Flawed conclusions on the Västerbotten Intervention Program by San Sebastian et .al. BMC Public Health 2019; 19:1095. [PMID: 31409308 PMCID: PMC6693255 DOI: 10.1186/s12889-019-7444-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Accepted: 08/06/2019] [Indexed: 11/24/2022] Open
Abstract
An evaluation of Västerbotten Intervention Programme (VIP) was recently conducted by San Sebastian et al. (BMC Public Health 19:202, 2019). Evaluation of health care interventions of this kind require 1) an understanding of both the design and the nature of the intervention, 2) correct definition of the target population, and 3) careful choice of the appropriate evaluation method. In this correspondence, we review the approach used by San Sebastian et al. as relates to these three criteria. Within this framework, we suggest important explanations for why the conclusions drawn by these authors contradict a large body of research on the effectiveness of the VIP.

Abstract
AIM Effective evidence-based interventions have an important role in obesity prevention. Our aim was to present a qualitative synthesis of setting-based health promotion interventions on obesity, from Nordic countries and the Netherlands. METHODS A systematic review of the literature was completed for studies in the community, schools, and worksite, with BMI as an outcome. A descriptive analysis was completed for all full-text articles meeting the inclusion criteria. RESULTS Thirty-three articles were identified: 7 whole of community, 3 worksite, and 23 school-based interventions. The studies were largely quasiexperimental in design (21/33), with follow-up from 4 months to 8 years. The explicit use of theory was not featured in many of the studies (20/33). No consistent direction for BMI change could be identified in the whole of community interventions (2/7 positive, 2/7 negative, and 3/7 no effect) and no effect for worksite (3/3 no effect) or many of the school-based interventions (1/23 negative, 4/23 positive, 15/23 no effect, 1/23 BMI significant increase only for control group and 3/23 no data available). CONCLUSIONS There is a need to prioritise interventions with study designs of high quality, theory, and a participatory approach, for optimal implementation and evaluation of obesity prevention interventions.

Abstract
Objectives: This paper aims to develop and describe a method for combining, comparing, and maximizing the statistical power of two longitudinal studies of risk factors for cardiovascular disease that did not have identical data collection methodologies. Methods: Subjects from a 1986 cross-sectional study (n= 180) were pair-matched with subjects of corresponding gender and age (+ 5 years) from a 1990 cross-sectional study. The methodology is described and results are calculated for various measures of cardiovascular risk or risk factors (e.g. cholesterol, Finnish Risk Score). Results: Box's test of equality and symmetry of covariance matrices gave chi-square values of 223.8 and 710.0 for two cardiovascular risk factors (cholesterol and cardiac risk score, respectively); these values were highly significant (p=0.0001). For the North Karelia Risk Score, repeated measures ANOVA revealed a borderline significant interaction for treatment by time (p=0.054) and a significant interaction for treatment by time by country (p=0.035). These probabilities compared favorably with a randomized blocks model. Conclusions: Creation of a synthetic longitudinal control group resulted in a statistically valid ANOVA model that increased the statistical power of the study.

Abstract
Objectives: There is a need among healthcare providers to acquire more knowledge about small-scale and low budget community intervention programmes. This paper compares risk factor outcomes in Swedish and US intervention programmes for the prevention of cardiovascular disease (CVD). The aim was to explore how different intervention programme profiles affect outcome. Methods: Using a quasi-experimental design, trends in risk factors and estimated CVD risk in two intervention areas (Norsjö, Sweden and Otsego- Schoharie County, New York state) are compared with those in reference areas (Northern Sweden region and Herkimer County, New York state) using serial cross-sectional studies and panel studies. Results: The programmes were able to achieve significant changes in CVD risk factors that the local communities recognized as major concerns: changing eating habits in the Swedish population and reducing smoking in the US population. For the Swedish cross-sectional follow-up study cholesterol reduction was 12%, compared to 5% in the reference population ( p for trend differences < 0.000) . The significantly higher estimated CVD risk (as assessed by risk scores) at baseline in the intervention population was below that of the Swedish reference population after 5 years of intervention. The Swedish panel study provided the same results. In the US, both the serial cross-sectional and panel studies showed a >10% decline in smoking prevalence in the intervention population, while it increased slightly in the reference population. When pooling the serial cross-sectional studies the estimated risk reduction (using the Framingham risk equation) was significantly greater in the intervention populations compared to the reference populations. Conclusions: The overall pattern of risk reduction is consistent and suggests that the two different models of rural county intervention can contribute to significant risk reduction. The Swedish programme had its greatest effect on reduction of serum cholesterol levels whereas the US programme had its greatest effect on smoking prevention and cessation. These outcomes are consistent with programmatic emphases. Socially less privileged groups in these rural areas benefited as much or more from the interventions as those with greater social resources.

Abstract
Background In 1988, a cardiovascular prevention program which combined an individual and a population-based strategy was launched within primary health-care in Sollentuna, a municipality in Stockholm County. The aim of this study was to investigate time trends in the incidence of and mortality from acute myocardial infarction and all-cause mortality in Sollentuna compared with the rest of Stockholm County during a period of two decades following the implementation of a cardiovascular prevention program. Materials and Methods The average population in Sollentuna was 56,589 (49% men) and in Stockholm County (Sollentuna included) 1,795,504 (49% men) during the study period of 1987–2010. Cases of hospitalized acute myocardial infarction and death were obtained for the population of Sollentuna and the rest of Stockholm County using national registries of hospital discharges and deaths. Acute myocardial infarction incidence and mortality were estimated using the average population of Sollentuna and Stockholm in 1987–2010. Results During the observation period, the incidence of acute myocardial infarction decreased more in Sollentuna compared with the rest of Stockholm County in women (-22% vs. -7%; for difference in slope <0.05). There was a trend towards a greater decline in Sollentuna compared to the rest of Stockholm County in the incidence of acute myocardial infarction (in men), acute myocardial mortality, and all-cause mortality but the differences were not significant. Conclusion During a period of steep decline in acute myocardial infarction incidence and mortality in Stockholm County the municipality of Sollentuna showed a stronger trend in women possibly compatible with favorable influence of a cardiovascular prevention program.

Abstract
BACKGROUND This paper uses a life-course approach to explore whether the timing and/or duration of urban (vs rural) exposure was associated with risk factors for NCDs. METHODS A cross-sectional survey was conducted among health care workers in two hospitals in Thailand. Two measures of urbanicity were considered: early-life urban exposure and the proportion of urban life years. We explored four behavioral NCD risk factors, two physiological risk factors and four biological risk factors. RESULTS Both measures of urbanicity were each independently associated with increases in all behavioral and physiological risk factors. For some biological risk factors, people spending their early life in an urban area may be more susceptible to the effect of increasing proportion of urban life years than those growing up in rural areas. CONCLUSION Urbanicity was associated with increases in behavioral and physiological risk factors. However, these associations may not translate directly into increases in biological risk factors. It is likely that these biological risk factors were results of a complex interaction between both long term accumulation of exposure and early life exposures.

Abstract
BACKGROUND Many programmes to detect and prevent cardiovascular disease (CVD) have been performed, but the optimal strategy is not yet clear. AIM To present a systematic review of cardiometabolic screening programmes performed among apparently healthy people (not yet known to have CVD, diabetes, or cardiometabolic risk factors) and mixed populations (apparently healthy people and people diagnosed with risk factor or disease) to define the optimal screening strategy. DESIGN AND SETTING Systematic review of studies performed in primary care in Western countries. METHOD MEDLINE, Embase, and CINAHL databases were searched for studies screening for increased cardiometabolic risk. Exclusion criteria were studies designed to assess prevalence of risk factors without follow-up or treatment; without involving a GP; when fewer than two risk factors were considered as the primary outcome; and studies constrained to ethnic minorities. RESULTS The search strategy yielded 11 445 hits; 26 met the inclusion criteria. Five studies (1995-2012) were conducted in apparently healthy populations: three used a stepwise method. Response rates varied from 24% to 79%. Twenty-one studies (1967-2012) were performed in mixed populations; one used a stepwise method. Response rates varied from 50% to 75%. Prevalence rates could not be compared because of heterogeneity of used thresholds and eligible populations. Observed time trends were a shift from mixed to apparently healthy populations, increasing use of risk scores, and increasing use of stepwise screening methods. CONCLUSION The optimal screening strategy in primary care is likely stepwise, in apparently healthy people, with the use of risk scores. Increasing public awareness and actively involving GPs might facilitate screening efficiency and uptake.

Abstract
A genetic variant within the CHRNA5-CHRNA3-CHRNB4 region (rs1051730), previously associated with smoking quantity, was recently shown to interact with smoking on obesity predisposition. We attempted to replicate this finding in the Gene-Lifestyle Interactions and Complex Traits Involved in Elevated Disease Risk (GLACIER) Study, a prospective cohort study of adults from northern Sweden (n = 16,426). We also investigated whether a similar interaction is apparent between rs1051730 and snus, a type of moist oral tobacco, to determine whether this interaction is driven by factors that cigarettes and snus have in common, such as nicotine. Main effects of smoking, snus, and the rs1051730 variant and pairwise interaction terms (smoking × rs1051730 and snus × rs1051730) were tested in relation to body mass index (BMI; calculated as weight (kg)/height (m)²) through the use of multivariate linear models adjusted for age and sex. Smoking status and BMI were inversely related (β = -0.46 kg/m², standard error (SE) = 0.08; P < 0.0001). Snus use and BMI were positively related (β = 0.35 kg/m², SE = 0.12; P = 0.003). The rs1051730 variant was not significantly associated with smoking status or snus use (P > 0.05); the T allele was associated with lower BMI in the overall cohort (β = -0.10 kg/m², SE = 0.05; P = 0.03) and with smoking quantity in those in whom this was measured (n = 5,304) (β = 0.08, SE = 0.01; P < 0.0001). Neither smoking status (Pinteraction = 0.29) nor snus use (Pinteraction = 0.89) modified the association between the rs1051730 variant and BMI.

Abstract
BACKGROUND Although carbohydrate reduction of varying degrees is a popular and controversial dietary trend, potential long-term effects for health, and cancer in specific, are largely unknown. METHODS We studied a previously established low-carbohydrate, high-protein (LCHP) score in relation to the incidence of cancer and specific cancer types in a population-based cohort in northern Sweden. Participants were 62,582 men and women with up to 17.8 years of follow-up (median 9.7), including 3,059 prospective cancer cases. Cox regression analyses were performed for a LCHP score based on the sum of energy-adjusted deciles of carbohydrate (descending) and protein (ascending) intake labeled 1 to 10, with higher scores representing a diet lower in carbohydrates and higher in protein. Important potential confounders were accounted for, and the role of metabolic risk profile, macronutrient quality including saturated fat intake, and adequacy of energy intake reporting was explored. RESULTS For the lowest to highest LCHP scores, 2 to 20, carbohydrate intakes ranged from median 60.9 to 38.9% of total energy intake. Both protein (primarily animal sources) and particularly fat (both saturated and unsaturated) intakes increased with increasing LCHP scores. LCHP score was not related to cancer risk, except for a non-dose-dependent, positive association for respiratory tract cancer that was statistically significant in men. The multivariate hazard ratio for medium (9-13) versus low (2-8) LCHP scores was 1.84 (95% confidence interval: 1.05-3.23; p-trend = 0.38). Other analyses were largely consistent with the main results, although LCHP score was associated with colorectal cancer risk inversely in women with high saturated fat intakes, and positively in men with higher LCHP scores based on vegetable protein. CONCLUSION These largely null results provide important information concerning the long-term safety of moderate carbohydrate reduction and consequent increases in protein and, in this cohort, especially fat intakes. In order to determine the effects of stricter carbohydrate restriction, further studies encompassing a wider range of macronutrient intakes are warranted.

Abstract
BACKGROUND General health checks are common elements of health care in some countries. These aim to detect disease and risk factors for disease with the purpose of reducing morbidity and mortality. Most of the commonly used screening tests offered in general health checks have been incompletely studied. Also, screening leads to increased use of diagnostic and therapeutic interventions, which can be harmful as well as beneficial. It is, therefore, important to assess whether general health checks do more good than harm. OBJECTIVES We aimed to quantify the benefits and harms of general health checks with an emphasis on patient-relevant outcomes such as morbidity and mortality rather than on surrogate outcomes such as blood pressure and serum cholesterol levels. SEARCH METHODS We searched The Cochrane Library, the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Effective Practice and Organisation of Care (EPOC) Trials Register, MEDLINE, EMBASE, Healthstar, CINAHL, ClinicalTrials.gov and WHO International Clinical Trials Registry Platform (ICTRP) to July 2012. Two authors screened titles and abstracts, assessed papers for eligibility and read reference lists. One author used citation tracking (Web of Knowledge) and asked trialists about additional studies. SELECTION CRITERIA We included randomised trials comparing health checks with no health checks in adults unselected for disease or risk factors. We did not include geriatric trials. We defined health checks as screening general populations for more than one disease or risk factor in more than one organ system. DATA COLLECTION AND ANALYSIS Two authors independently extracted data and assessed the risk of bias in the trials. We contacted authors for additional outcomes or trial details when necessary. For mortality outcomes we analysed the results with random-effects model meta-analysis, and for other outcomes we did a qualitative synthesis as meta-analysis was not feasible. MAIN RESULTS We included 16 trials, 14 of which had available outcome data (182,880 participants). Nine trials provided data on total mortality (155,899 participants, 11,940 deaths), median follow-up time nine years, giving a risk ratio of 0.99 (95% confidence interval (CI) 0.95 to 1.03). Eight trials provided data on cardiovascular mortality (152,435 participants, 4567 deaths), risk ratio 1.03 (95% CI 0.91 to 1.17) and eight trials on cancer mortality (139,290 participants, 3663 deaths), risk ratio 1.01 (95% CI 0.92 to 1.12). Subgroup and sensitivity analyses did not alter these findings.We did not find an effect on clinical events or other measures of morbidity but one trial found an increased occurrence of hypertension and hypercholesterolaemia with screening and one trial found an increased occurence of self-reported chronic disease. One trial found a 20% increase in the total number of new diagnoses per participant over six years compared to the control group. No trials compared the total number of prescriptions, but two out of four trials found an increased number of people using antihypertensive drugs. Two out of four trials found small beneficial effects on self-reported health, but this could be due to reporting bias as the trials were not blinded. We did not find an effect on admission to hospital, disability, worry, additional visits to the physician, or absence from work, but most of these outcomes were poorly studied. We did not find useful results on the number of referrals to specialists, the number of follow-up tests after positive screening results, or the amount of surgery. AUTHORS' CONCLUSIONS General health checks did not reduce morbidity or mortality, neither overall nor for cardiovascular or cancer causes, although the number of new diagnoses was increased. Important harmful outcomes, such as the number of follow-up diagnostic procedures or short term psychological effects, were often not studied or reported and many trials had methodological problems. With the large number of participants and deaths included, the long follow-up periods used, and considering that cardiovascular and cancer mortality were not reduced, general health checks are unlikely to be beneficial.

Abstract
Aim The Västerbotten Intervention Programme (VIP) addresses cardiovascular disease and diabetes in the middle-aged population of Västerbotten County, Sweden. Self-reported health (SRH) is one of the risk factors for both conditions. The aim of this study was to analyse the development patterns of SRH among the VIP participants. Methods Cross-sectional data from 1990 to 2007 were used to analyse the prevalence of poor SRH among 101,396 VIP participants aged 40–60 years. Panel data were used to study the change in SRH among 25,695 persons aged 30–60 years, who participated in the VIP twice within a 10-year interval. Results Prevalence of poor SRH fluctuated between 1990 and 2007 in Västerbotten County. There was a temporary decline around 2000, with SRH continuously improving thereafter. The majority of panel participants remained in good SRH; over half of those with poor or fair SRH at baseline reported better SRH at follow-up. SRH declined in 19% of the panel participants, mostly among those who had good SRH at the baseline. The decline was common among both women and men, in all educational, age and marital status groups. Conclusions The SRH improvement among those with poor and fair SRH at baseline suggests that VIP has been successful in addressing its target population. However, the deterioration of SRH among 21% of the individuals with good SRH at baseline is of concern. From a public health perspective, it is important for health interventions to address not only the risk group but also those with a healthy profile to prevent the negative development among the seemingly healthy participants.

Abstract
In this systematic review, the authors aimed to assess the effectiveness of community programs for prevention of cardiovascular disease (CVD). They searched numerous electronic databases (CDSR, DARE, HTA, EED, and CENTRAL via the Cochrane Library, MEDLINE, MEDLINE In Process, EMBASE, CINAHL, PsycINFO, HMIC, and ASSIA) and relevant Web sites from January 1970 to mid-July 2008. Controlled studies of community programs for the primary prevention of CVD were included. Net changes in CVD risk factors were used to generate an overall index for net change in 10-year CVD risk. The authors identified 36 relevant community programs that took place between 1970 and 2008. These programs were multifaceted interventions employing combinations of media, screening, and counseling activities and environmental changes and were primarily evaluated using controlled before-after studies. In 7 studies, investigators reported changes in CVD/total mortality rates, and in 5 they reported net changes. In all cases, these net changes were positive but were largely nonsignificant. In 22 studies, investigators reported changes in physiologic CVD risk factors, and there was a positive trend in the calculated CVD risk score. The average net reduction in 10-year CVD risk was 0.65%. Community programs for CVD prevention appear to have generally achieved favorable changes in overall CVD risk and, with adaptation to current circumstances, deserve continued consideration as possible approaches to preventing CVD.

Abstract
Northern Sweden is a sparsely populated area with six hospitals and about 50 healthcare centers. The elderly population is a large proportion of the total of population, and the incidence of cardiovascular disease is high. The objective of this research was to analyze the costs and benefits of cardiac consultation in healthcare centers involving long-distance, remote-controlled, real-time echocardiography. The distance diagnostics were developed and tested in two healthcare centers. Experiences of the feasibility of this approach were used as a basis for an economic analysis with regard to heart failure. The societal costs for two different systems were calculated, namely, traditional hospital diagnosis versus distance diagnosis using the new system. The potential prime gainers were the patients. Their traveling time, and thereby their time costs, were significantly reduced. The quality of care may also have been improved. From the health authorities' perspective, the costs of the two systems were approximately equal. Since county council costs are not greatly affected, the large reduction in patient travel time and the improved quality of care ought to be a sufficient incentive for large-scale tests.

Abstract
AIMS To compare data on cardiovascular risk factor changes in lipids, insulin, proinsulin, fibrinolysis, leptin and C-reactive protein, and on diabetes incidence, in relation to changes in lifestyle. METHODS The study was a randomized lifestyle intervention trial conducted in northern Sweden between 1995 and 2000, in 168 individuals with impaired glucose tolerance (IGT) and body mass index above 27 at start. The intensive intervention group (n = 83) was subjected to a 1-month residential lifestyle programme. The usual care group (n = 85) participated in a health examination ending with a single counselling session. Follow-up was conducted at 1, 3 and 5 years. RESULTS At 1-year follow-up, an extensive cardio-metabolic risk factor reduction was demonstrated in the intensive intervention group, along with a 70% decrease of progress to type 2 diabetes. At 5-year follow-up, most of these beneficial effects had disappeared. Reported physical activity and fibre intake as well as high-density lipoprotein cholesterol were still increased, and fasting insulin and proinsulin were lower. CONCLUSIONS The intervention affected several important cardio-metabolic risk variables beneficially, and reduced the risk for type 2 diabetes, but the effects persisted only as long as the new lifestyle was maintained. Increased physical activity seemed to be the behaviour that was most easy to preserve.

Abstract
CONTEXT Geoffrey Rose's two principal approaches to public health intervention are (1) targeted strategies focusing on individuals at a personal increased risk of disease and (2) population-wide approaches focusing on the whole population. Beyond his discussion of the strengths and weaknesses of these approaches, there is no empiric work examining the conditions under which one of these approaches may be better than the other. METHODS This article uses mathematical simulations to model the benefits and costs of the two approaches, varying the cut points for treatment, effect magnitudes, and costs of the interventions. These techniques then were applied to the specific example of an intervention on blood pressure to reduce cardiovascular disease. FINDINGS In the general simulation (using an inverse logit risk curve), lower costs of intervention, treating people with risk factor values at or above where the slope on the risk curve is at its steepest (for targeted interventions), and interventions with larger effects on reducing the risk factor (for population-wide interventions) provided benefit/cost advantages. In the specific blood pressure intervention example, lower-cost population-wide interventions had better benefit/cost ratios, but some targeted treatments with lower cutoffs prevented more absolute cases of disease. CONCLUSIONS These simulations empirically evaluate some of Rose's original arguments. They can be replicated for particular interventions being considered and may be useful in helping public health decision makers assess potential intervention strategies.

Abstract
BACKGROUND The quality and outcomes framework is a financial incentive scheme that remunerates general practices in the UK for their performance against a set of quality indicators. Incentive schemes can increase inequalities in the delivery of care if practices in affluent areas are more able to respond to the incentives than are those in deprived areas. We examined the relation between socioeconomic inequalities and delivered quality of clinical care in the first 3 years of this scheme. METHODS We analysed data extracted automatically from clinical computing systems for 7637 general practices in England, data from the UK census, and data for characteristics of practices and patients from the 2006 general medical statistics database. Practices were grouped into equal-sized quintiles on the basis of area deprivation in their locality. We calculated overall levels of achievement, defined as the proportion of patients who were deemed eligible by the practices for whom the targets were achieved, for 48 clinical activity indicators during the first 3 years of the incentive scheme (from 2004-05 to 2006-07). FINDINGS Median overall reported achievement was 85.1% (IQR 79.0-89.1) in year 1, 89.3% (86.0-91.5) in year 2, and 90.8% (88.5-92.6) in year 3. In year 1, area deprivation was associated with lower levels of achievement, with median achievement ranging from 86.8% (82.2-89.6) for quintile 1 (least deprived) to 82.8% (75.2-87.8) for quintile 5 (most deprived). Between years 1 and 3, median achievement increased by 4.4% for quintile 1 and by 7.6% for quintile 5, and the gap in median achievement narrowed from 4.0% to 0.8% during this period. Increase in achievement during this time was inversely associated with practice performance in previous years (p<0.0001), but was not associated with area deprivation (p=0.062). INTERPRETATION Our results suggest that financial incentive schemes have the potential to make a substantial contribution to the reduction of inequalities in the delivery of clinical care related to area deprivation.

Abstract
AIMS It is well established that the main cause of the development of cardiovascular disease can be found in unhealthy lifestyle habits. In our study, we wanted to explore the long-term predictors of self-reported lifestyle changes in a middle-aged population after screening for cardiovascular risk factors 10 years earlier. METHODS We conducted a 10-year follow-up telephone interview on self-reported lifestyle changes in a rural population in south-eastern Sweden, after a cardiovascular screening programme. The population comprised 90% of all inhabitants (n=705) aged 40-59 years at baseline, and 90% of these (n=629) were reached for the telephone interview. RESULTS When multivariate logistic regression was used, a higher success rate for lifestyle changes was independently associated with female gender (odds ratio (OR)=1.56, 95% confidence interval (CI) 1.11-2.18). When stratified for gender, significant predictors for success in men were prevalent cardiovascular risk conditions (OR=4.77, 95% CI 2.18-10.5; p<0.001) and previous myocardial infarction (OR=22.8, 95% CI 4.73-110; p<0.001) at baseline. For women, elevated blood pressure (> or = 160 and/or > or = 90 mmHg) measured at baseline (OR=1.84, 95% CI 1.12-3.02; p=0.016) was significantly associated with successful lifestyle changes. Smoking at baseline was also associated with significant success: OR=3.36 (95% CI:2.05-5.51; p<0.001) and OR=1.81 (95% CI 1.11-2.95; p=0.017) for men and women, respectively. CONCLUSIONS Female gender was associated with significant improvements in self-reported lifestyle changes. Furthermore, smoking, a medical history of diabetes, hypertension, angina pectoris or myocardial infarction at baseline predicted success in lifestyle change in this 10-year follow-up study.

Abstract
Health is a universal human aspiration and a basic human need. The development of society, rich or poor, can be judged by the quality of its population's health, how fairly health is distributed across the social spectrum, and the degree of protection provided from disadvantage due to ill-health. Health equity is central to this premise and to the work of the Commission on Social Determinants of Health. Strengthening health equity--globally and within countries--means going beyond contemporary concentration on the immediate causes of disease. More than any other global health endeavour, the Commission focuses on the "causes of the causes"--the fundamental structures of social hierarchy and the socially determined conditions these create in which people grow, live, work, and age. The time for action is now, not just because better health makes economic sense, but because it is right and just. The outcry against inequity has been intensifying for many years from country to country around the world. These cries are forming a global movement. The Commission on Social Determinants of Health places action to ensure fair health at the head and the heart of that movement.

Abstract
Background Public health interventions are directed towards social systems and it is difficult to foresee all consequences. While targeted outcomes may be positively influenced, interventions may at worst be counterproductive. To include self-reported health in an evaluation is one way of addressing possible side-effects. This study is based on a 10 year follow-up of a cardiovascular community intervention programme in northern Sweden. Methods Both quantitative and qualitative approaches were used to address the interaction between changes in self-rated health and risk factor load. Qualitative interviews contributed to an analysis of how the outcome was influenced by health related norms and attitudes. Results Most people maintained a low risk factor load and a positive perception of health. However, more people improved than deteriorated their situation regarding both perceived health and risk factor load. "Ideal types" of attitude sets towards the programme, generated from the interviews, helped to interpret an observed polarisation for men and the lower educated. Conclusion Our observation of a socially and gender differentiated intervention effect suggests a need to test new intervention strategies. Future community interventions may benefit from targeting more directly those who in combination with high risk factor load perceive their health as bad and to make all participants feel seen, confirmed and involved.

Abstract
Review of the community-based CVD intervention programs suggests that a number of components have been successful using varying methods and materials for CVD risk reduction. It should be noted, however, that in multi-intervention programs it is often difficult to determine which components of the intervention were responsible for the overall success of the study. The community-based approach to CVD prevention is generalizable, cost-effective (because of the use of mass communication methods), and has the potential for modifying the environment and influencing health policies. Based on the experiences and successes of a number of community projects, recommendations have been proposed for developing future programs. Although they are not totally comprehensive, it has been suggested that a community-based intervention program should consider the following recommendations: 1) An understanding of the community: the needs and priorities of the community should be assessed, and close collaboration with individuals from the community, including community leaders, opinion leaders, community health care providers, and community organizations from various sectors of the community, should be consulted. Efforts should be focused on underserved and vulnerable populations. 2) Inclusion of community activities: these activities should be integrated within the context of the community environment, including primary health care services, voluntary organizations, grocery stores, restaurants, work sites, schools, and local media. 3) Inclusion mass media messages: the mass media can provide information and reinforcement of the behavior change. 4) Develop cost-effective interventions to assure that the community is exposed to an effective dose of the intervention. 5) Work with community organizations to help change social and physical environments to make them more conducive to health and healthy life-styles changes. 6) Develop a reliable monitoring and evaluation system: monitor the change process and conduct summary evaluations. 7) Disseminate the results to ensure that the benefits from the community program reach all communities. 8) For national implementation, the intervention program should work closely with national policy makers throughout the project.

Abstract
OBJECTIVE To study possible social predictors for reduction of hyperlipidaemia in subjects offered lifestyle intervention in primary health care after an opportunistic screening. SETTING Primary health care in Sollentuna, Sweden. DESIGN Follow-up study of changes in high lipid levels in men and women aged 20-60 years participating in a voluntary screening and cardiovascular prevention programme. SUBJECTS AND MAIN OUTCOME MEASURES A total of 1904 individuals had a follow-up visit registered after a mean of 466 days. Men and women with raised lipid levels (serum cholesterol = 6.5 mmol/l, and/or triglycerides = 2.3 mmol/l) at baseline were compared with normolipidaemic participants. Data on social characteristics such as education, occupation, marital status, and income were collected from national censuses. Associations between socioeconomic factors and changes in lipid levels were studied. RESULTS Men and women with hyperlipidaemia were generally (p < 0.001) older (men 6-8 years, women 8-10 years) and less educated than normolipidaemic subjects. Significant predictors for reducing hypercholesterolaemia were younger age, OR 0.97 (0.95-1.00) for increasing age, and longer education, OR 0.47 (0.24-0.91) for low education (<9 years). Foreign-born subjects were more likely to achieve a high success rate in reducing hypercholesterolaemia, OR 3.43 (1.00-11.8), than the Swedish-born. No significant predictors were detected for reduction of high triglyceride levels. CONCLUSION A successful reduction of high cholesterol levels was associated with younger age and longer education in a primary health care-based programme for cardiovascular prevention.

Abstract
OBJECTIVES To estimate risk factors for stroke, to examine how different categories of patients with increased blood pressure are associated with risk for first-ever stroke event, and to estimate the proportions of these categories in a geographically defined population in northern Sweden. SETTING The study was nested within the Västerbotten Intervention Program and the Northern Sweden MONICA cohorts. DESIGN AND PARTICIPANTS A population-based cross-sectional study and an incident case-control study were carried out. The incident case-control study comprised 129 cases of first-ever stroke diagnosed during 1985-96, with two randomly selected controls per case, chosen from the same geographically defined population. The cross-sectional study was based on 59,735 participants. Blood pressure status was categorized as: normotensive [systolic blood pressure (SBP) <140 mmHg and diastolic blood pressure (DBP) <90 mmHg]; treated and adequately controlled hypertension (SBP <140 mmHg and DBP <90 mmHg); treated but poorly controlled hypertension (SBP > or = 140 mmHg or DBP > or = 90 mmHg, or both); untreated hypertension (SBP > or = 140 mmHg or DBP > or = 90 mmHg, or both); newly detected increased blood pressure (SBP > or = 140 mmHg or DBP > or = 90 mmHg, or both). MAIN OUTCOME MEASURE Risk for first-ever stroke. RESULTS In the cross-sectional study, 68% of individuals were normotensive, 3% had treated and adequately controlled hypertension, 6% had treated but poorly controlled hypertension, 7% had untreated hypertension, and 16% had newly detected increased blood pressure. In univariate analysis of the case-control study, history of diabetes, daily smoking, obesity, increased blood pressure and the hypertension categories 'treated but poorly controlled' and 'untreated' were associated with an increased stroke risk. In multivariate logistic regression analysis, only diabetes and the hypertension categories treated but poorly controlled and untreated remained significant, with odds ratios 6.1 (95% confidence interval 2.4 to 15.3) and 4.3 (95% confidence interval 1.7 to 10.5), respectively. Only one of the 129 individuals who suffered stroke had treated and adequately controlled hypertension. CONCLUSIONS The study illustrates the importance of adequate blood pressure control and, at the same time, that the vast majority in the population with increased blood pressure did not receive optimal care. Thus the 'rule of halves' still exists, and the high remaining risk in poorly treated hypertensive individuals in Sweden is remarkable and requires attention from the medical profession.

Abstract
BACKGROUND Short body height is associated with increased risk for coronary heart disease; however, mechanisms are not fully explained. In this study, associations between body height and serum cholesterol, non-high-density lipoprotein (non-HDL cholesterol) and high-density lipoprotein (HDL cholesterol) were investigated. METHODS Prospective cohort study of middle-aged men from Helsingborg, Sweden starting 1990. Two birth-year cohorts were invited at 37, 40 and 43 years of age; participation at baseline was 991 (68%). Serum and HDL cholesterol, systolic and diastolic blood pressure, weight, height, waist and hip circumferences were measured. Non-HDL cholesterol, body mass index (BMI) and waist/ hip ratio (WHR) were calculated. The participants completed a questionnaire covering lifestyle variables. RESULTS There were statistically significant inverse correlations between body height and serum cholesterol (-0.11) and non-HDL cholesterol (-0.12). One standard deviation, 6.7 cm, taller body height was associated with a lower serum cholesterol (-0.12 mmol/l) and a lower non-HDL cholesterol (-0.13 m mol/l; p < 0.001). These associations remained when adjusted for BMI and WHR. Men with serum cholesterol equal to or above 6.5 mmol/l were significantly shorter (mean 178.71 cm) than men with serum cholesterol below 6.5 mmol/l (mean 179.71 cm). In addition, BMI and WHR were positively associated with serum and non-HDL cholesterol and inversely associated with HDL cholesterol. The change in cholesterol levels over the six-year follow-up was significantly associated to the change in BMI and WHR. CONCLUSIONS Body height had an independent and inverse relation to serum cholesterol and non-HDL cholesterol in middle-aged men, and the lipid pattern suggests that the underlying mechanism might be different from the traditional association between lipids and the metabolic syndrome. Although the direct clinical implication is limited, our results may help to explain the association between short height and risk of myocardial infarction.

Abstract
BACKGROUND Since smoking behaviour is determined by social context, the best way to reduce the prevalence of smoking may be to use community-wide programmes which use multiple channels to provide reinforcement, support and norms for not smoking. OBJECTIVES To assess the effectiveness of community interventions for reducing the prevalence of smoking. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group specialised register, MEDLINE (1966-August 2001) and EMBASE (1980-August 2001) and reference lists of articles. SELECTION CRITERIA Controlled trials of community interventions for reducing smoking prevalence in adult smokers. The primary outcome was smoking behaviour. DATA COLLECTION AND ANALYSIS Data were extracted by one person and checked by a second. MAIN RESULTS Thirty two studies were included, of which seventeen included only one intervention and one comparison community. Only four studies used random assignment of communities to either the intervention or comparison group. The population size of the communities ranged from a few thousand to over 100,000 people. Change in smoking prevalence was measured using cross-sectional follow-up data in 27 studies. The estimated net decline ranged from -1.0% to 3.0% for men and women combined (10 studies). For women, the decline ranged from -0.2% to + 3.5% per year (n=11), and for men the decline ranged from -0.4% to +1.6% per year (n=12). Cigarette consumption and quit rates were only reported in a small number of studies. The two most rigorous studies showed limited evidence of an effect on prevalence. In the US COMMIT study there was no differential decline in prevalence between intervention and control communities, and there was no significant difference in the quit rates of heavier smokers who were the target intervention group. In the Australian CART study there was a significantly greater quit rate for men but not women. REVIEWER'S CONCLUSIONS The failure of the largest and best conducted studies to detect an effect on prevalence of smoking is disappointing. A community approach will remain an important part of health promotion activities, but designers of future programmes will need to take account of this limited effect in determining the scale of projects and the resources devoted to them.

Abstract
OBJECTIVE The aims of the present study were (1) to evaluate the degree to which underreporting of energy intake by repeated 24-hour recalls was related to gender, age, weight status, day of interview, educational level, smoking habits and area of living, and (2) to compare the dietary characteristics of underreporters with those of others. DESIGN Cross-sectional study. Ten 24-hour recalls were performed during a one-year period. SETTING The Västerbotten intervention programme of cardiovascular disease and diabetes in Northern Sweden. SUBJECTS Ninety-four men and 99 women in four age groups: 30, 40, 50 and 60 years. RESULTS The prevalence of men and women with a food intake level (FIL; reported energy intake divided by estimated basal metabolic rate) below 1.2 was 44% and 47%, respectively. The youngest age group had higher FIL values than the oldest age group for both men (1.5 versus 1.1) and women (1.4 versus 1.1). The prevalence and magnitude of underreporting were directly related to body mass index (BMI; correlation coefficient: -0.47 (men) and -0.55 (women)). Smokers had a lower FIL value (1.1) than non-smokers (1.3). The nutrient density was lower for the group with high FIL values for protein and calcium and higher for fat and sucrose. The upper FIL group often had higher intake frequencies and larger portion sizes than the lower FIL group. CONCLUSIONS Underreporting of energy intake is prevalent when 24-hour recalls are used, but the prevalence differs between sub-groups in the population. BMI was the main predictor of underreporting but also old age and smoking seem to contribute in this aspect. Socially desirable food items were not underreported to the same extent as socially undesirable food items. The intake frequencies and portion sizes partly explained the differences in FIL.

Abstract
OBJECTIVES To examine to what extent traditional biomedical risk factors and social factors can predict, separately or jointly, first-ever stroke event, and to explore to what extent other risk factors might add to hypertension/elevated blood pressure as a stroke risk factor. DESIGN An incident case-referent study. SETTING The study was nested within the Västerbotten Intervention Program (VIP) and the Northern Sweden MONICA cohorts. SUBJECTS The study involves 129 stroke cases with two randomly selected referents per case from the same study cohorts. RESULTS History of diabetes, daily smoking, obesity (body mass index greater than or = 30 kg m(-2)), hypertension and living as an unmarried person were associated with an increased risk in univariate analysis. However, in the multivariate logistic regression analysis, only hypertension, diabetes and single marital status remained significant. There was a statistically significant interaction between hypertension and smoking and stroke. Interaction of possible clinical relevance was also observed between hypertension, history of diabetes and stroke. CONCLUSIONS The study both emphasizes the multifactorial nature of stroke and illustrates that knowledge of interactions offers different strategic approaches when preventing stroke in clinical work. It is important, but not enough, to focus on blood pressure control. Diabetes prevention as well as prevention of smoking must also be considered as factors of major importance.

Abstract
BACKGROUND AND PURPOSE Diabetic subjects have a 3- to 6-fold increased risk for stroke compared with nondiabetic subjects, and hyperinsulinemia shows strong and consistent associations with a cluster of cardiovascular risk factors. Methods separating proinsulin from (true) insulin have demonstrated proinsulin to be more strongly associated with cardiovascular disease than insulin. The present study evaluates the associations between first-ever stroke, proinsulin, and insulin. METHODS In this incident case-referent study of a nondiabetic population, 94 cases of first-ever stroke (59 men and 35 women) were individually age- and sex-matched to 178 referents. Blood sampling was collected before the stroke event. Proinsulin and insulin were measured with highly sensitive 2-site sandwich enzyme-linked immunosorbent assays. RESULTS In the study population, high proinsulin concentration more than tripled the risk for first-ever stroke after adjustments for total cholesterol, systolic blood pressure, smoking, body mass index, and insulin, with an odds ratio of 3.4 (95% CI, 1.4 to 8.4). In women the risk was even more pronounced, with an odds ratio of 13.7 (95% CI, 1.3 to 146). Synergy was found between proinsulin and systolic blood pressure. In women, synergy was also found between proinsulin and diastolic blood pressure as well as between insulin and both blood pressures. CONCLUSIONS High levels of proinsulin may predict later occurrence of first-ever stroke in a nondiabetic population.

Abstract
OBJECTIVES To identify different types of dilution bias in population-based interventions and to suggest measures for handling these methodological problems. DESIGN Literature review plus analysis of data from a population-based intervention against cardiovascular disease in a Swedish municipality. MAIN RESULTS The effects of an intervention on mortality and morbidity were much more diluted by non-intervening factors, dissemination to areas outside the intervention area, social diffusion, population mobility and time than by using intermediate outcome measures. CONCLUSIONS Theoretically, changes in scientifically well documented risk factors, for example, intermediate outcome measures, should be preferred to using morbidity or mortality as outcome measures.
