Count- versus MAD-based accelerometry-assessed movement behaviors and associations with child adiposity and fitness
2021
usc Estimations of time spent sedentary and in various physical activity intensities may vary according to data reduction methods applied. This study compared associations between children's accelerometer data and adiposity and fitness markers using open source (mean amplitude deviation, MAD) and proprietary (counts) data reduction methods. Complete-case accelerometer, adiposity (Body Mass Index z-score, waist circumference), and fitness (cardiorespiratory, musculoskeletal) data from 118 children (10.4 ± 0.6 years, 49% girls) were analyzed. Estimates of sedentary behavior, light-, moderate-, vigorous- (VPA), and moderate- to vigorous-intensity (MVPA) physical activity were calculated using …
The "Invisible Children": Uncertain Future of Unaccompanied Minor Migrants in Europe.
2016
Because of their particular helpless condition, the unaccompanied minor migrants are at serious risk to be further deprived of their rights, and to become de facto “invisible” to the authorities, to the public health services, and in general to the public opinion. Furthermore, when they arrive at a destination, or during their journey through Europe, many children often vanish. The full dimension of such phenomenon that further hits the unaccompanied minors along their European migration routes currently is unknown. However, the intense migration that has affected the south Mediterranean borders of the EU over the last 10 years has allowed the collection of sufficient data to raise the high…
The standing knee lift test is not a useful screening tool for time loss from low back pain in youth basketball and floorball players
2021
Abstract Objectives The aim of this study was to investigate the association between pelvic kinematics during the standing knee lift (SKL) test and low back pain (LBP) in youth floorball and basketball players. Design A prospective cohort study. Setting Finnish elite youth floorball and basketball players. Participants Finnish elite youth female and male floorball and basketball players (n = 258, mean age 15.7 ± 1.8). Main outcome measures LBP resulting in time loss from practice and games was recorded over a 12-month period and verified by a study physician. Associations between LBP and sagittal plane pelvic tilt and frontal plane pelvic obliquity during the SKL test as measured at baselin…
Uric acid is linked to cardiometabolic risk factors in overweight and obese youths.
2018
OBJECTIVE Observational studies have indicated that high levels of serum uric acid are associated with the risk of cardiovascular disease. The aim of the present study is to investigate the association of uric acid with individual cardiometabolic risk factors, as well as their degree of clustering, in overweight and moderate obese youth. METHODS Three hundred and thirty-three Caucasians of both sexes (149 women), from 5-18 years of age from those who underwent an assessment of overweight/obesity. Anthropometric parameters, office and 24-h blood pressure measurements and metabolic profile, including HDL-cholesterol, triglycerides, insulin, HOMA index and uric acid were assessed. RESULTS Uric…
Fun, influence and competence—a mixed methods study of prerequisites for high school students’ participation in physical education
2016
Background: Many adolescents do not reach the recommended levels of physical activity (PA), and students attending vocational studies are less committed to take part in physical education (PE) than other students. The purpose of the present study was twofold: 1) to examine differences in physical activity, diet, smoking habits, sleep and screen time among Norwegian vocational high school students who selected either a PE model focusing on PA skills, technique and improvement of physical performance (“Sports enjoyment”) or more on health, play and having fun when participating in PE lessons (“Motion enjoyment”), and 2) to explore the students’ experiences with PE programs. Methods: In this m…
Motivation for physical activity in adolescents with asthma
2020
Objective: We explored motivation for physical activity (PA) and exercise in adolescents with asthma who entered and continued a 10-week play-based exercise intervention. Methods: Eighteen adolescents with asthma, aged 13–17 years, participated in a 10-week play- and interval-based indoor exercise intervention during winter and autumn months. Semi-structured focus group interviews were conducted in weeks 2 and 8, focusing on motivation for PA and exercise, as well as field observations of exercise sessions in weeks 2, 6, and 8. The first interview was analyzed separately from the second one and descriptive observational data were obtained using thematic analysis and self-determination theor…
Positive Adolescent Development: Effects of a Psychosocial Intervention Program in a Rural Setting
2020
The Positive Youth Development (PYD) approach identifies adolescents as resources to be empowered rather than problems to be solved. All adolescents have strengths and will fully develop when these strengths are integrated with healthy resources in the diverse environments where they live and interact. The objective of this study was twofold: (1) to present the Positive Development Program for Adolescents living in rural areas (DPAR Program) and (2) to pilot test the intervention program. The DPAR program was evaluated using a repeated-measures design before and after the intervention, with an intervention group and a control group. The sample consisted of 176 adolescents between 11 and 15 …
Different neighborhood walkability indexes for active commuting to school are necessary for urban and rural children and adolescents

Sympathetic neural activity, metabolic parameters and cardiorespiratory fitness in obese youths.
2017
OBJECTIVE: The main objective of this cross-sectional study is to assess the cardiac autonomic neural activity in the presence of abnormally increased body weight in youths and its relationship to metabolic risk factors and cardiorespiratory fitness (CRF). METHODS: Sixty-four overweight and obese patients, aged 9-17 years, of both sexes, stratified according to the international BMI cut-off, were enrolled. Continuous ECG was recorded during 15 min in resting conditions, and the heart rate variability (HRV) was measured in the time domain, frequency domain and for nonlinear dynamics. In addition, cardiometabolic risk factors and CRF in effort conditions were assessed. RESULTS: Among the over…
Reproducibility of pulse wave velocity and augmentation index derived from non-invasive occlusive oscillometric tonometry analysis in adolescents
2018
The aim of this study was to investigate the short-term reproducibility of aortic pulse wave velocity (PWVao) and augmentation index (AIx%) assessed by the non-invasive oscillometric device. Altogether of 55 (19 boys, 36 girls) adolescents 16-19-years-of-age participated in the study. PWVao and AIx% were measured during the same laboratory visit at 2 min intervals using the Arteriograph™ device. Peak oxygen uptake (VO2peak ) was assessed by the maximal exercise test on a cycle ergometer and body fat percentage by bioelectrical impedance analysis. We studied reproducibility using intraclass correlation coefficients (ICC), coefficient variation with the root-means-square method expressed as p…
