OBJECTIVES: To investigate trends in the prevalence of allergic disease over a 9-year period. METHODS: Using National Health Insurance Service (NHIS) data, the annual number of patients with allergic disease was obtained for each regional subdivisions (small cities, counties, and districts) from 2003 to 2011. Annual populations for each sub-region were obtained and used to calculate the standardized prevalence. To compare prevalence within the study period, data was standardized spatially and temporally. For standardization, demographic data was used to obtain the registered population and demographic structure for 2010, which was used to perform direct standardization of previous years. In addition, a geographic information system (GIS) was used to visualize prevalence for individual sub-regions, and allergic diseases were categorized into five groups according to prevalence. RESULTS: The nationwide outpatient prevalence of allergic rhinitis increased approximately 2.3-fold, from 1.27% in 2003 to 2.97% in 2013, while inpatient prevalence also increased approximately 2.4-fold,. The outpatient prevalence of asthma increased 1.2-fold, and inpatient prevalence increased 1.3-fold. The outpatient prevalence of atopic dermatitis decreased approximately 12%, and inpatient prevalence decreased 5%. CONCLUSIONS: There was a large difference between prevalence estimated from actual treatment data and prevalence based on patients' self-reported data, particularly for allergic rhinitis. Prevalence must continually be calculated and trends should be analyzed for the efficient management of allergic diseases. To this end, prevalence studies using NHIS claims data may be useful.

This study was conducted to investigate the status of diabetes education in Korean diabetics and to analyze the association between blood sugar control and diabetes education. A total of 1,904 diabetic patients was classified into two groups (well-controlled group and uncontrolled group) using the 2008-2013 Korean National Health and Nutrition Survey data, and various variables were compared. Of the 1,904 patients, 15.9% had received diabetes education. The uncontrolled group had a low economic level, a high rate of drinking and obesity, and a low rate of moderate exercise. And the rate of drug treatment in the uncontrolled group was high, and the rate of education and nutrition education, and the total number of educations for diabetes were significantly lower than those in the control group. Factors affecting blood glucose control were analyzed drinking (odds ratio [OR], 1.34; 95% confidence interval [CI], 1.06–1.7), moderate exercise (OR, 0.45; 95% CI, 0.34–0.6), overweight and obesity (OR, 1.44; 95% CI, 1.17–1.78), duration of diagnosis (OR, 1.07; 95% CI, 1.05–1.08), treatment method (OR, 2.0; 95% CI, 1.45–2.77), nutritional education (OR, 0.62; 95% CI, 0.46–0.85), and education institution (OR, 0.71; 95% CI, 0.54–0.93). The results of this study support that education on lifestyle management, such as a balanced diet, regular exercise, and normal weight maintenance, is essential for blood glucose control, and patients with long-term treatment need cyclic and continuous education.

OBJECTIVES: The increase in the obesity rate in adult males in Korea is higher than countries in the Organization for Economic Co-operation and Development and other Asian countries. We examined the trends and prevalence of major risk factors for cardiovascular disease by evaluating the weight status amongst adults from 2007 to 2015. METHODS: The study included 37,402 adults, who participated in the Korea National Health and Nutrition Examination Survey. The prevalence trends of cardiovascular disease risk factors were estimated for each body mass index group. RESULTS: From 2007 to 2015, significant increases in the prevalence of hypertension, diabetes, and hypercholesterolemia were observed in normal weight adults (0.03 percentage point (%p), 0.06%p, and 0.13%p, respectively). Amongst the overweight and obese adults, a significant increase in the prevalence of hypercholesterolemia was observed, During this period, the prevalence of smoking decreased amongst obese adults and no significant changes in drinking habits and physical activity were noted across all body mass index groups. CONCLUSION: The prevalence of obesity in Korean adults is increasing, and it is necessary to implement interventions to prevent further weight gain and obesity-associated cardiovascular disease.
