Objective: To quantitatively characterize change in health-related quality of life (HRQoL) in the context of behavioral (n = 16), surgical (n = 5), and pharmacological (n = 1) interventions for pediatric overweight and obesity. A secondary goal was to examine the relationship between change in HRQoL and change in body mass index (ΔBMI) by treatment type. The amount of weight loss necessary to observe a minimally clinically important difference (MCID) in HRQoL was determined.

The proportion of obese adolescents in Southern Appalachia is among the highest in the nation. Through funding from the National Institute on Minority Health and Health Disparities--National Institutes of Health, the Team Up for Healthy Living project was a cluster-randomized trial targeting obesity prevention in adolescents through a cross-peer intervention. The specific aims of the project were to: 1) develop a peer-based health education program focusing on establishing positive peer norms towards healthy eating and physical activity (PA) among high school students, 2) test program efficacy, and 3) explore mechanisms underlying the program.

This study examined health-related quality of life (HRQoL) across weight categories in adolescents using both a general and a condition-specific measure sensitive to fatigue symptoms. Participants (N = 918) completed the Pediatric Quality of Life (PedsQL) Inventory and PedsQL Multidimensional Fatigue Scale measures. Actual height and weight were used to calculate body mass index for age and sex percentiles and assign weight categories.

was a cluster-randomized trial to evaluate a cross-peer school-based obesity prevention program in Southern Appalachia. Undergraduate students from the disciplines of Kinesiology, Nutrition, and Public Health were trained as peer facilitators to deliver an 8-week curriculum in high school classes. The focus of the curriculum was on improving diet and physical activity with an additional emphasis on enhancing leadership and communication skills.

Background: Weight misperception has been documented among children although the impact on health risk behaviors is less understood, particularly among middle school students. The goals of this study were to describe sociodemographic differences in actual and perceived weight, correspondence between actual and perceived weight, and weight-related health risk behaviors, as well as to examine weight misperception and interactions with sociodemographic variables in explaining weight-related health risk behaviors.

Methods: Participants were recruited at 11 public school districts participating in the Tennessee Coordinated School Health (CSH) pilot program.

Both researchers and primary care providers vary in their methods for assessing weight status in infants. The purpose of the present investigation was to compare standing-height-derived to recumbent-length-derived weight-for-length standardized (WLZ) scores, using the WHO growth curves, in a convenience sample of infants who visited the lab at 18 and 21 months of age. Fifty-eight primarily White, middle class infants (25 girls) from a semi-rural region of southern Appalachia visited the lab at 18 months, with 45 infants returning 3 months later.

Article Synopsis
  • The study aimed to explore how different methods of defining weight misperception in adolescents impact results, comparing self-reports and actual body weight measurements.
  • Data came from a school-based obesity prevention program in southern Appalachia, involving 1,509 predominantly white ninth graders.
  • The findings indicated significant differences in weight misperception based on the method used, emphasizing the importance for researchers to consider these differences when interpreting results.

Background: Health-related quality of life (HRQoL) has been recognized as an important target and health outcome in obesity research. The current study aimed to examine HRQoL in overweight or obese children after a 10-week primary-care-based weight management program, Parent-Led Activity and Nutrition for Healthy Living, in southern Appalachia.

Methods: Sixty-seven children (ages 5-12 years) and their caregivers were recruited from four primary care clinics, two of which were randomized to receive the intervention.

Objectives: This study examined the relation of multiple aspects of the home food environment to dietary intake and body weight among overweight and obese children in southern Appalachia.

Methods: The study used baseline data from a cluster-randomized controlled trial, Parent-Led Activity and Nutrition for Healthy Living, evaluating a parent-mediated approach to treating child overweight and obesity in the primary care setting in southern Appalachia. Sixty-seven children ages 5 to 11 years were recruited from four primary care clinics.

Background: School-based interventions hold promise for child obesity prevention. Implemented as a part of the Winning With Wellness obesity prevention project, the "Go Slow Whoa" meal pattern (GSW) was designed to promote healthier foods in school cafeterias. This investigation determined perceived program effectiveness and impact on student's food purchases.

In the past few decades, there has been a move toward integrating behavioral health and medical services. This can be particularly beneficial for rural residents, as integration can increase access to mental healthcare in areas where there are shortages of mental health providers. Southern Appalachia is characterized by isolated areas that have shortages of both mental health and medical providers.

Child obesity has become an important public health concern, especially in rural areas. Primary care providers are well positioned to intervene with children and their parents, but encounter many barriers to addressing child overweight and obesity. This paper describes the design and methods of a cluster-randomized controlled trial to evaluate a parent-mediated approach utilizing physician's brief motivational interviewing and parent group sessions to treat child (ages 5-11 years) overweight and obesity in the primary care setting in Southern Appalachia.

Objective: To examine family context in relation to body image, weight concerns, and weight control behaviors in preadolescent African American girls.

Methods: Cross-sectional baseline data were analyzed from 303 African American girls 8 to 10 years old and a caregiver in the Girls health Enrichment Multi-site Studies Phase 2(GEMS), an obesity prevention intervention trial.

Results: Fruit, juice, and vegetable accessibility and family support for healthy eating and physical activity were significantly related to girls' body image and weight control behaviors.

This review evaluated psychological treatments for Anorexia Nervosa, Bulimia Nervosa, and Binge Eating Disorder conducted in primary care. Five studies met inclusion criteria. Guided self-help cognitive-behavioral therapy via a self-help book may be a beneficial, first-line treatment for reducing binging and purging symptoms.

School-based efforts to promote physical activity and healthier eating are a potentially effective approach to decreasing child obesity in rural populations. This article describes follow-up data on student activity and eating behaviors 4 years after implementation of the Winning with Wellness obesity prevention initiative. This project was based on the Centers for Disease Control and Prevention's coordinated school health model and used a community-based participatory research approach to address health behaviors in rural Appalachian elementary students.

Methods: Parents presenting to pediatric primary care clinics completed a rating scale (Pediatric Symptom Checklist) of psychosocial problems for their child.

Results: Approximately 21% of all rating scales were in the clinically significant range.

Objective: Clear evidence suggests that lifestyle interventions can be helpful in the treatment of youth who are overweight, but translational research is needed to address the gap between treatment research and clinical care.

Design: This meta-analysis integrated the results of 66 treatment-control comparisons and 59 alternate treatment comparisons evaluating lifestyle interventions for children and adolescents who were overweight.

Main Outcome Measures: Between-groups differences in weight-related outcomes and other health-related behaviors at the end of treatment.

Treatment studies provide minimal support for nicotine replacement therapy (NRT) with youth; however, survey studies suggest that adolescents use NRT, and may engage in inappropriate use. The current study sought to examine patterns of NRT use and risk factors for use to further aid smoking cessation efforts including prevention of potential misuse. In-school surveys assessing socio-demographic and behavioral factors associated with NRT use, gum or patch, were completed by 4078, predominantly African American, high school students.
