Preventing and treating obesity: pediatricians' self-efficacy, barriers, resources, and advocacy.

OBJECTIVE: With respect to obesity prevention and treatment, to determine pediatricians' 1) treatment self-efficacy; 2) perceived barriers and relationships to management self-efficacy; 3) desired resources; and 4) willingness to be involved in advocacy. METHODOLOGY: A cross-sectional, self-administered mail survey queried members of the North Carolina Pediatrics Society and the American Academy of Pediatrics who were practicing routine care. RESULTS: The adjusted response rate was 71% (n = 356). Only 12% of respondents reported high self-efficacy in obesity management, yet 39% believed that physicians could potentially be effective. The most frequently encountered barriers to obesity management included availability of fast food (97%) and soft drinks (95%). However, some practice-based barriers were most strongly associated with self-efficacy. Odds of high self-efficacy were lower for respondents who reported lack of non-MD staff reimbursement (odds ratio [OR] = 0.73; 95% confidence interval [CI] = 0.58, 0.92), lack of on-site dietitian (OR = 0.65; 95% CI = 0.50, 0.83), or lack of patient educational materials (OR = 0.67; 95% CI = 0.50, 0.89), compared with those who reported encountering these barriers infrequently. Respondents chose better counseling tools (96%) as the most helpful clinical resource for obesity management. Most (89%) were willing to take at least a small role in advocacy efforts. CONCLUSIONS: Most pediatricians reported feeling ineffective in their ability to treat obesity. Some practice-based barriers were specifically associated with low self-efficacy. However, pediatricians welcomed multiple clinical resources for obesity management and expressed willingness to advocate for policy change. Practice-based tool kits and efforts to engage willing participants in advocacy may help pediatricians combat this epidemic.

Does group A beta-hemolytic streptococcal infection increase risk for behavioral and neuropsychiatric symptoms in children?

OBJECTIVE: To determine whether group A beta-hemolytic streptococcal infections increase the risk of developing symptoms characteristic of the diagnosis pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections (PANDAS). DESIGN: Prospective cohort study. METHODS: Children (N = 814) aged 4 to 11 years seen for sore throat or well-child care in a large pediatric practice in Rochester, NY, were enrolled from October 2001 to June 2002 (group A beta-hemolytic streptococcal [GAS] infected, n = 411; GAS uninfected, n = 403, of whom 207 had a sore throat of presumed viral etiology and 196 were well children). Symptomatic children with GAS infection (n = 399) were treated with antibiotics. At baseline and 2 and 12 weeks following baseline, all parents completed a 20-item questionnaire about the presence/absence of recent PANDAS symptoms in their children, and capable children answered 10 items about worries, obsessions, and compulsions. The relative risk of developing a "mild PANDAS variant" (> or = 2 new PANDAS symptoms) by illness type (GAS positive, presumed viral, or well child) and by parent and child report was determined and adjusted for potential covariates. RESULTS: By parent report, ill children more frequently manifested several PANDAS symptoms at baseline than well children. However, neither new symptoms nor the risk of developing a mild PANDAS variant developed during the subsequent 12 weeks more commonly in children with GAS infection than in those with presumed viral illness or in well children by parent or child report. CONCLUSIONS: Ill children with GAS infection, treated for their GAS infection, were not at increased risk for developing PANDAS symptoms or a mild PANDAS variant compared with children with presumed viral illness or well children. The role of antibiotics in the prevention or treatment of PANDAS as well as the investigation of PANDAS in the asymptomatic, infectious host deserves future research.

Body mass index charts: useful yet underused.

OBJECTIVES: To determine how frequently pediatricians use body mass index (BMI) and whether pediatricians are more likely to regard a child as "too fat" and manifest greater concern about health sequelae when presented with BMI versus height and weight charting. STUDY DESIGN: North Carolina Pediatrics Society members completed a self-administered, quasi-experimental mail survey, using two different case vignette versions. They were given a clinical vignette but systematically received either the same hypothetical overweight child's height and weight data, percentile, and charts (Ht and Wt Group) or her BMI, percentile, and chart (BMI Group). They rated levels of fatness and concern by using Likert scales and the frequency of use of methods to determine overweight. RESULTS: Adjusted response rate was 71% (N = 356). The BMI Group rated the hypothetical child with a higher mean on a scale of fatness (P < .0001) and reported higher levels of concern about all consequences (all P values < or = .01) than those in the Ht and Wt Group. Only 11% of respondents reported "always," and 31% reported "never," using BMI. CONCLUSIONS: BMI charting prompted greater recognition of a weight problem than height and weight charting, yet BMI is inconsistently used. Interventions to help pediatricians adopt this tool may be warranted.
