Official title

Sodium Sources and Sodium Intake in a Representative Sample of Spanish Children and Its Effects on Body Weight and Blood Pressure

Overview

Previous evidence shows that sodium intake in Spanish adult population is over the recommended limits and this high sodium intake is related with difficulties in body weight control and blood pressure control. The aim of this study is to stablish a direct relationship between salt intake and the health parameters previously mentioned in a representative sample of Spanish schoolchildren between 7-11 years old. The investigators are applying a 3-day dietary records to collect dietary data, and collecting 24-h urine samples in order to analyse biochemical indicators of sodium intake and other nutrients. Anthropometric data are also being recorded and body composition is also analysed using bioimpedance technique.

Detailed description

Specific Aims

1. To stablish the average sodium intake in Spanish children, using a 24-h urine sample and validated dietary questionnaires. 2. To compare 24-hour urinary sodium measurement to the dietary survey method 3. To study the relationship between sodium intake and blood pressure levels in Spanish scholars. 4. To analyze the relationship between sodium intake and overweight/obesity in Spanish children using anthropometric and bioimpedance analysis measures. 5. To identify main food sources of sodium in the diet of Spanish schoolchildren and the use of discretionary salt. 6. Provide new data for monitoring sodium intake in Spanish schoolchildren and design campaigns to reduce their intake. 7. To provide reference data of sodium intake on a representative sample of the Spanish child population for European and international databases.

Primary outcome measures

  • 24-h urinary sodium excretion in Spanish schoolchildren [Time frame: Through study completion, an average of 2 years]
Secondary outcome measures (1)
  • Common sodium food sources [Time frame: Through study completion, an average of 2 years]

Eligibility criteria

Inclusion criteria

  • Age between 7 and 11 years old

Exclusion criteria

  • Those who have any clinical problem, which may modify the results of the analysis: metabolic or chronic diseases (liver, kidney, diabetes, hypothesis or hyperkalemia), pharmacological treatment during the 3 months prior to the study with corticosteroids, insulin, diuretics or other drugs that may modify blood pressure figures, surgery or serious infectious diseases in the previous 6 months.
  • Those who were not in the school when the measures were taken.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
