简要总结
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.
详细描述
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.

结局指标
主要结局
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.
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 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.
Number of sessions delivered for each program
