Health Promotion Workshop in Primary School Children

Overview

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.

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.
