RESUMO

This study explored the influence of healthy vending contracts (HVC) on the nutritional quality of vending machine products in 46 Canadian publicly funded recreation and sport facilities. A quasi-experimental comparison design was used to examine the difference in nutritional quality of snack and beverage vending machine products at baseline (December 2015-May 2016) and 18-month follow-up. Staff Surveys assessed facility contract type (HVC or conventional) and vending machine audits identified product nutritional quality. Products were categorized by provincial guidelines as Do Not Sell (DNS), Sell Sometimes (SS) or Sell Most (SM). ANOVA compared categories cross-sectionally (HVC vs conventional) and repeated measures ANOVA compared them longitudinally (HVC-HVC, vs conventional-conventional and conventional-HVC). Approximately one quarter of contracts (24% beverage and 28% snack) had health stipulations at baseline or follow-up. Cross-sectionally, facilities with HVC at any time period had significantly lower percentage DNS (beverage: 56% vs 73%, p = 0.001; snack: 55% vs 85%, p < 0.001), higher SS (beverage: 24% vs 14%, p = 0.003; snack: 35% vs 12%, p < 0.001) and higher SM Products (beverage: 21% vs 13%, p = 0.030; snack: 10% vs 3%, p < 0.003). Longitudinally, facilities with consistent HVC or that changed to HVC showed greater decreases in DNS products over time (p < 0.050). Although less healthy products were still highly prevalent, facilities with HVC or that changed to HVC had fewer unhealthy products available in their vending machines over time compared to those without HVCs. Healthy vending contracts appear to be an effective change strategy.

RESUMO

BACKGROUND: Recreation and sport facilities often have unhealthy food environments that may promote unhealthy dietary patterns among children. In response, some Canadian provinces have released voluntary nutrition guidelines for recreation and sport facilities, however implementation has been limited. Organizational capacity building may overcome barriers to implementing guidelines. Eat, Play, Live was a randomized controlled trial embedded within a natural experiment that tested the impact of an 18 month capacity building intervention (CBI) in enhancing implementation of provincial nutrition guidelines, and whether nutrition guidelines were associated with positive changes. Primary outcomes were facility capacity, policy development and food environment quality. METHODS: Recreation and sport facilities in three guideline provinces were randomized into a guideline + CBI (GL + CBI; n = 17) or a guideline only comparison condition (GL-ONLY; n = 15). Facilities in a province without guidelines constituted a second comparison condition (NO-GL; n = 17). Facility capacity, policy development, and food environment quality (vending and concession) were measured and compared at baseline and follow-up across conditions using repeated measures ANOVA and Chi-square statistics. Healthfulness of vending and concession items was rated as Do Not Sell (least nutritious), Sell Sometimes or Sell Most (most nutritious). RESULTS: There were significant time by condition effects, with significant increases in facility capacity (mean ± SD: 30.8 ± 15.6% to 62.3 ± 22.0%; p <  0.01), nutrition policy development (17.6% developed new policies; p = 0.049), overall quality of the concession food environment (14.7 ± 8.4 to 17.5 ± 7.2; p <  0.001), and in the proportion of Sell Most (3.7 ± 4.4% to 11.0 ± 9.0%; p = 0.002) and Sell Sometimes vending snacks (22.4 ± 14.4% to 43.8 ± 15.8%; p <  0.001) in GL + CBI facilities, with a significant decline in Do Not Sell vending snacks (74.0 ± 16.6% to 45.2 ± 20.1%; p <  0.001). CONCLUSIONS: Significant improvements in facility capacity, policy development and food environment quality occurred in recreation and sport facilities that were exposed to nutrition guidelines and participated in a CBI. Outcomes did not improve in facilities that were only passively or not at all exposed to guidelines. Ongoing capacity building may enhance implementation of voluntary nutrition guidelines, however food environments remained overwhelmingly unhealthy, suggesting additional scope to enhance implementation.

RESUMO

The purpose of this theoretical analysis and synthesis is to indicate how left-eye sighting dominance may lead to reading failure through dysfunctional right hemisphere letter encoding. Differing compensatory strategies are postulated to lead to outcomes that include the development of the phonologically impaired and phonologically proficient subtypes of dyslexia as well as specific spelling disability. Evidence is presented indicating that these disorders might be prevented by delaying the introduction of letter writing until the age of 8 years. Early childhood speech categorization in children genetically at-risk of developing dyslexia is also considered from this perspective. Convergent support for this premature writing hypothesis is provided by a comparison with the development of the left-hand inverted writing posture.

RESUMO

OBJECTIVE: This study investigated the effectiveness of iPad-presented social stories in increasing the on-task behaviour of three young children with autism. METHOD: A single-subject with multiple baseline across participants design was employed with three 4-year-old children to assess intervention effectiveness during structured table top activities. Observational data were digitally recorded, scored, graphed, and interpreted using 10-second interval measures over 5-min periods across baseline, intervention, and withdrawal phases. RESULTS: The combination of the social story together with the iPad proved to be an effective intervention for one of the three child participants. These findings confirm that the intervention may be effective with some children, but not others. CONCLUSION: Overall, this study builds on existing research that supports social stories as a promising practice. Further research into the use of iPad-presented social stories, particularly for children of varying ages, abilities, and learning styles is recommended.
