Abstract

BACKGROUND
Several studies have found an association between decreased respiratory function and renal impairment in those with chronic kidney disease. The relationship has not been investigated for healthy smokers. The aim of this study was to examine the association between respiratory function and renal function according to smoking status in Korean male population.
METHODS
From the 5th Korean National Health and Nutrition Examination Survey (KNHANES), we enrolled 1246 male participants who were 40 years or older. As a cross-sectional study, the association between respiratory function and renal function were analysed depending on the' smoking status. Pearson correlation analysis was used to find the association between respiratory function and renal impairment. Covariance Analysis allowed to compare renal function (albuminuria, eGFR) with respiratory function (FEV1, FVC) according to smoking status.
RESULTS
Regardless of smoking status, there was a negative correlation between respiratory function (FEV1 and FVC) and urinary albumin to creatinine ratio (LogUACR), and positive correlation between respiratory function (FEV1 and FVC) and estimated glomerular filtration rate (eGFR). Smokers have lower FEV1 and FVC in case they have albuminuria, after adjusting for covariant (P=0.012, P=0.010, respectively).
CONCLUSIONS
Respiratory function was significantly lower in male smokers with albuminuria. Primary care physicians need to recognize that albuminuria may accompany with decreased respiratory function and to detect renal function impairment earlier in male smokers.
