Optimizing the Impact of the Healthy School Recognized Campus Program on Youth's CVD Risk Factors

Presence or absence of metabolic syndrome (MetS)

时间窗: 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: 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/L

Number of sessions delivered for each program

时间窗: Baseline, 9 months (immediate post intervention)

Length of the sessions delivered

时间窗: Baseline, 9 months (immediate post intervention)

Individual-level attendance data for programs delivered

时间窗: Baseline, 9 months (immediate post intervention)

Concentration of subdermal carotenoids

时间窗: 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.

Change in the number of MetS risk factors

时间窗: 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: 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/L

Body mass index (BMI)

时间窗: 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.

Number of programs schools delivered (in addition to Walk Across Texas)

时间窗: Baseline, 9 months (immediate post intervention)

Physical fitness capacity estimation

时间窗: 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.
