3-year follow-up results of bone mineral content and density after a school-based physical activity randomized intervention trial.

BACKGROUND: As an important modifiable lifestyle factor in osteoporosis prevention, physical activity has been shown to positively influence bone mass accrual during growth. We have previously shown that a nine month general school based physical activity intervention increased bone mineral content (BMC) and density (aBMD) in primary school children. From a public health perspective, a major key issue is whether these effects persist during adolescence. We therefore measured BMC and aBMD three years after cessation of the intervention to investigate whether the beneficial short-term effects persisted. METHODS: All children from 28 randomly selected first and fifth grade classes (intervention group (INT): 16 classes, n=297; control group (CON): 12 classes, n=205) who had participated in KISS (Kinder-und Jugendsportstudie) were contacted three years after cessation of the intervention program. The intervention included daily physical education with daily impact loading activities over nine months. Measurements included anthropometry, vigorous physical activity (VPA) by accelerometers, and BMC/aBMD for total body, femoral neck, total hip, and lumbar spine by dual-energy X-ray absorptiometry (DXA). Sex- and age-adjusted Z-scores of BMC or aBMD at follow-up were regressed on intervention (1 vs. 0), the respective Z-score at baseline, gender, follow-up height and weight, pubertal stage at follow-up, previous and current VPA, adjusting for clustering within schools. RESULTS: 377 of 502 (75%) children participated in baseline DXA measurements and of those, 214 (57%) participated to follow-up. At follow-up INT showed significantly higher Z-scores of BMC at total body (adjusted group difference: 0.157 units (0.031-0.283); p=0.015), femoral neck (0.205 (0.007-0.402); p=0.042) and at total hip (0.195 (0.036 to 0.353); p=0.016) and higher Z-scores of aBMD for total body (0.167 (0.016 to 0.317); p=0.030) compared to CON, representing 6-8% higher values for children in the INT. No differences could be found for the remaining bone parameters. For the subpopulation with baseline VPA (n=163), effect sizes became stronger after baseline VPA adjustment. After adjustment for baseline and current VPA (n=101), intervention effects were no longer significant, while effect sizes remained the same as without adjustment for VPA. CONCLUSION: Beneficial effects on BMC of a nine month general physical activity intervention appeared to persist over three years. Part of the maintained effects may be explained by current physical activity.

Problematizações do currículo-experiência no entre-lugar da educação infantil e do ensino fundamental : possíveis contribuições para o ensino fundamental de nove anos

Esse texto é um convite para discutir alguns atravessamentos colocados nas escolas a partir da implementação e implantação do Ensino Fundamental de Nove Anos, como política de governo reorganiza os espaçostempos da escola, impõe um currículo prescrito, uma avaliação por objetivos e coloca em discussão o que é ser criança e viver a infância na escola. Como objetivo principal, busca problematizar o processo de implementação e implantação do Ensino Fundamental de Nove Anos no município de Vitória-ES e suas implicações no entre-lugar da Educação Infantil e Ensino Fundamental. Para tanto foi necessário estar no cotidiano escolar, viver, sentir e conversar com os sujeitos praticantes: as criançasalunos; as professoras e as pedagogas. Nesse sentido, três movimentos foram realizados: o primeiro movimento consiste em um levantamento de dados documentais, pareceres, leis, diretrizes no âmbito nacional e municipal que determinaram a obrigatoriedade do Ensino Fundamental de Nove Anos; o segundo movimento consiste em trazer para análise alguns artigos publicados na Associação Nacional de Pós-Graduação e Pesquisa em Educação (ANPED) em quatro Grupos de Trabalho (GT) que abordam o tema “Ensino Fundamental de Nove Anos”, e também textos que circulam nas escolas e que foram organizados pelo Ministério da Educação e Cultura (MEC); o terceiro movimento consiste na pesquisa realizada em um Centro Municipal de Educação Infantil (CMEI) e em uma Escola Municipal de Ensino Fundamental (EMEF) no município de Vitória, no decorrer dos anos de 2011 e 2012, onde foi possível conversar com as criançasalunos de duas turmas do 1º ano, com as professoras e pedagogas. Utiliza como aporte teórico-metodológico as pesquisas nos/dos/com os cotidianos (CERTEAU 1994; ALVES 2001; FERRAÇO 2003) onde foi possível a apropriação de diferentes instrumentos de pesquisa, como: o diário de campo, recurso importante na intenção de capturar movimentos, falas e expressões; as conversas como tentativa de aproximação com os sujeitos para um fazer com e as oficinas de literatura como dispositivo de criação e produção de outros modos de pensar a criança e a infância. Na tentativa de discutir o lugar da criança no Ensino Fundamental de Nove Anos o conceito de devir-criança de Deleuze (1997) ajuda a pensar no movimento da criança como presença potente que produz outros modos de vida mais belos e intensos na escola e no currículo. O conceito de entre-lugar de Bhabha (2007) fortalece as discussões entre CMEI e EMEF como espaçostempos de negociações. As discussões de Kohan (2003) colocam em debate o lugar da infância que não indica um tempo cronológico, mas pensa em um encontro com a infância, com a experiência da infância. E Larrosa (2004) que com o conceito de experiência nos ajuda a pensar em um currículo-experiência, currículo esse que não está localizado no documento prescrito, nos espaçostempos da Educação Infantil ou do Ensino Fundamental, também não se localiza na criança, ou em uma dada infância, mas na composição com a escola, com as crianças, com as infâncias e isso só é possível no encontro com a criança que existe em nós.

Elevated blood pressure prevalence in children did not follow the increase in overweight: results from a school-based study in a rapidly developing country, 1998-2006

Background: Blood pressure (BP) is strongly associated with body weight and there is concern that the pediatric overweight epidemic could lead to an increase in children's mean BP. Objectives: We analyzed BP trends from 1998 to 2006 among children of the Seychelles, a rapidly developing middle-income country in Africa. Methods: Serial school-based surveys of weight, height and BP were conducted yearly between 1998-2006 among all students of the country in four school grades (kindergarten, 4th, 7th and 10th years of compulsory school). We used the CDC criteria to define "overweight" (BMI _95th sex-, and age-specific percentile) and the NHBPEP criteria for "elevated BP" (BP _95th sex-, age-, and height specific percentile). Methods for height, weight, and BP measurements were identical over the study period. The trends in mean BMI and mean systolic/diastolic BP were assessed with linear regression. Results: 27,703 children aged 4-18 years (participation rate: 79%) contributed 43,927 observations on weight, height, and BP. The prevalence of overweight increased from 5.1% in 1998-2000 to 8.1% in 2004-2006 among boys, and from 6.1% to 9.1% among girls, respectively. The prevalence of elevated BP was 8.4% in 1998-2000 and 6.9% in 2004-2006 among boys; 9.8% and 7.8% among girls, respectively. Over the 9-years study period, age-adjusted body mass index (BMI) increased by 0.078 kg/m2/year in boys and by 0.083 kg/m2/year in girls (both sexes, P_0.001). Age- and height-adjusted systolic BP decreased by -0.37 mmHg/year in boys and by -0.34 mmHg/year in girls (both sexes, P_0.001). Diastolic BP did not change in boys (-0.02 mmHg/year, P: 0.40) and slightly increased in girls (0.07 mmHg/year, P: 0.003). These trend estimates were altered modestly upon further adjustment for BMI or if analyses were based on median rather than mean values. Conclusion: Although body weight increased markedly between 1998 and 2006 in this population, systolic BP decreased and diastolic BP changed only marginally. This suggests that population increases in body weight are not necessarily associated with corresponding rises in BP in children.

School burnout in adolescents : Differences in background variables and exploration of school-related stress at the end of compulsory schooling

The aim of this study is to contribute to a better understanding of the risk factors associated with school burnout, which has recently been described as a syndrome of emotional exhaustion due to school demands, cynical and detached attitude towards school and feelings of inadequacy as a student (Salmela-Aro, Kiuru, Pietikainen & Jokela, 2008a). The research focuses on students in the last years of compulsory schooling, period in which burnout has not received much attention yet. A total of 342 adolescents (Mean age = 14.84) were asked to complete questionnaires about school burnout, school-related stress and background variables. The results showed differences in school burnout by gender, grade level and school track, with girls, last grade of compulsory school and high-track classes, showing the highest scores. No difference was observed with respect to grade retention. Several types of school stress were identified, with stress type Success related to pressures to succeed and concerns about the academic future being the highest. Finally, stress and burnout were strongly and positively correlated, and the type of stress Success was the best predictor of overall Burnout, Exhaustion and Inadequacy dimension scores. The results are discussed in relation to their theoretical relevance and implications for the prevention of school burnout in adolescents.

From the Reliable and Unselfish to the Versatile and Independent : - desired qualities in two Swedish curricula

The process in which girls and boys are constructed and construct themselves to pupils takes place in a context where conceptions of “the good pupil” are distinctly manifested in national school documents. In different types of texts concerning school and education, the image of the pupil that society wants to create emerges. Documents from early childhood education up to university level prioritise qualities such as independence, initiative, accountability and freedom to make ones own choices. Qualities or competencies that are preferred during a certain period change as time passes and society develops. The idea of the democratic subject is not the same today as it was 25 years ago. The purpose of this article is to emphasise and compare different desired qualities described in two Swedish national curricula, competencies that pupils in the compulsory school are supposed to develop. The discussion encompasses the political ideas of the pupil during a period of twenty-five years in light of changes in Western societies during the last decades.

Infância e escola: desafios no ingresso da criança no ensino fundamental

In order to expand educational services in the country, were recently approved laws that changed the organization of schools and the population served by them, as was the case of Law No. 11.274/2006 elementary school that extended from eight to nine years, establishing the admission of children to this level of education to 6 years old. The research aimed to analyze the relationship between the legal text and the meanings of schooling and the specifics of childhood with the entry of children in elementary school. We proceeded to carry out theoretical research and documentation and with the main results we can state that: 1) referring to the childhood and school education, we can reflect on the period that includes the ages between 5 and 7 years, periods in which the child Brazil, according to new legislation can be met in kindergarten and compulsory from 6 years in elementary education, refers to the student at a time conducive to the psychological and cognitive investment in the development of imagination, thought through images, perception , logical reasoning, comparison and identification of elements of the property, creativity and playful and symbolic creations, 2) found that the formation of the 1st child. years of elementary school students is directed around the practices of literacy, with emphasis on the acquisition of reading and writing; Find out what this new educational context, schools are presenting great challenges due to the specifics of care for children six years in the first year Elementary School, showing gap between the law and the actual developments in the reorganization of schools.

The role of chance events in the school-to-work transition: The influence of demographic, personality and career development variables

Chance events are considered important in career development, yet little empirical research is available on their predictors and consequences. The present study investigated socio-demographic (gender, nationality, school-type), personality (openness, locus of control) and career development variables (career decidedness, career planning) in relation to perceived chance events with a retrospective (N = 229, eleventh grade), and 1-year longitudinal prospective study (N = 245, eighth/ninth grade) among Swiss adolescents. The results showed that the majority of both groups reported a significant influence of chance events on their transition from compulsory school to vocational education or high school. Importance of chance events related to socio-demographics and personality but not career preparation. Career preparation and chance events predicted subjective career success in terms of wish correspondence and overall satisfaction with transition outcome among the younger cohort. Implications include the necessity to integrate both thorough career preparation and chance events in theory and counseling practice.

Estimation of the Proportion of Underachieving Students in Compulsory Secondary Education in Spain: An Application of the Rasch Model

There are very few studies in Spain that treat underachievement rigorously, and those that do are typically related to gifted students. The present study examined the proportion of underachieving students using the Rasch measurement model. A sample of 643 first-year high school students (mean age = 12.09; SD = 0.47) from 8 schools in the province of Alicante (Spain) completed the Battery of Differential and General Skills (Badyg), and these students' General Points Average (GPAs) were recovered by teachers. Dichotomous and Partial credit Rasch models were performed. After adjusting the measurement instruments, the individual underachievement index provided a total sample of 181 underachieving students, or 28.14% of the total sample across the ability levels. This study confirms that the Rasch measurement model can accurately estimate the construct validity of both the intelligence test and the academic grades for the calculation of underachieving students. Furthermore, the present study constitutes a pioneer framework for the estimation of the prevalence of underachievement in Spain.

American or British English? : Attitudes towards English dialects among Swedish pupils

The two major varieties of English are American and British English. In Swedish compulsory school both varieties are taught. This essay examines the preferences and attitudes of pupils in 9th grades towards the two varieties, and if there are any gender differences. Previous research has shown that pupils are becoming more and more positive towards American English than they have been in earlier studies. This essay is based on a quantitative study carried out through questionnaires handed-out to 84 9th graders. The results show that the pupils prefer American English in speaking and for educational purposes. However, British English is viewed as more intelligent, professional, beautiful and correct. These findings mostly correspond to previous research but also show some contrasting features such as pupils wanting to speak British English rather than American English.

A universally delivered CBT based intervention in a Scottish secondary school: a pilot feasibility study

Objectives: To evaluate the feasibility of a universally delivered CBT-based programme for pupils within a Scottish secondary school setting. Design: A pre-post, within and between groups design was utilised. Setting: Religious Moral Citizenship and Education (RMCE) classes in a Scottish secondary school. Participants: Four (n = 103) classes of third year secondary school pupils were arbitrarily allocated to two conditions: RMCE-as usual (RMCE-AU) controls, and LLTTF intervention. Intervention: Living Life to the Full (LLTTF) is a series of Cognitive Behavioural Therapy (CBT)-based booklets and accompanying 8 classes to improve coping skills. An adolescent version of LLTTF was recently developed. This was delivered over nine weeks by school teachers trained in the approach. Outcome measures: The Strengths and Difficulties Questionnaire, Rosenberg Self-Esteem scale, General Self-Efficacy Scale, and Locus of Control scale were administered at baseline and 9 week follow-up. To determine acceptability and utility of the materials course feedback was gathered weekly from the intervention group and a focus group (n=5) was conducted at 3 month follow up. Results: Outcome measures showed no significant improvement in overall wellbeing of those in the intervention group compared with that of the control group. Weekly feedback suggested that the majority of pupils found the materials useful and relevant. Focus group feedback suggested that pupils found the intervention useful, had utilised strategies in everyday life and would welcome recurring provision of such interventions within the school setting. Conclusions: Universally delivered CBT intervention is acceptable and feasible within the secondary school environment. However, objective measurement using standardised tools does not adequately corroborate qualitative feedback from pupils. Issues relating to measurement, study design and implementation of future interventions are discussed.

Teen Triple P: A universal approach to reducing risk factors for behavioural and emotional problems in adolescents at the transition to high school

Teen Triple P is a multilevel system of intervention that is designed to provide parents with specific strategies to promote the positive development of their teenage children as they make the transition into high school and through puberty. The program is based on a combination of education about the developmental needs of adolescents, skills training to improve communication and problem-solving, plus specific modules to deal with common problems encountered by parents and adolescents that can escalate into major conflict and violence. It is designed to increase the engagement of parents of adolescent and pre-adolescent children by providing them with easy access to evidencebased parenting advice and support. This paper presents data collected as part of a survey of over 1400 students in first year high school at 9 Brisbane schools. The survey instrument was constructed to obtain students' reports about behaviour which is known to be associated with their health and wellbeing, and also on the extent to which their parents promoted or discouraged such behaviour at home, at school, and in their social and recreational activities in the wider community. Selected data from the survey were extracted and presented to parents at a series of parenting seminars held at the schools to promote appropriate parenting of teenagers. The objectives were to provide parents with accurate data about teenagers' behaviour, and about teenagers' reports of how they perceived their parents' behaviour. Normative data on parent and teenager behaviour will be presented from the survey as well as psychometric data relating to the reliability and validity of this new measure. Implications of this strategy for increasing parent engagement in parenting programs that aim to reduce behavioural and emotional problems in adolescents will be discussed.

Prevalence of dental wear among 12-year-old Brazilian adolescents using a modification of the tooth wear index

Objective. This study investigated the prevalence of dental wear in 12-year-old adolescents using a modification of the tooth wear index (TWI). The modifications were proposed in order to fit with the World Health Organization standard, thus allowing application of the index in broad epidemiological surveys. Study design: An epidemiological cross-sectional survey was performed by trained, calibrated examiners, using a modified version of the TWI. Methods: Urban elementary schools were chosen because they provide a fair representation of the city`s population in terms of socio-economic status. The sample included 295 adolescents, selected randomly and systematically. Dental wear was assessed by calibrated examiners (kappa > 0.85), using a modified version of the TWI. This modified version includes a code for teeth restored due to wear, and another code for teeth that cannot be assessed. In addition, it does not differentiate the depth of dentine involvement. Proportions and confidence intervals were used to describe the prevalence of dental wear. Mann-Whitney test was used to detect differences in the degree of dental wear between mates and females. The level of statistical significance was set at 5%. Results: In total, 24,780 dental surfaces were evaluated. Among these surfaces, 73.10% did not present dental wear, 24.10% had incipient lesions, 2.46% had moderate lesions and 0.34% had been restored. No severe lesions were detected. Tooth wear was mainly seen on the occlusal/incisal surfaces (26.55%), involving enamel or enamel-dentine, but not the secondary dentine or pulp. The prevalence of dental wear was 26.90%. Considering the different teeth, wear was present in 53.22% of incisors, 50.51% of canines, 10.17% of premolars and 10.85% of molars. The prevalence of the different degrees of dental wear was similar in mates and females (P > 0.05). Conclusion: The modified TWI seems to bean effective toot for use in broad epidemiological surveys, due to easier calibration and high reproducibility rates.

A perceção das crianças sobre o trabalho prático e seu contributo nas aprendizagens

Relatório apresentado à Escola Superior de Educação de Lisboa para obtenção do grau de mestre em Ensino do 1.º e do 2.º Ciclo do Ensino Básico
