Self-management for obesity and cardio-metabolic fitness: Description and evaluation of the lifestyle modification program of a randomised controlled trial

Background: Sustainable lifestyle modification strategies are needed to address obesity and cardiovascular risk factors. Intensive, individualised programs have been successful, but are limited by time and resources. We have formulated a group-based lifestyle education program based upon national diet and physical activity (PA) recommendations to manage obesity and cardio-metabolic risk factors. This article describes the content and delivery of this program, with information on compliance and acceptability. Methods: Overweight/obese adults (n = 153) with metabolic syndrome were recruited from the community and randomly allocated to intervention (INT) or control (CON). Written copies of Australian national dietary and PA guidelines were provided to all participants. INT took part in a 16-week lifestyle program which provided a curriculum and practical strategies on 1) dietary and PA information based on national guidelines, 2) behavioural self-management tools, 3) food-label reading, supermarkets tour and cooking, 4) exercise sessions, and 5) peer-group support. Compliance was assessed using attendance records and weekly food/PA logs. Participants' motivations, perceived benefits and goals were assessed through facilitated discussion. Program acceptability feedback was collected through structured focus groups. Results: Although completion of weekly food/PA records was poor, attendance at information/education sessions (77% overall) and exercise participation (66% overall) was high, and compared with CON, multiple markers of body composition and cardio-metabolic health improved in INT. Participants reported that the most useful program components included food-label reading, cooking sessions, and learning new and different physical exercises, including home-based options. Participants also reported finding self-management techniques helpful, namely problem solving and short-term goal setting. The use of a group setting and supportive 'peer' leaders were found to be supportive. More frequent clinical assessment was suggested for future programs. Conclusion: This group-based lifestyle program achieved improvements in body composition and cardio-metabolic and physical fitness similar to individualised interventions which are more resource intensive to deliver. It confirmed that active training in lifestyle modification is more effective than passive provision of guidelines. Such programs should include social support and self-management techniques. Continued clinical follow up may be required for long-term maintenance in individuals attempting lifestyle behaviour change. Program facilitation by peers may help and should be further investigated in a community-based model.Tahna L Pettman, Gary MH Misan, Katherine Owen, Kate Warren, Alison M Coates, Jonathan D Buckley and Peter RC How

Knowledge translation strategies to improve the use of evidence in public health decision making in local government: intervention design and implementation plan

Background:&nbsp;Knowledge translation strategies are an approach to increase the use of evidence within policy and practice decision-making contexts. In clinical and health service contexts, knowledge translation strategies have focused on individual behavior change, however the multi-system context of public health requires a multi-level, multi-strategy approach. This paper describes the design of and implementation plan for a knowledge translation intervention for public health decision making in local government. Methods: Four preliminary research studies contributed findings to the design of the intervention: a systematic review of knowledge translation intervention effectiveness research, a scoping study of knowledge translation perspectives and relevant theory literature, a survey of the local government public health workforce, and a study of the use of evidence-informed decision-making for public health in local government. A logic model was then developed to represent the putative pathways between intervention inputs, processes, and outcomes operating between individual-, organizational-, and system-level strategies. This formed the basis of the intervention plan. Results: The systematic and scoping reviews identified that effective and promising strategies to increase access to research evidence require an integrated intervention of skill development, access to a knowledge broker, resources and tools for evidence-informed decision making, and networking for information sharing. Interviews and survey analysis suggested that the intervention needs to operate at individual and organizational levels, comprising workforce development, access to evidence, and regular contact with a knowledge broker to increase access to intervention evidence; develop skills in appraisal and integration of evidence; strengthen networks; and explore organizational factors to build organizational cultures receptive to embedding evidence in practice. The logic model incorporated these inputs and strategies with a set of outcomes to measure the intervention\u27s effectiveness based on the theoretical frameworks, evaluation studies, and decision-maker experiences. Conclusion: Documenting the design of and implementation plan for this knowledge translation intervention provides a transparent, theoretical, and practical approach to a complex intervention. It provides significant insights into how practitioners might engage with evidence in public health decision making. While this intervention model was designed for the local government context, it is likely to be applicable and generalizable across sectors and settings.</div

A cross-country study of mis-implementation in public health practice

Abstract Background Mis-implementation (i.e., the premature termination or inappropriate continuation of public health programs) contributes to the misallocation of limited public health resources and the sub-optimal response to the growing global burden of chronic disease. This study seeks to describe the occurrence of mis-implementation in four countries of differing sizes, wealth, and experience with evidence-based chronic disease prevention (EBCDP). Methods A cross-sectional study of 400 local public health practitioners in Australia, Brazil, China, and the United States was conducted from November 2015 to April 2016. Online survey questions focused on how often mis-termination and mis-continuation occur and the most common reasons programs end and continue. Results We found significant differences in knowledge of EBCDP across countries with upwards of 75% of participants from Australia (n = 91/121) and the United States (n = 83/101) reporting being moderately to extremely knowledgeable compared with roughly 60% (n = 47/76) from Brazil and 20% (n = 21/102) from China (p < 0.05). Far greater proportions of participants from China thought effective programs were never mis-terminated (12.2% (n = 12/102) vs. 1% (n = 2/121) in Australia, 2.6% (n = 2/76) in Brazil, and 1.0% (n = 1/101) in the United States; p < 0.05) or were unable to estimate how frequently this happened (45.9% (n = 47/102) vs. 7.1% (n = 7/101) in the United States, 10.5% (n = 8/76) in Brazil, and 1.7% (n = 2/121) in Australia; p < 0.05). The plurality of participants from Australia (58.0%, n = 70/121) and the United States (36.8%, n = 37/101) reported that programs often mis-continued whereas most participants from Brazil (60.5%, n = 46/76) and one third (n = 37/102) of participants from China believed this happened only sometimes (p < 0.05). The availability of funding and support from political authorities, agency leadership, and the general public were common reasons programs continued and ended across all countries. A program’s effectiveness or evidence-base—or lack thereof—were rarely reasons for program continuation and termination. Conclusions Decisions about continuing or ending a program were often seen as a function of program popularity and funding availability as opposed to effectiveness. Policies and practices pertaining to programmatic decision-making should be improved in light of these findings. Future studies are needed to understand and minimize the individual, organizational, and political-level drivers of mis-implementation

Prevalence and Interrelationships between Cardio-Metabolic Risk Factors in Abdominally Obese Individuals

OBJECTIVES: The aim of this study was to examine the prevalence of metabolic syndrome and identify relationships between clustering and severity of cardio-metabolic risk factors in abdominally obese adults. METHODS: Cardio-metabolic risk factors were assessed in a sample of 300 abdominally obese volunteers (233 females, 67 males, mean age 43.7 years) who were not being treated for diabetes, hypertension or dyslipidemia. Waist circumference (WC), blood pressure, fasting lipids, and glucose were measured and prevalence of metabolic syndrome was determined according to International Diabetes Federation (IDF) criteria. Correlation analysis and Poisson regression were used to examine associations between the presence of a particular risk factor and the propensity for clustering and derangement of other risk factors, using continuous data for risk factors and categorical data for number of metabolic syndrome components. RESULTS: In all, 53% had metabolic syndrome and only 16% were free of cardio-metabolic abnormalities. In order of importance, diastolic blood pressure (DBP), high-density lipoprotein cholesterol (HDL), and triglycerides (TGs) were most strongly associated with greater clustering of risk factors, with a one standard deviation difference being associated with a respective difference of 9.65, 1.23, and 0.12 in the number of risk factors present. A greater number of risk factors was associated with an increased derangement for any given risk factor, with this effect being greatest for dyslipidemia, as represented by the TG:HDL ratio. DISCUSSION: In abdominally obese individuals, DBP was strongly associated with metabolic syndome component clustering, which may reflect the pathogenic progression of metabolic syndrome, as DBP is likely to be elevated following establishment of other risk factors. Also, dyslipidemia was strongly related to the magnitude of derangement of cardio-metabolic risk factors which may indicate that increases in dyslipidemia may drive the pathogenic progression of metabolic syndrome once acquired.Tahna L.

Developing a Tool to Assess Implementation of Evidence-Based Chronic Disease Prevention in Public Health Settings Across Four Countries

Development of the 26-question survey included, a narrative literature review of extant measures in evidence-based chronic disease prevention (EBCDP); qualitative interviews with 50 chronic disease prevention practitioners in Australia, Brazil, China, and the United States; review by an expert panel of researchers in EBCDP; and test-retest reliability assessment. A convenience sample of practitioners working in chronic disease prevention in each country completed the survey twice (N=165). Overall, this tool produced good to moderately reliable responses. Generally, reliability of responses was higher among practitioners from Australia and the United States than China and Brazil

A Food Relief Charter for South Australia&mdash;Towards a Shared Vision for Pathways Out of Food Insecurity

Chronic food insecurity persists in high-income countries, leading to an entrenched need for food relief. In Australia, food relief services primarily focus on providing food to meet immediate need. To date, there has been few examples of a vision in the sector towards client outcomes and pathways out of food insecurity. In 2016, the South Australian Government commissioned research and community sector engagement to identify potential policy actions to address food insecurity. This article describes the process of developing a co-designed South Australian Food Relief Charter, through policy&ndash;research&ndash;practice collaboration, and reflects on the role of the Charter as both a policy tool and a declaration of a shared vision. Methods used to develop the Charter, and resulting guiding principles, are discussed. This article reflects on the intentions of the Charter and suggests how its guiding principles may be used to guide collective actions for system improvement. Whilst a Charter alone may be insufficient to create an integrated food relief system that goes beyond the provision of food, it is a useful first step in enabling a culture where the sector can have a unified voice to advocate for the prevention of food insecurity

Comparing knowledge, accessibility, and use of evidence-based chronic disease prevention processes across four countries

In this cross-sectional study, public health practitioners (N=400) from Australia, Brazil, China, and the United States completed a 26-question survey on EBCDP implementation

A qualitative exploration of contextual factors that influence dissemination and implementation of evidence-based chronic disease prevention across four countries

Abstract Background Little is known about the contextual factors affecting the uptake of evidence-based chronic disease interventions in the United States and in other countries. This study sought to better understand the contextual similarities and differences influencing the dissemination and implementation of evidence-based chronic disease prevention (EBCDP) in Australia, Brazil, China, and the United States. Methods Between February and July 2015, investigators in each country conducted qualitative, semi-structured interviews (total N = 50) with chronic disease prevention practitioners, using interview guides that covered multiple domains (e.g., use of and access to EBCDP interventions, barriers and facilitators to the implementation of EBCDP interventions). Results Practitioners across the four countries reported only a few programmatic areas in which repositories of EBCDP interventions were used within their workplace. Across countries, academic journals were the most frequently cited channels for accessing EBCDP interventions, though peers were commonly cited as the most useful. Lack of time and heavy workload were salient personal barriers among practitioners in Australia and the United States, while lack of expertise in developing and implementing EBCDP interventions was more pertinent among practitioners from Brazil and China. Practitioners in all four countries described an organizational culture that was unsupportive of EBCDP. Practitioners in Brazil, China and the United States cited an inadequate number of staff support to implement EBCDP interventions. A few practitioners in Australia and China cited lack of access to evidence. Partnerships were emphasized as key facilitators to implementing EBCDP interventions across all countries. Conclusions This study is novel in its cross-country qualitative exploration of multilevel constructs of EBCDP dissemination and implementation. The interviews produced rich findings about many contextual similarities and differences with EBCDP that can inform both cross-country and country-specific research and practice to address barriers and improve EBCDP implementation among the four countries long-term
