About this study

Social-HEROES (Social Health and Education Research Opportunities: Empower Students and tackle inequities) is a cluster-randomised study that aims to improve the health of vulnerable preschool children (3 to 6 years old) attending Portuguese TEIP* schools.

Ten preschools (about 478 children) will be randomly assigned to one of two groups. Five preschools (≈ 239 children) will continue with their usual educational activities (control group). The other five preschools (≈ 239 children) will take part in a six-month "Social-HEROES" programme (intervention group).

The intervention is created in participatory innovation labs where children, educators, families, community members and policy-makers design activities together, guided by a systems-thinking approach. These activities encourage healthier eating, more balanced 24-hour movement (active play, less sitting, better sleep) and stronger socio-emotional skills.

The study pursues two main goals. First, it will develop this innovative, stakeholder-driven health-promotion programme. Second, it will test how well the programme works by measuring: (a) children's health-literacy levels, (b) their lifestyle habits (diet, physical activity, sedentary time and sleep), (c) rates of overweight and obesity, and (d) blood-pressure levels.

Researchers expect that, compared with the control group, children in the intervention group will show higher health-literacy scores, healthier lifestyle patterns and lower rates of excess weight and raised blood pressure. Data will be collected before the programme starts and again six months later, using short questionnaires, simple body measurements, blood-pressure readings and a wrist-worn activity tracker (accelerometer) worn for seven days. Participation is voluntary, can be stopped at any time without penalty, and all information is handled in accordance with GDPR.

Social-HEROES is funded by Fundación "la Caixa" (LCF/PR/SR24/57010020) and has ethical approval from the Life and Health Sciences Research Ethics Committee (CEICVS 189/2024). It addresses two pressing challenges at once: reducing early non-communicable-disease risks and narrowing social and educational health gaps among young children.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Social-HEROES Health-Promotion ProgramBehavioural

    Six-month, cluster-level, stakeholder-co-created health-promotion programme delivered in preschool settings. The programme is developed through participatory innovation labs and includes:

    • Educator training sessions (monthly)
    • Classroom activities on healthy eating, active play and socio-emotional skills (weekly)
    • Family workshops and take-home materials promoting 24-hour movement behaviour (diet, physical activity, reduced sedentary time, adequate sleep) (every 4-6 weeks)
    • Community engagement events (beginning and end of intervention). Implementation period: 6 months; dosage approx. 20-24 contact hours per child.

Usual Education ControlNo interventionPreschools (n = 5; ~ 239 children) continue their usual curriculum and health-education practices; no additional components are delivered. No intervention will occur.
Social-HEROES InterventionExperimentalSix-month, cluster-level programme co-created in participatory innovation labs. Includes classroom activities and family workshops to improve diet, 24-h movement (physical activity, sedentary time, sleep) and socio-emotional skills. Implemented in 5 preschools (~ 239 children).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Overweight and obesity

    Weight (kg) and height (m) will be measured by trained staff and used to calculate body mass index (BMI = kg/m²). Values will be converted into BMI-for-age z-scores using the WHO 2006 growth standards.

    Measured: 6 months

  2. Risk of high blood pressure

    Blood pressure percentile - Systolic and diastolic blood pressure will be measured using a validated paediatric oscillometric device. Percentiles adjusted for age, sex and height will be calculated according to AAP 2017 guidelines.

    Measured: 6 months

  3. Health literacy

    Assessed using the Health Literacy Survey for Children (HLS-Child), a 20-item scale scored from 1 (very difficult) to 4 (very easy). Total score range: 20 to 80. Higher scores indicate better health literacy.

    Measured: 6 months

Secondary outcomes (6)
  1. Dietary intake - fruit and vegetables

    Mean daily servings of fruits and vegetables will be estimated through a parent-completed 24-hour dietary recall. Unit: servings/day.

    Measured: 6 months

  2. Dietary intake - sugar-sweetened beverages

    Daily consumption of sugar-sweetened beverages will be estimated through a parent-completed 24-hour dietary recall. Unit: millilitres/day.

    Measured: 6 months

  3. Physical activity

    Moderate-to-vigorous physical activity (MVPA) Assessed using wrist-worn ActiGraph GT3X+ accelerometers over 7 consecutive days. Activity counts per minute will be processed using validated cut-points to calculate average daily MVPA. Unit: minutes/day.

    Measured: 6 months

  4. Sedentary time

    Accelerometer data from the same 7-day period will be analysed to estimate sedentary behaviour, defined as <100 counts per minute. Unit: minutes/day.

    Measured: 6 months

  5. Sleep duration

    Nightly sleep duration will be estimated using the Sadeh algorithm applied to 7-day ActiGraph GT3X+ wrist accelerometer data. Unit: hours/night.

    Measured: 6 months

  6. Sleep quality

    Assessed using the Portuguese version of the Children's Sleep Habits Questionnaire (CSHQ-PT), which includes 33 items scored from 1 (rarely) to 3 (usually). Total score range: 33 to 99. Higher scores indicate poorer sleep quality.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing Social-HEROES Health-Promotion Program in people with Overweight and Obesity, run by University of Minho at 1 site in Portugal.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: enrolling by invitation, as of the sponsor's last update on 28 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Portugal. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Overweight and obesity (time frame: 6 months). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2025.
