Predictors of Health-Related Quality of Life in Obese Youth

Objective: Recent literature has documented the psychosocial consequences of pediatric obesity, including poor health‐related quality of life (HRQOL). The present study examines HRQOL and its association with depressive symptoms and perceived social support in African‐American and white youth pursuing weight management treatment.

Controlled Study of Critical Parent and Family Factors in the Obesigenic Environment

Objective: Critical gaps remain in our understanding of the obesigenic family environment. This study examines parent and family characteristics among obese youth presenting for treatment in a clinic setting.

Pediatric Self-management: A Framework for Research, Practice, and Policy

Self-management of chronic pediatric conditions is a formidable challenge for patients, families, and clinicians, with research demonstrating a high prevalence of poor self-management and nonadherence across pediatric conditions. Nevertheless, effective self-management is necessary to maximize treatment efficacy and clinical outcomes and to reduce unnecessary health care utilization and costs. However, this complex behavior is poorly understood as a result of insufficient definitions, reliance on condition-specific and/or adult models of self-management, failure to consider the multitude of factors that influence patient self-management behavior, and lack of synthesis of research, clinical practice, and policy implications. To address this need, we present a comprehensive conceptual model of pediatric self-management that articulates the individual, family, community, and health care system level influences that impact self-management behavior through cognitive, emotional, and social processes. This model further describes the relationship among self-management, adherence, and outcomes at both the patient and system level. Implications for research, clinical practice, and health care policy concerning pediatric chronic care are emphasized with a particular focus on modifiable influences, evidence-based targets for intervention, and the role of clinicians in the provision of self-management support. We anticipate that this unified conceptual approach will equip stakeholders in pediatric health care to (1) develop evidence-based interventions to improve self-management, (2) design programs aimed at preventing the development of poor self-management behaviors, and (3) inform health care policy that will ultimately improve the health and psychosocial outcomes of children with chronic conditions.

Health-Related Quality of Life and Depressive Symptoms in Adolescents With Extreme Obesity Presenting for Bariatric Surgery

OBJECTIVE. We sought to document health-related quality of life (HRQoL) impairment and depressive symptomatology in adolescents with extreme obesity considering surgical weight loss. STUDY DESIGN. A retrospective review of clinical data was conducted for 33 consecutive extremely obese adolescents presenting for evaluation at a bariatric surgery program for adolescents. Adolescents completed the PedsQL and the Beck Depression Inventory. Mothers completed the parent-proxy PedsQL and the Child Behavior Checklist. RESULTS. HRQoL scores from both informants were markedly impaired relative to published norms on healthy youth. Moderate agreement was found for self-reported and parent-proxy HRQoL. Approximately 30% of youth met criteria for clinically significant depressive symptoms when based on self-report and 45% of youth when based on mother report. Only 21% of youth were currently engaged in some form of psychological treatment (eg, medication or therapy). CONCLUSIONS. The day-to-day life of adolescents with extreme obesity seeking bariatric surgery is globally and severely impaired. However, only some of these adolescents demonstrate clinically significant levels of depressive symptomatology. These data will be critical to the development of more informed patient selection criteria and more efficacious treatment paradigms for this vulnerable pediatric subgroup.

Assessing Weight‐Related Quality of Life in Adolescents

Objective: The development of a new weight‐related measure to assess quality of life in adolescents [Impact of Weight on Quality of Life (IWQOL)‐Kids] is described.

Patterns of nonadherence to antiepileptic drug therapy in children with newly diagnosed epilepsy.

CONTEXT Because of epilepsys common occurrence, the narrow therapeutic and safety margins of antiepileptic medications, and the recognized complications of medication nonadherence in adults with epilepsy, identifying the rates, patterns, and predictors of nonadherence in children with epilepsy is imperative. The onset and evolution of antiepileptic drug nonadherence in children with newly diagnosed epilepsy remains unknown. OBJECTIVES To identify and characterize trajectories of adherence in children with newly diagnosed epilepsy over the first 6 months of therapy and to determine sociodemographic and epilepsy-specific predictors of adherence trajectories. DESIGN, SETTING, AND PATIENTS Prospective, longitudinal observational study of antiepileptic drug adherence in a consecutive cohort of 124 children (2-12 years old) with newly diagnosed epilepsy at Cincinnati Childrens Hospital Medical Center. Patients were recruited from April 2006 through March 2009, and final data collection occurred in September 2009. MAIN OUTCOME MEASURE Objective adherence measured using electronic monitors. RESULTS Fifty-eight percent of children with newly diagnosed epilepsy demonstrated persistent nonadherence during the first 6 months of therapy. Group-based trajectory models identified 5 differential adherence patterns (Bayesian information criterion = -23611.8): severe early nonadherence (13%; 95% confidence interval [CI], 8%-20%), severe delayed nonadherence (7%; 95% CI, 3%-12%), moderate nonadherence (13%; 95% CI, 8%-20%), mild nonadherence (26%; 95% CI, 19%-34%), and near-perfect adherence (42%; 95% CI, 33%-50%). The adherence pattern of most patients was established by the first month of therapy. Socioeconomic status was the sole predictor of adherence trajectory group status (χ(4)(2) = 19.3 [n = 115]; P < .001; partial r(2) = 0.25), with lower socioeconomic status associated with higher nonadherence. CONCLUSION Five trajectory patterns were identified that captured the spectrum of nonadherence to antiepileptic drugs among children with newly diagnosed epilepsy; the patterns were significantly associated with socioeconomic status.

Health-Related Quality of Life across Pediatric Chronic Conditions

OBJECTIVE To compare health-related quality of life (HRQOL) across 8 pediatric chronic conditions, including 5 understudied populations, and examine convergence between youth self-report and parent-proxy report. STUDY DESIGN Secondary data from 589 patients and their caregivers were collected across the following conditions: obesity, eosinophilic gastrointestinal disorder, inflammatory bowel disease, epilepsy, type 1 diabetes, sickle cell disease, post-renal transplantation, and cystic fibrosis. Youth and caregivers completed age-appropriate self-report and/or parent-proxy report generic HRQOL measures. RESULTS Youth diagnosed with eosinophilic gastrointestinal disorder and obesity had lower HRQOL than other pediatric conditions by parent report. Caregivers reported lower HRQOL by proxy report than youth self-reported across most subscales. CONCLUSIONS Use of brief, easily administered, and reliable assessments of psychosocial functioning, such as HRQOL, may provide clinicians additional opportunities for intervention or services targeting improved HRQOL relative to the needs of each population.

Psychosocial Functioning Improves Following Adolescent Bariatric Surgery

The aims of the present study were to examine changes in health‐related quality of life (HRQOL) and depressive symptoms in adolescents with extreme obesity undergoing Roux‐en‐Y gastric bypass (RYGBP) across the first postoperative year. A prospective longitudinal observational study of 31 adolescent patients undergoing RYGBP at a pediatric medical center (mean = 16.4 years; 64.5% females, mean BMI 63.5; 97% of study eligible and consecutive patients) was conducted. Participants completed two adolescent HRQOL measures, the PedsQL (generic) and the IWQOL‐Kids (weight‐related), the Beck Depression Inventory (BDI), and height and weight were measured at three time points: baseline, and 6 and 12 months following RYGBP. Prior to RYGBP, significant impairments in HRQOL were documented and 38.7% reported depressive symptomatology in the clinical range. As expected, BMI and depressive symptoms decreased and HRQOL improved from baseline to 12 months post‐RYGBP. Linear mixed modeling analyses detected several nonlinear slopes in BMI, depressive symptoms, and the majority of HRQOL domains over time with deceleration in these postoperative changes beginning at the 6th month time point. In contrast, the rate of change in weight‐related social relations was linear (e.g., no deceleration), indicating continued improvement across the first postoperative year. Adolescent RYGBP results in significant improvement in HRQOL and depressive symptomatology over the first postoperative year. Longer‐term follow‐up will be critical to determine adolescent weight and psychosocial trajectories, their interrelations, and what role psychosocial status plays in continued weight loss, maintenance, and regain.

Depressive symptoms in children with cystic fibrosis and parents and its effects on adherence to airway clearance

Little is currently known about the co‐morbidity of depression and cystic fibrosis (CF) and there is currently no empirical research on the effects of depressive symptoms on adherence in children and adolescents with CF. The primary aim of this study was to evaluate the extent of depressive symptoms in children and adolescents with CF and their parents, and determine whether depressive symptoms in the child and/or parent was associated with adherence to airway clearance. We also evaluated whether childrens perceptions of relational security with a parent were associated with adherence to airway clearance.

Family Functioning in the Context of Pediatric Chronic Conditions

Objective: The aims were to describe and compare generic family functioning in children with five different chronic conditions and healthy comparisons, and to examine the relations between family functioning and sociodemographic variables. Methods: A secondary data analysis from six independent studies including 301 children (cystic fibrosis: n = 59; obesity: n = 28; sickle cell disease: n = 44; inflammatory bowel disease: n = 43; epilepsy: n = 70; healthy comparison group: n = 57) was conducted. In each study, parents completed the Family Assessment Device. Results: Across all five chronic conditions, between 13% and 36% of families endorsed levels of functioning in the “unhealthy” range, with the greatest proportions in the following domains: communication, roles, and affective involvement. No significant group (i.e., between all six groups, namely five chronic conditions as well as healthy comparisons) differences were observed on Family Assessment Device scales (model F [35, 1335] = 0.81, p = .79). Older child age, fewer children living in the home, and lower household income were significantly related to poorer family functioning in the areas of communication, roles, affective involvement, and general functioning. Conclusions: Families of children with and without chronic conditions do not differ significantly from each other on generic family functioning. However, risk factors for poor family functioning include older child age, less children in the home, and lower household income. These risk factors combined with data suggesting that a subset of families exhibit “unhealthy functioning” warrants the need for close monitoring of how families function in the context of a pediatric condition.
