Background: A low level of high-density lipoprotein-cholesterol (HDL-C) is well known as an important cardiovascular
risk factor which is closely associated with physical activity levels. However, there is a very few
studies conducted on relationship between physical activity and HDL-C status among Korean adults.
Methods: We selected total 22,294 people aged 19 to 69 years old who had not taken lipid lowering agents from
the 2005 Korea National Health and Nutrition Examination Survey (NHANES) data. The population was classified
into three groups using the criteria for HDL-C of Adult Treatment Panel III. The relationship between the physical
activity and HDL-C was investigated and the amount of physical activity levels of the three HDL-C groups were obtained
with analysis of covariance with adjustments for various factors influencing the physical activity levels.
Results: After adjusted for various factors influencing HDL-C, physical activity is significantly associated with
HDL-C. As physical activity is increased, HDL-C is much higher (P<0.001).The physical activity levels were significantly
different among the three HDL-C groups. The amount of physical activity in low HDL-C group was significantly
low compared to high HDL-C group (1653.08±65.31 MET-min/wk vs. 1916.70±102.86 MET-min/wk,
P<0.001).
Conclusions: We confirmed that the amount of physical activity level in low HDL-C group was significantly lower
compared with that of high HDL-C group in Korean adults.
