Association of leisure time physical activity and NMR-detected circulating amino acids in peripubertal girls: A 7.5-year longitudinal study
2017
AbstractThis study investigated the longitudinal associations of physical activity and circulating amino acids concentration in peripubertal girls. Three hundred ninety-six Finnish girls participated in the longitudinal study from childhood (mean age 11.2 years) to early adulthood (mean age 18.2 years). Circulating amino acids were assessed by nuclear magnetic resonance spectroscopy. LTPA was assessed by self-administered questionnaire. We found that isoleucine, leucine and tyrosine levels were significantly higher in individuals with lower LTPA than their peers at age 11 (p < 0.05 for all), independent of BMI. In addition, isoleucine and leucine levels increased significantly (~15%) fro…
When Adolescents with High Self-Concept Lose their Engagement in School // Cuando se pierde la motivación escolar de los adolescentes con mejor autoc…
2015
Engagement in school and self-concept are two main constructs to explain the school adjustment. To understand how engagement might change during adolescence, we analyzed early and middle adolescents’ engagement in school (cognitive, affective, behavioural, and personal agency) as a function of their level of self-concept. Participants were 685 adolescents, 296 males (43.2%) and 389 females between 11-17 years old. Among early adolescents, students with high self-concept always reported more cognitive, affective, behavioural, and personal agency engagement than students with low self-concept. However, among middle adolescents, students with high self-concept reported only higher affective an…
Long-Term Follow-Up of Children, Adolescents, and Young Adult Cancer Survivors.
2020
<b><i>Background and Summary:</i></b> Thanks to increasing cure rates to currently &#x3e;80%, children, adolescents, and young adults (CAYA) survive their cancer much more frequently today than decades ago. Due to their long life expectancy, CAYA cancer survivors are at a particular risk of long-term sequelae from the cancer itself or the therapy applied; this requires specific follow-up, and preventative or even therapeutic interventions. Thus, compared to the normal population, morbidity and mortality may be significantly increased. In 2 of 3 survivors, the cancer and the respective treatment can lead to late effects, even after 30 years, which require specific…
Craniomaxillofacial morphology alterations in children, adolescents and adults with neurofibromatosis 1 : a cone beam computed tomography analysis of…
2017
Background Oral manifestations are common in neurofibromatosis 1 (NF1), and include jaws and teeth alterations. Our aim was to investigate the craniomaxillofacial morphology of Brazilian children, adolescents and adults with NF1 using cone beam computed tomography. Material and Methods This study was conducted with 36 Brazilian individuals with NF1 with ages ranging from 4 to 75. The participants were submitted to anamnesis, extra and intraoral exam and cephalometric analysis using cone beam computed tomography. Height of the NF1 individuals was compared to the length of jaws and skull base. The results of the cephalometric measurements of the NF1 group were compared with a control group pa…
Why Comparative Research on the Middle Years?
2018
Anyone who has recently stepped into a middle years’ classroom knows all too well the truth of this portrait—the lived experience of learners in our schools today. Early adolescents are truly a unique group of learners, like none other a teacher might experience—a group that will at one moment test a teacher’s mettle and the very next bring so much elation and reward that a teacher might even question how they could ever think of working with another age group. This is the appeal and the true curiosity behind the early adolescent learner and is the heart of what we will present to you in this book.
Promoting emotional skills in early adolescents with mental health conditions in music therapy : a content analysis of focus group interviews
2023
Introduction: Music therapy is actively used with early adolescents in relation to their emotional skill development. Yet, the conceptualization of emotional skills is typically not systematically addressed in therapeutic practice. This study examined music therapists’ views on the progress of emotional skills when working with early adoles-cents with mental health conditions. The study also explored what kind of methods the therapists use with the target group, and the applicability of a previously pub-lished conceptual model. Method: We conducted a deductive-inductive content analysis of transcripts from four focus group interviews among 13 professional music therapists. Results: The ther…
Gendered pathways to young adult symptomatology
2016
The transition to adulthood is a critical juncture in the course of psychopathology. This study examined the ways in which earlier capacity to deal with relationship stress during adolescence contributed to an adaptive outcome in emerging adulthood. In a prospective study of 145 individuals, relationship stress, individual coping capacities, and perceived support from fathers, mothers, and peers were analyzed, when the participants were 13 and 17 years old. The effects of these earlier capacities to deal with relationship stress on health outcomes were examined in young adulthood (age 23). Gendered pathways to young adults’ symptomatology emerged. Females experiencing earlier relationship …
Confirmatory factor analysis and psychometric properties of the Spanish version of the Multidimensional Body-Self Relations Questionnaire-Appearance …
2015
The main aim of this study was to confirm the factorial structure of the Spanish version of the Multidimensional Body-Self Relations Questionnaire-Appearance Scales in early adolescents from 12 to 14 years. The sample included 355 participants, 189 girls and 166 boys, with ages ranging from 12 to 14 years old. The original MBSRQ-AS 5-factor structure was confirmed, and the model showed a good fit to the data: Appearance Evaluation, Appearance Orientation, Body Areas Satisfaction, Overweight Preoccupation, and Self-Classified Weight. The internal consistency of the test scores was adequate. Girls had higher score s than boys on Appearance Orientation, Overweight Preoccupation, and Self-Class…
A Revised Short Form of the Extended Class Play Among Italian Early Adolescents
2019
Among the measures assessing peer reputation, the Extended Class Play (ECP) is now used extensively in North American settings. Little information is available in other cultural contexts. Furthermore, practical considerations suggest developing a shorter form of the ECP to be used in socio-educational environments. This study examined the ECP dimensions of peer assessment in Italy as well as developed a shorter form of the measure. We revised the ECP using factor analyses according to an explorative-confirmatory approach. The original 37-item ECP was shortened to a 22-item version and, subsequently, the properties of the revised measure were evaluated. We performed two studies comprising, r…
Effects of acute bupropion administration on locomotor activity in adolescent and adult mice
2005
Responses to some psychoactive substances seem to differ between adolescents and adults. Bupropion, an antidepressant which is also used for smoking cessation, induces a dose-dependent increase in locomotor activity in adult mice, although its behavioral actions in adolescents have not been evaluated. In the present study the effects of acute bupropion administration (5, 10, 15 and 20 mg/kg) on locomotor activity were examined in early adolescent (postnatal day (pnd): 29-31 days), late adolescent (pnd: 47-49 days) and adult (pnd > 70 days) male NMRI mice, using an infrared photocell system. Locomotion was recorded for a total period of 90 min. Results indicated that there were significant d…
