OBJECTIVE To examine obesity diagnosis, obesity-related counseling, and laboratory testing rates among obese pediatric patients seen in US preventive outpatient visits and to determine patient, provider, and practice-level factors that are associated with obesity diagnosis. METHODS By using 2005–2007 National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey data, outpatient preventive visits made by obese (body mass index ≥95%) 2- to 18-year-old patients were examined for frequencies of obesity diagnosis, diet, exercise, or weight reduction counseling, and glucose or cholesterol testing. Multivariable logistic regression was used to examine whether patient-level (gender, age, race/ethnicity, insurance type) and provider/practice-level (geographic region, provider specialty, and practice setting) factors were associated with physician obesity diagnosis. RESULTS Physicians documented an obesity diagnosis in 18% (95% confidence interval, 13–23) of visits made by 2- to 18-year-old patients with a body mass index ≥95%. Documentation of an obesity diagnosis was more likely for non-white patients (odds ratio 2.87; 95% confidence interval, 1.3–6.3). Physicians were more likely to provide obesity-related counseling (51% of visits) than to conduct laboratory testing (10% of visits) for obese pediatric patients. CONCLUSIONS Rates of documented obesity diagnosis, obesity-related counseling, and laboratory testing for comorbid conditions among obese pediatric patients seen in US outpatient preventive visits are suboptimal. Efforts should target enhanced obesity diagnosis as a first step toward improving pediatric obesity management.

Laminitis is a common debilitating disease in horses that involves painful disruption of the lamellar dermo-epidermal junction within the hoof. This condition is often refractory to conventional anti-inflammatory analgesia and results in unremitting pain, which in severe cases requires euthanasia. The mechanisms underlying pain in laminitis were investigated using quantification of behavioural pain indicators in conjunction with histological studies of peripheral nerves innervating the hoof. Laminitic horses displayed consistently altered or abnormal behaviours such as increased forelimb lifting and an increased proportion of time spent at the back of the box compared to normal horses. Electron micrographic analysis of the digital nerve of laminitic horses showed peripheral nerve morphology to be abnormal, as well as having reduced numbers of unmyelinated (43.2%) and myelinated fibers (34.6%) compared to normal horses. Sensory nerve cell bodies innervating the hoof, in cervical, C8 dorsal root ganglia (DRG), showed an upregulated expression of the neuronal injury marker, activating transcription factor-3 (ATF3) in both large NF-200-immunopositive neurons and small neurons that were either peripherin- or IB4-positive. A significantly increased expression of neuropeptide Y (NPY) was also observed in myelinated afferent neurons. These changes are similar to those reported in other neuropathic pain states and were not observed in the C4 DRG of laminitic horses, which is not associated with innervation of the forelimb. This study provides novel evidence for a neuropathic component to the chronic pain state associated with equine laminitis, indicating that anti-neuropathic analgesic treatment may well have a role in the management of this condition.

BACKGROUND AND OBJECTIVE: Hypertension occurs in 2% to 5% of children in the United States, and its prevalence has increased during the obesity epidemic. There is no consensus among professional organizations about how frequently blood pressure should be measured in children >3 years old. The purpose of this study was to estimate the frequency of hypertension screening during ambulatory pediatric visits in the United States and to determine patient- and provider-level factors associated with screening during visits specifically for preventive care. METHODS: We analyzed data from a nationally representative sample of ambulatory visits by using the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey from 2000 through 2009. In the subset of visits involving patients aged 3 to 18 years, we estimated the frequency of screening during all visits, preventive visits, and preventive visits in which overweight/obesity was diagnosed. We used multivariable logistic regression to identify patient- and provider-level factors associated with screening. RESULTS: Hypertension screening occurred during 35% of ambulatory pediatric visits, 67% of preventive visits, and 84% of preventive visits in which overweight/obesity was diagnosed. Between 2000 and 2009, the frequency of screening increased in all visits and in preventive visits. Factors independently associated with screening included older age and overweight/obesity diagnosis. CONCLUSIONS: Providers do not measure blood pressure in two-thirds of pediatric visits and one-third of pediatric preventive visits. Providers may understand the importance of screening among overweight/obese children; however, efforts to encourage routine screening, particularly in young children, may be needed.

IntroductionUS legislation requires that schools offer free drinking water where meals are served. However, little information is available about what types of water delivery systems schools should install to meet such requirements. The study objective was to examine the efficacy and cost of 2 water delivery systems (water dispensers and bottleless water coolers) in increasing students’ lunchtime intake of water in low-income middle schools.MethodsIn 2013, twelve middle schools in the San Francisco Bay Area participated in a cluster randomized controlled trial in which they received 6 weeks of promotional activities, received provision of cups, and were assigned to 1 of 2 cafeteria water delivery systems: water dispensers or bottleless water coolers (or schools served as a control). Student surveys (n = 595) and observations examined the interventions’ effect on students’ beverage intake and staff surveys and public data assessed intervention cost.ResultsAnalysis occurred from 2013 through 2015. Mixed-effects logistic regression, accounting for clustering and adjustment for student sociodemographic characteristics, demonstrated a significant increase in the odds of students drinking water in schools with promotion plus water dispensers and cups (adjusted odds ratio = 3.1; 95% confidence interval, 1.4–6.7; P = .004) compared with schools with traditional drinking fountains and no cups or promotion. The cost of dispenser and bottleless water cooler programs was similar ($0.04 per student per day).ConclusionInstead of relying on traditional drinking fountains, schools should consider installing water sources, such as plastic dispensers with cups, as a low-cost, effective means for increasing students’ water intake.
