Measurement invariance of the Wechsler Intelligence Scale for Children, Fifth Edition (WISC-V) 10 subtest primary battery was evaluated across sex, age (6-8, 9-11, 12-14, and 15-16 year-olds), and three diagnostic (attention-deficit/hyperactivity disorder, anxiety, and encephalopathy) groups within a large clinical sample (N = 5359) referred to a…

Autistic children have a high prevalence of co-occurring mental health, developmental/behavioral, and medical conditions, but research on sex/gender differences has been mixed. We used Florida healthcare claims data to characterize sex differences (female/male) in co-occurring conditions among autistic children ages 1-21 (N = 83,500). After…

Background: Many reviews aim to compare numerous treatments and report results stratified by subgroups (eg, by disease severity). In such cases, a network meta-analysis model including treatment by covariate interactions can estimate the relative effects of all treatment pairings for each subgroup of patients. Two key assumptions underlie such…

Sleep disorders often co-occur with autism spectrum disorder. They further exacerbate autism spectrum disorder symptoms and interfere with children's and parental quality of life. This study examines whether gastrointestinal dysfunctions increase the odds of having sleep disorders in 610 children with idiopathic autism spectrum disorder, aged 2-18…

The present study used nationally representative data from the U.S. Panel Study of Income Dynamics (PSID) merged with census-track data from the American Community Survey (ACS) to model race-ethnic disparities in overweight, obesity, and obesity-related disease among children and adolescents as a function of neighborhood race-ethnic segregation,…

We present three statistical methods for causal analysis in life course research that are able to take into account the order of events and their possible causal relationship: a cross-lagged model, a latent growth model (LGM), and a synthesis of the two, an autoregressive latent trajectories model (ALT). We apply them to a highly relevant…

Few large epidemiological studies have examined the co-occurrence of autism and asthma. We performed a cross-sectional study to examine this association using the 2007 National Survey of Children's Health dataset (n = 77,951). We controlled for confounders and tested for autism-secondhand smoke interaction. Prevalence of asthma and autism…

This year's "America's Children in Brief" highlights selected indicators by metropolitan status to give the reader a closer look at how well-being is influenced by the type of community in which children and their families live.

Objectives: To describe children with congenital bleeding disorders that present in a manner that may be concerning for non-accidental trauma (NAT), and to evaluate associations with disease and demographic characteristics. Methods: Ten year retrospective charts of subjects were reviewed at a Hemophilia Treatment Center. Demographic, historical,…

Category-based induction requires selective use of different relations to guide inferences; this article examines the development of inferences based on ecological relations among living things. Three hundred and forty-six 6-, 8-, and 10-year-old children from rural, suburban, and urban communities projected novel "diseases" or "insides" from one…

This year's Federal Interagency Forum on Child and Family Statistics' (Forum) report provides the Nation with carefully selected key national indicators of children's well-being and monitors changes in these indicators. The purposes of this report are to improve reporting of Federal data on children and families; make the most relevant data on the…

Age and ethnic group differences in cold weather and contagion or germ theories of infectious disease were explored in two studies. A cold weather theory was frequently invoked to explain colds and to a lesser extent flu but became less prominent with age as children gained command of a germ theory of disease. Explanations of how contact with…

For more than 25 years, Advocates for Children of New Jersey (ACNJ) has produced the New Jersey KIDS COUNT Data Book, an annual statewide profile of child well-being. With KIDS COUNT represented in each state and several U.S. territories, ACNJ is part of a comprehensive effort to not only track how well kids are faring across New Jersey, but also…

Intestinal disaccharidase activities were measured in 199 individuals with autism to determine the frequency of enzyme deficiency. All patients had duodenal biopsies that were evaluated morphologically and assayed for lactase, sucrase, and maltase activity. Frequency of lactase deficiency was 58% in autistic children less than or equal to 5 years…
