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.
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.

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

|---|---|---|---|---|
| STHS Intervention | Behavioral | 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. |
| Measure | Description | Time Frame |
|---|---|---|
| Presence or absence of metabolic syndrome (MetS) | 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:
| Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
| Change in the number of MetS risk factors | Change in the number of MetS risk factors = (new # of MetS risk factors) - (original # of MetS risk factors) Measures to determine MetS risk factors:
| Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
| Positive Youth Development score | 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:
| Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
| Measure | Description | Time Frame |
|---|---|---|
| Blood pressure level | Blood pressure (systolic and diastolic) will be measured with two numbers using an automated Omron sphygmomanometer. | Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
| Concentration of blood glucose |

Glucose will be measured using a portable Cholestech LDX analyzer to assess a single capillary blood sample following an overnight fast. |
| Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
| Waist circumference | Waist circumference will be measured at the midpoint between the floating rib and iliac crest using a tape measure. | Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
| Concentration of HDL cholesterol | HDL-C will be measured using a portable Cholestech LDX analyzer to assess a single capillary blood sample following an overnight fast. | Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
| Concentration of serum triglycerides | Triglycerides will be measured using a portable Cholestech LDX analyzer to assess a single capillary blood sample following an overnight fast. | Baseline, 9 months (immediate post intervention), 4 months and 12 months post intervention |
