The number of individuals diagnosed with autism spectrum disorders (ASDs) continues to increase in the United States and other developed countries. Most prevalence estimates indicate that ASD is diagnosed less commonly in Hispanic individuals compared with non-Hispanic (NH) white populations.

Prevalence of ASD in Arizona’s population-based cohort is higher than reported previously. Prevalence in the Hispanic population and NH white population increased significantly over time, with a significant decrease in the gap between Hispanic and NH white prevalence. (Read the full article)

For children and young people with life-limiting conditions, palliative care services should be available, but few national or local data are available to estimate the burden of these conditions.

The prevalence of life-limiting conditions in children and young people in England was double the previously reported estimates, at 32 per 10 000 population. This identifies a need for specialist pediatric palliative care services. (Read the full article)

Evaluating dehydration severity is a challenging task. Clinical dehydration scores that combine multiple clinical findings are promising. One clinical dehydration scale score has been developed and subsequently evaluated; however, few participants in the derivation and validation studies were significantly dehydrated.

In children requiring intravenous rehydration, the dehydration scale displayed moderate reliability and weak associations with objective measures. Thus, although the scale can assist in assessing dehydration, it should not be used in isolation to dictate interventions (eg, intravenous rehydration, hospitalization). (Read the full article)

Following a rapid increase from 1980 to 2001, the prevalence of obesity among school-age children and adolescents in the United States has plateaued. Few studies have examined obesity trends among younger children in the past decade, and findings are inconsistent.

Among children aged <6 years at this multisite pediatric practice, the prevalence of obesity was fairly stable during 1999–2003, but substantially decreased during 2004–2008. This decrease was smaller among children insured by Medicaid than children insured by non-Medicaid health plans. (Read the full article)

Assessing for adequacy of supervision in the clinical setting is challenging and may result in significant variability in care. Clinicians must quickly decide if a child and family necessitate direct counseling, further intervention, or require reporting to state agencies.

This study identified the most important characteristics for the evaluation of the adequacy of supervision of a young child. A standardized scale using these characteristics may result in an efficient means to reduce variability in care. (Read the full article)

Overweight and obese children have a higher prevalence of several cardiovascular disease (CVD) risk factors. There is growing evidence demonstrating that CVD risk factors present during childhood persist into adulthood.

US adolescents had no significant change in prehypertension/hypertension and borderline-high/ high low-density lipoprotein cholesterol prevalence from 1999–2000 to 2007–2008; however, prediabetes/diabetes increased by 14%. (Read the full article)

The association of retinal hemorrhages (RHs) with abusive head trauma (AHT) is robust; 46% to 100% RHs are reported in AHT. There is potential selection bias with risk of circular reasoning because the majority of studies describing RH focus on AHT.

This is the first prospective observational study defining prevalence and distribution of RH in critically ill children excluding those with AHT. Severe multilayered RH were rare and observed in children with accidental fatal head injury, severe coagulopathy, severe sepsis, or a combination of these factors. (Read the full article)

Male circumcision reduces risk of HIV acquisition in men by 60% and is associated with other health benefits. Compared with adult circumcision, infant male circumcision is safer, less expensive, and represents a cost-saving intervention for HIV prevention in many settings.

IMC is little known in East Africa and is not routinely practiced. This is the first study to assess acceptability and uptake of IMC in East Africa among parents who were actually offered the procedure. (Read the full article)

Rotavirus vaccine efficacy is lower in low-income settings with the highest child mortality due to diarrhea. In recently published clinical trials of rotavirus vaccines in Africa, waning of efficacy was also noted among children aged ≥1 year.

These data offer the first evidence of the duration of protection of the pentavalent rotavirus vaccine against severe rotavirus disease after routine use of the vaccine in a developing country setting. (Read the full article)

Siblings and other contacts of abused children, especially twins, are thought to be at higher risk for abuse than other children. However, the rate at which screening tests identify injuries in contacts is currently unknown.

Contacts of abused children with serious injuries have fractures identified on skeletal survey at significant rates. Twins are at substantially increased risk for fracture. Physical examination findings were not sensitive for fractures. (Read the full article)

Children without any underlying medical condition who walk on their toes are referred to as idiopathic toe-walkers. The prevalence and early course of idiopathic toe-walking are unknown.

This study establishes the prevalence and early spontaneous course of idiopathic toe-walking in a large, well-defined cohort of 5.5-year-old children. (Read the full article)

Children’s mastery of fundamental movement skills is correlated with a number of health benefits, including higher levels of physical activity, cardiorespiratory fitness, perceived scholastic and athletic competence, and lower levels of overweight.

This is the first study to examine the associations between low skill competence (a new and novel way to report motor skills) and a range of health-related and sociodemographic factors in a large representative sample of children and youth. (Read the full article)

Exergaming offers a physical activity (PA) alternative for youth that may be attractive in our increasingly technophilic society. Exergaming increases PA and decreases sedentary time, but most exergame studies are clinically based and focus on measuring energy expenditure during exergaming.

One-quarter of adolescents exergamed at intensity levels that could help them achieve PA recommendations. Exergamers were more likely to be female, play nonactive video games, watch ≥2 hours of television per day, be stressed about weight, and be nonsmokers. (Read the full article)

Some groups of children are especially prone to develop overweight and obesity. Overweight in children affects their physical and psychological health and shortens life expectancy. Overweight in children with Down syndrome (DS) is attributed to their commonly found comorbidities.

This study provides prevalence rates of overweight and obesity in a nationwide sample of otherwise healthy children with DS. Overweight is observed from young ages in healthy children with DS and those with severe congenital heart defects. (Read the full article)

Osteopathy of prematurity continues to occur in preterm infants. Osteopathy of prematurity can cause rib fractures in ex-preterm infants.

Rib fractures in ex-preterm infants are often posterior and multiple. Posterior rib fractures may not be diagnostic of nonaccidental injury in ex-preterm infants. (Read the full article)

High doses of radiation have been linked to cancer induction in irradiated populations such as atomic bomb survivors. Medical imaging directs significant radiation doses to human tissues. Epidemiological studies have demonstrated that children are more sensitive to radiation than adults.

The link between cancer induction from moderate radiation doses such as diagnostic imaging is controversial. This study uses Food and Drug Administration–accepted formulas to calculate theoretical risk of breast cancer induction in female pediatric trauma patients receiving diagnostic imaging of the thoracic spine.

The prevalence of asthma and associated urgent medical visits vary dramatically across neighborhoods in New York City. Some, but not all, children with asthma wheeze when they exercise.

Exercise-induced wheeze was more common for asthmatic children living in neighborhoods with higher versus lower asthma prevalence. Because exercise-induced symptoms indicate a propensity for rapid-onset symptoms, this increased prevalence may contribute to the observed increase in urgent medical visits. (Read the full article)

Adequate vitamin D is essential for skeletal health in developing children. Although excess body weight is associated with risk of vitamin D deficiency, the national prevalence of vitamin D deficiency in overweight and obese children is unknown.

Vitamin D deficiency is highly prevalent in overweight and obese children, and severely obese and minority children are disproportionately affected. There are many modifiable factors associated with vitamin D deficiency in overweight and obese children. (Read the full article)

Among youth with asthma, tobacco smoke exposure causes increased asthma morbidity. Little is known about changes over time in tobacco smoke exposure among youth with asthma in a national sample.

Our analysis reveals a decrease in environmental tobacco smoke exposure among children and adolescents with current asthma in the United States from 1988–1994 to 2005–2010, but a majority of youth with asthma remain exposed to environmental tobacco smoke. (Read the full article)

Celiac disease is increasing in several countries and has emerged as a public health problem. Infant feeding has been suggested to affect celiac disease development and/or clinical expression. However, evidence-based complementary feeding strategies are limited.

Significant difference in celiac disease prevalence between 2 cohorts of 12-year-olds indicates an option for disease prevention. The cohorts differed in infant feeding, and our findings suggest that gradual introduction of gluten in small amounts during ongoing breastfeeding is favorable. (Read the full article)

Despite downward trends, the US teen birth rate remains among the highest of developed nations. Childhood maltreatment may place teens at higher risk, but inferences are weak given a lack of prospective study and control for alternative explanations.

Results from the first controlled, prospective study of nulliparous teenagers confirm that victims of maltreatment are more than twice as likely as their nonmaltreated peers to experience a teen childbirth after controlling for demographic confounds and other known risk factors.

Adherence to infant feeding recommendations in the United States is low. The prevalence of early introduction of solid foods (<4 months of age) in the United States has been estimated to range from 19% to 29%.

Mothers’ most commonly cited reasons for early solid food introduction include perception of readiness, hunger, wanting to feed something in addition to breast milk or formula, perception of interest in solids, advice from a clinician, and to improve infant’s sleep. (Read the full article)

Early detection for children with autism leads to better outcomes; early screening is critical. The Modified Checklist for Autism in Toddlers (M-CHAT) is a widely used instrument for early autism screening and is recommended by the American Academy of Pediatrics.

This large study provides empirical support for population screening for autism spectrum disorders and the use of the M-CHAT in primary care settings. This study provides updated results to facilitate use and scoring of the M-CHAT by clinical providers. (Read the full article)

The systemic nonselective β-blocker propranolol hydrochloride is increasingly used as first-line management for infantile hemangiomas. Superficial nonulcerating lesions do not require systemic medications. Case series have suggested the efficacy of timolol; however, its safety has been questioned.

This randomized controlled trial indicates that timolol maleate 0.5% gel is a well-tolerated, safe, and effective treatment of superficial infantile hemangiomas. (Read the full article)

The American Academy of Pediatrics recommends that all preterm infants receive human milk; however, little is known about the use of human milk in US advanced care neonatal units.

Routine use of human milk and use of donor milk in neonatal advanced care units increased from 2007 to 2011, particularly among units providing intensive care. There is geographic variation in the use of human milk in these units. (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.

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. (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)

Bronchopulmonary dysplasia is associated with increased long-term neurodevelopmental and respiratory morbidity. Inhaled nitric oxide given to reduce morbidity in very preterm infants does not reduce the prevalence of bronchopulmonary dysplasia and has uncertain effects on long-term outcome.

Inhaled nitric oxide (5 ppm) given early in the course of respiratory illness in infants born before 29 weeks of gestation is not associated with changes in developmental or respiratory outcomes at 2 years of age corrected for prematurity. (Read the full article)

The Faces Pain Scale–Revised and Color Analog Scale are self-report pain scales that are commonly used for children in the clinical and research settings.

The Faces Pain Scale–Revised and Color Analog Scale overall demonstrate strong psychometric properties in children 4 to 17 years of age, including within subgroups of age, sex, and ethnicity. Convergent validity, however, is questionable in children <7 years old. (Read the full article)

Adult males are known to have a greater overall likelihood of death than female adults. Among children, excess male mortality is known for specific conditions but not as a general phenomenon.

Males are more likely to die during childhood and adolescence than their female peers from not only injuries but also from a wide variety of medical conditions, suggesting the existence of either a female robustness factor or a male vulnerability factor. (Read the full article)

Children with congenital heart disease demonstrate a high prevalence of low-severity developmental problems in the areas of language, motor skills, attention, and executive function. Systematic evaluation has been recommended to promote early detection of problems and ensure appropriate intervention.

This study presents results of longitudinal testing in early childhood. Developmental delays were common. Feeding difficulty and medical and genetic comorbidities increased risk for delays. Exposure to risk and prevalence of delay change over time; therefore, repeated evaluations are warranted. (Read the full article)

There are misconceptions regarding childhood phimosis. Textbooks still teach that male children should have retractable foreskin by age 3. Young children are referred for evaluation for phimosis, which is a commonly used diagnosis for postneonatal circumcision.

We found a high prevalence of physiologic phimosis in kindergarten children, up to 44% at age 6. We also reviewed the incidence of other congenital abnormalities in this coastal Chinese city. The management and complications of these conditions were analyzed. (Read the full article)

Diabetic ketoacidosis (DKA) is a life-threatening condition and often the presenting symptom of newly diagnosed type 1 or type 2 diabetes in youth. SEARCH previously reported that the prevalence of DKA at diagnosis was 25.5% in 2002–2003.

DKA in youth with type 1 diabetes remains a problem, with almost one-third presenting with DKA. Among youth with type 2 diabetes, DKA was less common and decreased by ~10% per year, suggesting improved detection or earlier diagnosis. (Read the full article)

In the United States, given the high burden of disease, influenza vaccine is recommended for all children from age 6 months. The paucity of vaccine effectiveness data in children <2 years has led some to argue against routine vaccination in this age group.

This study reveals the effectiveness of trivalent influenza vaccine in young children and supports the current Advisory Committee on Immunization Practices recommendation. This study provides the strongest evidence to date confirming the effectiveness of trivalent influenza vaccine in children <2 years of age. (Read the full article)

Invasive pneumococcal disease causes enormous morbidity in children. The spectrum and severity of illness caused by pneumococcal serotypes not present in the current vaccine, and whether the clinical profile and severity of disease have changed, are largely unknown.

Initial data suggest that nonvaccine serotypes are more common in children with underlying conditions, who have greater morbidity from disease. In the post-PCV13 era, a larger proportion of patients are hospitalized, but mortality rates are unchanged. (Read the full article)

The role of inhaled nitric oxide (INO) in the treatment of newborns with congenital diaphragmatic hernia (CDH) is poorly defined and not rigorously proven. Contemporary rates of INO use for CDH have not been reported.

INO use in neonates with CDH is widespread, and has increased in many US tertiary pediatric hospitals without associated decrease in extracorporeal membrane oxygenation use or mortality. (Read the full article)

The short-term immunogenicity and safety of a HPV4 vaccine have been previously evaluated in preadolescents and adolescents. To date, no long-term studies of the safety, effectiveness, and immunogenicity of the HPV4 vaccine have been reported in this age group.

The HPV4 vaccine administered to adolescents demonstrated durability in clinically effective protection and sustained antibody titers over 8 years. These data, along with extensive postapproval safety surveillance data, should help reinforce national recommendations for HPV vaccination of preadolescents and adolescents. (Read the full article)

Many pediatric acute respiratory tract infections (ARTI) are viral and do not require antimicrobial treatment. Recent estimates of antimicrobial overprescribing for these infections, defined based on the published bacterial disease prevalence among all ARTI, are not available.

Based on the published bacterial prevalence rates for pediatric ARTI, antimicrobial agents are prescribed almost twice as often as expected to outpatients nationally, amounting to an estimated 11.4 million potentially preventable antimicrobial prescriptions annually. (Read the full article)

Neonatal circumcision in the United States has been estimated to be performed in ~58% of all neonates, and varies by US geographic region.

This study estimates neonatal and postneonatal circumcision rates among commercially insured males aged 0 to 18 years that were performed in both inpatient and outpatient settings. This study also estimates indications and payments for the procedure. (Read the full article)

Most studies of fetal alcohol syndrome and fetal alcohol spectrum disorders (FASD) prevalence in the general population of the United States have been carried out using passive methods (surveillance or clinic-based studies), which underestimate rates of FASD.

Using active case ascertainment methods among children in a representative middle class community, rates of fetal alcohol syndrome and total FASD are found to be substantially higher than most often cited estimates for the general US population. (Read the full article)

Menu labels depicting physical activity calorie equivalents may lead to ordering of fast food meals totaling fewer calories for adults. The effects of physical activity calorie equivalent labeling on parents’ fast food decisions for their children have not been examined.

Parents shown menus with any type of caloric content label may order fast food meals totaling fewer calories for their children. Menu labels showing physical activity equivalents may be more likely to influence parents to encourage their children to exercise. (Read the full article)

Worldwide prevalence estimates of Duchenne and Becker muscular dystrophies (DBMD) vary, likely due to differences in diagnostic criteria, ascertainment, and survival. To date, no population-based prevalence data for DBMD by race/ethnicity have been published in the United States.

Approximately 2 per 10 000 boys, ages 5 to 9 years, in 6 sites in the United States have DBMD; prevalence remained rather constant across 4 birth cohorts that spanned 2 decades. Prevalence differed among selected racial/ethnic groups across the time period examined. (Read the full article)

Off-label prescription of inhaled nitric oxide (iNO) to neonates <34 weeks’ gestation has increased during the past decade. In early 2011, the National Institutes of Health determined that the available evidence did not support iNO use in this population.

Use of iNO among neonates <34 weeks’ gestation has increased since 2011, entirely from greater use in extremely preterm neonates. Off-label prescription of this drug now accounts for nearly half of all iNO use in American NICUs. (Read the full article)

Preterm infants are at an increased risk of infections; therefore, vaccination is of particular importance. Because immune response data reported for preterm infants may vary according to gestational age and vaccination timing, vaccine responses in this population warrant additional research.

This study evaluated 13-valent pneumococcal conjugate vaccine in preterm infants. Results suggest that this vaccine was well tolerated and immunogenic; most subjects achieved serotype-specific immunoglobulin G antibody levels and functional antibody responses likely to correlate with protection against invasive disease.

There is concern that the Bayley-III overestimates developmental functioning in preterm populations. The ability of the Bayley-III Cognitive and Language scales to predict later functioning in very preterm children has not been examined.

The norms on the Bayley-III Cognitive and Language scales at 24 months had low sensitivity for impairment across general cognitive, verbal and nonverbal reasoning domains at 4 years, which was better detected using cut-points based on local term-born reference data. (Read the full article)

Prophylactic vaccination of young women 16 to 26 years of age with the 9-valent human papillomavirus (HPV)–like particle (9vHPV) vaccine prevents infection and disease with vaccine HPV types.

These data support bridging the efficacy findings with 9vHPV vaccine in young women 16 to 26 years of age to girls and boys 9 to 15 years of age and implementation of gender-neutral HPV vaccination programs in preadolescents and adolescents. (Read the full article)

Attitudes and knowledge about appropriate management of common childhood illnesses may lead parents to mistakenly believe antibiotics are needed. Differences existed in antibiotic knowledge and attitudes between parents of Medicaid- and commercially insured children and according to other sociodemographic variables.

Despite efforts to decrease unnecessary antibiotic use, misconceptions about antibiotic use persist and continue to be more prevalent among parents of Medicaid-insured children. Tailored efforts for socioeconomically disadvantaged populations remain warranted to decrease parental drivers of unnecessary antibiotic prescribing. (Read the full article)

Weak recommendations exist to guide emergent neuroimaging decisions in children with first, unprovoked seizures. The prevalence of and risk factors associated with clinically relevant abnormalities on neuroimaging have not been well defined in prospective studies.

Clinically relevant intracranial abnormalities on neuroimaging occur in 11% of children with first, unprovoked seizures. Emergent/urgent abnormalities, however, occur in <1%, suggesting that most of these children do not require emergent neuroimaging. Specific clinical findings identify patients at higher risk.

The routine childhood immunization schedule is crowded during the first 2 years, leading to deferred doses and limiting the addition of new vaccines. Combination vaccines can reduce the "shot burden" and improve coverage rates and timeliness.

Antibody response rates to antigens contained in an investigational hexavalent vaccine (DTaP5-IPV-Hib-HepB) were noninferior to licensed comparator vaccines when given as a 3-dose infant series. The safety profile was similar to control except for increased rates of mild-to-moderate, self-limited fever. (Read the full article)
