Educational disparities in distribution of cardiovascular risk factors and quality of care in korean adults: Korean national health and nutrition survey IV

Abstract

Background: The purpose of this study was to investigate how educational status influences cardiovascular risk factors and care of diabetes mellitus and hypertension. Methods: From Korean National Health and Nutrition Survey IV, we obtained survey results of 6,835 men and 9,067 women more than 30 years old. We performed multivariate logistic regression to compare cardiovascular risk factors and care of hypertension and diabetes respective to educational status. Results: There were disparities in cardiovascular risk factors by educational status. In men, impaired fasting glucose, high triglyceride, and smoking were less frequently found in the highest educated group than in the middle educated group. In women, the prevalence of abdominal obesity, impaired fasting glucose, high blood pressure, high triglyceride, and metabolic syndrome among the highest educated group were significantly lower. The proportion of those with proper physical activity in the highest educated group was found to be less than that of the middle educated group, regardless of gender. For care of diabetes mellitus and hypertension, disease recognition and treatment were lower among the lowest educated group in men, while these disparities were not shown in women. Instead, the lowest educated group in diabetic women received screening exams for eye and kidney complications less than the middle education group. In both genders, the high education group had a higher chance of receiving education about diabetes mellitus. Conclusion: There were educational disparities in cardiovascular risk factors and care of hypertension and diabetes mellitus. The disparities were found to be different by gender. © 2013 The Korean Academy of Family Medicine.
