Kroppsbilde og slankefokus blant fysisk aktive gutter i ungdomsskolen og på videregående skole i Norge :
2016
Masteroppgave i idrettsvitenskap - Universitetet i Agder 2016 The aim of this study was to investigate body image and drive for thinness among adolescent boys, and to examine variations for these variables in age and level of physical activity. This cross-sectional study is part of “the Relevance of Physical Activity Contexts in Every-Day Life of Adolescents” (REPAC), which is a larger project. 1423 boys from secondary school (8th grade) and upper secondary school (11th grade) were included in this study, and these responded to a questionnaire that was developed to examine how different activity contexts affected adolescent boys everyday lives. Correlation analysis and one-way ANOVA tests w…
Effects of school-based interventions on motivation towards physical activity in children and adolescents: Protocol for a systematic review
2019
Background Recent studies have observed low levels of physical activity in children and adolescents worldwide. Physical activity interventions are increasingly carried out to counteract this development. The school environment is an ideal setting for such interventions to take place as large numbers of children and adolescents can be addressed. With the assumption that motivation is the key to initiate and sustain beneficial health behaviors, theory-based intervention studies apply motivational strategies to increase students’ participation in physical activity. The main objective of this systematic review will be to analyze the effects of school-based physical activity interventions on a v…
Effects of school-based interventions on motivation towards physical activity in children and adolescents: A systematic review and meta-analysis
2020
Introduction Assuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents. Methods A comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation…
Susumu Hani (1950-1960): la aportación teórico-práctica al documental y al cine juvenil japonés. Una aproximación al caso de Hani como precursor de l…
2015
RESUMEN La tesis reúne por primera vez una antología del director japonés Susumu Hani. En ella, se saca a la luz diecisiete de sus documentales realizados en los estudios Iwanami Eiga entre 1950 y 1960 para cine y televisión, en su mayoría desconocidos en Occidente. El análisis de estas obras se acompaña con las lecturas de los ensayos originales escritos por Hani, que se ponen en el contexto de las discusiones teóricas que tuvieron lugar en el Japón de la época. La PARTE 1 trata de la aportación teórico-práctica de Hani al cine de no ficción. El Apartado 1.1 es un recorrido por los debates en los que participó respecto al documental de vanguardia, el realismo (recuperando el enfrentamiento…
Teacher-rated aggression and co-occurring behaviors and emotional problems among schoolchildren in four population-based European cohorts
2021
Aggressive behavior in school is an ongoing concern. The current focus is on specific manifestations such as bullying, but the behavior is broad and heterogenous. Children spend a substantial amount of time in school, but their behaviors in the school setting tend to be less well characterized than at home. Because aggression may index multiple behavioral problems, we used three validated instruments to assess means, correlations and gender differences of teacher-rated aggressive behavior with co-occurring externalizing/internalizing problems and social behavior in 39,936 schoolchildren aged 7-14 from 4 population-based cohorts from Finland, the Netherlands, and the UK. Correlations of aggr…
Analysis of Personal and Family Factors in the Persistence of Attention Deficit Hyperactivity Disorder: Results of a Prospective Follow-Up Study in C…
2015
Objectives To study the course of ADHD during childhood and analyze possible personal and family predictor variables of the results. Method Sixty-one children with ADHD who were between 6 and 12 years old at the baseline assessment were evaluated 30 months later (mean age at baseline: 8.70 ± 1.97; mean age at follow-up: 10.98 ± 2.19). Status of ADHD in follow-up was identified as persistent (met DSM-IV-TR criteria according to parents’ and teachers’ ratings), contextually persistent (met ADHD criteria according to one informant, and there was functional impairment) and remitted ADHD (with subthreshold clinical symptomatology). Associated psychological disorders of the three groups were anal…
Behavioural correlates of early-treated congenital hypothyroidism
2007
Parents' and teachers' ratings were used to evaluate the behavioural characteristics of children with early-treated congenital hypothyroidism (CH). Comparisons were made between 63 children with early-treated CH and 34 healthy controls at the ages of 7.5 and 9.5 y. Additional comparisons were made between the two largest CH subgroups (thyroid agenesis, thyroid dysgenesis) and controls. The most marked differences were found on the introversion cluster and the motor clumsiness scale within it. Children with CH, particularly those with thyroid agenesis, showed introversion and motor clumsiness rather than social negativity and inattention. It is suggested that this behavioural profile may wel…
Management of undescended testes: European Association of Urology/European Society for Paediatric Urology Guidelines.
2016
Summary Context Undescended testis is the most common endocrinological disease in the male newborn period. Incidence varies between 1.0% and 4.6% in full-term neonates, with rates as high as 45% in preterm neonates. Failure or delay of treatment can result in reduced fertility and/or increased testicular cancer risk in adulthood. Objective To provide recommendations for the diagnosis and treatment of boys with undescended testes which reduce the risk of impaired fertility and testicular cancer in adulthood. Evidence acquisition Embase and Pubmed were searched for all relevant publications, from 1990 to 2015 limited to English language. Data were narratively synthesized in light of methodolo…
Predictability of oppositional defiant disorder and symptom dimensions in children and adolescents with ADHD combined type.
2010
BackgroundOppositional defiant disorder (ODD) is frequently co-occurring with attention deficit hyperactivity disorder (ADHD) in children and adolescents. Because ODD is a precursor of later conduct disorder (CD) and affective disorders, early diagnostic identification is warranted. Furthermore, the predictability of three recently confirmed ODD dimensions (ODD-irritable, ODD-headstrong and ODD-hurtful) may assist clinical decision making.MethodReceiver-operating characteristic (ROC) analysis was used in order to test the diagnostic accuracy of the Conners' Parent Rating Scale revised (CPRS-R) and the parent version of the Strength and Difficulties Questionnaire (PSDQ) in the prediction of …
Body weight dissatisfaction and communication with parents among adolescents in 24 countries: international cross-sectional survey
2009
Abstract Background Parents have significant influence on behaviors and perceptions surrounding eating, body image and weight in adolescents. The aim of this study was to examine the prevalence of body weight dissatisfaction, difficulty in communication with the parents and the relationship between communication with parents and adolescents' dissatisfaction with their body weight (dieting or perceived need to diet). Methods Survey data were collected from adolescents in 24 countries and regions in Europe, Canada, and the USA who participated in the cross-sectional 2001/2002 Health Behaviour of School-Aged Children (HBSC) study. The association between communication with parents and body wei…
