Starke Teenager für gesunde Schulen Change Club: Ein Ansatz des bürgerschaftlichen Engagements zur Verbesserung körperlicher Aktivität und einer Umgebung für gesunde Ernährung

29. September 2026 aktualisiert von: Texas A&M University

Strong Teens for Healthy Schools (STHS) is a school-based, civic engagement program that empowers middle school students to improve their physical activity and healthy eating behaviors, improve their cardiovascular disease outcomes, and create positive change in their school health environments.

Detaillierte Beschreibung

The investigators will conduct a cluster-randomized controlled trial to evaluate the impact of the Strong Teens for Healthy Schools (STHS) program on cardiovascular disease-related outcomes. STHS is a multi-level, theory-based civic engagement program to catalyze positive food and physical activity environmental change and improve cardiovascular disease-related health (CVD) outcomes among 6th and 7th-grade students.

Title 1 middle schools in Texas (n=20) with > 40% Hispanic and Black students will be randomized at baseline to the intervention condition (STHS program) or control condition (will continue with usual care, as they will not be asked to add or remove any of their current, physical activity, healthy eating, or positive youth development programming) (n=20-25 students per school).

The investigators hypothesize that students who participate in STHS will have reduced MetS risk, improved positive youth developmental outcomes, and improved social and environmental outcomes immediately post-intervention and one year after study completion compared to students in a control condition.

Waffen und Interventionen

Teilnehmergruppe / Arm
Intervention / Behandlung
Experimental: STHS Intervention

Participants in this group (10 schools) will participate in the STHS program.

STHS program

The intervention group (10 schools) will participate in the STHS program. During the fall semester (September to December), the intervention group will receive 24 thirty-minute modules (or twelve 1-hour modules) that provide education on civic engagement, healthy eating, and physical activity. During the spring semester (February to May), the intervention group will receive 24 thirty-minute modules (or twelve 1-hour modules) that focus on implementing the school health environmental change project and receive support for maintaining individual-level healthy eating and physical activity behaviors.

Sonstiges: Usual Care

Participants in this group (10 schools) will continue with usual care, as they will not be asked to add or remove any of their current, physical activity, healthy eating, or positive youth development programming.

No STHS program

The usual care group will be offered the same activities as the intervention group after the conclusion of the research study.

Zeitfenster
Presence or absence of metabolic syndrome (MetS)

Measures to determine MetS risk factors:

  1. Abdominal obesity: waist circumference >90th percentile for child's sex and age
  2. High blood pressure: systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥90 mmHg)
  3. High blood glucose: blood glucose ≥5.6 mmol/L or known diabetes

Change in the number of MetS risk factors
Zeitfenster: Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention

Measures to determine MetS risk factors:

  1. Abdominal obesity: waist circumference >90th percentile for child's sex and age
  2. High blood pressure: systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥90 mmHg)
  3. High blood glucose: blood glucose ≥5.6 mmol/L or known diabetes

Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention
Positive Youth Development score
Zeitfenster: Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention

Positive youth development will be measured using a 5 C's Model of Positive Youth Development Scale-Short Form (PYD-SF): A 34-item scale that assesses the strength of psychological, behavioral, and social development in youth.

The five dimensions measured are:

  1. Competence (sense of proficiency)
  2. Confidence (self-worth, self-efficacy)
  3. Character (adherence to societal and cultural rules)
  4. Connection (bonds with people and institutions)
  5. Caring (sympathy and empathy towards others)
