Health and Wellbeing Benefits from Nature Experiences in Tropical Settings Depend on Strength of Connection to Nature. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph181910149. [PMID: 34639451 PMCID: PMC8507985 DOI: 10.3390/ijerph181910149] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Revised: 09/20/2021] [Accepted: 09/24/2021] [Indexed: 12/21/2022]
Abstract
A growing number of policies and programmes in cities aim to increase the time people spend in nature for the health and wellbeing benefits delivered by such interactions. Yet, there is little research investigating the extent to which, and for whom, nature experiences deliver such benefits outside Europe, North America, and Australia. Here, we assessed the relationships between nature dose (frequency, duration, and intensity) and three mental wellbeing (depression, stress, and anxiety) and two physical health (high blood pressure, diabetes) outcomes in Singapore, an intensely urbanised tropical city. Our analyses accounted for individual factors, including socio-economic status, nature connection (nature relatedness), and whether people with poor health are prevented by their condition from visiting green spaces. Our results show that the association between nature dose (specifically duration) and mental wellbeing is moderated by a nature connection. Specifically, people with a stronger nature connection were less likely to be depressed, stressed, and anxious, regardless of the duration of their nature dose. For those with a weaker connection to nature, spending longer in nature was associated with being more depressed, stressed, and anxious. We did not find a relationship between nature dose and high blood pressure or diabetes. Our results highlight that the relationship between nature dose and wellbeing might vary substantially among cities.

Abstract
The Get Healthy Information and Coaching Service (GHS), an effective 6-month telephone-based healthy lifestyle coaching service, includes a population-targeted diabetes prevention module (DPM) tailored for adults at risk for type 2 diabetes. This study determined DPM's reach and impact on anthropometric and lifestyle risk factors. Pre-post evaluation design examined self-reported anthropometric (body weight, waist circumference) and lifestyle risk factors (physical activity and dietary behaviors) of DPM participants. Descriptive and chi-square analyses were performed on sociodemographic variables. Behavioral changes were assessed using matched pairs analysis, independent samples analysis, and multivariate analysis. There were 4,222 DPM participants (76.0% female; 75.9% aged ≥ 50; 95.4% spoke English at home). The DPM included higher proportions of older adults (≥50) (75.9% vs. 46.5%; p < .001), retirees (28.7% vs. 18.5%; p < .0001), less educated (33.3% vs. 24.9%; p < .0001), more disadvantaged (41.7% vs. 34.8%; p < .001) and living in regional or rural areas (43.2% vs. 39.8%; p < .001) than the GHS program. DPM participants reported significant improvements at six months for all anthropometric (-3.3 kg weight; -1.2 BMI units; -4.3 cm waist circumference) and behavioral risk factors (+0.2 fruit serves/day; +0.7 vegetables serves/day; -0.2 sweetened drinks/day; -0.2 takeaway meals/week; +1.1 30-min walking sessions/week; +0.7 30-min moderate activity sessions/week; +0.2 20-min vigorous activity sessions/week). Nearly one-third (31.1%) of participants lost ≥5% body weight. The DPM reached priority population groups, those typically underrepresented in diabetes prevention programs and resulted in clinically relevant improvements in anthropometric and lifestyle risk factors in adults at increased risk for type 2 diabetes.

Healthy Weight for Life programme: Evaluating the practice and effectiveness of a weight loss maintenance programme in the private health insurance setting. SAGE Open Med 2019; 7:2050312119873814. [PMID: 31516705 PMCID: PMC6719468 DOI: 10.1177/2050312119873814] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2019] [Accepted: 08/13/2019] [Indexed: 02/05/2023] Open
Abstract
Background Australian private health insurers are increasingly involved in the delivery of chronic disease management programmes to their members, recognising the importance of decreasing and managing lifestyle risk factors and the impact such factors have on health service utilisation. One such secondary prevention programme is the Healthy Weight for Life programme, an intensive weight loss and lifestyle modification programme that has been designed for overweight and obese private health insurance members in Australia. Together with the insurer, the Healthy Weight for Life service provider developed and implemented a long-term maintenance programme that supports participants who complete the Healthy Weight for Life programme to maintain the weight loss they achieved during the programme. Various studies have shown that evidence-based weight management programmes can be effective; however, the results may vary in different contexts. Objective This article presents the evaluation rationale and framework designed to assess the process and impact of the long-term maintenance programme on weight loss maintenance, other health-related benefits and participants' experience with the programme. Methods The evaluation will comprise a number of inter-related sub-studies balancing evaluation of programme effectiveness and implementation. The maintenance programme presented a unique opportunity for researchers to partner with private health insurance and a service provider to assess a real-world programme in the under-researched area of weight loss maintenance in this setting and emphasises the importance of evaluating such programmes given the potential the private health insurance context has in the future delivery of health care.

JOURNAL OF EDUCATION AND HEALTH PROMOTION 2018; 7:141. [PMID: 30596113 PMCID: PMC6282482 DOI: 10.4103/jehp.jehp_145_18] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 05/23/2018] [Accepted: 08/04/2018] [Indexed: 06/07/2023]
Abstract
PURPOSE Noncommunicable disease (NCD) prevention is emerging as a public health priority in developing countries. For better health outcome in these countries, it is necessary to understand the different community-based interventions developed and implemented across the world. OBJECTIVE The objective of the current review is to identify the best strategies used in community-based health intervention (CBHI) programs across the world. MATERIALS AND METHODS For review, we searched in PubMed and Google Scholar with the keywords "community based," "health interventions," "health promotions," "primary prevention," chronic diseases," "lifestyle-related diseases," and "NCD." Data were extracted using predesigned data extraction form. CBHI studies detailing their intervention strategies only were included in the review. RESULTS Out of 35 articles reviewed, 14 (40%) were randomized control trials, while 18 (51.4%) were quasi-experimental design. Individual level (n = 14), group level (n = 5), community level (n = 6), and policy level (n = 4) intervention strategies were identified. Twenty-three (64%) studies were based on interventions for 1 year and above. Twenty-eight (80%) studies were intervened among specific populations such as Latinos and so on. CONCLUSION Successful programs advocate for a package or a chain of interventions than a single intervention. The type of interventions at different levels, namely individual, group, community, and policy levels vary across studies, but individual, and group level interventions are more frequently used.

Implementation of the DP-TRANSFERS project in Catalonia: A translational method to improve diabetes screening and prevention in primary care. PLoS One 2018; 13:e0194005. [PMID: 29543842 PMCID: PMC5854335 DOI: 10.1371/journal.pone.0194005] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2017] [Accepted: 02/22/2018] [Indexed: 01/06/2023] Open
Abstract
Background The DE-PLAN-CAT project (Diabetes in Europe–Prevention using lifestyle, physical activity and nutritional intervention–Catalonia) has shown that an intensive lifestyle intervention is feasible in the primary care setting and substantially reduces the incidence of diabetes among high-risk Mediterranean participants. The DP-TRANSFERS project (Diabetes Prevention–Transferring findings from European research to society) is a large-scale national programme aimed at implementing this intervention in primary care centres whenever feasible. Methods A multidisciplinary committee first evaluated the programme in health professionals and then participants without diabetes aged 45–75 years identified as being at risk of developing diabetes: FINDRISC (Finnish Diabetes Risk Score)>11 and/or pre-diabetes diagnosis. Implementation was supported by a 4-channel transfer approach (institutional relationships, facilitator workshops, collaborative groupware, programme website) and built upon a 3-step (screening, intervention, follow-up) real-life strategy. The 2-year lifestyle intervention included a 9-hour basic module (6 sessions) and a subsequent 15-hour continuity module (10 sessions) delivered by trained primary healthcare professionals. A 3-level (centre, professionals and participants) descriptive analysis was conducted using cluster sampling to assess results and barriers identified one year after implementation. Results The programme was started in June-2016 and evaluated in July-2017. In all, 103 centres covering all the primary care services for 1.4 million inhabitants (27.9% of all centres in Catalonia) and 506 professionals agreed to develop the programme. At the end of the first year, 83 centres (80.6%) remained active and 305 professionals (60.3%) maintained regular web-based activities. Implementation was not feasible in 20 centres (19.4%), and 5 main barriers were prioritized: lack of healthcare manager commitment; discontinuity of the initial effort; substantial increase in staff workload; shift in professional status and lack of acceptance. Overall, 1819 people were screened and 1458 (80.1%) followed the lifestyle intervention, with 1190 (81.6% or 65.4% of those screened) participating in the basic module and 912 in the continuity module (62.5% or 50.1%, respectively). Conclusions A large-scale lifestyle intervention in primary care can be properly implemented within a reasonably short time using existing public healthcare resources. Regrettably, one fifth of the centres and more than one third of the professionals showed substantial resistance to performing these additional activities.

Abstract
OBJECTIVES We sought to determine whether screening for anxiety and depression, an emerging risk factor for type 2 diabetes (T2D), adds clinically meaningful information beyond current T2D risk assessment tools. DESIGN Prospective cohort. PARTICIPANTS AND SETTING The 45 and Up Study is a large-scale prospective cohort of men and women aged 45 years and over, randomly sampled from the general population of New South Wales, Australia. 51 588 participants without self-reported diabetes at baseline (2006-2009) were followed up for approximately 3 years (2010). METHODS T2D status was determined by self-reported doctor who diagnosed diabetes after the age of 30 years, and/or current use of metformin. Current symptoms of anxiety and/or depression were measured by the 10-item Kessler Psychological Distress Scale (K10). We determined the optimal cut-off point for K10 for predicting T2D using Tjur's R2 and tested risk models with and without the K10 using logistic regression. We assessed performance measures for the incremental value of the K10 using the area under the receiver operating characteristic (AROC), net reclassification improvement (NRI) and net benefit (NB) decision analytics with sensitivity analyses. RESULTS T2D developed in 1076 individuals (52.4% men). A K10 score of ≥19 (prevalence 8.97%), adjusted for age and gender, was optimal for predicting incident T2D (sensitivity 77%, specificity 53% and positive predictive value 3%; OR 1.70 (95% CI 1.41 to 2.03, P<0.001). K10 score predicted incident T2D independent of current risk models, but did not improve corresponding AROC, NRI and NB statistics. Sensitivity analyses showed that this was partially explained by the baseline model and the small effect size of the K10 that was similar compared with other risk factors. CONCLUSIONS Anxiety and depressing screening with the K10 adds no meaningful incremental value in addition to current T2D risk assessments. The clinical importance of anxiety and depression screening in preventing T2D requires ongoing consideration.

Abstract
Background: Seven landmark randomised controlled trials, with some that began as early as the 1990s, observed the prediabetic state, namely, impaired glucose tolerance and impaired fasting glucose conditions, against the impact of lifestyle interventions such as physical activity, to prevent or delay the onset of type 2 diabetes mellitus. In addition to the landmark trials, this systematic review examines 14 studies that retained a focus on prediabetic individuals and measured the efficacy of physical activity on improving glucose tolerance. Results: Type, duration and intensity of structured physical activity can have unique benefits to prediabetic individuals. It is posited that diabetes prevention programmes must target prediabetic individuals as belonging to a high-risk group, separate and distinct from those identified with overall risk factors. While the transition from prediabetes to type 2 diabetes mellitus is not completely deterministic, the conversion rate is phenomenally higher among those with impaired glucose tolerance than those with normal glucose levels. Conclusion: Tenets of health behaviour models do support inferences that prediabetic individuals are potentially more inclined to weighing the risks and benefits of progressive illnesses and would therefore be more receptive to active participation in interventions. More research is required to develop evidence-based diabetes prevention programmes linked to structured physical activity intervention.

Abstract
AIM There is strong and consistent evidence from large scale randomised controlled trials that type 2 diabetes can be prevented or delayed through lifestyle modification which improves diet quality, increases physical activity and achieves weight loss in people at risk. Worldwide, the prevalence of type 2 diabetes is increasing in individuals of Chinese descent. Culturally tailored programs are required to address the risk in the Chinese population. This paper analyses effectiveness of a culturally tailored community-based lifestyle modification program (Sydney Diabetes Prevention Program (SDPP)) targeting Mandarin speakers. The SDPP was a 12 month translational study aiming to promote increased physical activity and dietary changes. Effectiveness was assessed through the improvement of anthropometric, metabolic, physical activity and dietary outcomes and number of goals met. METHODS Seventy-eight Mandarin-speaking participants at a high risk (Australian Diabetes Risk, AUSDRISK≥15) of developing diabetes were recruited for this study. RESULTS In this cohort, waist circumference, total cholesterol and fat intake significantly improved at the 12-month review. In comparison to the English-speaking stream, the Mandarin-speaking stream achieved fewer improvements in outcomes and goals. CONCLUSION The SDPP was not effective in reducing the risk factors associated with developing type 2 diabetes in this cohort of high risk Mandarin-speaking individuals living in Sydney.

Abstract
Clinical trials have demonstrated the efficacy of lifestyle modification for the prevention of type 2 diabetes mellitus but it was achieved at higher cost than can be sustained in routine health services. The first clinical trial to report was the Finnish Diabetes Prevention Study. This paper describes how Australia worked with Finnish colleagues to adapt the findings of that study to achieve a statewide diabetes prevention program. Small evaluative, effectiveness trials have been conducted in a number of countries to see if the results of the clinical trials can be replicated in routine health services. The Australian evaluative trial, Greater Green Triangle Diabetes Prevention Program is described in detail to demonstrate the ingredients for success in moving a program from one country to another. Few countries have managed to scale up from evaluative trials to statewide or national programs. The Australian experience is described in detail including lessons learned about what reduced the effectiveness, particularly the need for policy makers in government, people from the implementing organisation and researchers to work together from the start of the evaluative trial and throughout the first 5 years of a national program.

Abstract
BACKGROUND Type 2 diabetes is impacting millions of people globally; however, many future cases can be prevented through lifestyle changes and interventions. Primary care is an important setting for diabetes prevention, for at-risk populations, because it is a patient's primary point of contact with the health care system and professionals can provide lifestyle counselling and support, as well as monitoring health outcomes. These are all essential elements for diabetes prevention for at-risk adults. AIM To understand the factors related to the delivery and uptake of type 2 diabetes prevention interventions within primary care in higher income countries. METHODS For this narrative systematic review, we combined qualitative and quantitative studies of diabetes prevention within a primary care setting for patients at-risk of developing the condition. We used an iterative approach for evidence collection, which included using several databases (MEDLINE, Embase, Pysch info, BNI, SSCI, CINAHL, ASSIA), where we combined diabetes terms with primary care terms. Narrative and thematic synthesis were utilised to identify the prominent themes emerging from the data. RESULTS A database of 6646 records was screened by the research team, and 18 papers were included. Three major themes were identified in this review. The first theme of context and setting of diabetes progression includes the risk and progression of diabetes, primary care as a setting, and where the responsibility for change is thought to lie. This review also found mixed views on the value of preventative services within primary care. The second theme focused on the various patient factors associated with diabetes prevention such as a patient's motivation to modify their current lifestyle, perceptions and knowledge (or lack thereof) of the impacts of diabetes, lack of follow-up in healthcare settings, and trust in healthcare professionals. The third theme was centred on professional factors impacting on diabetes prevention which included workload, time constraints, resources, self-efficacy and knowledge as well as professionals' perception of patient motivations towards change. CONCLUSION This review explored the factors influencing diabetes prevention in primary care, and identified the context of prevention, as well as patient and professional factors related to preventative services being offered in primary care. This systematic review complements previous reviews of real-world settings by exploring the significant factors in prevention, and the findings are relevant to academics, policymakers, patients and practitioners interested in understanding the factors associated with the delivery and uptake of diabetes prevention interventions.

[PMID: 28412640 DOI: 10.1016/j.socscimed.2017.04.008] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2016] [Revised: 04/01/2017] [Accepted: 04/07/2017] [Indexed: 12/16/2022]
Abstract
BACKGROUND Although living in a hilly environment may promote muscular activity in the daily lives of residents, and such activity may prevent diabetes mellitus, few studies have focused on the impact of living in a hilly environment on diabetes mellitus. The purpose of this study was to investigate the impact of a hilly neighborhood environment on DM in older people. METHODS We used data from the Japan Gerontological Evaluation Study, a population-based, cross-sectional study of individuals aged 65 or older without long-term care needs in Japan, which was conducted in 2010. A total of 8904 participants in 46 neighborhoods had responded to the questionnaire and undergone a health check. Diabetes mellitus was diagnosed as HbA1c ≥ 6.5% and those undergoing treatment for diabetes mellitus. Poorly controlled diabetes mellitus was diagnosed in those without other chronic diseases who had an HbA1c > 7.5%, and in those with other chronic diseases if their HbA1c was >8.0%. Neighborhood environment was evaluated based on the percentage of positive responses in the questionnaire and geographical information system data. A multilevel analysis was performed, adjusted for individual-level risk factors. Furthermore, sensitivity analysis was conducted for those who were undergoing treatment for diabetes mellitus (n = 1007). RESULTS After adjustment for other physical environmental and individual covariates, a 1 interquartile range increase (1.48°) in slope in the neighborhood decreased the risk of poorly controlled diabetes mellitus by 18% (odds ratio [OR]: 0.82, 95% confidence interval [CI]: 0.70-0.97). Sensitivity analysis confirmed that larger slopes in the neighborhood showed a significant protective effect against diabetes mellitus among those who were undergoing treatment for diabetes mellitus (OR: 0.73, 95% CI: 0.59-0.90). CONCLUSION A hilly neighborhood environment was not associated with diabetes mellitus, but was protective against poorly controlled diabetes mellitus.

Abstract
BACKGROUND Indigenous Australians and New Zealanders have a significantly shorter life expectancy than non-Indigenous people, mainly due to differences in prevalence of chronic diseases. Physical activity helps in the prevention and management of chronic diseases, however, activity levels are lower in Indigenous than in non-Indigenous people. OBJECTIVE To synthesise the literature on the effects of physical activity interventions for Indigenous people in Australia and New Zealand on activity levels and health outcomes. METHODS The Cochrane Library, MEDLINE, SPORTSDiscus and PsycINFO were searched for peer-reviewed articles and grey literature was searched. Interventions targeted Indigenous people in Australia or New Zealand aged 18+ years and their primary or secondary aim was to increase activity levels. Data were extracted by one author and verified by another. Risk of bias was assessed independently by two authors. Data were synthesised narratively. RESULTS 407 records were screened and 13 studies included. Interventions included individual and group based exercise programs and community lifestyle interventions of four weeks to two years. Six studies assessed physical activity via subjective (n = 4) or objective (n = 2) measures, with significant improvements in one study. Weight and BMI were assessed in all but one study, with significant reductions reported in seven of 12 studies. All five studies that used fitness tests reported improvements, as did four out of eight measuring blood pressure and seven out of nine in clinical markers. CONCLUSIONS There was no clear evidence for an effect of physical activity interventions on activity levels, however, there were positive effects on activity related fitness and health outcomes. TRIAL REGISTRATION The review protocol was registered with PROSPERO (registration number: CRD42015016915 ).

Abstract
OBJECTIVE An accounting of the resources necessary for implementation of efficacious programs is important for economic evaluations and dissemination. METHODS A programmatic costs analysis was conducted prospectively in conjunction with an efficacy trial of Fuel Your Life (FYL), a worksite translation of the Diabetes Prevention Program. FYL was implemented through three different modalities, Group, Phone, and Self-study, using a micro-costing approach from both the employer and societal perspectives. RESULTS The Phone modality was the most costly at $354.6 per participant, compared with $154.6 and $75.5 for the Group and Self-study modalities, respectively. With the inclusion of participant-related costs, the Phone modality was still more expensive than the Group modality but with a smaller incremental difference ($461.4 vs $368.1). CONCLUSIONS This level of cost-related detail for a preventive intervention is rare, and our analysis can aid in the transparency of future economic evaluations.

Abstract
BACKGROUND Meeting global health challenges requires effective behaviour change interventions (BCIs). This depends on advancing the science of behaviour change which, in turn, depends on accurate intervention reporting. Current reporting often lacks detail, preventing accurate replication and implementation. Recent developments have specified intervention content into behaviour change techniques (BCTs) - the 'active ingredients', for example goal-setting, self-monitoring of behaviour. BCTs are 'the smallest components compatible with retaining the postulated active ingredients, i.e. the proposed mechanisms of change. They can be used alone or in combination with other BCTs' (Michie S, Johnston M. Theories and techniques of behaviour change: developing a cumulative science of behaviour change. Health Psychol Rev 2012;6:1-6). Domain-specific taxonomies of BCTs have been developed, for example healthy eating and physical activity, smoking cessation and alcohol consumption. We need to build on these to develop an internationally shared language for specifying and developing interventions. This technology can be used for synthesising evidence, implementing effective interventions and testing theory. It has enormous potential added value for science and global health. OBJECTIVE (1) To develop a method of specifying content of BCIs in terms of component BCTs; (2) to lay a foundation for a comprehensive methodology applicable to different types of complex interventions; (3) to develop resources to support application of the taxonomy; and (4) to achieve multidisciplinary and international acceptance for future development. DESIGN AND PARTICIPANTS Four hundred participants (systematic reviewers, researchers, practitioners, policy-makers) from 12 countries engaged in investigating, designing and/or delivering BCIs. Development of the taxonomy involved a Delphi procedure, an iterative process of revisions and consultation with 41 international experts; hierarchical structure of the list was developed using inductive 'bottom-up' and theory-driven 'top-down' open-sort procedures (n = 36); training in use of the taxonomy (1-day workshops and distance group tutorials) (n = 161) was evaluated by changes in intercoder reliability and validity (agreement with expert consensus); evaluating the taxonomy for coding interventions was assessed by reliability (intercoder; test-retest) and validity (n = 40 trained coders); and evaluating the taxonomy for writing descriptions was assessed by reliability (intercoder; test-retest) and by experimentally testing its value (n = 190). RESULTS Ninety-three distinct, non-overlapping BCTs with clear labels and definitions formed Behaviour Change Technique Taxonomy version 1 (BCTTv1). BCTs clustered into 16 groupings using a 'bottom-up' open-sort procedure; there was overlap between these and groupings produced by a theory-driven, 'top-down' procedure. Both training methods improved validity (both p < 0.05), doubled the proportion of coders achieving competence and improved confidence in identifying BCTs in workshops (both p < 0.001) but did not improve intercoder reliability. Good intercoder reliability was observed for 80 of the 93 BCTs. Good within-coder agreement was observed after 1 month (p < 0.001). Validity was good for 14 of 15 BCTs in the descriptions. The usefulness of BCTTv1 to report descriptions of observed interventions had mixed results. CONCLUSIONS The developed taxonomy (BCTTv1) provides a methodology for identifying content of complex BCIs and a foundation for international cross-disciplinary collaboration for developing more effective interventions to improve health. Further work is needed to examine its usefulness for reporting interventions. FUNDING This project was funded by the Medical Research Council Ref: G0901474/1.

Abstract
BACKGROUND Compelling evidence has been accumulated to support the effectiveness of intensive lifestyle intervention in delaying progression to Type 2 diabetes even in people identified as being at high risk determined by the Finnish diabetes risk score. The DE-PLAN-CAT project (diabetes in Europe-prevention using lifestyle, physical activity and nutritional intervention-Catalonia) evidenced that intensive lifestyle intervention was feasible and cost-effective on a short scale in real-life primary care settings, at least over 4 years. However, transferring such lifestyle interventions to society remains the major challenge of research in the field of diabetes prevention. METHODS/DESIGN The derived DP-TRANSFERS (diabetes prevention-transferring findings from European research to society) is a large scale national programme aimed at translating a tailored lifestyle intervention to the maximum of primary care centres where feasible through a core proposal agreed with all the partners. The method is built upon a 3-step (screening, intervention and follow-up) real-life, community-wide structure on the basis of a dual intensity lifestyle intervention (basic and continuity modules) and supported by a 4-channel transfer strategy (institutional relationships, facilitators' workshops, collaborative groupware and programme WEB page). Participation will initially cover nine health departments (7 million inhabitants) through nine coordinating centres located in metropolitan (3.2 million), semi-urban (2.9 million) and rural (0.9 million) areas from which it is expected accessing 25 % of all primary care settings, equivalent to 90 associated centres (1.6-1.8 million people) with an estimate of 0.32 million participants aged 45-75 years at high risk of future development of diabetes. To ascertain sustainability, effect, satisfaction and quality of the translation programme statistical analyses will be performed from both the entire population (facilitators and participants) and a stratified representative sample obtained by collecting data from at least 920 participants. DISCUSSION The DP-TRANSFERS will use a strategy of approach to society consistent with the impact of the disease and the fast accessibility provided by primary care settings in Catalonia. Both the widespread effect of the lifestyle intervention and the translational process itself could be assessed.

Abstract
AIMS/HYPOTHESIS The Sydney Diabetes Prevention Program (SDPP) was a community-based type 2 diabetes prevention translational research study with screening and recruitment in the primary health care setting. We aimed to investigate the program's effectiveness in reducing risk factors for diabetes as well as the program's reach, adoption and implementation. METHODS 1238 participants aged 50-65 years at high-risk of developing type 2 diabetes were recruited by primary care physicians in the greater Sydney region. The intervention, delivered by trained allied health professionals, included an initial consultation, three group sessions/individual sessions, three follow-up phone calls, and a final review at 12 months. Biomarkers and behavioural goals were compared between baseline and 12 months. RESULTS At baseline, the mean age of those who entered the program was 58.8 ± 4.4 years, 63% female, and the mean body mass index was 31.6 ± 5.2 kg/m(2). There was a significant weight reduction of 2 ± 4.3 kg (p<0.02) in the 850 participants who completed the 12-month follow-up accompanied by improvements in diet (total fat, saturated fat, and fibre intake) and physical activity. There were also significant reductions in waist circumference 2.6 ± 4.7 cm (p<0.001) and total cholesterol -0.2 ± 0.8 mmol/L (p<0.001) but not blood glucose. The diabetes risk reduction was estimated to be 30%, consistent with similar trials. CONCLUSIONS/INTERPRETATION This study demonstrates that a community-based lifestyle modification program is effective in reducing important risk factors for diabetes in individuals at high-risk of developing type 2 diabetes.

Abstract
BACKGROUND Lifestyle modification programs (LMPs) can provide individuals with behavioral skills to sustain long-term changes to their physical activity (PA) levels and dietary habits. Yet, there is much work to be done in the translation of these programs to community settings. PURPOSE This review identified LMPs that focused on changing both PA and dietary behaviors and examined common features and barriers faced in their translation to community settings. METHODS A search of multiple online databases was conducted to identify LMPs that included participants over the age of 18 who enrolled in LMPs, offered in community settings, and had the goal of improving both PA and dietary behaviors. Data were extracted on participant demographics, study design characteristics, and study outcome variables including changes in PA, dietary habits, body weight, and clinical outcomes. RESULTS We identified 27 studies that met inclusion criteria. Despite high levels of retention and adherence to the interventions, varying levels of success were observed in increasing PA levels, improving dietary habits, reducing body weight, and improving clinic outcomes. CONCLUSION LMPs addressing issues of PA and dietary habits can be successfully implemented in a community setting. However, inconsistent reporting of key components in the translation of these studies (participant recruitment, utilization of behavioral strategies) may limit their replication and advancement of future programs. Future efforts should better address issues such as identifying barriers to participation and program implementation, utilization of community resources, and evaluating changes across multiple health behaviors.

Abstract
About 2 million Australians have prediabetes and are at high risk of developing type 2 diabetes. Type 2 diabetes is a fast-growing epidemic and the economic costs are estimated to be $14.6 billion per year in Australia. Strong evidence from randomised controlled trials shows type 2 diabetes can be prevented in up to 58% of people at high risk, through structured lifestyle intervention. Good evidence and experience obtained from translational studies in Australia shows we can deliver effective community-based prevention programs. To be effective, a national strategy for prevention of type 2 diabetes should involve two concurrent approaches - a targeted approach aimed at those most at risk (ie, with prediabetes) combined with an environments, systems and behaviour approach for the entire population. Australia's current efforts in both these areas are not nationwide, not large scale and often not sustained.

Abstract
AIMS The primary aim was to describe characteristics of men identified at high-risk for Type 2 diabetes mellitus (T2DM) using the Australian diabetes risk assessment (AUSDRISK) tool. Secondary aims were to determine the prevalence of pre-diabetes and metabolic syndrome in these men. METHODS Men (n=209) completed the AUSDRISK tool, with 165 identified as high-risk for T2DM (score ≥ 12, maximum 38). Demographic, anthropometric, physiological and behavioural outcomes were assessed for 101 men. Comparisons (one-way ANOVA) among three AUSDRISK score groups (12-15, 16-19, ≥ 20) were performed (significance level, P<0.05). RESULTS Common risk factors (percentages) among high-risk men were waist circumference (>90 cm; 93%), age (>44 years; 79%), physical activity level (< 150 min wk(-1); 59%), family history of diabetes (39%) and previously high blood glucose levels (32%). Men with AUSDRISK scores ≥ 20 had higher (mean ± SD) HbA1C (6.0 ± 0.4% [42 ± 4.4 mmol.mol(-1)], P<0.001), FPG (5.3 ± 0.6 mmol.L(-1), P=0.001) and waist circumference (113.2 ± 9.8 cm, P=0.026) than men with scores of 12-15. Mean FPG for the sample was 5.0 ± 0.6 mmol.L(-1), whereas mean HbA1C was 5.8 ± 0.5% [40 ± 5.5 mmol.mol(-1)]. Pre-diabetes prevalence was 70% and metabolic syndrome prevalence was 62%. CONCLUSIONS The AUSDRISK tool identified men who were mostly older than 44, and had large waist circumferences and elevated HbA1C. These findings provide evidence supporting the usefulness of the AUSDRISK screening tool for T2DM screening in clinical and research settings.

Abstract
BACKGROUND Following a workshop with people with multiple conditions, the Chronic Illness Alliance undertook a literature review to explore current literature about multiple conditions. METHODS The literature search was performed using Medline, CINAHL, Google Scholar and Cochrane Library employing an extensive list of search terms and limited to English language journals between 1999 and 2009. Inclusion criteria for articles were those articles focussing on issues identified by consumers with more than one chronic illness and the health services working with them. RESULTS The results reported in this article are definitions of multiple conditions, safety and quality of services, risks and benefits of treatments for multiple and rare conditions and coordination of services. DISCUSSION The impact of multiple conditions or multimorbidities on health services has been researched internationally and identifies the barriers to good health care when multiple conditions are not recognized. While the issues for consumers with more than one condition are not well recognized, the barriers identified by the literature are of great importance to consumers. CONCLUSIONS This review demonstrates that services and policies in Australia require specific reforms to better meet the needs of people with multiple conditions.

Abstract
Type 2 Diabetes Mellitus (T2DM) and Gestational Diabetes (GDM) are important and escalating problems worldwide. GDM increases the risk of complications in pregnancy and birth, as well as a 1 in 2 chance of developing T2DM later in life. The burden of GDM extends to offspring, who have an increased risk of obesity and diabetes-further perpetuating the cycle of diabetes within families. Clinical trial evidence demonstrates T2DM incidence reduced by up to 50% for women with GDM with nutrition and physical activity changes and the economic modeling suggests cost effectiveness. The key diet-related changes to reduce T2DM risk are reviewed, in addition to breastfeeding. The difficulties associated with the delivery of dietary and lifestyle behaviour change to women after GDM are discussed and focus on: complex healthcare system interactions needed for care delivery; women finding postpartum self-care challenging; and low levels of awareness being present across the board. In addition, studies currently underway to improve care provision in this important area will be examined.

People with multiple unhealthy lifestyles are less likely to consult primary healthcare. BMC FAMILY PRACTICE 2014; 15:126. [PMID: 24965672 PMCID: PMC4083035 DOI: 10.1186/1471-2296-15-126] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/04/2014] [Accepted: 06/19/2014] [Indexed: 12/13/2022]
Abstract
BACKGROUND Behavioural interventions are often implemented within primary healthcare settings to prevent type 2 diabetes and other lifestyle-related diseases. Although smoking, alcohol consumption, physical inactivity and poor diet are associated with poorer health that may lead a person to consult a general practitioner (GP), previous work has shown that unhealthy lifestyles cluster among low socioeconomic groups who are less likely to seek primary healthcare. Therefore, it is uncertain whether behavioural interventions in primary healthcare are reaching those in most need. This study investigated patterns of GP consultations in relation to the clustering of unhealthy lifestyles among a large sample of adults aged 45 years and older in New South Wales, Australia. METHODS A total of 267,153 adults participated in the 45 and Up Study between 2006 and 2009, comprising 10% of the equivalent demographic in the state of New South Wales, Australia (response rate: 18%). All consultations with GPs within 6 months prior and post survey completion were identified (with many respondents attending multiple GPs) via linkage to Medicare Australia data. An index of unhealthy lifestyles was constructed from self-report data on adherence to published guidelines on smoking, alcohol consumption, diet and physical activity. Logistic and zero-truncated negative binomial regression models were used to analyse: (i) whether or not a person had at least one GP consultation within the study period; (ii) the count of GP consultations attended by each participant who visited a GP at least once. Analyses were adjusted for measures of health status, socioeconomic circumstances and other confounders. RESULTS After adjustment, participants scoring 7 unhealthy lifestyles were 24% more likely than persons scoring 0 unhealthy lifestyles not to have attended any GP consultation in the 12-month time period. Among those who attended at least one consultation, those with 7 unhealthy lifestyles reported 7% fewer consultations than persons with 0 unhealthy lifestyles. No effect modification was observed. CONCLUSION To optimise the prevention of lifestyle-related diseases, interventions for positive behavioural change need to incorporate non-primary healthcare settings in order to reach people with multiple unhealthy lifestyles.

Abstract
BACKGROUND An inequitable distribution of parks and other 'green spaces' could exacerbate health inequalities if people on lower incomes, who are already at greater risk of preventable diseases, have poorer access. METHODS The availability of green space within 1 kilometre of a Statistical Area 1 (SA1) was linked to data from the 2011 Australian census for Sydney (n = 4.6 M residents); Melbourne (n = 4.2 M); Brisbane (n = 2.2 M); Perth (n = 1.8 M); and Adelaide (n = 1.3 M). Socioeconomic circumstances were measured via the percentage population of each SA1 living on < $21,000 per annum. Negative binomial and logit regression models were used to investigate association between the availability of green space in relation to neighbourhood socioeconomic circumstances, adjusting for city and population density. RESULTS Green space availability was substantively lower in SA1s with a higher percentage of low income residents (e.g. an incidence rate ratio of 0.82 (95% confidence interval (95% CI) 0.75, 0.89) was observed for SA1s containing ≥20% versus 0-1% low income residents). This association varied between cities (p < 0.001). Adelaide reported the least equitable distribution of green space, with approximately 20% greenery in the most affluent areas versus 12% availability in the least affluent. Although Melbourne had a smaller proportion of SA1s in the top quintile of green space availability (13.8%), the distribution of greenery was the most equitable of all the cities, with only a 0.5% difference in the availability of green space between SA1s containing 0-1% low income households versus those with ≥20%. Inequity of access, however, was reported across all cities when using logit regression to examine the availability of at least 20% (odds ratio 0.74, 95% CI 0.59, 0.93) or 40% (0.45, 0.29, 0.69) green space availability in the more disadvantaged versus affluent neighbourhoods. CONCLUSION Affirmative action on green space planning is required to redress the socioeconomic inequity of access to this important public health resource.

Abstract
OBJECTIVE Lifestyle interventions for type 2 diabetes mellitus (T2DM) are best positioned for success if participants live in supportive neighborhood environments. Deprived neighborhoods increase T2DM risk. Parks and other "green spaces" promote active lifestyles and therefore may reduce T2DM risk. We investigated association between neighborhood green space and the risk of T2DM in a large group of adult Australians. RESEARCH DESIGN AND METHODS Multilevel logit regression was used to fit associations between medically diagnosed T2DM and green space exposure among 267,072 participants in the 45 and Up Study. Green space data were obtained from the Australian Bureau of Statistics, and exposure was calculated using a 1-km buffer from a participant's place of residence. Odds ratios (ORs) were controlled for measures of demographic, cultural, health, diet, active lifestyles, socioeconomic status, and neighborhood circumstances. RESULTS The rate of T2DM was 9.1% among participants in neighborhoods with 0-20% green space, but this rate dropped to approximately 8% for participants with over 40% green space within their residential neighborhoods. The risk of T2DM was significantly lower in greener neighborhoods, controlling for demographic and cultural factors, especially among participants residing in neighborhoods with 41-60% green space land use (OR 0.87; 95% CI 0.83-0.92). This association was consistent after controlling for other explanatory variables and did not vary according to neighborhood circumstances. CONCLUSIONS People in greener surroundings have a lower risk of T2DM. Planning, promoting, and maintaining local green spaces is important in multisector initiatives for addressing the T2DM epidemic.

Abstract
BACKGROUND AND AIMS Transferring the results from clinical trials on type 2 diabetes prevention is the objective of the Diabetes in Europe-Prevention using Lifestyle, Physical Activity and Nutritional intervention (DE-PLAN) project in Catalonia, whose cost-effectiveness analysis is now presented. PATIENTS AND METHODS A prospective cohort study was performed in primary care involving individuals without diagnosed diabetes aged 45-75 years (n=2054) screened using the questionnaire Finnish Diabetes Risk Score (FINDRISC) and a subsequent oral glucose tolerance test. Where feasible, high-risk individuals who were identified (n=552) were allocated sequentially to standard care (n=219), a group-based (n=230) or an individual-level (n=103) intensive (structured programme of six hours using specific teaching techniques) lifestyle intervention (n=333). The primary outcome was the development of diabetes (WHO). We evaluated the cost of resources used with comparison of standard care and the intervention groups in terms of effectiveness and quality of life (15D questionnaire). RESULTS After 4.2-year median follow-up, the cumulative incidences were 18.3% (14.3-22.9%) in the intensive intervention group and 28.8% (22.9-35.3%) in the standard care group (36.5% relative-risk-reduction). The corresponding 4-year HR was 0.64 (0.47-0.87; P<.004). The incremental cost induced by intensive intervention compared with the standard was 106€ per participant in the individual level and 10€ in the group-based intervention representing 746€ and 108€ per averted case of diabetes, respectively. The estimated incremental cost-utility ratio was 3243€ per quality-adjusted life-years gained. CONCLUSION The intensive lifestyle intervention delayed the development of diabetes and was efficient in economic analysis.

Abstract
The process of generating evidence-based public health interventions is understood to include steps that define the issue, generate and test solutions in controlled settings, replicate and then disseminate more widely. However, to date models have not considered the types and scale of formative evaluation tasks that are needed to up-scale interventions, from efficacy to population-wide dissemination in the real world. In this paper, we propose that an additional stage of 'translational formative evaluation' is necessary for the translation of effectiveness evidence into wide-scale public health practice. We illustrate the utility of translational formative evaluation, through a case study of the Get Healthy Information and Coaching Service(®) (GHS), a population-based telephone service designed to assist adults change lifestyle-related behaviours. The additional translational formative evaluation steps comprised synthesis of efficacy studies, qualitative research with the wider target audience, environmental analysis and stakeholder consultation. They produced precise recommendations to refine GHS design and implementation. Translational formative evaluation is a necessary intermediate step, following efficacy studies and a precursor to population-wide implementation of public health programmes.

Abstract
OBJECTIVE To determine the comparative effectiveness of three lifestyle intervention modalities in decreasing risk for diabetes. RESEARCH DESIGN AND METHODS Five hundred and fifty-five individuals (86.1% female, 95.1% white, and 55.8% obese) from eight rural communities were screened for BMI ≥25 kg/m(2) and waist circumference >40 inches in men and >35 inches in women. Communities with their eligible participants (n = 493; mean age 51 years, 87.6% female, 94.1% Caucasian) were assigned to four Group Lifestyle Balance (GLB) intervention groups: face to face (FF) (n = 119), DVD (n = 113), internet (INT) (n = 101), and self-selection (SS) (n = 101). SS participants chose the GLB modality. GLB is a comprehensive lifestyle behavior-change program. RESULTS A marked decline was observed in weight after the intervention in all groups (FF -12.5 lbs, P = 0.01; DVD -12.2 lbs, P < 0.0001; INT -13.7 lbs, P < 0.0001; and SS -14 lbs, P < 0.0001). Participants in SS experienced the largest average weight loss. Weight loss was sustained in >90% of participants in each group at 6 months (FF 90.7%, DVD 90.9%, INT 92.1%, and SS 100%). All groups experienced improvements in the proportion of participants with CVD risk factors. The proportion of individuals with CVD risk factors remained steady between 3 and 6 months in all groups and never returned back to baseline. All associations remained after multivariate adjustment. CONCLUSIONS Despite the modality, the GLB intervention was effective at decreasing weight and improving CVD risk factor control. SS and FF participants experienced greater improvements in outcomes compared with other groups, establishing the importance of patient-centered decision making and a support network for successful behavior change.

Abstract
BACKGROUND The effectiveness of lifestyle interventions in reducing diabetes incidence has been well established. Little is known, however, about factors influencing the reach of diabetes prevention programs. This study examines the predictors of enrolment in the Sydney Diabetes Prevention Program (SDPP), a community-based diabetes prevention program conducted in general practice, New South Wales, Australia from 2008-2011. METHODS SDPP was an effectiveness trial. Participating general practitioners (GPs) from three Divisions of General Practice invited individuals aged 50-65 years without known diabetes to complete the Australian Type 2 Diabetes Risk Assessment tool. Individuals at high risk of diabetes were invited to participate in a lifestyle modification program. A multivariate model using generalized estimating equations to control for clustering of enrolment outcomes by GPs was used to examine independent predictors of enrolment in the program. Predictors included age, gender, indigenous status, region of birth, socio-economic status, family history of diabetes, history of high glucose, use of anti-hypertensive medication, smoking status, fruit and vegetable intake, physical activity level and waist measurement. RESULTS Of the 1821 eligible people identified as high risk, one third chose not to enrol in the lifestyle program. In multivariant analysis, physically inactive individuals (OR: 1.48, P = 0.004) and those with a family history of diabetes (OR: 1.67, P = 0.000) and history of high blood glucose levels (OR: 1.48, P = 0.001) were significantly more likely to enrol in the program. However, high risk individuals who smoked (OR: 0.52, P = 0.000), were born in a country with high diabetes risk (OR: 0.52, P = 0.000), were taking blood pressure lowering medications (OR: 0.80, P = 0.040) and consumed little fruit and vegetables (OR: 0.76, P = 0.047) were significantly less likely to take up the program. CONCLUSIONS Targeted strategies are likely to be needed to engage groups such as smokers and high risk ethnic groups. Further research is required to better understand factors influencing enrolment in diabetes prevention programs in the primary health care setting, both at the GP and individual level.

Abstract
The Get Healthy Information and Coaching Service® (GHS), a free government-funded telephone-delivered information and coaching service was launched in February 2009 by the Australian New South Wales state government. It represents the translation of research evidence applied in the real world (T4 or Phase 4 translation), aimed at addressing the modifiable risk factors associated with the overweight and obesity. In controlled settings, it has been established that telephone-based lifestyle counseling programs are efficacious in reducing anthropometric and behavioral risk factors. This article presents the GHS case study as a population-wide intervention and describes the quasi-experimental evaluation framework used to evaluate both the process (statewide implementation) and impact (effectiveness) of the GHS in a real-world environment. It details the data collection, measures, and statistical analysis required in assessing the process of implementation-reach and recruitment, marketing and promotion, service satisfaction, intervention fidelity, and GHS setting up and operations costs-and in assessing the impact of GHS-increasing physical activity, improving dietary practices, and reducing body weight and waist circumference. The comprehensive evaluation framework designed for the GHS provides a method for building effectiveness evidence of a rare translation of efficacy trial evidence into population-wide practice.

Abstract
PURPOSE The purpose of the study was to examine the long-term effect of a Group Lifestyle Balance (GLB) program on weight, impaired fasting glucose, hypertension, and hyperlipidemia in an urban, medically underserved community. METHODS This study was a single-arm prospective intervention study that was designed to test the effectiveness of a community-based GLB intervention. In sum, 638 residents from 11 targeted neighborhoods were screened for body mass index ≥ 25 kg/m(2) and metabolic syndrome. Eligible individuals took part in a 12-week GLB intervention (n = 105) that addressed weight loss and physical activity. Subjects were followed for 24 months. RESULTS The probability of being at risk for diabetes and cardiovascular disease was significantly reduced by 25.7% over the long-term follow-up. Of the participants who lost at least 5% of their body weight following the intervention, 52.6% maintained the 5% weight loss at their last follow-up time, weighing about 20 lb less than they did at baseline. CONCLUSION Risk reduction and weight loss maintenance are possible following a GLB intervention and have substantial potential for future public health impact.

Abstract
OBJECTIVE To evaluate current risk models and scores for type 2 diabetes and inform selection and implementation of these in practice. DESIGN Systematic review using standard (quantitative) and realist (mainly qualitative) methodology. Inclusion criteria Papers in any language describing the development or external validation, or both, of models and scores to predict the risk of an adult developing type 2 diabetes. DATA SOURCES Medline, PreMedline, Embase, and Cochrane databases were searched. Included studies were citation tracked in Google Scholar to identify follow-on studies of usability or impact. DATA EXTRACTION Data were extracted on statistical properties of models, details of internal or external validation, and use of risk scores beyond the studies that developed them. Quantitative data were tabulated to compare model components and statistical properties. Qualitative data were analysed thematically to identify mechanisms by which use of the risk model or score might improve patient outcomes. RESULTS 8864 titles were scanned, 115 full text papers considered, and 43 papers included in the final sample. These described the prospective development or validation, or both, of 145 risk prediction models and scores, 94 of which were studied in detail here. They had been tested on 6.88 million participants followed for up to 28 years. Heterogeneity of primary studies precluded meta-analysis. Some but not all risk models or scores had robust statistical properties (for example, good discrimination and calibration) and had been externally validated on a different population. Genetic markers added nothing to models over clinical and sociodemographic factors. Most authors described their score as "simple" or "easily implemented," although few were specific about the intended users and under what circumstances. Ten mechanisms were identified by which measuring diabetes risk might improve outcomes. Follow-on studies that applied a risk score as part of an intervention aimed at reducing actual risk in people were sparse. CONCLUSION Much work has been done to develop diabetes risk models and scores, but most are rarely used because they require tests not routinely available or they were developed without a specific user or clear use in mind. Encouragingly, recent research has begun to tackle usability and the impact of diabetes risk scores. Two promising areas for further research are interventions that prompt lay people to check their own diabetes risk and use of risk scores on population datasets to identify high risk "hotspots" for targeted public health interventions.

Rationale and design of the PREDICE project: cost-effectiveness of type 2 diabetes prevention among high-risk Spanish individuals following lifestyle intervention in real-life primary care setting. BMC Public Health 2011; 11:623. [PMID: 21831332 PMCID: PMC3199598 DOI: 10.1186/1471-2458-11-623] [Citation(s) in RCA: 11] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2011] [Accepted: 08/04/2011] [Indexed: 01/08/2023] Open
Abstract
Background Type 2 diabetes is an important preventable disease and a growing public health problem. Based on information provided by clinical trials, we know that Type 2 diabetes can be prevented or delayed by lifestyle intervention. In view of translating the findings of diabetes prevention research into real-life it is necessary to carry out community-based evaluations so as to learn about the feasibility and effectiveness of locally designed and implemented programmes. The aim of this project was to assess the effectiveness of an active real-life primary care strategy in high-risk individuals for developing diabetes, and then evaluate its efficiency. Methods/Design Cost-Effectiveness analysis of the DE-PLAN (Diabetes in Europe - Prevention using Lifestyle, physical Activity and Nutritional intervention) project when applied to a Mediterranean population in Catalonia (DE-PLAN-CAT). Multicenter, longitudinal cohort assessment (4 years) conducted in 18 primary health-care centres (Catalan Health Institute). Individuals without diabetes aged 45-75 years were screened using the Finnish Diabetes Risk Score - FINDRISC - questionnaire and a 2-h oral glucose tolerance test. All high risk tested individuals were invited to participate in either a usual care intervention (information on diet and cardiovascular health without individualized programme), or the intensive DE-PLAN educational program (individualized or group) periodically reinforced. Oral glucose tolerance test was repeated yearly to determine diabetes incidence. Besides measuring the accumulated incidence of diabetes, information was collected on economic impact of the interventions in both cohorts (using direct and indirect cost questionnaires) and information on utility measures (Quality Adjusted Life Years). A cost-utility and a cost-effectiveness analysis will be performed and data will be modelled to predict long-term cost-effectiveness. Discussion The project was intended to evidence that a substantial reduction in Type 2 diabetes incidence can be obtained at a reasonable cost-effectiveness ratio in real-life primary health care setting by an intensive lifestyle intervention. As far as we know, the DE-PLAN-CAT/PREDICE project represents the first assessment of long-term effectiveness and cost-effectiveness of a public healthcare strategy to prevent diabetes within a European primary care setting.

Abstract
The process of atherosclerosis may begin in youth and continue for decades, leading to both nonfatal and fatal cardiovascular events, including myocardial infarction, stroke, and sudden death. With primordial and primary prevention, cardiovascular disease is largely preventable. Clinical trial evidence has shown convincingly that pharmacological treatment of risk factors can prevent events. The data are less definitive but also highly suggestive that appropriate public policy and lifestyle interventions aimed at eliminating tobacco use, limiting salt consumption, encouraging physical exercise, and improving diet can prevent events. There has been concern about whether efforts aimed at primordial and primary prevention provide value (ie, whether such interventions are worth what we pay for them). Although questions about the value of therapeutics for acute disease may be addressed by cost-effectiveness analysis, the long time frames involved in evaluating preventive interventions make cost-effectiveness analysis difficult and necessarily flawed. Nonetheless, cost-effectiveness analyses reviewed in this policy statement largely suggest that public policy, community efforts, and pharmacological intervention are all likely to be cost-effective and often cost saving compared with common benchmarks. The high direct medical care and indirect costs of cardiovascular disease-approaching $450 billion a year in 2010 and projected to rise to over $1 trillion a year by 2030-make this a critical medical and societal issue. Prevention of cardiovascular disease will also provide great value in developing a healthier, more productive society.

Abstract
The prevalence of type 2 diabetes is increasing rapidly worldwide. Much of this increase in type 2 diabetes epidemic is related to the increase in obesity. There is now firm evidence from randomised trials that type 2 diabetes is preventable by lifestyle modification influencing diet, physical activity and obesity. This prevention effect is sustainable for many years after cessation of active intervention. The slow progression in the development and implementation of population-based strategies in the prevention of obesity and its most common and serious co-morbidity, type 2 diabetes, is of great concern. We summarise published implementation programmes and describe briefly the activities carried out in Finland. In the Finnish implementation programme for the prevention of type 2 diabetes (FIN-D2D), it was found that it is possible to prevent type 2 diabetes "in real life" in the primary health-care settings. We point out that innovative strategic guidelines and their proper implementation are needed to prevent the diabetes epidemic. Among the different tools, also taxation and other regulation to promote healthy food selection and good interaction with the media should be considered.
