Consistency between 3 days' dietary records and 24-h urine in estimating salt intake in children and adolescents.

ABSTRACT:

Purpose

This study aimed to evaluate the salt intake in boarding school students and the consistency between salt intake measurements based on 24-h urine and weighed dietary records over 3 consecutive days in this population.

Methods

This was a school-based cross-sectional study. Overweight (including obesity) or hypertensive students aged 6-14 years and their normal counterparts were recruited for this study at three boarding schools in China. Three consecutive 24-h urine samples were collected from all participants. During the collection period of 24-h urine, the weighed diet records were collected in children who had all three meals at the school canteens on weekdays. Incomplete 24-h urine or dietary records were excluded from the analysis.
