Technical developments have made it possible to analyze very low amounts of DNA. This has many advantages, but the drawback of this technological progress is that interpretation of the results becomes increasingly complex: the number of mixed DNA profiles increased relatively to single source DNA profiles and stochastic effects in the DNA profile, such as drop-in and drop-out, are more frequently observed. Moreover, the relevance of low template DNA material regarding the activities alleged is not as straightforward as it was a few years ago, when for example large quantities of blood were recovered. The possibility of secondary and tertiary transfer is now becoming an issue. The purpose of this research is twofold: first, to study the transfer of DNA from the handler and secondly, to observe if handlers would transfer DNA from persons closely connected to them. We chose to mimic cases where the offender would attack a person with a knife. As a first approach, we envisaged that the defense would not give an alternative explanation for the origin of the DNA. In our transfer experiments (4 donors, 16 experiments each, 64 traces), 3% of the traces were single DNA profiles. Most of the time, the DNA profile of the person handling the knife was present as the major profile: in 83% of the traces the major contributor profile corresponded to the stabber's DNA profile (in single stains and mixtures). Mixture with no clear major/minor fraction (12%) were observed. 5% of the traces were considered of insufficient quality (more than 3 contributors, presence of a few minor peaks). In that case, we considered that the stabber's DNA was absent. In our experiments, no traces allowed excluding the stabber, however it must be noted that precautions were taken to minimize background DNA as knives were cleaned before the experiments. DNA profiles of the stabber's colleagues were not observed. We hope that this study will allow for a better understanding of the transfer mechanism and of how to assess and describe results given activity level propositions. In this preliminary research, we have focused on the transfer of DNA on the hand of the person. Besides, more research is needed to assign the probability of the results given an alternative activity proposed by the defense, for instance when the source of the DNA is not contested, but that the activities are.

Partint de la base teòrica de la proxèmica i l’espai personal, l’objectiu d’aquest treball era investigar la influència que té el sexe de l’individu i el de la persona amb la qual s’interactua en referència a la distància interpersonal. Així mateix, es pretenia esbrinar si hi ha una connexió entre el sexe i la conducta compensatòria que es realitzarà quan l’espai personal és envaït. L’estudi s’ha realitzat amb 60 joves de la Universitat de Barcelona, estudiants entre 1r i 4t de Grau en diversos estudis socials mitjançant un experiment de camp. Els resultats mostren que ambdues variables tenen una influència significativa en la regulació de l’espai personal d’un individu.

BackgroundWe herein evaluate the Spanish population¿s trends in health burden by comparing results of two Global Burden of Diseases, Injuries, and Risk Factors Studies (the GBD studies) performed 20 years apart.MethodsData is part of the GBD study for 1990 and 2010. We present results for mortality, years of life lost (YLLs), years lived with disability, and disability-adjusted life years (DALYs) for the Spanish population. Uncertainty intervals for all measures have been estimated.ResultsNon-communicable diseases accounted for 3,703,400 (95% CI 3,648,270¿3,766,720) (91.3%) of 4,057,400 total deaths, in the Spanish population. Cardiovascular and circulatory diseases were the main cause of mortality among non-communicable diseases (34.7% of total deaths), followed by neoplasms (27.1% of total deaths). Neoplasms, cardiovascular and circulatory diseases, and chronic respiratory diseases were the top three leading causes for YLLs. The most important causes of DALYs in 2010 were neoplasms, cardiovascular and circulatory diseases, musculoskeletal disorders, and mental and behavioral disorders.ConclusionsMortality and disability in Spain have become even more linked to non-communicable diseases over the last years, following the worldwide trends. Cardiovascular and circulatory diseases, neoplasms, mental and behavioral disorders, and neurological disorders are the leading causes of mortality and disability. Specific focus is needed from health care providers and policy makers to develop health promotion and health education programs directed towards non-communicable disorders.

The increasing incidence of type 1 diabetes has led researchers on a quest to find the reason behind this phenomenon. The rate of increase is too great to be caused simply by changes in the genetic component, and many environmental factors are under investigation for their possible contribution. These studies require, however, the participation of those individuals most likely to develop the disease, and the approach chosen by many is to screen vast populations to find persons with increased genetic risk factors. The participating individuals are then followed for signs of disease development, and their exposure to suspected environmental factors is studied. The main purpose of this study was to find a suitable tool for easy and inexpensive screening of certain genetic risk markers for type 1 diabetes. The method should be applicable to using whole blood dried on sample collection cards as sample material, since the shipping and storage of samples in this format is preferred. However, the screening of vast sample libraries of extracted genomic DNA should also be possible, if such a need should arise, for example, when studying the effect of newly discovered genetic risk markers. The method developed in this study is based on homogeneous assay chemistry and an asymmetrical polymerase chain reaction (PCR). The generated singlestranded PCR product is probed by lanthanide-labelled, LNA (locked nucleic acid)-spiked, short oligonucleotides with exact complementary sequences. In the case of a perfect match, the probe is hybridised to the product. However, if even a single nucleotide difference occurs, the probe is bound instead of the PCR product to a complementary quencher-oligonucleotide labelled with a dabcyl-moiety, causing the signal of the lanthanide label to be quenched. The method was applied to the screening of the well-known type 1 diabetes risk alleles of the HLA-DQB1 gene. The method was shown to be suitable as an initial screening step including thousands of samples in the scheme used in the TEDDY (The Environmental Determinants of Diabetes in the Young) study to identify those individuals at increased genetic risk. The method was further developed into dry-reagent form to allow an even simpler approach to screening. The reagents needed in the assay were in dry format in the reaction vessel, and performing the assay required only the addition of the sample and, if necessary, water to rehydrate the reagents. This allows the assay to be successfully executed even by a person with minimal laboratory experience.

Implementation of different policies and plans aiming at providing education for all is a challenge in Tanzania. The need for educators and professionals with relevant knowledge and qualifications in special education is substantial. Teacher education does not equip educators with sufficient knowledge and skills in special education and professional development programs in special education are few in number. Up to 2005 no degree programs in special education at university level were available in Tanzania. The B.Ed. Special Education program offered by the Open University of Tanzania in collaboration with Åbo Akademi University in Finland was one of the efforts aimed at addressing the big national need for teachers and other professionals with degree qualifications in special education. This pilot program offered unique possibilities to study professional development in Tanzania. The research group in this study consisted of the group of students who participated in the degree program 2005-2007. The study is guided by three theoretical perspectives: individual, social and societal. The individual perspective emphasizes psychological factors as motives, motivation, achievement, self-directed behavior and personal growth. Within social perspective, professional development is viewed as situated within the social and cultural context. The third perspective, the societal, focuses on change, reforms, innovations and transformation of school systems and societies. Accordingly, professional development is viewed as an individual, social and societal phenomenon. The overall aim of the study is to explore the participants’ motives for participating in a B.Ed. Special Education program and the perceived outcomes of the program in terms of professional development. In order to achieve the objectives of the study, a case study approach was adopted. Questionnaires and semi-structured interviews were administered in three waves between January 2007 and February 2009 to the 35 educators participating in the B.Ed. Special Education program. The findings of the study reveal that the participants expressed motives which were related to job performance, knowledge, skills, academic degree and career. Also altruistic motives were expressed by the participants in terms of helping and supporting students with special needs and their communities. The perceived outcomes of the program were in line with the expressed motives. However, the results indicate that the participants also learned new skills, as interaction skills and guidance and counseling skills. Increased self-confidence was also mentioned as an outcome. The participants also got deepened understanding of disability issues. In addition, they learned strategies for creating awareness of persons with disability in the communities. Thus the findings of the study indicate positive outcomes of the program in terms of professional development. The conclusion of the study is that individual, social and societal factors interact when it comes to explaining why Tanzanian educators in special education choose to pursue a degree program in special education. The individual motives, as increased knowledge and better prospects of career development interact with the social and societal motives to help and support vulnerable student groups. The study contributes to increased understanding of the complexity of professional development and of the realities educators meet when educational reforms are implemented in a developing country.

Often the empirical studies about sport sponsorship co-operation have concentrated on the relationships between the sponsor and the sponsored target excluding the phenomenon sports manager, i.e. the intermediating actor from further examination. In this study the purpose was to contribute to the research gap in the current literature by thoroughly describing the roles and relationships in the sport sponsorship co-operation that includes an intermediating actor, that is a triad. The main objective was pursued to fulfill with the help of two sub-level research questions that were identified as ”What is the nature of the sport sponsorship triad?” and ”What is the role of the intermediating actor within the sport sponsorship triad?” First, the theorethical framework was constructed based on the existing literature of business relationship triads and sponsorship co-operation that were integrated in the synthesis of the theories the purpose of which was to produce a framework for empirical research. Then a qualitative research was conducted by using a single-case study approach. The data was collected through a semi-structured theme interview in person with the sports manager. Similar questionnaires were sent out to the sponsor and the athlete and answered in writing. After collecting the data, the actor roles’ and their relationships were examined individually, after which the analysis of the results was carried out and divided according to the research questions. The nature of the sport sponsorship triad was found to be a serial triad that could be likened to a system of two dyads connected by the intermediating actor. Each actor seemed to occupy a specific justifiable position within the co-operation, even though the relationships were found to be unbalanced in terms of resources, power/strength, interaction patterns and interconnectedness. The core role of the intermediating actor was found to be the role of a mediator, which was seen to increase the other parties’ dependence of the manager’s performance. Therefore, the role of the intermediating actor should be considered crucial for the very existence of the sport sponsorship co-operation, especially in cases where the nature of the triad is a serial triad.

Digitalization and technology megatrends such as Cloud services have provided SMEs with a suitable atmosphere and conditions to internationalize and seek for further business growth. There is a limited amount of research on Cloud services from the business perspective and the limitations and challenges SMEs encounter when pursuing international business growth. Thus, the main research question of this study was how Cloud services may enable Finnish SMEs to overcome international growth challenges. The research question was further divided into three sub-questions dealing with matters related to features and characteristics of Cloud services, limitations and challenges Finnish SMEs experience when pursuing international growth of business, and benefits and advantages of utilizing Cloud services to mitigate and suppress international growth challenges. First, the theoretical framework of this study was constructed based on the existing literature on Cloud services, SMEs, and international growth challenges. After this, qualitative research approach and methodology were applied for this study. The data was collected through six semi-structured expert interviews in person with representatives of IBM, Exidio, Big Data Solutions, and Comptel. After analyzing the collected data by applying thematic analysis method, the results were compared with the existing theory and the original framework was modified and complemented accordingly. Resource scarcity, customer base expansion and retention, and lack of courage to try new things and take risks turned out to be major international growth challenges of Finnish SMEs. Due to a number of benefits and advantages of utilizing Cloud services including service automation, consumption-based pricing model, lack of capital expenditures (capex) and huge upfront investments, lightened organization structure, cost savings, speed, accessibility, scalability, agility, geographical expansion potential, global reaching and covering, credibility, partners, enhanced CRM, freedom, and flexibility, it can be concluded that Cloud services can help directly and indirectly Finnish SMEs to mitigate and overcome international growth challenges and enable further business growth.

It is well documented that the majority of Tuberculosis (TB) cases diagnosed in Canada are related to foreign-bom persons from TB high-burden countries. The Canadian seasonal agricultural workers program (SAWP) operating with Mexico allows migrant workers to enter the country with a temporary work permit for up to 8 months. Preiimnigration screening of these workers by both clinical examination and chest X-ray (CXR) reduces the risk of introducing cases of active pulmonary TB to Canada, but screening for latent TB (LTBI) is not routinely done. Studies carried out in industrialized nations with high immigration from TBendemic countries provide data of lifetime LTBI reactivation of around 10% but little is known about reactivation rates within TB-endemic countries where new infections (or reinfections) may be impossible to distinguish from reactivation. Migrant populations like the SAWP workers who spend considerable amounts of time in both Canada and TBendemic rural areas in Mexico are a unique population in terms of TB epidemiology. However, to our knowledge no studies have been undertaken to explore either the existence of LTBI among Mexican workers, the probability of reactivation or the workers' exposure to TB cases while back in their communities before returning the following season. Being aware of their LTBI status may help workers to exercise healthy behaviours to avoid TB reactivation and therefore continue to access the SAWP. In order to assess the prevalence of LTBI and associated risk factors among Mexican migrant workers a preliminary cross sectional study was designed to involve a convenience sample of the Niagara Region's Mexican workers in 2007. Research ethics clearance was granted by Brock University. Individual questionnaires were administered to collect socio-demographic and TB-related epidemiological data as well as TB knowledge and awareness levels. Cellular immunity to M tuberculosis was assessed by both an Interferon-y release assay (lGRA), QuantiFERON -TB Gold In-Tube (QFf™) and by the tuberculin skin test (TSn using Mantoux. A total of 82 Mexican workers (out of 125 invited) completed the study. Most participants were male (80%) and their age ranged from 22 to 65 years (mean 38.5). The prevalence of LTBI was 34% using TST and 18% using QFTTM. As previously reported, TST (using ~lOmm cut-off) showed a sensitivity of 93.3% and a specificity of 79.1 %. These findings at the moment cannot predict the probability of progression to active TB; only longitudinal cohort studies of this population can ascertain this outcome. However, based on recent publications, lORA positive individuals may have up to 14% probability of reactivation within the next two years. Although according to the SA WP guidelines, all workers undergo TB screening before entering or re-entering Canada, CXR examination requirements showed to be inconsistent for this population: whereas 100% of the workers coming to Canada for the first time reported having the procedure done, only 31 % of returning participants reported having had a CXR in the past year. None of the participants reported ever having a CXR compatible with TB which was consistent with the fact that none had ever been diagnosed with active pulmonary TB and with only 3.6% reporting close contact with a person with active TB in their lifetime. Although Mexico reports that 99% of popUlation is fully immunized against TB within the first year of age, only 85.3% of participants reported receiving BOC vaccine in childhood. Conversely, even when TST is not part of the routine TB screening in endemic countries, a suqDrisingly high 25.6% reported receiving a TST in the past. In regards to TB knowledge and awareness, 74% of the studied population had previous knowledge about (active) TB, 42% correctly identified active TB symptomatology, 4.8% identified the correct route of transmission, 4.8% knew about the existence of LTBI, 3.6% knew that latent TB could reactivate and 48% recognized TB as treatable and curable. Of all variables explored as potential risk factors for LTBI, age was the only one which showed statistical significance. Significant associations could not be proven for other known variables (such as sex, TB contact, history of TB) probably because of the small sample size and the homogeneity of the sample. Screening for LTBI by TST (high sensitivity) followed by confirmation with QFT''"'^ (high specificity) suggests to be a good strategy especially for immigrants from TB high-burden countries. After educational sessions, workers positive for LTBI gained greater knowledge about the signs and symptoms of TB reactivation as well as the risk factors commonly associated with reactivation. Additionally, they were more likely to attend their annual health check up and request a CXR exam to monitor for TB reactivation.

The purpose of this study was to examine the influence of family support on diabetes education behavioural outcomes, specifically in relation to diet, exercise, and blood glucose monitoring in adult individuals with Type 2 diabetes. Fifty-three individuals attending diabetes education for the first time were followed approximately 1 month. The findings for the influence of family support were mixed. Family attending diabetes class with participants had a positive influence with respect to diet. This is consistent with Carl Rogers (1969) who espouses setting a positive climate for learning and that learning new attitudes or information comes when external barriers are at a minimum. However family attending class with participants had no influence with respect to exercise or blood glucose monitoring. The family support action of encouraging with respect to diet overall did not influence healthy eating behaviours except for decreased skipped meals and scheduled snacks. In fact, in the areas of family willing to make healthy choices along with participant, the less the family was involved in encouraging, the better the participant did. Exercise on the other hand was influenced positively by family encouragement. This is consistent with Bandura's theory that enhancement of self-confidence and self-efficacy can lead to desired behaviour changes. Family encouragement however did not appear to influence blood glucose monitoring behaviours. This study has implications for practice in that diabetes education programs can encourage family to attend classes or get involved in encouraging the person with diabetes, so that it may help to increase healthy eating behaviours and exercise. As time is necessary to implement changes in behaviour, future research can look at the influence of family support over a 6-month, I-year, or greater period.

Chez les personnes âgées, la dépression est un problème important en santé publique, à cause de sa prévalence élevée et de son association avec les incapacités fonctionnelles, la mortalité et l’utilisation des services. La plupart des études ont montré que le manque de relations sociales était associé à la dépression, mais les résultats ne sont pas clairs. Au Québec et au Canada, on possède peu de données sur la prévalence de la dépression chez les personnes âgées et de son association avec les relations sociales. Peu d’études ont examiné le rôle des relations sociales sur l’utilisation des services de santé par les personnes âgées déprimées. Le but de cette recherche était d’examiner le rôle des relations sociales dans la présence de la dépression et dans la consultation chez un professionnel de la santé des personnes âgées déprimées, au Québec. Plus spécifiquement, ce travail visait à : 1) examiner les associations entre les relations sociales et les troubles dépressifs selon la région de résidence; 2) examiner les associations différentielles des relations sociales sur la dépression des femmes et des hommes âgés; 3) examiner le rôle des relations sociales dans la consultation auprès d’un professionnel de la santé des personnes âgées déprimées. Pour répondre à ces objectifs, nous avons utilisé les données de l’enquête ESA (Enquête sur la Santé des Aînés), réalisée en 2005 -2006 auprès d’un échantillon de 2670 personnes âgées résidant à domicile au Québec, qui nous ont permis de rédiger trois articles. Les troubles dépressifs (incluant la dépression majeure et mineure) ont été mesurés, selon les critères du DSM-IV, en excluant le critère de l’altération du fonctionnement social, professionnel ou dans d’autres domaines importants, à l’aide du questionnaire ESA développé par l’équipe de recherche. Les relations sociales ont été mesurées à l’aide de cinq variables : (1) le réseau social; (2) l’intégration sociale; (3) le soutien social, (4) la perception d’utilité auprès des proches et (5) la présence de relations conflictuelles avec le conjoint, les enfants, les frères et sœurs et les amis. Des modèles de régression logistique multiple ont été ajustés aux données pour estimer les rapports de cote et leur intervalle de confiance à 95 %. Nos résultats ont montré des prévalences de dépression plus élevées chez les personnes qui résident dans les régions rurales et urbaines, comparées à celles qui résident dans la région métropolitaine de Montréal. La pratique du bénévolat, le soutien social et les relations non conflictuelles avec le conjoint sont associés à une faible prévalence de dépression, indépendamment du type de résidence. Comparés aux hommes, les femmes ont une prévalence de dépression plus élevée. L’absence de confident est associée à une prévalence de dépression élevée, tant chez les hommes que chez les femmes. La probabilité de dépression est plus élevée chez les hommes veufs et chez ceux qui ne pratiquent pas d’activités de bénévolat, comparativement à ceux qui sont mariés et font du bénévolat. Chez les femmes, aucune association significative n’a été observée entre le statut marital, le bénévolat et la dépression. Cependant, la présence de relations conflictuelles avec le conjoint est associée avec la dépression, seulement chez les femmes. Les relations avec les enfants, les frères et sœurs et les amis ne sont pas associées avec la dépression dans cette population de personnes âgées du Quebec. En ce qui concerne la consultation chez un professionnel de la santé, nos résultats ont révélé que presque la moitié des personnes âgées dépressives n’ont pas consulté un professionnel de la santé, pour leurs symptômes de dépression, au cours des 12 derniers mois. Par ailleurs, notre étude a montré que les personnes âgées qui disposent de tous les types de soutien (confident, émotionnel et instrumental) consultent plus pour leurs symptômes de dépression que ceux qui ont moins de soutien. Comparativement aux hommes mariés, les femmes mariées consultent plus les professionnels de la santé, ce qui laisse supposer que le réseau de proches (épouse et enfants) semble agir comme un substitut en réduisant la fréquence de consultation chez les hommes. Vu la rareté des études canadiennes sur la prévalence de la dépression chez les personnes âgées et les facteurs psychosociaux qui y sont associés, les résultats de ce travail seront utiles pour les cliniciens et pour les responsables des politiques à l’échelle nationale, provinciale et locale. Ils pourront guider des interventions spécifiques, selon la région de résidence et pour les hommes et les femmes âgées, dans le domaine de la santé mentale.

Le vieillissement de la population canadienne qui est appréhendé dans les années à venir entrainera son lot de défis pour l’administration des soins et services de longue durée. Par contre, une amélioration de l’état de santé fonctionnelle de la population pourrait atténuer le rythme de croissance du nombre d’aînés en état d’incapacité. Utilisant les données transversales de l’Enquête nationale sur la santé de la population (ENSP) et de l’Enquête de santé dans les collectivités canadiennes (ESCC), cette recherche analyse les tendances dans les niveaux d’incapacité chez les personnes de 65 ans et plus vivant dans les ménages privés au Canada entre 1994 et 2005, ainsi que les caractéristiques sociodémographiques associées au risque d’être en incapacité. Les résultats montrent que la prévalence de l’incapacité est à la baisse durant la période, et que parmi les personnes en incapacité, la proportion présentant une incapacité légère a diminué. Tout étant égal par ailleurs, certaines caractéristiques sociodémographiques augmentent le risque pour une personne âgée d’être en incapacité, notamment l’âge, être une femme, la faible scolarité, et être veuf, séparé ou divorcé. Cependant, les limites relativement importantes quant à la qualité des données font en sorte que nous devons interpréter ces résultats avec prudence.

Plusieurs travaux suggèrent que les personnes atteintes d’une maladie mentale grave représentent un risque plus élevé de passage à l’acte violent que les personnes de la population en générale. Les raisons pour lesquelles ces personnes seraient plus enclines à commettre des gestes violents restent toutefois souvent contradictoires. En 1994, Link et Stueve suggéraient qu’une personne atteinte de symptômes de type menace/atteintes aux mécanismes de contrôle (TCO), était significativement plus à risque de commettre un geste violent. Les résultats de ces travaux furent par la suite reproduits dans le cadre d’autres études. L’objectif de ce rapport de stage est de mieux comprendre la relation entre les symptômes TCO et le passage à l’acte agressif en cours d’hospitalisation. Pour ce faire, les informations concernant la symptomatologie et les passages à l’acte violents de deux résidents de l’Institut Philippe-Pinel de Montréal (IPPM) sont présentées sous forme d’études de cas. L’analyse du contenu clinique des études de cas suggère qu’une approche nomothétique ne permet de comprendre qu’en partie l’association entre le passage à l’acte agressif et les symptômes TCO. Une telle approche ne permet pas d’intégrer d’autres facteurs cliniques tels les hallucinations ou les idées de violence, à l’étude du passage à l’acte agressif. Une approche phénoménologique où l’on s’intéresse à la compréhension qu’a la personne de son environnement et aux moyens qu’elle envisage afin d’y répondre semble offrir davantage de pistes afin de comprendre le passage à l’acte violent chez la personne atteinte d’une maladie mentale grave.

Cette thèse a pour objectif de déterminer quelques aspects des figurations du sujet au XVIIe siècle à travers une lecture conjointe des romans à la première personne et des textes philosophiques de cette période. Partant de questionnements proches, ces deux genres discursifs construisent une figure du sujet savant et itinérant : être animé d'un désir de connaissance et amené à repenser les conditions d'énonciation de son expérience particulière. Pour les auteurs du corpus, la vérité se découvre au fil d'expériences singulières si bien que dire le monde avec exactitude revient à l'énoncer à la première personne, à en rendre une perception d'abord subjective. Se pose alors le problème de la légitimation de l'énonciation personnelle, légitimation qui permet d'articuler la première personne à une altérité tout en conservant la singularité du sujet. Cette singularité se double toujours d'une dispersion des identités du sujet et des référents de la première personne. Mais narration, fiction et usages du corps figurent cette identité en constellation. Les deux premières exposent la diversité des visages du « je », leurs concordances ou leurs discordances, à la fois être passé et présent, homme réel et personnage imaginaire, narrateur et auteur. Dans les usages liés aux peines et aux plaisirs du corps se dessine une autre forme de rencontre possible entre la particularité du sujet et l'autre : celui qu'il désire, avec lequel il souffre, avec lequel il jouit, qui vit en lui. Par tous ces aspects, énonciatif, narratif, fictionnel, physique, la subjectivité construite par les textes est toujours et essentiellement une relation : récit raconté pour rejoindre autrui.

Objectifs : Cette thèse porte sur l’association entre les caractéristiques socioenvironnementales des voisinages (milieux locaux) et la prévalence des limitations d’activités (ou handicap) dans la population québécoise. Elle a trois objectifs principaux : (1) clarifier les enjeux conceptuels et méthodologiques relatifs à l’étude des déterminants socioenvironnementaux des limitations d’activités; (2) décrire les contributions respectives de la composition socioéconomique des voisinages et de facteurs contextuels à la variabilité locale de la prévalence des limitations d’activités; (3) évaluer la présence d’interactions entre la santé fonctionnelle des personnes (incapacité) et des caractéristiques des voisinages en lien avec la prévalence des limitations d’activités. Méthodes : Une analyse de la littérature scientifique a été effectuée en lien avec le premier objectif de la thèse. En lien avec le deuxième objectif, des données pour le Québec du recensement canadien de 2001 (échantillon de 20% de la population) ont été utilisées pour estimer l’association entre la prévalence des limitations d’activités et des caractéristiques des voisinages : classification urbain-rural, composition socioéconomique (défavorisation matérielle et sociale) et facteurs contextuels (qualité des habitations, stabilité résidentielle et utilisation des transports actifs et collectifs). En lien avec le troisième objectif, des données pour la population urbaine du Québec issues de l’Enquête sur la santé dans les collectivités canadiennes (2003, 2005 et 2007/2008) ont permis de tester la présence d’interaction entre la santé fonctionnelle des personnes et des caractéristiques des voisinages (défavorisation matérielle et sociale, qualité des habitations, stabilité résidentielle et densité des services). Pour les analyses associées aux deux derniers objectifs, l’analyse des corrélats de la prévalence des limitations d’activités a été effectuée à l’aide de régressions logistiques multiniveaux. Résultats : Différents éléments conceptuels et opérationnels limitent la possibilité de faire une synthèse des analyses épidémiologiques portant sur les influences socioenvironnementales sur les limitations d’activités. Les résultats des analyses empiriques suggèrent que : (1) la variation géographique de la prévalence des limitations d’activités s’explique en grande partie par la composition socioéconomique des voisinages; (2) des facteurs contextuels sont associés à cette variation géographique; (3) les mesures relatives d’inégalités sous-estiment les disparités contextuelles dans la distribution des nombres absolus de personnes ayant une limitation d’activités; et (4) l’association entre la prévalence des limitations d’activités et la défavorisation sociale pourrait varier selon la santé fonctionnelle des personnes. Conclusions : Différentes caractéristiques socioenvironnementales sont potentiellement associées aux variations géographiques des limitations d’activités au Québec. Le développement d’indicateurs socioenvironnementaux favoriserait une connaissance plus précise de l’influence de ces caractéristiques socioenvironnementales sur les limitations d’activités et des mécanismes par lesquels s’exerce cette influence. L’établissement d’un système national de surveillance des aménagements territoriaux est proposé afin de soutenir la recherche et la prise de décision. Des indicateurs locaux d’accessibilité aux transports, aux espaces publics ainsi qu’aux services de proximité devraient être priorisés. Ces aspects de l’aménagement du territoire sont susceptibles de rejoindre plusieurs enjeux de santé publique et ils ont comme autre avantage d’être inclus dans différentes orientations québécoises ciblant le vieillissement en santé et la réduction des limitations d’activités.
