Abstract

Purpose
The purpose of this study was to examine the relationship between sedentary behavior measured by accelerometer and cardiovascular disease risk factors from Korea National Health and Nutrition Examination Survey 2014–2015.
Methods
The participants included in this study volunteered to wear accelerometer (n=1,407). Ordinal logistic regression was used to examine the relationship between sedentary time or sedentary breaks and cardiovascular disease risk factors. Odds ratios and 95% confidence intervals were calculated for the relationship. Covariates were sex, age, educational status, alcohol, smoking, socioeconomic status, body mass index, calorie intake, physical activity, and accelerometer wear time.
Results
The group with the most sedentary time had significantly greater odds of having dyslipidemia (odds ratio, 2.47; 95% confidence interval, 1.54–3.94) compared to the least. There were no other significant relationships between sedentary behavior (sedentary time, sedentary break) and risk factors.
Conclusion
The only significant relationship found in this study was that between sedentary time and dyslipidemia.
