Cost-effectiveness of proactive health support-telephone-based self-management support compared with standard care for persons at risk of hospital admission.

BACKGROUND: A small share of patients account for a large proportion of costs to the healthcare system in Denmark as in many Western countries. A telephone-based self-management support, proactive health support (PaHS), was suggested for prevention of hospitalisations for persons at risk of hospital admission. These persons have chronic diseases, unplanned hospitalisations and age ≥ 65 years. However, evidence is limited on whether this type of intervention is cost-effective. AIM: The aim of this study was to assess the incremental cost-utility ratio (ICER) of PaHS, compared with standard care. METHODS: The economic evaluation was nested within a randomised controlled trial, and was based on a health system perspective, with follow-up and time horizon of 12 months. We measured incremental costs per quality-adjusted life years (QALY) gained. Total average costs per patient included PaHS programme costs, and costs in hospitals, primary care and municipalities. We analysed differences by generalised linear models with Gamma distribution for costs and mixed models for QALY. RESULTS: We analysed data on 6,139 patients, where 3,041 received PaHS and 3,098 received usual care. We found no difference in healthcare costs, and programme costs were on average €1,762 per patient, providing incremental costs of €2,075. Incremental effects on QALY were 0.007, resulting in an ICER of €296,389 per QALY gained. CONCLUSION: We found no evidence of PaHS being cost-effective in this study, but the results will be used to identify new ways to organise similar interventions and identify patients with the objective to reduce health system costs per patient.

An updated validation of the Dietary Quality Score: associations with risk factors for cardiometabolic diseases in a Danish population.

PURPOSE: This study assessed the validity of the Dietary Quality Score (DQS) and investigated the association between the DQS and risk factors for cardiometabolic diseases. METHODS: The DQS was calculated based on an updated 23-item FFQ and validated against a 376-item FFQ. A sub-sample of 450 men and women aged 18-73 years, from the Danish Diet, Cancer and Health-Next generations (DCH-NG) cohort, completed the updated 23-item FFQ. We investigated the associations between the DQS and risk factors for cardiometabolic diseases (lipids, haemoglobin A1c (HbA1c), high-sensitive C-reactive protein (hs-CRP), blood pressure (BP), waist circumference (WC), visceral and total fat mass) using linear regression models. RESULTS: A high DQS, i.e. healthy dietary habits, was significantly associated with a higher intake of fruits, vegetables, fish, fibre, several vitamins and minerals and a lower intake of saturated fat. Moreover, a high DQS was significantly associated with lower levels of LDL cholesterol (P = 0.0133), Hs-CRP (P = 0.0449), WC (P = 0.0161), visceral fat (P = 0.0003), total fat mass (P = 0.0106) and total fat percentage (P = 0.0030) and significantly associated with a higher HDL cholesterol (P = 0.0379) level, when adjusting for education, smoking habits and physical activity. There was no association with total cholesterol, triglycerides, HbA1c, BP and BMI. CONCLUSION: The DQS, based on the updated 23-item FFQ, is a valid tool to classify individuals into groups with low, average and high dietary quality in the Danish population. Furthermore, a high DQS is significantly associated with lower levels of several risk factors for cardiometabolic diseases.

Involving supermarkets in health promotion interventions in the Danish Project SoL. A practice-oriented qualitative study on the engagement of supermarket staff and managers.

BACKGROUND: Supermarkets have been suggested as relevant settings for environmental and educational initiatives encouraging healthier shopping and eating decisions, but in the literature, limited attention has been paid to the context, perspectives, and everyday practices of supermarket staff. The aim of this study was to examine the engagement of supermarket staff in a health promotion project from a practice-oriented perspective. METHODS: The study was based on qualitative data collected in the supermarket setting of Project SoL; a community-based health promotion project in Denmark. We conducted 26 in-depth interviews with store managers and other key staff members in seven participating supermarkets. In addition, we collected data on planning, implementation, and perceptions of supermarket staff of in-store interventions and other project-related activities. These field data included short telephone interviews, observational notes, photos, and audiotapes of meetings. Data were analysed from the perspective of practice theory. RESULTS: Although supermarket staff found community-based health promotion meaningful to engage in, the study observed that their engagement was challenged by a business mindset, practical routines and structural requirements favouring sales promotion over health promotion. Nevertheless, there were also examples of how health promotion activities and ways of thinking were successfully incorporated in everyday staff practices during and after Project SoL. CONCLUSIONS: Our findings point to both potentials and challenges for using supermarkets as settings for health promotion. The voluntary engagement of supermarket staff in community-based health projects cannot stand alone but should be supplemented by more long-lasting strategies and policies regulating this and other food environments. Context-sensitive and practice-oriented analyses in local food environments could inform such strategies and policies to make sure they target unwanted elements and practices and not just individual behavior.

Three-year follow-up of a multi-component community-driven health promotion intervention in Denmark.

The article presents a follow-up study of a multi-component community-driven health promotion intervention in Denmark. The study examines the perceptions and actions of professional stakeholders 3 years after completion of a 19 months intervention period addressing healthy living, well-being and social engagement among families with young children living in three rural communities on the Danish island of Bornholm. The intervention was implemented within the framework of Project Health and Local Community, also referred to as Project SoL. Qualitative in-depth interviews were conducted with diverse professional stakeholders of the project. They represented local government, public institutions, private enterprises, civil society organizations and local mass media. The interviews addressed the extent to which the project had sustained its influence on professional stakeholders' perceptions and actions following project completion. Efforts were made to understand if persisting influences were value-based and/or manifested as concrete community-driven actions. The study showed that the project had succeeded in sustaining a positive long-term post-intervention influence among informants regarding the values and principles of the project. Despite their sustained motivation and preparedness to continue implementing coordinated community-driven actions this was severely hampered by lack of coordination after project completion. Instead, some of the stakeholders continued developing and implementing actions based on the values and principles of the project within the framework of their own professional networks. The article discusses the structural factors that are required to sustain complex community-driven interventions and the need to reconsider the nature of external support to community development from being project-based to integrated, strategic and long term.

Nurses' perspectives on challenges and facilitators when implementing a self-management support intervention as an everyday healthcare practice: A qualitative study.

AIM: To explore registered nurses' perspectives on challenges and facilitators to implementing a telephone-based self-management support (SMS) intervention (Proactive Health Support) as an everyday healthcare practice, during the early stages of implementation. DESIGN: Data were collected using a qualitative research design involving focus-group interviews and participant observations. METHODS: We conducted participant observation following nine nurses and four focus group interviews with 14 nurses. Data were analysed using thematic analyses. RESULTS: Proactive Health Support was implemented in units organized independently of the existing organizational units within healthcare services. This independent organization, along with the intervention's generic (non-disease specific) design, empowered nurses to become autonomous practitioners capable of prioritizing the operationalization of SMS as an everyday healthcare practice. However, unlearning already embedded medical practices and establishing new nursing roles necessary to accommodate the intervention in practice was experienced a challenge. Education and supervision were identified as valuable tools for successful implementation. CONCLUSION: Our study highlights the significance of organizational context and autonomy in successful SMS implementation. Balancing external factors like organizational context, priority and time is vital, but navigating the internal shift in professional practice is equally crucial. Role transition processes can constitute challenges demanding accommodation. IMPLICATIONS FOR THE PROFESSION: From a nursing perspective, this study highlights that practising SMS requires substantial training and education. Generic SMS interventions can introduce higher levels of contingency due to their versatile nature. Thus, equipping nurses with competencies that enable them to navigate this unpredictability flexibly is crucial. IMPACT: Policymakers and administrators should allocate resources and support implementation processes in ways that accommodate both internal and external conditions to facilitate nurses in delivering effective SMS. REPORTING METHOD: This study adheres to the SRQR guideline. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Proactive Health Support: a randomised controlled trial of telephone-based self-management support for persons at risk of hospital admission.

BACKGROUND: Persons with frequent hospital admissions have a disease burden that may exceed their self-management skills. The evidence base of telephone-based interventions to support self-management is poor with mixed results. The aim of this study is to evaluate the effect of Proactive Health Support (PaHS): telephone-based self-management support for persons with risk of hospitalizations. METHODS: This study is a national randomised controlled trial of PaHS versus usual universal tax-funded healthcare. Participants were persons at risk of emergency hospital admissions. The intervention began with a physical start-up session followed by telephone sessions of self-management support. The two co-primary outcomes were Health-Related Quality of Life (HRQoL) (Mental Health Component Summary Score of SF36v2) analysed with mixed models and hospital admissions analysed with Poisson regression at 6 months. Secondary outcomes were at 3- and 12-month follow-up and disease subgroup analyses. RESULTS: During the study period, 6,402 persons were randomised (3,190 intervention, 3,212 control). HRQoL was significantly improved at 6 months (Est. 1.4992, P = <0.0001) and at 3 and 12 months on all 10 scales. There was no overall effect on hospital admissions at 6 months with an adjusted estimate of 0.0074 (P = 0.8691). Persons with diabetes had significant improvement of HRQoL and reduced hospital admissions. CONCLUSIONS: The PaHS intervention improved HRQoL for all participants and reduced hospital admissions for persons with diabetes only.

Validation of retail food outlet data from a Danish government inspection database.

BACKGROUND: Globally, unhealthy diet is one of the leading global risks to health, thus it is central to consider aspects of the food environment that are modifiable and may enable healthy eating. Food retail data can be used to present and facilitate analyses of food environments that in turn may direct strategies towards improving dietary patterns among populations. Though food retail data are available in many countries, their completeness and accuracy differ. METHODS: We applied a systematically name-based procedure combined with a manual procedure on Danish administrative food retailer data (i.e. the Smiley register) to identify, locate and classify food outlets. Food outlets were classified into the most commonly used classifications (i.e. fast food, restaurants, convenience stores, supermarkets, fruit and vegetable stores and miscellaneous) each divided into three commonly used definitions; narrow, moderate and broad. Classifications were based on branch code, name, and/or information on the internal and external appearance of the food outlet. From ground-truthing we validated the information in the register for its sensitivity and positive predictive value. RESULTS: In 361 randomly selected areas of the Capital region of Denmark we identified a total of 1887 food outlets compared with 1861 identified in the register. We obtained a sensitivity of 0.75 and a positive predictive value of 0.76. Across classifications, the positive predictive values varied with highest values for the moderate and broad definitions of fast food, convenience stores and supermarkets (ranging from 0.89 to 0.97). CONCLUSION: Information from the Smiley Register is considered to be representative to the Danish food environment and may be used for future research.

Soluble urokinase plasminogen activator receptor is linearly associated with dietary quality and predicts mortality.

Chronic inflammation is associated with disease risk and mortality in the general population. Soluble urokinase plasminogen activator receptor (suPAR) is a stable marker of chronic inflammation, and a higher serum-concentration of suPAR is found in individuals with an unhealthy lifestyle such as smoking. This article investigates the association between suPAR and dietary quality measured with the dietary quality score (DQS). The DQS is an index of the overall quality of an individual's dietary habits assessed through a self-administered FFQ. Furthermore, this article investigates the association of both suPAR and the DQS with CVD risk and mortality in the general Danish population. We analysed 5347 individuals aged 30-60 years from the Danish Inter99 study cohort. Multiple linear regression analyses showed a linear inverse association between the DQS and suPAR (P=0·0005). Cox regression analyses showed an 18 (95 % CI 9, 26) % increase in the risk of death from any cause with each 1 ng/ml increase in suPAR. We found no significant association between the DQS and the mortality (hazard ratio: 1·16, 95 % CI 0·79, 1·69). All analyses were adjusted for demographics and lifestyle factors. The association between the DQS and suPAR on the one hand and suPAR and mortality on the other supports the argument that low dietary quality may constitute a health risk through its influence on chronic inflammation. Future research should examine whether suPAR is modifiable through changes in dietary habits.

The effect of introducing a free breakfast club on eating habits among students at vocational schools.

BACKGROUND: Unhealthy eating habits are a major problem among adolescents. The objective of the study was to assess the effect of a free breakfast club intervention on dietary habits among students at vocational schools. METHODS: The study included students (n = 318) from four vocational schools in Denmark. Food frequency questionnaires were used to measure eating habits at baseline, first, and second follow-up, after 7 and 14 weeks respectively, in a clustered randomized controlled intervention of four months. The effect of the intervention was evaluated through self-reported frequencies of breakfast intake, intake of whole grain products for breakfast and intake of unhealthy snacking in the morning. The outcome measures were daily breakfast intake (yes/no), daily intake of whole grain for breakfast (yes/no), and unhealthy snacking on school day mornings (yes/no). RESULTS: The proportion of students who had breakfast every school day increased significantly in the intervention schools from baseline to the first follow-up compared to the control group (OR: 3.77; P = 0.0149). The effect was attenuated at the second follow-up. The intake of whole grain products for breakfast increased significantly more among students in intervention schools compared to students in control schools both at first (OR: 4.13; P = 0.0079) and second follow-up (OR: 3.27; P = 0.0317). No significant change in unhealthy snacking was found. CONCLUSION: Provision of free breakfast at vocational schools can improve the dietary quality of breakfast and decrease breakfast skipping. However, the sustainability of the intervention is a critical issue that needs to be further studied and addressed. TRIAL REGISTRATION: ISRCTN11265280 .

Children as visionary change agents in Danish school health promotion.

This paper describes children's perceptions and visions for a healthier social and physical environment in the setting of a primary school on the Danish island of Bornholm. Guided by an everyday-life perspective and applying participatory action research methods including social imagination and visual techniques within the framework of future creating workshops, the study engaged 50 children aged 6-9 years in creative processes of identifying health-related problem areas and solutions in their school setting. The study observed that the children were very capable of articulating their thoughts, ideas and visions for a better and healthier school environment. Identified problem areas and solutions differed widely and represented a broad perspective of health including social, physical, environmental and emotional aspects. The paper discusses advantages and challenges of involving children in decision-making processes and concludes that children are visionary and creative agents of change in health promotion projects provided that applied participatory methods are appealing to the children.

Population-based studies of relationships between dietary acidity load, insulin resistance and incident diabetes in Danes.

BACKGROUND: It has been suggested that the acidity of the diet may be related to increased risk of type 2 diabetes. To investigate this hypothesis, we tested if the acidity of the diet, measured as the Potential Renal Acid Load (PRAL) score, was associated with incident diabetes and diabetes-related intermediary traits. METHODS: A total of 54,651 individuals from the Danish Diet, Cancer and Health (DCH) cohort were included in the prospective cox regression analyses of incident diabetes over a 15 years follow-up period. Moreover, 5724 Danish individuals with baseline data from the Inter99 cohort were included in the cross sectional, multivariate and logistic regression analyses of measures of insulin sensitivity, insulin release and glucose tolerance status derived from an oral glucose tolerance test (OGTT). RESULTS: In the DCH cohort a trend analysis showed that quintiles of PRAL score were, after multifactorial adjustment, associated with a higher incidence of diabetes (ptrend = 6 × 10- 7). HR for incident diabetes was 1.24 (1.14; 1.35) (p = 7 × 10- 7) between first and fifth PRAL score quintile. In Inter99 higher PRAL score associated with insulin resistance as estimated by lower BIGTT-Si (an OGTT-derived index of insulin sensitivity) (p = 4 × 10- 7) and Matsuda index of insulin sensitivity (p = 2 × 10- 5) as well as higher HOMA-IR (p = 0.001). No association was observed for measures of insulin release, but higher PRAL score was associated with lower OGTT-based disposition index. CONCLUSIONS: A high dietary acidity load is associated with a higher risk of diabetes among middle-aged Danes. Although adjustment for BMI attenuated the effect sizes the association remained significant. The increased risk of diabetes may be related to our finding that a high dietary acidity load associates with impaired insulin sensitivity.

Alcohol consumption and its interaction with adiposity-associated genetic variants in relation to subsequent changes in waist circumference and body weight.

BACKGROUND: Studies have suggested a link between alcohol intake and adiposity. However, results from longitudinal studies have been inconsistent, and a possible interaction with genetic predisposition to adiposity measures has often not been taken into account. OBJECTIVE: To examine the association between alcohol intake recorded at baseline and subsequent annual changes in body weight (∆BW), waist circumference (ΔWC) and WC adjusted for BMI (ΔWCBMI), and to test for interaction with genetic predisposition scores based on single nucleotide polymorphisms (SNPs) associated with various forms of adiposity. METHOD: This study included a total of 7028 adult men and women from MONICA, the Diet, Cancer and Health cohort (DCH), and the Inter99 studies. We combined 50 adiposity-associated SNPs into four scores indicating genetic predisposition to BMI, WC, WHRBMI and all three traits combined. Linear regression was used to examine the association of alcohol intake (drinks of 12 g (g) alcohol/day) with ΔBW, ΔWC, and ΔWCBMI, and to examine possible interactions with SNP-scores. Results from the analyses of the individual cohorts were combined in meta-analyses. RESULTS: Each additional drink/day was associated with a ΔBW/year of -18.0 g (95% confidence interval (CI): -33.4, -2.6, P = 0.02) and a ΔWC of -0.3 mm/year (-0.5, -0.0, P = 0.03). In analyses of women only, alcohol intake was associated with a higher ΔWCBMI of 0.5 mm/year (0.2, 0.9, P = 0.002) per drink/day. Overall, we found no statistically significant interactions between the four SNP-scores and alcohol intake in relation to changes in adiposity measures. However in analyses of women separately, we found interaction between the complete score of all 50 SNPs and alcohol intake in relation to ΔBW (P for interaction = 0.03). No significant interaction was observed among the men. CONCLUSION: Alcohol intake was associated with a decrease in BW and WC among men and women, and an increase in WCBMI among women only. We found no strong indication that these associations depend on a genetic predisposition to adiposity.

Relative validity and reproducibility of a parent-administered semi-quantitative FFQ for assessing food intake in Danish children aged 3-9 years.

OBJECTIVE: To assess the relative validity and reproducibility of the semi-quantitative FFQ (SFFQ) applied in the evaluation of a community intervention study, SoL-Bornholm, for estimating food intakes. DESIGN: The reference measure was a 4 d estimated food record. The SFFQ was completed two times separated by a 1-month period in order to test reproducibility. SETTING: The Capital Region and the Regional Municipality of Bornholm, Denmark. SUBJECTS: A total of fifty-four children aged 3-9 years were enrolled in the study. RESULTS: In terms of validity, the SFFQ generally overestimated intakes compared with the food records, especially for vegetables. For most intakes, the mean difference increased with increasing intake. Gross misclassification was on average higher for energy and nutrients (17%) than for foods (8%). Spearman correlation coefficients were significant for twelve out of fourteen intakes, ranging from 0·29 to 0·63 for foods and from 0·12 to 0·48 for energy and nutrients. Comparing the repeated SFFQ administrations, the intakes of the first SFFQ were slightly higher than those of the second SFFQ. Gross misclassification was low for most intakes; on average 6% for foods and 8% for energy and nutrients. Intra-class correlations were significant for all intakes, ranging from 0·30 to 0·82 for foods and from 0·46 to 0·81 for energy and nutrients. CONCLUSIONS: The results indicate that the SFFQ gives reproducible estimates. The relative validity of the SFFQ was low to moderate for most intakes but comparable to other studies among children.

Substituting sugar confectionery with fruit and healthy snacks at checkout - a win-win strategy for consumers and food stores? a study on consumer attitudes and sales effects of a healthy supermarket intervention.

BACKGROUND: The widespread use of in-store marketing strategies to induce unhealthy impulsive purchases has implications for shopping experience, food choice and possibly adverse health outcomes. The aim of this study was to examine consumer attitudes and evaluate sales effects of a healthy checkout supermarket intervention. The study was part of Project Sundhed & Lokalsamfund (Project SoL); a Danish participatory community-based health promotion intervention. METHODS: Consumer attitudes towards unhealthy snack exposure in supermarkets were examined in a qualitative pre-intervention study (29 short in-store interviews, 11 semi-structured interviews and three focus group interviews). Findings were presented to food retailers and informed the decision to test a healthy checkout intervention. Sugar confectionery at one checkout counter was substituted with fruit and healthy snacking items in four stores for 4 weeks. The intervention was evaluated by 48 short exit interviews on consumer perceptions of the intervention and by linear mixed model analyses of supermarket sales data from the intervention area and a matched control area. RESULTS: The qualitative pre-intervention study identified consumer concern and annoyance with placement and promotion of unhealthy snacks in local stores. Store managers were willing to respond to local consumer concern and a healthy checkout intervention was therefore implemented. Exit interviews found positive attitudes towards the intervention, while intervention awareness was modest. Most participants believed that the intervention could help other consumers make healthier choices, while fewer expected to be influenced by the intervention themselves. Statistical analyses suggested an intervention effect on sales of carrot snack packs when compared with sales before the intervention in Bornholm control stores (P < 0.05). No significant intervention effect on sales of other intervention items or sugar confectionery was found. CONCLUSIONS: The present study finds that the healthy checkout intervention was positively evaluated by consumers and provided a 'responsible' branding opportunity for supermarkets, thus representing a win-win strategy for store managers and consumers in the short term. However, the intervention was too modest to draw conclusions on long-term sales and health implications of this initiative. More research is needed to assess whether retailer-researcher collaborations on health promotion can be a winning strategy for public health.

The association between accessibility of local convenience stores and unhealthy diet.

BACKGROUND: High accessibility of unhealthy food stores may contribute to a poor dietary quality. Research on the link between neighbourhood food environment and consumption is limited, especially in a European context. The objective of this study was to examine the relationship between convenience stores (CS) and dietary quality within the Capital Region of Denmark. METHOD: Cross-sectional study of the geographic food environment in the Capital Region of Denmark based on 47 623 subjects (age 16+ years) with complete information on retail food environment and dietary quality. A categorization procedure to identify CS from a government list of inspected food stores (the Smiley register) was developed. Using GIS network analyses, density of CS within 0.25 km and 0.5 km network buffers from residency was calculated for participants in metropolitan and non-metropolitan areas, respectively. Information on dietary intake and confounders is derived from a questionnaire survey. Multi-level analyses were performed, adjusting for age, sex, individual socio-economic factors and area socio-economic status. RESULTS: In the non-metropolitan population, the odds of having an unhealthy diet increased significantly (P < 0.0001) with increased density of CS. Compared to individuals who did not have a CS within 0.5 km from their home, the odds ratios were 1.20 (95% CI: 1.09-1.33) and 1.37 (95% CI: 1.19-1.57) for individuals having 1 or ≥2 CS, respectively. In the fully adjusted model, the overall association remained significant (P = 0.015) and odds ratios diminished to 1.14 (1.02-1.27) and 1.18 (1.01-1.38). CONCLUSION: High accessibility of CS in neighbourhoods is associated with less healthy dietary habits among residents.

The long-term effect of screening and lifestyle counseling on changes in physical activity and diet: the Inter99 Study - a randomized controlled trial.

BACKGROUND: Multi-factorial intervention studies have been found to be successful in the initiation of lifestyle changes. However, little is known about the longer-term maintenance of health behavior improvements. The purpose of this study was to investigate whether improvements in physical activity and dietary habits achieved in a population-based multi-factorial lifestyle intervention of five years duration were maintained five years after intervention activities have ended. METHODS: The study was a population-based randomized controlled trial, Inter99 (1999-2006), Copenhagen, Denmark. Over five years, all participants in the intervention group (n = 6,091) received individual lifestyle counseling; participants at high risk of ischemic heart disease - according to pre-specified criteria - were also offered group-based counseling. The control group (n = 3,324) was followed by questionnaires. Both groups were followed one, three, five, and ten years after baseline. Changes in physical activity and dietary habits (intake of vegetables, fruit, fish, and saturated fat) during and after the intervention were investigated using random-coefficient models. RESULTS: Five years after the intervention, women in the intervention group reported greater improvements in the intake of fruit (M Δ = 90.2 g/week, p = 0.041) and less intake of saturated fat (OR = 0.30, 95% CI: 0.17-0.54) than the control group. Men in the intervention group reported greater improvements in physical activity (M Δ = 19.6 min/week, p = 0.003) and less intake of saturated fat (OR = 0.31, 95% CI: 0.17-0.56) than the control group. Improvements in the intake of vegetables and fish achieved during the intervention were not maintained in the longer-term. CONCLUSIONS: Screening and lifestyle counseling had sustained effects on physical activity and dietary habits five years after its discontinuation. The patterns of long-term changes in lifestyle differed across behaviors and between men and women. TRIAL REGISTRATION: ClinicalTrials.gov ( NCT00289237 ).

The Danish fat tax-Effects on consumption patterns and risk of ischaemic heart disease.

OBJECTIVE: To examine the effects on consumption and risk of ischemic heart disease (IHD) of the Danish fat tax, effective from October 2011 to January 2013. METHODS: We used comprehensive retail outlet data on the sale of twelve foodstuff categories targeted by the fat tax. Data covered January 2010 to July 2013. IHD risk was assessed by modelling first the effect of changes in intake of monounsaturated, polyunsaturated and saturated fat and dietary cholesterol on serum cholesterol and subsequently modelling the resulting changes in risk of IHD using two different methods. RESULTS: The total sale of the included foodstuffs decreased by 0.9%. The fat tax was associated with marginal changes in population risk of IHD. One estimate suggests an increased population risk of IHD by 0.2% and the other estimate suggests that the risk of IHD decreased by 0.3%. CONCLUSIONS: The Danish fat tax had a marginal effect on population consumption of fat and risk of IHD. Fat taxes have to be carefully designed to prevent possible adverse effects from outweighing its beneficial effects on health outcomes. Policymakers must therefore be more ambitious in relation to food taxes, e.g. by implementing more comprehensive tax-subsidy schemes.

The development in body mass index, overweight and obesity in three regions in Denmark.

BACKGROUND: The prevalence of overweight and obesity has increased markedly the past decades. However, recent studies have indicated that the development differ between different socio-economic groups and different geographic regions. The aim of this study was to assess the development in prevalence of overweight and obesity from 2006/2007 to 2010 by age, gender, socio-economic factors and geographical regions. METHODS: Two cross-sectional surveys in three regions in Denmark (The Capital Region of Denmark, The Central Denmark Region and The North Denmark Region) were performed in 2006/2007 and 2010. A random sample of citizens aged more than or equal to 25 years was invited to participate. The overall response rate was 57.5% (n = 177 076). Data from questionnaire and central registers were included. RESULTS: In 2006/2007, the prevalence of overweight, including obesity, was 54.3% and 36.8% among men and women, respectively. Of the overweight men 12.8% were obese and 11.8% women were obese. The prevalence was highest in the Northern region and among those who were older, had short education, was outside labour market, had low income and residents in rural areas. In 2010, the prevalence of overweight had increased to 56.3% and 39.6% in men and women, respectively (P < 0.0001). However, overweight increased the most in the Northern Region whereas no significant increase in body mass index was found among men in the Capital Region. Among women prevalence of overweight increased but not in those retired or above 60 years, and with high income. CONCLUSION: The prevalence of overweight and obesity was high and increased. The development, however, was heterogenic.

Revitalizing the setting approach - supersettings for sustainable impact in community health promotion.

BACKGROUND: The concept of health promotion rests on aspirations aiming at enabling people to increase control over and improve their health. Health promotion action is facilitated in settings such as schools, homes and work places. As a contribution to the promotion of healthy lifestyles, we have further developed the setting approach in an effort to harmonise it with contemporary realities (and complexities) of health promotion and public health action. The paper introduces a modified concept, the supersetting approach, which builds on the optimised use of diverse and valuable resources embedded in local community settings and on the strengths of social interaction and local ownership as drivers of change processes. Interventions based on a supersetting approach are first and foremost characterised by being integrated, but also participatory, empowering, context-sensitive and knowledge-based. Based on a presentation of "Health and Local Community", a supersetting initiative addressing the prevention of lifestyle diseases in a Danish municipality, the paper discusses the potentials and challenges of supporting local community interventions using the supersetting approach. DISCUSSION: The supersetting approach is a further development of the setting approach in which the significance of integrated and coordinated actions together with a participatory approach are emphasised and important principles are specified, all of which contribute to the attainment of synergistic effects and sustainable impact of supersetting initiatives. The supersetting approach is an ecological approach, which places the individual in a social, environmental and cultural context, and calls for a holistic perspective to change potentials and developmental processes with a starting point in the circumstances of people's everyday life. The supersetting approach argues for optimised effectiveness of health promotion action through integrated efforts and long-lasting partnerships involving a diverse range of actors in public institutions, private enterprises, non-governmental organisations and civil society. SUMMARY: The supersetting approach is a relevant and useful conceptual framework for developing intervention-based initiatives for sustainable impact in community health promotion. It strives to attain synergistic effects from activities that are carried out in multiple settings in a coordinated manner. The supersetting approach is based on ecological and whole-systems thinking, and stipulates important principles and values of integration, participation, empowerment, context and knowledge-based development.

Dietary ascorbic acid and subsequent change in body weight and waist circumference: associations may depend on genetic predisposition to obesity--a prospective study of three independent cohorts.

BACKGROUND: Cross-sectional data suggests that a low level of plasma ascorbic acid positively associates with both Body Mass Index (BMI) and Waist Circumference (WC). This leads to questions about a possible relationship between dietary intake of ascorbic acid and subsequent changes in anthropometry, and whether such associations may depend on genetic predisposition to obesity. Hence, we examined whether dietary ascorbic acid, possibly in interaction with the genetic predisposition to a high BMI, WC or waist-hip ratio adjusted for BMI (WHR), associates with subsequent annual changes in weight (∆BW) and waist circumference (∆WC). METHODS: A total of 7,569 participants' from MONICA, the Diet Cancer and Health study and the INTER99 study were included in the study. We combined 50 obesity associated single nucleotide polymorphisms (SNPs) in four genetic scores: a score of all SNPs and a score for each of the traits (BMI, WC and WHR) with which the SNPs associate. Linear regression was used to examine the association between ascorbic acid intake and ΔBW or ΔWC. SNP-score × ascorbic acid interactions were examined by adding product terms to the models. RESULTS: We found no significant associations between dietary ascorbic acid and ∆BW or ∆WC. Regarding SNP-score × ascorbic acid interactions, each additional risk allele of the 14 WHR associated SNPs associated with a ∆WC of 0.039 cm/year (P = 0.02, 95% CI: 0.005 to 0.073) per 100 mg/day higher ascorbic acid intake. However, the association to ∆WC only remained borderline significant after adjustment for ∆BW. CONCLUSION: In general, our study does not support an association between dietary ascorbic acid and ∆BW or ∆WC, but a diet with a high content of ascorbic acid may be weakly associated to higher WC gain among people who are genetically predisposed to a high WHR. However, given the quite limited association any public health relevance is questionable.
