Writing is a complex activity in which lower-level perceptual-motor processes and higher-level cognitive processes continuously interact. Preliminary evidence suggests that writing difficulties are common to children with Neurofibromatosis type 1 (NF1). The aim of this study was to compare the performance of children with and without NF1 in lower (visual perception, motor coordination and visual-motor integration) and higher processes (verbal and performance intelligence, visual spatial organization and visual memory) required for intact writing; and to identify the components that predict the written product's spatial arrangement and content among children with NF1. Thirty children with NF1 (ages 8-16) and 30 typically developing children matched by gender and age were tested, using standardized assessments. Children with NF1 had a significantly inferior performance in comparison to control children, on all tests that measured lower and higher level processes. The cognitive planning skill was found as a predictor of the written product's spatial arrangement. The verbal intelligence predicted the written content level. Results suggest that high level processes underlie the poor quality of writing product in children with NF1. Treatment approaches for children with NF1 must include detailed assessments of cognitive planning and language skills. Copyright © 2014 Elsevier Ltd. All rights reserved.

To compare young children's different intensity physical activity (PA) levels in physical education, recess and exergaming programs. Participants were 140 first and second grade children (73 girls; Meanage= 7.88 years). Beyond the daily 20-minute recess, participants attended 75-minute weekly physical education classes and another 75-minute weekly exergaming classes. Children's PA levels were assessed by ActiGraph GTX3 accelerometers for 3 sessions in the 3 programs. The outcome variables were percentages of time spent in sedentary, light PA and moderate-to-vigorous PA (MVPA). There were significant main effects for program and grade, and an interaction effect for program by grade. Specifically, children's MVPA in exergaming and recess was higher than in physical education. The 2nd-grade children demonstrated lower sedentary behavior and MVPA than the first-grade children during recess; less light PA in both recess and exergaming than first-grade children; and less sedentary behavior but higher MVPA in exergaming than first-grade children. Young children generated higher PA levels in recess and exergaming as compared with physical education. Hence, other school-based PA programs may serve as essential components of a comprehensive school PA program. Implications are provided for educators and health professionals.

Ethnic Stigma, Academic Anxiety, and Intrinsic Motivation in Middle Childhood

Previous research addressing the dynamics of stigma and academics has focused on African-American adolescents and adults. The present study examined stigma awareness, academic anxiety, and intrinsic motivation among 451 young (ages 6–11) and diverse (African-American, Chinese, Dominican, Russian, and European-American) students. Results indicated that ethnic-minority children reported higher stigma awareness than European-American children. For all children, stigma awareness was associated with higher academic anxiety and lower intrinsic motivation. Despite these associations, ethnic-minority children reported higher levels of intrinsic motivation than their European-American peers. A significant portion of the higher intrinsic motivation among Dominican students was associated with their higher levels of school belonging, suggesting that supportive school environments may be important sources of intrinsic motivation among some ethnic-minority children.

A harmonized human biomonitoring pilot study was set up within the frame of the European projects DEMOCOPHES and COPHES. In 17 European countries, biomarkers of some environmental pollutants, including urinary cadmium and hair mercury, were measured in children and their mothers in order to obtain European-wide comparison values on these chemicals. The Belgian participant population consisted in 129 school children (6-11 years) and their mothers (≤ 45 years) living in urban or rural areas of Belgium. The geometric mean levels for mercury in hair were 0.383 μg/g and 0.204 μg/g for respectively mothers and children. Cadmium in mother's and children's urine was detected at a geometric mean concentration of respectively 0.21 and 0.04 μg/l. For both biomarkers, levels measured in the mothers and their child were correlated. While the urinary cadmium levels increased with age, no trend was found for hair mercury content, except the fact that mothers hold higher levels than children. The hair mercury content increased significantly with the number of dental amalgam fillings, explaining partially the higher levels in the mothers by their higher presence rate of these amalgams compared to children. Fish or seafood consumption was the other main parameter determining the mercury levels in hair. No relationship was found between smoking status and cadmium or mercury levels, but the studied population included very few smokers. Urinary cadmium levels were higher in both mothers and children living in urban areas, while for mercury this difference was only significant for children. Our small population showed urinary cadmium and hair mercury levels lower than the health based guidelines suggested by the WHO or the JECFA (Joint FAO/WHO Expert Committee on Food Additives). Only 1% had cadmium level slightly higher than the German HBM-I value (1 μg/l for adults), and 9% exceeded the 1 μg mercury/g hair suggested by the US EPA. Copyright © 2013 Elsevier B.V.

Mycoplasma pneumoniae (MP) is a common cause of community-acquired pneumonia in children, and it has been associated with wheezing. The aim of this study was to examine the serum level of interleukin (IL)-4 and IL-10 in children with Mycoplasma pneumoniae pneumonia (MPP) and to analyse them in relation to the presence of wheezing. The study included 166 children with radiologically confirmed pneumonia. MP infection was confirmed by enzyme-linked immunosorbent assay (ELISA) serum MP-IgM and MP-IgG test and throat swab MP DNA with real-time polymerase chain reaction. Serum levels of IL-4 and IL-10 were measured using ELISA. There was no significant difference in serum level of IL-4 between children with MPP and those with non-MPP. Among children with MPP, we found similar level of IL-4 regardless of the personal and family history of allergy and asthma or the presence of wheezing. A significantly higher level of IL-10 was found in children with MPP than in children with non-MPP (32.92±18.582 vs. 27.01±14.100 pg/ml, p =0.022). Furthermore, wheezing children with MPP had a significantly higher level of IL-10 than children with MPP without wheezing (43.75±26.644 vs. 27.50±10.211 pg/ml, p=0.027). Our results show significantly increased serum level of IL-10 in children with MPP, which was significantly higher in children with wheezing. These findings may suggest a role of IL-10 in the pathogenesis of MPP and in the occurrence of wheezing during acute MP infection. © The Author [2017]. Published by Oxford University Press.

Our goal was to identify individual difference predictors of children's memory and suggestibility for distressing personally experienced events. Specifically, we examined children's and parents' attachment orientations and children's observable levels of distress, as well as other individual difference factors, as predictors of children's memory and suggestibility. Children (N=91) aged 3 to 6years were interviewed about inoculations received at medical clinics. For children whose parents scored as more avoidant, higher distress levels during the inoculations predicted less accuracy, whereas for children whose parents scored as less avoidant, higher distress levels predicted greater accuracy. Children with more rather than less positive representations of parents and older rather than younger children answered memory questions more accurately. Two children provided false reports of child sexual abuse. Implications for theory, research, and practice are discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

Family ecology in early childhood may influence children's activity and participation in daily life. The aim of this study was to describe family functioning, family expectations of their children, family support to their children, and supports for families of young children with cerebral palsy (CP) based on children's gross motor function level. Participants were 398 children with CP (mean age = 44.9 months) and their parents residing in the USA and Canada. Parents completed four measures of family ecology, the Family Environment Scale (FES), Family Expectations of Child (FEC), Family Support to Child (FSC) and Family Support Scale (FSS). The median scores on the FES indicated average to high family functioning and the median score on the FSS indicated that families had helpful family supports. On average, parents reported high expectations of their children on the FEC and strong support to their children on the FSC. On the FES, higher levels of achievement orientation were reported by parents of children in Gross Motor Function Classification System (GMFCS) level II than parents of children in level I, and higher levels of control were reported by parents of children in level I than parents of children in level IV. On the FEC, parents of children with limited gross motor function (level V) reported lower expectations than parents of children at all other levels. Family ecology, including family strengths, expectations, interests, supports and resources, should be discussed when providing interventions and supports for young children with CP and their families. © 2013 John Wiley & Sons Ltd.

During recent decades, the prevalence of metabolic morbidity has increased rapidly in adult Greenlandic Inuit. To what extent this is also reflected in the juvenile Inuit population is unknown. The objective was, therefore, in the comparison with Danish children, to evaluate metabolic profiles in Greenlandic Inuit children from the capital in the southern and from the northern most villages 187 Inuit and 132 Danish children were examined with anthropometrics, pubertal staging, fasting blood samples, and a maximal aerobic test. Both Inuit children living in Nuuk and the northern villages had significantly higher glucose, total cholesterol, apolipoprotein A1 levels, and diastolic blood pressure compared with Danish children after adjustment for differences in adiposity and aerobic fitness levels. The Inuit children living in Nuuk had significantly higher BMI, body fat %, HbA1 c, and significantly lower aerobic fitness and ApoA1 levels than northern living Inuit children. Greenlandic Inuit children had adverse metabolic health profile compared to the Danish children, the differences where more pronounced in Inuit children living in Nuuk. The tendencies toward higher prevalence of diabetes and metabolic morbidity in the adult Greenlandic Inuit population may also be present in the Inuit children population.

We conducted the present study to examine cognitive function and serum heat shock protein 70 levels among children with temporal lobe epilepsy. The Stanford-Binet Intelligence Test was carried out to examine cognitive function in 30 children with temporal lobe epilepsy and 30 controls. Serum heat shock protein 70 levels were determined with an enzyme-linked immunosorbent assay. The epilepsy group had significantly lower cognitive function testing scores and significantly higher serum heat shock protein 70 levels than the control group; there were significant negative correlations between serum heat shock protein 70 levels and short-term memory and composite scores. Children with uncontrolled seizures had significantly lower verbal reasoning scores and significantly higher serum heat shock protein 70 levels than children with controlled seizures. Children with temporal lobe epilepsy have cognitive dysfunction and elevated levels of serum heat shock protein 70, which may be considered a stress biomarker.

While the relationships between physical activity (PA), obesity, and motor skills have been independently examined by previous research, this study explored both independent and combined relationships between children's PA, weight status, and motor skills within a multiple regression analysis. We measured height and weight and calculated body mass index (BMI) z scores for 96 children (3-10 years of age). We measured motor skills using the Movement Assessment Battery for Children-2nd edition (MABC-2), and we measured PA levels through accelerometry. Children with more time in moderate and moderate-to-vigorous PA had higher Total motor skill scores on the MABC-2. Further, children with higher moderate PA levels had higher Balance scores and those with moderate-to-vigorous PA demonstrated higher Aiming and Catching scores. Among children with healthier BMIs, more time spent in PA, regardless of intensity, was related to higher Aiming and Catching scores. Among children with BMI scores suggestive of overweight/obesity, both moderate and moderate-to-vigorous PA were positively related to Balance scores. In conclusion, while BMI z scores were not directly related to motor skills, PA levels were positively related to motor skills, and weight status mediated the relationship between PA and specific components of motor skills.

Background: Polybrominated diphenyl ethers (PBDE), which are used as flame retardants, have been found to be higher in residents of California than of other parts of the United States. Objectives: We aimed to investigate the role of immigration to California on PBDE levels in Latino children. Methods: We compared serum PBDE concentrations in a population of first-generation Mexican-American 7-year-old children (n = 264), who were born and raised in California [Center for Health Analysis of Mothers and Children of Salinas (CHAMACOS) study], with 5-year-old Mexican children (n = 283), who were raised in the states in Mexico where most CHAMACOS mothers had originated (Proyecto Mariposa). Results: On average, PBDE serum concentrations in the California Mexican-American children were three times higher than their mothers’ levels during pregnancy and seven times higher than concentrations in the children living in Mexico. The PBDE serum concentrations were higher in the Mexican-American children regardless of length of time their mother had resided in California or the duration of the child’s breast-feeding. These data suggest that PBDE serum concentrations in these children resulted primarily from postnatal exposure. Conclusions: Latino children living in California have much higher PBDE serum levels than their Mexican counterparts. Given the growing evidence documenting potential health effects of PBDE exposure, the levels in young children noted in this study potentially present a major public health challenge, especially in California. In addition, as PBDEs are being phased out and replaced by other flame retardants, the health consequences of these chemical replacements should be investigated and weighed against their purported fire safety benefits.

A high proportion of circulating immature/naive CD5(+) B cells during early infancy is a risk factor for allergy development. B-cell activating factor (BAFF) is an important cytokine for B-cell maturation. We sought to investigate whether BAFF levels are related to environmental exposures during pregnancy and early childhood and whether BAFF levels are associated with postnatal B-cell maturation and allergic disease. In the FARMFLORA study, including both farming and nonfarming families, we measured BAFF levels in plasma from mothers and their children at birth and at 1, 4, 18, and 36 months of age. Infants' blood samples were also analyzed for B-cell numbers and proportions of CD5(+) and CD27(+) B cells. Allergic disease was clinically evaluated at 18 and 36 months of age. Circulating BAFF levels were maximal at birth, and farmers' children had higher BAFF levels than nonfarmers' children. Higher BAFF levels at birth were positively associated with proportions of CD27(+) memory B cells among farmers' children and inversely related to proportions of CD5(+) immature/naive B cells among nonfarmers' children. Children with allergic disease at 18 months of age had lower cord blood BAFF levels than nonallergic children. At birth, girls had higher BAFF levels and lower proportions of CD5(+) B cells than boys. Farm exposure during pregnancy appears to induce BAFF production in the newborn child, and high neonatal BAFF levels were associated with more accelerated postnatal B-cell maturation, which lend further strength to the role of B cells in the hygiene hypothesis.

To explore the pathogenesis of abnormal behavior in children with obstructive sleep apnea-hypopnea syndrome (OSAHS). The behavioral problems and C-reactive protein were measured in 40 children with OSAHS and 30 children with habitual snoring who underwent overnight Polysomnography, 40 cases of healthy children for the control group. The ratio of abnormal behavior in OSAHS and habitual snoring children was significantly higher than that of the healthy control group, while no significant difference between the two groups. The content of C-reactive protein in OSAHS children (4.24 mg/L) was significantly higher than habitual snoring (2.76 mg/L) and healthy control group (1.27 mg/L); in habitual snoring children C-reactive protein was higher than in healthy control group. The content of serum C-reactive protein in OSAHS children accompanied by abnormal behavior (4.63 mg/L) was significantly higher than that without abnormal behavior (3.23 mg/L). The content of serum C-reactive protein content in habitual snoring children accompanied by abnormal behavior (3.63 mg/L) was significantly higher than that without abnormal behavior (1.76 mg/L). OSAHS and habitual snoring children have more behavior problems. C-reactive protein levels are higher in children with OSAHS and habitual snoring, and the levels of C-reactive protein are related to the abnormal behavior in these children.

The aim of this study was to determine the levels of secretory IgA (SIgA), pH, flow rates, mutans streptococci (MS) and Candida in saliva of children with rampant caries compared to those caries-free. Thirty children (age 62-123 months) were enrolled and divided into two groups: Group I, children with rampant caries, Group II, caries-free children. The average salivary flow rate was measured from the volume yielded within 5 minutes and the pH was determined using a pH-electrode. Measurement of SIgA was performed using an immunoassay kit. The levels of MS and Candida were determined by culture on Mitis-Salivarius Bacitracin agar and Sabouraud dextrose agar. It was found that children with rampant caries presented with significantly higher levels of salivary SIgA, MS and Candida. However, the mean values for salivary flow rates and pH were similar between the groups. The results reveal that children with rampant caries had significantly higher levels of SIgA, MS and Candida in their oral cavities. This finding tends to support the hypothesis that higher levels of salivary SIgA may reflect a past exposure of the host to cariogenic microorganisms.

Trajectories of externalizing behavior from age 2 to age 9: relations with gender, temperament, ethnicity, parenting, and rater.

Miner, Jennifer L; Clarke-Stewart, K Alison

2008-05-01

Trajectories of children's externalizing behavior were examined using multilevel growth curve modeling of data from the NICHD Study of Early Child Care and Youth Development. According to ratings by both mothers and caregivers/teachers when children were 2, 3, 4, 7, and 9 years old, externalizing behavior declined with age. However, mothers rated children as higher in externalizing behavior than did caregivers and teachers. Higher levels of age 9 externalizing behavior were predicted by the following factors: child male gender (for caregiver/teacher reports only), infant difficult temperament (for children with harsh mothers only), harsher maternal attitude toward discipline, higher level of maternal depression (for maternal reports only), and lower level of maternal sensitivity (especially for boys). Caregivers and teachers reported higher levels of externalizing behavior in African American children than in European American children, increasingly so over time; mothers' ratings revealed the reverse. The declining slope of externalizing behavior was predicted by infant difficult temperament for mother reports only. Additional analyses suggested that the association between parenting and externalizing behavior was bidirectional. (PsycINFO Database Record (c) 2008 APA, all rights reserved).

Pediatric lipoprotein curves are based on population-based samples. As obesity, may alter lipoprotein levels, cutoffs not adjusted for body mass index (BMI) are potentially inappropriate. We aimed to develop distinct serum lipid curves based on sex- and BMI-percentiles for children and adolescents. Cross-sectional analysis included all healthy children and adolescents (age range 2-17 years) with available serum lipid concentrations (n = 152,820 of approximately 1.2 million children and adolescents per study year). These children and adolescents were categorized according to sex- and age-stratified BMI-percentiles: 100,375 normal weight (5th-85th percentile), 26,028 overweight (85th-95th percentile) and 26,417 obese (≥95th percentile) individuals. Excluded were individuals with hyperlipidemia, gastrointestinal disease, thyroid disease and lipid-lowering medications. Lambda-Mu-Sigma, smoothed percentile lipid curves were computed. Obese children had a lipid profile pattern throughout childhood and adolescence similar to that of normal weight subjects but with a significant upward shift in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), non-high-density lipoprotein cholesterol (non-HDL-C), and triglycerides (TGs) and a downward shift in high-density lipoprotein-cholesterol (HDL-C). Obese boys had 13 mg/dL higher TC levels (P < 0.001), 11 mg/dL higher LDL-C levels, 15 mg/dL higher non-HDL-C levels, and 5 mg/dL lower HDL-C levels (P < 0.001). Obese girls had 6 mg/dL higher TC levels, 7 mg/dL higher LDL-C levels, 11 mg/dl higher non-HDL-C levels, and 6 mg/dL lower HDL-C levels (P < 0.001). Across a large, nationally representative cohort of children and adolescents, lipoprotein levels were found to vary in relation to weight status. On the basis of these findings, it is suggested that when evaluating the lipid profile in the pediatric population, in addition to sex-based curves, clinical decision making may require consideration of BMI-stratified curves.

2018-06-01

The links between exposure to adverse childhood experiences (ACEs), caregiver insightfulness and emotional availability, and the child's social information processing (SIP) and social behavior were examined in a sample of 15 preschool children enrolled in a Therapeutic Nursery Program (TNP). Children are typically referred to the TNP due to significant delays in their social emotional development that often result in difficulty functioning in typical childcare, home, and community settings. Caregiver insightfulness was measured via an interview with the caregiver. Emotional availability was coded based on observations of caregiver-child interactions. The child's SIP patterns were measured in an interview, and the child's behavior in preschool was assessed by teacher reports. Higher levels of exposure to ACE were hypothesized to be related to lower levels of caregiver emotional availability and insightfulness and to higher levels of the children's perceptual (i.e. SIP) and behavioral maladjustment. It was also hypothesized that caregiver emotional availability and insightfulness would be associated with one another and significantly associated with children's perceptions and behaviors. Caregivers reporting higher levels of exposure exhibited lower levels of insightfulness and emotional availability. No such associations were found between the child's exposure to ACE and the caregivers' perceptions and behaviors. In addition, more insightful caregivers showed higher levels of emotional availability. Finally, children with more emotionally available caregivers showed more competent SIP and social behavior.

Iron deficiency associated with higher blood lead in children living in contaminated environments.

2001-01-01

The evidence that iron deficiency increases lead child exposure is based primarily on animal data and limited human studies, and some of this evidence is contradictory. No studies of iron status and blood lead levels in children have accounted for environmental lead contamination and, therefore, the source of their exposure. Thus, no studies have directly determined whether iron deficiency modifies the relationship of environmental lead and blood lead. In this study, we compared blood lead levels of iron-deficient and iron-replete children living in low, medium, or highly contaminated environments. Measurements of lead in paint, soil, dust, and blood, age of housing, and iron status were collected from 319 children ages 1-5. We developed two lead exposure factors to summarize the correlated exposure variables: Factor 1 summarized all environmental measures, and Factor 2 was weighted for lead loading of house dust. The geometric mean blood lead level was 4.9 microg/dL; 14% exceeded 10 microg/dL. Many of the children were iron deficient (24% with ferritin < 12 ng/dL). Seventeen percent of soil leads exceeded 500 microg/g, and 23% and 63% of interior and exterior paint samples exceeded 5,000 microg/g. The unadjusted geometric mean blood lead level for iron-deficient children was higher by 1 microg/dL; this difference was greater (1.8 microg/dL) after excluding Asians. Blood lead levels were higher for iron-deficient children for each tertile of exposure as estimated by Factors 1 and 2 for non-Asian children. Elevated blood lead among iron-deficient children persisted after adjusting for potential confounders by multivariate regression; the largest difference in blood lead levels between iron-deficient and -replete children, approximately 3 microg/dL, was among those living in the most contaminated environments. Asian children had a paradoxical association of sufficient iron status and higher blood lead level, which warrants further investigation. Improving iron status, along with reducing exposures, may help reduce blood lead levels among most children, especially those living in the most contaminated environments. PMID:11675273

Objectives Human immunodeficiency virus (HIV)-infected children may be at risk for premature cardiovascular disease. We compared levels of biomarkers of vascular dysfunction among HIV-infected children with and without hyperlipidemia to HIV-exposed, uninfected children (HEU) enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS), and determined factors associated with these biomarkers. Design Prospective cohort study Methods Biomarkers of inflammation (C-reactive protein (CRP), interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP1)); coagulant dysfunction (fibrinogen and P-selectin); endothelial dysfunction (soluble intracellular cell adhesion molecule-1 (sICAM), soluble vascular cell adhesion molecule-1 (sVCAM), and E-selectin); and metabolic dysfunction (adiponectin) were measured in 226 HIV-infected and 140 HEU children. Anthropometry, body composition, lipids, glucose, insulin, HIV disease severity, and antiretroviral therapy were recorded. Results The median ages were 12.3 y (HIV-infected) and 10.1 y (HEU). Body mass index (BMI) Z-scores, waist and hip circumference, and percent body fat were lower among HIV-infected. Total and non-HDL cholesterol and triglycerides were higher in HIV-infected children. HIV-infected children had higher MCP-1, fibrinogen, sICAM, and sVCAM levels. In multivariable analyses in the HIV-infected children alone, BMI z-score was associated with higher CRP and fibrinogen, but lower MCP-1 and sVCAM. Unfavorable lipid profiles were positively associated with IL6, MCP1, fibrinogen, and P- and E-selectin, whereas increased HIV viral load was associated with markers of inflammation (MCP1 and CRP) and endothelial dysfunction (sICAM and sVCAM). Conclusions HIV-infected children have higher levels of biomarkers of vascular dysfunction than do HEU children. Risk factors associated with higher biomarkers include unfavorable lipid levels and active HIV replication. PMID:22136114

Ghrelin circulates in blood as acylated (AG) and unacylated (UAG) ghrelin. The physiological role of the two forms is poorly understood, in particular in childhood. Aim of the study was to evaluate the AG and UAG levels in obese and normal weight (NW) children, pre-pubertal and pubertal, and their relationship with insulin, leptin and adiponectin levels. A population based study in which AG, UAG, leptin, adiponectin, glucose, insulin, testosterone or estradiol levels, insulinemic indexes were evaluated in 82 NW and 58 obese (OB) children. Both ghrelin forms in NW were higher (AG, p<0.02; UAG, p<0.0001) than in OB subjects, with similar ratio AG/UAG . While no differences were observed for gender, puberty AG (p<0.01) and UAG (p<0.0001) levels were higher in pre-pubertal than pubertal NW and OB subjects. Adiponectin levels in NW subjects were higher (p<0.001), while leptin and insulin levels were lower (p<0.0001) than in OB subjects. NW children showed homeostasis model assessment (HOMA) and HOMAβ indices lower than OB children (p<0.0001) with a higher a quantitative insulin sensitivity check index (p<0.0001). AG and UAG levels correlated to each other (p<0.0001), each showing a negative correlation to age, height, weight and body mass index. Both forms, but more strongly UAG, correlated with adiponectin, leptin, and insulin. OB children show lower levels of both AG and UAG when compared to NW subjects, with lower levels during puberty. These results demonstrate a peculiar strong relationship between UAG levels and metabolic parameters in the pediatric population, suggesting a role for UAG in metabolic functions.

Findings are presented on a study of 40 gay father families created through surrogacy and a comparison group of 55 lesbian mother families created through donor insemination with a child aged 3-9 years. Standardized interview, observational and questionnaire measures of stigmatization, quality of parent-child relationships, and children's adjustment were administered to parents, children, and teachers. Children in both family types showed high levels of adjustment with lower levels of children's internalizing problems reported by gay fathers. Irrespective of family type, children whose parents perceived greater stigmatization and children who experienced higher levels of negative parenting showed higher levels of parent-reported externalizing problems. The findings contribute to theoretical understanding of the role of family structure and family processes in child adjustment. © 2017 The Authors.

2011-01-01

Previous research addressing the dynamics of stigma and academics has focused on African American adolescents and adults. The present study examined stigma awareness, academic anxiety, and intrinsic motivation among 451 young (ages 6-11) and diverse (African American, Chinese, Dominican, Russian, and European American) students. Results indicated that ethnic-minority children reported higher stigma awareness than European American children. For all children, stigma awareness was associated with higher academic anxiety and lower intrinsic motivation. Despite these associations, ethnic-minority children reported higher levels of intrinsic motivation than their European American peers. A significant portion of the higher intrinsic motivation among Dominican students was associated with their higher levels of school belonging, suggesting that supportive school environments may be important sources of intrinsic motivation among some ethnic-minority children. © 2011 The Authors.

Does God Make it Real? Children's Belief in Religious Stories from the Judeo-Christian Tradition

PubMed Central

Vaden, Victoria Cox; Woolley, Jacqueline D.

2010-01-01

Four- to 6-year-old children heard religious or non-religious stories and were questioned about their belief in the reality status of the story characters and events. Children had low to moderate levels of belief in the story characters and events. Children in the religious story condition had higher levels of belief in the reality of the story characters and events than did children in the non-religious condition; this relationship strengthened with age. Children who used God as an explanation for the events showed higher levels of belief in the factuality of those events. Story familiarity and family religiosity also affected children's responses. We conclude that God's involvement in a story influences children's belief in the reality of the characters and events in that story. PMID:21466542

Characteristics associated with low socioeconomic status neighbourhoods may put children at risk for unique chronic stressors that affect cortisol levels. This research sought to explore whether neighbourhood stressor exposure affected serum cortisol levels among children. A total of 148 African and European-American children with an average age of 8.28 years participated in a longitudinal study evaluating ethnic differences in body composition and disease risk. Five waves of data were included in analyses. Mixed modelling was used to explore neighbourhood stressors, which was a composite index of five items for zip code level poverty and physical disorder, and serum cortisol outcomes for the full sample, by race/ethnicity and gender. Adjustments were made for individual level correlates age, pubertal status, gender and total fat mass. Neighborhood disorder was predictive of lower serum cortisol levels among African-American children (p<0.05), such that higher neighbourhood stressor exposure resulted in lower serum cortisol over time compared with individuals in socially ordered neighbourhoods. Neighbourhood disorder was marginally significant and predictive of higher serum cortisol among European-American children (p<0.10). Transition to a higher pubertal status, nested in age was also predictive of lower serum cortisol levels (p<0.01) among European-American children. Children who are exposed to negative socioenvironmental climates over time are more likely to have altered serum cortisol levels. This may be an adaptive mechanism to cope with stress; however, disrupted cortisol levels may have negative effects on general physical and mental health.

Children with constipation are advised frequently to increase their activity levels, fluids and fibre intake. The aim of this study was to examine the prevalence of constipation symptoms in a group of schoolchildren while concurrently assessing their activity levels and fluid and fibre intakes. Eighty-four pre-adolescent children aged 7-10 years were recruited. All children completed a bowel function diary, an activity diary and a weighed food inventory for seven consecutive days. Of the children, 33 percent were found to experience constipation symptoms. Fluid and fibre intakes were higher in the children who did not experience constipation symptoms, but the results were not significant. Physical activity levels were found to be significantly higher in the children reporting constipation symptoms, with the most active children reporting low water intakes. This study has highlighted that constipation symptoms are a prevalent problem in children not seeking medical treatment.

A socio-ecological model for unintentional injuries in minorities: a case study of Arab Israeli children.

PubMed

Baron-Epel, Orna; Ivancovsky, Michal

2015-01-01

Minority children have often been reported to be at high risk of injury. The higher levels of reported unintentional injuries among Arab children compared to Jewish children in Israel are mainly due to pedestrian traffic crashes, falls and burns. Arab children aged 1-4 years have a higher relative risk of injury compared to Jews. We suggest a socio-ecological model to explain these differences in risk based on individual, interpersonal, community and societal ecological levels of society. Each level is divided into social and physical environments and behaviour. Two main factors may contribute to the high rates of injury among Arab children: the quality of the physical environment in which the children live and play and the levels of child supervision. Socio-economic status may contribute to these differences at all ecological levels of society. This approach could be useful for researchers and practitioners to analyse similar issues in other communities and help develop appropriate interventions.

Viewing preferences, symptoms of psychological trauma, and violent behaviors among children who watch television.

1998-10-01

To examine the extent to which children's television-viewing practices are associated with symptoms of psychological trauma and aggressive behaviors. The following three hypotheses were tested: (1) children who report watching greater amounts of television per day will report higher levels of trauma symptoms than children who report lesser amounts of television viewing; (2) children who report watching greater amounts of television per day will report higher levels of violent behaviors than children who report watching lesser amounts of television per day; and (3) children who report a preference for action and fighting programs will report higher levels of violent behaviors than children who report a preference for other types of television programs. The study used a survey design in which an anonymous self-report questionnaire was administered to students in grades 3 through 8 in 11 Ohio public schools during the 1995-1996 school year (N = 2,245). All three hypotheses were supported. Heavy television viewing by children may indicate the presence of problems such as depression, anxiety, and violent behaviors; such viewing should be screened for by psychiatrists and other mental health professionals working with children.

Irisin and oxytocin can affect energy homeostasis and it has been suggested that they may play an important role in reducing obesity and diabetes. In this study, we aimed to determine the relationship between metabolic parameters (including irisin and oxytocin levels) and anthropometric parameters in obese children. Ninety obese children (mean age, 13.85±1.63 years) and 30 healthy controls (mean age, 14.32±1.58 years) were enrolled in this study. Anthropometric and laboratory parameters (glucose, insulin, lipid, oxytocin, and irisin levels) were analyzed. The serum irisin and oxytocin levels were measured by enzyme-linked immunosorbent assay. Bioelectrical impedance was used to determine body composition. Irisin level was higher in the patients than in the controls (p=0.018), and this higher irisin level was correlated with increased systolic blood pressure, body mass index, waist/hip ratio, fat percentage, fat mass, glucose level, insulin level, and homeostasis model assessment of insulin resistance. Serum oxytocin level was significantly decreased in obese children compared to the controls (p=0.049). Also, among the 60 obese patients, oxytocin level was significantly lower in patients with than in those without metabolic syndrome (8.65±2.69 vs. 10.87±5.93 ng/L, respectively), while irisin levels were comparable (p=0.049 and p=0.104, respectively). There were no statistically significant relationships between oxytocin or irisin levels and lipid levels (p>0.05). Obese children had significantly higher irisin levels than the healthy controls. Additionally, this study shows for the first time that oxytocin level is significantly lower in obese compared with non-obese children and also lower in obese children with metabolic syndrome compared to those without.

Mental health problems and parental anxiety in children with epilepsy were investigated. Parents of 83 children with epilepsy and 172 healthy children were asked to complete Strengths and Difficulties Questionnaire for their children and State-Trait Anxiety Inventory for themselves. In those with epilepsy, 39.8% (n: 33) were girls, 60.2% (n: 50) were boys and their mean age was 9.34 ± 3.99 years. Control group was more successful in school (p < 0.001). Emotional problems score in children with epilepsy was higher than control group (p < 0.001). Case group's behavior problems and attention deficit hyperactivity scores were higher (p < 0.001, p=0.009 respectively). Prosocial behavior scores of the control group were significantly higher (p=0.004). State (p=0.001) and trait (p=0.001) anxiety levels of parents of children with epilepsy were higher. Children with epilepsy have more neuro-behavioral problems; and their parents have greater anxiety levels. Physicians should be in contact with children with epilepsy for the psychological health of the family besides seizure control.

Rice, Kelly R; Trost, Stewart G

2014-01-01

To objectively measure the physical activity (PA) levels of children attending family day care programs. A total of 114 children from 47 family day care centers wore an accelerometer for the duration of their time in care. Time in moderate-to-vigorous PA (MVPA) and total PA was calculated using previously validated cut points. Children accumulated 5.8 ± 3.2 minutes of MVPA and 10.4 ± 4.4 minutes of total PA per hour of attendance. Boys exhibited significantly higher levels of PA than girls. Among healthy weight children, 4- and 5-year-olds exhibited significantly higher levels of PA than 2- and 3-year-olds. Overweight and obese 4- and 5-year-olds exhibited significantly lower levels of PA than their healthy weight counterparts. Children attending family day care participate in low levels of PA during the child care day. The results highlight the need for effective programs to promote PA in family day care.

2015-06-01

We examined links between sharing, respect for moral others, and sympathy in an ethnically diverse sample of 7- and 15-year-olds (N = 146). Sharing was assessed through children's allocation of resources in the dictator game. Children reported their respect towards hypothetical characters performing moral acts. Sympathy was evaluated via caregiver and child reports. Respect and caregiver-reported sympathy interacted in predicting sharing: Higher levels of respect were associated with higher levels of sharing for children with low, but not medium or high, levels of sympathy. The motivational components of other-oriented respect may compensate for low levels of sympathetic concern in the promotion of sharing. © 2015 The British Psychological Society.

2015-01-01

To assess the plasma Pentraxin 3 (PTX3) concentrations in obese children and to investigate the relationship between PTX3 levels and metabolic syndrome (MS) components. Seventy-seven obese patients aged 10-16 y (38 girls, 39 boys) were included in the study. PTX3 levels were compared between the groups with or without MS. In addition, PTX3 was analysed separately by subgroups according to the presence of specific MS components. Plasma PTX3 concentrations were significantly higher in obese children and adolescents with metabolic syndrome than in those without MS (2.1 ± 1.2 ng/ml and 1.4 ± 0.9 ng/ml respectively; P = 0.02). Patients with low HDL levels (<40 mg/dl) had higher plasma PTX3 concentrations than those with normal HDL levels (P = 0.05). Similarly, those who had high triglyceride levels (≥ 150 mg/dl) had higher PTX3 levels (P = 0.01). PTX3 levels were negatively correlated with HDL cholesterol (r = -0.32, P = 0.003) among all patients. PTX3 levels are higher in obese children and adolescents with metabolic syndrome than in those without MS. Thus, PTX3 levels might be a useful biomarker for children and adolescents with metabolic syndrome, dyslipidemia, and cardiovascular risks.

Objective To assess associations of protective workplace and home practices to pesticide exposure levels. Methods Using data from orchard workers in the Yakima Valley, Washington, we examined associations of workplace and home protective practices to (1) urinary metabolite concentrations of dimethylthiophosphate (DMTP) in adults and children aged 2–6; and (2) azinphos-methyl levels in house and vehicle dust. Results Data were from 95 orchard workers and 94 children. Contrary to expectation, adult farm workers who wore boots or washed hands using hand sanitizer had higher concentrations of DMTP than those who did not. Children who attended daycare had higher DMTP concentrations than children who did not. Conclusions Few workplace or home practices were associated with pesticide exposure levels; workers who used hand sanitizer had higher concentrations of DMTP, as did children who attended daycare.

Interstitial lung disease is common in patients with sickle cell anemia (SCA). Fibrocytes are circulating cells implicated in the pathogenesis of pulmonary fibrosis and airway remodeling in asthma. In this study, we tested the hypotheses that fibrocyte levels are: (1) increased in children with SCA compared to healthy controls, and (2) associated with pulmonary disease. Cross-sectional cohort study of children with SCA who participated in the Sleep Asthma Cohort Study. Fibrocyte levels were obtained from 45 children with SCA and 24 controls. Mean age of SCA cases was 14 years and 53% were female. In children with SCA, levels of circulating fibrocytes were greater than controls (P < 0.01). The fibrocytes expressed a hierarchy of chemokine receptors, with CXCR4 expressed on the majority of cells and CCR2 and CCR7 expressed on a smaller subset. Almost half of fibrocytes demonstrated α-smooth muscle actin activation. Increased fibrocyte levels were associated with a higher reticulocyte count (P = 0.03) and older age (P = 0.048) in children with SCA. However, children with increased levels of fibrocytes were not more likely to have asthma or lower percent predicted forced expiratory volume in 1 sec/forced vital capacity (FEV1 /FVC) or FEV1 than those with lower fibrocyte levels. Higher levels of fibrocytes in children with SCA compared to controls may be due to hemolysis. Longitudinal studies may be able to better assess the relationship between fibrocyte level and pulmonary dysfunction. © 2015 Wiley Periodicals, Inc.

The goal of this study was to explore relations between teacher characteristics (i.e., competence and wellbeing); social classroom relationships (i.e., teacher-child and peer interactions); and children's social, emotional, and behavioral classroom adjustment. These relations were explored at both the individual and classroom levels among 414 children with emotional and behavioral disorders placed in special education. Two models were specified. In the first model, children's classroom adjustment was regressed on social relationships and teacher characteristics. In the second model, reversed links were examined by regressing teacher characteristics on social relationships and children's adjustment. Results of model 1 showed that, at the individual level, better social and emotional adjustment of children was predicted by higher levels of teacher-child closeness and better behavioral adjustment was predicted by both positive teacher-child and peer interactions. At the classroom level, positive social relationships were predicted by higher levels of teacher competence, which in turn were associated with lower classroom levels of social problems. Higher levels of teacher wellbeing were directly associated with classroom adaptive and maladaptive child outcomes. Results of model 2 showed that, at the individual and classroom levels, only the emotional and behavioral problems of children predicted social classroom relationships. At the classroom level, teacher competence was best predicted by positive teacher-child relationships and teacher wellbeing was best predicted by classroom levels of prosocial behavior. We discuss the importance of positive teacher-child and peer interactions for children placed in special education and suggest ways of improving classroom processes by targeting teacher competence.

Personal carbon monoxide exposures of preschool children in Helsinki, Finland: levels and determinants

NASA Astrophysics Data System (ADS)

Alm, S.; Mukala, K.; Jantunen, M. J.

Personal CO exposures of 194 preschool children were measured with personal exposure monitors during a 24 week sampling period from fall 1990 to spring 1991 in Helsinki, Finland. Arithmetic mean of the maximum 1 and 8 h exposure levels were 6.0 and 3.3 mg m -3. The then Finnish ambient air quality guideline values for 1/8 h maximum CO level (30/10 mg m -3) were exceeded in 2/4% of the children's daily maximum 1/8 h exposure levels. Gas stove at home, parents, especially mother, smoking in the home, and living in high rise buildings — reflecting higher local population and traffic density — increased the children's CO exposures. The presence of a fireplace in the home was associated with decreased CO exposures. Father's high education reduced the children's CO exposure while mother's education level had no significant effect. The peak (15 min) exposure levels of the children commuting to day care center by car or bus were higher than those of the children who walked or came by bike.

Behavior Problems in Elementary School among Low-Income Males: The Role of Teacher-Child Relationships

O’Connor, Erin Eileen; Supplee, Lauren

2017-01-01

The present study identified trajectories of teacher-child relationship conflict and closeness from first through sixth grades, and associations between these trajectories and externalizing and internalizing behaviors at age 11 among low-income, urban males (N = 262). There were three main findings. Nagin cluster analyses indicated five trajectories for conflict with all children evidencing increases in conflict, and four trajectories for closeness with all children demonstrating decreases in closeness. Trajectories with higher levels of conflict and lower levels of closeness were associated with higher levels of externalizing and internalizing behavior problems at age 11. Moreover, conflictual teacher-child relationships exacerbated the effects of externalizing and internalizing behavior problems in early childhood; children with conflictual teacher-child relationships had higher levels of behavior problems in middle childhood relative to children with low conflictual teacher-child relationships. Implications of targeting teacher-child relationships as interventions to help prevent behavior problems are discussed. PMID:29170565

A bi-directional relationship exists between asthma and obstructive sleep apnea (OSA) in which presence of one is associated with increased prevalence and severity of the other. Our objective was to determine whether OSA accounted for differences in airway and systemic inflammation in asthmatic children and whether inflammation was associated with asthma control. We hypothesized that greater severity of SDB would correlate with increased upper airway and systemic inflammation and result in reduced asthma control. Non-obese children aged 4-12 years with persistent asthma, with or without OSA were recruited. Asthma control was measured with the Childhood Asthma Control Test. Children underwent polysomnography and blood sampling, and children with OSA underwent clinically indicated adenotonsillectomy. Tonsils and sera were analyzed for 11 cytokines. Twenty-seven children (20 with OSA, seven without OSA) participated, mean age 7.9 years, 55.6% female, 92.6% African American. Levels did not differ for any cytokine between children with and without OSA. Lower nadir oxygen saturation was associated with higher levels of tonsil TNF-α (P < 0.001) and IL-10 (P < 0.05). Higher REM-related apnea-hypopnea index was associated with higher levels of tonsil TNF-α (P < 0.05). Children with uncontrolled asthma had significantly higher levels of serum IL-10, IL-13, and TNF-α, and tonsil TNF-α (all P < 0.05) than well-controlled asthmatic children. There was no association between OSA, or any polysomnography variable, and asthma control. Despite the presence of OSA-associated airway inflammation, and asthma control-associated airway and systemic inflammation, OSA was not related to level of asthma control in this non-obese, largely minority, low income sample. © 2018 Wiley Periodicals, Inc.

Objective To examine and compare the family environment of preschool- and school-age children with cochlear implants and assess its influence on children’s executive function and spoken language skills. Study Design Retrospective between-subjects design. Setting Outpatient research laboratory. Patients Prelingually deaf children with cochlear implants and no additional disabilities, and their families. Intervention(s) Cochlear implantation and speech-language therapy. Main Outcome Measures Parents completed the Family Environment Scale and the Behavior Rating Inventory of Executive Function (or the preschool version). Children were tested using the Peabody Picture Vocabulary Test-4 and either the Preschool Language Scales-4 or the Clinical Evaluation of Language Fundamentals–4. Results The family environments of children with cochlear implants differed from normative data obtained from hearing children, but average scores were within one standard deviation of norms on all subscales. Families of school-age children reported higher levels of control than those of preschool-age children. Preschool-age children had fewer problems with emotional control when families reported higher levels of support and lower levels of conflict. School-age children had fewer problems with inhibition but more problems with shifting of attention when families reported lower levels of conflict. School-age children’s receptive vocabularies were enhanced by families with lower levels of control and higher levels of organization. Conclusions Family environment and its relation to language skills and executive function development differed across the age groups in this sample of children with cochlear implants. Because family dynamics is one developmental/environmental factor that can be altered with therapy and education, the present results have important clinical implications for family-based interventions for deaf children with cochlear implants.

The aim of this study was to investigate the alterations in the oxidant/antioxidant status in obese children with and without metabolic syndrome (MetS). We recruited 25 Caucasian obese children with MetS, 30 Caucasian children with simple obesity and a control group of 30 Caucasian children. We performed diacron-reactive oxygen metabolites (d-ROMs) test and biological antioxidant potential (BAP) test in order to evaluate the oxidant-antioxidant status in recruited patients. d-ROM level was significantly higher in obese children with and without MetS (p = 0.005). The total antioxidant capacity (BAP level) was reduced in MetS and noMetS children compared to controls (p = 0.009). The subjects without MetS had higher d-ROMs test and lower BAP/d-ROMs ratio than subjects with MetS (although not significant). The ratio BAP/d-ROMs was higher in controls than noMetS and MetS children (p < 0.0001). d-ROM level was higher in prepubertal subjects with MetS than pubertal ones (p = 0.03). A direct correlation was found between d-ROM levels and BMI SDS (p = 0.0005), while an inverse correlation was found between BAP and BMI SDS (p = 0.004) and BAP/d-ROMs and BMI SDS (p = 0.0001). This result confirms that fat accumulation plays a key role in the pathogenesis of systemic oxidative stress already during pediatric age. Copyright © 2012 S. Karger AG, Basel.

To identify immune factors present during the acute rash phase of measles and associations with outcome and human immunodeficiency virus type 1 (HIV-1) coinfection, we measured the plasma levels of 22 cytokines and chemokines in Zambian children hospitalized with measles (n = 148) and control children (n = 44). Children with measles had higher levels of innate cytokines tumor necrosis factor (TNF) α, interleukin 1β (IL-1β), interleukin 18, and interleukin 6; chemokines CCL2, CCL4, CCL11, CCL22, CXCL8, and CXCL10; and T-cell cytokines interferon γ, and interleukin 2, 10, and 17. Children who died in the hospital had higher levels of TNF-α, IL-1β, interleukin 12p70; CCL2, CCL4, CCL13, CCL17, CXCL8, CXCL10; and interleukin 2 and interferon γ than children who survived, and lower levels of interleukin 4. Children coinfected with HIV-1 had higher levels of TNF-α and IL-1β than HIV-uninfected children with measles, and lower levels of interleukin 4 and 5. Therefore, acute measles was characterized by activation of macrophages and T cells producing type 1, but not type 2, cytokines, which was more pronounced in fatal disease. © The Author 2017.

The purpose of this study was to examine the impact of parenting styles on emotional intelligence of HIV-affected children in Thailand. This study uses data from 205 HIV-affected children in northern and northeastern Thailand. Correlation and regression analyses were used to examine the predictors of emotional intelligence. Children reporting higher levels of stress reported less caring parenting style (Standardized beta [B] = −0.18, p=0.050). Children with higher self-esteem were also more likely to perceive their parents as caring (B = 0.48, p = 0.002). Children who scored lower on their self-esteem reported their parents to be more overprotective (B = −0.30, p = 0.030), and children reporting higher levels of stress reported their parents to be more overprotective (B = 0.12, p = 0.010). Children reporting caring parenting style were significantly more likely to report higher emotional intelligence (B = 0.66, p = 0.001). Parenting styles play an important role in the emotional intelligence. Identifying and testing interventions to help parents improve their parenting styles, while helping their HIV-affected children cope with stress and self-esteem, are essential in promoting mental health of HIV-affected children in Thailand.

To evaluate the effects of diarrhea on appetite among Peruvian children age 12 to 71 months and to assess whether elevated plasma levels of peptide YY, tumor necrosis factor (TNF)-alpha, and interleukin (IL)-1beta contribute to anorexia in this population. A total of 46 Peruvian children with diarrhea and 46 healthy controls underwent an observed feeding trial that was repeated when cases were healthy. Blood samples were obtained from 30 cases and 30 controls at the first trial and from 30 cases at the second trial and assayed for peptide YY, TNF-alpha, and IL-1beta. In the cases, mean consumption was less when sick than when healthy. The mean plasma level of peptide YY was higher for cases than controls and higher for cases when sick than when healthy. TNF-alpha levels were higher in cases than controls at visit 1 and also higher in cases when sick than when healthy. There were no differences in IL-1beta levels between cases and controls or between cases when sick and healthy. Peptide YY levels in children with diarrhea correlated with the likelihood of them eating less when sick than when healthy. Elevated serum peptide YY may be a mechanism for anorexia in children with diarrhea.

To study the serum contents of the PAEs of obese children at the ages of 10 to 12 years, in order to estimate the harm of PAEs on obese children. The contents of three kinds PAEs(DEP, DBP and DEHP) in the serum for two groups of children, including 36 obese children and 36 normal weight children, were determined by the reversed phase high performance liquid chromatography (RP-HPLC) method And the average measure value of three kind PAEs between two groups of children were analysed. The median serum levels of PAEs were 0.0032 (DEP), 0.1649 (DBP) and 0.1680 (DEHP) in obese children. And the serum levels of PAEs were 0.0026 (DEP), 0.0359 (DBP) and 0.1063 (DEHP) in normal weight children. The differences of average measure value of DBP and DEHP in three kind PAEs between two groups of children were significant (P < 0.01). The amounts of obese children in high level were more than those of normal weight children, and the constitution ratios in three kinds of PAEs of obese children were higher than those of normal weight children. The differences between two groups of children were significant (P < 0.01). The average levels of DBP and DEHP in serum of obese children were more than those of serum of normal weight children. The amounts of obese children were higher than those of normal weight children in high level content of three kinds of PAEs.

Cortisol levels were compared in children born preterm at extremely low gestational age (ELGA; 24–28 weeks), very low gestational age (VLGA; 29–32 weeks), and full-term in response to cognitive assessment at 18 months corrected age (CA). Further, we investigated the relationship between maternal interactive behaviors and child internalizing behaviors (rated by the mother) in relation to child cortisol levels. ELGA children had higher “pretest” cortisol levels and a different pattern of cortisol response to cognitive assessment compared to VLGA and full-terms. Higher cortisol levels in ELGA, but not full-term, children were associated with less optimal mother interactive behavior. Moreover, the pattern of cortisol change was related to internalizing behaviors among ELGA, and to a lesser degree VLGA children. In conclusion, our findings suggest altered programming of the hypothalamic-pituitary-adrenal (HPA) axis in preterm children, as well as their greater sensitivity to environmental context such as maternal interactive behavior.

To establish baseline noninvasive carboxyhemoglobin (COHb) levels in children and determine the influence of exposure to environmental sources of carbon monoxide (CO), especially environmental tobacco smoke, on such levels. Second-hand smoking may be a risk factor for adverse outcomes following anesthesia and surgery in children (1) and may potentially be preventable. Parents and their children between the ages of 1-12 were enrolled on the day of elective surgery. The preoperative COHb levels of the children were assessed noninvasively using a CO-Oximeter (Radical-7 Rainbow SET Pulse CO-Oximeter; Masimo, Irvine, CA, USA). The parents were asked to complete an environmental air-quality questionnaire. The COHb levels were tabulated and correlated with responses to the survey in aggregate analysis. Statistical analyses were performed using the nonparametric Mann-Whitney and Kruskal-Wallis tests. P < 0.05 was statistically significant. Two hundred children with their parents were enrolled. Children exposed to parental smoking had higher COHb levels than the children of nonsmoking controls. Higher COHb values were seen in the youngest children, ages 1-2, exposed to parental cigarette smoke. However, these trends did not reach statistical significance, and confidence intervals were wide. This study revealed interesting trends of COHb levels in children presenting for anesthesia and surgery. However, the COHb levels measured in our patients were close to the error margin of the device used in our study. An expected improvement in measurement technology may allow screening children for potential pulmonary perioperative risk factors in the future.

Autism is a pervasive neurodevelopmental disorder,thought to be caused by a combination of genetic heritability and environmental risk factors. Some autistic-like traits have been reported in mothers of autistic children. We hypothesized that dysregulation of oxytocin (OXT), Arg-vasopressin (AVP) and sex hormones, found in autistic children, may also exist in their mothers. We determined plasma levels of OXT (40 in autism vs. 26 in control group), AVP (40 vs. 17) and sex hormones (61 vs. 47) in mothers of autistic and normal children by enzyme immunoassay and radioimmunoassay, respectively and investigated their relationships with the children's autistic behavior scores (Childhood Autism Rating Scale (CARS) and Autism Behavior Checklist (ABC)). Significantly lower plasma concentrations of OXT (p<0.001) and AVP (p<0.001), as well as a higher level of plasma testosterone (p<0.05), were found in mothers of autistic children vs. those of control. The children's autistic behavior scores were negatively associated with maternal plasma levels of OXT and AVP. These results suggest that dysregulation of OXT, AVP and/or testosterone systems exist in mothers of autistic children, which may impact children's susceptibility to autism.

To review the incident status of childhood type 1 diabetes mellitus hospitalized in the Children's Hospital of Zhejiang University School of Medicine from 1999 to 2009 and to explore the clinical value of IL-10 in diabetic ketoacidosis. The clinical data of 263 children with type 1 diabetes mellitus hospitalized in the Children's Hospital of Zhejiang University School of Medicine from January 1999 to February 2009 were retrospectively reviewed. Serum lipid levels were measured in 48 children with type 1 diabetes mellitus and in 24 healthy children. The diabetic children were classified into two subgroups, with or without ketoacidosis. Serum lipid and cytokines levels were compared. Childhood type 1 diabetes mellitus was common in females (56.3%). The peak incident age of the disease was between 6 and 11.9 years. Diabetic ketoacidosis was as the presenting symptom for the first visit in 86 cases (32.7%). The levels of serum lipid, blood glucose and HbA1c in diabetic children with ketoacidosis were significantly higher than those without ketoacidosis (P<0.05). Logistic analysis demonstrated that the increased levels of blood glucose, serum lipid and HbA1c were risk factors for diabetic ketoacidosis. The level of serum IL-10 in diabetic children with ketoacidosis was significantly higher than that in patients without ketoacidosis (P<0.01), while there were no differences in serum levels IL-2, IL4, IL-6, TNF-α and IFN-γ between them. Serum levels IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ in diabetic children were significantly higher than those in healthy children (P<0.01). Ketoacidosis is a common acute complication of type 1 diabetes mellitus. The disorders of glucose and lipid metabolism are the risk factors for ketoacidosis in diabetic children. IL-10 may be a sensitive index of diabetic ketoacidosis in children with type 1 diabetes mellitus.

Arsenic exposure in children is a public health concern but is understudied in relation to the predictors, and effects of low-level exposure. We examined the extent and dietary predictors of exposure to inorganic arsenic in 5–8 year old children from Montevideo, Uruguay. Children were recruited at school; 357 were enrolled, 328 collected morning urine samples, and 317 had two 24-hour dietary recalls. Urinary arsenic metabolites, i.e. inorganic arsenic (iAs), methylarsonic acid (MMA), and dimethylarsinic acid (DMA), were measured using high-performance liquid chromatography with hydride generation and inductively coupled plasma mass spectrometry (HPLC-HG-ICP-MS), and the sum concentration (U-As) used for exposure assessment. Proportions of arsenic metabolites (%iAs, %MMA and %DMA) in urine were modelled in OLS regressions as functions of food groups, dietary patterns, nutrient intake, and nutritional status. Exposure to arsenic was low (median U-As: 9.9 µg/L) and household water (water As: median 0.45 µg/L) was not a major contributor to exposure. Children with higher consumption of rice had higher U-As but lower %iAs, %MMA, and higher %DMA. Children with higher meat consumption had lower %iAs and higher %DMA. Higher scores on ”nutrient dense” dietary pattern were related to lower %iAs and %MMA, and higher %DMA. Higher intake of dietary folate was associated with lower %MMA and higher %DMA. Overweight children had lower %MMA and higher %DMA than normal-weight children. In summary, rice was an important predictor of exposure to inorganic arsenic and DMA. Higher meat and folate consumption, diet rich in green leafy and red-orange vegetables and eggs, and higher BMI contributed to higher arsenic methylation capacity. PMID:26828624

Autism spectrum disorder (ASD) is defined by impairments of social interaction and the presence of obsessive behaviors. The "twin" nonapeptides oxytocin (OXT) and arginine-vasopressin (AVP) are known to play regulatory roles in social behaviors. However, the plasma levels and behavioral relevance of OXT and AVP in children with ASD have seldom been investigated. It is also unknown whether their mothers have abnormal plasma peptide levels. Here, using well-established methods of neuropeptide measurement and a relatively large sample size, we determined the plasma levels of the two neuropeptides in 85 normal children, 84 children with ASD, and 31 mothers from each group of children. As expected, children with ASD had lower plasma OXT levels than gender-matched controls (P = 0.028). No such difference was found for plasma AVP concentrations. Correlation analysis showed that ASD children with higher plasma OXT concentrations tended to have less impairment of verbal communication (Rho = -0.22, P = 0.076), while those with higher plasma AVP levels tended to have lower levels of repetitive use of objects (Rho = -0.231, P = 0.079). Unlike the findings in children, maternal plasma OXT levels showed no group difference. However, plasma AVP levels in the mothers of ASD children tended to be lower than in the mothers of normal children (P = 0.072). In conclusion, our results suggest that the OXT system is dysregulated in children with ASD, and that OXT and AVP levels in plasma seem to be associated with specific autistic symptoms. The plasma levels of OXT or AVP in mothers and their ASD children did not seem to change in the same direction.

Finnish and Russian Karelian children have a highly contrasting occurrence of asthma and allergy. In these two environments, we studied associations between total serum immunoglobulin E (IgE) with methylation levels in cluster of differentiation 14 (CD14). Five hundred Finnish and Russian Karelian children were included in four groups: Finnish children with high IgE (n = 126) and low IgE (n = 124) as well as Russian children with high IgE (n = 125) and low IgE (n = 125). DNA was extracted from whole blood cells and pyrosequenced. Three CpG sites were selected in the promoter region of CD14. Methylation levels in two of the three CpG sites were higher in the Finnish compared to Russian Karelian children. In the promoter area of CD14, the Finnish compared to Russian children with low IgE had a significant (p < 0.0001) increase in methylation levels at the Amp5Site 2. Likewise, the Finnish compared to Russian children with high IgE had a significant (p = 0.003) increase in methylation levels at the Amp5Site 3. In Russian children with low vs. high IgE, there were significant differences in methylation levels, but this was not the case on the Finnish side. In the regression analysis, adding the methylation variation of CD14 to the model did not explain the higher asthma and allergy risk in the Finnish children. The methylation levels in the promoter region of CD14 gene were higher in the Finnish compared to Russian Karelian children. However, the methylation variation of this candidate gene did not explain the asthma and allergy contrast between these two areas. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Using a multisite community sample of 585 children, this study examined how protective and vulnerability factors alter trajectories of teacher-reported externalizing and internalizing behavior from kindergarten through Grade 8 for children who were and were not physically abused during the first 5 years of life. Early lifetime history of physical abuse (11.8% of sample) was determined through interviews with mothers during the prekindergarten period; mothers and children provided data on vulnerability and protective factors. Regardless of whether the child was abused, being African American; being male; having low early social competence, low early socioeconomic status (SES), and low adolescent SES; and experiencing adolescent harsh discipline, low monitoring, and low parental knowledge were related to higher levels of externalizing problems over time. Having low early social competence, low early SES, low adolescent SES, and low proactive parenting were related to higher levels of internalizing problems over time. Furthermore, resilience effects, defined as significant interaction effects, were found for unilateral parental decision making (lower levels are protective of externalizing outcomes for abused children), early stress (lower levels are protective of internalizing outcomes for abused children), adolescent stress (lower levels are protective of internalizing outcomes for abused children), and hostile attributions (higher levels are protective of internalizing outcomes for abused children). The findings provide a great deal of support for an additive or main effect perspective on vulnerability and protective factors and some support for an interactive perspective. It appears that some protective and vulnerability factors do not have stronger effects for physically abused children, but instead are equally beneficial or harmful to children regardless of their abuse status.

The objectives of this study is to identify factors associated with lack of preventive dental care among U.S. children and state-level factors that explain variation in preventive dental care access across states. We performed bivariate analyses and multilevel regression analyses among 68,350 children aged 5-17 years using the 2007 National Survey of Children's Health data and relevant state-level data. Odds ratios (ORs) for child- and state-level variables were calculated to estimate associations with preventive dental care. We calculated interval odds ratios (IOR), median odds ratios (MOR), and intraclass correlation coefficients (ICC) to quantify variation in preventive dental care across states. Lack of preventive dental care was associated with various child-level factors. For state-level factors, a higher odds of lack of preventive dental care was associated with a higher percentage of Medicaid-enrolled children not receiving dental services (OR = 1.30, 95 % confidence interval (CI): 1.15-1.47); higher percentage of children uninsured (OR = 1.48, 95 % CI: 1.29-1.69); lower dentist-to-population ratio (OR = 1.36, 95 % CI: 1.03-1.80); and lower percentage of dentists submitting Medicaid/State Children's Health Insurance Program claims (OR = 1.04, 95 % CI: 1.01-1.06). IORs for the first three state-level factors did not contain one, indicating that these state-level characteristics were important in understanding variation across states. Lack of preventive dental care varied by state (MOR = 1.40). The state-level variation (ICC = 3.66 %) accounted for a small percentage of child- and state-level variation combined. Child- and state-level characteristics were associated with preventive dental care access among U.S. children aged 5-17 years. State-level factors contribute to variation in dental care access across states and need to be considered in state-level planning.

There are currently inadequate data regarding the prevalence of dental caries and its associated variables, among Palestinian children. To determine the current prevalence of dental caries and related variables, among Palestinian children in East Jerusalem. A stratified sample of 286 East Jerusalem Palestinian children was selected, employing randomly chosen sixth grade clusters from three pre-selected socio-economic school groups. Dental caries was recorded according to WHO recommendations. Salivary flow, pH, buffer capacity and microbial parameters, were recorded according to previously employed methodologies. The mean level of caries experience, by DMFT, was 1.98 ± 2.05. This level was higher than those found among Israeli children, but lower than several other Middle Eastern countries. In uni-variate analysis, significant associations were revealed between caries and school categories, which indicated lower, middle and higher socio-economic position(SEP), mothers' employment, home densities, dental visits, tooth brushing, Streptococci mutans (SM), Lactobacilli (LB), and saliva pH. According to a linear logistic regression model, children learning in lower SEP schools, with higher SM levels and more acidic saliva, had a higher chance of experiencing dental caries. These findings should be considered in the planning of services and dental health care programs for Palestinian children.

Structural and functional perspectives on classification and seriation in psychotic and normal children.

This study describes a strategy for examining cognitive functioning in psychotic and normal children without the usual confounding effects of marked differences in cognitive structure that occur when children of the same age are compared. Participants were 14 psychotic children, 12 males and 2 females, mean age 9-2, matched with normal children at preoperational and concrete operational stage levels on a set of Piagetian classification tasks. The mean age of the normal children was 6-4, replicating the usually found developmental delay in psychotic samples. Participants were then compared on both structural level and functional abilities on a set of tasks involving seriation of sticks; the higher-level children were also administered a seriation drawing task. Analysis of children's processes of seriating and seriation drawings indicated that over and above the structural retardation, psychotic children at all levels showed functional deficits, especially in the use of anticipatory imagery. The implications for general developmental theory are that progress in structural development is not sufficient for imaginal development, and that structural development of logical concepts is relatively independent of the development of imagery. It was suggested that "thought disorder" may not be a disordered structure of thinking or a retardation in psychotic populations but rather a mismatch between higher-level logical structures and lower-level functions.

Defense mechanisms and psychological adjustment in childhood.

Sandstrom, Marlene J; Cramer, Phebe

2003-08-01

The association between maturity of defense use and psychological functioning was assessed in a group of 95 elementary school children. Defense mechanisms were measured using a valid and reliable storytelling task, and psychological adjustment was assessed through a combination of parent and self-report questionnaires. Correlational analyses indicated that children who relied on the developmentally immature defense of denial reported higher levels of self-rated social anxiety and depression and received higher ratings of parent-reported internalizing and externalizing behavior problems. However, children who made use of the developmentally mature defense of identification exhibited higher scores on perceived competence in social, academic, conduct, athletic, and global domains. Significantly, there was no relationship between children's use of denial and their level of perceived competence or between children's use of identification and their degree of maladjustment.

Background Experience in institutional/orphanage care has been linked to increased mental health problems. Research suggests children adopted from institutions experience specific difficulties related to inattention/overactivity. Evidence of internalizing and conduct problems relative to non-adopted peers has been found in early childhood and early adolescence, but problems may not differ from other adopted children. This study clarifies the understanding of behavioral and emotional symptoms of post-institutionalized (PI) children during middle childhood. Methods Eight to eleven-year-old PI children (n=68) and two comparison groups, children internationally adopted from foster care (n=74) and non-adopted children (n=76), and their parents completed the MacArthur Health and Behavior Questionnaire related to ADHD, externalizing, and internalizing symptoms. Group means for symptom level and number of children with symptoms above clinical cutoffs were compared. Results PI children displayed an increased level of ADHD symptoms per parent report. PI child and parent report indicated a higher number of PI children above clinical ADHD cutoff. Both groups of internationally adopted (IA) children had higher levels of externalizing symptoms relative to non-adopted children, with parent report indicating higher numbers of IA children above the externalizing clinical threshold. Informants differed in their report of internalizing symptoms. Parents indicated both IA groups displayed increased internalizing symptom levels and greater numbers above clinical threshold; however, children reported this to be true only for the PI group. Conclusions PI children differ from non-adopted peers across symptom domains in middle childhood. Whether these concerns were more broadly associated with international adoption rather than institutional care depended on symptom domain and informant. An understanding of this variability may be beneficial for treatment and intervention. PMID:20649913

To evaluate the influence of volume overload of the left (LV) and right ventricle (RV) and pressure overload of LV and restrictive physiology on levels of N-terminal proatriopeptide (ANPN) and N-terminal pro-brain natriuretic peptide (NT-proBNP). We studied 41 children with atrial septal defect (ASD), 35 with patent ductus arteriosus (PDA), 27 with coarctation of the aorta (CoA), 25 with restrictive physiology caused by Mulibrey nanism, and 64 control children. We measured serum concentrations of natriuretic peptides and evaluated ventricular size and function with echocardiography. In patients with ASD, PDA, and Mulibrey nanism, levels of both ANPN and NT-proBNP were higher than in controls but in children with CoA, only ANPN levels were higher. ANPN levels correlated with RV size in ASD and NT-proBNP levels with LV size in PDA. In patients with restriction, NT-proBNP levels correlated negatively with LV size. Correlation between echo measurements and levels of natriuretic peptides varied according to loading condition. Measurement of natriuretic peptide levels provides a supplemental method for non-invasive haemodynamic evaluation of children's heart disease.

Participation in home, extracurricular, and community activities is a desired outcome of rehabilitation services for children and young people with cerebral palsy (CP). The purpose of this study was to investigate the effect of age and gross motor function on participation among children and young people with CP. Five hundred participants (277 males, 223 females) were grouped by age and Gross Motor Function Classification System (GMFCS) level. There were 291 children aged 6 to 12 years and 209 young people aged 13 to 21 years. There were 128 participants in GMFCS level I, 220 in levels II/III, and 152 in levels IV/V. Participants completed the Children's Assessment of Participation and Enjoyment to measure number of activities (diversity) and how often they were performed (intensity) in the past 4 months. Children had higher overall participation diversity and intensity than young people (p<0.001). Children and young people in GMFCS level I had the highest overall participation, followed by children and young people in levels II/III and IV/V. Children had higher participation in recreational (p<0.001) but not formal (such as team sports or clubs) or physical activities. Children (p<0.01) and young people (p<0.001) in level I had the highest participation in physical activities; diversity and intensity were generally low. The findings provide evidence of the effect of age and gross motor function on participation of children and young people with CP. Low participation in physical activities may have implications for fitness and health, especially for children and young people in GMFCS levels IV and V.

This study examines the relationship between parenting and proactive versus reactive aggression among preschool children in China. Children (1164) from 10 kindergartens in Shanghai were rated by their parents and teachers using the Parent Behavior Inventory (PBI) and the Aggressive Behavior-Teacher's Checklist. Children had higher levels of reactive than proactive aggression, and older children and boys had higher levels of both proactive and reactive aggression. Hostile/coercive parenting style and low father education were significantly linked to aggression in children. These findings suggest that parenting style and type of aggression should be addressed when considering prevention and intervention. Crown Copyright © 2014. Published by Elsevier Inc.

The 2nd to 4th digit ratio (2D:4D) is thought to reflect exposure to androgens during foetal development. This study examined the relationship between low (more masculine) and high (more feminine) 2D:4D and body size at different stages of the life course, adult testosterone levels and number of children among males. Five hundred and fifty-eight men from rural Poland at the Mogielica Human Ecology Study Site participated in this study. Life history data and anthropometric measurements were collected. Salivary morning and evening testosterone levels among 110 men from the same population were measured. Low 2D:4D was related to higher birth weight (p = 0.04), higher birth length (p = 0.01), higher body mass during childhood and adolescence (p = 0.01), higher BMI (borderline significance, p = 0.06), higher number of children among fathers (p = 0.04) and higher testosterone levels during adulthood (p = 0.04). This study shows, for the first time in a single population, that digit ratio is related to sub-adult body size at different stages of the life course, adult testosterone levels and number of children. The observed results suggest that digit ratio might be a valuable predictor of male body size and reproductive characteristics.

Neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) shows diverse metabolic abnormalities such as urea cycle dysfunction together with citrullinemia, galactosemia, and suppressed gluconeogenesis. Such abnormalities apparently resolve during the first year of life. However, metabolic profiles of the silent period remain unknown. We analyzed oxidative stress markers and profiles of amino acids, carbohydrates, and lipids in 20 asymptomatic children with aspartate/glutamate carrier isoform 2-citrin-deficiency aged 1-10 years, for whom tests showed normal liver function. Despite normal plasma ammonia levels, the affected children showed higher blood levels of ornithine (p<0.001) and citrulline (p<0.01)--amino acids involved in the urea cycle--than healthy children. Blood levels of nitrite/nitrate, metabolites of nitric oxide (NO), and asymmetric dimethylarginine inhibiting NO production from arginine were not different between these two groups. Blood glucose, galactose, pyruvate, and lactate levels after 4-5h fasting were not different between these groups, but the affected group showed a significantly higher lactate to pyruvate ratio. Low-density and high-density lipoprotein cholesterol levels in the affected group were 1.5 times higher than those in the controls. Plasma oxidized low-density lipoprotein apparently increased in the affected children; their levels of urinary oxidative stress markers such as 8-hydroxy-2'-deoxyguanosine and acrolein-lysine were significantly higher than those in the controls. Results of this study showed, even during the silent period, sustained hypercitrullinemia, hypercholesterolemia, and augmented oxidative stress in children with citrin deficiency.

Children with congenital portosystemic venous shunt (PSVS) are at risk for developing pulmonary hypertension, irrespective of the severity of portal hypertension or liver damage. Altered metabolisms of nitric oxide (NO) and endothelin-1 (ET-1), which are linked with oxidative stress and control vascular tone, might contribute to the vascular disturbance. This study examined 14 children (aged 1-5 years) with congenital PSVS lacking major liver damage and portal hypertension. Serum levels of nitrite/nitrate (NOx) as stable metabolites of NO, and of asymmetric dimethylarginine (ADMA) as an endogenous NO synthase inhibitor were determined, along with the plasma level of ET-1. Oxidative stress, which might affect the production of such mediators, was also examined using specific urinary and blood markers. The NOx levels were significantly lower in affected children than in the age-matched control group, although ET-1 levels were significantly higher than the control levels. In the affected children, the ADMA levels and ADMA/NOx ratios were higher, respectively, by 30% and 130% and showed significant positive correlations with the shunt ratios. Oxidative stress markers, including plasma thiobarbiturate reactive substances and urinary acrolein-lysine and 8-hydroxy-2'-deoxyguanosine, were significantly higher in affected children than in the control group, consistent with them being subjected to enhanced oxidative stress. These results suggest the presence of altered metabolisms of vascular mediators and enhanced oxidative stress in asymptomatic preschool children with congenital PSVS.

To compare demographic and clinical characteristics among children from ethnic minorities and non-Hispanic white children with new-onset autoimmune Type 1 diabetes. We analysed a single-centre series of 712 children with new-onset autoimmune Type 1 diabetes between January 2008 and March 2011. The median (range) age was 9.7 (0.3-18.1) years, the mean (sd) BMI percentile was 69.7 (25.4) and 48.3% of the cohort were girls. The cohort comprised 57.3% non-Hispanic white, 20.5% Hispanic and 14.8% African-American children, and 7.4% were of other, mixed or unknown race. The Hispanic subgroup, compared with non-Hispanic white subgroup, had a higher mean (sd) C-peptide level [0.82 (1.62) vs 0.55 (0.47) ng/ml; P=0.004), and a greater proportion of children with elevated BMI (overweight or obesity; 49.6% vs 32.5%; P<0.001) and diabetic ketoacidosis (51.8% vs 38.2%; P=0.006). The African-American group had a higher mean (sd) glucose level [24.4 (12.8) vs 21.4 (10.7) mmol/l; P=0.017], a greater proportion of children with ketoacidosis (56.7% vs 38.2%; P=0.001), a greater proportion with elevated BMI (52.9% vs 32.5%; P<0.001), and a lower proportion of children at pre-pubertal stage (49.0% vs 61.6%; P=0.01), and tended to have higher C-peptide levels [0.65 (0.59) vs 0.55 [0.47] ng/ml; P=0.079) compared with the non-Hispanic white children. The differences in C-peptide levels compared with non-Hispanic white children persisted for Hispanic (P=0.01) but not African-American children (P=0.29) after adjustment for age, sex, BMI, ketoacidosis, glucose, Tanner stage and autoantibody number. At the onset of paediatric autoimmune Type 1 diabetes, Hispanic, but not African-American children had higher C-peptide levels, after adjustment for potential confounders, compared with non-Hispanic white children. These findings suggest that ethnicity may contribute to the heterogeneity of Type 1 diabetes pathogenesis, with possible implications for intervention. © 2017 Diabetes UK.

Down syndrome, caused by trisomy 21, is characterized by congenital abnormalities as well as mental retardation. From the neonatal stage through adolescence, patients with Down syndrome often have several complications. Thus, it is important to attain knowledge of the prevalence of these comorbidities in children with Down syndrome. We, therefore, evaluated the biochemical data, thyroid function, and anthropometric parameters, and analyzed the association among them in Japanese children and early adolescents with Down syndrome. There was no difference in the prevalence of obesity and overweight between boys and girls. The level of uric acid was higher in boys than in girls. Moreover, the prevalence of hyperuricemia was also higher in boys than in girls (approximately 32% and 10%, respectively). The prevalence of subclinical hypothyroidism in children with Down syndrome was approximately 20%, with no significant sex differences. The levels of uric acid and dehydroepiandrosterone-sulfate were positively associated with age, while the levels of thyroid-stimulating hormone and free thyroxine had a negative association with age. Overall, children with Down syndrome, exhibit a higher incidence of hyperuricemia. Therefore, uric acid levels, as well as thyroid function, from childhood to early adulthood should be monitored in this patient cohort.

Neighborhood context and the Hispanic health paradox: differential effects of immigrant density on children׳s wheezing by poverty, nativity and medical history.

Prior research suggests that immigrant enclaves provide respiratory health benefits for US Hispanic residents. We test if immigrant enclaves provide differential respiratory health benefits for Hispanic children in El Paso (Texas) based on individual-level factors. Results reveal that higher neighborhood immigrant density is associated with reduced odds of wheezing, but that the protective immigrant enclave effect is modified by poverty, general health status, body mass index (BMI), and caretaker nativity. Higher immigrant density is significantly more protective for poor children and those with foreign-born caretakers; conversely, it is significantly less protective for children in worse health and those with higher BMI. These findings foster a novel understanding of how immigrant enclaves may be differentially protective for Hispanic children based on individual-level factors. Copyright © 2014 Elsevier Ltd.

2014-01-01

Time-sampled observations of Head Start preschoolers' (N = 264; 51.5% boys; 76% Mexican American; M = 53.11 and SD = 6.15 months of age) peer play in the classroom were gathered during fall and spring semesters. One year later, kindergarten teachers rated these children's school competence. Latent growth models indicated that, on average, children's peer play was moderately frequent and increased over time during preschool. Children with higher initial levels or with higher slopes of peer play in Head Start had higher levels of kindergarten school competence. Results suggest that Head Start children's engagement with peers may foster development of skills that help their transition into formal schooling. These findings highlight the importance of peer play, and suggest that peer play in Head Start classrooms contributes to children's adaptation to the demands of formal schooling. PMID:24882941

Coparenting and children's disruptive behavior: Interacting processes for parenting sense of competence.

Latham, Rachel M; Mark, Katharine M; Oliver, Bonamy R

2018-02-01

Parenting sense of competence (PSOC) is a critical aspect of parental adjustment that may be undermined by children's disruptive behavior. Interparental relationships have been shown to shape how parents react and respond to their children's characteristics, but little is known about the role of parenting teamwork, known as 'coparenting.' We examined mothers' and fathers' perceptions of children's disruptive behavior and the quality of coparenting, as well as their interaction in association with PSOC. Mothers and fathers from 108 'intact' families participating in the Twins, Family, and Behavior (TFaB) Study reported on their children's disruptive behavior, coparenting and PSOC via postal questionnaire (Mchild age = 6 years, SDchild age = 6.12 months). Dyadic multilevel analyses revealed that higher levels of children's disruptive behavior related to lower levels of parents' PSOC and perceptions of higher-quality coparenting were associated with higher PSOC. Notably, and as hypothesized, there was a significant interaction between coparenting and children's disruptive behavior such that perceptions of high quality coparenting buffered PSOC from its negative association with children's disruptive behavior. High-quality coparenting is an important aspect of family functioning that may protect the PSOC of parents dealing with high levels of children's disruptive behavior.

This study aimed to determine the optimal cut-off for autism spectrum disorder (ASD) screening in 66-month-old children, and to explore the distribution of ASD screening and diagnosis in Taiwan. The Taiwan Birth Cohort Study dataset was used (N = 20,095). The Modified Checklist for Autism in Toddlers (M-CHAT) cut-off point of 13/14 was considered optimal for screening of children at 66 months. More children were diagnosed with ASD in urban areas. Parents of children diagnosed with ASD had a higher level of education, but parents of children with a lower level of education were screened as being at higher risk of ASD. Urban disparity and parental level of education effected parental awareness of the illness and the rate of ASD diagnosis.

Autism is a neurodevelopmental disorder identified with higher frequency of serotonin abnormalities and gastrointestinal (GI) and sleep problems. This study aimed to evaluate the plasma levels of serotonin, GI symptoms, and sleep problems, and their relationship with autism severity in children with autism. Thirty-five children with autism and 31 healthy subjects were studied. GI problems, sleep disorders, and severity of disorder were assessed. Plasma serotonin was determined using ELISA. There was no significant association between GI problems and autism severity, but a significant positive correlation was seen between different indicators of sleep disorder and severity of autism. Plasma levels of serotonin were significantly higher in autistic children and a significant negative correlation was observed between plasma levels of serotonin and autism severity (r = -0.39, P = 0.02). Elevated plasma serotonin in autistic children and its negative correlation with disease severity may indicate involvement of the neurotransmitter in the neurophysiologic mechanism of autism.

We studied whether children with severe developmental disabilities (SDDs) who have a comorbid behavioral disorder also have higher rates of special healthcare needs (SHCNs). We used a matched-comparison control group design to establish whether SHCNs were higher in children with SDDs with behavioral disorders versus children with SDDs without behavioral disorders. Thirty-six children were matched for age (mean 12 y 6 mo; range 5 y 2 mo-18 y 8 mo), sex (24 males, 12 females), ethnicity (22 non-white), mental retardation level (22 moderate, eight severe, six profound), and Diagnostic and Statistical Manual of Mental Disorders, 4th edition axis I diagnosis (18 autism spectrum disorder, 10 specified syndrome, eight mental retardation not otherwise specified). Measures included the Achenbach Child Behavior Checklist, behavioral observation, health status examination, and Childhood Health Questionnaire (CHQ). Children with SDDs with behavioral disorders had significantly higher levels of SHCN, as measured by the CHQ and health status examination. Children with SDDs with behavioral disorders had a twofold higher incidence of SHCNs than children with SDDs without behavioral disorders. No difference was observed in the number or types of prescription medication that children received. The findings suggest that SHCNs contribute to the occurrence and/or intensity of behavioral disorders in children with SDD and may require interdisciplinary care coordination.

Stress may affect health negatively. Therefore, it is important to identify risks factors for high levels of stress. Previous studies indicate that parents report higher levels of stress than adults without children. Whether this it due to having children or due to other circumstances is unknown. The purpose of this study is to investigate whether parents have higher levels of stress than adults without children after controlling for possible confounders. A possible interaction between being a parent and working time on perceived stress will be examined. Cross-sectional data from Danish Health and Morbidity Survey 2000 were used. 3,083 men and 2,813 women aged 25-49 years answered one question on perceived stress. All analyses were stratified on sex and marital status and adjusted for age, socio-economic level, income and work hours/week. No differences in perceived stress between men and women with and without children were found. Women, who were lone parents and worked more than 37 hours a week, had a markedly increased level of stress (OR: 3.2, 95%CI: (1.3-7.8)) compared to single women without children working 37 hours a week. Children in the household did not appear to be the cause of a high level of perceived stress. Single mothers with long working hours were an exception to this conclusion.

Previous studies found that the increasing number of paediatricians in the United States was associated with improved childhood immunization coverage, while the increasing poverty level and the lack of health insurance reduced access to health care. We evaluated whether changes in the number of paediatricians, poverty level and health insurance affected national childhood immunization coverage in the state levels of the United States. Data were collected primarily from the US National Immunization Surveys, series 4:3:1:3:3 from years 1995 and 2003. Ordinal logistic regression analysis was used to analyse the relationships among variables. Over 8 years studied, immunization coverage increased for children aged 19-35 months from 52.3% to 79.8% in the 50 states. The average number of paediatricians per 1000 births increased 28.7% while the percentage of children without health insurance declined 15.6%, and the percentage of children who lived in poverty level declined 17.3%. In 1995, the states with higher immunization coverage were associated with higher numbers of paediatricians [odds ratio (OR), 32.73; 95% confidence interval (CI), 5.96-179.77]. In 2003, the higher numbers of paediatricians still played a role in the increased immunization coverage (OR, 4.69; 95% CI, 1.01-21.78); however, the higher rate of uninsured children in 2003 had an even greater effect upon immunization coverage. Compared with states with lower rates of uninsured children, states with intermediate and higher rates of uninsured children had sixfold (OR, 0.16; 95% CI, 0.03-0.81) and 16-fold (OR, 0.06; 95% CI, 0.01-0.40) decreased childhood immunization coverage, respectively. Between 1995 and 2003 in the United States, the lack of health insurance became more prominent than the supply of paediatricians in affecting immunization coverage for children aged 19-35 months. Future improvements in insurance coverage for children will likely lead to greater immunization coverage.

Effects of gender and level of parental involvement among parents in drug treatment.

2003-05-01

Most studies of parents in drug treatment have focused exclusively on mothers, and few studies have examined the effects of parents' level of involvement with their children on the parents' drug use and psychological functioning, either before or after treatment. This study examined mothers and fathers (n = 331) who were parents of children under the age of 18; participants were sampled from 19 drug treatment programs across four types of treatment modalities in Los Angeles County. A majority of each group (57% of 214 mothers and 51% of 117 fathers) were classified as being highly involved with their children. At the baseline assessment, higher parental involvement was related to lower levels of addiction severity, psychological severity, and symptoms of psychological distress, and to higher levels of self-esteem and perception of parenting skills. In general, fathers had higher levels of alcohol and drug-use severity than did mothers, but fathers who were more involved with their children showed lower levels of addiction severity than fathers who were less involved. Parental involvement at baseline was unrelated to drug use at the 12-month follow-up, although parents who were less involved with their children reported experiencing more stressors. Given the association of parental involvement with lower levels of addiction severity and psychological distress at baseline, treatment protocols should build upon the positive relationships of parents with their children, and seek to improve those of less-involved parents.

Parents of children with autism spectrum disorders (ASD) may experience higher levels of stress and health problems than parents of children with typical development. However, most research has focused on mothers, with emphasis on parent-reported stress and wellbeing. This study compared parenting responsibility, distress, anxiety, depression, cortisol, alpha-amylase, and cardiovascular activity between 19 mother-father dyads of children with ASD. Mothers reported higher parenting responsibility, distress, anxiety, and depression than fathers, while fathers had higher blood pressure and heart rate variability. Mothers and fathers had lower than average morning cortisol levels, suggesting stress effects on the hypothalamic-pituitary-adrenal-axis. Parents of children with ASD may benefit from routine health screening (particularly adrenal and cardiovascular function) and referral for stress reduction interventions or supports.

Heating indoor living environments elevates air pollution in Ulaanbaatar, Mongolia. This study was conducted to investigate the influence of season and living environment on children's urinary 1-hydroxypyrene (1-OHP) levels in Ulaanbaatar, Mongolia. Our study subjects were 320 children aged 11-15 years living in gers, brick houses and apartments, in ger and non-ger areas of Ulaanbaatar. Spot urine samples and questionnaires were collected three times from each subject in three seasons, September (warm) and December (cold) in 2011 and March (moderate) in 2012. Urinary 1-OHP was analyzed by high-performance liquid chromatography with fluorescent detection (HPLC/FLD). Generalized estimating equation (GEE) models were applied to estimate the seasonal and residential effects on 1-OHP levels, adjusting for demographic and environmental factors. Children's urinary 1-OHP levels showed significant seasonal differences with 0.30 ± 0.57 μmol/mol creatinine in cold season, 0.14 ± 0.12 μmol/mol creatinine in moderate season, and 0.14 ± 0.21 μmol/mol creatinine in warm season. After controlling confounding factors, the GEE model showed that season, living area, and housing type had significant influence on children's urinary 1-OHP levels. Urinary 1-OHP levels in the cold and moderate seasons were, respectively 2.13 and 1.37 times higher than the warm season. Urinary 1-OHP levels for children living in ger areas were 1.27 times higher than those living in non-ger areas. Children who lived in gers or brick houses had 1.58 and 1.34 times higher 1-OHP levels, respectively, compared with those living in apartments. Children's urinary 1-OHP levels were associated with either estimated NO2 or SO2 concentrations at their home addresses in Ulaanbaatar. Mongolian children's urinary 1-OHP levels were significantly elevated during the cold season, and for those living in ger areas, gers, or brick houses in Ulaanbaatar. Children's urinary 1-OHP levels were associated PAH co-pollutants SO2 and NO2, suggesting elevated 1-OHP levels may be attributable to PAH emissions from coal burning and traffic respectively, with indoor emissions from stoves further contributing to elevated 1-OHP in some children.

This study examined family, school, and community factors and the relationships to racial-ethnic attitudes and academic achievement among 98 African American fourth-grade children. It has been posited that young people who feel better about their racial-ethnic background have better behavioral and academic outcomes, yet there is a need for more empirical tests of this premise. Psychometric information is reported on measures of parent, teacher, and child racial-ethnic attitudes. Path analysis was used to investigate ecological variables potentially related to children's racial-ethnic attitudes and achievement. Parental education and level of racial-ethnic pride were correlated and both were related to children's achievement though in the final path model, only the path from parental education level was statistically significant. Children whose teachers exhibited higher levels of racial-ethnic trust and perceived fewer barriers due to race and ethnicity evidenced more trust and optimism as well. Children living in communities with higher proportions of college-educated residents also exhibited more positive racial-ethnic attitudes. For children, higher racial-ethnic pride was related to higher achievement measured by grades and standardized test scores, while racial distrust and perception of barriers due to race were related to reduced performance. This study suggests that family, school, and community are all important factors related to children's racial-ethnic attitudes and also to their academic achievement.

Tibetans have lived at high altitude longer than any other high-altitude population. Still little is known about their lung function and especially among children. This study compared lung function values of forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and forced expiratory flow at 50% of FVC (FEF50) in children living at various altitudes in Tibet and with different ancestries. A cross-sectional study of lung function was performed among 9-10-year-old native Tibetan and Han Chinese children living at 3700 meters above sea level, and among native Tibetan children living at 4300 meters above sea level. The adjusted FVC and FEV1 were significantly higher in Tibetan children living at 4300 m above sea level as compared to Tibetans living at 3700 m. Tibetans living at 3700 m had higher FVC and FEV1 than Han Chinese living at the same altitude. All Tibetan children had on average higher FEF50 than Han Chinese. Tibetan children living at an altitude of 4300 m had relatively higher lung function than those living at 3700 m, and there were differences in lung function between Tibetans and Han Chinese who live at the same altitude. It seems likely that genetic factors involved in long-term adaptation to high altitude and cultural attributes could have contributed to the study findings.

Toxic levels of heavy metals and low levels of essential minerals have been suggested to play a critical role in the pathogenesis of autism spectrum disorders (ASD). This study documents the levels of heavy metals and essential minerals in hair samples of children with ASD in Muscat, the urbanized capital of Oman, Muscat. The study included 27 children with ASD and 27 matched non-ASD controls. Parental interviews were held and dietary intake questionnaires completed in conjunction with the collection of hair samples. Analysis of heavy metals and essential minerals was carried out by inductively coupled plasma mass spectrometry. Chi-square analysis and non-parametric Fisher's exact tests were used to assess statistical significance. Children with ASD had significantly higher levels of all 11 analyzed heavy metals in their hair samples (P < 0.05), ranging from 150 to 365 % of control levels. ASD children also had significantly higher levels of essential minerals sulfur, sodium, magnesium, potassium, zinc, and iron, but lower levels of calcium and copper in their hair samples. This study corroborates data from previous studies in different parts of the world indicating the presence of elevated levels of heavy metals and selective depletion of essential minerals in the hair of children with ASD.

Chronic exposure to heavy metals could affect cell-mediated immunity. The aim of this study was to explore the status of memory T cell development in preschool children from an e-waste recycling area. Blood lead (Pb) levels, peripheral T cell subpopulations, and serum levels of cytokines (IL-2/IL-7/IL-15), relevant to generation and homeostasis of memory T cells were evaluated in preschool children from Guiyu (e-waste-exposed group) and Haojiang (reference group). The correlations between blood Pb levels and percentages of memory T cell subpopulations were also evaluated. Guiyu children had higher blood Pb levels and increased percentages of CD4 + central memory T cells and CD8 + central memory T cells than in the Haojiang group. Moreover, blood Pb levels were positively associated with the percentages of CD4 + central memory T cells. In contrast, Pb exposure contributed marginally in the change of percentages of CD8 + central memory T cells in children. There was no significant difference in the serum cytokine levels between the e-waste-exposed and reference children. Taken together, preschool children from an e-waste recycling area suffer from relatively higher levels of Pb exposure, which might facilitate the development of CD4 + central memory T cells in these children.

Investigated the effects of self-regulation as a moderator of the relations between coping efforts and psychological symptoms of children of divorce. The interactions of two dimensions of self-regulation (task orientation and approach-flexibility) and two dimensions of coping (active and avoidant) predicting children's postdivorce symptoms were tested using a sample of 199 divorced mothers and their children, ages 8 to 12. The approach-flexibility dimension moderated the relations of both active and avoidant coping with children's self-report of anxiety. At higher levels of approach-flexibility, active coping was negatively related to anxiety, while at lower levels of approach-flexibility, active coping was unrelated to anxiety. Avoidant coping was unrelated to anxiety at higher levels of approach-flexibility, whereas at lower levels of approach-flexibility, avoidant coping was positively related to anxiety. The task orientation dimension did not interact with coping, but had direct, independent effects on children's self-report of conduct problems, depression, and parent-report of internalizing and externalizing behavior problems. The implications for understanding children's coping with divorce and future directions for research are discussed.

Lead (Pb) is a developmental neurotoxicant and can cause abnormal development of the nervous system in children. Hence, the aim of this study was to investigate the effect of Pb exposure on child olfactory memory by correlating the blood Pb levels of children in Guiyu with olfactory memory tests. We recruited 61 preschool children, 4- to 7-years of age, from Guiyu and 57 children from Haojiang. The mean blood Pb level of Guiyu children was 9.40 μg/dL, significantly higher than the 5.04 μg/dL mean blood Pb level of Haojiang children. In addition, approximately 23% of Guiyu children had blood Pb levels exceeding 10.00 μg/dL. The correlation analysis showed that blood Pb levels in children highly correlated with e-waste contact (r s  = 0.393). Moreover, the mean concentration of serum BDNF in Guiyu children (35.91 ng/ml) was higher than for Haojiang (28.10 ng/ml) and was positively correlated with blood Pb levels. Both item and source olfactory memory tests at 15 min, 5 h and 24 h after odor exposure showed that scores were lower in Guiyu children indicative of reduced olfactory memory in Guiyu children. Olfactory memory tests scores negatively correlated with blood Pb and serum BDNF levels, but were positively associated with parental education levels. At the same time, scores of both tests on children in the high blood Pb level group (blood Pb levels > 5.00 μg/dL) were lower than those in the low blood Pb level group (blood Pb levels ≤ 5.00 μg/dL), implying that Pb exposure decreases olfactory memory in children. Our findings suggest that Pb exposure in e-waste recycling and dismantling areas could result in an increase in serum BDNF level and a decrease in child olfactory memory, in addition, BDNF might be involved in olfactory memory impairment.

Perfluoroalkyl substances (PFASs) are accumulating in our environment and human exposure to these potentially harmful chemicals are of growing concern. In the present study, 116 children aged 6-11 and 143 mothers in two locations in Denmark donated blood samples as a supplement to their participation in the large European human biomonitoring project, DEMOCOPHES (Demonstration of a study to COordinate and Perform Human Biomonitoring on a European Scale). The blood samples were analyzed by LC-MS/MS for the concentration of six PFASs: PFOA, PFHxS, PFNA, PFDA, br-PFOS and n-PFOS. All measured compounds were above the detection limit in both mothers and children except for PFHxS in one child. There was a significant correlation between the levels in children and their mothers, indicating a family-related exposure pattern. However, we also found that the levels of PFOA, PFNA, PFDA, br-PFOS and total-PFOS were significantly higher in children compared to their mothers. This may be due to higher exposure in children through for example dust and soil, and due to the fact that children are smaller in body size and blood volume and hence have a lower storage capacity. Furthermore, we found an association between plasma levels and the age of the mothers and higher levels of plasma PFASs in mothers with low parity. There were no associations between PFAS concentrations and residential area, dietary habits of the participants or with respect to the birth order of the children. The levels are comparable to concentrations found in other Western countries. Copyright © 2014 Elsevier Ltd. All rights reserved.

The human mannose-binding lectin (MBL) and ficolins (FCN) are involved in pathogen recognition in the first line of defence. They support activation of the complement lectin cascade in the presence of MBL-associated serine protease 2 (MASP-2), a protein that cleaves the C4 and C2 complement components. Recent studies found that distinct MBL2 and FCN2 promoter variants and their corresponding serum levels are associated with relative protection from urogenital schistosomiasis. We investigated the contribution of MASP-2 levels and MASP2 polymorphisms in a Nigerian study group, of 163 individuals infected with Schistosoma haematobium and 183 healthy subjects. MASP-2 serum levels varied between younger children (≤12 years) and older children (>12 years) and adults (P = 0.0001). Younger children with a patent infection had significantly lower MASP-2 serum levels than uninfected children (P = 0.0074). Older children and adults (>12 years) with a current infection had higher serum MASP-2 levels than controls (P = 0.032). MBL serum levels correlated positively with MASP-2 serum levels (P = 0.01). MASP2 secretor haplotypes were associated with MASP-2 serum levels in healthy subjects. The heterozygous MASP2 p.P126L variant was associated with reduced serum MASP-2 levels (P = 0.01). The findings indicate that higher MASP-2 serum levels are associated with relative protection from urogenital schistosomiasis in Nigerian children. © 2015 John Wiley & Sons Ltd.

Measurement of human pancreatic polypeptide may be useful for assessment of gastrointestinal function, integrity of the parasympathetic nervous system or screening for endocrine neoplasia. In adults hPP levels have been reported to increase with age. However hPP levels throughout childhood have not been well characterized in comparison with the adult range. We studied fasting human pancreatic polypeptide (hPP) from 45 pediatric patients, from infancy - 15 years, and 18 older adolescents and adults aged 16-45 years. The mean hPP level of children (233 +/- 147 pg/ml) was significantly higher than that (113 +/- 35 pg/ml) of adults (P less than .0001). There was no difference in mean hPP levels of children with normal growth hormone secretion compared to growth hormone deficient patients. There was no effect of gender or body mass index on hPP levels. We conclude that fasting hPP levels must be interpreted with respect to the age of the subject, children particularly, in that preteens may have higher fasting levels than older teenagers and adults.

Parenting strategies involving psychological control are associated with increased adjustment problems in children. However, no research has examined the extent to which culture and psychological control predict children's stress physiology. We examine cultural differences in maternal psychological control and its associations with children's cortisol. Chinese (N = 59) and American (N = 45) mother-child dyads participated in the study. Mothers reported on psychological control. Children's cortisol was collected during a stressor and two indices of Area Under the Curve (AUC) were computed: AUCg which accounts for total output, and AUCi, which captures reactivity. Results indicate that Chinese mothers reported higher levels of psychological control and Chinese children had higher levels of AUCg than their American counterparts. Across both cultures, psychological control was significantly associated with increased cortisol levels as indexed by AUCg. There were no associations for AUCi. Finally, mediation analyses demonstrated that psychological control fully explained cultural differences in children's cortisol stress response as indexed by AUCg. © 2016 John Wiley & Sons Ltd.

To assess intelligence and its relationship with blood phenylalanine concentrations and socioeconomic status in patients with phenylketonuria after 6 to 12 years of treatment. Sixty-three children were classified according to phenylalanine levels and socioeconomic status and assessed using the Wechsler Intelligence Scale for Children. The Statistical Package for the Social Sciences (SPSS) was used to analyze phenylalanine; ANOVA was used to analyze intelligence quotients (IQ) and phenylalanine levels; and ordinal logistic regression was used to analyze the likelihood of higher IQ. The overall IQ scores of 90.5% of the children were within a range from borderline intellectual deficiency to very high intelligence; for verbal IQ this proportion was 96.8% and 92.1% had performance IQ scores within this band. The categories from low to upper-medium socioeconomic status contained 98.4% of patients' families. The likelihood of having medium to high IQ was 4.29 times greater for children with good phenylalanine control and 4.03 greater for those from higher socioeconomic strata. Treatment prevented mental retardation in 90.5% of the patients. Control of phenylalanine levels and higher socioeconomic status were associated with higher IQ scores.

The contribution of housing renovation to children’s blood lead levels: a cohort study

PubMed Central

2013-01-01

Background Routine renovation of older housing is a risk factor for childhood lead poisoning, but the contribution to children’s blood lead levels is poorly defined for children with lower exposure levels. Methods We examined a prospective cohort of 276 children followed from 6 to 24 months of age. We conducted surveys of renovation activities and residential lead hazards and obtained blood lead level (B-Pb) every six months. We analyzed B-Pb in a repeated measures design using a mixed effects linear model. Results Parent reported interior renovation ranged from 11 to 25% of housing units at the four, 6-month periods. In multivariable analysis, children whose housing underwent interior renovation had a 12% higher mean B-Pb by two years of age compared with children whose housing units were not renovated (p < 0.01). The time between renovation and the child blood lead sample was associated with higher B-Pb (p-value for trend <0.01); compared to children in non-renovated housing, children whose housing units underwent renovation in the prior month had a 17% higher mean B-Pb at two years of age, whereas children whose housing renovation occurred in the prior 2–6 months had an 8% higher mean B-Pb. We also found an association between higher paint lead loading, measured using an X-ray fluorescence (XRF) based paint lead index, and child B-Pb (p = 0.02); for every 10 mg/cm2 increase in paint lead loading index there was a 7.5% higher mean childhood B-Pb. Conclusions In an analysis of data collected before the recent changes to Environmental Protection Agency’s Lead, Renovation, Repair and Painting Rule, routine interior housing renovation was associated with a modest increase in children’s B-Pb. These results are important for the provision of clinical advice, for housing and public health professionals, and for policymakers. PMID:23981571

Children who met DSM-IV criteria for attention-deficit/hyperactivity disorder (ADHD) with functional impairment in at least one setting at 4–6 years of age were followed prospectively through age 18 years. On average, the 125 children (107 boys) with ADHD at baseline improved over time, but still continued to exhibit more symptoms, functional impairment, and risky behavior through adolescence than demographically matched healthy comparison children. These findings support the predictive validity of the diagnosis of ADHD at younger ages by demonstrating that the symptoms and impairment are enduring. Nonetheless, there were marked variations in developmental outcomes. Among children with ADHD, higher numbers of inattention and hyperactivity-impulsivity symptoms and higher number of concurrent symptoms (oppositional, conduct disorder, anxiety, and depression) measured at baseline each predicted higher future levels of the same dimension of symptoms. In addition, higher baseline levels of inattention, oppositional, conduct disorder, and anxiety symptoms predicted greater future functional impairment. Among children with ADHD, girls and children from families with lower family incomes had relatively poorer outcomes. Although outcomes varied along a continuum, approximately 10% of the children with ADHD at 4–6 years could be classified as functioning in the normative range on multiple measures during 15–18 years. Although this finding awaits replication, lower levels of hyperactivity-impulsivity symptoms at 4–6 years predicted more normative functioning during adolescence. These findings suggest that ADHD identified in early childhood predicts an increased likelihood of functional impairment through adolescence for most, but not all, children. PMID:26854503

Body composition and blood pressure in children based on age, race, and sex.

Brandon, L J; Fillingim, J

1993-01-01

We evaluated 675 nine- and twelve-year-old children for body composition and circulatory differences based on age, race, and sex. The specific variables measured included height, weight, triceps and subscapula skinfolds, body mass index, percentage fat, fat-free weight, and systolic, diastolic, and mean arterial blood pressures. A 2 x 2 x 2 factorial multiple analysis of variance (MANOVA) test of significance showed body composition and blood pressure differences (P < .01) for race, age, and sex. The univariate test of the specific variables within the factors showed that black children had higher fat-free weights and lower fat levels but higher blood pressure values (P < .05) than white children. Boys had lower fat levels than girls, and the older children had higher values on the body composition variables but not on blood pressure. Zero order correlations between body composition and blood pressure ranged from 0.14 to 0.55; systolic blood pressure and body weight shared the highest correlation. These data show that, although black children have less body fat than white children, they are heavier and have higher blood pressure. We hypothesize that some aspect of fat-free body weight may contribute to hypertension in black individuals.

Describe and compare the caregiver strain experienced among Indian mothers of children and young adults with cerebral palsy (CP) living in low resource settings. 62 consecutive children and young adults with spastic CP (mean age 6.0 ± 4.5, range 2-21) and their parents were recruited from an outpatient physiotherapy department for this cross-sectional study. Ability to walk was classified using the Gross Motor Function Classification System and mother's caregiver strain was measured using caregiver strain index (CSI). Mothers of children and young adults who have limited self-mobility perceived higher caregiver strain (mean CSI score 12.0 ± 1.3, p < 0.05) than mothers of children who can walk (mean CSI score 4.5 ± 3.0, p < 0.05). All 46 mothers of children and youth in GMFCS levels IV and V reported high levels of caregiver stress compared with only three of 16 mothers of children and youth who walk (levels I and II). Physiotherapists and occupational therapists serving children and youth with CP are encouraged to partner with families to identify goals for ease of caregiving, activity, and participation at home and in the community.

Availability of parks is associated with higher levels of physical activity among children and adolescents. Few studies examine actual park use and park-based physical activity in these populations. This study examined associations among individual, park, and neighborhood environmental characteristics and children's and adolescent's park-based physical activity. Data were collected in 2007 on 2712 children in 20 randomly selected parks in Durham NC. The System for Observing Play and Recreation in Communities (SOPARC) provided measures of physical activity. Hierarchic regression analysis assessed associations among individual, park, and neighborhood environmental characteristics and children's park-based physical activity. Data were analyzed in 2010. Of the 2712 children observed, 34.2% and 13.2% were engaged in walking or vigorous physical activity. Environmental features of parks were associated with activity levels whereas neighborhood characteristics were not. Physical activity was negatively associated with gender (girls) (p=0.003); presence of a parent (p<0.0001); presence of nonparental adult (p=0.006); and an interaction involving the 0-5 years age group and style of play (p=0.017). Higher level of physical activity was associated with presence of other active children (p<0.0001); courts (e.g., basketball); and an interaction between number of recreation facilities and formal activities (p=0.004). These social factors and design features should be considered in order to stimulate higher levels of park-based physical activity among children and adolescents.

Down syndrome, caused by trisomy 21, is characterized by congenital abnormalities as well as mental retardation. From the neonatal stage through adolescence, patients with Down syndrome often have several complications. Thus, it is important to attain knowledge of the prevalence of these comorbidities in children with Down syndrome. We, therefore, evaluated the biochemical data, thyroid function, and anthropometric parameters, and analyzed the association among them in Japanese children and early adolescents with Down syndrome. There was no difference in the prevalence of obesity and overweight between boys and girls. The level of uric acid was higher in boys than in girls. Moreover, the prevalence of hyperuricemia was also higher in boys than in girls (approximately 32% and 10%, respectively). The prevalence of subclinical hypothyroidism in children with Down syndrome was approximately 20%, with no significant sex differences. The levels of uric acid and dehydroepiandrosterone-sulfate were positively associated with age, while the levels of thyroid-stimulating hormone and free thyroxine had a negative association with age. Overall, children with Down syndrome, exhibit a higher incidence of hyperuricemia. Therefore, uric acid levels, as well as thyroid function, from childhood to early adulthood should be monitored in this patient cohort. PMID:28955133

1992-01-01

An anthropometric survey of children aged 0-59 months in north-west Uganda in February-March 1987 indicated a high prevalence of stunting but little wasting. Use of unprotected water supplies in the dry season, prolonged breast-feeding, and age negatively affected nutrition; in contrast, parental education level improved nutrition. Mortality during the 12 months following the survey was higher among those who had low weight-for-age and weight-for-height, but children who had low height-for-age did not have higher mortality. Weight-for-age was the most sensitive predictor of mortality at specificities > 88%, while at lower specificity levels weight-for-height was the most sensitive. Children whose fathers' work was associated with the distillation of alcohol had a higher risk of mortality than other children. The lowest mortality was among children whose fathers were businessmen or who grew tobacco.

As children learn they use their speech to express words and their hands to gesture. This study investigates the interplay between real-time gestures and speech as children construct cognitive understanding during a hands-on science task. 12 children (M = 6, F = 6) from Kindergarten (n = 5) and first grade (n = 7) participated in this study. Each verbal utterance and gesture during the task were coded, on a complexity scale derived from dynamic skill theory. To explore the interplay between speech and gestures, we applied a cross recurrence quantification analysis (CRQA) to the two coupled time series of the skill levels of verbalizations and gestures. The analysis focused on (1) the temporal relation between gestures and speech, (2) the relative strength and direction of the interaction between gestures and speech, (3) the relative strength and direction between gestures and speech for different levels of understanding, and (4) relations between CRQA measures and other child characteristics. The results show that older and younger children differ in the (temporal) asymmetry in the gestures-speech interaction. For younger children, the balance leans more toward gestures leading speech in time, while the balance leans more toward speech leading gestures for older children. Secondly, at the group level, speech attracts gestures in a more dynamically stable fashion than vice versa, and this asymmetry in gestures and speech extends to lower and higher understanding levels. Yet, for older children, the mutual coupling between gestures and speech is more dynamically stable regarding the higher understanding levels. Gestures and speech are more synchronized in time as children are older. A higher score on schools' language tests is related to speech attracting gestures more rigidly and more asymmetry between gestures and speech, only for the less difficult understanding levels. A higher score on math or past science tasks is related to less asymmetry between gestures and speech. The picture that emerges from our analyses suggests that the relation between gestures, speech and cognition is more complex than previously thought. We suggest that temporal differences and asymmetry in influence between gestures and speech arise from simultaneous coordination of synergies.

The high prevalence of protein-energy malnutrition is a critical issue for patients with chronic kidney disease (CKD). Serum albumin is the most commonly used nutritional marker. Another index is plasma amino acid (AA) profile. Of these, the plasma levels of glutamine, glutamate and homocysteine, correlate well with nutritional status. We measured some plasma AAs in children with different stages CKD to provide information in monitoring the therapeutic strategy, particularly in AA supplementary therapy or protein restriction. Three amino acids were evaluated along with albumin and high sensitivity C-reactive protein (hs-CRP) in 30 patients with advanced CKD stages 4 and 5. They were divided into two groups undergoing conservative treatment (CT) (n=15) or hemodialysis (HD) (n=15). An additional group of patients with nephrotic syndrome [CKD stage 2] was also studied to assess the alterations of plasma free amino acids with the early stage of CKD. Another 30 age- and sex-matched healthy children served as controls. A significant increase in plasma concentration of amino acid glutamine was observed in children with advanced CKD stages 4 and 5 when compared with controls (P=0.02).Plasma glutamine level was significantly higher in ESRD children on HD than in children with nephrotic syndrome (P=0.02). We did not find a significant difference between HD children and CT children as regard to glutamine level. Notable differences were in the plasma homocysteine level detected in the CKD groups patients, which was greater than that in controls (P=0.0001). Plasma homocysteine level was significantly higher in children on HD than in children with nephrotic syndrome (P=0.01). A significant differences was observed in hs-CRP levels between the CKD groups and the controls (P=0.04). Albumin levels were lower in CKD groups than in controls (p=0.01). Glutamine showed significant positive correlations with blood urea level (r=0.84, P=0.002) and blood ammonia level (r=0.72, P=0.0001). On multiple linear regression, urea was the only variable independently associated with an elevated plasma glutamine level (Beta=0.77, P=0.02). This study indicates that the advanced stages of CKD are associated with increased plasma concentrations of glutamine and homocysteine. Glutamine retained in the plasma of children with CRF, possibly producing higher levels of the waste products (urea and NH3). Dialysis alone is insufficient to redress completely the abnormalities in AA metabolism in ESRD children. Careful consideration of dialysis and dietary measures are necessary.

Pediatric obstructive sleep apnea (OSA) leads to multiple end-organ morbidities that are mediated by the cumulative burden of oxidative stress and inflammation. Because not all children with OSA exhibit increased systemic inflammation, genetic and environmental factors may be affecting patterns of DNA methylation in genes subserving inflammatory functions. DNA from matched children with OSA with and without high levels of high-sensitivity C-reactive protein (hsCRP) were assessed for DNA methylation levels of 24 inflammatory-related genes. Primer-based polymerase chain reaction assays in a case-control setting involving 47 OSA cases and 31 control subjects were conducted to confirm the findings; hsCRP and myeloid-related protein (MRP) 8/14 levels were also assayed. Forkhead box P3 (FOXP3) and interferon regulatory factor 1 (IRF1) showed higher methylation in six children with OSA and high hsCRP levels compared with matched children with OSA and low hsCRP levels (P < 0.05). In the case-control cohort, children with OSA and high CRP levels had higher log FOXP3 DNA methylation levels compared with children with OSA and low CRP levels and control subjects. IRF1 did not exhibit significant differences. FOXP3 DNA methylation levels correlated with hsCRP and MRP 8/14 levels and with apnea-hypopnea index (AHI), BMI z score, and apolipoprotein B levels. A stepwise multiple regression model showed that AHI was independently associated with FOXP3 DNA methylation levels (P < 0.03). The FOXP3 gene, which regulates expression of T regulatory lymphocytes, is more likely to display increased methylation among children with OSA who exhibit increased systemic inflammatory responses. Thus, epigenetic modifications may constitute an important determinant of inflammatory phenotype in OSA, and FOXP3 DNA methylation levels may provide a potential biomarker for end-organ vulnerability.

Urinary and cerebrospinal fluid (CSF) levels of 8-hydroxydeoxyguanosine (8-OHdG) were examined to estimate the relevance of oxidative stress in children with brain damage. Urinary 8-OHdG levels were measured in 51 children with various forms of central nervous system (CNS) disorders (status epilepticus [SE], hypoxic-ischemic encephalopathy [HIE], CNS infections and chronic epilepsy) and these levels were compared with those in 51 healthy children. CSF 8-OHdG levels were measured in 25 children with brain damage and in 19 control subjects. In addition, urinary and CSF levels of 8-OHdG were compared between the children with brain damage and healthy children. Finally, the relationship between urinary and CSF levels of 8-OHdG was determined in 12 children that provided both urinary and CSF samples. Our results showed that urinary 8-OHdG levels in children with HIE and CNS infections were higher than those of controls (Steel test; p < 0.05 and p < 0.05, respectively) and that CSF 8-OHdG levels were higher in children with SE, HIE, and CNS infections than in control subjects (Steel test; p < 0.01, 0.05 and 0.05, respectively). In addition, a positive correlation between the levels of urinary and CSF 8-OHdG was noted in the 12 children that provided both CSF and urinary samples (Spearman's rank correlation; rho = 0.82, p < 0.01). Further, we observed changes in the urinary 8-OHdG in a patient with HHV-6 encephalopathy, and found that the changes correlated well with the patient's clinical condition. These results suggest that oxidative stress is strongly related to acute brain damage in children, and that 8-OHdG is a useful marker of brain damage. Therefore, repeated measurements of urinary 8-OHdG may be helpful in estimating the extent of brain damage.

Teachers' dispositional mindfulness and the quality of their relationships with children in Head Start classrooms.

The quality of teachers' relationships with children is a key predictor of children's later social emotional competence and academic achievement. Interventions to increase mindfulness among teachers have focused primarily on the impacts on teachers' subjective well-being, but not on the quality of their relationships with children. Furthermore, none of these interventions have involved preschool teachers. To consider the potential of mindfulness-based interventions to improve the quality of teachers' relationships with preschool-aged children, we examined data from an online survey of 1001 classroom teachers in 37 Pennsylvania Head Start Programs. Using path analysis we investigated the association between teachers' dispositional mindfulness and the quality of their relationships with children (conflict and closeness). We further examined whether this association was mediated by teacher depressive symptoms and moderated by perceived workplace stress. Higher levels of dispositional mindfulness among teachers were associated with higher quality relationships with children (less conflict and greater closeness). The association between greater dispositional mindfulness and less conflict was partially mediated by lower depressive symptoms, and the conditional direct effect of mindfulness on conflict was stronger when perceived workplace stress was lower. These findings suggest that preschool teachers who have higher levels of dispositional mindfulness may experience higher quality relationships with children in their classrooms. Interventions to increase levels of dispositional mindfulness among early childhood educators may improve their well-being along with the quality of their relationships with children, potentially impacting children's educational outcomes. The potential impacts of such interventions may be even stronger if structural and systemic changes are also made to reduce workplace stress.

HsCRP protein is known as a novel marker of low grade inflammatory state, which characterises an atherosclerotic process in its early stages. Contrary to a large amount of data on inflammatory markers in diabetes type 2 and metabolic syndrome in adults, little is known so far about the inflammatory process in diabetes type 1, especially in children. The aim of the study was to estimate the level of hsCRP protein in children and adolescents with diabetes type 1 depending on coexisting additional risk factors for atherosclerosis and microvascular complications. 127 children and adolescents with diabetes duration 6.7+/-3.3 years, aged 14.9+/-3.1, were studied. The control group consisted of 52 healthy children aged 14.9+/-2.8 years, matched acc. to gender. HsCRP level was assessed with use of immunoturbidymetric, latex augmented method (Tina-quant CRP (Latex) HS, Roche). HsCRP in the whole study group was nearly significantly higher compared to control group: 0.17+/-0.2 vs. 0.078+/-0.1 mg/dl, p=0.072. In diabetic hypertensive children (n=38) we found significantly higher levels of hsCRP compared to controls (0.27+/-0.3 vs. 0.07 mg/dl, p=0.008) and compared to diabetic normotensive children (0.13+/-0.22 mg/dl; p=0.024). Diabetic obese patients (n=23) had significantly higer hsCRP compared to controls (0.24+/-0.3 vs. 0.07+/-0.1 mg/dl, p=0.04). In 14 studied diabetic children we found coexisting hypertension and obesity, and we found further increase in hsCRP level - 0.28+/-0.3 mg/dl. In diabetic children with microangiopathy hsCRP level was 0.22+/-0.2 mg/dl, and it was insignificantly higher compared to controls and to diabetic children without complications. Correlation analysis showed interrelations between hsCRP and systolic blood pressure (r=0.2; p=0.04) and HbA1c (r=0.25; p=0.015). In stepwise regression analysis hsCRP was related to systolic blood pressure, HbA1c and the triglycerides level (R=0.37; p=0.003). In children and adolescents with diabetes type 1 we proved significantly higher levels of hsCRP in case of a coexistence of hypertension and/or obesity. Elevated hsCRP in children with diabetes type 1 and hypertension and/or obesity reflects low grade inflammatory state in the course of metabolic syndrome.

To assess the protective role of breast-feeding in infants with CMPA-related AEDS as well as IL-10 utility as marker of disease evolution. 64 breast-feeding children with CMPA-related AEDS (31 males and 33 females; mean age 5.56±2.41months; 21 mild AEDS; 25 moderate AEDS; 18 severe AEDS) and 60 artificial feeding babies (33 males and 27 females; mean age 6.01±2.08months; 26 mild AEDS; 19 moderate AEDS; 15 severe AEDS) were evaluated. In all patients serum IL-10 levels were detected. Significant Score Atopic Dermatitis (SCORAD) index point differences between breastfed and not breastfed children (p<0.001) have been detected. The serum IL-10 levels were lower in children with CMPA-related AEDS as compared to the healthy control group (p<0.001). Moreover, a significant inverse correlation between serum IL-10 levels and SCORAD in both enrolled groups has been also noted. In particular, IL-10 levels, in both groups, were significantly lower in children with severe symptoms. Conversely, serum IL-10 levels were significantly increased in children with mild-severe symptoms in both groups. Furthermore, breastfed children, with lower severe symptoms, had higher serum IL-10 levels. Finally, serum total IgE levels were negatively correlated with serum IL-10 levels in both breastfed and non-breastfed children with CMPA-related AEDS (p<0.001). We reported that exclusive breast-feeding induces hyposensitization in children with CMPA-related AEDS and it is associated with minor disease severity and higher serum IL-10 levels, resulting as useful disease-monitor marker.

To evaluate Chinese children's blood lead levels (BLLs) and identify its distribution features, we collected articles on children's BLLs published from 1994 to March 2004 using the Chinese Biomedical Disc and reviewed 32 articles eligible for the following criteria: (1) BLLs measured by Graphite Furnace Atomic Absorption Spectroscopy or Inductively Coupled Plasma-Mass Spectrometry; (2) strict quality control; (3) no lead pollution sources in the areas where the screened subjects live; and (4) sample size bigger than 100. We found that mean BLLs of Chinese children was 92.9 {mu}g/L (37.2-254.2 {mu}g/L), and 33.8% (9.6-80.5%) of the subjects had BLLs higher thanmore » 100 {mu}g/L. Nine of the 27 provinces or cities reported had average BLLs {>=}100 {mu}g/L. Boys' BLL was 96.4 {mu}g/L, significantly higher than girls' 89.4 {mu}g/L (P<0.001). BLLs of children {<=}6 years increased with age. The mean BLLs of children living in industrial and urban areas were significantly higher than those of children in suburbs and rural areas. Our results suggested that children's BLLs in China are higher than those of their counterparts in other countries due to its heavy lead pollution. Therefore, this is of great public health importance.« less

Stress, cortisol and well-being of caregivers and children in home-based child care: a case for differential susceptibility.

PubMed

Groeneveld, M G; Vermeer, H J; van IJzendoorn, M H; Linting, M

2012-03-01

We examined whether children cared for by stressed caregivers show lower socio-emotional well-being and more stress, compared with children cared for by less stressed caregivers. Perceived stress and cortisol levels of professional caregivers (n = 44), and associations with children's (n = 44) well-being and cortisol levels in home-based child care were examined. Caregiver perceived stress and cortisol levels were related to children's well-being but not to children's cortisol levels. Children's social fearfulness acted as a moderator between caregivers' mean ratio of diurnal change in cortisol and children's well-being. When caregiver cortisol levels decreased, more fearful children were reported higher on well-being than less fearful peers. In contrast, when caregiver cortisol levels increased, more fearful children were reported lower on well-being. The findings point to differential susceptibility. Child care organizations and parents need to notice that a non-stressful child care environment is in particular important for children with a difficult temperament. © 2010 Blackwell Publishing Ltd.

ADHD severity as it relates to comorbid psychiatric symptomatology in children with Autism Spectrum Disorders (ASD).

2017-01-01

Comorbid diagnoses identified in pediatric samples have been correlated with a range of outcomes, including greater levels of emotional, behavioral, and educational impairment and the need for more intensive treatment. Given that previous research has documented high levels of comorbid Attention-Deficit/Hyperactivity Disorder (ADHD) in children with Autism Spectrum Disorders (ASD), this study closely examines the relationship between parent-reported ADHD symptoms (i.e., Conners' Parent Rating Scale, Revised [CPRS-R]) and the prevalence of additional comorbid psychiatric diagnoses in a pediatric ASD sample (n=99). Regression analyses revealed that greater severity of ADHD symptomatology was significantly related to a greater number of comorbid psychiatric diagnoses, as identified using the Diagnostic Interview for Children and adolescents, 4th Edition (DICA-IV). Additionally, more severe ADHD symptoms were also associated with higher levels of symptom severity on Child Behavior Checklist (CBCL) syndrome subscales. Interestingly, increasing severity of ASD symptomatology, as measured by the Autism Diagnostic Interview, Revised (ADI-R), was not associated with a higher prevalence of comorbid psychiatric diagnoses or CBCL syndrome severity. Our study concluded that higher levels of ADHD severity-not ASD severity-were associated with a higher prevalence of comorbid psychiatric symptomatology in school-age children with ASD. These findings may encourage clinicians to thoroughly assess ADHD symptomatology in ASD children to better inform treatment planning. Copyright © 2016 Elsevier Ltd. All rights reserved.

Limited quality of social relations, milder symptom severity and higher intelligence were shown to account for higher anxiety levels in autism spectrum disorders. The current study replicated and extended earlier findings by combining these three determinants of anxiety in autism spectrum disorders in one study. The sample consisted of 134 school-aged children with autism spectrum disorders, of whom 58 (43%) had a co-morbid anxiety disorder according to the Diagnostic Interview Schedule for Children-Parent version. In this sample, we tested associations between these determinants and anxiety univariately and multivariately to clarify the unique contribution of all determinants. Since we hypothesized that the association between limited quality of social relations and anxiety would be amplified by low symptom severity and/or high intelligence, we additionally tested for moderating effects. We found that higher anxiety levels were associated with a lower quality of social relations and lower symptom severity. In this mainly high-functioning sample, intelligence was not related to anxiety levels. No moderation effects were found. Since lower quality of social relations and lower symptom severity are associated with higher anxiety levels in children with autism spectrum disorders, therapeutic interventions aimed at reducing anxiety in autism spectrum disorders should pay attention to improving social relations, and presumably children with a lower symptom severity could benefit most from such interventions.

Bidirectional Influences of Anxiety and Depression in Young Children

PubMed Central

Hopkins, Joyce; Gouze, Karen R.; Bryant, Fred B.

2014-01-01

Anxiety and depression tend to co-occur in children. Studies indicate that higher levels of anxiety are associated with subsequent higher levels of depression, while depression may inhibit subsequent anxiety. It is important to increase our understanding of the temporal sequencing of these disorders and, particularly, to determine if suppression effects account for the inhibitory association. In addition, further information about these relationships in young children is needed. Participants were a diverse (20.4 % Hispanic, 16.7 % African American; 49.1 % boys) community sample of 796 children with data available at ages 4, 5, and 6–7 years. Anxiety and depression symptoms were assessed using the Child Symptom Inventory and symptom count measures from the Diagnostic Interview Schedule for Children-Parent Scale-Young Child version. The results indicated: (a) anxiety and depression were relatively stable over time; (b) anxiety at age 4 and 5 was a significant positive predictor of subsequent depression; (c) while an inhibitory effect of depression on subsequent anxiety was found, that inhibitory effect was due to negative suppression, and higher levels of depression were actually associated with subsequent anxiety; (e) consistent with a significant suppression effect, when depression was included as a predictor, the association between anxiety at ages 4 and 5 and anxiety one year later increases in magnitude. Both anxiety and depression are associated with higher levels of one another in the subsequent year. Implications for prevention are discussed. PMID:24934567

Some human behaviors, including aggression and activity level, differ on average for males and females. Here we report findings from two studies investigating possible relations between prenatal androgen and children's aggression and activity level. For study 1, aggression and activity level scores for 43 girls and 38 boys, aged 4 to 11years, with congenital adrenal hyperplasia (CAH, a genetic condition causing increased adrenal androgen production beginning prenatally) were compared to those of similarly-aged, unaffected relatives (41 girls, 31 boys). Girls with CAH scored higher on aggression than unaffected girls, d=0.69, and unaffected boys scored higher on activity level than unaffected girls, d=0.50. No other group differences were significant. For study 2, the relationship of amniotic fluid testosterone to aggression and activity level was investigated in typically-developing children (48 girls, 44 boys), aged 3 to 5years. Boys scored higher than girls on aggression, d=0.41, and activity level, d=0.50. However, amniotic fluid testosterone was not a significant predictor of aggression or activity level for either sex. The results of the two studies provide some support for an influence of prenatal androgen exposure on children's aggressive behavior, but not activity level. The within-sex variation in amniotic fluid testosterone may not be sufficient to allow reliable assessment of relations to aggression or activity level. Copyright © 2017 Elsevier Inc.

We examined parenting stress and mental health status in parents of autistic children and assessed factors associated with such stress. Participants were parents of 188 autistic children diagnosed with DSM-IV criteria and parents of 144 normally developing children. Parents of autistic children reported higher levels of stress, depression, and anxiety than parents of normally developing children. Mothers of autistic children had a higher risk of depression and anxiety than that did parents of normally developing children. Mothers compared to fathers of autistic children were more vulnerable to depression. Age, behavior problems of autistic children, and mothers' anxiety were significantly associated with parenting stress.

Coping with birthparent loss in adopted children.

Smith, Daniel W; Brodzinsky, David M

2002-02-01

Relationships among adopted children's appraisals of birthparent loss, their coping strategies for managing such loss, and child and parent reports of child adjustment were investigated within the context of a stress and coping model of adoption adjustment. Eighty-two 8-12-year-old adopted children and one of their parents participated. Children completed questionnaires assessing their negative affect about birthparent loss, their curiosity about birthparents, their use of coping strategies to manage birthparent-related distress, and their levels of depression, anxiety, and global self-worth. Parents reported on children's externalizing and internalizing behavior problems and social competence. Children who reported higher levels of negative affect about birthparent loss also reported higher levels of depression and lower self-worth. Curiosity about birthparents predicted parent-rated externalizing behavior. Behavioral avoidant coping was associated with greater self-reported anxiety and parent-rated externalizing behavior, whereas problem solving coping was associated with increased parent-rated social competence. The findings, though limited by issues of measurement and sampling, add to the knowledge base regarding adopted children's appraisal and coping behaviors, and provide partial support for a stress and coping model of adopted children's adjustment.

The influence of maltreatment history and out-of-home-care on children's language and social skills.

Lum, Jarrad A G; Powell, Martine; Snow, Pamela C

2018-02-01

This study examined the extent to which maltreatment history and the characteristics of out-of-home care correlated with the language and social skills of maltreated children. Participants in this study were 82 maltreated children aged between 5 and 12 years of age. All children were residing with state-designated carers in out-of-home-care. The children were presented with standardised tests assessing language and social skills. Results showed that the sample performed significantly below the normative mean on both tests. Correlation analyses showed social skills, but not language skills were correlated with aspects of maltreatment history. The education level of the state-designated carer/s was correlated with the children's language skills; higher education level was associated with higher language skills. The study provides evidence that at the group level, language and social skills are poor in maltreated children. However, gains in language skills might be made via the out-of-home-care environment. Improvements in the social skills of maltreated children may require additional support. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

Lead exposure among small-scale battery recyclers, automobile radiator mechanics, and their children in Manila, the Philippines

Blood lead (PbB) and hemoglobin levels (Hb) were determined in 40 battery repair/recycling shop workers, 16 radiator repair shop workers, and 20 children living in the immediate vicinity of these shops. Unexposed residents with similar socio-economic status were also investigated. Mean PbB level was significantly higher for battery workers when compared to radiator workers and unexposed adults. Among battery workers, 94% had PbB levels above the WHO permissible exposure limit of 40 {micro}g/dL for males and 30 {micro}g/dL for females. There was no demarcation between workplace and living quarters; therefore, workers' families were similarly exposed to hazards. Children living inmore » the immediate vicinity of battery shops also had significantly higher mean PbB levels compared to radiator shop children and unexposed children. For workers with PbB > 40 {micro}g/dL, 90% were anemic. Linear regression showed a correlation between Hb level and log{sub 10}PbB. There was no significant relationship between anemia and blood lead in children. The authors conclude that radiator repair activities appeared to increase the body burden of lead, although not up to a level significantly different from unexposed counterparts. Battery recycling/repair activities, however, significantly increased blood lead levels in workers and their children.« less

Elevated lead levels and adverse effects on natural killer cells in children from an electronic waste recycling area.

2016-06-01

Lead (Pb) has been proved to exert immunotoxicity to influence immune homeostasis in humans. To monitor the internal Pb level and evaluate its effect on natural killer (NK) cells and cytokine/chemokine concentrations, we recruited 285 preschool children from Guiyu, one of the largest electronic waste (e-waste) destinations and recycling areas in the world, and known to have high concentrations of Pb in the air, soil, water, sediment and plants. A total of 126 preschool children were selected from Haojiang as a reference group. Results showed that children in Guiyu, the exposed area, had higher blood Pb levels and lower percentages of NK cells than children from the reference area. A significantly negative association was found between the percentage of NK cells and increasing Pb levels. Moreover, children in Guiyu area had higher platelet counts and IL-1β concentrations, and lower levels of IL-2, IL-27, MIP-1α and MIP-1β were observed in the exposed children. These changes might not be conducive to the development and differentiation of NK cells. Taken together, the elevated Pb levels result in the lower percentages of NK cells, but also alter the levels of platelets, IL-1β and IL-27, which might be unconducive to the activity and function of NK cells.

Asgari, M.M.; Dubois, A.; Beckett, W.S.

During the summer of 1994, a cross-sectional epidemiological study, in which the pulmonary function of children in Tehran was compared with pulmonary function in children in a rural town in Iran, was conducted. Four hundred children aged 5--11 y were studied. Daytime ambient nitrogen dioxide, sulfur dioxide, and particulate matter were measured with portable devices, which were placed in the children`s neighborhoods on the days of study. Levels of these ambient substances were markedly higher in urban Tehran than in rural areas. Children`s parents were questioned about home environmental exposures (including heating source and environmental tobacco smoke) and the children`smore » respiratory symptoms. Pulmonary function was assessed, both by spirometry and peak expiratory flow meter. Forced expiratory volume in 1 s and forced vital capacity--as a percentage of predicted for age, sex and height--were significantly lower in urban children than in rural children. Both measurements evidenced significant reverse correlations with levels of sulfur dioxide, nitrogen dioxide, and particulate matter. Differences in spirometric lung function were not explained by nutritional status, as assessed by height and weight for age, or by home environmental exposures. Reported airway symptoms were higher among rural children, whereas reported physician diagnosis of bronchitis and asthma were higher among urban children. The association between higher pollutant concentrations and reduced pulmonary function in this urban-rural comparison suggests that there is an effect of urban air pollution on short-term lung function and/or lung growth and development during the preadolescent years.« less

Perceptions of Stigma and Self-Reported School Engagement In Same-Sex Couples with Young Children.

2014-09-01

Little research has explored same-sex parents' school engagement, although there is some evidence that same-sex parents' perceptions of openness versus exclusion in the school setting -as well as other interrelated contexts - may have implications for their relationships with and perceptions of their children's schools. The current cross-sectional study used multilevel modeling to examine the relationship between same-sex parents' perceptions of stigma in various contexts and their self-reported school involvement, relationships with teachers, and school satisfaction, using a sample of 68 same-sex adoptive couples (132 parents) of kindergarten-age children. Parents who perceived their communities as more homophobic reported higher levels of school-based involvement. Parents who perceived lower levels of sexual orientation-related stigma at their children's schools reported higher levels of school satisfaction. Parents who perceived lower levels of exclusion by other parents reported higher levels of school-based involvement and better relationships with teachers. However, perceived exclusion interacted with parents' level of outness with other parents, such that parents who were very out and reported high levels of exclusion reported the lowest quality relationships with teachers. Our findings have implications for scholars who study same-sex parent families at various stages of the life cycle, as well as for teachers and other professionals who work with diverse families.

This study examines electrocortical activity associated with visual and auditory sensory perception and lexical-semantic processing in nonverbal (NV) or minimally-verbal (MV) children with Autism Spectrum Disorder (ASD). Currently, there is no agreement on whether these children comprehend incoming linguistic information and whether their perception is comparable to that of typically developing children. Event-related potentials (ERPs) of 10 NV/MV children with ASD and 10 neurotypical children were recorded during a picture-word matching paradigm. Atypical ERP responses were evident at all levels of processing in children with ASD. Basic perceptual processing was delayed in both visual and auditory domains but overall was similar in amplitude to typically-developing children. However, significant differences between groups were found at the lexical-semantic level, suggesting more atypical higher-order processes. The results suggest that although basic perception is relatively preserved in NV/MV children with ASD, higher levels of processing, including lexical- semantic functions, are impaired. The use of passive ERP paradigms that do not require active participant response shows significant potential for assessment of non-compliant populations such as NV/MV children with ASD.

To investigate the clinical symptoms and features of interictal epileptiform discharges (IED) on electroencephalogram (EEG) in children with spastic hemiplegic cerebral palsy (CP) and to analyze the risk factors for IED. Eighty-three children with spastic hemiplegic CP were recruited, and their clinical data, results of video-electroencephalogram, imaging findings, and cognitive levels were collected. The influencing factors for IED were determined by multiple logistic regression analysis. The incidence of epilepsy was 13% in children with spastic hemiplegic CP; 34% of these cases had IED. The incidence of epilepsy in children with IED (32%) was significantly higher than that in those without IED (4%) (P<0.01). The incidence of IED in children with complications and brain cortex impairment increased significantly (P<0.01). The incidence of IED varied significantly between patients with different cognitive levels (P<0.01). Brain cortex impairment (OR=11.521) and low cognitive level (OR=2.238)were risk factors for IED in children with spastic hemiplegic CP (P<0.05). Spastic hemiplegic CP is often found with IED on EEG, and the incidence of epilepsy is higher in children with IED than in those without IED. Brain cortex impairment and low cognitive level have predictive values for IED in children with spastic hemiplegic CP.

Given mixed findings as to whether stressful experiences and relationships are associated with increases or decreases in children's cortisol reactivity, we tested whether a child's developmental history of risk exposure explained variation in cortisol reactivity to an experimentally induced task. We also tested whether the relationship between cortisol reactivity and children's internalizing and externalizing problems varied as a function of their developmental history of stressful experiences and relationships. Participants included 400 children (M = 9.99 years, SD = 0.74 years) from the Children's Experiences and Development Study. Early risk exposure was measured by children's experiences of harsh, nonresponsive parenting at 3 years. Recent risk exposure was measured by children's exposure to traumatic events in the past year. Children's cortisol reactivity was measured in response to a social provocation task and parents and teachers described children's internalizing and externalizing problems. The effect of recent exposure to traumatic events was partially dependent upon a child's early experiences of harsh, nonresponsive parenting: the more traumatic events children had recently experienced, the greater their cortisol reactivity if they had experienced lower (but not higher) levels of harsh, nonresponsive parenting at age 3. The lowest levels of cortisol reactivity were observed among children who had experienced the most traumatic events in the past year and higher (vs. lower) levels of harsh, nonresponsive parenting in early childhood. Among youth who experienced harsh, nonresponsive parent-child relationships in early childhood and later traumatic events, lower levels of cortisol reactivity were associated with higher levels of internalizing and externalizing problems. Hypothalamic-pituitary-adrenal (HPA) axis reactivity to psychological stressors and the relationship between HPA axis reactivity and children's internalizing and externalizing problems vary as a function of a child's developmental history of exposure to stressful relationships and experiences. © 2014 The Authors.

Little is known about the variation of Chinese children's exposure to arsenic by geography, age, gender, and other potential factors. The main objective of this study was to investigate the total arsenic concentration in Chinese children's urine by geographic locations, ages, and genders. In total, 259 24-h urine samples were collected from 210 2- to 12-year-old children in China and analyzed for total arsenic and creatinine concentrations. The results showed that the upper limit (upper limit of the 90% confidence interval for the 97.5 fractile) was 27.51 µg/L or 55.88 µg/g creatinine for Chinese children. The total urinary arsenic levels were significantly different for children in Guangdong, Hubei, and Gansu provinces (P < 0.05), where the upper limits were 24.29, 58.70, and 44.29 µg/g creatinine, respectively. In addition, the total urinary arsenic levels were higher for 2- to 7-year-old children than for 7- to 12-year-old children (P < 0.05; the upper limits were 59.06 and 44.29 µg/g creatinine, respectively) and higher for rural children than for urban children (P < 0.05; the upper limits were 59.06 and 50.44 µg/g creatinine, respectively). The total urinary arsenic levels for boys were not significantly different from those for girls (P > 0.05), although the level for boys (the upper limit was 59.30 µg/g) was slightly higher than that for girls (the upper limit was 58.64 µg/g creatinine). Because the total urinary arsenic concentrations are significantly different for general populations of children in different locations and age groups, the reference level of total urinary arsenic might be dependent on the geographic site and the child's age.

To calculate indices of inequality and inequity in the use of medical services for children, adults, and older adults in Chile from 2000 to 2011. Based on the CASEN survey (2000-2011), the concentration index (CI) was calculated to measure inequality and the horizontal inequity index (HI) was calculated to measure inequity in the use of medical services. Four groups were studied: children under 5, children aged 6-18 years, adults, and older adults. The results indicate higher levels of inequality in the use of specialized physician services in the child groups, and higher levels of inequity in the adult group. In the use of dental services, the greatest inequality and inequity is found among older adults. For visits to emergency services in the last two years for which data are available (2009 and 2011), the adult group shows a higher level of inequality. In terms of levels of inequity and inequality, there are differences among children, adults, and older adults over the years in at least three of the six variables studied.

To compare oxidative status, total antioxidant capacity and values of DNA damage in peripheral blood lymphocytes in children exposed to secondhand cigarette smoke with healthy controls. Analytical, Observational. 54 children without any chronic diseases, attending the healthy child monitoring polyclinic. These comprised 27 children who had been exposed to passive cigarette smoke and 27 children who had not been exposed to cigarette smoke. Urine cotinine levels by the chemiluminescent technique; DNA damage by alkaline comet assay; and total oxidant status (TOS) using a novel automated measurement method. The mean urine cotinine, TOS, Oxidative Stress Index (OSI) and DNA damage values of the group exposed to cigarette smoke were determined to be at significantly higher level compared to the group not exposed to cigarette smoke (P<0.001). No statistically significant difference was determined in the TAS level between the two groups (P=0.1) The results showed that TOS levels, OSI index and DNA damage in peripheral blood lymphocytes were significantly higher in children exposed to secondhand cigarette smoke than in those not exposed to secondhand cigarette smoke.

Afro-Ecuadorian individuals from an area where Onchocerca volvulus is hyperendemic have been monitored for infection over the past 16 years. To determine whether in utero exposure to O. volvulus biases a child's subsequent immune responses, children (9 to 16 years old) for whom the mother's infection status was known were chosen for study. Children of infected mothers (n = 19) had significantly higher levels of skin microfilariae than children of uninfected mothers (n = 13; P = 0.021). While the serum levels of O. volvulus-specific immunoglobulin G (IgG), IgG subclasses, and IgE showed no significant differences between the two groups of children, peripheral blood mononuclear cells of children of infected mothers produced higher levels of Th2-type cytokines to several parasite antigens and lower levels of Th1-type cytokines to nonparasite antigens than those of children of uninfected mothers. Thus, in utero exposure to O. volvulus has a long-term effect on the child's subsequent cellular immune response that may render the child more susceptible to O. volvulus infection postnatally.

The effect of serum folate levels and methylenetetrahydrofolate reductase (MTHFR) genotype on complications and outcome of induction chemotherapy in 150 children with acute lymphoblastic leukemia (ALL) was studied. Folate deficiency in 26% at baseline was more common in children with MTHFR 677 mutations. Folate deficient children had a higher incidence of neutropenia (p = 0.03), thrombocytopenia (p = 0.02) and febrile neutropenia (p = 0.01) and higher transfusion requirement during induction compared to folate sufficient children. Sepsis related induction deaths were more frequent in folate deficient children (p = 0.02) during induction. Children with 677 and 1298 mutations had a higher incidence of cytopenias (p = 0.01) and mucositis (p = 0.007), the risks of which increased with concomitant folate deficiency. A significant fall in folate levels was observed post-induction (p = 0.02), most markedly in mutant 677 genotypes. Multivariate analysis revealed associations of baseline folate deficiency with low counts at day 14 (p = 0.001) and MTHFR 1298 mutations with mucositis (p = 0.02).

To explore the relationship between gross motor and intellectual function in children with cerebral palsy (CP). A cross-sectional study. Occupational therapy clinic. Children with CP (N=662; 281 girls, 381 boys; age range, 3-14y). Not applicable. Intelligence testing was carried out by means of the Wechsler Preschool and Primary Scale of Intelligence and the Wechsler Intelligence Scale for Children-Revised. Gross motor function level was determined by the Gross Motor Function Classification System Expanded and Revised (GMFCS E&R). Of the children, 10.4% were at level I of the GMFCS E&R, 38% at levels II and III, and 51.5% at levels IV and V. The lowest level of intelligence or profound intellectual disability was found in children with spastic quadriplegia (n=28, 62.2%). Children at the lowest levels (I-IV, GMFCS E&R) obtained higher ratings in terms of intelligence in comparison with children at level V. Based on the present results, the diagnosis was statistically related to the intellectual level as dependent variable (P<.01); accordingly, hypotonic, quadriplegic, and hemiplegic patients had the highest odds to assign higher ratings in abnormal intelligence, respectively. Sex and age were not statistically related to the dependent variable. The study results demonstrated a significant association between GMFCS E&R and intellectual function. Therefore, we suggest that particular attention should be paid to the intellectual level in terms of evaluations of gross motor function. These results, in respect, might be interested for occupational and physical therapists who are involved in rehabilitation programs for these children.

Left-behind children refer to those rural children who are under 18 years of age and are left at home when both or one of their parents migrate to urban area for work. Recent findings showed that left-behind children were disadvantaged by developmental, emotional and social problems. A sample of 1165 rural children and adolescents were recruited to examine the characteristics of left-behind children and explore the differences in psychological adjustment (including satisfaction, loneliness and happiness) by patterns of parental migration (i.e. no parent migrating, one parent migrating or two parents migrating) and the level of parent-child communication in rural China. (1) Compared with children with one parent migrating, children with two parents migrating were separated from their parents at younger ages, for longer periods, and saw their migrant parents less frequently. (2) Children with two parents migrating reported the lowest level of satisfaction among the three groups of rural children. Both groups of children with one or two parents migrating experienced more loneliness compared with children with no parent migrating. There were no significant differences in school satisfaction and happiness among the three groups. (3) The children who reported a higher level of parent-child communication also reported a higher level of life and school satisfaction and happiness, and no differences in loneliness were found by levels of parent-child communication. These results indicate that loneliness was the most common and important experience of left-behind children. Parent-child communication is important for the development of all rural children, including those who were left behind by their migrant parents. © 2012 Blackwell Publishing Ltd.

The Patient Protection and Affordable Care Act (ACA) includes subsidies that reduce patient cost sharing for low-income families. Limited information on the effects of cost sharing among children is available to guide these efforts. To examine the associations between cost sharing, income, and care seeking and financial stress among children with asthma. A telephone survey in 2012 about experiences during the prior year within an integrated health care delivery system. Respondents included 769 parents of children aged 4 to 11 years with asthma. Of these, 25.9% of children received public subsidies; 21.7% were commercially insured with household incomes at or below 250% of the federal poverty level (FPL) and 18.2% had higher cost-sharing levels for all services (e.g., ≥$75 for emergency department visits). We classified children with asthma based on (1) current receipt of a subsidy (i.e., Medicaid or Children's Health Insurance Program) or potential eligibility for ACA low-income cost sharing or premium subsidies in 2014 (i.e., income ≤250%, 251%-400%, or >400% of the FPL) and (2) cost-sharing levels for prescription drugs, office visits, and emergency department visits. We examined the frequency of changes in care seeking and financial stress due to asthma care costs across these groups using logistic regression, adjusted for patient/family characteristics. Switching to cheaper asthma drugs, using less medication than prescribed, delaying/avoiding any office or emergency department visits, and financial stress (eg, cutting back on necessities) because of the costs of asthma care. After adjustment, parents at or below 250% of the FPL with lower vs higher cost-sharing levels were less likely to delay or avoid taking their children to a physician's office visit (3.8% vs. 31.6%; odds ratio, 0.07 [95% CI, 0.01-0.39]) and the emergency department (1.2% vs. 19.4%; 0.05 [0.01-0.25]) because of cost; higher-income parents and those whose children were receiving public subsidies (eg, Medicaid) were also less likely to forego their children's care than parents at or below 250% of the FPL with higher cost-sharing levels. Overall, 15.6% of parents borrowed money or cut back on necessities to pay for their children's asthma care. Cost-related barriers to care among children with asthma were concentrated among low-income families with higher cost-sharing levels. The ACA's low-income subsidies could reduce these barriers for many families, but millions of dependents for whom employer-sponsored family coverage is unaffordable could remain at risk for cost-related problems because of ACA subsidy eligibility rules.

To investigate the major influence factors of child neglect among rural areas children aged 3-6 years in China. According to multi-stage stratified cluster sampling, distribution characteristics and the level of economic development, we randomly sampled 10 provinces, 26 cities (8 capital cities, 16 prefecture-level cities and 2 municipalities) using lottery method. Depending on the different level of economic and cultural, we sampled one medium county from each city (municipalities sampled two counties), a total of 28 counties. All towns were divided into high, medium and low three levels in accordance with economic and cultural, each level sampled one town, each conty sampled three towns, a total of 84 towns were sampled. Each town sampled 40 children, including 20 boys and 20 girls (including each 10 children aged 3 to 6, half and half boys and girls). 4 096 rural children aged 3-6 years old were sampled and surveyed of China. Based on "the Neglect Norms for Children Aged 3 to 6 Years Old in Rural Areas of China" explored the risk factors of child neglect. SPSS 18. 0 for windows was employed for statistics analysis. Multifactorial analysis was conducted through multivariate Logistic Regression. The total neglected rate of the rural children aged 3 to 6 was 53.7% (2,047/3,810), and the total neglected degree was 44.42±7.57. The multivariate logistic regression analysis showed that, neglected risk of the boys was higher than the girls (OR=1.30, 95% CI: 1.13-1.49), neglected risk of children were higher, when their mothers were migrant workers (OR=2.18, 95% CI: 1.59-3.00); the lower educational level of mothers, the higher neglected risk of children, the children in families that mothers only received primary education or was uneducated were most likely to be neglected (OR=2.92, 95% CI: 1.91-4.47), the second was the families that mothers received primary education (OR=1.86, 95% CI: 1.29-2.69); the lower the household income, the easier to be neglected the children, the easiest one was the household income less than 5000 RMB (OR=2.85, 95% CI: 2.14-3.79), the second was 5000-9,999 RMB (OR=1.76, 95% CI: 1.40-2.20); the relationship between children and mothers was distanced, neglect risk of children was higher (OR=3.88, 95% CI: 1.31-11.52); left behind children were easier to be neglected (OR=1.30, 95% CI: 1.09-1.54). The influence factors among children aged 3-6 years in the rural areas of China were boys, mother's occupation, maternal education level, the relationship between children and mothers, household income and left-behind children.

The present study investigated demographic differences in school readiness within Jordan, a particularly interesting context because of wide-spread national reform currently sweeping the education system in Jordan. Teacher reports and researcher direct assessments of the school readiness of a national sample of 4,681 Jordanian first grade children were used to describe the levels of school readiness of children with respect to seven demographic characteristics. Higher levels of school readiness were associated with male gender, higher family income, higher paternal education, higher maternal education, smaller family size, fewer siblings, and urban residence. Taken together, the findings highlight the importance of Jordanian education reform, one aim of which is to improve the school readiness of all children by implementing public kindergartens, especially in poor, rural areas.

Elevated blood lead levels (BPbs) have been identified in Uruguayan children in the La Teja neighborhood of Montevideo, but the extent of lead exposure in other city areas is unknown. Sources and predictors of exposure also remain understudied in this population. In 2007, the authors screened lead and hemoglobin levels in capillary blood of 222 preschool children from several areas of Montevideo, Uruguay, and identified predictors of elevated BPbs. Mean BPb was 9.0 +/- 6.0 microg/dL and 32.9% of children had levels >or= 10microg/dL. Mean hemoglobin level was 10.5 +/- 1.5 g/dL, with 44.1% having levels <10.5g/dL. Older child age, hemoglobin <10.5g/dL, and putting fingers/toys in the mouth were associated with higher BPbs. Young maternal age, less education, father's job with potential risk of lead exposure, and fewer family possessions were also associated with higher BPbs. Pediatric lead exposure is a public health problem in Uruguay, with children experiencing elevated BPbs at a young age.

A positive relation between exhaled nitric oxide (NO) levels and allergen exposure has been found in some studies whereas there is less information on how non-allergen environmental factors influences exhaled NO. To study the relationship between exhaled NO levels in schoolchildren in relation to IgE sensitisation and allergenic and non-allergenic environmental factors. This study comprised 374 schoolchildren (13-14 years of age) who performed exhaled NO-measurements and skin prick tests. Exposure to allergens, respiratory infections, environmental tobacco smoke and home window pane condensation, the latter an indicator of high humidity and poor ventilation was evaluated through questionnaires. In IgE-sensitised children sensitisation to pets was a more important determinant of exhaled NO than sensitisation to pollen. Higher NO levels were found in cat-sensitised children with a cat or other furred pets at home compared to cat-sensitised children without pets (geometric mean, 24.0 vs. 13.9 ppb, P=0.03). Significantly higher exhaled NO levels were found in non-sensitised children that reported having a cold (5.7 vs. 3.8 ppb, P<0.001) or lived in homes with window pane condensation (7.1 vs. 4.4 ppb, P=0.01) than in non-sensitised children without a cold and window pane condensation, respectively. These associations were not found in children that were sensitised to inhalation allergens. Allergen exposure seems to be the most important determinant for exhaled NO levels in IgE-sensitised children whereas in non-sensitised children NO levels were associated with respiratory infections and home window pane condensation.

Even though sepsis is one of the common causes of children morbidity and mortality, specific inflammatory markers for identifying sepsis are less studied in children. The main aim of this study was to compare the levels of high-mobility group box-1 protein (HMGB1), Lipopolysaccharide-binding protein (LBP), Interleukin-6 (IL-6) and C-reactive protein (CRP) between infected children without systemic inflammatory response syndrome (SIRS) and children with severe and less severe sepsis. The second aim was to examine HMGB1, LBP, IL6 and CRP as markers for of bacteraemia. Totally, 140 children with suspected or proven infections admitted to the Children's Clinical University Hospital of Latvia during 2008 and 2009 were included. Clinical and demographical information as well as infection focus were assessed in all patients. HMGB1, LBP, IL-6 and CRP blood samples were determined. Children with suspected or diagnosed infections were categorized into three groups of severity of infection: (i) infected without SIRS (n = 36), (ii) sepsis (n = 91) and, (iii) severe sepsis (n = 13). They were furthermore classified according bacteraemia into (i) bacteremia (n = 30) and (ii) no bacteraemia (n = 74). There was no statistically significant difference in HMGB1 levels between children with different levels of sepsis or with and without bacteraemia. The levels of LBP, IL-6 and CRP were statistically significantly higher among patients with sepsis compared to those infected but without SIRS (p < 0.001). Furthermore, LBP, IL-6 and CRP were significantly higher in children with severe sepsis compared to those ones with less severe sepsis (p < 0.001). Median values of LBP, IL6 and CRP were significantly higher in children with bacteraemia compared to those without bacteraemia. The area under the receiver operating curve (ROC) for detecting bacteraemia was 0.87 for both IL6 and CRP and 0.82 for LBP, respectively. Elevated levels of LBP, IL-6 and CRP were associated with a more severe level of infection in children. Whereas LBP, IL-6 and CRP seem to be good markers to detect patients with bacteraemia, HMGB1 seem to be of minor importance. LBP, IL-6 and CRP levels may serve as good biomarkers for identifying children with severe sepsis and bacteraemia and, thus, may be routinely used in clinical practice.

Polymorphisms in the NAMPT gene, which encodes the adipocytokine visfatin/nicotinamide phosphorybosil transferase (NAMPT), affect the circulating visfatin/NAMPT levels and are associated with obesity and cardiovascular diseases. However, no study has tested the hypothesis that NAMPT haplotypes could affect visfatin/NAMPT levels in case of childhood obesity. We investigated the effects of traditional metabolic risk factors (MRFs) and NAMPT polymorphisms T/C (rs1319501) and A/G (rs3801266) or haplotypes on visfatin/NAMPT levels in obese children and adolescents, and whether NAMPT polymorphisms and/or haplotypes are associated with susceptibility to childhood obesity. We studied 175 control, 99 obese and 82 obese with ⩾ 3 MRFs children and adolescents. Genotypes were determined by a Taqman allele discrimination assay and real-time PCR. The plasma visfatin/NAMPT level was measured using an enzyme immunoassay. Obese children and adolescents with ⩾ 3 MRFs had higher plasma visfatin/NAMPT levels in comparison with control children and adolescents (P<0.05). Although positive associations were observed between visfatin/NAMPT and body mass index (rs = 0.157; P = 0.034) as well as visfatin/NAMPT and waist circumference (rs = 0.192; P = 0.011), visfatin/NAMPT and high-density lipoprotein cholesterol were inversely associated (rs = -0.162; P = 0.031). No significant differences in genotype, allele or haplotype frequency distributions for the studied polymorphisms were found when the three groups were compared. However, higher plasma visfatin/NAMPT levels were found in control and obese subjects carrying the GG genotype for the A/G (rs3801266) polymorphism (P<0.05) but not in obese children with ⩾ 3 MRFs. Moreover, control subjects carrying the 'T-G' haplotype showed higher plasma visfatin/NAMPT levels. NAMPT genotypes or haplotypes were not associated with childhood obesity. Obesity in children with ⩾ 3 MRFs increases plasma visfatin/NAMPT levels, and this marker was associated with body mass index and waist circumference. The A/G polymorphism and NAMPT haplotypes affect plasma visfatin/NAMPT levels in controls but not in obese children with ⩾ 3 MRFs. These results suggest that obesity and MRFs are more influential than genetic polymorphisms in the determination of visfatin/NAMPT levels in obese children. Further research is necessary to explain why the GG genotype is not associated with increased visfatin/NAMPT levels in obese children with ⩾ 3 MRFs.

Purpose Exposure to environmental tobacco smoke (ETS) leads to molecular damage in the form of DNA adducts. While lung cancer risk is higher among African Americans compared to White Americans, a few studies have tested for racial differences in DNA adducts among children exposed to ETS. The purpose of this study was to test whether African American children have higher DNA adducts levels compared to White children adjusted for ETS exposure. Methods Data and biologic specimens were drawn from an existing cohort of 212 asthmatic children. These subjects participated in a 12-month ETS-reduction trial that employed HEPA air cleaners with active filter cartridges and sham filter cartridges. White blood cell (WBC) DNA was analyzed for DNA adducts using 32P-postlabeling. We assessed ETS exposure using a validated air nicotine dosimeter. We determined the independent relationship between African American race and DNA adduct levels adjusted for ETS exposure and air cleaner use. Results The mean age of the subjects was 8.4 years; 55% were African American. There was no difference in DNA adduct levels between African American and White children (11.8 vs. 11.2 adducts per 109 nucleotides, p = 0.86), despite slightly higher levels of air nicotine exposure (3.4 vs. 2.2 μg/m3, p = 0.14). African American children used their air cleaners less often than White children. We found that the best predictor of DNA adduct levels was the duration of air cleaner use (r = −0.133, p = 0.056). This association was independent of cartridge type. Conclusions We did not see differences in adduct levels by race even after accounting for the level of ETS exposure. However, there was a marginal inverse association between air cleaner use and adducts. Additional research is required to understand this phenomenon. PMID:20336464

Effects of long-term low-level radiation exposure after the Chernobyl catastrophe on immunoglobulins in children residing in contaminated areas: prospective and cross-sectional studies

PubMed Central

2014-01-01

Background After the Chernobyl nuclear incident in 1986, children in the Narodichesky region, located 80 km west of the Chernobyl Power Plant, were exposed to 137Cesium (137Cs). Little is known about the effects of chronic low-level radiation on humoral immune responses in children residing in contaminated areas. Methods In four different approaches we investigated the effect of residential 137Cs exposure on immunoglobulins A, G, M, and specific immunoglobulin E in children. In a dynamic cohort (1993–1998) we included 617 children providing 2,407 repeated measurements; 421 and 523 children in two cross-sectional samples (1997–1998 and 2008–2010, respectively); and 25 participants in a small longitudinal cohort (1997–2010). All medical exams, blood collections, and analyses were conducted by the same team. We used mixed linear models to analyze repeated measurements in cohorts and general linear regression models for cross-sectional studies. Results Residential soil contamination in 2008 was highly correlated with the individual body burden of 137Cs. Serum IgG and IgM concentrations increased between 1993 and 1998. Children with higher 137Cs soil exposure had lower serum IgG levels, which, however, increased in the small cohort assessed between 1997 and 2010. Children within the fourth quintile of 137Cs soil exposure (266–310 kBq/m2) had higher IgM serum concentrations between 1993 and 1998 but these declined between 1997 and 2010. IgA remained stable with median 137Cs exposures related to higher IgA levels, which was corroborated in the cross-sectional study of 2008–2010. Specific IgE against indoor allergens was detected less often in children with higher 137Cs exposure. Conclusions Our findings show radiation-related alterations of immunoglobulins which by themselves do not constitute adverse health effects. Further investigations are necessary to understand how these changes affect health status. PMID:24886042

Mount Isa, Queensland, is one of three Australian cities with significant lead emissions due to nonferrous mining and smelting. Unlike the two other cities with lead mines or smelters, Mount Isa currently has no system of annual, systematic, community-wide blood lead level testing; and testing rates among Indigenous children are low. In previous screenings, this group of children has been shown to have higher average blood lead levels than non-Indigenous children. The first aim of this study was to assess whether parents and children would participate in less invasive, rapid point-of-care capillary testing. The second aim was to measure blood lead levels among a range of children that roughly reflected the percentage of the Indigenous/non-Indigenous population. This pilot study is based on a convenience sample of children between the ages of 12 and 83 months who were recruited to participate by staff at a Children and Family Centre. Over three half-days, 30 children were tested using capillary blood samples and the LeadCare II Point-of-Care testing system. Rapid point-of-care capillary testing was well tolerated by the children. Of 30 children tested, 40% ( n = 12) had blood lead levels ≥5 µg/dL and 10% had levels ≥10 µg/dL. The highest blood lead level measured was 17.3 µg/dL. The percentage of children with blood lead levels ≥5 µg/dL was higher among Indigenous children compared to non-Indigenous (64.2% compared to 18.8%) as was the geometric mean level (6.5 (95% CI, 4.7, 9.2) versus 2.4 (95% CI, 1.8, 3.1)), a statistically significant difference. Though based on a small convenience sample, this study identified 12 children (40%) of the sample with blood lead levels ≥5 µg/dL. Due to historical and ongoing heavy metal emissions from mining and smelting in Mount Isa, we recommend a multi-component program of universal blood lead level testing, culturally appropriate follow-up and intervention for children who are identified with blood lead levels ≥5 µg/dL. We further recommend focused outreach and assistance to the Indigenous community, and further control of emissions and remediation of existing environmental lead contamination in children's play and residential areas.

To assess dental caries trends in indigenous children in South Australia, 2001-2010; and contribution by area-level socioeconomic status (SES), remoteness and water fluoridation status. This study is a part of the Child Dental Health Survey (CDHS) is an ongoing national surveillance survey in Australia including children enrolled in the School Dental Services (SDS). Postcode-level adjusted mean deciduous and permanent caries experience was estimated at each year. Time trend of dental caries experience was estimated using mixed effect models. Area-level socioeconomic status, remoteness, water fluoridation status were independent variables in the models. There was a significant upward trend of dental caries experience over the 10 years. Dental caries experience of indigenous children living in low SES areas had nearly one more deciduous tooth and a half permanent tooth with caries than indigenous children living in higher SES areas. The remote postcodes showed higher levels of decay in deciduous dentition (+1.25 teeth) compared with others regions. The dental caries trend increased in South Australian indigenous children over the study period, and was associated with area-level SES and remoteness. The increasing trend in dental caries in indigenous children is important evidence to inform policies to improve oral health. © 2015 American Association of Public Health Dentistry.

The number of rural Chinese parents who leave their children with family members to work in the cities has increased dramatically over the last decade. This study compared the social anxiety of left-behind children (LBC) and children not left behind (non-LBC). We investigated 1694 LBC and 1223 non-LBC, aged seven to 17 years, in a Chinese province using a structured questionnaire that included questions about socio-demographic characteristics, social anxiety, family function, quality of life, neglect and physical abuse. LBC displayed higher social anxiety scores, more neglect, lower parental educational level, lower quality of life, lower family function and lower prevalence of physical abuse than non-LBC. Multiple linear regression models showed that higher Social Anxiety Scales for Children (SASC) scores in LBC were clearly associated with lower quality of life, poorer family function, physical abuse, being female, having more siblings and minorities. In non-LBC, they were associated with lower quality of life, poorer family function, neglect, being female and physical abuse. LBC have a relatively higher level of social anxiety and poorer living conditions than non-LBC, and there are differences in social anxiety, and its relevant factors, between the two groups. ©2014 Foundation Acta Paediatrica.

In the recent years, alterations in the carbohydrate metabolism, including insulin resistance, are considered as risk factors in the development of hypertension and its complications in young age. Hypertension is associated with significant cardiovascular morbidity and mortality. The onset of pathology responsible for the development of hypertension, as well as levels of biomarkers specific for early stages of atherosclerosis are poorly understood. To compare a group of children whose parents have a history of hypertension (study group) with a group of children with normotensive parents (reference group), with consideration of typical risk factors for atherosclerosis, parameters of lipid and carbohydrate metabolism, anthropometric data and new biomarkers of early cardiovascular disease (hsCRP, adiponectin, sICAM-1). The study population consists of 84 children. Of these, 40 children (mean age 13.6±2.7 years) had a parental history of hypertension, and 44 aged 13.1±3.7 yrs were children of normotensive parents. Anthropometric measurements were taken, and measurements of blood pressure, lipid profile, glucose and insulin levels were carried out. The insulin resistance index (HOMA IR) was calculated. Levels of hsCRP, soluble cell adhesion molecules (sICAM) and adiponectin were measured. There were no statistically significant differences in anthropometric parameters (body mass, SDS BMI, skin folds) between groups. Values of systolic blood pressure were statistically significantly higher in the study group (Me 108 vs. 100 mmHg, p= 0.031), as were glycaemia (Me 80 vs. 67 mg/dl p<0.001) and insulinaemia levels (Me 8.89 vs. 5.34 µIU/ml, p=0.024). Higher, statistically significant values of HOMA IR were found in the study group (children of hypertensive parents) (Me 1.68 vs. 0.80 mmol/l × mU/l, p=0.007). Lower adiponectin levels (Me 13959.45 vs. 16822 ng/ml, p=0.020) were found in children with a family history of hypertension. No significant differences were found in the levels of sICAM, hsCRP, and parameters of lipid metabolism. Family history of hypertension is correlated with higher values of systolic blood pressure and higher values of parameters for carbohydrate metabolism in children. Hypertension in parents is a risk factor for cardiovascular disease in their children. © Polish Society for Pediatric Endocrinology and Diabetology.

We aimed to investigate the blood lead level (BLL) in children with neurologic disorders of unknown causes and compare with normal children. In this prospective case-control study, 68 patients aged 1 to 18 yr with neurologic disorders of unknown causes, were referred to pediatric neurology clinics and wards, Shiraz, Iran selected during a 12 months period from Sep 2013. They were compared with 1:1 ratio, age, and sex-matched healthy children. BLL was checked from all participants using 3 cc heparinized venous blood sample. Level of ≥5 mcg/dl was considered toxic dose. Totally, 136 children (68 cases and 68 controls) with mean ages of 5.20±4.12 and 4.18±3.86 yr, respectively, were enrolled. Mean BLL was higher in case group than in controls but the difference was not significant ( P =0.84), though they were less than toxic levels in both. In addition, the difference in mean BLLs was not significant in terms of living place, sex, and age. Totally, 17.7% of the study sample had BLL ≥5 mcg/dl. The frequency of BLL ≥5 mcg/dl was significantly higher in case group ( P =0.024) with an odds ratio 2.9 times higher (95% CI: 1.066-7.60). Strategies in public health must focus on practicing primary and secondary preventions of lead exposure in children.

This study examined the development of aggressive and oppositional behavior among alcoholic and nonalcoholic families using latent growth modeling. The sample consisted of 226 families assessed at 18, 24, 36, and 48 months of child age. Results indicated that children in families with nonalcoholic parents had the lowest levels of aggressive behavior at all time points compared to children with one or more alcoholic parents. Children in families with two alcoholic parents did not exhibit normative decreases in aggressive behavior from 3 to 4 years of age compared to nonalcoholic families. However, this association was no longer significant once a cumulative family risk score was added to the model. Children in families with high cumulative risk scores, reflective of high parental depression, antisocial behavior, negative affect during play, difficult child temperament, marital conflict, fathers' education, and hours spent in child care, had higher levels of aggression at 18 months than children in low risk families. These associations were moderated by child gender. Boys had higher levels of aggressive behavior at all ages than girls, regardless of group status. Cumulative risk was predictive of higher levels of initial aggressive behavior in both girls and boys. However, boys with two alcoholic parents had significantly less of a decline in aggression from 36 to 48 months compared to boys in the nonalcoholic group.

Although there is evidence that environmental consequences for displaying tics and internalizing symptoms are related to tic severity in children with TS, less is known about the inter-relationships of these variables or how these factors jointly contribute to tic severity. This study included 45 children with Tourette syndrome. Caregivers reported on children's environmental consequences for displaying tics, internalizing symptoms, and tic severity. Results indicated that children with higher levels of internalizing symptoms experienced significantly more environmental consequences for displaying tics. Children with higher levels of separation anxiety symptoms demonstrated significantly greater tic severity. Environmental consequences for displaying tics accounted for significantly more variance in predicting tic severity than anxiety symptoms. This preliminary evidence suggests that environmental consequences for displaying tics, such as receiving accommodations or attention from others, have a greater influence on children's tic severity than emotional factors.

Parents' emotion coaching of children and modeling of effective emotional responses are associated with children's positive emotional development. However, much of the research in this area has been with European American families. This study examined parents' self-reports about their emotion regulation patterns and coaching their children about emotions, across three racial and ethnic groups (African American, European American, and Multiracial), to determine how well these parental behaviors predicted their children's self-reports of depressive and anxiety symptoms 18 to 24 months later (N = 99). For the African American families, a higher level of coaching about anger and sadness by mothers was linked with lower depressive symptoms in their children. A higher level of anger coaching by fathers within the Multiracial group was also associated with lower anxiety and depressive symptoms. This study supports the importance of cultural values, within racial and ethnic groups, in parenting approaches associated with children's mental health outcomes.

The aim was to validate self-perceived oral health with salivary IgG as an inflammatory parameter in children with type 1 diabetes. Unstimulated whole saliva samples were collected from 36 children with well controlled and 12 with poorly controlled type 1 diabetes and 40 non-diabetic children (Controls). Salivary flow rate, random blood glucose level, salivary protein concentration and immunoglobulin A and G levels were recorded using standard techniques. Data concerning oral health and diabetes status were collected. Self-perceived gingival bleeding (bleeding gums), bad breath and dry mouth were higher in diabetic children when compared with those in controls (P < 0.05). Gingival bleeding was frequently perceived by children with poorly controlled compared to well-controlled type 1 diabetes (P < 0.05) and controls (P < 0.001). Bad breath was common perceived by children with poorly controlled compared to well-controlled type 1 diabetes (P < 0.05) and controls (P < 0.0001). Salivary flow rate was lower in the diabetic children compared to controls (P < 0.01) with no difference between children with poorly controlled and well-controlled type 1 diabetes. Salivary IgG per mg protein concentration was higher in the diabetics when compared with the control group (P < 0.0001). IgG per mg protein levels were also higher in children with poorly controlled when compared with well-controlled type 1 diabetes (P < 0.05). There was no difference in IgA per mg protein and total protein concentrations between children with poorly controlled and well-controlled type 1 diabetes. Self-perceived gingival bleeding and salivary IgG per mg protein concentration were increased in children with type 1 diabetes compared with controls. These variables were also increased in children with poorly controlled compared with well-controlled type 1 diabetes.

We examined findings from five organophosphorus pesticide biomonitoring studies conducted in Washington State between 1994 and 1999. We compared urinary dimethylthiophosphate (DMTP) concentrations for all study groups and composite dimethyl alkylphosphate (DMAP) concentrations for selected groups. Children of pesticide applicators had substantially higher metabolite levels than did Seattle children and farmworker children (median DMTP, 25 μg/L; p < 0.0001). Metabolite levels of children living in agricultural communities were elevated during periods of crop spraying. Median DMTP concentrations for Seattle children and farmworker children did not differ significantly (6.1 and 5.8 μg/L DMTP, respectively; p = 0.73); however, the DMAP concentrations were higher for Seattle children than for farmworker children (117 and 87 nmol/L DMAP, respectively; p = 0.007). DMTP concentrations of U.S. children 6–11 years of age (1999–2000 National Health and Nutrition Examination Survey population) were higher than those of Seattle children and farmworker children at the 75th, 90th, and 95th percentiles. DMTP concentrations for workers actively engaged in apple thinning were 50 times higher than DMTP concentrations for farmworkers sampled outside of peak exposure periods. We conclude that workers who have direct contact with pesticides should continue to be the focus of public health interventions and that elevated child exposures in agricultural communities may occur during active crop-spraying periods and from living with a pesticide applicator. Timing of sample collection is critical for the proper interpretation of pesticide biomarkers excreted relatively soon after exposure. We surmise that differences in dietary exposure can explain the similar exposures observed among farmworker children, children living in the Seattle metropolitan area, and children sampled nationally.

Childhood obesity is a serious public health problem in Mexico. Adult gut microbiota composition has been linked to obesity, but few studies have addressed the role of gut microbiota in childhood obesity. The aim of this study is to compare gut microbiota composition in obese and normal-weight children and to associate gut microbiota profiles with amino acid serum levels and obesity-related metabolic traits. Microbial taxa relative abundance was determined by 16S rRNA sequencing in 67 normal-weight and 71 obese children aged 6-12 years. Serum amino acid levels were measured by mass spectrometry. Associations between microbiota composition, metabolic parameters and amino acid serum levels were tested. No significant differences in phyla abundances or Firmicutes/Bacteroidetes ratios were observed between normal-weight and obese children. However, Bacteroides eggerthii abundance was significantly higher in obese children and correlated positively with body fat percentage and negatively with insoluble fibre intake. Additionally, Bacteroides plebeius and unclassified Christensenellaceae abundances were significantly higher in normal-weight children. Abundance of both these species correlated negatively with phenylalanine serum levels, a metabolite also found to be associated with obesity in Mexican children. The study identified bacterial species associated with obesity, metabolic complications and amino acid serum levels in Mexican children. © 2017 World Obesity Federation.

The exposure to pesticides amongst school-aged children (6-11 years old) was assessed in this study. One hundred twenty-five volunteer children were selected from two public schools located in an agricultural and in an urban area of Valencia Region, Spain. Twenty pesticide metabolites were analyzed in children's urine as biomarkers of exposure to organophosphate (OP) insecticides, synthetic pyrethroid insecticides, and herbicides. These data were combined with a survey to evaluate the main predictors of pesticide exposure in the children's population. A total of 15 metabolites were present in the urine samples with detection frequencies (DF) ranging from 5% to 86%. The most frequently detected metabolites with DF>53%, were 3,5,6-trichloro-2-pyridinol (TCPy, metabolite of chlorpyrifos), diethyl phosphate (DEP, generic metabolite of OP insecticides), 2-isopropyl-4-methyl-6-hydroxypyrimidine (IMPY, metabolite of diazinon) and para-nitrophenol (PNP, metabolite of parathion and methyl parathion). The calculated geometric means ranged from 0.47 to 3.36 µg/g creatinine, with TCPy and IMPY showing the higher mean concentrations. Statistical significant differences were found between exposure subgroups (Mann-Whitney test, p<0.05) for TCPy, DEP, and IMPY. Children living in the agricultural area had significantly higher concentrations of DEP than those living in the urban area. In contrast, children aged 6-8 years from the urban area, showed statistically higher IMPY levels than those from agricultural area. Higher levels of TCPy were also found in children with high consumption of vegetables and higher levels of DEP in children whose parents did not have university degree studies. The multivariable regression analysis showed that age, vegetable consumption, and residential use of pesticides were predictors of exposure for TCPy, and IMPY; whereas location and vegetable consumption were factors associated with DEP concentrations. Creatinine concentrations were the most important predictors of urinary TCPy and PNP metabolites. Copyright © 2014 Elsevier Inc. All rights reserved.

Reactive oxygen species (ROS)-induced DNA damage occurs in heavy metal exposure, but the simultaneous effect on DNA repair is unknown. We investigated the influence of co-exposure of lead (Pb), cadmium (Cd), and mercury (Hg) on 8-hydroxydeoxyguanosine (8-OHdG) and human repair enzyme 8-oxoguanine DNA glycosylase (hOGG1) mRNA levels in exposed children to evaluate the imbalance of DNA damage and repair. Children within the age range of 3-6 years from a primitive electronic waste (e-waste) recycling town were chosen as participants to represent a heavy metal-exposed population. 8-OHdG in the children's urine was assessed for heavy metal-induced oxidative effects, and the hOGG1 mRNA level in their blood represented the DNA repair ability of the children. Among the children surveyed, 88.14% (104/118) had a blood Pb level >5 μg/dL, 22.03% (26/118) had a blood Cd level >1 μg/dL, and 62.11% (59/95) had a blood Hg level >10 μg/dL. Having an e-waste workshop near the house was a risk factor contributing to high blood Pb (r s  = 0.273, p < 0.01), while Cd and Hg exposure could have come from other contaminant sources. Preschool children of fathers who had a college or university education had significantly lower 8-OHdG levels (median 242.76 ng/g creatinine, range 154.62-407.79 ng/g creatinine) than did children of fathers who had less education (p = 0.035). However, we did not observe a significant difference in the mRNA expression levels of hOGG1 between the different variables. Compared with children having low lead exposure (quartile 1), the children with high Pb exposure (quartiles 2, 3, and 4) had significantly higher 8-OHdG levels (β Q2  = 0.362, 95% CI 0.111-0.542; β Q3  = 0.347, 95% CI 0.103-0.531; β Q4  = 0.314, 95% CI 0.087-0.557). Associations between blood Hg levels and 8-OHdG were less apparent. Compared with low levels of blood Hg (quartile 1), elevated blood Hg levels (quartile 2) were associated with higher 8-OHdG levels (β Q2  = 0.236, 95% CI 0.039-0.406). Compared with children having low lead exposure (quartile 1), the children with high Pb exposure (quartiles 2, 3, and 4) had significantly higher 8-OHdG levels.

The importance of serum basal tryptase (sBT) levels on patients with venom allergy is highlighted in recent adulthood studies. The aim of this study was to evaluate the sBT levels of venom-allergic children with varying severity of clinical reactions. We also aimed to document the association between sBT levels and severe systemic reactions (SR). Serum basal tryptase levels were estimated by UniCAP (Pharmacia & Upjohn, Uppsala, Sweden). Children who suffered from large local reaction (LLR) or SR after insect stings were included along with healthy control subjects without a history of any local or SR after insect stings. A total of 128 children (55 with SR, 18 with LLR, and 55 age and sex-matched control subjects) with a median age of 8.9 years (range 3.2-17.4) were enrolled. Severe SR was encountered in 24 (44%) patients with SRs. The median level of sBT in children with SRs (median, interquartile range) [4.2 μg/l (3.6-4.9)] was significantly higher than in children with LLRs [3.1 μg/l (2.5-4.0)] and healthy control subjects [2.9 μg/l (2.3-3.4)] (P < 0.001). Logistic regression analysis revealed sBT ≥ 4.8 μg/l as a significant risk factor for severe SR (5.7 [1.5-21.4]; P = 0.01) in children with venom allergy. Our results indicate that sBT levels are associated with a higher risk of severe SR in children with insect venom hypersensitivity. Determination of sBT levels may help clinicians to identify patients under risk of severe SRs and optimal and timely use of therapeutic interventions in children with venom allergy. © 2013 John Wiley & Sons A/S.

Children from families with lower socioeconomic status (SES) evidence greater physiological dysregulation and poorer health. Despite recognition of environmental contributors, little is known about the influence of neighborhood characteristics. The present study examined the moderating role of community-level risks and resources on the relation of family SES to children's daily cortisol output and physical health during the kindergarten year. In fall and spring of kindergarten, children's (N = 338) daily total cortisol was measured and parents and teachers rated children's global physical health. Parents reported family SES. Neighborhood characteristics were assessed using the Child Opportunity Index, a population-level tool that evaluates the quality of multiple domains of neighborhood attributes. In fall, children reared in lower SES family environments had higher cortisol when residing in lower quality (lower opportunity) neighborhoods (b = -.097, p < .001), but there was no relation between family SES and children's cortisol in more advantaged (higher opportunity) neighborhoods (b = -.023, p = .36). Lower family SES was prospectively associated with poorer physical health in spring (controlling for fall health) only among children living in lower opportunity neighborhoods (b = -.250, p = .018) and was unrelated to physical health among children residing in higher opportunity neighborhoods (b = .042, p = .70). Higher opportunity neighborhoods may protect against the negative consequences of low family SES on children's stress physiology and physical health. Public health interventions that bolster neighborhood opportunities may benefit young children reared in socioeconomically disadvantaged family environments.

Integrated community case management (iCCM) relies on community health workers (CHWs) managing children with malaria, pneumonia, diarrhoea, and referring children when management is not possible. This study sought to establish the cost per sick child referred to seek care from a higher-level health facility by a CHW and to estimate caregivers' willingness to pay (WTP) for referral. Caregivers of 203 randomly selected children referred to higher-level health facilities by CHWs were interviewed in four Midwestern Uganda districts. Questionnaires and document reviews were used to capture direct, indirect and opportunity costs incurred by caregivers, CHWs and health facilities managing referred children. WTP for referral was assessed through the 'bidding game' approach followed by an open-ended question on maximum WTP. Descriptive analysis was conducted for factors associated with referral completion and WTP using logistic and linear regression methods, respectively. The cost per case referred to higher-level health facilities was computed from a societal perspective. Reasons for referral included having fever with a negative malaria test (46.8%), danger signs (29.6%) and drug shortage (37.4%). Among the referred, less than half completed referral (45.8%). Referral completion was 2.8 times higher among children with danger signs (p = 0.004) relative to those without danger signs, and 0.27 times lower among children who received pre-referral treatment (p < 0.001). The average cost per case referred was US$ 4.89 and US$7.35 per case completing referral. For each unit cost per case referred, caregiver out of pocket expenditure contributed 33.7%, caregivers' and CHWs' opportunity costs contributed 29.2% and 5.1% respectively and health facility costs contributed 39.6%. The mean (SD) out of pocket expenditure was US$1.65 (3.25). The mean WTP for referral was US$8.25 (14.70) and was positively associated with having received pre-referral treatment, completing referral and increasing caregiver education level. The mean WTP for referral was higher than the average out of pocket expenditure. This, along with suboptimal referral completion, points to barriers in access to higher-level facilities as the primary cause of low referral. Community mobilisation for uptake of referral is necessary if the policy of referring children to the nearest health facility is to be effective.

Mom told me scary things about this animal: parents installing fear beliefs in their children via the verbal information pathway.

This study investigated whether fear beliefs can be installed in children after parents had received negatively tinted information about a novel stimulus. Parents of children aged 8-13 years (N = 88) were presented with negative, positive, or ambiguous information about an unknown animal and then given a number of open-ended vignettes describing confrontations with the animal with the instruction to tell their children what would happen in these situations. Results indicated that children's fear beliefs were influenced by the information that was provided to the parent. That is, parents who had received negative information provided more threatening narratives about the animal and hence installed higher levels of fear beliefs in their children than parents who had received positive information. In the case of ambiguous information, the transmission of fear was dependent on parents' trait anxiety levels. More precisely, high trait anxious parents told more negative stories about the unknown animal, which produced higher fear levels in children. 2009 Elsevier Ltd. All rights reserved.

To study serum levels of heart-type fatty acid-binding protein (h-FABP) in children with chronic heart failure (CHF), and the correlation between heart function and the level of h-FABP, with the aim of studying the significance of h-FABP in CHF. Thirty-six children with CHF, including 16 cases of endocardial fibroelastosis (EFE) and 20 cases of dilated cardiomyopathy (DCM) were enrolled in the study. Thirty healthy children sevred as the control group. Serum levels of h-FABP were determined using ELISA, and left ventricular ejection fraction (LVEF), cardiac index (CI) and fractional shortening of the left ventricle (LVSF) were measured by two-dimensional echocardiography in the CHF group. Mean levels of h-FABP in the CHF group were significantly higher than in the control group (21.7±4.3 ng/mL vs 6.2±1.7 ng/mL; P<0.01). The worse the heart function, the higher the h-FABP levels (P<0.01). Mean levels of h-FABP in both the EFE and DCM groups were significantly higher than in the control group (P<0.01). Serum h-FABP concentrations were negatively correlated with LVEF, CI and LVSF (r=-0.65, -0.64 and -0.71 respectively; P<0.01) in the CHF group. Serum h-FABP levels increase in children with CHF and are closely related to the severity of the condition. Serum h-FABP levels can be used as a biomarker for the diagnosis of heart failure and the evaluation of its severity.

Using a risk-resilience framework, this study examined how varying levels of exposure to a natural disaster (EF-4 tornado) and children's characteristics (sex; anxiety) influenced the behavioral and psychological adjustment of children who shared a common risk factor predisaster (elevated aggression) prior to exposure through 1-year postdisaster. Participants included 360 children in Grades 4-6 (65% male; 78% African American) and their parents from predominantly low-income households who were already participating in a longitudinal study of indicated prevention effects for externalizing outcomes when the tornado occurred in 2011. Fourth-grade children who were screened for overt aggressive behavior were recruited in 3 annual cohorts (120 per year, beginning in 2009). Parent-rated aggression and internalizing problems were assessed prior to the tornado (Wave 1), within a half-year after the tornado (Wave 2), and at a 1-year follow-up (Wave 3). Children and parents rated their exposure to aspects of tornado-related traumatic experiences at Wave 3. Children displayed less reduction on aggression and internalizing problems if the children had experienced distress after the tornado or fears for their life, in combination with their pre-tornado level of anxiety. Higher levels of children's and parents' exposure to the tornado interacted with children's lower baseline child anxiety to predict less reduction in aggression and internalizing problems 1 year after the tornado. Higher levels of disaster exposure negatively affected at-risk children's level of improvement in aggression and internalizing problems, when life threat (parent- and child-reported) and child-reported distress after the tornado were moderated by baseline anxiety.

To understand the current situations of saturnism and blood lead levels of children resided in village and circumjacent areas, and to know its relations with sex, age and other factors on children' s health as to providing some evidences for prevention and control. An epidemiological survey was conducted for finding out the pollution sources and for a better understanding of the surrounding environment. All 221 children under 14 years old, from the lead pollution villages and surrounding establishments were enrolled, and their blood lead levels were detected by graphite atomizer absorption spectrophotometer method. Symptoms of the saturnism were investigated through a standardized questionnaire. SPSS13.0 software was administrated for data analysis. High blood lead level identification rate was 66.06% (146/221), and saturnism rate 32.13% (71/221). The children's blood lead levels among group 1, group 2, group 3 in this village and jade factory were (161.20 +/- 32.94), (176.60 +/- 43.62), (258.00 +/-106.08) and (238.01 +/- 55.20) microg/L respectively and the significant differences were observed through Kruskal-Wallis test (chi2 = 51.84, df= 3, P<0. 01). The blood lead levels of children from group 3 in this village and the jade factory were higher than those of other two groups. No correlation was found between children's age and blood lead level (r = 0.10, P = 0.13). There was a significant difference in blood lead levels between boys and girls (t' = 3.83, P<0.01). With the children's blood lead levels rising, the occurrence rate of main saturnism symptoms was significantly increased. This survey suggested that the pollution source was a coarse lead smelter. The blood lead level should ke overwhelmingly increased among children who live nearby the higher level of lead blood, that living nearby the lead smeltery,might result in stautnism and negative effect on children's healthy.

Previous studies have shown that persons having high Streptococcus mutans levels in the saliva are "at risk" for dental caries. Most investigators agree, that if high levels of S. mutans were identified early in the life of at-risk children, dental decay could be reduced or eliminated through intervention. The purpose of this study is to show an association between S. mutans levels and caries prevalence in a sample of elementary school children. The study group consisted of 242 school children, ages 5-13 years. The subjects were divided into two age groups, 5-8 years and 9-13 years. Approximately 59 percent were African Americans. The sample of 242 children were equally females and males, 50 percent in each group. The Dentocult SM Test was used to make S. mutans determinations. The df-t index was used to determine the number of decayed and filled teeth of children ages 5-8 years; the DMF-T Index estimated the number of decayed, missing or filled teeth of children ages 9-13 years. Dental caries were found in 58 percent of the children (mean = 2.67, and range of 1-11). Approximately 47 percent of the children with caries had high S. mutans levels (100K-1M). Females had higher S. mutans levels than males in the 9-13 age group, p < .05. Analysis of Variance Test indicated that S. mutans levels for older females (ages 9-13) were significantly higher than those observed in males the same age (p < .01). This trend was not observed in younger children, ages 5-8 years. In addition, no significant difference or interaction was noted by sex for S. mutans levels and decayed or filled teeth (df-t) for younger children. We conclude that high levels of Streptococcus mutans are related to increased number of decayed teeth and conversely, low Streptococcus mutans levels are related to fewer dental caries. This study was supported in part by Colgate-Palmolive Company and the National Dental Association Foundation, Inc.

OBJECTIVES: To determine the blood lead levels in children and to identify risk factors for elevated levels. DESIGN: Cross-sectional study. SETTING: Vancouver. PARTICIPANTS: Random sample of children aged 24 to 36 months, born and still resident in Vancouver. The sample was stratified proportionally by the median annual family income in the census tract where each family resided. OUTCOME MEASURES: Blood lead levels and risk factors for elevated blood lead levels, determined from a questionnaire administered to parents. RESULTS: Of the children in the sample, 42% (178/422) were ineligible or could not be located. Of the remaining children, 73% (177/244) participated and adequate blood specimens were obtained from 172. The mean blood lead level was 0.29 mumol/L (standard deviation 0.13 mumol/L). (A blood lead level of 1 mumol/L is equivalent to 20.7 micrograms/dL.) The lowest level was 0.06 mumol/L, and the highest was 0.85 mumol/L. Of children with adequate samples, 8.1% (14/172) had blood lead levels of 0.48 mumol/L or higher, and 0.6% (1/172) had a level higher than 0.72 mumol/L. The logarithms of the levels were normally distributed, with a geometric mean (GM) of 0.26 mumol/L (geometric standard deviation 1.56). Of approximately 70 possible predictors of blood lead levels analysed, those that showed a statistically significant association (p < 0.05) with increased blood lead levels were soldering performed in the home as part of an electronics hobby (GM blood lead level 0.34 mumol/L, 95% confidence interval [CI] 0.27 to 0.39 mumol/L), aboriginal heritage (GM blood lead level 0.33 mumol/L, 95% CI 0.28 to 0.39 mumol/L), dwelling built before 1921 (GM blood lead level 0.32 mumol/L, 95% CI 0.28 to 0.37 mumol/L), age of water service connection to dwelling (predicted blood lead level 0.00087 mumol/L [95% CI 0.00005 to 0.00169 mumol/L] higher per year since service connection) and decreased stature (predicted blood lead level 0.018 mumol/L [95% CI 0.0353 to 0.0015 mumol/L] higher for every standard deviation below the age-specific mean height). CONCLUSIONS: This study found much lower blood lead levels in children than those found in previous Canadian studies. The authors believe that this result is not an artefact due to differences in population sampling or methods of collection of blood specimens. The study showed no clear risk factors for elevated blood lead levels: although a few factors had a statistically significant association with increased blood lead levels, the differences in levels were small and unimportant.

Self-perceived overweight and weight discrimination are associated with inflammation in adulthood. We test whether there is an intergenerational association of parent perception of child overweight on higher levels of child c-reactive protein (CRP), a marker of inflammation implicated in stress. Data were from the National Health and Nutrition Examination Survey 2005-2014 (N=4988). Parents reported their perception of their child's weight; CRP was assayed from children's blood samples. Children whose parents perceived them as overweight had higher CRP levels than children who were perceived about the right weight; perceived underweight was also associated with higher CRP (F(2,4977)=9.23, p<.001). These associations were independent of the child's objective weight status and waist circumference and held when the sample was limited to children with objective overweight and obesity. These results suggest an intergenerational transfer of the psychological perception of body weight from parents to the inflammatory health of their child. Copyright © 2017 Elsevier B.V.

Urban children remain disproportionately at risk of having higher blood lead levels than their suburban counterparts. The Westside Cooperative Organization (WESCO), located in Marion County, Indianapolis, Indiana, has a history of children with high blood lead levels as well as high soil lead (Pb) values. This study aims at determining the spatial relationship between soil Pb sources and children's blood lead levels. Soils have been identified as a source of chronic Pb exposure to children, but the spatial scale of the source-recipient relationship is not well characterized. Neighborhood-wide analysis of soil Pb distribution along with a furnace filter technique for sampling interior Pb accumulation for selected homes (n = 7) in the WESCO community was performed. Blood lead levels for children aged 0-5 years during the period 1999-2008 were collected. The study population's mean blood lead levels were higher than national averages across all ages, race, and gender. Non-Hispanic blacks and those individuals in the Wishard advantage program had the highest proportion of elevated blood lead levels. The results show that while there is not a direct relationship between soil Pb and children's blood lead levels at a spatial scale of ~100 m, resuspension of locally sourced soil is occurring based on the interior Pb accumulation. County-wide, the largest predictor of elevated blood lead levels is the location within the urban core. Variation in soil Pb and blood lead levels on the community level is high and not predicted by housing stock age or income. Race is a strong predictor for blood lead levels in the WESCO community.

This study investigated the possible correlation between the degree of hearing impairment caused by neonatal purulent meningitis and the levels of CD64 and PCT in cerebrospinal fluid of patients, and assessed the prognostic value of such levels. We recorded data from 156 cases of neonatal purulent meningitis retrospectively. All the patients received brainstem response audiometry, and cerebrospinal fluid samples were collected within the first day after admission through lumbar puncture. Flow cytometry was used to detect CD64 levels and enzyme-linked fluorescent assay was used to detect PCT levels. The children with hearing impairment were followed up for 1 year and brainstem response audiometry was performed again in them. We found that 43.59% of the children showed different degrees of hearing impairment, and 55% of them did not fully recover. The levels of PCT and CD64 in cerebrospinal fluid of children with hearing impairment were significantly higher than those of children with normal hearing (P<0.01). The levels of PCT and CD64 in mild, moderate and severe hearing impaired children increased gradually with higher degrees of impairment, and the differences between groups were significant (P<0.01). During the follow-up, it was found that the levels of PCT and CD64 in children correlated well with the degree of hearing recovery, and the differences between groups were significant (P<0.01). In our study, approximately 1/4 children with purulent meningitis showed long-term hearing impairment. Based on our analyses, the levels of CD64 and PCT in cerebrospinal fluid can be used to predict the degree and long-term prognosis of hearing impairment caused by purulent meningitis in children.

Active commuting to school is associated to higher levels of physical activity among children. Family factors may influence on this behaviour. The objective was to analyze the association between parents' occupational activity and parents' mode of commuting to work with the mode of commuting of their children. A total of 721 families from 4 primary schools in the province of Granada participated in this study. Families reported a questionnaire about mode of commuting of their children, parents' occupational activity and mode of commuting to work, distance and travel time to school. Associations between family's occupational activity and mode of commuting to work with mode of commuting to school of their children were examined using binary logistic regression analysis adjusting for age and children's distance to school. Children whose parents did not work used to engage in higher levels of active commuting to school than those whose parents worked (p = 0,023; OR: 2,67; 95% CI: 1,14-6,23). Children whose parents used to commute actively to work used to engage in higher levels of active commuting to school than those whose parents both used passive modes of commuting to work (p = 0,014; OR: 6,30; 95% CI: 1,45-27,26). Family factors are related to mode of commuting to school in children: Unemployed families and employed families where parent are active commuters to work are more used to have children that commuted to school using active modes.

To study dyslipidemia types in children with metabolic syndrome. From 1520 children of total population 155 children aged from 9 to 18 years were selected, who formed 2 groups: 1 group--85 children with metabolic syndrome, 2 group--54 children with normal body mass. Anthropometry, blood pressure measurement, estimation of total cholesterol, low density cholesterol, very low density cholesterol, high density cholesterol, tryglicerides in blood were done. The total cholesterol level was 1,1 times higher (p = 0.001), low density cholesterol 1,4 times higher (p = 0.001), very low density cholesterol 1,1 times higher (p= 0.015), tryglicerides 1,1 times higher (p = 0.020) in children with metabolic syndrome than in children of control group. In children with metabolic syndrome sensitively more often IIa, IV dislipidemia types and isolated hypercholesterolemia and less often IIb, III dislipidemia types and high density cholesterol isolated decrease were diagnosed. So children with metabolic syndrome were characterized by atherogenic types of dislipidemias which determine early atherosclerosis development. Children with metabolic syndrome must be examined on the lipid metabolism violation with the aim of its prevention and correction.

The authors examined the role of food insecurity in the etiology of children's cognitive and mental health problems. Data from a prospective longitudinal study of 1,116 United Kingdom families with twins (sample constructed in 1999-2000) were used to test associations among household food insecurity; income; maternal personality; household sensitivity to children's needs; and children's cognitive, behavioral, and emotional development. Food-insecure children had lower IQs and higher levels of behavioral and emotional problems relative to their peers. After differences in household income, the personalities of children's mothers, and the sensitivity of household organization to children's needs were accounted for, food-insecure children had moderately higher levels of emotional problems relative to food-secure children (β = 0.22, P = 0.02). Differences in children's cognitive development were accounted for by household income, and differences in their behavioral development were accounted for by their mothers' personalities and their households' sensitivity to children's needs. Results suggest that food insecurity was associated with school-aged children's emotional problems but not with their cognitive or behavioral problems after accounting for differences in the home environments in which children were reared. Mothers' personality and household sensitivity to children's needs may present challenges to improving outcomes of children with food insecurity.

Obesity is accompanied by the formation of oxygen free radicals, whose intensified activity without effective defense mechanisms can lead to oxidative stress and related complications. We evaluated the presence of oxidative stress in obese prepubertal children. The study included 83 healthy children aged 2-10 years (62 with obesity and 21 nonobese controls). Total oxidant capacity (TOC), total antioxidant capacity (TAC), oxidized low-density lipoprotein (ox-LDL), lipid parameters, glucose, and C-reactive protein (CRP) were measured in serum. Oxidative stress index (OSI) was calculated. Serum TOC concentration was significantly higher ( p < 0.05) and TAC concentration was lower ( p < 0.05) in obese children. OSI was higher ( p < 0.01) in obese subjects compared with controls. CRP levels were normal in all children, but median CRP value was higher ( p < 0.01) and HDL cholesterol levels were lower ( p < 0.05) in the obese group. We found a significant negative correlation between TAC and ox-LDL concentrations ( r = -0.27, p < 0.05) in obese children. Furthermore, obesity duration was positively correlated with TOC level ( r = 0.32, p < 0.05) in this group. Obesity-related oxidative stress already occurs in prepubescence. Early obesity diagnosis and the necessary therapeutic activity implementation is a vital strategy for the prophylaxis of free radical damage and related multiorgan complications.

There are no good biomarkers to predict renal parenchymal involvement in children with urinary tract infection (UTI). Children (N = 73) younger than 5 years with UTI were enrolled. Urinary levels of 8-hydroxy-2'-deoxyguanosine (8-oxodG) and total antioxidant capacity (TAC) were checked as markers of oxidative stress and antioxidant capacity, respectively. Tc99m-dimercaptosuccinic acid (DMSA) renal scintigraphy was used to find evidence of renal involvement. Patients with positive DMSA findings had higher levels of urinary 8-oxodG (p = 0.003) and higher urinary TAC (p = 0.001) than patients with normal DMSA findings. High level of urinary 8-oxodG may be a risk factor of severe renal damage.

To examine whether the number and type of electronic screens available in children's bedrooms matter in their relationship to adiposity, physical activity and sleep. A cross-sectional study was conducted involving 502 children aged 9-11 years from Ottawa, Ontario. The presence (yes/no) of a television (TV), computer or video game system in the child's bedroom was reported by the parents. Percentage body fat was measured using bioelectrical impedance. An accelerometer was worn over seven days to assess moderate-to-vigorous physical activity (MVPA), total sedentary time, sleep duration and sleep efficiency. Screen time was self-reported by the child. After adjustment for age, sex, ethnicity, annual household income and highest level of parental education, children with 2-3 screens in their bedroom had a significantly higher percentage of body fat than children with no screen in their bedroom. However, while children with 2-3 screens in their bedroom engaged in more screen time overall than those with no screen, total sedentary time and MVPA were not significantly different. Sleep duration was not related to the number of screens in the bedroom, but sleep efficiency was significantly lower in children with at least 2 screens in the bedroom. Finally, children having only a TV in their bedroom had significantly higher adiposity than those having no screen at all. In contrast, the presence of a computer in children's bedrooms was not associated with higher adiposity than that of children with no screen. A higher number of screens in a child's bedroom was associated with higher adiposity, more total screen time and lower sleep efficiency. Having a TV in the bedroom appears to be the type of screen presence associated with higher levels of adiposity. Given the popularity of screens among children, these findings are increasingly relevant to health promotion strategies.

Exposure to benzene in air is a concern in Thailand, particularly since it was observed that the incidence of blood-related cancers, such as leukemia and lymphoma, has increased in the past few decades. In Bangkok, the mean atmospheric levels of benzene on main roads and in schools were 33.71 and 8.25 ppb, respectively, while in gasoline service stations and petrochemical factories the mean ambient levels were 64.78 and 66.24 ppb, respectively. Cloth vendors (22.61 ppb) and grilled-meat vendors (28.19 ppb) working on the roadsides were exposed to significantly higher levels of benzene than the control group (12.95 ppb; p<0.05). Bangkok school children (5.50 ppb) were exposed to significantly higher levels of benzene than provincial school children (2.54 ppb; p<0.01). Factory workers (73.55 ppb) and gasoline service attendants (121.67 ppb) were exposed to significantly higher levels of benzene than control workers (4.77 ppb; p<0.001). In accordance with the increased benzene exposures, levels of urinary trans,trans-muconic acid (MA) were significantly increased in all benzene-exposed groups. In school children, the levels of MA were relatively high, taking into account the much lower level of exposure. Blood benzene levels were also significantly increased in Bangkok school children (77.97 ppt; p<0.01), gasoline service attendants (641.84 ppt; p<0.05) and factory workers (572.61 ppt; p<0.001), when compared with the respective controls. DNA damage, determined as DNA strand breaks, was found to be elevated in gasoline service attendants, petrochemical factory workers, and Bangkok school children (p<0.001). The cytogenetic challenge assay, which measures DNA repair capacity, showed varying levels of significant increases in the numbers of dicentrics and deletions in gasoline service attendants, petrochemical factory workers and Bangkok school children, indicating a decrease in DNA repair capacity in these subjects.

During the summer of 1994, a cross-sectional epidemiological study, in which the pulmonary function of children in Tehran was compared with pulmonary function in children in a rural town in Iran, was conducted. Four hundred children aged 5-11 y were studied. Daytime ambient nitrogen dioxide, sulfur dioxide, and particulate matter were measured with portable devices, which were placed in the children's neighborhoods on the days of study. Levels of these ambient substances were markedly higher in urban Tehran than in rural areas. Children's parents were questioned about home environmental exposures (including heating source and environmental tobacco smoke) and the children's respiratory symptoms. Pulmonary function was assessed, both by spirometry and peak expiratory flow meter. Forced expiratory volume in 1 s and forced vital capacity-as a percentage of predicted for age, sex and height-were significantly lower in urban children than in rural children. Both measurements evidenced significant reverse correlations with levels of sulfur dioxide, nitrogen dioxide, and particulate matter. Differences in spirometric lung function were not explained by nutritional status, as assessed by height and weight for age, or by home environmental exposures. Reported airway symptoms (i.e., cough, phlegm, and wheeze) were higher among rural children, whereas reported physician diagnosis of bronchitis and asthma were higher among urban children. The association between higher pollutant concentrations and reduced pulmonary function in this urban-rural comparison suggests that there is an effect of urban air pollution on short-term lung function and/or lung growth and development during the preadolescent years.

High level of caries activity is related to organisms in the dental plaque with high acidogenesis capacity. To test salivary pH in children of the same family and compare it with their caries status. To compare pH levels between children and their parents. To examine the relationship between pH and caries status among children of the same family and their parents. We examined 123 children and adolescents aged 3-18, (73 boys and 50 girls) and 33 adults, (12 men and 21 women), parents of these children. Caries status was examined clinically, using DMF index. Salivary pH measurements were made by a digital pH meter. Among adults, increase in patient age led to increased DMF (p = 0.005). The higher the pH, the lower the DMF (p = 0.037). Among men, DMF was lower by 3 compared to women (p = 0.049). Children's pH correlated with the parents' (p = 0.004). Children's DMF correlated to their pH (p = 0.001). Children's pH was the best predictor of their DMF (R2 = 0.309, p = 0.001). Among children, the higher the pH, the lower the DMFT. Children's pH was the best predictor of their DMF.

This study was conducted to measure the activity of the enzyme glutathione S-transferase (GST) in saliva and to compare the activity of this enzyme in children with and without dental fluorosis in communities with different concentrations of naturally fluoridated water. A total of 141 schoolchildren participated in this cross-sectional study. Children were selected from two communities: one with a low (0.4 ppm) and the other with a high (1.8 ppm) water fluoride concentration. Dental fluorosis was evaluated by applying the Thylstrup and Fejerskov Index (TFI) criteria. Stimulated saliva was obtained, and fluoride concentration and GST activity were measured. The GST activity was compared among children with different levels of dental fluorosis using multinomial logistic regression models and odds ratios (OR). The mean age of the children was 10.6 (±1.03) years. Approximately half of the children showed dental fluorosis (52.5 %). The average GST activity was 0.5678 (±0.1959) nmol/min/μg. A higher concentration of fluoride in the saliva was detected in children with a higher GST activity (p = 0.039). A multinomial logistic regression model used to evaluate the GST activity and the dental fluorosis score identified a strong association between TFI = 2-3 (OR = 15.44, p = 0.007) and TFI ≥ 4 (OR = 55.40, p = 0.026) and the GST activity level, compared with children showing TFI = 0-1, adjusted for age and sex. Schoolchildren with higher levels of dental fluorosis and a higher fluoride concentration in the saliva showed greater GST activity. The increased GST activity most likely was the result of the body's need to inactivate free radicals produced by exposure to fluoride.

This longitudinal study aimed to examine the enduring effects of parental HIV/AIDS on children's psychological well-being in Asia. A sample of 1625 children aged from 6 to 18 years old were assessed annually for their depressive symptoms over three years. Latent growth curve modeling (LGCM) was used to examine the trajectories of depressive symptoms among AIDS orphans and vulnerable children in comparison with children from HIV-free families. AIDS orphans demonstrated the highest initial level of depressive symptoms among the three groups. On average, children's depressive symptoms scores can be expected to realize an approximate 25% decrease for AIDS orphans, 19% decrease for vulnerable children and 15% decrease for comparison children over a 3-year period. Individual differences within the groups showed that children with higher initial level of depressive symptoms can be expected to decrease slower over time. Multiple group LGCM showed that the three groups of children demonstrated significantly different trajectories of depressive symptoms. Among the key demographic factors, only age exerted an effect on the trajectory of depressive symptoms of vulnerable children, indicating that the younger children showed higher level of initial depressive symptoms and lower rate of decrease than the older children. The current study enriched our knowledge on the longitudinal effect of parental HIV/AIDS on children's emotional distress. Future psychological support might take the children's developmental stages and cultural appropriateness into consideration and deliver service for the most vulnerable group of children affected by HIV/AIDS.

In a sample of 159 primary school children, the relationship between perceived parental rearing behaviours and self-reported attachment style, on the one hand, and worry, on the other hand, was investigated. Children completed (a) the EMBU, a questionnaire measuring perceptions of parental rearing behaviours, (b) a single-item measure of attachment style, and (c) the Penn State Worry Questionnaire for Children (PSWQ-C), an index of severity of worrying. Results showed that parental rearing behaviours, in particular rejection and anxious rearing, were positively associated with worry. Thus, children who perceived their parents as more rejective and anxious reported higher levels of worry. Furthermore, self-reported attachment style appeared to be related to worry. More specifically, children who classified themselves as avoidantly or ambivalently attached displayed higher levels of worry than did children who classified themselves as securely attached. These findings are consistent with the notion that family environment factors such as parental rearing and attachment style contribute to the severity of anxiety symptoms in children.

To determine the association, if any, between thyroid-stimulating hormone (TSH) levels and body mass index (BMI) percentiles in children with primary hypothyroidism who are chemically euthyroid and on treatment with levothyroxine. This retrospective cross-sectional study consisted of a review of medical records from RUSH Medical Center and Stroger Hospital, Chicago, USA of children with primary hypothyroidism who were seen in the clinic from 2008 to 2014 and who were chemically euthyroid and on treatment with levothyroxine for at least 6 months. The patients were divided into two groups based on their TSH levels (0.34-<2.5 mIU/L and ≥2.5-5.6 mIU/L). The data were analyzed by Spearman rank correlation, linear regression, cross tabulation and chi-square, Mann-Whitney U test, and Kruskal-Wallis test. One hundred and forty-six children were included, of which 26% were obese (BMI ≥95%), 21.9% overweight (BMI ≥85-<95%), and 52.1% of a healthy weight (BMI ≥5-<85%). There was a significant positive correlation between TSH and BMI percentiles (r=0.274, p=0.001) and a significant negative correlation between TSH and serum free T4 (r=-0.259, p=0.002). In the lower TSH group, 68.4% of the children had a healthy weight, while the percentage of obese children was 60.5% in the upper TSH group (p=0.012). In children diagnosed with primary hypothyroidism who are chemically euthyroid on treatment with levothyroxine, there is a positive association between higher TSH levels and higher BMI percentiles. However, it is difficult to establish if the higher TSH levels are a direct cause or a consequence of the obesity. Further studies are needed to establish causation beyond significant association.

The role of zinc in the nutrition and growth of children with chronic liver disease is poorly defined. The present study determined the serum zinc levels of children with compensated liver disease (CLD) and decompensated liver disease (DLD) and compared this with healthy children. Zinc levels were also correlated with the severity of liver disease as measured by Child-Pugh scores. The study comprised of 60 children 0-10 years of age with chronic liver disease, defined as CLD (n = 30) if the Child-Pugh score was < 6, and DLD (n = 30) if the Child-Pugh score was > or = 6. Thirty healthy children 0-10 years served as controls. Serum zinc levels were measured by atomic absorption spectrometry. The 90 patients included 30 with CLD (mean age: 4.54 years: 21 boys; mean Child-Pugh score: 5.83), 30 with DLD (mean age: 1.39 years; 17 boys; mean Child-Pugh score: 9.53) and 30 healthy children (mean age: 4.6; 16 boys). Zinc levels of patients with CLD were significantly lower compared with the healthy controls (Mean [standard deviation]: 68.07 [31.55]vs 89.9 [25.9]microg/dL, P = 0.000), but significantly higher compared to the patients with DLD (48.8 [26.8]microg/dL). Correlation studies showed that the higher the Child-Pugh score, the lower the zinc levels (r = -0.460) Children with chronic liver disease, whether in a compensated or decompensated state, had lower serum zinc levels compared with the healthy controls. As the severity of liver disease worsened, the zinc levels decreased. The study suggests that zinc supplementation should constitute part of the micronutrient intake of children with chronic liver disease.

Children's soft toys are known to harbour house dust mite (HDM) allergens, but little is known whether they harbour cat or dog allergens. The objective of the study was to measure cat (Fel d 1), dog (Can f 1) and HDM allergens on children's soft toys. Dust was collected from 40 children's soft toys and their mattresses. Data were collected on pet ownership. Dust samples were analysed for Fel d 1, Can f 1, Der p 1 and Der f 1 by enzyme-linked immunosorbent assay (ELISA) and results are expressed as median levels with inter-quartile ranges. Thirty-five (87.5%) soft toys had detectable Fel d 1 levels (median: 0.73 µg/g; inter-quartile range: 0.26-2.56 µg/g) while 34 (85%) had detectable Can f 1 levels (1.20 µg/g; 0.53-2.68). Correspondingly, 32 (80%) mattresses had detectable Fel d 1 levels (0.18 µg/g, 0.07-1.01) while 34 (85%) had detectable Can f 1 levels (0.50 µg/g; 0.33-1.06). All mattresses and soft toys had detectable HDM allergen (Der p 1 + Der f 1) levels with soft toys containing about three times higher levels than mattresses. In homes with cats (n = 10) Fel d 1 levels were higher on soft toys than homes without cats (2.49 versus 0.48 µg/g; p = 0.0009). In homes with dogs (n = 25) Can f 1 levels were generally higher on soft toys (1.38 versus 0.63 µg/g; p = 0.10). This study has shown that soft toys can harbour cat and dog allergen as well as HDM allergens, some with very high levels. Cat and dog ownership resulted in higher Fel d 1 and Can f 1 levels on soft toys and mattresses. The levels of Fel d 1, Can f 1 and HDM allergens on soft toys could be of importance to sensitized asthmatic children.

Perfectionism and Anxiety: A Paradox in Intellectual Giftedness?

Guignard, Jacques-Henri; Jacquet, Anne-Yvonne; Lubart, Todd I.

Numerous authors reported a prevalence of perfectionism in gifted populations. In addition, an unhealthy form of perfectionism that leads to anxiety disorder has been described. Using self-report measures (CAPS and R-CMAS) with 132 children, we hypothesized that intellectually gifted children express a higher level of perfectionism and anxiety. Our results pointed out a paradox: the gifted group obtained a higher self-oriented perfectionism score than the control group in 6th grade, but present the same level of anxiety. In contrast, the gifted group showed the same level of perfectionism than non-gifted 5th graders, but reported a higher anxiety level. Thus, the interplay between perfectionism and anxiety appears to be more complex than a simple linear relationship in giftedness. PMID:22859964

The aim of this study was to evaluate the DDT, DDE, and 1-hydroxypyrene exposure levels of children living in communities located in southeastern Mexico. The study communities were Lacanja and Victoria in Chiapas state and Ventanilla in Oaxaca state. Children living in Lacanja had total blood DDT levels (mean ± SD, 29,039.6 ± 11,261.4 ng/g lipid) that were significantly higher than those of children in Victoria (10,220.5 ± 7,893.1 ng/g lipid) and Ventanilla (11,659.7 ± 6,683.7 ng/g lipid). With respect to the 1-hydroxypyrene levels in urine samples, the levels in Lacanja (4.8 ± 4.1 μg/L or 4.5 ± 3.9 μmol/mol creatinine) and Victoria (4.6 ± 3.8 μg/L or 3.9 ± 3.0 μmol/mol Cr) were significantly higher than levels found in Ventanilla (3.6 ± 1.4 μg/L or 2.5 ± 0.5 μmol/mol Cr). In conclusion, our data indicate high levels of exposure in children living in the communities studied in this work. The evidence found in this study could be further used as a trigger to revisit local policies on environmental exposures.

To study the serum ferritin levels in children with acute leukemia, depending on the number of transfusions of RBC concentrate and period of disease. We studied the red blood count, serum iron and ferritin levels in 54 patients with acute leukemia before chemotherapy, at the time of a standardized treatment protocol, and after transfusions of RBC concentrates. In the debute of acute leukemia just before treatment lauch the serum ferritin in 81.5% of children was 2.3-2.5 higher than normal. The need for transfusion of RBC concentrates was higher under serum ferritin level exceeding 500 ng/mL. The association was established between ferritin content and age of the children, variant of acute leukemia and period of the disease. The level of serum ferritin can be used as a marker of ferrokinetic status for timely diagnosis of iron overload in children with acute leukemias and for application of treatment-and-prophylactic actions.

Neurodevelopmental treatment is an advanced therapeutic approach for the neural rehabilitation of children with cerebral palsy. Cerebral palsy represents a spectrum of neurological disorders primarily affecting gross motor function. The authors investigated the effects of neurodevelopmental treatment on serum levels of transforming growth factor-β1 (TGF-β1), a neuroprotective cytokine, and improvements to motor skills. Serum TGF-β1 levels and total score of the Gross Motor Function Measure-88 (GMFM-88) were significantly higher in children with cerebral palsy who underwent neurodevelopmental treatment compared to untreated patients (P < .01). Furthermore, the improved GMFM-88 total scores after neurodevelopmental treatment were significantly higher in children under the age of 3 with cerebral palsy than in older patients (P < .01). The authors demonstrate that the integration of TGF-β1 levels and GMFM-88 total score could be used to assess the efficacy of neurodevelopmental treatment. Moreover, the findings provide further scientific support for the early intervention and neurological rehabilitation of young children with cerebral palsy. © The Author(s) 2016.

The objective of this study is to determine children's blood lead levels and identify sources of lead exposure. Childhood lead exposure constitutes a major pediatric health problem today in China. A blood lead screening survey program for children in the age group of 2-12 years residing in Pearl River Delta region, south of China, was carried out from Dec 2007 to Jan 2008. Blood lead levels and lead isotope ratios of a total of 761 participants were assessed by inductively coupled plasma mass spectroscopy. Measurements of urban environmental samples for source identification of children lead exposure were also performed. The geometric mean value of the children's blood lead levels was 57.05 μg/L, and 9.6% of them were higher than 100 μg/L. The blood lead levels were still much higher than those in developed countries. Based on the data of environmental lead source inventories, lead isotopic tracing revealed that there is about 6.7% past used gasoline Pb embedded in Shenzhen residential dust and about 15.6% in Guangzhou dust, respectively.

Abstract Transplacental nucleoside analogue exposure can affect infant mitochondrial DNA (mtDNA). We evaluated mitochondria in peripheral blood mononuclear cells of children with and without clinical signs of mitochondrial dysfunction (MD) and antiretroviral (ARV) exposure. We previously identified 20 children with signs of MD (cases) among 1037 HIV-uninfected children born to HIV-infected women. We measured mtDNA copies/cell and oxidative phosphorylation (OXPHOS) NADH dehydrogenase (complex I) and cytochrome c oxidase (complex IV) protein levels and enzyme activities, determined mtDNA haplogroups and deletions in 18 of 20 cases with stored samples and in sex- and age-matched HIV-uninfected children, both ARV exposed and unexposed, (1) within 18 months of birth and (2) at the time of presentation of signs of MD. In specimens drawn within 18 months of birth, mtDNA levels were higher and OXPHOS protein levels and enzyme activities lower in cases than controls. In contrast, at the time of MD presentation, cases and ARV-exposed controls had lower mtDNA levels, 214 and 215 copies/cell, respectively, than ARV-unexposed controls, 254 copies/cell. OXPHOS protein levels and enzyme activities were lower in cases than exposed controls, and higher in cases than unexposed controls, except for complex IV activity, which was higher in cases. Haplotype H was less frequent among cases (6%) than controls (31%). No deletions were found. The long-term significance of these small but potentially important alterations should continue to be studied as these children enter adolescence and adulthood. PMID:21142587

Breastfeeding has been associated with improved neurodevelopment in children. However, it remains unknown to what extent nutritional advantages of breast milk may explain this relationship. We assessed the role of parental psychosocial factors and colostrum long-chain polyunsaturated fatty acid (LC-PUFA) levels in the relationship between breastfeeding and children's neurodevelopment. A population-based birth cohort was established in the city of Sabadell (Catalonia, Spain) as part of the INMA-INfancia y Medio Ambiente Project. A total of 657 women were recruited during the first trimester of pregnancy. Information about parental characteristics and breastfeeding was obtained by using a questionnaire, and trained psychologists assessed mental and psychomotor development by using the Bayley Scales of Infant Development in 504 children at 14 months of age. A high percentage of breastfeeds among all milk feeds accumulated during the first 14 months was positively related with child mental development (0.37 points per month of full breastfeeding [95% confidence interval: 0.06-0.67]). Maternal education, social class, and intelligence quotient only partly explained this association. Children with a longer duration of breastfeeding also exposed to higher ratios between n-3 and n-6 PUFAs in colostrum had significantly higher mental scores than children with low breastfeeding duration exposed to low levels. Greater levels of accumulated breastfeeding during the first year of life were related to higher mental development at 14 months, largely independently from a wide range of parental psychosocial factors. LC-PUFA levels seem to play a beneficial role in children's mental development when breastfeeding levels are high.

Background Autism is a pervasive neurodevelopmental disorder,thought to be caused by a combination of genetic heritability and environmental risk factors. Some autistic-like traits have been reported in mothers of autistic children. We hypothesized that dysregulation of oxytocin (OXT), Arg-vasopressin (AVP) and sex hormones, found in autistic children, may also exist in their mothers. Methods We determined plasma levels of OXT (40 in autism vs. 26 in control group), AVP (40 vs. 17) and sex hormones (61 vs. 47) in mothers of autistic and normal children by enzyme immunoassay and radioimmunoassay, respectively and investigated their relationships with the children’s autistic behavior scores (Childhood Autism Rating Scale (CARS) and Autism Behavior Checklist (ABC)). Results Significantly lower plasma concentrations of OXT (p<0.001) and AVP (p<0.001), as well as a higher level of plasma testosterone (p<0.05), were found in mothers of autistic children vs. those of control. The children’s autistic behavior scores were negatively associated with maternal plasma levels of OXT and AVP. Conclusions These results suggest that dysregulation of OXT, AVP and/or testosterone systems exist in mothers of autistic children, which may impact children’s susceptibility to autism.

Subjects undergoing chemotherapy often develop disorders in salivation and changes in salivary composition. Therefore, a tendency to inflammatory states developing within oral mucosa is often observed. The objective of the study was to assess the effect of disturbed immunity on the gum condition in children with acute lymphoblastic leukaemia (ALL) during anti-tumour treatment and to compare saliva interleukin-2 (IL-2) concentration in relation to the condition of gums oral mucositis-must be removed in children with ALL. The study included 78 children with ALL in followed three examinations and a control group included 78 healthy children. Dental examination of the children with ALL and the control group included the evaluation of gingival condition by gingival index (GI). Children's unstimulated saliva samples were taken, and IL-2 concentration was determined by Human IL-2 EIA. Mean GI higher than 1 was observed in 3.17 % children with ALL. The results found higher frequency of gingival inflammations in children with ALL on chemotherapy compared with the healthy controls. A comparison of results for a given patient during anti-tumour therapy with regard to salivary IL-2 showed significant differences between examination 2 and examination 3. The results indicated that IL-2 level in saliva was twice higher in a patient during chemotherapy. An increase in salivary level of the proinflammatory IL-2 cytokine in ALL children during chemotherapy may cause pathological changes in the condition of the gums. An increase in salivary IL-2 level most probably results from a micro-injury of oral mucosa following administration of cytostatics, which in turn may cause oral mucositis in children with ALL.

A growing number of studies indicate that low income, African American men and women living in urban environments are at high risk for trauma exposure, which may have intergenerational effects. The current study employed psychophysiological methods to describe biomarkers of anxiety in children of traumatized mothers. Study participants were recruited from a highly traumatized urban population, comprising mother-child pairs (n=36) that included school-age children. Mothers were assessed for childhood abuse with the Childhood Trauma Questionnaire, as well as symptoms of depression and posttraumatic stress disorder (PTSD). The children were measured for dark-enhanced startle responses and heart-rate variability. Dark-enhanced startle was found to be higher in children whose mothers had high levels of childhood physical abuse, as compared to children whose mothers had low levels of physical abuse. During the habituation phase of the startle experiment, children whose mothers had high levels of childhood emotional abuse had higher sympathetic system activation compared to children of mothers with low emotional abuse. These effects remained significant after accounting for maternal symptoms of PTSD and depression, as well as for the child's trauma exposure. These results demonstrate that children of mothers who have history of childhood physical and emotional abuse have higher dark-enhanced startle as well as greater sympathetic nervous system activation than children of mothers who do not report a history of childhood physical and emotional abuse, and emphasize the utility of physiological measures as pervasive biomarkers of psychopathology that can easily be measured in children. © 2011 The Authors.

The aim of this study was to compare the level of stress in mothers of school-aged children born late preterm and admitted to the intensive care unit (ICU) with the level of maternal stress if a child was born late preterm and not admitted to the ICU as well as if a full-term child was admitted to the ICU. In this retrospective cohort study the data were gathered via telephone interview with mothers. The Parenting Stress Index/Short Form was used to determine the level of stress in mothers. Background demographic characteristics, medically relevant variables, and the level of stress were tested using the chi-square test and Kruskal-Wallis test. Logistic regression was used in order to identify predictors of significant level of stress. Mothers of late preterm born children who were admitted to the ICU, as well as mothers of late preterm children who were not admitted had higher level of stress compared to mothers of full-term children. Namely, mothers of late preterm born children admitted to the ICU had 18-fold increase in risk for significant level of total stress (OR = 18.09; 95% CI 8.55 to 38.26) while 24-fold greater risk was observed in mothers of late preterm children who were not admitted to the ICU (OR = 24.05; 95% CI 10.66 to 54.26) in comparison to mothers of full-term born children. Results indicate that preterm birth and its complications are associated with a higher level of stress in mothers, that persists to school age. © 2016 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

Lead is a heavy metal known to be detrimental to neurologic, physiologic, and behavioral health of children. Previous studies from Jamaica reported that mean lead levels in soil are four times that of lead levels in some other parts of the world. Other studies detected lead levels in fruits and root vegetables, which were grown in areas with lead contaminated soil. In this study, we investigate environmental factors associated with blood lead concentrations in Jamaican children. The participants in this study comprised 125 typically developing (TD) children (ages 2–8 years) who served as controls in an age- and sex-matched case-control study that enrolled children from 2009 – 2012 in Jamaica. We administered a questionnaire to assess demographic and socioeconomic information as well as potential exposures to lead through food. Using General Linear Models (GLMs), we identified factors associated with blood lead concentrations in Jamaican children. The geometric mean blood lead concentration (GMBLC) in the sample of children in this study was 2.80 μg/dL. In univariable GLM analyses, GMBLC was higher for children whose parents did not have education beyond high school compared to those whose parents had attained this level (3.00 μg/dL vs. 2.31 μg/dL; P = 0.05), children living near a high traffic road compared to those who did not (3.43 μg/dL vs. 2.52 μg/dL; P < 0.01), and children who reported eating ackee compared to those who did not eat this fruit (2.89 μg/dL vs. 1.65 μg/dL; P < 0.05). In multivariable analysis, living near a high traffic road was identified as an independent risk factor for higher adjusted GMBLC (3.05 μg/dL vs. 2.19 μg/dL; P = 0.01). While our findings indicate that GMBLC in Jamaican children has dropped by at least 62% during the past two decades, children living in Jamaica still have GMBLC that is twice that of children in more developed countries. In addition, we have identified significant risk factors for higher blood lead concentrations in Jamaican children. We believe increasing awareness among parents regarding these risk factors could potentially lead to a lower level of lead exposure in Jamaican children. PMID:25837555

The nature and level of ego functioning were assessed in 41 recently detected physically abused children, and in two control groups of 38 neglected and 35 non-abused/non-neglected children (aged 6 to 12 years), using the Child Suicidal Potential Scales (CSPS). The results obtained in this study support the hypothesis that the influences of parental violence on the child's ego functions are detrimental, as reflected by significantly higher impairments in affect regulation (like irritability, anger, passivity, depression), low levels of impulse control, distortions in reality testing, and extensive operation of immature defense mechanisms in the physically abused children in comparison to the controls. Significant differences between the physically abused and the non-abused/non-neglected children were found for all mechanisms except displacement. The differences between the physically abused and neglected children for regression, denial and splitting, projection, and introjection (high scores for the physically abused children), and for compensation and undoing (higher scores for the neglected children) were also significant. It is suggested that physically abused children should be distinguished as a high-risk population for future personality disorders.

Data were collected by using the Child Introduction Form, Children's Depression Inventory, the Human Figure Drawing test, and children's drawings. The results showed that the depressive symptom levels of children with cancer were significantly higher than those of healthy children. Impulsivity, mistrust, and anger were observed significantly more in children with cancer (P < .05). Although anxiety was equal in the two groups, shyness was observed more in the cancer group, though the difference was not significant (P > .05). The emotional indicators of both groups of children did not have an effect on their depression scores.

To investigate the relationship between zonulin levels and clinical and laboratory parameters of childhood obesity. The study included obese children with a body mass index (BMI) >95 th percentile and healthy children who were of similar age and gender distribution. Clinical (BMI, waist circumferences, mid-arm circumference, triceps skinfold, percentage of body fat, systolic blood pressure, diastolic blood pressure) and biochemical (glucose, insulin, lipid levels, thyroid function tests, cortisol, zonulin and leptin levels) parameters were measured. A total of 43 obese subjects (23 males, mean age: 11.1±3.1 years) and 37 healthy subjects (18 males, mean age: 11.5±3.5 years) were included in this study. Obese children had significantly higher insulin, homeostasis model assessment of insulin resistance, triglyceride, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (HDL-C), zonulin and leptin levels than healthy children (p<0.05), while glucose levels were not different (p>0.05). Comparison of the obese children with and without insulin resistance showed no statistically significant differences for zonulin levels (p>0.05). Zonulin levels were found to negatively correlate with HDL-C and positively correlate with leptin levels, after adjusting for age and BMI. To the best of our knowledge, this is the first study investigating the relationship between circulating zonulin level (as a marker of intestinal permeability) and insulin resistance and leptin (as markers of metabolic disturbances associated with obesity) in childhood obesity. The results showed that zonulin was significantly higher in obese children when compared to healthy children, a finding indicating a potential role of zonulin in the etiopathogenesis of obesity and related disturbances.

This study examines the association between expectant parents' psychological distress and children's development at 36 months old. This is a prospective population study based on the Norwegian Mother and Child Cohort Study, N = 31,663. Logistic regression models were used to assess whether high scores (cutoff ≥ 2.00) on the symptom checklist-5 in parents predicted higher levels (cutoff ≥ 90 percentile) of developmental problems in their children. The risk of emotional and behavioral problems were significantly increased in children when both parents were affected by psychological distress during pregnancy, fully adjusted OR 2.35 (95% CI 1.36, 4.07) and OR 2.65 (96% CI 1.564.48), respectively. The risk was higher when mothers reported high level of psychological distress than when only the fathers did, but the risk of emotional difficulties in children was highest when both parents presented high levels of psychological distress, indicating an additive effect of parental psychological distress.

Background Indoor air quality has an effect on respiratory health. Children are more vulnerable to a decreased indoor air quality as their lungs are still developing. We measured levels of allergens and β-(1,3)-glucans in 19 school buildings and determined whether measured levels could be reproduced. School levels were compared to those in 169 homes and the effect of building characteristics on both home and school exposure was explored. Methods Electrostatic Dust fall Collectors were placed in school buildings for 8 weeks and in homes for 2 weeks to collect settled airborne dust. Cat, dog, and mouse allergen levels, domestic mite antigen levels and β-(1,3)-glucans were measured in the extracts from the collectors. Results were corrected for sampling duration. Using questionnaire data, relations between measured levels and building and classroom characteristics were explored. Results In schools, exposure levels were highest in classrooms and were influenced by the socioeconomic status of the children, the season measurements were performed, moisture status of the building and pet ownership. Repeated measurements in different seasons and over the years showed significantly different levels. Home exposure was influenced by socioeconomic status, occupancy and pet ownership. Domestic mite antigen was found in higher levels in extracts from homes compared to schools while pet allergen levels were 13 times higher in schools compared to homes without pets. For mouse allergen overall levels of exposure were low but still two times higher in schools compared to homes. Levels of β-(1,3)-glucans were also approximately two times higher in schools than in homes. Conclusion Exposure levels of several allergens and β-(1,3)-glucans in schools differ over time and are higher than in homes. For children, exposure levels measured at school could contribute to their total exposure as especially animal allergen levels can be much higher in schools compared to homes. PMID:24551183

To examine whether bullying is a risk factor for psychological distress among children in poor, urban South Africa. To determine risk and protective factors for bullying victimization. One thousand and fifty children were interviewed in deprived neighborhoods, including orphans, AIDS-affected children, streetchildren, and child-headed households. Using standardized scales, children reported on bullying victimization, psychological problems, and potential risk and protective factors at individual, peer, family, and community levels. 34% of children reported bullying victimization. Bullied children showed higher levels of anxiety, depression, suicidal ideation, and post-traumatic stress, as well as higher levels of clinical-level disorder. Risk factors for being bullied were being a victim of physical or sexual abuse or domestic violence at home, living in a high-violence community, and experiencing AIDS-related stigma (independent of sociodemographic cofactors and child psychological disorder). Protective factors were sibling support and support from friends, although findings suggest that friendship groups may also be sources of bullying for AIDS-affected children. Bullying is an independent and important risk factor in child psychological distress in South Africa. Children victimized at home or in the community are more likely to be bullied, suggesting a cycle of violence. Those working with children in Southern Africa should be alert to risk of bullying, especially among abused or AIDS-affected children. Interventions combating community violence and AIDS-related stigma may have additional positive impacts on bullying, and promotion of peer and sibling support may reduce bullying victimization among high-risk children.

Both small-for-gestational-age (SGA) and preterm birth have been associated with an increased incidence of adult cardiovascular disease and diabetes mellitus type 2. However, it is unclear whether preterm birth has an additional effect on cardiovascular risk factors in short children born SGA. Our objective was to investigate whether prematurity has an independent influence on several cardiovascular risk factors within a population of short SGA children. A cross-sectional observational study was performed. A total of 479 short SGA children (mean age 6.8 yr), divided into preterm (<36 wk) and term (> or =36 wk) children, was included in the study. Insulin sensitivity, beta-cell function, body composition, and lipid levels were studied in subgroups, and blood pressure (BP), anthropometry at birth and during childhood in the total group. Preterm SGA children were significantly lighter and shorter at birth after correction for gestational age than term SGA children (P < 0.001) but had a comparable head circumference. In preterm SGA children, we found a significantly higher systolic (P = 0.003) and diastolic BP sd score (P = 0.026), lower percent body fat sd score (P = 0.011), and higher insulin secretion (P = 0.033) and disposition index (P = 0.021), independently of the degree of SGA. Insulin sensitivity, serum lipid levels, muscle mass, and body fat distribution were comparable for preterm and term SGA children. Within a population of short SGA children, preterm birth has divergent effects on several cardiovascular risk factors. Whereas preterm SGA children had a higher systolic and diastolic BP, they also had a lower percent body fat and a higher insulin secretion and disposition index than term SGA children.

Moraxella catarrhalis (Mcat) is a prominent mucosal pathogen causing acute otitis media (AOM). We studied Mcat nasopharyngeal (NP) colonization, AOM frequency and mucosal antibody responses to four vaccine candidate Mcat proteins: outer membrane protein (OMP) CD, oligopeptide permease (Opp) A, hemagglutinin (Hag), and Pilin A clade 2 (PilA2) from stringently defined otitis prone (sOP) children, who experience the greatest burden of disease, compared to non-otitis prone (NOP) children. sOP children had higher NP colonization of Mcat (30 vs. 22%, P = 0.0003) and Mcat-caused AOM rates (49 vs. 24%, P < 0.0001) than NOP children. Natural acquisition of mucosal antibodies to Mcat proteins OMP CD (IgG, P < 0.0001), OppA (IgG, P = 0.018), Hag (IgG and IgA, both P < 0.0001), and PilA2 (IgA, P < 0.0001) was lower in sOP than NOP children. Higher levels of mucosal IgG to Hag (P = 0.039) and PilA2 (P = 0.0076), and IgA to OMP CD (P = 0.010), OppA (P = 0.030), and PilA2 (P = 0.043) were associated with lower carriage of Mcat in NOP but not sOP children. Higher levels of mucosal IgG to OMP CD (P = 0.0070) and Hag (P = 0.0003), and IgA to Hag (P = 0.0067) at asymptomatic colonization than those at onset of AOM were associated with significantly lower rate of Mcat NP colonization progressing to AOM in NOP compared to sOP children (3 vs. 26%, P < 0.0001). In conclusion, sOP children had a diminished mucosal antibody response to Mcat proteins, which was associated with higher frequencies of asymptomatic NP colonization and NP colonization progressing to Mcat-caused AOM. Enhancing Mcat antigen-specific mucosal immune responses to levels higher than achieved by natural exposure will be necessary to prevent AOM in sOP children. PMID:28848555

We investigated 1) the impact of differences in intelligence quotient discrepancy (IQD) on motor skills of preschool-aged children with autism spectrum disorders (ASD); 2) the relationships between IQD and motor skills in preschool-aged children with ASD. A total of 127 ASD preschool-aged children were divided into three groups according to the size of the IQD: IQD within 1 standard deviation (1SD; EVENIQ; n=81), discrepantly higher verbal intelligence quotient (VIQ; n=22; VIQ>performance intelligence quotient [PIQ] above 1SD [≥15 points]), and discrepantly higher PIQ (n=24; PIQ>VIQ above 1SD [≥15 points]). Children's IQD and motor skills were determined with the Wechsler Preschool and Primary Scale of Intelligence™ - Fourth Edition and the motor subtests of the Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT), respectively. One-way analysis of variance revealed significant group differences for the fine motor domain of the CDIIT and the visual-motor coordination subtest ( F =3.37-4.38, p <0.05). Children with discrepantly higher PIQ were associated with better fine motor skills than were children with even IQD and those with discrepantly higher VIQ, and vice versa. IQD (PIQ - VIQ) had significant positive correlations with the fine motor domain and fine motor subtests of the CDIIT ( r =0.18-0.29, p <0.05). The IQD can identify different levels of fine motor skills in preschool-aged children with ASD. This study suggests important implications for clinicians, therapists, and researchers: discrepantly higher PIQ could be related to better visual-motor coordination, and discrepantly higher VIQ could be related to poor visual-motor coordination. Furthermore, the results support that when therapists are working with preschool-aged children with ASD who are developing fine motor skills or undertaking fine motor tasks related to visual-motor coordination, they may need to pay attention to the children's IQD.

High-mobility group box-1 protein, lipopolysaccharide-binding protein, interleukin-6 and C-reactive protein in children with community acquired infections and bacteraemia: a prospective study

PubMed Central

2010-01-01

Introduction Even though sepsis is one of the common causes of children morbidity and mortality, specific inflammatory markers for identifying sepsis are less studied in children. The main aim of this study was to compare the levels of high-mobility group box-1 protein (HMGB1), Lipopolysaccharide-binding protein (LBP), Interleukin-6 (IL-6) and C-reactive protein (CRP) between infected children without systemic inflammatory response syndrome (SIRS) and children with severe and less severe sepsis. The second aim was to examine HMGB1, LBP, IL6 and CRP as markers for of bacteraemia. Methods Totally, 140 children with suspected or proven infections admitted to the Children's Clinical University Hospital of Latvia during 2008 and 2009 were included. Clinical and demographical information as well as infection focus were assessed in all patients. HMGB1, LBP, IL-6 and CRP blood samples were determined. Children with suspected or diagnosed infections were categorized into three groups of severity of infection: (i) infected without SIRS (n = 36), (ii) sepsis (n = 91) and, (iii) severe sepsis (n = 13). They were furthermore classified according bacteraemia into (i) bacteremia (n = 30) and (ii) no bacteraemia (n = 74). Results There was no statistically significant difference in HMGB1 levels between children with different levels of sepsis or with and without bacteraemia. The levels of LBP, IL-6 and CRP were statistically significantly higher among patients with sepsis compared to those infected but without SIRS (p < 0.001). Furthermore, LBP, IL-6 and CRP were significantly higher in children with severe sepsis compared to those ones with less severe sepsis (p < 0.001). Median values of LBP, IL6 and CRP were significantly higher in children with bacteraemia compared to those without bacteraemia. The area under the receiver operating curve (ROC) for detecting bacteraemia was 0.87 for both IL6 and CRP and 0.82 for LBP, respectively. Conclusion Elevated levels of LBP, IL-6 and CRP were associated with a more severe level of infection in children. Whereas LBP, IL-6 and CRP seem to be good markers to detect patients with bacteraemia, HMGB1 seem to be of minor importance. LBP, IL-6 and CRP levels may serve as good biomarkers for identifying children with severe sepsis and bacteraemia and, thus, may be routinely used in clinical practice. PMID:20158885

Levels of physical activity decline throughout childhood. Children's physical self-perceptions have been found to relate to their physical activity. Understanding the relationships among physical self-perceptions, obesity, and physical activity could have important implications for interventions in children. The current study investigated the moderating effect of cardiovascular fitness (CVF, heart rate recovery from a 3-minute step test) on the relationship between obesity (BMI, waist circumference) and physical self-perceptions (athletic competence, physical appearance) in 104 fourth- and fifth-grade children from a small rural community. Hierarchical regression analyses indicated that CVF moderated the relations between BMI and waist circumference on athletic competence. For children with lower fitness, higher waist circumference was associated with lower athletic competence, while for children with higher fitness levels, higher BMI was associated with higher athletic competence. Results also indicated that both BMI and waist circumference were negatively related to physical appearance. CVF moderated these relations such that only children with lower fitness, greater BMI and waist circumference was associated with poorer physical appearance scores. Implications include the need for support of fitness programs to promote psychological well-being and to investigate the relationship between obesity and physical self-perceptions within the context of fitness.

Oral rehydration is the standard in most current guidelines for young children with acute gastroenteritis (AGE). Failure of oral rehydration can complicate the disease course, leading to morbidity due to severe dehydration. We aimed to identify prognostic factors of oral rehydration failure in children with AGE. A prospective, observational study was performed at the Emergency department, Erasmus Medical Centre, Rotterdam, The Netherlands, 2010-2012, including 802 previously healthy children, ages 1 month to 5 years with AGE. Failure of oral rehydration was defined by secondary rehydration by a nasogastric tube, or hospitalization or revisit for dehydration within 72 hours after initial emergency department visit. We observed 167 (21%) failures of oral rehydration in a population of 802 children with AGE (median 1.03 years old, interquartile range 0.4-2.1; 60% boys). In multivariate logistic regression analysis, independent predictors for failure of oral rehydration were a higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score. Early recognition of young children with AGE at risk of failure of oral rehydration therapy is important, as emphasized by the 21% therapy failure in our population. Associated with oral rehydration failure are higher Manchester Triage System urgency level, abnormal capillary refill time, and a higher clinical dehydration scale score.

Few studies in the literature have looked into the cardiovascular and metabolic effects of Obstructive Sleep Apnea Syndrome (OSAS) in children. This study aims to evaluate the metabolic profile of non-obese children with OSAS. Fifty-two children were enrolled in this study, 21 girls and 31 boys. Patients were divided into two groups: OSAS (28 children) and Snore (22 children) according to polysomnographic evaluation. All children were submitted to ENT examination, measurements of weight, height and blood pressure. Blood samples were tested for hemoglobin, hematocrit, fasting glucose, fasting insulin, triglycerides, total cholesterol, HDL, LDL, VLDL, TSH and T4. The gathered data sets were compared between groups and also within the OSAS group according to the severity of the syndrome. The children from both groups had no alterations in blood pressure levels. The results of the blood tests were normal for both groups. Results of hemoglobin, hematocrit, and HDL were all significantly higher in the Snore group when compared to the OSAS group; by their turn, VLDL levels were higher in the OSAS group. There was no statistical difference between the groups based on OSAS severity. Non-obese children with OSAS present no significant alterations in metabolic tests or blood pressure levels.

To investigate vitamin D status in children with Hashimoto thyroiditis. The study group consisted of 78 children recently diagnosed as Hashimoto thyroiditis and 74 subjects as the control group. Parameters of calcium metabolism, thyroid function tests, and 25-hydroxyvitamin D [25(OH)D] levels were measured. Vitamin D deficiency rate was significantly higher in the Hashimoto group compared with the control subjects (73.1% vs. 17.6%, p < 0.0001). In the Hashimoto group, mean 25(OH)D levels were significantly lower compared with the control group (31.2 +/- 11.5 versus 57.9 +/- 19.7 nmol/L, p < 0.001) and was inversely correlated with the anti-thyroid peroxidase (anti-TPO) levels (r = -0.30, p = 0.007). The higher vitamin D deficiency rates besides lower vitamin D levels in the Hashimoto group together with the inverse correlation between vitamin D and anti-TPO suggest that vitamin D deficiency may have a role in the autoimmune process in Hashimoto thyroiditis in children.

Similarities and differences in parenting practices of children (Mage = 10; range 8-13 years) with traumatic brain injury (TBI) and socially-typical controls were examined. In addition, parenting practices were examined as moderators between injury group status (TBI or socially-typical) and social adjustment in the peer group. Mothers completed assessments of parenting practices; children's peers reported about children's social adjustment. The mothers of children with TBI reported significantly lower levels of nurturance and significantly higher levels of restrictiveness than mothers of socially-typical children. In addition, mothers’ nurturance moderated the relation between injury group and peer rejection, such that children with TBI were more rejected by classmates compared to their socially-typical peers at low levels of maternal nurturance. The findings are interpreted as supporting the important role parents play in the development of children with a history of TBI, as well as the implications for family-level interventions.

Children with autism spectrum disorder (ASD) experience internalizing and externalizing problems at higher rates than typically developing children, which could worsen social impairment. The present study compared impairment scores (social responsiveness scale, 2nd edition; SRS-2 scores) in 57 children (3-17 years, 82.5% male) with ASD, either with or without heightened levels of anxiety or ADHD symptoms, all per parent report. Children with heightened anxiety problems showed higher scores on four SRS-2 subscales (Social Cognition, Social Communication, Social Motivation, and Restricted Interests and Repetitive Behavior). Children with heightened ADHD traits showed higher scores on two subscales (Social Communication and Social Awareness). These findings suggest similarities and differences in how social deficits in ASD may worsen with anxiety or ADHD symptoms.

Lead poisoning is a potentially devastating problem among young children. Chronic low level lead exposure can lead to learning disabilities and behavior changes such as colic, insomnia, hyperactivity, impaired growth, hearing loss and upper extremity weakness. The purpose of this cross sectional study was to determine the blood lead level in children with neurological disorders in comparison with healthy controls. Blood lead concentrations were measured by flame atomic absorption spectrometry in 100 children aged 1-10 years and suffering from various neurological disorders. One hundred age and sex-matched healthy children served as controls. The mean blood lead concentration was higher in children with neurological disorders than in controls (113.2 + or - 47.5 microg/L vs 84.7 + or - 38.0 microg/L; p<0.01). Overall, 44% of children with neurological disorders and 19% of controls were found to have increased blood lead levels, i.e.>100 microg/L. An increase in blood lead level in children might be related to neurological disorders. The measurement of blood lead level might be included in diagnostic eveluation of children with neurological disorders.

This study longitudinally investigated vocal development in Korean children from 9 to 18 months of age with and without cleft palate (CP). Utterance samples were collected from 24 children with and without CP at 9, 12, 15 and 18 months of age. Each utterance was categorised into levels of vocalisation using the Korean-translated version of the Stark Assessment of Early Vocal Development-Revised (SAEVD-R). The results showed children with CP produced a significantly higher rate of precanonical vocalisations (the combination of Levels 1, 2, and 3) and a lower rate of Level 4 and 5 vocalisations than children without CP. Both groups showed decreases in Levels 1 and 2 and increases in Level 5 from 9 to 18 months of age. A significant increase in the proportion of Level 4 vocalisations across age was observed only in children without CP. Young Korean children with CP showed lower proportions of advanced vocalisation levels characterised by canonical and complex syllable structures across 9 and 18 months of age compared to children without CP.

Although there has been considerable concern regarding cross-border industrial contamination between Mexico and the United States, there are remarkably few data. One notable case study is the smelter in El Paso, Texas. In 1974 blood lead levels higher than 40 micrograms/dl were detected in 52% of children studied near the smelter, in the adjacent Mexican community of Anapra in Ciudad Juarez, Chihuahua. Lead smelting at this plant was halted in 1985, and as a result, lead levels in air decreased sharply; consequently, children's exposure to lead and other metals should have diminished accordingly. In order to assess the effect of removal of lead emissions from the area, three geographical locations in Anapra, varying in distance from the smelter source, were evaluated for lead, arsenic, and cadmium levels in soil and for lead in blood of children. It was found that lead levels in soil were inversely correlated with distance from the smelter. Arsenic and cadmium levels in soil were constant among the three sectors. However, at residential sites closer to the smelter, a higher percentage of children was found with blood lead levels exceeding the Centers for Disease Control's action level of 10.0 micrograms/dl. In the sector closest to the border 43% of children had blood lead levels greater than 10.0 micrograms/dl. Although blood lead levels in children living in Anapra have dropped approximately fourfold in 20 years, our results indicate a moderate continued risk of lead exposure. This study demonstrates the persistent impact that may result from cross-border contamination and raises provocative questions regarding appropriate action and the responsibility for financing such action.

Mothers have been shown to have higher morning cortisol on days they go to work compared to non-workdays; however, it is unknown how maternal workday associates with child morning cortisol or the attunement of mother-child morning cortisol. This study examined the presence and stability of morning cortisol levels and slopes (i.e., cortisol awakening response or CAR) in a sample of 2-4year old children in out-of-home child care with working mothers. In addition, we examined the differential contributions of maternal workday on mother-child attunement in morning cortisol. Mother and child morning cortisol was sampled twice a day (awakening and 30min later) across four consecutive days (2 non-workdays; 2 workdays) among 47 working mothers and their young children. Mothers also reported on compliance with sampling procedures and provided demographic information. While children exhibited stability in cortisol levels, children's CARs were variable, with children's non-work CARs not predictive of work CARs. Similarly, a significant morning rise in cortisol was only found on workdays, not non-workdays. Overall, mothers had higher cortisol levels and steeper CARs than their children. Further, maternal workday moderated the attunement of mother-child morning cortisol, such that mothers and children had concordant cortisol levels on non-workdays, but discordant cortisol levels on workdays. Morning cortisol may be more variable in pre-school aged children than adults but may be similarly responsive to the social environment. Further, workday mornings may be a time of reduced mother-child cortisol attunement. Copyright © 2013 Elsevier Ltd. All rights reserved.

Chinese children are facing dual burden of malnutrition-coexistence of under-and over-nutrition. Little systematic evidence exists for explaining the simultaneous presence of under-and over-nutrition. This study aims to explore underlying mechanisms of under-and over-nutrition among children in rural China. This study used a nationwide longitudinal dataset of children (N = 5,017) from 9 provinces across China, with four exclusively categories of nutritional outcomes including under-nutrition (stunting and underweight), over-nutrition (overweight only including obesity), paradox (stunted overweight), with normal nutrition as reference. Multinomial logit models (Level-1: occasions; Level-2: children; Level-3: villages) were fitted which corrected for non-independence of observations due to geographic clustering and repeated observations of individuals. A mixture of risk factors at the individual, household and neighbourhood levels predicted under-and over-nutrition among children in rural China. Improved socioeconomic status and living in more urbanised villages reduced the risk of stunted overweight among rural children in China. Young girls appeared to have higher risk of under-nutrition, and the risk decreased with age more markedly than for boys up to age 5. From age 5 onwards, boys tended to have higher risk of under-nutrition than girls. Girls aged around 12 and older were less likely to suffer from under-nutrition, while boys' higher risk of under-nutrition persisted throughout adolescence. Children were less likely to suffer from over-nutrition compared to normal nutrition. Boys tended to have an even lower risk of over-nutrition than girls and the gender difference widened with age until adolescence. Our results have important policy implications that improving household economic status, in particular, maternal education and health insurance for children, and living environment are important to enhance rural children's nutritional status in China. Investments in early years of childhood can be effective to reduce gender inequality in nutritional health in rural China.

To evaluate whether the pediatric metabolic syndrome (MetS) or its factors are useful to detect subclinical abnormalities of cardiac, liver, and glomerular damage in an outpatient population. The population study included 799 children (age 10 ± 3 years, mean ± SD), 24% of whom were normalweight, 25% overweight, and 51% obese. Alanine-aminotransferase (ALT) levels, estimated glomerular filtration rate (eGFR) and HOMA-IR were analyzed in all children. Microalbuminuria (MA) and left ventricular (LV) geometry and function were evaluated in 501 and 247 children, respectively. MetS was defined using Cook's criteria. MetS was diagnosed in 131 children (16%). Children with MetS+ and MetS- were similar for age, gender and Tanner stage distribution. Children with MetS+ showed higher ALT levels (31 ± 19 vs 21 ± 11 IU/L, p<0.0001), LV mass (39 ± 10 vs 34 ± 10 g/h(2.7), p<0.001) and relative wall thickness (0.37 ± 0.06 vs 0.35 ± 0.05, p<0.01) than MetS-. The two groups were similar for MA and eGFR. At multiple logistic regression analysis, children MetS+ showed a higher risk (OR, 95% Cl) adjusted for confounding factors, of high ALT levels (1.71, 1.12-2.59, p=0.012) and concentric LV hypertrophy (2.17, 1.01-4.66, p=0.047) than children MetS-. The risk of preclinical liver and cardiac damage associated with the MetS phenotype was not higher than predicted by its single components. Children with MetS show a 2-fold greater risk of having high ALT levels and concentric LV hypertrophy. However, the risk of subclinical manifestations of liver and cardiac damage can be predicted equally well by the single components of the syndrome. Copyright © 2010 Elsevier Ireland Ltd.

Melamine and phthalate, mainly di-(2-ethylhexyl) phthalate (DEHP), are ubiquitously present in the general environment. We investigated whether urine melamine levels can modify the relationship between DEHP exposure and markers of early renal damage in children. A nationwide health survey for Children aged ≤12 years possibly exposed to phthalates were enrolled between August 2012 and January 2013. They were administered questionnaires to collect details regarding past DEHP exposure to phthalate-tainted foodstuffs. Urine samples were measured melamine levels, phthalate metabolites and biomarkers of renal damage, including urine microalbumin/creatinine ratio (ACR), N-acetyl-beta-d-glucosaminidase (NAG), and β2-microglobulin. The study included 224 children who had a median urine melamine level (μg/mmol creatinine) of 1.61 ranging 0.18-47.42. Positive correlations were found between urine melamine levels and urine ACR as well as urine NAG levels (both Spearman correlation coefficients r = 0.24, n = 224, p < .001). The higher the past DEHP exposure or urine melamine levels, the higher the prevalence of microalbuminuria. An interaction effect was also found between urine melamine levels and past DEHP exposure on urine ACR. Melamine levels may further modify the effect of past DEHP exposure on urine ACR in children.

Air pollution and anemia as risk factors for pneumonia in ecuadorian children: a retrospective cohort analysis

PubMed Central

2011-01-01

Background Ambient air pollution and malnutrition, particularly anemia, are risk factors for pneumonia, a leading cause of death in children under five. We simultaneously assessed these risk factors in Quito, Ecuador. Methods In 2005, we studied two socioeconomically similar neighborhoods in Quito: Lucha de los Pobres (LP) and Jaime Roldos (JR). LP had relatively high levels of air pollution (annual median PM2.5 = 20.4 μg/m3; NO2 = 29.5 μg/m3) compared to JR (annual median PM2.5 = 15.3 μg/m3; NO2 = 16.6 μg/m3). We enrolled 408 children from LP (more polluted) and 413 children from JR (less polluted). All subjects were aged 18-42 months. We obtained medical histories of prior physician visits and hospitalizations during the previous year, anthropometric nutrition data, hemoglobin levels, and hemoglobin oxygen saturation via oximetry. Results In anemic children, higher pollution exposure was significantly associated with pneumonia hospitalization (OR = 6.82, 95%CI = 1.45-32.00; P = 0.015). In non-anemic children, no difference in hospitalizations by pollution exposure status was detected (OR = 1.04, NS). Children exposed to higher levels of air pollution had more pneumonia hospitalizations (OR = 3.68, 1.09-12.44; P = 0.036), total respiratory illness (OR = 2.93, 95% CI 1.92-4.47; P < 0.001), stunting (OR = 1.88, 1.36-2.60; P < 0.001) and anemia (OR = 1.45, 1.09-1.93; P = 0.013) compared to children exposed to lower levels of air pollution. Also, children exposed to higher levels of air pollution had significantly lower oxygen saturation (92.2% ± 2.6% vs. 95.8% ± 2.2%; P < 0.0001), consistent with air pollution related dyshemoglobinemia. Conclusions Ambient air pollution is associated with rates of hospitalization for pneumonia and with physician's consultations for acute respiratory infections. Anemia may interact with air pollution to increase pneumonia hospitalizations. If confirmed in larger studies, improving nutrition-related anemia, as well as decreasing the levels of air pollution in Quito, may reduce pneumonia incidence. PMID:22050924

The aim of the present study was to identify prevalence of musculoskeletal system diseases and related factors among mothers of children with cerebral palsy. Eighty-five mothers of children with cerebral palsy were included as the treatment group, and 42 mothers of healthy children were included as the control group. Sociodemographic characteristics of all subjects were recorded. Musculoskeletal system pain was evaluated by the standardized Nordic Musculoskeletal Questionnaire, and level of depression was evaluated according to Beck's Depression Scale. Musculoskeletal system pain and depression scores of the treatment group were significantly higher than those of the control group. Most frequently reported by mothers in the treatment group was low back pain (44.7%). In multiple regression analysis, number of children, age, and functional level of the child with cerebral palsy, as well as depression level of the mother were identified as independent risk factors for musculoskeletal system pain. Mothers of children with cerebral palsy are at higher risk for musculoskeletal system pain and depression. Prevalence of musculoskeletal system pain in these mothers, especially those with older children who have lower functional statuses, should be kept in mind.

One of the most severe complications of acute respiratory infections in young children is acute stenotic laryngotracheitis (croup). The relationship between cytokine blood levels and symptoms of croup, croup severity, disease sequel, despite numerous studies is still unclear. Cytokine profile in young children with acute stenotic laryngotracheitis investigation. 112 children aged 12 min. - 36 mon. with acute stenotic laryngotracheitis which were treated at the Lviv Regional Infectious Diseases Hospital were kept under observation. Croup symptoms, levels of interleukins (IL1, IL4, IL6, IL10, IL17) in serum, DNA and RNA viruses in respiratory nasal mucus were studied; Chan croup severity was used. In the pathogenesis of croup has an important role the imbalance between inflammatory (IL1, IL6) and anti-inflammatory (IL4, IL10, IL17) cytokines, which does not reduce the intensity of inflammatory reactions and its lead to local swelling, muscle spasm, excessive production of mucus in the place of viral replication. The levels of inflammatory and anti-inflammatory cytokines in the blood serum of children with croup were significantly higher than in patients with acute laryngitis. In patients with recurrent croup, unlike patients with the first case of croup does we don't see a significant correlation between the concentrations of inflammatory and anti-inflammatory cytokine levels Conclusions: The significantly higher levels of cytokines in children with croup compared with the group of patients with acute laryngitis were found, imbalance between anti-inflammatory (IL1, IL6) cytokine levels and inflammatory (IL4, IL10, IL17) cytokine levels in children who developed recurrent croup.

In this study, the authors measured sodium and potassium concentrations in spot urine samples of preschool children on multiple days, and evaluated individual, daily, and seasonal effects. A total of 104 healthy preschool children aged 4 to 5 years were studied. Urine samples were collected from the first urine of the day after waking for three consecutive days (Monday-Wednesday) four times a year (spring, summer, autumn, winter). The authors estimated the daily urine volume as 500 mL and daily creatinine excretion as 300 mg, and used these to calculate daily sodium and potassium excretion levels. Daily sodium and potassium excretion levels and sodium to potassium ratios were highly variable. The coefficient variant in the children's excretion levels were also high within and between individuals. Sodium excretion levels and sodium to potassium ratios were higher on Monday (weekend sodium intakes) than Tuesday. Season had no effect on sodium or potassium excretion levels, but the sodium to potassium ratio was higher in summer than in winter. In conclusion, levels of urinary sodium excretion are comparatively high and those of potassium are low in preschool students, with high variability within and between individuals. ©2017 Wiley Periodicals, Inc.

An ecological approach to children's rights and participation: interrelationships and correlates of rights in different ecological systems.

Current knowledge emphasizes either a developmental or a cultural/contextual theoretical framework for understanding children's approaches to the concepts of rights and participation. This study, carried out among 1,753 Israeli adolescents (ages 15-17), uses a socioecological perspective instead to understand children's rights and participation. It examines adolescents' approaches to their rights and participation at 4 ecological levels-family, school, community, and the larger sociopolitical system-as well as a number of possible child, family, and societal correlates. It also looks at the interactions between some of these correlates. The findings show that different correlates have different links with various ecological circles. For example, girls reported higher levels of participation in the family and at school, but no significant differences were found between boys and girls in their participation in the community and at civic-political levels. Israeli Palestinians reported higher levels of participation in their schools and at the civic-political level but lower levels of participation in the family and the community compared with their Jewish counterparts. The significant interaction effect between nation and gender showed that, among Arab students, there were larger gaps between boys and girls in the different participation domains than there were among Jewish students. Furthermore, higher rates of participation in the family and lower rates of civic participation were found among students from single-parent families. This study shows that employing an ecological framework to the efforts to understand children's approaches to rights and participation is a first step in the right direction for fostering children's rights and participation. © 2013 American Orthopsychiatric Association.

Galectin-1, a recently identified peptide, is primarily released from the adipose tissue. Although galectin-1 was shown to have an anti-inflammatory effect, its specific function is not clearly understood. We aimed to evaluate the relationship of serum galectin-1 levels with clinical and laboratory parameters in childhood obesity. A total of 45 obese children (mean age: 12.1±3.1years) and 35 normal-weight children (mean age: 11.8±2.2years) were enrolled. Clinical [body mass index (BMI), waist circumference (WC), percentage of body fat and blood pressure] and biochemical [glucose, insulin, lipids, galectin-1, high-sensitive C-reactive protein (hsCRP) and leptin levels] parameters were assessed. Serum galectin-1, hsCRP and leptin levels were significantly higher in obese children than those in normal-weight children (12.4 vs 10.2ng/mL, p<0.001; 3.28 vs 0.63mg/L, p<0.001; 8.3 vs 1.2ng/mL, p<0.001, respectively). In obese children, galectin-1 levels correlated negatively with fasting glucose (r=-0.346, p=0.020) and positively with fat mass (r=0.326, p=0.026) and WC standard deviation score (SDS) (r=0.451, p=0.002). The multivariate regression analysis demonstrated that serum galectin-1 levels were significantly associated with fasting glucose and WC SDS. This study showed that obese children had significantly higher galectin-1 levels in proportion to fat mass in obese cases than those in healthy children, which may be interpreted as a compensatory increase in an attempt to improve glucose metabolism.

Elevated blood lead levels lead to permanent neurocognitive sequelae in children. Resettled refugee children in the United States are considered at high risk for elevated blood lead levels, but the prevalence of and risk factors for elevated blood lead levels before resettlement have not been described. Blood samples from children aged 6 months to 14 years from refugee camps in Thailand were tested for lead and hemoglobin. Sixty-seven children with elevated blood lead levels (venous ≥10 µg/dL) or undetectable (capillary <3.3 µg/dL) blood lead levels participated in a case-control study. Of 642 children, 33 (5.1%) had elevated blood lead levels. Children aged <2 years had the highest prevalence (14.5%). Among children aged <2 years included in a case-control study, elevated blood lead levels risk factors included hemoglobin <10 g/dL, exposure to car batteries, and taking traditional medicines. The prevalence of elevated blood lead levels among tested US-bound Burmese refugee children was higher than the current US prevalence, and was especially high among children <2 years old. Refugee children may arrive in the United States with elevated blood lead levels. A population-specific understanding of preexisting lead exposures can enhance postarrival lead-poisoning prevention efforts, based on Centers for Disease Control and Prevention recommendations for resettled refugee children, and can lead to remediation efforts overseas.

Recent public health lead crises in urban areas emphasize the need to better understand exposure to environmental toxicants, particularly in higher risk groups. Although African-American children have the highest prevalence of elevated blood lead levels in the United States, little is known about when this trajectory of disproportionate burden of lead exposure first emerges. Using tooth-matrix biomarkers that directly measure fetal and early childhood metal levels, the primary goal of this study was to determine if there were racial disparities in lead levels during fetal development and early childhood. Manganese, an essential nutrient that modifies the neurotoxic effects of lead, was also measured. Pregnant women served by the Henry Ford Health System and living in a predefined geographic area in and around Detroit, Michigan, were recruited during the second trimester or later into the Wayne County Health, Environment, Allergy and Asthma Longitudinal Study (WHEALS), a population-based birth cohort. Offspring born between September 2003 and December 2007 were studied in childhood. Child race was parent-reported. Lead and manganese during the second and third trimesters, early postnatal life (birth through age 1year) and early childhood (age 1 through time of tooth shedding, which ranges from 6 to 12years) were measured via high-resolution microspatial mapping of dentin growth rings, a validated biomarker for prenatal and childhood metal exposure. African-American children (N=71) had 2.2 times higher lead levels in the second and third trimesters (both p<0.001) and 1.9 times higher lead levels postnatally in the first year of life (p=0.003) compared to white children (N=51). Lead levels in African-American children were also higher during childhood, but this effect was only marginally significant (p=0.066) and was attenuated after covariate adjustment. Additionally, we observed that African-American children had lower tooth‑manganese levels during the third trimester (p=0.063) and postnatally (p=0.043), however these differences were attenuated after covariate adjustment. The disproportionate burden of lead exposure is vertically transmitted (i.e., mother-to-child) to African-American children before they are born and persists into early childhood. Our results suggest that testing women for lead during pregnancy (or in pre-conception planning), may be needed to identify the risk to their future offspring, particularly for African-American women.

Osteoprotegerin (OPG) is a secreted member of the TNF receptor superfamily. OPG is made by osteoblastic cells and is expressed in a wide variety of cell and tissue types. It acts as a decoy receptor by binding the receptor activator of nuclear factors kB (RANKL) and preventing RANKL-induced osteoclast formation and differentiation. Numerous cytokines and hormones (TGF-beta, PTH, vitamin D, glucocorticoids and oestrogens) exert their effects on osteoclastogenesis by regulating the production of OPG. In the present study we compared serum OPG and RANKL concentrations in a group of normal children (1-14 years old) with those of pair-aged children affected by different diseases [Turner's syndrome (TS), early/precocious puberty (PP) and rheumatoid arthritis (RA)]. OPG and RANKL concentrations were measured by an enzyme immunoassay method using a commercial kit. Mean (+/- SD) OPG level in normal children was 4.05 +/- 1.63 pmol/l with no difference between males and females. OPG values in children 1-4 years old (5.87 +/- 2.22 pmol/l) were significantly higher than in children 4-14 years old (3.55 +/- 0.97 pmol/l). OPG levels in children with RA were significantly higher than in controls (6.33 +/- 2.57 pmol/l vs. 4.05 +/- 1.63 pmol/l, P < 0.01); patients with TS or PP had OPG levels superimposable to those of controls (2.61 +/- 0.67 pmol/l and 3.99 +/- 0.85 pmol/l, respectively), but in TS OPG levels were significantly lower than in age-matched females. Mean RANKL concentration in normal subjects was 0.81 +/- 1.55 pmol/l; there was a slight decline in RANKL levels with age. RANKL concentrations in subjects with TS, PP, RA and controls did not differ significantly, and did not differ from those published in adult normal subjects. It appears from our data that OPG serum levels in healthy children aged > 4 years are similar to those present in young adult men, with higher levels in the first 4 years of life. Although the meaning of the alterations of OPG levels observed in pathological conditions is still obscure, they appear potentially interesting in view of a key role played by this protein in bone homeostasis.

Motor Skills and Free-Living Physical Activity Showed No Association Among Preschoolers in 2012 U.S. National Youth Fitness Survey.

PubMed

Loprinzi, Paul D; Frith, Emily

2017-04-01

Albeit limited, some emerging work, using convenience-based samples, has demonstrated that greater motor skill development is associated with higher physical activity among preschool-aged children. The purpose of this study was to evaluate this topic using data from the 2012 National Youth Fitness Survey that included 329 preschool-aged children (3-5 years). Parents proxy-reported their child's physical activity, with motor skill level assessed from the Test of Gross Motor Development-Second Edition (TGMD2). Motor skill levels (Gross Motor Quotient, locomotor or object control) were not associated with preschool free-living physical activity in any analytic model. Thus, in this large sample of preschoolers, contrary to research with older children, motor skill level was not associated with physical activity. Findings are discussed in terms of study limitations of (a) a reliance on parent report of children's physical activity levels and (b) the possibility that physical activity data within the national survey were too limited in range to show possible associations to motor skill development with higher levels of free-living physical activity in preschoolers.

In a survey carried out in 1981, Pb exposure of children living in two geographical areas of the district of Scandiano and attending the first year of primary school was studied. The two areas were different concerning both traffic and the presence of ceramic tile industries, thus suggesting a different exposure of children. The survey demonstrated blood lead levels (PbB) markedly higher than 10 micrograms/100 ml, a value recently identified by the Centers for Disease Control (CDC, Atlanta, USA) as the limit beyond which children's learning capacity may be damaged. It was evident that both the occupational exposure of parents and, to a lower extent, the residence in zones with higher levels of pollution influenced PbB levels. During the last ten years significant improvements have led to the reduction of atmospheric emissions and of occupational exposure of ceramic workers. A new survey has been carried out in 1995. We examined 147 children attending the first year of primary school, and living in two zones for which a different level of Pb exposure could be assumed. In both zones, a clear reduction of PbB was observed in comparison with data obtained in 1981. Mean and standard deviation for PbB in the two groups were 4.1 +/- 1.71 and 4.5 +/- 2.04 micrograms/100 ml, with median values of 3.7 and 4.0 micrograms/100 ml, respectively. Only two cases (1.4%) exceeded the limit values proposed by CDC. Although the mean PbB were much lower than those observed in 1981, higher PbB were found in children whose parents were occupationally exposed to Pb. Maternal exposure seems to be particularly important in determining PbB in children. In comparison with data from the international literature, our results are very close to those obtained for children living in Scandinavian countries, in Germany or in France and rather different from those obtained by other authors in Italy.

The purpose of this study was to analyze the alpha-amylase (sAA) and cortisol levels in children with Global developmental delay (GDD) before and after dental treatment and its association with the children's behavior during treatment. The morning salivary cortisol levels and activity of sAA of 33 children with GDD were evaluated before and after dental treatment and were compared to 19 healthy children. The behavior of children with GDD during dental care was assessed by the Frankl scale. Children with GDD showed lower levels of sAA activity than healthy children, but this result was not significant. The salivary cortisol levels were similar between GDD and healthy children. GDD children showed increased levels of sAA (but not cortisol) prior to the dental treatment as compared to the post-treatment phase. GDD children who showed less favorable behavior during dental care had higher levels of sAA and salivary cortisol than GDD children with more favorable behavior, but only the sAA results were significant. In conclusion, GDD children show hyperactivity of the SNS-axis in anticipation of dental treatment which indicates the need for strategies to reduce their anxiety levels before and during dental care.

The purpose of this study was to determine the levels of urinary triclosan (TCS), benzophenone-3 (BP-3), and bisphenol A (BPA) in 52 children and 71 adolescents. The effects of age and sex on the levels of urinary TCS, BP-3, and BPA were explored, respectively. Results demonstrated the overall detection rates of urinary TCS, BP-3, and BPA were 18.7%, 8.1%, and 49.6%, respectively. The females had higher TCS concentrations than males (p = 0.051). The detection rate of urinary BP-3 in females (12.3%) was higher than that in males (0%) (p = 0.015). Moreover, the detection rate of urinary BP-3 in adolescents (14.1%) was higher than that in children (0%) (p = 0.005). For children, no urinary BP-3 was found. There were no differences in detection rates and concentrations of urinary TCS, BP-3, and BPA between males and females, respectively. For adolescents, urinary BP-3 was only found in the females. Urinary TCS levels in females were higher than those in males (p = 0.047). The present study showed that urinary TCS concentrations in females were significantly higher than those in males, respectively. In addition, BP-3 was only detected in urine samples of female adolescents. Sex and age were the important factors influencing urinary TCS and BP-3 concentrations. PMID:29232866

Diabetes education is an essential tool to achieve treatment objectives in type1 diabetes mellitus (T1DM). The aim of this study was to determine if understanding of diabetes by caregivers/patients or sociodemographic factors affect blood glucose control in children and adolescents with T1DM. The level of knowledge of 105 caregivers of children and adolescents with T1DM was assessed using a survey adapted to the type of treatment used (multiple dose insulin [MDI] or continuous subcutaneous insulin infusion [CSII]). Mean HbA1c levels in the previous year was considered as metabolic control marker. Mean HbA1c levels were similar in both treatment groups, with slightly higher values in children over 12years of age. Patients on CSII had a longer time since disease onset and had poorer results, maybe because the items were more difficult due to the higher level of knowledge required for this treatment modality (P=.005). Caregivers with lower educational levels achieved poorer scores in the survey, but mean HbA1c levels of their children were lower, probably because of their greater involvement in disease care. The level of knowledge of caregivers and/or patients with T1DM was high, and this was associated to good metabolic control. Studies to assess the impact of caregiver knowledge on metabolic control of children are needed. Copyright © 2016 SEEN. Publicado por Elsevier España, S.L.U. All rights reserved.

The matrix metalloproteinase-9 (MMP-9) and neutrophil gelatinase associated lipocalin (NGAL) are shown to increase in an inflammatory situation. Based on our previous reports that NGAL can be detected in the urine of children with urinary tract infection (UTI), we also asked whether MMP-9/NGAL complex could be detected in the urine of children with UTI. This multicenter, prospective study was conducted between October 2009 and October 2010. Seventy-one patients with symptomatic culture proven UTI, 37 asymptomatic children with contaminated urine and 37 healthy children were recruited. Mean uMMP-9/NGAL/Cr levels were significantly higher in the UTI group than in the control group (p < 0.0001). According to ROC analysis, the optimal cut-off level was 0.08 ng/mg to predict UTI. Using a cut-off value, sensitivity and specificity were 98.6 and 97.3%, respectively. The mean levels of uMMP-9/NGAL/cr in the UTI group were also significantly higher than those in the contamination group (p < 0.0001). There was no statistically significant difference between contamination group and the control group (p = 0.21). The mean uMMP-9/NGAL/Cr in the UTI group were significantly higher before treatment than after treatment (p < 0.0001). The area under the curve was 0.997 (SE: 0.002, 95% CI: 0.993 to 1.001) for uMMP-9/NGAL/Cr. Urinary MMP-9/NGAL/Cr level was also correlated with positive urine nitrite test, positive urine leukocyte esterase reaction and renal scarring (p = 0.0001, p = 0.0001, p = 0.04, respectively) whereas was not correlated to leukocytosis and positive CRP level in serum. Urine MMP-9/NGAL/cr can be used as a diagnostic biomarker for UTI in children. Identification of NGAL-MMP-9/cr levels in the urine of suspected UTI patients may also be useful to differentiate between contamination and infection and for monitoring of treatment response in children.

To evaluate i) the frequency of typical hypothyroidism symptoms in children with subclinical hypothyroidism (SH), ii) to evaluate the association of SH with lipoproteins and iii) to investigate possible improving effects of L-thyroxine (LT4) treatment on these findings. Twenty-seven children with SH who had elevated thyroid-stimulating hormone (TSH: >4.94 µIU/L) but normal free T4 levels and healthy euthyroid children of similar age and sex were enrolled in the study. Anthropometric and laboratory (lipid profile and thyroid function tests) measurements were performed at diagnosis and six months after euthyroidism was achieved. All children were also subjected to a questionnaire on hypothyroid symptoms at diagnosis. The SH patients were subjected to the questionnaire also following treatment. Pre-treatment data were compared with those of controls and post-treatment measurements. Anthropometric and laboratory parameters of the groups were not statistically different except for higher TSH levels in the SH group. Serum lipoprotein levels and dyslipidemia frequency were similar between the groups. Compared to the controls, hypothyroidism symptom score was significantly higher in the SH group. Six months after euthyroidism was achieved, a significant reduction in the hypothyroid symptom score was obtained in the SH group. Except for significantly higher serum TSH values, no significant differences regarding demographic characteristics, symptom scores and lipid parameters were present between patients with Hashimoto's thyroiditis and the remaining SH patients. The results of this study showed that in children with SH i) the hypothyroidism symptom score was significantly higher than in euthyroid children, ii) LT4 treatment improved the hypothyroidism symptom score and iii) SH does not seem to be associated with dyslipidemia.

This study used a genetically informed design to assess the effects of friends' and nonfriends' reticent and dominant behaviors on children's observed social reticence in a competitive situation. Potential gene-environment correlations (rGE) and gene-environment interactions (GxE) in the link between (a) friends' and nonfriends' behaviors and (b) children's social reticence were examined. The sample comprised 466 twin children (i.e., the target children), each of whom was assessed in kindergarten together with a same-sex friend and two nonfriend classmates of either sex. Multilevel regression analyses revealed that children with a genetic disposition for social reticence showed more reticent behavior in the competitive situation and were more likely to affiliate with reticent friends (i.e., rGE). Moreover, a higher level of children's reticent behavior was predicted by their friends' higher social reticence (particularly for girls) and their friends' higher social dominance, independently of children's genetic disposition. Children's social reticence was also predicted by their nonfriends' behaviors. Specifically, children were less reticent when male nonfriends showed high levels of social reticence in the competitive situation, and this was particularly true for children with a genetic disposition for social reticence (i.e., GxE). Moreover, children genetically vulnerable for social reticence seemed to foster dominant behavior in their female nonfriend peers (i.e., rGE). In turn, male nonfriends seemed to be more dominant as soon as the target children were reticent, even if the target children did not have a stable genetic disposition for this behavior.

The current study was conducted to evaluate the nature of association of ABO blood type with helminth infection and related reduction in haemoglobin concentration. Stool samples were collected from 403 school-age children attending Tikur Wuha Elementary School from February to April 2011. Helminth infection was examined using formol-ether concentration and thick Kato-Katz (two slides per stool specimen) techniques. Haemoglobin level was determined using a HemoCue machine and ABO blood type was determined using the antisera haemagglutination test. Nutritional status was assessed using height and weight measurements. Out of 403 children examined, 169, 120, 96 and 18 had blood type O, A, B and AB, respectively. The prevalences of helminth infections were 46.9% for hookworm, 24.6% for Schistosoma mansoni, 4.2% for Ascaris lumbricoides, 1.7% for Trichuris trichiura and 58.3% for any helminth species. The relative odds of infection with at least one helminth species was significantly higher among children with blood type A (adjusted odds ratio (AOR), 2.10; 95% confidence interval (CI), 1.28-3.45) or blood type B (AOR, 2.08; 95% CI, 1.22-3.56) as compared to children with blood type O. Among children infected with helminths, mean haemoglobin concentration was lower in those with blood type A than those with blood type O (β, -0.36; 95% CI, -0.72 to -0.01). The relative odds of hookworm infection (AOR, 1.78; 95% CI, 1.08-2.92) and related reduction in haemogobin levels (β, -0.45; 95% CI, -0.84 to -0.04) was higher among children with blood type A as compared to those with blood type O. Although the difference was not significant, the relative odds of S. mansoni or A. lumbricoides infections and related reduction in haemoglobin levels was also higher in children with blood type A or B as compared to children with blood type O. In conclusion, children with blood type A are associated with an increased risk of helminth, particularly hookworm, infection and related reduction in haemoglobin level. The mechanisms by which blood type A makes children susceptible to helminth infection and a related reduction in haemoglobin level ought to be investigated.

Children affected by HIV and AIDS have significantly higher rates of mental health problems than unaffected children. There is a need for research to examine how social support functions as a source of resiliency for children in high HIV-prevalence settings such as South Africa. The purpose of this research was to explore how family social support relates to depression, anxiety, and post-traumatic stress (PTS). Using the ecological model as a frame, data were drawn from a 2011 cross-sectional study of 1380 children classified as either orphaned by AIDS and/or living with an AIDS sick family member. The children were from high-poverty, high HIV-prevalent rural and urban communities in South Africa. Social support was analyzed in depth by examining the source (e.g. caregiver, sibling) and the type (e.g. emotional, instrumental, quality). These variables were entered into multiple regression analyses to estimate the most parsimonious regression models to show the relationships between social support and depression, anxiety, and PTS symptoms among the children. Siblings emerged as the most consistent source of social support on mental health. Overall caregiver and sibling support explained 13% variance in depression, 12% in anxiety, and 11% in PTS. Emotional support was the most frequent type of social support associated with mental health in all regression models, with higher levels of quality and instrumental support having the strongest relation to positive mental health outcomes. Although instrumental and quality support from siblings were related to positive mental health, unexpectedly, the higher the level of emotional support received from a sibling resulted in the child reporting more symptoms of depression, anxiety, and PTS. The opposite was true for emotional support provided via caregivers, higher levels of this support was related to lower levels of all mental health symptoms. Sex was significant in all regressions, indicating the presence of moderation.

Young Indigenous children in North America suffer from a higher degree of severe early childhood caries (S-ECC) than the general population, leading to speculation that the etiology and characteristics of the disease may be distinct in this population. To address this knowledge gap, we conducted the first microbiome analysis of an Indigenous population using modern molecular techniques. We investigated the caries-associated microbiome among Canadian First Nations children with S-ECC. Thirty First Nations children <72 mo of age with S-ECC and 20 caries-free children were recruited in Winnipeg, Canada. Parents or caregivers completed a questionnaire on general and dental health, diet, and demographics. The plaque microbiome was investigated by sequencing the 16S rRNA gene. Sequences were clustered into operational taxonomic units and taxonomy assigned via the Human Oral Microbiome Database, then analyzed at the community level with alpha and beta diversity measures. Compared with those who were caries free, children with S-ECC came from households with lower income; they were more likely to live in First Nations communities and were more likely to be bottle-fed; and they were weaned from the bottle at a later age. The microbial communities of the S-ECC and caries-free groups did not differ in terms of species richness or phylogenetic diversity. Beta diversity analysis showed that the samples significantly clustered into groups based on caries status. Twenty-eight species-level operational taxonomic units were significantly different between the groups, including Veillonella HOT 780 and Porphyromonas HOT 284, which were 4.6- and 9-fold higher, respectively, in the S-ECC group, and Streptococcus gordonii and Streptococcus sanguinis, which were 5- and 2-fold higher, respectively, in the caries-free group. Extremely high levels of Streptococcus mutans were detected in the S-ECC group. Overall, First Nations children with S-ECC have a significantly different plaque microbiome than their caries-free counterparts, with the S-ECC group containing higher levels of known cariogenic organisms.

The COPHES/DEMOCOPHES twin project was performed in 2011-2012 in 17 European countries to harmonize all steps of the human biomonitoring survey. Urinary cadmium, cotinine, phthalate metabolites, and hair mercury were measured in children (N = 120, 6-11 years) and their mothers of reproductive age, living in urban or rural areas. Cadmium in mothers' and children's urine was detected at a geometric mean (GM) concentration 0.227 and 0.109 μg/L, respectively; 95th percentile (P95) was 0.655 and 0.280 μg/L in mothers and children, respectively. No age-related, education-related, or urban versus rural differences were observed within the frame of each population group. Cadmium urinary level in mothers was about twofold compared with children. Higher levels were obtained in all smoking mothers but not in occasionally smoking or mothers and children exposed to environmental tobacco smoke (ETS). Mercury values in mothers were significantly higher in urban than in rural populations but not in children. GM and P95 for mercury in children's hair were 0.098 and 0.439 μg/g and in mothers' hair were 0.155 and 0.570 μg/g. Concentrations for mercury in the Czech samples were lower than European average. Hair mercury increased significantly with consumption of fish or seafood and with number of amalgam tooth fillings (in children). A positive association was found with family educational level. No influence of age was observed. Urinary cadmium and hair mercury levels were lower than health-based guidelines with one exception. High levels of urinary cotinine were found in the 12 smoking mothers (GM approximately 500 μg/L); lower levels in occasionally smoking mothers, N = 11 (34.5 μg/L). The mean cotinine levels in nonsmoking mothers who reported daily exposure to ETS was 10.7 μg/L. A similar mean value (10.8 μg/L) was obtained in six children who had daily exposure to ETS. In children without exposure to ETS, the mean cotinine level was 1.39 μg/L urine. Cotinine in the urine of children demonstrates limited protection of the Czech children against exposure to ETS.

OBJECTIVE: To test the hypothesis that societal rates of corporal punishment of children predict societal levels of violence, using "culture" as the unit of analysis. DESIGN: Data were retrieved from the Standard Cross-Cultural Sample of anthropological records, which includes 186 cultural groups, to represent the world's 200 provinces based on diversity of language, economy, political organization, descent, and historical time. Independent coders rated the frequency and harshness of corporal punishment of children, inculcation of aggression in children, warfare, interpersonal violence among adults, and demographic, socioeconomic, and parenting covariates. RESULTS: More frequent use of corporal punishment was related to higher rates of inculcation of aggression in children, warfare, and interpersonal violence. These relations held for inculcation of aggression in children and warfare after controlling for demographic, socioeconomic, and parenting confounds. CONCLUSION: More frequent use of corporal punishment is related to higher prevalence of violence and endorsement of violence at a societal level. The findings are consistent with theories that adult violence becomes more prevalent in contexts in which corporal punishment is frequent, that the use of corporal punishment increases the probability that children will engage in violent behaviors during adulthood, and that violence in one social domain tends to influence behavior in other domains. If corporal punishment leads to higher levels of societal violence, then reducing parents' use of corporal punishment should lead to reductions in societal violence manifested in other ways.

Objectives Dental caries disproportionately affects disadvantaged subjects. This study hypothesized that there were greater caries extent and higher levels of caries-associated and anaerobic subgingival bacterial species in oral samples of Hispanic and immigrant children compared with non-Hispanic and US born children. Methods Children from a school-based dental clinic serving a community with a large Hispanic component were examined, and the extent of caries was recorded. Microbial samples were taken from teeth and the tongues of children. Samples were analyzed using DNA probes to 18 oral bacterial species. Results Seventy five children were examined. Extent of caries increased with child age in immigrant, but not in US born or Hispanic children. There were no differences in the microbiota based on ethnicity or whether the child was born in US or not. There was a higher species detection frequency from teeth than tongue samples. Levels of Streptococcus mutans and other Streptococcus species increased with caries extent. Prevotella intermedia, Tannerella forsythia and Selenomonas species were detected at low levels in these children. Conclusions We conclude that, while there was a high rate of dental caries in disadvantaged school children, there were no differences in the caries-associated microbiota, including S. mutans, based on ethnicity or immigration status. Furthermore, while anaerobic subgingival, periodontal pathogens were also detected in children, there was no difference in species detection based on ethnicity or immigration status. Increased levels of streptococci, including S. mutans, however, were detected with high caries levels. This suggested that while it is beneficial to target preventive and treatment programs to disadvantaged populations, there is likely no additional benefit to focus on subgroups within a population already at high risk for dental disease.

In a recent study, we found that Greenlandic Inuit children had a more adverse metabolic profile than Danish children. Aerobic fitness and adiposity could only partly account for the differences. Therefore, we set out to evaluate and compare plasma leptin and adiponectin levels in Danish and Inuit children. In total, 187 Inuit and 132 Danish children (5.7-17.1 years) had examinations of anthropometrics, body fat content, pubertal staging, fasting blood and aerobic fitness. Plasma leptin was higher in Danish boys [3,774 (4,741-3,005)] [pg/mL unadjusted geometric mean (95% CI)] compared to both northern [2,076 (2,525-1,706)] (p < 0.001) and southern (2,515 (3,137-2,016)) (p < 0.001) living Inuit boys and higher in Danish girls [6,988 (8,353-5,847)] compared to southern living Inuit girls [4,910 (6,370-3,785)] (p = 0.021) and tended to be higher compared to northern living Inuit girls [5,131 (6,444-4,085)] (p = 0.052). Plasma adiponectin was higher for both Danish boys [22,359 (2,573-19,428)] [ng/mL unadjusted geometric mean (95% CI)] and girls [26,609 (28,994-24,420)] compared to southern living Inuit boys [15,306 (18,406-12,728)] and girls [18,864 (22,640-15,717)] (both p < 0.001), respectively. All differences remained after adjustment for body fat percentage (BF%), aerobic fitness, age and puberty. The leptin/adiponectin ratio was higher in Danish boys and tended to be higher in Danish girls compared to northern living Inuit boys and girls, respectively. These differences were eliminated after adjustment for BF%, aerobic fitness, age and puberty. In contrast to our hypothesis, plasma leptin was higher in Danish children despite a more healthy metabolic profile compared to Inuit children. As expected, plasma adiponectin was lowest in Inuit children with the most adverse metabolic profile.

Maternal educational level, parental preventive behavior, risk behavior, social support and medical care consumption in 8-month-old children in Malmö, Sweden

2011-01-01

Background The social environment in which children grow up is closely associated with their health. The aim of this study was to investigate the relationship between maternal educational level, parental preventive behavior, parental risk behavior, social support, and use of medical care in small children in Malmö, Sweden. We also wanted to investigate whether potential differences in child medical care consumption could be explained by differences in parental behavior and social support. Methods This study was population-based and cross-sectional. The study population was 8 month-old children in Malmö, visiting the Child Health Care centers during 2003-2007 for their 8-months check-up, and whose parents answered a self-administered questionnaire (n = 9,289 children). Results Exclusive breast feeding ≥4 months was more common among mothers with higher educational level. Smoking during pregnancy was five times more common among less-educated mothers. Presence of secondhand tobacco smoke during the first four weeks of life was also much more common among children with less-educated mothers. Less-educated mothers more often experienced low emotional support and low practical support than mothers with higher levels of education (>12 years of education). Increased exposure to unfavorable parental behavioral factors (maternal smoking during pregnancy, secondhand tobacco smoke and exclusive breastfeeding <4 months) was associated with increased odds of in-hospital care and having sought care from a doctor during the last 8 months. The odds were doubled when exposed to all three risk factors. Furthermore, children of less-educated mothers had increased odds of in-hospital care (OR = 1.34 (95% CI: 1.08, 1.66)) and having sought care from a doctor during the last 8 months (OR = 1.28 (95% CI: 1.09, 1.50)), which were reduced and turned statistically non-significant after adjustment for unfavorable parental behavioral factors. Conclusion Children of less-educated mothers were exposed to more health risks, fewer health-promoting factors, worse social support, and had higher medical care consumption than children with higher educated mothers. After adjustment for parental behavioral factors the excess odds of doctor's visits and in-hospital care among children with less-educated mothers were reduced. Improving children's health calls for policies targeting parents' health-related behaviors and social support. PMID:22114765

Background Children with callous-unemotional (CU) traits may have a particularly malevolent view of social conflicts and a pervasive insensitivity to others' distress. The current study examined whether children with CU traits have unique expectations and values regarding the consequences of aggressive conflicts and a ubiquitous lack of concern for others' feelings independent of co-occurring aggression. Methods Participants were 96 (46 males, 50 females) children recruited from elementary schools within an urban city. Associations between CU traits and child reports of outcome expectancies/values following aggressive conflicts and facets of empathy were examined after controlling for aggression, academic abilities, and demographic covariates. Results Children with higher CU traits were less likely to expect that aggression would result in victim suffering and feelings of remorse. After controlling for co-occurring aggression, children with higher CU traits were more likely to expect that aggression would result in peer dominance, while children with higher levels of aggression were more likely to expect that attacking others would reduce their aversive behavior. Children with higher CU traits were less concerned that aggressive behavior would result in punishment, victim suffering, and feelings of remorse. Moreover, children with higher CU traits reported lower levels of empathetic concern and sadness in response to others' distress outside of aggressive conflicts. Conclusions Children with CU traits tend to minimize the extent to which aggression causes victim suffering and openly acknowledge caring less about distress and suffering in others. They are less intimidated by the possibility of being punished for aggressive behavior and tend to view aggression as an effective means for dominating others. In sum, children with CU traits have a particularly malicious social schema that may be difficult to change using conventional treatment methods. PMID:22066467

Moreover, children with higher CU traits reported lower levels of empathetic concern and sadness in response to others' distress outside of aggressive conflicts. Children with CU traits tend to minimize the extent to which aggression causes victim suffering and openly acknowledge caring less about distress and suffering in others. They are less intimidated by the possibility of being punished for aggressive behavior and tend to view aggression as an effective means for dominating others. In sum, children with CU traits have a particularly malicious social schema that may be difficult to change using conventional treatment methods. © 2011 The Authors.

The associations of maternal caffeine intake during pregnancy with offspring growth patterns and body fat and insulin levels at school age were examined. In a population-based birth cohort among 7,857 mothers and their children, maternal caffeine intake during pregnancy was assessed by questionnaires. Growth characteristics were measured from birth onward. At 6 years, body fat and insulin levels were measured. Compared to children whose mothers consumed <2 units of caffeine per day during pregnancy (1 unit of caffeine is equivalent to 1 cup of coffee (90 mg caffeine)), those whose mothers consumed ≥6 units of caffeine per day tended to have a lower weight at birth, higher weight gain from birth to 6 years, and higher body mass index from 6 months to 6 years. Both children whose mothers consumed 4-5.9 and ≥6 units of caffeine per day during pregnancy tended to have a higher childhood body mass index and total body fat mass. Only children whose mothers consumed ≥6 units of caffeine per day had a higher android/gynoid fat mass ratio. These results suggest that high levels of maternal caffeine intake during pregnancy are associated with adverse offspring growth patterns and childhood body fat distribution. © 2016 The Obesity Society.

2011-11-01

Hartmann-Shack images taken from an archived collection of SureSight refractive measurements of pre-school children in Oxford County, Ontario, Canada were retrieved and re-analyzed. Higher-order aberrations were calculated over the age range of 3 to 6 years. These higher-order aberrations were compared with respect to magnitudes of ametropia. Subjects were classified as emmetropic (range -0.5 to + 0.5D), low hyperopic (+ 0.5 to +2D) and high hyperopic (+2D or more) based upon the resulting spherical equivalent. Higher-order aberrations were found to increase with higher levels of hyperopia (p < 0.01). The strongest effect was for children showing more than +2.00D of hyperopia. The correlation coefficients were small in all of the higher-order aberrations; however, they were significant (p < 0.01). These analyses indicate a weak association between refractive error and higher-order aberrations in pre-school children.

Abstract Objective: To analyze the associations between socioeconomic status (SES) indicators and physical activity and overweight/obesity in children. Methods: 485 children wore accelerometers for 7 days. Variables included time in sedentary behavior and moderate-to-vigorous physical activity (MVPA), and steps/day. Children were further categorized as meeting or not meeting guidelines of ≥60min/day MVPA and ≥12,000 steps/day. Body mass index (BMI) and body fat percentage (BF%) were measured using bioelectrical impedance. Overweight/obesity was defined as BMI >+1 SD and BF% ≥85th percentile. Parents answered questionnaires that questioned total annual household income, parental education level, parental employment status and automobile ownership. Results: Children averaged 59.5min/day in MVPA (44.1% met MVPA guidelines), and 9639 steps/day (18.4% met steps/day guidelines). 45.4% and 33% were overweight/obese classified by BMI and BF% respectively. Higher relative total annual household income level (Odds Ratio 0.31; 95% confidence interval=0.15-0.65), and relatively higher maternal (OR=0.38; 95%CI=0.20-0.72) and paternal (OR=0.36; 95%CI=0.17-0.75) education levels were associated with lower odds of children meeting MVPA guidelines. Household automobile ownership was associated with lower odds of children meeting MVPA (OR=0.48; 95%CI=0.31-0.75) and steps/day guidelines (OR=0.44; 95%CI=0.26-0.74). Conclusions: SES indicators were not associated with overweight/obesity, but higher SES was associated with lower odds of children meeting MVPA guidelines. PMID:26975562

Objectives. We assessed the prevalence of elevated blood lead levels (≥ 10 micrograms of lead per deciliter of blood), risk factors, and previous blood lead testing among children in 2 high-risk Chicago, Ill, communities. Methods. Through high-intensity targeted screening, blood lead levels were tested and risks were assessed among a representative sample of children aged 1 to 5 years who were at risk for lead exposure. Results. Of the 539 children who were tested, 27% had elevated blood lead levels, and 61% had never been tested previously. Elevated blood lead levels were associated with chipped exterior house paint. Conclusions. Most of the children who lived in these communities—where the prevalence for elevated blood lead levels among children was 12 times higher than the national prevalence—were not tested for lead poisoning. Our findings highlight the need for targeted community outreach that includes testing blood lead levels in accordance with the American Academy of Pediatrics’ recommendations. PMID:15514235

Although previous research based on data from the U.S. suggests that parents' widowhood is associated with increased emotional support from children, little is known about the impact of late-life widowhood on intergenerational relationships in other cultures. Using data of Korean older adults, this paper examined: (1) the effect of widowhood on both positive and negative aspects of parent-child relationships and (2) whether these effects are moderated by older adults' expectations about children's filial responsibilities and the geographic proximity to their children. Analyses are based on data from the Hallym Aging Study, a stratified multi-stage probability sample of older adults living in the cities of Seoul and Chuncheon in Korea. Compared to married older adults, widowed persons in this sample reported higher levels of ambivalence, lower levels of positive interactions, and higher levels of negative interactions with their children. Parents' notion about filial responsibilities did not have a significant moderating effect, whereas geographic proximity to children was a significant moderator. Findings suggest that widowhood is associated with greater strain in intergenerational relationships in Korea. Helping widowed older adults forge constructive relationships with their children may enhance both bereaved older adults' and their children's well-being in this cultural milieu.

Dyslipidemia is one of the major complications of obesity; vitamin D deficiency and insulin resistance are attending metabolic complications in dyslipidemic obese children. Objective. To determine if vitamin D deficiency and insulin resistance are risk factors for dyslipidemia in obese children. This study was conducted in the Department of Pediatrics at Bagcilar Training and Research Hospital in Istanbul, Turkey between 2014 and 2015. Obese patients whose age range was 8-14 were included in the study. The serum triglyceride, total cholesterol, low-density lipoprotein cholesterol, highdensity lipoprotein cholesterol, fasting glucose, insulin, alanine aminotransferase, vitamin D levels were measured; a liver ultrasonography was performed. Homeostatic model assessment (HOMA-IR), was used to calculate insulin resistance. 108 obese children were included; 39 (36.11%) had dyslipidemia. The average fasting blood glucose (88.74 ± 7.58 vs. 95.31 ± 6.82; p= 0.0001), insulin level (14.71 ± 12.44 vs. 24.39 ± 15.02; p= 0.0001) and alanine aminotransferase level (23.45 ± 11.18 vs. 30.4 ± 18.95; p= 0.018) were significantly higher in the children with dyslipidemia. In the dyslipidemic obese children, the average hepatosteatosis rate and HOMA-IR level were higher; 28 (71.9%) had hepatosteatosis, 37 (94.87%) had insulin resistance; the vitamin D levels were <20 ng/ml in 69.3%. Vitamin D deficiency was significantly more common (p= 0.033). The multivariate regression analysis confirmed that the increase in the HOMA-IR level (p= 0.015) and the low vitamin D level (p= 0.04) were important risk factors for dyslipidemia. Obese children in our region exhibit low vitamin D and increased HOMA-IR levels, which are efficient risk factors of dyslipidemia.

Polymorphisms of delta-aminolevulinic acid dehydratase (ALAD) and peptide transporter 2 (PEPT2) genes in children with low-level lead exposure

Low-level lead exposure during early childhood has long been associated with altered neurocognitive development and diminished cognitive functions. Over nine thousand U.S. industrial facilities annually emit significant amounts of lead, creating exposure risk particularly for minority children. The mechanisms by which low-level lead exerts neurotoxic effects are poorly understood. Once absorbed, the only intervention is source removal, thus primary prevention is key. Genetic biomarkers could provide an efficient means of identifying children at greatest risk. Common functional variants of genes that alter lead's neurotoxic potential have been identified and include delta-aminolevulinic acid dehydratase (ALAD2) and peptide transporter 2 (PEPT2*2). These polymorphisms have not been examined previously in Hispanic minority samples, or with regard to lowest level lead exposure. In 116 children of Mexican-American/Hispanic descent residing in zip codes previously designated as “high risk” for lead exposure (mean age = 8.1, S.D. = 1.9), blood lead level was measured at three time points over a 3-month period and averaged. DNA extraction was completed using buccal swab samples. The frequencies of the ALAD2 and PEPT2*2 polymorphisms observed in this sample closely approximated those previously reported for Anglo, European and Asian samples. As compared to children heterozygous for the PEPT2*2 polymorphism, and without the PEPT2*2 polymorphism, the geometric mean blood lead level of children homozygous for the PEPT2*2 polymorphism was significantly higher. In contrast to past studies, mean blood lead level of children heterozygous and homozygous for the ALAD2 polymorphism in this sample did not differ from that of children without the ALAD2 polymorphism. Higher blood lead burden in children with the PEPT2*2 mutation may suggest that this common genetic variant is a biomarker of increased vulnerability to the neurotoxic effects of lowest level lead exposure.

Iron participates in oxygen transport, energetic, metabolic, and immunologic processes. There are 2 main causes of iron overload: hereditary hemochromatosis which is a primary cause, is a metabolic disorder caused by mutations of genes that control iron metabolism and secondary hemochromatosis caused by multitransfusions, chronic hemolysis, and intake of iron rich food. The most common type of hereditary hemochromatosis is caused by HFE gene mutation. In this study, we analyzed iron metabolism in 100 healthy Polish children in relation to their HFE gene status. The wild-type HFE gene was predominant being observed in 60 children (60%). Twenty-five children (25%), presented with heterozygotic H63D mutation, and 15 children (15%), presented with other mutations (heterozygotic C282Y and S65C mutation, compound heterozygotes C282Y/S65C, C282Y/H63D, H63D homozygote). The mean concentration of iron, the level of ferritin, and transferrin saturation were statistically higher in the group of HFE variants compared with the wild-type group. H63D carriers presented with higher mean concentration of iron, ferritin levels, and transferrin saturation compared with the wild-type group. Male HFE carriers presented with higher iron concentration, transferrin saturation, and ferritin levels than females. This preliminary investigation demonstrates allelic impact on potential disease progression from childhood.

In this study, we aimed to search cognitive, behavioral and psychopathological differences between children of fathers with alcohol dependency and children of fathers without alcohol dependency. Forty-six children of 34 alcoholic fathers and 36 children of 34 non-alcoholic fathers, between the ages of 6 and 16 years were evaluated. Two groups were matched with each other on the basis of socioeconomic level of family, age and gender of children. All children were screened for psychiatric disorders according to DSM-IV criterias by using the Schedule for Affective Disorders and Schizophrenia for School Aged Children, Present and Lifetime Version (K-SADS-PL). The mothers and teachers completed the Child Behavior Checklist, Teacher Report Form and Conners Parents/Teachers Rating Scales. Furthermore, Wecshler Inteligence Scale for Children-Revised (WISC-R) and Bender Gestalt Visual Motor Coordination test were applied to all children. The mothers completed Symptom Checklist-90-Revised (SCL-90-R). The findings of this research indicated that children of alcoholic fathers had a higher incidence of psychopathology. Teacher Report Form and Conners Teachers Rating Scale scores were higher in research group. It was also found that mothers in research group had higher level of psychiatric symptoms in SCL-90-R. Alcohol dependent patients are an easily available group for clinicians. It can be more realistic to treat alcohol dependency as a family disease because of associated psychiatric problems in children and mothers. In addition to alcohol dependent fathers, including mothers and children in the psychiatric assessment and treatment plans may become a preventive step for the child.

This study examined the association between interparental violence (IPV), child abuse and neglect, other traumatic experiences, and children's post-traumatic stress (PTS) symptoms and explored the moderating role of family functioning in the aftermath of IPV. One hundred and twenty IPV-exposed children (53.3 % male, M age = 9.85) and parents who were referred to community mental health centers participated in the study. Combined, IPV, child abuse and neglect, and other traumatic experiences were associated with PTS symptoms. For family functioning, higher levels of parenting stress were associated with higher levels of PTS symptoms. No moderating effects were found. To understand the variability in PTS symptoms among children exposed to IPV, other traumatic and stressful experiences need to be taken into account.

Research suggests that corporal punishment is related to higher levels of child externalizing behavior, but there has been controversy regarding whether infrequent, mild spanking predicts child externalizing or whether more severe and frequent forms of corporal punishment account for the link. Mothers rated the frequency with which they spanked and whether they spanked with a hand or object when their child was 6, 7, and 8 years old. Mothers and teachers rated children's externalizing behaviors at each age. Analyses of covariance revealed higher levels of mother-reported externalizing behavior for children who experienced harsh spanking. Structural equation models for children who experienced no spanking or mild spanking only revealed that spanking was related to concurrent and prior, but not subsequent, externalizing. Mild spanking in one year was a risk factor for harsh spanking in the next year. Findings are discussed in the context of efforts to promote children's rights to protection.

Centers of Disease Control of the United States of America (CDC) informs Ministry of Public Health, Thailand that up to 13% of Burmese refugee children who are transferred to the United States of America during 2007-2009 have elevated blood lead levels (EBLL, Blood Lead Level > or = 10 microg/dl). These are children from a number of refugee camps in Tak Province; two camps are near Umphang but other camps are not. In June 2008, CDC, the result of investigation of Centers for Disease Control/Thailand Ministry of Public Health Collaboration (CDC/TUC) and International Organization for Migration, Thailand indicates that 33 of 64 children aged 6 months to 15 years (5.1%) who live in Mae La, Umpiem and Nupo camps have elevated blood lead level. However, no study on how Thai children who live nearby those camps are exposed to lead. Subsequently, Queen Sirikit National Institute of Child Health, Bangkok, Thailand contacts relevant organizations in Tak Province in order to investigate lead exposure and evaluate health status of Thai children who live close to Burmese refugee camps. 1) Evaluation of lead exposure of Thai children who live nearby Burmese refugee camps; 2) Assessment of risk factors on lead exposure of the children as mentioned above. The present study adopts a retrospective study based on information gathered from health assessment on 213 Thai children aged between 3-7 years old who live nearby Burmese refugee camps. The health assessment was conducted from April 30th, 2010 to May 5th, 2010. The information is from 3 sources. The first source is from blood sampling in order to assess lead level and ferritin level. The next source is from interview of persons who provide primary care in order to identify risk factors on lead exposure of target children. The last source is from physical examination and developmental assessment conducted by pediatricians and special nurses for child development in order to identify health and developmental problems. The population of the present study was 213 of Thai children are 3-7 years old, average age is 54.54 +/- 12.41 months-old. The average blood lead level is 7.71 +/- 4.62 microg/dl (range = 3-25 microg/dl). Elevated blood lead levels of all populations show that 57 children (26%) have blood lead level at 10 microg/dl or more. Analysis of odds by controlling all risk factors (adjusted OR) that effect on blood lead level (> or =10 microg/dl) indicates that only gender and source of drinking water are risk factors. To clarify, male children would have 2.8 times higher risk than female children. Children who drink water from tap and canal have 15 times and 72 times, respectively, higher risk than children drinking from bottle water. The result of the present study shows that 1 of 4 of Thai children at Umphang district, Tak Province who lived near Burmese refugee camps aged between 3-7 years old have blood lead level higher than concerning level. Thus, it is necessary to identify risk factors on lead exposure and policy of blood lead screening in some areas in Thailand.

Children spend a considerable part of their day in preschool, where they may be exposed to hazardous chemicals in indoor dust. In this study, brominated flame retardants (BFRs) and organophosphate esters (OPEs) were analyzed in preschool dust ( n = 100) and children's hand wipe samples ( n = 100), and diphenyl phosphate (DPHP) was analyzed in urine ( n = 113). Here we assessed children's exposure via dust, identified predictors for chemicals in dust, and studied correlations between different exposure measures. The most abundant BFRs in dust were decabromodiphenyl ether (BDE-209) and decabromodiphenyl ethane (DBDPE) found at median levels of 270 and 110 ng/g dust, respectively. Tris(2-butoxyethyl) phosphate (TBOEP) was the most abundant OPE, found at a median level of 79 000 ng/g dust. For all OPEs and some BFRs, there were significant correlations between the levels in dust and hand wipes. In addition, triphenyl phosphate (TPHP) in preschool dust was significantly correlated with the corresponding metabolite DPHP in children's urine. The levels of pentaBDEs in dust were higher in older preschools compared with newer, whereas levels of DBDPE were higher in newer preschools. Children's estimated intakes of individual BFRs and OPEs via preschool dust were below available health-based reference values. However, there are uncertainties about the potential health effects of some emerging BFRs and OPEs.

There is a lack of consensus on the cardiometabolic consequences of mild subclinical hypothyroidism (SCH) among children. The objective of the current study was to compare lipid profiles in children with mild SCH with those of euthyroid children. Retrospective medical record review. Children (ages 2-18 years) who had undergone simultaneous measurement of TSH, free thyroxine (T4) and lipids. Lipids in children with mild SCH (TSH 5-<10 mIU/L and normal free T4, n = 228) were compared with those in euthyroid children (n = 1215). TSH level was positively associated with total cholesterol and nonhigh density lipoprotein (non-HDL) cholesterol [β 0.05(0.03-0.08), P < .0001 and β 0.05(0.03-0.08), P < .0001, respectively]. Total cholesterol was significantly higher in children and adolescents with mild SCH compared with euthyroid children (4.43 ± 1.14 mmol/L vs 4.2 ± 0.85 mmol/L, P = .0005). Similarly, non-HDL cholesterol level was also higher in children with mild SCH relative to euthyroid children (3.08 ± 1.14 mmol/L vs 2.91 ± 0.8 mmol/L, P = .001). The adjusted odds ratio of having elevated total cholesterol and elevated non-HDL cholesterol was greater in children with mild SCH compared with euthyroid children (OR 1.88, 95% CI; 1.28-2.73; P = .001 and 1.72, 95% CI 1.2-2.5; P = .003, respectively). The presence of thyroid autoimmunity was not associated with higher rates of dyslipidaemia. Mild SCH in children and adolescents was associated with higher rates of elevated total cholesterol and elevated non-HDL cholesterol. Randomized placebo controlled studies are warranted to determine if treatment of mild SCH in children leads to improvement in lipid profile. © 2018 John Wiley & Sons Ltd.

Vegetarian diet has become an increasing trend in western world and in Poland. The frequency of allergies is growing, and the effectiveness of vegetarian diet in allergic diseases is a concern for research. We aimed to study an effect of vegetarian diet on lipid profile in serum in a group of Polish children in Poland and to investigate lipid parameters in healthy vegetarian children and in omnivorous children with diagnosed atopic disease. Serum lipid profiles (triglycerides, total cholesterol, low-density lipoprotein (LDL) and high-density lipoprotein (HDL) cholesterol, fatty acids) were assessed in groups of children: healthy vegetarians (n=24) and children with diagnosed atopic diseases (n=16), with control group of healthy omnivores (n=18). Diet classification was assessed by a questionnaire. No differences were observed in serum triglycerides, LDL cholesterol and saturated and monounsaturated fatty acids level in all groups. In the group of Polish vegetarian children, we recorded high consumption of vegetable oils rich in monounsaturated fatty acid, and sunflower oil containing linoleic acid. This observation was associated with higher content of linoleic acid in serum in this group. Among polyunsaturated n-6 fatty acids, linoleic acid revealed significantly (P<0.05) lower levels in allergy vs vegetarian groups. In case of eicosapentaenoic acid (n-3 fatty acid), the allergy group showed higher levels of this compound in comparison to vegetarians. Significantly higher concentration of linoleic acid in vegetarian children in comparison to allergy group indicated possible alternative path of lipid metabolism in studied groups, and in consequence, some elements of vegetarian diet may promote protection against allergy.

Stress among Parents of Children with and without Autism Spectrum Disorder: A Comparison Involving Physiological Indicators and Parent Self-Reports.

2017-01-01

Parents of children with Autism Spectrum Disorder (ASD) have been reported as experiencing higher levels of stress and poorer physical health than parents of typically developing children. However, most of the relevant literature has been based on parental self-reports of stress and health. While research on physiological outcomes has grown in recent years, gaps still exist in our understanding of the physiological effects, if any, of stress related to parenting a child with ASD. The present study compared parent-reported stress, anxiety, and depression, as well as selected physiological measures of stress (i.e., cortisol, alpha-amylase, and ambulatory blood pressure and heart rate) between matched groups of parents of children with ( N =  38) and without ( N  = 38) ASD. Participants completed questionnaires, collected saliva samples for the purpose of measuring cortisol and alpha-amylase, and wore an ambulatory blood pressure monitor for 24 h. Parents of children with ASD reported significantly higher levels of parental distress, anxiety, and depression than parents of typically developing children. Parent-reported distress, anxiety, depression, and health were not correlated with physiological measures. With the exception that parents of children with ASD had significantly lower cortisol levels 30 min after waking, no other significant group differences were found for physiological measures. Parents of children with ASD reported significantly higher use of a number of adaptive coping strategies (e.g., emotional support) in comparison to parents of typically developing children. Results are discussed in the context of implications for future research directions, stress research, and practical implications for parental support.

Improvements in oral health care services have not reached evenly across every segment of American society. The authors examine the role of nondentist practitioners in referring child patients for dental care by analyzing data from the 2003 Medical Expenditure Panel Survey conducted by the Agency for Healthcare Research and Quality and the National Center for Health Statistics. The authors provide national estimates of the percentage of the civilian noninstitutionalized population of the United States aged 2 through 17 years who had a dental visit, who had a dental checkup and who received advice from a nondentist health care provider to have a dental checkup. Overall, 38 percent of all poor, near-poor or low-income children and 60 percent of all middle- or high-income children aged 2 through 17 years reported having had a dental checkup during 2003. The authors observed no significant differences between poor, near-poor and low-income children and higher-income children in terms of having been advised by a nondentist health care provider to have a dental checkup. Although income may not predict the likelihood of patients' receiving advice from a nondentist health care provider to have a dental checkup, children from families with higher levels of income were more likely to seek dental care than were children from families with lower levels of income. Practice Implications. Efforts to increase access to dental care should aim to maximize the benefit of advice provided by nondentist health care practitioners to receive a dental checkup, so that children from families with limited income are as likely to receive a dental checkup as are children from families with higher levels of income.

Chinese children are facing dual burden of malnutrition—coexistence of under-and over-nutrition. Little systematic evidence exists for explaining the simultaneous presence of under-and over-nutrition. This study aims to explore underlying mechanisms of under-and over-nutrition among children in rural China. This study used a nationwide longitudinal dataset of children (N = 5,017) from 9 provinces across China, with four exclusively categories of nutritional outcomes including under-nutrition (stunting and underweight), over-nutrition (overweight only including obesity), paradox (stunted overweight), with normal nutrition as reference. Multinomial logit models (Level-1: occasions; Level-2: children; Level-3: villages) were fitted which corrected for non-independence of observations due to geographic clustering and repeated observations of individuals. A mixture of risk factors at the individual, household and neighbourhood levels predicted under-and over-nutrition among children in rural China. Improved socioeconomic status and living in more urbanised villages reduced the risk of stunted overweight among rural children in China. Young girls appeared to have higher risk of under-nutrition, and the risk decreased with age more markedly than for boys up to age 5. From age 5 onwards, boys tended to have higher risk of under-nutrition than girls. Girls aged around 12 and older were less likely to suffer from under-nutrition, while boys’ higher risk of under-nutrition persisted throughout adolescence. Children were less likely to suffer from over-nutrition compared to normal nutrition. Boys tended to have an even lower risk of over-nutrition than girls and the gender difference widened with age until adolescence. Our results have important policy implications that improving household economic status, in particular, maternal education and health insurance for children, and living environment are important to enhance rural children’s nutritional status in China. Investments in early years of childhood can be effective to reduce gender inequality in nutritional health in rural China. PMID:27391448

This study investigated associations between the growth hormone/insulin-like growth factor-1 (GH/IGF-1) axis, adiponectin, resistin and metabolic profile in 47 GH-deficient children before and during 12 months of GH treatment. 23 short age-matched children without growth hormone deficiency (GHD) or any genetic or chronic disorders were recruited as controls at baseline. Metabolic evaluation included measurements of adiponectin, resistin, IGF-1, total cholesterol (total-C), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), glucose, insulin, glycated haemoglobin (HbA1c), thyroid stimulating hormone (TSH) and free thyroxine (free T4) concentrations. The GH-deficient children had significantly higher adiponectin (p<0.05) and total cholesterol (p<0.05) levels, and a significantly lower level of resistin (p<0.05) than the controls. Resistin at 6 months of GH treatment significantly correlated with changes in height SDS in that period (r=0.35) and with the level of fasting insulin (r=0.50), the HOMA-IR (r=0.56) and the QUICKI (r=-0.53) at 12 months of therapy. Adiponectin level at 12 months of GH treatment was significantly associated with changes in HDL-C within the first 6 (r=0.73) and within 12 (r=0.56) months of therapy, while resistin significantly correlated with an increment in IGF-1 within 12 months of treatment (r=0.49) and with total-C at 12 months (r=0.56). Untreated GH-deficient children had higher adiponectin and lower resistin levels than healthy short children without GHD. Adiponectin and resistin levels did not change significantly during the first 12 months of GH therapy. Good responders to GH treatment had a tendency for higher resistin level during GH therapy, which positively correlates with the insulin resistance parameters.

Children with neurodevelopmental disorders often show impairments in sensory processing (SP) and higher functions. The main objective of this study was to compare SP, praxis and social participation (SOC) in four groups of children: ASD Group (n = 21), ADHD Group (n = 21), ASD+ADHD Group (n = 21), and Comparison Group (n = 27). Participants were the parents and teachers of these children who were 5–8 years old (M = 6.32). They completed the Sensory Processing Measure (SPM) to evaluate the sensory profile, praxis and SOC of the children in both the home and classroom contexts. In the home context, the most affected was the ASD+ADHD group. The ADHD group obtained higher scores than the ASD group on the Body Awareness (BOD) subscale, indicating a higher level of dysfunction. The ASD group, however, did not obtain higher scores than the ADHD group on any subscale. In the classroom context, the most affected were the two ASD groups: the ASD+ADHD group obtained higher scores than the ADHD group on the Hearing (HEA) and Social Participation (SOC) subscales, and the ASD group obtained higher scores than the ADHD group on the SOC subscale. Regarding sensory modalities, difficulties in proprioception seem to be more characteristic to the ADHD condition. As for higher-level functioning, social difficulties seem to be more characteristic to the ASD condition. Differences between the two contexts were only found in the ASD group, which could be related to contextual hyperselectivity, an inherent autistic feature. Despite possible individual differences, specific intervention programs should be developed to improve the sensory challenges faced by children with different diagnoses. PMID:29075217

This study has explored the valence of sibship that may empower the self-esteem of children with asthma at the interpersonal, environmental control competence, emotionality management, and body-image levels. It has been assumed that the relationship between siblings may have a moderating effect on the negative impact that asthma has on child's development. Seventy children suffering from chronic asthma have been involved: 40 children with siblings (experimental group) and 30 sibling-free children (control group). The children with asthma have exhibited higher levels of self-esteem in comparison with the sibling-free children. The results of the study, at the clinical significance level, highlight how meaningful could be the involvement of healthy siblings to support the development, and to ease the compliance of children suffering from asthma. The outcomes have confirmed the supportive valence of sibship for the self-esteem of the children with asthma.

To determine serum bile acid (BA) and fatty acid (FA) profiles in Chinese children with non-alcoholic fatty liver disease (NAFLD). A total 76 children aged 4-17 years were categorized into three groups according to the presence and absence of as well as the severity of NAFLD, that is, non-NAFLD (control), mild and moderate to severe NAFLD groups, respectively, based on their liver ultrasonography findings. Serum BA and FA profiles were quantified separately by mass spectrometry and gas chromatography. General linear models were performed to assess the differences among the groups. After adjusted for potential confounders, children with NAFLD had higher levels of chenodeoxycholic acid (CDCA), unconjugated primary BAs (CDCA + cholic acid) but lower levels of deoxycholic acid (DCA), taurodeoxycholic acid (TDCA), glycodeoxycholic acid (GDCA), total DCA (DCA + TDCA + GDCA), glycolithocholic acid (GLCA) and total lithocholic acid (GLCA + taurolithocholic acid) than children without NAFLD. As for FAs, children with mild and moderate to severe NAFLD had higher levels of n-7 monounsaturated FA. Circulating BA and FA profiles may change in children with NAFLD. Further studies are needed to determine their associations and to understand the underlying mechanism of action. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

To compare the prevalence of undernutrition and anemia in indigenous and non-indigenous children < 5 years of age at the national level, by region and by urban and rural areas, and to evaluate the degree to which the socioeconomic condition of the family predicts the differences. A national probabilistic survey was conducted in Mexico in 1999. Indigenous families were identified as those in which at least one woman 12-49 years of age in the household spoke a native language. The prevalence of undernutrition (stunting, wasting and underweight) and anemia was compared between indigenous and non-indigenous children. Probability ratios (PR) were used to compare prevalences in indigenous and non-indigenous children adjusting for socioeconomic status (SES) of the family and for other covariates. The prevalences of stunting and underweight were greater in indigenous than in non-indigenous children. At the national level and in urban areas the prevalences were three times greater and in rural areas approximately 2 times greater (p < 0.05). No differences were found in the prevalence of wasting (p > 0.05). The prevalence of anemia in indigenous children was one third greater than in non-indigenous children at the national level (p < 0.05) and was between 30 and 60% greater in urban areas and in the regions studied (p < 0.05) but was not statistically significant (p > 0.05) in rural areas. These differences were reduced to about half when adjusting for SES but remained significantly higher in indigenous children (p < 0.05). Indigenous children have higher probabilities of stunting and underweight than non-indigenous children. The differences are larger in urban areas and in higher socioeconomic geographic regions and are explained mostly by socioeconomic factors. The overall difference in the probability of anemia is small, is higher only in urban relative to rural areas, and is explained to a lesser degree by socioeconomic factors. Policy and programs should be designed and implemented to reduce the dramatic differences in nutritional status between indigenous and non-indigenous children in Mexico.

The severe life-threatening characteristics of hereditary angioedema (HAE) with C1-inhibitor deficiency (C1-INH-HAE) can affect anxiety levels among pediatric patients. This emotional burden together with the physical restrictions of C1-INH-HAE may decrease children's health-related quality of life (HRQoL). (i) To compare anxiety state and trait between children with C1-INH-HAE and healthy controls; (ii) to examine the relationship between the level of anxiety of children with C1-INH-HAE, their disease activity/affected sites and their HRQoL; and (iii) to predict the HRQoL of children with C1-INH-HAE based on their anxiety level and disease activity/affected sites METHODS: Thirty-three children with C1-INH-HAE (aged 5-18 years) and 52 healthy controls were recruited from Israel and Hungary. All children completed the State-Trait Anxiety Inventory for Children (STAIC), the Pediatric Quality of Life Inventory (Peds-QL) demographic questionnaire and a disease activity and site questionnaire . Disease activity was defined as the number of attacks in last year. Both anxiety state and trait were significantly higher among children with C1-INH-HAE as compared to the controls (44.74±10.56 vs 38.76±10.67, P<.01, 29.21±5.16 vs 25.23±4.09, P<.001 in comparison). Significant differences were found between C1-INH-HAE patients with HAE attacks, asymptomatic C1-INH-HAE patients, and healthy controls in both anxiety state (F 56,2 =4.69, P=.001) and trait (F 56,2 =9.06, P<.0001). A higher anxiety trait was correlated with the number of angioedema-affected sites (r=.52, P=.003). The presence of HAE attacks and higher anxiety trait predicted a lower HRQoL in children with C1-INH-HAE. C1-INH-HAE children have higher anxiety trait and state, which correlate with reduced HRQoL domains. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Using family systems theory as a theoretical framework, we investigated direct and indirect associations between type of disability, caregiver burden, and sibling relationships with structural equation modeling. We recruited 172 families raising typically developing children or a child with a disability. Participants volunteered at meetings and workshops for families of children with disabilities and were also recruited through snowball sampling. Mothers and fathers independently completed self-report questionnaires on caregiver burden and perceptions of the sibling relationship. Mothers experienced higher levels of caregiver burden than fathers. Parents of children with autism reported higher levels of caregiver burden than parents of typically developing children. Mothers of children with Down syndrome and multiple disabilities reported more positive sibling relationships than mothers of typically developing children. Mothers' and fathers' perceptions of caregiver burden were negatively related to their perceptions of the sibling relationship. Caregiver burden mediated the relationship between having a child with autism and positive sibling relationships. Results indicate the benefits of using a systems framework in examining families raising children with disabilities. Future research should focus on interventions for families of children with disabilities that help alleviate parental burden and foster positive sibling relationships.

In recent years, studies have shown that parents of children with Neurodevelopmental Disorders (NDDs) experience more parenting stress than parents of typically developing children, but the relation between the type of disorders and parenting stress is far from clear. The purpose of this study was to compare the parenting stress experienced by parents of 239 children with Specific Learning Disorders (SpLD), Language Disorders (LD), Autism Spectrum Disorder (ASD), Attention Deficit Hyperactivity Disorder (ADHD), and typical development (TD). Parents of children with NDDs experience more parenting stress than those of children who have TD. Although, parents of children with ASD or ADHD report the most high scores of parenting stress, also the parents of children with SpLD or LD report higher parental stress compared with parent of children without NDDs. Another interesting finding was that IQ level or emotional and behavioral problems are associated with the higher levels of parenting stress. This study suggest that parent, both mothers and fathers, of children with different type of NDDs should be provided with interventions and resources to empower them with the knowledge and skills to reduce their stress and to enhance their quality of life.

The definition of childhood metabolic syndrome has not been described clearly. Childhood obesity is increasing gradually, and the incidence of childhood metabolic syndrome is also rising. We aimed to show metabolic syndrome components and preventive factors for metabolic syndrome in obese children Methods: In the present study, 187 obese children and adolescents 5-18 years old were investigated retrospectively. Demographic data, anthropometric measurements, body mass index, blood pressure values, insulin levels, oral glucose tolerance test results, total cholesterol, high density lipoprotein, and triglyceride levels were obtained from hospital records. A body mass index > 95th percentile was considered obese. Insulin resistance was calculated according to the oral glucose tolerance test with 1.75 g/kg glucose maximum 75 g glucose. The insulin sensitivity index and homeostatic model assessment-insulin resistance (HOMA IR) were calculated and compared. Metabolic syndrome was diagnosed according to the modified WHO criteria adapted for metabolic syndrome in children. Abnormal glucose homeostasis was detected in 53% of subjects. Dyslipidaemia was present in 45.7% and hypertension in 16.6% of the patients. Metabolic syndrome was identified in 24.6% of obese children and adolescents. High HOMA-IR values and fasting glucose levels, elevated triglycerides and lower HDL levels were an indication of metabolic syndrome. Obesity and insulin resistance are significant factors for the development of metabolic syndrome in children and adolescents. In obese children higher HDL levels are preventive factor for metabolic syndrome. Preventing obesity and insulin resistance may decrease the prevalence of metabolic syndrome.

Hyperactivity in Attention-Deficit/Hyperactivity Disorder (ADHD): Impairing Deficit or Compensatory Behavior?

Excess gross motor activity (hyperactivity) is considered a core diagnostic feature of childhood ADHD that impedes learning. This view has been challenged, however, by recent models that conceptualize excess motor activity as a compensatory mechanism that facilitates neurocognitive functioning in children with ADHD. The current study investigated competing model predictions regarding activity level's relation with working memory (WM) performance and attention in boys aged 8-12 years (M = 9.64, SD = 1.26) with ADHD (n = 29) and typically developing children (TD; n = 23). Children's phonological WM and attentive behavior were objectively assessed during four counterbalanced WM tasks administered across four separate sessions. These data were then sequenced hierarchically based on behavioral observations of each child's gross motor activity during each task. Analysis of the relations among intra-individual changes in observed activity level, attention, and performance revealed that higher rates of activity level predicted significantly better, but not normalized WM performance for children with ADHD. Conversely, higher rates of activity level predicted somewhat lower WM performance for TD children. Variations in movement did not predict changes in attention for either group. At the individual level, children with ADHD and TD children were more likely to be classified as reliably Improved and Deteriorated, respectively, when comparing their WM performance at their highest versus lowest observed activity level. These findings appear most consistent with models ascribing a functional role to hyperactivity in ADHD, with implications for selecting behavioral treatment targets to avoid overcorrecting gross motor activity during academic tasks that rely on phonological WM.

The mechanisms involved in sequential immunoglobulin G (IgG) class switching are still largely unknown. Sequential IG class switching is linked to higher levels of somatic hypermutation (SHM) in vivo, but it remains unclear if these are generated temporally during an immune response or upon activation in a secondary response. We here aimed to uncouple these processes and to distinguish memory B cells from primary and secondary immune responses. SHM levels and IgG subclasses were studied with 454 pyrosequencing on blood mononuclear cells from young children and adults as models for primary and secondary immunological memory. Additional sequencing and detailed immunophenotyping with IgG subclass-specific antibodies was performed on purified IgG + memory B-cell subsets. In both children and adults, SHM levels were higher in transcripts involving more downstream-located IGHG genes (esp. IGHG2 and IGHG4). In adults, SHM levels were significantly higher than in children, and downstream IGHG genes were more frequently utilized. This was associated with increased frequencies of CD27 + IgG + memory B cells, which contained higher levels of SHM, more IGHG2 usage, and higher expression levels of activation markers than CD27 - IgG + memory B cells. We conclude that secondary immunological memory accumulates with age and these memory B cells express CD27, high levels of activation markers, and carry high SHM levels and frequent usage of IGHG2. These new insights contribute to our understanding of sequential IgG subclass switching and show a potential relevance of using serum IgG2 levels or numbers of IgG2-expressing B cells as markers for efficient generation of memory responses.

Low-income and some racial and ethnic subpopulations are more likely to suffer from obesity. Inequities in the physical and social environment may contribute to disparities in paediatric obesity, but there is little empirical evidence to date. This study explored whether neighbourhood-level socioeconomic factors attenuate racial and ethnic disparities in obesity among youth in the U.S.A. and whether individual-level socioeconomic status (SES) interacts with neighbourhood deprivation. This analysis used data from 17,100 youth ages 2-18 years participating in the 2001-2010 National Health and Nutrition Examination Survey linked to census tract-level socioeconomic characteristics. Multilevel logistic regression models were used to examine neighbourhood deprivation in association with odds of obesity (age-specific and sex-specific body mass index percentile ≥95). The unadjusted prevalence of obesity was 15% among non-Hispanic white children and 21% among non-Hispanic black and Mexican-American children. Adjustment for individual-level SES neighbourhood deprivation and the interaction between these two factors resulted in a 74% attenuation of the disparity in obesity between non-Hispanic black and non-Hispanic white children and a 49% attenuation of the disparity between Mexican-American and non-Hispanic white children. There was a significant interaction between individual-level SES and neighbourhood deprivation where higher individual-level income was protective for children living in low-deprivation neighbourhoods, but not for children who lived in high-deprivation areas. Conversely, area deprivation was associated with higher odds of obesity, but only among children who were above the poverty threshold. Future research on disparities in obesity and other health outcomes should examine broader contextual factors and social determinants of inequities.

The impact of early postnatal lead exposure measured at age 4 on children's IQ and academic achievement at and 11 years of age was examined. The sample consisted of 278 inner-city, primarily African American children who were polydrug exposed prenatally. Regression analyses indicated a linear effect of lead exposure on outcomes and no moderating effects of polydrug exposure. An IQ loss of about 4.1-5.4 Full Scale IQ points was estimated for each 10 microg/dL increase in blood lead level at ages 4, 9, and 11 years as a function of blood lead level at age 4. Decrements in scores on tests of non-verbal reasoning were consistently associated with higher lead levels at age 4, while verbal decrements became apparent only at age 11. Lower reading summary scores at 9 and 11 years were consistently associated with higher lead exposure, while decrements in mathematics were not apparent until 11 years. Subgroup analyses on children with blood lead levels <10 microg/dL showed detrimental lead effects even at the 5 microg/dL level, providing additional evidence of adverse effects occurring at blood lead levels below the current 10 microg/dL public health blood lead action level.

Human immunodeficiency virus (HIV) carries a high level of stigma to the HIV-infected individuals and their family members. Children of HIV-infected parents in China are particularly affected. The present study examined the relationship between associative stigma, self-esteem, optimism, anxiety and depression among 195 children of HIV-infected parents in rural China. Findings showed that more than one-third (35.4 %) of the participants scored higher than cut-off for depression; and 23.6-67.7 % of them scored higher than cut-off for different types of anxiety disorders. Structural equation modelling revealed that associative stigma had a significant negative relationship on self-esteem and optimism, which were associated with higher levels of depression and anxiety. The indirect effects of associative stigma on depression and anxiety were significant. The overall model showed a satisfactory fit. Findings suggest that associative stigma has a significant negative impact on mental health of children affected by HIV. Interventions to reduce their associative stigma are warranted.

Participants included 686 parent-child dyads from four major children's hospitals in the United States. Latino parents who grew up in the U.S. reported higher levels of anxiety (p = 0.009) and stress (p < 0.001) compared to parents who grew up in a Latin American country. Additionally, English-speaking Latino parents reported higher anxiety and stress compared to both Spanish-speaking Latino and non-Latino white parents (p's < 0.05), whereas Spanish-speaking Latino and non-Latino white parents reported similar levels of stress and anxiety. Results of the current study were consistent with the immigrant health paradox in that more acculturated Latino parents reported higher levels of anxiety and stress than less acculturated Latino and non-Latino white parents, supporting the need for culturally tailored interventions in the perioperative environment.

Objective Carboplatin is a common chemotherapy agent with potential ototoxic side effects that is used to treat a variety of pediatric cancers, including retinoblastoma. Retinoblastoma is a malignant tumor of the retina that is usually diagnosed in young children. Distortion-product otoacoustic emission tests offer an effective method of monitoring for ototoxicity in young children. This study was designed to compare measurements of distortion-product otoacoustic emissions obtained before and after several courses of carboplatin chemotherapy in order to examine if (a) mean distortion-product otoacoustic emission levels were significantly different; and (b) if criterion reductions in distortion-product otoacoustic emission levels were observed in individual children. Methods A prospective repeated measures study. Ten children with a median age of 7.6 months (range, 3–72 months) diagnosed with unilateral or bilateral retinoblastoma were examined. Distortion-product otoacoustic emissions were acquired from both ears of the children with 65/55 dB SPL primary tones (f2= 793–7996 Hz) and a frequency resolution of 3 points/octave. Distortion-product otoacoustic emission levels in dB SPL were measured before chemotherapy treatment (baseline measurement) and after 3–4 courses of chemotherapy (interim measurement). Comparisons were made between baseline and interim distortion-product otoacoustic emission levels (collapsed across ears). Evidence of ototoxicity was based on criterion reductions (≥ 6 dB) in distortion-product otoacoustic emission levels. Results Significant differences between baseline and interim mean distortion-product otoacoustic emission levels were only observed at f2=7996 Hz. Four children exhibited criterion reductions in distortion-product otoacoustic emission levels. Conclusions Mean distortion-product otoacoustic emission levels at most frequencies were not changed following 3–4 courses of carboplatin chemotherapy in children with retinoblastoma. However, on an individual basis, children receiving higher doses of carboplatin exhibited criterion reductions in distortion-product otoacoustic emission level at several frequencies. These findings suggest that higher doses of carboplatin affect outer hair cell function, and distortion-product otoacoustic emission tests can provide useful information when monitoring children at risk of developing carboplatin ototoxicity.

Food addiction research in children is limited, and to date addictive-like eating behaviors within families have not been investigated. The aim of this study is to understand factors associated with addictive-like eating in children. The association between food addiction in children with obesity, parental food addiction, and parental feeding practices (i.e., restriction, pressure to eat, monitoring) was investigated. Parents/primary caregivers (aged≥18years) of children aged 5-12years, recruited and completed an online cross-sectional survey including demographics, the Yale Food Addiction Scale (YFAS), and the Child Feeding Questionnaire (CFQ). Parents, reporting on themselves and one of their children, were given a food addiction diagnosis and symptom score according to the YFAS predefined criteria. The total sample consisted of 150 parents/primary caregivers (48% male) and 150 children (51% male). Food addiction was found to be 12.0% in parents and 22.7% in children. In children, food addiction was significantly associated with higher child BMI z-scores. Children with higher food addiction symptoms had parents with higher food addiction scores. Parents of FA children reported significantly higher levels of Restriction and Pressure to eat feeding practices, but not Monitoring. Children with elevated YFAS-C scores may be at greater risk for eating-related issues. Copyright © 2017 Elsevier Ltd. All rights reserved.

Background There is evidence that children with Attention Deficit Hyperactivity Disorder (ADHD) and Autistic Spectrum Disorder (ASD) have lower omega-3 polyunsaturated fatty acid (n-3 PUFA) levels compared with controls and conflicting evidence regarding omega-6 (n-6) PUFA levels. Objectives This study investigated whether erythrocyte n-3 PUFAs eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) were lower and n-6 PUFA arachidonic acid (AA) higher in children with ADHD, ASD and controls, and whether lower n-3 and higher n-6 PUFAs correlated with poorer scores on the Australian Twin Behaviour Rating Scale (ATBRS; ADHD symptoms) and Test of Variable Attention (TOVA) in children with ADHD, and Childhood Autism Rating Scale (CARS) in children with ASD. Methods Assessments and blood samples of 565 children aged 3–17 years with ADHD (n = 401), ASD (n = 85) or controls (n = 79) were analysed. One-way ANOVAs with Tukey’s post-hoc analysis investigated differences in PUFA levels between groups and Pearson’s correlations investigated correlations between PUFA levels and ATBRS, TOVA and CARS scores. Results Children with ADHD and ASD had lower DHA, EPA and AA, higher AA/EPA ratio and lower n-3/n-6 than controls (P<0.001 except AA between ADHD and controls: P = 0.047). Children with ASD had lower DHA, EPA and AA than children with ADHD (P<0.001 for all comparisons). ATBRS scores correlated negatively with EPA (r = -.294, P<0.001), DHA (r = -.424, P<0.001), n-3/n-6 (r = -.477, P<0.001) and positively with AA/EPA (r = .222, P <.01). TOVA scores correlated positively with DHA (r = .610, P<0.001), EPA (r = .418, P<0.001) AA (r = .199, P<0.001), and n-3/n-6 (r = .509, P<0.001) and negatively with AA/EPA (r = -.243, P<0.001). CARS scores correlated significantly with DHA (r = .328, P = 0.002), EPA (r = -.225, P = 0.038) and AA (r = .251, P = 0.021). Conclusions Children with ADHD and ASD had low levels of EPA, DHA and AA and high ratio of n-6/n-3 PUFAs and these correlated significantly with symptoms. Future research should further investigate abnormal fatty acid metabolism in these disorders. PMID:27232999

We examined the effects of a foster care intervention on attention and emotion expression in socially deprived children in Romanian institutions. Institutionalized children were randomized to enter foster care or to remain under institutional care. Subsequently, the institutionalized and foster care groups, along with a community-based comparison group, were evaluated on emotion tasks at 30 and 42 months of age. Behaviors reflecting positive and negative affect and attention were coded from videotapes. Data indicated that at both age points, children who received the foster care intervention showed higher levels of attention and positive affect compared to children who remained institutionalized. Compared to the community sample, children in the foster care intervention showed higher levels of attention to the emotion-eliciting tasks at 42 months of age. The results of this randomized trial demonstrate the impact of a family-based intervention on the development of attention and positive affect.

To examine the relationship of self-reported parental overprotection, perceived child vulnerability, and parenting stress to parent-reported behavioral, emotional, and social adjustment of children currently on treatment for cancer. Parents of 62 children (34 boys, 28 girls) currently on treatment for cancer were recruited from an outpatient pediatric cancer clinic. Children ranged in age from 2 to 12 years; age at diagnosis ranged from 1.33 to 11.83 years. Higher levels of parenting stress, but not parental overprotection or perceived child vulnerability, were associated with poorer behavioral and social adjustment. Higher levels of perceived child vulnerability and parenting stress, but not parental overprotection, were independently associated with poorer emotional adjustment. Specific parenting variables appear to be related to specific adjustment outcomes in children with cancer. Longitudinal follow-up of these children is necessary to determine the developmental trajectory of parent variables and long-term child outcomes.

Enjoyment has been implicated as a determinant of physical activity among children and adolescents. However, the effect of different sport activities on children's enjoyment remains largely unexplored. This study examined whether children's enjoyment in physical education (PE) varied as a function of learning activities. Participants were 210 third- through sixth-grade children who had a 30 min PE class every week. Participants responded to a standardized self-report enjoyment survey measuring their enjoyment level in a PE class during which they participated in tag games. Students completed the same questionnaire when involved in interactive dance games in PE. The results revealed that children reported significantly higher scores in enjoyment toward interactive dance games than they did toward traditional games (p < .01). Also, girls exhibited higher enjoyment toward interactive dance games than boys did (p < .05). However, no gender difference emerged on enjoyment toward traditional games. In conclusion, it is practical and meaningful to integrate interactive dance games into PE.

Most of the studies and interventions are targeted to address undernutrition, but childhood obesity has become a silent killer among children. Developing countries, including Turkey, could recognize the importance of the issue now and have begun to discuss the necessity of studies on this subject. Therefore, this study aims to examine the prevalence of obesity among pre-school children in Turkey. The data source of this study is the Turkey Demographic and Health Survey (TDHS)-2013. The TDHS-2013 was a sample study to gather information about the fertility levels and changes in them, infant and child mortality, family planning, and maternal and infant health at the national level. Overweight/obesity for height was 8.6% and 6.6% for age. Overweight/obesity problems are mostly observed in the West and are higher in urban areas. Overweight/obesity decreases with increasing age. There is a positive correlation between overweight/obesity and maternal educational level. As the household welfare level increases, overweight/obesity increases in pre-school children. Female children are at higher risk of overweight/obesity than males. As birth order increases, overweight/obesity decreases. Children living in other regions have overweight/obesity problems more than the pre-school children living in the East. This study speculates that obesity appears to be a major problem among pre-school children in Turkey. Based on the findings, the current situation of overweight/obesity among pre-school children is so close to many developing and developed countries, whose obesity levels are a greater concern. This finding demonstrates that effective interventions of obesity should begin as early as infancy in Turkey, as it is a developing country.

The prevalence of obesity is increasing. The aim of this study was to investigate if there is endothelial dysfunction in children with normal or excess weight, and whether the metabolic profile, adipokines, and endothelial dysfunction would be more strongly associated with physical fitness or with physical activity levels. Cross-sectional study involving children aged 5-12 years. The evaluation included venous occlusion plethysmography, serum levels of adiponectin, leptin and insulin, lipid profile, physical activity score (PAQ-C questionnaire), and physical fitness evaluation (Yo-Yo test). A total of 62 children participated in this study. Based on the body mass index, 27 were eutrophic, 10 overweight and 25 obese. Triglycerides, LDL cholesterol, HOMA-IR, and leptin were higher in the obese and excess-weight groups compared to the eutrophic group (p<0.01). HDL cholesterol and adiponectin levels were higher in the eutrophic group compared to the obese and excess-weight groups (p<0.01). Flow-mediated vasodilation after hyperemia was higher in the eutrophic group in comparison to obese and excess-weight subjects (p<0.05). There was no difference in the physical activity levels among groups measured by PAQ-C. The Yo-Yo test was significantly associated with HDL cholesterol (rho=-0.41; p=0.01), and this association remained after adjusting for body mass index z-score (rho=0.28; p=0.03). This study showed that endothelial dysfunction is already present in obese children, suggesting a predisposition to atherosclerotic disease. Moreover, HDL cholesterol levels were correlated with physical fitness, regardless of body mass index. Copyright © 2018. Published by Elsevier Editora Ltda.

Our study examined parenting stress and its association with behavioral problems and disease severity in children with problematic severe asthma. Research participants were 93 children (mean age 13.4 ± 2.7 years) and their parents (86 mothers, 59 fathers). As compared to reference groups analyzed in previous research, scores on the Parenting Stress Index in mothers and fathers of the children with problematic severe asthma were low. Higher parenting stress was associated with higher levels of internalizing and externalizing behavioral problems in children (Child Behavior Checklist). Higher parenting stress in mothers was also associated with higher airway inflammation (FeNO). Thus, although parenting stress was suggested to be low in this group, higher parenting stress, especially in the mother, is associated with more airway inflammation and greater child behavioral problems. This indicates the importance of focusing care in this group on all possible sources of problems, i.e., disease exacerbations and behavioral problems in the child as well as parenting stress.

The aim of the study was to examine predictors of eating disorder symptoms in a population based sample at the earliest age at which they can be measured using the Children's Eating Attitudes Test. Data were collected from the longitudinal Gateshead Millennium Study cohort; 609 children participated in the 7 year data sweep (and their mothers and teachers), and 589 children participated in the 9 year data sweep. Eating disorder symptoms at 9 years were higher in boys, and in children from more deprived families. Higher eating disorder symptoms were associated with more body dissatisfaction at 9 years. Higher symptoms were predicted by higher levels of dietary restraint and of emotional symptoms, but not greater body dissatisfaction, 2 years earlier. The study showed that some correlates of high eating disorder symptoms found in adolescents and adults are also found in children, before the rise in diagnosable eating disorders over the pubertal period.

Blood lead (PbB) and hemoglobin levels (Hb) were determined in 40 battery repair/recycling shop workers, 16 radiator repair shop workers, and 20 children living in the immediate vicinity of these shops. Unexposed residents with similar socioeconomic status were also investigated. Mean PbB level was significantly higher for battery workers (54.23 microg/dL) when compared to radiator workers (20.04 microg/dL) and unexposed adults (12.56 microg/dL) (P<0.001). Among battery workers, 94% had PbB levels above the WHO permissible exposure limit of 40 microg/dL for males and 30 microg/dL for females. There was no demarcation between workplace and living quarters; therefore, workers' families were similarly exposed to hazards. Children living in the immediate vicinity of battery shops also had significantly higher mean PbB levels (49.88 microg/dL) compared to radiator shop children (11.84 microg/dL) and unexposed children (9.92 microg/dL). For workers with PbB > 40 microg/dL, 90% were anemic (Hb < 13 g/dL for males and <11.5 g/dL for females). Linear regression showed a correlation (r=-0.214; P=0.03) between Hb level and log(10)PbB. There was no significant relationship between anemia and blood lead in children (r=-0.146). We conclude that radiator repair activities appeared to increase the body burden of lead, although not up to a level significantly different from unexposed counterparts. Battery recycling/repair activities, however, significantly increased blood lead levels in workers and their children. Copyright 2000 Academic Press.

The stepfamily literature is replete with between-group analyses by which youth residing in stepfamilies are compared to youth in other family structures across indicators of adjustment and well-being. Few longitudinal studies examine variation in stepfamily functioning to identify factors that promote the positive adjustment of stepchildren over time. Using a longitudinal sample of 191 stepchildren (56% female, mean age = 11.3 years), the current study examines the association between the relationship quality of three central stepfamily dyads (stepparent-child, parent-child, and stepcouple) and children's internalizing and externalizing problems concurrently and over time. Results from path analyses indicate that higher levels of parent-child affective quality are associated with lower levels of children's concurrent internalizing and externalizing problems at Wave 1. Higher levels of stepparent-child affective quality are associated with decreases in children's internalizing and externalizing problems at Wave 2 (6 months beyond baseline), even after controlling for children's internalizing and externalizing problems at Wave 1 and other covariates. The stepcouple relationship was not directly linked to youth outcomes. Our findings provide implications for future research and practice. © 2017 Family Process Institute.

Environmental moderation of the level of genetic influence on children's reading disabilities (RD) was explored in a sample of 545 identical and fraternal twins (mean age = 11.5 years). Parents' years of education, which are correlated with a broad range of environmental factors related to reading development, were significantly related to the level of genetic influence on reading disability (t = 3.23, Prep = .99). Genetic influence was higher and environmental influence was lower among children with higher compared to children with lower parent education. We discuss the implications of these results for behavior- and molecular-genetic research, for the diagnosis and remediation of RD, and for policy in public education. PMID:19076484

Peanut sensitization is common in children. However, it is difficult to assess which children will react mildly and which severely. This study evaluated the relevance of basophil allergen sensitivity testing to distinguish the severity of peanut allergy in children. Twenty-seven peanut-sensitized children with symptoms varying from mild symptoms to severe anaphylaxis underwent peanut CD63 dose-response curve analysis with the inclusion of basophil allergen sensitivity calculation (CD-sens) and peanut component immunoglobulin E (IgE) testing. Eleven children who had experienced anaphylaxis to peanuts showed a markedly higher peanut CD63 response at submaximal allergen concentrations and CD-sens (median 1,667 vs. 0.5; p < 0.0001) than 16 children who experienced a milder reaction. Furthermore, a negative or low CD-sens to peanuts unambiguously excluded anaphylactic peanut allergy. Children with anaphylaxis have higher levels of Ara h 1, 2, 3 and 9 IgE, but comparable levels of IgE to Ara h 8 and whole-peanut extract. The diagnostic specificity calculated with a receiver operating characteristic analysis reached 100% for CD-sens and 73% for Ara h 2. We demonstrated that severe peanut allergy is significantly associated with higher basophil allergen sensitivity. This cellular test should facilitate a more accurate diagnosis of peanut allergy. © 2013 S. Karger AG, Basel.

Multiple factors are involved in the occurrence of aggressive behavior. The purpose of this study was to evaluate the hypotheses that Latino middle school children exposed to higher levels of video game playing will exhibit a higher level of aggression and fighting compared to children exposed to lower levels and that the more acculturated middle school Latino children will play more video games and will prefer more violent video games compared to less acculturated middle school Latino children. This study involved 5,831 students attending eight public schools in Texas. A linear relationship was observed between the time spent playing video games and aggression scores. Higher aggression scores were significantly associated with heavier video playing for boys and girls (p < 0.0001). The more students played video games, the more they fought at school (p < 0.0001). As Latino middle school students were more acculturated, their preference for violent video game playing increased, as well as the amount of time they played video games. Students who reported speaking more Spanish at home and with their friends were less likely to spend large amounts of time playing video games and less likely to prefer violent video games (p < 0.05).

There is an increasing attempt in the world to determine the exposures of children to environmental chemicals. To analyze the genotoxic effect of air pollution, micronucleus (MN) assay was carried out in buccal epithelial cells (BECs) of children living in an urban city of Turkey. Children from two schools at urban-traffic and suburban sites were investigated in summer and winter seasons for the determination of BEC-MN frequency (per mille) and frequency of BEC with MN (per mille). The same children were also recruited for lung function measurements within a MATRA project ("Together Towards Clean Air in Eskisehir and Iskenderun") Measured NO2 and SO2 concentrations did not exceed the European Union (EU) limit levels either in urban-traffic or suburban regions. Higher O3 concentrations were measured in the suburban site especially in the summer period. Particulate matter (PM2.5 and PM10) levels which did not differ statistically between two regions were above the EU limits in general. Although BEC-MN frequencies of children living in the suburban sites were higher in general, the difference between two regions was not significant either in the summer or winter periods. BEC-MN frequencies of the urban-traffic children were found to be significantly higher in summer period (mean ± SD, 2.68 ± 1.99) when compared to winter period (1.64 ± 1.59; p = 0.004). On the other hand, no seasonality was observed for the suburban children. Similar results have been obtained in the BEC frequency with MN in our study. In summer, BEC-MN frequencies were significantly increased with the decrease in pulmonary function levels based on forced expiratory flow between 25 and 75% of vital capacity (FEF25-75%) levels (p < 0.05). As a conclusion, children living in urban-traffic and suburban areas in the city of Eskişehir exhibited similar genotoxicity. Seasonal variation in genotoxicity may be interpreted as relatively high ozone levels and increasing time spent at outdoors in the summer.

The back-to-school stress survey was an international, non-clinical opinion survey, which aimed to compare stress levels in parents of children with/without attention deficit hyperactivity disorder (ADHD) during the back-to-school period. Here, we present results relating to the Italian sample, comparing them with European data. The questionnaire was built using a modified Holmes and Rahe stress scale. Parents of children with/without ADHD evaluated potentially stress-causing situations on a scale from 1 (low stress) to 10 (high stress). In Italy, 107 parents of children with ADHD (mean age ± SD 40.3±7.3 years) and 105 parents of children without ADHD (mean age 42.2±6.6 years) participated in the survey. The mean age of children with ADHD was 10.3±3.1 years; 77.6% were male, 72.9% had been diagnosed with at least one comorbid condition - in particular conduct disorder (24.3%), learning disorders/dyslexia (23.4%) and language/communication disorder (19.6%) - and 32.7% were receiving ADHD medication. Parents of children with ADHD showed significantly higher stress levels (p≤0.005) compared with the non-ADHD group in all areas analyzed that were related to the return to school. Significant differences between groups (P<0.05) were also observed in most standard areas evaluated (e.g. personal life). These results were in agreement with data obtained for the overall European sample. Parents of children with ADHD suffer significantly higher stress levels compared with parents of children without ADHD. Considering parental stress is important for the management of children with ADHD, as stress can affect the control of behavioral symptoms of children.

Omega-3 long chain-polyunsaturated fatty acids (LC-PUFAs)-docosahexaenoic acid (DHA), docosapentaenoic acid (DPA) and eicosapentaenoic acid (EPA)- and omega-6 LC-PUFA arachidonic acid (ARA), are essential for optimum physical and mental development in children. Prior to this study, the blood omega-3 LC-PUFA levels were unknown in Zimbabwean children, particularly in those aged 7-9 years, despite the documented benefits of LC-PUFAs. Documentation of the LC-PUFA levels in this age group would help determine whether interventions, such as fortification, are necessary. This study aimed to determine dried whole blood spot omega-3 and omega-6 LC-PUFA levels and LC-PUFA reference intervals among a selected group of Zimbabwean children aged 7-9 years old. We conducted a cross sectional study from September 2011 to August 2012 on a cohort of peri-urban, Zimbabwean children aged 7-9 years. The children were born to mothers enrolled at late pregnancy into an HIV prevention program between 2002 and 2004. Dried whole blood spots were sampled on butylated hydroxytoluene antioxidant impregnated filter papers and dried. LC-PUFAs were quantified using gas liquid chromatography. Differences in LC-PUFAs between groups were compared using the Kruskal Wallis test and reference intervals determined using non-parametric statistical methods. LC-PUFAs levels were determined in 297 Zimbabwean children of whom 170 (57.2 %) were girls. The study determined that LC-PUFAs (wt/wt) ranges were EPA 0.06-0.55 %, DPA 0.38-1.98 %, DHA 1.13-3.52 %, ARA 5.58-14.64 % and ARA: EPA ratio 15.47-1633.33. Sixteen participants had omega-3 LC-PUFAs levels below the determined reference intervals, while 18 had higher omega-6 LC-PUFAs. The study did not show gender differences in omega-3 and omega-6 LC-PUFAs levels (all p > 0.05). EPA was significantly higher in the 8 year age group compared to those aged 7 and 9 years (median; 0.20 vs 0.17 vs 0.18, respectively, p = 0.049). ARA: EPA ratio was significantly higher in the 7 year age group compared to those aged 8 and 9 years (median; 64.38 vs 56.43 vs 55.87 respectively, p = 0.014). In this cohort of children, lower EPA levels and higher ARA: EPA ratios were observed compared to those reported in apparently healthy children elsewhere. The high ARA: EPA ratios might increase the vulnerability of these children to inflammatory pathologies. Identification and incorporation into diet of locally produced foodstuffs rich in omega-3 LC-PUFAs is recommended as well as advocating for dietary supplementation with omega-3 fish oils and algae based oils.

Parents with children with developmental disabilities (DD) encounter a variety of stressors associated with rearing their children and must develop effective coping mechanisms in order to adapt successfully to these challenges. Previous research has failed to establish the role of parental individual differences in the reported use of different coping strategies. The current study explores parental personality and whether children with DD were adopted or born into the families and their influence on the coping strategies used by mothers and fathers. A total of 97 mother-father dyads rearing at least one child with DD were participants. They narrated stressful situations related to their child and completed the Ways of Coping Questionnaire twice. Data were also collected with regard to personality, depression and subjective well-being (SWB). Both adoptive and birth mothers and fathers used more problem-focused than emotion-focused strategies. Personality factors, Neuroticism especially, were predictive of coping strategy use. Higher levels of Positive Reappraisal were associated with higher levels of SWB, whereas higher levels of Escape-Avoidance were associated with lower levels of SWB, but only for mothers. Results were consistent with a dispositional model of strategy use in that frequency of use was associated with personality characteristics, was consistent over time, and for different children in the same families. Future research should focus on the persistence of the associations between strategy use and well-being and whether they hold true at different stages of the lifespan when coping contexts may change quite dramatically.

Neopterin, a pteridine mainly synthesized by activated macrophages, is a marker of inflammation, immune system activation and an active participant in Autism spectrum disorders (ASD). The aim of this study was to assess the clinical significance of plasma neopterin levels in ASD. Eighty patients diagnosed with ASD and 80 sex and age matched typically developing children were assessed for plasma levels of neopterin at admission. Plasma neopterin levels were measured using a human ELISA kit and severity of ASD were evaluated with the Childhood Autism Rating Scale (CARS) score. We found that the mean plasma neopterin level was significantly (P<0.0001) higher in children with ASD as compared to controls. Plasma neopterin increased with increasing severity of ASD as defined by the CARS score. Based on the ROC curve, the optimal cutoff value of plasma neopterin level as an indicator for auxiliary diagnosis of ASD was projected to be 8.5nmol/L, which yielded a sensitivity of 84.2% and a specificity of 80.1%, with the area under the curve at 0.876 (95% CI, 0.825-0.928). Elevated neopterin (≥8.5nmol/L) was an independent diagnosis indicator of ASD with an adjusted OR of 12.11 (95% CI: 5.48-28.11; P<0.0001). These results indicated that autistic children had higher plasma levels of neopterin, and elevated plasma neopterin levels may be associated with severity of ASD among Chinese children.

The diagnosis of meningitis was based on clinical features and cerebrospinal fluid findings. PCT levels were measured with a specific immunoluminometric assay. (a) Patients with bacterial meningitis had significantly higher serum PCT than those with viral meningitis. (b) The PCT levels of patients with severe sepsis or septic shock were significantly higher than those who had no or mild sepsis. (c) PCT levels decreased significantly in patients who had good curative effect, whereas PCT levels did not changed in patients who had no curative effect. (d) The PCT levels were significantly higher in those who died than those who survived. Serum PCT is related to the severity of disease in children with bacterial meningitis. A fall in PCT after treatment may have favorable prognostic significance. © The Author(s) 2015.

Objective: To determine the association, if any, between thyroid-stimulating hormone (TSH) levels and body mass index (BMI) percentiles in children with primary hypothyroidism who are chemically euthyroid and on treatment with levothyroxine. Methods: This retrospective cross-sectional study consisted of a review of medical records from RUSH Medical Center and Stroger Hospital, Chicago, USA of children with primary hypothyroidism who were seen in the clinic from 2008 to 2014 and who were chemically euthyroid and on treatment with levothyroxine for at least 6 months. The patients were divided into two groups based on their TSH levels (0.34-<2.5 mIU/L and ≥2.5-5.6 mIU/L). The data were analyzed by Spearman rank correlation, linear regression, cross tabulation and chi-square, Mann-Whitney U test, and Kruskal-Wallis test. Results: One hundred and forty-six children were included, of which 26% were obese (BMI ≥95%), 21.9% overweight (BMI ≥85-<95%), and 52.1% of a healthy weight (BMI ≥5-<85%). There was a significant positive correlation between TSH and BMI percentiles (r=0.274, p=0.001) and a significant negative correlation between TSH and serum free T4 (r=-0.259, p=0.002). In the lower TSH group, 68.4% of the children had a healthy weight, while the percentage of obese children was 60.5% in the upper TSH group (p=0.012). Conclusion: In children diagnosed with primary hypothyroidism who are chemically euthyroid on treatment with levothyroxine, there is a positive association between higher TSH levels and higher BMI percentiles. However, it is difficult to establish if the higher TSH levels are a direct cause or a consequence of the obesity. Further studies are needed to establish causation beyond significant association.

Despite a significant civilization advancement, parasitic diseases still pose a serious diagnostic and therapeutic problem. Children's susceptibility to these infections stems from their immature immune system and lack of basic hygiene routines. The objective of the study was to evaluate the level of knowledge which parents of preschool children's possess about parasitic diseases in their children's environment. The study was carried out in the group of 151 parents of preschool children living both in the city and in the country. The survey was carried out by means of a diagnostic poll with the application of a self-designed research questionnaire. To make the evaluation even more objective, a special scale was created in which parents could score points for their answers (0 - wrong answer, 1 - correct answer). The total number of points ranging from 0 to 9 indicated an unsatisfactory level of knowledge, from 10 to 13 - satisfactory level, from 14 to 16 - good level and from 17 to 20 - very good level of parents' awareness. The results of the study reveal that the level of parents' knowledge about parasitic diseases is only satisfactory. A statistically significant relationship was observed between the variables such as education and sex. The higher education, the higher level of knowledge. Moreover, women were more knowledgeable in the field of parasitic diseases than men were. Financial status of the family did not influence the level of parents' awareness. Well-planned educational programmes might have a positive influence on developing proper hygiene routines in families, which, in turn, will limit the risk of spreading parasitoses in the population of children.

The inner-city pediatric population in the United States has a disproportionate burden of asthma. Recent attention has focused on the immunomodulatory role of vitamin D, which may be protective against disease morbidity. As the primary determinant of vitamin D status in humans is exposure to sunlight, we aimed to determine if 25-OH vitamin D levels in urban preschool children with asthma were low, influenced by time spent outdoors, and associated with asthma morbidity. Serum 25-OH vitamin D levels were measured at baseline in a cohort of 121 inner-city children ages 2-6 years with asthma in Baltimore, MD. Participants were followed longitudinally at 3 and 6 months to assess time spent outdoors, asthma symptoms through questionnaires and daily diaries, and allergic markers. In a predominantly black population of preschool children, the median 25-OH vitamin D level was 28 ng/mL (IQR 21.2-36.9), with 54% of the children below the traditionally sufficient level of 30 ng/mL and 7.4% in the range associated with risk of rickets (< 15 ng/mL). The median time spent outdoors was 3 hours/day (IQR 2-4), and greater time spent outdoors was not associated with higher vitamin D levels. 25-OH vitamin D did not show seasonal variation in our cohort (p = 0.66). Lower 25-OH levels were correlated with higher IgE levels. Urban African-American preschool children with asthma have high rates of vitamin D insufficiency, and increased outdoor exposure is unlikely to correct these low 25-OH vitamin D levels. Repletion in this population may require dietary supplementation.

Background/aim: Nesfatin-1, an anorexigenic molecule, seems to play a role in appetite regulation and energy homeostasis. The goal of this study was to evaluate the relation of nesfatin-1 with anthropometric and metabolic (ghrelin, leptin) parameters in children with idiopathic chronic malnutrition. Materials and methods: The study included 37 underweight and 38 healthy children who were similar regarding age, sex, and pubertal status. Anthropometric and biochemical (nesfatin-1, ghrelin, and leptin levels) variables were assessed. Results: A total of 37 underweight subjects (mean age 10.5 ± 2.6 years) and 38 heathy subjects (mean age 10.3 ± 2.3 years) were recruited. Underweight children had significantly higher nesfatin-1 (2.76 ± 0.4 vs. 1.56 ± 0.7, P < 0.001) and lower leptin levels (2.21 ± 2.0 vs. 5.21 ± 2.4, P < 0.001) than those of the control subjects. Nesfatin-1 levels were significantly associated with only leptin levels, after adjusting for age and BMI (r = –0.371, P = 0.001). Conclusion: The present study is the first to evaluate nesfatin-1 levels in relation with anthropometric and metabolic parameters in children with chronic malnutrition, who were subsequently found to have significantly higher nesfatin-1 levels. Our study underlines that nesfatin-1 may play a role in the development of malnutrition by inhibiting food intake in children.

The etiological factors involved in the etiology of autism remain elusive and controversial, but both genetic and environmental factors have been implicated. The aim of this study was to assess the levels and possible environmental risk factors and sources of exposure to mercury, lead, and aluminum in children with autism spectrum disorder (ASD) as compared to their matched controls. One hundred ASD children were studied in comparison to 100 controls. All participants were subjected to clinical evaluation and measurement of mercury, lead, and aluminum through hair analysis which reflects past exposure. The mean Levels of mercury, lead, and aluminum in hair of the autistic patients were significantly higher than controls. Mercury, lead, and aluminum levels were positively correlated with maternal fish consumptions, living nearby gasoline stations, and the usage of aluminum pans, respectively. Levels of mercury, lead, and aluminum in the hair of autistic children are higher than controls. Environmental exposure to these toxic heavy metals, at key times in development, may play a causal role in autism.

Autism spectrum disorder (ASD) is a complex neurodevelopmental disorder that affects social, communication, and behavioral development. Recent evidence supported but also questioned the hypothetical role of compounds containing mercury (Hg) as contributors to the development of ASD. Specific alterations in the urinary excretion of porphyrin-containing ring catabolites have been associated with exposure to Hg in ASD patients. In the present study, the level of urinary porphyrins, as biomarkers of Hg toxicity in children with ASD, was evaluated, and its correlation with severity of the autistic behavior further explored. A total of 100 children was enrolled in the present study. They were classified into three groups: children with ASD (40), healthy controls (40), and healthy siblings of the ASD children (20). Children with ASD were diagnosed using DSM-IV-TR, ADI-R, and CARS tests. Urinary porphyrins were evaluated within the three groups using high-performance liquid chromatography (HPLC), after plasma evaluation of mercury (Hg) and lead (Pb) in the same groups. Results showed that children with ASD had significantly higher levels of Hg, Pb, and the porphyrins pentacarboxyporphyrin, coproporphyrin, precoproporphyrin, uroporphyrins, and hexacarboxyporphyrin compared to healthy controls and healthy siblings of the ASD children. However, there was no significant statistical difference in the level of heptacarboxyporphyrin among the three groups, while a significant positive correlation between the levels of coproporphyrin and precoproporphyrin and autism severity was observed. Mothers of ASD children showed a higher percentage of dental amalgam restorations compared to the mothers of healthy controls suggesting that high Hg levels in children with ASD may relate to the increased exposure to Hg from maternal dental amalgam during pregnancy and lactation. The results showed that the ASD children in the present study had increased blood Hg and Pb levels compared with healthy control children indicating that disordered porphyrin metabolism might interfere with the pathology associated with the autistic neurologic phenotype. The present study indicates that coproporphyrin and precoproporhyrin may be utilized as possible biomarkers for heavy metal exposure and autism severity in children with ASD.

Purpose We investigated 1) the impact of differences in intelligence quotient discrepancy (IQD) on motor skills of preschool-aged children with autism spectrum disorders (ASD); 2) the relationships between IQD and motor skills in preschool-aged children with ASD. Methods A total of 127 ASD preschool-aged children were divided into three groups according to the size of the IQD: IQD within 1 standard deviation (1SD; EVENIQ; n=81), discrepantly higher verbal intelligence quotient (VIQ; n=22; VIQ>performance intelligence quotient [PIQ] above 1SD [≥15 points]), and discrepantly higher PIQ (n=24; PIQ>VIQ above 1SD [≥15 points]). Children’s IQD and motor skills were determined with the Wechsler Preschool and Primary Scale of Intelligence™ – Fourth Edition and the motor subtests of the Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT), respectively. Results One-way analysis of variance revealed significant group differences for the fine motor domain of the CDIIT and the visual–motor coordination subtest (F=3.37–4.38, p<0.05). Children with discrepantly higher PIQ were associated with better fine motor skills than were children with even IQD and those with discrepantly higher VIQ, and vice versa. IQD (PIQ – VIQ) had significant positive correlations with the fine motor domain and fine motor subtests of the CDIIT (r=0.18–0.29, p<0.05). Conclusion The IQD can identify different levels of fine motor skills in preschool-aged children with ASD. This study suggests important implications for clinicians, therapists, and researchers: discrepantly higher PIQ could be related to better visual–motor coordination, and discrepantly higher VIQ could be related to poor visual–motor coordination. Furthermore, the results support that when therapists are working with preschool-aged children with ASD who are developing fine motor skills or undertaking fine motor tasks related to visual–motor coordination, they may need to pay attention to the children’s IQD.

This retrospective study aimed to determine the prevalence of abnormal metabolic parameters in obese children and its correlation to the degree of obesity determined by body mass index (BMI). In total, 101 children seen at the Pediatric Gastroenterology Obesity Clinic at Stony Brook Children's University Hospital were enrolled in the study. The degree of obesity was characterized according to the following formula: (patient's BMI/BMI at 95th percentile) × 100%, with class I obesity >100%-120%, class II obesity >120%-140%, and class III obesity >140%. A set of metabolic parameters was evaluated in these patients. Frequency distributions of all study variables were examined using the χ(2) test of independence. Mean differences among the obesity classes and continuous measures were examined using 1-way analysis of variance. Within our study population, we found that 80% of our obese children had a low high-density lipoprotein (HDL) cholesterol level, 58% had elevated fasting insulin levels, and 32% had an elevated alanine aminotransferase (ALT) level. Class II obese children had a 2-fold higher ALT value when compared with class I children (P = .036). Fasting insulin, ALT, HDL cholesterol, and triglyceride levels trended with class of obesity. Obese children in classes II and III are at higher risk for developing abnormal laboratory values. We recommend obese children be further classified to reflect the severity of the obesity since this has predictive significance for comorbidities. Obesity classes I, II, and III could help serve as a screening tool to help communicate risk assessment. © 2013 American Society for Parenteral and Enteral Nutrition.

The aim of this study was to compare total IgA in the whole saliva of children with Down syndrome with levels in sibling and parent groups. IgA measurements were presented as the concentration in saliva (μg/ml) and also adjusted for salivary flow rate (SFR; μg/min). Twenty children with Down syndrome, ten siblings and twenty parents were recruited. Stimulated whole saliva was collected from the participants and SFR calculated. The measurement of salivary IgA (sIgA) was carried out using an indirect competitive Enzyme-Linked Immunosorbent Assay. The difference in the mean SFR between children with Down syndrome, parents and siblings were not statistically significant. The mean salivary concentration of IgA was higher in children with Down syndrome (95.1 μg/ml) compared with siblings (48.3 μg/ml; p=0.004). When adjusted for SFR children with Down syndrome had mean sIgA levels of 98.8 μg/min and the siblings 48.6 μg/min (p=0.008). The children with Down syndrome had sIgA levels similar to those of the parents (92.5 μg/ml; 93.2 μg/min). There was a positive correlation between age and sIgA concentration in the siblings (p=0.008) but not for children with Down syndrome (p=0.363). This suggests that under similar environmental influences, the levels of sIgA in children with Down syndrome are higher than in the siblings, from a very young age. Copyright © 2016 Elsevier Ltd.

2008-01-01

The current investigation addresses the manner through which trauma affects basic memory and self-system processes. True and false recall for self-referent stimuli were assessed in conjunction with dissociative symptomatology among abused (N=76), neglected (N=92), and nonmaltreated (N=116) school-aged children. Abused, neglected, and nonmaltreated children did not differ in the level of processing self-schema effect or in the occurrence and frequency of false recall. Rather, differences in the affective valence of false recall emerged as a function of maltreatment subtype and age. Regarding dissociation, the abused children displayed higher levels of dissociative symptomatology than did the nonmaltreated children. Although abused, neglected, and nonmaltreated children did not exhibit differences in the valence of their self-schemas, positive and negative self-schemas were related to self-integration differently among the subgroups of maltreatment. Negative self-schemas were associated with increased dissociation among the abused children, whereas positive self-schemas were related to increased dissociation for the neglected children. Thus, positive self-schemas displayed by the younger neglected children were related to higher dissociation, suggestive of defensive self-processing. Implications for clinical intervention are underscored.

2017-01-01

Abstract Deaf and hard of hearing school-aged children are at risk for delayed development of emotion understanding; however, little is known about this during the preschool years. We compared the level of emotion understanding in a group of 35 4–5-year-old children who use hearing aids to that of 130 children with typical hearing. Moreover, we investigated the parents’ perception of their child's level of emotion understanding. Children were assessed with the Test of Emotion Comprehension. Parents were presented with the same test and asked to guess what their child answered on each item. The results showed that children with hearing loss performed at the same level as typically hearing children, despite having lower vocabulary scores. Parents of children with hearing loss were more accurate in their estimations of their child's competence, and higher accuracy was associated with better emotion understanding. These findings may have implications for early intervention planning. PMID:27881481

Little attention has been focused on stress levels of parents of children with cochlear implants (CIs). This study examined the stress experience of 70 parents of children with CIs by comparing stress levels in this group of parents to those in parents of children without disabilities, identifying primary stressors, examining the relationship between parent stress and child language, and comparing stress in parents of children with bilateral and unilateral CIs. Parents completed a parent stress questionnaire, and the receptive vocabulary and language abilities of the children were evaluated. Results indicated that these parents had a higher incidence of stress than the normative population. Parent stress levels and child language outcomes were negatively correlated. Child behavior and lack of spousal and social support were the prime causes of parent stress. Parents of children with bilateral CIs were significantly less stressed than were parents of children with unilateral CIs.

The aim was to investigate which individual and family environmental factors are related to television and computer time separately in 10- to-12-year-old children within and across five European countries (Belgium, Germany, Greece, Hungary, Norway). Data were used from the ENERGY-project. Children and one of their parents completed a questionnaire, including questions on screen time behaviours and related individual and family environmental factors. Family environmental factors included social, political, economic and physical environmental factors. Complete data were obtained from 2022 child-parent dyads (53.8 % girls, mean child age 11.2 ± 0.8 years; mean parental age 40.5 ± 5.1 years). To examine the association between individual and family environmental factors (i.e. independent variables) and television/computer time (i.e. dependent variables) in each country, multilevel regression analyses were performed using MLwiN 2.22, adjusting for children's sex and age. In all countries, children reported more television and/or computer time, if children and their parents thought that the maximum recommended level for watching television and/or using the computer was higher and if children had a higher preference for television watching and/or computer use and a lower self-efficacy to control television watching and/or computer use. Most physical and economic environmental variables were not significantly associated with television or computer time. Slightly more individual factors were related to children's computer time and more parental social environmental factors to children's television time. We also found different correlates across countries: parental co-participation in television watching was significantly positively associated with children's television time in all countries, except for Greece. A higher level of parental television and computer time was only associated with a higher level of children's television and computer time in Hungary. Having rules regarding children's television time was related to less television time in all countries, except for Belgium and Norway. Most evidence was found for an association between screen time and individual and parental social environmental factors, which means that future interventions aiming to reduce screen time should focus on children's individual beliefs and habits as well parental social factors. As we identified some different correlates for television and computer time and across countries, cross-European interventions could make small adaptations per specific screen time activity and lay different emphases per country.

Observation that children`s fingerprints disappear from surfaces more quickly than adults`, initiated a study to characterize the chemical components in fingerprints. Samples were obtained from about 50 individuals ranging in age from 3 to 64 by extracting chemicals from the fingertips using rubbing alcohol. Using combined gas chromatography/mass spectrometry, a wide range of compounds were identified. Samples from children contained higher levels of relatively volatile free fatty acids, while those from adults had higher levels of less volatile long chain esters of fatty acids. These esters are thought to originate from sebaceous glands located on the face and levels ofmore » these compounds increase substantially after puberty. Also, other compounds were observed that could be used to develop improved methods for fingerprint detection at a crime scene. Further, observation of specific compounds raises the possibility of being able to identify personal traits (gender, habits, diseases, etc. ) via analysis of components in fingerprints and/or skin.« less

The purpose of this study was to examine the effects of parental stress, social support, and coping behavior on burnout among mothers caring for children with cerebral palsy. Participants in this cross-sectional, descriptive study were 185 mothers who completed a self-report structured questionnaire. The data were analyzed using descriptive statistics, t-test, one-way ANOVA, correlation and multiple linear regression analyses with IBM SPSS Win 22 program. Parental stress and coping behavior were strong predictors of burnout among mothers of children with cerebral palsy. These variables explained 50.0% of the variance in burnout. Social support was not a predictor of burnout. A higher level of burnout was associated with higher levels of parental stress and lower levels of social support and coping behavior. Mothers of children with cerebral palsy are vulnerable to burnout. These results show that effective strategies for reducing parental stress and improving positive coping behavior are needed to reduce burnout in these mothers. © 2017 Korean Society of Nursing Science

They boys and girls were from four different ethnic groups and attended grades one through 10 in 29 Southern California schools. The analysis of the data failed to show significant differences in mean blood pressure levels between the two groups of children at all ages, despite marked differences in life-style between the two groups, and despite the fact that adults from the two population groups have marked differences in mortality from diseases associated with elevated blood pressure. A comparison between boys and girls showed significantly higher trends in mean systolic blood pressure for boys after age 12. Inter-ethnic comparisons of blood pressure revealed that Black children of both sexes had slightly higher mean blood pressure levels at all ages.

It is important to monitor health differentials between population groups to understand how they are generated. Internationally displaced people represent one potentially disadvantaged group. We investigated differentials in mortality between children from former Mozambican refugee and host South African households in a rural sub-district in the north-east of South Africa. Open prospective cohort of 30 276 children (80 462 person years of follow-up) followed from 1 January 1992 to 31 October 2000 in Limpopo Province, South Africa. Exposure and outcomes data came from the Agincourt Health and Demographic Surveillance System (DSS). There was no difference in infant mortality between children from former Mozambican refugee households and those from South African homes (adjusted rate ratio [RR] = 1.02, 95% CI: 0.79, 1.32), but mortality levels were higher among former Mozambican refugee children during the next 4 years (adjusted RR = 1.91, 95% CI: 1.50, 2.42). Increased mortality levels were also seen among children from larger households and whose mother died, while children born to mothers aged >40 years or with higher education were at lower risk. Measured maternal, household, and health service utilization characteristics could not explain the difference in mortality between children from former Mozambican refugee and South African households. Former Mozambican refugee children residing in refugee settlements had higher mortality rates than those residing in more established villages. This study demonstrates higher childhood, but not infant, mortality rates among children from former Mozambican refugee households compared with those from host South African households in rural South Africa. The lack of legal status and lower wealth of many former Mozambican refugees may partly explain this disparity.

To identify the nutritional and immunological correlates of memory and neurocognitive development as measured by the Mullen Scales of Early Learning (MSEL) and by the Color Object Association Test (COAT) among children in Uganda. This analysis uses baseline data collected between 2008 and 2010 from 119 HIV-infected children aged 1-6 years, participating in a randomized controlled trial of an interventional parenting program in Kayunga, Uganda. Peripheral blood draws were performed to determine immunological biomarkers. Unadjusted and adjusted linear regression models were used to relate MSEL and COAT scores to sociodemographic characteristics, weight-for-age Z scores (WAZs), antiretroviral therapy status, and immunological biomarkers. In the final analysis, 111 children were included. Lower levels of CD4 CD38 T cells (P = 0.04) were associated to higher immediate and total recall scores (P = 0.04). Higher levels of CD8 HLA-DR T cells were associated with higher total recall score (P = 0.04) of the COAT. Higher CD4 CD38 HLA-DR T cells levels were associated with higher gross motor scores of the MSEL (P = 0.02). WAZ was positively correlated to visual reception, fine motor, expressive language, and composite score of the MSEL. Overall, WAZ was a stronger predictor of neurocognitive outcomes assessed by the MSEL. CD4 CD38 T cells were more specifically associated with memory-related outcomes. Future research should include immunological markers and standardized neurocognitive tests to further understand this relationship.

Exposure to intimate partner violence (IPV) has negative consequences for children's well-being and behavior. Much of the research on parenting in the context of IPV has focused on whether and how IPV victimization may negatively shape maternal parenting, and how parenting may in turn negatively influence child behavior, resulting in a deficit model of mothering in the context of IPV. However, extant research has yet to untangle the interrelationships among the constructs and test whether the negative effects of IPV on child behavior are indeed attributable to IPV affecting mothers' parenting. The current study employed path analysis to examine the relationships among IPV, mothers' parenting practices, and their children's externalizing behaviors over three waves of data collection among a sample of 160 women with physically abusive partners. Findings indicate that women who reported higher levels of IPV also reported higher levels of behavior problems in their children at the next time point. When parenting practices were examined individually as mediators of the relationship between IPV and child behavior over time, one type of parenting was significant, such that higher IPV led to higher authoritative parenting and lower child behavior problems [corrected]. On the other hand, there was no evidence that higher levels of IPV contributed to more child behavior problems due to maternal parenting. Instead, IPV had a significant cumulative indirect effect on child behavior via the stability of both IPV and behavior over time. Implications for promoting women's and children's well-being in the context of IPV are discussed.

Tinfoil manufacturing and electronic waste (e-waste) recycling remain rudimentary processes in Zhejing Province, China, which could account for elevated blood lead levels (BLLs) and health impacts on children. We assessed the potential health risks of lead in tinfoil manufacturing and e-waste recycling areas. 329 children in total aged 11-12 who lived in a tinfoil manufacturing area (Lanxi), an e-waste recycling area (Luqiao) and a reference area (Chun'an) were studied. Lead levels in children's blood were determined by inductively coupled plasma mass spectrometer (ICP-MS). Blood urea nitrogen (BUN), serum creatinine, serum calcium, δ-Aminolaevulinic acid (δ-ALA) and intelligence quotient (IQ) were also measured. Geometric mean of BLLs in Lanxi, Luqiao and Chun'an were 8.11 μg/dL, 6.97 μg/dL, and 2.78 μg/dL respectively, with 35.1%, 38.9% and 0% of children who had BLLs above 10 μg/dL. The BLLs in exposed areas were much higher than those in the control area. Lanxi children had higher creatinine and calcium than Chun'an children, and Luqiao children had higher δ-ALA and lower calcium than Chun'an children. No significant differences of IQ were observed between Lanxi, Luqiao and Chun'an, however a negative relationship between BLLs and IQ was shown for the study children. The results indicated that lead pollution from e-waste recycling and tinfoil processing appears to be a potential serious threat to children's health. Copyright © 2012 Elsevier B.V.

Loucks, Jeff; Mutschler, Christina; Meltzoff, Andrew N

2017-09-01

Children's imitation of adults plays a prominent role in human cognitive development. However, few studies have investigated how children represent the complex structure of observed actions which underlies their imitation. We integrate theories of action segmentation, memory, and imitation to investigate whether children's event representation is organized according to veridical serial order or a higher level goal structure. Children were randomly assigned to learn novel event sequences either through interactive hands-on experience (Study 1) or via storybook (Study 2). Results demonstrate that children's representation of observed actions is organized according to higher level goals, even at the cost of representing the veridical temporal ordering of the sequence. We argue that prioritizing goal structure enhances event memory, and that this mental organization is a key mechanism of social-cognitive development in real-world, dynamic environments. It supports cultural learning and imitation in ecologically valid settings when social agents are multitasking and not demonstrating one isolated goal at a time.

The purpose of this study was to investigate the change of the plasma oxidative stress level in children with IgA nephropathy (IgAN) and analyze its relativity to the clinical and pathological classification. To discuss the early effects of angiotensin-converting enzyme inhibitors (ACEIs) on the plasma oxidative stress level in children with IgA nephropathy. Thirty-eight children with IgAN were divided into groups according to their clinical features, pathologic grades, and treatments. Twenty healthy children were included in the control group. The plasma level of advanced oxidation protein products (AOPPs), malonaldehyde (MDA), and superoxide dismutase (SOD) were detected. The plasma level of oxidative stress was significantly increased in the IgAN group, including a higher plasma level of AOPP and MDA and a lower plasma level of SOD. After treatment, the plasma level of oxidative stress was significantly decreased in the ACEI group. The children with IgAN had an increase in the plasma level of oxidative stress, expressed as an increased plasma level of AOPP and MDA and a decreased plasma level of SOD. Oxidative stress was associated with the progression of IgAN in children. Early treatment with ACEI therapy can significantly reduce the plasma level of oxidative stress in children with IgAN. © The Author(s) 2016.

Scope The study aims to evaluate the status of dietary exposure to aflatoxin and fumonisin in young Tanzanian children, using previously validated biomarkers of exposure. Methods and results A total of 148 children aged 12 to 22 months, were recruited from three geographically distant villages in Tanzania; Nyabula, Kigwa and Kikelelwa. Plasma aflatoxin-albumin adducts (AF-alb) and urinary fumonisin B1 (UFB1) were measured by ELISA and LC-MS, respectively. AF-alb was detectable in 84% of children, was highest in fully weaned children (p<0.01) with higher levels being associated with higher maize intake (p<0.05). AF-alb geometric mean (95% CI) was 43.2 (28.7–65.0), 19.9 (13.5–29.2) and 3.6 (2.8–4.7) pg/mg albumin in children from Kigwa, Nyabula and Kikelelwa, respectively. UFB1 was detectable in 96% of children and the level was highest in children who had been fully weaned (p<0.01). The geometric UFB1 mean (95% CI) was 327.2 (217.1–493.0), 211.7 (161.1–278.1) and 82.8 (58.3–117.7) pg/ml in Kigwa, Nyabula and Kikelelwa, respectively. About 82% of all the children were exposed to both mycotoxins. Conclusion Young children in Tanzania are chronically exposed to both aflatoxin and fumonisin through contaminated diet, although the level of exposure varies markedly between the three villages studied.

To compare stump sensibility in children with upper limb reduction deficiency with sensibility of the unaffected arm and hand. In addition, to evaluate the associations between stump sensibility, stump length and activity level. Cross-sectional study. Children and young adults aged 6-25 years with upper limb reduction deficiency. Threshold of touch was measured with Semmes-Weinstein monofilaments, stereognosis was measured with the Shape-Texture Identification test and kinaesthesia and activity level was measured with the Child Amputee Prosthetics Project - Functional Status Inventory and the Prosthetic Upper Extremity Functional Index. A total of 31 children with upper limb reduction deficiency (mean age 15 years, 3 prosthesis wearers) were investigated. The threshold of touch of the stump circumference was lower (indicating higher sensibility) than of the unaffected arm (p = 0.006), hand (p = 0.004) and stump end-point (p = < 0.001). Long stumps had higher threshold of touch (indicating lower sensibility) than short stumps (p = 0.046). Twenty-nine children recognized 1 or more shapes or textures with the stump. Kinaesthesia in the affected and unaffected sides was comparable. Sensibility was not correlated with activity level. Threshold of touch, stereognosis and kinaesthesia of the affected sides were excellent. Threshold of touch of the stump circumference was lower (indicating higher sensibility) than of the unaffected arm and hand. High stump sensibility may clarify good functioning in the children without prostheses and contribute to prosthesis rejection.

Objectives Indoor air pollution levels are reported to be higher with biomass fuel, and a number of respiratory diseases in children are associated with pollution from burning such fuel. However, little is known about the situation in developing countries. The aim of the study was to compare indoor air pollution levels and prevalence of symptoms in children between biomass- and fossil-fuel-using households in different seasons in Bangladesh. Methods We conducted a cross-sectional study among biomass- (n = 42) and fossil-fuel (n = 66) users having children <5 years in Moulvibazar and Dhaka, Bangladesh. Health-related information of one child from each family was retrieved once in winter (January 2008) and once in summer (June 2008). The measured pollutants were carbon monoxide (CO), carbon dioxide (CO2), dust particles, volatile organic compounds (VOCs), and nitrogen dioxide. Results Mean concentration of dust particles and geometric mean concentrations of VOCs such as benzene, toluene, and xylene, which were significantly higher in biomass- than fossil-fuel-users’ kitchens (p < 0.05), were significantly higher in winter than in summer (p < 0.05). Levels of CO and CO2, which were significantly higher in biomass than fossil-fuel users (p < 0.05), were significantly higher in summer than winter (p < 0.05). However, no significant difference was found in the occurrence of symptoms between biomass- and fossil-fuel users either in winter or in summer. Conclusions It was suggested that the measured indoor air pollution did not directly result in symptoms among children. Other factors may be involved. PMID:21432551

Triage tools have an important role in pandemics to identify those most likely to benefit from higher levels of care. We compared Community Assessment Tools (CATs), the CURB-65 score, and the Pandemic Medical Early Warning Score (PMEWS); to predict higher levels of care (high dependency--Level 2 or intensive care--Level 3) and/or death in patients at or shortly after admission to hospital with A/H1N1 2009 pandemic influenza. This was a case-control analysis using retrospectively collected data from the FLU-CIN cohort (1040 adults, 480 children) with PCR-confirmed A/H1N1 2009 influenza. Area under receiver operator curves (AUROC), sensitivity, specificity, positive predictive values and negative predictive values were calculated. CATs best predicted Level 2/3 admissions in both adults [AUROC (95% CI): CATs 0.77 (0.73, 0.80); CURB-65 0.68 (0.64, 0.72); PMEWS 0.68 (0.64, 0.73), p<0.001] and children [AUROC: CATs 0.74 (0.68, 0.80); CURB-65 0.52 (0.46, 0.59); PMEWS 0.69 (0.62, 0.75), p<0.001]. CURB-65 and CATs were similar in predicting death in adults with both performing better than PMEWS; and CATs best predicted death in children. CATs were the best predictor of Level 2/3 care and/or death for both adults and children. CATs are potentially useful triage tools for predicting need for higher levels of care and/or mortality in patients of all ages.

To analyze the associations between socioeconomic status (SES) indicators and physical activity and overweight/obesity in children. 485 children wore accelerometers for 7 days. Variables included time in sedentary behavior and moderate-to-vigorous physical activity (MVPA), and steps/day. Children were further categorized as meeting or not meeting guidelines of ≥60min/day MVPA and ≥12,000 steps/day. Body mass index (BMI) and body fat percentage (BF%) were measured using bioelec-trical impedance. Overweight/obesity was defined as BMI>+1 SD and BF%≥85th percentile. Parents answered questionnaires that questioned total annual household income, parental education level, parental employment status and automobile ownership. Children averaged 59.5min/day in MVPA (44.1% met MVPA guidelines), and 9639 steps/day (18.4% met steps/day guidelines). 45.4% and 33% were overweight/obese classified by BMI and BF% respectively. Higher relative total annual household income level (Odds Ratio 0.31; 95% confidence interval=0.15-0.65), and relatively higher maternal (OR=0.38; 95%CI=0.20-0.72) and paternal (OR=0.36; 95%CI=0.17-0.75) education levels were associ-ated with lower odds of children meeting MVPA guidelines. Household automobile ownership was associated with lower odds of children meeting MVPA (OR=0.48; 95%CI=0.31-0.75) and steps/day guidelines (OR=0.44; 95%CI=0.26-0.74). SES indicators were not associated with overweight/obesity, but higher SES was associated with lower odds of children meeting MVPA guidelines. Copyright © 2015 Sociedade de Pediatria de São Paulo.

To determine the level of malnutrition and xerophthalmia in pre-school children. Non-randomised community based study. Four different administrative regions: Harari, Tigray, Southern Nation Nationalities and people region (SNNPR) and Oromiya, with different eco-zones, were studied from May to June 1996. Fifteen thousand and eighty seven children, aged between six and 71 months, examined for clinical symptoms and signs of xerophthalmia. Anthropometry and blood samples were taken from every 20 children (n = 634) of same age, for serum retinol and nutritional determination. INTERVENTION MEASURES: Disease targeted approach of vitamin A supplementation was employed in the regions. The overall prevalence rates of night blindness and Bitot's spots exceeded WHO cut-off point for xerophthalmia as a public health problem, with higher prevalence rates in males (53%) than females (26%). The proportion of children with deficient serum retinol concentrations (SRC), and Bitot's spot were observed to be higher in Oromiya and Harari regions followed by Tigray, than SNNPR administrative regions. Most of the affected children were aged between 36 and 72 months. The greatest low SRC was also observed in the same age group of children in all regions. There was higher prevalence rate of stunting (60.1%) than wasting (12.2%) with an additional (8.8%) of children both stunted and wasted. The proportion of stunted children was high in Tigray followed by Oromiya, SNNPR and Harari regions. The high level of stunting and Bitot's spot, together with the low level of serum retinol concentrations found in these regions, indicates the need to strengthen this intervention strategy further with universal vitamin A capsule distribution, nutrition education and promotion of horticulture activities.

The current study investigated the influence of cardiorespiratory fitness on arithmetic cognition in forty 9–10 year old children. Measures included a standardized mathematics achievement test to assess conceptual and computational knowledge, self-reported strategy selection, and an experimental arithmetic verification task (including small and large addition problems), which afforded the measurement of event-related brain potentials (ERPs). No differences in math achievement were observed as a function of fitness level, but all children performed better on math concepts relative to math computation. Higher fit children reported using retrieval more often to solve large arithmetic problems, relative to lower fit children. During the arithmetic verification task, higher fit children exhibited superior performance for large problems, as evidenced by greater d' scores, while all children exhibited decreased accuracy and longer reaction time for large relative to small problems, and incorrect relative to correct solutions. On the electrophysiological level, modulations of early (P1, N170) and late ERP components (P3, N400) were observed as a function of problem size and solution correctness. Higher fit children exhibited selective modulations for N170, P3, and N400 amplitude relative to lower fit children, suggesting that fitness influences symbolic encoding, attentional resource allocation and semantic processing during arithmetic tasks. The current study contributes to the fitness-cognition literature by demonstrating that the benefits of cardiorespiratory fitness extend to arithmetic cognition, which has important implications for the educational environment and the context of learning.

Exposure determinants of cadmium in European mothers and their children

DOE Office of Scientific and Technical Information (OSTI.GOV)

Berglund, Marika, E-mail: marika.berglund@ki.se; Larsson, Kristin; Grandér, Margaretha

The metal cadmium (Cd) is a widespread environmental pollutant with documented adverse effects on the kidneys and bones from long-term environmental exposure, but with insufficiently elucidated public health consequences such as risk of cardiovascular disease, hormone-related cancer in adults and developmental effects in children. This study is the first pan-European human biomonitoring project that succeeded in performing harmonized measurements of Cd in urine in a comparable way in mother–child couples from 16 European countries. The aim of the study was to evaluate the overall Cd exposure and significant determinants of Cd exposure. A study population of 1632 women (24–52 yearsmore » of age), and 1689 children (5–12 years of age), from 32 rural and urban areas, was examined within a core period of 6 months in 2011–2012. Women were stratified as smokers and non-smokers. As expected, smoking mothers had higher geometric mean (gm) urinary cadmium (UCd; 0.24 µg/g crea; n=360) than non-smoking mothers (gm 0.18 µg/g crea; n=1272; p<0.0001), and children had lower UCd (gm 0.065 µg/g crea; n=1689) than their mothers at the country level. Non-smoking women exposed to environmental tobacco smoke (ETS) at home had 14% (95% CI 1–28%) higher UCd than those who were not exposed to ETS at home (p=0.04). No influence of ETS at home or other places on UCd levels was detected in children. Smoking women with primary education as the highest educational level of the household had 48% (95% CI 18–86%) higher UCd than those with tertiary education (p=0.0008). The same observation was seen in non-smoking women and in children; however they were not statistically significant. In children, living in a rural area was associated with 7% (95% CI 1–13%) higher UCd (p=0.03) compared to living in an urban area. Children, 9–12 years had 7% (95% CI 1–13%) higher UCd (p=0.04) than children 5–8 years. About 1% of the mothers, and 0.06% of the children, exceeded the tolerable weekly intake (TWI) appointed by EFSA, corresponding to 1.0 µg Cd/g crea in urine. Poland had the highest UCd in comparison between the 16 countries, while Denmark had the lowest. Whether the differences between countries are related to differences in the degree of environmental Cd contamination or to differences in lifestyle, socioeconomic status or dietary patterns is not clear. - Highlights: • Comparable measures of urinary Cd for mother–child couples in 16 countries were achieved. • Main urinary Cd predictors were age, smoking, educational level and rural residence. • Mean urinary Cd in children differed by a factor of 7 between countries. • Among non-smoking and smoking women the difference was 3-fold between countries. • The margin between current exposure levels and suspected health effect levels is narrow.« less

This study investigated the relationship among working memory, processing speed, math performance, and reactivity to stress in 83 Grade 1 children. Specifically, 39 children with math disability (MD) were compared to 44 children who are typically achieving (TA) in mathematics. It is the first study to use a physiological index of stress (salivary cortisol levels) to measure children's reactivity while completing tasks that assess the core components of MD: working memory for numbers, working memory for words, digits backward, letter number sequence, digit span forward, processing speed for numbers and words, block rotation, and math tasks. Grade 1 children with MD obtained significantly lower scores on the letter number sequence and quantitative concepts tasks. Higher levels of reactivity significantly predicted poorer performance on the working memory for numbers, working memory for words, and quantitative concepts tasks for Grade 1 children, regardless of math ability. Grade 1 children with MD and higher reactivity had significantly lower scores on the letter number sequence task than the children with MD and low reactivity. The findings suggest that high reactivity impairs performance in working memory and math tasks in Grade 1 children, and young children with high reactivity may benefit from interventions aimed at lowering anxiety in stressful situations, which may improve learning. © Hammill Institute on Disabilities 2012.

BACKGROUND Primitive electronic waste (e-waste) recycling creates exposures to several hazardous substances including lead. In Uruguay, primitive recycling procedures are a significant source of lead exposure. OBJECTIVES The aim of this study was to examine lead exposure in blood lead levels (BLLs) in low-income children exposed to lead through burning cables. METHODS A sample of children and adolescents exposed to lead through burning cable activities were assessed at the Department of Toxicology in Montevideo, Uruguay, between 2010 and 2014. Soil lead levels of residences were taken shortly after their assessment. FINDINGS The final sample included 69 children and adolescents (mean age 7.89 years). More than 66% of participants had an additional source of lead exposure—manual gathering of metals—and <5% were exposed to lead through landfills or paint. Average BLLs at first consultation were 9.19 ug/dL and lower at the second measurement (5.86 μg/dL). Data from soil lead levels ranged from 650 to 19,000 mg of lead/kg of soil. The interventions conducted after the assessment included family education in the clinic and at home, indoor and outdoor remediation. We found a decrease in BLLs of 6.96 μg/dL. Older children had lower BLLs (r = −0.24; P =0.05). Statistical analyses also showed that children living in areas with higher soil lead levels had significantly higher BLLs (r = 0.50; P < 0.01). Additionally, we found greater BLLs from burning cable activities when children had been exposed to lead-based paint (r = 0.23; P < 0.1). CONCLUSION Among children exposed to e-waste recycling, the most common additional source of lead exposure was the manual gathering of metals. The average BLL among children and adolescents in this study is higher than the BLLs currently suggested in medical intervention. Future research should focus on exploring effective interventions to reduce lead exposure among this vulnerable group. PMID:27325077

It has been hypothesised that light skin pigmentation has arisen to ensure adequate levels of vitamin D as human populations moved out of Africa and into higher latitudes. Vitamin D, which is primarily obtained through exposure to sunlight (specifically ultraviolet radiation B (UVR-B)), has been inversely associated with several complex diseases. Greater sun exposure, on the other hand, is a well-known cause of skin cancer. The potential of UVR to be beneficial for some health outcomes but detrimental for others has prompted a public health debate on how to balance the positive and negative consequences of sun exposure. In this study we aimed to determine the validity of the evolutionary hypothesis linking lighter skin with higher vitamin D concentrations in a European population. Additionally, we aimed to examine the influence of pigmentation on personal behaviour towards sunlight exposure and the effects of this behaviour on vitamin D. We combined genetic variants strongly associated with skin colour, tanning or freckling to create genetic scores for each of these phenotypes. We examined the association of the scores with pigmentary traits, sun exposure and serum 25-hydroxyvitamin D (25(OH)D) levels among children of the Avon Longitudinal Study of Parents and Children (ALSPAC, N = 661 to 5649). We found that fairer-skinned children, i.e. those with higher pigmentation score values, had higher levels of 25(OH)D (0.6 nmol/l; 95% CI 0.2, 1.0; per unit increase in skin colour score; N = 5649). These children also used more protection against the damaging effects of UVR. In this population taking protective measures against sunburn and skin cancer does not seem to remove the positive effect that having a less pigmented skin has on vitamin D production. Our findings require further replication as skin pigmentation showed only a small effect on circulating 25(OH)D.

The aim of this study was to examine the relationship between children's experiences of three different types of violence and academic achievement among primary school children in Kingston, Jamaica. A cross-sectional study of 1300 children in grade 5 [mean (S.D.) age: 11 (0.5) years] from 29 government primary schools in urban areas of Kingston and St. Andrew, Jamaica, was conducted. Academic achievement (mathematics, reading, and spelling) was assessed using the Wide Range Achievement Test. Children's experiences of three types of violence - exposure to aggression among peers at school, physical punishment at school, and exposure to community violence - were assessed by self-report using an interviewer administered questionnaire. Fifty-eight percent of the children experienced moderate or high levels of all three types of violence. Boys had poorer academic achievement and experienced higher levels of aggression among peers and physical punishment at school than girls. Children's experiences of the three types of violence were independently associated with all three indices of academic achievement. There was a dose-response relationship between children's experiences of violence and academic achievement with children experiencing higher levels of violence having the poorest academic achievement and children experiencing moderate levels having poorer achievement than those experiencing little or none. Exposure to three different types of violence was independently associated with poor school achievement among children attending government, urban schools in Jamaica. Programs are needed in schools to reduce the levels of aggression among students and the use of physical punishment by teachers and to provide support for children exposed to community violence. Children in Jamaica and the wider Caribbean experience significant amounts of violence in their homes, communities, and schools. In this study, we demonstrate a dose-response relationship between primary school children's experiences of three different types of violence and their academic achievement. The study points to the need for validated violence prevention programs to be introduced in Jamaican primary schools. Such programs need to train teachers in appropriate classroom management and discipline strategies and to promote children's social and emotional competence and prevent aggression.

Plasma-soluble CD30 (sCD30) is the result of proteolytic splicing from the membrane-bound form of CD30, a putative marker of type 2 cytokine-producing cells. We measured sCD30 levels in children with tuberculosis, a disease characterized by prominent type 1 lymphocyte cytokine responses. We postulated that disease severity and nutritional status would alter cytokine responses and therefore sCD30 levels. Samples from South African children enrolled prospectively at the time of diagnosis of tuberculosis were analyzed. (Patients were originally enrolled in a randomized, double-blind placebo-controlled study of the effects of oral vitamin A supplementation on prognosis of tuberculosis.) Plasma samples collected at the time of diagnosis and 6 and 12 weeks later (during antituberculosis therapy) were analyzed. sCD30 levels were measured by enzyme immunoassay. The 91 children included in the study demonstrated high levels of sCD30 at diagnosis (median, 98 U/liter; range, 11 to 1,569 U/liter). Although there was a trend toward higher sCD30 levels in more severe disease (e.g., culture-positive disease or miliary disease), this was not statistically significant. Significantly higher sCD30 levels were demonstrated in the presence of nutritional compromise: the sCD30 level was higher in patients with a weight below the third percentile for age, in those with clinical signs of kwashiorkor, and in those with a low hemoglobin content. There was minimal change in the sCD30 level after 12 weeks of therapy, even though patients improved clinically. However, changes in sCD30 after 12 weeks differed significantly when 46 patients (51%) who received vitamin A were compared with those who had received a placebo. Vitamin A-supplemented children demonstrated a mean (+/- standard error of the mean) decrease in sCD30 by a factor of 0.99 +/- 0.02 over 12 weeks, whereas a factor increase of 1.05 +/- 0.02 was demonstrated in the placebo group (P = 0.02). We conclude that children with tuberculosis had high sCD30 levels, which may reflect the presence of a type 2 cytokine response. Nutritional compromise was associated with higher sCD30 levels. Vitamin A therapy resulted in modulation of sCD30 levels over time.

We studied the factors that predict liking for vegetables and preference for a variety of vegetables among schoolchildren. Additionally, we examined if there were gender differences in the predictors that explain the hypothesized higher scores in liking vegetables and preferences among girls. The data from the PRO GREENS project included 424 Finnish children (response rate 77%) aged 11 to 12. The children completed validated measures about social and environmental factors related to their liking for vegetables and preferences both at baseline 2009 and follow-up 2010. The associations were examined with regression and mediation analyses. The strongest predictors of both girls' and boys' liking and preferences were higher levels of eating vegetables together with the family, previous vegetable intake and a lower level of perceived barriers. Liking was additionally predicted by a lower level of parental demand that their child should eat vegetables. Girls reported higher levels of liking and preferences in the follow-up. This gender difference was mainly explained by girls' lower level of perceived barriers related to vegetable intake and girls' higher previous vegetable intake. Interventions that aim to increase the low vegetable intake among boys by increasing their liking for vegetables and preference for a variety of vegetables could benefit from targeting perceived barriers, namely boys' perception and values concerning the consumption of vegetables.

Observed differentials in the levels of selected environmental contaminants among Mexican and other Hispanic American children, adolescents, adults, and senior citizens.

Starting with the 2007-2008 cycle, the National Health and Nutrition Examination Survey (NHANES) also oversampled Hispanics other than Mexicans (OHISP) making it possible to treat OHISP as a separate demographic group along with Mexican Americans (MAs), non-Hispanic whites (NHWs), and non-Hispanic blacks (NHBs). Yet, more often than not, OHISP have been merged with MA to form an all-Hispanic demographic group (HISP) thus limiting comparisons between NHW, NHB, and HISP. Consequently, for the first time, this study was undertaken to evaluate differences in the observed levels of selected environmental contaminants between MA and OHISP from five groups of environmental contaminants, namely, polycyclic aromatic hydrocarbons (PAHs), iodine uptake inhibitors (IUIs), environmental phenols (EPHs), priority pesticides (PPs), and perfluoroalkyl acids (PFAAs). Data for 2007-2010 from NHANES were used to conduct this study. OHISP children born in USA had higher levels of selected PAH metabolites than USA-born MA, and Mexican-born MA adolescents had higher levels of selected PAH metabolites than USA-born MA adolescents. USA-born adolescent MA had higher levels of selected parabens than USA-born adolescent OHISP, and OHISP adults born in another Spanish-speaking country had higher levels of selected parabens than USA-born OHISP adults. USA-born MA adults and seniors had higher levels of selected dichlorophenols than Mexico-born MA adults and seniors, respectively. Females had higher levels of selected PAH metabolites, EPHs, and PPs than males among children, adolescents, adults, and seniors, but the reverse was true for the levels of selected IUIs and PFAAs among adolescents and seniors. Smokers had higher levels of almost all PAH metabolites than non-smokers for adolescents, adults, and seniors. The same was true for urinary thiocynate for adolescents, adults, and seniors. OHISP is a multiracial multiethnic demographic group substantially different from MA with possibly different smoking behavior and with possibly differential levels of exposure to certain environmental contaminants and as such should be treated as a demographic group by itself.

Children with autism often suffer from sleep disturbances, and compared to age-matched controls, have decreased melatonin levels, as indicated by urine levels of the primary melatonin metabolite, 6-sulfatoxymelatonin (6-SM). We therefore investigated the relationship between 6-SM levels and sleep architecture in children with autism spectrum disorders (ASD). Twenty-three children, aged 4-10 years, completed two nights of polysomnography and one overnight urine collection for measurement of urinary 6-SM excretion rate. Parents completed the Children's Sleep Habits Questionnaire. We found that higher urinary 6-SM excretion rates were associated with increased N3 sleep, decreased N2 sleep, and decreased daytime sleepiness. The results warrant further examination to examine the effects of supplemental melatonin on sleep architecture and daytime sleepiness.

A number of studies have reported that parents of autistic children face higher levels of stress, but few studies examined the stress associated with the home care of children with pervasive developmental disorders (PDD) other than autistic disorder. The aims of the present study were therefore to (i) evaluate the emotional stress level of parents caring for their children with PDD; and (ii) explore the correlates of their emotional stress. Participants were 147 families (147 mothers and 122 fathers) of 158 children with PDD (42 with autistic disorder, 35 with Asperger's disorder and 81 with PDD not otherwise specified). K6 was used to measure the stress level of the parents. Marital relationships and personality were assessed with the Intimate Bond Measure and the NEO Five-Factor Inventory, respectively. The parents also rated the characteristics of their children with PDD through the Pervasive Developmental Disorder-Autism Society Japan Rating Scale (PARS). The mean K6 score of the mothers was significantly higher than that of the women in the general population in Japan. Stepwise multiple regression indicated that the emotional stress of the mothers was correlated with the personality traits of Neuroticism and Agreeableness, perceived Control by the husband, and the children's PARS score. Clinicians can deliver better service by paying appropriate attention to the emotional distress of mothers of children with not only autistic disorder but also other PDD.

To investigate the effect of phthalates exposure from drinking water on children's intelligence and secretion of thyroid hormone. Two villages in S County were selected randomly as polluted area and control area according to the distance from the Shaying river basin. Phthalates including DEP, DBP, DMP, DEHP were measured both in the river water and drinking water using HPLC method. Children aged 8 to 13 years old studying in the village primary school were recruited by cluster sampling (n = 154). The combined Reven Test was used to test children intelligence and ELISA method was used to determined thyroid hormone levels. The concentrations of phthalates (DEP, DBP) were exceeding standards of surface water quality in any of the three sections of the river. Compared to the control area, the concentration of DEP and DBP in drinking water were significant higher in the polluted area than that in control area (P < 0.05). Children from polluted area had significant higher FT4 concentration compared to children from control area (P < 0.05). Intelligence level in children from polluted area was lower than that from control area (P < 0.05). The drinking water has been polluted by Shaying river and thyroid hormones levels of children were affected in the polluted areas. It is necessary to verify if this change is related to the phthalates.

In the United Kingdom, child maltreatment is an area of increased awareness and concern. To compare the dental health of children subject to child protection plans with controls. Children had to be aged between two and 11 years, medically healthy, and subject either to a child protection plan or attending the paediatric outpatient orthopaedic or general surgery clinics (control group). All children had a standardized oral examination. Seventy-nine children were examined in each group. Children with child protection plans had statistically higher levels of primary tooth decay than controls (mean dmft 3.82 and 2.03, Mann-Whitney U test P = 0.002). After adjusting for socioeconomic status, the incidence rate ratios for the occurrence of dental caries in the primary dentition in children with a child protection plan was 1.76 (95% CI: 1.44-2.15) relative to the controls. There was no statistical difference in the levels of permanent tooth decay between the study and control groups (mean DMFT 0.71 and 0.30, respectively). The care index was significantly lower (P = 0.008, Mann-Whitney U test) in the study group (1.69%) compared to the control group (6.02%). Children subject to child protection plans had significantly higher levels of dental caries in the primary dentition. © 2014 BSPD, IAPD and John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The objective of the research was to obtain data on the values of salivary Streptococcus mutans and Lactobacillus spp. in 12 years old children and teenagers (13 - 18 years old children), and to compare the values of these cariogenic microoorganisms in children of various ages, for the purpose of valuating the risk of caries. The sample comprised 32 persons divided into two groups. The first group included 17 children of the age of 12. The second group included 15 teenagers. The specimen of stimulated saliva, needed for the purpose of establishing the quantities of Streptococcus mutans and Lactobacillus spp., was taken by the method of CRT’-bacteria, according to manufacturers instruction. In the group of 12 years old children, the distribution of salivary Lactobacillus spp. was as follows: very low values 41,1%, low values 35,2%, high values 17,6%, very high values 5,8%, while in the group of teenagers, the results were the following: very low values 26,66%, low values 33,33%, high values 40%, very high values 0%. The levels of Streptococcus mutans were the following: 12 years old children had very low values in 41,7% cases, low values in 11,7% cases, high values in 41,7% cases, very high values in 5,8% cases, while the group of teenagers had very low values in 0%, low values in 33,3%, high values in 33,3%, and very high values in 33,3% cases. The levels of Streptococcus mutans are higher in our teenage children than in younger children, while the differences in levels of Lactobacillus spp. among children of various ages do not exist. In terms of global distribution, the levels of Streptococcus mutans and Lactobacillus spp. are higher in our population than in other countries in both control groups.

A lack of association between hyperserotonemia and the increased frequency of serum anti-myelin basic protein auto-antibodies in autistic children.

One of the most consistent biological findings in autism is the elevated blood serotonin levels. Immune abnormalities, including autoimmunity with production of brain specific auto-antibodies, are also commonly observed in this disorder. Hyperserotonemia may be one of the contributing factors to autoimmunity in some patients with autism through the reduction of T-helper (Th) 1-type cytokines. We are the first to investigate the possible role of hyperserotonemia in the induction of autoimmunity, as indicated by serum anti-myelin-basic protein (anti-MBP) auto-antibodies, in autism. Serum levels of serotonin and anti-MBP auto-antibodies were measured, by ELISA, in 50 autistic patients, aged between 5 and 12 years, and 30 healthy-matched children. Autistic children had significantly higher serum levels of serotonin and anti-MBP auto-antibodies than healthy children (P < 0.001 and P < 0.001, respectively). Increased serum levels of serotonin and anti-MBP auto-antibodies were found in 92% and 80%, respectively of autistic patients. Patients with severe autism had significantly higher serum serotonin levels than children with mild to moderate autism (P < 0.001). Serum serotonin levels had no significant correlations with serum levels of anti-MBP auto-antibodies in autistic patients (P = 0.39). Hyperserotonemia may not be one of the contributing factors to the increased frequency of serum anti-MBP auto-antibodies in some autistic children. These data should be treated with caution until further investigations are performed. However, inclusion of serum serotonin levels as a correlate may be useful in other future immune studies in autism to help unravel the long-standing mystery of hyperserotonemia and its possible role in the pathophysiology of this disorder.

Lead still remains an important problem for poor, inner-city, ethnic minority children, with a particular emphasis on lead paint and dust. In Egypt, there is no national survey about the prevalence of elevated blood lead level among children. To assess the environmental lead level as well as to determine blood lead level among primary school children and find out its relationship with their intelligent quotient (IQ), hemoglobin level, hearing impairment and school performance. 190 primary school children from rural and urban areas were selected and their blood lead levels (BLL), hemoglobin concentrations, IQ, hearing threshold and school performance were measured. Also, environmental lead level was measured in the school and home. The mean value of environmental lead (μg/m3) in urban schools air was significantly higher than that in rural areas. BLL had a significant negative correlation with hemoglobin level and IQ; it was positively correlated with the hearing threshold. With increasing BLL, the school performance of children decreased significantly. Exposure to lead would deteriorate IQ, school performance and hearing level of school children. Even in the absence of overt clinical manifestations of lead toxicity, lead intoxication should be among differential diagnosis in children presenting anemia, intellectual impairment, poor academic performance and hearing impairment.

To assess an individual child's cognitive and emotional perceptions of their cerebral palsy (CP) and how these are associated with their reported life satisfaction and their functional walking ability. Convenience sample of 48 children with cerebral palsy, GMFCS (Gross Motor Function Classification System) I-IV, mean age of 12.2 ± 2.5 years was recruited from tertiary level out-patient clinics. All children completed the Brief Illness Perception Questionnaire-Cerebral Palsy version (BIPQ-CP), Students' Life Satisfaction Scale (SLSS) and 1- and 6-min walk tests. Children with CP reported levels of global life satisfaction (mean score 31.4/42) equivalent to previous studies of typically developing children. Higher total SLSS scores were associated with lower concern about CP (rho = -0.61, p < 0.001), lower emotional impact (rho = -0.58, p < 0.001), fewer perceived consequences (rho = -0.53, p < 0.001) and perceptions of higher levels of personal control (rho = 0.40, p = 0.01). Multiple regression models using BIPQ-CP constructs found that a combination of lower level of concern and fewer perceived consequences predicted 46% of the variance in SLSS score (p < 0.001). GMFCS levels, walk distance and age were not significant predictors of life satisfaction. Life satisfaction in this group of children was strongly associated with a child's perceptions of their CP but was not associated with functional walking ability. Although the cross-sectional nature of the study precludes assumptions of causality, understanding children's cognitive and emotional beliefs about their cerebral palsy would seem to be an important adjunct to clinical management.

Compared 30 mothers whose children were hospitalized for failure-to-thrive (FTT) to a normative group on standardized measures of perceived stress and depression. Child and maternal medical and demographic data were also taken. Standardized development and feeding assessments were done. Descriptive statistics, correlational analyses, and t tests were used to describe and examine group differences. FTT children were perceived overall as more stressful, less adaptable, more inconsolable, and more unhappy than were healthy children. Child characteristics associated with higher maternal stress levels were higher birth weight, absence of organic disease or behavioral feeding problems, and higher IQ. Maternal self-report of depression, attachment to her child, sense of competence in parenting, social isolation, and relationship to spouse were not different from the normative sample.

This study examined maternal sadness and adolescents' responses to stress in the offspring (n = 72) of mothers with and without a history of depression. Mothers with a history of depression reported higher levels of current depressive symptoms and exhibited greater sadness during interactions with their adolescent children than mothers without a history of depression. Similarly, adolescent children of mothers with a history of depression experienced higher rates of internalizing and externalizing symptoms than adolescents of mothers without a history of depression. Regression analyses indicated that adolescents' use of secondary control coping mediated the relationship between observed maternal sadness and adolescents' internalizing and externalizing symptoms, in that higher levels of secondary control coping (e.g., cognitive reframing) were related to fewer symptoms. Results have implications for preventive interventions with children of mothers with a history of depression. PMID:18991125

In May 2011, a major incident involving phthalates-contaminated foodstuffs occurred in Taiwan. Di-(2-ethylhexyl) phthalate (DEHP) was added to foodstuffs, mainly juice, jelly, tea, sports drink, and dietary supplements. Concerns arose that normal pubertal development, especially reproductive hormone regulation in children, could be disrupted by DEHP exposure. To investigate the association between phthalate exposure and reproductive hormone levels among children following potential exposure to phthalate-tainted foodstuffs. A total of 239 children aged <12 years old were recruited from 3 hospitals in north, central, and south Taiwan after the episode. Structured questionnaires were used to collect the frequency and quantity of exposures to 5 categories of phthalate-contaminated foodstuffs to assess phthalate exposure in children. Urine samples were collected for the measurement of phthalate metabolites. The estimated daily intake of DEHP exposure at the time of the contamination incident occurred was calculated using both questionnaire data and urinary DEHP metabolite concentrations. Multiple regression analyses were applied to assess associations between phthalate exposure and reproductive hormone levels in children. After excluding children with missing data regarding exposure levels and hormone concentrations and girls with menstruation, 222 children were included in the statistical analyses. After adjustment for age and birth weight, girls with above median levels of urinary mono-(2-ethyl-5-hydroxyhexyl) phthalate, mono-(2-ethyl-5-oxohexyl) phthalate, and sum of mono-(2-ethylhexyl) phthalate concentrations had higher odds of above median follicle-stimulating hormone concentrations. Girls with above median estimated average daily DEHP exposures following the contamination episode also had higher odds of sex hormone-binding globulin above median levels. Phthalate exposure was associated with alterations of reproductive hormone levels in girls.

This study examines preadolescents’ reports of risk-taking as predicted by two different, but related inhibitory control systems involving sensitivity to reward and loss on the one hand, and higher order processing in the context of cognitive conflict, known as executive functioning (EF), on the other. Importantly, this study examines these processes with a sample of inner-city, low-income preadolescents and as such examines the ways in which these processes may be related to risky behaviors as a function of children's levels of both concurrent and chronic exposure to household poverty. As part of a larger longitudinal study, 382 children (ages 9 -11) provided a self-report of risky behaviors and participated in the Iowa Gambling task, assessing bias for infrequent loss (preference for infrequent, high magnitude versus frequent, low magnitude loss) and the Hearts and Flowers task assessing executive functioning. Results demonstrated that a higher bias for infrequent loss was associated with higher risky behaviors for children who demonstrated lower EF. Furthermore, bias for infrequent loss was most strongly associated with higher risk-taking for children facing highest levels of poverty. Implications for early identification and prevention of risk-taking in inner-city preadolescents are discussed. PMID:26412918

The aim of this study was to verify whether socioeconomic determinants, such as parents' educational level, family income and dental service attendance by children, are associated with the presence of caries among an Italian population of children. An observational retrospective study was carried out in a population of children aged 4-14 years who visited the Paediatric Dentistry Department of the University of Perugia, Italy. Children were stratified according to familial socioeconomic level (father's and mother's educational level, family income) and dental service attendance of children. Age- and sex- adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated by means of multivariate logistic regression models. A sample of 231 children (mean age 8.1 yrs, SD 2.6; 127 males, 104 females) was recruited. One hundred and sixty three (70.46%) children in the study had caries. Caries presence in children was higher in children where the mothers' educational level was lower (OR =6.1; 95% CI = 3.1 to 12.7), in children where the fathers' educational level was lower (OR =2.9; 95% CI =1.6 to 5.5) and in children with lower family income (OR = 9.9; 95% 95% CI = 5.1 to 20.1). No statistically significant difference were observed in terms of caries presence between the children who were visited at least once by a dentist and children who were not previously seen by a dental practitioner (OR = 0.8; 95% CI = 0.4 to 1.6). Socioeconomic level was an important predictor of caries presence among children. Both low income and low parental educational level were related to an increased presence of caries, whereas previous dental visits experience did not affect caries presence in children.

The experimental study of cumulative culture and the innovations essential to it is a young science, with child studies so rare that the scope of cumulative cultural capacities in childhood remains largely unknown. Here we report a new experimental approach to the inherent complexity of these phenomena. Groups of 3-4-year-old children were presented with an elaborate array of challenges affording the potential cumulative development of a variety of techniques to gain increasingly attractive rewards. In contrast to a prior study, we found evidence for elementary forms of cumulative cultural progress, with inventions of solutions at lower levels spreading to become shared innovations, and some children then building on these to create more advanced but more rewarding innovations. This contrasted with markedly more constrained progress when children worked only by themselves, or if groups faced only the highest-level challenges from the start. Further experiments that introduced higher-level inventions via the inclusion of older children, or that created ecological change, with the easiest habitual solutions no longer possible, encouraged higher levels of cumulative innovation. Our results show children are not merely 'cultural sponges', but when acting in groups, display the beginnings of cycles of innovation and observational learning that sustain cumulative progress in problem solving.This article is part of the themed issue 'Process and pattern in innovations from cells to societies'. © 2017 The Author(s).

Carlsson, Malin; Olsson, Ingrid; Hagberg, Gudrun; Beckung, Eva

2008-10-01

The aim of the study was to describe behavioural problems in children with cerebral palsy (CP) with and without epilepsy. The children were sampled from the Western Sweden CP register and were part of a European Union project. The Strength and Difficulties Questionnaire and questions on epilepsy were answered by one parent of each child. Medical records were reviewed. Parents of 83 children (44 males, 39 females) age range participated: 30 at Gross Motor Function Classification System levels I and II, and 53 at levels III to V; 60 had spastic age range 8 to 12 years (bilateral 42, unilateral 18) and 23 dyskinetic CP; 34 children had active epilepsy. The proportion of children with normal behaviour on the total difficulties score (TDS) of the Strength and Difficulties Questionnaire was significantly lower than normative data (57% vs 80%, p<0.001). Parents of 21 children (25%) considered their child's behaviour to be abnormal. Children with CP and epilepsy had a significantly higher median TDS (p=0.03) than seizure-free children. In children with aided or no walking ability, the TDS was significantly higher in those with epilepsy (p=0.04). Parents of 32 children (39%) considered their children's behaviour to have an impact on themselves and others. We conclude that behavioural problems are common in children with CP, and even more when epilepsy is present. Parents identify these problems, and professionals need to address them.

Paediatric obesity, physical activity and the musculoskeletal system.

PubMed

Shultz, S P; Anner, J; Hills, A P

2009-09-01

The current epidemic of paediatric obesity is consistent with a myriad of health-related comorbid conditions. Despite the higher prevalence of orthopaedic conditions in overweight children, a paucity of published research has considered the influence of these conditions on the ability to undertake physical activity. As physical activity participation is directly related to improvements in physical fitness, skeletal health and metabolic conditions, higher levels of physical activity are encouraged, and exercise is commonly prescribed in the treatment and management of childhood obesity. However, research has not correlated orthopaedic conditions, including the increased joint pain and discomfort that is commonly reported by overweight children, with decreases in physical activity. Research has confirmed that overweight children typically display a slower, more tentative walking pattern with increased forces to the hip, knee and ankle during 'normal' gait. This research, combined with anthropometric data indicating a higher prevalence of musculoskeletal malalignment in overweight children, suggests that such individuals are poorly equipped to undertake certain forms of physical activity. Concomitant increases in obesity and decreases in physical activity level strongly support the need to better understand the musculoskeletal factors associated with the performance of motor tasks by overweight and obese children.

To increase knowledge of physical and sexual intimate partner violence against women, its impact on women's health and children's behavioural functioning. Physical assault and sexual assault frequently co-occur. Women who experience both physical and sexual violence are at risk of poorer health outcomes than women who experience only physical violence. The behavioural functioning of children of women who experience partner violence may be adversely affected. Cross-sectional, using baseline data from a seven-year prospective study. Data related to severity of abuse (both physical and sexual) and the outcome measures of maternal (n = 300) mental health measures, risk of lethality, chronic pain and child (n = 300) behavioural functioning were analysed. Higher physical abuse scores were significantly correlated with higher sexual abuse scores, and higher levels of physical abuse were associated with higher maternal anxiety and higher child externalisation scores. Higher levels of sexual abuse were associated with higher maternal somatisation and post-traumatic stress disorder symptoms and higher child internalisation scores and total problems. These initial findings suggest that children have behavioural functioning and coping that is closely related to their mothers' functioning, which is based on the type of abuse experienced by the mothers. As we gain a greater understanding of these issues, we will be better able to develop effective policies and therapeutic interventions to help abused women and their children. Findings for the mental health functioning of women participating in this study add to the overwhelming evidence for the importance of screening for partner violence when women present for health care and for the need for effective assistance services for women who have or are currently experiencing partner violence. They also support emerging research that indicates the great need to provide effective services for the children of abused women. © 2014 John Wiley & Sons Ltd.

To examine intellectual, behavioral, and emotional functioning of children who have syndromic craniosynostosis and to explore differences between diagnostic subgroups. A national sample of children who have syndromic craniosynostosis participated in this study. Intellectual, behavioral, and emotional outcomes were assessed by using standardized measures: Wechsler Intelligence Scale for Children, Third Edition, Child Behavior Checklist (CBCL)/6-18, Disruptive Behavior Disorder rating scale (DBD), and the National Institute of Mental Health Diagnostic Interview Schedule for Children. We included 82 children (39 boys) aged 6 to 13 years who have syndromic craniosynostosis. Mean Full-Scale IQ (FSIQ) was in the normal range (M = 96.6; SD = 21.6). However, children who have syndromic craniosynostosis had a 1.9 times higher risk for developing intellectual disability (FSIQ < 85) compared with the normative population (P < .001) and had more behavioral and emotional problems compared with the normative population, including higher scores on the CBCL/6-18, DBD Total Problems (P < .001), Internalizing (P < .01), social problems (P < .001), attention problems (P < .001), and the DBD Inattention (P < .001). Children who have Apert syndrome had lower FSIQs (M = 76.7; SD = 13.3) and children who have Muenke syndrome had more social problems (P < .01), attention problems (P < .05), and inattention problems (P < .01) than normative population and with other diagnostic subgroups. Although children who have syndromic craniosynostosis have FSIQs similar to the normative population, they are at increased risk for developing intellectual disability, internalizing, social, and attention problems. Higher levels of behavioral and emotional problems were related to lower levels of intellectual functioning.

Socioeconomic Patterning in Changes in Child Exposure to Secondhand Smoke After Implementation of Smoke-Free Legislation in Wales

PubMed Central

2011-01-01

Introduction: Secondhand smoke (SHS) exposure is higher among children from lower socioeconomic status (SES) households. Legislation banning smoking in public places has been linked with reduced SHS exposure in children. However, socioeconomic patterning in responses to legislation has been little explored. Methods: A total of 3,083 children aged 10–11 years, within 75 Welsh primary schools, completed questionnaires either before legislation or 1 year later. Saliva samples were provided by 2,787 of these children for cotinine assay. Regression analyses assessed socioeconomic differences in SHS exposure, and associations of legislation with exposure among children from low, medium, and high SES households. Changes in parental smoking in the home, car-based exposure, and perceived norms were assessed. Results: SHS exposure was highest among children from lower SES households. The likelihood of providing a sample containing an undetectable level of cotinine increased significantly after legislation among children from high [relative risk ratio (RRR) = 1.44, 95% CI = 1.04–2.00] and medium SES households (RRR = 1.66, 95% CI = 1.20–2.30), while exposure among children from lower SES households remained unchanged. Parental smoking in the home, car-based SHS exposure, and perceived smoking prevalence were highest among children from low SES households. Parental smoking in the home and children’s estimates of adult smoking prevalence declined only among children from higher SES households. Conclusions: Post-legislation reductions in SHS exposure were limited to children from higher SES households. Children from lower SES households continue to have high levels of exposure, particularly in homes and cars, and to perceive that smoking is the norm among adults. PMID:21571691

Background The consequences of war violence and natural disasters on the mental health of children as well as on family dynamics remain poorly understood. Aim of the present investigation was to establish the prevalence and predictors of traumatic stress related to war, family violence and the recent Tsunami experience in children living in a region affected by a long-lasting violent conflict. In addition, the study looked at whether higher levels of war violence would be related to higher levels of violence within the family and whether this would result in higher rates of psychological problems in the affected children. Methods 296 Tamil school children in Sri Lanka's North-Eastern provinces were randomly selected for the survey. Diagnostic interviews were carried out by extensively trained local Master level counselors. PTSD symptoms were established by means of a validated Tamil version of the UCLA PTSD Index. Additionally, participants completed a detailed checklist of event types related to organized and family violence. Results 82.4% of the children had experienced at least one war-related event. 95.6% reported at least one aversive experience out of the family violence spectrum. The consequences are reflected in a 30.4% PTSD and a 19.6% Major Depression prevalence. Linear regression analyses showed that fathers' alcohol intake and previous exposure to war were significantly linked to the amount of maltreatment reported by the child. A clear dose-effect relationship between exposure to various stressful experiences and PTSD was found in the examined children. Conclusion Data argue for a relationship between war violence and violent behavior inflicted on children in their families. Both of these factors, together with the experience of the recent Tsunami, resulted as significant predictors of PTSD in children, thus highlighting the detrimental effect that the experience of cumulative stress can have on children's mental health.

Overweight and obesity are a public health problem worldwide affecting adults and children as well. The aim of this study was to assess overweight, lipid profile and cardiovascular risk ratios in 390 preschool children from low socio-economic level from Valencia, Venezuela. Nutritional anthropometric evaluation measured by body dimensions, and serum determination of cholesterol, triglycerides, HDL-cholesterol, LDL-cholesterol and cardiovascular risk factors, were determined. 95% of the children were in relative and critical poverty. 14.3% of undernutrition and 20.8% of overweight was found. Lipid profile was in normal range, with no significant differences by sex, but higher values for HDL-cholesterol and risk ratios were found in children aged 1 to 3.99 years. Even though no differences were found by nutritional status, overweight children had higher values for lipids, except HDL-cholesterol. 6.3% of overweight children had cholesterol > or =170 mg/dL, 16.5% LDL-cholesterol > or =110 mg/dL, 40.5% triglycerides > or =75mg/dL and 100% HDL-cholesterol <45 mg/dL. Overweight and lipid profile alterations were present in an important group of the children, which increase their risk of obesity and chronic non-transmissible diseases. Nutritional and educational intervention should be addressed.

The Preschool Language Scale, Fourth Edition (PLS-4; Zimmerman, Steiner, & Pond, 2002) was used to examine syntactic and semantic language skills in preschool children with autism spectrum disorders (ASD) to determine its suitability for use with this population. We expected that PLS-4 performance would be better in more intellectually able children and that receptive skills would be relatively more impaired than expressive abilities, consistent with previous findings in the area of vocabulary. Our sample consisted of 294 newly diagnosed preschool children with ASD. Children were assessed via a battery of developmental measures, including the PLS-4. As expected, PLS-4 scores were higher in more intellectually able children with ASD, and overall, expressive communication was higher than auditory comprehension. However, this overall advantage was not stable across nonverbal developmental levels. Expressive skills were significantly better than receptive skills at the youngest developmental levels, whereas the converse applied in children with more advanced development. The PLS-4 can be used to obtain a general index of early syntax and semantic skill in young children with ASD. Longitudinal data will be necessary to determine how the developmental relationship between receptive and expressive language skills unfolds in children with ASD.

This study reports on 170 Israeli school children at risk for missile attack during the Persian Gulf War. The Bar-Ilan Picture Test for Children (Itskowitz & Strauss, 1982, 1986) was specially adapted to the war situation specifically to measure children's affective reactions and coping strategies. Children with a greater sense of control and social support, and more complex defenses, tended to demonstrate better coping strategies. Children who were less defensive showed higher levels of anxiety under stress. Children scoring higher in social support showed greater perceived control over their immediate environment and more verbal expressivity with respect to the crisis situation. Girls scored higher than boys on emotional and verbal expressiveness. These data, elicited through semiprojective procedures, are consistent with much of the prior research based mainly on objective scales or self-report questionnaires. Overall, the results lend additional validity to the nexus of relations (largely established through conventional objective scales) between resources, coping, and outcomes in a naturalistic stressor situation.

Lead pollution incidents have occurred frequently in mainland China, which has caused many lead poisoning incidents. This paper took a battery recycling factory as the subject, and focused on measuring the blood lead levels of environmental samples and all the children living around the factory, and analyzed the relationship between them. We collected blood samples from the surrounding residential area, as well as soil, water, vegetables. The atomic absorption method was applied to measure the lead content in these samples. The basic information of the generation procedure, operation type, habit and personal protect equipment was collected by an occupational hygiene investigation. Blood lead levels in 43.12% of the subjects exceeded 100 μg/L. The 50th and the 95th percentiles were 89 μg/L and 232 μg/L for blood lead levels in children, respectively, and the geometric mean was 94 μg/L. Children were stratified into groups by age, gender, parents' occupation, distance and direction from the recycling plant. The difference of blood lead levels between groups was significant (p < 0.05). Four risk factors for elevated blood lead levels were found by logistic regression analysis, including younger age, male, shorter distance from the recycling plant, and parents with at least one working in the recycling plant. The rate of excess lead concentration in water was 6.25%, 6.06% in soil and 44.44% in leaf vegetables, which were all higher than the Chinese environment standards. The shorter the distance to the factory, the higher the value of BLL and lead levels in vegetable and environment samples. The lead level in the environmental samples was higher downwind of the recycling plant.

This study investigated the relationship among working memory, processing speed, math performance, and reactivity to stress in 83 Grade 1 children. Specifically, 39 children with math disability (MD) were compared to 44 children who are typically achieving (TA) in mathematics. It is the first study to use a physiological index of stress (salivary cortisol levels) to measure children’s reactivity while completing tasks that assess the core components of MD: working memory for numbers, working memory for words, digits backward, letter number sequence, digit span forward, processing speed for numbers and words, block rotation, and math tasks. Grade 1 children with MD obtained significantly lower scores on the letter number sequence and quantitative concepts tasks. Higher levels of reactivity significantly predicted poorer performance on the working memory for numbers, working memory for words, and quantitative concepts tasks for Grade 1 children, regardless of math ability. Grade 1 children with MD and higher reactivity had significantly lower scores on the letter number sequence task than the children with MD and low reactivity. The findings suggest that high reactivity impairs performance in working memory and math tasks in Grade 1 children, and young children with high reactivity may benefit from interventions aimed at lowering anxiety in stressful situations, which may improve learning.

2015-01-01

The main aim of this study was to determine some malnutrition risk factors among children with cerebral palsy (CP). Children with CP often require the assistance of physical therapy centers. Experience suggests that, apart from physical disabilities, this group often suffers from malnutrition. Data were gathered in the hospital among 128 children aged 3-18 years who were suffering from CP. The children were admitted from 2011 to 2013 to the Center for Neurological Physical Therapy for children in the Regional Hospital No. 2. St. Queen Jadwiga in Rzeszow (RORE). Statistical analyses were conducted for data on gender, age, type of CP, motor function level according to Gross Motor Function Classification Scale (GMFCS), body mass index (BMI) and hemoglobin levels in blood. The risk of anemia differs based on gender--the risk is 6 times greater among boys than among girls (p = 0.0398). Risk of malnutrition is 3.5 times higher in children with tetraplegia than in children with diplegia or hemiplegia (p = 0.0043). Higher GMFCS scores are connected to greater proportions of malnourished children (for BMI z-score <-1.64, p = 0.0010). Among children with CP, malnourishment risk factors are male gender for anemia and tetraplegia and high GMFCS values. 2015 S. Karger AG, Basel.

A febrile seizure (FS) is the most common convulsive disorder in children. Activation of cytokine network is involved in FS pathogenesis. Adiponectin, leptin and IL-6 are the major adipocytokines secreted by fat cells. To date, only a few studies concerned the association of adipocytokines with febrile seizures. In this study, we tried to investigate serum and CSF levels of adiponectin, leptin, and interleukin-6 (IL-6); as adipocytokines, for the first time in Egyptian children with febrile seizures. This was a prospective cross-sectional study included one hundred patients with febrile seizure, and matched with age, gender, 100 children with febrile illness without seizures (febrile control, FC) and 100 healthy control group (HC). Serum and cerebrospinal fluid (CSF) levels of adiponectin, leptin, and (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA) method. Serum adiponectin was significantly higher in children with FS (16.8 ± 3.7 ug/ml) and the FC group (18.3 ± 4.3 ug/ml) compared to the HC group (9.5 ± 2.2 ug/ml); P < 0.05, respectively. Serum leptin was significantly lower in children with FS (0.9 ± 0.3 ng/ml) compared to both the FC group (4.7 ± 1.2 ng/ml) and the HC group (1.8 ± 0.4 ng/ml); P < 0.01, respectively. Children with FS had significantly higher serum IL-6 levels (43.7 ± 11.7 ng/ml) than the FC group (21.9 ± 4.5 ng/ml) and the HC group (6.5 ± 1.8 ng/ml); P < 0.01, respectively. Patients with simple febrile seizures (SFS) had serum and CSF adiponectin levels similar to those with complex febrile seizures (CFS); (P > 0.05). Serum and CSF leptin levels were significantly lower in patients with CFS compared to the SFS group (P < 0.05). Serum and CSF IL-6 levels were significantly higher in patients with CFS compared to the SFS group (P < 0.01). On multivariate logistic regression analysis, the high serum IL-6 levels was the most significant risk factor associated with febrile seizures among studied children (OR: 6.2; 95 % CI: 3.58 -10.57; P = 0.0001). Our data brought a novel observation that some adipocytokines like leptin and IL-6 could be, at least in part, an aetiopathogenetic factor in the manifestation of febrile seizures in susceptible Egyptian children. Moreover, we observed a significant association between high CSF IL-6 levels and susceptibility to complex febrile seizures as did the low CSF leptin levels.

Aim: The aim of this study was to examine the relation between body mass index (BMI) and functional level and health-related quality of life in children with cerebral palsy (CP). Material and Methods: Two hundred seventy-eight children with CP aged between 2 and 18 years were included in the study. The sociodemographic properties of the children were recorded. Their functional independence levels were assessed with WeeFIM and their health-related quality of life levels were assessed with the Child Health Questionnaire-Parent Form (PF-50). Approval was obtained from the ethics committee of Abant İzzet Baysal University Medical Faculty for this study (Number: 2008/100-77). Results: When classified by body mass index, 26.3% of the children had a normal body weight, 5.4% were overweight, 11.5% were obese and 56.8% had a low body weight. The rate of low body weight was higher in children with moderate and severe CP (52.7% and 53.8%, respectively), while the rate of obesity was higher in children with mild CP who could walk (7.1%). A significant difference was found in children with CP with a normal body weight, overweight children with CP, obese children with CP and children with CP with a low body weight in terms of the total WeeFIM score and the variables of quality of life including physical functionality and role/social limitations because of physical health (p<0.05). In the correlation analysis, a positive correlation was found between WeeFIM and BMI and the subdimensions of role/social limitations because of emotional or behavioral difficulties, pain and discomfort and self-esteem (p<0.05). Conclusions: Our results showed that BMI affected functional independence and health-related quality of life in children with CP and this was more prominent in children who had severe CP and low BMI values. More studies are needed in this area. PMID:26078648

To examine the effect of infection with Enterovirus (EV) in children with type 1 diabetes (T1D) on the activities of serum antioxidant enzymes in diabetic and nondiabetic controls. Three hundred and eighty-two diabetic and 100 nondiabetic children were tested for EV RNA using reverse transcriptase (RT)-PCR. The activities of serum superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) were also estimated in diabetic patients infected with EV (T1D-EV+), those not infected with EV (T1D-EV-), and in nondiabetic controls. The frequency of EV was higher in diabetic children (100/382; 26.2%) than in healthy controls (0/100). Levels of fasting blood glucose (FBG), glycosylated hemoglobin (HbA1c) and C-reactive protein (CRP) were significantly higher but C-peptide was significantly lower in diabetic children than in controls. CRP levels were higher in the T1D-EV+ group than in the T1D-EV- group, and higher in all diabetic children than in nondiabetic controls. The activities of the antioxidant enzymes GPx, SOD, and CAT decreased significantly in diabetic children compared to in controls. Moreover, the activities of the enzymes tested were significantly reduced in the T1D-EV+ group compared to in the T1D-EV- group. Our data indicate that EV infection correlated with a decrease in the activity of antioxidant enzymes in the T1D-EV+ group compared to in the T1D-EV- group; this may contribute to β cell damage and increased inflammation. © 2018 The Author(s) Published by S.

Objective In a recent study, we found that Greenlandic Inuit children had a more adverse metabolic profile than Danish children. Aerobic fitness and adiposity could only partly account for the differences. Therefore, we set out to evaluate and compare plasma leptin and adiponectin levels in Danish and Inuit children. Methods In total, 187 Inuit and 132 Danish children (5.7–17.1 years) had examinations of anthropometrics, body fat content, pubertal staging, fasting blood and aerobic fitness. Results Plasma leptin was higher in Danish boys [3,774 (4,741–3,005)] [pg/mL unadjusted geometric mean (95% CI)] compared to both northern [2,076 (2,525–1,706)] (p<0.001) and southern (2,515 (3,137–2,016)) (p<0.001) living Inuit boys and higher in Danish girls [6,988 (8,353–5,847)] compared to southern living Inuit girls [4,910 (6,370–3,785)] (p=0.021) and tended to be higher compared to northern living Inuit girls [5,131 (6,444–4,085)] (p=0.052). Plasma adiponectin was higher for both Danish boys [22,359 (2,573–19,428)] [ng/mL unadjusted geometric mean (95% CI)] and girls [26,609 (28,994–24,420)] compared to southern living Inuit boys [15,306 (18,406–12,728)] and girls [18,864 (22,640–15,717)] (both p<0.001), respectively. All differences remained after adjustment for body fat percentage (BF%), aerobic fitness, age and puberty. The leptin/adiponectin ratio was higher in Danish boys and tended to be higher in Danish girls compared to northern living Inuit boys and girls, respectively. These differences were eliminated after adjustment for BF%, aerobic fitness, age and puberty. Conclusions In contrast to our hypothesis, plasma leptin was higher in Danish children despite a more healthy metabolic profile compared to Inuit children. As expected, plasma adiponectin was lowest in Inuit children with the most adverse metabolic profile. PMID:23940841

This cross-sectional study investigated the clinical features of functional constipation (FC) at preschool age, as well as emotional and behavioral characteristics of the children, psychological symptom level and parental attitudes of the mothers, and compared these with that of non-referred typically developing controls with normal intestinal habits. Participants included 65 children with FC (mean age, 43.6 ± 15.4 months; range, 25-72 months), 59 healthy controls (mean age, 46.9 ± 14.5 months; range, 25-72 months) and the mothers of the children. The Childhood Behavior Checklist, Symptom Checklist 90 and Parental Attitude Research Instrument were filled in by the mothers. Participants with FC had higher problem scores than the comparison children in a variety of emotional and behavioral parameters. Approximately half exhibited internalizing and one-third had externalizing problems in the clinical range. The mothers of the patient group had higher levels of psychological distress, overprotective parenting and strict discipline. On multiple logistic regression analysis child psychopathology, maternal education level and maternal distress were independently associated with FC. Behavior problems are common in children with FC from an early age. Low level of education and high psychological distress of the mothers seem to be important risk factors for constipation and should be assessed carefully in the management of these cases. © 2013 Japan Pediatric Society.

[Purpose] The aim of the study was to clarify the effects of regular exercise on lipid profiles and serum adipokines in Korean children. [Subjects and Methods] Subjects were divided into controls (n=10), children who were obese (n=10), and children with type 2 diabetes mellitus (n=10). Maximal oxygen uptake (VO2max), body composition, lipid profiles, glucagon, insulin and adipokines (leptin, resistin, visfatin and retinol binding protein 4) were measured before to and after a 12-week exercise program. [Results] Body weight, body mass index, and percentage body fat were significantly higher in the obese and diabetes groups compared with the control group. Total cholesterol, triglycerides, low-density lipoprotein cholesterol and glycemic control levels were significantly decreased after the exercise program in the obese and diabetes groups, while high-density lipoprotein cholesterol levels were significantly increased. Adipokines were higher in the obese and diabetes groups compared with the control group prior to the exercise program, and were significantly lower following completion. [Conclusion] These results suggest that regular exercise has positive effects on obesity and type 2 diabetes mellitus in Korean children by improving glycemic control and reducing body weight, thereby lowering cardiovascular risk factors and adipokine levels.

To investigate the conflict resolution abilities of children with Specific Language Impairment, and to verify whether the time of speech-language therapy correlates to the performance on the conflict resolution task. Participants included 20 children with Specific Language Impairment (Research Group) and 40 children with normal language development (Control Group), with ages ranging from 7 years to 8 years and 11 months. To assess the conflict resolution abilities, five hypothetical contexts of conflict were presented. The strategies used by the children were classified and scored by the following levels: level 0 (solutions that do not match the other levels), level 1 (physical solutions), level 2 (unilateral solutions), level 3 (cooperative solutions), and level 4 (mutual solutions). Statistical analysis showed group effect for the variable total score. There was a difference between the groups for modal development level, with higher level of modal development observed in the Control Group. There was no correlation between the period of speech-language therapy attendance and the total score. Children with Specific Language Impairment present difficulties in solving problems, in view of the fact that they mainly use physical and unilateral strategies. There was no correlation between the time of speech-language therapy and performance in the task.

In Brazil, there are scarce data on lead (Pb) and cadmium (Cd) contamination, especially for more vulnerable populations such as preschool children. In this paper, we answer two questions: (1) What are the exposure levels of lead and cadmium in preschool children, in Sao Paulo, Brazil? and (2) What are the risk factors associated with this exposure? This cross-sectional study included 50 day care centers (DCCs), totaling 2463 children aged 1-4 years. Venous blood samples were analyzed by ICP-MS. Questionnaires were administered to the parents. Multiple logistic regression models were used to identify associations between blood lead levels (BLLs) and blood cadmium levels (BCLs) and potential risk factors. The geometric mean for BLLs was 2.16 μg/dL (95% CI: 2.10-2.22 μg/dL), and the 97.5th percentile was 13.9 μg/dL (95% CI: 10.0-17.3 μg/dL). For cadmium exposure, the geometric mean for BCLs was 0.48 μg/L (95% CI: 0.47-0.50 μg/L), and the 95th percentile was 2.57 μg/L (95% CI: 2.26-2.75 μg/L). The DCCs' geographic region was associated with high BLLs and BCLs, indicating hot spots for lead and cadmium exposures. In addition, it was found that the higher the vehicles flow, the higher were the BLLs in children. Red lead in household gates was also an important risk factor for lead exposure. Comparing these results with the findings of the Fourth National Report on Human Exposure to Environmental Chemicals by CDC-2013, it was found that in Brazilian preschool children the BLLs are almost three times higher (97.5th percentile) and the BCLs are almost twelve times higher (95th percentile) than those in U.S. children.

The consumption of beverages contributes to diet quality and overall nutrition. Studies on malted drinks, one of the widely consumed beverage choices among children in Asia, however, have received limited attention. This study aimed to examine the prevalence of malted drink consumption and explored associations of sociodemographic characteristics, nutrient intakes, weight status and physical activity levels with malted drink consumption among primary school children in Malaysia. Data for this analysis were from the MyBreakfast Study, a national cross-sectional study conducted from April to October 2013 throughout all regions in Malaysia. A total of 2065 primary school children aged 6 to 12 years were included in the present analysis. Data on two days 24-h dietary recall or record, anthropometry, physical activity and screen time were recorded. Associations between malted drink consumption and related factors were examined using binary logistic regression, adjusting for region, area, gender, ethnicity and household income. Among children aged 6 to 12 years, 73.5% reported consuming malted drinks for at least once per week. Consumption of malted drinks was significantly associated with region (χ(2) = 45.64, p < 0.001), gender (χ(2) = 4.41, p = 0.036) and ethnicity (χ(2) = 13.74, p = 0.008). Malted drink consumers had similar total energy intake but higher micronutrient intakes compared to non-consumers. High physical activity level (OR = 1.77, 95% CI = 1.06, 2.99) and lower screen time during weekends (OR = 0.93, 95% CI = 0.86, 0.99) were independently associated with malted drink consumption among 6 to 9 year-old children, but not among 10 to 12 year-old children. No association was observed between malted drink consumption and weight status. Malted drink consumption is prevalent among Malaysian primary school children, particularly higher among boys, indigenous children and those who lived in the East Coast region of Malaysia. Consuming malted drinks is associated with higher micronutrient intakes and higher levels of physical activity, but not with body weight status.

There is a significant lack of evidence guiding our understanding of the needs of families of children who are deaf/hard of hearing (Deaf/HH) with an autism spectrum disorder (ASD). Much of our current knowledge is founded in case report studies with very small numbers of children with the dual diagnosis. The purpose of this study was to gain an understanding of the factors relating to caregiver stress and needs (i.e., supports and interventions) in families of children who are Deaf/HH with ASD. Comparison groups of families of children who were Deaf/HH, families with a hearing child with ASD, and families of children who were Deaf/HH with ASD were administered standardized questionnaires of stress with brief qualitative questionnaires focusing on family-identified needs. Six families of children with the dual diagnosis, four families of children who were Deaf/HH, and three families of children with ASD. Surveys included demographic and support questionnaires, the Parenting Stress Index (PSI), the Pediatric Hearing Impairment Caregiver Experience, and a qualitative questionnaire. Families of children who were Deaf/HH with ASD had a higher median total stress score on the PSI as compared to families of children who were Deaf/HH only (58.5 versus 41.5, respectively; p = 0.02) and higher Child Domain scores (60 versus 43, respectively; p = 0.02), indicating higher levels of stress in families of children with the dual diagnosis. The families of children who were Deaf/HH with ASD reported similar levels of stress as families of children with ASD. Families of children who are Deaf/HH with an ASD experience stress and describe similar needs and priorities as families of hearing children with ASD. This suggests the needs related to having an autism spectrum disorder are of high priority in families of children with the dual diagnosis. American Academy of Audiology.

The amount of father-child contact after separation is closely linked to the probability that father fulfill their financial obligations towards their children. Determining the factors that encourage this contact is, therefore, crucial to the process of reducing the risk of poverty to which children of separated parents are exposed. Based on data collected from fathers at the 1995 Canadian General Social Survey of the Family, this paper uses multi-level regression analysis to identify factors associated with higher levels of contact between fathers and children, including socio-demographic characteristics of children and fathers, variables associated with attitudes, and fathers' satisfaction with custody and access arrangements.

Children's activity level, including physical activity (PA) and screen sedentary time (SST), is influenced by environmental factors in which parents play a critical role. Different types of parenting styles may influence children's activity level. Inconsistent results were found on the association between parenting styles and PA, and few studies tested the association between parenting styles and SST. This study examined the association between parenting styles, PA and SST and the modifying effect of children's gender and maternal educational level on these associations. Cross-sectional data were collected from parents of children aged 8-11 years old who completed a web-based non-standardized questionnaire (N = 4047). Since 85% of the questionnaires were filled in by mothers, parenting styles are mainly reported by mothers. Multiple linear regression techniques were used to assess the associations between parenting styles (authoritative, permissive, authoritarian and neglectful), and PA and SST (mean min/day). The modifying effect of children's gender and maternal educational level on these associations was explored. P values ≤.0125 were considered as statistically significant based on the Bonferroni correction for four primary analyses. The neglectful parenting style was most widely used (35.3%), while the authoritarian style was least common (14.8%). No significant association was found between parenting styles and PA level. As regards SST, an authoritative parenting style was significantly associated with lower SST in boys while a neglectful parenting style was significantly associated with higher SST in both boys and girls. When the mother had a medium educational level, an authoritative parenting style was significantly associated with lower SST while neglectful parenting was significantly associated with higher SST. No association was found between parenting styles and PA. However, an authoritative parenting style was associated with a reduction in SST and a neglectful parenting style with an increase in SST, especially in boys and in children whose mother had a medium education level. Future studies of parenting practices are needed to gain more insight into the role of parents in children's PA and SST levels, as a basis for the development of interventions tailored to support parents in stimulating PA and reducing SST in children.

The aim of this study was to assess the effect of vegetarian diet on iron metabolism parameters paying special attention to serum hepcidin and soluble transferrin receptor (sTfR) concentrations in 43 prepubertal children (age range 4.5-9.0 years) on vegetarian and in 46 children on omnivorous diets. There were no significant differences according to age, weight, height, and body mass index (BMI) between vegetarian and omnivorous children. Vegetarians had similar intake of iron and vitamin B 12 and a significantly higher intake of vitamin C (p < 0.05) compared with non-vegetarians. Hematologic parameters and serum iron concentrations were within the reference range in both groups of children. Serum transferrin levels were similar in all subjects; however, ferritin concentrations were significantly (p < 0.01) lower in vegetarians than in omnivores. In children on a vegetarian diet, median hepcidin levels were lower (p < 0.05) but sTfR concentrations significantly higher (p < 0.001) compared with omnivorous children. In the multivariate regression model, we observed associations between hepcidin level and ferritin concentration (β = 0.241, p = 0.05) in the whole group of children as well as between hepcidin concentration and CRP level (β = 0.419, p = 0.047) in vegetarians. We did not find significant associations with concentration of sTfR and selected biochemical, anthropometric, and dietary parameters in any of the studied groups of children. As hematologic parameters and iron concentrations in vegetarians and omnivores were comparable and ferritin level was lower in vegetarians, we suggest that inclusion of novel markers, in particular sTfR (not cofounded by inflammation) and hepcidin, can better detect subclinical iron deficiency in children following vegetarian diets.

Variability within the literature investigating typically-developing siblings of children with an autism spectrum disorder suggests that the quality of sibling outcomes may depend on specific factors. For this study, 42 parents of a child with an autism spectrum disorder and a typically- developing sibling provided data via online questionnaires. Birth order rank of the child with an autism spectrum disorder significantly moderated the relation between externalizing behaviors in children with an autism spectrum disorder and externalizing behaviors in their typically-developing siblings. Children with an autism spectrum disorder and higher levels of behavior problems had typically-developing siblings with higher levels of behavior problems only when the child with an autism spectrum disorder was older. These results provide a hint of clarification about the complex nature of sibling relations, but a great deal more research is needed to further examine outcomes of typically-developing siblings of children with an autism spectrum disorder.

The incidence of hypothyroidism is higher among children with Down syndrome than among children in the general population. The frequency of hypothyroidism is higher in the areas of endemic goiter than in other areas. The aim of this paper was to study the concentrations of TSH and FT4 in children with Down syndrome residents of Mérida, a region of Venezuelan Andes. At the Centro de Estudio y Prevención del Retardo Mental y Alteraciones en el Desarrollo (CEPREMAD), the thyroid function was studied in 48 children (1 month to 6 years old), who had Down syndrome, and in 123 healthy children of similar ages. All the children were referred to the Center for thyroid function evaluation. Two (4.2%) of the 48 children with Down syndrome had congenital hypothyroidism and 22 (45.8%) had subclinical hypothyroidism (high concentration of thyrotropin-TSH). Among the control children, only 14% had elevated levels of TSH. There were no differences in relation to the gender. In conclusion in children with Down syndrome, the frequency of high concentrations of TSH was three times higher than the frequency among the healthy children. The frequency of hypothyroidism was similar to that found in areas without endemic goiter.

To evaluate the association between handgrip strength and ideal cardiovascular health (CVH) in Colombian children and adolescents. During the 2014-2015 school years, we examined a cross-sectional component of the FUPRECOL (Association for Muscular Strength with Early Manifestation of Cardiovascular Disease Risk Factors among Colombian Children and Adolescents) study. Participants included 1199 (n = 627 boys) youths from Bogota (Colombia). Handgrip strength was measured with a standard adjustable hand held dynamometer and expressed relative to body mass (handgrip/body mass) and as absolute values in kilograms. Ideal CVH, as defined by the American Heart Association, was determined as meeting ideal levels of the following components: 4 behaviors (smoking status, body mass index, cardiorespiratory fitness, and diet) and 3 factors (total cholesterol, blood pressure, and glucose). Higher levels of handgrip strength (both absolute and relative values) were associated with a higher frequency of ideal CVH metrics in both sexes (P for trend ≤ .001). Also, higher levels of handgrip strength were associated with a greater number of ideal health behaviors (P for trend < .001 in both boys and girls), and with a higher number of ideal health factors in boys (P for trend < .001). Finally, levels of handgrip strength were similar between ideal versus nonideal glucose or total cholesterol groups in girls. Handgrip strength was strongly associated with ideal CVH in Colombian children and adolescents, and thus supports the relevance of early targeted interventions to promote strength adaptation and preservation as part of primordial prevention.

Control programmes generally use a school-based strategy of mass drug administration to reduce morbidity of schistosomiasis and soil-transmitted helminthiasis (STH) in school-aged populations. The success of school-based programmes depends on treatment coverage. The community-directed treatment (ComDT) approach has been implemented in the control of onchocerciasis and lymphatic filariasis in Africa and improves treatment coverage. This study compared the treatment coverage between the ComDT approach and the school-based treatment approach, where non-enrolled school-aged children were invited for treatment, in the control of schistosomiasis and STH among enrolled and non-enrolled school-aged children. Coverage during the first treatment round among enrolled children was similar for the two approaches (ComDT: 80.3% versus school: 82.1%, P=0.072). However, for the non-enrolled children the ComDT approach achieved a significantly higher coverage than the school-based approach (80.0 versus 59.2%, P<0.001). Similar treatment coverage levels were attained at the second treatment round. Again, equal levels of treatment coverage were found between the two approaches for the enrolled school-aged children, while the ComDT approach achieved a significantly higher coverage in the non-enrolled children. The results of this study showed that the ComDT approach can obtain significantly higher treatment coverage among the non-enrolled school-aged children compared to the school-based treatment approach for the control of schistosomiasis and STH.

Reading aloud to children is a valued practice to promote emergent literacy and language skills that form the foundation for future reading success. We conducted a descriptive study of shared book reading practices between caregivers and their children with autism spectrum disorder (n = 17) and caregivers and their typically developing children (n = 20) to identify factors that can promote or inhibit children's engagement in reading. Caregivers and their children read nine books (familiar, non-fiction, fiction). Children with ASD demonstrated lower levels of passive engagement (looking at the book) and higher levels of non-engaged behavior compared to typically developing children. Caregiver reading quality and book type contributed to joint engagement during reading. Implications of these findings for intervention development are discussed.

Increased lactate is an important biochemical marker in diagnosis of children with suspicion of mitochondrial disorders. A diagnostic dilemma may originate if analyses are performed after seizures, when the increased lactate levels may be considered to result from the seizures. To address this problem, we ascertained the diagnostic value of lactate and alanine in blood (B) and cerebrospinal fluid (CSF) in children with mitochondrial disorders (n = 24), epilepsy (n = 32), psychomotor retardation (n = 23), meningitis (n = 12) and meningism (n = 16). Lactate concentration was measured using a spectrophotometric method. Amino acids in serum and CSF were analyzed by ion exchange chromatography with ninhydrin detection. Average blood and CSF-lactate levels were significantly higher in children with mitochondrial disorders (3.87 ± 0.48 and 4.43 ± 0.55 mmol/l) and meningitis (2.77 ± 0.45 and 8.58 ± 1.08 mmol/l) than in children with epilepsy (1.72 ± 0.13 and 1.62 ± 0.04 mmol/l), psychomotor retardation (1.79 ± 1.40 and 1.68 ± 0.06 mmol/l) or meningism (1.70 ± 0.13 and 1.64 ± 0.07 mmol/l). Blood and CSF-alanine levels were also higher in children with mitochondrial disorders (558 ± 44 and 51 ± 8 μmol/l) than in children with epilepsy (327 ± 23 and 27 ± 3 μmol/l) or psychomotor retardation (323 ± 27 and 26 ± 3 μmol/l). The CSF-lactate levels of children with epilepsy were similar whether the samples were obtained 3 ± 0.6 h after an attack of brief seizures or from children without history of recent seizures. Elevated cerebrospinal fluid lactate level is a reliable marker pointing to mitochondrial origin of disease, even in children who have recently suffered short-lasting seizures. Some children with mitochondrial disorders manifest only mild or intermittent elevation of lactate levels. Copyright © 2010 European Paediatric Neurology Society. Published by Elsevier Ltd.

Chromosome 22q11.2 deletion syndrome (22q11.2DS) is a complex developmental disorder with serious medical, cognitive and emotional symptoms across the lifespan. This genetic deletion also imparts a lifetime risk for developing schizophrenia that is 25-30 times that of the general population. The origin of this risk is multifactorial and may include dysregulation of the stress response and immunological systems in relation to brain development. Vitamin D is involved in brain development and neuroprotection, gene transcription, immunological regulation and influences neuronal signal transduction. Low levels of vitamin D are associated with schizophrenia, depression and anxiety in the general population. Yet, little is known about how vitamin D levels in children with 22q11.2DS could mediate risk of psychosis in adulthood. Blood plasma levels of vitamin D were measured in children aged 7-16 years with (n=11) and without (n=16) 22q11.2DS in relation to parent reports of children's anxiety and atypicality. Anxiety and atypicality in childhood are risk indicators for the development of schizophrenia in those with 22q11.2DS and the general population. Children with 22q11.2DS had lower vitamin D levels, as well as elevated anxiety and atypicality compared with typical peers. Higher levels of anxiety, depression and internalizing problems but not atypicality were associated with lower levels of vitamin D. Vitamin D insufficiency may relate to higher levels of anxiety and depression, in turn contributing to the elevated risk of psychosis in this population. Further study is required to determine casual linkages between anxiety, stress, mood and vitamin D in children with 22q11.2DS.

The purpose of this study was to investigate the clinical, laboratory, and pathologic characteristics of dense deposit disease (DDD) in Korean children and to determine whether these characteristics differ between Korean and American children with DDD. In 2010, we sent a structured protocol about DDD to pediatric nephrologists throughout Korea. The data collected were compared with previously published data on 14 American children with DDD. Korean children had lower 24-hr urine protein excretion and higher serum albumin levels than American children. The light microscopic findings revealed that a higher percentage of Korean children had membranoproliferative glomerulonephritis patterns (Korean, 77.8%; American, 28.6%, P = 0.036), whereas a higher percentage of American children had crescents (Korean, 0%; American, 78.6%, P < 0.001). The findings from the electron microscopy revealed that Korean children were more likely to have segmental electron dense deposits in the lamina densa of the glomerular basement membrane (Korean, 100%; American, 28.6%, P = 0.002); mesangial deposit was more frequent in American children (Korean, 66.7%; American, 100%, P = 0.047). The histological findings revealed that Korean children with DDD were more likely to show membranoproliferative glomerulonephritis patterns than American children. The degree of proteinuria and hypoalbuminemia was milder in Korean children than American children. PMID:23091320

The purpose of this study was to examine the level of empathy in deaf and hard of hearing (pre)adolescents compared to normal hearing controls and to define the influence of language and various hearing loss characteristics on the development of empathy. The study group (mean age 11.9 years) consisted of 122 deaf and hard of hearing children (52 children with cochlear implants and 70 children with conventional hearing aids) and 162 normal hearing children. The two groups were compared using self-reports, a parent-report and observation tasks to rate the children's level of empathy, their attendance to others' emotions, emotion recognition, and supportive behavior. Deaf and hard of hearing children reported lower levels of cognitive empathy and prosocial motivation than normal hearing children, regardless of their type of hearing device. The level of emotion recognition was equal in both groups. During observations, deaf and hard of hearing children showed more attention to the emotion evoking events but less supportive behavior compared to their normal hearing peers. Deaf and hard of hearing children attending mainstream education or using oral language show higher levels of cognitive empathy and prosocial motivation than deaf and hard of hearing children who use sign (supported) language or attend special education. However, they are still outperformed by normal hearing children. Deaf and hard of hearing children, especially those in special education, show lower levels of empathy than normal hearing children, which can have consequences for initiating and maintaining relationships.

We investigated the relationship between insulin resistance reflected by homeostasis model assessment (HOMA-IR) index and serum HbA1c levels of obese children. This study included 70 obese and 60 normal weight healthy children between the ages of 3 and 15. Anthropometric measures and biochemical tests (fasting glucose, fasting insulin, HbA1c) were performed on all subjects. Plasma glucose levels were measured by the glucose oxidase method. Plasma insulin concentrations were measured by radioimmunoassay (RIA). HOMA-IR index was used to estimate insulin resistance. A cut-off HOMA-IR level of ≥2.5 was accepted. The HbA1c analysis was performed using high-pressure liquid chromatography. The statistical analysis was performed using SPSS 5. Student's unpaired t-test and the Mann-Whitney U test were used to determine statistical significance. Gender distribution did not reveal significant difference among the obese (F: 48.6%, M: 51.4%) and the non-obese (F: 46.7%, M: 53.3%) groups. The mean age value was significantly higher in the obese group (10.09 ± 3.09) (p > 0.005) than the non-obese group (8.31 ± 3.14) (p < 0.05). The mean value of body mass index (BMI) was 25.55 ± 4.3 in the obese group and 16.63 ± 2.3 in the non-obese group. The mean HOMA-IR values of obese group (2.84 ± 1.77) was significantly higher than the non-obese group (1.50 ± 0.95) (p < 0.005). Insulin resistance was significantly higher in the obese group. Subjects with HOMA-IR ≥2.5 levels in the obese group had significantly higher HbA1c values than those with HOMA-IR <2.5 levels. High HbA1c levels in obese children can be used as a screening tool to detect insulin sensitivity and resistance at an early stage.

This study determined the relationship between anthropometric status of 3-5-year-old urban children and theirs mothers' educational levels and employment status in Rasht City, northern Iran. A total of 1319 children (638 girls and 681 boys) at the ages of 3 and 6 years in all day-care centres in Rasht City were studied, using a cross-sectional design. Height and weight of the children were measured, and data on mothers' educational levels, employment status and duration of any breastfeeding were collected. Height for age, weight for age and weight for height of the children were compared with the National Center for Health Statistics (NCHS) reference population of the United States, and z-values 12 years of schooling, OR = 1.87; 95% CI: 1.08-2.4) had higher relative risk for underweight than children of mothers with an intermediate level of education (5-12 years of schooling). Children of mothers with college education were also more at risk for development of stunting (OR = 1.41; 95% CI: 1.14-4.22). In addition, children of employed mothers were more likely to be underweight (OR = 1.52; 95% CI: 1.05-2.31), stunted (OR = 2.42; 95% CI: 1.21-6.35) and wasted (OR = 3.35; 95% CI: 1.21-5.58) than children of non-employed mothers. The relative risk for undernutrition was higher in the children of both less and highly educated mothers compared with children of mothers with an intermediate level of education. Mothers' employment was also negatively related to nutritional status of these children in day-care centres in Rasht City.

Vitamin D fortification of non-cow's milk beverages is voluntary in North America. The effect of consuming non-cow's milk beverages on serum 25-hydroxyvitamin D levels in children is unclear. We studied the association between non-cow's milk consumption and 25-hydroxyvitamin D levels in healthy preschool-aged children. We also explored whether cow's milk consumption modified this association and analyzed the association between daily non-cow's milk and cow's milk consumption. In this cross-sectional study, we recruited children 1-6 years of age attending routinely scheduled well-child visits. Survey responses, and anthropometric and laboratory measurements were collected. The association between non-cow's milk consumption and 25-hydroxyvitamin D levels was tested using multiple linear regression and logistic regression. Cow's milk consumption was explored as an effect modifier using an interaction term. The association between daily intake of non-cow's milk and cow's milk was explored using multiple linear regression. A total of 2831 children were included. The interaction between non-cow's milk and cow's milk consumption was statistically significant (p = 0.03). Drinking non-cow's milk beverages was associated with a 4.2-nmol/L decrease in 25-hydroxyvitamin D level per 250-mL cup consumed among children who also drank cow's milk (p = 0.008). Children who drank only non-cow's milk were at higher risk of having a 25-hydroxyvitamin D level below 50 nmol/L than children who drank only cow's milk (odds ratio 2.7, 95% confidence interval 1.6 to 4.7). Consumption of non-cow's milk beverages was associated with decreased serum 25-hydroxyvitamin D levels in early childhood. This association was modified by cow's milk consumption, which suggests a trade-off between consumption of cow's milk fortified with higher levels of vitamin D and non-cow's milk with lower vitamin D content. © 2014 Canadian Medical Association or its licensors.

Do maternal ratings of appetite in infants predict later Child Eating Behaviour Questionnaire scores and body mass index?

2010-02-01

In a longitudinal birth cohort maternal ratings of children's appetite made at 6 weeks, 12 months and 5-6 years were correlated with one another and with subscales from the Child Eating Behaviour Questionnaire (CEBQ) at 5-6 years, and body mass index (BMI) at 6-8 years. Statistically significant correlations were found between the children's appetite ratings. Appetite ratings in infancy were also correlated with the CEBQ subscale scores at 5-6 years to a limited extent, but not with the BMI at 6-8 years. The appetite rating at 5-6 years and three of the CEBQ subscales were independently associated with BMI. Children with higher levels of Emotional Over-Eating and Desire to Drink had higher BMIs, and children with higher levels of Satiety Responsiveness had lower BMIs. These results provide further evidence that there are concurrent associations between appetite ratings in childhood and BMI but suggest that appetite ratings in infancy are related only weakly to later appetite measures and do not predict later BMI. 2009 Elsevier Ltd.

To assess the prevalence of small intestinal bacterial overgrowth (SIBO) and methane production in children with encopresis. Radiographic fecal impaction (FI) scores were assessed in children with secondary, retentive encopresis and compared with the breath test results. Breath tests with hypoosmotic lactulose solution were performed in both the study patients (n = 50) and gastrointestinal control subjects (n = 39) groups. The FI scores were significantly higher in the patients with encopresis who were methane producers (P < .01). SIBO was diagnosed in 21 of 50 (42%) patients with encopresis and 9 of 39 (23%) of control subjects (P = .06). Methane was produced in 56% of the patients with encopresis versus 23.1% of the control subjects in the gastrointestinal group (P < .01). Fasting methane level was elevated in 48% versus 10.3 %, respectively (P < .01). Children with FI and encopresis had a higher prevalence of SIBO, elevated basal methane levels, and higher methane production. Methane production was associated with more severe colonic impaction. Further study is needed to determine whether methane production is a primary or secondary factor in the pathogenesis of SIBO and encopresis.

2017-03-01

This study aimed to examine (a) whether mindfulness skills were associated with higher quality of life through lower body shame for treatment-seeking children/adolescents with overweight and obesity and (b) whether this indirect effect was moderated by children/adolescents' age and gender. The sample included 153 children/adolescents with overweight/obesity followed in individual nutrition consultations. Participants completed self-report measures of mindfulness, body shame, and quality of life. Moderated mediation analyses showed that higher levels of mindfulness were associated with better perceived quality of life through lower body shame, but only among girls. For boys, higher levels of body shame did not translate into a poorer perception of quality of life, and the indirect effect of mindfulness on quality of life via lower body shame was not significant. These results suggest that body shame is an important mechanism to explain why mindfulness may help girls with overweight/obesity perceive a better quality of life. Copyright © 2016 Elsevier Ltd.

Background In adults with heart failure, elevated levels of fibroblast growth factor 23 (FGF23) are associated with mortality. Data on FGF23 levels in pediatric heart failure are lacking. Patients and Methods We conducted a cross-sectional study of 17 healthy children (mean age, 13 years) and 20 pediatric patients with heart failure (mean age, 12 years) who underwent echocardiography and the following measurements: plasma FGF23 and parathyroid hormone (PTH); serum phosphate, creatinine and N-terminal prohormone brain natriuretic peptide (NT-proBNP). Symptom severity was assessed with the New York Heart Association (NYHA) and the Ross classification systems. Results Of 20 patients, 11 had dilated cardiomyopathy; 4, congenital heart disease; 3, hypertrophic cardiomyopathy; 1, a failing heart transplant; and 1, pulmonary hypertension. Mean phosphate levels in patients were within the reported reference range for healthy children. Median PTH levels were in the normal range in patients and controls. The median FGF23 level was higher in patients vs. controls (110.9 vs. 66.4 RU/ml, P=0.03) and higher in patients on diuretics vs. other patients (222.4 vs. 82.1 RU/ml, P=0.01). Levels of FGF23 and NT-proBNP were directly correlated (r=0.47, P=0.04), and patients with greater physical functional impairment had higher FGF23 levels (142.5 in those with moderate-severe limitation vs. 92.8 RU/ml in those with no limitation; P=0.05). Among patients with dilated cardiomyopathy, higher FGF23 levels were associated with a greater left ventricular end-diastolic diameter (r=0.63, P=0.04). Conclusion FGF23 levels are elevated in children with heart failure and are associated with diuretic use, severity of heart failure and left ventricular dilation. PMID:23740037

Previous studies suggest that preschoolers from low socioeconomic backgrounds engage in more screen time. Still, the factors in the social and physical home environment driving these differences in preschool children's screen time are poorly understood. This study examines potential home environment mediators in the associations between parental educational level and preschoolers' screen time. A total of 864 children aged 3-6 years and their parents participated in a cross-sectional DAGIS study in 2015-2016. Parents recorded their children's screen time in a diary (N = 823). For the analyses, the daily average screen time at home was calculated. Parental questionnaires (N = 808) assessed educational level and eight social and physical environment factors in the home (i.e., descriptive norm for children's screen time, parental screen use in front of children, parental importance for limiting children's screen time, parental attitude toward societal pressures for children's screen time, access to screens at home, parental self-efficacy for limiting children's screen time, satisfaction of children's screen time, and rules for limiting children's screen time). Parental education was grouped into low, middle, and high education. The associations were tested by conducting mediation analyses adjusted by season and children's sex and age. The significant mediators in the single-mediator models were included in the final multiple-mediator models. Of the potential eight mediators, the following four had a significant indirect association: descriptive norm for children's screen time, parental screen use in front of children, parental importance for limiting children's screen time, and parental attitude toward societal pressures for children's screen time. Parents with high education had lower descriptive norm and used fewer screens in front of children compared to parents with middle or low education, and in turn, these factors were associated with less screen time among children from parents with a higher education level. Parents with high education placed greater importance on limiting children's screen time and felt less societal pressures about children's screen time compared to parents with low education, and in turn, these factors were associated with less screen time among children from parents with a higher education level. Our study recognized multiple modifiable mediators in the associations between parental education and preschool children's screen time. When aiming to diminish socioeconomic status differences in preschool children's screen time, the focus should be on parental role models, attitudes, and norm related to children's screen time.

Existing research has found that parental migration may negatively impact the psychological adjustment of left-behind children. However, limited longitudinal research has examined if and how future orientation (individual protective factor) and social support (contextual protective factor) are associated with the indicators of psychological adjustment (i.e., life satisfaction, school satisfaction, happiness, and loneliness) of left-behind children. In the current longitudinal study, we examined the differences in psychological adjustment between left-behind children and non-left behind children (comparison children) in rural areas, and explored the protective roles of future orientation and social support on the immediate (cross-sectional effects) and subsequent (lagged effects) status of psychological adjustment for both groups of children, respectively. The sample included 897 rural children ( M age = 14.09, SD = 1.40) who participated in two waves of surveys across six months. Among the participants, 227 were left-behind children with two parents migrating, 176 were with one parent migrating, and 485 were comparison children. Results showed that, (1) left-behind children reported lower levels of life satisfaction, school satisfaction, and happiness, as well as a higher level of loneliness in both waves; (2) After controlling for several demographics and characteristics of parental migration among left-behind children, future orientation significantly predicted life satisfaction, school satisfaction, and happiness in both cross-sectional and longitudinal regression models, as well as loneliness in the longitudinal regression analysis. Social support predicted immediate life satisfaction, school satisfaction, and happiness, as well as subsequent school satisfaction. Similar to left-behind children, comparison children who reported higher scores in future orientation, especially future expectation, were likely to have higher scores in most indicators of psychological adjustment measured at the same time and subsequently. However, social support seemed not exhibit as important in the immediate status of psychological adjustment of comparison children as that of left-behind children. Findings, implications, and limitations of the present study were discussed.

Increased levels of Dickkopf-1 are indicative of Wnt/β-catenin downregulation and lower osteoblast signaling in children and adolescents with type 1 diabetes mellitus, contributing to lower bone mineral density.

Higher levels of Dickkopf-1, which is an inhibitor of Wnt/β-catenin bone metabolic pathway, could be indicative of downregulated Wnt system, with possible lower osteoblast activation and higher osteoclast signaling in type 1 diabetes mellitus children and adolescents. Dickkopf-1 could significantly contribute to diabetes osteopathy. Increased fracture risk and elevated Dickkopf-1 levels, which is an inhibitor of Wnt/β-catenin bone metabolic pathway, have been documented in adult patients with type 2 diabetes mellitus (T2D), while no relevant data exist on childhood type 1 diabetes (T1D). Our aim was to study plasma Dickkopf-1 distribution in children and adolescents with T1D and to correlate Dickkopf-1 with metabolic bone markers and bone mineral density (BMD). We evaluated 40 children and adolescents with T1D (mean ± SD age 13.04 ± 3.53 years, T1D duration 5.15 ± 3.33 years) and 40 healthy age-matched and gender-matched controls (age 12.99 ± 3.3 years). Dickkopf-1 and bone metabolic markers were measured, while total body and lumbar spine BMD were evaluated with dual-energy X-ray absorptiometry (DXA). Dickkopf-1 demonstrated a Gaussian distribution, with higher levels in T1D patients (13.56 ± 5.34 vs 11.35 ± 3.76 pmol/L, p = 0.024). Higher values were found in boys and in prepubertal children. Dickkopf-1 correlated positively with osteoprotegerin and fasting glucose in patients, while positive correlation with sclerostin and total soluble receptor activator of nuclear factor-kappaB ligand (s-RANKL) was found in controls. Positive correlations with C-telopeptide cross-links (CTX), osteocalcin, alkaline phosphatase, phosphate, and insulin-like growth factor 1 (IGF1) were documented in both groups. Lumbar spine Z-score was positively associated with Dickkopf-1 in controls, while a negative trend was found in patients. Higher levels of Dickkopf-1 could indicate a downregulated Wnt/β-catenin system with possible lower osteoblast activation and higher osteoclast signaling in T1D children and adolescents. Dickkopf-1 could possibly be a significant contributor of T1D osteopathy. Future therapies could focus on Wnt/β-catenin metabolic pathway.

Children of the closet: a measurement of the anxiety and self-esteem of children raised by a non-disclosed homosexual or bisexual parent.

This research examined whether a parent's non-disclosure of his or her homosexual or bisexual orientation within the family unit negatively affects self-esteem and anxiety in children, as measured in adulthood. Thirty-six subjects indicated that they had not known of their parent's sexual orientation until an average age of sixteen for the children of lesbian or bisexual mothers, and twenty-two for the children of gay or bisexual fathers. This group's scores on the Rosenberg Self-Esteem Scale, the Marlowe Crowne Social Desirabilty Scale and the State-Trait Anxiety Scale were compared to scores obtained by sixty-three participants who did not have a homosexual/bisexual parent. The number of years a secretive environment surrounded the child was measured, as were participants' attitudes about the secret sexual identity. Although the study did not find that adults previously raised with a closeted parent had significantly higher levels of anxiety or lower levels of self-esteem, results indicated that those who had been raised as children with non-disclosed lesbian mothers showed a significantly higher level of self-esteem than participants with heterosexual parents. Implications of the findings for the targeted population are discussed.

Adenotonsillar hypertrophy is the major pathophysiological mechanism underlying obstructive sleep apnea (OSA) and recurrent tonsillitis (RI) in children. The increased expression of various mediators of the inflammatory response in tonsils of OSA patients prompted our hypothesis that the enhanced local and systemic inflammation in OSA children would promote tonsillar proliferation. Mixed cell cultures from tonsils recovered during adenotonsillectomy in children with OSA and RI were established, and proliferative rates were assessed. Cells were also cultured to determine levels of pro-inflammatory cytokines and anti-oxidant protein levels and mRNA expression. Global cell proliferative rates from OSA tonsils were significantly higher than RI (P<0.01), with CD3+, CD4+, and CD8+ cell proliferation being higher in OSA (P<0.05). Moreover, pro-inflammatory cytokines such as TNF-α, IL-6, and IL-1α were highly expressed in OSA-derived tonsils. Furthermore, thioredoxin (TRX), an anti-oxidant protein, was also highly expressed in OSA tonsils at the mRNA and protein levels (p<0.01). Thus, T-cells are in a highly proliferative state in the tonsils of children with OSA, and are associated with increased production of proinflammatory cytokines and TRX, when compared to children with RI.

Flores, Suzielle M; Salum, Giovanni A; Manfro, Gisele G

2014-09-01

The study of the association between specific characteristics of family environments and different types of psychopathology may contribute to our understanding of these complex disorders and ultimately inform therapeutics. To compare the family characteristics of four groups: typically developing children; children with anxiety disorders only; children with externalizing disorders only; and children with both anxiety and externalizing disorders. This study enrolled 115 individuals from the community. Child psychiatrists made psychiatric diagnoses using a structured clinical interview. The Family Environment scale was used to evaluate six domains of family function. The group with both anxiety and externalizing disorders had higher levels of conflict in family environment and lower levels of organization when compared with typically developing children. In addition, internalizing and externalizing symptoms were positively associated with conflict and negatively with organization. Maternal depressive and anxious symptoms were also associated with higher conflict and lower organization scores. An important between-group difference in comorbid cases of anxiety and behavioral disorders suggests that children with this comorbidity are potential candidates for family interventions to address family conflicts and organizational aspects.

Changes in Urinary Phthalate Metabolite Levels Before and After the Phthalate Contamination Event and Identification of Exposure Sources in a Cohort of Taiwanese Children.

In 2011, the Taiwan Food and Drug Administration inadvertently discovered that, for decades, manufacturers had replaced expensive natural emulsifiers in food products with diethylhexyl phthalate (DEHP). We wanted to compare urinary phthalate metabolite levels of children before and after the DEHP food contamination event and identify source(s) of phthalate exposure in addition to the illegal food additives. In the present study, morning urine samples were collected from a cohort of 453 children in 2010 in Taipei. After the DEHP food contamination event, there were 200 cohort children left at follow-up in 2013. The geometric means (GMs) of urinary mono(2-ethyl-5-hydroxyhexyl) phthalate (5OH-MEHP) levels before and after the event were 9.39 and 13.34 µg/g of creatinine, respectively, with no significant difference ( p = 0.093). After the DEHP food contamination event, we found that urinary phthalate metabolite levels were significantly higher in people who frequently consumed microwave-heated food and used fragrance-containing products ( p < 0.05). In addition, children who did not frequently wash hands before eating had significantly higher urinary phthalate metabolite levels than those who did ( p < 0.05). These results demonstrate that urinary phthalate metabolite levels did not decrease after the DEHP food contamination event, thus, other sources must contribute to phthalate exposure in daily life. Public awareness of approaches to reducing phthalate exposure is necessary.

Urinary tract infection (UTI) is a common infection diagnosis in children, and efficient diagnosis and treatment are important to avoid serious complications. In this study we investigated whether urinary levels of neutrophil-derived heparin-binding protein (HBP) can be used as a marker of UTI in children. These results were compared to those of dipstick analysis, interleukin-6 (IL-6) analysis in urine, and bacterial culturing. Seventy-eight children aged 0-18 years with fever and/or symptoms indicating UTI were enrolled in a prospective consecutive study. Urine samples were cultured and analyzed with dipstick, and concentrations of HBP and IL-6 were measured. Fifteen patients were classified as having UTI, 30 patients had fever but were diagnosed with a non-urinary tract infection, and 33 patients had neither UTI nor fever. Using a urine HBP (U-HBP) cut-off level of 32 ng/mL, the sensitivity and specificity for detecting UTI were 93.3 and 90.3 %, respectively. Receiver operating characteristic curves demonstrated that U-HBP levels were a higher specificity indicator of UTI than urine white blood cell counts or urine IL-6 levels; they also showed a higher sensitivity than the results of the urine nitrite test. All patients with significant growth of clinically relevant bacteria had elevated U-HBP levels. The results indicate that rapid analysis of U-HBP can provide helpful guidance in the management of children with suspected UTI.

The use of alternative chemical flame retardants in consumer products is increasing as the result of the phase-out of polybrominated diphenyl ethers. Today, the most commonly detected alternatives in residential furniture include the organophosphate flame retardants (PFRs) and the Firemaster 550® mixture (FM550). Urinary levels of dialkyl and diaryl phosphate esters, and 2-ethylhexyl tetrabromobenzoate (EH-TBB) have been used as biomarkers of human exposure to PFRs and FM550, respectively. In a previous study, we demonstrated that toddlers had significantly higher levels of PFRs relative to their mothers in a cohort from New Jersey; however, it is unclear if there are regional differences in exposure. It is possible that exposure to PFRs may be higher in California relative to other US States due to the California flammability standard, as was seen previously observed for PBDEs. In the current study, we examined urinary levels of PFR metabolites and TBBA in 28 mother-child pairs from California, USA, collected in 2015, and compared them with levels measured in our previous study from New Jersey. Urine samples were extracted using solid-phase extraction and analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS). Diphenyl phosphate (DPHP), isopropyl-phenyl phenyl phosphate (ip-PPP), bis(1,3-dichloro-2propyl) phosphate (BDCIPP) and BCIPHIPP conjugates were detected in 100% of mother and child urine samples, while bis(1-chloro-2-propyl) phosphate (BCIPP), tert-butyl-phenyl phenyl phosphate (tb-PPP) and TBBA were detected in <50% of samples. Interestingly, BCIPHIPP conjugates were detected in 100% of the urine samples, suggesting ubiquitous exposure to the parent compound, tris(1-chloro-2-propyl) phosphate (TCIPP). The current study found significantly higher BDCIPP levels in California toddlers and higher and ip-PPP levels in mothers as compared to the New Jersey cohort, which may be reflective of California’s furniture flammability standard. For example, BDCIPP levels in California children were 2.4 times higher than those in New Jersey children. Consistent with our previous work, the current study showed higher PFR and EH-TBB exposure in children, likely due to increased hand-mouth behavior. Children’s DPHP and BDCIPP levels, on average, were 5.9 times and 15 times those of their mothers. Positive correlations between paired mothers and their children were shown for DPHP and BCIPHIPP conjugates but not BDCIPP or ip-PPP. In the children, several predictors of hand-mouth behavior were associated with BDCIPP, DPHP and ip-PPP urine levels, but no associations were observed with BCIPHIPP conjugates. PMID:27397928

The purpose was to assess associations between body mass index (BMI) and body fat in a multinational sample of 9-11-year-old children. The sample included 7265 children from countries ranging in human development. Total body fat (TBF) and percentage body fat (PBF) were measured with a Tanita SC-240 scale and BMI z-scores (BMIz) and percentiles were computed using reference data from the World Health Organization and the U.S. Centers for Disease Control and Prevention, respectively. Mean PBF at BMIz values of -1, 0 and +1 were estimated using multilevel models. Correlations between BMI and TBF were >0.90 in all countries, and correlations between BMI and PBF ranged from 0.76 to 0.96. Boys from India had higher PBF than boys from several other countries at all levels of BMIz. Kenyan girls had lower levels of PBF than girls from several other countries at all levels of BMIz. Boys and girls from Colombia had higher values of PBF at BMIz=-1, whereas Colombian boys at BMIz 0 and +1 also had higher values of PBF than boys in other countries. Our results show a consistently high correlation between BMI and adiposity in children from countries representing a wide range of human development.

During the last three decades, the Total Fertility Rate (TFR) in Iran has fallen considerably; from 6.5 per woman in 1983 to 1.89 in 2010. This paper analyzes the extent to which economic determinants at the micro and macro levels are associated with the number of children in Iranian households. Household data from the 2010 Household Expenditure and Income Survey (HEIS) is linked to provincial data from the 2010 Iran Multiple-Indicator Demographic and Health Survey (IrMIDHS), the National Census of Population and Housing conducted in 1986, 1996, 2006 and 2011, and the 1985-2010 Iran statistical year books. Fertility is measured as the number of children in each household. A random intercept multilevel Poisson regression function is specified based on a collective model of intra-household bargaining power to investigate potential determinants of the number of children in Iranian households. Ceteris paribus (other things being equal), probability of having more children drops significantly as either real per capita educational expenditure or real total expenditure of each household increase. Both the low- and the high-income households show probabilities of having more children compared to the middle-income households. Living in provinces with either higher average amount of value added of manufacturing establishments or lower average rate of house rent is associated to higher probability of having larger number of children. Higher levels of gender gap indices, resulting in household's wife's limited power over household decision-making, positively affect the probability of having more children. Economic determinants at the micro and macro levels, distribution of intra-household bargaining power between spouses and demographic covariates determined fertility behavior of Iranian households.

Anxious youth typically experience sleep-related difficulties, but little is known about the role children's coping and perceived control over anxiety may play in these relations. We examined children's perceived levels of control over external anxiety-provoking events and internal anxious emotional reactions, as well as two dispositional coping tendencies (avoidant, support-seeking), and whether these were associated with anxious children's (N = 86) presleep arousal. Low perceived control over anxiety was significantly associated with high levels of presleep arousal. For children with low perceived control, higher avoidance was associated with greater presleep arousal, whereas lower avoidance was associated with lower presleep arousal levels. Findings suggest that efforts to avoid stressful life events may contribute to presleep arousal, especially under conditions where anxious arousal seems uncontrollable.

Twenty two children with mixed-infection of tick-borne encephalitis (TBE) and ixodic tick borreliosis (ITB) were studied. Blood hydrocortisone level was changed in 94.5% of the cases. The most significant activation of hydrocortisone secretion in combination with the most pronounced and prolonged general brain manifestations, was detected in infants. Blood hydrocortisone level correlated with clinical symptoms of combined TBE and ITB infections. Along with higher hydrocortisone level, down-regulation of production of antibodies both to B. burgdorferi and to TBE virus was specific for all children studied.

Adverse Childhood Experiences, the Medical Home, and Child Well-Being.

To examine the relationship between adverse childhood experiences (ACE), access to a medical home and a global measure of well-being among children ages 6-17 using the 2011-2012 National Survey of Children's Health. Multivariate linear regressions assessed the associations between each adverse experience and an index of child well-being with and without the impact of other events. The number of ACE was summed for each respondent and the analyses were repeated with the cumulative score as a continuous variable. The cumulative model was repeated with the addition of an interaction term between ACE score and medical home access. All analyses were conducted separately for children ages 6-11 and adolescents 12-17. Over half (53 %) of US children ages 6-17 have experienced some adverse experience during childhood. Over a quarter (28 %) has experienced at least two adverse experiences, while 15 % have experienced three or more hardships. Results suggest that the accumulation of ACE reduces well-being in children. The associations remained significant after controlling for gender, race/ethnicity, age, parental education, special health condition, and medical home access. Medical home access was consistently associated with higher levels of child well-being and was a significant moderator of the relationship between the total ACE and child well-being among children ages 6-11. Children with ACE exposure and access to a medical home have higher levels of well-being than comparable children without access to a medical home. Children exposed to adverse experiences have measurably lower levels of well-being, although younger children with access to a medical home are protected at increasing exposure.

Hepatitis A is endemic in India and mainly causes sporadic infections. However, children in childcare centers, schools and orphanages are vulnerable to common-source outbreaks as they have naive hosts. To investigate hepatitis A outbreak in an orphanage from Pune, India. Monitoring of virus excretion and anti-HAV antibody levels in hepatitis A virus (HAV) infected children. The orphanage housed 93 children of the age 1 month-6.5 years. Analysis of the collected serum (n=78) and stool samples (n=63) revealed 20 children to be either positive for anti-HAV IgM antibodies or excreting HAV, 14 being symptomatic and 6 asymptomatic, while 32 were already anti-HAV IgG positive either due to past HAV exposure (n=7, mean log antibody titers: 2.96) or maternal antibodies (n=25, mean log antibody titers: 1.13). Serum samples, taken 4 weeks apart, did not show any significant difference in the IgM and IgG antibody levels either. However, virus excretion decreased significantly after 15 days in symptomatic children (mean log HAV RNA copies/ml 1.03+0.30), while asymptomatic children continued to excrete higher viral loads, at constant levels (mean log HAV RNA copies/ml 2.33+0.33), for up to 90 days. Though virus excretion continued up to 90 days in all HAV infected children, asymptomatic children excreted higher viral loads for longer period and hence can contribute significantly in person-to-person virus transmission. All children should be vaccinated in such set ups. Copyright © 2015 Elsevier B.V. All rights reserved.

Psychological complaints among children in joint physical custody and other family types: Considering parental factors

Aims: Increasing proportions of Scandinavian children and children in other Western countries live in joint physical custody, moving between parents’ homes when parents live apart. Children and parents in non-intact families are at risk of worse mental health. The potential influence of parental ill-health on child well-being in the context of differing living arrangements has not been studied thoroughly. This study investigates the psychological complaints of children in joint physical custody in comparison to children in sole parental care and nuclear families, while controlling for socioeconomic differences and parental ill-health. Methods: Data were obtained from Statistics Sweden’s yearly Survey of Living Conditions 2007–2011 and child supplements with children 10–18 years, living in households of adult participants. Children in joint physical custody (n=391) were compared with children in sole parental care (n=654) and children in nuclear families (n=3,639), using a scale of psychological complaints as the outcome measure. Results: Multiple regression modelling showed that children in joint physical custody did not report higher levels of psychological complaints than those in nuclear families, while children in sole parental care reported elevated levels of complaints compared with those in joint physical custody. Adding socioeconomic variables and parental ill-health only marginally attenuated the coefficients for the living arrangement groups. Low parental education and parental worry/anxiety were however associated with higher levels of psychological complaints. Conclusions: Psychological complaints were lower among adolescents in joint physical custody than in adolescents in sole parental care. The difference was not explained by parental ill-health or socioeconomic variables. PMID:26553250

Early childhood hemoglobin level is a strong predictor of hemoglobin levels during later childhood among low-income Alaska children.

For unknown reasons, Arctic Indigenous children have iron deficiency and anemia prevalences up to 10 times higher than national reference populations. The current study sought to identify the importance of Alaska Native status, residence and hemoglobin (Hb) level at age 10 to 23 months for predicting Hb levels at age 24 to 59 months when controlling for potential confounders. Retrospective cohort. A birth certificate database was linked to a database containing hemoglobin levels determined through the U.S. Supplemental Nutrition Program for Women, Infants and Children (WIC) among Alaskan children age 10 to 59 months evaluated from 1999-2006. Of children with a birth certificate matched to WIC data, Alaska Native status and residence in western and northern Alaska were associated strongly with anemia at both ages. Nevertheless, of 5,796 children with Hb levels determined at both ages, the single strongest predictor of Hb level at age 24 to 59 months was Hb level at age 10 to 23 months. The community-level anemia prevalence among children age 10 to 23 months was predictive of community-level anemia prevalence among children age 24 to 59 months. The early onset of anemia and the strong association between earlier and later Hb levels or anemia at both the individual and community levels suggest a role for prenatal effects that remain until at least age 5 years. This is true particularly of Yupik and Inupiat children, who make up the primary residents of western and northern Alaska.

The purpose of this study was to examine the prevalence of smoking in a nationally representative sample of Chinese elementary and middle school students and to investigate its risk factors from families and schools. The data were from the National Children's Study of China (NCSC), in which 24,013 fourth- to ninth-grade students were recruited from 100 counties in 31 provinces in China. Chi-square tests and one-way ANOVAs were used to analyze the relationships between smoking and the risk factors. Logistic regressions were used to calculate odds ratios. The prevalence of ever smokers and current smokers were 19.0% and 5.4%. Focusing on current smokers, boys, middle school students, rural students, boarding students, non-only children and those owning parents with low educational levels reported smoking significantly more than girls, elementary school students, urban students, non-boarding students, only children and those owning parents with high educational levels. Lower trust and support from teachers and higher parent-child conflict positively predicted both smoking and smoking frequency. Lower trust and support from classmates was associated with higher possibility of smoking. However, higher trust and support from classmates was associated with higher smoking frequency. Teacher smoking and friend smoking were only predictive of smoking, but not of smoking frequency. Boys, middle school students, rural students, boarding students, non-only children and those owning parents with low educational levels need special attention. The most risk factors for smoking and smoking frequency were lower trust and support from teachers and higher parent-child conflict. Copyright © 2014 Elsevier Ltd. All rights reserved.

Objective To identify the nutritional and immunological correlates of memory and neurocognitive development as measured by the Mullen Scales of Early Learning (MSEL) and by the Color Object Association Test (COAT) among children in Uganda. Design This analysis uses baseline data collected between 2008 and 2010 from 119 HIV-infected children ages 1–6 years participating in a randomized controlled trial of an interventional parenting program in Kayunga, Uganda. Methods Peripheral blood draws were performed to determine immunological biomarkers. Unadjusted and adjusted linear regression models were used to relate MSEL and COAT scores to sociodemographic characteristics, weight-for-age Z-scores (WAZ), antiretroviral therapy (ART) status and immunological biomarkers. Results 111 children were included in the final analysis. Lower levels of CD4+ CD38+ T-cells (p=0.04) were associated to higher Immediate and Total Recall scores (p=0.04). Higher levels of CD8+ HLA-DR+ T-cells were associated with higher Total Recall score (p=0.04) of the COAT. Higher CD4+ CD38+ HLA-DR+ T-cells levels were associated with higher Gross Motor scores of the MSEL (p=0.02). WAZ was positively correlated to Visual Reception, Fine Motor, Expressive Language and composite score of the MSEL. Conclusions Overall, WAZ was a stronger predictor of neurocognitive outcomes assessed by the MSEL. CD4+ CD38+ T-cells were more specifically associated with memory-related outcomes. Future research should include immunological markers and standardized neurocognitive tests to further understand this relationship. PMID:26605506

Interest on the impact of socioeconomic differences on youth's health is growing. The aim of the present study was to examine the association of parental educational level with psychological positive health and health complaints in Spanish children and adolescents. Parental educational level, psychological positive health indicators (perceived health status, life satisfaction, quality of family relationships, quality of peer relationships and academic performance) and health complaint index (headache, stomach ache, backache, feeling low, irritability or bad temper, feeling nervous, difficulties getting to sleep, feeling dizzy) were self-reported using the Health Behavior in School-aged Children questionnaire in 685 (366 boys and 319 girls) children and adolescents. Children reporting parents with non-university studies (father, mother or both) had significantly higher odd ratio of having lower academic performance, lower life satisfaction, perceiving their health status as otherwise (vs. excellent) and having health complaints sometime than their counterparts reporting parents with university studies (father, mother or both). Current results provide evidence that children having parents with a university degree (father, mother or both) are more likely to have higher psychological positive health and lower health complaints than children reporting parents with non-university studies. This is particularly important for the welfare policy that must pay attention for implementing programs for helping population to access to university studies by their impact on youth health. © 2016 John Wiley & Sons Ltd.

Obesity and obstructive sleep apnea syndrome (OSA) are common coexisting conditions associated with a chronic low-grade inflammatory state underlying some of the cognitive, metabolic, and cardiovascular morbidities. To examine the levels of inflammatory markers in obese community-dwelling children with OSA, as compared to no-OSA, and their association with clinical and polysomnographic (PSG) variables. Methods. In this cross-sectional, prospective multicenter study, healthy obese Spanish children (ages 4-15 years) were randomly selected and underwent nocturnal PSG followed by a morning fasting blood draw. Plasma samples were assayed for multiple inflammatory markers. 204 children were enrolled in the study; 75 had OSA, defined by an obstructive respiratory disturbance index (RDI) of 3 events/hour total sleep time (TST). BMI, gender, and age were similar in OSA and no-OSA children. Monocyte chemoattractant protein-1 (MCP-1) and plasminogen activator inhibitor-1 (PAI-1) levels were significantly higher in OSA children, with interleukin-6 concentrations being higher in moderate-severe OSA (i.e., AHI > 5/hrTST; P < 0.01), while MCP-1 levels were associated with more prolonged nocturnal hypercapnia (P < 0.001). IL-6, MCP-1, and PAI-1 are altered in the context of OSA among community-based obese children further reinforcing the proinflammatory effects of sleep disorders such as OSA. This trial is registered with ClinicalTrials.gov NCT01322763.

Understanding physical (in-) activity, overweight, and obesity in childhood: Effects of congruence between physical self-concept and motor competence.

Both the physical self-concept and actual motor competence are important for healthy future physical activity levels and consequently decrease overweight and obesity in childhood. However, children scoring high on motor competence do not necessarily report high levels of physical self-concept and vice versa, resulting in respective (in-) accuracy also referred to as (non-) veridicality. This study examines whether children's accuracy of physical self-concept is a meaningful predictive factor for their future physical activity. Motor competence, physical self-concept and physical activity were assessed in 3 rd grade and one year later in 4 th grade. Children's weight status was categorized based on WHO recommendations. Polynomial regression with Response surface analyses were conducted with a quasi-DIF approach examining moderating weight status effects. Analyses revealed that children with higher motor competence levels and higher self-perceptions show greater physical activity. Importantly, children who perceive their motor competence more accurately (compared to less) show more future physical activity. This effect is strong for underweight and overweight/obese children, but weak for normal weight children. This study indicates that an accurate self-perception of motor competence fosters future physical activity beyond single main effects, respectively. Hence, the promotion of actual motor competence should be linked with the respective development of accurate self-knowledge.

Oxidative stress plays a pivotal role in the pathogenesis of neurological disorders. Free radical generation appears to be the mode of lead toxicity. We evaluated the effects of blood lead levels on oxidative stress parameters in children suffering from neurological disorders. Thirty children (aged 3-12 years) with neurological disorders (cerebral palsy [n = 12], seizures [n = 11], and encephalopathy [n = 7]) were recruited in the study group. Sixty healthy children (aged 3-12 years) from similar socio-economic environments and not suffering from any chronic disease were taken as the controls. Blood lead levels and oxidant/antioxidant status were determined. Mean blood lead level was significantly higher while delta-aminolevulinic acid dehydratase (delta-ALAD) activity, a biomarker for lead exposure, was significantly lower in the study group as compared to the control group (P < 0.05 for each). Malondialdehyde (MDA) levels, an end-product of lipid peroxidation, were significantly higher while the antioxidant glutathione (GSH) levels were significantly lower in the study group as compared to the control group (P < 0.05 for each). Activities of the antioxidant enzymes superoxide dismutase (SOD) and catalase (CAT) were significantly higher in the study group than those of the control group (P < 0.05 for each). There were significant negative correlations of blood lead levels with delta-ALAD (r = -0.35; P < 0.05) and GSH (r = -0.31; P < 0.05), and positive correlations with MDA (r = 0.37; P < 0.05), SOD (r = 0.53; P < 0.05), and CAT (r = 0.31; P < 0.05). In turn, delta-ALAD had significant negative correlations with MDA (r = -0.29; P < 0.05), SOD (r = -0.28; P < 0.05) and CAT (r = -0.34; P < 0.05), but positive correlation with GSH (r = 0.32; P < 0.05). Although a causal pathway can not be determined from the present study, our findings indicate lead-induced oxidative stress in blood of children with neurological disorders. Lead-induced oxidative stress as an underlying mechanism for neurological diseases in children warranted further investigation.

Selenium (Se) is an essential micronutrient that exerts multiple functions in the organism, and both its deficiency and excess can cause health impairments. Thus, it is important to monitor its levels in the population, especially in vulnerable groups, such as children from the Brazilian Amazon region, where there is a lack of information in this regard. The aim of this research was to study Se levels in the whole blood of children and teenagers (5-16 years old) from two riparian communities at the Madeira River (Cuniã RESEX and Belmont). Se level variations related to the communities' location, seasonality, diet, and body mass index (BMI) were assessed. Blood samples were collected in both communities for Se determinations, using ICP-MS and hemogram analyses, during May and September of 2011. Food frequency questionnaires were applied to assess consumption rates of specific food items. Non-parametric tests and linear multiple regressions were applied in the data analyses. Median Se levels were significantly higher during May (Cuniã RESEX 149 μg L -1 ; Belmont 85 μg L -1 ) compared to September (Cuniã RESEX 79 μg L -1 ; Belmont 53 μg L -1 ). No significant differences were found between the communities regarding BMI measurements and anemia prevalence. However, Se blood levels were significantly higher at the Cuniã RESEX compared to Belmont. In addition, the former showed higher fish and Brazil nut intakes, which may be the main Se sources for this community. These results contribute to a better understanding of Se reference levels for children and teenagers of Western Amazon riparian communities.

Objective To study the state of peripheral T lymphocytes and cytokine levels in children with epilepsy. Methods Twenty children with epilepsy and 20 healthy age-matched children were recruited and their peripheral blood was collected. The activation of T lymphocytes was evaluated by detecting the expressions of CD25, CD69 and cytotoxic T lymphocyte-assicated antigen 4 (CTLA4). The function of T lymphocytes was evaluated by detecting the expressions of interferon γ (IFN-γ), tumor necrosis factor α (TNF-α), IL-17A and IL-6. The activation of regulatory T cells (Tregs) was evaluated by detecting the expression of IL-10. Results Children with epilepsy had higher expressions of CD25, CD69 and CTLA-4 in T lymphocytes than the controls did. The expressions of IFN-γ, TNF-α, IL-17A and IL-6 in T lymphocytes of children with epilepsy were higher than those of the controls. Frequency of Tregs producing IL-10 was higher in children with epilepsy as compared with the controls. Conclusion Peripheral T lymphocytes of children with epilepsy are activated and produce cytokines.

The purpose of this study was to test a conceptual model predicting children's anxiety/depression in middle childhood in a community sample of children with parents who had alcohol problems (n = 112) and those without alcohol problems (n = 101). The conceptual model examined the role of parents' alcohol diagnoses, depression, and antisocial behavior among parents of children ages 12 months to kindergarten age in predicting marital aggression and parental aggravation. Higher levels of marital aggression and parental aggravation were hypothesized to predict children's depression/anxiety within time (18 months to kindergarten age and, prospectively, to age during fourth grade). The sample was recruited from New York State birth records when the children were 12 months old. Assessments were conducted at 12, 18, 24, and 36 months; at kindergarten age; and during fourth grade. Children with alcoholic fathers had higher depression/anxiety scores according to parental reports but not self-reports. Structural equations modeling was largely supportive of the conceptual model. Fathers' alcoholism was associated with higher child anxiety via greater levels of marital aggression among families with alcohol problems. Results also indicated that there was a significant indirect association between parents' depression symptoms and child anxiety via marital aggression. The results highlight the nested nature of risk characteristics in alcoholic families and the important role of marital aggression in predicting children's anxiety/depression. Interventions targeting both parents' alcohol problems and associated marital aggression are likely to provide the dual benefits of improving family interactions and lowering risk of children's internalizing behavior problems.

The oral health of children with disability is often not as good as that of other children. In view of improving their oral health, this study aims to explore the utilization of fluoride varnish services among children with disability in Taiwan and its relevant influencing factors. With children under the age of 5 as subjects, this study is conducted based on the database of Ministry of the Interior, Executive Yuan, ROC in 2008, coupled with information gathered between 2006 and 2008 on preventive health care and health insurance from the Bureau of Health Promotion and the National Health Research Institute, respectively. In addition to descriptive statistics and bivariate analysis, this study examined the factors determining the use of fluoride varnish with logistic regression analysis. Research revealed that fluoride varnish is used by up to 9.84% of children with disability; the use increases with age and decreases with increased level of disability, but is remarkably higher in those with catastrophic illness/injury. The probability of fluoride varnish use is lower among those living in areas of lower urbanization (levels 5-7) and higher among those whose parents have higher premium-based monthly salaries. Recommendations include (1) providing a differential pricing scheme for fluoride varnish based on the level of disability of the child, (2) promoting proactively among dentists to carry out regular fluoride varnish in rural areas and collaboration with pediatricians to provide convenient services and (3) targeting families in low socioeconomic brackets, improving knowledge of fluoride varnish.

Heavy metal lead (Pb) and cadmium (Cd) are widespread environmental contaminants and exert detrimental effects on the immune system. We evaluated the association between Pb/Cd exposures and innate immune cells in children from an electronic waste (e-waste) recycling area. A total number of 294 preschool children were recruited, including 153 children from Guiyu (e-waste exposed group), and 141 from Haojiang (reference group). Pb and Cd levels in peripheral blood were measured by graphite furnace atomic absorption spectrophotometer, NK cell percentages were detected by flow cytometer, and other innate immune cells including monocytes, eosinophils, neutrophils and basophils were immediately measured by automated hematology analyzer. Results showed children in Guiyu had significantly higher Pb and Cd levels than in reference group. Absolute counts of monocytes, eosinophils, neutrophils and basophils, as well as percentages of eosinophils and neutrophils were significantly higher in the Guiyu group. In contrast, NK cell percentages were significantly lower in Guiyu group. Pb elicited significant escalation in counts of monocytes, eosinophils and basophils, as well as percentages of monocytes, but decline in percentages of neutrophils in different quintiles with respect to the first quintile of Pb concentrations. Cd induced significant increase in counts and percentages of neutrophils in the highest quintile compared with the first quintile of Cd concentrations. We concluded alteration of the number and percentage of innate immune cells are linked to higher levels of Pb and Cd, which indicates Pb and Cd exposures might affect the innate and adaptive immune response in Guiyu children.

Background Most studies of indoor allergens have focused on the home environment. However, schools may be an important site of allergen exposure for children with asthma. We compared school allergen exposure to home exposure in a cohort of children with asthma. Correlations between settled dust and airborne allergen levels in classrooms were examined. Methods Settled dust and airborne samples from 12 inner-city schools were analyzed for indoor allergens using multiplex array technology (MARIA). School samples were linked to students with asthma enrolled in the School Inner-City Asthma Study (SICAS). Settled dust samples from students’ bedrooms were analyzed similarly. Results From schools, 229 settled dust and 197 airborne samples were obtained. From homes, 118 settled dust samples were obtained. Linear mixed regression models of log-transformed variables showed significantly higher settled dust levels of mouse, cat and dog allergens in schools than homes (545% higher for Mus m 1, estimated absolute difference 0.55 μg/g, p<0.0001; 198% higher for Fel d 1, estimated absolute difference 0.13 μg/g, p=0.0033; and 144% higher for Can f 1, estimated absolute difference 0.05 μg/g, p=0.0008). Airborne and settled dust Mus m 1 levels in classrooms were moderately correlated (r=0.48; p< 0.0001). There were undetectable to very low levels of cockroach and dust mite allergens in both homes and schools. Conclusions Mouse allergen levels in schools were substantial. In general, cat and dog allergen levels were low, but detectable, and were higher in schools. Aerosolization of mouse allergen in classrooms may be a significant exposure for students. Further studies are needed to evaluate the effect of indoor allergen exposure in schools on asthma morbidity in students with asthma. PMID:22672325

Group-based social hierarchies exist in nearly every society, yet little is known about whether children understand that they exist. The present studies investigated whether 3- to 10-year-old children (N=84) in South Africa associate higher-status racial groups with higher levels of wealth, one indicator of social status. Children matched higher-value belongings with White people more often than with multiracial or Black people and with multiracial people more often than with Black people, thus showing sensitivity to the de facto racial hierarchy in their society. There were no age-related changes in children’s tendency to associate racial groups with wealth differences. The implications of these results are discussed in light of the general tendency for people to legitimize and perpetuate the status quo. PMID:22860510
