School Policy, Food And Physical Activity Environment, And Childhood Obesity, Ruicui Liu
School Policy, Food And Physical Activity Environment, And Childhood Obesity, Ruicui Liu
Health Services Research Dissertations
The purpose of this study is to examine the effect of school food and physical activity environments on energy balance-related behaviors and Body Mass Index (BMI) and to simulate the effect of school-based nutrition and physical activity policies on childhood obesity prevention. Four models based on the Social Ecological Framework of childhood obesity were developed. Parameters of these models were calibrated and validated with empirical data derived from the Early Childhood Longitudinal Study – Kindergarten Class of 1998-99 and the 2003-2004 National Health and Nutrition Examination Study. The correlation between observed and simulated BMI was 0.85 for 5th grade children …
Icook 4-H: 0 To 24-Month Accelerometer-Derived Physical Activity And Sedentary Time In Youth, Emily Hofer
Icook 4-H: 0 To 24-Month Accelerometer-Derived Physical Activity And Sedentary Time In Youth, Emily Hofer
Electronic Theses and Dissertations
To assess accelerometer-derived physical activity and sedentary time from 0 to 24- months in youth in the iCook 4-H program. The iCook 4-H Program was a 5-state, randomized, control-treatment, family-based childhood obesity prevention intervention promoting cooking, eating and playing together. Youth, 9-10 years old, and their main adult meal preparer, participated in the 12-week program followed by monthly newsletters and bi-yearly booster sessions until 24-months. Physical activity and sedentary time were determined for youth who wore an Actigraph GT3X+ accelerometer for 7 days at 0, 4, 12, and 24-months and met defined accelerometer compliance standards. Mean daily minutes of sedentary …
The Feasibility And Validity Of Novel Dietary Assessment Methods In A Pre-School Setting, Harley Eriksen
The Feasibility And Validity Of Novel Dietary Assessment Methods In A Pre-School Setting, Harley Eriksen
Graduate College Dissertations and Theses
To properly evaluate initiatives targeting children's fruit and vegetable (FV) consumption, we need feasible and valid dietary assessment methods that are time, cost, and resource effective. The objectives of this study were to test the feasibility and validity of two methods, digital imaging (DI) and aggregate plate waste (APW), for assessing children's FV consumption. UVM dietary assessment team graduate students prepared and distributed FV snacks in two pre-school classrooms over 30 consecutive school days. Feasibility of APW was tested by recording the frequency and weight of waste sorting errors by pre-school children and performing paired t-tests comparing uncorrected and corrected …
