HSRC: Optimizing the Impact of the Healthy School Recognized Campus Program on Youth's CVD Risk Factors
Study Details
Study Description
Brief Summary
Healthy School Recognized Campus is a Texas A&M AgriLife Extension initiative that supports the delivery of school-based physical activity and nutrition programs for diverse youth across Texas. The purpose of this study is to improve the delivery of these programs and optimize the effect they have on youth's cardiovascular risk factors.

Detailed Description
The investigators will conduct a group randomized factorial trial using the Multiphase Optimization STrategy (MOST) framework to evaluate the impact (i.e., implementation and effectiveness) of three implementation strategies on program implementation and youth's cardiovascular disease risk. HSRC is a Texas A&M AgriLife Extension initiative that supports the delivery of school-based physical activity and nutrition programs.
Elementary schools in North and East Texas (n=16) of similar socio-economic status will be randomized at baseline to receive either 3, 2, 1, or no strategies to support HSRC program implementation. All schools will participate in HSRC during the full school year.
The investigators hypothesize that one strategy will result in significantly greater HSRC implementation and effectiveness than the other strategies tested.

Outcome Measures
Primary Outcome Measures
- Presence or absence of metabolic syndrome (MetS) [Baseline, 9 months (immediate 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: Abdominal obesity: waist circumference >90th percentile for child's sex and age High blood pressure: systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥90 mmHg) High blood glucose: blood glucose ≥5.6 mmol/L or known diabetes Low HDL cholesterol: HDL cholesterol <1.03 mmol/L High triglyceride level: Triglyceride level ≥ 1.7mmol/L
- Change in the number of MetS risk factors [Baseline, 9 months (immediate 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: Abdominal obesity: waist circumference >90th percentile for child's sex and age High blood pressure: systolic blood pressure ≥130 mm Hg or diastolic blood pressure ≥90 mmHg) High blood glucose: blood glucose ≥5.6 mmol/L or known diabetes Low HDL cholesterol: HDL cholesterol <1.03 mmol/L High triglyceride level: Triglyceride level ≥ 1.7mmol/L
- Number of programs schools delivered (in addition to Walk Across Texas) [Baseline, 9 months (immediate post intervention)]
- Number of sessions delivered for each program [Baseline, 9 months (immediate post intervention)]
- Length of the sessions delivered [Baseline, 9 months (immediate post intervention)]
- Individual-level attendance data for programs delivered [Baseline, 9 months (immediate post intervention)]
- Body mass index (BMI) [Baseline, 9 months (immediate post intervention)]
Weight will be measured with a scale (in pounds), and height will be measured using a stadiometer (in inches). Weight and height will be combined to report BMI as follows, BMI = (weight (lb)/height (inches)2) x 703.
- Concentration of subdermal carotenoids [Baseline, 9 months (immediate 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.
- Physical fitness capacity estimation [Baseline, 9 months (immediate post intervention)]
Physical fitness will be measured using the FitnessGram PACER multistage aerobic capacity test: Children will run back and forth 20 meters, with an initial running speed of 8.5 km/hour and a progressive 0.5-km/hour increase in running speed every minute. As the test continues it becomes progressively harder. The number of laps completed is used to estimate children's physical fitness physical fitness.
Secondary Outcome Measures
- Blood pressure level [Baseline, 9 months (immediate post intervention)]
Blood pressure (systolic and diastolic) will be measured with two numbers using an automated Omron sphygmomanometer.
- Concentration of blood glucose [Baseline, 9 months (immediate post intervention)]
Glucose will be measured using a portable CardioChek Plus analyzer to assess a single capillary blood sample following an overnight fast.
- Waist circumference [Baseline, 9 months (immediate post intervention)]
Waist circumference will be measured at the midpoint between the floating rib and iliac crest using a tape measure.
- Concentration of HDL cholesterol [Baseline, 9 months (immediate post intervention)]
HDL-C will be measured using a portable CardioChek Plus analyzer to assess a single capillary blood sample following an overnight fast.
- Concentration of serum triglycerides [Baseline, 9 months (immediate post intervention)]
Triglycerides will be measured using a portable CardioChek Plus analyzer to assess a single capillary blood sample following an overnight fast.
- Height [Baseline, 9 months (immediate post intervention)]
Height will be measured using a stadiometer in inches.
- Weight [Baseline, 9 months (immediate post intervention)]
Weight will be measured with a scale in pounds.
