Efficacy of an Educational School-based Intervention to Reduce Prevalence of Obesity in Childhood-EdAl-2 (EDAL2)

September 28, 2021 updated by: Rosa Sola, University Rovira i Virgili

A Primary-school-based Study to Reduce Prevalence of Childhood Obesity in Terres de l'Ebre (Catalunya (Spain) - EDAL-Educació en Estils Saludables de Vida alimentació-2: Study Protocol for a Randomized Controlled Trial

Our hypothesis is that a regular systematic educational intervention in primary school improves lifestyle choices and reduces obesity. As such, the aim of the study is to evaluate the effects of a 3-year school-based program of lifestyle improvement, including diet and physical activity, implemented by university students acting as "health promoting agents" (HPA) on the prevalence of obesity.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Initial pupil enrollment and continued for 3 years.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

7 years to 8 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • In the intervention group, all children of the selected classroom are exposed to the intervention.
  • The data a will collected on all the children, but only the data from individuals (and their parents) who provided informed consent are included in the final analyses.
  • Name, gender, date and place of birth are recorded at the start of the program, while weight, height, body mass index (BMI) and waist circumference variables (identified set of anthropometric measures) are recorded in each of the 3 academic years of the study.

Exclusion Criteria:

  • No adequate age
  • Lack of inclusion criteria

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
No Intervention: control
Control pupils follow their usual activities
Experimental: lifestyle counseling

In 3 academic years, the intervention program consisted of three components:

  1. Classroom practice by HPA to highlight healthy lifestyle habits
  2. Teaching practice by HPA using books designed to include the nutritional objectives
  3. Parental activities included with their children

In each of 12 activities (1 h/activity), the classroom practice consisted of three components:

  1. Experimental development of activities regarding each healthy lifestyle habit
  2. Assessment of activity performed in classroom
  3. An activity developed for use at home
Behavioral: lifestyle counseling

In 3 academic years, the intervention program consisted of three components:

  1. Classroom practice by HPA to highlight healthy lifestyle habits
  2. Teaching practice by HPA using books designed to include the nutritional objectives
  3. Parental activities included with their children

  • Childhood obesity

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
Reduction in prevalence of obesity
Time Frame: Changes from baseline in prevalence of obesity at 3 academic years
Primary outcomes include obesity (BMI ≥95th percentile) and overweight (BMI ≥85th percentile) We will analyzed obesity and overweight and a measure of thinness according to the Cole criteria as well as other measures of adiposity such as BMI z score and waist circumference. The numbers of subjects having a particular dietary habit are expressed as percentages of the total number of individuals being evaluated
Changes from baseline in prevalence of obesity at 3 academic years

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.
