Abstract

PURPOSE
To investigate the incidence of nitrituria and the relationship between nitrituria and metabolic syndrome (MetS).
METHODS
Data from the Korean National Health and Nutrition Examination Survey V were used. A total of 19,083 participants were included. The chi-square test, the Mantel-Haenszel extension, logistic regression analysis, and multiple linear regression were used to analyze the data.
RESULTS
A total of 2.0% of the participants had nitrituria. The incidence of nitrituria significantly increased with age (P trend<0.001). In addition, nitrituria in women began to significantly increase in the fifth decade, more than in men, and this difference was maintained in the 60s, 70s, and greater than 70s age groups (P<0.001). After adjusting for confounders, the odds ratio (OR) for nitrituria in the MetS group was significantly increased, as compared to the OR for nitrituria in the group without MetS (MetS: OR, 1.577; 95% confidence interval [CI], 1.134-2.192; P=0.007). The glycosylated hemoglobin of the nitrite positive group was significantly higher than the negative group (adjusted mean ±standard error: 6.108 ±0.081 vs. 5.883±0.065, P<0.001).
CONCLUSIONS
An effective health policy for urinary tract infection (UTI) is needed for older age groups and women. Screening or management guidelines for UTI are needed in MetS patients.
