The Association between Physical Activity, Sleep Duration and Incidence Risk of Dyslipidemia in Korean Adults : Korean Genome and Epidemiology Study(2001-2012)

Abstract

The purpose of this study was to analyze the effect on the occurrence of dyslipidemia and to clarify its association with physical activity and sleep duration. This study investigated a total of 3,498 among 10,030 adults(51.7±9.1 years of age) in the Korean Genomic Epidemiology Study(KoGES) communitybased cohort study for 12 years between 2001 and 2012. The results showed that the level of sleep duration and physical activity showed a statistically significant relationship based on these distribution characteristics(p<.05). Three models were constructed to analyze the association between physical activity and the incidence risk of dyslipidemia according to adjusting variables. The group with high levels of physical activity had significantly lower incidence risk of dyslipidemia(p<.001) compared to the intermediate level of physical activity and the low physical activity group. Also, there were three models to examine the incidence risk of dyslipidemia in accordance to sleep duration with adjusting variables. Those models presented that more than 8 hours of sleep duration had a higher incidence risk of dyslipidemia than the other two groups(i.e., 6 to 8 hours, below 6 hours/day; p<.05). In conclusion, high physical activity had an effect of statistically significant reduction in the incidence risk of dyslipidemia. Sleep duration between 6 and 8 hours a day could have the most effective impact on reducing the incidence risk of dyslipidemia. Future research should be conducted to investigate more accurately physical activity and sleep conditions through systematic development of survey investigation.
