Background: The patients with metabolic syndrome had
shown low high density lipoprotein-cholesterol
(HDL-C) and smoking had been reported to be an
independent risk factor for low HDL-C. This study aimed to
study the association of smoking status and low HDL-C in
general population of Korea.
Methods: Frequency analysis and descriptive statistics for
general characteristics and chi-square test for the
association of smoking status and low HDL-C were used.
Then, logistic regression analyses for the effect of
smoking on low HDL-C and general linear method for HDL-
C estimates were used.
Results: Univariate regression showed that smoking status
showed an association with low HDL-C. Prevalence
of low HDL-C was 29.4±0.3% of Korean males in their
twenties or over, and low HDL-C possibilities of current
and past-smokers compared with non-smokers were odds
ratio 1.345 and 1.123 respectively. After adjustments
with sociodemographic factors, physical activity, body mass
index (BMI), and age, the low HDL-C possibility
of current-smokers was 1.328 times higher and for past-
smokers was 0.892 times than non-smokers
(P<0.05). The HDL-C concentration of current-smokers was
1.009 mg/dL lower than non-smokers', whereas
that of past-smokers' was 0.478 mg/dL higher than non-
smokers'. HDL-C concentration decreased 0.922
mg/dL for every 1 unit of BMI increase and 0.080 mg/dL for
every 1-year age increase (P<0.05).
Conclusions: In this study using general population, HDL-C
showed significant association with smoking
status. The occupation, BMI and age also had significant
associations. Conclusively, the possible strategies to
maintain serum HDL-C include cessation of smoking,
increase of physical exercise, and weight loss.
