This Policy Statement was retired July 2017.

More than 20% of children and adolescents have mental health problems. Health care professionals for children and adolescents must educate key stakeholders about the extent of these problems and work together with them to increase access to mental health resources. School-based programs offer the promise of improving access to diagnosis of and treatment for the mental health problems of children and adolescents. Pediatric health care professionals, educators, and mental health specialists should work in collaboration to develop and implement effective school-based mental health services.

Background. A history of loss of consciousness (LOC) is frequently used as an indication for cranial computed tomography (CT) in the emergency department (ED) evaluation of children with blunt head trauma.

Objective. We sought to determine whether an isolated LOC and/or amnesia is predictive of traumatic brain injury (TBI) in children with blunt head trauma.

Methods. We prospectively enrolled children <18 years old presenting to a level I trauma center ED between July 1998 and September 2001 with blunt head trauma. We evaluated the association of LOC and/or amnesia with 1) TBI identified on CT and 2) TBI requiring acute intervention. We defined the latter by a neurosurgical procedure, antiepileptic medication for >1 week, persistent neurologic deficits, or hospitalization for ≥2 nights. We then investigated the association of LOC and/or amnesia with TBI in those patients without other symptoms or signs of TBI (“isolated” LOC and/or amnesia).

Results. Of eligible children, 2043 (77%) were enrolled, 1271 (62%) of whom underwent CT; 1159 (91%) of these 1271 had their LOC and/or amnesia status known. A total of 801 (39%) of the 2043 enrolled children had a documented history of LOC and/or amnesia. Of the 745 with documented LOC and/or amnesia who underwent CT, 70 (9.4%; 95% confidence interval [CI]: 7.4%, 11.7%) had TBI identified on CT versus 11 of 414 (2.7%; 95% CI: 1.3%, 4.7%) without LOC and/or amnesia (difference: 6.7%; 95% CI: 4.1%, 9.3%). Of the 801 children known to have had LOC and/or amnesia (regardless of whether they underwent CT), 77 (9.6%; 95% CI: 7.7%, 11.9%) had TBI requiring acute intervention versus 11 of 1115 (1%; 95% CI: 0.5%, 1.8%) of those without LOC and/or amnesia (difference: 8.6%; 95% CI: 6.5%, 10.7%). For those with an isolated LOC and/or amnesia without other signs or symptoms of TBI, however, 0 of 142 (95% CI: 0%, 2.1%) had TBI identified on CT, and 0 of 164 (95% CI: 0%,1.8%) had TBI requiring acute intervention.

Conclusions. Isolated LOC and/or amnesia, defined by the absence of other clinical findings suggestive of TBI, are not predictive of either TBI on CT or TBI requiring acute intervention. Elimination of an isolated LOC and/or amnesia as an indication for CT may decrease unnecessary CT use in those patients without an appreciable risk of TBI.
Epidemiology of a Tuberculosis Outbreak in a Rural Missouri High School
Authors: Phillips Lynelle , Carlile John , Smith Diane
Published: August 2004

Objectives. 1) Demonstrate the importance of maintaining a tuberculosis (TB) control program even in low-incidence areas by studying a TB-contact investigation of a highly infectious high school student in rural Missouri, and 2) discuss factors that perpetuated or contained this school-based outbreak.

Methods. A case review of the index patient, a 15-year-old high school student, established estimates of his level and duration of infectiousness. Contact investigations of his household (n = 5), high school (n = 781), and school bus (n = 67) were administered according to guidelines established by the Centers for Disease Control and Prevention. High school students were stratified further based on classroom exposure, and relative risks were calculated for each risk group.

Results. The case review revealed that the index patient had evidence of a pulmonary cavity on chest radiograph 6 months before his TB diagnosis. Of the 5 household contacts, all were infected and 3 (60%) had developed active TB disease. Of the 781 high school students sought for TB screening, 559 (72%) completed testing, and 58 (10%) were PPD-positive. Sixty-seven bus riders were sought for testing and 7 (19%) were purified protein derivative (PPD)-positive, with 1 bus rider subsequently diagnosed with active disease.

Risks were calculated based on classroom and bus exposure to the patient. The relative risks for a positive PPD were 3.2 for attending any class with the patient (n = 25), 4.2 for classes with less ventilation (n = 21), and 5.7 for ≥3 classes (n = 7) with the patient. A total of 62 students started treatment for latent TB infection, and 49 have completed it. Forty-two of these students received directly observed therapy through the local public health agency and the high school.

Conclusion. This investigation demonstrated widespread adult-type transmission from a pediatric TB case with a 6-month delay in diagnosis. Several actions contributed to the success of this investigation, including rapidly mobilizing the public health system, centralizing follow-up, and on-site testing and treatment with directly observed therapy. Pediatricians need to maintain awareness of TB and risk factors in children, even in low-incidence areas. Prompt diagnosis would have reduced the severity of illness in the patient and potentially prevented widespread school-based transmission. Public health authorities must maintain an infrastructure to respond to large TB outbreaks.
During Toilet Training, Constipation Occurs Before Stool Toileting Refusal
Authors: Blum Nathan J. , Taubman Bruce , Nemeth Nicole
Published: August 2004

Background. Previous studies demonstrated that constipation and painful defecation are associated with stool toileting refusal (STR), but whether they are the result of STR or occur before this behavior is not known.

Objective. To determine whether constipation and painful defecation occur as a result of STR or occur before STR.

Methods. Three hundred eighty children between 17 and 19 months of age participated in a prospective longitudinal study of toilet training. Children were monitored with telephone interviews every 2 to 3 months until the completion of daytime toilet training. Information obtained in follow-up interviews included parents' reports on the presence and frequency of hard bowel movements, painful defecation, and child toilet training behaviors. Children were defined as completing daytime toilet training when they were experiencing <4 urine accidents per week and ≤2 episodes of fecal soiling per month. Children were defined as having frequent hard bowel movements if the parents reported a hard bowel movement approximately once per week in ≥2 follow-up telephone interviews or more than once per week in 1 follow-up telephone interview.

Results. The mean age at the completion of daytime toilet training was 36.8 ± 6.1 months (range: 22–54 months). Ninety-three children (24.4%) developed STR. Parents of children who developed STR, in comparison with the rest of the sample, were more likely to report that the child had experienced hard bowel movements (67.7% vs 50.9%), frequent hard bowel movements (29.0% vs 14.3%), and painful defecation (41.9% vs 27.9%). Of the children who experienced both STR and hard bowel movements, 93.4% demonstrated constipation before the onset of STR. In that group, parents reported hard bowel movements at almost one-half of all follow-up telephone interviews before the onset of STR. Of the children who experienced both STR and painful defecation, 74.4% experienced the first episode of painful defecation before the onset of STR. Children with frequent hard bowel movements demonstrated a longer duration of STR (9.0 ± 6.5 vs 4.8 ± 3.0 months).

Conclusions. When hard bowel movements or painful defecation is associated with STR, the first episode of constipation usually occurs before the STR. The fact that hard bowel movements frequently occur before the onset of STR suggests that for many of these children constipation is a chronic problem that is not being treated effectively. Therefore, hard bowel movements and painful defecation are factors that potentially contribute to the STR and for the majority of children are not caused solely by the STR behavior. Additional studies are needed to determine whether earlier and more effective treatment of constipation could decrease the incidence of STR.

Published: August 2004

Objectives. To determine the relationships between maternal depressive symptoms and the use of infant health services, parenting practices, and injury-prevention measures.

Methods. A prospective, community-based survey of women attending Philadelphia public health centers between February 2000 and November 2001 was conducted. Women were surveyed at 3 time points before and after parturition. Depressive symptoms were determined with the Center for Epidemiologic Studies Depression Scale at each time point. We studied 6 outcomes, clustered into 3 categories: 1) infant health service use (adequate well-child care and ever being hospitalized); 2) parenting practices (breastfeeding for ≥1 month and use of corporal punishment); and 3) injury-prevention measures (having a smoke alarm and using the back sleep position).

Results. The sample consisted of 774 largely single (74%), uninsured (63%), African American (65%) women, with a mean age of 24 ± 6 years and a mean annual income of $8063. Forty-eight percent of women had depressive symptoms at 1 or 2 time points (ever symptoms) and 12% had depressive symptoms at all points (persistent symptoms). Compared with women who never had depressive symptoms (without symptoms), women with persistent symptoms were nearly 3 times as likely to have their child ever hospitalized (adjusted odds ratio: 2.89; 95% confidence interval: 1.61–5.07) and twice as likely to use corporal punishment (adjusted odds ratio: 1.90; 95% confidence interval: 1.08–3.34). Mothers with persistent depressive symptoms were nearly three-quarters less likely to have smoke alarms in their homes (adjusted odds ratio: 0.28; 95% confidence interval: 0.11–0.70) and one-half as likely to use the back sleep position (adjusted odds ratio: 0.56; 95% confidence interval: 0.35–0.91), compared with women without symptoms. There was no association between maternal depressive symptoms and infant receipt of well-child care or the likelihood of breastfeeding for ≥1 month.

Conclusions. Maternal depressive symptoms persisting from the prepartum to postpartum periods were associated with increased risks of infant hospitalization and use of corporal punishment and with lower likelihood of having a smoke alarm and using the back sleep position. Additional efforts are needed to identify and evaluate mothers with depressive symptoms to improve the health and safety of young infants.

Published: August 2004

Objective. Psychiatric manifestations of pediatric human immunodeficiency virus (HIV) infection have been described. However, data on severe sequelae requiring hospitalization among this population have not been reported.

Methods. The Pediatric Acquired Immunodeficiency Syndrome (AIDS) Clinical Trials Group (PACTG) 219C is a prospective cohort study designed to examine long-term outcomes among HIV-infected children and HIV-uninfected infants born to HIV-infected women. Children with HIV infection who have enrolled in PACTG 219C are examined quarterly, with collection of clinical and laboratory data. Hospitalizations and diagnoses for all participants between September 2000 (when enrollment into PACTG 219C was started) and December 2002 were reviewed.

Results. Among 1808 HIV-infected participants who were <15 years of age at the last visit date, 25 children had been hospitalized for psychiatric manifestations, 8 before enrollment into PACTG 219C. Seventeen children were hospitalized during 2757 person-years of follow-up monitoring after entry into PACTG 219C, which represents an incidence of 6.17 cases per 1000 person-years (95% confidence interval: 3.59–9.87 cases per 1000 person-years). This was significantly higher than the incidence of 1.70 cases per 1000 person-years (95% confidence interval: 1.67–1.72 cases per 1000 person-years) in the general pediatric population <15 years of age, as reported in the 2000 National Hospital Discharge Survey, yielding a relative rate of 3.62 (95% confidence interval: 2.11–5.80). A total of 32 HIV-infected children, regardless of age, were hospitalized because of psychiatric illnesses. The majority of patients were admitted because of depression (n = 16) or behavioral disorders (n = 8). Fifteen (47%) underwent multiple psychiatric hospitalizations. The median age at the first psychiatric hospitalization was 11 years (range: 4–17 years); all patients had been perinatally infected. Knowledge of HIV seropositivity status and having experienced a significant life event were both significantly associated with an increased risk of psychiatric hospitalization (hazard ratios of 6.13 and 3.04, respectively). No psychiatric hospitalizations were observed among the 1021 HIV-uninfected members of the cohort.

Conclusions. Children with HIV/AIDS are at increased risk for psychiatric hospitalizations during childhood and early adolescence, compared with the general pediatric population. Knowledge of HIV seropositivity status and recent significant life events were significantly associated with increased risks of admission in this population.
Early Extubation and Nasal Continuous Positive Airway Pressure After Surfactant Treatment for Respiratory Distress Syndrome Among Preterm Infants <30 Weeks’ Gestation
Authors: Dani Carlo , Bertini Giovanna , Pezzati Marco , Cecchi Alessandra , Caviglioli Cosimo , Rubaltelli Firmino F.
Published: August 2004

Objective. To test the hypothesis that preterm infants with infant respiratory distress syndrome who are treated with nasal continuous positive airway pressure (NCPAP) and surfactant administration followed by immediate extubation and NCPAP application (SURF-NCPAP group) demonstrate less need for mechanical ventilation (MV), compared with infants who receive MV after surfactant administration (SURF-MV group).

Methods. A prospective randomized study was conducted, in which infants <30 weeks’ gestation were randomized to the SURF-NCPAP group or the SURF-MV group.

Results. At 7 days of life, no patient in the SURF-NCPAP group but 6 patients (43%) in the SURF-MV group still were undergoing MV. The duration of oxygen therapy, NCPAP, and MV, the need for a second dose of surfactant, and the length of stay in the intensive care unit were significantly greater in the SURF-MV group.

Conclusions. The immediate reinstitution of NCPAP after surfactant administration for infants with infant respiratory distress syndrome is safe and beneficial, as indicated by the lesser need for MV and the briefer requirement for respiratory supports, compared with the institution of MV after surfactant treatment. Moreover, this strategy contributed to reducing the need for surfactant treatment and reducing the time and costs involved in keeping the infants in the neonatal intensive care unit.
Plasma C-Reactive Protein Levels Among Children With Sleep-Disordered Breathing
Authors: Tauman Riva , Ivanenko Anna , O'Brien Louise M. , Gozal David
Published: August 2004

Introduction. Levels of C-reactive protein (CRP), an important serum marker of inflammation with major implications for cardiovascular morbidity and atherogenesis, are elevated among adult patients with sleep-disordered breathing (SDB). We hypothesized that elevated CRP plasma levels would also be present among children with SDB.

Methods. Eighty-one children (mean age: 9.3 ± 3.7 years) underwent polysomnographic evaluations. Samples for plasma CRP level and lipid profile determinations were drawn the next morning.

Results. Because plasma CRP levels were not normally distributed in this cohort, logarithmic transformation was applied. Log plasma CRP levels were significantly higher in the SDB group (obstructive apnea/hypopnea index [AHI] of ≥5), compared with the mild SDB group (AHI of ≥1 and <5) and the control group (AHI of <1). Significant positive correlations were found between log CRP levels and AHI (r = .53) and arousal index (r = .28), whereas an inverse correlation was found between the lowest nocturnal arterial oxygen saturation and log CRP levels (r = −.47). These correlations persisted after exclusion of outliers. Moreover, 94% of the children with elevated log CRP levels reported excessive daytime sleepiness and/or learning problems, compared with 62% of the children with normal log CRP levels.

Conclusions. Plasma CRP levels were increased among some children with SDB and were correlated with AHI, arterial oxygen saturation nadir, and arousal index measures. These changes were particularly prominent among children who were sleepy or presented with neurobehavioral complaints. The intermittent hypoxemia and sleep fragmentation of SDB may underlie inflammatory responses, the magnitude of which may ultimately lead to the cardiovascular, cognitive, and behavioral morbidities of SDB.
A Brief Screening Questionnaire for Infant Sleep Problems: Validation and Findings for an Internet Sample
Authors: Sadeh Avi
Published: August 2004

Objective. To develop and validate (using subjective and objective methods) a brief infant sleep questionnaire (BISQ) that would be appropriate for screening in pediatric settings.

Design. Two studies were performed to assess the properties of the BISQ. Study I compared BISQ measures with sleep diary measures and objective actigraphic sleep measures for clinical (N = 43) and control (N = 57) groups of infants (5–29 months of age). The second study was based on an Internet survey of 1028 respondents who completed the BISQ posted on an infant sleep web site.

Results. In study I, BISQ measures were found to be correlated significantly with sleep measures derived from actigraphy and sleep diaries. BISQ measures (number of night wakings and nocturnal sleep duration) were the best predictors for distinguishing between clinical and control samples. High test-retest correlations (r > .82) were demonstrated for BISQ measures for a subsample of 26 infants. Study II provided a developmental perspective on BISQ measures. The study demonstrated that BISQ measures derived from a large Internet survey provided developmental and sleep ecology-related findings that corresponded to the existing literature findings on sleep patterns in early childhood.

Conclusions. The findings provide psychometric, clinical, and ecologic support for the use of the BISQ as a brief infant sleep screening tool for clinical and research purposes. Potential clinical cutoff scores are provided.

Published: August 2004

Background. It has been proposed that infection by group A β-hemolytic streptococci (GABHS) can trigger acute symptom exacerbations among patients with Tourette’s syndrome (TS) or obsessive-compulsive disorder (OCD), via autoimmune mechanisms.

Objective. To examine the temporal relationship between newly acquired GABHS infections (and other immunologic indices) and acute exacerbations of tics and obsessive-compulsive symptoms.

Methods. Pediatric patients (7–17 years of age) with TS and/or OCD (N = 47) and healthy control subjects (N = 19) were prospectively monitored for newly acquired GABHS infections, nonspecific markers of acute inflammatory responses, and D8/17-reactive cells (a marker of rheumatic fever). Objective monthly ratings of tic and obsessive-compulsive symptom severity were used to determine the timing of symptom exacerbations.

Results. The overall rate of acute exacerbations of neuropsychiatric symptoms was 0.56 exacerbations per patient per year. The average rate of new GABHS infections, using a stringent definition, was 0.42 infections per subject per year among patients, compared with 0.28 infections per subject per year for control subjects. The association between symptom exacerbations and new GABHS infections among patients was no greater than that expected on the basis of chance. At baseline, patients demonstrated significantly higher levels of D8/17-reactive cells and neopterin, compared with control subjects, but there was no consistent pattern of change when exacerbation time points were compared with baseline or follow-up time points.

Conclusions. The results suggest no clear relationship between new GABHS infections and symptom exacerbations in an unselected group of patients with TS and/or OCD.
Heat Stress and Sudden Infant Death Syndrome Incidence: A United States Population Epidemiologic Study
Authors: Scheers-Masters Joshua R. , Schootman Mario , Thach Bradley T.
Published: August 2004

Objectives. To determine the role of heat stress in sudden infant death syndrome (SIDS) by examining the SIDS rates during periods of extreme environmental temperatures in a period when most infants were placed prone for sleep.

Design. A retrospective study of SIDS rates and mortality rates attributable to excessive environmental heat in relationship to climatologic temperature was performed. Data were collected for each of 454 counties in 4 states (Arkansas, Georgia, Kansas, and Missouri) from May 1 to September 30, 1980, and were then summed to yield the mortality rates for each 5°F (2.8°C) temperature range.

Results. χ2 analyses revealed significant relationships for heat-related mortality rates and both the maximal daily temperature and mean daily temperature but demonstrated no such relationships for SIDS rates. No association between SIDS rates and heat-related mortality rates was found with Spearman’s ranked correlation, for either the maximal daily temperature or the mean daily temperature.

Conclusions. On the basis of our findings of no significant association between SIDS and either measure of temperature during periods of high heat stress-related death rates, it seems unlikely that the heat stress associated with the combination of prone sleep positions and elevated environmental temperatures has a significant role in the development of SIDS.
Shifts in Percentiles of Growth During Early Childhood: Analysis of Longitudinal Data From the California Child Health and Development Study
Authors: Mei Zuguo , Grummer-Strawn Laurence M. , Thompson Diane , Dietz William H.
Published: August 2004

Objective. To document growth-velocity changes across major percentiles during the preschool years.

Design. Analyses of longitudinal data using height-for-age, weight-for-age, weight-for-height, and body mass index (BMI)-for-age percentiles were performed to examine crossing of major percentiles of the Centers for Disease Control and Prevention 2000 growth charts. The 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles were defined as the major percentiles.

Setting. Data from the California Child Health and Development Study were used.

Subjects. A total of 10 844 children up to 60 months of age, with 44 296 height and weight measurements, were included in our final analysis.

Results. For height-for-age, 32% of children between birth and 6 months of age, 13% to 15% of children between 6 and 24 months of age, and 2% to 10% of children between 24 and 60 months of age crossed 2 major percentiles. For weight-for-age, 39% of children between birth and 6 months of age, 6% to 15% of children between 6 and 24 months of age, and 1% to 5% of children between 24 and 60 months of age crossed 2 major percentiles. In contrast, for weight-for-height, 62% of children between birth and 6 months of age, 20% to 27% of children between 6 and 24 months of age, and 6% to 15% of children between 24 to 60 months of age crossed 2 major percentiles. Similar to the pattern observed for weight-for-height, 8% to 15% of children between 24 and 60 months of age crossed 2 major BMI-for-age percentiles. During the preschool years, weight-for-height had the highest percentages of children who crossed 2 major percentiles, and weight-for-age had the lowest percentages of children who crossed 2 major percentiles among these 3 indices.

Conclusions. Shifts in growth rates were very common for children from birth to 6 months of age, somewhat less common for children 6 to 24 months of age, and least common for children 24 to 60 months of age. Shifts in weight-for-height occurred more frequently than did other growth changes. Pediatricians must consider the prevalence of growth rate shifts during infancy and early childhood before they counsel parents regarding growth or refer children for additional evaluations of growth.
Measurement of Interleukin 8 in Combination With C-Reactive Protein Reduced Unnecessary Antibiotic Therapy in Newborn Infants: A Multicenter, Randomized, Controlled Trial
Authors: Franz Axel R. , Bauer Karl , Schalk Andreas , Garland Suzanne M. , Bowman Ellen D. , Rex Kerstin , Nyholm Calle , Norman Mikael , Bougatef Adel , Kron Martina , Mihatsch Walter Andreas , Pohlandt Frank ,   for the International IL-8 Study Group
Published: August 2004

Objective. Neonatal bacterial infections carry a high mortality when diagnosed late. Early diagnosis is difficult because initial clinical signs are nonspecific. Consequently, physicians frequently prescribe antibiotic treatment to newborn infants for fear of missing a life-threatening infection. This study was designed to test the hypotheses that a diagnostic algorithm that includes measurements of interleukin 8 (IL-8) and C-reactive protein (CRP) 1) reduces antibiotic therapy and 2) does not result in more initially missed infections compared with standard management that does not include an IL-8 measurement.

Methods. Term and preterm infants who were <72 hours of age and had clinical signs or obstetric risk factors suggesting neonatal bacterial infection but stable enough to wait for results of diagnostic tests were enrolled into the study. A total of 1291 infants were randomly assigned to receive antibiotic therapy according to the guidelines of each center (standard group) or to receive antibiotic therapy when IL-8 was >70 pg/mL and/or CRP was >10 mg/L (IL-8 group). The primary outcome variables were 1) the number of infants treated with antibiotics and 2) the number of infants with infections missed at the initial evaluation.

Results. In the IL-8 group, fewer infants received antibiotic therapy than in the standard group (36.1% [237 of 656] vs 49.6% [315 of 635]). In the IL-8 group, 24 (14.5%) of 165 infants with infection were not detected at the initial evaluation, compared with 28 (17.3%) of 162 in the standard group.

Conclusions. The number of newborn infants who received postnatal antibiotic therapy can be reduced with a diagnostic algorithm that includes measurements of IL-8 and CRP. This diagnostic strategy seemed to be safe.
Overweight Children and Adolescents: A Risk Group for Iron Deficiency
Authors: Nead Karen G. , Halterman Jill S. , Kaczorowski Jeffrey M. , Auinger Peggy , Weitzman Michael
Published: August 2004

Background. The prevalence of obesity has increased at an epidemic rate, and obesity has become one of the most common health concerns in the United States. A few small studies have noted a possible association between iron deficiency and obesity.

Objective. To investigate the association between weight status, as measured by body mass index (BMI), and iron deficiency in a nationally representative sample of children and adolescents.

Design. National Health and Nutrition Examination Survey III (1988–1994) provides cross-sectional data on children 2 to 16 years of age. Recorded measures of iron status included transferrin saturation, free erythrocyte protoporphyrin levels, and serum ferritin levels. Children were considered iron-deficient if any 2 of these values were abnormal for age and gender. With the use of age- and gender-specific BMI percentiles, at risk for overweight was defined as a BMI of ≥85th percentile and <95th percentile, and overweight was defined as a BMI of ≥95th percentile. The prevalence of iron deficiency was compared across weight groups. Logistic regression was used to estimate the association between iron status and overweight, controlling for age, gender, ethnicity, poverty status, and parental education level.

Results. In this sample of 9698 children, 13.7% were at risk for overweight and 10.2% were overweight. Iron deficiency was most prevalent among 12- to 16-year-old subjects (4.7%), followed by 2- to 5-year-old subjects (2.3%) and then 6- to 11-year-old subjects (1.8%). Overweight 2- to 5-year-old subjects (6.2%) and overweight 12- to 16-year-old subjects (9.1%) demonstrated the highest prevalences of iron deficiency. Overall, the prevalence of iron deficiency increased as BMI increased from normal weight to at risk for overweight to overweight (2.1%, 5.3%, and 5.5%, respectively), and iron deficiency was particularly common among adolescents (3.5%, 7.2%, and 9.1%, respectively). In a multivariate regression analysis, children who were at risk for overweight and children who were overweight were approximately twice as likely to be iron-deficient (odds ratio: 2.0; 95% confidence interval: 1.2–3.5; and odds ratio: 2.3; 95% confidence interval: 1.4–3.9; respectively) as were those who were not overweight.

Conclusions. In this national sample, overweight children demonstrated an increased prevalence of iron deficiency. Given the increasing numbers of overweight children and the known morbidities of iron deficiency, these findings suggest that guidelines for screening for iron deficiency may need to be modified to include children with elevated BMI.
Violators of a Child Passenger Safety Law
Authors: Agran Phyllis F. , Anderson Craig L. , Winn Diane G.
Published: August 2004

Background. Nonuse of child car safety seats (CSSs) remains significant; in 2000, 47% of occupant fatalities among children <5 years of age involved unrestrained children. Nonusers and part-time users of CSSs represent small proportions of the US population that have not responded to intervention efforts. Our study examined the factors contributing to nonuse or part-time use of CSSs and the effects of exposure to a class for violators of the California Child Passenger Safety (CPS) law.

Methods. Focus groups (in English and Spanish) were conducted with individuals cited for violation of the law (N = 24). A thematic analysis of notes made by an observer, supplemented by audiotapes of the sessions, was conducted. In addition, a study of the effects of exposure to a violator class on knowledge and correct CSS use was conducted among violators. Certified CPS technicians conducted the classes and interviews. Subjects were parents cited as the driver with a child of 20 to 40 pounds, between 12 and 47 months of age. One hundred subjects recruited from the class were compared with 50 subjects who did not attend a class. Follow-up home interviews, with inspection of CCS use, were conducted 3 months after payment of the fine and completion of all court requirements. Fisher’s exact test was used for 2 × 2 tables, because some of the tables had small cell sizes. The Mann-Whitney rank sum test was used for child restraint use, knowledge, and correct use scales, because some of these variables were not normally distributed. Linear and logistic regression models were used to examine the effects of several variables on these parameters.

Results. Factors influencing CSS nonuse were 1) lifestyle factors, 2) transportation and trip circumstances, 3) nonparent or nondriver issues, 4) parenting style, 5) child’s behavior, and 6) perceived risks of nonuse. Violator subjects were mostly Hispanic and female, with incomes of less than $30 000 per year. Those exposed to the class (citation and education group) scored 1 point higher on a knowledge test and had 1 more item correct on a CSS use instrument than did the group not exposed to the class (citation only group). In the logistic model, the citation and education group scored higher on the 2 items that were corrected by the instructor during the class.

Conclusion. Our focus group study of CPS law violators revealed that multiple complex factors influence consistent use of a CSS. The interplay of the particular vehicle, the trip circumstances, and family/parent/child factors affected the use of a CSS at the time of parent citation. Addressing transportation issues and parenting skills in CPS programs is necessary. Among parents who had been ticketed for not restraining their children, exposure to a violator class demonstrated some benefit, compared with a fine alone. Correct CSS use improved most on items corrected by the instructor. Violator classes that include “hands-on” training show promise for improving rates of correct use of CSSs.
Evaluation of a Type 2 Diabetes Screening Protocol in an Urban Pediatric Clinic
Authors: Drobac Stephanie , Brickman Wendy , Smith Tiy , Binns Helen J.
Published: August 2004

Background. In 2000, the American Diabetes Association issued recommendations for type 2 diabetes mellitus screening among children. They recommended testing children ≥10 years of age who have a body mass index (BMI) of >85th percentile for age and at least 2 other risk factors (family history of type 2 diabetes, high-risk race/ethnicity, or evidence of insulin resistance, such as acanthosis nigricans).

Objective. To describe the application of a type 2 diabetes mellitus screening protocol in an urban pediatric clinic.

Design/Methods. Medical records for patients 10 to 18 years of age who were examined in health maintenance visits during a 13-month period were reviewed; 997 subjects were included in the analyses. Data collected included demographic features, medical history, family history, physical examination findings, dietary and physical activity counseling, and results of laboratory tests. BMI percentiles for age were determined from national references.

Results. Subjects were 50% male (median age: 13.2 years), 96% Hispanic, and 48% (n = 477) had a >85th percentile BMI (including 26% with a ≥95th percentile BMI). Of the 477 subjects, 100% were in high-risk racial/ethnic groups, 29% had a family history of diabetes, and 20% demonstrated evidence of insulin resistance; 194 (41%) met the criteria for screening. Of those who met the criteria, 38% (n = 73) had screening ordered and 65 of those subjects (89%) completed screening. Acanthosis nigricans was more common among subjects for whom screening was ordered (69%), compared with subjects who were not screened (3%). Three screened subjects exhibited impaired glucose tolerance; none had overt diabetes. Subjects for whom screening was ordered were more likely to have received counseling than were subjects not recognized as qualifying for screening (84% vs 52%).

Conclusions. At this high-risk clinical site, the American Diabetes Association type 2 diabetes screening protocol was inconsistently applied. Acanthosis nigricans was a driving factor in identification and screening. Recognition of the need for screening was associated with a higher rate of documentation of nutritional counseling. Additional evaluation of the effectiveness of screening protocols in the early identification of diabetes and the effects of screening protocols on long-term morbidity is needed.

Objective. To determine if young adolescents who report that their parents restrict viewing R-rated movies have a lower risk of trying smoking in the future.

Design. Prospective observational study. Students from 15 schools in New Hampshire and Vermont, randomly selected from all middle schools with >150 students, were surveyed in 1999. Baseline never-smokers were surveyed again by telephone 13 to 26 months later to determine smoking status.

Outcome Measure. Trying smoking during the follow-up period.

Results. The majority of the 2596 students were white, with ages ranging from 10 to 14 years. Nineteen percent reported that their parents never allowed them to view R-rated movies, 29% were allowed once in a while, and 52% were allowed sometimes or all the time. Ten percent of students tried smoking during the follow-up period. Smoking-initiation rates increased as parental restriction of R-rated movies decreased (2.9% for adolescents reporting that their parents never allowed them to view R-rated movies, 7.0% for those allowed to view them once in a while, and 14.3% for those allowed to view them sometimes or all the time). There was a strong and statistically significant effect of parental R-rated movie restriction on adolescent smoking even after controlling for sociodemographics, social influences (friend smoking, receptivity to tobacco promotions), parenting style (maternal support and control, parental disapproval of smoking), and characteristics of the adolescent (school performance, sensation seeking, rebelliousness, self-esteem). Compared with adolescents whose parents never allowed them to view R-rated movies, the adjusted relative risk for trying smoking was 1.8 (95% confidence interval [CI]: 1.1, 3.1) for those allowed to watch them once in a while and 2.8 (95% CI: 1.6, 4.7) for those allowed to watch them sometimes or all the time. The effect was especially strong among adolescents not exposed to family (parent or sibling) smoking, among whom the adjusted relative risk for smoking was 4.3 (95% CI: 1.4, 13) for those allowed to view R-rated movies once in a while and 10.0 (95% CI: 3.6, 31) for those allowed to view them sometimes or all the time.

Conclusions. Parental restriction from watching R-rated movies strongly predicts a lower risk of trying smoking in the future. The effect is largest among adolescents not exposed to family smoking. By exerting control over media choices and by not smoking themselves, parents may be able to prevent or delay smoking in their children.

Background. This study reports the epidemiologic features, survival rates, and neurologic outcomes of the largest population-based series of pediatric out-of-hospital cardiopulmonary arrest patients with prospectively collected data.

Methods. Secondary analysis of data from a prospective, interventional trial of out-of-hospital pediatric airway management conducted from 1994 to 1997 (Gausche M, Lewis RJ, Stratton SJ, et al. JAMA. 2000;283:783-790). Consecutive out-of-hospital patients from 2 large urban counties in California <12 years old or 40 kg in bodyweight who were determined by paramedics to be pulseless and apneic were included. Main outcome measures included survival to hospital discharge, patient demographics, arrest etiology, arrest rhythm, event intervals, and neurologic outcomes.

Results. In 599 patients, 601 events were studied (54% were <1 year old, 58% were male). Return of spontaneous circulation was achieved in 29%; 25% were admitted to the hospital, and 8.6% (51) survived to hospital discharge. The most prevalent etiologies were sudden infant death syndrome and trauma; these resulted in relatively higher mortality. Respiratory etiologies and submersions followed; these resulted in relatively lower mortality. Twenty-six percent of the arrests were witnessed by citizens, and an additional 8% were witnessed by rescue personnel. Witnessed arrests had a higher survival rate (16%). Thirty-one percent of patients received bystander cardiopulmonary resuscitation, which was not demonstrated to result in improved survival rates. Arrest rhythms were asystole (67%), pulseless electrical activity (24%), and ventricular fibrillation (9%); children with the latter 2 rhythms had better survival rates. One third of the survivors (16 of 51) had good neurologic outcome, none of whom received >3 doses of epinephrine or were resuscitated for >31 minutes in the emergency department.

Conclusions. The 8.6% survival rate after out-of-hospital pediatric cardiopulmonary arrest is poor. Administration of >3 doses of epinephrine or prolonged resuscitation is futile.

Objective. To describe the clinical features that distinguish accidental from abusive head injury in hospitalized children <24 months of age.

Methods. Prospective study of children <24 months of age hospitalized for head injury between August 1, 2000, and October 31, 2002. During hospitalization, children had computed tomographic scans of the brain, serial neurologic examinations, dilated ophthalmoscopic eye examinations, evaluation by a social worker, and, in some cases, a child abuse specialist.

Outcome Measures. The main outcome measure was the proportion of children in each group with retinal hemorrhages (RHs). Secondary outcome measures were the proportion of children in each group who had vitreous hemorrhage; abnormal mental status on presentation; seizures; scalp hematomas; need for anticonvulsants; and operative procedures such as subdural tap, craniotomy, ventriculostomy, tracheostomy, and gastrostomy.

Results. Eighty-seven children were prospectively enrolled. Fifteen children were classified as having abusive head injury, and 72 were classified as having accidental head injury. Five children, all in the accidental head injury group, were excluded from statistical analysis, because they did not have a dilated ophthalmoscopic examination during their hospitalization. Thus 82 children were included in the statistical analysis. There were no significant differences between the 2 groups with respect to mean age, gender, or ethnicity. RHs were more likely to be seen in children with abusive head injury (60% vs 10%) and were more likely to be bilateral (40% vs 1.5%). Pre-RHs were more likely to be seen in children with abusive head injury (30% vs 0%). Premacular RHs and RHs that extended to the periphery of the retina were also more likely to be seen in children with abusive head injury (20% vs 0% and 27% vs 0%, respectively). Of the 7 children with accidental head injury who had RHs, 6 had unilateral RHs. Children with abusive head injury were more likely to have seizures (53% vs 6%) and an abnormal mental status on initial presentation (53% vs 1%). Children with accidental head injury were more likely to have scalp hematomas (6.7% vs 49%).

Conclusions. RHs are seen more often in abusive head injury and often are bilateral and involve the preretinal layer. Children with abusive head injury were more likely to have RHs that cover the macula and extend to the periphery of the retina. Unilateral RHs can be seen in children with accidental head injury. Children with abusive head injury were more likely to present with abnormal mental status and seizures, whereas children with accidental head injury were more likely to have scalp hematomas. Such characteristics may be useful to distinguish accidental from abusive head trauma in children <24 months of age.

Objectives. Acute otitis media (OM) is the most common indication for the use of antibiotics among children. Otoscopy alone is an imprecise method for the diagnosis of OM, which may lead to inappropriate antibiotic use. We sought to determine whether tympanometry, as an adjunct to otoscopy, would significantly change physician prescribing behavior and whether physicians overprescribe antibiotics for OM, using independently graded tympanometry results as a standard.

Methods. A randomized, clinical trial was conducted among children 6 to 35 months of age who presented to a pediatric emergency department with either fever or upper respiratory infection symptoms. Children were randomized into 2 groups, in which the attending physician evaluated tympanometry results (Tymp Aware) or the attending physician was blinded to the tympanometry findings (Tymp Unaware). Tympanometry curves were graded independently by using a modified version of the Jerger scale.

Results. Of the 698 patients enrolled, tympanometry was performed successfully for 99.3%. Antibiotics were prescribed for OM for 27.9% of all patients. No statistically significant difference in antibiotic prescription rates for OM between the Tymp Aware group (28.8%) and the Tymp Unaware group (26.8%) was found. Of all patients for whom antibiotics were prescribed for OM, 14% had normal curves for both ears and 40% had some tympanographic movement bilaterally.

Conclusions. Tympanometry did not seem to change diagnoses or prescribing behavior in the group of physicians studied. Antibiotics were commonly prescribed for presumed OM in the absence of effusions documented with tympanometry.
