Trends in sleeping difficulty among adolescents in five Nordic countries 2002–2014

2019

Sleep has been found to be an important factor in adolescents’ mental and physical health. The aim of the present study was to examine trends in sleep difficulty (i.e., difficulty falling asleep more often than once a week) in the Nordic countries among 11- to 15-year-olds. We analysed Nordic data from the Health Behaviour in School-aged Children study (HBSC), which is conducted every four years, looking specifically at trends in sleep difficulty over a 12-year period from 2002 to 2014. The participants were aged 11 to 15 years. The total number of participants across these years was 113,447. A large percentage (17% to 31% in 2014) of adolescents in the Nordic countries experience sleep dif…

Dance movement therapy and falls prevention

2017

Falls are a leading cause of morbidity, healthcare use and mortality. Dance is a popular form of physical activity among older people and previous research has suggested that it may improve various health outcomes in this population, including balance, gait and muscle performance. A systematic review of the potential benefits of dance on falls and fear of falling is lacking. Thus, we conducted a systematic review considering all randomized controls trials (RCTs) investigating if dance can reduce falls and improve fear of falling in older adults. Major databases were searched from inception until 1 March 2017 and a total of 10 RCTs were identified, which included a total of 680 people (n = 3…

Nonperturbative structure of the ghost-gluon kernel

2019

The ghost-gluon scattering kernel is a special correlation function that is intimately connected with two fundamental vertices of the gauge sector of QCD: the ghost-gluon vertex, which may be obtained from it through suitable contraction, and the three-gluon vertex, whose Slavnov-Taylor identity contains that kernel as one of its main ingredients. In this work we present a detailed nonperturbative study of the five form factors comprising it, using as starting point the `one-loop dressed' approximation of the dynamical equations governing their evolution. The analysis is carried out for arbitrary Euclidean momenta, and makes extensive use of the gluon propagator and the ghost dressing funct…

A field assessment of the Simplified Falling Head technique to measure the saturated soil hydraulic conductivity

2012

Abstract The Simplified Falling Head (SFH) technique to measure field saturated soil hydraulic conductivity, Kfs, has received little testing or comparison with other techniques. Different experiments were carried out to i) determine the effect of ring size on the measured conductivity; ii) compare the SFH and Pressure Infiltrometer (PI) techniques in a clay loam soil; and iii) evaluate the approach used in the SFH methodology to estimate the α* parameter. Sampling a relatively large number of sites allowed to detect statistically significant relationships between the Kfs values obtained with rings differing in diameter (0.15 and 0.30 m, respectively). The ring size effect was substantial (…

Una ricerca interculturale in Sicilia: l'innamoramento vissuto dagli adolescenti tunisini nati a Mazara del Vallo

2011

Si presenta una ricerca avviata nell’autunno del 2009. Il problema dell’educazione affettiva degli adolescenti emerge quando avviene il primo innamoramento. Tale fenomeno mostra come sia andata fino a quel momento l’educazione dei sentimenti e lascia presupporre che cosa bisogna ancora fare per portarla a compimento. Si è voluto indagare, sia pure con uno strumento che non scava in profondità ma si accontenta della sincerità delle risposte, il modo in cui gli adolescenti tunisini nati in Sicilia vivono il fenomeno del primo innamoramento e i cambiamenti che tale fenomeno determina negli adolescenti che lo vivono e nel loro più immediato intorno sociale. Si espongono i risultati relativi agl…

Il primo innamoramento vissuto dagli adolescenti palermitani

2012

In questo contributo, è presentato il processo di una ricerca avviata nel 2010. Il problema dell'educazione affettiva degli adolescenti emerge quando si verifica il primo innamoramento. Questo fenomeno mostra come l'educazione dei sentimenti fino ad ora si è sviluppata e presuppone ciò che è necessario per completarlo. Volevamo indagare sul modo in cui gli adolescenti palermitani vivono il primo innamoramento e sui cambiamenti che questo fenomeno provoca negli adolescenti che lo vivono e nel loro ambiente sociale immediato. Si è utilizzato uno strumento (l'intervista) che non va abbastanza in profondità, ma si limita a rilevare la sincerità delle risposte. Dopo aver descritto il modo in cui…

Balance confidence and functional balance are associated with physical disability after hip fracture.

2012

Abstract Background This cross-sectional study investigated the associations between balance confidence, functional balance, and physical disability among older people after hip fracture. Material and methods The study utilizes baseline data of two randomized controlled trials (ISRCTN34271567 and ISRCTN53680197). The participants were 159 community-dwelling over 60-year-old people. Health, fracture status, the date and type of surgery, and contraindications for participation were assessed in a clinical examination. Balance confidence was assessed by the Activities-specific Balance Confidence Scale (ABC) and functional balance by the Berg Balance Scale. Physical disability was assessed by a …

Shifts in Key Time Points and Strategies for a Multisegment Motor Task in Healthy Aging Subjects

2018

International audience; In this study, we compared key temporal points in the whole body pointing movement of healthy aging and young subjects. During this movement, subject leans forward from a standing position to reach a target. As it involves forward inclination of the trunk, the movement creates a risk for falling. We examined two strategic time points during the task-first, the crossover point where the velocity of the center of mass (CoM) in the vertical dimension outstripped the velocity in the anteroposterior dimension and secondly, the time to peak of the CoM velocity profile. Transitions to stabilizing postures occur at these time points. They both occurred earlier in aging subje…

Square-stepping exercise versus strength and balance training for fall risk factors

2008

Background and aims: Feasible and low-cost exercise programmes targeting fall risk factors may decrease the risk of falling in older adults. The purpose of this study was to compare the effects of square-stepping exercise (SSE) training, which is a new and low-cost method designed to improve lower-extremity functional fitness, with strength and balance (SB) training. Methods: The study included 39 community-dwelling adults aged 65 to 74 years. The participants were randomized to either group SSE (n=20) or SB (n=19). They engaged in 70-min group exercise sessions twice a week for 12 weeks. The efficacy of the program was measured with both a 9-item test battery for assessment of physical per…
