Automated Ecological Assessment Of Physical Activity: Advancing Direct Observation., Jordan A. Carlson, Bo Liu, James F. Sallis, Jacqueline Kerr, J Aaron Hipp, Vincent S. Staggs, Amy Papa, Kelsey Dean, Nuno M. Vasconcelos

Manuscripts, Articles, Book Chapters and Other Papers

Technological advances provide opportunities for automating direct observations of physical activity, which allow for continuous monitoring and feedback. This pilot study evaluated the initial validity of computer vision algorithms for ecological assessment of physical activity. The sample comprised 6630 seconds per camera (three cameras in total) of video capturing up to nine participants engaged in sitting, standing, walking, and jogging in an open outdoor space while wearing accelerometers. Computer vision algorithms were developed to assess the number and proportion of people in sedentary, light, moderate, and vigorous activity, and group-based metabolic equivalents of tasks (MET)-minutes. Means and standard deviations (SD) …

A Nationwide Study On The Prevalence Of Functional Gastrointestinal Disorders In School-Children., Miguel Saps, Jairo Enrique Moreno-Gomez, Carmen Rossy Ramírez-Hernández, John M. Rosen, C A. Velasco-Benitez

Manuscripts, Articles, Book Chapters and Other Papers

Introduction: Functional gastrointestinal disorders (FGIDs) are highly prevalent worldwide and are thought to result from the interplay of multiple factors that can vary from region to region. Nationwide studies can help understand the regional epidemiology and the pathogenesis of FGIDs. The objectives of this study were to determine the prevalence of FGIDs in school-children of Colombia and assess associated factors.

Methods: A cross-sectional study was carried out at twelve private and public schools in ten cities distributed through the four main geographic regions of Colombia. School-children completed a validated questionnaire to assess functional gastrointestinal disorders according to Rome III criteria. …

Within-Person Associations Of Young Adolescents' Physical Activity Across Five Primary Locations: Is There Evidence Of Cross-Location Compensation?, Jordan A. Carlson, Tarrah B. Mitchell, Brian E.

BACKGROUND: Youth are active in multiple locations, but it is unknown whether more physical activity in one location is associated with less in other locations. This cross-sectional study examines whether on days with more physical activity in a given location, relative to their typical activity in that location, youth had less activity in other locations (i.e., within-person associations/compensation).

METHODS: Participants were 528 adolescents, ages 12 to 16 (M = 14.12, SD = 1.44, 50% boys, 70% White non-Hispanic). Accelerometer and Global Positioning System devices were used to measure the proportion of time spent in moderate-to-vigorous physical activity (MVPA) in five …

Tobacco Product Use Among Lesbian, Gay, And Bisexual Adolescents., Hongying Dai

Manuscripts, Articles, Book Chapters and Other Papers

OBJECTIVES: Sexual minority youth face health disparities and a high risk of substance abuse. This study sought to fully characterize the disparity of tobacco use and risk factors in this high-risk subpopulation.

METHODS: Using data from the 2015 Youth Risk Behavior Survey, the current use of various tobacco products (cigarettes, smokeless tobacco, cigars, and e-cigarettes) was compared according to sex and distinct sexual identities (lesbian, gay, bisexual, and unsure). Heterosexual/straight adolescents served as the control group.

RESULTS: Of 14 703 respondents, 88.8% were heterosexual/straight, 2.0% were lesbian or gay, 6.0% were bisexual, and 3.2% were unsure about their sexual identity. …

Expectations For Treatment In Pediatric Weight Management And Relationship To Attrition., Erinn T. Rhodes, Richard E. Boles, Kimberly Chin, Amy Christison, Elizabeth Getzoff Testa, Kimberly Guion, Mary Jane Hawkins, Carter R. Petty, Bethany Sallinen Gaffka, Melissa Santos, Laura Shaffer, Jared Tucker, Sarah Hampl

BACKGROUND: Attrition in pediatric weight management negatively impacts treatment outcomes. A potentially modifiable contributor to attrition is unmet family expectations. This study aimed to evaluate the association between adolescent and parent/guardian treatment expectations and attrition.

PATIENTS AND METHODS: A prospective, nonrandomized, uncontrolled, single-arm pilot trial was conducted among 12 pediatric weight management programs in the Children's Hospital Association's FOCUS on a Fitter Future collaborative. Parents/guardians and adolescents completed an expectations/goals survey at their initial visit, with categories including healthier food/drinks, physical activity/exercise, family support/behavior, and weight management goals. Attrition was assessed at 3 months.

RESULTS: From January to August 2013, …

Evaluating The Accountable Health Communities Demonstration Project., Laura Gottlieb, Jeffrey D. Colvin, Eric Fleegler, Danielle Hessler, Arvin Garg, Nancy Adler

Manuscripts, Articles, Book Chapters and Other Papers

Despite substantial evidence documenting the social patterning of disease, relatively little information is available on how the health care system can best intervene on social determinants to impact individual and population health. Announced in January 2016, the Centers for Medicare and Medicaid Innovation's (CMMI) Accountable Health Communities (AHC) initiative provides an important opportunity to improve the evidence base around integrated social and medical care delivery. To maximize learning from this large-scale demonstration, comprehensive evaluation efforts should focus on effectiveness and implementation research by supporting local, regional, and national studies across a range of outcomes. Findings from this demonstration could transform …

Predictors Of Loss To Follow-Up Among Children With Type 2 Diabetes., Ashley Shoemaker, Peiyao Cheng, Robin L. Gal, Craig Kollman, William V. Tamborlane, Georgeanna J. Klingensmith, Mark A. Clements, Tamara S. Hannon, Rubina Heptulla, Joane Less, Jamie Wood, Pediatric Diabetes Consortium

BACKGROUND/AIMS: Youth with type 2 diabetes (T2D) have poor compliance with medical care. This study aimed to determine which demographic and clinical factors differ between youth with T2D who receive care in a pediatric diabetes center versus youth lost to follow-up for >18 months.

METHODS: Data were analyzed from 496 subjects in the Pe-diatric Diabetes Consortium registry. Enrollment variables were selected a priori and analyzed with univariable and multivariable logistic regression models.

RESULTS: After a median of 1.3 years from enrollment, 55% of patients were lost to follow-up. The final model included age, race/ethnicity, parent education, and estimated distance to …

Should School Boards Discontinue Support For High School Football?, Lewis H. Margolis, Greg Canty, Mark Halstead, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

A pediatrician is asked by her local school board to help them decide whether to discontinue their high school football program. She reviews the available evidence on the risks of football and finds it hopelessly contradictory. Some scholars claim that football is clearly more dangerous than other sports. Others suggest that the risks of football are comparable to other sports, such as lacrosse, ice hockey, or soccer. She finds very little data on the long-term sequelae of concussions. She sees claims that good coaching and a school culture that prioritizes the health of athletes over winning can reduce morbidity from …
