Abstract

Background: Increased body fat was associated with
insulin resistance, glucose and lipid metabolism, and
blood pressure and non-exercise is risk factor for
metabolic syndrome. But, the studies considering both
body fat and exercise were lacking in Korea. We,
therefore, studied relationship between exercise, body fat
and metabolic syndrome among Korean.
Methods: In this study, the subjects included 9,234
(Male; 5,358 Female; 3,876) who had visited one health
promotion center from March, 2007 to February, 2008
and their age range is 20~79 years. Following an
overnight fasting, blood samples taken from antecubital
vein were used for the determination of the blood TG
(Triglyceride), HDL (High density lipoprotein), LDL (Low
density lipoprotein). Body mass index (kg/m2), body fat
percentage, and waist circumference were measured as
obesity indices.
Results: Over body fat (Male ≥ 20%, Female ≥ 30%)
was independently risk factor for metabolic syndrome,
from 30th to 60th, and both over body fat and non-exercise
were independently risk factor for metabolic syndrome in
50th (Male; non-exercise, OR = 1.397, P = 0.039, over
body fat, OR = 7.215, P < 0.001; Female; non-exercise,
OR = 1.831, P = 0.002, over body fat, OR = 3.529, P <
0.001). As based on normal body fat group with doing
exercise, over body fat group with not doing exercise,
over body fat group with doing exercise and normal body
fat group with not doing exercise were showed the
increase of metabolic syndrome in 50th, respectively, OR
= 8.304, P < 0.001; OR = 5.624, P < 0.001; OR = 0.875,
P = 0.791 in male, OR = 8.127, P < 0.001; OR = 4.894,
P < 0.001; OR = 2.739, P = 0.030 in female. In pearson
chi-square, exercise was showed to decrease 27% of body fat percentage in male (P = 0.019) and 28% of that in
female (P = 0.019).
Conclusion: Body fat was more contributed to metabolic
syndrome than exercise.
