Neighborhood park access and park characteristics are associated with weight status in youth

This study investigated park access and park quality in the context of childhood obesity. Participants were 20,638 children ages 6-17y from a large primary care health system. Analyses tested associations of park access and park characteristics with children's weight status, and sociodemographic interactions. Both park access and the quality of nearest park were associated with a lower odds of having obesity. Park quality interacted with age, sex, and income. Findings suggest park access is important for supporting a healthy weight in children. Park quality may be most important among 12-14-year-olds, girls, and higher income groups.

Elevated blood pressure in youth in pediatric weight management programs in the Pediatric Obesity Weight Evaluation Registry (POWER)

Blood pressure (BP) assessment and management are important aspects of care for youth with obesity. This study evaluates data of youth with obesity seeking care at 35 pediatric weight management (PWM) programs enrolled in the Pediatric Obesity Weight Evaluation Registry (POWER). Data obtained at a first clinical visit for youth aged 3–17 years were evaluated to: (1) assess prevalence of BP above the normal range (high BP); and (2) identify characteristics associated with having high BP status. Weight status was evaluated using percentage of the 95^th percentile for body mass index (%BMIp95); %BMIp95 was used to group youth by obesity class (class 1, 100% to < 120% %BMIp95; class 2, 120% to < 140% %BMIp95; class 3, ≥140% %BMIp95; class 2 and class 3 are considered severe obesity). Logistic regression evaluated associations with high BP. Data of 7943 patients were analyzed. Patients were: mean 11.7 (SD 3.3) years; 54% female; 19% Black non‐Hispanic, 32% Hispanic, 39% White non‐Hispanic; mean %BMIp95 137% (SD 25). Overall, 48.9% had high BP at the baseline visit, including 60.0% of youth with class 3 obesity, 45.9% with class 2 obesity, and 37.7% with class 1 obesity. Having high BP was positively associated with severe obesity, older age (15–17 years), and being male. Nearly half of treatment‐seeking youth with obesity presented for PWM care with high BP making assessment and management of BP a key area of focus for PWM programs.

Translating Family-Based Behavioral Treatment for Childhood Obesity into a User-Friendly Digital Package for Delivery to Low-Income Families through Primary Care Partnerships: The MO-CORD Study

Background: Significant gaps exist in access to evidence-based pediatric weight management interventions, especially for low-income families. As a part of the Centers for Disease Control and Prevention's Childhood Obesity Research Demonstration project 3.0 (CORD), the Missouri CORD (MO-CORD) team aims to increase access to and dissemination of an efficacious pediatric obesity treatment, family-based behavioral treatment (FBT), among low-income families. This article describes the MO-CORD team's approach to translating FBT into a digital package for delivery to low-income families through primary care practices. Methods: Using digital technology, the primary care setting, and existing reimbursement mechanisms, the MO-CORD team is developing a scalable user-centered design informed treatment package of FBT. This package will be implemented in primary care clinics and delivered to children (5-12 years) with obesity from low-income households in rural and urban communities. The digital platform includes three main components: (1) provider and interventionist training, (2) interventionist-facing materials, and (3) family-facing treatment materials. User-centered design techniques and continuous iterative stakeholder feedback are utilized to emphasize tailoring to a low-income population, along with scalability and sustainability of the digital package. Conclusions: The MO-CORD project addresses the critical need to increase access to obesity treatment for children from low-income households and establishes a platform for future large-scale (i.e., nation-wide) dissemination of evidence-based pediatric weight-management interventions. This study determines whether the digital FBT package can be implemented within real-world settings to create a system by which children with obesity and their families can be effectively treated in primary care settings.

Implementation of a Scalable Family-Based Behavioral Treatment for Childhood Obesity Delivered through Primary Care Clinics: Description of the Missouri Childhood Obesity Research Demonstration Study Protocol

Background: Significant gaps exist in access to evidence-based pediatric weight management interventions, especially for low-income families who are disproportionately affected by obesity. As a part of the Centers for Disease Control and Prevention's Childhood Obesity Research Demonstration project (CORD 3.0), the Missouri team (MO-CORD) aims to increase access to and dissemination of an efficacious pediatric obesity treatment, specifically family-based behavioral treatment (FBT), for low-income families. Methods/Design: The implementation pilot study is a multisite matched-comparison group pilot of packaged FBT in pediatric clinics for low-income children with obesity, of ages 5 to 12 years old. The study is implemented in two Missouri pediatric primary care clinical sites, Freeman Health System Pediatric Clinics (rural Joplin) and Children's Mercy Hospital Pediatric Clinics (urban Kansas City). The design focuses on pragmatism through utilization of PRECIS (Pragmatic Explanatory Continuum Indicator Summary) domains, such as open eligibility criteria, limited follow-up intensity, reliance on medical records for creating a usual care comparison group data, and unobtrusive measurement of participant and provider adherence. The evaluation focuses on effectiveness as well as implementation outcomes and barriers to inform implementation scale up. Conclusions: Findings from this study will advance both science and practice by providing novel and immediately useful information to families, health care providers, health care organizations, payers, and other state Medicaid plans by developing and optimizing evidence-based pediatric weight management treatment for implementation and dissemination in health systems to address health disparities among low-income populations most affected by overweight and obesity.

Health-Related Quality of Life across Recent Pediatric Obesity Classification Recommendations

Extreme body mass index (BMI) values (i.e., above the 97th and below the 3rd percentiles) are inaccurately represented on the Centers for Disease Control and Prevention's growth curves, which may limit the utility of BMI percentile and BMI z-score for capturing changes in clinical outcomes for patients at extreme weights. Modeling child obesity severity based upon the percentage of BMI in excess of the 95th percentile (BMI95pct) has been proposed as an improved metric to better capture variability in weight at extreme ends of growth curves, which may improve our understanding of relationships between weight status and changes in clinical outcomes. However, few studies have evaluated whether the use of BMI95pct would refine our understanding of differences in clinical psychosocial constructs compared to previous methods for categorization. This cross-sectional study evaluated child obesity severity based on BMI95pct to examine potential group differences in a validated, obesity-specific measure of Health-Related Quality of Life (HRQoL). Four hundred and sixty-five children with obesity completed Sizing Me Up, a self-report measure of HRQoL. Children were classified into categories based on BMI95pct (i.e., class I: ≥100% and <120%; class II: ≥120% and <140%; class III: ≥140%). The results indicate that children with class III obesity reported lower HRQoL than children with class I and class II obesity; however, there were no differences between Class II and Class I. In much of the previous literature, children with class II and class III obesity are often combined under the category "Severe Obesity" based upon BMI above the 99th percentile. This study suggests that grouping children from various classes together would neglect to capture critical differences in HRQoL. Future research including children with severe obesity should consider obesity classes to best account for functioning and clinical outcomes.

Community Healthcare and Technology to Enhance Communication in Pediatric Obesity Care

Childhood obesity continues to be a critical healthcare issue and a paradigm of a pervasive chronic disease affecting even our youngest children. When considered within the context of the socioecological model, the factors that influence weight status, including the social determinants of health, limit the impact of multidisciplinary care that occurs solely within the medical setting. Coordinated care that incorporates communication between the healthcare and community sectors is necessary to more effectively prevent and treat obesity. In this article, the Expert Exchange authors, with input from providers convened at an international pediatric meeting, provide recommendations to address this critical issue. These recommendations draw upon examples from the management of other chronic conditions that might be applied to the treatment of obesity, such as the use of care plans and health assessment forms to allow weight management specialists and community personnel (e.g., school counselors) to communicate about treatment recommendations and responses. To facilitate communication across the healthcare and community sectors, practical considerations regarding the development and/or evaluation of communication tools are presented. In addition, the use of technology to enhance healthcare-community communication is explored as a means to decrease the barriers to collaboration and to create a web of connection between the community and healthcare providers that promote wellness and a healthy weight status.

Application of the Medical Neighborhood to Children with Severe Obesity

BACKGROUND

Growth in the prevalence of severe pediatric obesity and tertiary care pediatric weight management programs supports the application of chronic disease management models to the care of children with severe obesity. One such model, the medical neighborhood, aims to optimize care coordination between primary and tertiary care by applying principles of the Patient-Centered Medical Home to all providers.

METHODS

An exploration of the literature was performed describing effective programs, approaches, and coordinated care models applied to pediatric weight management and other chronic conditions.

RESULTS

Though there was a paucity of literature discovered with applications specific to pediatric weight management, relevant disease management and care coordination approaches were found. Proposed applications to the care of children with severe obesity can be made.

CONCLUSION

The application of the medical neighborhood framework, with its inclusion of healthcare and community partners, may optimize the management of children with severe obesity.

Expectations for Treatment in Pediatric Weight Management and Relationship to Attrition

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, 405 parents/guardians were recruited and reported about their children (203 adolescents, 202 children <12 years). Of the 203 adolescents, 160 also self-reported. Attrition rate was 42.2% at 3 months. For adolescents, greater interest in family support/behavior skills was associated with decreased odds of attrition at 3 months [odds ratio (OR) 0.75, 95% confidence interval (CI) 0.57-0.98, p = 0.04]. The more discordant the parent/adolescent dyad responses in this category, the higher the odds of attrition at 3 months (OR 1.36, 95% CI 1.04-1.78, p = 0.02). Weight loss was an important weight management goal for both adolescents and parents. For adolescents with this goal, the median weight-loss goal was 50 pounds. Attrition was associated with adolescent weight-loss goals above the desired median (50% above the median vs. 28% below the median, p = 0.02).

CONCLUSIONS

Assessing initial expectations may help tailor treatment to meet families' needs, especially through focus on family-based change and realistic goal setting.

Patient Attendance and Outcomes in a Structured Weight Management Program

OBJECTIVES

To determine service utilization and identify patient characteristics associated with service utilization in youth with obesity presenting for structured weight management, and to explore weight-related outcomes associated with service utilization.

STUDY DESIGN

In this retrospective study conducted between January 2008 and December 2013, we examined variables associated with the care of 2089 patients aged 2-18 years presenting for an initial visit to 2 tertiary care-based, multidisciplinary structured weight management clinics.

RESULTS

Only 53% of patients returned for a second visit, 29% returned for a third visit, and virtually none (0.5%) completed the recommended 6 visits within 6 months. Patients who were Hispanic, government-insured, and whose parent/s spoke Spanish were more likely to return to clinic. Of those patients who returned for at least a second visit, 70% demonstrated a reduction in or maintenance of body mass index z-score.

CONCLUSIONS

Patient retention remains a significant barrier to effective pediatric weight management. Structured weight management programs should increase their efforts to engage patients and families at the initial visit and identify and address barriers to follow up.

Comparison of a condensed 12-week version and a 24-week version of a family-based pediatric weight management program

BACKGROUND

The current study compares the effectiveness of a condensed 12-week version and a 24-week version of the same pediatric behavioral weight management program.

METHODS

Children (n=162) between the ages of 8 and 18 years (baseline BMIz=2.39; standard deviation=0.29) were randomized to either a 12- or 24-week version of the same behavioral weight management program. Child anthropometric data were recorded at baseline, 6 weeks, 12 weeks, 24 weeks, and 12 months. A two-level longitudinal model was used to examine within- and between-group differences in BMIz change over time.

RESULTS

A significant group-by-time interaction was found (β=-0.01; standard error, <0.01; p<0.01) with the 24-week group showing greater reductions in BMIz. Children in the 24-week group showed significant BMIz reductions over time (z=-5.18; p<0.01), but children in the 12-week group did not (z=-0.85; p=0.39).

CONCLUSIONS

Children in the 24-week program demonstrated greater reductions in BMIz than children in the 12-week group. Therefore, there may be additional benefit to sessions above and beyond the 8- to 12-week minimum suggested for pediatric weight management programs.

Insurer and employer views on pediatric obesity treatment: a qualitative study

OBJECTIVE

The effectiveness of group-based comprehensive, multidisciplinary (stage 3) pediatric weight management programs is backed by a growing body of literature, yet insurance coverage of these programs is scarce to nonexistent, limiting their reach and long-term survival. The objective of this study was to better understand the perspectives of insurers and large employers on the issue of group-based treatment coverage.

DESIGN AND METHODS

The authors performed a qualitative study utilizing structured interviews with these stakeholders, following accepted techniques.

RESULTS

Six major themes emerged: cost, program effectiveness, corporate social responsibility, secondary parental (employee) benefits, coverage options and new benefit determination.

CONCLUSION

Future efforts to secure payment for group-based pediatric weight management programs should address these key themes.

Childhood obesity: survey of physician assessment and treatment practices

BACKGROUND

This study examined physician experience with the 2007 Expert Committee Recommendations (ECR) on the Assessment, Prevention and Treatment of Child and Adolescent Overweight and Obesity.

METHODS

Pediatricians and family physicians (n = 194) practicing in the Midwest completed a survey designed to assess knowledge of, adherence to, and self-efficacy in implementing the 2007 Expert Committee recommendations.

RESULTS

The majority of physicians (71%) were aware of the ECR and adhered to approximately 60% of the recommendations. Adherence was significantly higher for physicians who were aware of the ECR. Differences in awareness of and adherence to the ECR were noted among physician groups by specialty and location. Self-efficacy for assessing and treating pediatric obesity was significantly positively correlated with adherence to the ECR (Pearson r = 0.46). When asked for strategies that would facilitate improved pediatric weight management, physicians most often reported desiring to learn effective methods to increase patient motivation.

CONCLUSIONS

Efforts to improve adherence to the Expert Committee recommendations should focus on improving physician awareness of and training in the use of the recommendations and on improved training and development of self-efficacy in pediatric weight assessment and patient counseling skills.

Resource Utilization and Expenditures for Overweight and Obese Children

OBJECTIVES

To compare health care utilization and expenditures for healthy-weight patients, overweight patients, and patients with diagnosed and undiagnosed obesity and to examine factors associated with a diagnosis of obesity.

DESIGN

Retrospective study using claims data from a large pediatric integrated delivery system.

SETTING

An urban academic children's hospital.

PARTICIPANTS

Children aged 5 to 18 years who presented to a primary care clinic for well-child care visits during the calendar years 2002 and 2003 and who were followed up for 12 months.

MAIN OUTCOME MEASURES

Diagnosis of obesity, primary care visits, emergency department visits, laboratory use, and health care charges.

RESULTS

Of 8404 patients, 57.9% were 10 years or older, 61.2% were African American, and 72.9% were insured by Medicaid. According to the criteria of body mass index (calculated as weight in kilograms divided by the square of height in meters), 17.8% were overweight and 21.9% were obese. Of the obese children, 42.9% had a diagnosis of obesity. Increased laboratory use was found in both children with diagnosed obesity (odds ratio [OR], 5.49; 95% confidence interval [CI], 4.65-6.48) and children with undiagnosed obesity (OR, 2.32; 95% CI, 1.97-2.74), relative to the healthy-weight group. Health care expenditures were significantly higher for children with diagnosed obesity (adjusted mean difference, $172; 95% CI, $138-$206) vs the healthy-weight group. Factors associated with the diagnosis of obesity were age 10 years and older (OR, 2.7; 95% CI, 2.0-3.4), female sex (OR, 1.5; 95% CI, 1.2-1.8), and having Medicaid (OR, 1.6; 95% CI, 1.1-2.3).

CONCLUSIONS

Increased health care utilization and charges reported in obese adults are also present in obese children. Most children with obesity had not been diagnosed as having obesity in this administrative data set.
