Abstract

|

Background: The present study investigated the association between physical activity and serum gamma-glutamyltransferase (GGT) levels, a factor influencing cardiovascular disease. Serum GGT levels are associated with oxidative stress, and oxidative stress is associated with physical activity intensity and duration. We studied the relationship between exercise and GGT levels in Korean adults.
Methods: Data from the fifth Korean National Health and Nutrition Examination Survey (2010?2011) were used to analyze 10,159 women and men. Subjects were divided into four groups based on the quartile of GGT. Multiple logistic regression analysis was performed after adjusting for age, sex, body mass index, alcohol drinking, income, education, occupation, living alone and presence of diabetes mellitus, hypertension, or dyslipidemia in order to determine the association between physical activity and serum GGT levels.
Results: Walking was significantly associated with serum GGT levels in men. We found a significant association between walking time per week and low GGT levels in men (P for trend ≤0.0001). However, there was no statistically significant relationship between other exercise types and GGT levels, nor was there a statistically significant relationship between exercise type and GGT levels in women. After adjusting for confounders, the odds ratio (95% confidence interval) for serum GGT levels compared with the non-walking group in men was 1.334 (1.076?1.652).
Conclusion: Walking is significantly associated with serum GGT levels in Korean men.
