- Brief Summary
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.
- Detailed Description
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.

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

- Primary Outcome Measures
Name Time Method Presence or absence of metabolic syndrome (MetS) Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention MetS is present after identifying abdominal obesity plus at least two of the four other MetS Risk factors: high blood pressure, high blood sugar, low HDL cholesterol, and high triglyceride levels.
MetS = (abdominal obesity) + (2 of 4 other MetS Risk factors)
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
4. Low HDL cholesterol: HDL cholesterol \<1.03 mmol/L
5. High triglyceride level: Triglyceride level ≥ 1.7mmol/LChange in the number of MetS risk factors Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention Change in the number of MetS risk factors = (new # of MetS risk factors) - (original # of MetS risk factors)
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
4. Low HDL cholesterol: HDL cholesterol \<1.03 mmol/L
5. High triglyceride level: Triglyceride level ≥ 1.7mmol/LPositive Youth Development score 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)
- Secondary Outcome Measures
Name Time Method Height Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention Height will be measured using a stadiometer in inches.
Concentration of HDL cholesterol Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention HDL-C will be measured using a portable Cholestech LDX analyzer to assess a single capillary blood sample following an overnight fast.
Concentration of serum triglycerides Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention Triglycerides will be measured using a portable Cholestech LDX analyzer to assess a single capillary blood sample following an overnight fast.
Blood pressure level Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention Blood pressure (systolic and diastolic) will be measured with two numbers using an automated Omron sphygmomanometer.
Accelerometer-derived physical activity estimation Baseline to 9 months Physical activity will be measured using Actigraph accelerometers. Measurements will include light physical activity (PA), moderate PA, moderate to vigorous PA, and vigorous PA.
Concentration of blood glucose Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention Glucose will be measured using a portable Cholestech LDX analyzer to assess a single capillary blood sample following an overnight fast.
Waist circumference Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention Waist circumference will be measured at the midpoint between the floating rib and iliac crest using a tape measure.
Assessment of perceptions of school environments and school-specific dietary intake patterns Baseline to 9 months Perceptions related to physical activity and nutrition within the school setting will be measured using the Perceptions of the Environment and Patterns of Diet at School (PEA-PODS) survey.
Assessment of participatory competence and decision-making Baseline to 9 months Participatory competence and decision-making will be measured using the Youth Engagement and Action for Health (YEAH!) survey. The YEAH survey will be used to assess students' participatory competence and decision-making (i.e., ability to influence group decision-making).
Peer concentration of subdermal carotenoids Baseline to 9 months The concentration of subdermal carotenoids will assess peers' engagement in health behaviors changes in fruit and vegetable consumption using the Veggie Meter: A non-invasive, portable machine that measures subdermal carotenoid levels using resonance Raman spectroscopy.
Weight Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention Weight will be measured with a scale in pounds.
Concentration of subdermal carotenoids Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention The concentration of subdermal carotenoids will assess the changes in fruit and vegetable consumption using the Veggie Meter: A non-invasive, portable machine that measures subdermal carotenoid levels using resonance Raman spectroscopy.
