Prevalence of Dyslipidemia among Korean Adults: Korea National Health and Nutrition Survey 1998-2005

Abstract

BackgroundDyslipidemia is a disorder of lipid metabolism, including elevated total cholesterol, elevated triglyceride, elevated low density lipoprotein cholesterol (LDL-C), and decreased high density lipoprotein cholesterol (HDL-C). The objective of this study was to investigate recent changes in the prevalence of dyslipidemia and also the rates of awareness, treatment, and control of dyslipidemia among Korean adults.MethodsDyslipidemia is defined according to the National Cholesterol Education Program-Adult Treatment Panel III as total cholesterol ≥240 mg/dL, LDL-C ≥160 mg/dL, HDL-C <40 mg/dL, and triglyceride ≥200 mg/dL. The prevalence of dyslipidemia was estimated for adults aged ≥20 years using the Korea National Health and Nutrition Survey (KNHANES) in 1998 (n=6,923), 2001 (n=4,882), and 2005 (n=5,323). Rates of awareness, treatment and control of dyslipidemia were calculated for adults aged ≥30 years using the KNHANES in 2005 (n=4,654).ResultsThe prevalence of dyslipidemia (aged ≥20 years) increased from 32.4% in 1998 to 42.6% in 2001 and 44.1% in 2005. Compared with the KNHANES in 1998, the prevalence of dyslipidemia was 47% (95% confidence interval [CI], 35% to 59%) higher in 2001 and 61% (95% CI, 49% to 75%) higher in 2005. In 2005, only 9.5% of people with dyslipidemia were aware of the disease, 5.2% used lipid-lowering medication, and 33.2% of patients with treatment reached treatment goals.ConclusionThe prevalence of dyslipidemia in Korea gradually increased between 1998 and 2005. These findings suggest that more intense efforts for the prevention and treatment of dyslipidemia may lead to further improvement in the management of dyslipidemia.

Epidemiological analysis of dyslipidemia in adults of three ethnicities in Xinjiang, China

“…The prevalence rates of high TC of all 3 ethnicities surveyed in the present study are lower than those of residents of the U.S. (16.2%) (Miller et al, 2011) and South Korea in 2005 (8.7%) (Lee et al, 2012) but higher than that of residents in China aged ≥18 years in 2010 (3.3%). This may be related to the high proportion of residents consuming a high-fat diet in this area.…”

Association of Body Mass Index with Dyslipidemia among the Government Staff of Kermanshah, Iran: A Cross-Sectional Study

“…In contrast, in Germany and United States, women are involved more in the disease (24,25). Most studies have reported results similar to ours (26,27). This might be due to the higher smoking rate in men, whose physical activity is lower and overall/abdominal obesity is higher, resulting in the increased levels of blood lipids (28).…”

Low bone mineral density is associated with dyslipidemia in South Korean men: The 2008–2010 Korean National Health and Nutrition Examination Survey

“…In particular, the prevalence of dyslipidemia has been shown to be higher in men than in women, with values of 38.4% in 1998 and 54.5% in 2005 [21]. The prevalence of osteoporosis in men is also increasing in South Korea [22].…”
