Recent case reports have described acute life-threatening complications in adolescents who present to health services having lost large amounts of weight but who are not underweight. Little is known about the frequency of life-threatening complications in these adolescents.

Over 6 years, we found more than a fivefold increase in the incidence of hospitalized adolescents who, apart from not being underweight, have diagnostic features of anorexia nervosa. This group experienced a similar profile of acute complications of anorexia nervosa. (Read the full article)

Among US youth 6 to 15 years of age there are differences in strength by gender and age. Little is known about differences in strength by weight status in the US pediatric population.

This study provides current US nationally representative reference values for 4 measures of strength in youth 6 to 15 years old. Body weight was associated with strength, but the association varied depending upon the measure. (Read the full article)

Cardiovascular risk begins in childhood. New clinical guidelines established a care strategy for lowering risks. Incorporation of guidelines into routine practice lags due to barriers related to knowledge and attitudes about guidelines, as well as behaviors of practitioners, patients, and clinical systems.

This study demonstrated that a multifaceted approach including tools, education, and support for changes in practice systems can accelerate the adoption of guidelines during routine pediatric well-child visits, compared with dissemination of the guidelines alone. (Read the full article)

Adolescent males from low-income communities are a group at increased risk of obesity and related health concerns. Obesity prevention interventions targeting adolescents have so far had mixed success. Targeted interventions, tailored for specific groups, may be more appealing and efficacious.

A multicomponent school-based intervention using smartphone technology can improve muscular fitness, movement skills, and key weight-related behaviors among low-income adolescent boys. (Read the full article)

Stimulant medications are indicated for treatment of childhood attention-deficit/hyperactivity disorder (ADHD), but there is concern that stimulants may negatively affect growth. However, no longitudinal, population-based studies have examined height into adulthood for childhood ADHD cases.

This longitudinal, population-based study shows that neither childhood ADHD itself nor treatment with stimulants is associated with significant deficits in height into adulthood. (Read the full article)

Adolescents and adults born early preterm have higher blood pressure and altered glucose metabolism compared with their term born peers. Evidence of an atherogenic lipid profile is inconsistent. Whether these risks apply to those born less preterm is not known.

In adolescence, girls have higher blood pressure and boys a more atherogenic lipid profile than their term born peers. Overall, our results are consistent with a dose-response relationship between shorter length of gestation and increasing levels of cardiovascular risk factors. (Read the full article)

Partner violence victimization is associated with mental and behavioral health effects linked to weight gain. Childhood maltreatment is directly linked to obesity and associated with neuroanatomic and psychosocial changes, which heighten vulnerability to subsequent stressors.

This study finds that dating violence victimization is associated with greater increases in BMI from adolescence to young adulthood among women. Women with previous exposure to childhood sexual abuse are especially vulnerable to dating violence–related increases in BMI. (Read the full article)

Puberty suppression has rapidly become part of the standard clinical management protocols for transgender adolescents. To date, there is only limited evidence for the long-term effectiveness of this approach after gender reassignment (cross-sex hormones and surgery).

In young adulthood, gender dysphoria had resolved, psychological functioning had steadily improved, and well-being was comparable to same-age peers. The clinical protocol including puberty suppression had provided these formerly gender-dysphoric youth the opportunity to develop into well-functioning young adults. (Read the full article)

Cancer continues to be the leading disease-related cause of death among children and adolescents in the United States. More information is needed about recent trends.

This study provides recent, robust data supporting the increasing incidence of pediatric thyroid cancer and rising overall cancer rates among African American children and adolescents and is the first study to describe increasing rates of pediatric renal carcinoma. (Read the full article)

Vaccinating youth is among the nation’s highest health care priorities. Despite proven health benefits, human papillomavirus vaccination rates remain low.

This is the first known study to test whether vaccination of high-risk adolescents is related to their or their parents’ previous knowledge levels. In the results presented, neither parental nor adolescent knowledge is related to subsequent adolescent vaccination. (Read the full article)

Childhood immunization might contribute to an increase in asthma prevalence. Previous studies have been contradictory, and many lack sufficiently large control groups of nonimmunized children.

Pertussis immunization in infancy does not increase the risk of asthma medication in adolescents. Our study presents convincing evidence that pertussis immunization in early childhood can be considered safe with respect to long-term development of asthma. (Read the full article)

More than 200 million children <5 years old in low- and middle-income countries are not reaching their potential in cognitive development because of factors associated with poverty.

Poverty affects children’s cognition as early as 7 months and continues to increase until 5 years of age. It is mainly mediated by parental education, birth weight, home stimulation throughout the 5 years, and growth in the first 24 months. (Read the full article)

Children who have attention-deficit/hyperactivity disorder (ADHD) attending clinical services have poorer outcomes in adolescence on a range of measures. However, it is unknown how early in development these impairments appear, particularly for community-ascertained samples.

At age 6 to 8 years, children in the community with ADHD have significantly poorer mental health, academic performance and social function compared with control children. Children who have impairing ADHD symptoms should be referred early for assessment and intervention. (Read the full article)

Admissions to the ICU during off-hours (nights and weekends) have been variably associated with increased mortality in both adults and children. Changes in staffing patterns, patient characteristics, or other factors may have influenced this relationship over time.

This study demonstrates in a large, current, multicenter database sample that off-hours admissions to PICUs are not associated with increased risk-adjusted mortality. Admissions in the morning from 6:00 am to 10:59 am are associated with increased mortality and warrant further attention. (Read the full article)

In 2003, the US Food and Drug Administration issued warnings about hyperglycemia and diabetes with second-generation antipsychotics (SGAs). Since 2004, hyperglycemic and diabetes risk with SGAs has been stated in product labels, and published guidelines have recommended baseline metabolic screening.

Between 2006 and 2011, 11% of children 2 to 18 years starting an SGA had baseline glucose assessed. Youth at risk for diabetes may not be identified. Further, lack of screening impedes determining the contribution of SGAs to hyperglycemia. (Read the full article)

Allostatic load (AL), a biomarker of cardiometabolic risk, predicts the onset of the chronic diseases of aging including cardiac disease, diabetes, hypertension, and stroke. Socioeconomic-related stressors, such as low family income, are associated with AL.

African American youth who grow up in neighborhoods in which poverty levels increase across adolescence evince high AL. The study also highlights the benefits of emotional support in ameliorating this association. (Read the full article)

The built environment may affect weight status by presenting opportunities or barriers for exercise and nutritious eating. Although there is substantial cross-sectional evidence linking neighborhood factors and childhood obesity, causal uncertainty remains, owing to conceptual and methodological challenges.

This prospective study examined neighborhood influences on obesity during the transition to adolescence, a sensitive period for excess weight gain. Girls living in neighborhoods characterized by physical disorder or increased access to food and service retailers exhibited higher obesity risk. (Read the full article)

Earlier adiposity rebound may increase fatness in later life; however, there is limited evidence from large cohorts of contemporary children with direct measures of fatness in adolescence or adulthood.

Early adiposity rebound is strongly associated with increased BMI and fatness in adolescence. Future preventive interventions should consider targeting early childhood to delay timing of adiposity rebound. (Read the full article)

Restrictive feeding by parents is associated with poorer eating self-regulation and increased child weight status. However, this association could be due to confounding home environmental or genetic factors that are challenging to control.

Differential maternal restrictive feeding is associated with differences in twins' caloric compensation and BMI z score. Controlling for the shared home environment and partially for genetics, these findings further support a true (ie, unconfounded) association between restriction and childhood obesity. (Read the full article)

Preterm birth and faster infant growth have been identified as independent risk factors for autism-spectrum disorders (ASD). However, associations between prematurity and ASD-related traits as a continuum and effects of infant growth among those born preterm are still little studied.

VLBW young adults reported higher levels of ASD-related traits, particularly traits related to poorer social skills. Within the VLBW group, faster growth in weight, height, and head circumference from birth to term was associated with lower levels of ASD-related traits. (Read the full article)

In 2000/2001, the American Academy of Pediatrics published recommendations for attention-deficit/hyperactivity disorder (ADHD) care. According to pediatricians’ self-report of adoption of these guidelines, community-based ADHD care appears to be marginally adequate.

Using reviews of >1500 patient charts, this study demonstrates that community-based ADHD care is not consistent with evidence-based practice. Furthermore, variability in much of community-based ADHD care is unrelated to the provider, suggesting that innovative, system-wide interventions are needed to improve ADHD care.

Youth in foster care are at higher risk of health problems at entrance and during their stays in care. Little is known about this group’s risk of health problems in young adulthood, in comparison with other populations of young adults.

This is the first prospective study to our knowledge demonstrating that former foster youth are at higher risk of chronic health problems than economically secure and insecure general population young adults. (Read the full article)

Studies have shown that reciprocal vocalizations between mother and infant have positive effects on language development. It has been shown that girls acquire vocabulary and language skills earlier than boys.

Mothers more readily respond to their infant’s vocal cues than fathers, and infants show a preferential vocal response to their mothers in the first months of life. Mothers respond preferentially to infant girls versus boys at birth and 44 weeks. (Read the full article)

In developed countries, child health disparities across wealth gradients are commonly widening; at the same time, child mortality in low- and middle-income countries is declining. Whether these declines are associated with widening or narrowing disparities is unknown.

A systematic analysis of the evidence on child mortality gradients by wealth in less-developed countries shows that mortality is declining fastest among the poorest in most countries, leading to declining disparities in this important indicator of child health. (Read the full article)

National adolescent vaccination coverage estimates in 2013 among 13- to 17-year-olds are 86% for Tdap vaccine and 78% for MCV4. Comparatively, coverage with ≥3 doses of HPV vaccine is 38% among girls and 14% among boys.

One-fourth of 11-year-olds had HPV vaccine co-administered with Tdap vaccine, compared with two-thirds who had MCV4 co-administered. Whereas by age 17 years, >92% received Tdap vaccine and MCV4, only half of girls and one-fifth of boys completed HPV vaccination. (Read the full article)

Obesity among youth can have immediate health effects as well as longer-term consequences during adulthood. Overweight/obese children and adolescents are much more likely than normal-weight children to become overweight/obese adults.

This large, multisite longitudinal study examines patterns of exit from and entry into obesity between childhood and adolescence. Socioeconomic factors, body image, television habits, and parental obesity were important predictors of whether children remained obese or became obese. (Read the full article)

Research suggests that appearance-focused messages and exaggerated depictions of sexual activity in the media negatively influence adolescents’ body and sexual self-perceptions. As adolescents increasingly use the Internet to explore their sexuality, health risks related to online behaviors should be identified.

This 4-wave study examined the prevalence and development of 2 receptive and 2 interactive sex-related online behaviors and their relations with adolescents’ body and sexual self-perceptions. It further investigated which parental strategies regarding Internet use may reduce risky sex-related online behaviors. (Read the full article)

Children who suffer abusive head trauma (AHT) have lasting health and development problems. AHT can reduce life expectancy dramatically. AHT’s contribution to the burden of disease has been estimated only as part of a broad category of intentional injury.

The DALY burden of a severe AHT case averages 80% of the burden of death, with most survivors dying before age 21 years. Even mild AHT is extremely serious, with lasting sequelae that exceed the DALY burden of a severe burn. (Read the full article)

Pediatric Brain Injury Research Network investigators recently derived a highly sensitive clinical prediction rule for pediatric abusive head trauma (AHT).

The performance of this AHT screening tool has been validated. Four clinical variables, readily available at the time of admission, detect pediatric AHT with high sensitivity in intensive care settings. (Read the full article)

Lead is an ubiquitous environmental pollutant, and no safe threshold for blood lead level in children has been discovered yet. Prenatal lead exposure affects growth of children.

Low level of prenatal lead exposure of <5.0 μg/dL affects postnatal children’s growth, which was further intensified by low calcium intake. (Read the full article)

Infants with Prader-Willi syndrome suffer from hypotonia, muscle weakness, and motor developmental delay and have increased fat mass combined with decreased muscle mass. Growth hormone improves body composition and motor development.

Ultrasound scans confirmed decreased muscle thickness in infants with Prader-Willi syndrome, which improved as result of growth hormone treatment. Muscle thickness was correlated to muscle strength and motor performance. Catch-up growth in muscle thickness was related to muscle use independent of growth hormone. (Read the full article)

Syndrome-specific standardized growth curves are not currently available for non–growth hormone–treated subjects with Prader-Willi syndrome and are required for monitoring growth and development in this rare obesity-related disorder.

Standardized growth curves were useful in monitoring growth and development in these subjects with Prader-Willi syndrome and for the management of growth hormone treatment of both genders, particularly those aged 3 to 18 years. (Read the full article)

There is a debate about whether e-cigarettes will benefit public health. However, there is little knowledge about how e-cigarette users and dual users (those using both e-cigarettes and tobacco cigarettes) differ from other adolescents on a range of variables.

Teenagers who only used e-cigarettes were intermediate in levels of risk and protective factors between nonusers and those who used both cigarettes and e-cigarettes. This raises a question about whether e-cigarettes recruit low-risk youth to tobacco product use. (Read the full article)

Hospitalized pediatric patients are often exposed to many medications during an inpatient admission. Drug–drug interactions may increase the risk of developing medication-related adverse drug events, leading to serious clinical morbidity and mortality.

Exposure to "major" potential drug–drug interactions occurs in 41% of pediatric hospitalizations in children’s hospitals. One-half of all these exposures were due to less common specific drug pairs (≤3% of patients exposed per hospital day) and thus may be less clinically familiar. (Read the full article)

Prenatal alcohol exposure can cause congenital neuropsychological and behavioral disabilities in later life. These usually lead to secondary disabilities (adverse outcome when the individual interacts with environmental settings), such as problems with school, the law, alcohol, or drugs.

This was a 30-year psychosocial register–based follow-up on adults with fetal alcohol syndrome and state care comparison group. The FAS-group had lower education and higher rates of unemployment, social welfare, and mental health problems than peers. Rates of criminality did not differ. (Read the full article)

Maternal depression has been associated with adolescent engagement in risky behaviors such as substance use. However, there is a lack of longitudinal research examining timing-specific effects in this relationship.

The results of this study indicate that youth exposed to increasing levels of maternal depressive symptoms in middle childhood are more likely to engage in substance use and delinquent behaviors and have an earlier debut age of these behaviors. (Read the full article)

Fasting insulin levels in childhood are increasingly being used as a surrogate for insulin resistance and risk of later type 2 diabetes, despite only a moderate correlation with whole-body insulin sensitivity and few data related to adult outcomes.

Elevated insulin values between the ages of 3 and 6 years are associated with an elevated risk for later type 2 diabetes. In 9- to 18-year-olds, elevated BMI (but not insulin values) is associated with later type 2 diabetes. (Read the full article)

Adolescent relationship abuse (ARA) is prevalent in confidential clinic settings such as school health centers (SHCs) and is associated with poor health outcomes. No evidence-based interventions target reduction of ARA in the SHC setting.

This study provides the first evidence of the potential benefits of a brief provider-delivered universal education and counseling intervention in SHCs to address and prevent a major public health problem: ARA. (Read the full article)

There is extensive literature documenting that children experiencing foster care placement have myriad adverse developmental outcomes, including poor academic achievement. However, such children face a host of other risk factors that may jeopardize healthy development independent of foster care placement.

Using statewide administrative data from Wisconsin, we observed children before, during, and after foster care placement and compared their educational outcomes with those of the general population, as well as with children more similar in terms of unobserved characteristics.

Although pediatric professional guidelines emphasize addressing a child’s social environment in the context of well child care, it remains unclear whether screening for unmet basic needs at visits increases low-income families’ receipt of community-based resources.

This study demonstrates that systematically screening and referring for social determinants of health during primary care can lead to the receipt of more community resources for families. (Read the full article)

Head Start, a federally funded preschool program for low-income US children, has been reported to have beneficial effects on developmental outcomes. The association of Head Start participation with changes in children’s BMI has not been examined.

Preschool-aged children with an unhealthy weight status who participated in Head Start had a significantly healthier BMI by kindergarten entry age than comparison children in a primary care health system (both those receiving and those not receiving Medicaid). (Read the full article)

Studies examining early postnatal discharge and readmission for jaundice report conflicting results. Infants born 37 to 38 weeks’ gestation have an increased risk for readmission for jaundice; however, the impact of early discharge on this group has not been investigated.

Early postnatal discharge was significantly associated with readmission for jaundice. Of the infants discharged early, those born 37 to 38 weeks’ gestation, born via vaginal delivery, born to Asian mothers, or were breastfed had the greatest risk for readmission. (Read the full article)

Researchers speculate that children with fetal alcohol spectrum disorders often are not recognized or diagnosed correctly.

This is the first study to assess the rate of missed diagnoses and misdiagnosis in foster and adopted children with fetal alcohol spectrum disorders. (Read the full article)

Light and intermittent smoking are harmful, but increasingly common, smoking patterns. It is unknown how adolescents perceive these smoking patterns, and whether these views differ by sociodemographic characteristics, and exposure to and use of tobacco.

US adolescents perceive light and intermittent smoking as significantly less dangerous than heavier smoking. One in 4 adolescents believes intermittent smoking causes little to no harm. Perceptions of relative safety were common among smokers. (Read the full article)

Tapentadol is used in the treatment of chronic pain, specifically diabetic neuropathy. It has known action on the μ-opioid receptor leading to drowsiness and apneas. There is no published information on the effects of tapentadol in small children.

After an accidental overdose in a child, tapentadol may be expected to cause μ-opioid clinical effects similar to other opioids. While the opioid effects predominate sympathomimetic effects are also seen. The risk of respiratory depression and dyspnea should be acknowledged. (Read the full article)

Pediatric obstructive sleep apnea syndrome (OSAS) has been associated with decreased health-related quality of life (QoL). Observational studies suggest that adenotonsillectomy for pediatric OSAS improves QoL, but these studies did not use a randomized study design or a control group of children with OSAS managed nonsurgically.

A prospective, randomized controlled study of adenotonsillectomy for pediatric OSAS showed significantly greater QoL and symptom improvements in children undergoing adenotonsillectomy than in the nonsurgical control arm. The extent of improvement was not appreciably influenced by baseline OSAS severity or obesity. (Read the full article)

Adults born very preterm or with very low birth weight have a lower likelihood of leaving their childhood home, and starting romantic relationships, and are older when experiencing first intercourse or having their first child than their term-born peers.

Compared with term-born individuals, those born preterm perceived themselves less attractive and were less likely to have cohabited or experienced first-time sexual intercourse by young adulthood. This outcome indicates that social outcomes are different among preterm-born individuals. (Read the full article)

Immune-related bioactive proteins are highly concentrated in the colostrum of mothers who deliver preterm infants. Oropharyngeal administration was proposed as a safe and feasible alternative method of providing colostrum to immunocompromised premature infants.

Oropharyngeally administered colostrum during the first few days of life increased urinary secretory immunoglobulin A and lactoferrin, decreased urinary interleukin-1β, reduced salivary transforming growth factor-β1 and interleukin-8, and reduced the occurrence of clinical sepsis in extremely premature infants.

Although headache is a common symptom after minor blunt head trauma in children, controversy exists whether the presence of headache increases the risk of traumatic brain injury.

Clinically important traumatic brain injuries are rare, and traumatic brain injuries on computed tomography are very uncommon in children with minor blunt head trauma when headaches are their only sign or symptom. (Read the full article)

Current recommendations for the first outpatient visit for newborns are based on known health risks during the first week of life. Knowledge of the relationship between early well child visits and hospital readmissions may inform newborn health policy interventions.

Newborns who have a first well child visit within the recommended time period after hospital discharge are substantially less likely be readmitted. Obstacles to early follow-up should be addressed to reduce the risk of readmission in this population. (Read the full article)
