Health Literacy and Overweight in Adolescents

March 29, 2018 updated by: Isabelle Bragard, University of Liege

The Association of Adolescents' Interactive and Critical Health Literacy With Their Overweight: a Study in a Medium Urban City in Belgium

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.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Adolescents studying in 2nd or 4th year in one of the participating secondary school. Students in those years receive a medical examination, which facilitate the collect of data and made us chose to limit the participation to these 2 years.

Description

Inclusion Criteria:

  • Studying in one of the participating school
  • Being in 2nd or 4th year
  • Parental consent to participate

Exclusion Criteria:

  • None

Adolescents
Adolescents in 2nd or 4th year in secondary school, from 9 different schools in Liège, Belgium.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Health Literacy
Time Frame: 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. It also includes the cognitive and social skills which determine the motivation and ability of individuals to gain access to, understand and use information in ways which promote and maintain good health. It is measured by the Health Literacy Measure for Adolescents (HELMA) (Ghanbari et al., 2016), which is composed of 44 items. Health literacy was categorized into 4 categories based on the score to the questionnaire: excellent, sufficient, problematic and inadequate.
1 day (At the inclusion in the study)
Body Mass Index
Time Frame: 1 day (At the inclusion in the study)
Calculated with the standard formula (weight/height²) and categorized into 4 categories (underweight, normal, overweight, obesity) according to the PNNS and IOTF-25 and -30 curves.
1 day (At the inclusion in the study)
Parents' socio-economic status
Time Frame: 1 day (At the inclusion in the study)
We collected the profession of the parents' through the adolescent's medical file, and categorized them into 4 categories: worker, employee, independent, unemployed.
1 day (At the inclusion in the study)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

Time Frame: 1 day (At the inclusion in the study)
Collected through a socio-demographic questionnaire
1 day (At the inclusion in the study)
Education type
Time Frame: 1 day (At the inclusion in the study)

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2017

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
