Health Literacy and Overweight in Adolescents

Completed

• Conditions: Overweight and Obesity

• Registration Number: NCT03482193
• Lead Sponsor: University of Liege

Brief Summary

Obesity in children and adolescents has become a major public health problem in recent years. In Belgium, 20% of people aged between 2 and 17 are overweight and 7% suffer from obesity. While studies often associate this overweight with socio-economic level, other factors, such as health literacy (HL), may also play a role. Among adolescents, some studies have shown an association between the level of HL and the Body Mass Index (BMI). Our study aims to investigate the association between HL of adolescents and their BMI.

This is a cross-sectional survey among 9 high schools in a medium city of Belgium, including 254 high school students aged between 12-17 years. Health literacy was assessed by the Health Literacy Measure for Adolescents (HELMA). Student's age, sex, weight, size and parental socio-economic status are gathered in the medical file during the medical examination organized by the schools after obtaining the informed consent of the students and their parents.

Health Literacy	1 day (At the inclusion in the study)	The degree to which individuals can obtain, process and understand basic health information and services needed to make appropriate health decisions.
