Health Promotion Workshop in Primary School Children (HEALTH-KIDS)

March 20, 2026 updated by: Maria Blanco Diaz, University of Oviedo

Impact of a Health Promotion Workshop on Knowledge of Healthy Habits and Postural Hygiene in 3rd Grade Primary School Children

This study evaluates whether a brief educational workshop can improve knowledge of healthy habits and postural hygiene in primary school children.

The study will be conducted in 3rd grade students (8-9 years old) from a primary school in Spain. Children in the intervention group will attend a 45-minute health promotion workshop covering physical activity, correct posture in daily activities, backpack organization and basic musculoskeletal self-care. Children in the control group will not receive the workshop during the initial phase.

All participating students will complete a short knowledge questionnaire before and after the workshop period. The study aims to determine whether children who receive the workshop show greater improvement in knowledge compared to those who do not.

Participation is voluntary and requires written informed consent from parents or legal guardians. No medical procedures, treatments, access to medical records or biological samples are involved. Data will be coded and treated confidentially.

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

This is a quasi-experimental study with two parallel groups designed to assess the effectiveness of a health promotion educational intervention in primary school children.

Participants will be students enrolled in the 3rd grade of a primary school in Spain. Inclusion requires written informed consent from parents or legal guardians. Students will be assigned to either an intervention group or a control group based on natural classroom organization to avoid cross-contamination between groups.

The intervention consists of a single 45-minute educational workshop delivered during school hours. The workshop content includes promotion of physical activity, principles of postural hygiene in sitting and standing, correct backpack use, active breaks during study time, and basic concepts of musculoskeletal self-care. Standardized educational materials and audiovisual resources adapted to the children's age will be used to ensure consistency.

A knowledge questionnaire composed of multiple-choice items will be administered to both groups before the intervention and again after the intervention period. The repetition of the questionnaire in the control group allows control of the potential learning effect associated with test repetition, enabling attribution of observed changes to the educational intervention.

The primary outcome measure is the change in knowledge score between pre- and post-intervention assessments. Secondary outcomes include participant satisfaction with the workshop.

The study does not involve clinical or medical procedures, administration of treatments, access to medical records or collection of biological samples. Participation is voluntary, and confidentiality will be guaranteed by coding all data and restricting access to authorized investigators only.

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

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
Change in Health Knowledge Score (Ad Hoc Knowledge Questionnaire on Healthy Habits and Postural Hygiene)
Time Frame: Baseline and immediately after the educational intervention (within 1-3 days).

Difference in the total score obtained in an ad hoc knowledge questionnaire on healthy habits and postural hygiene between pre-intervention and post-intervention assessments.

The questionnaire consists of 10 multiple-choice questions with a single correct answer. Each correct answer scores 1 point, resulting in a total score ranging from 0 to 10. Higher scores indicate a higher level of knowledge.
Baseline and immediately after the educational intervention (within 1-3 days).
