Evaluation of pulmonary function and polysomnography in obese children and adolescents

Obese adults have an increased prevalence of pulmonary disorders. Although childhood obesity is a common problem, few studies have evaluated the pulmonary complications of obesity in the pediatric population. We, therefore, performed pulmonary function tests (PFTs), polysomnography, and multiple sleep latency tests (MSLTs) in 22 obese children and adolescents [mean age, 10 ± 5 (SD) years; 73% female; 184 ± 36% ideal body weight], none of whom presented because of sleep or respiratory complaints. PFTs were normal in all but two subjects. Ten (46%) subjects had abnormal polysomnograms. There was a positive correlation between the degree of obesity and the apnea index (r = 0.47, P < 0.05), and an inverse correlation between the degree of obesity and the S2O2 nadir (r = −0.60, P < 0.01). The degree of sleepiness on MSLT correlated with the degree of obesity (r = −0.50, P < 0.05). We conclude that obese children and adolescents have a high prevalence of sleep‐disordered breathing, although in many cases it is mild. Obstructive sleep apnea syndrome (OSAS) improved following tonsillectomy and adenoidectomy. We recommend that pediatricians have a high index of suspicion for OSAS when evaluating obese patients, and that polysomnography be considered for these patients. Pediatr Pulmonol. 1996; 21:176–183.

Secondary sexual characteristics in boys: data from the Pediatric Research in Office Settings Network.

BACKGROUND: Data from racially and ethnically diverse US boys are needed to determine ages of onset of secondary sexual characteristics and examine secular trends. Current international studies suggest earlier puberty in boys than previous studies, following recent trend in girls. METHODS: Two hundred and twelve practitioners collected Tanner stage and testicular volume data on 4131 boys seen for well-child care in 144 pediatric offices across the United States. Data were analyzed for prevalence and mean ages of onset of sexual maturity markers. RESULTS: Mean ages for onset of Tanner 2 genital development for non-Hispanic white, African American, and Hispanic boys were 10.14, 9.14, and 10.04 years and for stage 2 pubic hair, 11.47, 10.25, and 11.43 years respectively. Mean years for achieving testicular volumes of ≥3 mL were 9.95 for white, 9.71 for African American, and 9.63 for Hispanic boys; and for ≥4 mL were 11.46, 11.75, and 11.29 respectively. African American boys showed earlier (P < .0001) mean ages for stage 2 to 4 genital development and stage 2 to 4 pubic hair than white and Hispanic boys. No statistical differences were observed between white and Hispanic boys. CONCLUSIONS: Observed mean ages of beginning genital and pubic hair growth and early testicular volumes were 6 months to 2 years earlier than in past studies, depending on the characteristic and race/ethnicity. The causes and public health implications of this apparent shift in US boys to a lower age of onset for the development of secondary sexual characteristics in US boys needs further exploration.

Improving the management of family psychosocial problems at low-income children's well-child care visits: the WE CARE Project.

OBJECTIVE. Our goal was to evaluate the feasibility and impact of an intervention on the management of family psychosocial topics at well-child care visits at a medical home for low-income children. PATIENTS AND METHODS. A randomized, controlled trial of a 10-item self-report psychosocial screening instrument was conducted at an urban hospital-based pediatric clinic. Pediatric residents and parents were randomly assigned to either the intervention or control group. During a 12-week period, parents of children aged 2 months to 10 years presenting for a well-child care visit were enrolled. The intervention components included provider training, administration of the family psychosocial screening tool to parents before the visit, and provider access to a resource book that contained community resources. Parent outcomes were obtained from postvisit and 1-month interviews, and from medical chart review. Provider outcomes were obtained from a self-administered questionnaire collected after the study. RESULTS. Two hundred parents and 45 residents were enrolled. Compared with the control group, parents in the intervention group discussed a significantly greater number of family psychosocial topics (2.9 vs 1.8) with their resident provider and had fewer unmet desires for discussion (0.46 vs 1.41). More parents in the intervention group received at least 1 referral (51.0% vs 11.6%), most often for employment (21.9%), graduate equivalent degree programs (15.3%), and smoking-cessation classes (14.6%). After controlling for child age, Medicaid status, race, educational status, and food stamps, intervention parents at 1 month had greater odds of having contacted a community resource. The majority of residents in the intervention group reported that the survey instrument did not slow the visit; 54% reported that it added <2 minutes to the visit. CONCLUSIONS. Brief family psychosocial screening is feasible in pediatric practice. Screening and provider training may lead to greater discussion of topics and contact of community family support resources by parents.

Pediatric Residents' Clinical and Educational Experiences With End-of-Life Care

OBJECTIVE. The objective of this study was to document the frequency of pediatric resident experiences with end-of-life care for children and the educational context for these experiences, as well as to determine whether residents deem their preparatory training adequate. METHODS. An Internet-based survey was distributed to all categorical pediatric residents at the Johns Hopkins Childrens Center. Survey items asked residents to (1) quantify their experiences with specific responsibilities associated with the death of a pediatric patient, (2) identify their educational experiences, and (3) respond to Likert scale statements of, “I feel adequately trained to… .” The responsibilities were discussion of withdrawal/limitation of life-sustaining therapy, symptom management, declaration of death, discussion of autopsy, completion of a death certificate, seeking self-support, and follow-up with families. RESULTS. Forty (50%) of 80 residents completed the survey. Residents had been present for a mean (± SD) of 4.7 (± 3.0) patient deaths. More than 50% of residents had participated in discussions of withdrawal/limitation of life-sustaining therapy, symptom management, completing a death certificate, and seeking personal support; however, <50% of residents had been taught how to hold discussions of withdrawal/limitation of life-sustaining therapy, declare death, discuss autopsy, complete a death certificate, and have follow-up with families. Residents did not feel adequately trained in any of these areas. CONCLUSION. Pediatric residents have limited experience with pediatric end-of-life care and highly varied educational experiences and do not feel adequately trained to fulfill the responsibilities associated with providing end-of-life care for children. Overall, this perception does not improve with increased level of training. This study identifies several target areas for curricular intervention that may ultimately improve the end-of-life experience for our pediatric patients and their families and the young physicians who care for them.

Parents’ Healthy Weight Perceptions and Preferences Regarding Obesity Counseling in Preschoolers: Pediatricians Matter

Objective: To compare parental report of child body image with perceived healthy weight body image in preschoolers and describe weight-counseling preferences. Methods: Parents seeking well-child care were interviewed and asked to select images resembling: (a) their own child’s current weight, (b) a healthy weight preschooler, and (c) friend and family report of a healthy weight preschooler. Those indicating that their overweight or obese child resembled a healthy weight image were considered to misclassify child weight. Logistic regression was used to identify predictors of misclassification and card-sorting exercises explored weight-counseling preferences. Results: Of the 150 preschoolers in our sample, 32.7% (n = 49) were overweight or obese with misclassification occurring in 71.4% of parents (n = 35). Absence of pediatrician comment on child weight strongly predicted misclassification (odds ratio, 12.3; 95% confidence interval, 1.74-87.2). Pediatricians were highly valued weight advisors. Conclusions: Weight-focused advice from pediatricians matters to parents and may promote parental identification of early childhood weight risks.

No difference in iron status between children with low and moderate lead exposure

We compared the iron status between children 11 to 33 months old with confirmed blood lead levels of 20 to 44 microg/dL and demographically similar children with blood lead levels of <10 microg/dL. There were no differences. Laboratory investigation or empirical treatment for iron deficiency is not justified on the basis of moderately elevated blood lead levels alone.

Timing of Puberty in Overweight Versus Obese Boys

BACKGROUND AND OBJECTIVE: Studies of the relationship of weight status with timing of puberty in boys have been mixed. This study examined whether overweight and obesity are associated with differences in the timing of puberty in US boys. METHODS: We reanalyzed recent community-based pubertal data from the American Academy of Pediatrics’ Pediatric Research in Office Settings study in which trained clinicians assessed boys 6 to 16 years for height, weight, Tanner stages, testicular volume (TV), and other pubertal variables. We classified children based on BMI as normal weight, overweight, or obese and compared median age at a given Tanner stage or greater by weight class using probit and ordinal probit models and a Bayesian approach. RESULTS: Half of boys (49.9%, n = 1931) were white, 25.8% (n = 1000) were African American, and 24.3% (n = 941) were Hispanic. For genital development in white and African American boys across a variety of Tanner stages, we found earlier puberty in overweight compared with normal weight boys, and later puberty in obese compared with overweight, but no significant differences for Hispanics. For TV (≥3 mL or ≥4 mL), our findings support earlier puberty for overweight compared with normal weight white boys. CONCLUSIONS: In a large, racially diverse, community-based sample of US boys, we found evidence of earlier puberty for overweight compared with normal or obese, and later puberty for obese boys compared with normal and overweight boys. Additional studies are needed to understand the possible relationships among race/ethnicity, gender, BMI, and the timing of pubertal development.

Comparing Patients Seen in Pediatric Resident Continuity Clinics and National Ambulatory Medical Care Survey Practices: A Study From the Continuity Research Network

OBJECTIVES. The goal was to compare visit data from Continuity Research Network practices with data for a nationally representative sample of pediatric visits in practice settings from the National Ambulatory Medical Care Survey. METHODS. A cross-sectional study comparing data for Continuity Research Network practice visits during a 1-week period in 2002 with data from the 2000 National Ambulatory Medical Care Survey was performed. Continuity Research Network and National Ambulatory Medical Care Survey data were derived from 30 patient visits per practice site for patients <22 years of age, with the primary care providers being residents and practicing pediatricians, respectively. RESULTS. Eighteen Continuity Research Network practices reported on 540 visits, compared with 32 National Ambulatory Medical Care Survey physicians reporting on 792 visits. Continuity Research Network patients were more likely to be black non-Hispanic or Hispanic/Latino and to have public insurance. The top 5 reasons for visits were the same for Continuity Research Network and National Ambulatory Medical Care Survey visits, although the orders varied slightly. These 5 reasons accounted for 58% of Continuity Research Network visits and 49% of National Ambulatory Medical Care Survey visits. Continuity Research Network visits were more likely to result in patient instructions to return at a specific time (78% vs 52%). CONCLUSIONS. Residents in Continuity Research Network practices provide care to more underserved patients but evaluate problems that are similar to those observed in office practices; the Continuity Research Network practices thus provide important training experiences for residents who will serve both minority and nonminority children.
