Cross-sectional studies in children and adults have reported a significant positive association between attention-deficit/hyperactivity disorder (ADHD) and obesity.

This controlled, prospective, follow-up study of boys with ADHD found significantly higher BMI and obesity rates in adulthood, compared with men without childhood ADHD, regardless of socioeconomic status and other lifetime mental disorders. (Read the full article)

The United States switched from whole-cell to acellular pertussis vaccines during the 1990s. Whether pertussis risk during a California outbreak differed between teenagers who previously received whole-cell or acellular pertussis vaccines early in life has not been reported.

We evaluated pertussis risk in 10 to 17 year olds at Kaiser Permanente Northern California during a recent pertussis outbreak. Those given whole-cell pertussis vaccines in childhood were more protected than those given acellular pertussis vaccines. (Read the full article)

Routine head ultrasound scans (HUSs) are frequently performed in the preoperative evaluation of the infants with congenital heart disease, and brain MRI is being increasingly used in the research setting. The utility of HUSs in this population has not yet been established.

This is the first study to prospectively evaluate the utility of routine HUSs compared with MRIs in asymptomatic newborns and young infants undergoing cardiac surgery. Our findings suggest that routine HUS is not indicated in asymptomatic term or near-term neonates undergoing surgery for CHD. (Read the full article)

Sleep patterns of adult monozygotic twins are more similar than those of dizygotic twins, showing moderate heritability and little effects of environmental influences. There have been very few genetically informative studies of sleep in preschool children and results appear inconsistent.

From previous studies, we investigated daytime and nighttime continuous sleep duration longitudinally. This is the first time that the etiologies of daytime and nighttime continuous sleep duration trajectories were studied in early childhood. (Read the full article)

Early preventive pediatric dental visits are widely recommended. However, the effectiveness of pediatric preventive dental visits in reducing the need for subsequent, more expensive oral health treatment has not been well established.

Using an econometric method that accounts for time-invariant differences between children, and thus helps mitigate selection bias, we found a positive impact of preventive dental visits on oral health. However, there is less evidence regarding the cost-effectiveness of preventive visits. (Read the full article)

There are ethnic differences in lung function, with white people generally having higher values of FVC and FEV₁ than people of South Asian origin, whereas differences in forced expiratory flows are absent or less marked. The underlying reasons are unknown.

Lung function differences were not explained by cultural, socioeconomic, or perinatal factors, nor by environmental exposures or wheezing illness. This suggests that genetic factors are responsible, and supports the use of ethnicity-specific prediction equations for children of South Asian origin. (Read the full article)

Physicians have little knowledge of health care costs and charges. Studies suggest that education and awareness of hospital finances can decrease unnecessary utilization of resources. Little is known about pediatricians’ awareness of the economics of health care delivery in the inpatient setting.

Both general pediatric attending physicians and trainees acknowledged a limited understanding of hospital finances, and they demonstrated a lack of awareness of costs, charges, and reimbursements for inpatient care. (Read the full article)

Obesity is a growing concern for Mexican-American adolescents, with both behavioral and cultural variables that are related to the increasing trend.

These results highlight a patient-centered view of the emotional and physical burden of obesity in female Mexican-American adolescents, the families’ personal struggles with weight-related conditions, and the challenge of balancing family needs with those specific to the adolescent.

Medication ingestions are increasing among children despite a number of public health interventions. The majority of these poisonings are related to prescription as opposed to over-the-counter medications.

Rising rates of poisonings in children are strongly correlated with rising use of hypoglycemics, antihyperlipidemics, β-blockers, and opioids among adults. These events are associated with considerable health care utilization, both in terms of emergency department visits and hospital admissions. (Read the full article)

Bronchiolitis is often cited as the leading cause of hospitalization for young children in the United States Previous studies reported increases in bronchiolitis hospitalizations through the 1990s. There are no recent efforts to assess national trends in bronchiolitis incidence and health care utilization.

Between 2000 and 2009, we found a significant decline in bronchiolitis hospitalizations among US children. By contrast, use of mechanical ventilation and hospital charges for bronchiolitis significantly increased over this same period. (Read the full article)

The remarkable improvement in the survival of extremely premature infants has been well documented. However, there have been few cohort studies large enough to determine the neurodevelopmental outcomes of survivors born at 22 or 23 weeks.

The proportions of unimpaired or minimally impaired were 12.0% at 22 weeks (n = 75) and 20.0% at 23 weeks (n = 245). The outcomes were inferior compared with those for infants born at 24 and 25 weeks, but were improved compared with those in previous studies. (Read the full article)

Atherosclerotic cardiovascular diseases are rooted in childhood. Vascular intima-media thickness (IMT) and elasticity are early surrogate markers of atherosclerosis. In adults, cardiorespiratory fitness is associated with enhanced arterial elasticity and decreased IMT.

Fitness was favorably associated with aortic IMT and elasticity in adolescents. The association was independent of several cardiometabolic risk factors. In fit adolescents, the increase in IMT during the preceding 6 years was smaller compared with low-fit peers. (Read the full article)

Pediatric palliative care (PC) can be beneficial to children with life-threatening conditions and their families by providing symptom management and control, sibling support, bereavement services, spiritual guidance, support in decision-making about limiting burdensome medical interventions, and advance directives.

Little is known about actual receipt of PC by dying children. This study compares characteristics of dying children by receipt of PC and highlights underserved patient groups who could be targeted to improve access. (Read the full article)

Internet, smartphones, and online social media offer new platforms for health promotion and disease management. Few studies have evaluated the use of digital technology among families receiving care in an urban pediatric primary care setting.

Caregivers in an urban pediatric primary care setting have access to and frequently use the Internet, smartphones, and online social media. These technologies may help reach a traditionally hard-to-reach population. (Read the full article)

Elevated blood pressure (BP) has long-term influence on the atherosclerotic process. The relative predictive ability of the standard BP definition endorsed by the National High Blood Pressure Education Program and the recently proposed 2 simplified definitions has not been studied.

Simplified pediatric BP tables predict risk of high adult arterial stiffness as well as the complex table does. These simple screening tools could be used for identifying pediatric subjects at risk and for intervening to improve adult cardiovascular outcomes. (Read the full article)

About one in five 2-year-olds are overweight, with potential adverse outcomes. Early feeding practices lay the foundation for food preferences and eating behavior and may contribute to future obesity risk. High-quality obesity prevention trials commencing in infancy are rare.

In this large randomized controlled trial, anticipatory guidance on the "when, what, and how" of complementary feeding was associated with increased maternal "protective" feeding practices. Differences in anthropometric indicators were in the expected direction but did not achieve statistical significance. (Read the full article)

The ideal management of children with vesicoureteral reflux (VUR) remains a source of debate. There is little evidence to support many of the current management practices for children with VUR who have had 1 or 2 urinary tract infections.

Baseline associations, including bladder and bowel dysfunction and imaging studies, from the largest randomized, controlled trial conducted to date aimed at assessing the value of antimicrobial prophylaxis in children with urinary tract infection and VUR are presented. (Read the full article)

Health care professionals face problems managing obesity and often fail to follow guidelines for its management in practice. Only a few single-country reports are available describing delivery of primary care to children with obesity.

Nearly all primary pediatric care providers from 4 European countries recognize the importance of obesity in pediatric practice, but only half use BMI clinically, and many lack the confidence and the infrastructure needed for providing care to patients with obesity. (Read the full article)

Uric acid (UA) is associated with hypertension in children, after body weight adjustment. Whether the whole spectrum of variables, such as visceral adiposity, insulin resistance, puberty, and renal function, influence the relationship between UA and blood pressure is unknown.

In a cohort of children at relatively high cardiovascular risk, the association between UA and blood pressure levels is independent of several well-known factors implicated in the development of hypertension, such as insulin resistance, pubertal status, and renal function. (Read the full article)

Wrapping very preterm newborns in polyethylene bags in the delivery room reduces hypothermia on admission to the NICU, but many infants remain cold despite their use. Placing polyethylene-wrapped infants on exothermic mattresses may reduce hypothermia but increase hyperthermia.

Placing polyethylene-wrapped very preterm infants on exothermic mattresses in the delivery room results in more infants with abnormal temperature and more hyperthermia on admission to the NICU. (Read the full article)

Monovalent rotavirus vaccine was introduced for infants in the United States in 2008. Previous US evaluations have not specifically assessed the performance of this vaccine under routine use.

Using the same methodology and covering the same time period, high effectiveness (~90%) was demonstrated for the monovalent and the pentavalent rotavirus vaccine series against rotavirus disease resulting in emergency department/inpatient care, in children up to 2 years of age.

Popular press and research show that sibling aggression is common. Too often, however, it is dismissed as benign, and other forms of child aggression, such as peer aggression, are considered more serious. Peer aggression is linked to poorer mental health.

Using a national probability sample, we show that the nature and severity of sibling aggression have negative links to children’s and adolescents’ mental health. We demonstrate that sibling and peer aggression are comparable their links to symptoms of distress. (Read the full article)

Racial and ethnic differences exist in age at diagnosis and early access to mental and behavioral health services among children with autism spectrum disorders (ASDs). ASDs are also associated with increased rates of other medical comorbidities that may require specialty care.

Significant racial and ethnic differences in use of specialty care and specialty procedures exist among children with documented ASD. (Read the full article)

Several studies have investigated the prevalence of chronic daily headache (CDH) and analyzed the risk factors for its persistence. However, the etiologic factors that lead to new-onset CDH remain unsettled in adolescents.

This study was the first incidence study of CDH conducted in young adolescents. We reported the incidence rates and found that some risk factors for incident chronic migraine and chronic tension-type headache were different. (Read the full article)

Obesity is associated with cardiometabolic risk factors and chronic conditions, such as type 2 diabetes. However, a proportion of overweight and obese youth remain free from cardiometabolic risk factors and are considered metabolically healthy.

This study provides insight into the determinants of cardiometabolic risk factors and the concept in health promotion of "fitness versus fatness." Hepatic lipid accumulation and not fitness level appears to drive cardiometabolic risk factor clustering among overweight and obese youth. (Read the full article)

Minority children are less likely than white children to be diagnosed and treated with attention-deficit/hyperactivity disorder. However, diagnosis patterns over time in early and middle childhood and whether confounding factors explain these disparities are not currently well understood.

Racial/ethnic disparities in attention-deficit/hyperactivity disorder diagnosis occur by kindergarten and continue until eighth grade. Racial/ethnic disparities among diagnosed children in medication use occur in both fifth and eighth grades. These disparities are not attributable to confounding factors. (Read the full article)

Because children often lack the physical strength, cognitive abilities, and fine motor skills to operate all-terrain vehicles (ATVs) properly, their risk of injury is greater.

During 2001–2010 in the United States, ~361 000 children aged ≤15 years were injured while riding ATVs. The decline in the injury rate during 2005–2010 might be related to the economic recession and decreased sales of new ATVs. (Read the full article)

Cornelia de Lange syndrome (CdLS) is a genetic syndrome with multisystem abnormalities. Infections are a significant cause of morbidity and mortality in affected patients and are typically attributed to anatomic abnormalities.

This study identified a high frequency of antibody immunodeficiency in CdLS subjects, indicating a critical need for screening and management of immunodeficiency in CdLS patients with a history of severe or recurrent infections. (Read the full article)

Screening for hypertension in asymptomatic children and adolescents occurs during routine care. For those with elevated blood pressure, a repeat measurement within 1 to 2 weeks is recommended. However, little is known about patterns of care after an incident elevated blood pressure.

In a population of 72 625 children and adolescents, 6108 (8.4%) had an incident elevated blood pressure. Among these, 1275 (20.9%) had their blood pressure measurement repeated within 1 month. However, few individuals with an incident elevated blood pressure subsequently developed hypertension. (Read the full article)

Pneumococcal conjugate vaccines are effective in preventing pneumococcal disease but are also costly. Although the current US immunization schedule recommends 4 doses, many countries have adopted 3-dose schedules that have worked well, but may provide less protection against pneumococcal disease.

Changing the US 13-valent pneumococcal conjugate vaccine schedule from 3 to 2 primary doses while keeping a booster dose would save $412 million annually but might lead to moderate increases in pneumococcal disease, especially otitis media and pneumonia. (Read the full article)

Violence involving firearms is a leading cause of death among US youth ages 14 to 24. The emergency department is the primary medical setting for care of assault-injured youth and an underused but important setting for violence-prevention programs.

Among assault-injured youth seeking emergency department care, firearm possession rates are high, most obtained outside of legal channels. Higher rates of negative retaliatory attitudes and substance use among those youth with firearms increases risk of future lethal violence. (Read the full article)

Obstacles to vaccine delivery, including poverty, reduced access to medical care, and incomplete understanding of vaccine safety and importance, result in suboptimal coverage rates in some populations, allowing for disease outbreaks. Multicomponent interventions are successful in increasing immunization coverage rates.

We show that collaboration with local resources, including the county health department and a large community-based organization, effectively increases immunization coverage rates in low-income, resource-poor children. (Read the full article)

Language barriers adversely affect health care access, utilization, outcomes, and patient safety. Trained formal interpreters can improve care quality and safety, but many patients and families with limited English proficiency do not receive appropriate language services during health care encounters.

Despite continued growth of the US population with limited English proficiency, federal language use standards, and enhanced education about appropriate use of language services, there has been only modest improvement over time in pediatricians’ use of language services. (Read the full article)

Prenatal diagnosis and clinical examination do not identify all infants with critical congenital heart defects before hospital discharge. To improve early critical congenital heart defect detection, New Jersey was the first state to implement legislatively mandated newborn pulse oximetry screening.

This report is the first to evaluate statewide pulse oximetry screening implementation. New Jersey had a high statewide screening rate and identified 3 infants with previously unsuspected critical congenital heart defects that otherwise might have resulted in significant morbidity and mortality.

Several risk factors for both overweight and obesity in childhood are identifiable during infancy.

A simple risk algorithm can be used to quantify risk of overweight in children. It can be used to help identify at-risk infants in a clinical setting to facilitate targeted intervention. (Read the full article)

There is wide variation in testing and treatment of children hospitalized with pneumonia. Limited data are available on diagnostic testing patterns and the association of test utilization with disposition outcomes for children with pneumonia evaluated in the emergency department (ED).

Significant variation exists in testing for pediatric pneumonia. EDs that use more testing have higher hospitalization rates. However, ED revisit rates were not significantly different between high- and low-utilizing EDs, suggesting an opportunity to reduce testing without negatively affecting outcomes. (Read the full article)

Retinal hemorrhage (RH) is an important sign of pediatric abusive head trauma. Raised intracranial pressure (ICP) is sometimes proposed as an alternate cause of RH in children being evaluated for possible child abuse.

Nontraumatic, markedly elevated ICP rarely causes RH in children. When it does, RH are superficial intraretinal and located adjacent to a swollen optic nerve head. This pattern does not match the widespread pattern seen in abusive head trauma. (Read the full article)

Respiratory syncytial virus (RSV) infection is a leading cause of hospitalization among infants. Most estimates of RSV hospitalization rates are imprecise, having been calculated by using retrospective discharge diagnosis data and stratified age groups no narrower than 6 to 12 months.

Prospective, population-based surveillance data for infants hospitalized with laboratory-confirmed RSV infection were combined with birth certificate information to yield more precise age-specific hospitalization rates. These data should help determine priorities for the use of existing and future RSV prophylaxis strategies. (Read the full article)

Diabetic ketoacidosis (DKA) is a short-term complication of type 1 diabetes and is a major cause of preventable hospitalization in children. Hospital resource utilization and readmission rates for DKA across the US are not known.

Readmission for DKA within a year of hospitalization is common, accounting for one-fifth of all DKA admissions. Resource use, hospital length of stay, and readmission rates vary widely across major US children’s hospitals, even after adjusting for hospital differences in patients. (Read the full article)

Previous research has demonstrated that pediatric injuries associated with television (TV) tip-overs are increasing, children aged ≤4 years are at highest risk for injury, and the head and neck are most commonly injured.

We analyzed a nationally representative sample comprising 22 years of data. On average, 17 313 children receive emergency treatment of a TV-related injury annually in the United States. The rate of injury attributable to falling TVs increased by 95% over 22 years. (Read the full article)

In 2001, an estimated 10 438 children were treated in US emergency departments for nonfatal choking on food. The foods most frequently associated with pediatric fatal choking are hot dogs, seeds, nuts, candy, and certain types of fruits and vegetables.

From 2001 through 2009, an estimated annual average of 12 435 children ages 0 to 14 years were treated in US emergency departments for nonfatal choking on food; 0- to 4-year-olds accounted for 61.7% of episodes. Foods most frequently involved were candy, meat, bone, and fruits/vegetables. (Read the full article)

Respiratory support is commonly given to newborn infants via a face mask in the delivery room. Respiratory support given to preterm infants via a single nasal prong may be more effective.

Compared with a face mask, using a single nasal prong to deliver respiratory support to preterm newborns did not result in less intubation and ventilation in the delivery room. (Read the full article)

Previous research on potential deleterious effects of typically developing children growing up in households with children with disability has produced mixed results. Research methods have been cited as a problem in many studies.

This is the largest known empirical study comparing functional impairment in siblings living with a child with disability and siblings residing with children who are typically developing. This study also follows the trajectory of functional impairment across 2 measurement periods. (Read the full article)

Sugar-sweetened beverage (SSB) consumption in school-age children and adolescents is linked to heavier weight, and decreased SSB consumption results in less weight gain. Reports regarding these associations among children aged 2 to 5 years have been mixed.

Preschool-aged and kindergarten children drinking SSB compared with infrequent/nondrinkers had higher BMI z scores. SSB consumption is also associated with higher weight status among children aged 2 to 5 years. (Read the full article)

Critical congenital heart disease (CCHD) was recently added to the US Recommended Uniform Screening Panel for newborns.

Routine screening could cost an estimated additional $6.28 per newborn and $40 385 per life-year gained. The incremental cost of screening might be approximately $0.50 per newborn with reusable sensors. Future analysis of newborn screening programs may help refine these projections.

Data available before the 1990s in addition to small studies with clinical populations have shown that ocular growth and development differ between extremely preterm and term-born children.

Contemporary data on long-term visual outcomes indicate that adolescents born extremely low birth weight and/or extremely preterm exhibit more visual sensory and perceptual morbidity than adolescents born at term. (Read the full article)

Despite declines in cigarette smoking, smokeless tobacco use among youth has remained unchanged in the United States. Modified or novel smokeless tobacco products are being increasingly promoted to youth in the United States as an alternative to smoking.

Among US students in grades 6 through 12, 5.0% used snuff or chewing or dipping tobacco, whereas 2.2% used snus or dissolvable tobacco products. Approximately two-thirds of smokeless tobacco users concurrently smoked combustible tobacco; risk perception of all tobacco products was protective of smokeless tobacco use. (Read the full article)

The American College of Surgeons National Surgical Quality Improvement Program-Pediatric has examined 30-day risk-adjusted outcomes in children’s surgery. Because of low event rates, initial efforts yielded valid models that did not meaningfully discriminate outcomes among over 20 participating institutions.

Programmatic growth, sampling algorithm refinement, and hierarchical modeling use have resulted in the ability to reliably discriminate performance among hospitals in multiple domains. We report the first actionable peer-reviewed risk-adjusted, multiinstitutional outcome data in children’s surgery. (Read the full article)

Blood cultures are a common investigation in children admitted to the hospital with skin and soft tissue infections. The yield of blood cultures in this condition is unknown.

Blood cultures are not useful in children admitted to the hospital with uncomplicated skin and soft tissue infections, and they may be associated with increased length of hospital stay. (Read the full article)
