- BACKGROUND: There is a lack of research about the experiences of participating in weight-reducing interventions. The aim of this study was to explore barriers and facilitators to weight-loss experienced by participants in a diet intervention for middle-aged to older women in the general population in Northern Sweden.METHOD: In the intervention the women were randomised to eat either a Palaeolithic-type diet or a diet according to Nordic Nutrition recommendations for 24 months. A strategic selection was made of women from the two intervention groups as well as from the drop-outs in relation to social class, civil status and age. Thematic structured interviews were performed with twelve women and analysed with qualitative content analyses.RESULTS: The results showed that the women in the dietary intervention experienced two main barriers - struggling with self (related to difficulties in changing food habits, health problems, lack of self-control and insecurity) and struggling with implementing the diet (related to social relations and project-related difficulties) - and two main facilitators- striving for self-determination (related to having clear goals) and receiving support (from family/friends as well as from the project) - for weight-loss. There was a greater emphasis on barriers than on facilitators.CONCLUSION: It is important to also include drop-outs from diet interventions in order to fully understand barriers to weight-loss. A gender-relational approach can bring new insights into understanding experiences of barriers to weight-loss.

- Background: Diabetic patients experience stimulated coagulation and dysfibrinolysis, which is associated with an increased risk of cardiovascular events. This imbalance may precede the manifest diagnosis. We investigated whether elevated antigen levels of tissue plasminogen activator (tPA), plasminogen activator inhibitor-1 (PAI-1), the tPA/PAI-1 complex, or von Willebrand Factor (VWF) precede type 2 diabetes mellitus (T2DM) diagnosis, and whether this elevation occurs before increased fasting plasma glucose (FPG) or 2-hour plasma glucose (2hPG) in individuals who later develop T2DM.Methods: We conducted a prospective incident case-referent study within the Vasterbotten Intervention Programme. Cardiovascular risk factor data as well as FPG and 2hPG and blood samples for future research were collected at a baseline health examination between 1989 and 2000, (n= 28 736). During follow-up in January 2001, 157 cases had developed T2DM. Referents without T2DM were matched for sex, age, and year of participation (n=277). Subgroup analysis was performed for cases with normal baseline glucose levels (FPG <6.1 mmol/L and 2hPG < 8.9 mmol/L) and cases with elevated levels (FPG 6.1-6.9 mmol/L and/or 2hPG 8.9-12.1 mmol/L).Results: After adjusting for BMI, family history of diabetes, physical activity, smoking, systolic blood pressure and levels of C-reactive protein and triglycerides, independent associations were found between incident T2DM and elevated levels of tPA (OR=1.54, 95% CI 1.06-2.23), PAI-1 (OR=1.61, 95% CI 1.14-2.28), and tPA/PAI-1 complex (OR=2.45, 95% CI 1.56-3.84). In participants with normal glucose levels, PAI-1 (OR=2.06, 95% CI 1.10 - 3.86) exhibited an independent relationship with incident T2DM after the adjustments.Conclusions: Elevated levels of fibrinolytic variables precede the manifestation of T2DM after adjusting for metabolic and cardiovascular risk factors and can be detected several years before changes in glucose tolerance.

- Background: The prevalence of diabetes in the world is projected to rise from 2.8% in the year 2000 to 4.4% in 2030, an increase suggesting an ongoing global epidemic of diabetes.Objective: To examine time trends in fasting and 2-h glucose concentrations, prevalence and 10-year cumulative incidence of diabetes, and the role of education in these trends. Design: Each year the Vasterbotten Intervention Programme invites all 40, 50, and 60-year-old individuals to a health survey, which includes a cardiovascular risk factor screening and oral glucose tolerance test. The cross-sectional part of the study is based on health examinations conducted between 1990 and 2007 (n = 102,822). The prospective subset (panel dataset) of the study is based on individuals who have had two health examinations 10 years apart and were not defined as having diabetes at their first health examination (n = 23,546).Results: Between 1990 and 2007, the mean population fasting glucose concentration increased 0.5 mmol/L. Comparing the prevalence in 1990-1995 with 2002-2007 demonstrated a significant 44% increase in men (p < 0.001) and a significant 17% increase in women (p < 0.001). Socioeconomic status, here represented by education, clearly influenced both prevalence and incidence of diabetes and glucose concentration. In all time periods and in all age groups, individuals with low education were more likely to have or get diabetes. The 10-year risk of developing diabetes was four to five times higher in the oldest age group (50-60 years) compared with the youngest (30-40 years). A 30% reduction in the 10-year risk of developing diabetes was found in women (p < 0.001) between 2000-2003 and 2004-2007.Conclusions: Despite a clear increase in glucose concentrations and diabetes prevalence between 1990 and 2007, especially in men, there was a decline in the 10-year risk of developing diabetes in women between 2000-2003 and 2004-2007.

- BACKGROUND: Cardiovascular disease and type 2 diabetes are two of the most common public health diseases, and up to 80 % of the cases may be prevented by lifestyle modification. The physiological effects of lifestyle-focused treatment are relatively well studied, but how patients actually experience such treatments is still rather unclear.PURPOSE: The aim of this study was to explore how patients experience lifestyle-focused group treatment in primary and secondary prevention of cardiovascular disease and type 2 diabetes.METHOD: Qualitative interviews were conducted with 19 patients attending lifestyle-focused group treatment based on social cognitive theory at a behavioral medicine clinic in northern Sweden. The interviews were transcribed verbatim and analyzed according to Malterud's systematic text condensation.RESULTS: The study shows that patients participating in this kind of group-based lifestyle treatment went through a process of self-development which deepened their understanding of own responsibility for health and improved their skills in finding support in others. The process could be tracked through three different themes (the holistic view, personal responsibility, and group treatment) which together reflected the most essential parts of the informants' experience and showed the patient as an active decision maker struggling to adopt the principles of behavioral change.CONCLUSION: Lifestyle-focused group treatment, based on social cognitive theory, was shown to stimulate different components that strengthen patients' self-efficacy for long-term behavioral change.

- BACKGROUND: Complementary strategies to shift risk factor population distributions and target high-risk individuals are required to reduce the burden of type 2 diabetes and cardiovascular disease (CVD).PURPOSE: To examine secular changes in glucose and CVD risk factors over 20 years during an individual and population-based CVD prevention program in Västerbotten County, Sweden.METHODS: Population-based health promotion intervention was conducted and annual invitation for individuals turning 40, 50, and 60 years to attend a health assessment, including an oral glucose tolerance test, biochemical measures, and a questionnaire. Data were collected between 1991 and 2010, analyzed in 2012 and available for 120,929 individuals. Linear regression modeling examined age-adjusted differences in CVD risk factor means over time. Data were direct-age-standardized to compare disease prevalence.RESULTS: Between 1991-1995 and 2006-2010, mean age-adjusted cholesterol (men=-0.53, 95% CI=-0.55, -0.50 mmol/L; women=-0.48, 95% CI=-0.50, -0.45 mmol/L) and systolic blood pressure declined (men=-3.06, 95% CI=-3.43, -2.70 mm Hg; women=-5.27, 95% CI=-5.64, -4.90 mm Hg), with corresponding decreases in the age-standardized prevalence of hypertension and hyperlipidemia. Mean age-adjusted 2-hour plasma glucose (men=0.19, 95% CI=0.15, 0.23 mmol/L; women=0.08, 95% CI=0.04, 0.11 mmol/L) and BMI increased (men=1.12, 95% CI=1.04, 1.21; women=0.65, 95% CI=0.55, 0.75), with increases in the age-standardized prevalence of diabetes and obesity.CONCLUSIONS: These data demonstrate the potential of combined individual- and population-based approaches to CVD risk factor control and highlight the need for additional strategies addressing hyperglycemia and obesity.

- Background/Objectives: Short-term studies have suggested beneficial effects of a Palaeolithic-type diet (PD) on body weight and metabolic balance. We now report the long-term effects of a PD on anthropometric measurements and metabolic balance in obese postmenopausal women, in comparison with a diet according to the Nordic Nutrition Recommendations (NNR).Subjects/Methods: Seventy obese postmenopausal women (mean age 60 years, body mass index 33 kg/m(2)) were assigned to an ad libitum PD or NNR diet in a 2-year randomized controlled trial. The primary outcome was change in fat mass as measured by dual-energy X-ray absorptiometry.Results: Both groups significantly decreased total fat mass at 6 months (-6.5 and-2.6 kg) and 24 months (-4.6 and-2.9 kg), with a more pronounced fat loss in the PD group at 6 months (P<0.001) but not at 24 months (P=0.095). Waist circumference and sagittal diameter also decreased in both the groups, with a more pronounced decrease in the PD group at 6 months (-11.1 vs-5.8 cm, P=0.001 and-3.7 vs-2.0 cm, P<0.001, respectively). Triglyceride levels decreased significantly more at 6 and 24 months in the PD group than in the NNR group (P<0.001 and P=0.004). Nitrogen excretion did not differ between the groups.Conclusions: A PD has greater beneficial effects vs an NNR diet regarding fat mass, abdominal obesity and triglyceride levels in obese postmenopausal women; effects not sustained for anthropometric measurements at 24 months. Adherence to protein intake was poor in the PD group. The long-term consequences of these changes remain to be studied.

- BACKGROUND: High cholesterol is identified as a major risk factor for chronic non-communicable diseases, especially cardiovascular and cerebrovascular diseases. Monitoring trends of cholesterol levels and comparing trends across population groups are important to assess population distribution and risks related to cholesterol change over time. Cholesterol surveillance data are lacking, even in high-income countries.OBJECTIVES: To describe the trends in cholesterol and triglyceride levels in different population groups and to estimate the risk of developing hypercholesterolemia and hypertriglyceridemia in Västerbotten County, Sweden during 1990-2010.DESIGNS AND METHODS: Since 1990, 133,082 individuals living in Västerbotten County, Northern Sweden, invited on their 30th, 40th, 50th and 60th birthdays, participated in the Västerbotten Intervention Program. Ten years after baseline data collection, 34,868 individuals were surveyed for a second time. In addition to a self-administered health questionnaire (that included information on socioeconomic status, demographics, self-reported health and lifestyle behaviours), blood cholesterol and triglyceride were examined.RESULTS: The level and prevalence of hypercholesterolemia decreased significantly from 1990 to 2007, but the trends began to increase during 2008-2010 in men, women, and in all educational groups. Men had significantly higher serum triglyceride levels than women and their cholesterol levels were similar to those of the women. This study shows that those with basic education and who live in rural inlands had consistently higher triglyceride level than those who live in the city and have higher educational attainments. People with basic education are also at higher risk of developing hypercholesterolemia and hypertriglyceridemia at 10-year follow-up; the risk is much higher among the older cohorts, particularly women. During 1990-2010, the proportion of participants who reported treatment with lipid-lowering agents increased from 1.1% to 9.6% among men and 0.5% to 5.3% among women. About 60% of those treated achieved treatment goals for cholesterol or triglycerides.CONCLUSIONS: The increasing trend in cholesterol level in the Västerbotten population during 2008-2010 needs to be closely monitored. Addressing the unequal distribution of cholesterol, as well as other risk factors such as obesity, physical inactivity, high blood glucose, among those with basic education, and particularly among populations in rural areas are important to prevent higher burdens of chronic non-communicable diseases in this population.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To examine the relationship between "traditional Sami" dietary pattern and mortality in a general northern Swedish population.STUDY DESIGN: Population-based cohort study.METHODS: We examined 77,319 subjects from the Västerbotten Intervention Program (VIP) cohort. A traditional Sami diet score was constructed by adding 1 point for intake above the median level of red meat, fatty fish, total fat, berries and boiled coffee, and 1 point for intake below the median of vegetables, bread and fibre. Hazard ratios (HR) for mortality were calculated by Cox regression.RESULTS: Increasing traditional Sami diet scores were associated with slightly elevated all-cause mortality in men [Multivariate HR per 1-point increase in score 1.04 (95% CI 1.01-1.07), p=0.018], but not for women [Multivariate HR 1.03 (95% CI 0.99-1.07), p=0.130]. This increased risk was approximately equally attributable to cardiovascular disease and cancer, though somewhat more apparent for cardiovascular disease mortality in men free from diabetes, hypertension and obesity at baseline [Multivariate HR 1.10 (95% CI 1.01-1.20), p=0.023].CONCLUSIONS: A weak increased all-cause mortality was observed in men with higher traditional Sami diet scores. However, due to the complexity in defining a "traditional Sami" diet, and the limitations of our questionnaire for this purpose, the study should be considered exploratory, a first attempt to relate a "traditional Sami" dietary pattern to health endpoints. Further investigation of cohorts with more detailed information on dietary and lifestyle items relevant for traditional Sami culture is warranted.
