Background Poor dietary habits and decreased outdoor activity has led to an epidemic of obese children and vitamin D deficiency. The lack of vitamin D alters bone development and mineralization by diminishing physiological levels of calcium and phosphorus. Given vitamin Ds role in bone and growth plate mineralization and regulation, we hypothesized that vitamin D deficiency would lead to higher rates of fractures, slipped capital femoral epiphysis (SCFE), and Blount disease in obese youth. Methods A retrospective review was performed at the obesity clinic using the obesity database (890 patients). Data obtained included body mass index (BMI), vitamin D levels (25-vitamin D), history of fractures, Blount disease, and/or SCFE. The chart review identified 2 populations of obese patients, those with vitamin D deficiency, <16 ng/mL (198 patients) and those not vitamin D deficient >16 ng/mL (692 patients). Fisher exact, &khgr;2, and 2-sample t tests along with logistic regression were used for statistical analysis. A P value ⩽0.05 was considered statistically significant. Results Blount disease was found to have a statistically significant (P<0.05) positive association with patients sex, BMI, and vitamin D level. Specifically, males were 8.16 times more likely than females to be observed with Blount disease (P=0.01). Patients with very low vitamin D levels were 7.33 times more likely to have Blount disease than patients with higher levels (P=0.002). Each whole number increase in BMI increases the likelihood of Blount disease by 3% (P=0.01). There was no association between increased number of fractures or SCFE with vitamin D deficiency in these obese patients. Conclusion As our findings indicate, BMI and vitamin D levels have a strong association with Blount disease, which may be especially important among males. Ours is the first study to show a relationship between vitamin D deficiency and Blount disease, but further prospective studies are needed with larger numbers to confirm this independent association of vitamin D deficiency with Blount disease. Level of Evidence Level III retrospective study.

Objective. To examine the results of an interventionist approach applied to human immunodeficiency virus (HIV)-infected children for whom caregiver nonadherence was suspected as the cause of treatment failure. Methods. The medical records of a cohort of 16 perinatally HIV-infected children whose care was managed at the Arkansas Children’s Hospital Pediatric HIV Clinic for an uninterrupted period of ≥3 years were reviewed through July 2003. Data collected included date of birth, dates of and explanations for clinic visits and hospitalizations, dates of laboratory evaluations, CD4+ T cell percentages, plasma HIV-1 RNA levels, antiretroviral medications, viral resistance tests (eg, phenotype and genotype), and physician-initiated interventions to enhance adherence to the medication regimen. A stepwise interventionist approach was undertaken when patients continued to demonstrate high viral loads, despite documented viral sensitivity to the medication regimen and caregivers’ insistence that medications were being administered regularly. Step 1 was prescribing a home health nurse referral, step 2 was administering directly observed therapy (DOT) while the patient was hospitalized for 4 days, and step 3 was submitting a physician-initiated medical neglect report to the Arkansas Department of Human Services. Results. The results for 6 patients for whom this stepwise approach was initiated are reported. Home health nurse referrals failed to result in sustained improvements in adherence in all 6 cases. Viral load assays performed before and after DOT provided an objective measure of the effect of adherence, with 12 hospitalizations resulting in a mean ± SD decrease in HIV RNA levels of 1.09 ± 0.5 log10 copies per mL, with a range of 0.6 to 2.1 log10 copies per mL. Four families responded to DOT hospitalization, and sustained decreases in the respective patients’ viral loads were noted. In 2 cases, medical neglect reports were submitted when DOT did not result in improved adherence. These patients were eventually placed in foster care, with subsequent improvements in their viral loads and CD4+ T cell percentages. Conclusions. Nonadherence with antiretroviral therapy can be established on the basis of persistently elevated HIV RNA levels that decrease with DOT. Nonadherence poses a danger to the child that is grave and potentially irreversible. Caregivers should be offered all available resources to help them adhere to a sound treatment plan. In cases of demonstrated inability to provide needed care, it is necessary to consider seeking child protection, even for apparently healthy children.

Large gaps exist in the capacity of the US medical system to participate meaningfully in childhood obesity-prevention efforts and to meet the treatment needs of obese children. Current primary care practice for the prevention and treatment of childhood obesity often varies from evidence-based recommendations. Childhood obesity specialists have partnered successfully with schools of medicine, professional societies, and other organizations to collaboratively engage with primary care providers in quality improvement for obesity prevention and treatment. This review and commentary targets 2 audiences. For childhood obesity experts and their organizational partners, methods to support change in primary practice and the evidence supporting their use are outlined. For primary care providers and non–obesity specialists, effective strategies for changing practice and the potential benefits of addressing childhood obesity systematically are discussed.

Obese children and adolescents have unique needs for specialized medical equipment while hospitalized and might require special diets and physical activity options as part of their medical treatment. It is important that patients with a diagnosis of obesity be identified on admission so that appropriate equipment and resources can be provided. We examined what components a healthy hospital environment should include and sought to determine if childrens hospitals provide a healthy hospital environment that offers these components. In addition, we sought to determine if childrens hospitals have policies in place to identify children with obesity so that appropriate resources and services can be offered to treat that diagnosis. We surveyed National Association of Childrens Hospitals and Related Institutions member hospitals via a Web-based questionnaire and found that the majority of them do not have policies in place to identify patients with obesity. We did find that the majority of hospitals reported innovative programs or services to provide a healthy hospital environment for their patients, visitors, and staff but acknowledged limitations in providing some services. Specifically, childrens hospitals can and should improve on their identification and management of obese pediatric patients.

The increasing prevalence of pediatric overweight has caused the medical community to begin searching for ways to deal with this new pediatric medical problem. The Centers for Disease Control developed the Body Mass Index (BMI) growth charts, which came into use in 2000. Primary care providers are seeking education on this relatively new topic. This article provides fundamental information based on the medical evidence for pediatricians to learn how to care for their overweight pediatric patients in the office setting.
