Objective To examine the health-related QOL of obese children and adolescents compared with children and adolescents who are healthy or those diagnosed as having cancer.Design, Setting, and Participants Cross-sectional study of 106 children and adolescents (57 males) between the ages of 5 and 18 years (mean [SD], 12.1 [3] years), who had been referred to an academic children's hospital for evaluation of obesity between January and June 2002. Children and adolescents had a mean (SD) body mass index (BMI) of 34.7 (9.3) and BMI z score of 2.6 (0.5). Main Outcome MeasuresChild self-report and parent proxy report using a pediatric QOL inventory generic core scale (range, 0-100). The inventory was administered by an interviewer for children aged 5 through 7 years. Scores were compared with previously published scores for healthy children and adolescents and children and adolescents diagnosed as having cancer.Results Compared with healthy children and adolescents, obese children and adolescents reported significantly (PϽ.001) lower health-related QOL in all domains (mean [SD] total score, 67 [16.3] for obese children and adolescents; 83 [14.8] for healthy children and adolescents). Obese children and adolescents were more likely to have impaired health-related QOL than healthy children and adolescents (odds ratio [OR], 5.5; 95% confidence interval [CI], 3.4-8.7) and were similar to children and adolescents diagnosed as having cancer (OR, 1.3; 95% CI, 0.8-2.3). Children and adolescents with obstructive sleep apnea reported a significantly lower health-related QOL total score (mean [SD], 53.8 [13.3]) than obese children and adolescents without obstructive sleep apnea (mean [SD], 67.9 [16.2]). For parent proxy report, the child or adolescent's BMI z score was significantly inversely correlated with total score (r=−0.246; P = .01), physical functioning (r=−0.263; PϽ.01), social functioning (r=−0.347; PϽ.001), and psychosocial functioning (r=−0.209; P = .03). ConclusionsSeverely obese children and adolescents have lower health-related QOL than children and adolescents who are healthy and similar QOL as those diagnosed as having cancer. Physicians, parents, and teachers need to be informed of the risk for impaired health-related QOL among obese children and adolescents to target interventions that could enhance health outcomes.
Fatty liver is the most common liver abnormality in children age 2 to 19 years. The presence of macrovesicular hepatic steatosis in approximately 1 of every 10 children has important ramifications for the long-term health of children and young adults. The influence of the risk factors identified should be taken into consideration in the development of protocols designed to screen at-risk children and adolescents.
Nonalcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease that occurs in the setting of insulin resistance and increased adiposity. It has rapidly evolved into the most common liver disease seen in the pediatric population and is a management challenge for general pediatric practitioners, subspecialists and for health systems. In this guideline, the expert committee on NAFLD (ECON) reviewed and summarized the available literature, formulating recommendations to guide screening and clinical care of children with NAFLD.
Context Nonalcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in US children and adolescents and can present with advanced fibrosis or non-alcoholic steatohepatitis (NASH). No treatment has been established. Objective To determine whether children with NAFLD would improve from therapeutic intervention with vitamin E or metformin. Design, Setting, and Patients Randomized, double-blind, double-dummy, placebo-controlled clinical trial conducted at 10 university clinical research centers in 173 patients (aged 8–17 years) with biopsy-confirmed NAFLD conducted between September 2005 and March 2010. Interventions Daily dosing of 800 IU of vitamin E (58 patients), 1000 mg of metformin (57 patients), or placebo (58 patients) for 96 weeks. Main Outcome Measures The primary outcome was sustained reduction in alanine aminotransferase (ALT) defined as 50% or less of the baseline level or 40 U/L or less at visits every 12 weeks from 48 to 96 weeks of treatment. Improvements in histological features of NAFLD and resolution of NASH were secondary outcome measures. Results Sustained reduction in ALT level was similar to placebo (10/58; 17%; 95% CI, 9% to 29%) in both the vitamin E (15/58; 26%; 95% CI, 15% to 39%; P=.26) and metformin treatment groups (9/57; 16%; 95% CI, 7% to 28%; P=.83). The mean change in ALT level from baseline to 96 weeks was −35.2 U/L (95% CI, −56.9 to −13.5) with placebo vs −48.3 U/L (95% CI, −66.8 to −29.8) with vitamin E (P=.07) and −41.7 U/L (95% CI, −62.9 to −20.5) with metformin (P=.40). The mean change at 96 weeks in hepatocellular ballooning scores was 0.1 with placebo (95% CI, −0.2 to 0.3) vs −0.5 with vitamin E (95% CI, −0.8 to −0.3; P=.006) and −0.3 with metformin (95% CI, −0.6 to −0.0; P=.04); and in NAFLD activity score, −0.7 with placebo (95% CI, −1.3 to −0.2) vs −1.8 with vitamin E (95% CI, −2.4 to −1.2; P=.02) and −1.1 with metformin (95% CI, −1.7 to −0.5; P=.25). Among children with NASH, the proportion who resolved at 96 weeks was 28% with placebo (95% CI, 15% to 45%; 11/39) vs 58% with vitamin E (95% CI, 42% to 73%; 25/43; P=.006) and 41% with metformin (95% CI, 26% to 58%; 16/39; P=.23). Compared with placebo, neither therapy demonstrated significant improvements in other histological features. Conclusion Neither vitamin E nor metformin was superior to placebo in attaining the primary outcome of sustained reduction in ALT level in patients with pediatric NAFLD.
