Promoting state health department evidence-based cancer and chronic disease prevention: A multi-phase dissemination study with a cluster randomized trial component
BACKGROUND: Cancer and other chronic diseases reduce quality and length of life and productivity, and represent a significant financial burden to society. Evidence-based public health approaches to prevent cancer and other chronic diseases have been identified in recent decades and have the potential for high impact. Yet, barriers to implement prevention approaches persist as a result of multiple factors including lack of organizational support, limited resources, competing emerging priorities and crises, and limited skill among the public health workforce. The purpose of this study is to learn how best to promote the adoption of evidence based public health practice related to chronic disease prevention. METHODS/DESIGN: This paper describes the methods for a multi-phase dissemination study with a cluster randomized trial component that will evaluate the dissemination of public health knowledge about evidence-based prevention of cancer and other chronic diseases. Phase one involves development of measures of practitioner views on and organizational supports for evidence-based public health and data collection using a national online survey involving state health department chronic disease practitioners. In phase two, a cluster randomized trial design will be conducted to test receptivity and usefulness of dissemination strategies directed toward state health department chronic disease practitioners to enhance capacity and organizational support for evidence-based chronic disease prevention. Twelve state health department chronic disease units will be randomly selected and assigned to intervention or control. State health department staff and the university-based study team will jointly identify, refine, and select dissemination strategies within intervention units. Intervention (dissemination) strategies may include multi-day in-person training workshops, electronic information exchange modalities, and remote technical assistance. Evaluation methods include pre-post surveys, structured qualitative phone interviews, and abstraction of state-level chronic disease prevention program plans and progress reports.

Do associations of sex, age and education with transport and leisure-time physical activity differ across 17 cities in 12 countries?
Background: Leisure-time and transport activity domains are studied most often because they are considered
more amenable to intervention, but to date evidence on these domains is limited. The aim of the present study
was to examine patterns of socio-demographic correlates of adults’ leisure-time and transport physical activity and
how these associations varied across 17 cities in 12 countries.
Methods: Participants (N = 13,745) aged 18–66 years in the IPEN Adult study and with complete data on sociodemographic and self-reported physical activity characteristics were included. Participants reported frequency and
duration of leisure-time and transport activities in the last 7 days using the self-administered International Physical
Activity Questionnaire-Long Form. Six physical activity outcomes were examined in relation with age, education,
and sex, and analyses explored variations by city and curvilinear associations.
Results: Sex had the most consistent results, with five of six physical activity outcomes showing females were less
active than males. Age had the most complex associations with self-report transport and leisure-time physical
activity. Compared to older people, younger adults were less likely to engage in transport physical activity, but
among those who did, younger people were likely to engage in more active minutes. Curvilinear associations were
found between age and all three leisure-time physical activity outcomes, with the youngest and the oldest being
more active. Positive associations with education were found for leisure-time physical activity only. There were
significant interactions of city with sex and education for multiple physical activity outcomes.
Conclusions: Although socio-demographic correlates of physical activity are widely studied, the present results
provide new information. City-specific findings suggest there will be value in conducting more detailed case
studies. The curvilinear associations of age with leisure-time physical activity as well as significant interactions of
leisure-time activity with sex and education should be further investigated. The findings of lower leisure-time
physical activity among females as well as people with low education suggest that greater and continued efforts in
physical activity policies and programs tailored to these high-risk groups are needed internationally
Study protocol: healthy urban living and ageing in place (HULAP): an international, mixed methods study examining the associations between physical activity, built and social environments for older adults the UK and Brazil
Abstract Background The ability to ‘age in place’ is dependent on a range of inter-personal, social and built environment attributes, with the latter being a key area for potential intervention. There is an emerging body of evidence that indicates the type of built environment features that may best support age friendly communities, but there is a need to expand and consolidate this, while generating a better understanding of how on how research findings can be most effectively be translated in to policy and practice. Methods The study is based on two case study cities, Curtiba (Brazil) and Belfast (UK), which have highly contrasting physical, social and policy environments. The study deploys a mix methods approach, mirrored in each city. This includes the recruitment of 300 participants in each city to wear GPS and accelerometers, a survey capturing physical functioning and other personal attributes, as well as their perception of their local environment using NEWS-A. The study will also measure the built environments of the cities using GIS and develop a tool for auditing the routes used by participants around their neighbourhoods. The study seeks to comparatively map the policy actors and resources involved in healthy ageing in the two cities through interviews, focus groups and discourse analysis. Finally, the study has a significant knowledge exchange component, including the development of a tool to assess the capacities of both researchers and research users to maximise the impact of the research findings. Discussion The HULAP study has been designed and implemented by a multi-disciplinary team and integrates differing methodologies to purposefully impact on policy and practice on healthy ageing in high and low-middle income countries. It has particular strengths in its combination of objective and self-reported measures using validated tools and the integration of GPS, accelerometer and GIS data to provide a robust assessment of ‘spatial energetics’. The strong knowledge exchange strand means that the study is expected to also contribute to our understanding of how to maximise research impact in this field and create effective evidence for linking older adult’s physical activity with the social, built and policy environments
Association between private and public places and practice of physical activity in adults
There are some studies that showed the relationship between built environment with practice of physical activity during leisure-time and active transportation in the adult population. However, this relationship may be influence by type and intensity of physical activity. The aim of this study was to verify association between public and private places for engaging in different types of physical activity in adults of Rio Claro City, Brazil. Cross sectional study with representative sample of 1588 adults with a mean age of 45.7±17.0 years completed the IPAQ-long form. Geographic Information System data were employed to assess the built environment. The time to different physical activity types were divided in actives (≥10 min/week) and inactive (<10 min/week). Poisson Multilevel Regression Analysis was performed in the Stata version 12.0. After adjusting for confounders, walking during leisure-time was positively associated with São Paulo’s Social Vulnerability Index (SSVI) categories of 1 (PR=2.77) through 5 (PR=1.94) and negatively associated with population density higher than 68 km/m2 (PR=0.70). Vigorous intensity physical activity was negatively associated with distance greater than 596 metes of private places to practice physical activity (PR=0.50). Total leisure time physical activity was positively associated with SSVI 1 (PR=2.48) and 5 (RP=1.89). Moderate intensity physical activity was not associated with built environment factors. There were differents associations between the built environment factors with leisure time PA except to moderate intensity physical activity
International evaluation of the Microscale Audit of Pedestrian Streetscapes (MAPS) Global instrument : Comparative assessment between local and remote online observers
Objectives
The use of online imagery by non-local observers to conduct remote, centralized collection of streetscape audit data in international studies has the potential to enhance efficiency of collection and comparability of such data for research on built environments and health. The objectives of the study were to measure (1) the consistency in responses between local in-field observers and non-local remote online observers and (2) the reliability between in-country online observers and non-local remote online observers using the Microscale Audit of Pedestrian Streetscapes Global tool to characterize pedestrian-related features along streets in five countries.
Methods
Consistency and inter-rater reliability were analyzed between local and non-local observers on a pooled database of 200 routes in five study regions (Melbourne, Australia; Ghent, Belgium; Curitiba, Brazil; Hong Kong, China; and Valencia, Spain) for microscale environmental feature subscales and item-level variables using the intraclass correlation coefficient (ICC).
Results
A local in-field versus remote online comparison had an ICC of 0.75 (95 % CI: 0.68–0.80) for the grand total score. An ICC of 0.91 (95 % CI: 0.88–0.93) was found for the local online versus remote online comparison. Positive subscales yielded stronger results in comparison to negative subscales, except for the similarly poor-performing positive aesthetics/social characteristics.
Conclusions
This study demonstrated remote audits of microscale built environments using online imagery had good reliability with local in-field audits and excellent reliability with local online audits. Results generally supported remote online environmental audits as comparable to local online audits. This identification of low-cost and efficient data acquisition methods is important for expanding research on microscale built environments and physical activity globally
