Findings from the Adverse Childhood Experiences (ACE) study articulated the negative effects of childhood trauma on long-term well-being. The purpose of the current study is to examine the associations between ACEs experienced in infancy and toddlerhood and adaptive behavior and academic status in middle childhood. We used data collected from a sample of low-income families during the impacts study of Early Head Start (EHS). Data were collected by trained interviewers demonstrating at least 85% reliability with protocols...

BACKGROUND: Preterm birth leads to multiple morbidities affecting the health of a child. Lack of information on the health impact of prematurity hinders the possibility of any effective public health interventions in this regard. Our aim was to determine the association between preterm birth and Health-Related Quality of Life (HRQOL) among 3 years old children in the Gampaha district, Sri Lanka. METHODS: A community-based retrospective cohort study was conducted among 790 preterm and term born children who were 03 years old...

BACKGROUND: Both short sleep duration and sleep-disordered breathing (SDB) are associated with poor neurocognitive development. However, the co-contributions of short sleep duration and SDB on neurodevelopment in pre-school children are relatively unknown. METHODS: We assessed both sleep duration and SDB by quarterly questionnaire from three months to two years of age among Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort participants. Group-based modeling determined trajectories of total, daytime, and nighttime sleep duration and SDB...

BACKGROUND: Pediatric adenotonsillectomies are common and carry known risks of potentially severe complications. Complications that require a revisit, to either the emergency department or hospital readmission, increase costs and may be tied to lower reimbursements by federal programs. In 2011 and 2012, recommendations by pediatric and surgical organizations regarding selection of candidates for ambulatory procedures were issued. We hypothesized that guideline-associated changes in practice patterns would lower the odds of revisits...

Although historically, treatment of amblyopia has been recommended prior to closure of a critical window in visual development, the existence and duration of that critical window is currently unclear. Moreover, there is clear evidence, both from animal and human studies of deprivation amblyopia, that there are different critical windows for different visual functions and that monocular and binocular deprivation have different neural and behavioral consequences. In view of the spectrum of critical windows for different visual functions and for different types of amblyopia, combined with individual variability in these windows, treatment of amblyopia has been increasingly offered to older children and adults...

BACKGROUND: During routine health screenings, pediatricians may note that some infants cannot maintain the prone position with an extended arm support at 6 months. However, little is known regarding the development of full-term infants with this developmental deviation. We investigated the developmental course of infants exhibiting this characteristic. METHODS: We included 2020 full-term infants from a regional center for the Japan Environment and Children's Study...

BACKGROUND: The protozoan Cryptosporidium is a leading cause of diarrhoea morbidity and mortality in children younger than 5 years. However, the true global burden of Cryptosporidium infection in children younger than 5 years might have been underestimated in previous quantifications because it only took account of the acute effects of diarrhoea. We aimed to demonstrate whether there is a causal relation between Cryptosporidium and childhood growth and, if so, to quantify the associated additional burden...

BACKGROUND: Broadly defined learning and coordination disorders (LCDs) are common in the population and have previously been associated with familial social risk factors and male sex. However, comprehensive nationwide studies of these risk factors in LCD subgroups are lacking. Our objective was to assess different LCDs in relation to sex and maternal education, marital status and socioeconomic status based on occupation. METHODS: We conducted a nationwide register-based study...

Gene-by-environment interactions between maternal sensitivity during infancy and child oxytocin receptor gene (OXTR rs53576) and D2 dopamine receptor gene (DRD2 TaqIA, rs1822497) genotypes were explored as predictors of toddlers' well-regulated behavioral and physiological responses to maternal compliance demands. Maternal sensitivity was assessed across a range of mother-child interactions when children were 6 months and 1 year of age (N = 186), and toddler self-regulatory responses were assessed through compliance and vagal withdrawal during a toy clean-up task when children were 2 years of age...

Background: Iron deficiency (ID) in infancy is related to subsequent behavior problems. The effects of micronutrient status in middle childhood are uncertain. Objective: The aim of the study was to examine the associations of micronutrient status biomarkers in middle childhood with externalizing and internalizing behavior problems in adolescence. Methods: We assessed whether ID (ferritin <15 µg/L), anemia (hemoglobin <12.7 g/dL), or blood concentrations of zinc, vitamins A and B-12, and folate at ages 5-12 y were associated with externalizing or internalizing behavior problems in adolescence in 1042 schoolchildren from Bogotá, Colombia...

Non-suicidal self-injury (NSSI) behaviors are self-injurious behaviors inflicted without intending death. Literature has shown the relationship between stressful life events (SLE) and NSSI behaviors. The Strengths and Difficulties Questionnaire-Dysregulation Profile (SDQ-DP) is defined as an index of self-regulatory problems, related to higher risk for suicidal ideation and attempts in adolescents. In this study the relationship between SDQ-DP and NSSI behaviors, mediated by SLE in a clinical sample of children and adolescents is analyzed...

BACKGROUND: The global strategy to control helminthiases (schistosomiasis and soil-transmitted helminthiasis) emphasizes preventive chemotherapy. However, in the absence of access to clean water, improved sanitation, and adequate hygiene, reinfection after treatment can occur rapidly. Integrated approaches might be necessary to sustain the benefits of preventive chemotherapy and make progress toward interruption of helminthiases transmission. OBJECTIVE: The aim of this study was to assess and quantify the effect of an integrated control package that consists of preventive chemotherapy, community-led total sanitation, and health education on soil-transmitted helminthiasis, schistosomiasis, intestinal protozoa infection, and diarrhea in rural Côte d'Ivoire...

Non-heme iron is a vital metabolic cofactor for many core processes of brain development including myelination, dendritogenesis, and neurotransmitter synthesis, and accumulates in the brain with age. However, little is known about development-related differences in brain iron and its association with emerging cognitive abilities during formative years. In this study, we estimated brain iron via R2* relaxometry in children ages 7-16 (N = 57; 38 females) and examined its relation to age-related differences in cognitive ability...

There is no accepted pathology to autism spectrum disorders (ASD) but research suggests the presence of an altered excitatory/inhibitory (E/I) bias in the cerebral cortex. Repetitive transcranial magnetic stimulation (rTMS) offers a non-invasive means of modulating the E/I cortical bias with little in terms of side effects. In this study, 124 high functioning ASD children (IQ > 80, <18 years of age) were recruited and assigned using randomization to either a waitlist group or one of three different number of weekly rTMS sessions (i...

Environmental enteropathy (EE) is characterised by subclinical inflammation and hyperpermeability of the small intestine, hypothesised to be caused by recurrent ingestion of faecal bacteria. It has been suggested that EE may be a contributor to malnutrition and growth delays seen in children living in unsanitary conditions. We measured putative faecal EE markers myeloperoxidase (MPO) (ng/mL) and alpha-1-antitrypsin (AAT) (mg/g) in stool samples collected from 133 children aged 1-5 years in 16 communities enrolled in the WASH for WORMS randomised controlled trial in Timor-Leste...

Quantifying sporadic waterborne infections in community settings can be challenging. Salivary antibody immunoassays are a promising non-invasive tool that can be used in prospective studies of common infections, especially those involving children. This study was conducted in a Massachusetts city, which uses a microbiologically contaminated river as its water source, during summer-early winter periods before and after construction of a new drinking water treatment plant. Monthly saliva samples (7480 samples from 1170 children and 816 adults) were analyzed for immunoglobulin G (IgG) responses to recombinant proteins of Cryptosporidium, one genogroup I (GI) and two GII noroviruses...
