ClinConnect Summary

This study is observational and cross-sectional, meaning researchers will observe and measure things as they coexist in real life, not test a new treatment. It aims to learn how much salt Spanish schoolchildren aged 7–11 eat and how this relates to body weight, blood pressure, and overall health. To estimate salt intake, they will use a urine test collected over 24 hours and three days of dietary records, along with simple health measurements like height, weight, and body fat. The goal is to determine average salt intake, identify main food sources of sodium, and provide data to support efforts to reduce salt in kids’ diets.

Eligible children are those aged 7–11 who attend school in Spain and can participate with parental consent. Exclusion rules include having certain metabolic or chronic illnesses, taking medicines that could affect blood pressure or sodium levels, or not being in school on measurement days. About 400 children from different regions are expected to join. Participants will provide a 24-hour urine sample, complete dietary records, and undergo basic measurements; the study does not involve a new drug or device, and results may help create reference data and inform public health campaigns to lower salt intake in children.
