Factors Associated with Poor Glycemic Control Amongst Rural Residents with Diabetes in Korea

(1) Background: Glycemic control is an effective way to reduce the cardiovascular complications of diabetes. The purpose of this study was to identify the factors associated with poor glycemic control amongst rural residents with diabetes in Korea. (2) Methods: This cross-sectional analysis was conducted amongst a total of 522 participants who had completed baseline health examinations for the Korean Genome and Epidemiology Study (KoGES) Rural Cohort from 2005 to 2011. The subjects were divided into two groups: the good glycemic control group (GCG) (glycosylated hemoglobin (HbA1C) < 7%) and the poor GCG (HbA1C >= 7%). Logistic regression was used to examine the role of sociodemographics, health-related behavior, comorbidity and diabetes-related and clinical factors in poor glycemic control amongst rural residents with diabetes. (3) Results: In total, 48.1% of participants were in the poor GCG. Poor GCG was significantly associated with drinking (odds ratio (OR) = 0.42, 95% CI = 0.24-0.71), lack of regular physical activity (OR = 1.68, 95% CI = 1.03-2.76), fasting blood glucose (FBG) > 130 mg/dL (OR = 7.80, 95% CI = 4.35-13.98), diabetes for > 7 years (OR = 1.79, 95% CI = 1.08-2.98), cholesterol >= 200 mg/dL (OR = 1.73, 95% CI = 1.05-2.84) and positive urine glucose (OR = 6.24, 95% CI = 1.32-29.44). (4) Conclusion: Intensive glucose control interventions should target individuals amongst rural residents with diabetes who do not engage in regular physical activity, have been diagnosed with diabetes for more than seven years and who have high fasting-blood glucose, high cholesterol levels and glucose-positive urine.

Automated summary

Among rural residents with diabetes in Korea, poor glycemic control is significantly associated with factors such as drinking, lack of regular physical activity, high fasting blood glucose, longer diabetes duration, high cholesterol levels, and glucose-positive urine. Intensive glucose control interventions are suggested for individuals with these characteristics.
