Association between Dietary Intakes of Nitrate and Nitrite and the Risk of Hypertension and Chronic Kidney Disease: Tehran Lipid and Glucose Study.

ABSTRACT: The association of habitual intakes of dietary nitrate (NO₃-) and nitrite (NO₂-) with blood pressure and renal function is not clear. Here, we investigated a potential effect of dietary NO₃- and NO₂- on the occurrence of hypertension (HTN) and chronic kidney disease (CKD). A total of 2799 Iranian adults aged ≥20 years, participating in the Tehran Lipid and Glucose Study (TLGS), were included and followed for a median of 5.8 years. Dietary intakes of NO₃- and NO₂- were estimated using a semi-quantitative food frequency questionnaire. Demographics, anthropometrics, blood pressure and biochemical variables were evaluated at baseline and during follow-up examinations. To identify the odds ratio (OR) and 95% confidence interval (CI) of HTN and CKD across tertile categories of residual energy-ad
