Philosophiae Doctor - PhD / The importance of health enhancing physical activity participation (HEPA) has always been emphasized globally, as one of the means to reduce the risk of Non-Communicable Diseases (NCDs) occurrence. In Africa, it is more relevant currently, due to the growing burden of NCDs that is coupled with the existing encumbrance of communicable diseases. In Rwanda, specifically, there are limited national strategies to promote health-enhancing physical activity. Consequently, the level of physical activity among Rwandans, especially government office workers, is likely to diminish, which could possibly be attributed to the rapid urbanization that comes with lifestyle changes. Basically, most people tend to abandon the traditional labour-intensive activities, which are associated with high energy expenditure, to more sedentary activities. Therefore, the need to promote health enhancing physical activity participation is crucial. Physical activity participation is an intricate and multifaceted behaviour that may not be viewed from a linear perspective. This current study adopted a socio-ecological framework to assess the factors that influence Leisure Time Physical Activity (LTPA) among government employees in Kigali City. The study used an exploratory, sequential, mixed methods of qualitative and quantitative designs, in order to comprehensively explore and understand the research problem. Qualitatively, a Case study and exploratory design was used to collect data, specifically from the Rwanda Sport Policy and its implementing stakeholders. Quantitatively, a cross-sectional, descriptive design was used to assess and describe the levels of LTPA among government workers in Kigali City, as well as highlight the various factors that influence, or limit, their participation.

En Haïti, la sécurité routière est un problème de santé publique important, causant plus de blessés et de morts que le système de santé du pays ne peut prendre en charge. Afin d’améliorer la sécurité routière, des stratégies de transfert de connaissances (TC) sont nécessaires pour promouvoir l’élaboration de politiques basées sur les connaissances issues de la recherche (CIR). Une stratégie de TC a été élaborée pour partager avec des acteurs clés les résultats de trois récentes études sur la sécurité routière en Haïti. L’objectif de la présente recherche était d’évaluer l’appréciation, le contenu et l’impact sur l’utilisation des connaissances de cette stratégie. L’étude a utilisé un devis mixte, employant deux questionnaires quantitatifs (n = 13/16) deux à trois mois après un atelier délibératif au coeur de la stratégie et des entretiens qualitatifs (n = 12/16) ont été menés sept à neuf mois post-atelier. L’atelier a généralement été apprécié par les participants, notamment pour la qualité des données présentées et pour son approche multidisciplinaire. Cependant, ils ont été déçus par l’absence de décideurs, et par le nombre et la variété limités de parties prenantes présentes. Même si les participants ont rapporté une forte volonté d’utiliser les connaissances présentées, l’atelier a eu un effet limité sur leur utilisation. Cette étude met en évidence le potentiel des ateliers délibératifs intégrés à une stratégie de TC dans les pays à revenu faible et intermédiaire, ainsi que l’importance d’inclure les décideurs dans le processus. Cette recherche aboutie à une série de recommandations pour de futurs ateliers, afin d’augmenter leur impact sur l’utilisation des connaissances et de promouvoir la prise de décision basée sur des CIR. / In Haiti, road safety is an important public health issue, causing more deaths and injuries that the country’s health system can provide for. Knowledge transfer (KT) strategies are needed to promote evidence-based policy-making (EBDM) to improve road safety. A KT strategy was developed to share with key actors the results of three recent studies about road safety in Haiti. The present research’s purpose was to evaluate the appreciation, the content, and the impact on knowledge use by key actors of this KT strategy. This research used a mixed-method design, using quantitative questionnaires (n = 13/16) two to three months following the workshop at the center of this strategy, and qualitative interviews (n = 12/16) seven to nine months post-workshop. The workshop was generally appreciated by participants, especially for the quality of the data presented and its multidisciplinary approach. However, they were disappointed by the absence of decision-makers and by the limited number and variety of stakeholders present. Even though the participants reported a strong will to do so, the workshop had limited effect on knowledge use. This study highlighted the potential of deliberative workshops as a knowledge transfer strategy in LMICs, as well as the importance to include policy-makers in the process. This research also resulted in certain recommendations for future workshops, in the objective of increasing knowledge use and of promoting evidence-based decision-making.
