Craniofacial morphology, dental occlusion, tooth eruption, and dental maturity in boys of short stature with or without growth hormone deficiency.

PubMed

Kjellberg, H; Beiring, M; Albertsson Wikland, K

2000-10-01

The aim of this project was to study the craniofacial morphology, dental occlusion, dental maturation and tooth eruption in short-statured boys with growth hormone secretion ranging from low to high. The measurements from lateral and posteroanterior cephalograms, orthopantomograms and plaster models were used. Almost all linear measurements of the facial structures were significantly smaller. A disproportionate growth in the cranial base structures as well as in the jaws resulted in facial retrognathia, a proportionately smaller posterior than anterior facial height, and a steep vertical inclination of the mandible. Dental crowding was more common and the overbite was small. Dental maturity and tooth eruption were delayed 1.2 and 1.3 yr, respectively. No significant differences between the idiopathic short-statured and the growth hormone-deficient group in any of the above-mentioned variables were found. It can be concluded that although most of the cephalometric variables measured differed significantly from the average, the facial appearance of the boys is not conspicuous and is of minor clinical importance. However, the short-statured boys might be in greater need of orthodontic treatment due to the higher percentage of dental crowding.

An exploration of gender participation patterns in science competitions

NASA Astrophysics Data System (ADS)

Arámbula Greenfield, Teresa

This study investigated participation in a state-level science competition over most of its 35-year history. Issues examined included whether different gender patterns occurred with respect to entry rate, project topic (life science, physical science, earth science, and math), and project type (research or display). The study also examined to what extent the identified patterns reflected or contradicted nationwide patterns of girls' academic performance in science over roughly the same time period. It was found that although girls initially participated in the fair less frequently than boys, for the past 20 years their participation rate has been greater than that of boys. Examination of topic preferences over the years indicates that both girls and boys have traditionally favored life science; however, boys have been and continue to be more likely to prepare physical, earth, and math/computer science projects than girls. Another gender difference is that girls are generally less likely than boys to prepare projects based on experimental research as opposed to library research. The study provides some suggestions for teachers and teacher educators for addressing these disparities.Received: 4 February 1994; Revised: 12 January 1995;

The Yucca Mountain Site Characterization Project (YMP) sponsors a variety of classroom-oriented projects and activities for teachers who request them. Also available, though, are extra-curricular programs. One notably successful program is a workshop designed to award girl and boy scouts with geology and atomic energy merit badges. There was a tremendous response to this workshop--it attracted 450 requests within the first week of its announcement. Since October 1991, the YMP has sponsored five such girl scout workshops and four boy scout workshops, attended by a total of 400 scouts. These workshops demonstrate that highly technical subjects can be taught simplymore » through hands-on activities. The idea behind them is not to teach scouts what to think but, rather, how to think. For adults meanwhile, the YMP offers a monthly lecture series, with each lecture averaging 45 minutes in length with 35 people in attendance. These lectures center on such subjects as volcanoes, earthquakes and hydrology. They are usually delivered by YMP technical staff members, who have learned that complex technical issues are best addressed in a small-group format.« less

Empathy in boys with gender identity disorder: a comparison to externalizing clinical control boys and community control boys and girls.

PubMed

Owen-Anderson, Allison F H; Jenkins, Jennifer M; Bradley, Susan J; Zucker, Kenneth J

2008-03-01

The construct of empathy was examined in 20 boys with gender identity disorder (GID), 20 clinical control boys with externalizing disorders (ECC), 20 community control boys (NCB), and 20 community control girls (NCG). The mean age of the children was 6.86 years (range = 4-8 years). It was hypothesized that boys with GID would show similar levels of empathy to those shown by NC girls and higher levels of empathy than the NC and ECC boys. Three measures of empathy were administered: a maternal-report questionnaire, a self-report questionnaire, and an in vivo evaluation in which children's reactions to pain simulations to two adult actors (mother, experimenter) were coded for empathy levels. On the maternal report and in-vivo measures, the NC girls had significantly higher empathy levels than the NC boys, but not on the self-report measure. By maternal report, the NC girls were rated as significantly more empathic than were the GID boys, with a "large" effect size. There were no significant differences between the GID boys and the NC girls on the self-report and in-vivo measures and the effect size differences were "small." No significant differences were observed between the GID and NC boys; however, there were "medium" and "small" effect size differences with boys with GID showing more empathy on the in-vivo and self-report measures, respectively. On the maternal-report measure, the GID boys were rated as significantly more empathic than the ECC boys and there was a trend for the GID boys to show greater levels of empathy than the ECC boys on both the self-report and in-vivo measures. The effect size differences on all three empathy measures were "medium" to "large," with GID boys showing more empathy than ECC boys. Empathy as a dispositional characteristic in the genesis and perpetuation of GID in boys is discussed.

Of considerable interest from both a physical and practical viewpoint is the coupling of electromagnetic energy from a nuclear explosion into various electrical systems in the vicinity of the burst. A series of electromagnetic measurements were made on Shots Little Feller I, Little Feller II, and Johnie Boy. It is clear from the records that radiation shielding must be given closer consideration in future tests. Due to equipment failure and radiation inactivation, only the Johnie Boy dynamic current measurement and the passive peak current indicators on all three events are interpretable.

2009-01-01

The study evaluated the growth status and secular change in body size of indigenous Tarahumara children in northern Mexico. Heights and weights of Tarahumara children 6-14 years were measured in 1990 (n = 601) and 2007 (n = 583); the BMI was calculated. International criteria defined weight status while United States reference data defined stunting. Estimated secular gains in height from 1990 to 2007 were greatest in 6-7 year-old boys and declined with age to a small, non-significant secular decline in boys 12-14 years. Among girls secular gains in height were similar at 6-7 and 8-9 years, largest at 10-11 years and small and non-significant at 12-14 years. Secular gains in weight were similar among 6-7 and 8-9 year-old boys and girls, were greater in girls than in boys at 10-11 years and showed a small, non-significant secular decline in boys and girls 12-14 years. Secular change in the BMI paralleled those for weight. The prevalence of stunting declined from 1990 to 2007 in both sexes and all age groups except 12-14 year youth. Overweight was more prevalent in girls than boys in both years and increased from 4% to 7% in boys and 9% to 13% in girls. Obesity was not common among boys and girls in each age group and in both years. Stunting and overweight/obesity were not related in either 1990 or 2007. Positive secular changes in growth status have occurred in Tarahumara children 6-11 years in contrast to negligible changes among children 12-14 years. The results suggest recent improvements in health and nutrition sufficient to support a positive secular trend in younger children.

Ex-Premature Infant Boys with Hypospadias are Similar in Size to Age-Matched, Ex-Premature Infant Boys Without Hypospadias

Hsieh, Michael H.; Alonzo, David G.; Gonzales, Edmond T.; Jones, Eric A.; Cisek, Lars J.; Roth, David R.

2010-01-01

OBJECTIVE Studies have postulated that hypospadias, prematurity, and low birth weight are linked by defects in androgen signaling. To determine whether premature, hypospadiac boys are small and remain so, we compared their size at birth and at hypospadias repair to premature boys who underwent post-neonatal circumcision. METHODS We identified premature boys admitted to Texas Children's Hospital who underwent either hypospadias repair or circumcision after 4 months of age. Age, weight, and height at birth and surgery were recorded. RESULTS Fifty-four boys had hypospadias and 34 did not. For hypospadiac boys, the mean birth weight and age, height, and weight at surgery were lower than for boys without hypospadias. More importantly, length-for-age and weight-for-age percentiles were also lower for hypospadiac boys. When subset analysis was performed on boys younger than 2 years at surgery, however, there were no significant differences in height or weight between hypospadiac and nonhypospadiac boys. CONCLUSION Our series suggests that premature, hypospadiac boys are born smaller than age-matched, non-hypospadiac controls. However, there were no age-corrected size differences between hypospadiac and non-hypospadiac boys at surgery. This implies that hypospadiac boys exhibit postneonatal ‘rebound’ growth. Global growth deficits, if any, do not persist in hypospadiac boys. PMID:20833109

Feedback associated with expectation for larger-reward improves visuospatial working memory performances in children with ADHD.

Hammer, Rubi; Tennekoon, Michael; Cooke, Gillian E; Gayda, Jessica; Stein, Mark A; Booth, James R

2015-08-01

We tested the interactive effect of feedback and reward on visuospatial working memory in children with ADHD. Seventeen boys with ADHD and 17 Normal Control (NC) boys underwent functional magnetic resonance imaging (fMRI) while performing four visuospatial 2-back tasks that required monitoring the spatial location of letters presented on a display. Tasks varied in reward size (large; small) and feedback availability (no-feedback; feedback). While the performance of NC boys was high in all conditions, boys with ADHD exhibited higher performance (similar to those of NC boys) only when they received feedback associated with large-reward. Performance pattern in both groups was mirrored by neural activity in an executive function neural network comprised of few distinct frontal brain regions. Specifically, neural activity in the left and right middle frontal gyri of boys with ADHD became normal-like only when feedback was available, mainly when feedback was associated with large-reward. When feedback was associated with small-reward, or when large-reward was expected but feedback was not available, boys with ADHD exhibited altered neural activity in the medial orbitofrontal cortex and anterior insula. This suggests that contextual support normalizes activity in executive brain regions in children with ADHD, which results in improved working memory. Copyright © 2015 The Authors.

Students' attitudes towards mathematics in single-sex and coeducational schools

NASA Astrophysics Data System (ADS)

Norton, Stephen J.; Rennie, Léonie J.

1998-04-01

This paper examines students' attitudes towards mathematics at the secondary school level. Using five of the Fennema-Sherman scales, the attitudes of boys and girls in Grades 8 to 12 in four schools were compared: a single-sex boys' and a single-sex girls' private school, and a state and a private coeducational school. Multivariate analysis of variance was used to guide an exploration of how students' attitudes varied according to grade, sex and educational setting. There were no differences between students in the two coeducational schools. In general, students' attitudes were found to be less positive in more senior grades; and overall, boys had more positive attitudes than girls. There were clear differences between boys and girls on the Mathematics as a Male Domain scale, with girls being less stereotyped in their perceptions than boys. Except for this scale, effects related to the sex of the student were small, and effects relating to grade level and school type on all variables were also small. Implications are drawn for future research in this area.

Recently, we examined a 2-year-old boy with the association of microcephaly and significant pedal edema that extended to the distal parts of the legs. Prometaphase chromosome studies showed a small terminal deletion in the long arm of chromosome 13 of band 13q34, karyotype 46,XY,del(13)(q34{yields}qter). The present finding of a small terminal 13q34 deletion in this young boy with microcephaly/lymphedema is a first indication that the lymphedema/microcephaly association can be due to a small terminal 13q deletion. 2 refs.

Girls' and boys' experience with teen sexting in early and late adolescence.

PubMed

Ševčíková, Anna

2016-08-01

This study explored the extent to which sexting represents a problematic behavior in early and late adolescence. Using data from the EU Kids Online II project (17,016 participants aged 11-16 from 25 European countries, 49.7% boys), multilevel logistic regression analyses were conducted separately for four groups: younger girls, older girls, younger boys, and older boys. Irrespective of age and gender, sexting was associated with emotional problems and alcohol use. Its effect decreased in older adolescents, except for emotional difficulties, which remained relatively high in older boys. Vaginal sex was associated with sexting in both younger and older boys while, in girls, the association was observed only in the older group. Younger boys with higher self-efficacy were more likely to send sexts than those with lower self-efficacy. Although sexting is associated with psychological challenges and other types of risk behavior, sexting in some younger boys may not necessarily represent problematic behavior.

Pekkarinen, H; Litmanen, H; Mahlamäki, S

1989-01-01

In order to evaluate physiological characteristics in young male ballet dancers, 27 boys (aged 9 to 16 years) who participated in a boys' dance course during the Kuopio Dance and Music Festival in June 1988 were studied. In general, the boys had started dancing at the age of 8.6 years and had been training for 4.1 years. They had, on average, three dancing sessions per week and the mean time spent on dancing was four hours per week. In the study, some anthropometric measurements were taken, the maximal oxygen uptake (VO2 max) was measured by a cycle ergometer test and the explosive strength and the mechanical power of lower extremities were evaluated by a jumping test. The results indicate that boys who train in ballet are in general moderately lean, have relatively small body size and a high degree of flexibility. The younger boys especially have only moderate aerobic power, but both explosive strength and mechanical power in leg muscles are good in ballet trained boys. PMID:2630002

2015-05-01

An 8-year boy was admitted to the ER of one of Warsaw's pediatric hospitals with a history of having bloody vomiting the day before. During admission the boy collapsed and lost consciousness. CPR was unsuccessful. On medico-legal autopsy, two foreign objects (small magnetic spheres--0.5 cm in diameter) were found in two different places in the small and large intestines and were notably attracted magnetically one to another. A loop of approximately 1-m length with features of small intestinal hemorrhagic necrosis and small intestinal mechanical obstruction was found. The cause of death was intestinal volvulus and small intestinal mechanical obstruction caused by ingestion of foreign objects (two neodymium magnets). Most likely these small magnetic spheres were part of a popular toy, the safety of which, lately, has been widely discussed. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Group therapy with sexually abused boys: leadership, projective identification, and countertransference issues.

PubMed

Schacht, A J; Kerlinsky, D; Carlson, C

1990-10-01

Group therapy is an essential component of the treatment of sexually abused children. Since the painful effects associated with the abuse are often dissociated or acted out, the group leaders learn of the affective experience of the abuse through the process of projective identification. The leaders must be aware of this process, set limits on the abusive acting out in the group, and help moderate, label, and empathize with the affect. It is through this difficult process that the children have a chance to reintegrate and work through their abuse experiences so they no longer feel compelled to act them out through repetitive abusive relationships. Specific leadership, countertransference, and projective identification issues in group therapy with sexually abused boys are discussed.

Equity, empowerment and different ways of knowing

NASA Astrophysics Data System (ADS)

Boaler, Jo

1997-11-01

This paper considers the experiences of two sets of students who attended schools that taught mathematics in completely different ways. One of the schools used a traditional, textbook approach, and the other used an open, project-based approach. The latter approach produced equity between girls and boys whereas the textbook approach prompted many of the girls to under achieve. This paper will consider the experiences of girls and boys who followed the project-based approach, reflect upon the sources of equity within this approach and relate the differences between the two approaches to Gilligan's notions of "separate" and "connected" knowing.

Psychosocial correlates of police-registered youth crime. A Finnish population-based study.

PubMed

Elonheimo, Henrik; Sourander, Andre; Niemelä, Solja; Nuutila, Ari-Matti; Helenius, Hans; Sillanmäki, Lauri; Ristkari, Terja; Parkkola, Kai

2009-01-01

This study is focused on psychosocial correlates of youth crime in a sample of 2330 Finnish boys born in 1981. Two kinds of data were combined: questionnaires completed by the boys at call-up in 1999 and crime registered in the Finnish National Police Register between 1998 and 2001. One-fifth of the boys were registered to offending during the 4-year period in late adolescence; 14% were registered for one or two offences, 4% for three to five offences, and 3% for more than five offences. Crime accumulated heavily in those with more than five offences, as they accounted for 68% of all crime. Independent correlates of crime were living in a small community, parents' low educational level and divorce, having a regular relationship, self-reported delinquency, daily smoking, and weekly drunkenness, whereas anxious-depressiveness was reversely associated with crime. Most psychosocial problems covaried linearly with offending frequency, being particularly manifested by multiple recidivists. However, recidivists had very rarely used mental health services. The results indicate that offending and various psychosocial problems accumulate in a small minority of boys not reached by mental health services.

Mental and somatic health in a non-clinical sample 10 years after a diagnosis of encopresis.

PubMed

Hultén, Ib; Jonsson, Jakob; Jonsson, Carl-Otto

2005-12-01

The aim of this study was to assess the relation between the diagnosis of encopresis at 8 and 10 years of age, and mental and somatic health 10 years later. The importance of type of encopresis (primary or secondary) at 8 years was also studied. Subjects were a non-clinical encopretic sample (N=73) and control subjects (N=75) [2]. Seven assessment variables from conscription surveys provided information about mental and somatic health status at 18 years of age. Former encopretics (n=66) did not differ significantly from the controls (n=67) at 18 years of age, although there were consistent, small negative differences. The boys who at 10 years of age had still been encopretic did not differ significantly at 18 years of age from the boys who at 10 years had recovered from encopresis, and the signs indicating the small differences varied. For former primary and secondary encopretic boys, there were two significant differences, the men in the secondary group being more often exempted from conscription than the primary group and the control cases. The results indicate that boys with non-clinical encopresis show only small, if any, mental and somatic disturbances at the beginning of adulthood. Comprehensive investigations of encopretic patients are recommended as important clinical problems, in addition to encopresis, might be present.

Initial sociometric impressions of attention-deficit hyperactivity disorder and comparison boys: predictions from social behaviors and from nonbehavioral variables.

PubMed

Erhardt, Drew; Hinshaw, Stephen P

1994-08-01

This study systematically compared the influence of naturalistic social behaviors and nonbehavioral variables on the development of peer status in 49 previously unfamiliar boys, aged 6-12 years, who attended a summer research program. Twenty-five boys with attention-deficit hyperactivity disorder (ADHD) and 24 comparison boys participated. Physical attractiveness, motor competence, intelligence, and academic achievement constituted the nonbehavioral variables; social behaviors included noncompliance, aggression, prosocial actions, and isolation, measured by live observations of classroom and playground interactions. As early as the first day of interaction, ADHD and comparison boys displayed clear differences in social behaviors, and the ADHD youngsters were overwhelmingly rejected. Whereas prosocial behavior independently predicted friendship ratings during the first week, the magnitude of prediction was small. In contrast, the boys' aggression (or noncompliance) strongly predicted negative nominations, even with nonbehavioral factors, group status (ADHD versus comparison), and other social behaviors controlled statistically. Implications for understanding and remediating negative peer reputations are discussed.

Letter-Sound Knowledge: Exploring Gender Differences in Children When They Start School Regarding Knowledge of Large Letters, Small Letters, Sound Large Letters, and Sound Small Letters

PubMed Central

Sigmundsson, Hermundur; Eriksen, Adrian D.; Ofteland, Greta Storm; Haga, Monika

2017-01-01

This study explored whether there is a gender difference in letter-sound knowledge when children start at school. 485 children aged 5–6 years completed assessment of letter-sound knowledge, i.e., large letters; sound of large letters; small letters; sound of small letters. The findings indicate a significant difference between girls and boys in all four factors tested in this study in favor of the girls. There are still no clear explanations to the basis of a presumed gender difference in letter-sound knowledge. That the findings have origin in neuro-biological factors cannot be excluded, however, the fact that girls probably have been exposed to more language experience/stimulation compared to boys, lends support to explanations derived from environmental aspects.

Childhood obesity is a global problem, sociodemographic and cultural factors influence its presence. An analysis of disparities in the prevalence of childhood obesity in Peru was made by sex and region in 2015. Analysis of the information reported by the Sistema de Información del Estado Nutricional of the number of obesity cases in 2,336,791 children under five years, evaluated in public health facilities during 2015. The distribution of obesity cases was analyzed by sex and region of residence, also a spatial projection of the regional prevalence of obesity and the prevalence differences between men and women was performed. Data from 2,336,791 children under five was analyzed. An obesity prevalence of 1.52% (girls: 1.3% and boys: 1.7%) was found; the highest prevalence were observed in urban areas (girls: 1.5% and boys: 1.9%) and on the Costa (girls: 1.9% and boys: 2.5%). Highest prevalence of obesity were in Tacna (girls: 3.2% y boys: 3.9%), Moquegua (girls: 2.4% y boys: 3.1%) and Callao (girls: 2.3% y boys: 2.8%). Childhood obesity predominates on the coast and in urban areas of Peru particularly among boys. The regions of higher prevalence of obesity were Tacna Moquegua and Callao.

To identify the genetic cause for a 11-year-old Chinese boy with Meier-Gorlin syndrome (MGS). Chromosomal microarray analysis (CMA) was used to detect potential variations, while whole exome sequencing (WES) was used to identify sequence variants. Sanger sequencing was used to confirm the suspected variants. The boy has featured short stature, microtia, small patella, slender body build, craniofacial anomalies, and small testes with normal gonadotropin. A complete uniparental disomy of chromosome 16 was revealed by CMA. WES has identified a novel homozygous mutation c.67A>G (p.Lys23Glu) in ORC6 gene mapped to chromosome 16. As predicted by Alamut functional software, the mutation may affect the function of structural domain of the ORC6 protein. The patient is probably the first diagnosed MGS case in China, who carried a novel homozygous mutation of the ORC6 gene and uniparental disomy of chromosome 16. The effect of this novel mutation on the growth and development needs to be further investigated.

PE is not for me: when boys' masculinities are threatened.

PubMed

Tischler, Amy; McCaughtry, Nate

2011-03-01

This study used hegemonic masculinity theory to examine the intersection of masculinities and school physical education from the perspectives of boys who embodied masculinities that were marginalized. Over a 13-week period using present-focused, student-centered, qualitative methodological approaches, we observed, interviewed, and worked in small groups with 5 middle school boys from two schools. We identified three significant themes that merge the stories and experiences of masculinity hierarchies in sport-based physical education. First, we found that four social practices (content, pedagogies, teacher-student relationships, and peer cultures) in these physical education settings privileged some masculinities over others. Second, we examined the role that embodiment played, both in how the boys wore their oppression and in how their bodies resisted marginalizing situations. Third, we describe the contrasts these boys drew between physical activities experienced in sport-based physical education and physical activity experiences in other areas of their lives. We used Connell and Messerschmidt's (2005) reconceptualization of the theory of hegemonic masculinity for understanding how competitive sport-based physical education functioned to oppress boys with masculinities that were deemed abnormal. Additionally, we introduce feminist poststructuralism as a possible theoretical lens for interpreting boys' bodies as also being active agents in social practices rather than being only passive objects who are oppressed and dominated.

Three Wishes and Psychological Functioning in Boys with Duchenne Muscular Dystrophy

2007-01-01

This study examined Three Wishes (a projective technique commonly used with children) in boys with Duchenne muscular dystrophy (DMD), a fatal, progressive illness (n = 74). A reliable and parsimonious scoring system was developed to code wish type. Probands’ responses were compared with unaffected siblings (n = 32) and a male comparison group (n = 43). Contrary to what was expected, the DMD group did not make significantly more health-related wishes than their siblings or the comparison group. Further, no association between health-related wishes and problem behaviors was observed in the DMD group. These findings indicate that, despite increased stressors, boys with DMD present wishes similar to those of their healthy peers. PMID:12692454

2016-10-01

We studied the association of dental maturity with body mass index (BMI), energy intake, and macronutrient intake. A randomly selected subset (n = 148) of the Special Turku Coronary Risk Factor Intervention Project (STRIP) was invited to an oral follow-up study, and the 6- and 12-yr-examination data (n = 111, 60 boys) were used. Food records for four consecutive days and BMI values were extracted from the databank of the main STRIP project. The developmental stage of seven permanent mandibular teeth was assessed using panoramic radiographs. The resulting maturity scores were converted to dental age estimates. Three dental-maturity groups (delayed, average, and advanced) and two BMI groups [normal BMI (≤mean+1SD) and high BMI (>mean+1SD)] were formed. The dental age was higher than the chronological age by 0.6-0.8 yr. Maturity scores for girls were statistically significantly higher than for boys. The distribution of girls into dental-maturity groups at age 12 yr was different from that of the boys and there were more boys than girls among the high-BMI group. Children of the advanced dental-maturity group had a statistically significantly higher energy intake than children in the other groups. We conclude that advanced dental maturity is associated with higher energy intake. © 2016 Eur J Oral Sci.

Understanding the Influence of Race/Ethnicity, Gender, and Class on Inequalities in Academic and Non-Academic Outcomes among Eighth-Grade Students: Findings from an Intersectionality Approach

2015-01-01

Socioeconomic, racial/ethnic, and gender inequalities in academic achievement have been widely reported in the US, but how these three axes of inequality intersect to determine academic and non-academic outcomes among school-aged children is not well understood. Using data from the US Early Childhood Longitudinal Study—Kindergarten (ECLS-K; N = 10,115), we apply an intersectionality approach to examine inequalities across eighth-grade outcomes at the intersection of six racial/ethnic and gender groups (Latino girls and boys, Black girls and boys, and White girls and boys) and four classes of socioeconomic advantage/disadvantage. Results of mixture models show large inequalities in socioemotional outcomes (internalizing behavior, locus of control, and self-concept) across classes of advantage/disadvantage. Within classes of advantage/disadvantage, racial/ethnic and gender inequalities are predominantly found in the most advantaged class, where Black boys and girls, and Latina girls, underperform White boys in academic assessments, but not in socioemotional outcomes. In these latter outcomes, Black boys and girls perform better than White boys. Latino boys show small differences as compared to White boys, mainly in science assessments. The contrasting outcomes between racial/ethnic and gender minorities in self-assessment and socioemotional outcomes, as compared to standardized assessments, highlight the detrimental effect that intersecting racial/ethnic and gender discrimination have in patterning academic outcomes that predict success in adult life. Interventions to eliminate achievement gaps cannot fully succeed as long as social stratification caused by gender and racial discrimination is not addressed. PMID:26505623

2010-04-01

We investigated body image dissatisfaction and bingeing/purging characteristics of bulimia nervosa (BN) in the ongoing prospective follow-up of the Multimodal Treatment Study of Children with attention-deficit/hyperactivity disorder (ADHD). Participants were 337 boys and 95 girls with ADHD and 211 boys and 53 girls forming a local normative comparison group (LNCG), reassessed in midadolescence (mean age, 16.4), 8 years after original recruitment. Youth with childhood ADHD showed more BN symptoms in midadolescence than did LNCG youth, and girls demonstrated more BN symptoms than did boys, with effect sizes between small and medium. Childhood impulsivity, as opposed to hyperactivity or inattention, best predicted adolescent BN symptoms, particularly for girls. Among youth with ADHD, treatment received during the follow-up period was not associated with BN pathology. Both boys and girls with ADHD may be at risk for BN symptoms in adolescence because of the impulsivity central to both disorders.

2010-10-01

Developmental trajectories in delinquency through adolescence were studied along with family and peer relationship problems. Drawing from eight waves of data over seven years, we conducted trajectory analyses with a sample of 746 students (402 girls; 344 boys). Analyzing girls and boys together, a five-class model emerged: 60% of the adolescents rarely reported delinquency; 27.7% reported low initial levels with moderate levels of delinquency over time; 6% in the late onset group reported initially low and rising levels of delinquency; 5% in the early onset group reported moderate initial levels which increased and then decreased in later adolescence. A small group of only boys (1.3%) labeled chronic reported high initial levels of delinquency that increased over time. Group comparisons revealed problems in internalizing, parent and peer relationship problems. The findings provide direction for early identification and interventions to curtail the development of delinquency.

Targeted weight-bearing activities during the pre-pubertal years can improve cortical bone mass, structure and distribution, but less is known about the influence of habitual physical activity (PA) and fitness. This study examined the effects of contrasting habitual PA and fitness levels on cortical bone density, geometry and mass distribution in pre-pubertal children. Boys (n = 241) and girls (n = 245) aged 7-9 years had a pQCT scan to measure tibial mid-shaft total, cortical and medullary area, cortical thickness, density, polar strength strain index (SSIpolar) and the mass/density distribution through the bone cortex (radial distribution divided into endo-, mid- and pericortical regions) and around the centre of mass (polar distribution). Four contrasting PA and fitness groups (inactive-unfit, inactive-fit, active-unfit, active-fit) were generated based on daily step counts (pedometer, 7-days) and fitness levels (20-m shuttle test and vertical jump) for boys and girls separately. Active-fit boys had 7.3-7.7 % greater cortical area and thickness compared to inactive-unfit boys (P < 0.05), which was largely due to a 6.4-7.8 % (P < 0.05) greater cortical mass in the posterior-lateral, medial and posterior-medial 66 % tibial regions. Cortical area was not significantly different across PA-fitness categories in girls, but active-fit girls had 6.1 % (P < 0.05) greater SSIpolar compared to inactive-fit girls, which was likely due to their 6.7 % (P < 0.05) greater total bone area. There was also a small region-specific cortical mass benefit in the posterior-medial 66 % tibia cortex in active-fit girls. Higher levels of habitual PA-fitness were associated with small regional-specific gains in 66 % tibial cortical bone mass in pre-pubertal children, particularly boys.

Gilbert, Lucia Albino; Bravo, Melinda J.; Kearney, Lisa K.

The authors report on a project conducted in 2 consecutive years at the same public middle school. The project was designed to challenge the view that technology is a male domain. In the main study, teachers partnered with researchers to implement an innovative educational intervention focused on disrupting gender stereotype - producing dynamics among students' peer groups. Participants were 151 seventh grade students and their teachers. The intervention was successful in bringing about hypothesized changes in girls' relation to technology. Girls in the treatment group reported greater interest in future computer and technology involvement than girls in the control group. In addition, girls in the intervention reported less endorsement of boys' computer expertise than girls in the control group. Although the intervention was designed for girls, overall, boys' reactions were quite positive.

Youth development programs, such as the Boy Scouts of America, aim to develop positive attributes in youth (e.g., character virtues, prosocial behaviors, and positive civic actions), which are necessary for individuals and societies to flourish. However, few developmental studies have focused on how specific positive attributes develop through participation in programs such as the Boy Scouts of America. As part of the Character and Merit Project, this article examined the developmental trajectories of character and other positive attributes, which are of focal concern of the Boy Scouts of America and the developmental literature. Data were collected from 1398 Scouts (M = 8.59 years, SD = 1.29 years, Range 6.17-11.92 years) and 325 non-Scout boys (M = 9.06 years, SD = 1.43 years, Range 6.20-11.81 years) over five waves of testing across a two-and-half-year period. Latent growth-curve analyses of self-report survey data examined the developmental trajectories of the attributes. Older youth rated themselves lower than younger participants on helpfulness, reverence, thriftiness, and school performance. However, all youth had moderately high self-ratings on all the attributes. Across waves, Scouts' self-ratings increased significantly for cheerfulness, helpfulness, kindness, obedience, trustworthiness, and hopeful future expectations. Non-Scout boys' self-ratings showed no significant change for any attributes except for a significant decrease in religious reverence among non-Scout boys from religious institutions. We discuss implications for positive youth development and for the role of the Boy Scouts of America programming in character development.

The relation of severe malnutrition in infancy to the intelligence of school children with differing life histories.

Richardson, S A

1976-01-01

The IQ's of Jamaican boys aged 6-10 were associated significantly with the presence or absence of severe malnutrition in infancy, with height at time of IQ testing, and with a measure of the boys' social background. A multiple correlation coefficient of 0.674 was obtained between IQ and the three factors. Social background contributed 0.294 of the variance, height 0.112, and severe malnutrition 0.049. The two extreme groups of boys, i.e., those malnourished, small at follow-up, and with unfavorable social backgrounds and those not malnourished, tall at follow-up, and with favorable social backgrounds had average IQ's of 49.4 and 74.9, respectively (from Table 5). Only two of the boys in the most advantaged group had IQ scores that overlapped with the most disadvantaged group. Boys with severe malnutrition in infancy, but who are tall at follow-up and have a favorable social background have an average IQ 11 points higher than boys who did not experience severe malnutrition, but who are short at follow-up and have a unfavorable social background. The difference in IQ between boys who did and did not experience severe malnutrition in infancy varies under different conditions of height and social background when those are held constant for both groups. Under the most favorable conditions of being tall and having an advantageous social history the average IQ of the malnourtished boys in only 2 points lower than those not malnourished. Unde the most unfavorable conditions of short stature and a disadvantageous social background the IQ of the malnourished boys is 9 points lower than those not malnourished (Table 6 and Fig. 1).

To examine sedentary behaviours (including television viewing, playing computer games and computer use), diet, exercise and fitness in relation to overweight/obesity in Australian adolescents. Questionnaires elicited food frequency data, time spent in TV-viewing, using computers, other sedentary occupations and physical activity recall. Weight, height and fitness (laps completed in the Leger test) were measured. Among 281 boys and 321 girls, mean age 12 years (SD 0.9), 56 boys (20.0%) and 70 girls (23.3%) were overweight/obese. Greater fitness was associated with decreased risk of overweight/obesity in boys (Odds ratio [OR] 0.74; 95% CI 0.55, 0.99) and girls (OR 0.93; 95% CI 0.91, 0.99). TV-viewing predicted increased risk in boys (OR 1.04; 95% CI 1.01, 1.06) and decreased risk in girls (OR 0.99; 95% CI 0.96, 0.99). Computer use, video games, and other sedentary behaviours were not significantly related to risk of overweight/obesity. Vegetable intake was associated with lower risk in boys (OR 0.98; 95% CI 0.97, 0.99); greater risk was associated with lower fat intake in boys and girls, lower consumption of energy-dense snacks in boys (OR 0.74; 95% CI 0.62, 0.88) and greater intake of vegetables in girls (OR 1.02; 95% CI 1.00, 1.03), suggesting dieting or knowledge of favourable dietary choices in overweight/obese children. Among these adolescents, fitness was negatively related to risk for overweight/obesity in boys and girls. TV-viewing was a positive predictor in boys and a negative predictor in girls but the effect size was small; other sedentary behaviours did not predict risk.

Although various theories describe mechanisms leading to differential parenting of boys and girls, there is no consensus about the extent to which parents do treat their sons and daughters differently. The last meta-analyses on the subject were conducted more than fifteen years ago, and changes in gender-specific child rearing in the past decade are quite plausible. In the current set of meta-analyses, based on 126 observational studies (15,034 families), we examined mothers' and fathers' differential use of autonomy-supportive and controlling strategies with boys and girls, and the role of moderators related to the decade in which the study was conducted, the observational context, and sample characteristics. Databases of Web of Science, ERIC, PsychInfo, Online Contents, Picarta, and Proquest were searched for studies examining differences in observed parental control of boys and girls between the ages of 0 and 18 years. Few differences were found in parents' use of control with boys and girls. Parents were slightly more controlling with boys than with girls, but the effect size was negligible (d = 0.08). The effect was larger, but still small, in normative groups and in samples with younger children. No overall effect for gender-differentiated autonomy-supportive strategies was found (d = 0.03). A significant effect of time emerged: studies published in the 1970s and 1980s reported more autonomy-supportive strategies with boys than toward girls, but from 1990 onwards parents showed somewhat more autonomy-supportive strategies with girls than toward boys. Taking into account parents' gender stereotypes might uncover subgroups of families where gender-differentiated control is salient, but based on our systematic review of the currently available large data base we conclude that in general the differences between parenting of boys versus girls are minimal.

Preschool children's interests in science

Studies of children's attitudes towards science indicate that a tendency for girls and boys to have different patterns of interest in science is established by upper primary school level. It is not know when these interest patterns develop. This paper presents the results of part of a project designed to investigate preschool children's interests in science. Individual 4 5 year-old children were asked to say what they would prefer to do from each of a series of paired drawings showing either a science and a non-science activity, or activities from two different areas of science. Girls and boys were very similar in their overall patterns of choice for science and non-science items. Within science, the average number of physical science items chosen by boys was significantly greater than the average number chosen by girls (p=.026). Girls tended to choose more biology items than did boys, but this difference was not quite significant at the .05 level (p=.054). The temporal stability of these choices was explored.

This study analyzed the amount of coverage for high school athletics in 43 newspapers with small circulation by devoting 40% of their interscholastic athletics coverage to girls in athletics, printed significantly more articles about girls' athletics than did the newspapers with medium (33%) or large (32%) circulation. Therefore, the smaller the newspaper circulation, the more equitable the coverage of athletics for girls and boys. This finding was consistent with some prior work but not all.

Mesenteric tumors are rare, especially in the pediatric population. We present a case of a 7-month-old boy with an incidental abdominal mass identified as a Primitive Myxoid Mesenchymal Tumor of Infancy derived from the small bowel mesentery. This neoplasm is part of a spectrum of myofibroblastic lesions, with distinct clinical, morphologic, IHQ reactivity, and an aggressive clinical course. There is a paucity of evidence for the management of these tumors, and surgical resection remains the mainstay of treatment.

Treatment of an assaultive, sensory-impaired adolescent through a multicomponent behavioral program.

PubMed

Luiselli, J K

1984-03-01

This project examined the effects of a multicomponent behavioral treatment program on assaultive behavior in a deaf, visually-impaired adolescent boy. Two types of assaultiveness were monitored: aggression towards adults and destruction of the physical environment. Intervention consisted of a token economy system, a response cost procedure, a "relaxation" technique, and skill training sessions. Through use of a multiple baseline across behaviors design, it was demonstrated that differentially reinforcing the absence of target behaviors on a weekly basis was the crucial ingredient in the treatment package. During a maintenance programming phase, the boy was gradually weaned off the token system. At 1- and 2-year follow-ups, no aggressive or destructive acts had occurred and the boy was showing improved communication and interpersonal skills.

The current study explored the nature of problematic (addictive) video gaming (PVG) and the association with game type, psychosocial health, and substance use. Data were collected using a paper and pencil survey in the classroom setting. Three samples were aggregated to achieve a total sample of 8478 unique adolescents. Scales included measures of game use, game type, the Video game Addiction Test (VAT), depressive mood, negative self-esteem, loneliness, social anxiety, education performance, and use of cannabis, alcohol and nicotine (smoking). Findings confirmed problematic gaming is most common amongst adolescent gamers who play multiplayer online games. Boys (60%) were more likely to play online games than girls (14%) and problematic gamers were more likely to be boys (5%) than girls (1%). High problematic gamers showed higher scores on depressive mood, loneliness, social anxiety, negative self-esteem, and self-reported lower school performance. Nicotine, alcohol, and cannabis using boys were almost twice more likely to report high PVG than non-users. It appears that online gaming in general is not necessarily associated with problems. However, problematic gamers do seem to play online games more often, and a small subgroup of gamers - specifically boys - showed lower psychosocial functioning and lower grades. Moreover, associations with alcohol, nicotine, and cannabis use are found. It would appear that problematic gaming is an undesirable problem for a small subgroup of gamers. The findings encourage further exploration of the role of psychoactive substance use in problematic gaming.

Heterotopic gastric mucosa has been described at various locations of the body; however, the polyp composed of heterotopic gastric mucosa in the small intestine is rare. A 15-year-old boy visited us for investigation of recurrent episodes of melena. Capsule endoscopy (CE) revealed a polypoid tumor in the ileum, with an active nearby hemorrhage. Contrast-enhanced computed tomography (CECT) showed a tumor in the right quadrant of the abdomen, with a diameter of about 18 × 14 mm. The patient was diagnosed with polypoid gastric heterotopia. We performed an operation to resect the lesion. The patient recovered smoothly after surgery and was discharged on postoperative day 7 and followed up for 3 months. He has not experienced gastrointestinal intestinal (GI) symptoms up to now. Giant polypoid gastric heterotopia in the small intestine is extremely rare, which can express as an occasional finding with or without symptoms. Surgical resection is the preferred therapy when symptoms appear.

To compare self-reported emotional and behavioural problems among Greek and Finnish adolescents. Youth Self-Report scores were analysed for 3373 Greek adolescents aged 18 years and 7039 Finnish adolescents aged 15-16 years from the general population in both countries. The impact of country, gender, place of residence, socioeconomic status (SES) and family stability on the scores was evaluated. Only country and gender yielded small to medium effect on the scores. Greek boys scored significantly higher than Finns on 10 of the 11 YSR syndromes, particularly on the anxious/depressed scale. Greek girls scored significantly lower than Finnish girls on the somatic complaints and delinquent behaviour scales. In general, girls scored higher than boys on both internalising and externalising problems. The gender by country interaction revealed that Finnish girls reported more externalising problems. The main differences marked in this comparison were the higher level of anxiety and depression in Greeks than Finns and the higher level of externalising problems in Finnish girls than boys. Cultural standards could play an important role in explaining these differences. Overall, it seems that only a small number of differences exist between a northern and southern European region.

The Horse Boy--attending to the stories our patients tell us.

2013-07-01

In the summer of 2007, Rupert Isaacson and Kirsten Neff set off to Mongolia on an extraordinary journey to heal their 7-year old autistic son. Their story was captured on film by a small crew, and both the resulting documentary, The Horse Boy, and the associated book have reached a wide audience. For those involved in psychiatric education, the film represents a valuable opportunity to explore a range of relevant clinical and ethical issues with their learners, including an introduction to the world of complementary and alternative medicine and the emerging discipline of narrative medicine. Perhaps most importantly, The Horse Boy is an impetus for health professionals to consider their own responsibilities when determined patients in their care undertake such remarkable quests to heal themselves or their loved ones.

Childhood aggression and its resulting consequences inflict a huge burden on affected children, their relatives, teachers, peers and society as a whole. Aggression during childhood rarely occurs in isolation and is correlated with other symptoms of childhood psychopathology. In this paper, we aim to describe and improve the understanding of the co-occurrence of aggression with other forms of childhood psychopathology. We focus on the co-occurrence of aggression and other childhood behavioural and emotional problems, including other externalising problems, attention problems and anxiety-depression. The data were brought together within the EU-ACTION (Aggression in Children: unravelling gene-environment interplay to inform Treatment and InterventiON strategies) project. We analysed the co-occurrence of aggression and other childhood behavioural and emotional problems as a function of the child's age (ages 3 through 16 years), gender, the person rating the behaviour (father, mother or self) and assessment instrument. The data came from six large population-based European cohort studies from the Netherlands (2x), the UK, Finland and Sweden (2x). Multiple assessment instruments, including the Child Behaviour Checklist (CBCL), the Strengths and Difficulties Questionnaire (SDQ) and Multidimensional Peer Nomination Inventory (MPNI), were used. There was a good representation of boys and girls in each age category, with data for 30,523 3- to 4-year-olds (49.5% boys), 20,958 5- to 6-year-olds (49.6% boys), 18,291 7- to 8-year-olds (49.0% boys), 27,218 9- to 10-year-olds (49.4% boys), 18,543 12- to 13-year-olds (48.9% boys) and 10,088 15- to 16-year-olds (46.6% boys). We replicated the well-established gender differences in average aggression scores at most ages for parental ratings. The gender differences decreased with age and were not present for self-reports. Aggression co-occurred with the majority of other behavioural and social problems, from both externalising and internalising domains. At each age, the co-occurrence was particularly prevalent for aggression and oppositional and ADHD-related problems, with correlations of around 0.5 in general. Aggression also showed substantial associations with anxiety-depression and other internalizing symptoms (correlations around 0.4). Co-occurrence for self-reported problems was somewhat higher than for parental reports, but we found neither rater differences, nor differences across assessment instruments in co-occurrence patterns. There were large similarities in co-occurrence patterns across the different European countries. Finally, co-occurrence was generally stable across age and sex, and if any change was observed, it indicated stronger correlations when children grew older. We present an online tool to visualise these associations as a function of rater, gender, instrument and cohort. In addition, we present a description of the full EU-ACTION projects, its first results and the future perspectives.

The risk for depression increases as Hispanic youth acculturate to U.S. society. This association is stronger for Hispanic girls than boys. To better understand the influence of culture and family on depressive symptoms, we tested a process-oriented model of acculturation, cultural values, and family functioning. The data came from Project RED, which included 1,922 Hispanic students (53 % girls; 86 % were 14 years old; and 84 % were U.S. born) from Southern California. We used data from 9th to 11th grade to test the influence of acculturation-related experiences on depressive symptoms over time. Multi-group structural equation analysis suggested that both family conflict and cohesion were linked with depressive symptoms. Hispanic cultural values were associated with family cohesion and conflict but the strength and direction of these relationships varied across cultural values and gender. For girls and boys, familismo and respeto were associated with higher family cohesion and lower family conflict. Moreover, gender roles were linked with higher family cohesion in girls but not in boys. These results indicate that improving family functioning will be beneficial for boys' and girls' psychological well-being. This may be achieved by promoting familismo and respeto for boys and girls and by promoting traditional gender roles for girls.

Although various theories describe mechanisms leading to differential parenting of boys and girls, there is no consensus about the extent to which parents do treat their sons and daughters differently. The last meta-analyses on the subject were conducted more than fifteen years ago, and changes in gender-specific child rearing in the past decade are quite plausible. In the current set of meta-analyses, based on 126 observational studies (15,034 families), we examined mothers’ and fathers’ differential use of autonomy-supportive and controlling strategies with boys and girls, and the role of moderators related to the decade in which the study was conducted, the observational context, and sample characteristics. Databases of Web of Science, ERIC, PsychInfo, Online Contents, Picarta, and Proquest were searched for studies examining differences in observed parental control of boys and girls between the ages of 0 and 18 years. Few differences were found in parents’ use of control with boys and girls. Parents were slightly more controlling with boys than with girls, but the effect size was negligible (d = 0.08). The effect was larger, but still small, in normative groups and in samples with younger children. No overall effect for gender-differentiated autonomy-supportive strategies was found (d = 0.03). A significant effect of time emerged: studies published in the 1970s and 1980s reported more autonomy-supportive strategies with boys than toward girls, but from 1990 onwards parents showed somewhat more autonomy-supportive strategies with girls than toward boys. Taking into account parents’ gender stereotypes might uncover subgroups of families where gender-differentiated control is salient, but based on our systematic review of the currently available large data base we conclude that in general the differences between parenting of boys versus girls are minimal.

Treatment for boys with haemophilia in China is rapidly improving; however, comprehensive outcomes have not been examined prospectively. The aim of this study was to evaluate the effect of short-term full-dose prophylaxis compared to on-demand treatment, on the Health-Related Quality of Life (HR-QoL) of boys with severe haemophilia A (HA) in China. Boys with severe HA (FVIII<1%) completed 3 months of on-demand treatment and 3 months of full-dose prophylaxis (25 FVIII IU per kg 3x per week). The primary outcomes were child- and parent-reported Canadian Hemophilia Outcomes - Kids Life Assessment Tool (CHO-KLAT) scores. The number and type of bleeds and Activities Scale for Kids (ASK) scores were also recorded. Analyses included 23 boys between 4 and 15.9 years of age. The number of bleeds decreased by 94% on prophylaxis (P < 0.0001, Wilcoxon Signed-Rank test). The mean child-reported CHO-KLAT scores for boys ≥7 years (n = 20) was 61.4 (±10.9) during on-demand treatment and 61.9 (±11.4) following short-term prophylaxis (P = 0.72, paired t-test). The mean parent-reported CHO-KLAT score during the on-demand phase was 54.4 (±10.5) with an increase of 3.8 points (±8.1; P = 0.04, paired t-test) following prophylaxis. Child-reported CHO-KLAT scores were lower in boys with severe HA in China than reported in countries with access to full-dose prophylaxis. Boys reported higher HR-QoL scores than their parents. Small improvements in ASK scores were noted following the prophylaxis phase. These changes were only significant in the parent-reported CHO-KLAT scores. Longer term prospective clinical trials are needed in China to determine the impact of prophylaxis on HR-QoL in boys with severe HA. © 2017 John Wiley & Sons Ltd.

Background : This research focused on the development, implementation and evaluation of a course on image-processing principles aimed at middle-school students. Purpose : The overarching purpose of the study was that of integrating the learning of subjects in science, technology, engineering and mathematics (STEM), and linking the learning of these subjects to the children's world and to the digital culture characterizing society today. Sample : The participants were 60 junior high-school students (9th grade). Design and method : Data collection included observations in the classes, administering an attitude questionnaire before and after the course, giving an achievement exam and analyzing the students' final projects. Results and conclusions : The findings indicated that boys' and girls' achievements were similar throughout the course, and all managed to handle the mathematical knowledge without any particular difficulties. Learners' motivation to engage in the subject was high in the project-based learning part of the course in which they dealt, for instance, with editing their own pictures and experimenting with a facial recognition method. However, the students were less interested in learning the theory at the beginning of the course. The course increased the girls', more than the boys', interest in learning scientific-technological subjects in school, and the gender gap in this regard was bridged.

Gender Differences in Child and Adolescent Social Withdrawal: A Commentary.

PubMed

Rubin, Kenneth H; Barstead, Matthew G

2014-04-01

In a manuscript entitled, "Bashful boys and coy girls: A review of gender differences in childhood shyness" Doey et al. (2013) suggest that shyness and its related constructs pose a greater developmental risk for boys compared to girls. They support this claim by citing empirical evidence suggesting that shy and anxiously withdrawn boys are responded to more negatively by important others (i.e., parents, peers, and teachers) and that the relationship between internalizing problems and anxious withdrawal is stronger for boys compared to girls. The principal aim of our commentary is to provide a critical examination of Doey et al.'s conclusions vis-à-vis gender differences in child and adolescent shyness. In this response, we begin by providing important theoretical background regarding shyness and its related constructs. Next, we critically examine the two main arguments the authors use in support of their conclusion through a review of existing empirical and theoretical work as well as the presentation of data from The Friendship Project . These data were analyzed with the specific purpose of providing an empirical test of the hypotheses implicit in Doey et al.'s primary arguments: 1) shy and anxiously withdrawn boys are responded to more negatively than girls and 2) the association between anxious withdrawal and internalizing problems is stronger for boys compared to girls. Our results indicate mixed support for these two claims. Finally, we conclude by suggesting new directions for future researchers interested in clarifying the relationship between gender and both the correlates and outcomes of childhood shyness.

Diabetes knows no age and affects millions of individuals. Preventing diabetes in children is increasingly becoming a major health policy concern and focus. The objective of this study is to project the number of children, aged 0-17 years, with diagnosed diabetes in the United States through 2030, accounting for changing demography, and diabetes and obesity prevalence rates. The study team combined historic diabetes and obesity prevalence data with US child population estimates and projections. A times-series regression model was used to forecast future diabetes prevalence and to account for the relationship between the forecasted diabetes prevalence and the lagged prevalence of childhood obesity. Overall, the prevalence of diagnosed diabetes is projected to increase 67% from 0.22% in 2010 to 0.36% in 2030. Lagged obesity prevalence in Hispanic boys and non-Hispanic black girls was significantly associated with increasing future diabetes prevalence. The study results showed that a 1% increase in obesity prevalence among Hispanic boys from the previous year was significantly associated with a 0.005% increase in future prevalence of diagnosed diabetes in children (P ≤ 0.01). Likewise, a unit increase in obesity prevalence among non-Hispanic black girls was associated with a 0.003% increase in future diabetes prevalence (P < 0.05). Obesity rates for other race/ethnicity combinations were not associated with increasing future diabetes prevalence. To mitigate the continued threat posed by diabetes, serious discussions need to focus on the pediatric population, particularly non-Hispanic black girls and Hispanic boys whose obesity trends show the strongest associations with future diabetes prevalence in children.

McGee, R; Williams, S; Nada-Raja, S

2001-08-01

This study examined the longitudinal relationship between family characteristics in early childhood. self-esteem, hopelessness and thoughts of self-harm in the midchildhood years, and suicidal ideation at ages 18 and 21. Path analysis was used to establish separate models for boys and girls. The results suggested different pathways to later suicidal ideation for boys and girls. For boys, suicidal ideation seemed to have stronger roots in childhood, with significant paths from low self-esteem and hopelessness to early thoughts of self-harm and thence to later ideation. For girls, self-esteem had a small but significant direct effect on later suicidal ideation. The findings provide support for the idea that individual characteristics such as feelings of hopelessness and low self-esteem act as "generative mechanisms," linking early childhood family characteristics to suicidal ideation in early adulthood.

We investigated the effectiveness and cost-effectiveness of a targeted human papillomavirus (HPV) vaccination program for young (15-26) men who have sex with men (MSM). We developed a compartmental model to project HPV epidemic trajectories in MSM for three vaccination scenarios: a boys program, a targeted program for young MSM only and the combination of the two over 2017-2036. We assessed the gain in quality-adjusted-life-years (QALY) in 190,000 Australian MSM. A targeted program for young MSM only that achieved 20% coverage per year, without a boys program, will prevent 49,283 (31,253-71,500) cases of anogenital warts, 191 (88-319) person-years living with anal cancer through 2017-2036 but will only stablise anal cancer incidence. In contrast, a boys program will prevent 82,056 (52,100-117,164) cases of anogenital warts, 447 (204-725) person-years living with anal cancers through 2017-2036 and see major declines in anal cancer. This can reduce 90% low- and high-risk HPV in young MSM by 2024 and 2032, respectively, but will require vaccinating ≥84% of boys. Adding a targeted program for young MSM to an existing boys program would prevent an additional 14,912 (8479-21,803) anogenital wart and 91 (42-152) person-years living with anal cancer. In combination with a boys' program, a catch-up program for young MSM will cost an additional $AUD 6788 ($4628-11,989) per QALY gained, but delaying its implementation reduced its cost-effectiveness. A boys program that achieved coverage of about 84% will result in a 90% reduction in HPV. A targeted program for young MSM is cost-effective if timely implemented. Copyright © 2017 Elsevier Ltd.

When compared to boys, girls have smaller vertebral cross-sectional area, which conveys a greater spinal flexibility, and a higher prevalence of adolescent idiopathic scoliosis. To test the hypothesis that small vertebral cross-sectional area and tall intervertebral disc height are structural characteristics of patients with adolescent idiopathic scoliosis. Using multiplanar imaging techniques, measures of vertebral cross-sectional area, vertebral height and intervertebral disc height in the lumbar spine were obtained in 35 pairs of girls and 11 pairs of boys with and without adolescent idiopathic scoliosis of the thoracic spine matched for age, height and weight. Compared to adolescents without spinal deformity, girls and boys with adolescent idiopathic scoliosis had, on average, 9.8% (6.68 ± 0.81 vs. 7.40 ± 0.99 cm(2); P = 0.0007) and 13.9% (8.22 ± 0.84 vs. 9.55 ± 1.61 cm(2); P = 0.009) smaller vertebral cross-sectional dimensions, respectively. Additionally, patients with adolescent idiopathic scoliosis had significantly greater values for intervertebral disc heights (9.06 ± 0.85 vs. 7.31 ± 0.62 mm and 9.09 ± 0.87 vs. 7.61 ± 1.00 mm for girls and boys respectively; both P ≤ 0.011). Multiple regression analysis indicated that the presence of scoliosis was negatively associated with vertebral cross-sectional area and positively with intervertebral disc height, independent of sex, age and body mass index. We provide new evidence that girls and boys with adolescent idiopathic scoliosis have significantly smaller vertebral cross-sectional area and taller intervertebral disc heights - two major structural determinants that influence trunk flexibility. With appropriate validation, these findings may have implications for the identification of children at the highest risk for developing scoliosis.

The purpose of this article is to uncover the extent of sexual gender based violence (GBV) experienced by a convenience sample of students from select counties in Liberia and to understand the disclosure experiences of those victims willing to come forward. Girls (n=758) and boys (n=1,100) were asked about their sexual GBV experiences including their disclosure experiences, if applicable. Results indicated that sexual violation (i.e., peeping or inappropriate touching) was found among both girls and boys. Sexual coercion (i.e., forced sex) was more prevalent than transactional sex (i.e., trading sex for grades or money). Both sexual coercion and transactional sex were reported by more girls than boys, yet the rates for the most severe form of sexual violence (i.e., sexual coercion) were high for both girls (30%) and boys (22%). When students were asked if they told anyone, 38% reported that they did disclose their experiences. This study contributes to a small but growing body of research to document the prevalence and types of sexual violence against children in Liberia. Consistent with other studies, the evidence shows that sexual violence against boys and girls is occurring at alarming rates. Copyright © 2014 Elsevier Ltd. All rights reserved.

Little longitudinal research has been conducted on changes in children's emotional self-regulation strategy (SRS) use after infancy, particularly for children at risk. In this study, the authors examined changes in boys' emotional SRS from toddlerhood through preschool. Repeated observational assessments using delay of gratification tasks at ages 2, 3, and 4 years were examined with both variable- and person-oriented analyses in a low-income sample of boys (N = 117) at risk for early problem behavior. Results were consistent with theory on emotional SRS development in young children. Children initially used more emotion-focused SRS (e.g., comfort seeking) and transitioned to greater use of planful SRS (e.g., distraction) by 4 years of age. Person-oriented analysis using trajectory analysis found similar patterns from 2 to 4 years, with small groups of boys showing delayed movement away from emotion-focused strategies or delay in the onset of regular use of distraction. The results provide a foundation for future researchers to examine the development of SRS in low-income young children.

Callous-unemotional (CU) traits in childhood are a developmental precursor to psychopathy, yet the origins and etiology of CU traits are not known. We examined CU traits among 12-year-old children exposed to severe early deprivation and evaluated whether a high-quality foster care intervention mitigated the development of high levels of CU traits. Participants were from the Bucharest Early Intervention Project, a randomized controlled trial of foster care for children in institutions. Children were recruited from institutions in Bucharest, Romania, along with age- and sex-matched children who were never institutionalized. Children raised in institutional settings were randomized (mean age = 22 months) to either a foster care group (n = 68) or a care-as-usual group (n = 68). CU traits were assessed at age 12.75 years in available participants from the randomized trial (n = 95) and children who were never institutionalized (n = 50). Children who experienced institutional rearing as young children had significantly higher levels of CU traits in early adolescence compared to children who were never institutionalized. Intent-to-treat analysis indicated that, among boys, CU traits were significantly lower among those who received the foster care intervention compared to those randomized to care as usual. Caregiver responsiveness to distress, but not caregiver warmth, mediated the intervention effect on CU traits in boys. These findings provide the first evidence to date that psychosocial intervention can prevent the onset of CU traits. Although severe early deprivation predicted higher levels of CU traits, high-quality foster care that emphasized responsive caregiving reduced the impact of deprivation on CU trait development for boys.

Klinefelter syndrome (47,XXY) is associated with physical, behavioral, and cognitive consequences. Deviations in brain structure and function have been reported, but structural characteristics of white matter have barely been assessed. This exploratory diffusion tensor imaging study assessed white matter microstructure in boys with 47,XXY compared with non-clinical, male controls. Additionally, both similarities and differences between 47,XXY and autism spectrum disorders (ASD) have been reported in cognition, behavior and neural architecture. To further investigate these brain-behavior pathways, white matter microstructure in boys with 47,XXY was compared to that of boys with ASD. Fractional anisotropy (FA), radial diffusivity (Dr), axial diffusivity (Da), and mean diffusivity (MD) were assessed in 47,XXY (n = 9), ASD (n = 18), and controls (n = 14), using tract-based spatial statistics. Compared with controls, boys with 47,XXY have reduced FA, coupled with reduced Da, in the corpus callosum. Boys with 47,XXY also have reduced Dr. in the left anterior corona radiata and sagittal striatum compared with controls. Compared with boys with ASD, boys with 47,XXY show reduced Da in the right inferior fronto-occipital fasciculus. Although this study is preliminary considering the small sample size, reduced white matter integrity in the corpus callosum may be a contributing factor in the cognitive and behavioral problems associated with 47,XXY. In addition, the differences in white matter microstructure between 47,XXY and ASD may be important for our understanding of the mechanisms that are fundamental to behavioral outcome in social dysfunction, and may be targeted through intervention.

The Rocky Boy Indian Reservation in north-central Montana has had difficulty in establishing a dependable source of drinking water. In 1993, due to a water shortage on the Rocky Boy Reservation, the Chippewa-Cree Council began negotiating water rights with the State of Montana in order to construct a pipeline that would pump water from an off-reservation source to reservation homes. The proposed plan is to pipe water from the Tiber Dam, located approximately 53 miles west, to the Rocky Boy Indian Reservation for treatment and distribution. The purpose of this internship was to initiate a ground water investigation on themore » Rocky Boy Reservation by writing a report and submitting it to the Tribe. The intern undertook this project because he felt there was no need for an expensive pipeline and from familiarity with the Reservation, thought a dependable supply of drinking water may already exist on the Reservation. The intern obtained topographic maps from the USGS, requested well logs, conducted a literature survey, and requested planimetric maps from the Montana Bureau of Mines. The preliminary ground water report has been completed, but final results of the investigation are dependent upon the review by the Rocky Boy Tribal Council. This intern report contains biographical data on the intern and his mentor, as well as the completed preliminary report submitted to the Tribal Council.« less

To determine the amount of time children play outdoors and examine associations with weekday, weekend and after-school physical activity (PA), sedentary behavior (SB), and weight-status (normal-weight, overweight/obese). Data were extracted from Project BEAT (Toronto, 2010-2011; www.beat.utoronto.ca). Children's (n=856; mean age=11±0.6years) PA and SB were measured using accelerometry. Outdoor play (OP) was assessed via parental report and collapsed into three categories (<1h/day, 1-2h/day, >2h/day) and differences in anthropometric and PA characteristics were assessed. 55.1%, 37.2%, and 7.7% of children played outdoors for <1h/day, 1-2h/day and >2h/day, respectively, on weekdays. OP was higher on weekends and in boys. OP was associated with SB, light PA and MVPA at all time-points, whereby children attaining <1h/day had lower activity profiles. Boys playing outdoors for <1h/day were more likely to be overweight/obese and had lower PA levels than normal weight boys. However, overweight/obese boys who spent >2h/day playing outdoors had PA profiles similar to normal weight counterparts. Encouraging children to spend more time outdoors may be an effective strategy for increasing PA, reducing SB, and preventing excess weight gain (particularly boys' play).

In a manuscript entitled, “Bashful boys and coy girls: A review of gender differences in childhood shyness” Doey et al. (2013) suggest that shyness and its related constructs pose a greater developmental risk for boys compared to girls. They support this claim by citing empirical evidence suggesting that shy and anxiously withdrawn boys are responded to more negatively by important others (i.e., parents, peers, and teachers) and that the relationship between internalizing problems and anxious withdrawal is stronger for boys compared to girls. The principal aim of our commentary is to provide a critical examination of Doey et al.’s conclusions vis-à-vis gender differences in child and adolescent shyness. In this response, we begin by providing important theoretical background regarding shyness and its related constructs. Next, we critically examine the two main arguments the authors use in support of their conclusion through a review of existing empirical and theoretical work as well as the presentation of data from The Friendship Project. These data were analyzed with the specific purpose of providing an empirical test of the hypotheses implicit in Doey et al.’s primary arguments: 1) shy and anxiously withdrawn boys are responded to more negatively than girls and 2) the association between anxious withdrawal and internalizing problems is stronger for boys compared to girls. Our results indicate mixed support for these two claims. Finally, we conclude by suggesting new directions for future researchers interested in clarifying the relationship between gender and both the correlates and outcomes of childhood shyness.

An 11-year-old boy with serologically confirmed Chlamydophila pneumoniae infection presented with clinical, laboratory, and echocardiographic changes consistent with myopericarditis. No reports on C. pneumoniae myopericarditis in children are found in the medical literature. The boy, previously healthy, presented with fever, rash, constitutional symptoms, elevated acute phase reactants, elevated cardiac enzymes, and high brain natriuretic peptide levels. Hemodynamic instabilities, including hypotension and mild hypoxia, were noted. Two-dimensional echocardiographic findings showed mildly depressed left ventricular systolic function and small pericardial effusion. Requiring inotropic support, the boy was treated with azithromycin 10 mg/kg once daily for 7 days and a single dose of intravenous immunoglobulin 2 g/kg. He recovered fully with improved left ventricular systolic function before hospital discharge. An early definitive diagnosis is essential to knowing the etiology of pediatric myocarditis. Specific therapy may play role in the management and prognosis of this disorder.

Calls to engage men and boys in efforts to promote health, prevent violence and advance gender equality have grown in recent years. However, there remains little evidence or reflection on how most effectively to change harmful norms related to masculinity. The study addresses this gap by exploring the perspectives of participants in the Young Men Initiative (YMI), an innovative programme that aimed to promote healthier masculinities among boys attending vocational high schools in several Balkan countries through educational workshops, residential retreats and a social marketing campaign. Qualitative data were collected through 37 in-depth interviews and 11 focus-group discussions with boys, youth facilitators and teachers. Findings from four schools (in Belgrade, Sarajevo, Prishtina and Zagreb) suggest that several elements of the programme resonated strongly with participants and supported their meaningful engagement in project activities. Five themes emerged as most salient in identifying how and why specific aspects of YMI positively influenced participants: personal reflection, experience-based learning, connections with youth facilitators, new peer groups and aspirational messaging. Building on these insights, the study highlights potentially useful strategies for other programmes seeking to reach boys and transform their understanding of masculinity. PMID:26680537

To explore why boys eat less fruit and vegetables (F&V) than girls, using longitudinal data following pupils from the age of 12.5 to 15.5 years, including perceived accessibility, modelling, intention, preferences, self-efficacy and knowledge of recommendations as potential mediators. A longitudinal study, based on data collected among the control schools within the intervention project 'Fruits and Vegetables Make the Marks'. This sample contains 896 6th and 7th graders from 20 randomly selected elementary schools within two Norwegian counties. Questionnaires were administered in May 2002 and May 2005 (when the participants were in 9th and 10th grade in 18 secondary elementary schools). In single mediation analyses all determinants mediated parts of the gender difference, but only preferences decreased the gender difference to a level below statistical significance. Preferences alone explained 81% of the gender difference. In the multiple mediation analyses, the six mediators together explained 91% of the gender difference, but only preferences and perceived accessibility contributed uniquely to the explanation, with 25% and 10% respectively. Preference appears as the strongest mediator of the difference in F&V intakes between boys and girls. Further research should explore why girls like F&V more than boys.

Purpose This paper examines the relationship between family functioning (e.g. communication, closeness, problem solving, behavioral control) and adolescent weight status and relevant eating and physical activity behaviors. Methods Data are from EAT 2010 (Eating and Activity in Teens), a population-based study that assessed eating and activity among socioeconomically and racially/ethnically diverse youth (n = 2,793). Adolescents (46.8% boys, 53.2% girls) completed anthropometric assessments and surveys at school in 2009–2010. Multiple linear regression was used to test the relationship between family functioning and adolescent weight, dietary intake, family meal patterns, and physical activity. Additional regression models were fit to test for interactions by race/ethnicity. Results For adolescent girls, higher family functioning was associated with lower body mass index z-score and percent overweight, less sedentary behavior, higher intake of fruits and vegetables, and more frequent family meals and breakfast consumption. For adolescent boys, higher family functioning was associated with more physical activity, less sedentary behavior, less fast food consumption, and more frequent family meals and breakfast consumption. There was one significant interaction by race/ethnicity for family meals; the association between higher family functioning and more frequent family meals was stronger for non-white boys compared to white boys. Overall, strengths of associations tended to be small with effect sizes ranging from - 0.07 to 0.31 for statistically significant associations. Conclusions Findings suggest that family functioning may be protective for adolescent weight and weight-related health behaviors across all race/ethnicities, although assumptions regarding family functioning in the homes of overweight children should be avoided given small effect sizes.

Grip strength and body composition in Turkana pastoralist children and adolescents.

PubMed

Little, Michael A

2017-03-01

In an earlier study, age changes and sex differences in grip strength were documented for adult Turkana pastoralists of Kenya (Little and Johnson, 1986). The objective here is to characterize age changes and sex differences in grip strength of Turkana children and adolescents in the context of arm lean tissue composition, and in comparison with other African, African-American, and non-Western populations. Anthropometric measurements, derived body composition values, and grip strength measures (maximum voluntary contraction) were taken on a sample of 232 nomadic Turkana pastoralist children (94 boys and 138 girls) aged 3 to 21 years. Relationships were tested between grip strength (in Newtons) and mid-upper arm (brachium) lean tissue cross-sectional areas. Comparisons were made among several different ethnic groups. Turkana children and adolescents had low arm muscle (derived lean tissue) and grip strength values when compared with U.S. NHANES percentile references. Girls' percentile rankings were greater than boys' percentile rankings for muscle and for grip strength. Both boys and girls were intermediate when compared with other non-Western populations and U.S. strength grip reference values. Correlations between grip strength and arm lean tissue areas were highly significant for both boys and girls. The greater relative muscle size and grip strength values of late adolescent girls compared to boys is consistent with an earlier study of adults. The difference is likely to result from greater physical subsistence activity and greater access to food in girls than in boys. Several suggestions are given to explain why Turkana youths have relatively small muscle sizes. © 2016 Wiley Periodicals, Inc.

Purpose This study aimed to explore the intelligence profiles of Chinese school-aged boys with high-functioning autism spectrum disorder (HFASD) and attention-deficit/hyperactivity disorder (ADHD). Additionally, differences in intelligence quotient (IQ) between the HFASD group and the ADHD group were examined. Patients and methods Thirty-two boys with HFASD, 58 boys with ADHD, and 39 typically developing (TD) boys aged 6–16 years participated in this study. The ADHD group was divided into subgroups: ADHD-I (predominantly inattentive) and ADHD-C (combined type). (The ADHD-H [hyperactive] group was excluded because of small sample size). The Wechsler Intelligence Scale for Children-IV Chinese version was administered to every participant, and the FSIQ (Full-Scale IQ) score was used as the measure of IQ. Results Both boys with HFASD and ADHD (ADHD-I and ADHD-C) showed impairments in Processing Speed Index and FSIQ, as compared to the TD group. Lower Verbal Comprehension Index scores were found in the ASD and ADHD-I groups. Interestingly, Working Memory Index was only impaired in children with ADHD. Additionally, equivalent Perceptual Reasoning Index (PRI) scores were found among the HFASD, ADHD, and TD groups. Conclusion Results indicated that both children with ADHD and HFASD have difficulty in processing speed, which may be explained by these children having neurodevelopmental disorders. These results also indicated that working memory appears to only be impacted by having ADHD. Children with ASD are known to have language difficulties while children with ADHD typically display working memory deficits; thus, these findings were expected. PMID:28670123

1999-06-01

The human figure drawings of a group of emotionally-disturbed boys were compared with those of a group of well-adjusted boys closely matched for chronological age and another for mental age. A comparison based on Koppitz's (1968) original emotional indicators and another, based on new UK norms, showed that the emotionally-disturbed children included significantly more indicators in their drawings than their well-adjusted peers. Although this difference was statistically significant it is actually quite small. In addition, there were no differences among the groups in the kinds of indicators they exhibited. The usefulness of the Koppitz test as a tool for clinical use is questioned.

The study aim was to objectively assess levels of sedentary time, light, moderate and vigorous physical activity (PA) among 10-12 year olds across five European countries and to examine differences in sedentary time and PA according to gender and country. 686 children (mean age = 11.6 ± 0.8 years, 53% girls, mean BMI = 19.0 ± 3.4 kg/m(2)) from Belgium, Greece, Hungary, the Netherlands and Switzerland wore Actigraph accelerometers and had at least 2 weekdays with minimum 10 h-wearing time and 1 weekend day with minimum 8 h-wearing time. Data were analyzed using multivariate analyses of covariance. Girls spent significantly more time sedentary (500 minutes/day) than boys (474 minutes/day) and significantly less time in light (267 minutes/day) and moderate-to-vigorous PA (32 minutes/day) than boys (284 minutes/day; 43 minutes/day respectively; p < 0.001). 4.6% of the girls and 16.8% of the boys met moderate-to-vigorous PA recommendations of at least 60 minutes/day. Greek boys were more sedentary (510 minutes/day; all at p < 0.05) than other boys. Dutch girls were less sedentary (457 minutes/day; all at p < 0.05) than other girls. Swiss girls displayed more moderate-to-vigorous PA (43 minutes/day; at p < 0.05) than other girls. Large proportions of children across different European countries did not meet PA recommendations and spent a lot of time sedentary. Mean time spent in moderate-to-vigorous PA was significantly lower than the recommended 60 minutes. Obesity prevention programmes focusing on both decreasing sedentary time and increasing light, moderate and vigorous PA are needed for European children, particularly girls.

Neonatal vitamin A supplementation associated with a cluster of deaths and poor early growth in a randomised trial among low-birth-weight boys of vitamin A versus oral polio vaccine at birth

PubMed Central

2014-01-01

Background The effect of oral polio vaccine administered already at birth (OPV0) on child survival was not examined before being recommended in 1985. Observational data suggested that OPV0 was harmful for boys, and trials have shown that neonatal vitamin A supplementation (NVAS) at birth may be beneficial for boys. We set out to test this research question in a randomised trial. Methods The trial was carried out at the Bandim Health Project, Guinea-Bissau. We planned to enrol 900 low-birth weight (LBW) boys in a randomised trial to investigate whether NVAS instead of OPV0 could lower infant mortality for LBW boys. At birth, the children were randomised to OPV (usual treatment) or VAS (intervention treatment) and followed for 6 months for growth and 12 months for survival. Hazard Ratios (HR) for mortality were calculated using Cox regression. We compared the individual anthropometry measurements to the 2006 WHO growth reference. We compared differences in z-scores by linear regression. Relative risks (RR) of being stunted or underweight were calculated in Poisson regression models with robust standard errors. Results In the rainy season we detected a cluster of deaths in the VAS group and the trial was halted immediately with 232 boys enrolled. The VAS group had significantly higher mortality than the OPV0 group in the rainy season (HR: 9.91 (1.23 – 80)). All deaths had had contact with the neonatal nursery; of seven VAS boys enrolled during one week in September, six died within two months of age, whereas only one died among the six boys receiving OPV (p = 0.05). Growth (weight and arm-circumference) in the VAS group was significantly worse until age 3 months. Conclusion VAS at birth instead of OPV was not beneficial for the LBW boys in this study. With the premature closure of the trial it was not possible to answer the research question. However, the results of this study call for extra caution when testing the effect of NVAS in the future.

2017-11-01

A higher incidence rate (IR) of acute gastrointestinal (GI) infections associated with prenatal exposure to p,p'-DDE was suggested by the results in two studies. Given the high mortality rate due to childhood diarrhea in some countries with ongoing use of DDT, additional data on this association is relevant for those making decisions about vector-borne disease control. To evaluate whether higher levels of prenatal exposure to p,p'-DDE and p,p'-DDT increase the risk of having diarrhea in a birth cohort of boys from tropical Mexico. Our analysis was based on 747 boys whose exposure was measured in maternal serum collected at delivery (2002-2003). Mothers reported the number of diarrhea episodes of their children during in-person interviews. The median age of the children at their last interview was 21.4 months. Poisson regression models were fitted to estimate adjusted incidence rate ratios (aIRR) of diarrhea by levels of p,p'-DDE and p,p'-DDT. Overall, there were 1.7 episodes of diarrhea per child-year. Among those in the highest category of exposure (> 9µg DDE/g serum lipid), the aIRR for diarrhea was 1.14 (95% CI: 0.94, 1.30) compared to those in the lowest category of exposure (≤ 3µg/g). Among boys living in the urban area, the corresponding aIRR was 1.39 (95% CI: 1.07-1.80). Among rural boys, no associations emerged. Although the results were consistent with a small positive association, the overall estimate was not precise. While urban boys in this study appeared to be more susceptible to DDE-associated diarrhea, a ready explanation for such increased susceptibility was not apparent. Copyright © 2017 Elsevier Inc.

Predicting the onset of smoking in boys and girls.

PubMed

Charlton, A; Blair, V

1989-01-01

The problem of the high prevalence of smoking among girls and young women is of great concern. In an attempt to identify the factors which influence girls and boys respectively to attempt smoking, the study examines social background, advertising and brand awareness, knowledge, teaching and personal beliefs in conjunction as predictors of smoking. In this study which involved the administration of identical pre- and post-test questionnaires to a sample of boys and girls aged 12 and 13 years, nine variables expressed by never-smokers at pre-test stage were assessed as predictors of immediate future smoking. The two tests were administered 4 months apart to 1125 boys and 1213 girls in northern England. The nine variables included were parental smoking, best friends' smoking, perceived positive values of smoking, perceived negative values of smoking, correct health knowledge, cigarette-brand awareness, having a favourite cigarette advertisement, having a cigarette-brand sponsored sport in four top favourites on television. One group received teaching about smoking between the pre- and post-tests and this was also included as a variable. For boys, no variable investigated had any consistently statistically significant correlation with the uptake of smoking. The most important predictor of smoking for boys, having a best friend who smoked, was significant on application of the chi 2 test (P 0.037), although it was non-significant when included singly in a logistic regression model (0.094); the discrepancy was probably due to the small number of best friends known to smoke. For girls, four variables were found to be significant predictors of smoking when included singly in a logistic regression.(ABSTRACT TRUNCATED AT 250 WORDS)

The effects of single-sex compared with coeducational schooling on students' performance and attitudes: a meta-analysis.

Pahlke, Erin; Hyde, Janet Shibley; Allison, Carlie M

2014-07-01

Proponents of single-sex (SS) education believe that separating boys and girls, by classrooms or schools, increases students' achievement and academic interest. In this article, we use meta-analysis to analyze studies that have tested the effects on students of SS compared with coeducational (CE) schooling. We meta-analyzed data from 184 studies, representing the testing of 1.6 million students in Grades K-12 from 21 nations, for multiple outcomes (e.g., mathematics performance, mathematics attitudes, science performance, educational aspirations, self-concept, gender stereotyping). To address concerns about the quality of research designs, we categorized studies as uncontrolled (no controls for selection effects, no random assignment) or controlled (random assignment or controls for selection effects). Based on mixed-effects analyses, uncontrolled studies showed some modest advantages for single-sex schooling, for both girls and boys, for outcomes such as mathematics performance but not for science performance. Controlled studies, however, showed only trivial differences between students in SS versus CE, for mathematics performance (g = 0.10 for girls, 0.06 for boys) and science performance (g = 0.06 for girls, 0.04 for boys), and in some cases showed small differences favoring CE schooling (e.g., for girls' educational aspirations, g = -0.26). Separate analyses of U.S. studies yielded similar findings (e.g., for mathematics performance g = 0.14 for girls and 0.14 for boys). Results from the highest quality studies, then, do not support the view that SS schooling provides benefits compared with CE schooling. Claims that SS schooling is particularly effective for U.S. ethnic minority boys could not be tested due to the lack of controlled studies on this question.

2016-03-12

The mechanism that initiates the onset of puberty is largely unknown but the age of onset is mainly under genetic control and influenced by environmental factors including nutrition. Familial forms of constitutional delay of puberty (CDP) suggest the involvement of genetic factors. The purpose of this study is to describe the presentation and the mode of inheritance of CDP in a series of familial cases. A retrospective, single center study was carried out over 10 years on 48 probands (14 girls and 34 boys) from 48 families seen for CDP with a familial component. Of the 48 probands, 46 (96 %) had at least one affected 1(st) degree relatives and 2 (4 %, 2 boys) had only 2(nd) degree relatives affected. In girls, 11 families (79 %) exhibited exclusive maternal inheritance, 1 (7 %) paternal inheritance and 2 (14 %) both maternal and paternal inheritance. In boys, 14 families (41 %) exhibited exclusive maternal inheritance, 12 (35 %) paternal inheritance and 8 (24 %) both maternal and paternal inheritance. In the boys with bilineal inheritance, the ages at onset of puberty (16 ± 1.41 years) and at evaluation (16.05 ± 2.47 years) were higher than in those with unilineal inheritance (15.25 ± 0.35 and 15.1 ± 0.42 years respectively), but the difference was not significant. In girls exclusive maternal inheritance seems to be the major mode of inheritance whereas for boys the mode of inheritance was almost equally maternal, paternal or bilineal. Clinical phenotype of boys with bilineal inheritance seems to be more severe, but the difference did not reach statistical significance, perhaps because of the small sample size. This greater severity of the phenotype in boys with bilineal inheritance is likely due to inheriting different puberty timing genes from each parent. Future research should be directed at identifying such genes.

The role of parents' perceptions of the neighborhood environment in determining children's active commuting to and from school (ACS) is understudied. This study examined the association between parents' perceptions of neighborhood social cohesion, perceived neighborhood safety, and their children's ACS. This cross-sectional analysis (n = 857 from 81 elementary schools in Texas) examined baseline data from the Texas Childhood Obesity Prevention Policy Evaluation project. Participants had a mean age of 9.6 (0.6) years, and 50% were girls. Mixed effects logistic regression models were used to assess gender-stratified associations between parent's perceived social cohesion and children's ACS and their perception of neighborhood safety. A positive significant association was observed between levels of perceived social cohesion and children's ACS for boys (P = 0.047); however, an inverse significant association was observed among girls (P = 0.033). Parents of boys living in neighborhoods with medium to high social cohesion were more likely to perceive their neighborhood as safe compared with parents living in neighborhoods with low social cohesion, though nonsignificant. Perceived neighborhood safety for walking and biking was associated with greater ACS among boys (P = 0.003). Our study findings indicate that both social and physical environments are important factors in determining ACS among boys.

Lost in (cyber)space: finding two adolescent boys hiding from their own humanity.

Tyminski, Robert

2015-04-01

This article explores the intense psychological effects of compulsive Internet use, which has become increasingly common among adolescent boys and young men. Two cases are presented and discussed to illustrate some of the psychic distortions around thinking and feeling, as these occurred in the analysis of a mid-adolescent boy and of another patient in later adolescence. A kind of narcissistic omnipotence grounded in magical thinking appeared to take root in their minds, and it led to an avoidant pattern in relationships because of such strong wishes for both distance and control. A short review of the conceptual origins of magical thinking underscores its continued relevance because so many now engage with the Internet. In addition, Anzieu's idea of the 'skin ego' is applied to the clinical case material to provide a theoretical framework for the developmental challenges that can appear in adolescent boys who seek to use the Internet as a form of psychic container. Emerging problems that immersion in the Internet might bring into our practices, for example the depleting effects of massive projective identification, are considered and discussed, along with the obvious ways in which using the Internet can be beneficial for connecting with others, for creating new platforms of expression, and for education. © 2015, The Society of Analytical Psychology.

Acculturation, Enculturation, and Symptoms of Depression in Hispanic Youth: The Roles of Gender, Hispanic Cultural Values, and Family Functioning

The risk for depression increases as Hispanic youth acculturate to U.S. society. This association is stronger for Hispanic girls than boys. To better understand the influence of culture and family on depressive symptoms, we tested a process-oriented model of acculturation, cultural values, and family functioning. The data came from Project RED, which included 1,922 Hispanic students (53 % girls; 86 % were 14 years old; and 84 % were U.S. born) from Southern California. We used data from 9th to 11th grade to test the influence of acculturation-related experiences on depressive symptoms over time. Multi-group structural equation analysis suggested that both family conflict and cohesion were linked with depressive symptoms. Hispanic cultural values were associated with family cohesion and conflict but the strength and direction of these relationships varied across cultural values and gender. For girls and boys, familismo and respeto were associated with higher family cohesion and lower family conflict. Moreover, gender roles were linked with higher family cohesion in girls but not in boys. These results indicate that improving family functioning will be beneficial for boys’ and girls’ psychological well-being. This may be achieved by promoting familismo and respeto for boys and girls and by promoting traditional gender roles for girls. PMID:22627624

An uncontaminated urine culture is a prerequisite for the diagnosis of a urinary tract infection. However, this may be difficult to obtain in small children. We have studied the frequency of ballooning of the prepuce in non-circumcised boys and vaginal reflux in girls during voiding as a possible cause of contaminated urine cultures. All micturating cystourethrograms (MCUG) performed in our institution over the last 5 years in children aged 0-15 years were reviewed retrospectively for ballooning of the foreskin or vaginal reflux as a potential source of bacterial contamination. The voiding pictures were routinely done with the catheter present for the first voiding cycle and then removed on the second void. A total of 526 children (77.4 % boys, 22.6 % girls) were eligible for the study. Ballooning of the foreskin was identified on the micturition pictures of 115 (38 %) boys, with the frequency significantly higher in boys aged <12 months [odds ratio (OR) 4.1; 95 % confidence interval (CI) 2.1-7.3)] and boys with vesicoureteral reflux (OR 1.6; 95 % CI 1.06-2.4). Seventeen girls (14.3 %) showed vaginal reflux. No correlation with age or vesicoureteral reflux was found in the girls. Ballooning of the prepuce or vaginal reflux was seen on a fluoroscopic MCUG in a large proportion of children during their voiding. This normal phenomenon might cause contaminated urine cultures when the urine is obtained by bag or clean catch.

The implementation, fidelity, and receipt of a self-determination-theory-based after-school physical activity intervention (Action 3:30) delivered by teaching assistants (TAs) was examined using a mixed-methods process evaluation. Physical activity motivation and need satisfaction were reported by 539 participants at baseline, the end of intervention, and 4-month follow-up. Pupil- and TA-reported autonomy-support and teaching efficacy were collected alongside interviews with 18 TAs and focus groups with 60 participants. Among intervention boys there were small increases in identified, introjected, and external motivation and no differences in need satisfaction. Among girls, intrinsic and identified motivation and autonomy and relatedness were lower in the intervention group. Qualitative evidence for fidelity was moderate, and boys reported greater need satisfaction than girls. TAs provided greater structure than involvement or autonomy-support and felt least efficacious when facing school-based challenges. The findings highlight the refinements needed to enhance theoretical fidelity and intervention effectiveness for boys and girls.

INTERNET DEPENDENCE IN CHINESE HIGH SCHOOL STUDENTS: RELATIONSHIP WITH SEX, SELF-ESTEEM, AND SOCIAL SUPPORT.

Zhang, Ruiping

2015-08-01

This cross-sectional study investigated the relationships among self-esteem, social support, and Internet dependence. A sample of young people aged between 15 and 18 years old (M age = 16.3 yr., SD = 0.7; 470 boys, 441 girls) completed measures of the Rosenberg Self-Esteem Scale, the Perceived Social Support Scale, and the Internet Dependence Test. According to the cognitive-behavioral model of problematic Internet use, social support should mediate the relationship between self-esteem and Internet dependence. Furthermore, based on previous research it was predicted that boys would score higher on Internet dependence than women. Support for this model was obtained. Internet dependent students were more likely to be boys. Self-esteem and social support were negatively correlated with Internet dependence. The relationship between self-esteem and Internet dependence was mediated by social support. Although the effect sizes were small, the findings of the present study are of significance in investigating adolescents' Internet dependence.

Children's contact with their mother's violent partner is a potentially important variable for understanding conduct problems among children exposed to intimate partner violence (IPV). Within the context of a treatment study evaluating a parenting intervention (Project Support) for families exiting a domestic violence shelter, this study tested four hypotheses regarding children's postshelter contact with their mother's violent partner: (1) participation in Project Support decreases the frequency of children's contact with their mother's violent partner; (2) postshelter contact is positively associated with children's conduct problems and is associated more strongly for girls than boys; (3) frequency of contact mediates Project Support's effects on children's conduct problems; and (4) frequency of contact is positively associated with IPV and partner-child aggression, and these latter associations help explain effects of contact on children's conduct problems. Participants were 66 women (26 White) with a child (32 girls) between 4 and 9 years. Families were assessed every 4 months for 20 months after departure from a domestic violence shelter. Project Support reduced the extent of partner-child contact. In addition, within-subject changes in contact over time were associated with girls', but not boys', conduct problems, and it partially mediated effects of Project Support on girls' conduct problems. Higher average levels of contact over time were also positively associated with further incidents of IPV and partner-child aggression, and partner-child aggression helped explain effects of contact on children's conduct problems. Children's postshelter contact with the mother's violent partner relates positively to several negative family outcomes.

Linguistic camouflage in girls with autism spectrum disorder.

Autism spectrum disorder (ASD) is diagnosed more frequently in boys than girls, even when girls are equally symptomatic. Cutting-edge behavioral imaging has detected "camouflaging" in girls with ASD, wherein social behaviors appear superficially typical, complicating diagnosis. The present study explores a new kind of camouflage based on language differences. Pauses during conversation can be filled with words like UM or UH, but research suggests that these two words are pragmatically distinct (e.g., UM is used to signal longer pauses, and may correlate with greater social communicative sophistication than UH). Large-scale research suggests that women and younger people produce higher rates of UM during conversational pauses than do men and older people, who produce relatively more UH. Although it has been argued that children and adolescents with ASD use UM less often than typical peers, prior research has not included sufficient numbers of girls to examine whether sex explains this effect. Here, we explore UM vs. UH in school-aged boys and girls with ASD, and ask whether filled pauses relate to dimensional measures of autism symptom severity. Sixty-five verbal school-aged participants with ASD (49 boys, 16 girls, IQ estimates in the average range) participated, along with a small comparison group of typically developing children (8 boys, 9 girls). Speech samples from the Autism Diagnostic Observation Schedule were orthographically transcribed and time-aligned, with filled pauses marked. Parents completed the Social Communication Questionnaire and the Vineland Adaptive Behavior Scales. Girls used UH less often than boys across both diagnostic groups. UH suppression resulted in higher UM ratios for girls than boys, and overall filled pause rates were higher for typical children than for children with ASD. Higher UM ratios correlated with better socialization in boys with ASD, but this effect was driven by increased use of UH by boys with greater symptoms. Pragmatic language markers distinguish girls and boys with ASD, mirroring sex differences in the general population. One implication of this finding is that typical-sounding disfluency patterns (i.e., reduced relative UH production leading to higher UM ratios) may normalize the way girls with ASD sound relative to other children, serving as "linguistic camouflage" for a naïve listener and distinguishing them from boys with ASD. This first-of-its-kind study highlights the importance of continued commitment to understanding how sex and gender change the way that ASD manifests, and illustrates the potential of natural language to contribute to objective "behavioral imaging" diagnostics for ASD.

The purpose of this research was to investigate the relationship between distance to school and levels of physical activity and sedentary behavior in UK adolescents. Participants were 1385 adolescents (boys n = 531; mean age 14.7 years). Boys living within two miles of school and girls living within 5 miles of school were more likely to report high levels (> or = 60 min per day) of weekday leisure time physical activity. Differences in weekday leisure time physical activity were accounted for by active travel time. There were no differences in sedentary behavior time by distance to school. Journeys, whether active or motorized, most often took place with friends. Further research should investigate wider physical and social environmental influences on active travel.

Wilson, Nathan John; Shuttleworth, Russell; Stancliffe, Roger; Parmenter, Trevor

2012-06-01

Researchers in intellectual disability have had limited theoretical engagement with mainstream theories of masculinity. In this article, the authors consider what mainstream theories of masculinity may offer to applied research on, and hence to therapeutic interventions with, men and boys with intellectual disability. An example from one research project that explored male sexual health illustrates how using masculinity theory provided greater insight into gendered data. Finally, we discuss the following five topics to illustrate how researchers might use theories of masculinity: (a) fathering, (b) male physical expression, (c) sexual expression, (d) men's health, and (e) underweight and obesity. Theories of masculinity offer an additional framework to analyze and conceptualize gendered data; we challenge researchers to engage with this body of work.

To what degree does being male or female influence the development of manual skills in pre-pubescent children? This question is important because of the emphasis placed on developing important new manual skills during this period of a child's education (e.g. writing, drawing, using computers). We investigated age and sex-differences in the ability of 422 children to control a handheld stylus. A task battery deployed using tablet PC technology presented interactive visual targets on a computer screen whilst simultaneously recording participant's objective kinematic responses, via their interactions with the on-screen stimuli using the handheld stylus. The battery required children use the stylus to: (i) make a series of aiming movements, (ii) trace a series of abstract shapes and (iii) track a moving object. The tasks were not familiar to the children, allowing measurement of a general ability that might be meaningfully labelled ‘manual control’, whilst minimising culturally determined differences in experience (as much as possible). A reliable interaction between sex and age was found on the aiming task, with girls' movement times being faster than boys in younger age groups (e.g. 4–5 years) but with this pattern reversing in older children (10–11 years). The improved performance in older boys on the aiming task is consistent with prior evidence of a male advantage for gross-motor aiming tasks, which begins to emerge during adolescence. A small but reliable sex difference was found in tracing skill, with girls showing a slightly higher level of performance than boys irrespective of age. There were no reliable sex differences between boys and girls on the tracking task. Overall, the findings suggest that prepubescent girls are more likely to have superior manual control abilities for performing novel tasks. However, these small population differences do not suggest that the sexes require different educational support whilst developing their manual skills. PMID:24523931

Girls in detail, boys in shape: gender differences when drawing cubes in depth.

PubMed

Lange-Küttner, C; Ebersbach, M

2013-08-01

The current study tested gender differences in the developmental transition from drawing cubes in two- versus three dimensions (3D), and investigated the underlying spatial abilities. Six- to nine-year-old children (N = 97) drew two occluding model cubes and solved several other spatial tasks. Girls more often unfolded the various sides of the cubes into a layout, also called diagrammatic cube drawing (object design detail). In girls, the best predictor for drawing the cubes was Mental Rotation Test (MRT) accuracy. In contrast, boys were more likely to preserve the optical appearance of the cube array. Their drawing in 3D was best predicted by MRT reaction time and the Embedded Figures Test (EFT). This confirmed boys' stronger focus on the contours of an object silhouette (object shape). It is discussed whether the two gender-specific approaches to drawing in three dimensions reflect two sides of the appearance-reality distinction in drawing, that is graphic syntax of object design features versus visual perception of projective space. © 2012 The British Psychological Society.

Blood lead levels in children living in three communities, at different risks of lead pollution

We carried out a survey on blood lead levels in children living in three different communities in Umbria, Italy: Corciano, a small community (12,500 inhabitants), free of lead-using factories and with light traffic; Perugia, a medium-sized city (146,500 inhabitants); Deruta, a small community (7500 inhabitants) whose economy is based mainly on the production of artistic pottery, mostly in small home-operated factories. The study sample was made up of 539 children (275 boys and 264 girls); 156 of them attended nursery school (aged 3-6) and 383 primary school (aged 6-11). The mean blood lead level was significantly higher in Deruta thanmore » in Corciano (9.7 vs 8.3 micrograms/dl); Deruta children whose parents were occupationally exposed to lead had significantly higher blood lead levels than children of lead-unexposed parents (10.7 vs 9.0 micrograms/dl). The mean blood lead level was higher in Perugia than in Corciano children. On the average boys had higher blood lead levels than girls in all of the groups. We conclude that blood lead levels were low in the groups of children studied. Nevertheless children of ceramic workers and children living in a medium-sized city had greater lead absorption than children living in the control area.« less

Five hundred and thirty-two pregnant women were interviewed about their psychosocial health at the beginning of pregnancy. According to various factors including alcoholism, mental disease and criminality among the women and their husbands the families were divided in three groups of different degrees according to psychosocial stress. The pregnancies, deliveries and the 497 live-born children in these families have been investigated with prospective methods. Data concerning the psychological development and psychiatric health of the child were attained by interviewing the mother and evaluating the child during visits to home (age 1 and 4). The physical health and development of the children has been followed by prospective data achieved from the child welfare centers. At one year of age 452 of the children (226 boys, 226 girls) and at four-five years of age 412 of the children (202 boys, 210 girls) were evaluated by the Griffith's Development Scales. Findings from these evaluations can now be related to a number of factors concerning the psychosocial situation, pediatric riskfactors etc. With the prospective, longitudinal methods used in this project interesting results concerning sex differences related to the mental development have been found. At one year of age girls had higher scores than boys on the Griffiths-subscale measuring hearing-and-speech abilities. At four years of age several significant differences between the sexes were found. Girls had more "even" Griffiths-profiles and scored higher than boys in several Griffiths-subscales. The greatest differences at four years of age were found concerning personal-social function and eye-hand-coordination. Boys seem to be specially vulnerable to the psychosocial situation in their homes as the Griffiths-results at four years of age are lower among boys from homes with psychosocial stress compared to other boys. It should be very interesting to follow and study what these sex differences mean concerning future development, the occurrence of psychopathology school difficulties.

Cross-gender Social Normative Effects for Violence in Middle School: Do Girls Carry a Social Multiplier Effect for At-risk Boys?

2014-01-01

A social multiplier effect is a social interaction in which the behavior of a person in a social network varies with the normative behavior of others in the network, also known as an endogenous interaction. Policies and intervention efforts can harness social multiplier effects because, in theory, interventions on a subset of individuals will have “spillover effects” on other individuals in the network. This study investigates potential social multiplier effects for violence in middle schools, and whether there is evidence for a social multiplier effect transmitted from girls to boys. Three years of longitudinal data (2003–2005) from Project Northland Chicago (PNC) were used to investigate this question, with a sample consisting of youth in Grades 6 through 8 in 61 Chicago Public Schools (N = 4233 at Grade 6, N = 3771 at Grade 7, and N = 3793 at Grade 8). The sample was 49.3% female, and primarily African American (41.9%) and Latino/a (28.7%), with smaller proportions of whites (12.9%), Asians (5.2%) and other ethnicities. Results from two sets of regression models estimating the effects of 20th (low), 50th (average), and 80th (high) percentile scores for girls and boys on levels of violence in each gender group revealed evidence for social multiplier effects. Specifically, boys and girls were both influenced by social multiplier effects within their own gender group, and boys were also affected by normative violence scores among girls, typically those of the best-behaved (20th percentile) girls. The finding that girls may have positive social influence on boys’ levels of violent behavior extends prior findings of beneficial social effects of girls on boys in the domains of education and risky driving. Further, this social normative effect presents a potential opportunity to improve school-based intervention efforts for reducing violence among youth by leveraging girls as carriers of a social multiplier effect for reduced violence in the middle school environmental context, particularly among boys, who are at greater risk.

The potential effect of gender on intellectual abilities remains controversial. The purpose of this research was to analyze gender differences in cognitive test performance among children from continuous age groups. For this purpose, the normative data from 7 domains of the newly developed neuropsychological test battery, the Evaluación Neuropsicológica Infantil [Child Neuropsychological Assessment] (Matute, Rosselli, Ardila, & Ostrosky-Solis, 2007), were analyzed. The sample included 788 monolingual children (350 boys, 438 girls) ages 5 to 16 years from Mexico and Colombia. Gender differences were observed in oral language (language expression and language comprehension), spatial abilities (recognition of pictures seen from different angles), and visual (Object Integration Test) and tactile perceptual tasks, with boys outperforming girls in most cases, except for the tactile tasks. Gender accounted for only a very small percentage of the variance (1%-3%). Gender x Age interactions were observed for the tactile tasks only. It was concluded that gender differences during cognitive development are minimal, appear in only a small number of tests, and account for only a low percentage of the score variance.

Practical applications of sulfate-reducing bacteria to control acid mine drainage at the Lilly/Orphan Boy Mine near Elliston, Montana

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

Canty, M.

The overall purpose of this document is to provide a detailed technical description of a technology, biological sulfate reduction, which is being demonstrated under the Mine Waste Technology Pilot Program, and provide the technology evaluation process undertaken to select this technology for demonstration. In addition, this document will link the use of the selected technology to an application at a specific site. The purpose of this project is to develop technical information on the ability of biological sulfate reduction to slow the process of acid generation and, thus, improve water quality at a remote mine site. Several technologies are screenedmore » for their potential to treat acid mine water and to function as a source control for a specific acid-generating situation: a mine shaft and associated underground workings flooded with acid mine water and discharging a small flow from a mine opening. The preferred technology is the use of biological sulfate reduction. Sulfate-reducing bacteria are capable of reducing sulfate to sulfide, as well as increasing the pH and alkalinity of water affected by acid generation. Soluble sulfide reacts with the soluble metals in solution to form insoluble metal sulfides. The environment needed for efficient sulfate-reducing bacteria growth decreases acid production by reducing the dissolved oxygen in water and increasing pH. A detailed technical description of the sulfate-reducing bacteria technology, based on an extensive review of the technical literature, is presented. The field demonstration of this technology to be performed at the Lilly/Orphan Boy Mine is also described. Finally, additional in situ applications of biological sulfate reduction are presented.« less

Motor performance is an important factor for health. Already in childhood, motor performance is associated with, e.g., obesity and risk factors for cardiovascular diseases. It is widely believed that the motor performance of children has declined over recent years. However, this belief is lacking clear evidence. The objective of this study was to examine trends in motor performance of first grade students during a period of 10 years (2006-2015). We examined trends in (a) aerobic fitness, (b) strength, (c) speed, and (d) balance for boys and girls separately and considered body mass index (BMI) as a potential confounder. From 2006 to 2015, we tested 5,001 first graders [50.8% boys; mean age 6.76 (0.56) years] of 18 primary schools in Germany. Each year between 441 and 552 students of the same schools were surveyed. Performance tests were taken from the Motorik-Module Study and the "German Motor Ability Test": "6-min run," "push-ups," "20-m sprint," and "static stand." Linear regression models were conducted for statistical analysis. A slightly negative trend in aerobic fitness performance was revealed in boys (β = -0.050; p  = 0.012) but not in girls. In the strength performance test no trend over time was detected. Performance in speed (boys: β = -0.094; girls: β = -0.143; p  ≤ 0.001) and balance tests (boys: β = -0.142; girls: β = -0.232; p  ≤ 0.001) increased over time for both boys and girls. These findings held true when BMI was considered. This study only partly supported the assumption that motor performance of children has declined: in our study, aerobic fitness declined (only in boys), while strength remained stable and speed and balance even increased in both sexes. Moreover, it seems as if BMI can explain changes in performance only to a small extent. Changed lifestyles might be a substantial cause. Further research on recent trends of motor performance and interacting variables is needed to support the results of our study and to provide more knowledge on causes of these trends.

Born Small for Gestational Age and Poor School Performance - How Small Is Too Small?

2017-01-01

To assess the relationship between severity of small for gestational age (SGA) and the risk of poor school performance, and to investigate whether adult stature modifies this risk. 1,088,980 Swedish children born at term between 1973 and 1988 were categorized into severe SGA (less than -3 standard deviations (SD) of expected birth weight), moderate SGA (-2.01 to -3 SD), mild SGA (-1.01 to -2 SD), and appropriate for gestational age (-1 to 0.99 SD). The risk of poor school performance at the time of graduation from compulsory school (grades <10th percentile) was calculated using unconditional logistic regression models and adjusted for socio-economic factors. In a sub-analysis, we stratified boys by adult stature, and adjusted for maternal but not paternal height. All SGA groups were significantly associated with an increased risk of poor school performance, with adjusted odds ratios and 95% confidence intervals ranging from 1.85 (1.65-2.07) for severe SGA to 1.25 (1.22-1.28) for mild SGA. In the sub-analysis, all birth weight groups were associated with an increased risk of poor school performance among boys with short stature compared to those with non-short stature. Mild SGA is associated with a significantly increased risk of poor school performance, and the risk increases with severity of SGA. Further, this risk diminishes after adequate catch-up growth. © 2017 S. Karger AG, Basel.

Lab-in-a-box @ school: Exiting hands-on experiments in soft matter physics

2015-03-01

Soft materials like liquids and polymers are part of everyday life, yet at school, this topic is rarely touched. Within the priority program SPP 1064 'Nano- and Microfluidics' of the German Science Foundation, we designed an outreach project that allows pupils (age 14 to 18) to perform hands-on experiments (www.labinabox.de). The experiments allow them e.g. to feel viscosity and viscoelasticity, experience surface tension or see structure formation. We call the modus operandi 'subjective experiments' to contrast them with the scientifically objective experiments, which pupils often describe as being boring. Over a dozen different experiments under the topic 'physics of fluids' are collected in a big box that travels to the school. Three other topics of boxes are available, 'physics of light, 'physics of liquid crystals', and 'physics of adhesion and friction'. Each experiment can be performed by 1-3 pupils within 10 - 20 min. That way, each scholar can perform 6 to 8 different small experiments within one topic. 'Subjective experiments' especially catch the attention of girls without disadvantaging boys. Both are fascinated by the hands-on physics experience and are therefore eager to perform also 'boring' objective experiments. Morover, before/after polls reveal that their interest in physics has greatly advanced. The project can easily be taken over and/or adapted to other topics in the natural sciences. Financial support of the German Science Foundation DFG is acknowledged.

Normative data for penile length in Turkish newborns.

Local normative data for penile size will aid physicians in clinical practice. There are no studies on stretched penile length (SPL) in newborn Turkish boys. To establish normative data for SPL of newborn Turkish boys and compare these with data from different countries. 514 newborn Turkish boys, who were not small for gestational age (SGA) or premature, were included in this cross-sectional study. SPLs of the newborns were measured by the same investigator. The correlations between SPL and gestational age, weight, length, and head circumference were evaluated. The 3(rd) percentile value for SPL was found as 3.00 cm in these Turkish newborns. Positive correlations were shown between SPL and height (r=0.240, p<0.001), weight (r=0.251, p<0.001), and head circumference (r=0.235, p<0.001). Multiple linear regression analysis showed that SPL positively correlated with height and head circumference (p=0.021 and p= 0.042, respectively). This is the largest study on SPL in newborns from our country. This normative data can be used in clinical practice for defining micropenis.

Large population-based studies suggest that systematic measures of maternal sensitivity predict later risk for overweight and obesity. More work is needed to establish the developmental timing and potential moderators of this association. The current study examined the association between maternal sensitivity at 6 months of age and BMI z score measures at 48 months of age, and whether sex moderated this association. Longitudinal Canadian cohort of children from birth (the MAVAN project). This analysis was based on a dataset of 223 children (115 boys, 108 girls) who had structured assessments of maternal sensitivity at 6 months of age and 48-month BMI data available. Mother-child interactions were videotaped and systematically scored using the Maternal Behaviour Q-Sort (MBQS)-25 items, a standardized measure of maternal sensitivity. Linear mixed-effects models and logistic regression examined whether MBQS scores at 6 months predicted BMI at 48 months, controlling for other covariates. After controlling for weight-relevant covariates, there was a significant sex by MBQS interaction (P=0.015) in predicting 48 month BMI z. Further analysis revealed a strong negative association between MBQS scores and BMI in girls (P=0.01) but not boys (P=0.72). Logistic regression confirmed that in girls only, low maternal sensitivity was associated with the higher BMI categories as defined by the WHO (i.e. "at risk for overweight" or above). A significant association between low maternal sensitivity at 6 months of age and high body mass indices was found in girls but not boys at 48 months of age. These data suggest for the first time that the link between low maternal sensitivity and early BMI z may differ between boys and girls. Copyright © 2014 Elsevier Ltd. All rights reserved.

The present study was designed to assess physical activity, sedentary behaviours and dietary habits among adolescents in Kuwait and to compare the differences between genders. A cross-sectional study was conducted among secondary-school children who participated in the Arab Teens Lifestyle Study (ATLS), a multi-centre collaborative project. Secondary schools in Kuwait. Adolescents (463 boys and 443 girls), aged 14-19 years. Nearly half (44·6 %) of the boys and three-quarters (76·0 %) of the girls did not meet the recommended daily physical activity levels (≥2520 MET-min/week, moderate to vigorous intensity). Nearly all (96·3 % of boys and 96·7 % of girls) adolescents reported spending >2 h/d on screen time, with girls found to spend more time per day watching television (P = 0·02) and using a computer (P < 0·001). The large majority of the adolescents reported skipping breakfast and not having milk and milk products, vegetables and fruit daily, while nearly two-thirds of the boys and girls had sugar-sweetened drinks on more than 3 d/week. Compared with girls, boys reported consuming more fruit (3·4 v. 2·8 times/week, P = 0·001), dairy products (4·5 v. 3·6 times/week, P = 0·001) and energy drinks (1·3 v. 1·1 times/week, P = 0·003). The majority of the Kuwaiti adolescents, especially girls, do not perform adequate physical activity, spend more time on sedentary activities and have unhealthy dietary practices. The findings emphasize an urgent need for implementing an appropriate intervention for promoting physical activity, healthy eating and reducing sedentary behaviours among these children.

In the literature, verbal fluency (VF) is generally described as a female-favoring task. Although it is conceivable that this sex difference only evolves during adolescence or adulthood under influence of sex steroids, this has never been investigated in young adolescents. First, to assess sex differences in VF performance and regional brain activation in adolescents. Second, to determine if untreated transsexual adolescents differ from their sex of birth with regard to VF performance and regional brain activation. Twenty-five boys, 26 girls, 8 Male-to-Female transsexual adolescents (MtFs), and 14 Female-to-Male transsexual adolescents (FtMs) were tested in a cross-sectional study, while performing a phonetic and semantic VF task within an MRI scanner. Functional MRI response during VF task. Boys and girls produced similar amounts of words, but the group MtFs produced significantly more words in the phonetic condition compared to control boys, girls, and FtMs. During the semantic condition, no differences were found. With regard to brain activity, control boys showed more activation in the right Rolandic operculum, a small area adjacent to Broca's area, compared to girls. No significant differences in brain activity were found comparing transsexual adolescents, although sub-threshold activation was found in the right Rolandic operculum indicating a trendwise increase in activation from control girls to FtMs to MtFs to control boys. The better performance of MtFs is consistent with our expectation that MtFs perform better on female-favoring tasks. Moreover, they produced more words than girls and FtMs. Even though a trendwise linear increase in brain activity between the four groups only approached significance, it may indicate differences in individuals with gender identity disorder compared to their birth sex. Although our findings should thus be interpreted with caution, they suggest a biological basis for both transgender groups performing in-between the two sexes. © 2013 International Society for Sexual Medicine.

2009-04-01

Resistin has been linked with obesity and hypothesized as a potential marker of insulin resistance in addition to being linked with acute inflammation. However, these links are still highly controversial in humans. Our goal was to examine resistin levels in relation to obesity, insulin resistance and inflammation markers in a large population of Asian children and adolescents. Children and adolescents (n=3472) aged 6-18 years, boys (n=1765) and girls (n=1707), were assessed for body size parameters, pubertal development, blood lipids, glucose, insulin, resistin, C-reactive protein (CRP), adiponectin and complement C3 (C3) levels. Resistin increased with central obesity in both genders but not with simple adiposity in boys. Several markers associated with central obesity correlated in a gender-specific fashion with plasma resistin. Waist circumference, fat-mass percentage, waist-to-height ratio and body mass index (BMI) positively correlated with resistin in both genders. Blood lipids such as triglycerides, nonesterified fatty acids (NEFA) and low-density lipoprotein cholesterol, diastolic and systolic blood pressure correlated positively with resistin in boys. NEFA, high-density lipoprotein cholesterol (negatively) and inflammation markers, such as CRP and C3, positively correlated with resistin in girls. There was no correlation between resistin and adiponectin, and no association of adiponectin with resistin quintiles in either boys or girls. In both boys and girls, resistin tended to decrease with age, with girls having higher levels than boys. Few indices of insulin resistance were linked with plasma resistin in either gender. In this population, plasma resistin levels are a weak biochemical marker of metabolic dysfunction defined by central obesity, adiposity and inflammation and does not predict insulin resistance. Only a small proportion of resistin variation can be explained by factors related to metabolic syndrome, suggesting that resistin is not strongly implicated in a concentration-dependent fashion in any of the examined pathologies.

BackgroundWe intended to evaluate the effects of physical activity (PA) programs on renal function in obese boys.MethodsThirty-nine boys participated in one of the following three groups: soccer (SG, n=13), traditional PA (AG, n=13), and sedentary control (CG, n=13). SG and AG were involved in 6-month PA programs, involving three sessions/week for 60-90 min. Anthropometric measurements, body composition, creatinine and cystatin C plasmatic levels, and estimated glomerular filtration rate (eGFR) were evaluated.ResultsAt baseline (n=39), age and lean mass index (LMI) were positively correlated with creatinine levels. After 6 months, both intervention groups decreased the BMI z-score and waist circumference, while the CG increased the body fat percentage (BFP). LMI increased in all the groups. SG presented a small increment in plasma creatinine and a decrease in the eGFR values, using the Schwartz formula. Concerning the cystatin C levels and eGFR values using Filler (cystatin C-based) or Combined Zappitelli (creatinine/cystatin C-based) formulas, no significant changes were observed in any group.ConclusionThe combined Zappitelli formula showed no significant impact of PA on eGFR in obese boys. Although plasma creatinine is significantly influenced by lean body mass, cystatin C is likely to be a more accurate marker of renal function in this population.

The shrinking world of girls at puberty: Violence and gender-divergent access to the public sphere among adolescents in South Africa

2015-01-01

Participatory mapping was undertaken with single-sex groups of grade 5 and grade 8–9 children in KwaZulu-Natal. Relative to grade 5 students, wide gender divergence in access to the public sphere was found at grade 8–9. With puberty, girls' worlds shrink, while boys' expand. At grade 5, female-defined community areas were equal or larger in size than those of males. Community area mapped by urban grade 8–9 girls, however, was only one-third that of male classmates and two-fifths that of grade 5 girls. Conversely, community area mapped by grade 8–9 boys was twice that of grade 5 boys. Similar differences emerged in the rural site. No female group rated a single community space as more than ‘somewhat safe’. Although curtailed spatial access is intended to protect girls, grade 8–9 girls reported most places in their small navigable areas as very unsafe. Expanded geographies of grade 8–9 boys contained a mix of safe and unsafe places. Reducing girls' access to the public sphere does not increase their perceived safety, but may instead limit their access to opportunities for human development. The findings emphasise the need for better violence prevention programming for very young adolescents. PMID:25303092

This study investigates the progression of family cohesion perceptions and depressive symptoms during the character development stage in adolescents. Data were used from the Taiwan Youth Project. The final sample comprised 2,690 adolescents with 1,312 girls (48.8%; M age = 13.0 yr., SD = 0.5). Latent curve growth analysis was employed to explore these developments. Seventh-grade girls reported greater family cohesion and more depressive symptoms than boys, and boys reported greater growth in family cohesion than girls. However, progression of depressive symptoms was not associated with the child's sex. Higher perceived family cohesion in Grade 7 correlated with less increase of depressive symptoms from Grades 9 to 11. The long-term positive influence of family cohesion on depressive symptoms is discussed.

Representative surveys indicate that eating disorders are an increasing problem, especially among (pre)adolescents. We assessed the effects of a German school-based primary prevention program ("Torera") for seventh graders. Torera especially relates to pathological eating behavior in the realm of bulimia nervosa or binge eating disorder. The program is built upon two previously evaluated modules for sixth graders with a gender-specific adaption. The coeducational intervention involves nine manual-guided lessons touching a wide range of eating-related problems. Twenty-two Thuringian secondary schools (n = 256 boys and 277 girls, aged 11-13 years at baseline) participated in a trial with 2 control groups (untreated and pretreated) with pre-post assessment. Primary outcomes were conspicuous eating behavior and body self-esteem, measured by standardized questionnaires (SCOFF, EAT-26D, and FBeK). Girls and students at risk showed significant improvement with small (d = 0.35) to medium (d = 0.66) effect sizes on eating behavior, significantly mediated by body self-esteem. Boys only improved with respect to eating attitudes, revealing a small effect size (d = 0.35). With relatively low implementation costs (about 2.50 per student), Torera provides an efficient model for reducing risky eating behavior and strengthening body self-esteem without negative side effects. To improve the effectiveness of the intervention, further research efforts focusing on at-risk groups (secondary prevention) and structural actions for prevention (e.g., offering healthy school catering) are needed.

To compare the mesio-distal tooth sizes and dental arch dimensions in Malay boys and girls with Class I, Class II and Class III malocclusions. The dental casts of 150 subjects (78 boys, 72 girls), between 12 and 16 years of age, with Class I, Class II and Class III malocclusions were used. Each group consisted of 50 subjects. An electronic digital caliper was used to measure the mesio-distal tooth sizes of the upper and lower permanent teeth (first molar to first molar), the intercanine and intermolar widths. The arch lengths and arch perimeters were measured with AutoCAD software (Autodesk Inc., San Rafael, CA, U.S.A.). The mesio-distal dimensions of the upper lateral incisors and canines in the Class I malocclusion group were significantly smaller than the corresponding teeth in the Class III and Class II groups, respectively. The lower canines and first molars were significantly smaller in the Class I group than the corresponding teeth in the Class II group. The lower intercanine width was significantly smaller in the Class II group as compared with the Class I group, and the upper intermolar width was significantly larger in Class III group as compared with the Class II group. There were no significant differences in the arch perimeters or arch lengths. The boys had significantly wider teeth than the girls, except for the left lower second premolar. The boys also had larger upper and lower intermolar widths and lower intercanine width than the girls. Small, but statistically significant, differences in tooth sizes are not necessarily accompanied by significant arch width, arch length or arch perimeter differences. Generally, boys have wider teeth, larger lower intercanine width and upper and lower intermolar widths than girls.

Growth status among low-income Mexican and Mexican-American elementary school children.

Childhood obesity remains a problem among Latino children in the United States. Acculturation to an American diet and sedentary lifestyle may be causative factors. The research purpose was to assess child growth status, including sitting height, in relation to acculturation among Mexican and Mexican-American children. Anthropometric measures of weight, height, and sitting height were taken in a cross-sectional survey of Mexican and Mexican-American elementary school children (N = 484) in Phoenix, Arizona. Height-for-age (HAZ), weight-for-age (WAZ), and body mass index (BMI) Z-scores were calculated based on the Centers for Disease Control 2000 growth reference. Sitting height Z-scores (SHZ) were determined from the NHANES III reference values. Questions about language usage were asked of the children as a proxy for acculturation. Differences in growth measures and acculturation between those born in the United States or Mexico were evaluated by chi-square or t-tests. The mean HAZ value (-0.23) was close to the reference median. There were no significant differences in HAZ or SHZ by birth country or gender. WAZ values for boys were significantly higher than for girls. More girls (64%) than boys (54%) had normal BMIs. More Mexican-born boys (28%) were obese than Mexican-born girls (17%; P = 0.026) in comparison to the US-born boys (31%) and girls (24%; P = n.s.). Acculturation scale score and male gender predicted a small percentage of the variation in BMIZ.

The aim of the current study was to provide wrist circumference (WrC) and body frame size (height/WrC) percentile values in Turkish children and adolescents aged 6-17 years. In this cross-sectional study, the data of "Determination of Anthropometric Measures of Turkish Children and Adolescents" (DAMTCA II) study in Kayseri/Turkey were used. A total of 4330 observations were recorded (1931 boys, 2399 girls). The WrC and frame size reference values were produced with generalized additive models for location, scale and shape. The WrC percentiles (3rd-97th) were calculated. The frame size (height/WrC) was estimated as small, medium, and large (<15 th , 15-85 th , and ≥85 th percentiles, respectively). For both genders, WrC linearly increased with age (13.0-16.8 cm for boys and 12.5-15.5 cm for girls). In boys and girls, the mean ± standard deviation of WrC is 13.00±0.89 cm and 12.48±0.93 cm (6 years) and increases to 16.83±1.16 and 15.58±0.86 cm (17 years), respectively. The WrC values in all age groups were higher in boys compared with girls. The increment in frame size from 6 to 17 years were 1.25 cm in boys and 0.85 cm in girls. WrC is a simple, easy-to-detect anthropometric index which is not subject to measurement errors. Additionally, WrC can be used both to decide about frame size and to determine metabolic risks related to obesity. We consider that this easy-to-get anthropometric index can be used both in screening procedures and clinical assessment procedure for obesity-related metabolic consequences.

Context influences decision-making in boys with attention-deficit/hyperactivity disorder: A comparison of traditional and novel choice-impulsivity paradigms.

Attention-deficit/hyperactivity disorder (ADHD) is characterized by an impaired ability to maintain attention and/or hyperactivity/impulsivity. Impulsivity is frequently defined as the preference for small, immediate rewards over larger, delayed rewards, and has been associated with a variety of negative outcomes such as risky behavior and academic difficulty. Extant studies have uniformly utilized the traditional paradigm of presenting two response choices, which limits the generalization of findings to scenarios in which children/adolescents are faced with dichotomous decisions. The current study is the first to examine the effect of manipulating the number of available response options on impulsive decision-making in boys with and without ADHD. A total of 39 boys (ADHD = 16, typically developing [TD] = 23) aged 8-12 years completed a traditional two-choice impulsivity task and a novel five-choice impulsivity task to examine the effect of manipulating the number of choice responses (two vs five) on impulsive decision-making. A five-choice task was utilized as it presents a more continuous array of choice options when compared to the typical two-choice task, and is comparable given its methodological similarity to the two-choice task. Results suggested that boys with ADHD were significantly more impulsive than TD boys during the two-choice task, but not during the five-choice task. Collectively, these findings suggest that ADHD-related impulsivity is not ubiquitous, but rather dependent on variation in demands and/or context. Further, these findings highlight the importance of examining ADHD-related decision-making within the context of alternative paradigms, as the exclusive utilization of two-choice tasks may promote inaccurate conceptualizations of the disorder.

The PREVASC study addresses the primary prevention of asthma in infants and small children. The objective of this study is to investigate whether a multifaceted prenatally started intervention strategy in high-risk infants leads to a decrease in the occurrence of (severe) asthma and whether a refinement of the prevention strategy leads to an increase in the adherence to the prevention program. The primary prevention program includes house dust mite impermeable bed coverings, education on breast feeding, hypoallergenic feeding, timing of introduction of solid food and smoking cessation. A total of 888 infants were prenatally included. By the time of inclusion the mothers were 3-7 months pregnant. About 27 infants were excluded from the study and 18 dropped out. Of the remaining 843 infants 535 had a first-degree familial predisposition of asthma (high-risk group), whereas a reference group of 308 (162 boys) infants was not predisposed for asthma in the first-degree (low-risk group). To evaluate the (cost-)effectiveness of the preventive intervention, 222 (118 boys) infants of the high-risk group allocated to the intervention group and 221 (112 boys) allocated to a control group are followed up. The low-risk infants served as controls to evaluate the predictive value of high risk (first-degree familial predisposition of asthma). The infants are followed from the prenatal stage until they reach the age of 6 yr. The remaining 92 high-risk infants were included in an optimized randomized-clinical adherence trial (RCAT). Of these 92 infants, 45 (20 boys) were allocated to an intervention group and 47 (24 boys) to a control group. Until now all infants have been followed for at least 1 yr.

"I like to treat others as others would treat me": the development of prosocial selves in an urban youth organization.

PubMed

Deutsch, Nancy L

2005-01-01

The development of moral identity is linked to a sense of self that is prosocial and connected to others. Youth organizations, if designed appropriately, may provide a setting for social interactions and relationships in which youth can enact and receive validation for moral behaviors and develop prosocial selves. This chapter reports on findings from a four-year study of identity construction within an urban Boys and Girls Club. The author conducted interviews and photography projects with seventeen youth ages twelve to eighteen, all of whom were active club members. Over half described their race or ethnicity as black or African American, while others were Hispanic, Afro-Latino, white, or other. All of them either lived in the housing project near the club or had close ties to it. Both boys and girls describe themselves as rooted in a rich relational milieu that promoted prosocial identities. The importance of respect emerged as a key theme in the teens' narratives about themselves and their activities. The author found that the club served as a site for the development of prosocial traits in an environment characterized by respectful and supportive relationships.

A Longitudinal Analysis of Hispanic Youth Acculturation and Cigarette Smoking: The Roles of Gender, Culture, Family, and Discrimination

PubMed Central

2013-01-01

Introduction: Risk for smoking initiation increases as Hispanic youth acculturate to U.S. society, and this association seems to be stronger for Hispanic girls than boys. To better understand the influence of culture, family, and everyday discrimination on cigarette smoking, we tested a process-oriented model of acculturation and cigarette smoking. Methods: Data came from Project RED (Reteniendo y Entendiendo Diversidad para Salud), which included 1,436 Hispanic students (54% girls) from Southern California. We used data from 9th to 11th grade (85% were 14 years old, and 86% were U.S. born) to test the influence of acculturation-related experiences on smoking over time. Results: Multigroup structural equation analysis suggested that acculturation was associated with increased familismo and lower traditional gender roles, and enculturation was linked more with familismo and respeto. Familismo, respeto, and traditional gender roles were linked with lower family conflict and increased family cohesion, and these links were stronger for girls. Familismo and respeto were further associated with lower discrimination. Conversely, fatalismo was linked with worse family functioning (especially for boys) and increased discrimination in both the groups. Discrimination was the only predictor of smoking for boys and girls. Conclusions: In all, the results of the current study indicate that reducing discrimination and helping youth cope with discrimination may prevent or reduce smoking in Hispanic boys and girls. This may be achieved by promoting familismo and respeto and by discouraging fatalistic beliefs. PMID:23109671

The influence of a game-making project on male and female learners' attitudes to computing

NASA Astrophysics Data System (ADS)

Robertson, Judy

2013-03-01

There is a pressing need for gender inclusive approaches to engage young people in computer science. A recent popular approach has been to harness learners' enthusiasm for computer games to motivate them to learn computer science concepts through game authoring. This article describes a study in which 992 learners across 13 schools took part in a game-making project. It provides evidence from 225 pre-test and post-test questionnaires on how learners' attitudes to computing changed during the project, as well as qualitative reflections from the class teachers on how the project affected their learners. Results indicate that girls did not enjoy the experience as much as boys, and that in fact, the project may make pupils less inclined to study computing in the future. This has important implications for future efforts to engage young people in computing.

Energy expenditure and enjoyment of small-sided soccer games in overweight boys.

Toh, Sharon H; Guelfi, Kym J; Wong, Patricia; Fournier, Paul A

2011-06-01

When space is limited, it would be preferable to play multiple small-sided soccer games (SSG) simultaneously on small courts, rather than a single game, to maximise participation. Given that the layouts of most gymnasiums incorporate several badminton courts, we examined whether energy expenditure and enjoyment of SSG on a badminton court (6.1×13.4 m) were comparable to larger court dimensions (volleyball and basketball courts; 9×18 m and 14.2×26.5 m, respectively). Twelve overweight boys played 30 min three-a-side SSG on each court in a counterbalanced design. During SSG, energy expenditure was estimated via accelerometry, heart rate was monitored and ratings of perceived exertion (RPE) and enjoyment were obtained. Energy expenditure was similar between badminton and volleyball courts, but lower than the basketball court (p<.05). Mean% HR(max) was significantly lower on the badminton court than the volleyball and basketball courts (p<.05). There was no effect of court size on RPE or enjoyment (p>.05). These results suggest that it may be preferable to play SSG on a larger court when space is available. Alternatively, when space is limited the difference in energy expenditure between court sizes can be accounted for by an additional 2.3 min of play on a badminton court.

The present study examined the influence of maternal and child characteristics on parenting behaviors in a genetically informative study. The participants were 976 twins and their mothers from the Colorado Longitudinal Twin Study and the Twin Infant Project. Indicators of positive parenting were coded during parent-child interactions when twins were 7-36 months old. Child cognitive abilities and affection were independent correlates of positive parenting. There were significant gender differences in the magnitude of genetic and environmental influences on positive parenting, with shared environmental influences on parenting of girls and additive genetic influences on parenting of boys. Girls received significantly more positive parenting than boys. Differences in etiology of positive parenting may be explained by developmental gender differences in child cognitive abilities and affection, such that girls may have more rewarding interactions with parents, evoking more positive parenting.

2018-01-01

The purpose of this study was to assess the acute effect of high-intensity interval exercise (HIIE) and moderate-intensity exercise (MIE) on glucose tolerance, insulin sensitivity and fat oxidation in young boys. Eleven boys (8.8 ± 0.8 y) completed three conditions: 1) HIIE; 2) work-matched MIE; and 3) rest (CON) followed by an oral glucose tolerance test (OGTT) to determine glucose tolerance and insulin sensitivity (Cederholm index). Fat oxidation was measured following the OGTT using indirect calorimetry. There was no effect for condition on plasma [glucose] and [insulin] area under the curve (AUC) responses following the OGTT (P > 0.09). However, there was a "trend" for a condition effect for insulin sensitivity with a small increase after HIIE (P = 0.04, ES = 0.28, 9.7%) and MIE (P = 0.07, ES = 0.21, 6.5%) compared to CON. There was an increase in fat oxidation AUC following HIIE (P = 0.008, ES = 0.79, 38.9%) compared to CON, but with no differences between MIE and CON and HIIE and MIE (P > 0.13). In conclusion, 7- to 10-year-old boys may have limited scope to improve insulin sensitivity and glucose tolerance after a single bout of HIIE and MIE. However, fat oxidation is augmented after HIIE but not MIE.

Low density lipoprotein subclasses in Asian and Caucasian adolescent boys.

2006-01-01

South Asian adults are known to have very high rates of Coronary heart disease (CHD) and insulin resistance and, even as adolescents, may show higher risk factors for CHD. The aim of this study was to investigate the prevalence of small, dense low density lipoprotein (sdLDL) subclasses in a cohort of adolescent boys. The specific objective was to investigate the relationship between measures of fatness, ethnicity and LDL diameter in this cohort. Preformed native (non-denaturing) polyacrylamide 3-13% gradient gels and a multipurpose vertical electrophoresis system were used for the separation of LDL sub-fractions in a single school year cohort of boys aged 15-16 years (n=135). Latex beads and thyroglobulin standards were used to construct a calibration curve in order to calculate LDL particle diameters by regression (Total Lab Software v1.11). ANOVA was used to compare LDL size among different ethnic groups (SPSS and Stat View). The study sample was comprised of 45.2% Caucasians, 41.5% East Asians and 13.3% from the Indian subcontinent (South Asians). There was a non-significant trend for South Asians to have a lower LDL diameter than either Caucasians or East Asian boys which was independent of % total body fat (%TBF) and body mass index (BMI). This is the first adolescent cohort to examine sdLDL which included Caucasians, East and South Asians. It appears that the higher risk profile for CHD and diabetes noted in South Asian adults may be evident even during adolescence.

A 1-year-old boy with no underlying disorder presented with non-bilious vomiting since 4 days before admission. He was referred to our hospital and was diagnosed with a small bowel obstruction due to an intraabdominal tumor. Laparotomy revealed an intestinal volvulus with a soft and lobulated tumor arising from the mesentery. The resected tumor with a small part of the small bowel was diagnosed as lipoblastoma histologically. From a literature review, mesenteric lipoblastoma with an intestinal volvulus showed different characteristics such as greater frequency of vomiting and less frequency of abdominal mass as clinical symptoms, and the size of the tumor was smaller than that of the tumor without the intestinal volvulus.

Prenatal sex hormones (maternal and amniotic fluid) and gender-related play behavior in 13-month-old Infants.

PubMed

2009-02-01

Testosterone, estradiol, and progesterone levels were measured in the second trimester of pregnancy in maternal serum and amniotic fluid, and related to direct observations of gender-related play behavior in 63 male and 63 female offspring at age 13 months. During a structured play session, sex differences in toy preference were found: boys played more with masculine toys than girls (d = .53) and girls played more with feminine toys than boys (d = .35). Normal within-sex variation in prenatal testosterone and estradiol levels was not significantly related to preference for masculine or feminine toys. For progesterone, an unexpected significant positive relationship was found in boys between the level in amniotic fluid and masculine toy preference. The mechanism explaining this relationship is presently not clear, and the finding may be a spurious one. The results of this study may indicate that a hormonal basis for the development of sex-typed toy preferences may manifest itself only after toddlerhood. It may also be that the effect size of this relationship is so small that it should be investigated with more sensitive measures or in larger populations.

We report here on a 6-year-old boy referred to the laboratory for karyotyping and SHOX microdeletion testing. The most significant clinical findings in this boy were small stature, Madelung deformity, facial dysmorphism, mild mental retardation and behavioral problems. R-, G- and RTBG-banding chromosome analysis showed a normal male karyotype. Fine molecular characterization, by FISH, of terminal Xp microdeletion revealed an associated partial duplication. Further refinement of the molecular analysis indicated an inverted duplication of the Xp22.31-Xp22.32 (13.7 Mb) region including the STS, VCX-A and KAL1 genes, associated with a terminal Xp deletion Xp22.33-Xpter (3.6 Mb) encompassing the SHOX and ARSE genes. Such rearrangements have been characterized for other chromosomal pairs, but this is the first reported male patient involving the short arm of the X chromosome. Molecular analysis of the maternal and patient's microsatellite markers showed interchromatid mispairing leading to non-allelic homologous recombination to be the most likely mechanism underlying this rearrangement. This case highlights the importance of clinically driven FISH investigations in order to uncover cryptic micro-rearrangements. Copyright (c) 2007 Wiley-Liss, Inc.

Social competence and learning difficulties: Teacher perceptions.

PubMed

Wight, Megan; Chapparo, Christine

2008-12-01

Social competence has been linked to children's classroom performance with three out of four children with learning difficulties reported to have problems with social skills. Social participation remains a predominant childhood occupation and a key indicator of school performance. Occupational therapists work with teachers to accurately assess the social performance of children in context and to provide targeted intervention. There is limited research about what teachers perceive are the specific nature of social difficulties experienced by children with learning difficulties in the classroom. This study investigated teacher perceptions of the social competence of a small sample of Australian boys with learning difficulties within the classroom context. The Teacher Skillstreaming Checklist was used to investigate teacher perceptions of the social abilities of 21 primary school aged boys with learning difficulties compared to a control group. A correlational analysis was used to examine the relationship. The study identified that the boys with learning difficulties were perceived by their teachers as having poorer social performance across multiple domains when compared to their typically developing peers. Implications of these findings are that children's social performance may negatively impact learning and classroom participation and that for some children, social competence should be a focus of occupational therapy assessment and treatment.

This study examines sex differences in the risk threshold for adolescent delinquency. Analyses were based on longitudinal data from the Pittsburgh Youth Study (n = 503) and the Pittsburgh Girls Study (n = 856). The study identified risk factors, promotive factors, and accumulated levels of risks as predictors of delinquency and nondelinquency, respectively. The risk thresholds for boys and girls were established at two developmental stages (late childhood: ages 10–12 years, and adolescence: ages 13–16 years) and compared between boys and girls. Sex similarities as well as differences existed in risk and promotive factors for delinquency. ROC analyses revealed only small sex differences in delinquency thresholds, that varied by age. Accumulative risk level had a linear relationship with boys’ delinquency and a quadratic relationship with girls’ delinquency, indicating stronger effects for girls at higher levels of risk.

1991-01-01

A 9-year-old boy presented with a small subcutaneous tumor of the trunk and diffuse bone marrow involvement. The first histological diagnosis given was undifferentiated malignancy possibly of neural crest origin and chemotherapy was started immediately using vincristine, cyclophosphamide, cisplatin, and teniposide (OPEC). Complete response was achieved after four courses of chemotherapy. Histological slides were then reviewed and the final diagnosis of alveolar rhabdomyosarcoma (RMS) was retained. Moreover, chromosome analysis of malignant cells in the bone marrow revealed a translocation involving chromosomes 2 and 13:t(2;13) (q35;q14). This specific karyotype finding has been recently reported in a few cases and could be specific for alveolar RMS. The patient had a relapse 7 months after diagnosis and died 4 months later.

Conventional cytogenetics detected an interstitial deletion of proximal region of p-arm of chromosome 2 in a 6-month-old boy with a phenotype slightly resembling Down's syndrome. The deletion was inherited from the father, whose karyotype revealed a small ring-shaped marker chromosome, in addition to interstitial deletion. Fluorescence in situ hybridization identified the marker, which consisted of the proximal region of the p-arm of chromosome 2, including a part of its centromere. This case shows that molecular cytogenetic analysis can reveal the mechanism of the formation of the marker chromosome.

Little information is available regarding the status of insulin resistance (IR) and insulin deficiency (ID), as well as their relationship with obesity in children using the homeostasis model assessment (HOMA) in a population-based setting. The study included a total of 445 ninth-grade children participating in health check-up programs implemented in Tsunan Town, Niigata, Japan (boys/girls, 252/193 [participation rates: 98.1/95.5%]). HOMA of insulin resistance ≥2.5 was defined as IR, and HOMA of β-cell function <40 defined as ID. The medians (25-75th percentiles) of HOMA of insulin resistance, HOMA of β-cell function, Disposition Index and body mass index in boys were 1.2 (0.8-1.7), 64 (44-93), 52 (43-64) and 19.2 (18.0-20.7) kg/m 2 , respectively, vs 1.5 (1.0-2.0), 86 (63-120), 60 (50-74) and 20.4 (18.9-22.0) kg/m 2 , respectively, in girls. The HOMA of insulin resistance, HOMA of β-cell function and Disposition Index values were significantly higher in the girls (P = 0.002, P < 0.001 and P < 0.001, respectively). Those with IR accounted for a significantly higher proportion of girls than boys (15.5/8.7%; P = 0.027); those with obesity accounted for 9.9/10.7% (boys/girls); and those with IR and obesity accounted for 2.4/4.7%. Those with ID accounted for a significantly higher proportion of boys than girls (20.6/8.8%; P = 0.001), whereas those with ID and obesity accounted for a very small proportion of either group (0.4/0.5%). The presence of IR was higher among the girls. In contrast, ID was more frequent among the boys. The infrequent presence of ID among children might support the presence of non-obese type 2 diabetes adults in Japan. © 2017 The Authors.

This study aims to describe the time devoted to sedentary and physical activities at school in five European countries and to examine differences according to country, sex, ethnicity, parental education and weight status. cross-European cross-sectional survey. Primary schoolchildren (n=1025) aged 10-12 years in Belgium, Greece, Hungary, the Netherlands, and Switzerland wore accelerometers for at least six consecutive days. Only weekdays were used for this study to calculate the percentages of school-time spent in sedentary activities and moderate to vigorous intensity activity. Trained research assistants measured height and weight. Sex and date of birth were self-reported by the child and parental education and ethnicity were parent-reported. European schoolchildren spent on average 65% of their time at school in sedentary activities and 5% on moderate to vigorous intensity activities, with small differences between countries. Girls spent a significant larger amount of school-time in sedentary activities (67%) than boys (63%; p<0.0001), and spent less time in moderate to vigorous intensity activities (4% versus 5%; p<0.001). Overweight children spent significantly less time in moderate to vigorous intensity activities (4%) than normal weight children (5%,p < 0.01) [corrected]. Parental education or ethnicity were not associated with time spent in sedentary or physical activities. European schoolchildren spend a small amount of their school-time in moderate to vigorous intensity activities and a large amount in sedentary activities, with small but significant differences across countries. Future interventions should target more physical activities and less sedentary time at school particularly in girls. Copyright © 2013 Sports Medicine Australia. Published by Elsevier Ltd.

We examined whether there are sex differences in children's fruit and vegetable (FV) intake and in descriptive norms (i.e. perceived FV intake) related to parents and friends. We also studied whether friends' impact is as important as that of parents on children's FV intake. Data from the PRO GREENS project in Finland were obtained from 424 children at the age 11 years at baseline. At baseline, 2009 children filled in a questionnaire about descriptive norms conceptualised as perceived FV intake of their parents and friends. They also filled in a validated FFQ that assessed their FV intake both at baseline and in the follow-up in 2010. The associations were examined with multi-level regression analyses with multi-group comparisons. Girls reported higher perceived FV intake of friends and higher own fruit intake at baseline, compared with boys, and higher vegetable intake both at baseline and in the follow-up. Perceived FV intake of parents and friends was positively associated with both girls' and boys' FV intake in both study years. The impact of perceived fruit intake of the mother was stronger among boys. The change in children's FV intake was affected only by perceived FV intake of father and friends. No large sex differences in descriptive norms were found, but the impact of friends on children's FV intake can generally be considered as important as that of parents. Future interventions could benefit from taking into account friends' impact as role models on children's FV intake.

To use ecological momentary assessment to describe how adolescent boys in the United Kingdom spend their leisure time. Design. Cross-sectional, stratified, random sample from secondary schools in 15 regions within the United Kingdom. The data are from a larger study of adolescent lifestyles (Project STIL). A total of 561 boys with a mean age of 14.6 years (range 12.7-16.7 years). The majority were white-European (86.5%). Television viewing occupied the most leisure time on both weekdays (131 minutes) and weekend (202.5 minutes) days. On weekdays the five most time consuming sedentary activities (television viewing, homework, motorised travel, playing computer/video games and shopping/hanging out) occupied on average 272.2 minutes. On weekend days, the five most time consuming sedentary activities (television viewing, shopping/hanging out, motorised travel, sitting and talking and playing computer/video games) occupied 405.5 minutes. In total, 54 minutes were occupied by active transport or sports and exercise per weekday and 81 minutes per weekend day. Only a minority watched more than 4 hours of TV per day (8.9% on weekdays and 33.8% on weekend days). Differences were noted in the means and prevalence between weekend and weekdays, reflecting the greater discretionary time available at the weekend. Adolescent boys engage in a variety of sedentary and active free time behaviours. It appears prudent to encourage adolescents to adopt overall healthy lifestyles by considering the combination of both active and sedentary pursuits an individual engages in and by moving beyond a focus on any one single behaviour.

Adolescent Susceptibility to Peer Influence in Sexual Situations

2016-01-01

Purpose One consistent predictor of adolescents’ engagement in sexual risk behavior is their belief that peers are engaging in similar behavior; however, not all youth are equally susceptible to these peer influence effects. Understanding individual differences in susceptibility to peer influence is critical to identifying adolescents at risk for negative health outcomes. The purpose of this project was to identify predictors of susceptibility to peer influence using a novel performance-based measure of sexual risk-taking. Methods Participants were 300 early adolescents (Mage=12.6; 53% female; 44% Caucasian) who completed 1) a pretest assessment of demographics, sexual attitudes, and hypothetical scenarios measuring the likelihood of engaging in sexual risk behavior, and 2) a subsequent experimental procedure that simulated an internet chat room in which youth believed they were communicating with peers regarding these same hypothetical scenarios. In reality, these “peers” were computer-programmed e-confederates. Changes in responses to the sexual scenarios in the private pretest versus during the public chat room provided a performance-based measure of peer influence susceptibility. Results In total, 78% of youth provided more risky responses in the chat room than in pretest. The most robust predictor of this change was gender, with boys significantly more susceptible to peer influence than girls. Significant interactions also were noted, with greater susceptibility among boys with later pubertal development and African American boys. Conclusion Results confirm that not all youth are equally susceptible to peer influence. Consistent with sexual script theory, boys evidence greater susceptibility to social pressure regarding sexual behavior than girls. PMID:26794431

Developmental Neurogenetics and Multimodal Neuroimaging of Sex Differences in Autism

Chen, Christina; Van Horn, John Darrell

2016-01-01

Examining sex differences in the brain has been contentious but is nonetheless important for advancing mental health for both girls and boys. Unfortunately, females in biomedical research remain underrepresented in most mental health conditions including autism spectrum disorders (ASD), even though equal inclusion of females would improve treatment for girls and yield benefits to boys. This review examines sex differences in the relationship between neuroanatomy and neurogenetics of ASD. Recent findings reveal that girls diagnosed with ASD exhibit more intellectual and behavioral problems compared to their male counterparts, suggesting that girls may be less likely diagnosed in the absence of such problems or that they require a higher mutational load to meet the diagnostic criteria. Thus far, the female biased effect of chromosome 4, 5p15.33, 8p, 9p24.1, 11p12-13, 15q, and Xp22.3 and the male biased effect of 1p31.3, 5q12.3, 7q, 9q33.3, 11q13.4, 13q33.3, 16p11.2, 17q11-21, Xp22.33/Yp11.31, DRD1, NLGN3, MAOA, and SHANK1 deletion have been discovered in ASD. The SNPs of genes such as RYR2, UPP2, and the androgen receptor gene have been shown to have sex-biasing factors in both girls and boys diagnosed with ASD. These sex-related genetic factors may drive sex differences in the neuroanatomy of these girls and boys, including abnormal enlargement in temporal gray and white matter volumes, and atypical reduction in cerebellar gray matter volumes and corpus callosum fibers projecting to the anterior frontal cortex in ASD girls relative to boys. Such factors may also be responsible for the attenuation of brain sexual differentiation in adult men and women with ASD; however, much remains to be uncovered or replicated. Future research should leverage further the association between neuroanatomy and genetics in girls for an integrated and interdisciplinary understanding of ASD. PMID:26781567

This paper examines the long-term impacts on health and healthy behaviors of two of the oldest and most widely cited U.S. early childhood interventions evaluated by the method of randomization with long-term follow-up: the Perry Preschool Project (PPP) and the Carolina Abecedarian Project (ABC). There are pronounced gender effects strongly favoring boys, although there are also effects for girls. Dynamic mediation analyses show a significant role played by improved childhood traits, above and beyond the effects of experimentally enhanced adult socioeconomic status. These results show the potential of early life interventions for promoting health. PMID:28260805

Hmong women, opium cultivation and livestock production in Lao PDR.

PubMed

Oparaocha, S

1998-01-01

This article analyzes the effects on Hmong women of a Laotian government policy to replace production of opium by upland farmers with other cash crops by the year 2000. In 1996, 15% of the population relied on opium as a cash crop. This project aimed to include Hmong women in small livestock production in 2 villages: Ban Kampanien and Ban Pha Ven in Nong Het district, Xieng Khouang province, near the Vietnamese border. Interviews were conducted among 33 families using the Harvard Gender Analytical Tools (1991) to determine gender roles in livestock production. Participatory assessment relied on matrix ranking, resource maps, and trend charts. In Nong Het, White Hmong dominate. Average family size is 7 persons. Polygamy is allowed, but declining. The birthrate is high. Swidden agriculture is practiced. Agricultural production meets demand. Patriarchal authority dominates; men and women have separate public and private spheres. Education favors boys. Women are involved in all aspects of agricultural production. The author describes women's role in small livestock production and gender roles in feed management. Women exercise autonomy only through raising livestock and poultry. Women's production is constrained by limited access to extension services, feed resources, labor saving technology, and credit. In order to offset the loss of income from opium, Hmong women need to increase their income by increasing the product output per animal using selective breeding, and decreasing time spent on preparing and processing food. Assistance should be provided to improve women's resources and knowledge.

2008-07-01

This paper reports two prospective investigations of the role of friendship in the relation between peer victimization and grade point averages (GPA). Study 1 included 199 children (105 boys, 94 girls; mean age of 9.1 years) and Study 2 included 310 children (151 boys, 159 girls; mean age of 8.5 years). These children were followed for two school years. In both projects, we assessed aggression, victimization, and friendship with a peer nomination inventory, and we obtained children's GPAs from a review of school records. Peer victimization was associated with academic declines only when children had either a high number of friends who were above the classroom mean on aggression or a low number of friends who were below the classroom mean on aggression. These results highlight the importance of aggression levels among friends for the academic adjustment of victimized children.

Expect Respect, a teen dating violence prevention program, was among four programs selected by the Centers for Disease Control and Prevention to participate in an empowerment evaluation project. As one aspect of this project, a qualitative study was designed to investigate the effects of Expect Respect support groups for at-risk youth. The goal was to understand the "how and why" of the program's impact on participants. Group interviews were conducted with five boys' and five girls' support groups after completion of the program. Settings included public middle and high schools and alternative schools in juvenile detention. Participants were asked to describe significant learning experiences in support groups as well as changes in their relationships resulting from program participation. Youths across all groups reported learning new skills including improved communication, anger control, and alternatives to violence. They reported increased knowledge about healthy relationships and warning signs of dating violence and expanded awareness of their own and others' abusive behaviors. Changed relationship norms were uniquely expressed by a boys' group in juvenile detention. Findings indicate that the experience of emotional safety in groups and positive relationships among group members were instrumental in the learning process.

In addition to genetic predispositions and environmental factors, healthy lifestyle education is very important for children and adolescents. The purpose of this research was to estimate the number of overweight and obese children and adolescents from small towns and villages and to find out an association between health awareness in children and the risk of becoming overweight or obese. The research was conducted in 1,515 healthy children aged 6-18 years from small towns and villages in Poland. Overweight was diagnosed when BMI for age and sex was over the 90th percentile; obesity--when it was over the 95th percentile. The study consisted of a lifestyle interview and anthropometrical measurements. The lifestyle interview was conducted with the use of an anonymous questionnaire form and included questions about food frequency, diet habits and physical activity. The research was analysed using the SAS System for Windows, release 8.02. Overweight status was diagnosed in 9.0% and obesity in 5.1% of respondents. Excess body mass was statistically more frequently diagnosed in girls than in boys aged 14-18 years. Girls of this age group significantly more frequently chose wholemeal bread, smoked sausages, meat and poultry as products that are believed to keep them fit. Older children substantially more often indicated that stress, smoking cigarettes, consuming fatty meat, sweets, being obese, and a lack of physical activity are factors that damage health. Boys spent more time in front of a computer or TV than girls; in the older group of children, the phenomenon even intensified. Awareness of healthy lifestyle behaviour is not sufficient to maintain optimal body mass. Knowledge about proper eating habits is better among girls than among boys, especially in the older age groups. However, in older groups, there was less physical activity due to spending more time in front of TV or the computer. High percentage of obese/overweight children and insufficient knowledge of nutrition may consequently result in increased risk of cardio-vascular diseases in adult population.

Urinary tract infection (UTI) is a common bacterial disease in small children in which treatment with antimicrobials is used. The worldwide increase of bacterial resistance to these drugs is threatening the efficacy of such treatment and may increase the risk for long-term damage. The aim of this retrospective study was to analyse the development of resistance to oral antimicrobials over a 10-year period in an unselected outpatient population of small children with first-time UTI. The patient material included 494 boys and 512 girls below 2 years of age with community acquired symptomatic UTI. Escherichia coli bacteria were isolated in 96 % of girls and 89 % of boys (p < 0.0001). The overall resistance of E. coli was 14 % to trimethoprim and below 1 % to cefadroxil and nitrofurantoin. Over the 10-year period, the trimethoprim resistance of E. coli increased from 5 to 17 % but remained unchanged to cefadroxil and nitrofurantoin. E. coli resistance to trimethoprim was related to age: 11 % below and 19 % above 9 months (p < 0.01). The increase in resistance over time and with age was found only in girls. The increasing resistance of E. coli to trimethoprim makes this drug less suitable for empiric treatment of UTI. Young children with UTI seem predisposed to early development of resistance. Therefore, surveillance of resistance to antimicrobials with special regard to age and gender is recommended.

What clinical practices, patient management strategies and experimental methods are currently being used to preserve and restore the fertility of prepubertal boys and adolescent males? Based on a review of the clinical literature and research evidence for sperm freezing and testicular tissue cryopreservation, and after consideration of the relevant ethical and legal challenges, an algorithm for the cryopreservation of sperm and testicular tissue is proposed for prepubertal boys and adolescent males at high risk of fertility loss. A known late effect of the chemotherapy agents and radiation exposure regimes used to treat childhood cancers and other non-malignant conditions in males is the damage and/or loss of the proliferating spermatogonial stem cells in the testis. Cryopreservation of spermatozoa is the first line treatment for fertility preservation in adolescent males. Where sperm retrieval is impossible, such as in prepubertal boys, or it is unfeasible in adolescents prior to the onset of ablative therapies, alternative experimental treatments such as testicular tissue cryopreservation and the harvesting and banking of isolated spermatogonial stem cells can now be proposed as viable means of preserving fertility. Advances in clinical treatments, patient management strategies and the research methods used to preserve sperm and testicular tissue for prepubertal boys and adolescents were reviewed. A snapshot of the up-take of testis cryopreservation as a means to preserve the fertility of young males prior to December 2012 was provided using a questionnaire. A comprehensive literature review was conducted. In addition, survey results of testis freezing practices in young patients were collated from 24 European centres and Israeli University Hospitals. There is increasing evidence of the use of testicular tissue cryopreservation as a means to preserve the fertility of pre- and peri-pubertal boys of up to 16 year-old. The survey results indicate that of the 14 respondents, half of the centres were actively offering testis tissue cryobanking as a means of safeguarding the future fertility of boys and adolescents as more than 260 young patients (age range less than 1 year old to 16 years of age), had already undergone testicular tissue retrieval and storage for fertility preservation. The remaining centres were considering the implementation of a tissue-based fertility preservation programme for boys undergoing oncological treatments. The data collected were limited by the scope of the questionnaire, the geographical range of the survey area, and the small number of respondents. The clinical and research questions identified and the ethical and legal issues raised are highly relevant to the multi-disciplinary teams developing treatment strategies to preserve the fertility of prepubertal and adolescent boys who have a high risk of fertility loss due to ablative interventions, trauma or genetic pre-disposition. © The Author 2015.

2013-07-01

Emotion expression is an important feature of healthy child development that has been found to show gender differences. However, there has been no empirical review of the literature on gender and facial, vocal, and behavioral expressions of different types of emotions in children. The present study constitutes a comprehensive meta-analytic review of gender differences and moderators of differences in emotion expression from infancy through adolescence. We analyzed 555 effect sizes from 166 studies with a total of 21,709 participants. Significant but very small gender differences were found overall, with girls showing more positive emotions (g = -.08) and internalizing emotions (e.g., sadness, anxiety, sympathy; g = -.10) than boys, and boys showing more externalizing emotions (e.g., anger; g = .09) than girls. Notably, gender differences were moderated by age, interpersonal context, and task valence, underscoring the importance of contextual factors in gender differences. Gender differences in positive emotions were more pronounced with increasing age, with girls showing more positive emotions than boys in middle childhood (g = -.20) and adolescence (g = -.28). Boys showed more externalizing emotions than girls at toddler/preschool age (g = .17) and middle childhood (g = .13) and fewer externalizing emotions than girls in adolescence (g = -.27). Gender differences were less pronounced with parents and were more pronounced with unfamiliar adults (for positive emotions) and with peers/when alone (for externalizing emotions). Our findings of gender differences in emotion expression in specific contexts have important implications for gender differences in children's healthy and maladaptive development. 2013 APA, all rights reserved

This study examined the impact of a targeted Irish early intervention program on children’s emotional and behavioral development using multiple methods to test the robustness of the results. Data on 164 Preparing for Life participants who were randomly assigned into an intervention group, involving home visits from pregnancy onwards, or a control group, was used to test the impact of the intervention on Child Behavior Checklist scores at 24-months. Using inverse probability weighting to account for differential attrition, permutation testing to address small sample size, and quantile regression to characterize the distributional impact of the intervention, we found that the few treatment effects were largely concentrated among boys most at risk of developing emotional and behavioral problems. The average treatment effect identified a 13% reduction in the likelihood of falling into the borderline clinical threshold for Total Problems. The interaction and subgroup analysis found that this main effect was driven by boys. The distributional analysis identified a 10-point reduction in the Externalizing Problems score for boys at the 90th percentile. No effects were observed for girls or for the continuous measures of Total, Internalizing, and Externalizing problems. These findings suggest that the impact of this prenatally commencing home visiting program may be limited to boys experiencing the most difficulties. Further adoption of the statistical methods applied here may help to improve the internal validity of randomized controlled trials and contribute to the field of evaluation science more generally.

The aim of this study was to explore the effect of the Active Teen Leaders Avoiding Screen-time (ATLAS) intervention on psychological well-being in adolescent boys and to examine the potential mediating mechanisms that might explain this effect. ATLAS was evaluated using a cluster randomized controlled trial in 14 secondary schools located in low-income communities (N = 361 adolescent boys, mean age = 12.7 ± .5 years). The 20-week intervention was guided by self-determination theory and involved: professional development for teachers, provision of fitness equipment to schools, enhanced school sport sessions, researcher-led seminars, a smartphone application, and parental strategies for reducing screen time. Assessments were conducted at baseline and immediately post intervention (8 months). Psychological well-being was measured using the Flourishing Scale. Motivational regulations (intrinsic, identified, introjected, controlled, and amotivation) and basic psychological needs (autonomy, competence, and relatedness) in school sport, muscular fitness, resistance training skill competency, and recreational screen time were examined as potential mediating mechanisms of the intervention effect. The intervention effect on well-being was small but statistically significant. Within a multiple mediator model, changes in autonomy needs satisfaction, recreational screen time, and muscular fitness significantly mediated the effect of the intervention on psychological well-being. In addition to the physical health benefits, targeted physical activity programs for adolescent boys may have utility for mental health promotion through the mechanisms of increasing autonomy support and muscular fitness and reducing screen time.

Girls and women in the general population present with a distinct profile of clinical needs and use more associated health services compared to boys and men; however, research focused on health service use patterns among girls and women with Autism Spectrum Disorder (ASD) is limited. In the current study, caregivers of 61 adolescent girls and women with ASD and 223 boys and men with ASD completed an online survey. Descriptive analyses were conducted to better understand the clinical needs and associated service use patterns of girls and women with ASD. Sex/gender comparisons were made of individuals' clinical needs and service use. Adolescent girls and women with ASD had prevalent co-occurring mental and physical conditions and parents reported elevated levels of caregiver strain. Multiple service use was common across age groups, particularly among adolescent girls and women with intellectual disability. Overall, few sex/gender differences emerged, although a significantly greater proportion of girls and women accessed psychiatry and emergency department services as compared to boys and men. Though the current study is limited by its use of parent report and small sample size, it suggests that girls and women with ASD may share many of the same high clinical needs and patterns of services use as boys and men with ASD. Areas for future research are discussed to help ensure appropriate support is provided to this understudied population.

The potential dissociation between muscle strength and size has led to interest in the ability to assess muscle quality across the lifespan. We examined the association between echo intensity and specific tension in middle-school boys. Twenty-five boys participated in this study. Sixteen (mean  ±  SD age  =  12  ±  1 years) engaged in a 16-week after-school strength and conditioning program. Nine boys (12  ±  1 years) served as controls. The program involved two 90 min sessions per week of lower-body speed, power, and resistance training. Before and after the intervention, ultrasound imaging was used to quantify vastus lateralis and rectus femoris echo intensity. Specific tension was calculated as voluntary isometric peak torque divided by dual energy x-ray absorptiometry-derived thigh lean mass (Nm kg -1 ). The pretest echo intensity and specific tension data were not significantly correlated (r  =  0.040, p  =  0.850). Training resulted in a small mean increase in specific tension (change  =  1.93 Nm kg -1 ; d  =  0.42). The echo intensity values were not affected by training or maturation (training change  =  -1.13 arbitrary units (A.U.); control  =  0.00 A.U.). Both variables showed no interaction and no group or time main effects. The echo intensity and specific tension change scores were not correlated for all subjects (r  =  -0.080, p  =  0.705) or groups (training r  =  -0.095, p  =  0.727; control r  =  -0.004, p  =  0.992). In middle-school boys, a relationship between echo intensity and the ratio of muscle strength relative to lean mass does not exist.

Achievement Place: experiments in self-government with pre-delinquents.

One of the goals of many treatment programs for pre-delinquent youths is the development of the skills involved in the democratic decision-making process. At Achievement Place, one aspect of the treatment program is a semi-self-government system whereby the seven pre-delinquent youths can democratically establish many of their own rules of behavior, monitor their peers' behavior to detect violations of their rules, and conduct a "trial" to determine a rule violator's guilt or innocence, and to determine the consequences for a youth who violates a rule. Two experiments were carried out to determine the role of some of the procedures in the boys' participation in the self-government system. Experiment I showed that more boys participated in the discussion of consequences for a rule violation when they had complete responsibility for setting the consequence during the trials than when the teaching-parents set the consequence for each rule violation before the trial. An analysis of the rule violations in this experiment indicated that the boys in Achievement Place reported more of the rule violations that resulted in trials than reported by the teaching-parents or school personnel. The boys reported rule violations that occurred in the community and school as well as at Achievement Place, including most of the serious rule violations that came to the attention of the teaching-parents. In Experiment II, the results indicated that more trials were called when the teaching-parents were responsible for calling trials on rule violations reported by the peers than when the boys were responsible for calling trials. When the youths earned points for calling trials the average number of trials per day increased, but more trivial rule violations were reported. These results suggest that aspects of the democratic decision-making process in a small group of pre-delinquents can be studied and variables that affect participation can be identified and evaluated.

Introduction The study involved preparing and implementation a model of complex screening programme for adolescents and comparison of anthropometric examinations between the population of the SOPKARD-Junior programme and representative sample of Polish children in the same age. Material and methods The screening programme in 14–15 year old pupils (n = 282) included: anthropometric, blood pressure, echocardiographic, electrocardiographic, carotid arteries, kidney and thyroid ultrasound examinations, as well as respiratory, dental and masticatory system, orthopaedic, psychological and psychiatric assessment. Blood and urine tests were also performed. The results of anthropometric examinations from the SOPKARD-Junior and OLAF programmes were used for comparative analysis. Results Statistically significant (p < 0.001) differences between young people from Sopot and their peers in the general Polish population were found in height (+3.61 cm for boys), body mass (+5.19 kg for boys and +3.99 kg for girls), body mass index (+0.99 kg/m2 for boys and +1.33 kg/m2 for girls), waist circumference (+4.52 cm for boys and +4.52 cm for girls) and hip circumference (+2.51 cm for boys). The highest attendance rate was achieved for examinations performed in school (e.g. anthropometric and blood pressure measurements – n = 268; 95%) and the lowest for the echocardiograpy performed in local hospital (n = 133; 47%). The mean score of the programme quality (scale 1–6) assessed by children was 4.63. Conclusions The SOPKARD-Junior programme represents an attempt to develop a model of screening assessments for teenagers in Poland. Preliminary results of the SOPKARD-Junior programme indicate small differences in the biological development of Sopot youth in comparison with their peers from Polish population of the OLAF programme. The high attendance rate on research conducted at the school indicate that proposed health examinations in adolescents are acceptable and feasible. PMID:29379531

The objective of this study is to estimate the relative contribution of biological maturation to variance in the motor coordination (MC) among youth and to explore gender differences in the associations. Skeletal maturation (Tanner-Whitehouse 3), stature, body mass, and MC (Körperkoordinationstest für Kinder) were assessed in 613 youths, 284 boys and 329 girls 11-14 yr of age. Standardized residuals of skeletal age on chronological age were used as the estimate of skeletal maturity status independent of chronological age. Hierarchical multiple regression analyses were used to analyse associations between skeletal maturity status and MC. Skeletal maturity status by itself, i.e., standardized residuals of skeletal age on chronological age (step 3) explained a maximum of 8.1% of the variance in MC in boys (ΔR3 in the range of 0.0%-8.1%) and 2.8% of the variance in girls (ΔR3 in the range of 0.0%-2.8%), after controlling for stature, body mass and interactions of the standardized residuals of skeletal age on chronological age with stature and body mass. Corresponding percentages for the interactions of the standardized residuals of skeletal age and stature and body mass, after adjusting for stature and body mass (step 2) were 8.7% in boys (ΔR2 in the range of 0.3%-8.7%) and 7.1% in girls (ΔR2 in the range of 0.1%-7.1%). Chow tests suggested structural changes in β-coefficients in the four MC tests among boys and girls, 12-13 yr. The percentage of variance in the four MC tests explained by skeletal maturation was relatively small, but the relationships differed between boys and girls. By inference, other factors, e.g., neuromuscular maturation, specific instruction and practice, sport participation, and others may influence MC at these ages.

After a concussion, guidelines emphasize that an athlete should be asymptomatic before starting a return-to-play protocol. However, many concussion symptoms are nonspecific and may be present in individuals without concussion. Limited evidence exists regarding the presence of "typical" or preinjury (baseline) symptoms in child and youth athletes. To describe the frequency of symptoms reported at baseline by child and youth athletes and identify how age, sex, history of concussion, and learning factors influence the presence of baseline symptoms. Cross-sectional cohort study. Baseline testing was conducted at a hospital research laboratory or in a sport or school setting (eg, gym or arena). A total of 888 child (9-12 years old, n = 333) and youth (13-17 years old, n = 555) athletes participated (46.4% boys and 53.6% girls, average age = 13.09 ± 1.83 years). Demographic and symptom data were collected as part of a baseline protocol. Age-appropriate versions of the Post-Concussion Symptom Inventory (a self-report concussion-symptoms measure with strong psychometric properties for pediatric populations) were administered. Demographic data (age, sex, concussion history, learning factors) were also collected. Common baseline symptoms for children were feeling sleepier than usual (30% boys, 24% girls) and feeling nervous or worried (17% boys, 25% girls). Fatigue was reported by more than half of the youth group (50% boys, 67% girls). Nervousness was reported by 32% of youth girls. Headaches, drowsiness, and difficulty concentrating were each reported by 25% of youth boys and girls. For youths, a higher total symptom score was associated with increasing age and number of previous concussions, although these effects were small (age r s = 0.143, number of concussions r s = .084). No significant relationships were found in the child group. Children and youths commonly experienced symptoms at baseline, including fatigue and nervousness. Whether clinicians should expect complete symptom resolution after concussion is not clear.

An 11 year-old-boy acutely developed complex visual and acoustic hallucinations. Hallucinations, consisting of visions of a threatening, evil character of the Harry Potter saga, persisted for 3 days. Neurological and psychiatric examinations were normal. Ictal EEG was negative. MRI documented 3 small areas of hyperintense signal in the brainstem, along the paramedian and lateral portions of pontine tegmentum, one of which showed post-contrast enhancement. These lesions were likely of inflammatory origin, and treatment with immunoglobulins was started. Polysomnography was normal, multiple sleep latency test showed a mean sleep latency of 8 minutes, with one sleep-onset REM period. The pontine tegmentum is responsible for REM sleep regulation, and contains definite "REM-on" and "REM-off" regions. The anatomical distribution of the lesions permits us to hypothesize that hallucinations in this boy were consequent to a transient impairment of REM sleep inhibitory mechanisms, with the appearance of dream-like hallucinations during wake.

This study analyzed the psychometric properties of scores on the Slovene version of the Questionnaire about Interpersonal Difficulties for Adolescents (QIDA) in a sample of 1,334 adolescents (44% boys), ranging in age from 12 to 18 years (M = 15.61). Confirmatory factor analyses replicated the correlated five-factor structure of the QIDA: Assertiveness, Heterosexual Relationships, Public Speaking, Family Relationships, and Close Friendships. Internal consistency and test-retest reliability were reasonable. Correlations of scores on the QIDA with scores of neuroticism, low extraversion, and low openness, as measured by the Inventory of Child/Adolescent Individual Differences, and scores of fear of negative evaluation, and tension and inhibition in social contacts, as measured by the Social Anxiety Scale for Adolescents were found, revealing differential links with QIDA subscale scores. Girls reported more difficulties than boys. Age differences showed a small but significant decrease in QIDA total score over adolescence.

Managing Small Spacecraft Projects: Less is Not Easier

Managing small, low cost missions (class C or D) is not necessarily easier than managing a full flagship mission. Yet, small missions are typically considered easier to manage and used as a training ground for developing the next generation of project managers. While limited resources can be a problem for small missions, in reality most of the issues inherent in managing small projects are not the direct result of limited resources. Instead, problems encountered by managers of small spacecraft missions often derive from 1) the perception that managing small projects is easier if something is easier it needs less rigor and formality in execution, 2) the perception that limited resources necessitate or validate omitting standard management practices, 3) less stringent or unclear guidelines or policies for small projects, and 4) stakeholder expectations that are not consistent with the size and nature of the project. For example, the size of a project is sometimes used to justify not building a full, detailed integrated master schedule. However, while a small schedule slip may not be a problem for a large mission, it can indicate a serious problem for a small mission with a short development phase, highlighting the importance of the schedule for early identification of potential issues. Likewise, stakeholders may accept a higher risk posture early in the definition of a low-cost mission, but as launch approaches this acceptance may change. This presentation discusses these common misconceptions about managing small, low cost missions, the problems that can result, and possible solutions.

Gender gap in parents' financing strategy for hospitalization of their children: evidence from India.

The 'missing women' dilemma in India has sparked great interest in investigating gender discrimination in the provision of health care in the country. No studies, however, have directly examined discrimination in health-care financing strategies in the case of severe illness of sons versus daughters. In this paper, we hypothesize that households who face tight budget constraints are more likely to spend their meager resources on hospitalization of boys rather than girls. We use the 60th round of the Indian National Sample Survey (2004) and a multinomial logit model to test this hypothesis and to throw some light on this important but overlooked issue. The results reveal that boys are much more likely to be hospitalized than girls. When it comes to financing, the gap in the usage of household income and savings is relatively small, while the gender gap in the probability of hospitalization and usage of more onerous financing strategies is very high. Ceteris paribus, the probability of boys to be hospitalized by financing from borrowing, sale of assets, help from friends, etc. is much higher than that of girls. Moreover, in line with our theoretical framework, the results indicate that the gender gap intensifies as we move from the richest to poorest households. (c) 2009 John Wiley & Sons, Ltd.

Few qualitative studies have explored adolescent boys’ perceptions of health. Aim: The aim of this study was therefore to explore how adolescent boys understand the concept of health and what they find important for its achievement Methods: Grounded theory was used as a method to analyse interviews with 33 adolescent boys aged 16 to 17 years attending three upper secondary schools in a relatively small town in Sweden. Results: There was a complexity in how health was perceived, experienced, dealt with, and valued. Although health on a conceptual level was described as ‘holistic’, health was experienced and dealt with in a more dualistic manner, one in which the boys were prone to differentiate between mind and body. Health was experienced as mainly emotional and relational, whereas the body had a subordinate value. The presence of positive emotions, experiencing self-esteem, balance in life, trustful relationships, and having a sense of belonging were important factors for health while the body was experienced as a tool to achieve health, as energy, and as a condition. Conclusion: Our findings indicate that young, masculine health is largely experienced through emotions and relationships and thus support theories on health as a social construction of interconnected processes.

Testicular tissue cryopreservation and spermatogonial stem cell transplantation to restore fertility: from bench to bedside

PubMed Central

2014-01-01

Male infertility management has made significant progress during the past three decades, especially after the introduction of intracytoplasmic sperm injection in 1992. However, many boys and men still suffer from primary testicular failure due to acquired or genetic causes. New and novel treatments are needed to address these issues. Spermatogenesis originates from spermatogonial stem cells (SSCs) that reside in the testis. Many of these men lack SSCs or have lost SSCs over time as a result of specific medical conditions or toxic exposures. Loss of SSCs is critical in prepubertal boys who suffer from cancer and are going through gonadotoxic cancer treatments, as there is no option of sperm cryopresrvation due to sexual immaturity. The development of SSC transplantation in a mouse model to repopulate spermatozoa in depleted testes has opened new avenues of research in other animal models, including non-human primates. Recent advances in cryopreservation and in vitro propagation of human SSCs offer promise for human SSC autotransplantation in the near future. Ongoing research is focusing on safety and technical issues of human SSC autotransplantation. This is the time to counsel parents and boys at risk of infertility on the possibility of cryopreserving and banking a small amount of testis tissue for potential future use in SSC transplantation.

Preventing urinary tract infections in early childhood.

PubMed

Williams, Gabrielle J; Craig, Jonathan C; Carapetis, Jonathan R

2013-01-01

Urinary tract infection (UTI) is common in children, causes them considerable discomfort, as well as distress to parents and has a tendency to recur. Approximately 20% of those children who experience one infection will have a repeat episode. Since 1975, 11 trials of long-term antibiotics compared with placebo or no treatment in 1,550 children have been published. Results have been heterogeneous, but the largest trial demonstrated a small reduction (6% absolute risk reduction, risk ratio 0.65) in the risk of repeat symptomatic UTI over 12 months of treatment. This effect was consistent across sub groups of children based upon age, gender, vesicoureteric reflux status and number of prior infections. Trials involving re-implantation surgery (and antibiotics compared with antibiotics alone) for the sub-group of children with vesicoureteric reflux have not shown a reduction in repeat UTI, with the possible exception of a very small benefit for febrile UTI. Systematic reviews have shown that circumcision reduces the risk of repeat infection but 111 circumcisions would need to be performed to prevent one UTI in unpredisposed boys. Given the need for anaesthesia and the risk of surgical complication, net clinical benefit is probably restricted to those who are predisposed (such as those with recurrent infection). Many small trials in complementary therapies have been published and many suggest some benefit, however inclusion of children is limited. Only three trials involving 394 children for cranberry products, two trials with a total of 252 children for probiotics and one trial with 24 children for vitamin A are published. Estimates of efficacy vary widely and imprecision is evident. Multiple interventions to prevent UTI in children exist. Of those, long-term low dose antibiotics has the strongest evidence base, but the benefit is small. Circumcision in boys reduces the risk substantially, but should be restricted to those at risk. There is little evidence of benefit of re-implantation alone, and the benefit of this procedure over antibiotics alone is very small. Cranberry concentrate is probably effective.

Blue-ringed octopus (Hapalochlaena sp.) envenomation of a 4-year-old boy: a case report.

PubMed

Cavazzoni, Elena; Lister, Bruce; Sargent, Phillip; Schibler, Andreas

2008-09-01

The blue-ringed octopus (Hapalochlaena sp.) is a small animal, which can inject a toxin that produces a respiratory arrest within minutes. This envenomation is a rare occurrence with very few reported outcomes in children. A 4-year-old boy was bitten by a blue-ringed octopus (Hapalochlaena sp.) whilst playing at a popular beach in Queensland, Australia. Within ten minutes of the bite, he had vomited three times, lost the ability to stand and complained of blurred vision. An ambulance was called by the time he presented to the local emergency department (20 minutes after the bite) he had acute and progressive skeletal muscle weakness. He was intubated, ventilated, and transferred to a pediatric intensive care unit for specialized supportive care. He was ventilated for a total of 17 hours with spontaneous muscular activity returning at around 15 hours from envenomation. If not treated appropriately the bite of this small and innocuous looking animal could have lead to death within minutes. This case report serves as a reminder of how appropriate treatment can ensure discharge from hospital with no long-term consequences. It also highlights the importance of education for beach goers and in particular parents to prevent exposure of tetrodotoxin to children.

[Bladder stones in children in Gabon. Three case reports].

Bladder stones are uncommon in children in Gabon. The authors report the case of 3 boys admitted to the Paediatric Hospital of Owendo for voiding disorders. All patients came from the South of the country, but these stones cannot be described as endemic in view of the small number of cases. The authors recall the main aetiologies, the suggestive symptoms and the simple and inexpensive complementary investigations (plain abdominal x-ray and ultrasonography) allowing the definitive diagnosis. Conventional surgical treatment gives good results, but in the case of small stones, endourological treatment can be more economical in terms of the duration of hospital stay and postoperative morbidity.

Congenital hypogonadotropic hypogonadism, functional hypogonadotropism or constitutional delay of growth and puberty? An analysis of a large patient series from a single tertiary center.

What diagnoses underlie delayed puberty (DP) and predict its outcome? A multitude of different diagnoses underlie DP, and in boys a history of cryptorchidism, small testicular size and slow growth velocity (GV) predict its clinical course. DP is caused by a variety of underlying etiologies. Hormonal markers can be used in the differential diagnosis of DP but none of them have shown complete diagnostic accuracy. Medical records of 589 patients evaluated for DP in a single tertiary care center between 2004 and 2014 were retrospectively reviewed. Clinical and biochemical data of 174 boys and 70 girls who fulfilled the criteria of DP were included in the analyses. We characterized the frequencies of underlying conditions and evaluated the predictive efficacy of selected clinical and hormonal markers. Thirty etiologies that underlie DP were identified. No markers of clinical value could be identified in the girls, whereas a history of cryptorchidism in the boys was associated with an increase in the risk of permanent hypogonadism (odds ratio 17.2 (95% CI; 3.4-85.4, P < 0.001)). The conditions that cause functional hypogonadotropic hypogonadism were more frequent in boys with a GV below 3 cm/yr than in those growing faster (19% vs 4%, P < 0.05). In this series, the most effective markers to discriminate the prepubertal boys with constitutional delay of growth and puberty (CDGP) from those with congenital hypogonadotropic hypogonadism (CHH) were testicular volume (cut-off 1.1 ml with a sensitivity of 100% and a specificity of 91%), GnRH-induced maximal LH (cut-off 4.3 IU/L; 100%, 75%) and basal inhibin B (INHB) level (cut-off 61 ng/L; 90%, 83%). The main limitation of the study is the retrospective design. Prior cryptorchidism and slow GV are two important clinical cues that may help clinicians to predict the clinical course of DP in boys, whereas markers of similar value could not be identified in girls. In prepubertal boys, testicular size appeared as effective as INHB and GnRH-induced LH levels in the differential diagnosis between CHH and CDGP.

The purpose of this study was to examine the effectiveness of a 30-week fundamental motor skill program in typically developing young children and to investigate possible sex differences. A multicenter quasi experimental design was set up for this study which involved 992 children aged 3-8 years. All participants received their typical Physical Education curriculum and habitual movement activities. The intervention group (n=523; 53.5% boys) received a weekly 60-min motor skill session provided by trained local instructors in existing child settings; the control group (n=469; 49.7% boys) received no additional practice. Fundamental motor skills were assessed using the Test of Gross Motor Development, 2nd Edition before and after the intervention. To assess the effect of the intervention and possible sex differences, hierarchical linear regressions analyses were conducted for locomotor and object control gain scores. The intervention group demonstrated a higher gain in both locomotor (β=3.78, SE=1.08, p<0.001) and object control (β=4.46, SE=1.06, p<0.001) skills than the control group. Girls demonstrated a lower gain in object control skills (β=-3.50, SE=0.49, p<0.001) and higher gain in locomotor skills (β=1.01, SE=0.44, p=0.022) than boys, regardless of group. The present study demonstrated the effectiveness of a wide-scale community-based intervention in typically developing children. The sex differences reported may indicate the need to use different pedagogical and instructional strategies to enable boys and girls to develop and master a wide range of motor skills.

Adolescent Susceptibility to Peer Influence in Sexual Situations.

2016-03-01

One consistent predictor of adolescents' engagement in sexual risk behavior is their belief that peers are engaging in similar behavior; however, not all youth are equally susceptible to these peer influence effects. Understanding individual differences in susceptibility to peer influence is critical to identifying adolescents at risk for negative health outcomes. The purpose of this project was to identify predictors of susceptibility to peer influence using a novel performance-based measure of sexual risk taking. Participants were 300 early adolescents (Mage = 12.6 years; 53% female; 44% Caucasian) who completed (1) a pretest assessment of demographics, sexual attitudes, and hypothetical scenarios measuring the likelihood of engaging in sexual risk behavior and (2) a subsequent experimental procedure that simulated an Internet chat room in which youth believed that they were communicating with peers regarding these same hypothetical scenarios. In reality, these "peers" were computer-programmed e-confederates. Changes in responses to the sexual scenarios in the private pretest versus during the public chat room provided a performance-based measure of peer influence susceptibility. In total, 78% of youth provided more risky responses in the chat room than those in pretest. The most robust predictor of this change was gender, with boys significantly more susceptible to peer influence than girls. Significant interactions also were noted, with greater susceptibility among boys with later pubertal development and African-American boys. Results confirm that not all youth are equally susceptible to peer influence. Consistent with sexual script theory, boys evidence greater susceptibility to social pressure regarding sexual behavior than girls. Copyright © 2016 Society for Adolescent Health and Medicine.

A subset of obese individuals lacks cardiometabolic impairment. We aimed to analyze hormonal profiles of insulin-sensitive obese (ISO) and insulin-resistant obese (IRO) adolescents and determine hormonal predictors of homeostasis model of insulin resistance (HOMA-IR). A threshold of 3.16 of HOMA-IR was used to classify ISO (<3.16) IRO (≥3.16). In 702 individuals aged 13-18years (55.8% girls) anthropometric and laboratory [blood glucose, insulin, thyrotropin (TSH), free thyroxine (fT4), free triiodothyronine (fT3), sex hormone-binding globulin (SHBG), steroid hormones, luteinizing hormone, follicle stimulating hormone, prolactin, ghrelin, glucose-dependent insulinotropic polypeptide, glucagon-like-peptide 1glucagon, leptin, resistin, visfatin, leptin, adiponectin and adipsin] assessments were performed. Orthogonal projections to latent structures and Mann-Whitney tests with Bonferroni correction were applied for statistical analysis. 52.6% girls and 42.9% boys were insulin sensitive. In the predictive model of HOMA-IR thyroid function tests, adiponectin, ghrelin and leptin concentrations played an important role in both genders. Prolactin, testosterone and glucagon contributed to the model only in boys, while progesterone and dehydroepiandrosterone sulfate levels only in girls. After Bonferroni correction levels of leptin, adiponectin, leptin/adiponectin ratio, SHBG and fT4/TSH ratio in both genders, testosterone and glucagon levels in boys and levels of TSH and fT3 in girls were related to insulin sensitivity. Metabolic health defined by HOMA-IR is partly predicted by various hormones. Some of them are gender specific. Free T4/TSH and leptin/adiponectin ratios are related to insulin sensitivity in both genders. Copyright © 2016 Elsevier Inc. All rights reserved.

Adolescence is characterized by an increase in autonomy and the transformation of family relationships. Their experience has different meanings in future quality of life. To analyze the relationship between the sociodemographic variables, of Sexual context and attitudes adopted by teenagers facing sexuality with the organizational culture of the family. Observational descriptive and correlational, transversal study. The non-probabilistic convenience sample consists of 1216 adolescents attending the 9th year of study in Portuguese Public Schools and is part of the project PTDC/CPE-CED/103313/2008, the questionnaire applied was family organizational culture of Nave (2007) and attitudes towards sexuality of Nelas et al (2010). The majority lives in a village (47.5% of boys and 50.0% girls) .12.9%of boys do not use condoms in all relationships, and the same applies to 17.8% of girls. They belong mostly (55.8% boys and 49.5% girls) to a family with poor interpersonal relationships culture. The majority (51.8%) males and (58.9%) females have a family with moderate heuristic culture. Boys and girls (33.6% and 36.9%) both demonstrate a predominantly moderate hierarchy family culture and a moderate social goals family culture as well. Adolescents who have a bad attitude towards sexuality, mostly (43.2%) present a weak interpersonal relationships family culture with statistical significance (χ(2)=32,092, p=0.000) and have moderate hierarchy family culture and also moderate social goals family culture, without statistical significance. The family that loves, welcomes and cares is the same that educates and informs about sexuality, promoting youth empowerment making them safer, healthier and happier.

To examine the longitudinal relationship between exposure and receptivity to tobacco advertisements and progression towards tobacco use among adolescents in India. A 2-year longitudinal group-randomised trial, Mobilizing Youth for Tobacco Related Initiatives (MYTRI), was undertaken from 2004 to 2006 in 32 schools in Delhi and Chennai. Among the control schools (n=16), mixed-effects regression models were used to assess the objectives. Subjects Students who were non-susceptible, never users of tobacco (n=2782) at baseline (2004) in the control schools of Project MYTRI, who progressed academically and were followed up at endline (2006). Progression towards tobacco use (on tobacco uptake continuum). Bivariate results suggest that exposure to tobacco advertisements at baseline was associated in a dose-dependent manner with progression at endline. Students exposed at more than four places were 1.5 times (95% CI 1.12 to 1.94; p<0.05) more likely to progress towards tobacco use at endline versus those not exposed. Among boys, those exposed at more than four places were 1.7 times more likely to progress (95% CI 1.14 to 2.62; p<0.05). These significant results disappeared in multivariate analysis, when other psychosocial risk factors for tobacco use were controlled. In both bivariate and multivariate analyses, the risk of progression at endline was more than two times higher (95% CI 1.28 to 4.32; p<0.05) among boys who were highly receptive versus non-receptive boys. The same relationship did not hold among girls. High receptivity to tobacco advertising predicts future progression to tobacco use among boys in India. Suggestive evidence exists of a causal relationship between tobacco marketing and adolescent tobacco use.

Poor, powerless and pregnant. Empowering women will benefit all.

1992-07-01

In South Africa, the better educated women have a responsibility to help out less fortunate women. The possibilities for action could include the following: literacy classes for adult women with the help of teachers, librarians, social workers, development program workers, and among church groups and adult literacy groups; and promotion campaigns to encourage mothers to keep their children in school as long as possible. Women and teenagers could be educated about the complications of teenage births and parental responsibilities. Child spacing should be encouraged as a means of achieving better health and a higher standard of living. Women must be motivated to attend family planning clinics and health education programs. Income generation programs for women could be established. Community improvement projects and new housing projects could be instrumental in improving living conditions. Leadership courses and job creation for women must be provided. These activities would highlight women as assets, such as the UN Population Fund described in its 1992 report of The State of the World. Women's high status has been found to be directly related to economic growth and higher quality of life. 7-9% of a child's mortality risk might be reduced for each year of maternal education. In Africa, the ratio of girls to boys in school attendance averages 80 girls to 100 boys in primary school and 47 girls to 100 boys in secondary school. Almost 66% of adult illiterates were women in 1985: 949 million. Early marriage and childbearing perpetuates the cycle of low status and high fertility. Where human resource development has been high, such as in Asian countries, there have been as many as 78% of women active in the labor force. In South Africa, rural women have had as many as 7 children. The growth rate was 2.3% and population has been doubling every 32 years. At the present rate, greater numbers of women will be poor and illiterate, and their children will continue the cycle.

Evaluating Middle School Students' Spatial-scientific Performance in Earth-space Science

Many astronomical concepts cannot be understood without a developed understanding of four spatial-mathematics domains defined as follows: a) Geometric Spatial Visualization (GSV) - Visualizing the geometric features of a system as it appears above, below, and within the system’s plane; b) Spatial Projection (SP) - Projecting to a different location and visualizing from that global perspective; c) Cardinal Directions (CD) - Distinguishing directions (N, S, E, W) in order to document an object’s vector position in space; and d) Periodic Patterns - (PP) Recognizing occurrences at regular intervals of time and/or space. For this study, differences were examined between groups of sixth grade students’ spatial-scientific development pre/post implementation of an Earth/Space unit. Treatment teachers employed a NASA-based curriculum (Realistic Explorations in Astronomical Learning), while control teachers implemented their regular Earth/Space units. A 2-level hierarchical linear model was used to evaluate student performance on the Lunar Phases Concept Inventory (LPCI) and four spatial-mathematics domains, while controlling for two variables (gender and ethnicity) at the student level and one variable (teaching experience) at the teacher level. Overall LPCI results show pre-test scores predicted post-test scores, boys performed better than girls, and Whites performed better than non-Whites. We also compared experimental and control groups’ by spatial-mathematics domain outcomes. For GSV, it was found that boys, in general, tended to have higher GSV post-scores. For domains CD and SP, no statistically significant differences were observed. PP results show Whites performed better than non-Whites. Also for PP, a significant cross-level interaction term (gender-treatment) was observed, which means differences in control and experimental groups are dependent on students’ gender. These findings can be interpreted as: (a) the experimental girls scored higher than the control girls and/or (b) the control group displayed a gender gap in favor of boys while no gender gap was displayed within the experimental group.

To describe certain aspects of the physical and mental health of adolescents with restricted or deprived liberty as ordered by the court within the Youth Judicial Protection Service (YJP), and their ability to project themselves into the future. Survey by on-line self-administered questionnaires. Among the adolescents, 373 were randomly selected with restricted or deprived liberty, in the Lorraine region (eastern France). The data were managed and analyzed using the Modalisa(®) 7.0 (Kynos, Paris, France) survey processing software. Depending on the type of variable, comparisons were made using the chi-square test or analysis of variance. The significance threshold used was P<0.05. The response rate was 47%. The respondents included 820% boys and 18% girls, with a mean age of 16.4±1.5 years. More than nine out of ten stated that they were satisfied with their health. Among the girls, 16.7% stated that they had already had thoughts of suicide (boys, 3.8%; P<0.05). Of the total population, 24% said that during the last 12 months, they had needed to see a doctor (or healthcare professional), but they had had to give up the consultation at least once (too far, too expensive, etc.). Their average overall Rosenberg self-esteem score was 32.4±6.4, roughly the same as their peers in the general population (girls, 28.2; boys, 33.2; P<0.05). They said that they had projects for the future and nearly eight out of ten stated that they were confident in their own ability to succeed in their life, especially those who felt supported by their parents. To our knowledge, these facts had never been explored among adolescents with restricted or deprived liberty. This study shows results that do not match the usual representation of these adolescents by healthcare or education professionals. The quality of the work during the educational support given by the YJP Service could help explain these results. These findings need to be explored further by additional studies, which could also aim to measure the impact on physical and mental health of the educational support given by Youth Judicial Protection Service.

A sample of 472 preschoolers (4.43 ± 0.55 years; 55.1% boys) from 27 kindergartens (15 intervention, 12 control kindergartens) in Flanders, Belgium were included in the data analyses. Preschoolers wore an ActiGraph accelerometer for six consecutive days and were included in the data analyses if they had a minimum of two weekdays and one weekend day, both at baseline and follow-up (one year later). Preschoolers' PA outcomes were estimated for an average day, weekday, weekend day, during school hours, and during after school hours. To assess intervention effects, multilevel repeated measures analyses were conducted for the total sample, and for sub-groups (according to sex, kindergarten levels of socio-economic status (SES) and risk groups (low levels of PA at baseline)) of preschoolers. Small intervention effects were found in the total sample. Most intervention effects were found in boys and in preschoolers from high SES kindergartens. Boys from the intervention group had an increase in vigorous PA (ß=1.47, p=0.03) and moderate-to-vigorous PA (ß=1.27, p=0.03) from baseline to follow-up, whereas PA levels in boys from the control group stagnated or decreased. In preschoolers from high SES kindergartens, the largest effects were found for PA outcomes during school hours and during after school hours. The results from the Belgian sample demonstrate that effects of the PA-component of the ToyBox-intervention on objectively measured PA were found in preschool boys and in preschoolers from high SES kindergartens, which means that the ToyBox-intervention was mainly effective in those sub-groups. Future interventions should search for alternative strategies to increase preschoolers' PA levels in preschool girls and preschoolers from low SES kindergartens, as these are the most important at-risk groups regarding PA.

Association between physical activity and academic performance in Korean adolescent students

PubMed Central

2012-01-01

Background Recently, physical activity (PA) was found to improve cognitive and memory functions in the brain; however, no epidemiological studies have specifically investigated this phenomenon in the Korean adolescent student population. The purpose of this study was to investigate the effects of various types of PA undertaken at various frequencies, on the academic performance of Korean adolescent students. Methods A total of 75,066 adolescent students (39,612 males and 35,454 females) from the 7th to the 12th grades took part in the 5th Korea Youth Risk Behavior Web-based Survey (KYRBWS-V) project, conducted in 2009. Using data acquired by that survey, potential relations between PA and academic performance were explored in this current study through multivariate logistic regression analysis incorporating adjustment for covariate variables including age, body mass index, the parents’ education level, and the income status of the family. Results Compared with boys who did not regularly participate in any vigorous PA, those who did so 2, 3, or 4 times a week had greater odds of reporting an average or above-average academic performance. Compared with boys who did not participate in any moderate PA, those who did so 1, 2, 3, 4, or ≥5 times a week also had greater odds of reporting an average or above-average academic performance. Interestingly, when compared with boys who did not participate in any strengthening exercises, those undertaking strengthening exercises ≥5 times a week had lesser odds of reporting a below-average academic performance. Compared with girls who did not regularly participate in any vigorous PA, those who did so ≥5 times a week had greater odds of reporting an average or above-average academic performance. Compared with girls who did not participate in any moderate PA, those that did so 2 or 3 times a week had greater odds of reporting an average or above-average academic performance. Interestingly, when compared with girls who did not regularly participate in any strengthening exercises, those undertaking strengthening exercises ≥5 times a week had lesser odds of reporting a below-average academic performance. Conclusions Our analyses of the relevant data from the KYRBWS-V suggested that vigorous PA was positively correlated with academic performance in the case of boys, and moderate PA was positively correlated with academic performance in both boys and girls. However, strengthening exercises were not positively correlated with academic performance in boys or girls. Furthermore, when undertaken 5 or more times a week, vigorous PA in boys and strengthening exercises in both boys and girls were negatively correlated with academic performance. The results from this study are potentially relevant to the development of future education policies in Korean schools, particularly with regard to early intervention strategies designed to identify and counteract potential factors contributing to academic underachievement.

2005-01-01

In this stratified cross-sectional study in eight 'wet' and seven 'dry' schools, 1024 adolescent school children reported potentially building-related symptoms (BRS) in self-administrated questionnaires. From their classrooms dust samples were collected from floors, ventilation ducts, and air; settled dust was collected in cardboard boxes over a period of 5 months. Measurements of temperature, relative humidity and CO2 were performed. BRS were strongly associated with personal factors like recent airway infections, hay fever, asthma and psycho-social work load, but also to molds in floor dust and presence of mechanical ventilation. The association between molds in floor dust and BRS has in stratified analyses shown a strong association among adolescent school boys, and no association among adolescent school girls using multivariable analyses controlling for relevant confounders. In contrast to the menstruating school girls, the symptoms among the small group of not yet menstruating girls were associated with the levels of molds in floor dust. Their symptom prevalences were very similar to those of the boys. This finding makes us suggest a new hypothesis: The higher endogenous estrogen levels of sexually matured adolescent females seems to protect them from the effects of molds in dust, despite their overall higher symptom prevalence. In this cross-sectional epidemiological study of adolescent school children we found independent significant positive associations between building-related symptoms and viable molds in floor dust in boys and non-menstruating girls. In contrast, no such associations were seen among menstruating girls. The identification of these two susceptible groups adds further support the relevance of minimizing sources of dust and mold exposure.

Relationships among skeletal age (SA), body size and fundamental motor skills (FMS) and motor performance were considered in 155 boys and 159 girls 3-6 years of age. Stature and body mass were measured. SA of the hand-wrist was assessed with the Tanner-Whitehouse II 20 bone method. The Test of Gross Motor Development, 2 nd edition (TGMD-2) and the Preschool Test Battery were used, respectively, to assess FMS and motor performance. Based on hierarchical regression analyses, the standardized residuals of SA on chronological age (SAsr) explained a maximum of 6.1% of the variance in FMS and motor performance in boys (ΔR 2 3 , range 0.0% to 6.1%) and a maximum of 20.4% of the variance in girls (ΔR 2 3 , range 0.0% to 20.4%) over that explained by body size and interactions of SAsr with body size (step 3). The interactions of the SAsr and stature and body mass (step 2) explained a maximum of 28.3% of the variance in boys (ΔR 2 2 , range 0.5% to 28.3%) and 16.7% of the variance in girls (ΔR 2 2 , range 0.7% to 16.7%) over that explained by body size alone. With the exception of balance, relationships among SAsr and FMS or motor performance differed between boys and girls. Overall, SA per se or interacting with body size had a relatively small influence in FMS and motor performance in children 3-6 years of age. This article is protected by copyright.

Appropriate diet and physical activity are vital determinants of psychophysical development in children and adolescents. The aim of the study was to analyse an association between dietary habits and physical activity levels of adolescents from post-grammar schools. The study included 110 girls and 65 boys between 16 and 19 years of age from two post-grammar schools in Biała Podlaska in Poland. They were subjected to a diagnostic survey providing information on their diet (number of meals a day, their regularity, frequency of bread, dairy, meat, fish, sweet, fruit, vegetable and fast food consumption, preferred ways of food processing). Physical activity levels were determined with the International Physical Activity Questionnaire--Short Form (IPAQ-SF). Based on these data, the respondents were stratified to high, moderate and low physical activity groups. Due to small number of participants presenting with low physical activity levels, we did not include this group in further analyses. The significance of differences in the dietary habits of adolescents presenting with high and moderate physical activity levels was verified with the χ2 test. Most girls and boys presented with high levels of physical activity. However, we did not find an evident relationship between dietary habits and physical activity levels. Girls from high and moderate physical activity groups differed solely in terms of the number of daily meals, frequency of meat and sweet consumption, and significant intergroup differences observed among boys pertained to the frequencies of whole-wheat bread, meat and fast food consumption. The abovementioned food products were consumed more often by girls and boys presenting with high physical activity levels. The dietary mistakes observed in physically active adolescents from post-secondary schools justify intensification of their dietary education programs.

Adaptive behaviour is closely related to quality of life in children with intellectual disability (ID), but little is known about the adaptive behaviour of children with fragile X syndrome (FXS) in China. In boys with FXS, the adaptive behaviours in six domains, including self-dependence, locomotion, work skills, communication, socialisation and self-management, were assessed by the Infants-Junior Middle School Students Social-life Abilities Scale. In addition, we compared the adaptive skills of boys with FXS to those of three control groups of boys, including boys with Down syndrome (DS) and typically developing (TD) boys matched by chronological age (CA) or mental age (MA). The profile of the adaptive behaviour of boys with FXS is discussed in detail. Compared to boys with DS, boys with FXS obtained lower scores in three domains in adaptive behaviour, including work skills, socialisation and self-management skills; boys with FXS had better scores in self-dependence and locomotion skills than boys matched for MA; as expected, boys with FXS had significantly poorer adaptive skills in all six domains assessed compared to CA boys. The development of adaptive skills in boys with FXS was worse than that of boys with DS. The profile of the adaptive behaviour of boys with FXS establishes a basis for the development of targeted interventions to promote social development in this population. © 2015 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

To determine the prevalence of overweight in a sample of urban American Indian adolescents and identify associated behavioral, personal, and socioenvironmental factors. Participants were 246 American Indian boys and girls from the Saint Paul-Minneapolis metropolitan area of Minnesota who completed classroom surveys and anthropometric measurements as part of Project EAT (Eating Among Teens), a population-based study of adolescent nutrition and weight. Survey items assessed behavioral factors (physical activity, television/video viewing, snacking and meal patterns, weight control behaviors), personal factors (body satisfaction, nutrition knowledge, nutrition/fitness attitudes, self-efficacy to make healthy food choices, perceived benefits/barriers to healthy eating), and socioenvironmental factors (family meal routines, family connectedness, parental attitudes regarding nutrition/fitness, availability of household foods, peer attitudes about weight and fitness). Overweight prevalence (body mass index > or =85th percentile) was 43% and 39% for American Indian boys and girls. Compared to nonoverweight American Indian youth, overweight American Indian youth reported watching more hours of television/videos, greater use of weight control behaviors, less frequent snacking, caring less about fitness, lower body satisfaction, and greater parental concern about weight. Obesity prevention programs targeting American Indian adolescents should focus on reducing time spent watching television/videos, screening for unhealthy weight-control behaviors, improving body satisfaction, and providing support for families to integrate healthy eating into their busy lifestyles.

The incidence of type 1 diabetes mellitus (T1DM) is increasing rapidly worldwide for children of every age group. A retrospective analysis of hospital registration data from five tertiary hospitals in Beijing, China, identified 485 patients (210 boys, 275 girls) younger than 15 years of age with newly diagnosed T1DM between 1995 and 2010. From 1995 to 2010, the incidence of T1DM in patients <15 years of age ranged from 0.935-3.26 per 100,000 per year. During this period, the average age-standardized incidence rate was 1.7 per 100,000 per year, and the average annual increase in T1DM incidence was 4.36%. The highest rate increases occurred in boys and in patients <5 years of age. For both genders and all age groups, T1DM incidence increased at an accelerated rate after 2006. By 2020, the incidence of T1DM among children in Beijing is projected to increase by a factor of 1.69. The incidence of T1DM among patients younger than 15 years of age in Beijing increased from 1995 to 2010, with rates growing at an accelerated pace since 2006. Based on recent trends, we project continued rapid growth in the number of new childhood T1DM cases in Beijing.

Adolescent pregnancy places girls at increased risk for poor health and educational outcomes that limit livelihood options, economic independence, and empowerment in adulthood. In Tanzania, adolescent pregnancy remains a significant concern, with over half of all first births occurring before women reach the age of 20. A participatory research and action project (Vitu Newala) conducted formative research in a rural district on the dynamics of sexual risk and agency among 82 girls aged 12-17. Four major risk factors undermined girls' ability to protect their own health and well-being: poverty that pushed them into having sex to meet basic needs, sexual expectations on the part of older men and boys their age, rape and coercive sex (including sexual abuse from an early age), and unintended pregnancy. Transactional sex with older men was one of the few available sources of income that allowed adolescent girls to meet their basic needs, making this a common choice for many girls, even though it increased the risk of unintended (early) pregnancy. Yet parents and adult community members blamed the girls alone for putting themselves at risk. These findings were used to inform a pilot project aimed to engage and empower adolescent girls and boys as agents of change to influence powerful gender norms that perpetuate girls' risk.

This investigation aims to evaluate the validity of self-assessment of pubertal Tanner stage in representative Chinese children and adolescents. The study is a nationally representative cross-sectional survey in eight research sites in the large project entitled 'China Puberty Research Collaboration'. Weight, height, self-assessed pubertal Tanner stage and physical examination of pubic hair in each gender, breast development in girls and genital development in boys from were analysed. Realistic colour images of pubertal rating were used as self-assessment of pubertal stage. A large proportion of subjects aged 7.9-18.9 years old were capable of identifying their own pubertal Tanner stage accurately or close to the rater's assessments. Obese group tends to overestimate their pubertal development compared to non-obese peers, except for genital assessment in boys. The k values for non-obese and obese girls were 0.619 (p < 0.0001) and 0.527 (p < 0.0001), respectively, while the k values for non-obese and obese boys were 0.503 (p < 0.0001) and 0.352 (p < 0.0001). Self-assessment of the pubertal stage by using realistic colour images could be a better alternative assessment tool for large epidemiological puberty research compared with Tanner's original black and white pictures. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

2007-08-01

The present study was designed to determine the weight-based stigmatization of Mexican overweight (OW) and non-OW children by their mothers and peers, who rated both boys and girls with varying physical characteristics. Four hundred and thirty-two fifth and sixth graders and 342 mothers participated in the study. Children were administered a questionnaire displaying six drawings. Participants' responses were numbered in order of preference from 1 to 6 (most to least well liked). Participants were divided into categories based on socioeconomic status, ethnicity, and current body mass index. The majority of children chose the child in a wheelchair as the preferred friend. Boys and girls, Indian and non-Indian, with and without risk of OW chose the obese peer as the least-preferred friend. Non-OW girls and their mothers liked the obese child less than non-OW boys and their mothers. Agreement correlations between mothers and children were rho = 0.19 (P = 0.0001), rho = 0.17 (P = 0.001), and rho = 0.13 (P = 0.02) for the healthy child, child with missing arm, and obese child, respectively. There was a strong correlation between Indian mothers and non-OW daughters (rho = 0.54, P = 0.009) on choosing the drawing of the obese child as the least preferred friend. These data suggest an influential effect of the negative attitude of mothers toward the obese child, which are projected to their children.

To compare the long-term effectiveness and cost-effectiveness of 3 approaches to managing elevated blood pressure (BP) in adolescents in the United States: no intervention, "screen-and-treat," and population-wide strategies to lower the entire BP distribution. We used a simulation model to combine several data sources to project the lifetime costs and cardiovascular outcomes for a cohort of 15-year-old U.S. adolescents under different BP approaches and conducted cost-effectiveness analysis. We obtained BP distributions from the National Health and Nutrition Examination Survey 1999-2004 and used childhood-to-adult longitudinal correlation analyses to simulate the tracking of BP. We then used the coronary heart disease policy model to estimate lifetime coronary heart disease events, costs, and quality-adjusted life years (QALY). Among screen-and-treat strategies, finding and treating the adolescents at highest risk (eg, left ventricular hypertrophy) was most cost-effective ($18000/QALY [boys] and $47000/QALY [girls]). However, all screen-and-treat strategies were dominated by population-wide strategies such as salt reduction (cost-saving [boys] and $650/QALY [girls]) and increasing physical education ($11000/QALY [boys] and $35000/QALY [girls]). Routine adolescents BP screening is moderately effective, but population-based BP interventions with broader reach could potentially be less costly and more effective for early cardiovascular disease prevention and should be implemented in parallel.

2008-12-01

The objective of this study was to determine the prevalence of overweight and obesity among Brazilian schoolchildren according to gender, age and geographic region. A descriptive association study was conducted on 36,976 schoolchildren (20,914 boys and 16,062 girls aged 10 to 15 years) between 2004 and 2005 using secondary data originating from a school-based cross-sectional epidemiological survey. The cut-off body mass index proposed by the International Obesity Task Force was used as diagnostic criterion for overweight and obesity. The prevalence of overweight and obesity was 11.9% and 2.6%, respectively, with a higher proportion of overweight among girls and of obesity among boys. An association was observed between overweight, age and region, with the demonstration of higher odds ratios for overweight among children aged 10 to 13 years and children from the South, Center-West and Southeast regions. Obesity was significantly associated with gender, age and region, indicating higher odds ratios among boys, children aged 10 to 13 years and children from the South and Southeast regions. Although lower than that observed in most developed countries, the prevalence of overweight and obesity among Brazilian schoolchildren is a matter of concern. In this respect, health policies and strategies should take into account gender and age of the individuals and geographic region of the country.

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

In spite of protection against the targeted infections, a large volume of observational data indicates that diphtheria-tetanus-pertussis (DTP) vaccine may have a negative impact on overall childhood mortality in low-income countries, especially in girls. In an observational study using data from Bandim Health Project's continuous registration of all admissions to the paediatric ward at the National Hospital Simão Mendes in Bissau, we investigated whether DTP was associated with higher female than male in-hospital mortality (female/male case fatality ratio (F/M CFR)) and whether the CFR comparing DTP-vaccinated and DTP-unvaccinated children differed by sex. We included children aged 6 weeks to 8 months (274 days) admitted to the paediatric ward with a vaccination card seen during admission. From May 2001 to January 2008, 4230 children aged 6 weeks to 8 months were admitted and 3450 (82%; 1997 boys, 1453 girls) presented a vaccination card. The proportion presenting a vaccination card and DTP coverage did not differ by sex. During admission, 16% (200/1250) of the girls and 13% (220/1694) of the boys who had received DTP died. The F/M CFR among the 2944 DTP-vaccinated children was 1.23 (1.03-1.46); while it was 0.95 (0.66-1.38) among the 506 children who had not received DTP. DTP-vaccinated children were older and had better socioeconomic status. Adjusted for age, BCG-vaccination, residence, and maternal education the CFR comparing DTP-vaccinated boys with DTP-unvaccinated boys was 0.84 (0.63-1.11), while the CFR comparing DTP-vaccinated girls with DTP-unvaccinated girls was 1.28 (0.90-1.83) (p = .07 for same effect in boys and girls). Among DTP-vaccinated children, female in-hospital mortality was higher than male in-hospital mortality and DTP-vaccination tended to be associated with higher mortality in girls. The data are consistent with DTP having negative effects on mortality for girls. Further studies are necessary to design the optimal vaccination programme for both sexes.

Students' learning interests and attitudes toward science have both been studied for decades. However, the connection between them with students' life experiences about science and technology has not been addressed much. The purpose of this study is to investigate students' learning interests and life experiences about science and technology, and also their attitudes toward technology. A total of 942 urban ninth graders in Taiwan were invited to participate in this study. A Likert scale questionnaire, which was developed from an international project, ROSE, was adapted to collect students' ideas. The results indicated that boys showed higher learning interests in sustainability issues and scientific topics than girls. However, girls recalled more life experiences about science and technology in life than boys. The data also presented high values of Pearson correlation about learning interests and life experiences related to science and technology, and in the perspective on attitudes towards technology. Ways to promote girls' learning interests about science and technology and the implications of teaching and research are discussed as well.

Purpose To examine how the timing of hypoxic exposure results in specific childhood outcomes and whether there is a differential effect by sex. Methods A sample of 10,879 prospectively followed pregnancies was drawn from the Boston and Providence sites (New England-NE) of the National Collaborative Perinatal Project. Based on placental pathology, we developed and validated a measure of probable chronic fetal hypoxia (CHP) and contrasted the effects of acute perinatal hypoxia on age 7 emotional, behavioral, and cognitive outcomes. Results Perinatal hypoxia had a significant impact on multiple behavioral and cognitive outcomes in boys and girls by age 7, in contrast to probable CHP which had a differential effect on girls and boys such that there was decreased verbal IQ and increased inhibition in females alone. Conclusions Findings underscore the importance of considering the timing of obstetric complications and offspring sex in investigations of the impact of fetal and perinatal hypoxia on offspring’s outcomes throughout the life course.

Abu Dhabi high school students' interest in physics in different contexts was investigated with a survey conducted in connection with the international project, The Relevance of Science Education (ROSE). The sample consisted of 2248 students in public and private schools. Means of most items that belong to the school physics context for both girls and boys were below the score of (3.0). The most interesting topics for both genders were connected with fantasy items. The least interesting items (particularly for girls) were connected with artifacts and technological processes. Girls assigned the highest scores for "why we dream" and "life and death." Boys assigned the highest scores for "inventions and discoveries" and "life outside of earth." The main message of the study is that new curricular approaches and textbooks can be developed through combining technological and human contexts. The implications for curriculum development, teacher professional development programs, and other education strategies in Abu Dhabi are discussed in light of the ROSE survey.

The proportion of overweight adolescents has increased, but the behavioral risk factors for overweight youth are not well understood. To examine how diet, physical activity, and sedentary behaviors relate to overweight status in adolescents. Baseline data from the Patient-Centered Assessment and Counseling for Exercise Plus Nutrition Project, a randomized controlled trial of adolescents to determine the effects of a clinic-based intervention on physical activity and dietary behaviors. A total of 878 adolescents aged 11 to 15 years, 42% of whom were from minority backgrounds. Centers for Disease Control and Prevention body mass index-for-age percentiles divided into 2 categories: normal weight (<85th percentile) and at risk for overweight plus overweight (AR + O) (>or=85th percentile). Overall, 45.7% of the sample was classified as AR + O with a body mass index for age at the 85th percentile or higher. More girls from minority backgrounds (54.8%) were AR + O compared with non-Hispanic white girls (42%) (chi(2)(1) = 7.6; P =.006). Bivariate analyses indicated that girls and boys in the AR + O group did fewer minutes per day of vigorous physical activity, consumed fewer total kilojoules per day, and had fewer total grams of fiber per day than those in the normal-weight group. Boys in the AR + O group also did fewer minutes per day of moderate physical activity and watched more minutes per day of television on nonschool days than normal-weight boys. Final multivariate models indicated that independent of socioeconomic status (as assessed by household education level), girls had a greater risk of being AR + O if they were Hispanic or from another minority background (odds ratio [OR] = 1.65; 95% confidence interval [CI], 1.09-2.49) and a reduced risk of being AR + O as minutes per day of vigorous physical activity increased (OR = 0.93; 95% CI, 0.89-0.97). A low level of vigorous physical activity was the only significant risk factor for boys being AR + O (OR = 0.92; 95% CI, 0.89-0.95). Analyses based on meeting behavioral guidelines supported these findings and showed that failing to meet the 60 min/d moderate to vigorous physical activity guideline was associated with overweight status for both girls and boys. In addition, boys who failed to meet sedentary behavior and dietary fiber guidelines were more likely to be overweight. Of the 7 dietary and physical activity variables examined in this cross-sectional study, insufficient vigorous physical activity was the only risk factor for higher body mass index for adolescent boys and girls. Prospective studies are needed to clarify the relative importance of dietary and physical activity behaviors on overweight in adolescence.

2014-01-01

Background Fragile X syndrome (FXS) and Down syndrome (DS) are the two leading genetic causes of intellectual disability, and FXS is the most common known genetic condition associated with autism. Both FXS and DS are associated with significant language impairment, but little is known about expressive language across domains over time or the role of autism in language development in FXS. Aims To compare three domains of language production (vocabulary, syntax, and pragmatics) over time within and across groups of boys with FXS with and without autism spectrum disorder (FXS-ASD, FXS-O), boys with DS, and typically developing (TD) boys. Methods & Procedures Twenty-nine boys with FXS-O, 40 boys with FXS-ASD, 34 boys with DS, and 48 younger TD boys of similar nonverbal mental age living in the United States participated. The Antonyms, Syntax Construction, and Pragmatic Judgment subtests of the Comprehensive Assessment of Spoken Language were administered annually over three years. Outcomes & Results TD boys scored higher than all other groups on all three subtests, boys with FXS-O and FXS-ASD scored higher than boys with DS in Syntax Construction, and boys with FXS-O scored higher than boys with FXS-ASD in Pragmatic Judgment. Within-group patterns varied between groups. Overall the TD group showed significantly more change over time than all other groups. Conclusions & Implications Findings suggest that expressive language skills and growth across various domains are more impaired in boys with FXS and DS than would be expected based on nonverbal mental age, that for boys with DS syntax is more impaired than would be expected based on intellectual disability, and that autism status affects pragmatic language in boys with FXS. Findings suggest that language production across domains should be addressed during assessment and intervention for boys with FXS and boys with DS, with differing group profiles also suggesting potentially different areas of focus.

Bagwell, Catherine L; Coie, John D

2004-05-01

The current study examined the best friendships of aggressive and nonaggressive boys (N = 96 boys, 48 dyads, mean age = 10.6 years). Friends completed self-report measures of friendship quality, and their interactions were observed in situations that required conflict management and provided opportunities for rule-breaking behavior. Although there were no differences in boys' self-reports of friendship quality, observers rated nonaggressive boys and their friends as showing greater positive engagement, on-task behavior, and reciprocity in their interactions compared with aggressive boys and their friends. Aggressive boys and their friends provided more enticement for rule violations and engaged in more rule-breaking behavior than did nonaggressive boys and their friends. Also, the intensity of negative affect in observed conflicts between aggressive boys and their friends was greater than that between nonaggressive boys and their friends. The findings suggest that friendships may provide different developmental contexts for aggressive and nonaggressive boys. Copyright 2003 Elsevier, Inc.

NASA maintains excellence in its spaceflight systems by utilizing rigorous engineering processes based on over 50 years of experience. The NASA systems engineering process for flight projects described in NPR 7120.5E was initially developed for major flight projects. The design and development of low-cost small satellite systems does not entail the financial and risk consequences traditionally associated with spaceflight projects. Consequently, an approach is offered to tailoring of the processes such that the small satellite missions will benefit from the engineering rigor without overly burdensome overhead. In this paper we will outline the approaches to tailoring the standard processes for these small missions and describe how it will be applied in a proposed small satellite mission.

Framing black boys: parent, teacher, and student narratives of the academic lives of black boys.

PubMed

Rowley, Stephanie J; Ross, Latisha; Lozada, Fantasy T; Williams, Amber; Gale, Adrian; Kurtz-Costes, Beth

2014-01-01

The discourse on Black boys tends to suggest that Black boys are in complete peril. We begin with evidence that Black boys are excelling in certain contexts (i.e., in certain states, in certain schools, and in certain courses). We then discuss the ways in which the narratives used by parents, teachers, and Black boys themselves may serve to further reinforce views that Black boys are beyond hope. Research on Black parents suggests that they tend to view their sons as vulnerable and have lower expectations for sons than for daughters. Studies of teachers show that they tend to view Black boys as unteachable, as social problems, and as scary. Research on Black boys shows that they are sometimes complicit in supporting these narratives by engaging in negative or ste reotypical behavior. We also include recent research that includes counter-narratives of Black boys. We end with suggestions for future research.

Gender, culture, and sex-typed cognitive abilities.

PubMed

Reilly, David

2012-01-01

Although gender differences in cognitive abilities are frequently reported, the magnitude of these differences and whether they hold practical significance in the educational outcomes of boys and girls is highly debated. Furthermore, when gender gaps in reading, mathematics and science literacy are reported they are often attributed to innate, biological differences rather than social and cultural factors. Cross-cultural evidence may contribute to this debate, and this study reports national gender differences in reading, mathematics and science literacy from 65 nations participating in the 2009 round of the Programme for International Student Assessment (PISA). Consistently across all nations, girls outperform boys in reading literacy, d = -.44. Boys outperform girls in mathematics in the USA, d = .22 and across OECD nations, d = .13. For science literacy, while the USA showed the largest gender difference across all OECD nations, d = .14, gender differences across OECD nations were non-significant, and a small female advantage was found for non-OECD nations, d = -.09. Across all three domains, these differences were more pronounced at both tails of the distribution for low- and high-achievers. Considerable cross-cultural variability was also observed, and national gender differences were correlated with gender equity measures, economic prosperity, and Hofstede's cultural dimension of power distance. Educational and societal implications of such gender gaps are addressed, as well as the mechanisms by which gender differences in cognitive abilities are culturally mediated.

Concerns over anxiety and depressive symptoms in children with premature adrenarche (PA) have been recently raised. However, to date, most relevant studies are on a small number of girls. In this cross-sectional study, 82 pre-pubertal children (66 girls and 16 boys) diagnosed with PA, were compared to 63 control children regarding their psychological characteristics and hypothalamic-pituitary-adrenal (HPA) axis function, as assessed by salivary cortisol measurement. Symptoms of anxiety and depression were assessed by child self-report (Spence Children's Anxiety Scale (SCAS) and Depression self-rating scale for Children (DSRS)) and parent-report (Child Behaviour Checklist (CBCL)) tests validated for the Greek population. Salivary cortisol levels were determined directly after awakening (approximately 7am) and evening (8pm) of the same day. Morning serum DHEAS levels were assessed in PA children. Girls with PA scored significantly higher on anxiety (p = .016) and depression (p =.039) scales than controls. No group differences were noted for parent reports and children's salivary cortisol concentrations. Boys with PA did not demonstrate significant differences in any of the aforementioned parameters. Our findings suggest that girls with PA may be at higher risk for reporting symptoms of anxiety and depression than their non-PA peers. HPA axis dysregulation in this population was not documented.

Pubertal development and final height after autologous bone marrow transplantation for acute lymphoblastic leukemia.

We describe pubertal development and growth in 17 children who underwent bone marrow transplantation (BMT), including total body irradiation (TBI) for ALL. Seven children also received cranial irradiation (CI) and five boys testicular irradiation. All underwent transplantation before (n=15) or at the beginning of (n=2) puberty and reached a final height (FH). Puberty started spontaneously in all boys not given testicular irradiation. All boys who received testicular irradiation developed hypergonadotrophic hypogonadism. Puberty started spontaneously in two girls and was induced with increasing doses of ethinylestradiol in two girls. In two girls, a low dose of ethinylestradiol was given until menarche. In one girl with early onset of puberty and short stature, puberty was blocked with a GnRH analogue. The standard deviation score for height decreased significantly from BMT to FH, both in the children who received TBI only (-1.1, P=0.005) as well as in those given additional CI (-1.7, P=0.027). Most of the loss occurred during puberty. In all, 10 children received growth hormone (GH) treatment. CI, young age at BMT, and short duration of GH treatment were predictors of height loss after BMT. Although limited by the small and heterogeneous sample, our study supports the use of early GH treatment in children with decelerating growth rate and low GH levels.

Accurate calculations of testicular volume standard deviation (SD) scores are not currently available. We constructed LMS-smoothed age-reference charts for testicular volume in healthy boys. The LMS method was used to calculate reference data, based on testicular volumes from ultrasonography and Prader orchidometer of 769 healthy Dutch boys aged 6 months to 19 years. We also explored the association between testicular growth and pubic hair development, and data were compared to orchidometric testicular volumes from the 1997 Dutch nationwide growth study. The LMS-smoothed reference charts showed that no revision of the definition of normal onset of male puberty - from nine to 14 years of age - was warranted. In healthy boys, the pubic hair stage SD scores corresponded with testicular volume SD scores (r = 0.394). However, testes were relatively small for pubic hair stage in Klinefelter's syndrome and relatively large in immunoglobulin superfamily member 1 deficiency syndrome. The age-corrected SD scores for testicular volume will aid in the diagnosis and follow-up of abnormalities in the timing and progression of male puberty and in research evaluations. The SD scores can be compared with pubic hair SD scores to identify discrepancies between cell functions that result in relative microorchidism or macroorchidism. ©2015 Foundation Acta Paediatrica.

Late presentation of congenital adrenal hyperplasia as a 46,XX disorder of sex development due to 11-beta hydroxylase deficiency is uncommon. Such a case raises issues regarding appropriate investigation and management. A 5-year-old boy who had recently moved to the United Kingdom presented at the endocrinology clinic with recurrent abdominal pain. He was normotensive and had a history of ambiguous genitalia since birth, a relatively small penis, bilateral cryptorchidism and pubic hair. A systematic workup revealed low anti-Mullerian hormone levels for age and sex and elevated serum testosterone, androstenedione and deoxycortisol levels. A urinary steroid profile confirmed a diagnosis of 11-beta hydroxylase deficiency. The child's karyotype was 46,XX. Further genetic analysis revealed a compound heterozygote mutation in the CYP11B1 gene. Ultrasound scan showed evidence of Mullerian structures and accumulation of menstrual blood in the vagina (haematocolpos). Following discussion at a multidisciplinary clinic, the patient did not undergo sex reassignment and subsequently proceeded to surgery for removal of the Mullerian structures. This case emphasizes the importance of a systematic approach to investigation of older children presenting with apparent male undermasculinisation. It also raises important issues about gender reassignment in mid-childhood and the indications for removal of Mullerian organs in a 46,XX boy. Copyright 2009 S. Karger AG, Basel.

Response perseveration and sensitivity to reward and punishment in boys with oppositional defiant disorder.

Response perseveration is the tendency to continue a response set for reward despite punishment. In the present study, response perseveration and sensitivity to reward and punishment were assessed in boys with oppositional defiant disorder (ODD). The study also examined the relation between punishment sensitivity and autonomic arousal. Nineteen ODD boys (mean age 9.8 years) and 20 normal control boys (NC) (mean age 9.7 years) were administered the door-opening task. In this task, the subject chooses either to open the next door or to stop playing; the opening of doors is initially rewarded and then increasingly punished. ODD boys opened more doors than NC boys. Following punishment, ODD boys took less time than NC boys before opening the next door, but did not differ from NC boys in time after reward. Mean skin conductance level was lower in ODD boys than in NC boys. The correlation coefficient between time after punishment and skin conductance level was moderately positive in the total sample. These results suggest that response perseveration in ODD boys is related to low punishment sensitivity and that skin conductance level is a marker of punishment sensitivity.

Concussion-Like Symptoms in Child and Youth Athletes at Baseline: What Is “Typical”?

Hunt, Anne Williams; Paniccia, Melissa; Reed, Nick; Keightley, Michelle

2016-01-01

Context: After a concussion, guidelines emphasize that an athlete should be asymptomatic before starting a return-to-play protocol. However, many concussion symptoms are nonspecific and may be present in individuals without concussion. Limited evidence exists regarding the presence of “typical” or preinjury (baseline) symptoms in child and youth athletes. Objective: To describe the frequency of symptoms reported at baseline by child and youth athletes and identify how age, sex, history of concussion, and learning factors influence the presence of baseline symptoms. Design: Cross-sectional cohort study. Setting: Baseline testing was conducted at a hospital research laboratory or in a sport or school setting (eg, gym or arena). Patients or Other Participants: A total of 888 child (9−12 years old, n = 333) and youth (13−17 years old, n = 555) athletes participated (46.4% boys and 53.6% girls, average age = 13.09 ± 1.83 years). Main Outcome Measure(s): Demographic and symptom data were collected as part of a baseline protocol. Age-appropriate versions of the Post-Concussion Symptom Inventory (a self-report concussion-symptoms measure with strong psychometric properties for pediatric populations) were administered. Demographic data (age, sex, concussion history, learning factors) were also collected. Results: Common baseline symptoms for children were feeling sleepier than usual (30% boys, 24% girls) and feeling nervous or worried (17% boys, 25% girls). Fatigue was reported by more than half of the youth group (50% boys, 67% girls). Nervousness was reported by 32% of youth girls. Headaches, drowsiness, and difficulty concentrating were each reported by 25% of youth boys and girls. For youths, a higher total symptom score was associated with increasing age and number of previous concussions, although these effects were small (age rs = 0.143, number of concussions rs = .084). No significant relationships were found in the child group. Conclusions: Children and youths commonly experienced symptoms at baseline, including fatigue and nervousness. Whether clinicians should expect complete symptom resolution after concussion is not clear. PMID:27834505

Prenatal phthalate exposure and reduced masculine play in boys.

Foetal exposure to antiandrogens alters androgen-sensitive development in male rodents, resulting in less male-typical behaviour. Foetal phthalate exposure is also associated with male reproductive development in humans, but neurodevelopmental outcomes have seldom been examined in relation to phthalate exposure. To assess play behaviour in relation to phthalate metabolite concentration in prenatal urine samples, we recontacted participants in the Study for Future Families whose phthalate metabolites had been measured in mid-pregnancy urine samples. Mothers completed a questionnaire including the Pre-School Activities Inventory, a validated instrument used to assess sexually dimorphic play behaviour. We examined play behaviour scores (masculine, feminine and composite) in relationship to (log(10)) phthalate metabolite concentrations in mother's urine separately for boys (N = 74) and girls (N = 71). Covariates (child's age, mother's age and education and parental attitude towards atypical play choices) were controlled using multivariate regression models. Concentrations of dibutyl phthalate metabolites, mono-n-butyl phthalate (MnBP) and mono-isobutyl phthalate (MiBP) and their sum, were associated with a decreased (less masculine) composite score in boys (regression coefficients -4.53,-3.61 and -4.20, p = 0.01, 0.07 and 0.04 for MnBP, MiBP and their sum respectively). Concentrations of two urinary metabolites of di(2-ethylhexyl) phthalate (DEHP), mono-(2-ethyl-5-oxohexyl) phthalate (MEOHP) and mono-(2-ethyl-5-hydroxyhexyl) phthalate (MEHHP) and the sum of these DEHP metabolites plus mono(2-ethylhexyl) phthalate were associated with a decreased masculine score (regression coefficients -3.29,-2.94 and -3.18, p = 0.02, 0.04 and 0.04) for MEHHP, MEOHP and the sum respectively. No strong associations were seen between behaviour and urinary concentrations of any other phthalate metabolites in boys, or between girls' scores and any metabolites. These data, although based on a small sample, suggest that prenatal exposure to antiandrogenic phthalates may be associated with less male-typical play behaviour in boys. Our findings suggest that these ubiquitous environmental chemicals have the potential to alter androgen-responsive brain development in humans.

To investigate whether children with probable or definite differences in sensory processing (SP) had participation restrictions, and the relationship between Short Sensory Profile (SSP) scores and children's participation. The participants were parents of 64 children (mean age 8 years 1 month); 36 with potential impairments in regulating sensory input and filtering out unnecessary stimuli (29 boys, 7 girls) and 28 with typical SP abilities (25 boys, 3 girls). Parents' completed the SSP and Participation in Childhood Occupations Questionnaire (PICO-Q). The SSP score was used to categorize children as potential SP impairment group and typical SP ability group. Children categorized as having probable or definite differences in SP exhibited significantly lower participation levels and enjoyment than children categorized as having typical SP abilities. However, participation frequency between both groups was similar. Six out of the seven SP impairment types had small to moderate correlations with children's participation (r = 0.25-0.48, p < 0.05). Multiple regression analyses indicated that only three impairment types (Underresponsive/Seeks Sensation, Low Energy/Weak, and Visual/Auditory Sensitivity) were significant predictors of PICO-Q participation domains. The results suggest that children with potential SP impairments have restrictions in the degree of participation and enjoyment. Three SP types were related to specific participation domains, but they explained a small amount of variance or none in some participation domains. Other variables should be considered to identify determinants of children's participation.

Feedback processing in adolescence: an event-related potential study of age and gender differences.

2014-01-01

Adolescence has frequently been characterized as a period of increased risk taking, which may be largely driven by maturational changes in neural areas that process incentives. To investigate age- and gender-related differences in reward processing, we recorded event-related potentials (ERPs) from 80 participants in a gambling game, in which monetary wins and losses were either large or small. We measured two ERP components: the feedback-related negativity (FRN) and the feedback P3 (fP3). The FRN was sensitive to the size of a win in both adult (aged 23-35 years) and adolescent (aged 13-17 years) males, but not in females. Small wins appeared to be less rewarding for males than for females, which may in part explain more approach-driven behavior in males in general. Furthermore, adolescent boys showed both delayed FRNs to high losses and less differentiation in FRN amplitude between wins and losses in comparison to girls. The fP3, which is thought to index the salience of the feedback at a more conscious level than the FRN, was also larger in boys than in girls. Taken together, these results imply that higher levels of risk taking that are commonly reported in adolescent males may be driven both by hypersensitivity to high rewards and insensitivity to punishment or losses. © 2014 S.

Are the performance overestimates given by boys with ADHD self-protective?

PubMed

Ohan, Jeneva L; Johnston, Charlotte

2002-06-01

Tested the self-protective hypothesis that boys with attention deficit hyperactivity disorder (ADHD) overestimate their performance to protect a positive self-image. We examined the impact of performance feedback on the social and academic performance self-perceptions of 45 boys with and 43 boys without ADHD ages 7 to 12. Consistent with the self-protective hypothesis, positive feedback led to increases in social performance estimates in boys without ADHD but to decreases in estimates given by boys with ADHD. This suggests that boys with ADHD can give more realistic self-appraisals when their self-image has been bolstered. In addition, social performance estimates in boys with ADHD were correlated with measures of self-esteem and positive presentation bias. In contrast, for academic performance estimates, boys in both groups increased their performance estimates after receiving positive versus average or no feedback, and estimates were not correlated with self-esteem or social desirability for boys with ADHD. We conclude that the self-protective hypothesis can account for social performance overestimations given by boys with ADHD but that other factors may better account for their academic performance overestimates.

Pratt, Jeremy John; Connell, Tom G; Bekhit, Elhamy; Crawford, Nigel W

2018-05-04

Splenic complications of invasive meningococcal disease (IMD) are well recognised, though cyst formation is rare, particularly in paediatric populations. The best approach to their management is not yet established. This case outlines the management of a splenic cyst in a 21-month-old boy following severe IMD. The case took place in the context of an acute emergence of serogroup W prompting significant media attention and subsequent change in vaccination practice at a jurisdictional level in Australia. The patient was critically unwell early in the illness, then later a collection in the left upper quadrant was detected, shown on ultrasound to be a 11.6×7.7 cm splenic cyst. In this case, the cyst was managed by ultrasound-guided drainage tube insertion. The residual collection was small and stable on subsequent imaging. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018. All rights reserved.

Boys or girls? Parents' preferences and sex control.

PubMed

Williamson, N E

1978-01-01

Recent evidence from the U.S. and from other selected countries is examined on parent sex preferences for their children and how strongly these are held. This involves the significance of these preferences, the social and economic conditions that foster different types of preferences, and how different individuals and societies deal with them. The traditional preference for boys appears to remain nearly universal, which runs contrary to the ideal of "every child a wanted child," and also presents an obstacle to desired declines in fertility in developing countries where sons are still perceived as needed for economic and emotional security. This tendency has been turned around in Japan, Singapore, Hong Kong, and the U.S., where small families are now the ideal. 3 basic approaches to the scientific selection of sex-specific sperm for preselection, the timing of sexual intercourse, the separation of male- and female-bearing sperm followed by artificial insemination, and selective abortion after fetal sex determination indicate that an effective and practical method of sex control is still further off than predicted.

A Human Case of Zoonotic Dog Tapeworm, Dipylidium caninum (Eucestoda: Dilepidiidae), in China

2017-01-01

We described a human case of zoonotic dog tapeworm, Dipylidium caninum (Eucestoda: Dilepidiidae), rarely occurring in China. The mother of a 17 month-old boy noted the appearance of small white and active worms over a month period in her son’s feces, but the boy was asymptomatic except mild diarrhea. We observed 3 tapeworm proglottids resembling cucumber seeds in his stool sample. Microscopically, each proglottid had 2 genital pores, 1 on each lateral edge, and numerous egg capsules in the uterus. The patient was successfully treated with a single oral dose of praziquantel. Adult worms were recovered in the diarrheic stool after praziquantel treatment and purgation. His family had household pet dogs for several years, and he might have acquired the infection by ingestion of infected fleas of his pet dogs. A history of dog or cat pets and flea bites may be important clues to diagnosis of D. caninum infection. The infected pets should also be treated. PMID:28285500

Subendocardial viability ratio (SEVR) is a reliable index of myocardial supply-workload balance. This study sought to investigate whether overweight/obese children and adolescents have altered SEVR and to identify which are the associated factors. This cross-sectional study involved 789 individuals. Central haemodynamic was measured by radial applanation tonometry. Diastolic time was shorter (496 ± 122 vs 537 ± 140 ms, P = .014) and diastolic pressure-time index was lower (2681 ± 412 vs 2814 ± 423 mm Hg seconds, P = .024) in overweight/obese compared with eutrophic girls. SEVR was lower in girls than in boys (1.34 ± 0.39 vs 1.48 ± 0.41, P = .018) but only among overweight/obese. SEVR may be affected by small variations in the temporal determinants of cardiac cycle. © 2018 John Wiley & Sons Australia, Ltd.

Although the Chinese government provides free-of-charge voluntary HIV counseling and testing, HIV testing rates among men who have sex with men (MSM) are reported to be extremely low. This study examines the association of structural and psychosocial factors and social network characteristics with HIV testing behaviors among "money boys" and general MSM in Shanghai. Overall, 28.5% of "money boys" and 50.5% of general MSM had never tested for HIV despite high rates of reported HIV risk behaviors. Factors associated with not testing for HIV included: not knowing of a testing site, limited HIV knowledge, low perceived HIV risk, concern about HIV testing confidentiality, being a closeted gay, not using the Internet, and having a small social network or network with few members who had tested for HIV. Future efforts to promote HIV testing should focus on outreach to general MSM, confidentiality protection, decreasing the stigma of homosexuality, and encouraging peer education and support through the Internet and social networks.

Prader-Willi syndrome: genetic tests and clinical findings.

2000-01-01

Here we describe the genetic studies performed in 53 patients with the suspected diagnosis of Prader-Willi syndrome (PWS). PWS is characterized by neonatal hypotonia, hypogonadism, delayed psychomotor development, hyperphagia, obesity, short stature, small hands and feet, learning disabilities, and obsessive-compulsive behavior. Through the methylation analysis of the SNRPN gene, microsatellite studies of loci mapped within and outside the PWS/AS region, and fluorescence in situ hybridization (FISH) study, we confirmed the diagnosis in 35 patients: 27 with a paternal deletion, and 8 with maternal uniparental disomy (UPD). The clinical comparisons between deleted and UPD patients indicated that there were no major phenotype differences, except for a lower birth length observed in the UPD children. Our sample was composed of more girls than boys; UPD patients were diagnosed earlier than the deleted cohort (2(10/12) s. 7(9/12) years); and, in the deleted group, the boys were diagnosed earlier than the girls (5(2/12) vs. 7(8/12) years, respectively).

Heutinck, Lotte; Kampen, Nadine van; Jansen, Merel; Groot, Imelda J M de

2017-04-01

This study describes the amount of physical activity and perception of physical activity in boys with Duchenne muscular dystrophy (DMD) compared to healthy boys. A questionnaire described 6 domains of physical activity. Four Duchenne muscular dystrophy subgroups were made: early and late ambulatory, nonambulatory with relative good, or limited arm function. Eighty-four boys with Duchenne muscular dystrophy (15.0 ± 6.4 years) and 198 healthy boys (14.0 ± 4.3 years) participated. Daily activities were more passive for boys with Duchenne muscular dystrophy. Physical activity was less and low demanding compared to healthy boys. It decreased with disease severity ( P < .05), whereas screen time increased ( P < .05). Benefits of physical activity in boys with Duchenne muscular dystrophy were having fun and making friends. Barriers were lack of sport facilities and insufficient health. This study helps to quantify poor engagement in physical activity by boys with Duchenne muscular dystrophy, and demonstrates factors that contribute to it. Suggestions to stimulate physical activity are made.

Acute scrotum: is scrotal exploration the best management?

PubMed

Soccorso, G; Ninan, G K; Rajimwale, A; Nour, S

2010-09-01

Selective scrotal exploration of only those boys believed to have testicular torsion (TT), relying on history and clinical examination for diagnosis, can result in a missed or delayed diagnosis of TT. To minimise testicular loss we propose early scrotal exploration in all boys with acute scrotum (AS). To validate our approach we investigated the accuracy of clinical diagnoses of all boys with AS admitted to our unit. Clinical features and diagnoses were correlated with operative findings. A retrospective review of the records of all boys (1-16 years of age) presenting with AS between 2003 and 2007 was done. Overall, 138 boys were seen during this period. Three boys were treated conservatively. The 135 boys who underwent scrotal exploration were divided into three groups: Group A (47 boys) with a history and clinical features considered preoperatively to be consistent with torsion of appendix of testis (TAT); Group B (46 boys) whose characteristics were thought to be more consistent with TT; and finally Group C (42 boys) in whom a preoperative definitive diagnosis could not be made. The preoperative clinical features and diagnoses of the 135 boys were correlated with the operative findings. In Group A, exploration confirmed TAT in 37 (78%) boys, but in 7 (15%) boys it revealed TT. In Group B, exploration confirmed torsion in 31 (68%) boys, but 13 (28%) had TAT. In Group C, exploration revealed 39 (93%) cases of TAT and 3 (7%) cases of TT. Surgical exploration in all cases of paediatric AS offers an accurate diagnosis and treatment, thus minimising the risk of testicular loss. © Georg Thieme Verlag KG Stuttgart · New York.

Body fat and blood pressure: comparison of blood pressure measurements in Chinese children with different body fat levels.

Children in China are experiencing a rapid increase in the prevalence of obesity, which is associated with hypertension. To compare the effect of body fat on blood pressure (BP) with that of the normal physical growth, we compared BP levels in Chinese children with different body fat levels. In the present population-based study, 13 972 children in the highest-skinfold-thickness-quartile group were individually matched to 13 972 children in the lowest-skinfold-thickness-quartile group by height and weight. Similarly, 5103 children in the highest-waist-circumference-quartile group were matched to the same number of children in the lowest-waist-circumference-quartile group. The high- and low-fat groups had similar height and weight but the high-fat group had significantly higher skinfold and waist circumference measurements. The differences in systolic BP (SBP) between the high- and low-skinfold-thickness groups were small: 0·01 (95 % CI -0·41, 0·44) mmHg in boys and 0·20 (95 % CI -0·15, 0·54) mmHg in girls. The differences in diastolic BP (DBP) were also small (0·39 and 0·38 mmHg for boys and girls, respectively) but were statistically significant. The differences in both SBP and DBP between the high- and low-waist-circumference groups were small but not statistically significant. For a given body size as measured by height and weight, relative body fat had little impact on BP levels in these children. Fat mass and lean mass may have a similar quantitative impact on BP in healthy-weight children.

Obstructive internal hernia caused by mesodiverticular bands in children

PubMed Central

Bertozzi, Mirko; Melissa, Berardino; Magrini, Elisa; Di Cara, Giuseppe; Esposito, Susanna; Apignani, Antonino

2017-01-01

Abstract Introduction: The mesodiverticular band (MDB) is an embryologic remnant of the vitelline circulation, which carries the arterial supply to the Meckel diverticulum. In the event of an error of involution, a patent or nonpatent arterial band persists and extends from the mesentery to the apex of the antimesenteric diverticulum. This creates a snare-like opening through which bowel loops may herniate and become obstructed. This report describes 2 rare cases of small bowel occlusion owing to an internal hernia caused by a MDB. Cases: Case 1 was a 5-year-old boy who presented to our Emergency Department with colicky abdominal pain diffused to all abdominal quadrants. He also had 5 episodes of emesis, the last with bilious vomiting. Case 2, a 12-year-old boy, presented to our Emergency Department complaining of colicky abdominal pain. He had 2 episodes of nonbilious emesis. On physical examination, both children showed distension and tenderness of the abdomen and abdominal x-ray and ultrasound confirmed an occlusive picture without an apparent etiology. In case 1, an urgent laparotomy was performed and the MDB was ligated and cut, whereas in case 2 diagnosis and excision were performed in laparotomy. In both patients, there was a positive clinical evolution. Conclusion: Although MDB causing internal hernia is very rare, it should be considered in patients with a clinical picture of small bowel obstruction. In these cases, early surgery is important to prevent strangulation and gangrene of the bowel and to avoid dramatic events. Moreover, laparoscopy seems a safe and effective technique in these patients, especially in children with mild abdominal distention without surgical or trauma history, highlighting that further studies on the value of laparoscopy for the treatment of small bowel obstruction in pediatric patients are urgently needed.

Little is known of the acceptability of male circumcision (MC) to adolescent boys, a key target group for HIV prevention. We conducted a cluster design survey among adolescent boys and their parents/guardians in two villages in Botswana. Of 1300 households visited, 398 boys were eligible; 269 boys and 210 parents/guardians participated. MC was described correctly by 80% of boys, and 76% identified that MC reduces the risk of male HIV acquisition. After a brief informational session, 75% of boys stated that they would definitely want to be circumcised and 96% of parents/guardians would want their boy circumcised. Boys most frequently reported pain (49%) and possible health problems (19%) as concerns undergoing MC; concerns about peer or partner acceptance, sexual function, or cultural appropriateness were uncommon. Adolescent MC is likely to be highly acceptable in Botswana if done safely, for free and with adequate pain control in a hospital setting. PMID:21437725

This study was done to compare families of boys or of girls for actor and partner effect of stress, depression and parent-adolescent communication as perceived by mother, father and adolescent on adolescents' suicidal ideation. Participants were 183 families (104 boys' families, 79 girls' families) who met eligibility criteria. All measures were self-administered. Data were analyzed using SPSS 18.0 and AMOS 18.0 program. In boys' families, boys' depression and communication with father showed actor effect on boys' suicidal ideation. Boys' stress showed indirect effect on boys' suicidal ideation through communication with father and boys' depression. Mothers' depression showed indirect partner effect on boys' suicidal ideation through boys' depression. In families of girls, girls' depression and stress showed actor effects on girls' suicidal ideation. Girls' communication with mother showed indirect effects through girls' depression. Also girls' stress showed indirect effect through girls' depression. Stress in mothers and/or fathers showed partner effect on girls' suicidal ideation. To intervene in adolescents' suicidal ideation and promote adolescents' mental health, programs should be developed differently according to gender and based on parent's psychological states.

2005-09-01

To determine if differences existed in mothers' and fathers' perceptions of their sons' weight, controlling child-feeding practices (ie, restriction, monitoring, and pressure to eat), and parenting styles (ie, authoritarian, authoritative, and permissive) by their sons' body mass index (BMI). One person (L.S.B.) interviewed mothers and boys using validated questionnaires and measured boys' weight and height; fathers completed questionnaires independently. Subjects were white, preadolescent boys and their parents. Boys were grouped by their BMI into an average BMI group (n=25; BMI percentile between 33rd and 68th) and a high BMI group (n=24; BMI percentile > or = 85th). Multivariate analyses of variance and analyses of variance. Mothers and fathers of boys with a high BMI saw their sons as more overweight (mothers P=.03, fathers P=.01), were more concerned about their sons' weight (P<.0001, P=.004), and used pressure to eat with their sons less often than mothers and fathers of boys with an average BMI (P<.0001, P<.0001). In addition, fathers of boys with a high BMI monitored their sons' eating less often than fathers of boys with an average BMI (P=.006). No differences were found in parenting by boys' BMI groups for either mothers or fathers. More controlling child-feeding practices were found among mothers (pressure to eat) and fathers (pressure to eat and monitoring) of boys with an average BMI compared with parents of boys with a high BMI. A better understanding of the relationships between feeding practices and boys' weight is necessary. However, longitudinal research is needed to provide evidence of causal association.

Technology Education in South Africa: Evaluating an Innovative Pilot Project

NASA Astrophysics Data System (ADS)

Stables, Kay; Kimbell, Richard

2001-02-01

Researchers from Goldsmiths College were asked to undertake an evaluation of a three year curriculum initiative introducing technology education, through a learner-centred, problem solving and collaborative approach. The program was developed in a group of high schools in the North West Province of South Africa. We visited ten schools involved in the project and ten parallel schools not involved who acted as a control group. We collected data on student capability (demonstrated through an innovative test activity) and on student attitudes towards technology (demonstrated in evaluation questionnaires and in semi-structured interviews). Collectively the data indicate that in areas of knowledge and skill and in certain aspects of procedures (most notably problem solving) the project has had a marked impact. We also illustrate that greater consideration could have been given in the project to developing skills in generating and developing ideas and in graphic communication. Gender differences are noted, particularly in terms of positive attitudes illustrated by both boys and girls from schools involved in the project. Attention is drawn to the critical impact the project has had on transforming the pedagogy of the teachers from a teacher-centred didactic model, to a learner-centred, problem solving model. Some wider implications of the successes of this project are debated.

Objective To compare the long-term effectiveness and cost-effectiveness of 3 approaches to managing elevated blood pressure (BP) in adolescents in the United States: no intervention, “screen-and-treat,” and population-wide strategies to lower the entire BP distribution. Study design We used a simulation model to combine several data sources to project the lifetime costs and cardiovascular outcomes for a cohort of 15-year-old U.S. adolescents under different BP approaches and conducted cost-effectiveness analysis. We obtained BP distributions from the National Health and Nutrition Examination Survey 1999–2004 and used childhood-to-adult longitudinal correlation analyses to simulate the tracking of BP. We then used the coronary heart disease policy model to estimate lifetime coronary heart disease events, costs, and quality-adjusted life years (QALY). Results Among screen-and-treat strategies, finding and treating the adolescents at highest risk (eg, left ventricular hypertrophy) was most cost-effective ($18 000/QALY [boys] and $47 000/QALY [girls]). However, all screen-and-treat strategies were dominated by population-wide strategies such as salt reduction (cost-saving [boys] and $650/ QALY [girls]) and increasing physical education ($11 000/QALY [boys] and $35 000/QALY [girls]). Conclusions Routine adolescents BP screening is moderately effective, but population-based BP interventions with broader reach could potentially be less costly and more effective for early cardiovascular disease prevention and should be implemented in parallel.

ABSTRACT Objective: To evaluate the lifestyle indicators associated with cardiorespiratory fitness in adolescents from Ilhabela, São Paulo, Brazil. Methods: The sample consisted of 181 adolescents (53% male) from the Mixed Longitudinal Project on Growth, Development, and Physical Fitness of Ilhabela. Body composition (weight, height, and body mass index, or BMI), school transportation, time spent sitting, physical activity, sports, television time (TV), having a TV in the bedroom, sleep, health perception, diet, and economic status (ES) were analyzed. Cardiorespiratory fitness was estimated by the submaximal progressive protocol performed on a cycle ergometer. Linear regression models were used with the stepwise method. Results: The sample average age was 14.8 years, and the average cardiorespiratory fitness was 42.2 mL.kg-1.min-1 (42.9 for boys and 41.4 for girls; p=0.341). In the total sample, BMI (unstandardized regression coefficient [B]=-0.03), height (B=-0.01), ES (B=0.10), gender (B=0.12), and age (B=0.03) were significantly associated with cardiorespiratory fitness. In boys, BMI, height, not playing any sports, and age were significantly associated with cardiorespiratory fitness. In girls, BMI, ES, and having a TV in the bedroom were significantly associated with cardiorespiratory fitness. Conclusions: Lifestyle indicators influenced the cardiorespiratory fitness; BMI, ES, and age influenced both sexes. Not playing any sports, for boys, and having a TV in the bedroom, for girls, also influenced cardiorespiratory fitness. Public health measures to improve lifestyle indicators can help to increase cardiorespiratory fitness levels. PMID:28977318

Students' Experience of Working with Socioscientific Issues - a Quantitative Study in Secondary School

NASA Astrophysics Data System (ADS)

Ottander, Christina; Ekborg, Margareta

2012-12-01

This research project aims to investigate how students in lower secondary school experience work with socioscientific issues (SSI). The six socioscientific cases developed and used in this project are relevant according to characteristics of SSI and to the national curriculum. Approximately 1,500 students in Sweden have worked with one SSI case chosen by the teachers. A questionnaire-based instrument was used to measure the affective domain of students' attitudes towards and interest in science before starting to work with the case and a second questionnaire after finishing a case. The second student questionnaire, measured the situational characteristics of the SSI work and perceived cognitive and affective outcomes. According to the students' self-reported experience, all cases were interesting and related to a current issue. Most cases were equally interesting to boys and girls, the only exception was You are what you eat, which girls found more interesting than boys did. Almost all students claim that they learnt new facts, learnt to argue for their standpoint and to search and evaluate information during the work with the cases. The girls' average scores were higher on several aspects of learning outcomes. Furthermore the students, especially the girls, perceived that the outcome of working with SSI had relevance for their future, with some cases more relevant than others. The more interesting the student found the case, the more they claimed they learnt. The students do not, however, claim that they learnt more science than during ordinary lessons.

To examine 5-year longitudinal associations between family meal frequency and disordered eating behaviors in adolescents. Longitudinal study. Participants from 31 Minnesota schools completed in-class assessments in 1999 (time 1) and mailed surveys in 2004 (time 2). Adolescents (N=2516) who completed Project EAT (Eating Among Teens)-I (time 1) and -II (time 2) assessments. Time 1 family meal frequency and time 2 disordered eating behaviors, including extreme weight control behaviors (self-induced vomiting and use of laxatives, diet pills, or diuretics), less extreme unhealthy weight control behaviors (eating very little, fasting, using food substitutes, skipping meals, or smoking), binge eating, and chronic dieting. Among adolescent girls, time 1 regular family meals (> or = 5 meals/wk) were associated with lower prevalences of time 2 extreme weight control behaviors (odds ratio, 0.71; 95% confidence interval, 0.52-0.97), even after adjusting for sociodemographic characteristics, body mass index, family connectedness, parental encouragement to diet, and extreme weight control behaviors at time 1. Associations with other disordered eating behaviors were also suggestive of a protective effect of family meals in unadjusted analyses but were not statistically significant in adjusted analyses. Among adolescent boys, regular family meals did not predict lower levels of disordered eating behaviors. The high prevalence of disordered eating behaviors among adolescent girls and the protective role of family meals suggest a need for interventions aimed at promoting family meals. Further exploration of predictors of disordered eating behaviors in adolescent boys and the role of family meals is warranted.

Churg-Strauss syndrome (CSS) is a granulomatous small vessel vasculitis. It is characterized by asthma, allergic granulomatosis and vasculitis. This syndrome is rare in children. A 5 years old boy was admitted with cough, fever and dyspnea for 2 weeks. On the basis of laboratory data (peripheral eosinophilia), associated with skin biopsy, and history of CSS in his sister, this disease was eventually diagnosed. The patient had good response to corticosteroid. In every asthmatic patient with prolonged fever, eosinophilia and multisystemic involvment, CSS should be considered.

Uhran, Mark L.; Timm, Marc G.

1993-01-01

The deployment and permanent operation of Space Station Freedom will enable researchers to enter a new era in the 21st century, in which continuous on-orbit experimentation and observation become routine. In support of this objective, the Space Station Freedom Program Office has initiated the Express Payload Project. The fundamental project goal is to reduce the marginal cost associated with small payload development, integration, and operation. This is to be accomplished by developing small payload accommodations hardware and a new streamlined small payload integration process. Standardization of small payload interfaces, certification of small payload containers, and increased payload developer responsibility for mission success are key aspects of the Express Payload Project. As the project progresses, the principles will be applied to both pressurized payloads flown inside the station laboratories and unpressurized payloads attached to the station external structures. The increased access to space afforded by Space Station Freedom and the Express Payload Project has the potential to significantly expand the scope, magnitude, and success of future research in the microgravity environment.

The purpose of this study was to validate derived T2 maps as an objective measure of muscular fat for discrimination between boys with Duchenne muscular dystrophy (DMD) and healthy boys. Forty-two boys with DMD (mean age, 9.9 years) and 31 healthy boys (mean age, 11.4 years) were included in the study. Age, body mass index, and clinical function scale grade were evaluated. T1-weighted MR images and T2 maps with and without fat suppression were obtained. Fatty infiltration was graded 0-4 on T1-weighted images, and derived T2 fat values (difference between mean T2 values from T2 maps with and without fat suppression) of the gluteus maximus and vastus lateralis muscles were calculated. Group comparisons were performed. The upper limit of the 95% reference interval of T2 fat values from the control group was applied. There was no significant difference in age or body mass index between groups. All healthy boys and 19 boys (45.2%) with DMD had a normal clinical function scale grade. Grade 1 fatty infiltration was seen in 90.3% (gluteus maximus) and 71.0% (vastus lateralis) of healthy boys versus 33.3% (gluteus maximus) and 52.4% (vastus lateralis) of boys with DMD. T2 fat values of boys with DMD were significantly longer than in the control group (p < 0.001). Using a 95% reference interval for healthy boys for the gluteus maximus (28.3 milliseconds) allowed complete separation from boys with DMD (100% sensitivity, 100% specificity), whereas the values for the vastus lateralis (7.28 milliseconds) resulted in 83.3% sensitivity and 100% specificity. Measurement of muscular fat with T2 maps is accurate for differentiating boys with DMD from healthy boys.

Evaluating Boy Scout Geology Education, A Pilot Study

NASA Astrophysics Data System (ADS)

Hintz, R. S.; Thomson, B.

2008-12-01

This study investigated geology knowledge acquisition by Boy Scouts through use of the Boy Scout Geology Merit Handbook. In this study, boys engaged in hands-on interactive learning following the requirements set forth in the Geology Merit Badge Handbook. The purposes of this study were to determine the amount of geology content knowledge engendered in adolescent males through the use of the Geology Merit Badge Handbook published by the Boy Scouts of America; to determine if single sex, activity oriented, free-choice learning programs can be effective in promoting knowledge development in young males; and to determine if boys participating in the Scouting program believed their participation helped them succeed in school. Members of a local Boy Scout Troop between the ages of 11 and 18 were invited to participate in a Geology Merit Badge program. Boys who did not already possess the badge were allowed to self-select participation. The boys' content knowledge of geology, rocks, and minerals was pre- and post-tested. Boys were interviewed about their school and Scouting experiences; whether they believed their Scouting experiences and work in Merit Badges contributed to their success in school. Contributing educational theories included single-sex education, informal education with free-choice learning, learning styles, hands-on activities, and the social cognitive theory concept of self-efficacy. Boys who completed this study seemed to possess a greater knowledge of geology than they obtained in school. If boys who complete the Boy Scout Geology Merit Badge receive additional geological training, their field experiences and knowledge acquired through this learning experience will be beneficial, and a basis for continued scaffolding of geologic knowledge.
