  1. Young Children's Improvisations: A Longitudinal Study.

    ERIC Educational Resources Information Center

    Flohr, John W.

    The purpose of this study was to characterize the behavior of 2-, 3-, 4-, and 5-year-old children engaged in improvisational musical tasks. Ten subjects from each of the four age levels participated in the 4-year investigation, which lasted until the 2-year-olds reached 5 years of age. Children met individually with the investigator for 15 minutes…

  2. Emotion recognition by children with Down syndrome: a longitudinal study.

    Pochon, Régis; Declercq, Christelle

    2013-12-01

    According to the literature, children with Down syndrome (DS) have difficulties recognising facial expressions. Yet abilities to recognise emotional expressions are often assessed in tasks that imply comprehension of words for emotions. We investigated the development of these abilities in children with DS in a longitudinal study that did not involve lexical knowledge of emotions. Children with DS and nonspecific intellectual disability and typically developing children matched for developmental age (DA) were assessed once a year over 3 years. They were asked to recognise the facial expression of an emotion after hearing a vocalisation. In each annual session, children with DS were not significantly different from others at recognising emotions. Their abilities to discriminate basic emotions improved significantly and to a similar extent to those of other children. The findings indicate that children with DS develop emotion recognition abilities similarly to other children of the same DA.

  3. Eye dominance in children: a longitudinal study.

    Dellatolas, G; Curt, F; Dargent-Paré, C; De Agostini, M

    1998-05-01

    In a sample of 807 normal preschool children aged from 3 to 6, examined eye dominance was not associated with the declared eye dominance of their parents. Forty percent of the children showed left-eyedness. Eyedness was associated with handedness and not significantly related to age group or sex. A strong relationship between the answers of the two parents concerning eye preference was observed. Two hundred forty-four children were followed-up for 2 years. The examinations were carried out once every 6 months. Two thirds of the children showed perfect stability in eye dominance. There was some evidence that stability in eye use tends to increase with age and to be lower in left-handed children with left-handed parents. There is, at present, very little evidence of a positive association between eye dominance in parents and that in their children.

  4. Longitudinal study of spatial working memory development in young children.

    This study longitudinally compared activity in the frontal cortex during a spatial working memory task between 5-year-old and 7-year-old children using near-infrared spectroscopy. Eight children participated in this study twice, once at 5 years and once at 7 years of age. Behavioral analysis showed that older children performed the working memory task more precisely and more rapidly than younger children. Near-infrared spectroscopy analysis showed that right hemisphere dominance was observed in older children, whereas no hemispheric difference was apparent in younger children. Children with strengthened lateralization showed improved performance from 5 to 7 years. We therefore offer the first demonstration of the developmental changes in frontal cortical activation during spatial working memory tasks during the preschool period.

  5. A longitudinal study of children with developmental dysphasia.

    This study reports longitudinal follow-up of 300 children with developmental dysphasia. Their expressive disturbances are a manifestation of their auditory decoding impairment. These children were investigated on battery of tests of spoken language, of phonological processing and of different audiometric procedures, in order to register all the information necessary to be able judge the speech-language development. The tests focused on diagnosis of central auditory disorder, confirmed the difficulties in association area in children with developmental dysphasia. In speech perception, the temporal processing is one of the functions necessary for the discrimination of phonemes, and of similar words. Our results confirmed long-term problems of children with developmental dysphasia with central auditory perception disorder.

    2012-01-01

    Objective Children with unilateral hearing loss (UHL) have been found to have lower language scores, and increased rate of speech therapy, grade failures, or needing Individualized Education Plans (IEPs). The objective of this study was to determine whether language skills and educational performance improved or worsened over time in a cohort of children with UHL. Study Design Prospective longitudinal cohort study Methods Forty-six children with permanent UHL, ages 6 to 12 years, were studied using standardized cognitive, achievement, and language testing at yearly intervals for three years. Using standardized test scores allowed implicit comparison to norms established by national cross-sectional samples. Secondary outcomes included behavioral issues, IEPs, receipt of speech therapy, or teacher report of problems at school. Analysis utilized repeated measures ANOVA and multilevel random regression modeling. Results Several cognitive and language mean standardized scores increased over time. Possible predictors of increase with time included higher baseline cognitive levels and receipt of interventions through an IEP. However, standardized achievement scores and indicators of school performance did not show concomitant improvements. Rates of IEPs remained > 50% throughout, and rates of speech therapy were consistently about 20%. Conclusions Children with UHL demonstrated improvement in oral language and verbal IQ scores over time, but not improvements in school performance. Parents and teachers reported persistent behavioral problems and academic weaknesses or areas of concern in about 25%. The provision of IEPs for children with UHL, and acknowledging UHL as a hearing disability, may be an effective intervention to improve language skills over time. PMID:22865630

    Objective: To establish the mental health needs of homeless children and families before and after rehousing. Design: Cross sectional, longitudinal study. Setting: City of Birmingham. Subjects: 58 rehoused families with 103 children aged 2-16 years and 21 comparison families of low socioeconomic status in stable housing, with 54 children. Main outcome measures: Children’s mental health problems and level of communication; mothers’ mental health problems and social support one year after rehousing. Results: Mental health problems remained significantly higher in rehoused mothers and their children than in the comparison group (mothers 26% v 5%, P=0.04; children 39% v 11%, P=0.0003). Homeless mothers continued to have significantly less social support at follow up. Mothers with a history of abuse and poor social integration were more likely to have children with persistent mental health problems. Conclusions: Homeless families have a high level of complex needs that cannot be met by conventional health services and arrangements. Local strategies for rapid rehousing into permanent accommodation, effective social support and health care for parents and children, and protection from violence and intimidation should be developed and implemented. Key messages Homeless children and their mothers have a high level of mental health problems Homeless families experience many risk factors, such as domestic violence, abuse, and family and social disruption In two fifths of children and a quarter of mothers, mental health problems persisted after rehousing In contrast with a comparison group of families of low socioeconomic status, a substantial proportion of homeless families remained residentially and socially unstable PMID:9552837

    1985-05-01

    This study is a longitudinal comparison of the health of children exposed to markedly different concentrations of sulfur dioxide and moderately different concentrations of particulate sulfate. The four groups of subjects lived in two areas of one smelter town and in two other towns, one of which was also a smelter town. In the area of highest pollution, children were intermittently exposed to high SO/sub 2/ levels (peak three-hour average concentration exceeded 2,500 micrograms/m3) and moderate particulate SO/sub 4/= levels (average concentration was 10.1 micrograms/m3). When the children were grouped by the four gradients of pollution observed, the prevalence of cough (measured by questionnaire) correlated significantly with pollution levels (trend chi-square = 5.6, p = 0.02). No significant differences in the incidence of cough or other symptoms occurred among the groups of subjects over three years, and pulmonary function and lung function growth over the study were roughly equal among all the groups. These results suggest that intermittent elevations in SO/sub 2/ concentration, in the presence of moderate particulate SO/sub 4/= concentration, produced evidence of bronchial irritation in the subjects, but no chronic effect on lung function or lung function growth was detected.

    2014-02-01

    Ecologically realistic, spontaneous, adult-directed, longitudinal speech data of young children were described by acoustic analyses. The first 2 formant frequencies of vowels produced by 6 children from different American English dialect regions were analyzed from ages 18 to 48 months. The vowels were from largely conversational contexts and were classified according to dictionary pronunciation. Within-subject formant frequency variability remained relatively constant for the span of ages studied. It was often difficult to detect overall decreases in the first 2 formant frequencies between ages 30 and 48 months. A study of the movement of the corner vowels with respect to the vowel centroid showed that the shape of the vowel space remained qualitatively constant from 30 through 48 months. The shape of the vowel space is established early in life. Some aspects of regional dialect were observed in some of the subjects at 42 months of age. The present study adds to the existing data on the development of vowel spaces by describing ecologically realistic speech.

    2012-02-01

    Few researchers have longitudinally examined families caring for technology-dependent children at home. We tested a theoretically and empirically based conceptual model by examining family functioning and normalization in 82 mothers (female primary caregivers) twice over 12 months. Time 1 and Time 2 cross-sectional findings were consistent; the only predictor of family functioning was mothers' depressive symptoms. Contrary to the proposed model, normalization, caregiving duration, and home nursing hours were not directly related to family functioning. Baseline family functioning significantly predicted future family functioning. Also, mothers whose children were no longer technology-dependent at Time 2 reported significant improvements in family functioning and normalization. An intervention to address high levels of depressive symptoms of these mothers is essential to optimizing family functioning.

    This study investigated whether the longitudinal changes in symptom severity in children with autism spectrum disorder (ASD) are associated with changes in the parents׳ autistic traits. The results demonstrated two significant correlations between the changes in children׳s Social Responsiveness Scale (SRS) scores and the Social Responsiveness Scale (SRS) score changes in either the father or both parents. Autistic symptom mitigation in ASD children was associated with increased empathy levels in their parents. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Longitudinal standards for height and height velocity are essential to monitor for appropriate linear growth. We aimed to construct standards in Korean children and adolescents through the population-based longitudinal Kangwha study. Our study was a part of a community-based prospective cohort study from 1986 to 1999 with 800 school children. Height and height velocity were recorded annually from age 6 until final height. Results were compared with cross-sectional data from the 2007 Korean National Growth Charts. Final height was 173.5 cm in boys and 160.5 cm in girls. Although final height was similar between longitudinal and cross-sectional standards, the mean height for age was higher in the longitudinal standard by 1-4 cm from age 6 until the completion of puberty. Using the longitudinal standard, age at peak height velocity (PHV) was 12 in boys and 10 in girls; height velocity at PHV was 8.62 cm/yr in boys and 7.07 cm/yr in girls. The mean height velocity was less than 1 cm/yr at age 17 in boys and 15 in girls. Thus, we have presented the first report of longitudinal standards for height and height velocity in Korean children and adolescents by analyzing longitudinal data from the Kangwha cohort.

    Recent studies have shown evidence of positive concurrent relationships between children's use of text message abbreviations ('textisms') and performance on standardized assessments of reading and spelling. This study aimed to determine the direction of this association. One hundred and nineteen children aged between 8 and 12 years were assessed on measures of general ability, reading, spelling, rapid phonological retrieval, and phonological awareness at the beginning and end of an academic year. The children were also asked to provide a sample of the text messages that they sent over a 2-day period. These messages were analyzed to determine the extent to which textisms were used. It was found that textism use at the beginning of the academic year was able to predict unique variance in spelling performance at the end of the academic year after controlling for age, verbal IQ, phonological awareness, and spelling ability at the beginning of the year. When the analysis was reversed, reading and spelling ability were unable to predict unique variance in textism usage. These data suggest that there is some evidence of a causal contribution of textism usage to spelling performance in children aged 8-12 years. However, when the measure of rapid phonological retrieval (rapid picture naming) was controlled in the analysis, the relationship between textism use and spelling ability just failed to reach statistical significance, suggesting that phonological access skills may mediate some of the relationship between textism use and spelling performance. ©2011 The British Psychological Society.

  8. Mothers' teaching strategies and children's effortful control: a longitudinal study.

    Findings on the relation of maternal verbal teaching strategies to children's effortful control (EC; i.e., self-regulation) are limited in quantity and somewhat inconsistent. In this study, children's EC was assessed at 18, 30, and 42 months (ns = 255, 229, and 209, respectively) with adults' reports and a behavioral measure. Mothers' verbal teaching strategies were assessed while the mother and child worked on a task together. Children's general vocabulary also was measured. In a structural panel model taking into account prior levels of constructs and correlations within time, as well as the relations of EC and teaching strategies to children's vocabulary, socioeconomic status, age, and sex of the child, 18-month EC positively predicted mothers' 30-month cognitive assistance and questioning strategies and negatively predicted 30-month maternal directive strategies. In addition, high 30-month EC predicted greater 42-month maternal cognitive assistance and fewer directive strategies. Thus, mothers' teaching strategies were predicted by individual differences in self-regulatory skills, supporting potential evocative child effects on mothers' teaching strategies.

    The purpose of this study was to establish the reproducibility of a series of anthropometric measures performed twice during one week during a three year period in boys and girls. The subjects of this investigation were 39 children (21 boys and 18 girls), 9-10 year of age at the beginning of the study. Children were measured three times with one year interval. Children were classified by Tanner stage 1-2 during the first measurements, stage 1-3 during the second measurements and stage 1-4 during the third measurements. Body height and weight were measured and BMI calculated. All anthropometric parameters were measured according to the protocol recommended by the International Society for the Advancement of Kinanthropometry (Norton & Olds 1996). Nine skinfolds, 13 girths, eight lengths and eight breadths/lengths were measured. The reproducibility of body height (r = 0.995-0.999), body weight (r = 0.990-0.999) and BMI (r = 0.969-0.999) was very high in boys and girls. The intraclass correlations (ICC), technical errors (TE) and coefficients of variation (CV) were quite different depending on the measurement site of the skinfold thickness. It was surprising that the ICCs were highest and TEs and CVs were lowest during the second year of the measurement. The computed ICC was high, and TE and CV values were quite similar and relatively low in girth, length and breadth/length measurements. It was concluded that the reproducibility of girths, lengths and breadths/lengths in children is very high and the reproducibility of skinfolds is high. Specifically, the reproducibility is very high immediately before puberty in boys and girls.

    Shame and guilt are self-conscious emotions that begin to develop early in life and are associated with various forms of psychopathology. However, little is known about the factors that contribute to these emotions in young children. Specifically, no longitudinal studies to date have examined a range of parent factors that shape the expression of children's shame and guilt. The current multimethod, longitudinal study sought to determine whether parenting style, parental psychopathology, and parents' marital satisfaction assessed when children were age 3 predict expressions of shame and guilt in children at age 6. A large community sample of families (N = 446; 87.4% Caucasian) with 3-year-old children (45.7% female) was recruited through commercial mailing lists. Parent variables were assessed when children were age 3 with mother- and father-report questionnaires and a diagnostic interview. Children's expressions of shame and guilt were observed in the laboratory at age 6. Fathers', but not mothers', history of depression and permissive parenting assessed when children were age 3 predicted children's expressions of shame and guilt when children were age 6; parents' marital dissatisfaction also predicted children's shame and guilt. These findings suggest that parents, and fathers in particular, contribute to expressions of self-conscious emotions in children. These data on emotional development may be useful for better characterizing the risk and developmental pathways of psychopathology.

    2010-04-01

    To assess longitudinally the relations between four parenting styles (authoritative, authoritarian, uninvolved, and indulgent) and child weight status in Mexican American families. Sixty-nine low-income Mexican American mothers and their 4- to 8-year-old children participated in a 4-year longitudinal study. Mothers completed demographic and parenting measures. Children's body weight and height were assessed annually. Body mass index was calculated to determine weight status. At baseline, 65% of children were found to be normal weight, 14% were overweight, and 21% were obese. Analyses examined how parenting styles at baseline predicted child's weight status 3 years later, controlling for initial weight status. Children of indulgent mothers were more likely to become overweight 3 years later than children of authoritative or authoritarian mothers. This study provides longitudinal evidence for the role of indulgent parenting in predicting overweight in Mexican American children. Possible mediating factors that may account for this relationship (e.g., dietary patterns, physical activity patterns, and children's self-regulation) are considered.

    2013-01-01

    Experiencing sexual abuse increases the risk that children will report or otherwise demonstrate problems with emotion, behavior, and health. This longitudinal study of 44 children who experienced sexual abuse examined whether information processing as assessed via the Rorschach Inkblot Test was associated with child-reported depression symptoms assessed via the Children's Depression Inventory (Kovacs, 1992) concurrently and an average of 15 months later. Children whose Rorschach protocols were relatively free of scores suggesting intense distress, complex processing, and sexual content were more likely to experience remission of depression symptoms at follow-up. Findings provide incremental validity for certain Rorschach indexes to inform prognosis regarding depression symptoms and perhaps their treatment.

    Objective The aim of this study was to examine longitudinal patterns of growth trajectories in children of women with eating disorders (ED): anorexia nervosa (AN) and bulimia nervosa (BN). Design Prospective longitudinal birth cohort; Avon Longitudinal Study of Parents and Children (ALSPAC). Setting South West England, UK. Participants The sample consisted of women and their children (n=10 190) from ALSPAC. Patterns of growth among children of women reporting a history of AN (n=137), BN (n=165), both AN and BN (n=68) and other psychiatric disorders (n=920) were compared with an unexposed group of children (n=8900). Main outcome measures Height and weight data, from birth to 10 years, were extracted from health visitor records, parental report from questionnaires and clinic attendances. Growth trajectories were analysed using mixed-effects models and constructed separately for male and female children. Results Between birth and 10 years, male children of women with BN were taller than children in the unexposed group. Male children of women with a history of AN and BN, and female children of women with AN, were shorter throughout childhood. Between the ages of 2 and 5, higher body mass index (BMI) was observed in male children in all maternal ED groups. Conversely, female children of women with AN had a BMI of −0.35 kg/m2 lower at 2 years compared with the unexposed group, with catch-up by age 10. Conclusions Early childhood growth has been found to predict weight gain in adolescence and adulthood, and may be a risk factor for the development of an ED. These findings therefore have public health implications in relation to the prevention of weight-related and eating-related disorders later in life. PMID:24674996

    Attention-Deficit/Hyperactivity Disorder (ADHD) affects approximately 5% of children worldwide and results in significant impairments in daily functioning. Few community-ascertained samples of children with ADHD have been studied prospectively to identify factors associated with differential outcomes. The Children's Attention Project is the first such study in Australia, examining the mental health, social, academic and quality of life outcomes for children with diagnostically-confirmed ADHD compared to non-ADHD controls. The study aims to map the course of ADHD symptoms over time and to identify risk and protective factors associated with differential outcomes. The sample for this prospective longitudinal study is being recruited across 43 socio-economically diverse primary schools across Melbourne, Australia. All children in Grade 1, the second year of formal schooling (6-8 years), are screened for ADHD symptoms using independent parent and teacher reports on the Conners' 3 ADHD index (~N = 5260). Children screening positive for ADHD by both parent and teacher report, and a matched sample (gender, school) screening negative, are invited to participate in the longitudinal study. At baseline this involves parent completion of the NIMH Diagnostic Interview Schedule for Children IV (DISC-IV) to confirm likely ADHD diagnostic status and identify other mental health difficulties, direct child assessments (cognitive, academic, language and executive functioning; height and weight) and questionnaires for parents and teachers assessing outcomes, as well as a broad range of risk and protective factors (child, parent/family, teacher/school, and socio-economic factors). Families will be initially followed up for 3 years. This study is the first Australian longitudinal study of children with ADHD and one of the first community-based longitudinal studies of diagnostically confirmed children with ADHD. The study's examination of a broad range of risk and protective factors and

    ALSPAC (The Avon Longitudinal Study of Parents and Children, formerly the Avon Longitudinal Study of Pregnancy and Childhood) was specifically designed to determine ways in which the individual's genotype combines with environmental pressures to influence health and development. To date, there are comprehensive data on approximately 10,000 children and their parents, from early pregnancy until the children are aged between 8 and 9. The study aims to continue to collect detailed data on the children as they go through puberty noting, in particular, changes in anthropometry, attitudes and behaviour, fitness and other cardiovascular risk factors, bone mineralisation, allergic symptoms and mental health. The study started early during pregnancy and collected very detailed data from the mother and her partner before the child was born. This not only provided accurate data on concurrent features, especially medication, symptoms, diet and lifestyle, attitudes and behaviour, social and environmental features, but was unbiased by parental knowledge of any problems that the child might develop. From the time of the child's birth many different aspects of the child's environment have been monitored and a wide range of phenotypic data collected. By virtue of being based in one geographic area, linkage to medical and educational records is relatively simple, and hands-on assessments of children and parents using local facilities has the advantage of high quality control. The comprehensiveness of the ALSPAC approach with a total population sample unselected by disease status, and the availability of parental genotypes, provides an adequate sample for statistical analysis and for avoiding spurious results. The study has an open policy in regard to collaboration within strict confidentiality rules.

    The objective of this study was to investigate the development and tracking of nutritional status, body composition and physical fitness, and the longitudinal relationship of changes in nutritional status, and body composition with changes in physical fitness over a 1-year period of follow-up. Studied were 380 boys and 322 girls aged 7-14 years from the Ellisras Longitudinal Study. Boys and girls were divided into two groups of pre-adolescence (<11 years) and adolescence (>10 years). High tracking coefficients (>8) were found for nutritional status, body mass index, and fat-free mass, while low tracking coefficients (<4) were found for the sum of skinfolds, fat mass, arm muscle area, and central fat distribution. Moderate and low tracking coefficients were found for the physical fitness items. Longitudinal regression analyses showed that physical fitness performances that require a high energy flux over a short period of time are affected by muscle wasting, whereas having a low body weight appears to be important for a good performance on other fitness items in these malnourished rural South African children.

    Indigenous Australians experience profound levels of disadvantage in health, living standards, life expectancy, education and employment, particularly in comparison with non-Indigenous Australians. Very little information is available about the healthy development of Australian Indigenous children; the Longitudinal Study of Indigenous Children (LSIC) is designed to fill this knowledge gap. This dataset provides an opportunity to follow the development of up to 1759 Indigenous children. LSIC conducts annual face-to-face interviews with children (aged 0.5–2 and 3.5–5 years at baseline in 2008) and their caregivers. This represents between 5% and 10% of the total population of Indigenous children in these age groups, including families of varied socioeconomic and cultural backgrounds. Study topics include: the physical, social and emotional well-being of children and their caregivers; language; culture; parenting; and early childhood education. LSIC is a shared resource, formed in partnership with communities; its data are readily accessible through the Australian Government Department of Social Services (see http://dss.gov.au/lsic for data and access arrangements). As one of very few longitudinal studies of Indigenous children, and the only national one, LSIC will enable an understanding of Indigenous children from a wide range of environments and cultures. Findings from LSIC form part of a growing infrastructure from which to understand Indigenous child health. PMID:25011454

    Objective Research using normative and high-risk samples indicates a significant link between problems with self-regulation and child maladjustment. Nevertheless, little is known about the processes that may modify the link between self-regulation and maladjustment. This longitudinal study examined the joint contributions of child self-regulation and positive parenting behaviors to the development of externalizing and internalizing symptomatology spanning from preschool to 1st grade. Methods Data were collected on a total of 95 physically abused children (58% boys); our longitudinal analyses involved 43 children at Time 1 (preschool), 63 children at Time 2 (kindergarten), and 54 children at Time 3 (1st grade). Children's self-regulation was measured by parent report, and their externalizing and internalizing symptomatology was evaluated by teachers. Parents completed self-report measures of positive parenting. Results Our structural equation modeling analyses revealed positive parenting as a protective factor that attenuated the concurrent association between low self-regulation and externalizing symptomatology among physically abused children. Our findings regarding longitudinal changes in children's externalizing symptomatology supported the differential susceptibility hypothesis: Physically abused children who were at greater risk due to low levels of self-regulation were more susceptible to the beneficial effects of positive parenting, compared to those with high levels of self-regulation. Conclusions Findings suggest that although physical abuse presents formidable challenges that interfere with the development of adaptive self-regulation, positive parenting behaviors may ameliorate the detrimental effects of maladaptive self-regulation on the development of externalizing symptomatology. In addition, the positive and negative effects of caregiving behaviors were more prominent among physically abused children at great risk due to low self-regulation. Practice

    The effects of video games on children's psychosocial development remain the focus of debate. At two timepoints, 1 year apart, 194 children (7.27-11.43 years old; male = 98) reported their gaming frequency, and their tendencies to play violent video games, and to game (a) cooperatively and (b) competitively; likewise, parents reported their children's psychosocial health. Gaming at time one was associated with increases in emotion problems. Violent gaming was not associated with psychosocial changes. Cooperative gaming was not associated with changes in prosocial behavior. Finally, competitive gaming was associated with decreases in prosocial behavior, but only among children who played video games with high frequency. Thus, gaming frequency was related to increases in internalizing but not externalizing, attention, or peer problems, violent gaming was not associated with increases in externalizing problems, and for children playing approximately 8 h or more per week, frequent competitive gaming may be a risk factor for decreasing prosocial behavior. We argue that replication is needed and that future research should better distinguish between different forms of gaming for more nuanced and generalizable insight.

    In this longitudinal study, we examined the stability of the association between executive functions and externalizing behavior problems, and the developmental change of executive functions in a predominately clinically diagnosed preschool sample (N = 200). Inhibition and working memory performance were assessed three times in 18 months. Across time, poorer inhibition performance in young children was associated with attention deficit hyperactivity disorder (ADHD) and disruptive behavior disorders (DBD), and poorer working memory performance was associated with ADHD. Inhibition and working memory performance increased over time, especially in the early preschool period. The improvement of inhibition performance was more pronounced in the clinically diagnosed children compared to the TD children.

    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.

    To explore the different developmental trajectories of social-communicative skills in children with autism and typically developing infants, two longitudinal studies were conducted. In Study 1, we examined the developmental sequence of social-communicative skills in 26 typically developing infants when they were 9 months old and reexamined them when they were 12 and 15 months old. The results indicated a reliable developmental sequence of social-communicative skills in infants with typical development. In Study 2, we explored the emergence sequence of social-communicative skills of 23 children with autism and 23 children with developmental delay between the ages of 2 and 4 years. The results demonstrated that the developmental sequence of social-communicative skills in young children with autism and children with developmental delays was different.

    This research aimed to explore the relation between syntactic awareness and writing composition in 129 Hong Kong Chinese children. These children were from a ten-year longitudinal project. At each year, a number of measures were administered. The 129 children's data of nonverbal reasoning at age 4, phonological awareness, morphological awareness, vocabulary knowledge at age 8, reading comprehension at age 12 and syntactic awareness and writing composition skills at ages 11 and 12 were included in this study. Syntactic awareness was longitudinally and uniquely predictive of Chinese children's writing composition, and children's performance in early writing composition was uniquely associated with their later syntactic skills, even when controlling for the contributions from age, nonverbal and verbal abilities, phonological awareness, and morphological awareness. The relationship between syntactic awareness and writing composition was mediated by children's performance in reading comprehension. These findings may suggest a reciprocal relation between syntactic awareness and writing composition, and this association may vary with ability in reading comprehension in Chinese children.

    This longitudinal study examined the acquisition of early knowledge of astronomy to determine whether children's knowledge at any point in time is consistent with a naive "mental model." Children were first assessed by means of open questions and drawing tasks at 2 and 3 years of age (N=143). The knowledge was reassessed over the course of the following 3 years. The results showed that although a few indications of naive mental models were found, in most cases young children's knowledge was fragmented and accurate knowledge was often expressed alongside inaccurate/synthetic ideas. Furthermore, it was shown that children need to know scientific facts before they start taking the global perspective when describing the world and, when faced with ambiguous open questions, children often experience difficulties that can induce them to change the types of answers they provide.

    A 1-year longitudinal study with three testing points was conducted with 215 British Asian children aged 5 to 11 years to test hypotheses from Berry's acculturation framework. Using age-appropriate measures of acculturation attitudes and psychosocial outcomes, it was found that (a) children generally favored an "integrationist" attitude, and this was more pronounced among older (8-10 years) than in younger (5-7 years) children and (b) temporal changes in social self-esteem and peer acceptance were associated with different acculturation attitudes held initially, as shown by latent growth curve analyses. However, a supplementary time-lagged regression analysis revealed that children's earlier "integrationist" attitudes may be associated with more emotional symptoms (based on teachers' ratings) 6 months later. The implications of these different outcomes of children's acculturation attitudes are discussed.

    This article presents the findings of the final phase of a 5-year longitudinal study with 168 middle- and upper middle-class children in which the complex relations among early home literacy experiences, subsequent receptive language and emergent literacy skills, and reading achievement were examined. Results showed that children's exposure to books was related to the development of vocabulary and listening comprehension skills, and that these language skills were directly related to children's reading in grade 3. In contrast, parent involvement in teaching children about reading and writing words was related to the development of early literacy skills. Early literacy skills directly predicted word reading at the end of grade 1 and indirectly predicted reading in grade 3. Word reading at the end of grade 1 predicted reading comprehension in grade 3. Thus, the various pathways that lead to fluent reading have their roots in different aspects of children's early experiences.

    The purpose of this study was to elucidate the association between children's behavior (i.e., prosocial and problematic behavior) and the parenting style (i.e., laxness and overreactivity) of their caregivers by using longitudinal data in the Japanese population. These data were collected when the children were 7.5 and 9 years. We proposed three hypotheses: children's behavior at 7.5 years will predict their behavior at 9 years; children's behavior at 7.5 years will predict the parenting of their caregivers; and the parenting style of caregivers will affect their children's behavior at 9 years. We evaluated children's behavior and parenting behavior using a strength and difficulties questionnaire and a parenting scale. The hypotheses were tested using structural equation modeling (SEM). The results of the SEM showed that children's behavior at 7.5 years predicted their behavior at 9 years. Children's problematic behavior at 7.5 years triggered overreactive parenting in their caregivers at 9 years, which increased problematic behavior and decreased prosocial behavior in the children at 9 years. These findings indicate the association between children's behavior and the parenting style of caregivers in Japan.

    Changes in body height throughout extended historic periods are very complex and dynamic processes. This pilot study aimed to investigate the pattern of longitudinal height z-scores changes in children before and after entering kindergarten. In summer 2016, we measured height and weight of 32 children from 4 groups of two kindergartens aged 3-6 years. All ages were centered according to the age of entry into the kindergarten. For each child we determined mean z-scores for height before and after entering the kindergarten, and assessed the variances for each kindergarten group. Twenty-two children targeted in height z-scores towards average height of their respective kindergarten group, 10 children did not. Due to the small numbers, the convergence in height variance however, remained insignificant (chi-squared independence test, p = 0.127). Additional studies with larger sample sizes are needed to confirm this pilot study.

    Introduction Our aim was to compare the longitudinal lung function growth of Mexican children and adolescents with the collated spirometric reference proposed for international use and with that of Mexican-Americans from the National Health State Examination Survey III (NHANES) III study. Materials and Methods A cohort of Mexican children in third year of primary school was followed with spirometry twice a year through secondary school. Multilevel mixed-effects lineal models separated by gender were fit for the spirometric variables of 2,641 respiratory-healthy Mexican children expressed as Z-scores of tested reference equations. Impact of adjustment by sitting height on differences with Mexican-American children was observed in a subsample of 1,987 children. Results At same gender, age, and height, Mexican children had increasingly higher forced expiratory volume in 1 s (FEV1) and Forced vital capacity (FVC) than the children from the collated reference study (mean Z-score, 0.68 for FEV1 and 0.51 for FVC) and than Mexican-American children (Z-score, 0.23 for FEV1 and 0.21 for FVC) respectively. Differences with Mexican-Americans were not reduced by adjusting by sitting height. Conclusions For reasons that remain unclear, the gender-, age-, and height-adjusted lung function of children from Mexico City is higher than that reported by several international studies.

    2006-11-01

    The aim of this investigation was to study the effects of prolonged breast- or bottle-feeding on dental caries in Japanese infants. This longitudinal study was conducted by means of a questionnaire and clinical examination of 592 children at 18 months, 2 years and 3 years of age. The children were divided into three groups: 1) children still being breast-fed at 18 months of age (n=42); 2) children still being bottle-fed at 18 months of age (n=45); and 3) children weaned off of breast- or bottle-feeding and with no nonnutritive-sucking habits at 18 months of age (n=205). Results showed that breast-feeding at 18 months of age produced many significant differences to the control children, including a higher prevalence of caries and higher number of dft. However, no significant differences were observed between bottle-fed and control children. In conclusion, our results suggest that prolonged breast-feeding at an early age before primary dentition has fully erupted is a risk factor for dental caries. Therefore, breast-fed children need to be monitored more closely, and aggressive methods of preventive care need to be instituted. It is also important to identify factors related to dental caries among breastfed children as soon as possible, and develop effective preventive programs.

    2015-08-01

    This study examined the causal relationships between assertiveness and both internal and external adjustment in children. Elementary school children in grades four through six (N = 284) participated in the study, which used a short-term longitudinal design. The children completed questionnaires twice during a 6-months period. They responded to assertiveness questionnaires that included two components: "self-expression" and "consideration of others". They also completed a self-esteem scale as an index of internal adjustment, and the Class Life Satisfaction scale as an index of external adjustment. There was a positive causative relationship between "self-expression" and internal adjustment and between "consideration for others" and external adjustment. In addition, the effects on adjustment varied according to the type of assertiveness. Cluster analysis and MANOVA indicated that the group with high "self-expression" and "consideration for others" had high internal and external adjustment, while the children with poor assertiveness showed the lowest degree of adaptivity.

    Nightmares are defined as dreams with strong negative emotions which awaken the dreamer and are common during childhood: cross-sectional data shows the highest prevalence rates between the ages of five and ten. The present longitudinal study was designed to study the stability of nightmares over the course of 2 years. Sleep questionnaires and Strengths and Difficulties Questionnaires were completed by 851 10-years-old children and their parents, separately. In the total sample, nightmares occurred often in 2.5% (parental estimates) to 3.5% (self estimates of the children). The findings indicate that nightmare stability is considerably high, i.e., nightmare occurrence was predicted by the prevalence the year before (in addition to the concurrent amount of emotional symptoms). Children with 'chronic' nightmares showed more psychopathological symptoms. It would be interesting to follow-up these children in order to investigate whether childhood nightmares are also predictive for adult psychopathology.

    2008-02-01

    To determine the rate of appearance of nevi in a cohort of children between ages 6 and 12 years. The number of nevi has been established as the strongest known risk factor for melanoma, but whether the rate at which nevi appear during childhood varies by age is not well understood. The study involved analysis of nevus development over time in a cohort of 640 Western Australian school children who formed the control group in the Kidskin intervention trial. Children were assessed at ages 6, 10 and 12 years, with nevi on the back counted from photographs. The changes in both number and density of nevi between ages 6 and 12 years were linear with respect to age. The number and density of nevi increased at a greater rate for boys compared with girls; for children with blue, hazel and green eyes compared with those with brown eyes; for blonde versus dark haired children and for children with heavy freckling compared with those with no freckles. In conclusion, further research is needed to determine whether the linear increase in nevi continues into adolescence. If so, it suggests that skin cancer prevention campaigns should target older children and adolescents as well as younger children. Longitudinal studies have important advantages over cross-sectional studies in the description of nevus development with age, and should be the preferred study design.

    To test whether school, neighborhood, and family factors are independently associated with children's involvement in bullying, over and above their own behaviors that may increase their risk for becoming involved in bullying. We examined bullying in the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative 1994-1995 birth cohort of 2,232 children. We used mother and teacher reports to identify children who experienced bullying between the ages of 5 and 7 years either as victims, bullies, or bully-victims. We collected information about school characteristics from the Department for Children, Schools and Families. We collected reports from mothers about children's neighborhood and home environments and reports from mothers and teachers about children's internalizing and externalizing problems when they were 5 years old. Multinomial logistic regressions showed that over and above other socioenvironmental factors and children's behavior problems, school size was associated with an increased risk for being a victim of bullying, problems with neighbors was associated with an increased risk for being a bully-victim, and family factors (e.g., child maltreatment, domestic violence) were associated with all groups of children involved in bullying. Socioenvironmental factors are associated with children's risk for becoming involved in bullying over and above their own behaviors. Intervention programs aimed at reducing bullying should extend their focus beyond schools to include local communities and families.

    Previous studies showed an association between viewing of smoking in movies and initiation of smoking among adolescents. However, all studies except one were cross-sectional, and none updated movie smoking exposure prospectively or assessed its influence on children. We enrolled elementary school students, 9 to 12 years of age, in a longitudinal study to assess the influence of movie smoking exposure on smoking initiation among children. Movie smoking content was coded for the most popular movie releases; exposure was assessed by asking children which movies they had seen, on the basis of unique lists of 50 movies sampled randomly from top box office hits and video rentals. Data collection occurred in 3 waves (the baseline survey and 2 follow-up surveys), approximately 1 year apart. Movie lists were updated for each data collection wave, to reflect recent releases. Movie smoking exposure was analyzed in relation to smoking initiation by the end of the study period. Approximately 80% of the children's smoking exposure occurred through movies rated G, PG, or PG-13. Children's movie smoking exposure predicted smoking initiation significantly, after adjustment for multiple covariates including child and parent characteristics. The relative risks were 1.09, 1.09, and 1.07 for a 1-decile increase of movie smoking exposure measured at the baseline, second, and third data collection waves, respectively. The adjusted attributable risk of smoking initiation attributable to movie smoking exposure was 0.35. Our study, which is the first to enroll children in elementary school and to update movie smoking exposure longitudinally, indicates that early exposure has as much influence on smoking risk as does exposure nearer the outcome. Overall, movie smoking may be responsible for at least one third of smoking initiation for children in this age group.

    Publications from the Avon Longitudinal Study of Parents and Children that used empirically derived dietary patterns were reviewed. The relationships of dietary patterns with socioeconomic background and childhood development were examined. Diet was assessed using food frequency questionnaires and food records. Three statistical methods were used: principal components analysis, cluster analysis, and reduced rank regression. Throughout childhood, children and parents have similar dietary patterns. The "health-conscious" and "traditional" patterns were associated with high intakes of fruits and/or vegetables and better nutrient profiles than the "processed" patterns. There was evidence of tracking in childhood diet, with the "health-conscious" patterns tracking most strongly, followed by the "processed" pattern. An "energy-dense, low-fiber, high-fat" dietary pattern was extracted using reduced rank regression; high scores on this pattern were associated with increasing adiposity. Maternal education was a strong determinant of pattern score or cluster membership; low educational attainment was associated with higher scores on processed, energy-dense patterns in both parents and children. The Avon Longitudinal Study of Parents and Children has provided unique insights into the value of empirically derived dietary patterns and has demonstrated that they are a useful tool in nutritional epidemiology.

    Sturge-Weber syndrome is often accompanied by seizures and neurocognitive deterioration, although previous studies have suggested that early functional brain reorganization may diminish the cognitive sequelae in some children with unilateral Sturge-Weber syndrome. The "rules" governing these plasticity mechanisms are poorly understood. In this study, we evaluated longitudinal changes of cognitive functioning (intelligence quotient [IQ]) and assessed the performance of clinical, electroencephalography (EEG), and magnetic resonance imaging (MRI) variables for predicting IQ in children with Sturge-Weber syndrome. Thirty-three young children (mean age: 3.3 years at baseline) with unilateral Sturge-Weber syndrome underwent MRI, scalp EEG, and neuropsychology evaluation twice, with a median follow-up of 2 years. None of the children had epilepsy surgery. Longitudinal IQ changes were calculated. Seizure variables, interictal EEG abnormalities, and extent and location of MRI brain involvement were correlated with IQ assessed at follow-up. Global IQ showed a highly variable course with both increases and decreases over time. Lower IQ at baseline was associated with interval IQ increase. In univariate analyses, lower outcome IQ was associated with baseline EEG abnormalities (P < 0.001), young age at seizure onset (P = 0.001), high seizure frequency (P = 0.02), and early frontal-lobe involvement on MRI (P = 0.01). In multivariate analysis, EEG abnormalities at baseline remained a robust, independent predictor of outcome IQ. The early trajectory of cognitive changes in children with unilateral Sturge-Weber syndrome is highly variable; children with improving IQ likely undergo effective unimpeded functional reorganization. Early onset, frequent seizures, and interictal epileptiform abnormalities on EEG likely interfere with this process resulting in poor cognitive functions. Future studies assessing interventions should target this high-risk subgroup to optimize

    A sample of children, initially 12 years old, in the People's Republic of China participated in this 2-year longitudinal study. Data on parental warmth, control, and indulgence were collected from children's self-reports. Information concerning social, academic, and psychological adjustment was obtained from multiple sources. The results indicated that parenting styles might be a function of child gender and change with age. Regression analyses revealed that parenting styles of fathers and mothers predicted different outcomes. Whereas maternal warmth had significant contributions to the prediction of emotional adjustment, paternal warmth significantly predicted later social and school achievement. It was also found that paternal, but not maternal, indulgence significantly predicted children's adjustment difficulties. The contributions of the parenting variables might be moderated by the child's initial conditions.

    The majority of bilingual speech research has focused on simultaneous bilinguals. Yet, in immigrant communities, children are often initially exposed to their family language (L1), before becoming gradually immersed in the host country's language (L2). This is typically referred to as sequential bilingualism. Using a longitudinal design, this study explored the perception and production of the English voicing contrast in 55 children (40 Sylheti-English sequential bilinguals and 15 English monolinguals). Children were tested twice: when they were in nursery (52-month-olds) and 1 year later. Sequential bilinguals' perception and production of English plosives were initially driven by their experience with their L1, but after starting school, changed to match that of their monolingual peers.

    There is some evidence of a relationship between psychosocial health and the incidence of ear infections and hearing problems in young children. There is however little longitudinal evidence investigating this relationship. This paper used 6-year prospective longitudinal data to examine the impact of ear infection and hearing problems on psychosocial outcomes in two cohorts of children (one cohort recruited at 0/1 years and the other at 4/5 years). Data from the Longitudinal Study of Australian Children (LSAC) were analysed to address the research aim. The LSAC follows two cohorts of children (infants aged 0/1 years - B cohort, n = 4242; and children aged 4/5 years - K cohort, n = 4169) collecting data in 2004, 2006, 2008 and 2010. In B cohort at baseline 3.7% (n = 189) of the sample were reported by their parent to have had an ear infection (excluding hearing problems) and 0.5% (n = 26) were reported by their parent to have hearing problems (excluding ear infections). 6.7% (n = 323) of the K cohort were identified as having had an ear infection and 2.0% (n = 93) to have hearing problems. Psychosocial outcomes were measured using the Strengths and Difficulties Questionnaire. Data were analysed using multivariate analysis of variance and logistic regression, reporting adjusted odds ratio and 95% confidence intervals of the association between reported ear infections (excluding hearing problems)/or hearing problems (excluding ear infections) and psychosocial outcomes. Children were more likely to have abnormal/borderline psychosocial outcomes at 10/11 years of age if they had been reported to have ongoing ear infections or hearing problems when they were 4/5 years old. When looking at the younger cohort however, poorer psychosocial outcomes were only documented at 6/7 years for children reported to have hearing problems at 0/1 years, not for those who were reported to have ongoing ear infections. This study adds further evidence that a relationship may exist between

    This study examined the prevalence and chronicity of sleep problems in children who manifest problems believed to be typical of Autism Spectrum Disorders (ASD). Using data from a longitudinal total population study, symptoms of ASD, insomnia and potential explanatory factors were assessed at ages 7-9 and 11-13. Children were included in a group defined as having Autism Spectrum Problems (ASP) if they scored above a strict threshold on the Autism Spectrum Screening Questionnaire (ASSQ). Twenty-eight (0.8%) of 3700 children fulfilled the selected criteria for ASP at both waves, and the prevalence of chronic insomnia was more than ten times higher in these children compared to the controls. Children with ASP developed more sleep problems over time, with an incidence rate at wave 2 of 37.5% compared to 8.6% in the controls. The sleep problems were more persistent over time, with a remission rate of 8.3% compared to 52.4% in the controls. ASP was a strong predictor of sleep problems at wave 2 (OR = 12.44), and while emotional and behavioural problems explained a large proportion of this association, the effect of ASP on insomnia remained significant in the fully adjusted model (OR = 3.25). These findings call for increased awareness of sleep problems in children with ASP.

    All publications covering diet during pregnancy that stemmed from the Avon Longitudinal Study of Parents and Children were reviewed. Diet was assessed using a food frequency questionnaire. Socioeconomic background, maternal mental health, and the health and development of the offspring were assessed using a variety of methods, such as direct measurement, self-completion questionnaires, and assays of biological samples. Differences in diet, including specific food and nutrient intakes and dietary patterns, were associated with maternal educational attainment, smoking habits, and financial difficulty. There were marginal intakes, compared with recommendations, of the key nutrients iron, magnesium, potassium, and folate. Maternal diet during pregnancy was predictive of offspring diet during childhood. There were independent associations between prenatal fish consumption and lower frequency of maternal depressive and anxiety symptoms, as well as lower frequency of intrauterine growth retardation. Consistent evidence that fish consumption during pregnancy benefited the neurocognitive development of the child was also found. Two constituents of fish, n-3 polyunsaturated fatty acids and iodine, were associated with these benefits in children. The findings from the Avon Longitudinal Study of Parents and Children strengthen the recommendation to eat fish regularly during pregnancy. PMID:26395341

    Stress and depression can affect an individual's level of physical activity and fitness, which may place them at risk of developing cardiovascular disease. This study investigates the longitudinal effects of stress and depression on physical activity and cardiorespiratory fitness among youth. Six hundred and seventy-six children, initially aged 8 years, from the LOOK study completed a modified version of the Children's Depression Inventory, the Children's Stress Questionnaire, and objective physical activity and cardiorespiratory fitness assessments on three occasions, every 4 years. Depressive symptoms had a direct effect (longitudinal) on the cardiorespiratory fitness of girls, with a similar trend for boys. In cross-sectional analyses, a child who identified with more symptoms of depression and stress was likely to be less fit and less physically active, which in girls extended to less moderate-to-vigorous physical activity. Our findings, that both physical activity and fitness are impacted by depression and stress may contribute to strategies directed towards achieving enhanced physical activity and reductions in obesity.

    The impact of childhood epilepsy can only be appreciated by understanding that epilepsy comprises a set of complex neurobehavioral conditions with significant social consequences, and not simply disorders of recurrent seizures. Our objective is to describe the hypotheses and methodology behind a large prospective longitudinal study that is based on a conceptual framework for understanding health outcomes. The study will quantify the specific influences--direct, mediating or moderating--that various epilepsy, comorbid, child, and family variables exert on health over the early life course. The target population is 8- to 14-year-old children with epilepsy and their caregivers from across Canada. Children, caregivers, and health professionals are completing 17 measures at five visits over a 28-month period. We have selected measures based on content, the source of the items, psychometric properties, and provisions for child self-report. Our cross-sectional and longitudinal design includes a relational model for structural equation modeling of specific biomedical and psychosocial variables with hierarchical direction of influence. To measure change over time, we will use hierarchical linear modeling. This article reports the framework for interpreting future data. We believe that it will help researchers consider their methodology and encourage them to plan and execute longitudinal studies. Furthermore, the article will help clinical readers identify what to look for when evaluating outcomes research. It is our belief that the next generation of research to understand life-course effect in the lives of children and youth with chronic conditions and their families must occur over real time.

  17. A prospective, longitudinal study of growth, nutrition and sedentary behaviour in young children with cerebral palsy

    PubMed Central

    2010-01-01

    Background Cerebral palsy is the most common cause of physical disability in childhood, occurring in one in 500 children. It is caused by a static brain lesion in the neonatal period leading to a range of activity limitations. Oral motor and swallowing dysfunction, poor nutritional status and poor growth are reported frequently in young children with cerebral palsy and may impact detrimentally on physical and cognitive development, health care utilisation, participation and quality of life in later childhood. The impact of modifiable factors (dietary intake and physical activity) on growth, nutritional status, and body composition (taking into account motor severity) in this population is poorly understood. This study aims to investigate the relationship between a range of factors - linear growth, body composition, oral motor and feeding dysfunction, dietary intake, and time spent sedentary (adjusting for motor severity) - and health outcomes, health care utilisation, participation and quality of life in young children with cerebral palsy (from corrected age of 18 months to 5 years). Design/Methods This prospective, longitudinal, population-based study aims to recruit a total of 240 young children with cerebral palsy born in Queensland, Australia between 1st September 2006 and 31st December 2009 (80 from each birth year). Data collection will occur at three time points for each child: 17 - 25 months corrected age, 36 ± 1 months and 60 ± 1 months. Outcomes to be assessed include linear growth, body weight, body composition, dietary intake, oral motor function and feeding ability, time spent sedentary, participation, medical resource use and quality of life. Discussion This protocol describes a study that will provide the first longitudinal description of the relationship between functional attainment and modifiable lifestyle factors (dietary intake and habitual time spent sedentary) and their impact on the growth, body composition and nutritional status of young

    To evaluate hearing outcome, to characterize the nature of symptomatic and asymptomatic congenital cytomegalovirus (cCMV) infection and associated hearing loss, and to compare results with data from previous studies. A prospective multicenter registry was set up in 2007. Six centers participated in the development of a standardized protocol for diagnosis, treatment, and follow-up. Data were gathered in an online registry. Children (n = 379) with a documented cCMV infection and at least 2 separate audiologic evaluations were included. Audiometric results from a multicenter cohort study of children with cCMV infection with longitudinal observation were examined. Results from 123 children with a symptomatic and 256 children with an asymptomatic cCMV infection were analyzed. In the group with symptomatic cCMV, 63% had hearing loss, compared with 8% in the group with asymptomatic cCMV. Delayed-onset hearing loss occurred in 10.6% of symptomatic cCMV and in 7.8% of asymptomatic cCMV. In the group with symptomatic cCMV, 29.3% of children used some kind of hearing amplification; 1.6% in the group with asymptomatic cCMV used hearing amplification. Symptomatic and asymptomatic cCMV infections are a major cause of hearing loss in childhood. Reliable estimates of the long-term outcome of cCMV infection are mandatory to increase vigilance, especially among pregnant women and to draw attention to preventive measures, vaccine development, and prenatal and postnatal therapy. Universal screening of newborns for cCMV infection should be initiated and combined with longitudinal audiometric follow-up. Copyright © 2016 Elsevier Inc. All rights reserved.

    Many children are not physically active enough for a health benefit. One avenue of physical activity is modified sport programs, designed as an introduction to sport for young children. This longitudinal study identified trends in participation among children aged 4-12 years. Outcomes included continuation in the modified sports program, withdrawal from the program or transition to club sport competition. De-identified data on participant membership registrations in three popular sports in the Australian state of Victoria were obtained from each sport's state governing body over a 4-year period (2009-2012 for Sport A and 2010-2013 for Sports B and C). From the membership registrations, those who were enrolled in a modified sports program in the first year were tracked over the subsequent three years and classified as one of: transition (member transitioned from a modified sport program to a club competition); continue (member continued participation in a modified sport program; or withdraw (member discontinued a modified program and did not transition to club competition). Many modified sports participants were very young, especially males aged 4-6 years. More children withdrew from their modified sport program rather than transitioning. There were age differences between when boys and girls started, withdrew and transitioned from the modified sports programs. If we can retain children in sport it is likely to be beneficial for their health. This study highlights considerations for the development and implementation of sport policies and programming to ensure lifelong participation is encouraged for both males and females.

  20. Development of numerical processing in children with typical and dyscalculic arithmetic skills—a longitudinal study

    2013-01-01

    Numerical processing has been demonstrated to be closely associated with arithmetic skills, however, our knowledge on the development of the relevant cognitive mechanisms is limited. The present longitudinal study investigated the developmental trajectories of numerical processing in 42 children with age-adequate arithmetic development and 41 children with dyscalculia over a 2-year period from beginning of Grade 2, when children were 7; 6 years old, to beginning of Grade 4. A battery of numerical processing tasks (dot enumeration, non-symbolic and symbolic comparison of one- and two-digit numbers, physical comparison, number line estimation) was given five times during the study (beginning and middle of each school year). Efficiency of numerical processing was a very good indicator of development in numerical processing while within-task effects remained largely constant and showed low long-term stability before middle of Grade 3. Children with dyscalculia showed less efficient numerical processing reflected in specifically prolonged response times. Importantly, they showed consistently larger slopes for dot enumeration in the subitizing range, an untypically large compatibility effect when processing two-digit numbers, and they were consistently less accurate in placing numbers on a number line. Thus, we were able to identify parameters that can be used in future research to characterize numerical processing in typical and dyscalculic development. These parameters can also be helpful for identification of children who struggle in their numerical development. PMID:23898310

    This study aims to determine whether the communication and language skills of children who have a history of stuttering are different from children who do not have a history of stuttering at ages 2-5 years. This study utilizes data from the Early Language in Victoria Study (ELVS), a longitudinal study with a community sample of 1910 children recruited in Melbourne, Australia, as well as a concurrent study examining the onset and progression of stuttering. Participants with a history of stuttering (n = 181) and a control group without a history of stuttering (n = 1438) were identified according to the established protocol of these two existing studies. The stuttering group scored higher than the non-stuttering group on all of the communication and language outcomes measured. The group differences were statistically significant on four of the seven measures and these findings were maintained when potentially confounding factors were controlled for. Importantly, the children with a history of stuttering, as a group, and the control group without a history of stuttering demonstrated developmentally-appropriate early communication and language skills.

    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 (Mage = 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.

    Publications from the Avon Longitudinal Study of Parents and Children covering diet, growth, and obesity development during childhood are reviewed. Diet was assessed by food frequency questionnaires and food records. Growth data were collected by routine measurements, and in standardized clinics, body fatness was assessed by bioelectrical impedance and DXA (dual-energy X-ray absorptiometry) scans. Diets changed dramatically during the preschool period with an increase in the intake of free (added) sugars (12.3% rising to 16.4% of energy) that remained similar until adolescence. This was due to increased intake of energy-dense, nutrient-poor foods. Two periods of rapid growth were identified; infancy and mid-childhood (ages 7-11 y) and both were associated with obesity development. Diets with high energy density were associated with increasing fat mass from mid-childhood until adolescence. Genetic and dietary factors showed independent associations with increasing adiposity. At all ages studied, there were dietary inequalities related to maternal educational attainment that may influence inequalities found in obesity development. The Avon Longitudinal Study of Parents and Children has provided valuable insights into how disparities in diet and growth may affect the development of ill health in adulthood. © The Author(s) 2015.

    Although the literature has documented associations between sleep problems and internet addiction, the temporal direction of these relationships has not been established. The purpose of this study is to evaluate the bidirectional relationships between sleep problems and internet addiction among children and adolescents longitudinally. A four-wave longitudinal study was conducted with 1253 children and adolescents in grades 3, 5 and 8 from March 2013 to January 2014. The sleep problems of the student participants were measured by parental reports on the Sleep Habit Questionnaire, which catalogues early insomnia, middle insomnia, disturbed circadian rhythm, periodic leg movements, sleep terrors, sleepwalking, sleep talking, nightmares, bruxism, snoring and sleep apnoea. The severity of internet addiction was measured by students' self-reports on the Chen Internet Addiction Scale. Based on the results of time-lag models, dyssomnias (odds ratio = 1.31), especially early and middle insomnias (odds ratio = 1.74 and 2.24), sequentially predicted internet addiction, and internet addiction sequentially predicted disturbed circadian rhythm (odds ratio = 2.40), regardless of adjustment for gender and age. This is the first study to demonstrate the temporal relationship of early and middle insomnia predicting internet addiction, which subsequently predicts disturbed circadian rhythm. These findings imply that treatment strategies for sleep problems and internet addiction should vary according to the order of their occurrence.

    This two-year longitudinal study of the health-related quality of life (HRQoL) of children with face burns was conducted in three regional pediatric burn care centers. Subjects were 390 children less than 18 years old at injury, admitted for burn treatment from September 2001 to December 2004. HRQoL was assessed using the age-specific Burn Outcomes Questionnaire (BOQ) administered at scheduled time points following discharge up to 24 months thereafter. A psychosocial score was determined from domains of the BOQ, and these scores from children with both face burns and grafts were compared to those of children with non-face burns or with face burns but no face grafts. The parents of both the 0-4 year olds and the 5-18 year olds, who had facial burns and grafts, reported decreased BOQ psychosocial scores. When the teenagers (11-18 year olds) with facial burns and grafts filled out the BOQ themselves, they also reported low psychosocial scores compared to those with no facial burns with grafts. Severe face burn influences HRQoL in children. Additional psychosocial support is suggested to enhance recovery for patients with severe face burns and their families during the years following injury. Copyright © 2010 Elsevier Ltd and ISBI.

    1998-10-01

    The short- and long-term, and direct and indirect, relations between cognitively stimulating home environment and academic intrinsic motivation were investigated in a longitudinal study from childhood through early adolescence. Structural equations modeling was used to test the hypothesis that home environment positively predicts academic intrinsic motivation over this period. It was also hypothesized that home environmental processes would positively predict motivation controlling for socioeconomic status (SES). When children were age 8, home environment (comprising both direct observations and parent report) and SES were measured. Academic intrinsic motivation was assessed at ages 9, 10, and 13. Results supported the hypotheses. Home environment had statistically positive and significant, direct and indirect paths to academic intrinsic motivation from childhood through early adolescence, indicating both short- and long-term effects across these ages. Moreover, home environment was significant above and beyond SES. The findings revealed that children whose homes had a greater emphasis on learning opportunities and activities were more academically intrinsically motivated.

    There are few longitudinal studies of the prevalence of malocclusions and possible self-correction of malocclusions during the development of the dentition. Early intervention might be unnecessary if self-correction of the malocclusion occurs during the transition from the primary to the permanent dentition. Most studies are cross-sectional and in those of longitudinal design, the results are inconsistent and difficult to interpret. Malocclusions may or may not influence the quality of life in children and adolescents. Thus, evaluations of the influence of different malocclusions on quality of life will certainly underpin a broader understanding and knowledge about how malocclusions affect the daily life of young patients. This information may also be important when it comes to assessing the most appropriate time for starting orthodontic treatment, not only from a professional point of view, but also, most importantly, from the patients' perspective. The overall aim of this thesis was therefore to evaluate the prevalence of malocclusions, and to document changes occurring during the development of the dentition, from the primary dentition stage at age 3, through the mixed dentition at age 7, to the early permanent dentition at age 11.5 years. Further aims were to review the current state of knowledge about the impact of malocclusions on oral health related quality of life (OHRQoL) and to investigate how malocclusions affect the quality of life in a cohort of children, aged 11.5 years, whose dental care is provided by the Swedish Public Dental Service.

    More optimal parenting has been linked with lower rates of bullying. However, it is not clear whether parenting can alter the trajectories of bullying among children diagnosed with ADHD or ODD as well as those who are not so diagnosed. This study examined whether parenting at age 4-5 years was associated with changes in bullying over the next 4 years among children with Attention-deficit/Hyperactivity Disorder (ADHD) with and without comorbid Oppositional Defiant Disorder (ODD) relative to children without these disorders. Children from the New York metropolitan area (n = 162) were prospectively studied over six annual assessment points between preschool and 9 years of age. Parenting was assessed by laboratory observations of the parent and child; teachers rated child bullying, and parents reported on children's diagnostic status (Neither ADHD nor ODD, ADHD but not ODD, both ADHD and ODD). Children with comorbid ADHD and ODD were more likely to bully than the other two groups. Hierarchical linear modeling revealed a fall in bullying over five years. Diagnostic status was significantly associated with initial levels of bullying. Irrespective of diagnostic group, children receiving more parent support for child autonomy at age 4 to 5 years showed a significantly greater decline in bullying than those provided with little support for autonomy. There was no longitudinal link between parent negative affect, emotionally supportive parenting and quality of parent-child interactions with bullying. Greater parent support for child autonomy at age 4-5 years is related to reduced bullying. Interventions that encourage parent support for child autonomy at the time of entry into school may reduce bullying during early school years. © 2015 Association for Child and Adolescent Mental Health.

    Background Despite the increasing prevalence of overweight/obesity and its association to eating patterns in adolescents and adults, little is known about the relationship between problematic eating behaviours and body weight in the preschool years within the context of various social factors. This research aims to analyze the relationship between social factors, mothers' perceptions of their child's eating behaviour (picky eating and overeating), and body weight in preschool years, in a population-based cohort of preschoolers from Québec (Canada). Methods Analyses were performed on 1498 children from the Longitudinal Study of Child Development in Québec, a representative sample of children born in 1998 in the Canadian province of Québec. Eating behaviours (picky eating and overeating) were derived from questionnaires at 2.5, 3.5, and 4.5 years of age. BMI was calculated from children's measured height and weight at 4.5 years. Children's sex and birth weight, mothers' age, immigrant status, smoking status during pregnancy, and education level, family type, annual household income and income sufficiency, the number of overweight/obese parents, children's day-care attendance, and food insufficiency were part of the analysis. Multivariate logistic regressions were used to determine odds ratios for different body weight profiles (underweight, normal weight, at risk of overweight, overweight), and one-way analysis-of-variances (ANOVA) allowed for group comparisons of means. Results The proportion of children reported for each eating behaviour category remained quite stable across the years studied. Picky eating and overeating related to body weight among 4.5-year-old children, even when social and parental factors were accounted for in multivariate analysis. Picky eaters were twice as likely to be underweight at 4.5 years as children who were never picky eaters. Adjusted odds ratios revealed overeaters were 6 times more likely to be overweight at 4.5 years than were

    This paper provides a strategy for the assessment of brain function in longitudinal cohort studies of children. The proposed strategy invokes both domain-specific and omnibus intelligence test approaches. In order to minimise testing burden and practice effects, the cohort is divided into four groups with one-quarter tested at 6-monthly intervals in the 0–2-year age range (at ages 6 months, 1.0, 1.5 and 2.0 years) and at annual intervals from ages 3–20 (one-quarter of the children at age 3, another at age 4, etc). This strategy allows investigation of cognitive development and of the relationship between environmental influences and development at each age. It also allows introduction of new domains of function when age-appropriate. As far as possible, tests are used that will provide a rich source of both longitudinal and cross-sectional data. The testing strategy allows the introduction of novel tests and new domains as well as piloting of tests when the test burden is relatively light. In addition to the recommended tests for each age and domain, alternative tests are described. Assessment methodology and knowledge about child cognitive development will change over the next 20 years, and strategies are suggested for altering the proposed test schedule as appropriate.

    The relationship between language development in early childhood and the maturation of brain functions related to the human voice remains unclear. Because the development of the auditory system likely correlates with language development in young children, we investigated the relationship between the auditory evoked field (AEF) and language development using non-invasive child-customized magnetoencephalography (MEG) in a longitudinal design. Twenty typically developing children were recruited (aged 36-75 months old at the first measurement). These children were re-investigated 11-25 months after the first measurement. The AEF component P1m was examined to investigate the developmental changes in each participant's neural brain response to vocal stimuli. In addition, we examined the relationships between brain responses and language performance. P1m peak amplitude in response to vocal stimuli significantly increased in both hemispheres in the second measurement compared to the first measurement. However, no differences were observed in P1m latency. Notably, our results reveal that children with greater increases in P1m amplitude in the left hemisphere performed better on linguistic tests. Thus, our results indicate that P1m evoked by vocal stimuli is a neurophysiological marker for language development in young children. Additionally, MEG is a technique that can be used to investigate the maturation of the auditory cortex based on auditory evoked fields in young children. This study is the first to demonstrate a significant relationship between the development of the auditory processing system and the development of language abilities in young children.

    It is unknown whether childhood physical development in Asian populations differs from western populations, since no longitudinal analysis has been performed in Asian countries yet. Utilizing the 21st Century Longitudinal Survey in Newborns, we studied the timing of adiposity rebound (AR) among Japanese children and determined whether AR occurs earlier in obese children compared to nonobese children. Furthermore, we identified important demographic, social, and lifestyle factors that affect their physical development. We used data from the annual surveillance of Japanese children born in 2001, with 45,392 eligible subjects. We applied survival analysis to evaluate the AR and a trajectory method for the BMI transition across 5 ½ years. Time-dependent and time-independent factors affecting BMI changes were investigated using longitudinal analysis. Accounting for the known difference in prevalence between Japanese and Western children, we adopted a 95th percentile of BMI as criterion for obesity. Mean BMI at birth and at ages 1 ½, 2 ½, 3 ½, 4 ½, and 5 ½ years for all subjects were 12.6, 16.3, 16.1, 15.8, 15.5, and 15.4, respectively, showing a progressive reduction after 1 ½ years. However, among obese children at 5 ½ years, 39.6% had experienced AR as early as at age 4 ½ years. Controlling for sex, Cox's proportional hazards model showed that obese children had a 48.5% higher hazard to experience AR than nonobese children. The difference in BMI transition between obese and non-obese children was also captured by a trajectory method. In longitudinal analysis, BMI was lower for children who had a longer gestational period whereas children who received parental care from non-family members gained higher BMI values. With the 95th percentile cutoff for children obesity, obese Japanese children developed AR earlier than nonobese Japanese children, similar to those in Western countries reported in the literature.

    Background Molluscum contagiosum (MC) is a common skin condition in children. Consultation rates and current management in primary care, and how these have changed over time, are poorly described. An association between the presence of atopic eczema (AE) and MC has been shown, but the subsequent risk of developing MC in children with a diagnosis of AE is not known. Aim To describe the consultation rate and management of MC in general practice in the UK over time, and test the hypothesis that a history of AE increases the risk of developing MC in childhood. Design and setting Two studies are reported: a retrospective longitudinal study of MC cases and an age–sex matched case-cohort study of AE cases, both datasets being held in the UK Clinical Practice Research Datalink from 2004 to 2013. Method Data of all recorded MC and AE primary care consultations for children aged 0 to 14 years were collected and two main analyses were conducted using these data: a retrospective longitudinal analysis and an age–sex matched case-cohort analysis. Results The rate of MC consultations in primary care for children aged 0 to 14 years is 9.5 per 1000 (95% CI = 9.4 to 9.6). The greatest rate of consultations for both sexes is in children aged 1–4 years and 5–9 years (13.1 to 13.0 (males) and 13.0 to 13.9 (females) per 1000 respectively). Consultation rates for MC have declined by 50% from 2004 to 2013. Children were found to be more likely to have an MC consultation if they had previously consulted a GP with AE (OR 1.13; 95% CI = 1.11 to 1.16; P<0.005). Conclusion Consultations for MC in primary care are common, especially in 1–9-year-olds, but they declined significantly during the decade under study. A primary care diagnosis of AE is associated with an increased risk of a subsequent primary care diagnosis of MC. PMID:26639950

    Objectives This longitudinal population study aimed to investigate if maternal depression at different time points during the perinatal period impacts children's social-emotional development at 2 years of age. Methods Participants were women (n = 1235) who gave birth at Akershus University Hospital in Norway. Maternal depressive symptoms were assessed by using the Edinburgh Postnatal Depression Scale at pregnancy week 32 and at 8 weeks and 2 years postpartum, whereas children's social-emotional development at the age of 2 years was assessed by using the Ages and Stages Questionnaire: Social-Emotional. Bi- and multivariate logistic regression analyses were conducted to examine the linkage between maternal perinatal depression and children's early social-emotional development. Results Multivariate analyses showed that social-emotional problems in the child 2 years after birth were strongly associated with maternal depression at pregnancy week 32 (adjusted odds ratio (aOR) 3.4; 95 % CI 1.4-8.0), depression at 8 weeks postpartum (aOR 3.8; 95 % CI 1.7-8.6), and with depression at both time points (aOR 3.7; 95 % CI 1.5-10.1). Conclusion Findings indicate pre- and postnatal depression each bears an independent, adverse impact on children's social-emotional development.

    This Monograph presents the results of the Early Intervention Collaborative Study, a longitudinal investigation of the cognitive and adaptive behavior development of children with developmental disabilities and the adaptation of their parents, extending from infancy through middle childhood. The study was designed to generate and test conceptual models of child and family development and contribute to the knowledge base that informs social policy and practice. The sample for the investigation reported here consists of 183 children with Down syndrome, motor impairment, developmental delay and their families who were recruited at the time of their enrollment in an early intervention program in Massachusetts or New Hampshire. Data were collected at five time points between entry to early intervention and the child's 10th birthday. Home visits were conducted at each time point and included child assessments, maternal interview, and questionnaires completed independently by both parents. Trajectories in children's development and parental well-being were analyzed using hierarchical linear modeling. Predictor variables were measured at age 3 years when children were exiting early intervention programs. Children's type of disability predicted trajectories of development in cognition, social skills, and daily living skills. Children's type of disability also predicted changes in maternal (but not paternal) child-related and parent-related stress. Beyond type of disability, child self-regulatory processes (notably behavior problems and mastery motivation) and one aspect of the family climate (notably mother-child interaction) were key predictors of change in both child outcomes and parent well-being. A different aspect of the family climate--family relations--also predicted change in child social skills. Parent assets, measured as social support and problem-focused coping, predicted change in maternal and paternal parent-related stress respectively. The implications of

    Because of their history of widespread use in the United States and unknown long-term health effects, organophosphate pesticides (OPs) are being considered as a chemical class of interest in planning for the National Children's Study, a longitudinal study of children's environmental health. The availability and appropriate use of biomarkers to determine absorbed doses of environmental chemicals such as OPs are critical issues. Biomarkers of OP exposure are typically measured in blood and urine; however, postpartum meconium has been shown to be a promising matrix for assessing cumulative in utero exposure to the fetus, and studies are currently in progress to determine the utility of using saliva and amniotic fluid as matrices. In this article, we discuss the advantages and disadvantages of the currently available OP exposure monitoring methods (cholinesterase inhibition in blood, pesticides in blood, metabolites in urine and alternative matrices); study design issues for a large, long-term study of children's environmental health; and current research and future research needs. Because OPs are rapidly metabolized and excreted, the utility of one-time spot measurements of OP biomarkers is questionable unless background exposure levels are relatively stable over time or a specific time frame of interest for the study is identified and samples are collected accordingly. Biomarkers of OP exposure can be a valuable tool in epidemiology of children's environmental health, as long as they are applied and interpreted appropriately. PMID:14644670

    The Family Influences on Food Intake study (FIFI), is a longitudinal study on dietary habits of young children and the primary socialization of these habits during childhood and during the transition into adolescence. Special attention is paid to the development, validation and feasibility of instruments measuring as well dependent as independent variables useful for large scale surveys. Parents of preschool children from the first year (+/-3 years of age) of 56 school departments were asked to complete a self-administered questionnaire biennially. Data of 862 children was available for the first measurement (2008). A web based dietary record tool was developed to investigate the relative validity of the Food Frequency Questionnaire (FFQ) used in the study. Two hundred and seventeen parents completed the online tool for three non-consecutive days. The feasibility of the online data collection is investigated and the reported intake is compared with the FFQ estimates. Associations between nutritional knowledge and attitudes of the children's mothers and dietary patterns of the children (FFQ) are investigated as well as relations between parent and child characteristics and fruit and vegetable intake. Additionally, 70 teachers completed a questionnaire on their attitudes towards the school food policy. The teachers' responses are compared with responses of parents from a previous study. Finally, the feasibility of an animated web based fruit and vegetables preferences tool, to be used in the follow up surveys, has been investigated in 4-6 years old (n=139 for fruit and n=135 for vegetables). The findings are summarized in the present paper.

    Comprehension of spoken narratives requires coordination of multiple language skills. As such, for normal children narrative skills develop well into the school years and, during this period, are particularly vulnerable in the face of brain injury or developmental disorder. For these reasons, we sought to determine the developmental trajectory of narrative processing using longitudinal fMRI scanning. 30 healthy children between the ages of 5 and 18 enrolled at ages 5, 6, or 7, were examined annually for up to 10 years. At each fMRI session, children were presented with a set of five, 30s–long, stories containing 9, 10, or 11 sentences designed to be understood by a 5 year old child. FMRI data analysis was conducted based on a hierarchical linear model (HLM) that was modified to investigate developmental changes while accounting for missing data and controlling for factors such as age, linguistic performance and IQ. Performance testing conducted after each scan indicated well above the chance (p < 0.002) comprehension performance. There was a linear increase with increasing age in bilateral superior temporal cortical activation (BA 21 and 22) linked to narrative processing. Conversely, age-related decreases in cortical activation were observed in bilateral occipital regions, cingulate and cuneus, possibly reflecting changes in the default mode networks. The dynamic changes observed in this longitudinal fMRI study support the increasing role of bilateral BAs 21 and 22 in narrative comprehension, involving non-domain-specific integration in order to achieve final story interpretation. The presence of a continued linear development of this area throughout childhood and teenage years with no apparent plateau, indicates that full maturation of narrative processing skills has not yet occurred and that it may be delayed to early adulthood.

    Objective To describe the development of nevi from age of 3 to 8 in a birth cohort of children in Colorado, United States. Design Longitudinal observational study. Setting Large managed care organization, university, private primary care practices. Participants Annual convenience samples of children born in 1998, n= 137 to 870 (participation rates 19% to 76%). Recruitment through managed care organization, private primary care practices and community settings. Main Outcome Measures Total whole body nevus counts, nevus counts by size (< 2mm, 2 to <5 mm, ≥ 5mm), nevus counts for chronically and intermittently exposed body sites. Results Non-Hispanic white children had significantly more nevi than other racial/ethnic groups, and developed an average of 4-6 new nevi per year from age 3 to 8. Non-Hispanic white males had significantly more nevi than females beginning at age 6 (median 21 [inter-quartile range 12 – 30] vs. 17 [inter-quartile range 9 – 26], p=.002). This difference was due to nevi < 2mm and nevi in chronically exposed body sites. Development of new nevi leveled off in chronically exposed body sites at age 7, at a higher level for males than females. Conclusions Children in Colorado developed more small nevi and fewer larger nevi compared to children in other regions of the world, highlighting the importance of studying nevus development in various locations where sun exposure patterns and behavioral norms vary. The gender difference in nevus development could be due to variation in sun exposure and/or a biological predisposition of males to develop more nevi. Studies of nevus development can aid in the understanding of the complicated relationship between nevus development and malignant melanoma. PMID:19221259

    Childhood trauma exposure has been associated with deficits in cognitive functioning. The influence of timing of exposure on the magnitude and persistence of deficits is not well understood. The impact of exposure in early development has been especially under-investigated. This study examined the impact of interpersonal trauma exposure (IPT) in the first years of life on childhood cognitive functioning. Children (N=206) participating in a longitudinal birth cohort study were assessed prospectively for exposure to IPT (physical or emotional abuse or neglect, sexual abuse, witnessing maternal partner violence) between birth and 64 months. Child intelligent quotient (IQ) scores were assessed at 24, 64 and 96 months of age. Race/ethnicity, gender, socioeconomic status, maternal IQ, birth complications, birth weight and cognitive stimulation in the home were also assessed. IPT was significantly associated with decreased cognitive scores at all time points, even after controlling for socio-demographic factors, maternal IQ, birth complications, birth weight and cognitive stimulation in the home. IPT in the first 2 years appeared to be especially detrimental. On average, compared with children not exposed to IPT in the first 2 years, exposed children scored one-half SD lower across cognitive assessments. IPT in early life may have adverse effects on cognitive development. IPT during the first 2 years may have particular impact, with effects persisting at least into later childhood.

    The goal of the present article is to synthesize findings to date from the Delaware Longitudinal Study of Fraction Learning. The study followed a large cohort of children (N = 536) between Grades 3 and 6. The findings showed that many students, especially those with diagnosed learning disabilities, made minimal growth in fraction knowledge and that some showed only a basic grasp of the meaning of a fraction even after several years of instruction. Children with low growth in fraction knowledge during the intermediate grades were much more likely to fail to meet state standards on a broad mathematics measure at the end of Grade 6. Although a range of general and mathematics-specific competencies predicted fraction outcomes, the ability to estimate numerical magnitudes on a number line was a uniquely important marker of fraction success. Many children with mathematics difficulties have deep-seated problems related to whole number magnitude representations that are complicated by the introduction of fractions into the curriculum. Implications for helping students with mathematics difficulties are discussed. © Hammill Institute on Disabilities 2016.

    Attention problems form one of the core characteristics of Attention-Deficit Hyperactive Disorder (ADHD), a multifactorial neurodevelopmental disorder. From twin research it is clear that genes play a considerable role in the etiology and in the stability of ADHD in childhood. Association studies have focused on genes involved in the dopaminergic and serotoninergic systems, but with inconclusive results. This study investigated the effect of 26 Single Nucleotide Polymorphisms (SNPs) in genes encoding for serotonin receptors 2A (HTR2A), Catechol-O-Methyltransferase (COMT), Tryptophane Hydroxylase type 2 (TPH2), and Brain Derived Neurotrophic Factor (BDNF). Attention problems (AP) were assessed by parental report at ages 3, 7, 10, and 12 years in more than 16,000 twin pairs. There were 1148 genotyped children with AP data. We developed a longitudinal framework to test the genetic association effect. Based on all phenotypic data, a longitudinal model was formulated with one latent factor loading on all AP measures over time. The broad heritability for the AP latent factor was 82%, and the latent factor explained around 55% of the total phenotypic variance. The association of SNPs with AP was then modeled at the level of this factor. None of the SNPs showed a significant association with AP. The lowest p-value was found for the rs6265 SNP in the BDNF gene (p = 0.035). Overall, our results suggest no evidence for a role of these genes in childhood AP. PMID:21049304

    Receptive vocabulary develops rapidly in early childhood and builds the foundation for language acquisition and literacy. Variation in receptive vocabulary ability is associated with variation in children's school achievement, and low receptive vocabulary ability is a risk factor for under-achievement at school. In this study, bivariate and multivariate growth curve modelling was used to estimate trajectories of receptive vocabulary development in relation to a wide range of candidate child, maternal and family level influences on receptive vocabulary development from 4-8 years. The study sample comprised 4332 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Predictors were modeled as risk variables with the lowest level of risk as the reference category. In the multivariate model, risks for receptive vocabulary delay at 4 years, in order of magnitude, were: Maternal Non- English Speaking Background (NESB), low school readiness, child not read to at home, four or more siblings, low family income, low birthweight, low maternal education, maternal mental health distress, low maternal parenting consistency, and high child temperament reactivity. None of these risks were associated with a lower rate of growth from 4-8 years. Instead, maternal NESB, low school readiness and maternal mental health distress were associated with a higher rate of growth, although not sufficient to close the receptive vocabulary gap for children with and without these risks at 8 years. Socio-economic area disadvantage, was not a risk for low receptive vocabulary ability at 4 years but was the only risk associated with a lower rate of growth in receptive vocabulary ability. At 8 years, the gap between children with and without socio-economic area disadvantage was equivalent to eight months of receptive vocabulary growth. These results are consistent with other studies that have shown that social gradients in children's developmental outcomes

    This study aimed to test a 5-wave sequential mediation model linking maternal mind-mindedness during infancy to children's school readiness in kindergarten through a serial mediation involving child language and effortful control in toddlerhood and the preschool years. Among a sample of 204 mother-child dyads, we assessed maternal mind-mindedness when children were aged 1 year, child expressive vocabulary at age 2, effortful control at ages 3 and 4, and finally cognitive school readiness in kindergarten. The results corroborated the model, suggesting that the prospective association between early mind-mindedness and later cognitive school readiness was entirely mediated by the proposed sequence of mediators, all of which were necessary to account for this longitudinal association. These findings suggest that the potential of parental mind-mindedness to support children's cognitive development may have been underestimated, and that its putative positive influence may take the form of a developmental cascade unfolding during the preschool years and entailing the acquisition of basic skills that serve as building blocks for further learning and development.

    Concerns have developed for the possible negative health effects of radiofrequency electromagnetic field (RF-EMF) exposure to children's brains. The purpose of this longitudinal study was to investigate the association between mobile phone use and symptoms of Attention Deficit Hyperactivity Disorder (ADHD) considering the modifying effect of lead exposure. A total of 2,422 children at 27 elementary schools in 10 Korean cities were examined and followed up 2 years later. Parents or guardians were administered a questionnaire including the Korean version of the ADHD rating scale and questions about mobile phone use, as well as socio-demographic factors. The ADHD symptom risk for mobile phone use was estimated at two time points using logistic regression and combined over 2 years using the generalized estimating equation model with repeatedly measured variables of mobile phone use, blood lead, and ADHD symptoms, adjusted for covariates. The ADHD symptom risk associated with mobile phone use for voice calls but the association was limited to children exposed to relatively high lead. The results suggest that simultaneous exposure to lead and RF from mobile phone use was associated with increased ADHD symptom risk, although possible reverse causality could not be ruled out.

    There is ample evidence that individuals with dyslexia have a phonological deficit. A growing body of research also suggests that individuals with dyslexia have problems with categorical perception, as evidenced by weaker discrimination of between-category differences and better discrimination of within-category differences compared to average readers. Whether the categorical perception problems of individuals with dyslexia are a result of their reading problems or a cause has yet to be determined. Whether the observed perception deficit relates to a more general auditory deficit or is specific to speech also has yet to be determined. To shed more light on these issues, the categorical perception abilities of children at risk for dyslexia and chronological age controls were investigated before and after the onset of formal reading instruction in a longitudinal study. Both identification and discrimination data were collected using identical paradigms for speech and non-speech stimuli. Results showed the children at risk for dyslexia to shift from an allophonic mode of perception in kindergarten to a phonemic mode of perception in first grade, while the control group showed a phonemic mode already in kindergarten. The children at risk for dyslexia thus showed an allophonic perception deficit in kindergarten, which was later suppressed by phonemic perception as a result of formal reading instruction in first grade; allophonic perception in kindergarten can thus be treated as a clinical marker for the possibility of later reading problems.

    This longitudinal study modeled lexical development among children who spoke Vietnamese as a first language (L1) and English as a second language (L2). Participants (n=33, initial mean age of 7.3 years) completed a total of eight tasks (four in each language) that measured vocabulary knowledge and lexical processing at four yearly time points. Multivariate hierarchical linear modeling was used to calculate L1 and L2 trajectories within the same model for each task. Main findings included (a) positive growth in each language, (b) greater gains in English resulting in shifts toward L2 dominance, and (c) different patterns for receptive and expressive domains. Timing of shifts to L2 dominance underscored L1 skills that are resilient and vulnerable to increases in L2 proficiency. PMID:23869741

    Children with pragmatic language impairment (PLI) show impairments in the use of language in social contexts. Although the issue has been gaining attention in recent literature, not much is known about the developmental trajectories of children who experience pragmatic language problems. Since narrative competence is an important predictor of both academic and social success, evaluating narrative competence in children with PLI is deemed important. To examine the development of narrative competence of children with PLI compared with typically developing (TD) children using a prognostic longitudinal design. Using the Dutch adaptation of the Renfrew Bus Story Test, narrative competence was assessed at ages 5-7 for a group of 84 children with PLI and a group of 81 TD children. Groups were compared on measures of narrative productivity, organization of story content and cohesion. Results showed an increase in narrative competence for both groups across most time points. The PLI group obtained lower scores on measures of narrative productivity and story content organization compared with their TD peers at all time points, but did not show more problems related to narrative cohesion. Most problems in the domain of narrative productivity and story content organization were shown to be independent of lower non-verbal intelligence. The developmental trajectory for the PLI group was largely similar to that of their TD peers, and showed a persistent developmental delay of approximately one year. Furthermore, qualitative differences were visible in the proportion of irrelevant T-units, which was consistently higher in the PLI group. The different narrative measures were found to be relatively stable over time. The results of this study suggest that narrative difficulties of children identified as pragmatically impaired persist at least until middle childhood. The persistence of the measured developmental delay, combined with the finding of qualitative differences, support the

    We examined the relationship between parent-perceived neighborhood safety and children's physical activity, sedentary behavior, body mass, and obesity status using 9 years of longitudinal data (1999-2007) on a cohort of approximately 19,000 US kindergartners from the Early Childhood Longitudinal Study. Children's height and weight measurements and parent perceptions of neighborhood safety were available in kindergarten and in the first, third, fifth, and eighth grades. Dependent variables included age- and gender-specific body mass index percentile, obesity status, and parent- or child-reported weekly physical activity and television-watching. Pooled cross-sectional and within-child longitudinal regression models that controlled for child, family, and school characteristics were fitted. Both cross-sectional and longitudinal models indicated that children whose parents perceived their neighborhoods as unsafe watched more television and participated in less physical activity, although the magnitude of this association was much weaker in longitudinal models. However, there was no significant association between parent-perceived neighborhood safety and children's body mass index.

    Very preterm (VP; gestational age <32 weeks) and very low birth weight (VLBW; <1500 grams) is related to attention problems in childhood and adulthood. The stability of these problems into adulthood is not known. The Bavarian Longitudinal Study is a prospective cohort study that followed 260 VP/VLBW and 229 term-born individuals from birth to adulthood. Data on attention were collected at 6, 8, and 26 years of age, using parent reports, expert behavior observations, and clinical ADHD diagnoses. At each assessment, VP/VLBW individuals had significantly more attention problems, shorter attention span, and were more frequently diagnosed with ADHD than term-born comparisons. In both VP/VLBW and term-born individuals, overall, attention span increased and attention problems decreased from childhood to adulthood. Attention problems and attention span were more stable over time for VP/VLBW than term-born individuals. Similarly, ADHD diagnoses showed moderate stability from childhood to adulthood in VP/VLBW, but not in term-born individuals. However, when those with severe disabilities were excluded, differences between VP/VLBW and term-born individuals reduced. Despite improvement in attention regulation from childhood to adulthood, children born very preterm remained at increased risk for attention problems in adulthood. In contrast, term-born children with clinical attention problems outgrew these by adulthood. As inattentive behavior of VP/VLBW children may be overlooked by teachers, it may be necessary to raise awareness for school intervention programs that reduce attention problems in VP/VLBW children. © 2015 Association for Child and Adolescent Mental Health.

    The aim of this longitudinal study was to compare the prevalence of malocclusion at ages 3 and 7 years in a sample of children, exploring the hypothesis that prevalence of malocclusion is higher at 3 than at 7 years of age and may be influenced by sucking habits. The study sample comprised 386 children (199 girls and 187 boys), aged 3 years at study start, sourced from three Public Dental Service clinics in Sweden. Malocclusion was diagnosed by clinical examination, using a specific protocol. Data on allergy, traumatic injuries, sucking habits, and breathing pattern including nocturnal breathing disturbances were obtained by means of a questionnaire answered by child and parent in conjunction with the initial and final clinical examination. The overall prevalence of malocclusion decreased significantly, from 70 to 58% (P < 0.0001): predominantly anterior open bite, excessive overjet, and Class III malocclusion. Although high rates of spontaneous correction were also noted for deep bite, Class II malocclusion and posterior and anterior crossbites, new cases developed at almost the same rate; thus, the prevalence was unchanged at the end of the observation period. Anterior open bite and posterior crossbite were the only conditions showing significant associations with sucking habits. The results confirm the hypothesis of higher prevalence of malocclusion at 3 years of age and clearly support the strategy of deferring orthodontic correction of malocclusion until the mixed dentition stage.

    To report the prevalence of hearing problems and the hearing sequelae in school-aged children with trisomy 21 in a longitudinal study. All children with trisomy 21 were identified via schools, community-based child development centres, general practitioners, or the universal newborn hearing screen. Audiological data and otorhinolaryngological problems were prospectively entered in to the Audiological Surveillance Programme database from each visit. Retrospective review of the Audiological Surveillance Programme database in the Glasgow area (United Kingdom) of all children reviewed between 2004 and 2012. All pre-teenaged children with trisomy 21 of school age (aged 5-12 years old). Hearing thresholds, aetiology of hearing loss and management of hearing loss was determined for the cohort of children. A total of 102 children were included. Fifty-four had normal hearing. Twenty-six had fluctuating otitis media with effusion; five had hearing in normal limits, six were managed with hearing aids, fourteen were managed conservatively, and one had ventilation tube insertion. Fifteen had persistent otitis media with effusion; four had ventilation tube insertion; and nine were managed with hearing aids. Seven had mixed hearing loss with four required hearing aids. Otitis media with effusion was the commonest cause of hearing impairment; effusions may fluctuate through the pre-teenaged years, and thus, hearing aids are beneficial. Ventilation tube insertion and bone-conducting hearing aids were useful when ear-level hearing aids were not tolerated. Mixed hearing loss occurred in later years as sensorineural hearing loss developed on a background of otitis media with effusion. © 2015 John Wiley & Sons Ltd.

    Data on mental health care use of children and adolescents in Germany is scarce. This study investigates the degree of mental health care use, its trajectories and influencing factors among children and adolescents in Germany, using longitudinal data of the BELLA study. The BELLA study is the mental health module of the representative German National Health Interview and Examination Survey for children and adolescents (KiGGS). Baseline data of N = 2,863 participants aged 7-17 years were collected between 2003 and 2006. The study sample was followed up in three additional measurement points, assessing general mental health problems and impairment, specific mental health problems, and mental health care use. In the current study, we analysed data from the first three measurement points. At baseline, 5.9 % of all participants used mental health care in the past 12 months. Among those with general mental health problems, 29.5 % sought professional help. Only a minority of participants reporting mental health care use at baseline also sought help at the following two measurement points. Analysing a random intercept only model, mental health care use was found to be more likely among participants living in larger communities as well as in the Eastern part of Germany, among those participants with impairment of mental health problems, and signs of externalizing problems. Our results indicate a temporary character of mental health care use. Participants' impairment was identified to be the strongest predictor of mental health care use.

    The use of tobacco products is the major cause of chronic diseases morbidity and mortality. Most smokers start the smoking habits from childhood and adolescent stages. This was a cross-sectional study. A total of 1654 subjects (854 boys and 800 girls), aged 11 to 18 years, who were part of the Ellisras Longitudinal Study completed the questionnaire. Association between tobacco products use and habits, attitudes and beliefs were explored in this study. Logistic regression was used to estimate the association. The prevalence of tobacco product use increases with increasing (4.9 to 17.1%) age among boys whereas girls do not smoke cigarette but only considerable number (1.0 to 4.1%) use home made tobacco products (pipe and snuff) among the Ellisras rural children. Parents and grand parents play a significant (about 50%) role in influencing smoking behaviour among the Ellisras rural children. Seeing actors smoking on TV shows was positively associated (p < 0.05) with smoking (OR = 2.3 95%CI (1.3-4.1 and OR = 2.3 95%CI 1.3-4.1 after adjusting for age and gender). However, women who smoke cigarette were significantly (p < 0.001) associated with success and success and wealth (OR = 2.8, 95% CI 1.5-5.2) even after adjusting for age and gender (OR = 2.9 95% CI 1.5-5.4). The usage of tobacco products was high among older boys. Girls did not smoke cigarette. This tobacco use behaviour mirrors the cultural norms and adult behaviour. The association of this tobacco used products with biological parameters will shed more light on the health of these children over time.

    The symptom profile and neuropsychological functioning of individuals with Attention Deficit/Hyperactivity Disorder (ADHD), change as they enter adolescence. It is unclear whether variation in brain structure and function parallels these changes, and also whether deviations from typical brain development trajectories are associated with differential outcomes. This paper describes the Neuroimaging of the Children's Attention Project (NICAP), a comprehensive longitudinal multimodal neuroimaging study. Primary aims are to determine how brain structure and function change with age in ADHD, and whether different trajectories of brain development are associated with variations in outcomes including diagnostic persistence, and academic, cognitive, social and mental health outcomes. NICAP is a multimodal neuroimaging study in a community-based cohort of children with and without ADHD. Approximately 100 children with ADHD and 100 typically developing controls will be scanned at a mean age of 10 years (range; 9-11years) and will be re-scanned at two 18-month intervals (ages 11.5 and 13 years respectively). Assessments include a structured diagnostic interview, parent and teacher questionnaires, direct child cognitive/executive functioning assessment and magnetic resonance imaging (MRI). MRI acquisition techniques, collected at a single site, have been selected to provide optimized information concerning structural and functional brain development. This study will allow us to address the primary aims by describing the neurobiological development of ADHD and elucidating brain features associated with differential clinical/behavioral outcomes. NICAP data will also be explored to assess the impact of sex, ADHD presentation, ADHD severity, comorbidities and medication use on brain development trajectories. Establishing which brain regions are associated with differential clinical outcomes, may allow us to improve predictions about the course of ADHD.

    Background Concerns have developed for the possible negative health effects of radiofrequency electromagnetic field (RF-EMF) exposure to children’s brains. The purpose of this longitudinal study was to investigate the association between mobile phone use and symptoms of Attention Deficit Hyperactivity Disorder (ADHD) considering the modifying effect of lead exposure. Methods A total of 2,422 children at 27 elementary schools in 10 Korean cities were examined and followed up 2 years later. Parents or guardians were administered a questionnaire including the Korean version of the ADHD rating scale and questions about mobile phone use, as well as socio-demographic factors. The ADHD symptom risk for mobile phone use was estimated at two time points using logistic regression and combined over 2 years using the generalized estimating equation model with repeatedly measured variables of mobile phone use, blood lead, and ADHD symptoms, adjusted for covariates. Results The ADHD symptom risk associated with mobile phone use for voice calls but the association was limited to children exposed to relatively high lead. Conclusions The results suggest that simultaneous exposure to lead and RF from mobile phone use was associated with increased ADHD symptom risk, although possible reverse causality could not be ruled out.

    The main aim of this study was to investigate the occurrence of cancer-related posttraumatic stress disorder (PTSD) among parents of children on cancer treatment. A longitudinal design with assessments at one week (T1), two (T2), and four (T3) months after the child's diagnosis was used. Two hundred and fourteen parents (107 mothers, 107 fathers) participated at T1-T3. The PTSD Checklist Civilian (PCL-C), a self-report screening instrument for PTSD, was answered by parents over the telephone. According to the PCL-C symptom criteria method 33%, more mothers than fathers, score as potential cases of acute stress disorder (ASD) at T1, whereas 28% as potential cases of PTSD at T2 and 22% at T3. The levels of acute- and posttraumatic stress symptoms show a linear, descending pattern, and mothers report higher levels than fathers. Half of the parents who score as potential cases of ASD a week after the child's diagnosis score as potential cases of PTSD four months later. The findings illustrate that a group of parents of children with cancer experience serious psychological distress related to their child's disease. A traumatic stress perspective on childhood cancer should be applied to paediatric oncology care and appropriate psychosocial interventions should be offered to parents when needed.

    Objective Evaluate effects of local weather conditions on physical activity in early childhood. Methods Longitudinal prospective cohort study of 372 children, 3 years old at enrollment, drawn from a major US metropolitan community. Accelerometer-measured (RT3) physical activity was collected every 4 months over 5 years and matched with daily weather measures: day length, heating/cooling degrees (degrees mean temperature < 65°F or ≥ 65°F, respectively), wind, and precipitation. Mixed regression analyses, adjusted for repeated measures, were used to test the relationship between weather and physical activity. Results Precipitation and wind speed were negatively associated with total physical activity and moderate-vigorous physical activity (P<0.0001). Heating and cooling degrees were negatively associated with total physical activity and moderate-vigorous physical activity and positively associated with inactivity (all P<0.0001), independent of age, sex, race, BMI, day length, wind, and precipitation. For every 10 additional heating degrees there was a five-minute daily reduction in moderate-vigorous physical activity. For every additional 10 cooling degrees there was a 17-minute reduction in moderate-vigorous physical activity. Conclusions Inclement weather (higher/lower temperature, greater wind speed, more rain/snow) is associated with less physical activity in young children. These deleterious effects should be considered when planning physical activity research, interventions, and policies. PMID:25423667

  6. Local social environmental factors are associated with household food insecurity in a longitudinal study of children

    2012-01-01

    Background Food insecurity is a significant public health problem in North America and elsewhere. The prevalence of food insecurity varies by country of residence; within countries, it is strongly associated with household socioeconomic status, but the local environment may also play an important role. In this study, we analyzed secondary data from a population-based survey conducted in Québec, Canada, to determine if five local environmental factors: material and social deprivation, social cohesion, disorder, and living location were associated with changes in household food insecurity over a period of 6 years, while adjusting for household socioeconomic status (SES) and other factors. Methods Data from the Québec Longitudinal Study of Child Development, following same-aged children from 4–10 y of age, were analyzed using generalized estimating equations, to determine the longitudinal association between these environmental factors and food insecurity over a period of 6 years. Results Of the 2120 children originally included in the cohort, 1746 (82%) were included in the present analysis. The prevalence of food insecurity was 9.2% when children were 4 y of age (95% CI: 7.8 – 10.6%) but no significant changes were observed over time. On average over the 6 year period, three environmental factors were positively related to food insecurity: high social deprivation (OR 1.62, 95%CI: 1.16 – 2.26), low social cohesion (OR 1.45 95%CI: 1.10 – 1.92), and high disorder (OR 1.76, 95%CI: 1.37 – 2.27), while living location and material deprivation were not related to food insecurity. These associations were independent of household SES and other social variables. Conclusion These results highlight the potential role of the local social environment in preventing and ameliorating food insecurity at the household level. Stakeholders providing food security interventions at the community level should consider interactions with local social characteristics and perhaps

    This study examined the concurrent and cross-time relations of parental observed warmth and positive expressivity to children's situational facial and self-reported empathic responding, social competence, and externalizing problems in a sample of 180 elementary school children. Data was collected when the children were in second to fifth grades (age: M = 112.8 months), and again 2 years later. Cross-sectional and longitudinal structural equation models supported the hypothesis that parents' (mostly mothers') positive expressivity mediated the relation between parental warmth and children's empathy, and children's empathy mediated the relation between parental positive expressivity and children's social functioning. These relations persisted after controlling for prior levels of parenting and child characteristics. Moreover, concurrent and cross-time consistencies were found on measures of parenting, children's situational empathic responding, and social functioning.

    Helicobacter pylori infection has been associated with early childhood growth impairment in high- and middle-income countries; however, few studies have examined this relationship within low-income countries or have used a longitudinal design. The possible effects of H. pylori infection on growth trajectories were examined in a cohort of young Ethiopian children. In 2011/12, 856 children (85.1% of the 1006 original singletons in a population-based birth cohort) were followed up at age 6.5 years. An interviewer-led questionnaire administered to mothers provided information on demographic and lifestyle variables. Height and weight were measured twice, and the average of the two measurements was used. Exposure to H. pylori infection was assessed using a rapid H. pylori stool antigen test. The independent associations of positive H. pylori infection status (measured at ages 3 and 6.5 years) with baseline height and weight (age 3 years) and height and weight growth trajectory (from age 3 to 6.5 years) were modelled using hierarchical linear models. At baseline (age 3 years), the children's mean height was 85.7cm and their mean weight was 11.9kg. They gained height at a mean rate of 8.7cm/year, and weight at a mean rate of 1.76kg/year. H. pylori infection was associated with lower baseline measurements and linear height trajectory (β=-0.74cm and -0.79cm/year, respectively), after controlling for demographics and markers of socio-economic status. However, the positive coefficient was associated with quadratic growth in height among H. pylori-infected children (β=0.28, 95% confidence interval 0.07 to 0.49, p<0.01), and indicated an increase in height trajectory as the child increased in age. A non-significant difference in baseline and trajectory of weight was observed between H. pylori-infected and non-infected children. These findings add to the growing body of evidence supporting that H. pylori infection is inversely associated with childhood growth trajectory, after

    The purpose of the present study was to describe longitudinal changes in accumulation of dental plaque and gingival inflammation, and their effect on changes in sulcus depth of children and young adolescents. Forty one boys and 37 girls aged 1-12 years living in a rural community in Israel were included in the study. At baseline and 12 months later, Loe's Plaque Index (PlI) and Gingival Index (GI), and sulcus depth were examined. Boys' mean age was significantly lower than girls' mean age (6.04 + 2.76 years, and 7.68 + 2.84 years respectively). PlI, GI and sulcus depth were higher in the 12-month examination compared to baseline. PlI was slightly higher in boys, while GI was slightly higher in girls. These differences however, were not statistically significant. At baseline, sulcus depth was significantly greater in girls than in boys, while at 12 months the difference was not significant. The children were grouped by age as follows: 1-5 years, 6-9 years and 10-12 years. PlI and GI mean scores were significantly higher among the 6-9-year-old individuals. Mean sulcus depth for the 10-12-year-old children was greater than that of the 6-9-year-olds at baseline and after 12 months. The effect of age, PlI and GI on the outcome variable (sulcus depth) was examined using a correlation matrix. At baseline, age showed the highest correlation (r = 0.659) followed by GI (r = 0.364) and PlI (r = 0.123). The same pattern was also observed at the 12 months examination.(ABSTRACT TRUNCATED AT 250 WORDS)

    Although numerous people grow up speaking more than one language, the impact of bilingualism on brain developing neuroanatomy is still poorly understood. This study aimed to determine whether the changes in the mean fractional-anisotropy (MFA) of language pathways are different between bilingual and monolingual children. Simultaneous-bilinguals, sequential-bilinguals and monolingual, male and female 10-13 years old children participated in this longitudinal study over a period of two years. We used diffusion tensor tractography to obtain mean fractional-anisotropy values of four language related pathways and one control bundle: 1-left-inferior-occipitofrontal fasciculus/lIFOF, 2-left-arcuate fasciculus/lAF/lSLF, 3-bundle arising from the anterior part of corpus-callosum and projecting to orbital lobe/AC-OL, 4-fibres emerging from anterior-midbody of corpus-callosum (CC) to motor cortices/AMB-PMC, 5- right-inferior-occipitofrontal fasciculus rIFOF as the control pathway unrelated to language. These values and their rate of change were compared between 3 groups. FA-values did not change significantly over two years for lAF/lSLF and AC-OL. Sequential-bilinguals had the highest degree of change in the MFA value of lIFOF, and AMB-PMC did not present significant group differences. The comparison of MFA of lIFOF yielded a significantly higher FA-value in simultaneous bilinguals compared to monolinguals. These findings acknowledge the existing difference of the development of the semantic processing specific pathway between children with different semantic processing procedure. These also support the hypothesis that age of second language acquisition affects the maturation and myelination of some language specific white-matter pathways.

    The aim of the study was to reveal longitudinal changes in electroencephalogram spectral power and frequency (percentage frequency composition of EEG and alpha peak frequency) patterns in normal children from northern Russia. Fifteen children (9 girls and 6 boys) participated in the study. The resting state (eyes closed) EEGs were recorded yearly (2005-2013) from age 8 to age 16-17 for each child. EEG frequency patterns were estimated as the percentages of waves with a 1 Hz step revealed by measuring the interval durations between points crossing zero (isoline) by a curve. EEG spectral power changes were analyzed for delta (1.5-4 Hz), theta (4-7.5 Hz), alpha-1 (7.5-9.5 Hz), alpha-2 (9.5-12.5 Hz), beta-1 (12.5-18 Hz) and beta-2 (18-30 Hz) bands. According to the frequency composition of the EEG signals fast synchronous, polymorphous synchronous, polymorphous desynchronous and slow synchronous types of children EEG were revealed. These EEG types were relatively stable during adolescence. In these EEG types, the frequency patterns and spectral power dynamics with age had several common and specific features. Slow wave percentage and spectral power in the delta band remarkably decreased with age in all groups. Starting from the theta band the EEG types were characterized by different EEG spectral power changes with age. In fast synchronous EEG type, the theta and alpha-1 EEG power decreased, and the alpha-2 power increased in the occipital and parietal areas. The polymorphous synchronous type was characterized by increased both the alpha-1 and alpha-2 power with regional peculiarities. In the polymorphous desynchronous type spectral power in all bands decreased with age, and in the slow synchronous type, the alpha-1 power massively increased with age. Obtained results suggest predictive strength of the spatial-frequency patterns in EEG for its following maturation through the years.

    To assess the effects of long-term variations in ambient air pollutants on longitudinal changes in exhaled nitric oxide (FeNO), a potentially useful biomarker of eosinophilic airway inflammation, based on data from the southern California Children's Health Study. Based on a cohort of 1211 schoolchildren from eight Southern California communities with FeNO measurements in 2006-2007 and 2007-2008, regression models adjusted for short-term effects of air pollution were fitted to assess the association between changes in annual long-term exposures and changes in FeNO. Increases in annual average concentrations of 24-h average NO2 and PM2.5 (scaled to the IQR of 1.8 ppb and 2.4 μg/m(3), respectively) were associated with a 2.29 ppb (CI 0.36 to 4.21; p=0.02) and a 4.94 ppb (CI 1.44 to 8.47; p=0.005) increase in FeNO, respectively, after adjustments for short-term effects of the respective pollutants. In contrast, changes in annual averages of PM10 and O3 were not significantly associated with changes in FeNO. These findings did not differ significantly by asthma status. Changes in annual average exposure to current levels of ambient air pollutants are significantly associated with changes in FeNO levels in children, independent of short-term exposures and asthma status. Use of this biomarker in population-based epidemiological research has great potential for assessing the impact of changing real world mixtures of ambient air pollutants on children's respiratory health.

  14. Skin pigmentation, sun exposure and vitamin D levels in children of the Avon Longitudinal Study of Parents and Children

    PubMed Central

    2014-01-01

    Background 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. Methods 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). Results 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. Conclusions 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. PMID:24924479

    Obesity and its co-occurrence with household food insecurity among low-income families is a public health concern, particularly because both are associated with later adverse health consequences. Our aim was to examine the relationship between household food insecurity with and without hunger in infancy and later childhood with weight status at 2 to 5 years. This longitudinal study uses household food-security status, weight, and height data collected at the first infancy and last child (2 to 5 years) Special Supplemental Nutrition Program for Women, Infants, and Children visits. Household food security was based on parent/caretaker responses to a four-question subscale of the 18-item Core Food Security Module. Obesity was defined as sex-specific body mass index for age ≥ 95th percentile. A diverse (58.6% non-white) low-income sample of 28,353 children participating in the Massachusetts Special Supplemental Nutrition Program for Women, Infants, and Children (2001-2006); 24.9% of infants and 23.1% of children lived in food-insecure households and 17.1% were obese at their last child visit. Multivariate logistic regression analyses assessed the association between household food-security status during the infant and child visits, and risk of preschool obesity, while controlling for child race/Hispanic ethnicity, sex, child and household size, maternal age, education, and prepregnancy weight. Interactions between these covariates and household food-security status were also examined. In cases of multiple comparisons, a Bonferroni correction was applied. Persistent household food insecurity without hunger was associated with 22% greater odds of child obesity (odds ratio=1.22; 95% CI 1.06 to 1.41) compared with those persistently food secure (P<0.05). Maternal prepregnancy weight status modified this association with children of underweight (adjusted odds ratio=3.22; 95% CI 1.70 to 6.11; P=0.003) or overweight/obese (adjusted odds ratio=1.34; 95% CI 1.11 to 1.62; P=0

    Objective This study aimed to examine friendship networks and social support outcomes for mothers according to patterns of playgroup participation. Methods Data from the Longitudinal Study of Australian Children were used to examine the extent to which patterns of playgroup participation across the ages of 3–19 months (Wave 1) and 2–3 years (Wave 2) were associated with social support outcomes for mothers at Wave 3 (4–5 years) and four years later at Wave 5 (8–9 years). Analyses were adjusted for initial friendship attachments at Wave 1 and other socio-demographic characteristics. Results Log-binomial regression models estimating relative risks showed that mothers who never participated in a playgroup, or who participated at either Wave 1 or Wave 2 only, were 1.7 and 1.8 times as likely to report having no support from friends when the child was 4–5 years, and 2.0 times as likely to have no support at age 8–9 years, compared with mothers who persistently participated in playgroup at both Wave 1 and Wave 2. Conclusion These results provide evidence that persistent playgroup participation may acts as a protective factor against poor social support outcomes. Socially isolated parents may find playgroups a useful resource to build their social support networks. PMID:26181426

    Cross-sectional studies have reported inconsistent findings for the association between recreational swimming pool attendance and asthma and allergic diseases in childhood. To examine whether swimming in infancy and childhood was associated with asthma and allergic symptoms at age 7 and 10 years in a UK longitudinal population-based birth cohort, the Avon Longitudinal Study of Parents and Children. Data on swimming were collected by questionnaire at 6, 18, 38, 42, 57, 65, and 81 months. Data on rhinitis, wheezing, asthma, eczema, hay fever, asthma medication, and potential confounders were collected through questionnaires at 7 and 10 years. Spirometry and skin prick testing were performed at 7 to 8 years. Data for analysis were available for 5,738 children. At age 7 years, more than 50% of the children swam once per week or more. Swimming frequency did not increase the risk of any evaluated symptom, either overall or in atopic children. Children with a high versus low cumulative swimming pool attendance from birth to 7 years had an odds ratio of 0.88 (95% confidence interval, 0.56-1.38) and 0.50 (0.28-0.87), respectively, for ever and current asthma at 7 years, and a 0.20 (0.02-0.39) standard deviation increase in the forced midexpiratory flow. Children with asthma with a high versus low cumulative swimming had an odds ratio for current asthma at 10 years of 0.34 (0.14-0.80). This first prospective longitudinal study suggests that swimming did not increase the risk of asthma or allergic symptoms in British children. Swimming was associated with increased lung function and lower risk of asthma symptoms, especially among children with preexisting respiratory conditions.

    Objective: Nasopharynx is an important compartment of the upper airway. It is closely associated with the characteristic craniofacial skeletal pattern related to sleep breathing. The present study aimed to investigate the growth pattern of the nasopharynx during rapid puberty growth period. Methods: Thirty non-snoring children (aged 8 to 11 years old) were selected by means of questionnaires and clinical examination. Periodic yearly follow up using MRI, lateral cephalogram, and polysomnograph (PSG) was done in these children. Fifty-one final mixed longitudinal samples were consisted of 23 children completed three consecutive follow-up, and 5 children completed two consecutive follow-up. The yearly changes of the nasopharynx and craniofacial structures were measured. ANOVA was used to evaluate the yearly growth of the nasopharynx. Correlated analysis was used to explore the potential influencing factors of craniofacial structures. Results: The rapid growth period of the nasopharynx located in the age range of 8-10 years old, during which the transverse dimension of the nasopharynx developed rapidly, while the rapid development of the sagittal dimension of the nasopharynx was around 12-13 years old. The growth of the nasopharynx was continuous. The changes in the cross-sectional area of the nasopharynx (⊿CSA) was positively correlated with the changes in distance between mandible of glossopharyngeus (⊿M), distance of hyoid to cervical anterior surface (⊿H-CVP), and anterior pharyngeal distance of glossopharyngeus (⊿AD) (r=0.363, 0.363, 0.323, respectively, all P<0.05). The changes in the volume of the nasopharynx (⊿V) was positively correlated with the changes in upper facial height (⊿N-ANS), ⊿M, and ⊿AD (r=0.336, 0.413, 0.478, respectively, all P<0.05). The changes in the sagittal dimension of the nasopharynx (⊿S) was negatively correlated with angulation in supramental and anatomical horizontal line (⊿SNB) (r=-0.322, P=0.045). The changes in the

    Developmental changes in the coordinative organization of masticatory muscles were examined longitudinally in four children over 49 experimental sessions spanning the age range of 12–48 mo. Electromyographic (EMG) records were obtained for right and left masseter muscles, right and left temporalis muscles, and the anterior belly of the digastric. Two independent analytic processes were employed, one that relied on identification of onset and offset of muscle activation and a second that used pairwise cross-correlational techniques. The results of these two analyses, which were found to be consistent with each other, demonstrated that the basic chewing pattern of reciprocally activated antagonistic muscle groups is established by 12 mo of age. Nevertheless, chewing efficiency appears to be improved through a variety of changes in the chewing pattern throughout early development. Coupling of activity among the jaw elevator muscles was shown to strengthen with maturation, and the synchrony of onset and offset of these muscles also increased. Coactivation of antagonistic muscles decreased significantly with development. This decrease in antagonistic coactivation and increase in synchrony among jaw elevators, and a parallel decrease in EMG burst duration, were taken as evidence of increased chewing efficiency. No significant differences in the frequency of chewing were found across the ages studied. Additional considerations include the appropriateness of this coordinative infrastructure for other developing oromotor skills, such as speech production. It is suggested that the relatively fixed coordinative framework for chewing exhibited by these children would not be suitable for adaptation to speech movements, which have been shown to rely on a much more variable and adjustable coordinative organization.

    Changes in the neighborhood environment may explain part of the rapid increase in childhood overweight and obesity during the last decades. To date few theory-driven rather than data-driven studies have explored longitudinal associations between multiple neighborhood characteristics and child body weight development. We aimed to assess the relationship between physical, social and perceived safety related characteristics of the neighborhood and Body Mass Index (BMI) development in children during early school age, using a longitudinal design. We included an examination of moderating and confounding factors based on a conceptual model adapted from the EnRG framework (Environmental Research framework for weight Gain prevention) and empirical research. Analyses included 1887 children from the KOALA Birth Cohort Study followed from baseline age 4-5 years until 8-9 years. For children age 4-5 years, parents completed a questionnaire measuring characteristics of the neighborhood. Reliability and factor analyses were used to identify constructs for neighborhood characteristics. Linear regression analysis was performed to assess the relationship between neighborhood constructs and BMI z-scores cross-sectionally at age 4-5 years and longitudinally using Generalized Estimating Equations with BMI z-scores over 5 repeated measurements until age 8-9 years. Fourteen constructs were identified and grouped in three domains including perceived physical, social, or safety related characteristics of the neighborhood. Cross-sectionally, a lower BMI z-score was associated with higher perceived physical attractiveness of the neighborhood environment (standardized regression coefficient (β) -0.078, 95% CI -0.123 to -0.034) and a higher level of social capital (β -0.142, -0.264 to -0.019). Longitudinally, similar associations were observed with potentially even stronger regression coefficients. This study suggests that BMI in children is mainly related to the modifiable physical

    The objective of this study was to investigate the prospective relationships between sense of coherence, trait emotional intelligence and children's somatic complaints. The study included four waves of data collection with six months in between each wave. Participants were 324 girls and 393 boys (mean age = 10 years and 3 months, SD = 8.5 months) at the first time of data collection. The children filled out self-report questionnaires concerning their somatic complaints, sense of coherence and trait emotional intelligence. Multilevel model analyses were carried out that included cross-sectional and longitudinal effects of sense of coherence and trait emotional intelligence on children's somatic complaints. The results showed that higher levels of trait emotional intelligence and a stronger sense of coherence were associated with fewer somatic complaints in children. These relationships seemed to be bidirectional.

    The tripartite model of anxiety and depression has been studied with adults; however, support is still emerging with children concerning measurement and relations between positive (PA) and negative (NA) affect and psychopathology. In this longitudinal study of 270 4th- to 11th-grade children (mean age = 12.9 years, SD = 2.23). confirmatory factor analysis supported a 2-factor orthogonal model of children's self-reported affect and revealed that the concurrent relations of NA and PA to anxiety and depression symptoms were consistent with the tripartite model. Structural equation modeling demonstrated moderate cross-time stability of trait PA and NA, consistent with a temperament view of these factors, as well as partial support for the role of NA and PA in the development of anxiety and depression symptoms in children.

    There is a growing body of evidence attesting to links between early life exposure to stress and childhood asthma. However, available evidence is largely based on small, genetically high risk samples. The aim of this study was to explore the associations between the course of maternal depressive symptoms across early childhood and childhood asthma in a nationally representative longitudinal cohort study of Australian children. Participants were 4164 children and their biological mothers from the Longitudinal Study of Australian Children. Latent class analysis identified three trajectories of maternal depressive symptoms across four biennial waves from the first postnatal year to when children were 6-7 years: minimal symptoms (74.6%), sub-clinical symptoms (20.8%), and persistent and increasing high symptoms (4.6%). Logistic regression analyses revealed that childhood asthma at age 6-7 years was associated with persistent and increasing high depressive symptoms after accounting for known risk factors including smoking during pregnancy and maternal history of asthma (adjusted OR 2.36, 95% CI 1.61-3.45), p.001). Our findings from a nationally representative sample of Australian children provide empirical support for a relationship between maternal depressive symptoms across the early childhood period and childhood asthma. The burden of disease from childhood asthma may be reduced by strengthening efforts to promote maternal mental health in the early years of parenting.

    Gaze-based assistive technology (gaze-based AT) has the potential to provide children affected by severe physical impairments with opportunities for communication and activities. This study aimed to examine changes in eye gaze performance over time (time on task and accuracy) in children with severe physical impairments, without speaking ability, using gaze-based AT. A longitudinal study with a before and after design was conducted on 10 children (aged 1-15 years) with severe physical impairments, who were beginners to gaze-based AT at baseline. Thereafter, all children used the gaze-based AT in daily activities over the course of the study. Compass computer software was used to measure time on task and accuracy with eye selection of targets on screen, and tests were performed with the children at baseline, after 5 months, 9-11 months, and after 15-20 months. Findings showed that the children improved in time on task after 5 months and became more accurate in selecting targets after 15-20 months. This study indicates that these children with severe physical impairments, who were unable to speak, could improve in eye gaze performance. However, the children needed time to practice on a long-term basis to acquire skills needed to develop fast and accurate eye gaze performance.

    The purpose of this study was to examine the relation between the ability to quickly acquire initial mental graphemic representations (MGRs) in kindergarten and fourth grade literacy skills in children with typical language (TL) and children with language impairment (LI). The study is a longitudinal extension of a study conducted by Wolter and Apel in which kindergarten children with LI and TL were administered early literacy measures as well as a novel written pseudoword task of MGR learning (spelling and identification of target pseudowords). In the current study (4 years later), the authors administered reading and spelling measures to 37 of the original 45 children (18 children with LI, 19 children with TL). The children with LI performed significantly lower than their peers with TL on all fourth grade literacy measures. For both groups, kindergarten initial MGR acquisition ability significantly related to fourth grade real-word reading and spelling. For the children with LI, kindergarten initial MGR acquisition ability also related to fourth grade pseudoword decoding and reading comprehension. Collectively, the findings suggest that initial MGR learning in kindergarten is an essential skill that may uniquely relate to later literacy abilities.

    ABSTRACT Gaze-based assistive technology (gaze-based AT) has the potential to provide children affected by severe physical impairments with opportunities for communication and activities. This study aimed to examine changes in eye gaze performance over time (time on task and accuracy) in children with severe physical impairments, without speaking ability, using gaze-based AT. A longitudinal study with a before and after design was conducted on 10 children (aged 1–15 years) with severe physical impairments, who were beginners to gaze-based AT at baseline. Thereafter, all children used the gaze-based AT in daily activities over the course of the study. Compass computer software was used to measure time on task and accuracy with eye selection of targets on screen, and tests were performed with the children at baseline, after 5 months, 9–11 months, and after 15–20 months. Findings showed that the children improved in time on task after 5 months and became more accurate in selecting targets after 15–20 months. This study indicates that these children with severe physical impairments, who were unable to speak, could improve in eye gaze performance. However, the children needed time to practice on a long-term basis to acquire skills needed to develop fast and accurate eye gaze performance. PMID:26496529

    These longitudinal studies investigated the cultural mediation of children’s thinking about the Earth using an interview technique designed to elicit responses from children from all “levels” of their conceptual organization (intuitive, cultural, and scientific). Close scrutiny of the research literature in this field reveals that some strategies used in the past to probe children’s ideas have been influenced by the background of the interviewer, either in the design of their questions or in the use made of concrete props (e.g., of the Earth’s shape). This has tended to obscure the degree of cultural influence in those interviewed. Central to the current research was the development of an interview method (“instrument attunement”) that was flexible, culturally adaptable, and could be tuned to the response level of the child. The participants included 129 boys and 113 girls from China, and 217 boys and 227 girls from New Zealand. The methodology utilizing observational astronomy led into discussion of the motion and shape of the Earth, Sun and Moon. Surprisingly, the development of children’s concepts was found to be remarkably similar within the three main ethnic groups (Han, New Zealand European and New Zealand Maori) in the two cultures (China and New Zealand). Cases of cultural mediation were detected using the new methodology but these could be assimilated into a common taxonomy of cosmological concepts for all participants.

    Cisplatin, a major antineoplastic drug used in the treatment of solid tumors, is a known nephrotoxin. This retrospective cohort study evaluated the prevalence and severity of cisplatin nephrotoxicity in 54 children and its impact on height and weight.We recorded the weight, height, serum creatinine, and electrolytes in each cisplatin cycle and after 12 months of treatment. Nephrotoxicity was graded as follows: normal renal function (Grade 0); asymptomatic electrolyte disorders, including an increase in serum creatinine, up to 1.5 times baseline value (Grade 1); need for electrolyte supplementation <3 months and/or increase in serum creatinine 1.5 to 1.9 times from baseline (Grade 2); increase in serum creatinine 2 to 2.9 times from baseline or need for electrolyte supplementation for more than 3 months after treatment completion (Grade 3); and increase in serum creatinine ≥3 times from baseline or renal replacement therapy (Grade 4).Nephrotoxicity was observed in 41 subjects (75.9%). Grade 1 nephrotoxicity was observed in 18 patients (33.3%), Grade 2 in 5 patients (9.2%), and Grade 3 in 18 patients (33.3%). None had Grade 4 nephrotoxicity. Nephrotoxicity patients were younger and received higher cisplatin dose, they also had impairment in longitudinal growth manifested as statistically significant worsening on the height Z Score at 12 months after treatment. We used a multiple logistic regression model using the delta of height Z Score (baseline-12 months) as dependent variable in order to adjust for the main confounder variables such as: germ cell tumor, cisplatin total dose, serum magnesium levels at 12 months, gender, and nephrotoxicity grade. Patients with nephrotoxicity Grade 1 where at higher risk of not growing (OR 5.1, 95% CI 1.07-24.3, P=0.04). The cisplatin total dose had a significant negative relationship with magnesium levels at 12 months (Spearman r=-0.527, P=<0.001).

    Background Generating percentile values is helpful for the identification of children with specific fitness characteristics (i.e., low or high fitness level) to set appropriate fitness goals (i.e., fitness/health promotion and/or long-term youth athlete development). Thus, the aim of this longitudinal study was to assess physical fitness development in healthy children aged 9–12 years and to compute sex- and age-specific percentile values. Methods Two-hundred and forty children (88 girls, 152 boys) participated in this study and were tested for their physical fitness. Physical fitness was assessed using the 50-m sprint test (i.e., speed), the 1-kg ball push test, the triple hop test (i.e., upper- and lower- extremity muscular power), the stand-and-reach test (i.e., flexibility), the star run test (i.e., agility), and the 9-min run test (i.e., endurance). Age- and sex-specific percentile values (i.e., P10 to P90) were generated using the Lambda, Mu, and Sigma method. Adjusted (for change in body weight, height, and baseline performance) age- and sex-differences as well as the interactions thereof were expressed by calculating effect sizes (Cohen’s d). Results Significant main effects of Age were detected for all physical fitness tests (d = 0.40–1.34), whereas significant main effects of Sex were found for upper-extremity muscular power (d = 0.55), flexibility (d = 0.81), agility (d = 0.44), and endurance (d = 0.32) only. Further, significant Sex by Age interactions were observed for upper-extremity muscular power (d = 0.36), flexibility (d = 0.61), and agility (d = 0.27) in favor of girls. Both, linear and curvilinear shaped curves were found for percentile values across the fitness tests. Accelerated (curvilinear) improvements were observed for upper-extremity muscular power (boys: 10–11 yrs; girls: 9–11 yrs), agility (boys: 9–10 yrs; girls: 9–11 yrs), and endurance (boys: 9–10 yrs; girls: 9–10 yrs).

    This study addresses family structure in families raising a child with disabilities in Norway. The aims are to add to the literature on termination of parental relationships and to explore family research topics that are rarely discussed in disability research, such as cohabitation versus marriage and repartnering. Longitudinal survey data on families of children with intellectual and developmental disabilities who were born 1993-1995 were compared with register data on all families of same-aged children (five waves 1999-2012). Parents of children with disabilities had slightly lower termination rates and formalized their partnerships earlier. Furthermore, the rate of repartnering among divorced/separated mothers of young children with disabilities was similar to that of other mothers but decreases later in the child's life course. Results support the view that findings diverge and are most likely dependent on context. © 2015 The Authors.

    Preterm (PT) children show early cognitive and language deficits and display altered cortical connectivity for language compared to term (T) children. Developmentally, functional connectivity networks become more segregated and integrated, through the weakening of short-range and strengthening of long-range connections. Longitudinal intrinsic connectivity distribution (ICD) values were assessed in PT (n = 13) compared to T children (n = 12) at ages 8 vs. 16 using a Linear Mixed Effects model. Connectivity values in regions generated by the group × age interaction analysis were then correlated to scores on full IQ (FSIQ), verbal IQ (VIQ), verbal comprehension IQ (VCIQ), performance IQ (PIQ), Peabody picture vocabulary test-revised (PPVT-R), and Rapid Naming Composite (RDRL_Cmp). Nine regions were generated by the group × age interaction analysis. PT connectivity significantly increased over time in all but two regions, and they ultimately displayed greater relative connectivity at age 16 than Ts in all areas except the left occipito-temporal cortex (OTC). PTs underwent significant connectivity reductions in the left OTC, which corresponded with worse performance on FSIQ, VIQ, and PIQ. These findings differed from Ts, who did not undergo any significant changes in connectivity over time. These findings suggest that the developmental alterations in connectivity in PT children at adolescence are both pervasive and widespread. The persistent and worsening cognitive and language deficits noted in the PT subjects may be attributed to the loss of connections in the left OTC.

    Children with tics often experience accompanying problems that may have more impact on their well being and quality of life than the tics themselves. The present study investigates characteristics and the course of associated problems. In a population-based follow-up study, we investigated the developmental trajectory of children with and without tics when they were 7-9 years old. Parents and teachers completed the strengths and difficulties questionnaire (SDQ) when the children were 7-9 years (wave 1) and 4 years later (wave 2). Using strict criteria, we identified 38 children with tics in the cohort of 4,025 children (0.94% of the total cohort) with a preponderance of boys (78.9%). 22 children (57.9%) in the group with tics had only motor tics, and 16 (42.1%) had both motor and vocal tics. Children with tics had significantly higher parent- and teacher-rated SDQ total difficulty scores and subscale scores in both waves. Children with tics experienced an increase in emotional problems and in peer problems between the first and the second wave. This study in a general population indicates that the presence of tics is associated with a range of internalizing and externalizing difficulties, as well as problems in peer relationships. Moreover, our study indicates that emotional and peer problems tend to increase over time in the group of children with tics.

    Epidemiological evidence from developed countries indicates that Helicobacter pylori infection correlates with a reduced risk of atopy and allergic disorders; however, limited data are available from low-income countries. We examined associations between H. pylori infection in early childhood and atopy and reported allergic disorders at the age of 6.5 years in an Ethiopian birth cohort. A total of 856 children (85.1% of the 1006 original singletons in a population-based birth cohort) were followed up at age six and half years. An interviewer-led questionnaire administered to mothers provided information on demographic and lifestyle variables. Questions on allergic disease symptoms were based on the International Study of Asthma and Allergies in Children (ISAAC) core allergy and environmental questionnaire. Serum samples were analysed for total IgE levels and anti-H. pylori cytotoxin-associated gene A (CagA) IgG antibody using commercially available ELISA kits. Stool samples were analysed for H. pylori antigen using a rapid immunochromatographic test. The independent effects of H. pylori infection (measured at age of 3, 5 and 6.5 years) on prevalence and incidence of atopy and reported allergic disorders (measured at age of 6.5 years) were determined using multiple logistic regression. In cross-sectional analysis, current H. pylori infection at age 6.5 years was inversely, though not significantly, related to prevalence of atopy and "any allergic condition" at age 6.5 years. However, detection of H. pylori infection at any point up to age 6.5 years was associated with a significantly reduced odds of both atopy and "any allergic condition" (adjusted OR AOR, 95% CI, 0.54; 0.32-0.92, P = .02, and .31; 0.10-0.94, P = .04, respectively). In longitudinal analyses, H. pylori infection at age 3 was inversely associated with incidence of atopy (AOR, 95% CI, 0.49; 0.27-0.89, P = .02). Furthermore, among H. pylori-infected children, those with a Cag

    Exclusion from school is increasingly recognized as pertinent to child health. National educational data reveal that boys, children who are looked-after, living in poverty, have special educational needs, or from certain ethnic minorities, are disproportionately excluded from school. As population-based data on the wider characteristics of excluded children are scarce, we aimed to describe predictors of school exclusion in the Avon Longitudinal Study of Parents and Children. Avon Longitudinal Study of Parents and Children, a prospective U.K. population-based birth cohort study, collected parent reports of permanent school exclusions by 8 years and parent and self-reports of permanent and fixed-term exclusions in the preceding 12 months at 16 years. Potential risk factors were examined for associations with exclusion using logistic regression, with a focus on child mental health and neurodevelopment. Analyses were based on all available data on 53/8,245 (0.6%) pupils excluded from school by 8 years and 390/4,482 (8.7%) at 16 years. Key factors associated with exclusion at both time points included male gender, lower socio-economic status, maternal psychopathology, mental health and behavioural difficulties, psychiatric disorder, social communication difficulties, language difficulties, antisocial activities, bullying/being bulled, lower parental engagement with education, low school engagement, poor relationship with teacher, low educational attainment, and special educational needs (all p < .05). Exclusion from school was associated with child, family and school-related factors identifiable at, or prior to, primary school age. Child health professionals have an important role in the holistic, multidisciplinary assessment of children who are at risk of exclusion from school. Mental health and neurodevelopmental difficulties should be recognized and supported, to improve the health and educational outcomes among this vulnerable group. © 2017 John Wiley & Sons

    Cryptosporidiosis is a common cause of infectious diarrhea in young children worldwide, and is a significant contributor to under-five mortality. Current treatment options are limited in young children. In this study, we describe the natural history of Cryptosporidium spp. infection in a birth cohort of children in Bangladesh and evaluate for association with malnutrition. This is a longitudinal birth cohort study of 392 slum-dwelling Bangladeshi children followed over the first two years of life from 2008 to 2014. Children were monitored for diarrheal disease, and stool was tested for intestinal protozoa. Anthropometric measurements were taken at 3-month intervals. A subset of Cryptosporidium positive stools were genotyped for species and revealed that C. hominis was isolated from over 90% of samples. In the first two years of life, 77% of children experienced at least one infection with Cryptosporidium spp. Non-diarrheal infection (67%) was more common than diarrheal infection (6.3%) although 27% of children had both types of infection. Extreme poverty was associated with higher rates of infection (chi-square, 49.7% vs 33.3%, p = 0.006). Malnutrition was common in this cohort, 56% of children had stunted growth by age two. Children with Cryptosporidium spp. infection had a greater than 2-fold increased risk of severe stunting at age two compared to uninfected children (odds ratio 2.69, 95% CI 1.17, 6.15, p = 0.019) independent of sex, income, maternal body-mass index, maternal education and weight for age adjusted z (WAZ) score at birth. Cryptosporidium infection is common (77%) in this cohort of slum-dwelling Bangladeshi children, and both non-diarrheal and diarrheal infections are significantly associated with a child's growth at 2 years of age.

    Maxillary sinus volumetric and surface area data and growth models from longitudinal samples of children and adolescents are presented. Cone-beam radiographic CT scans from two small retrospective longitudinal samples, one from the Baylor College of Dentistry, Dallas, TX (N=17, 12 females, 5 males, 10.9-17.4 years) and one from a group private orthodontic practice in Nevada (N=15, 9 females, 6 males, 6.4-13.4 years) were used to collect maxillary sinus volumes and surface areas from each individual imaged at two times separated by variable intervals. Volume and surface area values were collected in Analyze(®) (Mayo Clinic) and growth models were produced in MLwiN(®), a multi-level modeling program. There is a large degree of inter-individual variation. Surface area and surface-area-to-volume ratio (SA:V) changes are particularly variable. Growth models suggest linear growth in both volume and surface area, without growth spurts. Copyright © 2016 Elsevier GmbH. All rights reserved.

    To examine the relation between pertussis vaccination and the prevalence of wheezing illnesses in young children. Prospective cohort study. Three former health districts comprising Avon Health Authority. 9444 of 14 138 children enrolled in the Avon longitudinal study of pregnancy and childhood and for whom data on wheezing symptoms, vaccination status, and 15 environmental and biological variables were available. Episodes of wheezing from birth to 6 months, 7-18 months, 19-30 months, and 31-42 months. These time periods were used to derive five categories of wheezing illness: early wheezing (not after 18 months); late onset wheezing (after 18 months); persistent wheezing (at every time period); recurrent wheezing (any combination of two or more episodes for each period); and intermittent wheezing (any combination of single episodes of reported wheezing). These categories were stratified according to parental self reported asthma or allergy. Unadjusted comparisons of the defined wheezing illnesses in vaccinated and non-vaccinated children showed no significant association between pertussis vaccination and any of the wheezing outcomes regardless of stratification for parental asthma or allergy. Wheeze was more common in non-vaccinated children at 18 months, and there was a tendency for late onset wheezing to be associated with non-vaccination in children whose parents did not have asthma, but this was not significant. After adjustment for environmental and biological variables, logistic regression analyses showed no significant increased relative risk for any of the wheezing outcomes in vaccinated children: early wheezing (0.99, 95% confidence interval 0.80 to 1.23), late onset wheezing (0.85, 0.69 to 1.05), persistent wheezing (0.91, 0.47 to 1.79), recurrent wheezing (0.96, 0.72 to 1.26), and intermittent wheezing (1.06, 0.81 to 1.37). No evidence was found that pertussis vaccination increases the risk of wheezing illnesses in young children. Further follow

    The increasing prevalence of childhood overweight is an important health issue. There is a need for longitudinal research among children in order to identify risk factors for childhood overweight. The objective of the present research was to identify potential sociodemographic and behavioural risk factors for development of childhood overweight among 3- to 6-year-old children. Longitudinal study. Sixteen pre-primary and primary schools. BMI Z-scores at baseline and two follow-up measurements were calculated for 568 children. Sociodemographic, parental adiposity, familial composition, child's diet, physical activity and sedentary behavioural data were collected through questionnaires. Several risk factors for the development of childhood overweight were found. Being an only child, lower maternal educational level, maternal and paternal overweight, more than 1 h screen time on weekdays and high soft drinks consumption were shown to be positively associated with the development of childhood overweight. Although behavioural factors are important, our findings support the thesis that interventions on the prevention of childhood overweight should focus on high-risk groups, i.e. children from low socio-economic background or with high parental BMI. Interventions should address the whole family and take into account their lifestyle and structure.

    Although sleep disturbances are commonly reported among children exposed to violence, objective evidence of such disturbances is rare. This longitudinal, home-based study assessed the effects of a known community- or family-violence incident on both actigraphy-derived and subjectively reported sleep outcomes of an ethnically mixed, urban sample of children aged 8-16 years. We hypothesized that increased event severity (child physical assault, witnessed homicide) would be associated with lower sleep duration and poorer sleep quality both at baseline and at 3-month follow-up. Covariate-adjusted analyses based on a generalized estimating equations approach showed that children physically assaulted during the event showed lower sleep duration and sleep efficiency and greater wake after sleep onset than those not physically assaulted. Physically assaulted children were more likely to have a later bedtime than non-assaulted children, but this difference decreased at 3 months. Children witnessing a homicide showed greater wake after sleep onset at baseline and reported greater sleep problems than those witnessing a non-homicide event, but these differences decreased at 3 months. They were also somewhat more likely to have greater nightly variation in sleep duration. Collectively, results suggest that violence exposure influences children's sleep, but that specific dimensions of sleep may exhibit different susceptibility to different characteristics of violence, especially over time.

    Over the past decade, educators and researchers concerned about children with reading disabilities have called for widespread adoption of early identification tools and early effective programming. This call may be the result of, in part, what Stanovich calls "Matthew effects in reading." That is, when stakeholders delay identification and support for young children struggling to read, the variance of individual differences in reading will inevitably increase, creating a widening of the gap between strong and struggling readers. In this longitudinal study, reading achievement data from 382 children were collected as they progressed from kindergarten through Grade 3. In kindergarten, children were screened with a battery of phonological awareness measures. Percentile rank scores were collected, and children were identified as having poor, average, or strong phonological awareness. As children moved through Grades 1, 2, and 3, reading-based data were collected in the spring of each year. Results indicated that, in general, as children progressed from kindergarten to Grade 3, those in lower ranks of reading achievement were likely to remain in the lower ranks, and furthermore, at each progressing data collection point struggling readers fell further behind their grade-level reading peers. In other words, as each year passed the variance between strong and struggling readers increased significantly. The authors hypothesized that this finding is consistent with the "Matthew effect"-the rich were getting richer while the poor were getting poorer.

    The relationship between obesity and academic outcomes remains unclear. We evaluated the association between obesity and cognitive performance in US children. We analyzed two nationally representative prospective cohorts of children in the 1979 National Longitudinal Survey of Youth, ages 2 through 8 at baseline and followed for 6 years, from 1988 to 1994 (cohort 1, n=2672) and 1994 to 2000 (cohort 2, n=1991). The main exposure variable was obesity (defined as never obese, became obese, always obese, and became nonobese). The main outcomes were standardized scores on four cognitive assessments. Univariate regression analyses of test scores on obesity were performed. Fixed-effects regression models, controlling for measured and unmeasured time-invariant confounders, were additionally adjusted for time-variant confounders to analyze the impact of change in obesity status on change in test scores. Unadjusted analyses revealed a significant association between obesity and Peabody Individual Achievement Test (PIAT) scores. In cohort 1, always obese children had lower PIAT math scores than never obese children (β=-7.48; p<0.05). Always obese boys had lower PIAT math scores than those who were never obese (β=-16.45; p<0.01). In cohort 2, PIAT math scores were lower in the became obese category than the never obese category (β=-4.10; p<0.05). Always obese girls had lower PIAT reading scores than those who were never obese (β=-11.28; p<0.01). Fixed-effects models additionally adjusted for Home Observation Measurement of the Environment, Short Form score and height percentile showed no significant relationship between obesity and test scores in either cohort. Childhood obesity is unlikely to be causally related to cognitive performance.

    A longitudinal study examined the relations of maternal autonomy support to children's school adjustment. Autonomy support and other parenting dimensions were measured when children were 5 years old. School measures were teacher-rated academic and social adjustment and achievement in reading and math in grade 3. Regression analyses controlling for age 5 family and child factors (e.g., socioeconomic status [SES], kindergarten adjustment, IQ) revealed that autonomy support was positively related to grade 3 adjustment (social and academic) and reading achievement. Maternal emphasis on school performance was positively related to achievement measures but negatively related to social adjustment. Maternal use of rewards and praise was unrelated to grade 3 school measures. Finally, supplemental analyses revealed that autonomy support was associated with greater consistency in children's adjustment across social and academic domains as well as higher overall adjustment. These results highlight the developmental significance of parental autonomy support in early childhood.

    There is strong empirical evidence that English-speaking children with spoken language difficulties (SLD) often have phonological awareness (PA) deficits. The aim of this study was to explore longitudinally if this is also true of pre-school children speaking German, a language that makes extensive use of derivational morphemes which may impact on the acquisition of different PA levels. Thirty 4-year-old children with SLD were assessed on 11 PA subtests at three points over a 12-month period and compared with 97 four-year-old typically developing (TD) children. The TD-group had a mean percentage correct of over 50% for the majority of tasks (including phoneme tasks) and their PA skills developed significantly over time. In contrast, the SLD-group improved their PA performance over time on syllable and rhyme, but not on phoneme level tasks. Group comparisons revealed that children with SLD had weaker PA skills, particularly on phoneme level tasks. The study contributes a longitudinal perspective on PA development before school entry. In line with their English-speaking peers, German-speaking children with SLD showed poorer PA skills than TD peers, indicating that the relationship between SLD and PA is similar across these two related but different languages.

    The purpose of this study was to compare the Pediatric Evaluation of Disability Inventory (PEDI) and the Mullen Scales of Early Learning (MSEL) as measures of change in children who received early intervention services. Thirty-four children were stratified into 2 groups according to the presence of gross motor delay. The PEDI and MSEL were administered 3 times: at an average age of 18, 31, and 53 months of age. Data were analyzed using a repeated-measures multivariate analysis of variance. The findings suggest that PEDI Functional Skills Scaled Scores were capable of measuring change in both groups of children. The standard scores on the PEDI Functional Skills Social Scale were found to be more sensitive to change than the MSEL Receptive and Expressive Language scores for children with motor delays. Using PEDI scaled scores may be an effective strategy for measuring change in children receiving early intervention services.

    Maillart and Parisse found out that French children with specific language impairment (SLI) presented strong difficulties in phonology when compared with normally-developing children matched by MLU (NLD). Some of the youngest children from this study were followed to provide developmental information about their language deficit. Children were tested again in the same way as before (free spontaneous production) and matched by MLU against other NLD children. The previous phonological analysis was extended to include syntax as well as phonology. Percentage of words correct was computed for both phonology and syntax. An analysis of covariance (ANCOVA) was performed with children's age as covariate. Results showed a significant difference between SLI and NLD children for phonology but not for syntax. There was a trend that showed that the difference between SLI and NLD children tended to increase with age. The same analysis was performed separately for 9 frequent syntactic categories for phonology and for syntax. A significant difference was found for prepositions, nouns, subject pronouns, and verbs in phonology. Effects were found for determiners and prepositions in syntax. As well as confirming the importance of phonological difficulties in SLI, our results call for a developmental theory of phonological and syntactic deficits in SLI, where differences between SLI and NLD grow with age and where there is a timing difference between phonology (earlier) and syntax (later).

    This study aimed to describe refugee children, their families and settlement characteristics, and how their development and social-emotional well-being change over time. We conducted a longitudinal study of 61 refugee children (6 months to 15 years) in an Australian setting, over 2009-2013 and measured child, family and settlement factors as well as physical health, development and social-emotional well-being (Strengths and Difficulties Questionnaire, SDQ). Questionnaires were completed with parents of 54 (89%) children at year 2 and 52 (100%) at year 3. Forty percent of parents had low levels of education, 30% of fathers were absent on arrival, 13% of children were born in refugee camps and 11% of parents self-disclosed previous trauma. Over time, there was increased parental employment (P = 0.001), improved English proficiency for partners (P = 0.02) and reduced stressful life events in the last 12 months (P = 0.003). At years 2 and 3, parents were studying English (96%; 76%), accessing government financial support (96%; 100%) and primary health care (98%; 87%), and feeling supported by their own (78%; 73%) or the general (69%; 63%) community. Fifteen percent of children had a chronic disease, and 13% were obese and overweight. In pre-school children, 27% had mild developmental problems in year 2; all were normal by year 3. Abnormal SDQ total difficulties scores reduced over time from 13 to 6% of children but this did not reach significance. Most refugee children have developmental and well-being outcomes within the normal range by year 3. However, a minority of children have persistently poor social-emotional outcomes. © 2017 Paediatrics and Child Health Division (The Royal Australasian College of Physicians).

    Few prospective studies have examined school mobility in children in foster care. This study described the school moves of 86 such children and 55 community comparison children (primarily Caucasian), living in a medium-sized metropolitan area in the Pacific Northwest who were approximately 3-6-years-old at the study start. Additionally, the effects of moves from kindergarten through Grade 2 on academic and social emotional competence in Grades 3 through 5 were examined. A greater number of early school moves was associated with poorer later social emotional competence and partially mediated the effects of maltreatment and out-of-home placement on social emotional competence. This was only the case for children with poorer early learning skills in kindergarten. Implications for preventive intervention are discussed. PMID:25906815

    Our aim was to examine the degree to which changes in BMI percentile reflect changes in body fat and lean body mass during childhood and how age and gender affect these relationships. This analysis used serial data on 494 white boys and girls who were aged 8 to 18 years and participating in the Fels Longitudinal Study (total 2319 observations). Total body fat (TBF), total body fat-free mass (FFM), and percentage of body fat (%BF) were determined by hydrodensitometry, and then BMI was partitioned into its fat and fat-free components: fat mass index (FMI) and FFM index (FFMI). We calculated predicted changes (Delta) in FMI, FFMI, and %BF for each 10-unit increase in BMI percentile using mixed-effects models. FFMI had a linear relationship with BMI percentile, whereas FMI and %BF tended to increase dramatically only at higher BMI percentiles. Gender and age had significant effects on the relationship between BMI percentile and FFMI, FMI, and %BF. Predicted Delta%BF for boys 13 to 18 years of age was negative, suggesting loss of relative fatness for each 10-unit increase in BMI percentile. In this longitudinal study of white children, FFMI consistently increased with BMI percentile, whereas FMI and %BF had more complicated relationships with BMI percentile depending on gender, age, and whether BMI percentile was high or low. Our results suggest that BMI percentile changes may not accurately reflect changes in adiposity in children over time, particularly among male adolescents and children of lower BMI.

We found that musician children outperformed non-musician children only on musical achievement and second language development. Additionally, although music training appeared to be correlated with children's final academic development of L1, L2, and mathematics, it did not independently contribute to the development of L1 or mathematical skills. Our findings suggest caution in interpreting the positive findings on the non-musical cognitive benefits of music learning. PMID:25068398

    2017-01-01

    Background: Prospective longitudinal studies are essential in characterizing cognitive trajectories, yet few of them have been reported on the development of attention processes in children. We aimed to explore attention development in normal children and children with attention deficit and hyperactivity disorder (ADHD) symptoms in a repeated measures design using the attention network test (ANT). Methods: The population sample included 2,835 children (49.6% girls) aged 7-11 years from 39 schools in Barcelona (Catalonia, Spain) who performed the ANT four times from January 2012 to March 2013. According to teacher ratings, 10.5% of the children presented ADHD symptoms. We performed multilevel mixed-effects linear regression models, adjusting for school and individual, to test the effects of age-related growth on the ANT networks: alerting, orienting and executive attention, and three measurements related to attentiveness: median of hit reaction time (HRT), hit reaction time standard error (HRT-SE) and variability. Results: We observed age-related growth in all the outcomes, except orienting. The curves were steeper at the younger groups, although for alertness the improvement was further at the oldest ages. Gender and ADHD symptoms interacted with age in executive attention, HRT and variability. Girls performed better in executive attention at young ages although boys reached females at around 10 years of age. For HRT, males showed faster HRT. However, girls had a more pronounced improvement and reached the levels of boys at age 11. Children with ADHD symptoms had significant differences in executive attention, HRT and variability compared to children without ADHD symptoms. Conclusions: We detected an ongoing development of some aspects of attention in primary school children, differentiating patterns by gender and ADHD symptoms. Our findings support the ANT for assessing attention processes in children in large epidemiological studies.

  8. Designing and implementing a longitudinal study of children with neurological, genetic or metabolic conditions: charting the territory

    PubMed Central

    2010-01-01

    Background Children with progressive metabolic, neurological, or chromosomal conditions and their families anticipate an unknown lifespan, endure unstable and often painful symptoms, and cope with erratic emotional and spiritual crises as the condition progresses along an uncertain trajectory towards death. Much is known about the genetics and pathophysiology of these diseases, but very little has been documented about the trajectory of symptoms for children with these conditions or the associated experience of their families. A longitudinal study design will help to close this gap in knowledge. Methods/Design Charting the Territory is a longitudinal descriptive, correlational study currently underway with children 0-19 years who are diagnosed with progressive neurological, metabolic, or chromosomal conditions and their families. The purpose of the study is to determine and document the clinical progression of the condition and the associated bio-psychosocial-spiritual experiences of the parents and siblings age 7-18 years. Approximately 300 families, both newly diagnosed children and those with established conditions, are being recruited in six Canadian cities. Children and their families are being followed for a minimum of 18 months, depending on when they enroll in the study. Family data collection will continue after the child's death if the child dies during the study period. Data collection includes monthly parental assessment of the child's symptoms; an annual functional assessment of the child; and completion of established instruments every 6 months by parents to assess family functioning, marital satisfaction, health status, anxiety, depression, stress, burden, grief, spirituality, and growth, and by siblings to assess coping and health. Impact of participation on parents is assessed after 1 year and at the end of the study. Chart reviews are conducted at enrollment and at the conclusion of the study or at the time of the child's death. Discussion

    To compare children's food preferences longitudinally and identify factors related to food preferences. Mothers completed the Food Preference Questionnaire for children at 2 to 3 years of age (T1), 4 years (T2), and 8 years (T3) and for themselves at T1 and T3. Both groups completed a Food Neophobia Scale at T3. 70 child/mother pairs who had participated continuously in the longitudinal study. Changes in food preferences over time were tested with paired t tests and correlations. Consistency percentages were calculated by summing the consistent matches (like/like) for each food between two time periods. Similarly, concordance percentages were calculated for child/mother pairs by summing the concordant matches for each food. General linear models were developed to identify influences on children's food preferences. Although children liked most foods, the number of liked foods did not change significantly during the 5 to 5.7 years of the study. The strongest predictors of the number of foods liked at age 8 years (R2=0.74) were the number liked at 4 years (P<.0001) and the food neophobia score (P=.0003). Newly tasted foods were more likely to be accepted between T1 and T2 than T2 and T3. Mothers' and children's food preferences were significantly but moderately related. Foods disliked by mothers tended not to be offered to children. The important role of children's early food preferences is confirmed by this study. Mothers influence children via their own preferences, which may limit foods offered to children.

    Objective To examine the association between exposure to traffic-related air pollution (TRAP) and hospital readmission for asthma or bronchodilator-responsive wheezing. Study design A population-based cohort of 758 children ages 1–16 years, admitted for asthma or bronchodilator-responsive wheezing was assessed for asthma readmission within 12 months. TRAP exposure was estimated using a land use regression model using the home address at index admission; TRAP was dichotomized at the sample median (0.37 μg/m3). Covariates included allergen-specific IgE, tobacco smoke exposure, and social factors obtained at enrollment. Associations between TRAP exposure and readmission were assessed using logistic regression and Cox proportional hazards. Results Study participants were 58% were African American (AA), 32% white; 19% were readmitted within 12 months. Children with higher TRAP exposure were readmitted at a higher rate overall (21% v. 16%, p = 0.05); this association was not significant after adjusting for covariates (adjusted OR 1.4; 95% CI 0.9–2.2). Race modified the observed association: white children with high TRAP exposure had three-fold increased odds of asthma readmission (OR 3.0; 95% CI 1.1–8.1), compared with low exposed whites. TRAP exposure among AA children was not associated with increased readmission (OR.1.1; 95% CI 0.6–1.8). TRAP exposure was associated with decreased time to readmission for high TRAP-exposed white children (HR 3.2; 95% CI 1.5–6.7) vs. AA children (HR 1.0; 95% CI 0.7–1.4); AA children had a higher readmission rate overall. Conclusions TRAP exposure is associated with increased odds of readmission in white children; this relationship was not observed in AA children. PMID:24680015

    Previous findings regarding the prevalence and predictive value of weak language skills in preterm children with very low birth weight (VLBW) are unclear. This study analysed the prevalence of weak language skills, the predictive value of early weak language skills on later weak language skills, and the sensitivity and specificity of cognitive scores for identifying concurrent weak language skills in a longitudinal sample of VLBW children (n = 141) and their full-term controls (n = 146). Data on language skills and cognitive development were gathered at two and five years of age. Weak language skills were defined by the 10th percentile value of the controls. In VLBW children, the prevalence of weak language skills varied between 16% and 18% at 2 years of age (controls: 8 to 10%) and between 20% and 27% at 5 years of age (controls: 10%). Early weak language skills predicted later weak language skills in VLBW children. Cognitive scores were specific, but their sensitivity for identifying concurrent weak language skills was low. The prevalence of weak language skills in VLBW children increased during the follow-up period and was higher than the controls. Language-sensitive methods should be used in the clinical follow-up of VLBW children.

    Study objectives: To (1) clarify the epidemiology of bad dreams in children and investigate risk and protective factors related to (2) the child's sleep, (3) parental sleep-enabling practices, and (4) the child's temperament. Design: Longitudinal with 6 time points from 5 months to 6 years. Setting: Subjects' homes. Participants: Representative sample of 987 children in the Province of Quebec. Interventions: None. Measurements and Results: Longitudinal logistic regression analysis models with primary endpoints of presence or absence of parent-rated bad dreams at 29 months, 41 months, 50 months, 5 years, and 6 years and predictor variables of demographic characteristics, parent ratings of child's sleep characteristics, parental sleep-enabling practices (e.g., cosleeping), and child's psychological characteristics at 5 and 17 months (anxiousness, temperament). Mothers' ratings indicated lower than expected prevalence of frequent bad dreams (1.3% to 3.9%). Demographic correlates of bad dreams were high family income, absence of siblings at 29 months, and a non-immigrant mother. The best predictor at 41 and 50 months was the presence of bad dreams the preceding year, whereas at 5 and 6 years, it was their earlier presence at 29 months. Early protective factors were parental practices favoring emotional nurturance after night awakenings (29 and 41 months); early risk factors were sleep-onset emotional nurturance (29 months), difficult temperament (5 months), and anxiousness (17 months). Conclusions: Bad dreams in preschoolers are less prevalent than thought but, when present, are trait-like in nature and associated with personality characteristics measured as early as 5 months. A stress-diathesis model may best account for the observed pattern of predictive factors. Citation: Simard V; Nielsen TA; Tremblay RE; Boivin M; Montplaisir JY.

    To determine the accuracy of the caries risk assessment system and performance of clinicians in their attempts to predict caries for children during routine practice. Longitudinal study. Data on caries risk assessment conducted by clinicians during routine practice while providing care for children in the South Australian School Dental Service (SA SDS) were collected from electronic patient records. Baseline data on caries experience, clinicians' ratings of caries risk status and child demographics were obtained for all SA SDS patients aged 5-15 years examined during 2002-2005. Children's caries incidence rate, calculated using examination data after a follow-up period of 6-48 months from baseline, was used as the gold standard to compute the sensitivity (Se) and specificity (Sp) of clinicians' baseline ratings of caries risk. Multivariate binomial regression models were used to evaluate effects of children's baseline characteristics on Se and Sp. A total of 133 clinicians rated caries risk status of 71 430 children during 2002-2005. The observed Se and Sp were 0.48 and 0.86, respectively (Se+Sp=1.34). Caries experience at baseline was the strongest factor influencing accuracy in multivariable regression model. Among children with no caries experience at baseline, overall accuracy (Se+Sp) was only 1.05, whereas it was 1.28 among children with at least one tooth surfaces with caries experience at baseline. Clinicians' accuracy in predicting caries risk during routine practice was similar to levels reported in research settings that simulated patient care. Accuracy was acceptable in children who had prior caries experience at the baseline examination, while it was poor among children with no caries experience.

    When undergoing chemotherapy and/or radiotherapy, children with acute lymphocytic leukemia may present important nutritional disorders because of the gastrointestinal toxicity of most chemotherapy agents or the effects of radiation on the organism. These patients may also present changes in their serum concentrations of trace elements such as zinc and copper. The present study aimed to follow anthropometric parameters and serum levels of zinc and copper in a group of children under treatment for acute lymphocytic leukemia. Longitudinal study, at the Pediatric Section of Hospital das Clínicas, Ribeirão Preto, Brazil. Forty-five children with acute lymphocytic leukemia were studied. Anthropometric parameters such as weight and height and the daily intakes and serum levels of copper and zinc were recorded at diagnosis and during the treatment. During the initial phase of the treatment, there was an increase in energy intake accompanied by weight gain. However, during the later phases of treatment there was a reduction in energy intake with accompanying weight loss. Decreased growth rate during treatment was more pronounced in children with high-risk acute lymphocytic leukemia, probably due to radiation therapy. Serum zinc levels remained basically unaltered during the treatment, whereas copper levels decreased dramatically with the beginning of treatment. The treatment given to children with acute lymphocytic leukemia has an important effect on their linear growth rate and nutritional status, and also on their serum copper levels.

    Chaotic home lives are correlated with behavior problems in children. In the study reported here, we tested whether there was a cross-lagged relation between children's experience of chaos and their disruptive behaviors (conduct problems and hyperactivity-inattention). Using genetically informative models, we then tested for the first time whether the influence of household chaos on disruptive behavior was environmentally mediated and whether genetic influences on children's disruptive behaviors accounted for the heritability of household chaos. We measured children's perceptions of household chaos and parents' ratings of children's disruptive behavior at ages 9 and 12 in a sample of 6,286 twin pairs from the Twins Early Development Study (TEDS). There was a phenotypic cross-lagged relation between children's experiences of household chaos and their disruptive behavior. In genetically informative models, we found that the effect of household chaos on subsequent disruptive behavior was environmentally mediated. However, genetic influences on disruptive behavior did not explain why household chaos was heritable.

    Objective To study the growth of children with complete unilateral cleft lip and palate (UCLP) from birth to 2 years of age and to construct specific UCLP growth curves. Design Physical growth was a secondary outcome measure of a NIH sponsored longitudinal, prospective clinical trial involving the University of Florida (USA) and the University of São Paulo (Brazil). Patients 627 children with UCLP, nonsyndromic, both genders. Methods Length, weight, and head circumference were prospectively measured for a group of children enrolled in a clinical trial. Median growth curves for the 3 parameters (length, weight, head circumference) were performed and compared to the median for the National Center for Health Statistics (NCHS, 2000) curves. The median values for length, weight, and head circumference at birth, 6, 12, 18 and 24 month of age were plotted against NCHS median values, and statistically compared at birth and 24 months. Setting Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru, Brazil (HRAC-USP). Results At birth, children of both genders with UCLP presented with smaller body dimensions in relation to NCHS median values, but the results suggest a “catch up growth” for length, weight, and head circumference for girls and for weight (to some degree) and head circumference for boys. Conclusions Weight was the most compromised parameter for both genders followed by length and then head circumference. There was no evidence of short statue. This study established growth curves for children with UCLP. PMID:19860503

    To examine sex differences in nutritional status in relation to feeding practices over time in a cohort of HIV-exposed children participating in a complementary feeding programme in Rwanda. We applied a longitudinal design with three measurements 2-3 months apart among infants participating in a complementary feeding programme who were 6-12 months old at baseline. Using early feeding practices and a composite infant and child feeding index (ICFI) as indicators of dietary patterns, we conducted a multivariate analysis using a cross-sectional time series to assess sex differences in nutritional status and to determine whether there was a link to discrepancies in dietary patterns. Among 222 boys and 258 girls, the mean (±SD) Z-score of stunting, wasting and underweight was -2.01 (±1.59), -0.15 (±1.46), -1.19 (±1.29) for boys; for girls they were -1.46 (±1.56), 0.22 (±1.29), -0.63 (±1.19); all sex differences in all three indicators were statistically significant (P < 0.001). However, there were only minor differences in early feeding practices and none in the ICFI by sex. HIV-exposed male children may be at higher risk of malnutrition in low-resource setting countries than their female counterparts. However, at least in a setting where complementary foods are being provided, explanations may lie outside the sphere of dietary patterns. © 2014 John Wiley & Sons Ltd.

    To evaluate longitudinally the effectiveness of a cooking programme on self-reported confidence about cooking skills and food consumption patterns in parents of young children. An evaluation of cooking programmes delivered by National Health Service (NHS) community food workers using a single group pre-test/post-test repeated measures design. A shortened version of a validated questionnaire at baseline, post intervention and 1-year follow-up determined confidence in cooking using basic ingredients, following a simple recipe, tasting new foods, preparing and cooking new foods on consumption of ready meals, vegetables and fruit. Deprived communities in Ayrshire and Arran, Scotland. Parents of nursery age children, 97 % were female and <45 years old. One hundred and two participants had completed baseline and post-intervention questionnaires. Forty-four participants contacted by telephone completed a follow-up questionnaire. In participants who completed all questionnaires (n 44), median confidence in four aspects of cooking increased significantly from baseline to post intervention (P < 0·001) but was retained at 1-year follow-up only for following a simple recipe and preparing and cooking new foods. Improved food consumption patterns were reported from baseline to post intervention (ready-meal consumption reduced from 2-4 times/week to 1 time/week, P < 0·001; vegetable consumption increased from 5-6 times/week to 1 time/d, P < 0·001; fruit consumption increased from 5-6 times/week to 1 time/d, P < 0·001) and remained at 1-year follow-up. The cooking programmes appeared to improve cooking confidence and food consumption patterns in the target group and some of these changes were retained after 1 year.

    This study examined the production and perception of English fricatives by native Japanese (NJ) adults and children (16 per group, mean age=40 and 10 years), and age-matched native English (NE) adults and children (16 per group). The subjects were tested two times (T1, T2) 1 year apart. (At T1, the NJ subjects' mean length of residence in the U.S. was 0.5 year.) A picture-naming task was used to elicit the production of English words beginning with /s/ and /θ/, and intelligibility scores were obtained for both. The intelligibility scores of the NJ children but not adults improved significantly from T1 to T2. The NJ children obtained significantly lower scores than the NJ adults did at T1, but at T2 the adult-child difference was nonsignificant. The perception of /s/ and /θ/ was tested by a categorial discrimination task. Although the NJ adult's and children's scores improved from T1 to T2, the T1-T2 differences were nonsignificant. Thus, the results showed that the NJ children's production scores improved significantly from T1 to T2, while there was no significant change for the perception scores on the discrimination of /s/-/θ/. The relationship between production and perception in L2 speech learning will be discussed. [Work supported by NIH.

    The Avon Longitudinal Study of Parents and Children (ALSPAC) is a transgenerational prospective observational study investigating influences on health and development across the life course. It considers multiple genetic, epigenetic, biological, psychological, social and other environmental exposures in relation to a similarly diverse range of health, social and developmental outcomes. Recruitment sought to enroll pregnant women in the Bristol area of the UK during 1990-92; this was extended to include additional children eligible using the original enrollment definition up to the age of 18 years. The children from 14541 pregnancies were recruited in 1990-92, increasing to 15247 pregnancies by the age of 18 years. This cohort profile describes the index children of these pregnancies. Follow-up includes 59 questionnaires (4 weeks-18 years of age) and 9 clinical assessment visits (7-17 years of age). The resource comprises a wide range of phenotypic and environmental measures in addition to biological samples, genetic (DNA on 11343 children, genome-wide data on 8365 children, complete genome sequencing on 2000 children) and epigenetic (methylation sampling on 1000 children) information and linkage to health and administrative records. Data access is described in this article and is currently set up as a supported access resource. To date, over 700 peer-reviewed articles have been published using ALSPAC data.

    Acquired melanocytic naevi (MN) are considered a risk factor for melanoma. Exposure to ultraviolet light (UV) is the major environmental factor for MN. UV protection is most critical in pre-school children. This 3-year interventional longitudinal study examined 395 3-year-old children attending daycare centres (DCC) in Dresden, Germany. Photo-skin type, eye and hair colour were recorded. DCC were randomly assigned to a control group and a behavioural intervention group. All children had a regular naevus check-up, including digital objective analysis with Dell'Eva-Burroni Dermoscopy Melanoma Image Processing Software (DB-MIPS) technology. Parents of children in the intervention group received additional guidance for sun-protection. The mean total MN counts of both groups at the start of the study period were 7.19 ± 4.55 (intervention) and 6.84 ± 4.63 (control), respectively. There was a significant increase in MN counts for both groups (mean 12.5 and 13.8). Subgroup analysis for skin type, eye colour, and hair colour did not demonstrate a significant influence on MN counts. The DB-MIPS integrated classifier revealed no risky lesions while analysing their patterns. Intervention did not reduce the number of newly acquired MN. MN counts in pre-school children were approximately 5 times higher than expected from previous large studies in Germany. This is the first study in pre-school children using objective digital image analysis of pigmented lesions. No atypical lesions were observed. New approaches to UV protection in pre-school children are now required.

    Introduction Among all illness, Acute Respiratory Infections (ARI) account for 30-60% of paediatric outpatient attendance and 20-30% of hospital admissions. Aim To study the morbidity pattern of ARI among under-five-age group children and to assess the determinants. Materials and Methods A longitudinal cohort study was conducted for a one year period, comprising a cumulative sample of 400 children from 3 urban slums of Gulbarga city. History of nasal discharge, cough, fever, sore throat, breathing difficulty, any discharge from ear alone or in combination, was used in the recognition of an ARI episode. Respiratory rate >60/minute (<2 month infants), >50(2-11 months) and >40(1-5 years) in a child with cough, cold or fever singly or in combination was considered the criteria for recognition of pneumonia. Results Out of the 400 surveyed, ARI was detected among 109 children giving an incidence of 27.25%. Among these, Upper Respiratory Tract Infection (URTI) was found among 19.25% and Lower Respiratory Tract Infection (LRTI) among 8%. ARI was observed among 38.04% of infants, 37.84% of 2-3-year-old children, 36.87% of boys, 40.43% of children born to illiterate father’s, 35.77% of SES class IV & 40.79% of SES class V, and 41.89% of children with family history of respiratory illness. All these data were found to be statistically significant. High rates of ARI were also observed among 41.36% of children living in households with firewood fuel usage, 35.04% of children with pets in the household, 34.82% of children with delayed milestones, 53.85% of children with grade IV and 66.67% of children with grade V malnutrition. More episodes occurred during winter months of the year (Oct – Jan). During the follow-up phase of study done on a cohort of 112 children for a period of one year, an attack rate of 3.27 episodes/child/year was observed. Conclusion Community education programs should focus on addressing specific issues viz. identification of respiratory illness

    The present study investigated the relationship between blood pressure (BP), fat patterns and fitness parameters of Ellisras children aged 7-13 years. Furthermore, an assessment of body fat patterns was done to determine the subjects with the highest risk of overweight, hypertension and waist-to-hip ratio above the 90th percentile. Data were collected from 1,817 subjects (938 boys and 879 girls), aged 7-13 years, participating in the Ellisras Longitudinal Study. Anthropometric measurements were taken according to the standard procedure of the International Society for the Advancement of Kinanthropometry. The EUROFIT test items were used to test the physical fitness of 1,192 subjects (634 boys and 558 girls). Obesity was defined using the international recommended cutoff points for body mass index (BMI) in children. Hypertension was defined as the occurrence of BP levels greater or equal to the 95th percentile of height- and sex-adjusted reference levels. The prevalence of hypertension ranged from 1 to 11.4% and that of overweight 0.6-4.6%. Waist girth, BMI, triceps and subscapular skinfold showed significant (P<0.001-0.05) correlation with other fat pattern parameters (r ranging from -0.157 to 0.978) compared with significant correlations (P<0.001-0.05) with BP (r ranging from -0.071 to 0.164). Children with waist girth greater than the 90th percentile are more likely to have multiple risk factors than the children with a waist girth that is less than or equal to the 90th percentile. Longitudinal studies should verify whether changes in waist girth and skinfolds will indicate changes in cardiovascular risk factors during growth.

    Objectives To determine the accuracy of the caries risk assessment system and performance of clinicians in their attempts to predict caries for children during routine practice. Design Longitudinal study. Setting and participants Data on caries risk assessment conducted by clinicians during routine practice while providing care for children in the South Australian School Dental Service (SA SDS) were collected from electronic patient records. Baseline data on caries experience, clinicians’ ratings of caries risk status and child demographics were obtained for all SA SDS patients aged 5–15 years examined during 2002–2005. Outcome measure Children’s caries incidence rate, calculated using examination data after a follow-up period of 6–48 months from baseline, was used as the gold standard to compute the sensitivity (Se) and specificity (Sp) of clinicians’ baseline ratings of caries risk. Multivariate binomial regression models were used to evaluate effects of children's baseline characteristics on Se and Sp. Results A total of 133 clinicians rated caries risk status of 71 430 children during 2002–2005. The observed Se and Sp were 0.48 and 0.86, respectively (Se+Sp=1.34). Caries experience at baseline was the strongest factor influencing accuracy in multivariable regression model. Among children with no caries experience at baseline, overall accuracy (Se+Sp) was only 1.05, whereas it was 1.28 among children with at least one tooth surfaces with caries experience at baseline. Conclusions Clinicians’ accuracy in predicting caries risk during routine practice was similar to levels reported in research settings that simulated patient care. Accuracy was acceptable in children who had prior caries experience at the baseline examination, while it was poor among children with no caries experience. PMID:24477318

    Adult musicians show superior auditory discrimination skills when compared to non-musicians. The enhanced auditory skills of musicians are reflected in the augmented amplitudes of their auditory event-related potential (ERP) responses. In the current study, we investigated longitudinally the development of auditory discrimination skills in musically trained and nontrained individuals. To this end, we recorded the mismatch negativity (MMN) and P3a responses from children who play a musical instrument and age-matched children with no musical training at ages 7, 9, 11, and 13. Basic auditory processing was investigated by recording ERPs in the Multi-Feature Paradigm that included frequency, duration, intensity, location, and gap deviants. The detection of musically more relevant sound changes was examined in an oddball paradigm with major chords as standards and minor chords as deviants. The musically trained children showed larger increase in MMN and P3a amplitudes with age for the chord deviants than the control children. There was also a strong trend (p = .054) for larger increase in MMN amplitude in the musically trained children for the location deviant. As no group differences in response amplitudes were evident at the early stages of the training, our results suggest that the superior neural auditory discrimination in adult musicians is due to training and not pre-existing differences between musicians and non-musicians. © 2013 John Wiley & Sons Ltd.

    Sleep data were collected by maternal report in a prospective longitudinal follow up of cocaine-exposed and unexposed children. There were 139 participants: 23 with no prenatal drug exposure, 55 exposed to cocaine alone or in combination with other drugs, and 61 exposed to drugs other than cocaine. Characteristics differed between exposure groups including birth size, caretaker changes, maternal socioeconomic status, and postnatal drug use. Compared to those with no drug exposure, children with prenatal drug exposure other than cocaine experienced greater sleep problems (p = .026). Prenatal nicotine exposure was a unique predictor of sleep problems (p = .048). Early sleep problems predicted later sleep problems (all ps < .01). Together, these preliminary findings suggest possible neurotoxic sleep effects that persist over time. Larger studies, however, need to be conducted that better control for potential postnatal confounding factors.

    Although breastfeeding is associated with improving numerous health outcomes for the child, its role in reducing childhood obesity is contested. Despite this controversy, both the CDC and the US Department of Health and Human Services promote breastfeeding as one of the strategies for reducing childhood obesity. Rural Appalachia has one of the highest rates of childhood obesity and low rates of breastfeeding, compared to rest of the nation. The aim of this study was to examine the association between breastfeeding and childhood obesity at 11 years in the rural Appalachian state of West Virginia (WV). The study used linked data from two cross-sectional data sets to examine this relationship longitudinally in fifth-grade WV children. The main outcome variable was BMI adjusted percent (BMI%) and the main exposure was defined as occurrence of breastfeeding. Mean BMI% of children who were not breastfed was significantly higher, compared to children who were breastfed. The result of the multiple regression analysis showed that breastfeeding significantly predicted BMI% of children after controlling for maternal education, health insurance, family history of hypercholesterolemia and diabetes, child's asthma status, and birth weight of the infant. Our results are consistent with other studies that have shown a significant, but small, inverse association between breastfeeding and childhood obesity. Findings from this study suggest the need to improve breastfeeding rates in the rural Appalachian state of WV as one of the potential strategies to prevent obesity during childhood and adolescence.

    Elevated laughing and smiling is a key characteristic of the Angelman syndrome behavioral phenotype, with cross-sectional studies reporting changes with environment and age. This study compares levels of laughing and smiling in 12 participants across three experimental conditions [full social interaction (with eye contact), social interaction with no eye contact, proximity only] at two data points. No differences were noted in frequency of laughing and smiling over time in any condition. However, with age as a covariate, the frequency of laughing and smiling decreased over time in the full social interaction (with eye contact) condition only. As this is the first longitudinal study to explore these behaviors in Angelman syndrome, the results suggest a gene-environment-time interaction within the behavioral phenotype.

    This article describes a comprehensive assessment of treatment-related symptoms in children aged 0-18 years undergoing cancer treatment from the perspective of their parents. The aim was to describe which symptoms that, according to parents, cause most problems for children receiving cancer treatment and to explore whether there is a relationship between parents' ratings of their children's symptoms and their own post-traumatic stress at one week (T1), two months (T2), and four months (T3) after a child's cancer diagnosis. In total, 214 parents (107 mothers and 107 fathers) of 115 children answered a modified version of the Memorial Symptom Assessment Scale 10-18 and the PTSD Checklist Civilian Version over the telephone at T1-T3. According to parents, the following symptom areas cause the most problems for children undergoing cancer treatment: emotional distress, fatigue, nutrition, and pain. Pain is the most problematic area. The prevalence of most symptoms and the symptom burden decreases over time. Parents' ratings of their children's symptom burden and their own emotional distress, and mothers' and fathers' ratings of their child's symptom burden, are associated. Parents of adolescents report a greater symptom burden for their child than the parents of the youngest children. The opinions of both the patient and the parent are important in pediatrics. The results of this study can be used to guide health care professionals within pediatric oncology in their discussions of cancer treatment's adverse effects with patients and families. Not only the expectations and potential interventions but also the sources of worry should be discussed. Copyright © 2010 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc.

    2007-06-01

    Based upon a longitudinal anthropometric study with integrated picture documentation, the head proportion and head shape of two to seven years old children will be analysed. The study was initiated in April 2002 in the administrative districts of Potsdam and Potsdam-Mittelmark (Germany). 351 boys and girls have been measured and photographed. The children shall be examined up to four years until September 2006 with a half year investigation distance. Twenty-three anthropometric dimensions have been measured including six dimensions of the head. These dimensions of the head are the head length, head breadth, auricular height, interpupillary distance, facial height and lower face height. Furthermore, digital pictures have been taken of each child. So the head of each child can be examined in a frontal view (Norma frontalis) and in a lateral view (Norma lateralis) and will be analysed relating to changing proportions of the head. The results demonstrated and discussed here are based on a longitudinal succession of photos and point out a method to make individual patterns of the changing head proportions and head shape visual on pictures.

    Introduction Like sleeping and eating habits, the study habits adopted by children when they are at home are important contributors to lifestyle and they affect cognitive ability. It has recently been reported that sleeping and eating habits change the brain structure of children. However, no research on the effect of study habits at home on the brain structure of children has been conducted thus far. We investigated the effects of study habits at home on the brain structures of healthy children by examining correlations between study time at home and changes in brain structure over the course of 3 years. Methods We used the brain magnetic resonance images of 229 healthy children aged 5.6–18.4 years and computed the changes (time 2–time 1) in regional gray matter and white matter volume (rWMV) using voxel-based morphometry. Whole-brain multiple regression analysis revealed a significant positive correlation between study time at home and changes in rWMV in the right superior frontal gyrus (SFG). Behaviorally, we found a significant positive correlation between study time at home and change in the verbal comprehension index (VCI), one of the subscales of the Wechsler Intelligence Scale for Children–third edition (WISC–III). Results and Conclusions Given that the SFG is involved in memory control and that the VCI measures abilities related to vocabulary, our results indicate that greater SFG involvement in the memorization component of longer study times may result in greater increases in the number of axons and more axon branching and myelination, causing plastic changes in the neural network involved in memory processes.

    Brattström, V; Odenrick, L; Kvam, E

    1989-05-01

    Playing wind instruments requires increased ventilation and increased orofacial muscle activity. The aim of the present investigation was to study the longitudinal effects on the dentofacial morphology of increased ventilation and orofacial muscle activity associated with playing wind instruments. Lateral cephalograms and dental casts obtained from wind instrument players at the ages of 6, 9, 12, and 15 years were studied and compared to control groups. In addition information was obtained as to how many hours per day they practised their instruments. Significant differences between the musicians and controls were found. The musicians had a decreased anterior facial height and wider dental arches. The findings are interpreted as being due to increased orofacial muscle activity and increased intra-oral pressure resulting from wind instrument playing.

    There is growing interest in the association between anthropometric measurements and dental caries in childhood over time (life-course studies). The aim of this review was to identify and systematically review the evidence of the association between anthropometric measurements and dental caries in childhood over time. PubMed, Institute for Scientific Information (ISI) Web of Knowledge, the Cochrane Library, and 6 other databases were searched to identify effective articles. A systematic approach involving critical appraisal was conducted to examine the relation between anthropometric measurements and dental caries in preschool- and school-aged populations from longitudinal studies. An initial search identified 1338 studies, with 59 potentially effective studies (κ = 0.82) and 17 effective studies (κ = 0.88). The quality of reporting among the studies ranged from 19.5 to 30.0 according to the Strengthening the Reporting of Observational studies in Epidemiology (STROBE) criteria. Among the effective studies, 2 studies in which caries was used to predict anthropometric measurements consistently found an inverse association and 15 studies in which anthropometric measurements were used to predict caries were inconsistent, with results appearing to be influenced by nonuniformity of assessments, setting, and procedure of measurements; age and ethnicity of participants; and confounders of dental caries. In conclusion, among >1000 studies identified, 17 informed this systematic review. The quality of reporting of these studies varied considerably. Evidence of the association between anthropometric measurements and dental caries is conflicting and remains inconclusive. © 2015 American Society for Nutrition.

    Children born small for gestational age (SGA) have an increased risk of cardiovascular disease (CVD) and associated risk factors in later life; however, little is known about their dietary intakes. The objective of this study was to assess dietary intakes in SGA and appropriate for gestational age (AGA) at 3.5, 7, and 11 years. The Auckland Birthweight Collaborative Study is a longitudinal case-control study of children born at term (n = 871). Children were assessed at 3.5 (n = 550), 7 (n = 591), and 11 (n = 620) years of age. Diet was assessed using a 24-hr record-assisted recall. Reported dietary intakes were analyzed and compared with the Australian and New Zealand Nutrient Reference Values. Compared with AGA, median energy intakes were significantly lower in SGA at 3.5 years (4.2 MJ [IQR, 3.0 to 5.8] vs. 5.4 MJ [IQR, 3.9 to 6.5]; p < .0001) but not at 7 and 11 years. Inadequate dietary intakes of micronutrients were more prevalent among SGA at 3.5 years and 11 years of age. A large proportion of SGA and AGA children consumed more than the recommended amounts of saturated fats, sugars, and sodium. There was no association of dietary intake and socio-demographic factors. This study reveals that dietary intake in 3.5-year-old children born SGA is lower in energy and a variety of micronutrients compared with dietary intake in AGA. These intakes may however be appropriate given their BMI z-scores. High intakes of sodium, saturated fat, and sugars are a concern for all children in this cohort. © 2016 John Wiley & Sons Ltd.

      In this study, we explored the integrity of the inferior longitudinal fasciculus (ILF) by means of diffusion tensor imaging tractography in children with visual perceptual impairment, and more specifically, object recognition deficits, compared with typically developing children.   Eleven individuals (nine males, two females; mean age 7 y 8 mo; range 3 y 5 mo-13 y) were assessed with the L94 visual perceptual battery after assessment of performance age. In all participants, an ophthalmological evaluation was carried out. Diffusion tensor imaging tractography of the ILF was performed. The mean fractional anisotropy was determined for every child and compared with data for 11 age- and sex-matched typically developing children.   The mean fractional anisotropy value in the left ILF was consistently lower in the study participants than in the comparison group. The five children with L94 impairment showed a significantly lower ILF fractional anisotropy on the left as well as on the right side. Furthermore, the decrease in ILF fractional anisotropy was correlated with the number of impaired subtests. The results suggest an association between ILF integrity loss and object recognition deficits. Moreover, the severity of clinical impairment is reflected in the degree of ILF integrity loss. Therefore, the ILF plays a potential role in object recognition. © The Authors. Developmental Medicine & Child Neurology © 2011 Mac Keith Press.

    To date, there has been no study done investigating the relationship between the components of height and blood pressure (BP) in rural South African children. Therefore, the aim of this study was to investigate the relationship between height, sitting height (SH), leg length (LL), and SH-to-height ratio (SH/H) with BP in Ellisras rural children. All children underwent anthropometric and BP measurements using standard procedure. Linear regression was used to assess the relationship between height, SH, LL, SH/H, and BP. The regression showed a positive significant (p < 0.001) association between systolic BP (SBP) with height and SH (β ranged from 0.127 to 0.134 and 95% CI ranged from 0.082 to 0.415). Diastolic BP (DBP) also showed a positive significant (p < 0.001) association with height and SH (β ranged from 0.080 to 0.088 and 95% CI ranged from 0.042 to 0.259). After having been adjusted for age, gender, body mass index, and waist circumference, DBP showed a positive significant (p < 0.05) association with height. There was a positive significant association between DBP and SBP together with the components of height amongst Ellisras rural children. PMID:27618907

    To investigate whether second-to-fourth digit ratio (2D:4D), a measure commonly used as a proxy for fetal testosterone exposure, is associated with autism spectrum disorders (ASDs), as predicted by the extreme male brain theory of autism. A birth cohort study. The Avon Longitudinal Study of Parents and Children (ALSPAC). 6015 ALSPAC children with data on digit ratio, at least 1 outcome measure and information on potential confounding variables (parental occupational class, maternal education and age at digit ratio measurement). Digit ratio was measured by the photocopy and calliper method. ASD diagnosis (cases were identified previously by record linkage or maternal report) and 4 measures that combine optimally within ALSPAC to predict ASD: the Children's Communication Checklist (coherence subscale), the Social and Communication Disorders Checklist, a repetitive behaviour measure, and the Emotionality, Activity and Sociability scale (sociability subscale). These measures were dichotomised, with approximately 10% defined as the 'risk' group. Using logistic regression, we examined the association of 2D:4D with ASDs and 4 dichotomised ASD traits. Covariates were occupational class, maternal education and age at 2D:4D measurement. 2D:4D was not associated with ASDs in males (adjusted OR per 1 SD increase in mean 2D:4D, 0.88 (95% CI 0.65 to 1.21), p=0.435) or females (adjusted OR=1.36 (95% CI 0.81 to 2.28), p=0.245). Similar results were observed after adjustment for IQ. There was 1 weak association between reduced coherence and increased left 2D:4D in males, in the opposite direction to that predicted by the extreme male brain theory (adjusted OR=1.15 (95% CI 1.02 to 1.29), p=0.023). Given multiple comparisons, this is consistent with chance. In this population-based study, there was no strong evidence of an association between 2D:4D and ASD diagnosis or traits, although the CIs were wide. These results are not consistent with the extreme male brain theory. Published

    Childhood has been targeted as an especially important period for self-esteem formation. The aim of this study is to examine the change and associated factors of self-esteem among children in rural China. A two-year longitudinal study was conducted with a general elementary and secondary school population in Anhui Province, China including 816 children aged between 7 and 16 years. Generalized estimating equation (GEE) was used to examine relationships between low self-esteem and socio-demographic, family environment, and psychosocial factors. On average, self-esteem level among children was increased across three assessments. Multivariable analysis (GEE) showed that low self-esteem in children was clearly associated with male gender (OR = 1.45, 95%CI = 1.12-1.89), moderate and severe family dysfunction (OR = 1.88, 95%CI = 1.40-2.51; OR = 1.88, 95%CI = 1.25-2.83, respectively), quality of life (OR = .97, 95%CI = .96-.98), depression (OR = 1.89, 95%CI = 1.32-2.70), anxiety (OR = 2.05, 95%CI = 1.51-2.77), positive coping styles (OR = .91, 95%CI = .89-.94), and negative coping styles (OR = 1.05, 95%CI = 1.03-1.07). Self-esteem is a dynamic rather than a static construct during childhood. Low self-esteem among children was associated with a number of socio-demographic, family environment, and psychosocial factors. Further studies exploring the pathways and mechanisms by which the effect of these factors impact on self-esteem among children are warranted.

    Oral language is the foundation of literacy. Naturally, policies and practices to promote children's literacy begin in early childhood and have a strong focus on developing children's oral language, especially for children with known risk factors for low language ability. The underlying assumption is that children's progress along the oral to literate continuum is stable and predictable, such that low language ability foretells low literacy ability. This study investigated patterns and predictors of children's oral language and literacy abilities at 4, 6, 8 and 10 years. The study sample comprised 2,316 to 2,792 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Six developmental patterns were observed, a stable middle-high pattern, a stable low pattern, an improving pattern, a declining pattern, a fluctuating low pattern, and a fluctuating middle-high pattern. Most children (69%) fit a stable middle-high pattern. By contrast, less than 1% of children fit a stable low pattern. These results challenged the view that children's progress along the oral to literate continuum is stable and predictable. Multivariate logistic regression was used to investigate risks for low literacy ability at 10 years and sensitivity-specificity analysis was used to examine the predictive utility of the multivariate model. Predictors were modelled as risk variables with the lowest level of risk as the reference category. In the multivariate model, substantial risks for low literacy ability at 10 years, in order of descending magnitude, were: low school readiness, Aboriginal and/or Torres Strait Islander status and low language ability at 8 years. Moderate risks were high temperamental reactivity, low language ability at 4 years, and low language ability at 6 years. The following risk factors were not statistically significant in the multivariate model: Low maternal consistency, low family income, health care card, child not read to at home

    Objective To examine if maltreatment predicted increased risk of hospital-based treatment prior to age 18 years for asthma, cardio-respiratory, and non-sexually transmitted infectious disease in a sample of low-income children. Methods This study used administrative data from multiple systems to follow children for 12–18 years (N = 6,282). Cox regression was used to explore the risk of first hospital treatment by disease category. Negative binomial regression was used to explore the relationship between recurrent maltreatment and total hospital care episodes. Results Controlling for individual, family, and community factors, children with maltreatment reports had a 74–100% higher risk of hospital treatment. Recurrent reports predicted a higher count of hospital care episodes. Conclusions The negative health impact of maltreatment prior to adulthood supports the need for early prevention and intervention to prevent initial and recurrent child abuse and improve capacity to meet healthcare needs of maltreated children.

    Urban upbringing is associated with a 2-fold adulthood psychosis risk, and this association replicates for childhood psychotic symptoms. No study has investigated whether specific features of urban neighborhoods increase children's risk for psychotic symptoms, despite these early psychotic phenomena elevating risk for schizophrenia and other psychiatric disorders in adulthood. Analyses were conducted on over 2000 children from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative cohort of UK-born twins. Neighborhood-level characteristics were assessed for each family via: a geodemographic discriminator indexing neighborhood-level deprivation, postal surveys of over 5000 residents living alongside the children, and in-home interviews with the children's mothers. Children were interviewed about psychotic symptoms at age 12. Analyses were adjusted for important family-level confounders including socioeconomic status (SES), psychiatric history, and maternal psychosis. Urban residency at age-5 (OR = 1.80, 95% CI = 1.16-2.77) and age-12 (OR = 1.76, 95% CI = 1.15-2.69) were both significantly associated with childhood psychotic symptoms, but not with age-12 anxiety, depression, or antisocial behavior. The association was not attributable to family SES, family psychiatric history, or maternal psychosis, each implicated in childhood mental health. Low social cohesion, together with crime victimization in the neighborhood explained nearly a quarter of the association between urbanicity and childhood psychotic symptoms after considering family-level confounders. Low social cohesion and crime victimization in the neighborhood partly explain why children in cities have an elevated risk of developing psychotic symptoms. Greater understanding of the mechanisms leading from neighborhood-level exposures to psychotic symptoms could help target interventions for emerging childhood psychotic symptoms. © The Author 2016.

    2014-01-01

    Background Cross-sectional studies detected associations between physical fitness, living area, and sports participation in children. Yet, their scientific value is limited because the identification of cause-and-effect relationships is not possible. In a longitudinal approach, we examined the effects of living area and sports club participation on physical fitness development in primary school children from classes 3 to 6. Methods One-hundred and seventy-two children (age: 9–12 years; sex: 69 girls, 103 boys) were tested for their physical fitness (i.e., endurance [9-min run], speed [50-m sprint], lower- [triple hop] and upper-extremity muscle strength [1-kg ball push], flexibility [stand-and-reach], and coordination [star coordination run]). Living area (i.e., urban or rural) and sports club participation were assessed using parent questionnaire. Results Over the 4 year study period, urban compared to rural children showed significantly better performance development for upper- (p = 0.009, ES = 0.16) and lower-extremity strength (p < 0.001, ES = 0.22). Further, significantly better performance development were found for endurance (p = 0.08, ES = 0.19) and lower-extremity strength (p = 0.024, ES = 0.23) for children continuously participating in sports clubs compared to their non-participating peers. Conclusions Our findings suggest that sport club programs with appealing arrangements appear to represent a good means to promote physical fitness in children living in rural areas. PMID:24886425

    A recent meta-analytic review of cross-sectional studies examining correlations between peer victimization and indices of internalizing problems indicates that victims of bullying are highly distressed. However, the reliance on cross-sectional studies precludes interpretation of the direction of effects. The present study was designed to investigate if internalizing problems are antecedents of victimization, consequences of victimization, or both. This paper provides a meta-analysis of 18 longitudinal studies examining prospective linkages between peer victimization and internalizing problems (n=13,978). Two prospective paths were examined: the extent to which peer victimization at baseline predicts changes in internalizing problems, as well as the extent to which internalizing problems at baseline predict changes in peer victimization. Results revealed significant associations between peer victimization and subsequent changes in internalizing problems, as well as significant associations between internalizing problems and subsequent changes in peer victimization. Several moderator effects were observed. Internalizing problems function as both antecedents and consequences of peer victimization. These reciprocal influences suggest a vicious cycle that contributes to the high stability of peer victimization. This study should further encourage steps to reduce bullying at schools.

    Informal music activities such as singing may lead to augmented auditory perception and attention. In order to study the accuracy and development of music-related sound change detection in children with cochlear implants (CIs) and normal hearing (NH) aged 4-13 years, we recorded their auditory event-related potentials twice (at T1 and T2, 14-17 months apart). We compared their MMN (preattentive discrimination) and P3a (attention toward salient sounds) to changes in piano tone pitch, timbre, duration, and gaps. Of particular interest was to determine whether singing can facilitate auditory perception and attention of CI children. It was found that, compared to the NH group, the CI group had smaller and later timbre P3a and later pitch P3a, implying degraded discrimination and attention shift. Duration MMN became larger from T1 to T2 only in the NH group. The development of response patterns for duration and gap changes were not similar in the CI and NH groups. Importantly, CI singers had enhanced or rapidly developing P3a or P3a-like responses over all change types. In contrast, CI non-singers had rapidly enlarging pitch MMN without enlargement of P3a, and their timbre P3a became smaller and later over time. These novel results show interplay between MMN, P3a, brain development, cochlear implantation, and singing. They imply an augmented development of neural networks for attention and more accurate neural discrimination associated with singing. In future studies, differential development of P3a between CI and NH children should be taken into account in comparisons of these groups. Moreover, further studies are needed to assess whether singing enhances auditory perception and attention of children with CIs.

    The purpose of this study was to examine developmental change associated with catching by children in Grades Kindergarten through 8. Children's performance was tested on the Catching Subtest of the Ohio State University Scale of Intra Gross Motor Assessment (OSU-SIGMA). More precisely, four cohorts of boys and girls in Grades K-8 (N = 340) from 1992 to 2000: in 1992 Grades K-8, in 1994 Grades 2-8, in 1996 Grades 4-8, and in 1998 Grades 6-8. In 2000, the original Kindergarten cohort was tested again. Data, analyzed by hierarchical nonlinear modeling, yielded significant differences in mean initial status (intercept) of all three cohorts, in mean growth rate (slope) for the K-8 cohort only, in initial status of the K-8 cohort, and for participants in baseball and softball.

    This twin study examined the bidirectional relationship between maternal parenting behaviors and children's peer problems that were not confounded by genetic and family environmental factors. Mothers of 259 monozygotic twin pairs reported parenting behaviors and peer problems when twins were 42 and 48 months. Path analyses on monozygotic twin difference scores revealed that authoritative parenting (the presence of consistent discipline and lack of harsh parenting) and peer problems simultaneously influenced each other. Authoritative parenting reduced peer problems, and peer problems increased authoritative parenting. Neither consistent discipline nor harsh parenting alone was associated with peer problems. These results suggest that maternal authoritative parenting works protectively in regard to children's peer problems, and peer problems can evoke such effective parenting. © 2012 Blackwell Publishing Ltd.

    How does the cognitive development of children conceived after ART (IVF and ICSI) - measured as cognitive skills at age 3, 5, 7 and 11 years - differ over time from those born after natural conception (NC)? Improved measures of cognitive development up to age 5 years were recorded in children conceived with ART compared to NC, which attenuates by 11 years, with ART children still scoring slightly better than NC children. Results on the cognitive outcomes of children conceived after ART have been highly contradictory. Some have shown that ART children have an impaired behavioural, socio-emotional and cognitive development and higher risk of mental disorders. Others have reported no increased risk or difference. Cognitive development has not been previously examined using latent growth curve models from ages 3 to 11 years, also including appropriate attention to confounding parental characteristics. Longitudinal data for the first five waves (2000-2012) of the UK Millennium Cohort Study were used, which is a two-stage sample of all infants born in 2000-2001 and resident in the UK at 9 months of age, drawn from the Department of Social Security Child Benefit Registers. A final sample of N = 15 218 children (125 IVF and 61 ICSI), from 14 816 families was used. Information was available for all waves for 8298 children. Four additional follow-up surveys were conducted in 2003, 2005, 2007 and 2012. Our sample includes children born within a union (married or cohabiting parents) and where information on cognitive scores was available for at least two measurement points. Cognitive development was assessed with the British Ability Scales. At age 3 and 5 years (wave 2 and 3), children completed the naming vocabulary component, which measures expressive verbal ability. At age 7 years (wave 4), verbal cognitive abilities were assessed through the word reading test, and at age 11 years (wave 5) through a verbal similarity test. Two-tailed Student's t-tests examined differences

    Background Outcomes of health and rehabilitation services for children and youth with disabilities increasingly include assessments of health-related quality of life (HRQoL). The purpose of this research was to 1) describe overall patterns of HRQoL, 2) examine changes in parent’s perceptions of child’s HRQoL across 18 months and 3) explore factors that predict these changes. Methods Participants in this study included 427 parents of children (229 boys and 198 girls) with a physically-based disability between the ages of 6 to 14 years. The Child Health Questionnaire (CHQ) was administered three times, at nine month intervals. Comparisons to the CHQ normative data were analyzed at Time 1 using t-tests, and change over time was examined using linear mixed-effects models. Possible predictors were modeled: 1) child’s factors measured by the Activities Scale for Kids, Strengths and Difficulties Questionnaire, and general health measured by SF-36, 2) family characteristics measured by the Impact on Family Scale and 3) environmental barriers measured by the Craig Hospital Inventory of Environmental Factors. Results CHQ scores of the study’s participants demonstrated significantly lower summary scores from the normative sample for both CHQ Physical and Psychosocial summary scores. On average, children did not change significantly over time for physical summary scores. There was an average increase in psychosocial health that was statistically significant, but small. However, there was evidence of heterogeneity among children. Environmental barriers, behavioral difficulties, family functioning/impact, general health and child physical functioning had negative and significant associations with physical QoL at baseline. Change in physical QoL scores over time was dependent on children’s behavioral difficulties, family functioning and environmental barriers. Environmental barriers, behavioral difficulties, family functioning/impact and general health had significant

    Physical activity is associated with an array of physical and mental health benefits among children and adolescents. The development of self-worth/self-esteem has been proposed as a mechanism to explain the mental health benefits derived from physical activity. Despite several studies that have analyzed the association between physical activity and self-worth, the results have been inconsistent. It is also uncertain how related physical health measures, such as sedentary behavior, body composition, and fitness, influence the relationship between physical activity and self-worth over time. In the present study, we 1) analyzed if the association between physical activity and self-worth remained constant over time and whether this relationship varied by sex and 2) investigated if changes in body composition and fitness level mediated the relationship between physical activity and self-worth. Data from the Physical Health Activity Study Team were used for this analysis. The Physical Health Activity Study Team is a prospective cohort study that included 2278 children at baseline (ages 9-10 yr) and included eight follow-up contacts for a 4-yr study period. Linear mixed-effects models were used to estimate global self-worth (GSW) over follow-up. Increased physical activity was associated with greater GSW across all waves of data collection, and this relationship did not vary significantly over time or between sexes. Aerobic fitness was positively associated with GSW, whereas body mass index (BMI) was inversely related to GSW. Both aerobic fitness and BMI appeared to mediate the association between physical activity and GSW. Sedentary behavior was not significantly associated with GSW. Physical activity is associated with greater GSW, and this relationship appears to be mediated by BMI and aerobic fitness. These findings reinforce the importance of physical behaviors and physical characteristics in shaping GSW in children.

    Objective To identify characteristics associated with inability to progress to open-set speech recognition in children who are 5 years post cochlear implantation. Study Design Prospective, longitudinal and multidimensional assessment of auditory development over 5 years. Setting Six tertiary cochlear implant (CI) referral centers in the US. Patients Children with severe-to-profound hearing loss who underwent implantation before age 5 years enrolled in the Childhood Development after Cochlear Implant (CDaCI) study, categorized by level of speech recognition ability. Intervention(s) Cochlear implantation prior to 5 years of age and annual assessment of emergent speech recognition skills. Main outcome measure(s) Progression to open-set speech recognition by 5 years after implantation. Results Less functional hearing prior to implantation, older age at onset of amplification, lower maternal sensitivity to communication needs, minority status, and complicated perinatal history were associated with inability to obtain open set speech recognition by 5 years. Conclusions Characteristics of a subpopulation of children with CIs that were associated with an inability to achieve open-set speech recognition after 5 years of CI experience were investigated. These data distinguish pediatric CI recipients at risk for poor auditory development and highlight areas for future interventions to enhance support of early implantation. PMID:25700015

By using the Early Childhood Longitudinal Study-Kindergarten Cohort 1998-1999 (N = 8,250), we modeled BMI and z score change by ADHD and stimulant start time, examined the odds of unhealthy diet and physical activity predicted by ADHD and stimulant use, and performed mediation analysis assessing indirect effects of health behaviors. Early stimulant use predicted short-term BMI reductions, but any stimulant use predicted increased BMI growth between fifth grade (mean age = 11.2 years) and eighth grade (mean age = 14.3 years). Children with ADHD had higher odds of poor diet regardless of medication. Health behaviors were not associated with BMI change after controlling for medication use. Stimulant use predicted higher BMI trajectory between fifth and eighth grade but did not affect dietary or physical activity patterns. Future research should explore potential mechanisms by which early and long-term stimulant use may affect metabolism, while clinicians should initiate nutrition counseling with families of children with ADHD, regardless of medication prescription, at or shortly after diagnosis. © 2017 The Obesity Society.

    Using a unique longitudinal data of British youths we estimate how adolescents' overall happiness is related to parents' exposure to unemployment. Our within-child estimates suggest that parental job loss when the child was relatively young has a positive influence on children's overall happiness. However, this positive association became either strongly negative or statistically insignificant as the child grew older. The estimated effects of parental job loss on children's happiness also appear to be unrelated to its effect on family income, parent–child interaction, and children's school experience. Together these findings offer new psychological evidence of unemployment effects on children's livelihood. PMID:24932068

    Because infants and toddlers are particularly susceptible to parents' socialization efforts, the purpose of this 2-year longitudinal study (N=4271 infants) was to forecast toddlers' competence and problems (adaptational outcomes, age M=30 months) from parenting experiences when they were infants (age M=9 months). Using structural equation modeling and data from a nationally representative sample, parenting during infancy was important to toddlers' adaptational outcomes, with parenting warmth most strongly connected to toddler competence and parenting hostility most strongly connected to toddler problems. Additionally, toddlers' outcomes were associated with their parents' mental health symptoms, life difficulty, coping and self-efficacy when measured 2 years earlier (parent context), and parenting warmth and hostility mediated some of these associations. These pathways indicated that the infant parenting context had some spill over effect on toddlers via parental warmth and hostility. However, mediational paths were not as common as expected, suggesting that the parent context had more direct than indirect effects on toddlers. Conclusions were similar even after accounting for infant temperament, family demographic characteristics and infant birthweight, with substantial reductions in effects only found for associations of parenting self-efficacy with toddlers' outcomes.

    The neurohabilitation treatment has been shown to be a successful method for decreasing the sequelae of perinatal brain damage (PBD) in Hungarian population. The goal of this pilot trial was to introduce this procedure by describing the results of its application in infants with PBD as demonstrated by clinical, developmental and MRI studies. As this procedure has proved to be useful, according the declaration of Helsinki, no control clinical trial was permitted. Infants younger than 2 months of corrected age (CA) with prenatal and/or perinatal risk factors for brain damage. Two groups were considered. One group was treated using the "neurohabilitation" method (n=20), and the other was not treated (n=13) because treatment was voluntarily discontinued after the initial evaluation. Evaluations were carried out prior to 2 months of CA and at 6-8 years of age. All children showed abnormal clinical and MRI characteristics in the first study. The treated group had a higher percentage (90%) of children with normal outcome than did the non-treated group (38%; OR=2.37, CI 95%=1.2-4.7; p<0.005). In this latter group, only one out of five (20%) children born at or before 34 weeks of gestational age had a normal outcome. In contrast, eight out of nine treated preterm infants had normal outcomes (8/9=89%, OR=4.45, CI 95%=0.7-26; p=0.017). This pilot trial confirms previous studies suggesting that Neurohabilitation decreases the neurological and cognitive sequelae of preterm and at-term infants with PBD.

    Maternal prenatal anxiety and stress (PNS) have been positively associated to physical health prob lems in offspring in the first year of life. Whether these associations are transient, persistent, or even progressive over time, is as yet unknown. The goal of this study is to investigate associations between late pregnancy PNS and child health from 18 months to age 6. Mothers were recruited in late pregnancy, and had uncomplicated, singleton pregnancies without physical health problems. Around week 37 of pregnancy, mothers reported on their PNS by means of questionnaires, and provided saliva for determination of circadian cortisol concentrations. Children's illnesses in the preceding year were assessed using maternal reports at 30, 48, 60, and 72 months. Antibiotic use was obtained from medical records between one and six years. Multilevel models (N¼174) showed a positive relation between maternal prenatal general and pregnancy-specific anxiety during late pregnancy and offspring respiratory illnesses and symptoms. Interaction effects with time indicated that more PNS was related to more respiratory illnesses until toddlerhood, but not later in life. Furthermore, maternal prenatal cortisol concentrations were related to child digestive illnesses. A steeper maternal cortisol decline over the day was related to more child digestive illnesses, until around three years of age. Finally, children of mothers who suffered more from daily hassles during pregnancy received more antibiotics between one and six years of age. PNS was not related to general and skin illnesses. Summarizing, this study showed that late pregnancy anxiety and cortisol was associated with children's respiratory and digestive illnesses till the age of 3.0-3.5 years. Additionally, more daily hassles were related to more prescribed antibiotics between one and six years. These findings point in the direction of possible effects of PNS persisting beyond the first year of life and into toddlerhood, but

    The development of the ability to adapt one's motor performance to the constraints of a movement task was examined in a longitudinal study involving 7 to-9-year-old children who were asked to perform a preparatory handwriting task. The capacity for sensorimotor synchronization was captured by the standard deviation of the relative phase between pacing signals and writing movements and the capacity to adjust wrist-finger coordination while performing repetitive movements was analyzed by autocorrelations of the vertical pen-tip displacements. While the capacity for synchronization improved with age, the autocorrelations were positive at short time lags only and hardly changed with age. A measure of "the long-term memory" of time series (Hurst exponent) confirmed that the findings were systematic rather than noise. Collectively, the results indicate that flexible movement strategies emerge early on in the first 3 years of formal handwriting education. Implications for educational and clinical practice are considered.

    Both general and math-specific anxiety are related to proficiency in mathematics. However, it is not clear when math anxiety arises in young children, nor how it relates to early math performance. This study therefore investigated the early association between math anxiety and math performance in Grades 2 and 3, by accounting for general anxiety and by further inspecting the prevalent directionality of the anxiety-performance link. Results revealed that this link was significant in Grade 3, with a prevalent direction from math anxiety to performance, rather than the reverse. Longitudinal analyses also showed an indirect effect of math anxiety in Grade 2 on subsequent math performance in Grade 3. Overall, these findings highlight the importance of monitoring anxiety from the early stages of schooling in order to promote proficient academic performance.

    2014-01-01

    Brief review is provided of recent research on the impact of early visual language exposure on a variety of developmental outcomes, including literacy, cognition, and social adjustment. This body of work points to the great importance of giving young deaf children early exposure to a visual language as a critical precursor to the acquisition of literacy. Four analyses of data from the Visual Language and Visual Learning (VL2) Early Education Longitudinal Study are summarized. Each confirms findings from previously published laboratory findings and points to the positive effects of early sign language on, respectively, letter knowledge, social adaptability, sustained visual attention, and cognitive-behavioral milestones necessary for academic success. The article concludes with a consideration of the qualitative similarity hypothesis and a finding that the hypothesis is valid, but only if it can be presented as being modality independent.

    Utilizing a cohort sequential design and multilevel modeling on a sample of 113 mothers, the effects of four coping strategies (engagement, disengagement, distraction, and cognitive reframing) on multiple measures of maternal adjustment were assessed over a 7 years period when children with autism spectrum disorders in the study were approximately 7-14 years old. Findings indicated increased use of disengagement and distraction to be related to increased maternal maladjustment over time, while increased use of cognitive reframing was linked to improved maternal outcomes (findings regarding engagement's effects on adjustment measures were mixed). In addition, results indicated that use of different coping strategies at times moderated the effects of child behavior on maternal adjustment. Study findings are discussed in light of prior research and study limitations and clinical implications are highlighted.

  1. The Children’s Attention Project: a community-based longitudinal study of children with ADHD and non-ADHD controls

    PubMed Central

    2013-01-01

    Background Attention-Deficit/Hyperactivity Disorder (ADHD) affects approximately 5% of children worldwide and results in significant impairments in daily functioning. Few community-ascertained samples of children with ADHD have been studied prospectively to identify factors associated with differential outcomes. The Children’s Attention Project is the first such study in Australia, examining the mental health, social, academic and quality of life outcomes for children with diagnostically-confirmed ADHD compared to non-ADHD controls. The study aims to map the course of ADHD symptoms over time and to identify risk and protective factors associated with differential outcomes. Methods/design The sample for this prospective longitudinal study is being recruited across 43 socio-economically diverse primary schools across Melbourne, Australia. All children in Grade 1, the second year of formal schooling (6–8 years), are screened for ADHD symptoms using independent parent and teacher reports on the Conners’ 3 ADHD index (~N = 5260). Children screening positive for ADHD by both parent and teacher report, and a matched sample (gender, school) screening negative, are invited to participate in the longitudinal study. At baseline this involves parent completion of the NIMH Diagnostic Interview Schedule for Children IV (DISC-IV) to confirm likely ADHD diagnostic status and identify other mental health difficulties, direct child assessments (cognitive, academic, language and executive functioning; height and weight) and questionnaires for parents and teachers assessing outcomes, as well as a broad range of risk and protective factors (child, parent/family, teacher/school, and socio-economic factors). Families will be initially followed up for 3 years. Discussion This study is the first Australian longitudinal study of children with ADHD and one of the first community-based longitudinal studies of diagnostically confirmed children with ADHD.

    Objective To present data on the parentally-reported use of all types of medicinal products in children from 0 to 7.5 years, in a large cohort in south-west England. Methods Participants in the population-based Avon Longitudinal Study of Parents and Children (ALSPAC) have been sent self-completion postal questionnaires since they were enrolled during pregnancy. The use of medicinal products has been obtained from questionnaires sent out when the study children were 4 weeks, 54, 78 and 91 months old. Results The data included prescription, over-the-counter and complementary and alternative medicines. Around three-quarters of study children were exposed to some form of medicinal product before 8 weeks of age. Dermatological preparations were the most commonly used products in young babies. Activated dimeticone, for treatment of colic and flatulence, was given to 16% of babies and gripe water was used by 13%. Other commonly reported products included oral and topical antifungals and ophthalmic antibiotics. Several OTC products, not licensed for use in this age group, were reported. At each of the older ages surveyed, over 95% of children had used some form of medicinal product within the previous 12–18 months. Use of several product categories was higher at 54 months than at 78 or 91 months, such as topical steroids, analgesics (mostly paracetamol) and systemic antibiotics (mainly amoxicillin). Conversely, use of other categories, such as asthma medication, throat preparations (sprays and lozenges) and anti-inflammatory products, increased with increasing age. Conclusion Parentally-reported use of medicinal products in the ALSPAC study children appears to be consistent with data from other sources. The use of medicinal products by young children is high and does not always conform to the product labelling. PMID:17200835

    The present article examined the development of relational aggression in middle childhood and the effects of observed teacher behavior on this development. Relying on social learning theory, we expected that teacher praise would slow down the increase of relational aggression, whereas teacher reprimands would promote the increase of relational aggression. A sample of 570 children (49% boys, Mage=7years and 5months, >95% Belgian) was followed from second to fourth grade. Teacher praise and reprimands were observed at the beginning of second grade. Child relational aggression was assessed using teacher and peer reports, collected at five points in time: at the beginning and end of the second grade, at the beginning and end of the third grade, and at the end of the fourth grade. Multilevel modeling showed that relational aggression generally increased from second to fourth grade. Moreover, when teachers displayed more praise, students' relational aggression increased at a slower rate; when teachers displayed more reprimands, students' relational aggression increased at a faster rate. Overall, the results stress the importance of supporting teachers to reduce reprimands and increase praise when interacting with children. Copyright © 2017 Society for the Study of School Psychology.

    Social patterning of dietary-related diseases may partly be explained by population disparities in children's diets. This study aimed to determine which early life socioeconomic factors best predict dietary trajectories across childhood. For waves 2-6 of the Baby (B) Cohort (ages 2-3 to 10-11 years) and waves 1-6 of the Kindergarten (K) Cohort (ages 4-5 to 14-15 years) of the Longitudinal Study of Australian Children, we constructed trajectories of dietary scores and of empirically derived dietary patterns. Dietary scores, based on the Australian Dietary Guidelines, summed children's consumption frequencies of seven groups of foods or drinks over the last 24 hours. Dietary patterns at each wave were derived using factor analyses of 12-16 food or drink items. Using multinomial logistic regression analyses, we examined associations of baseline single (parental education, remoteness area, parental employment, income, food security and home ownership) and composite (socioeconomic position and neighbourhood disadvantage) factors with adherence to dietary trajectories. All dietary trajectory outcomes across both cohorts showed profound gradients by composite socioeconomic position but not by neighbourhood disadvantage. For example, odds for children in the lowest relative to highest socioeconomic position quintile being in the 'never healthy' relative to the 'always healthy' score trajectory were OR=16.40, 95% CI 9.40 to 28.61 (B Cohort). Among the single variables, only parental education consistently predicted dietary trajectories. Child dietary trajectories vary profoundly by family socioeconomic position. If causal, reducing dietary inequities may require researching underlying pathways, tackling socioeconomic inequities and targeting health promoting interventions to less educated families. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Background: Urban upbringing is associated with a 2-fold adulthood psychosis risk, and this association replicates for childhood psychotic symptoms. No study has investigated whether specific features of urban neighborhoods increase children’s risk for psychotic symptoms, despite these early psychotic phenomena elevating risk for schizophrenia and other psychiatric disorders in adulthood. Methods: Analyses were conducted on over 2000 children from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative cohort of UK-born twins. Neighborhood-level characteristics were assessed for each family via: a geodemographic discriminator indexing neighborhood-level deprivation, postal surveys of over 5000 residents living alongside the children, and in-home interviews with the children’s mothers. Children were interviewed about psychotic symptoms at age 12. Analyses were adjusted for important family-level confounders including socioeconomic status (SES), psychiatric history, and maternal psychosis. Results: Urban residency at age-5 (OR = 1.80, 95% CI = 1.16–2.77) and age-12 (OR = 1.76, 95% CI = 1.15–2.69) were both significantly associated with childhood psychotic symptoms, but not with age-12 anxiety, depression, or antisocial behavior. The association was not attributable to family SES, family psychiatric history, or maternal psychosis, each implicated in childhood mental health. Low social cohesion, together with crime victimization in the neighborhood explained nearly a quarter of the association between urbanicity and childhood psychotic symptoms after considering family-level confounders. Conclusions: Low social cohesion and crime victimization in the neighborhood partly explain why children in cities have an elevated risk of developing psychotic symptoms. Greater understanding of the mechanisms leading from neighborhood-level exposures to psychotic symptoms could help target interventions for emerging childhood psychotic symptoms

    Rates of child exposure to inter-parental conflict are high and appear to be increasing, with at least one million Australian children affected annually. To-date, there is no established prevalence for inter-parental conflict that includes the more common but less severe forms for young families in the wider Australian community. The current study aims were to examine the prevalence, persistence, and the individual, family and socio-economic context of inter-parental conflict. Data were from four waves of the Baby (n = 4,898) and Kindergarten (n = 4,182) cohorts of the Longitudinal Study of Australian Children. Verbal and physical inter-parental conflict was measured using the Argumentative Relationship Scale. More than 1 in 3 mothers (35-36%) reported any verbal and/or physical conflict. Prevalence of verbal conflict at each wave (10-13%) was higher than physical conflict (4-10%), with low co-occurrence (1-3%). Report of inter-parental conflict at one wave only was most common (19%); although 13% of mothers reported conflict at two waves; and 5-6% reported persistent conflict across three or more waves. Social disadvantage was consistently associated with report at one-wave only and persistent inter-parental conflict. Extrapolated to the Australian population, an estimated 1.9 million children are likely to be affected by inter-parental conflict within any 6 years of the early-to-middle childhood period. Establishing accurate prevalence and understanding the social context of the less severe but most common forms of inter-parental conflict will allow family and child support services to allocate finite resources more effectively and develop targeted interventions to promote children's positive development.

    To determine whether and how longitudinal rates of change in MRI volumetrics, CSF concentrations of Alzheimer-related proteins, molecular imaging of cerebral fibrillar amyloid with PET using the [(11)C] benzothiazole tracer, Pittsburgh compound B (PiB), and cognition were associated among asymptomatic middle-aged to older individuals. Multivariate mixed models for repeated measures were used to assess the correlations on the rates of changes across markers. Among 209 asymptomatic middle-aged to older individuals longitudinally followed for up to 11 years (mean 6.7 years), a faster intraindividual decrease in CSF Aβ42 was associated with a faster increase in PiB mean cortical standardized uptake value ratio (MCSUVR, p = 0.04), but not others. The rate of change in CSF tau (and Ptau181) was correlated with the rate of change in PiB MCSUVR (p = 0.002), hippocampal volume (p = 0.04), and global cognition (p = 0.008). The rate of change in hippocampal volume was correlated with the rate of change in global cognition (p = 0.04). Only 3 significant correlations were observed at baseline: CSF Aβ42 and PiB MCSUVR (p < 0.001), CSF tau and PiB MCSUVR (p < 0.001), and CSF Aβ42 and global cognition (p = 0.01). CSF tau (Ptau181), PiB MCSUVR, and hippocampal volume were all longitudinally correlated with each other, whereas CSF Aβ42 was correlated only with PiB binding. Unlike the baseline values, the longitudinal change in CSF tau (Ptau181) and hippocampal volume were correlated with the longitudinal change in global cognition, validating the role of these biomarkers in Alzheimer disease prevention trials. © 2016 American Academy of Neurology.

We also compared our data with a healthy UK children population from normative data available. Longitudinal study. University Hospital Tertiary Referral Centre. A 4-year follow-up study of 37 children who underwent adenotonsillectomy for obstructive sleep apnoea confirmed on polysomnography. There were 19 boys and 18 girls from our initial cohort. The primary caregiver completed the validated Child Health Questionnaire Parental Form version-28, 4 years after initial surgery. Our control group consist of 221 healthy children aged 6-18 that were included as 'normal' controls in a study looking at children with juvenile arthritis. The children were defined as healthy by a physician and/or after declaration by the parent. Child Health Questionnaire Parental Form version-28 scores. A total of 33 patients (89%) from our initial cohort were contacted. The mean age was 10.6 (median, 11; range, 5-16). When compared with results obtained 3 months postoperatively, the mean scores were higher in five domains and were statistically significant in three subscales (Role Limitations P < 0.00001; Bodily Pain P < 0.002; and Global Health P < 0.02). There was a significant deterioration in Behaviour subscale (P < 0.0007) in spite of surgery. Compared with controls, 4-year follow-up scores were higher in five domains with the Global Health domain (P < 0.0004) being statistically significant. When the 4-year follow-up scores were compared with preoperative values, these were higher in all 13 domains with statistically significant improvements in nine domains, indicating that improvements had persisted 4 years after surgery. At 4 years, however, the means scores in many domains remain lower when

    Background In asthma management guidelines the primary goal of treatment is asthma control. To date, asthma control, guided by symptoms and lung function, is not optimal in many children and adults. Direct monitoring of airway inflammation in exhaled breath may improve asthma control and reduce the number of exacerbations. Aim 1) To study the use of fractional exhaled nitric oxide (FeNO) and inflammatory markers in exhaled breath condensate (EBC), in the prediction of asthma exacerbations in a pediatric population. 2) To study the predictive power of these exhaled inflammatory markers combined with clinical parameters. Methods 96 asthmatic children were included in this one-year prospective observational study, with clinical visits every 2 months. Between visits, daily symptom scores and lung function were recorded using a home monitor. During clinical visits, asthma control and FeNO were assessed. Furthermore, lung function measurements were performed and EBC was collected. Statistical analysis was performed using a test dataset and validation dataset for 1) conditionally specified models, receiver operating characteristic-curves (ROC-curves); 2) k-nearest neighbors algorithm. Results Three conditionally specified predictive models were constructed. Model 1 included inflammatory markers in EBC alone, model 2 included FeNO plus clinical characteristics and the ACQ score, and model 3 included all the predictors used in model 1 and 2. The area under the ROC-curves was estimated as 47%, 54% and 59% for models 1, 2 and 3 respectively. The k-nearest neighbors predictive algorithm, using the information of all the variables in model 3, produced correct predictions for 52% of the exacerbations in the validation dataset. Conclusion The predictive power of FeNO and inflammatory markers in EBC for prediction of an asthma exacerbation was low, even when combined with clinical characteristics and symptoms. Qualitative improvement of the chemical analysis of EBC may lead to a

    To assess whether puberty and physical growth vary in obese when compared to normal-weight children. One hundred obese pre-pubertal children (44 boys; mean age (±SD): 9.01 ± 0.62 years; 56 girls; 8.70 ± 0.57 years) were compared to 55 normal-weight controls (27 boys; 9.17 ± 0.26 years; 28 girls; 8.71 ± 0.62 years). All study participants were followed prospectively with 6-monthly follow-up visits. At each study visit, height, weight, body mass index (BMI) and pubertal stage were assessed. Obese children entered puberty and achieved later stages of puberty earlier than controls (onset of puberty: boys: 11.66 ± 1.00 vs. 12.12 ± 0.91 years, P = 0.049; girls: 9.90 ± 0.78 vs. 10.32 ± 1.70, P = 0.016; late puberty: boys: 13.33 ± 0.71 vs. 14.47 ± 1.00 years, P < 0.001; girls: 11.54 ± 0.99 vs. 12.40 ± 1.02, P = 0.001). Pre-pubertal BMI standard deviation score (SDS) was inversely associated with both age at the onset of puberty (β = -0.506, P < 0.001) and age at late puberty (β = -0.514, P < 0.001). Obese children also showed an earlier age at peak height velocity (PHV) (boys: 12.62 ± 0.82 vs. 13.19 ± 0.96 years, P = 0.01; girls: 11.37 ± 0.89 vs. 12.77 ± 0.76, P < 0.001) and a lower PHV (boys: 7.74 ± 1.49 vs. 9.28 ± 1.64 cm year(-1) , P < 0.001; girls: 7.60 ± 1.64 vs. 8.29 ± 1.03, P = 0.03). Height SDS progressively declined over the study period in the obese group (P for trend <0.001), whereas there were no significant changes in the control group (P for trend = 0.5). Obese boys and girls presented an earlier onset of puberty and completion of puberty and an impaired height gain during puberty. © 2013 The Authors.

    This study examines whether intervention-induced changes in mother-child relationship quality and discipline led to short-term (6 months) and long-term (6 years) changes in children's coping processes in a sample of 240 youth aged 9-12 years when assessed initially. Data were from a randomized, experimental trial of a parenting-focused preventive intervention designed to improve children's postdivorce adjustment. Three-wave prospective mediational analyses revealed that intervention-induced improvements in relationship quality led to increases in coping efficacy at 6 months and to increases in coping efficacy and active coping at 6 years. Tests of the mediated effects were significant for all 3 indirect paths. Results are discussed in terms of pathways to adaptive coping and implications for the implementation of preventive interventions targeting coping.

    Although much is now known about the effects of intrauterine growth retardation (IUGR) on children born SGA with regard to anthropometric and biochemical parameters and their treatment, there are still many gaps associated with its impact on neurocognitive functions. In our experience published several years ago, IUGR has a negative effect on neurocognitive development, regardless of whether these children showed evidence of catch-up growth or not or of the socio-economic conditions that might contribute to the situation. We have now accumulated a large number of cases, many of whom have been followed longitudinally, some for up to 7 years, many having been treated with GH from the time when this therapy was first approved by the EMA. Apart from the cases mentioned, other confounding factors such as gestational age, Apgar score, neonatal comorbidity and the possible effects of GH treatment have also been included. In addition and using our own reference standards, we now present our experience, which confirms what we had already noted in the past, that IUGR is in itself a condition that often causes psychomotorintellectual impairment, may be extremely severe and tends to worsen. This negative impact of IUGR on neurocognitive development does not depend on how the child grows,spontaneous growth is better and when growth is not altered by GH therapy. Later studies will be able to confirm whether early treatment with GH throughout the 2nd year of life, or an early specific stimulation programme, or the sum of both, can improve the neurocognitive development of these children. IUGR prevention, acting on causal factors that are partly avoidable such as smoking, working conditions and stress during pregnancy (see the corresponding article in this supplement) proves once again to be the best way to stop this negative impact on the IQ of many children born SGA.

    2014-01-01

    Background It is unknown whether childhood physical development in Asian populations differs from western populations, since no longitudinal analysis has been performed in Asian countries yet. Utilizing the 21st Century Longitudinal Survey in Newborns, we studied the timing of adiposity rebound (AR) among Japanese children and determined whether AR occurs earlier in obese children compared to nonobese children. Furthermore, we identified important demographic, social, and lifestyle factors that affect their physical development. Methods We used data from the annual surveillance of Japanese children born in 2001, with 45,392 eligible subjects. We applied survival analysis to evaluate the AR and a trajectory method for the BMI transition across 5 ½ years. Time-dependent and time-independent factors affecting BMI changes were investigated using longitudinal analysis. Accounting for the known difference in prevalence between Japanese and Western children, we adopted a 95th percentile of BMI as criterion for obesity. Results Mean BMI at birth and at ages 1 ½, 2 ½, 3 ½, 4 ½, and 5 ½ years for all subjects were 12.6, 16.3, 16.1, 15.8, 15.5, and 15.4, respectively, showing a progressive reduction after 1 ½ years. However, among obese children at 5 ½ years, 39.6% had experienced AR as early as at age 4 ½ years. Controlling for sex, Cox’s proportional hazards model showed that obese children had a 48.5% higher hazard to experience AR than nonobese children. The difference in BMI transition between obese and non-obese children was also captured by a trajectory method. In longitudinal analysis, BMI was lower for children who had a longer gestational period whereas children who received parental care from non-family members gained higher BMI values. Conclusions With the 95th percentile cutoff for children obesity, obese Japanese children developed AR earlier than nonobese Japanese children, similar to those in Western countries reported in the literature

    Tobacco products use is the leading cause of chronic diseases morbidity and mortality. This study explores an exposure to tobacco advertisements factors and knowledge, an association with snuff/pipe usage and cigarette smoking among Ellisras rural children aged between 11 to 18 years. A total of 1654 subjects (854 boys and 800 girls) who were part of the Ellisras Longitudinal Study completed the questionnaire. A significant (p < 0.05) number of boys (11.7%) compared to girls (8.8%) received free cigarettes from the members of the community. Bill boards were successful in advertising tobacco products among the Ellisras rural boys (17% boys and 12.8% for girls, p < 0.022). Multivariate analyses found significant association between cigarette smoking (OR = 1.7 95%CI 1.1-2.7 and Model 2 OR 1.6 95%CI 1.0-2.6 adjusted for age and gender) and advertisements of tobacco products on the TV screens, videos or movies. Exposure to tobacco products advertisements was high among Ellisras rural children. Though tobacco products legislation exists in South Africa, efforts should be taken by the health professionals to emphasize the danger of using tobacco products even among the illiterate. Teachers and parents should refrain from advertising tobacco products at schools and at homes.

Autoregressive latent trajectory models revealed that maternal and paternal corporal punishment predicted subsequent children's externalizing behavior (parent-driven effects), whereas children's externalizing behavior predicted subsequent maternal and paternal psychological aggression (child-driven effects). The parent-driven effects became stronger, whereas the child-driven effects were equally strong across time. Furthermore, the parent-driven effects for corporal punishment were found for both boys and girls, whereas the child-driven effects for psychological aggression were found only for boys.

    Background Parenting and children’s adjustment were examined in 30 surrogacy families, 31 egg donation families, 35 donor insemination families, and 53 natural conception families. Methods Parenting was assessed at age 3 by a standardized interview designed to assess quality of parenting and by questionnaire measures of anxiety, depression and marital quality. Children’s adjustment was assessed at ages 3, 7 and 10 using the Strengths and Difficulties Questionnaire (SDQ). Results Although children born through reproductive donation obtained SDQ scores within the normal range, surrogacy children showed higher levels of adjustment difficulties at age 7 than children conceived by gamete donation. Mothers who had kept their child’s origins secret showed elevated levels of distress. However, maternal distress had a more negative impact on children who were aware of their origins. Conclusions The absence of a gestational connection to the mother may be more problematic for children than the absence of a genetic link. PMID:23176601

    The purpose of this study was to use data from a population-based survey to evaluate the association between childhood epilepsy and social outcomes through tests of mathematics skills, and sense of general self-esteem (GSS). Using data from Cycles 1 to 8 of the National Longitudinal Survey of Children and Youth (NLSCY), Hierarchical linear modeling (HLM) was used to compare baseline math scores and changes in math scores and sense of general self esteem (GSS) over time in children with and without epilepsy. Scores of Health Utility Index (HUI) were factored into the analysis. Children with epilepsy do not significantly differ in their scaled math scores in comparison to their peers without epilepsy, at age 12; however, in the two level HLM model the children with epilepsy lagged behind the healthy comparison group in terms of their growth in acquiring knowledge in mathematics. Additionally, when children with epilepsy carry an added health impairment as measured by an imperfect health utility (HUI) score the group shows a slower rate of growth in their math scores over time. Self-esteem measures show variable effects in children with epilepsy alone, and those with added health impairments. The interaction with HUI scores shows a significant negative effect on self-esteem, when epilepsy is associated with added health impairment. The findings suggest that the population of Canadian children surveyed with epilepsy are vulnerable to poorer academic outcomes in mathematics in later years, and this problem is compounded further with the presence of other additional health impairments.

    WNK1 gene variants have been associated with adult blood pressure. We aimed to investigate relationships between WNK1 variants and blood pressure, as well as blood pressure change with age, in a longitudinal childhood study. Associations between single nucleotide polymorphisms in WNK1 and blood pressure and the rate of blood pressure change between 7 and 11 years were examined in the Avon Longitudinal Study of Parent and Children Study (n=5326 for systolic blood pressure at 11 years). We observed associations (P<0.05) with diastolic blood pressure gradient with age for 33 of 82 typed and imputed polymorphisms, including polymorphisms in exons 4, 10, and 11 (rs10774466, rs1012729, and rs9804992). The minor allele (G) of rs1012729 (frequency: 25.6%) was associated with a gender-adjusted change in a diastolic blood pressure gradient of -0.11 mm Hg/y (95% CI: -0.20 to -0.03 mm Hg/y; P=0.0054). No associations were shown with the systolic blood pressure gradient. At age 11 years, 30 polymorphisms showed association (P<0.05) with systolic blood pressure, including variants in exons 4 and 10 (rs10774466 and rs1012729). Only 3 polymorphisms were associated with diastolic blood pressure at 11 years. In exploration of polymorphism-dietary cation interactions on systolic blood pressure at 11 years, 59 reached significance (P<0.05; 12.3 expected by chance), mostly (n=33) related to dietary calcium. The findings show that common intronic and exonic WNK1 variants are associated with diastolic blood pressure gradient from 7 to 11 years and with systolic blood pressure at 11 years. Our study suggests that previously reported effects of WNK1 variants on blood pressure are mediated via effects on the gradient of blood pressure change with age.

    It is often hypothesised that neighbourhood green space may help prevent well-known declines in physical activity and increases in sedentary behaviour that occur across childhood. As most studies in this regard are cross-sectional, the purpose of our study was to use longitudinal data to examine whether green space promotes active lifestyles as children grow older. Data came from participants (n = 4983; age = 4-5) of the Longitudinal Study of Australian Children, a nationally representative study on health and child development. Physical activity and screen time were measured biennially (2004-2012) using questionnaires and time use diaries. Quantity of neighbourhood green space was objectively measured using Australian Bureau of Statistics mesh block data for each participant's statistical area level 2. Multilevel regression was used to test for associations between physical activity and screen time with green space quantity, adjusting for socio-economic confounders. Boys living in areas with 10% more neighbourhood green space had a: 7% (95% CI = 1.02, 1.13) greater odds of choosing physically active pastimes; 8% (95 % CI = 0.85, 1.00) lower odds of not enjoying physical activity; 2.3 min reduction in weekend television viewing (95% CI = -4.00, -0.69); and 7% (95% CI = 1.02; 1.12) and 9% (95% CI = 1.03; 1.15) greater odds of meeting physical activity guidelines on weekdays and weekends, respectively. No statistically (or practically) significant results were observed for girls. Current provisions of neighbourhood green space may be more amenable to promoting active lifestyles among boys than girls. Research is needed to explore what types of green space promote active lifestyles in all children.

    In this 8-year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred sixty-four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept-slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high-high (with a large initial vocabulary size and a fast growth rate), low-high (with a small initial vocabulary size and a fast growth rate) and low-low (with a small initial vocabulary size and a slow growth rate) groups. Low-high and low-low groups were distinguishable mostly through phonological skills, morphological skills and other reading-related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language-related and reading-related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development.

    Childhood obesity is high on the global public health agenda. Although risk factors are well known, the influence of social risk on the therapeutic outcome of lifestyle intervention is poorly examined. This study aims to investigate the influence of migration background, low education, and parental unemployment. 62,147 patients participated in multidimensional lifestyle intervention programs in 179 pediatric obesity centers. Data were collected using standardized software for longitudinal multicenter documentation. 12,305 (19.8%) attended care for 6-24 months, undergoing an intensive therapy period and subsequent follow-ups for up to 3 years. A cumulative social risk score was calculated based on different risk indicators. Migration background, low education, and parental employment significantly influenced the outcome of lifestyle intervention. The observed BMI-SDS reduction was significantly higher in the subgroup with low social risks factors (Δ BMI-SDS -0.19) compared to those presenting moderate (Δ BMI-SDS -0.14) and high social risk (Δ BMI-SDS -0.11). Our data underline the effect of children's social setting on the outcome of multidimensional lifestyle intervention. The presence of a high social risk burden is a negative predictor for successful weight loss. Specific therapeutic programs need to be developed for disadvantaged children and adolescents.

    Osteonecrosis after hematopoietic stem cell transplantation (HCT) has seldom been addressed in pediatric populations. At our institution, since January 2002, children undergoing allogeneic HCT (alloHCT) receive yearly follow-up magnetic resonance imaging (MR) of hips and knees. To estimate the prevalence, longitudinal changes and associated risk factors for osteonecrosis after alloHCT, we reviewed MRs for children who underwent single alloHCT during the study period. We analyzed 149 of 344 patients who had post HCT MRI imaging performed [84 males; median age11 years (range, 0.5–21years)], median follow-up time was 32.6 months (range, 2.8–97.2 months). Forty-four (29.5%) developed osteonecrosis of hips and/or knees; of those, 20 (45%) had at least 30% epiphyseal involvement. In 23 (52%) osteonecrosis lesions were identified in the first, and 43 (98%) by the third yearly scan. Knees were more frequently involved than hips; severity of osteonecrosis was greater in hips. Those who had pre-alloHCT osteonecrosis, two patients’ hips and six patients’ knees resolved completely; three patients’ osteonecrosis lesions regressed after alloHCT. On risk factor analysis, age at time of alloHCT (p=0.051) and osteonecrosis identified by MRs before alloHCT (p=0.001) were the primary risk factors. This analysis shows that preventive strategies for osteonecrosis in this population should focus on measures to minimize risk factors before alloHCT. PMID:22158389

    Respiratory viral infections are an important cause of morbidity in patients with chronic respiratory diseases, such as cystic fibrosis (CF). We hypothesized that patients with CF are more susceptible to human rhinovirus (HRV) infections than healthy controls. In a 6-month winter period, 20 young children with CF (0-7 years) and 18 age-matched healthy controls were sampled biweekly for HRV-polymerase chain reaction using nasopharyngeal swabs, irrespective of respiratory symptoms. Respiratory symptoms were scored twice a week. If any symptom was present, an additional sample was obtained. All HRV-positive samples were genotyped to distinguish HRV subtypes. We analyzed 645 samples, with comparable total numbers of samples in both groups. HRV was detected in 40.8% of all analyzed samples. Children with CF had significantly more HRV-positive samples compared with healthy controls, with a mean number (± standard deviation) of 8.1 ± 2.3 versus 5.7 ± 2.9 positive samples per individual (P < 0.01). Prolonged detection (>2 weeks) with the same HRV subtype occurred more frequently in the CF patients (P < 0.01). The genetic distribution and pattern of phylogenetic diversity of the different HRV subtypes were similar in both groups. This is the first in vivo longitudinal study showing that HRV is detected more frequently and persists for longer periods in CF patients compared with healthy controls. This might indicate increased viral replication and/or decreased antiviral defense in patients with CF.

    Associations between maternal age in pregnancy and offspring blood pressure (BP) at age 7(1/2) were investigated in 7623 singletons from the Avon Longitudinal Study of Parents and Children (ALSPAC). In models adjusted for age and sex there was an inverse relationship between maternal age and BP in children: beta = -0.06 mmHg per year of maternal age (95% CI -0.10 to -0.01, P = 0.02) for systolic BP and beta = -0.04 (95% CI -0.07 to -0.01, P = 0.02) for diastolic BP. However, this association disappeared after adjustment for confounding factors: beta = -0.02 mmHg per year of maternal age (95% CI -0.07 to 0.04, P = 0.5) for systolic BP and beta = -0.03 (95% CI -0.07 to 0.01, P = 0.2) for diastolic BP. We conclude that there is no evidence of a relationship between maternal age in pregnancy and childhood BP in this contemporary birth cohort.

    The author followed 56 internationally adopted children during the first 3 years after adoption to determine how and when they reached age-expected language proficiency in Standard American English. The influence of age of adoption was measured, along with the relationship between early and later language and speech outcomes. Children adopted from Eastern Europe at ages 12 months to 4 years, 11 months, were assessed 5 times across 3 years. Norm-referenced measures of receptive and expressive language and articulation were compared over time. In addition, mean length of utterance (MLU) was measured. Across all children, receptive language reached age-expected levels more quickly than expressive language. Children adopted at ages 1 and 2 "caught up" more quickly than children adopted at ages 3 and 4. Three years after adoption, there was no difference in test scores across age of adoption groups, and the percentage of children with language or speech delays matched population estimates. MLU was within the average range 3 years after adoption but significantly lower than other language test scores. Three years after adoption, age of adoption did not influence language or speech outcomes, and most children reached age-expected language levels. Expressive syntax as measured by MLU was an area of relative weakness.

    Lower socioeconomic position (SEP) predicts higher cardiovascular risk in adults. Few studies differentiate between neighborhood and family SEP or have repeated measures through childhood, which would inform understanding of potential mechanisms and the timing of interventions. We investigated whether neighborhood and family SEP, measured biennially from ages 0 to 1 year onward, was associated with carotid intima-media thickness (IMT) at ages 11 to 12 years. Data were obtained from 1477 families participating in the Child Health CheckPoint study, nested within the Longitudinal Study of Australian Children. Disadvantaged family and neighborhood SEP was cross-sectionally associated with thicker maximum carotid IMT in separate univariable linear regression models. Associations with family SEP were not attenuated in multivariable analyses, and associations with neighborhood SEP were attenuated only in models adjusted for family SEP. The difference in maximum carotid IMT between the highest and lowest family SEP quartile measured at ages 10 to 11 years was 10.7 μm (95% CI, 3.4-18.0; P=0.004), adjusted for age, sex, pubertal status, passive smoking exposure, body mass index, blood pressure, and arterial lumen diameter. In longitudinal analyses, family SEP measured as early as age 2 to 3 years was associated with maximum carotid IMT at ages 11 to 12 years (difference between highest and lowest quartile: 8.5 μm; 95% CI, 1.3-15.8; P=0.02). No associations were observed between SEP and mean carotid IMT. We report a robust association between lower SEP in early childhood and carotid IMT in mid-childhood. Further investigation of mechanisms may inform pediatric cardiovascular risk assessment and prevention strategies. © 2017 The Authors.

    The aim of this study was to compare changes in dental arch morphology between patients with Crouzon syndrome or Apert syndrome and controls. Children between 4 and 14 yr of age with Crouzon syndrome (n = 40) or Apert syndrome (n = 28) were compared with non-syndromic controls (n = 457) in terms of arch widths, depths, and length dimensions. Multilevel statistical modeling techniques were used to evaluate changes over time. Dental arch dimensions were found to be smaller in patients with Crouzon syndrome or Apert syndrome compared with control subjects. Maxillary intercanine width for patients with Apert syndrome were increased, whilst other arch width variables showed no change. Patients with Crouzon syndrome showed increases in maxillary intercanine width, whilst intermolar width showed no change over time. Dental arch dimensions in syndromic patients were thus found to be consistently smaller than in control subjects between 4 and 14 yr of age, implying that patients with Crouzon syndrome and Apert syndrome had a diminished growth potential. © 2013 Eur J Oral Sci.

    Aims Oral language is the foundation of literacy. Naturally, policies and practices to promote children’s literacy begin in early childhood and have a strong focus on developing children’s oral language, especially for children with known risk factors for low language ability. The underlying assumption is that children’s progress along the oral to literate continuum is stable and predictable, such that low language ability foretells low literacy ability. This study investigated patterns and predictors of children’s oral language and literacy abilities at 4, 6, 8 and 10 years. The study sample comprised 2,316 to 2,792 children from the first nationally representative Longitudinal Study of Australian Children (LSAC). Six developmental patterns were observed, a stable middle-high pattern, a stable low pattern, an improving pattern, a declining pattern, a fluctuating low pattern, and a fluctuating middle-high pattern. Most children (69%) fit a stable middle-high pattern. By contrast, less than 1% of children fit a stable low pattern. These results challenged the view that children’s progress along the oral to literate continuum is stable and predictable. Findings Multivariate logistic regression was used to investigate risks for low literacy ability at 10 years and sensitivity-specificity analysis was used to examine the predictive utility of the multivariate model. Predictors were modelled as risk variables with the lowest level of risk as the reference category. In the multivariate model, substantial risks for low literacy ability at 10 years, in order of descending magnitude, were: low school readiness, Aboriginal and/or Torres Strait Islander status and low language ability at 8 years. Moderate risks were high temperamental reactivity, low language ability at 4 years, and low language ability at 6 years. The following risk factors were not statistically significant in the multivariate model: Low maternal consistency, low family income, health care card

    Friedreich’s ataxia is the most common autosomal recessive form of neurodegenerative ataxia. We present a longitudinal study on the gait pattern of children and adolescents affected by Friedreich’s ataxia using Gait Analysis and the Scale for the Assessment and Rating of Ataxia (SARA). We assessed the spectrum of changes over 12 months of the gait characteristics and the relationship between clinical and instrumental evaluations. We enrolled 11 genetically confirmed patients affected by Friedreich’s ataxia in this study together with 13 normally developing age-matched subjects. Eight patients completed a 12-month follow-up under the same protocol. By comparing the gait parameters of Friedreich’s ataxia with the control group, we found significant differences for some relevant indexes. In particular, the increased knee and ankle extension in stance revealed a peculiar biomechanical pattern, which correlated reliably with SARA Total, Gait and Sitting scores. The knee pattern showed its consistency also at the follow-up: Knee extension increased from 6.8±3.5° to -0.5±3.7° and was significantly correlated with the SARA total score. This feature anticipated the loss of the locomotor function in two patients. In conclusion, our findings demonstrate that the selective and segmental analysis of kinetic/kinematic features of ataxic gait, in particular the behavior of the knee, provides sensitive measures to detect specific longitudinal and functional alterations, more than the SARA scale, which however has proved to be a reliable and practical assessment tool. Functional outcomes measures integrated by instrumental evaluation increase their sensitivity, reliability and suitability for the follow-up of the disease progression and for the application in clinical trials and in rehabilitative programs.

    Recent advances in human neuroimaging research have revealed that white-matter connectivity can be described in terms of an integrated network, which is the basis of the human connectome. However, the developmental changes of this connectome in childhood are not well understood. This study made use of two independent longitudinal diffusion-weighted imaging data sets to characterize developmental changes in the connectome by estimating age-related changes in fractional anisotropy (FA) for reconstructed fibers (edges) between 68 cortical regions. The first sample included 237 diffusion-weighted scans of 146 typically developing children (4-13 years old, 74 females) derived from the Pediatric Longitudinal Imaging, Neurocognition, and Genetics (PLING) study. The second sample included 141 scans of 97 individuals (8-13 years old, 62 females) derived from the BrainTime project. In both data sets, we compared edges that had the most substantial age-related change in FA to edges that showed little change in FA. This allowed us to investigate if developmental changes in white matter reorganize network topology. We observed substantial increases in edges connecting peripheral and a set of highly connected hub regions, referred to as the rich club. Together with the observed topological differences between regions connecting to edges showing the smallest and largest changes in FA, this indicates that changes in white matter affect network organization, such that highly connected regions become even more strongly imbedded in the network. These findings suggest that an important process in brain development involves organizing patterns of inter-regional interactions.

    To apply survival analysis to a longitudinal study of the relationship between salivary mutans streptococci (MS) levels at baseline in initially caries-free children and caries onset in deciduous, mixed, and permanent dentition. The Kaplan-Meier survival analysis method was used to compare survival times to caries onset for initially caries-free children with low levels of MS at baseline with survival times to caries onset for initially caries-free children with high levels of MS at baseline. Data from a 6-year longitudinal study of caries risk in initially caries-free children in Rochester and the Finger Lakes Region of western New York were utilized for this study. Of 464 children analyzed, 327 had a low level of MS and 137 had a high level of MS at baseline. Survival analyses showed that children with a low level of MS at baseline remained caries-free for a longer period than children with a high level of MS at baseline. Statistically significant relationships [hazard ratios (HR)] with onset of caries in deciduous, mixed and permanent teeth were found with high and low levels of salivary MS. Based on our analysis, we concluded that children who were caries-free at baseline and who had high salivary MS levels at baseline would be at greater risk, i.e. more susceptible to caries onset, at any given time than caries-free children who had low salivary MS levels at baseline. Survival functions for deciduous, mixed and permanent dentitions with their 95% confidence limits have been calculated. Survival analysis for the exploration of longitudinal caries studies has an advantage over traditional statistical methods, as it takes into account censored observations and incorporates the concept of risk over time. Hence, survival analysis is well suited for studying transitions from one health state to another, in this case, from a caries-free state to a caries-active state.

    Elucidating the cellular and molecular basis of naturally acquired immunity to Plasmodium falciparum infection would assist in developing a rationally based malaria vaccine. Innate, intermediate, and adaptive immune mechanisms are all likely to contribute to immunity. Interferon-gamma (IFN-gamma) has been implicated in both protection against and the pathogenesis of malaria in humans. In addition, considerable heterogeneity exists among rapid IFN-gamma responses to P. falciparum in malaria-naive donors. The question remains whether similar heterogeneity is observed in malaria-exposed individuals and whether high, medium, or low IFN-gamma responsiveness is differentially associated with protective immunity or morbidity. A 6-month longitudinal cohort study involving 206 school-aged Papua New Guinean children was performed. Peripheral blood mononuclear cells collected at baseline were exposed to live P. falciparum-infected erythrocytes. Early IFN-gamma responses were measured, and IFN-gamma-expressing cells were characterized by flow cytometry. IFN-gamma responsiveness was then tested for associations with parasitological and clinical outcome variables. Malaria-specific heterogeneity in early IFN-gamma responsiveness was observed among children. High-level early IFN-gamma responses were associated with protection from high-density and clinical P. falciparum infections. Parasite-induced early IFN-gamma was predominantly derived from gammadelta T cells (68% of which expressed the natural killer marker CD56) and alphabeta T cells, whereas natural killer cells and other cells made only minor contributions. The expression of CD56 in malaria-responsive, IFN-gamma-expressing gammadelta T cells correlated with IFN-gamma responsiveness. High, early IFN-gamma production by live parasite-stimulated peripheral blood mononuclear cells is a correlate of immunity to symptomatic malaria in Papua New Guinean children, and natural killer-like gammadelta T cells may contribute to

    Siblings of children with chronic illness and disabilities are at increased risk of negative psychological effects. Support groups enable them to access psycho-education and social support. Barriers to this can include the distance they have to travel to meet face-to-face. Audio-conferencing, whereby three or more people can connect by telephone in different locations, is an efficient means of groups meeting and warrants exploration in this healthcare context. This study explored the feasibility of audio-conferencing as a method of facilitating sibling support groups. A longitudinal design was adopted. Participants were six siblings (aged eight to thirteen years) and parents of children with complex neurodevelopmental disorders attending the Centre for Interventional Paediatric Psychopharmacology (CIPP). Four of the eight one-hour weekly sessions were held face-to-face and the other four using audio-conferencing. Pre- and post-intervention questionnaires and interviews were completed and three to six month follow-up interviews were carried out. The sessions were audio-recorded, transcribed and thematic analysis was undertaken. Audio-conferencing as a form of telemedicine was acceptable to all six participants and was effective in facilitating sibling support groups. Audio-conferencing can overcome geographical barriers to children being able to receive group therapeutic healthcare interventions such as social support and psycho-education. Psychopathology ratings increased post-intervention in some participants. Siblings reported that communication between siblings and their family members increased and siblings' social network widened. Audio-conferencing is an acceptable, feasible and effective method of facilitating sibling support groups. Siblings' clear accounts of neuropsychiatric symptoms render them reliable informants.

    Patterns of relative and absolute stability in parental behaviour with children and adolescents are reported. The sample comprised 523 youth (58.7% girls). Data were collected at three time periods: T1 (M age = 11.1 yr.), T2 (M age = 12.2 yr.), and T3 (M age = 13.2 yr.), each separated by one year. According to children's reports, relative consistency was moderate in both mothers and fathers, particularly as regards communication and strict control. In contrast, as children got older, parental rearing practices related to strict control and hostility decreased. There was a similarity between fathers and mothers in terms of relative and absolute stability. Relative stability was affected by the child's sex, the parenting variable, and the time period; however, the patterns of absolute stability reveal no differences by sex.

    The causes of autism likely involve genetic and environmental factors that influence neurobiological changes and the neurological and behavioral features of the disorder. Immune factors and inflammation are hypothesized pathogenic influences, but have not been examined longitudinally. In a cohort of 104 participants with autism, we performed an assessment of immune mediators such as cytokines, chemokines, or growth factors in serum and cerebrospinal fluid (n = 67) to determine potential influences of such mediators in autism. As compared with 54 typically developing controls, we found no evidence of differences in the blood profile of immune mediators supportive of active systemic inflammation mechanisms in participants with autism. Some modulators of immune function (e.g., EGF and soluble CD40 ligand) were increased in the autism group; however, no evidence of group differences in traditional markers of active inflammation (e.g., IL-6, TNFα, IL-1β) were observed in the serum. Further, within-subject stability (measured by estimated intraclass correlations) of most analytes was low, indicating that a single measurement is not a reliable prospective indicator of concentration for most analytes. Additionally, in participants with autism, there was little correspondence between the blood and CSF profiles of cytokines, chemokines, and growth factors, suggesting that peripheral markers may not optimally reflect the immune status of the central nervous system. Although the relatively high fraction of intrathecal production of selected chemokines involved in monocyte/microglia function may suggest a possible relationship with the homeostatic role of microglia, control data are needed for further interpretation of its relevance in autism. These longitudinal observations fail to provide support for the hypothesized role of disturbances in the expression of circulating cytokines and chemokines as an indicator of systemic inflammation in autism.

    Objective To examine dental caries development and caries risk factors among preschool African-American children from low-income families in Detroit, Michigan over a four- year window. Methods Data came from a representative sample of 1,021 children (zero to five years) and their caregivers in Detroit. The baseline participants in 2002–03 (W1) were reexamined in 2004–05 (W2) and 2007 (W3). Caries was measured using the International Caries Detection and Assessment System. Bivariate and multivariate analyses for repeated data were conducted to explore associations between caries increment outcomes and demographics, access to dental care, oral health-related behaviors, and social and physical environments. Results The mean number of new NCCL (non-cavitated caries lesions) was 2.8 between W1 and W2 and 2.6 between W2 and W3, while the mean number of new CCL (cavitated caries lesions) was 2.0 and 2.0, respectively, during the same time periods. In younger children (< three years old in W1) higher number of new NCCL than new CCL were observed in both W1–W2 and W2–W3. The risk of new NCCL was associated with child’s soda intake and caregiver’s age. For the risk of new CCL, significant risk factors included baseline NCCL, baseline CCL, as well as child’s age. Baseline caries and child’s soda intake were also associated with the risk of developing new decayed, missing, and filled tooth surfaces. Conclusions Higher number of new NCCL relative to CCL was developed among low-income Africa-American children during early childhood. New caries development was associated with baseline caries and child’s soda intake. PMID:25441657

    Millions of children were exposed to major earthquake in China, with serious psychological and developmental consequences. To obtain accurate rate of post-disaster related disorder and identify predictors may help inform post-disaster rescue and rehabilitation efforts. The present longitudinal study explored correlations of demographic and socioeconomic characteristics of juvenile survivors of the Ya'an and Wenchuan earthquakes in China with their trajectories of post-disaster related disorder. A total of 435 Chinese children and adolescents who survived the 2013 Ya'an earthquake were recruited from six primary, secondary and high schools in Baoxing County. All survivors were assessed at 12months after the disaster, when a trained psychiatrist assessed mental health problems in a face-to-face structured interview, and 153 survivors were followed up at 30months after the earthquake via telephone. The 12-month assessment indicated a post-traumatic stress disorder (PTSD) prevalence of 43.9% as well as depression (20.9%) or the criteria for both PTSD and depression (18.2%) and the other disorder (0.9%). The 30-month assessment indicated that 15.7% of subjects met the criteria for PTSD, 21.6% met the criteria for depression. No subjects met the criteria for other affective or anxiety disorders. Significant predictors of PTSD and depression were death in the family, previous earthquake experience, a poor parent-child relationship and economic pressure or poverty. Clinical interview face to face is quite different from via telephone and the attrition rate in the longitudinal cohort is high, which would directly affect our results of the assessment. PTSD and depression may be as prevalent and persistent in disaster victims in China as elsewhere, and high co-comorbidities remain poorly understood. Although many adolescents recover over time, some exhibit chronic, delayed-onset PTSD and depression, especially those with poor relationships with their parents or those living

    There is increasing public and scientific concern regarding the long-term behavioural effects of video game use in children, but currently little consensus as to the nature of any such relationships. We investigated the relationship between video game use in children, degree of violence in games, and measures of depression and a 6-level banded measure of conduct disorder. Data from the Avon Longitudinal Study of Parents and Children were used. A 3-level measure of game use at age 8/9 years was developed, taking into account degree of violence based on game genre. Associations with conduct disorder and depression, measured at age 15, were investigated using ordinal logistic regression, adjusted for a number of potential confounders. Shoot-em-up games were associated with conduct disorder bands, and with a binary measure of conduct disorder, although the strength of evidence for these associations was weak. A sensitivity analysis comparing those who play competitive games to those who play shoot-em-ups found weak evidence supporting the hypothesis that it is violence rather than competitiveness that is associated with conduct disorder. However this analysis was underpowered, and we cannot rule out the possibility that increasing levels of competition in games may be just as likely to account for the observed associations as violent content. Overall game exposure as indicated by number of games in a household was not related to conduct disorder, nor was any association found between shoot-em-up video game use and depression.

    Background Salamanca, Mexico occupied fourth place nationally in contaminating emissions. The aim of the study was to determine the impact of air pollution on the frequency of pulmonary function alterations and respiratory symptoms in school-age children in a longitudinal repeated-measures study. Methods We recruited a cohort of 464 children from 6 to 14 years of age, from two schools differing in distance from the major stationary air pollution sources. Spirometry, respiratory symptoms and air pollutants (O3, SO2, NO, NO2, NOx, PM10,) were obtained for each season. Mixed models for continuous variables and multilevel logistic regression for respiratory symptoms were fitted taking into account seasonal variations in health effects according to air pollution levels. Results Abnormalities in lung function and frequency of respiratory symptoms were higher in the school closer to major stationary air pollution sources than in the distant school. However, in winter differences on health disappeared. The principal alteration in lung function was the obstructive type, which frequency was greater in those students with greater exposure (10.4% vs. 5.3%; OR = 1.95, 95% CI 1.0-3.7), followed by the mixed pattern also more frequent in the same students (4.1% vs. 0.9%; OR = 4.69, 95% CI, 1.0-21.1). PM10 levels were the most consistent factor with a negative relationship with FVC, FEV1 and PEF but with a positive relationship with FEV1/FVC coefficient according to its change per 3-month period. Conclusions Students from the school closer to major stationary air pollution sources had in general more respiratory symptoms than those from the distant school. However, in winter air pollution was generalized in this city and differences in health disappeared. PM10 levels were the most consistent factor related to pulmonary function according, to its change per 3-month period. PMID:21106102

    Deficits in arithmetic fact retrieval constitute the hallmark of children with mathematical learning difficulties (MLD). It remains, however, unclear which cognitive deficits underpin these difficulties in arithmetic fact retrieval. Many prior studies defined MLD by considering low achievement criteria and not by additionally taking the persistence of the MLD into account. Therefore, the present longitudinal study contrasted children with persistent MLD (MLD-p; mean age: 9 years 2 months) and typically developing (TD) children (mean age: 9 years 6 months) at three time points, to explore whether differences in arithmetic strategy development were associated with differences in numerical magnitude processing, working memory and phonological processing. Our longitudinal data revealed that children with MLD-p had persistent arithmetic fact retrieval deficits at each time point. Children with MLD-p showed persistent impairments in symbolic, but not in nonsymbolic, magnitude processing at each time point. The two groups differed in phonological processing, but not in working memory. Our data indicate that both domain-specific and domain-general cognitive abilities contribute to individual differences in children's arithmetic strategy development, and that the symbolic processing of numerical magnitudes might be a particular risk factor for children with MLD-p.

    This research examined whether peer relationships amongst ethnic minority status children reflect the social groups to which children belong and the degree to which they identify with these groups. A longitudinal study was conducted to investigate the influence of group identities (i.e., ethnic and national) on children's perceived peer acceptance and preference for same-ethnic friendships. Measures of ethnic and English identification, perceived peer acceptance, and friendship choice were administered to 207 south-Asian English children, aged between 5 and 11, at two time points 6 months apart. In line with predictions, longitudinal analysis showed that bicultural identification (i.e., higher ethnic and English identity) was related to higher perceived peer acceptance and less preference for same-ethnic friendships. Importantly, as hypothesized, this finding was limited to the older children with more advanced social-cognitive abilities. The results suggest that older children who adopted a bicultural identity were able to strategically 'flag' their multiple group identities, within their multicultural peer groups, to obtain acceptance amongst the maximum number of peers and show less preference for same-ethnic friendships. This study extends previous peer relations research, which has typically focused on individual social deficits or classroom norms, by showing that group identities influence peer relationships amongst ethnic minority status children.

    Recent models on parenting propose different roles for fathers and mothers in the development of child anxiety. Specifically, it is suggested that fathers' challenging parenting behavior, in which the child is playfully encouraged to push her limits, buffers against child anxiety. In this longitudinal study, we explored whether the effect of challenging parenting on children's social anxiety differed between fathers and mothers. Fathers and mothers from 94 families were separately observed with their two children (44 % girls), aged 2 and 4 years at Time 1, in three structured situations involving one puzzle task and two games. Overinvolved and challenging parenting behavior were coded. Child social anxiety was measured by observing the child's response to a stranger at Time 1, and half a year later at Time 2, and by parental ratings. In line with predictions, father's challenging parenting behavior predicted less subsequent observed social anxiety of the 4-year-old child. Mothers' challenging behavior, however, predicted more observed social anxiety of the 4-year-old. Parents' overinvolvement at Time 1 did not predict change in observed social anxiety of the 4-year-old child. For the 2-year-old child, maternal and paternal parenting behavior did not predict subsequent social anxiety, but early social anxiety marginally did. Parent-rated social anxiety was predicted by previous parental ratings of social anxiety, and not by parenting behavior. Challenging parenting behavior appears to have favorable effects on observed 4-year-old's social anxiety when displayed by the father. Challenging parenting behavior emerges as an important focus for future research and interventions.

    This paper presents the development of the Complementary Feeding Utility Index (CFUI), a composite index aimed to measure adherence to infant feeding guidelines. Through an axiomatic characterization this paper shows the advantages in using the CFUI are the following: it avoids the use of arbitrary cut-offs, and by converting observed diet preferences into utilities, summing the score is meaningful. In addition, as the CFUI is designed to be scored continuously, it allows the transition from intake of beneficial foods (in low quantities) and intake of detrimental foods (in high quantities) to be more subtle. The paper first describes the rationale being the development of the CFUI and then elaborates on the methodology used to develop the CFUI, including the process of selecting the components. The methodology is applied to data collected from the Avon Longitudinal Study of Parents and Children to show the advantages of the CFUI over traditional diet index approaches. Unlike traditional approaches, the distribution of the CFUI does not peak towards mean value but distributes evenly towards the tails of the distribution. PMID:24155886

    Background In experimental models of human and mouse malaria, sterilizing liver stage immunity that blocks progression of Plasmodium infection to the symptomatic blood stage can be readily demonstrated. However, it remains unclear whether individuals in malaria-endemic areas acquire such immunity. Methods In Mali, 251 healthy children and adults aged 4–25 years who were free of blood-stage Plasmodium infection by polymerase chain reaction (PCR) were enrolled in a longitudinal study just prior to an intense 6-month malaria season. Subsequent clinical malaria episodes were detected by weekly active surveillance and self-referral. Asymptomatic P. falciparum infections were detected by blood-smear microscopy and PCR analysis of dried blood spots that had been collected every 2 weeks for 7 months. Results As expected, the risk of clinical malaria decreased with increasing age (log-rank test, P = .0038). However, analysis of PCR data showed no age-related differences in P. falciparum infection risk (log-rank test, P = .37). Conclusions Despite years of exposure to intense P. falciparum transmission, there is no evidence of acquired, sterile immunity to P. falciparum infection in this population, even as clinical immunity to blood-stage malaria is clearly acquired. Understanding why repeated P. falciparum infections do not induce sterile protection may lead to insights for developing vaccines that target the liver stage in malaria-endemic populations.

    Introduction: Although preterm birth represents a risk factor for early mother-infant interactions, few studies have focused on toddlerhood, an important time for the development of symbolic play, autonomous skills, and child's socialization competences. Moreover, no study has looked at the effect of birth weight on mother-child interactions during this period. Expanding on the available literature on prematurity, the main objective of this study was to explore the quality of mother-toddler interactions during play, using a longitudinal research design, as well as taking into account the effect of birth weight. Method: 16 Extremely Low Birth Weight (ELBW), 24 Very Low Birth Weight (VLBW), 25 full-term children, and their mothers were recruited for the present study. Mother-child dyads were evaluated at 18, 24, and 30 months of child age. Ten minutes of mother-child play interaction were recorded and later coded according to the Emotional Availability Scales (EAS). Furthermore, the child's level of development was assessed through the Griffiths Scale, and its contribution controlled for. Results: ELBW dyads showed an overall lower level of emotional availability, compared to VLBW and full-term dyads, but no main effect of birth weight was found on specific EA dimensions. Moreover, a significant effect of child age emerged. Overall scores, and Child Responsiveness and Involvement scores improved over time, independently of birth weight. Lastly, a significant effect of the interaction between birth weight and child age was found. Between 18 and 30 months, the overall quality of the interaction significantly increased in ELBW and VLBW dyads. Additionally, between 18 and 30 months, VLBW children significantly improved their responsiveness, while their mothers' sensitivity, structuring, and non-intrusive behaviors improved. In contrast, no change emerged in full-term dyads, although scores were consistently higher than those of the other groups. Discussion: Birth weight

    Adiposity, low aerobic fitness and low levels of activity are all associated with clustered cardiovascular disease risk in children and their high prevalence represents a major public health concern. The aim of this study is to investigate the relationship of objectively measured physical activity (PA) with motor skills (agility and balance), aerobic fitness and %body fat in young children. This study is a cross-sectional and longitudinal analyses using mixed linear models. Longitudinal data were adjusted for baseline outcome parameters. In all, 217 healthy preschool children (age 4-6 years, 48% boys) participated in this study. PA (accelerometers), agility (obstacle course), dynamic balance (balance beam), aerobic fitness (20-m shuttle run) and %body fat (bioelectric impedance) at baseline and 9 months later. PA was positively associated with both motor skills and aerobic fitness at baseline as well as with their longitudinal changes. Specifically, only vigorous, but not total or moderate PA, was related to changes in aerobic fitness. Higher PA was associated with less %body fat at baseline, but not with its change. Conversely, baseline motor skills, aerobic fitness or %body fat were not related to changes in PA. In young children, baseline PA was associated with improvements in motor skills and in aerobic fitness, an important determinant of cardiovascular risk.

    A key prediction of cognitive theories of gender development concerns developmental trajectories in the relative strength or rigidity of gender typing. To examine these trajectories in early childhood, 229 children (African American, Mexican, Dominican) were followed annually from age 3 to 5 and gender-stereotypical appearance, dress-up play, toy play, and sex segregation were examined. High gender-typing was found across ethnic group, and most behaviors increased in rigidity, especially from age 3 to 4. In addressing controversy surrounding the stability and structure of gender-typing it was found that from year to year, most behaviors showed moderately stable individual differences. Behaviors were uncorrelated within age, but showed more concordance in change across time, suggesting that aspects of gender-typing are multidimensional but still show coherence. PMID:23432471

    Risk exposures and predictions of child development outcomes typically estimate the independent effects of individual exposures. As a rule though, children are not exposed piecemeal to individual or single risks but, rather, they are exposed to clusters of risk. Many of these clusters of risks are better thought of as comprising a developmental “circumstance” with a substantial duration, over which period, additional risk exposures also accumulate. In this paper we examined the distribution of 16 single risk exposures for low language ability using latent class analysis across a sample of approximately 4000 children from the Longitudinal Study of Australian Children. The best fitting model identified six distinct classes. 46% of children were in a Developmentally Enabled group, 20% were in a group typified as Working Poor families, 10% of children were in group typified as Overwhelmed group, 9% of children were in a group defined by Child Developmental Delay, 8% of children were in a group defined by Low Human Capital, and 7% of children were in a group defined by Resource Poor non-English Speaking background families. These groups had quantitatively and qualitatively distinct patterns of risk factors and showed different onward trajectories of receptive vocabulary. Our results demonstrate a range of multiple risk profiles in a population-representative sample of Australian children and highlight the mix of risk factors faced by children. Children with distinct patterns of risk factors have different onward trajectories of receptive vocabulary development. PMID:28114381

    To assess post-traumatic stress symptoms (PTSS) in mothers of children over 2 years of leukemia treatment, to identify possible early family and child predictors of this symptomatology and to indicate the temporal trajectory of PTSS. Participants were 76 Italian mothers (mean age = 37.30 years; SD = 6.07) of children receiving treatment for acute lymphoblastic (n = 69) or myeloid (n = 7) leukemia. Mothers had 12.05 years of education (SD = 3.87), and their incomes were average (52.1%), high (26%) and low (21.9%) for Italian norms, never in poverty. The pediatric patients with leukemia were equally distributed by gender with their mean age of 7.10 years (SD = 4.18). Post-traumatic stress symptoms were measured by a 17-item checklist. Scales assessing anxiety, depression, physical (Brief Symptom Inventory 18) and cognitive functioning (Problem Scale), and life evaluation were also used. There were five assessment points: 1 week (T1), 1 month (T2), 6 months (T3), 12 months (T4) and 24 months post-diagnosis (T5). The main results indicated moderate presence of clinical PTSS (≥9 symptoms: 24% at T2, 18% at T3, 16% at T4 and 19% at T5) that remained stable across time points, whereas Brief Symptom Inventory 18 Global score decreased and life evaluation improved. A series of hierarchical regression models identified cognitive functioning early after the diagnosis as the best predictive factor of PTSS across time points. Specific psychological interventions could be devised for mothers at risk for short and long-term PTSS just after the diagnosis. Copyright © 2012 John Wiley & Sons, Ltd.

    The Motorik-Modul (MoMo) Longitudinal Study aims to contribute to long-term improvement in the health of German children and adolescents by focusing on: (i) the development of physical fitness and physical activity (including period effects); (ii) the individual and physical/social environmental determinants of the development of physical fitness and physical activity; and (iii) the impact of physical fitness and physical activity on the development of physical and mental health. The MoMo Longitudinal Study began with a nationwide representative sample of 4529 children and adolescents who ranged in age from 4-17 years at the study baseline (2003-2006). The first survey wave of the MoMo Longitudinal Study was conducted between 2009 and 2012, with two subsequent survey waves to be conducted between 2014 and 2016 and 2018 and 2020, respectively. The MoMo Longitudinal Study includes a physical fitness test profile, a physical activity questionnaire, and subjective and objective measures of health from the German Health Interview and Examination Survey (KiGGS).

    Salmonella typhi and S. paratyphi are important causes of bacteremia in children, especially those from the developing world. There is a lack of standardized treatment protocols for such patients in the literature, and there are also reports of therapeutic failure related to resistance to commonly used antibiotics. We analyzed the epidemiological, clinical, and antimicrobiological sensitivity patterns of disease in patients diagnosed with blood culture-positive typhoid fever over a 6-month period in a tertiary-care pediatric hospital in western India. Data were retrospectively analyzed for all patients with Salmonella isolates on blood culture between January 1 and June 30, 2011 at the Synergy Neonatal and Pediatric Hospital. Susceptibility of isolates to antimicrobials and minimum inhibitory concentrations were determined. Demographic data, symptoms and signs, basic laboratory results, treatment courses, and clinical outcomes were collected from clinical charts. All of the 61 isolates of S. typhi were sensitive to cefepime (fourth-generation cephalosporin), 96% to third-generation cephalosporins, and 95% to quinolones. There was intermediate sensitivity to ampicillin (92%) and chloramphenicol (80%). Notably, azithromycin resistance was observed in 63% of isolates. All patients ultimately made full recoveries. There is an urgent need for large scale, community-based clinical trials to evaluate the effectiveness of different antibiotics in enteric fever. Our antimicrobial susceptibility data suggest that quinolones and third-generation cephalosporins should be used as first-line antimicrobials in enteric fever. Although fourth-generation cephalosporins are useful, we feel their use should be restricted to complicated or resistant cases.

    This two-cohort longitudinal study on the development of the semantic grouping strategy had three goals. First, the authors examined if 6-7-year-olds are nonstrategic before becoming strategic after prompting at 8-9 years of age, and if 8-9-year-olds are prompted strategic before spontaneous strategy use at 10-11 years of age. Children 6-7 and 8-9 years old performed two sort-recall tasks (one without and one with a grouping prompt) at two time points separated 1.5 years from each other. Second, the authors investigated whether short-term or working memory capacity at time point 1 predicted recall in children who did or did not use the semantic grouping strategy 1.5 years later. Third, the authors investigated whether prompted strategic children and children who used the strategy spontaneously differed in strategy transfer to a new task. Developmental results confirmed previous cross-sectional results, but in a longitudinal two-cohort study 6-7-year-olds were nonstrategic, and became prompted strategic around 8-9 years of age, followed by spontaneous strategy use at age 10-11 years. The authors found that memory capacity was not predictive of later use of the strategy. New findings were that prompted strategic children were as equally able as spontaneously strategic children to transfer the strategy to a new task, albeit with smaller recall benefits.

    Objective The objectives of this review are to highlight the impact of the first decade of high-risk (HR) infant sibling work in autism spectrum disorder (ASD) and to identify potential areas of translational focus for the next decade of research. Method A group of clinicians and researchers in ASD working both inside and outside of the HR design met on a regular basis to review the infant sibling research, and came to an agreement on areas that had changed clinical practice and areas that had the potential to change practice with further research. The group then outlined several methodological and translational challenges that must be addressed in the next decade of research if the field is to reach its potential. Results The review concluded that the HR design has yielded an understanding that ASD often, but not always, begins to emerge between 6 and 18 months, with early signs affecting social communication. Research using the HR design has also allowed a better understanding of the sibling recurrence risk (between 10% and 20%). Emerging areas of interest include the developmental trajectories of social communications skills in the early years, the expression of a milder phenotype in siblings not affected with ASD, and the possibility that early intervention with infant siblings may improve outcomes for those with ASD. Important challenges for the future include linking screening to intervention, collecting large sample sizes while ensuring cross-site reliability, and building in capacity for replication. Conclusion Although there are significant methodological and translational challenges for high-risk infant sibling research, the potential of this design to improve long-term outcomes of all children with ASD is substantial.
