnosed with diabetes has steadily increased since 1998, the proportion of those achieving all three of the targets in accordance with American Diabetes Association (ADA) guidelines is still not satisfactory, says the team.
The findings come from a data analysis of the Korean National Health and Nutrition Examination Survey (KNHANES) carried out in the years 1998 (KNHANES I), 2001 (II), 2005 (III), 2007-9 (IV), and 2010 (V).
Previous analysis has shown that the prevalence of diagnosed diabetes did not significantly increase between 1998 and 2005 and less than half of those who were diagnosed achieved the ADA glycated hemoglobin (HbA1c) target of less than 7%. Furthermore, no data were reported on control of CV risk factors hypertension and hyperlipidemia.
As reported in the Journal ofDiabetes Investigation, the current study found that the overall proportion of diagnosed diabetes increased significantly among Korean adults between 1998 and 2010, at 3.2%, 3.6%, 5.2%, 6.2%, and 6.4% in 1998, 2001, 2005, 2007-2009, and 2010, respectively.
"The significant increase in diagnosed diabetes might be explained by a better detection rate and better health education, as well as improved national healthcare system," say Park et al. "Partly, this results from the bi-annual fasting blood glucose testing carried out by the National Health Insurance in Korea for the country's nationals," they explain.
The researchers report that the percentage of those diagnosed with diabetes who achieved the ADA glycemic control target was 42.5% in 2005, compared with 49.1% in 2010. "This represents only approximately half of individuals with diagnosed diabetes, but it is encouraging that there was a significant improvement in glycemic control from 2005 through 2010," they remark.
The percentage of individuals achieving the ADA blood pressure control (<130/80 mmHg) and LDL cholesterol control (<100 mg/dL) targets did increase significantly, from 23.8% and 25.7%, respectively, in 2005 to 54.2% and 47.7%, respectively, in 2010.
However, the proportion of those achieving all three target levels was just 2.7% in 2005 and 8.7% in 2010. "This means that the percentage of those not achieving all three goals was over 90%," write Park and team.
"More aggressive efforts should be made in regards to diabetes treatments to overcome the diverse complications of this disease," they conclude.
