Neighbourhood Environments and Lifestyle Behaviours in Adolescents With Type 1 Diabetes.

OBJECTIVES: Early prevention strategies are needed to mitigate the high risk of cardiovascular disease in adolescents with type 1 diabetes (T1D). Residential neighbourhood features can promote healthy lifestyle behaviours and reduce cardiovascular risk, but less is known about their role in lifestyle behaviours in adolescents with T1D, and no studies used comparisons to healthy controls. METHODS: We examined associations between residential neighbourhood features and lifestyle behaviours in adolescents with T1D and healthy controls. Data were analyzed from the CARdiovascular Disease risk factors in pEdiatric type 1 diAbetes (CARDEA) study, a cross-sectional investigation of 100 adolescents with T1D (14 to 18 years) from a pediatric diabetes clinic in Montréal, Canada, and 97 healthy controls. Outcomes included physical activity and sedentary behaviour (accelerometry), screen time and sleep duration (questionnaires), and dietary habits (24-hour recalls). Cluster analysis of selected neighbourhood indicators computed for participants' postal codes resulted in 2 neighbourhood types: central urban and peri-urban. Central urban neighbourhoods were characterized by very high population density, high active living index, numerous points of interest, higher social deprivation, higher residential mobility, and lower median household income compared with peri-urban neighbourhoods. Associations of neighbourhood type with lifestyle behaviours were estimated with multiple linear regressions and interactions by T1D status were tested. RESULTS: Living in central urban neighbourhoods was associated with greater daily minutes of moderate-to-vigourous physical activity (beta = 8.61, 95% confidence interval 1.79 to 15.44) compared with living in peri-urban neighbourhoods. No associations were observed for other lifestyle behaviours, and no statistically significant interactions were found between neighbourhood type and T1D status. CONCLUSION: Features that characterize central urban built environments appear to promote physical activity in adolescents, regardless of T1D status.

[Indice du potentiel de participation sociale des Québécois âgés : cartographie des inégalités des zones métropolitaines, urbaines et rurales].

Afin de mieux comprendre la distribution géographique des facilitateurs et des obstacles à la participation sociale des Québécois âgés, cette étude visait à documenter l'Indice du potentiel de participation sociale (IPPS) selon les zones métropolitaines, urbaines et rurales. Des analyses de données secondaires, dont l'Enquête transversale sur la santé des collectivités canadiennes, ont permis de développer et de cartographier un indice composé de facteurs environnementaux associés à la participation sociale, pondérés par une analyse factorielle. En zones métropolitaines, l'IPPS était supérieur au centre qu'en périphérie, compte tenu d'une concentration accrue d'aînés et des transports. Bien qu'atténuée, la configuration était similaire en zones urbaines. En zone rurale, un IPPS élevé était associé à une concentration d'aînés et un accès aux ressources accru, sans configuration spatiale. Pour favoriser la participation sociale, l'IPPS soutient que les transports et l'accès aux ressources doivent respectivement être améliorés en périphérie des métropoles et en zone rurale.

Mastitis pathogens and antibiotic resistance in beef cows in Switzerland.

INTRODUCTION: Mastitis in beef cows has not been studied as extensively as mastitis in dairy cows, and data from Switzerland are lacking. Various studies have shown a similar pathogen spectrum as in dairy cows, which could not be confirmed in this study. To gather initial data from Switzerland, milk samples from 297 lactating beef cows from 31 herds from the Engadin Valley in the Canton of Grisons were examined bacteriologically. At least one major or minor mastitis pathogen was recovered from at least one individual-quarter or composite sample from 33 % of all cows. The most common major mastitis pathogens were Staphylococcus aureus (8,4 % of cows), Pasteurella multocida (4,1 %), Streptococcus uberis (2 %) and Streptococcus dysgalactiae (1,7 %). Sixteen percent of the cows had at least one blind quarter, but only 32 % of these had been previously detected by the owners. In the second part of the study, milk samples from beef cows with mastitis were examined bacteriologically; the cows originated from various parts of Switzerland and had been presented for veterinary treatment. Pasteurella multocida (22 %) and Staphylococcus aureus (21 %) were the most common pathogens isolated. Antibiograms using microtitration and disk diffusion testing were generated for the Staphylococcus aureus, Pasteurella multocida and Streptococcus uberis strains from both parts of the study. Fifty-six percent of the Staphylococcus aureus strains were resistant to penicillin G. Our results showed that bacteriological examination of a milk sample aids in the diagnosis and allows specific treatment of mastitis in beef cows; this may be further improved with antibacterial susceptibility testing. Our preliminary data for the resistance patterns of mastitis pathogens in beef cows will facilitate evidence-based treatment strategies.

INTRODUCTION: Les mammites chez les vaches mères n'ont pas été étudiées de manière aussi approfondie que chez les vaches laitières et les données concernant la Suisse font défaut. Diverses études ont montré un spectre pathogène similaire à celui des vaches laitières, ce qui n'a pas pu être confirmé dans cette étude. Pour rassembler les premières données en Suisse, des échantillons de lait de 297 vaches mères provenant de 31 troupeaux de la vallée de l'Engadine dans le canton des Grisons ont été examinés bactério- logiquement. Au moins un agent pathogène majeur ou mineur de mammite a été retrouvé dans au moins un quartier ou dans un échantillon composite chez 33 % de toutes les vaches. Les agents pathogènes majeurs de mammite les plus courants étaient Staphylococcus aureus (8,4 % des vaches), Pasteurella multocida (4,1 %), Streptococcus uberis (2 %) et Streptococcus dysgalactiae (1,7 %). Seize pour cent des vaches avaient au moins un quartier sec mais cela n'avait été détectés auparavant par les propriétaires que dans seulement 32 % des cas. Dans la deuxième partie de l'étude, des échantillons de lait provenant de vaches mères atteintes de mammites ont été examinés sur le plan bactériologique; les vaches provenaient de diverses régions de Suisse et avaient été présentées pour un traitement vétérinaire. Pasteurella multocida (22 %) et Staphylococcus aureus (21 %) étaient les agents pathogènes les plus fréquemment isolés. Des antibiogrammes utilisant des tests de microtitration et de diffusion sur disque ont été générés pour les souches de Staphylococcus aureus, Pasteurella multocida et Streptococcus uberis des deux parties de l'étude. Cinquante-six pour cent des souches de Staphylococcus aureus étaient résistantes à la pénicilline G. Nos résultats montrent que l'examen bactériologique d'un échantillon de lait facilite le diagnostic et permet un traitement spécifique des mammites chez les vaches mères; ceci peut être encore amélioré par des tests de sensibilité aux antibactériens. Nos données préliminaires sur les profils de résistance des agents pathogènes de mammites chez les vaches de boucherie faciliteront les stratégies de traitement fondées sur des faits.

Dementia-Friendly Neighbourhoods in Canada: A Carer Perspective.

Based on findings from a study examining the lived experiences of dementia carers in their neighbourhoods, this article offers a vision of what dementia-friendly communities could look like from a carer perspective and in a Canadian context. Twelve carers in Ottawa and its surrounding regions were interviewed using a combination of social network maps, mobile interviews, and participant-driven photography. The findings, organized according to the categories "relationships", "places", and "everyday practices", reveal that many of the carers' choices regarding businesses, services, home location, outings, and everyday practices, are based on a desire to maintain social connections and social citizenship. The article concludes with recommendations for consideration in the planning of dementia-friendly neighbourhood initiatives.

Caractéristiques environnementales favorisant la participation sociale: une enquête auprès d'aînés québécois.

We document and compare the environmental characteristics potentially associated with social participation of older Quebecers, according to the level of rurality. A survey was carried out among older Quebecers aged 65 and over recruited by different senior groups and through social media. The Questionnaire their potential for social participation, developed from a systematic literature review, was completed by respondents. According to the 515 older participants, 71.5 years old on average, environmental characteristics linked to social participation, as well as user-friendliness of the city and neighborhood, are more favorably perceived in metropolitan and urban areas than rural areas. However, access to public transportation and the welcoming and openness of local residents are more appreciated by rural respondents. These results support the presence of inequalities in social participation according to level of rurality and offer some leads for action.

Nous avons documenté et comparé les caractéristiques environnementales potentiellement associées à la participation sociale de Québécois âgés, selon le niveau de ruralité. Une enquête a été réalisée auprès de Québécois âgés de 65 ans et plus recrutés par différents regroupements d'aînés et les réseaux sociaux. Les répondants ont rempli le Questionnaire du potentiel de participation sociale, développé à partir d'une recension systématique des écrits. Selon les 515 aînés, âgés en moyenne de 71,5 ans, les caractéristiques environnementales liées à la participation sociale, ainsi que la convivialité des villes et des quartiers, sont perçues plus favorablement dans les milieux métropolitains et urbains que dans les milieux ruraux. Toutefois, l'accès à l'autobus ainsi que l'accueil et l'ouverture des gens du quartier sont davantage appréciés par les aînés ruraux. Ces résultats témoignent de la présence d'inégalités de participation sociale selon le niveau de ruralité et permettent d'envisager de nouvelles pistes d'action.

Snow and Rain Modify Neighbourhood Walkability for Older Adults.

The literature has documented a positive relationship between walkable built environments and outdoor mobility in older adults. Yet, surprisingly absent is any consideration of how weather conditions modify the impact of neighbourhood walkability. Using archived weather data linked to survey data collected from a sample of older adults in Vancouver, Canada, we found that car-dependent neighbourhoods (featuring longer block lengths, fewer intersections, and greater distance to amenities) became inaccessible in snow. Even older adults who lived in very walkable neighbourhoods walked to 25 per cent fewer destinations in snow. It is crucial to consider the impact of weather in the relationship between neighbourhood walkability and older adult mobility.

Walking and type 2 diabetes risk using CANRISK scores among older adults.

The objective of this study was to determine the association between pedometer-assessed steps and type 2 diabetes risk using the Public Health Agency of Canada-developed 16-item Canadian Diabetes Risk Questionnaire (CANRISK) among a large population-based sample of older adults across Alberta, Canada. To achieve our study objective, adults without type 2 diabetes (N = 689) aged 55 years and older provided demographic data and CANRISK scores through computer-assisted telephone interviews between September and November 2012. Respondents also wore a step pedometer over 3 consecutive days to estimate average daily steps. Logistic regression was used to assess the association between achieving 7500 steps/day and risk of diabetes (low vs. moderate and high). Overall, 41% were male, average age was 63.4 (SD 5.5) years, body mass index was 26.7 (SD 5.0) kg/m2, and participants averaged 5671 (SD 3529) steps/day. All respondents indicated they were capable of walking for at least 10 min unassisted. CANRISK scores ranged from 13-60, with 18% in the low-risk category (<21). After adjustment, those not achieving 7500 steps/day (n = 507) were more than twice as likely to belong to the higher risk categories for type 2 diabetes compared with those walking ≥7500 steps/day (n = 182) (73.6% vs. 26.4%; odds ratio: 2.37; 95% confidence interval: 1.58 - 3.57). Among older adults without diabetes, daily steps were strongly and inversely associated with diabetes risk using the CANRISK score. Walking remains an important modifiable risk factor target for type 2 diabetes and achieving at least 7500 steps/day may be a reasonable target for older adults.
