Sodium intake and kidney function in the general population: an observational, population-based study.

ABSTRACT:

Background

The relationships of sodium intake to kidney function within the population have been poorly investigated and are the objective of the study.

Methods

This observational, population-based, cross-sectional and longitudinal study targeted 4595 adult participants of the Gubbio study with complete data at baseline exam. Of these participants, 3016 participated in the 15-year follow-up (mortality-corrected response rate 78.4%). Baseline measures included sodium:creatinine ratio in timed overnight urine collection, used as an index of sodium intake, together with serum creatinine, sex, age and other variables. Follow-up measures included serum creatinine and other variables. Estimated glomerular filtration rate (eGFR, mL/min/1.73 m²) was calculated using serum
