The Association Between The Food Environment And Weight Status Among Eastern North Carolina Youth, Stephanie B. Jilcott, Scott Wade, Jared T. Mcguirt, Qiang Wu, Suzanne Lazorick, Justin B. Moore

Faculty Publications

Objective: To examine associations between various measures of the food environment and BMI percentile among youth.

Design: Cross-sectional, observational.

Setting: Pitt County, eastern North Carolina.

Subjects:We extracted the electronic medical records for youth receiving well child check-ups from January 2007 to June 2008. We obtained addresses for food venues from two secondary sources and ground-truthing. A geographic information systems database was constructed by geocoding home addresses of 744 youth and food venues. We quantified participants' accessibility to food venues by calculating 'coverage', number of food venues in buffers of 0●25, 0●5, 1 and 5 miles (0●4, 0●8, 1●6 and …

Equating Accelerometer Estimates Of Moderate-To-Vigorous Physical Activity: In Search Of The Rosetta Stone, Daniel B. Bornstein, Michael W. Beets, Wonwoo Byun, Gregory J. Welk, Matteo Bottai, Marsha Dowda, Russell R. Pate

Faculty Publications

Purpose - No universally accepted ActiGraph accelerometer cutpoints for quantifying moderate-to-vigorous physical activity (MVPA) exist. Estimates of MVPA from one set of cutpoints cannot be directly compared to MVPA estimates using different cutpoints, even when the same outcome units are reported (MVPA min•d^-1). The purpose of this study was to illustrate the utility of an equating system that translates reported MVPA estimates from one set of cutpoints into another, to better inform public health policy.

Design - Secondary data analysis.

Methods - ActiGraph data from a large preschool project (N=419, 3-6yr-olds, CHAMPS) was used to conduct the analyses. …

Physical Activity And Sedentary Activity Patterns Among Children And Adolescents: A Latent Class Analysis Approach, Carrie D. Patnode, Leslie A. Lytle, Darin J. Erickson, John R. Sirard, Daheia J. Barr-Anderson, Mary Story

Faculty Publications

Background: While much is known about the overall levels of physical activity and sedentary activity among youth, few studies have attempted to define clusters of such behaviors. The purpose of this study was to identify and describe unique classes of youth based on their perception in a variety of physical activity and sedentary behaviors. Methods: Latent class analysis was used to characterize segments of youth based on patterns of self-reported and accelerometer-measured participation in 12 behaviors. Children and adolescents (N =720) from 6th-11th grade were included in the analysis. Differences in class membership were examined using multinomial logistic …
