Are Reallocations between Sedentary Behaviour and Physical Activity Associated with Better Sleep in Adults Aged 55+ Years? An Isotemporal Substitution Analysis

Physical activity has been proposed as an effective alternative treatment option for the increasing occurrence of sleep problems in older adults. Although higher physical activity levels are associated with better sleep, the association between specific physical activity intensities and sedentary behaviour (SB) with sleep remains unclear. This study examines the associations of statistically modelled time reallocations between sedentary time and different physical activity intensities with sleep outcomes using isotemporal substitution analysis. Device-measured physical activity data and both objective and subjective sleep data were collected from 439 adults aged 55+ years. Replacing 30 min of SB with moderate to vigorous intensity physical activity (MVPA) was significantly associated with an increased number of awakenings. Moreover, a reallocation of 30 min between light physical activity (LPA) and MVPA was significantly associated with increased sleep efficiency. Furthermore, reallocating 30 min of SB to LPA showed a significant association with decreased sleep efficiency. There were no significant associations of time reallocations for wake time after sleep onset, length of awakenings, and sleep quality. These results improve our understanding of the interrelationships between different intensities of movement behaviours and several aspects of sleep in older adults

An update on Inuit perceptions of their changing environment, Qikiqtaaluk (Baffin Island, Nunavut)

International audienceThe Inuit of Qikiqtaaluk (Baffin Island) have developed a deep respect for their natural environment and are able to report not only changes in weather, ice, and natural resources but also changes in their communities as a result of climate change. The objective of this study was to shed light on how the impacts of climate change are currently perceived in the communities of Kanngiqtugaapik, Pangniqtuuq, and Qikiqtarjuaq. In order to construct a shared knowledge base, we conducted qualitative video interviews and participated in a hunting camp with multigenerational and multigender Inuit hunters and fishers. First, Inuit continue to see the world in which they cohabit with other living things, particularly animals, as a world that they cannot control on their own—a world they must adapt to, passing learning from one generation to the next. Second, they report that changes in the ice have been among the major and most important transformations to have occurred in recent decades. Observations made by these local populations also indicate changes in hunted species, with fewer caribou and narwhal, more birds, insects, and fish, including from more southerly regions, and an uncertainty about polar bear populations. Seal hunting remains stable, and this meat is still the most popular and healthy food, physically and psychologically. Third, sociological and economic changes (e.g., lifestyle change, monetary economies, quotas), in addition to environmental changes (e.g., climate change, species change), have had a significant impact on food harvesting activities as well as food consumption in the region. A final perspective concerns the needs of the Qikiqtaaluk communities to further develop collaboration with scientists. This need for partnership is not only perceived as a scientific necessity but also recognized by Inuit as essential to their communities, with some local leaders ready to work toward a fruitful collaboration

Developing peer leadership among walking groups of older adults: A discussion of implementation issues related to an intervention designed in a sport context.

Walking groups constitute a promising solution for the problem of physical inactivity among older adults. These walking programs can be led by professionals, but also participants themselves can take the lead. A review concluded that peer-led walking groups are equally effective as professional-led programs. This effectiveness of peer leadership has also been studied in sports settings and qualitative peer leadership distributed over different team members seems to be an important aspect to outperform other sports teams, based on a higher goal commitment and greater confidence in the team. This insight has led to the development of shared peer leadership programs in sports teams. However, no program exists that incorporates the development of different peer leaders in walking groups. Therefore, in the present study, we investigated the effectiveness of an intervention aimed to develop peer leadership in walking groups for older adults in the context of a socio-cultural organization. Focus of the presentation is on issues concerning the context-specificity of implementing such a shared peer leadership intervention for physical activity promotion among older adults.edition: page 65status: publishe

Adaptation aux changements climatiques et à l’augmentation du niveau de la mer en zones côtières

La collection d'articles présentée dans ce hors-série est en grande partie issue du colloque « Adaptation aux changements climatiques et à l’augmentation du niveau de la mer en zones côtières : une perspective mondiale » tenu dans le cadre du 82e Congrès de l’Acfas à l'Université Concordia. L'intention du colloque était d'explorer la manière dont les communautés côtières à travers le monde s'adaptent aux problèmes causés par les changements climatiques et l'augmentation du niveau de la mer. Comment est-ce que la vulnérabilité, la résilience et la capacité d'adaptation se déclinent selon les différents contextes ? Comment est-ce que les processus sociaux se comparent d'une étude de cas à l'autre ? Comment est que les différents acteurs, dont les scientifiques, sont capables de relever les défis qui se posent aux communautés et quels sont les freins à une adaptation efficace ? Ce hors-série amène ainsi la lectrice et le lecteur dans un voyage à travers le monde, incluant Madagascar, le Vietnam, la France et l'Europe de l'Ouest, le Québec, le Nouveau-Brunswick et le monde virtuel du web

Environnement, nature et communication à l’ère de l’anthropocène

Ce dossier thématique regroupe une série de travaux qui illustrent l’effort actuel de penser en SIC (Sciences de l’information et de la communication), les façons qu’a l’environnement de venir à la communication. Ce double advenir – à la communication, mais aussi aux SIC – est placé sous le signe d’une notion, celle d’Anthropocène, qui indique une échelle quantitative et qualitative inédite de l’impact de l’humain sur la planète. Avec l’ère de l’Anthropocène, ce qui a toujours été vrai au fond (le fait que l’humain vit dans la nature, la pense, l’influence et en est influencé et formé) est devenu, pour son évidence et son ampleur liées aux effets sur le climat et le vivant, un phénomène central dans la culture et la réflexion scientifique, jusqu’à changer les catégories des sciences physiques.

It is the biannual conference of the International Organization of Physical Therapy in Mental Health (IOPTMH), and we answered with success the question: Physiotherapy in mental health; what’s next? The highly qualified scientific program, the reputable presenters, and the venue altogether form a powerful motivation for both physiotherapists and other mental health professionals to attend this conference.
