Background: Attention-deficit/hyperactivity disorder (ADHD) has been shown to pose considerable clinical and economic burden; however, research quantifying the excess burden attributable to common psychiatric comorbidities of ADHD among pediatric patients is scarce. This study assessed the impact of anxiety and depression on healthcare resource utilization (HRU) and healthcare costs in pediatric patients with ADHD in the United States. Methods: Patients with ADHD aged 6–17 years were identified in the IQVIA PharMetrics Plus database (10/01/2015-09/30/2021). The index date was the date of initiation of a randomly selected ADHD treatment. Patients with ≥ 1 diagnosis for anxiety and/or depression during both the baseline (6 months pre-index) and study period (12 months post-index) were classified in the ADHD+anxiety/depression cohort; those without diagnoses for anxiety nor depression during both periods were classified in the ADHD-only cohort. Entropy balancing was used to create reweighted cohorts. All-cause HRU and healthcare costs during the study period were compared using regression analyses. Cost analyses were also performed in subgroups by comorbid conditions. Results: The reweighted ADHD-only cohort (N = 204,723) and ADHD+anxiety/depression cohort (N = 66,231) had similar characteristics (mean age: 11.9 years; 72.8% male; 56.2% had combined inattentive and hyperactive ADHD type). The ADHD+anxiety/depression cohort had higher HRU than the ADHD-only cohort (incidence rate ratios for inpatient admissions: 10.3; emergency room visits: 1.6; outpatient visits: 2.3; specialist visits: 5.3; and psychotherapy visits: 6.1; all p < 0.001). The higher HRU translated to greater all-cause healthcare costs; the mean per-patient-per-year (PPPY) costs in the ADHD-only cohort vs. ADHD+anxiety/depression cohort was $3,988 vs. $8,682 (p < 0.001). All-cause healthcare costs were highest when both comorbidities were present; among patients with ADHD who had only anxiety, only depression, and both anxiety and depression, the mean all-cause healthcare costs were $7,309, $9,901, and $13,785 PPPY, respectively (all p < 0.001). Conclusions: Comorbid anxiety and depression was associated with significantly increased risk of HRU and higher healthcare costs among pediatric patients with ADHD; the presence of both comorbid conditions resulted in 3.5 times higher costs relative to ADHD alone. These findings underscore the need to co-manage ADHD and psychiatric comorbidities to help mitigate the substantial burden borne by patients and the healthcare system. [ABSTRACT FROM AUTHOR]

Background. A−β+ ketosis-prone diabetes (KPD) in adults is characterized by presentation with diabetic ketoacidosis (DKA), negative islet autoantibodies, and preserved β-cell function in persons with a phenotype of obesity-associated type 2 diabetes (T2D). The prevalence of KPD has not been evaluated in children. We investigated children with DKA at "T2D" onset and determined the prevalence and characteristics of pediatric A−β+ KPD within this cohort. Methods. We reviewed the records of 716 children with T2D at a large academic hospital and compared clinical characteristics of those with and without DKA at onset. In the latter group, we identified patients with A−β+ KPD using criteria of the Rare and Atypical Diabetes Network (RADIANT) and defined its prevalence and characteristics. Results. Mean age at diagnosis was 13.7 ± 2.4 years: 63% female; 59% Hispanic, 29% African American, 9% non-Hispanic White, and 3% other. Fifty-six (7.8%) presented with DKA at diagnosis and lacked islet autoantibodies. Children presenting with DKA were older and had lower C-peptide and higher glucose concentrations than those without DKA. Twenty-five children with DKA (45%) met RADIANT A−β+ KPD criteria. They were predominantly male (64%), African American or Hispanic (96%), with substantial C-peptide (1.3 ± 0.7 ng/mL) at presentation with DKA and excellent long-term glycemic control (HbA1c 6.6% ± 1.9% at follow-up (median 1.3 years postdiagnosis)). Conclusions. In children with a clinical phenotype of T2D and DKA at diagnosis, approximately half meet criteria for A−β+ KPD. They manifest the key characteristics of obesity, preserved β-cell function, male predominance, and potential to discontinue insulin therapy, similar to adults with A−β+ KPD. [ABSTRACT FROM AUTHOR]

PURPOSE: This study aimed to describe opioid prescription patterns for children with vs. without cerebral palsy (CP). METHODS: This cohort study used commercial claims from 01/01/2015–12/31/2016 and included children aged 2–18 years old with and without CP. Opioid prescription patterns (proportion exposed, number of days supplied) were described. A zero-inflated generalized linear model compared the proportion exposed to opioids in the follow-up year (2016) and, among those exposed, the number of days supplied opioids between cohorts before and after adjusting for age, gender, race, U.S. region of residence, and the number of co-occurring neurological/neurodevelopmental disabilities (NDDs). RESULTS: A higher proportion of children with (n = 1,966) vs. without (n = 1,219,399) CP were exposed to opioids (12.1% vs. 5.3%), even among the youngest age group (2–4 years: 9.6% vs. 1.8%), and had a greater number of days supplied (median [interquartile range], 8 [5–13] vs. 6 [4–9] days; P < 0.05). Comparing children with opioid exposure with vs. without CP, a greater number of days supplied was identified for older age, Asian race/ethnicity, and without co-occurring NDDs, and a lower number of days supplied was observed for Black race/ethnicity and with ≥1 co-occurring NDDs. CONCLUSION: Children with CP are more likely to be exposed to opioids and have a higher number of days supplied. [ABSTRACT FROM AUTHOR]

American football is associated with the largest number of emergency department visits for pediatric sport-related traumatic brain injury, including concussions. Tackling is responsible for almost two-thirds of football concussions. Some have recommended implementing age restrictions on tackling in youth football. To determine whether the public would support age restrictions and the factors that may drive such support. Cross-sectional study. Summer wave of Porter Novelli's 2020 US ConsumerStyles survey. A total of 4053 adults. Respondents answered questions about a good age for children to start playing tackle football, past football playing history, concerns about safety, and the benefits and risks of playing football. Most respondents believed that middle (32.8%) or high (27.8%) school was a good age to start playing tackle football. About 1 in 5 (19.8%) respondents reported that children should never play tackle football. Certain groups of individuals were more likely to support children starting to play tackle football at high school age or above or to say that they should never play tackle football, including those with a bachelor's degree or higher (rate ratio [RR]HS+ = 1.41, 95% CI = 1.14, 1.76; RRNEVER = 2.70, 95% CI = 1.93, 3.78), those who did not have children under 18 (RRHS+ = 1.54, 95% CI = 1.26, 1.90; RRNEVER = 1.54, 95% CI = 1.14, 2.07), those who were not football fans (RRNEVER = 3.07, 95% CI = 2.32, 4.06), and those who were very (RRHS+ = 3.94, 95% CI = 2.87, 5.42; RRNEVER = 11.52, 95% CI = 7.32, 18.15) or somewhat (RRHS+ = 1.88, 95% CI = 1.41, 2.52) concerned about the safety of children. Despite acknowledging the benefits of playing football, many adults expressed concern about safety and endorsed high school age and older or never as a good age to start playing tackle football, highlighting a disconnect with current football program practices regarding age.

Flag football is promoted as a safer alternative to tackle football. This may be 1 reason why participation rates have risen by 39% over the past 3 years. Despite rising participation, epidemiologic research on sport-specific injuries and associated relative risk is lacking. To prospectively document the epidemiology of injuries in youth flag football. Descriptive epidemiology study. Regional and national youth flag football tournaments. Athletes (N = 1939; 1744 boys and 195 girls), ages 6 to 12 years. An athletic trainer prospectively monitored the athletes for sport-related injury and exposures. Athlete risks of injury and injury rates were calculated overall and by sex. Injury characteristics were reported for the total population and by sex. Forty-seven injuries to unique individuals were recorded in 1939 athletes with a total of 9228 athlete-exposures (AEs). The overall risk of injury was 2.4% (95% CI = 1.79%, 3.21%), with an overall injury rate of 5.1 per 1000 AEs (95% CI = 3.75, 6.77). Of the 47 injuries, 36 occurred in boys (8365 AEs), and 11 occurred in girls (863 AEs). A higher risk in girls was evidenced by both the injury risk ratio (2.73; 95% CI = 1.41, 5.30) and injury rate ratio of 2.96 (95% CI = 1.51, 5.82). The most common injury sites were the head/face/neck (n = 15, 31.9%), followed by the ankle/foot (n = 9, 19.1%). The most frequent types of injury were contusion (55.3%), sprain/subluxation (14.9%), and general trauma (10.6%); 74.5% of all injuries resulted from direct impact. Although the competition injury rate for youth flag football was lower than the values from studies reporting comparable tackle football data, the frequencies by body part, type, and mechanism were similar. Given that most injuries were related to some form of impact and predominantly contusions, adopting minimal protective equipment or padding may reduce the numbers of these injuries.

BACKGROUND: Ambient air pollution may be a developmental endocrine disruptor. In animal models, gestational and perinatal exposure to diesel exhaust and concentrated particulate matter alters anogenital distance (AGD), a marker of prenatal androgen activity, in both sexes. Little is known in humans. OBJECTIVES: We examined exposure to fine particulate matter (PM2.5) and nitrogen dioxide (NO2) in relation to human AGD at birth and at 1 year of age, focusing on exposures during critical windows of reproductive development: the male programming window (MPW; gestational weeks 8–14) and mini-puberty (postnatal months 1–3). METHODS: The Infant Development and Environment Study (TIDES) recruited first trimester pregnant women (β = 687) at four U.S. sites (Minneapolis, Minnesota; Rochester, New York; San Francisco, California; and Seattle, Washington) from 2010 to 2012. We measured anus to clitoris (AGD-AC) and anus to fourchette (AGD-AF) in female infants at birth; in males, we measured anus to penis (AGD-AP), anus to scrotum (AGDAS), and penile width at birth and at 1 year of age. Using advanced spatiotemporal models, we estimated maternal exposure to PM2.5 and NO2 in the MPW and mini-puberty. Covariate-adjusted, sex-stratified linear regression models examined associations between PM2.5 and NO2 and AGD. RESULTS: In males, a 1-μg/m³ increase in PM2.5 exposure during the MPW was associated with shorter AGD at birth, but a longer AGD at 1 year of age (e.g., birth AGD-AP: β = -0.35 mm; 95% CI: -0.62, -0.07; AGD-AS: β = 0.37 mm; 95% CI: 0.02, 0.73). Mini-pubertal PM2.5 exposure was also associated with shorter male AGD-AP (β = -0.50 mm; 95% CI: -0.89, -0.11) at 1 year of age. Although not associated with male AGD measures, 1-ppb increases in NO2 exposure during the MPW (β = -0.07 mm; 95% CI: -0.02, -0.12) and mini-puberty (β = -0.04 mm; 95% CI: -0.08, 0.01) were both associated with smaller penile width at 1 year of age. Results were similar in multipollutant models, where we also observed that in females AGD-AC was inversely associated with PM2.5 exposure, but positively associated with NO2 exposure. DISCUSSION: PM2.5 and NO2 exposures during critical pre- and postnatal windows may disrupt reproductive development. More work is needed to confirm these novel results and clarify mechanisms.

BACKGROUND: Gestational phthalate and phenol exposure disrupts adipogenesis, contributing to obesity in mice. Whether gestational phthalate or phenol exposure is associated with infant body composition has not been investigated in humans. OBJECTIVE: We examined associations between biomarkers of phthalate and phenol exposure in midpregnancy and infant size and body composition at birth and at 5 months of age. METHODS: Analyses were conducted among 438 infants from the Healthy Start prospective pregnancy cohort. Sixteen phthalate and phenol biomarkers were quantified in spot urine samples collected at 24–28 wk of gestation. Infant outcomes measured at birth and at 5 months of age included size [weight (in grams)] and body composition [fat and lean masses (in grams); percentage fat mass]. Single- (linear) and multipollutant (quantile g-computation) models were used to estimate associations of phthalate and phenol biomarkers with infant outcomes at birth and at 5 months of age. Models were adjusted for sociodemographics, sample collection timing, and lifestyle factors and used to examine for effect modification by infant sex. RESULTS: In single-pollutant models, mono-benzyl phthalate and di-n-butyl phthalate were inversely associated with percentage fat mass [ß: -0.49 (95% CI: -0:91, -0:08) and -0:51 (95% CI: -1.02, 0.01), respectively] in male but not female infants at birth. Similar, but less precise, associations were observed at 5 months of age. In multipollutant models, a 1-quartile increase in the phthalate and phenol biomarker mixture was inversely associated with percentage fat mass at birth [-1.06 (95% CI: -2.21, 0.1)] and at 5 months of age [-2.14 (95% CI: -3.88, -0.39)] among males, but associations were null among females [0.48 (95% CI: -0.78, 1.75) and -0.64 (95% CI: -2.68, 1.41), respectively]. Similar associations were observed with infant weight. CONCLUSION: In this U.S.-based prospective cohort, gestational phthalate and phenol biomarkers were inversely associated with infant weight and fat mass, particularly in males.

Background and Objectives: Prehospital Advanced Life Support (ALS) is important to improve patient outcomes in children with seizures, yet data is limited regarding national prehospital variation in ALS response for these children. We aimed to determine the variation in ALS response and prehospital administration of antiepileptic medication for children with seizures across the United States. Methods: We analyzed children <19 years with 9-1-1 dispatch codes for seizure in the 2019 National Emergency Medical Services Information System dataset. We defined ALS response as ALS-paramedic, ALS-Advanced Emergency Medical Technician, or ALS-intermediate responses. We conducted regression analyses to identify associations between ALS response (primary outcome), antiepileptic administration (secondary outcome) and age, gender, location, and US census regions. Results: Of 147,821 pediatric calls for seizures, 88% received ALS responses. Receipt of ALS response was associated with urbanicity, with wilderness (adjusted odds ratio [aOR] 0.44, 0.39-0.49) and rural (aOR 0.80, 0.75-0.84) locations less likely to have ALS responses than urban areas. Of 129,733 emergency medical service (EMS) activations with an ALS responder's impression of seizure, antiepileptic medications were administered in 9%. Medication administration was independently associated with age (aOR 1.008, 95% confidence interval [CI] 1.005-1.010) and gender (aOR 1.22, 95% CI 1.18-1.27), with females receiving medications more than males. Of the 11,698 children who received antiepileptic medications, midazolam was the most commonly used (83%). Conclusion: The majority of children in the US receive ALS responses for seizures. Although medications are infrequently administered, the majority who received medications had midazolam given, which is the current standard of care. Further research should determine the proportion of children who are continuing to seize upon EMS arrival and would most benefit from immediate treatment. [ABSTRACT FROM AUTHOR]

• Pediatric product-related injuries are an important public health problem. • Recent epidemiology remains unexamined for pediatric product-related injuries. • Pediatric product-related injury morbidity declined consistently during 2001–2020. • Pediatric product-related injury morbidity spectrum varied across subgroups. • Efforts should be enhanced to address pediatric product-related injury in the United States. Introduction: This study examined changes in product-related injury morbidity among under-20 Americans between 2001 and 2020. Method: Product-related injury morbidity data came from the National Electronic Injury Surveillance System (NEISS). Using age-standardized morbidity rates, the authors performed Joinpoint regression models to identify time periods with significant changes between 2001 and 2020 and quantified the annual magnitude of morbidity changes with annual percent changes (APCs) in rates and 95 % confidence intervals (CIs). Results: Age-standardized product-related injury morbidity declined consistently among under-20 Americans from 2001 to 2020 (from 7449.3 to 4023.5 per 100,000 persons; APC = -1.5 %, 95 % CI: −2.3 %, −0.7 %), with the most striking morbidity drop in 2019–2020 (-1576.8 per 100,000 persons). Sports and recreation equipment and home were the most common product and location, respectively, for nonfatal pediatric product-related injuries. Large morbidity differences and varying spectrum by product and by occurring location existed across sex and age groups. Conclusions: Product-related injury morbidity declined significantly among under-20 Americans between 2001 and 2020, but large variations remained across sex and age groups. Practical Applications: Further research is recommended to understand causal factors contributing to the observed decrease in product-related injury morbidity over the past 20 years and to understand product-related injury morbidity disparities across sex and age groups. Understanding of causal factors could lead to implementation of additional interventions to reduce product-related injury among children and adolescents. [ABSTRACT FROM AUTHOR]

Background Despite guidelines recommending narrow-spectrum perioperative antibiotics (NSPA) as prophylaxis for most children undergoing congenital heart disease (CHD) surgery, broad-spectrum perioperative antibiotics (BSPA) are variably used, and their impact on postoperative outcomes is poorly understood. Methods We used administrative data from U.S. hospitals participating in the Vizient Clinical Data Base. Admissions from 2011 to 2018 containing a qualifying CHD surgery in children 0–17 years old were evaluated for exposure to BSPA versus NSPA. Propensity score-adjusted models were used to compare postoperative length of hospital stay (PLOS) by exposure group, while adjusting for confounders. Secondary outcomes included subsequent antimicrobial treatment and in-hospital mortality. Results Among 18 088 eligible encounters from 24 U.S. hospitals, BSPA were given in 21.4% of CHD surgeries, with mean BSPA use varying from 1.7% to 96.1% between centers. PLOS was longer for BSPA-exposed cases (adjusted hazard ratio 0.79; 95% confidence interval [CI]: 0.71–0.89, P <.0001). BSPA was associated with higher adjusted odds of subsequent antimicrobial treatment (odds ratio [OR] 1.24; 95% CI: 1.06–1.48), and there was no significant difference in adjusted mortality between exposure groups (OR 2.06; 95% CI: 1.0–4.31; P =.05). Analyses of subgroups with the most BSPA exposure, including high-complexity procedures and delayed sternal closure, also did not find (but could not exclude) a measurable benefit from BSPA on PLOS. Conclusions BSPA use was common in high-risk populations, and varied substantially between centers. Standardizing perioperative antibiotic practices between centers may reduce unnecessary broad-spectrum antibiotic exposure and improve clinical outcomes. [ABSTRACT FROM AUTHOR]

OBJECTIVES: National guidelines recommend that children with sickle cell anemia receive annual transcranial Doppler (TCD) screening to assess stroke risk. Our objectives were to estimate the rate of TCD screening among privately insured children with sickle cell anemia, estimate out-of-pocket spending for TCD screening, and evaluate the association between TCD screening and enrollment in high-deductible health plans (HDHPs). STUDY DESIGN: Cross-sectional. METHODS: Using the 2009-2017 IBM MarketScan Commercial Database, we identified children aged 2 to 15 years who met a validated claims-based definition of sickle cell anemia. We calculated the proportion of children receiving annual TCD screening and out-of-pocket spending per TCD screen. Using logistic regression with generalized estimating equations, we modeled the receipt of annual TCD screening as a function of HDHP enrollment, controlling for demographics and year. RESULTS: The 2519 children in the analysis accounted for 7197 person-years of enrollment; 14% of person-years were from HDHP enrollees. During 2009-2017, the proportion of children receiving TCD screening ranged from 40% to 44%. Median out-of-pocket spending for TCD screening was $20 overall and $65 among HDHP enrollees. Out-of-pocket spending exceeded $100 for 27% of all screens and 42% of screens among HDHP enrollees. HDHP enrollment was not associated with TCD screening (adjusted odds ratio, 0.99; 95% CI, 0.85-1.15). CONCLUSIONS: Among privately insured children with sickle cell anemia, fewer than half received annual TCD screening. Out-of-pocket spending exceeded $100 for 27% of TCD screens. Although HDHP enrollment was not associated with TCD screening, additional studies are needed to assess whether cost sharing might deter this screening. [ABSTRACT FROM AUTHOR]

Background/Objective. Growth and obesity have been associated with increased risk of islet autoimmunity (IA) and progression to type 1 diabetes. We aimed to estimate the effect of energy-yielding macronutrient intake on the development of IA through BMI. Research Design and Methods. Genetically at-risk children (n = 5,084) in Finland, Germany, Sweden, and the USA, who were autoantibody negative at 2 years of age, were followed to the age of 8 years, with anthropometric measurements and 3-day food records collected biannually. Of these, 495 (9.7%) children developed IA. Mediation analysis for time-varying covariates (BMI z-score) and exposure (energy intake) was conducted. Cox proportional hazard method was used in sensitivity analysis. Results. We found an indirect effect of total energy intake (estimates: indirect effect 0.13 [0.05, 0.21]) and energy from protein (estimates: indirect effect 0.06 [0.02, 0.11]), fat (estimates: indirect effect 0.03 [0.01, 0.05]), and carbohydrates (estimates: indirect effect 0.02 [0.00, 0.04]) (kcal/day) on the development of IA. A direct effect was found for protein, expressed both as kcal/day (estimates: direct effect 1.09 [0.35, 1.56]) and energy percentage (estimates: direct effect 72.8 [3.0, 98.0]) and the development of GAD autoantibodies (GADA). In the sensitivity analysis, energy from protein (kcal/day) was associated with increased risk for GADA, hazard ratio 1.24 (95% CI: 1.09, 1.53), p = 0.042. Conclusions. This study confirms that higher total energy intake is associated with higher BMI, which leads to higher risk of the development of IA. A diet with larger proportion of energy from protein has a direct effect on the development of GADA. [ABSTRACT FROM AUTHOR]

We assessed rotavirus vaccine impact using data on acute gastroenteritis (AGE) encounters within an integrated healthcare delivery system during 2000–2018. Following rotavirus vaccine introduction, all-cause AGE rates among children <5 years declined by 36% (95% confidence interval [CI]: 32%–40%) for outpatient and 54% (95% CI: 46%–60%) for inpatient encounters.

Simple Summary: Diffuse intrinsic pontine gliomas in children are rare, highly malignant infiltrating tumors in a location precluding surgical resection. The absence of non-invasive correlates of response and disease progression in these tumors invites the exploration of imaging biomarkers. Magnetic resonance spectroscopy is an advanced imaging technique for measuring cell metabolites. This study evaluated whether measurements of in vivo cell metabolites using magnetic resonance spectroscopy may serve as biomarkers of response to therapy, including progression. Single-voxel magnetic resonance spectra were serially acquired in two cohorts of patients with these tumors treated with radiation therapy with or without concurrent chemotherapy and prior to progression: 14 participants were enrolled in a clinical trial of adjuvant glioma-associated antigen peptide vaccines and 32 patients were enrolled who did not receive adjuvant vaccine therapy. In the vaccine cohort, an elevated myo-inositol/choline ratio after 2–3 doses was associated with longer survival. Scans performed up to 6 months before death showed a terminal decline in the myo-inositol/choline ratio. Higher myo-inositol/choline ratios following radiation therapy, consistent with less proliferate tumors and decreased cell turnover, were associated with longer survival, suggesting that this ratio can serve as a biomarker of prognosis following radiation therapy. Purpose: Diffuse intrinsic pontine gliomas (DIPG) are highly aggressive tumors with no currently available curative therapy. This study evaluated whether measurements of in vivo cell metabolites using magnetic resonance spectroscopy (MRS) may serve as biomarkers of response to therapy, including progression. Methods: Single-voxel MR spectra were serially acquired in two cohorts of patients with DIPG treated with radiation therapy (RT) with or without concurrent chemotherapy and prior to progression: 14 participants were enrolled in a clinical trial of adjuvant glioma-associated antigen peptide vaccines and 32 patients were enrolled who did not receive adjuvant vaccine therapy. Spearman correlations measured overall survival associations with absolute metabolite concentrations of myo-inositol (mI), creatine (Cr), and n-acetyl-aspartate (NAA) and their ratios relative to choline (Cho) during three specified time periods following completion of RT. Linear mixed-effects regression models evaluated the longitudinal associations between metabolite ratios and time from death (terminal decline). Results: Overall survival was not associated with metabolite ratios obtained shortly after RT (1.9–3.8 months post-diagnosis) in either cohort. In the vaccine cohort, an elevated mI/Cho ratio after 2–3 doses (3.9–5.2 months post-diagnosis) was associated with longer survival (rho = 0.92, 95% CI 0.67–0.98). Scans performed up to 6 months before death showed a terminal decline in the mI/Cho ratio, with an average of 0.37 ratio/month in vaccine patients (95% CI 0.11–0.63) and 0.26 (0.04–0.48) in the non-vaccine cohort. Conclusion: Higher mI/Cho ratios following RT, consistent with less proliferate tumors and decreased cell turnover, were associated with longer survival, suggesting that this ratio can serve as a biomarker of prognosis following RT. This finding was seen in both cohorts, although the association with OS was detected earlier in the vaccine cohort. Increased mI/Cho (possibly reflecting immune-effector cell influx into the tumor as a mechanism of tumor response) requires further study. [ABSTRACT FROM AUTHOR]

Objective: Little is known about parents' willingness to vaccinate their children against COVID-19. We assessed the prevalence of vaccine hesitancy among parents with a child or adolescent aged 12-15 years, examined predictors of parents' COVID-19 vaccine hesitancy, their reasons for resisting a pediatric COVID-19 vaccine, and the correlation between parents' intentions to vaccinate their child and the acceptance of a vaccine for themselves. Methods: We conducted a national online survey of 637 parents of a child or adolescent aged 12-15 years in March 2021, before COVID-19 vaccines had been approved for this age group. We assessed univariate predictors of vaccine hesitancy, and we used logistic regression analysis to assess independent effects of variables on vaccine hesitancy. Results: Nearly one-third (28.9%; 95% CI, 25.5%-32.5%) of respondents reported pediatric vaccine hesitancy. Vaccine-hesitant parents were less knowledgeable about vaccines, more accepting of vaccine conspiracies, and less worried about COVID-19 risks to their child's health than vaccine-accepting parents were. Vaccine hesitancy was higher among female (vs male), single (vs married/living as married), older (vs younger), low income (vs high income), non–college graduates (vs college graduates), and Republican (vs Democrat) parents. The primary concerns expressed by vaccine-hesitant parents pertained to vaccine safety rather than vaccine effectiveness. One-quarter of vaccine-hesitant parents preferred that their child obtain immunity through infection rather than vaccination. Non–vaccine-hesitant parents' reasons for vaccinating focused on protecting the health of their child and others. Childhood COVID-19 vaccine acceptance was strongly associated with parents' intentions to get the vaccine for themselves. Conclusion: A messaging strategy for effective public health interventions that includes educating the public about vaccination, countering misinformation about vaccine development and safety, and stressing the safety of approved COVID-19 vaccines may boost vaccine acceptance among vaccine-hesitant parents.

Background: To estimate the incidence, risk factors, and impact on mortality and functional outcomes for early coagulopathy after the return of spontaneous circulation (ROSC) in pediatric out-of-hospital cardiac arrest (OHCA) patients. Methods: A post hoc analysis of the Therapeutic Hypothermia after Pediatric Cardiac Arrest Out-of-Hospital (THAPCA-OH) trial was conducted. Early coagulopathy was defined as presence of at least one of the following coagulation abnormalities upon admission: international standard ratio (INR), platelets, and age-adjusted activated partial thromboplastin time (APTT) within 6 h after OHCA and before therapeutic hypothermia initiation. The outcomes included 28-day mortality and functional prognosis. Multivariable logistic regression models were used to explore risk factors and association between early coagulopathy and outcomes. Results: Of the 227 patients included, 152 (67%) were male and the median age was 2.3 years [interquartile range (IQR), 0.7–8.6 years]. The overall 28-day mortality was 63%. The incidence of early coagulopathy was 46%. Lower age, longer duration of chest compression, lower temperature, and higher white blood cell (WBC) upon admission increased the risk of early coagulopathy. Early coagulopathy [OR, 2.20 (95% CI, 1.12–4.39), P = 0.023] was independently associated with 28-day mortality after adjusting for confounders. Conclusions: Early coagulopathy occurred in almost half of pediatric patients with OHCA. Lower age, longer duration of chest compression, lower temperature, and higher WBC increased the risk. The development of early coagulopathy was independently associated with increased mortality. [ABSTRACT FROM AUTHOR]

Simple Summary: Despite significant survival improvements for adolescents and young adults (AYAs) with cancer overall, several subsets of AYAs lag behind. This is especially true for AYAs diagnosed with metastatic disease, where, for many types of cancer, fewer than 20% of patients are alive 5 years later. Which sociodemographic subgroups of AYAs are at highest risk for presenting with metastatic disease is not well understood. In this study using United States Surveillance, Epidemiology, and End Results Program data, we found significantly increased risk of metastatic disease across many cancer sites for non-Hispanic Blacks, males, and low socioeconomic status AYAs. In particular, metastatic melanoma was striking for demonstrating multiple sociodemographic disparities. Results of this study shed light on the relative roles of age, race/ethnicity, sex, and socioeconomic status in metastatic disease presentation. These will inform future, cancer-specific research to elucidate biological, social, and environmental mechanisms underlying these associations with metastatic disease. Having metastatic disease at diagnosis poses the great risk of death among AYAs with cancer from all sociodemographic subgroups. This "landscape" study utilized United States Surveillance, Epidemiology, and End Results Program data from 2000–2016 to identify subgroups of AYAs at highest risk for presenting with metastases across twelve cancer sites having a poor-prognosis (5-year survival <50% with metastases). Adjusted odds ratios for risk of metastatic disease presentation were compared for AYAs in aggregate and by sociodemographic subgroup (race/ethnicity, sex, socioeconomic status [SES]). In general, AYAs who were male, racial/ethnic minorities, or low SES were at consistently greatest risk of metastases. Strikingly, having metastatic melanoma was independently associated with multiple AYA sociodemographic subgroups, including males (aOR 3.11 [95% CI 2.64–3.66]), non-Hispanic Blacks (4.04 [2.32–7.04]), Asian Pacific Islanders (2.99 [1.75–5.12]), Hispanics (2.37 [1.85–3.04]), and low SES (2.30 [1.89–2.80]). Non-Hispanic Blacks were more likely to present with metastatic cancer in all sites, except for bone, rhabdomyosarcoma, and stomach. Low SES AYAs are more likely to present with metastatic melanoma, bone tumors, soft tissue sarcomas, breast, cervical, lung, and stomach carcinomas. Building on these results, future cancer-specific studies should investigate the connection between sociodemographic risk factors and biological drivers of metastases. This line of research has potential to inform targeted public health and screening efforts to facilitate risk reduction and earlier detection of these deadly diseases. [ABSTRACT FROM AUTHOR]

Background: Coronavirus disease 2019 (COVID-19) vaccine hesitancy has remained a significant concern among adults worldwide. However, not much is known about parental vaccine hesitancy for getting children vaccinated for COVID-19 in the U.S. Thus, the purpose of this study was to conduct a national assessment of parents' preferences for COVID-19 vaccination of children using the evidence-based Multi-Theory Model (MTM) and explore the predictors of vaccine hesitancy. Methods: To participate in this study, a national random sample of parents (n=263) took a valid and reliable online questionnaire based on the MTM. Independent samples t test, chi-square test, multiple logistic regression was utilized to analyze data. Results: More than two-fifths (42%) of the participating parents were not willing to get their children vaccinated for COVID-19. Parental vaccination status, booster dose acceptance, education, and political affiliation were significant predictors of willingness to get children vaccinated for COVID-19. In the multiple logistic regression analyses, behavioral confidence and participatory dialogue (i.e., perceived advantages versus disadvantages) were statistically significant predictors of COVID-19 vaccination hesitancy for children among the participating parents. Conclusion: Given the multiple factors that were found influential in parental hesitancy for COVID-19 vaccination among children, multimodal and evidence-based interventions are needed to increase the uptake of COVID-19 vaccines among children by influencing the parents' perceptions, increasing their confidence, dispelling misinformation, and reducing constraints for vaccination. Such interventions should emphasize communication and messaging that is truthful, interactive, scientifically correct, and to be delivered in a variety of community-based settings.

To evaluate the relationship between infant age of egg introduction and malnutrition‐related growth outcomes in the United States, we analysed secondary data of 1716 mother–child dyads in the Infant Feeding Practices Study II and its Year 6 Follow‐Up Study. Malnutrition‐related growth outcomes included body mass index z‐score (BMIZ), obesity (weight‐for‐height z‐score [WHZ] ≥3 or BMIZ ≥ 2), WHZ, wasting (WHZ < −2), height‐for‐age z‐score (HAZ), and stunting (HAZ < –2). Infant age at egg introduction was analysed as a continuous variable. We used generalised estimating equations to estimate the mean difference in continuous outcomes and relative risk [RR]) for binary outcomes, adjusting for related maternal and child confounders. We also explored interactions with child sex, maternal race/ethnicity, maternal educational level, ever breastfeeding, and formula feeding. In the total sample, a later infant age at egg introduction was associated with a lower mean difference in HAZ (confounder‐adjusted mean difference = −0.08, 95% confidence interval [CI]: −0.12 to −0.03 per month) and a higher risk of stunting (confounder‐adjusted RR = 1.17, 95% CI: 1.03–1.33 per month) at 6 years. The associations between infant age at egg introduction and 12‐month growth outcomes differed by child sex. Among females but not among males, later introduction of eggs was associated with a lower mean WHZ (−0.06 [−0.12 to 0.00] per month) at 12 months. Later egg introduction during infancy was associated with a lower mean HAZ and a higher risk of stunting in 6‐year‐old children. Besides this, it was associated with a lower WHZ among females at 12 months. Key messages: This secondary data analysis evaluated the relationship between infant age at egg introduction and malnutrition‐related growth outcomes among young US children within the Infant Feeding Practices Study II and its Year 6 Follow‐up Study.In the total sample, a later infant age at egg introduction was associated with a lower mean 6‐year height‐for‐age z‐score and a higher risk of stunting at 6 years.The associations between infant age at egg introduction and 12‐month growth outcomes differed by child sex. Later introduction of eggs was associated with a lower mean weight‐for‐height z‐score among females. However, this association was not observed among males. [ABSTRACT FROM AUTHOR]

BACKGROUND: Prenatal phthalate exposure has been associated with lower birth weight but also higher weight in childhood. Few studies have examined weight or adiposity from birth to childhood and thus cannot assess growth trajectories associated with exposure. OBJECTIVE: We assessed associations between maternal phthalate exposures in pregnancy and child weight and adiposity measured prenatally through childhood (3–6 years of age). METHODS: Within The Infant Development and the Environment Study (TIDES), a prospective pregnancy cohort, we analyzed a panel of phthalate metabolites in urine collected at two visits from early and late gestation (푁 = 780). We estimated average phthalate metabolite associations with child weight 푧-scores from ~20 wk gestation (estimated by ultrasound), birth, and 1, 3, 4, and 6 years of age using linear mixed-effects (LME) models. We also modeled associations with adiposity 푧-scores from birth (weight for length) and 1, 3, 4, and 6 years of age [body mass index (BMI)] using LME models. RESULTS: For weight, we observed inverse associations between several phthalate metabolites and birth weight 푧-scores, but no associations were observed with postnatal weight 푧-scores in LME models. Regarding adiposity, we observed inverse associations between phthalate metabolites and weight-for-length 푧-scores at birth, but positive associations were observed with BMI 푧-scores at 3–4 years of age in LME models. For example, mono-ethyl phthalate was associated with a 0.17-unit decrease in birth weight-for-length 푧-score [95% confidence interval (CI): –0:29, –0:05] and a 0.18-unit increase in 4-years-of-age BMI 푧-score (95% CI: 0.04, 0.32). DISCUSSION: We observed associations between prenatal exposure to phthalates and lower weight at birth but not at childhood follow-up visits. However, for adiposity, we observed an interesting pattern of association with low adiposity at delivery as well as high adiposity at 3–4 years of age. Although it is not clear from our results whether these associations occur within the same children, such a pattern of adiposity in early life has been linked to cardiometabolic disease in adulthood and deserves special attention as an outcome in the study of prenatal exposures in the developmental origins of health and disease.

Objectives: Testing remains critical for identifying pediatric cases of COVID-19 and as a public health intervention to contain infections. We surveyed US parents to measure the proportion of children tested for COVID-19 since the start of the pandemic, preferred testing venues for children, and acceptability of school-based COVID-19 testing. Methods: We conducted an online survey of 2074 US parents of children aged ≤12 years in March 2021. We applied survey weights to generate national estimates, and we used Rao–Scott adjusted Pearson χ2 tests to compare incidence by selected sociodemographic characteristics. We used Poisson regression models with robust SEs to estimate adjusted risk ratios (aRRs) of pediatric testing. Results: Among US parents, 35.9% reported their youngest child had ever been tested for COVID-19. Parents who were female versus male (aRR = 0.69; 95% CI, 0.60-0.79), Asian versus non-Hispanic White (aRR = 0.58; 95% CI, 0.39-0.87), and from the Midwest versus the Northeast (aRR = 0.76; 95% CI, 0.63-0.91) were less likely to report testing of a child. Children who had health insurance versus no health insurance (aRR = 1.38; 95% CI, 1.05-1.81), were attending in-person school/daycare versus not attending (aRR = 1.67; 95% CI, 1.43-1.95), and were from households with annual household income ≥$100 000 versus income <$50 000-$99 999 (aRR = 1.19; 95% CI, 1.02-1.40) were more likely to have tested for COVID-19. Half of parents (52.7%) reported the pediatrician's office as the most preferred testing venue, and 50.6% said they would allow their youngest child to be tested for COVID-19 at school/daycare if required. Conclusions: Greater efforts are needed to ensure access to COVID-19 testing for US children, including those without health insurance. [ABSTRACT FROM AUTHOR]

Objective: The COVID-19 pandemic led to a substantial drop in US children's preventive care, which had not fully rebounded by the end of 2020. We sought to estimate the overall prevalence of missed, skipped, or delayed preventive checkups among households with children in the last 12 months because of the pandemic. Methods: We used data from the US Census Bureau's Household Pulse Survey, Phase 3.1 (collected April–May 2021). The analytic sample included 48 824 households with ≥1 child or adolescent aged <18 years. We estimated both national and state-level prevalences, examined associations with sociodemographic and household characteristics, and described reasons for missed or delayed preventive visits. Results: Overall, 26.4% (95% CI, 25.5%-27.2%) of households reported that ≥1 child or adolescent had missed or delayed a preventive visit because of COVID-19; percentages varied by state, from 17.9% in Wyoming to 37.0% in Vermont. The prevalence of missed or delayed preventive visits was significantly higher among respondents who reported material hardships (ie, not caught up on rent/mortgage, difficulty paying usual household expenses, children not eating enough because of lack of affordability) than among respondents who did not report material hardships. The most common reasons for missing or delaying preventive visits were concern about visiting a health care provider, limited appointment availability, and the provider's location being closed. Conclusions: Programs and policies could reduce gaps in children's preventive care caused by the pandemic, with a particular focus on addressing social determinants of health. [ABSTRACT FROM AUTHOR]

The article discusses a 2022 study on the impact of long-term ambient air pollution on childhood eczema in the U.S. Topics covered include the link of long-term ambient nitrogen dioxide (NO2) concentrations with eczema incidence in the first year of life, and eczema's association with increased risk for multiple atopic diseases like food allergy, asthma and allergic rhinitis. Also noted is the increased risk for allergic diseases if there are exposures that increase eczema risk.
