Association between Chronic Kidney Disease and Sleep Duration among Jeju Farmers: Safety for Agricultural Injuries of Farmers Cohort Study

ABSTRACT

OBJECTIVES@#This study was conducted to identify the association between sleep duration and chronic kidney disease (CKD) among the agriculture population.@*METHODS@#We utilized the study of Safety for Agricultural Injuries of Famers cohort collected from September 2015 to June 2018, which was data on the health and behaviors of the adult agriculture population on Jeju Island, South Korea. CKD was defined as estimated glomerular filtration rate &60 mL/min/1.73 m².@*RESULTS@#A total of 493 participants were included in the analysis, and 72 (14.6%) of them were identified as diagnosed with CKD. There was a statistical difference in the prevalence of CKD among the subjects with &6 hours (24.1%), 6 to 8 hours (8.4%) and ≥8 hours (18.2%) of daily average sleep duration (p&0.001). Multivariable analyses revealed that daily average sleep duration of <6 hours [odds ratio (OR)=3.79, p=0.007] and ≥8 hours (OR=3.39, p=0.009) were significantly associated with CKD compared to 6 to 8 hours of the duration.@*CONCLUSIONS@#Our findings suggest that both shorter and longer sleep duration give a higher risk of having CKD among the agriculture population. Adequate sleep within 6 to 8 hours a day can help prevent CKD in the agriculture population.
