Abstract
Starch in white wheat bread (WB) induces high postprandial glucose and insulin responses. For rye bread (RB), the glucose response is similar, whereas the insulin response is lower. In vitro studies suggest that polyphenol-rich berries may reduce digestion and absorption of starch and thereby suppress postprandial glycemia, but the evidence in humans is limited. We investigated the effects of berries consumed with WB or RB on postprandial glucose and insulin responses. Healthy females (n = 13-20) participated in 3 randomized, controlled, crossover, 2-h meal studies. They consumed WB or RB, both equal to 50 g available starch, with 150 g whole-berry purée or the same amount of bread without berries as reference. In study 1, WB was served with strawberries, bilberries, or lingonberries and in study 2 with raspberries, cloudberries, or chokeberries. In study 3, WB or RB was served with a mixture of berries consisting of equal amounts of strawberries, bilberries, cranberries, and blackcurrants. Strawberries, bilberries, lingonberries, and chokeberries consumed with WB and the berry mixture consumed with WB or RB significantly reduced the postprandial insulin response. Only strawberries (36%) and the berry mixture (with WB, 38%; with RB, 19%) significantly improved the glycemic profile of the breads. These results suggest than when WB is consumed with berries, less insulin is needed for maintenance of normal or slightly improved postprandial glucose metabolism. The lower insulin response to RB compared with WB can also be further reduced by berries.

Abstract
OBJECTIVE To assess the cost-effectiveness of insulin detemir compared with Neutral Protamine Hagedorn (NPH) insulin when initiating insulin treatment in people with type 2 diabetes mellitus (T2DM) in Denmark, Finland, Norway, and Sweden. METHODS Efficacy and safety data were derived from a 20-week multi-centre randomized controlled head-to-head clinical trial comparing insulin detemir and NPH insulin in insulin naïve people with T2DM, and short-term (1-year) cost effectiveness analyses were performed. As no significant differences in HbA1c were observed between the two treatment arms, the model was based on significant differences in favour of insulin detemir in frequency of hypoglycaemia (Rate-Ratio = 0.52; CI = 0.44-0.61) and weight gain (Δ = 0.9 kg). Model outcomes were measured in Quality Adjusted Life Years (QALYs) using published utility estimates. Acquisition costs for insulin and direct healthcare costs associated with non-severe hypoglycaemic events were obtained from National Health Service public sources. One-way and probabilistic sensitivity analyses were performed. RESULTS Based on lower incidence of non-severe hypoglycaemic events and less weight gain, the QALY gain from initiating treatment with insulin detemir compared with NPH insulin was 0.01 per patient per year. Incremental cost-effectiveness ratios for the individual countries were: Denmark, Danish Kroner 170,852 (€22,933); Finland, €28,349; Norway, Norwegian Kroner 169,789 (€21,768); and Sweden, Swedish Krona 226,622 (€25,097) per QALY gained. Possible limitations of the study are that data on hypoglycaemia and relative weight benefits from a clinical trial were combined with hypoglycaemia incidence data from observational studies. These populations may have slightly different patient characteristics. CONCLUSIONS The lower risk of non-severe hypoglycaemia and less weight gain associated with using insulin detemir compared with NPH insulin when initiating insulin treatment in insulin naïve patients with type 2 diabetes provide economic benefits in the short-term. Based on cost/QALY threshold values, this represents good value for money in the Nordic countries. Using a short-term modelling approach may be conservative, as reduced frequency of hypoglycaemia and less weight gain may also have positive long-term health-related implications.

Abstract
AIMS To describe socioeconomic characteristics of participants and their effect on uptake and completion of the implementation project (FIN-D2D) for the National Type 2 Diabetes Prevention Programme. Furthermore, to assess the effectiveness of individual vs. group intervention during one-year follow-up. METHODS At baseline, 2820 men and 5764 women aged <65 years participated in the non-randomized implementation project in primary health care setting; one-year follow-up was available for 1067 men and 2122 women. Socioeconomic status included education and occupation. Interventions were individual and/or group-based. The changes in cardiovascular risk factors and glucose tolerance were used as measures of the effectiveness of intervention. RESULTS 68.4% of the men and 69.8% of the women participated in some of the intervention modalities offered. Low education and not working were related to active participation in the intervention in men. 88.2% of men and 76.1% of women selected the individual instead of group intervention. The effectiveness of individual vs. group interventions did not differ, except for minor changes in systolic blood pressure in women and glucose tolerance in men. CONCLUSIONS Socioeconomic status modulated participation in interventions. Both types of intervention worked equally well, but participation in group intervention was low.

Abstract
OBJECTIVE The level of physical activity (PA) of pregnant women in Finland is unknown. Even more limited is our knowledge of PA of women at high risk for gestational diabetes mellitus (GDM). METHODS The women (n=54) were randomly assigned to a lifestyle intervention group (n=27) including exercise advice by a physiotherapist six times during pregnancy or to a control group (n=27) without additional exercise advice. Outcomes of the present study were required sample size, timing of counselling and change of PA. PA was retrospectively reported during 12 months before pregnancy and recorded one week monthly during pregnancy. RESULTS Individualized counselling by a physiotherapist resulted in small changes of recreational PA (2.7 MET hours/week, p=0.056) up to gestational week 25 compared with the similar decreasing tendency of PA in the control group. The women decreased recreational PA after week 30. Sample size of 550 women at high risk for GDM per group would be needed for a PA study. CONCLUSIONS The optimal time window for increasing PA must be earlier than in the last trimester of pregnancy. Sample size for a study to increase PA by 2.7 MET hours/week on pregnant women at high risk of GDM should be about 550 per group.

Abstract
AIM Abundant evidence suggests that depression is a risk factor for cardiovascular disease and metabolic syndrome. Systemic low-grade inflammation and evolving abdominal obesity are hypothesised to be underlying mechanisms explaining the relationship. To test this hypothesis we examined the association of depressive symptoms and inflammation in developing abdominal obesity. METHODS The subjects were 726 non-diabetic men, 42-60 of age at baseline, participating in the Kuopio Ischemic Heart Disease Risk Factor Study. The follow-up data was collected 11 years after the baseline. Low-grade inflammation was defined as serum C-reactive protein ≥2 mg/l and depressive symptoms were assessed by the Human Population Laboratory Depression Scale. Incident abdominal obesity was defined as waist girth >102 cm. RESULTS Men with low-grade inflammation and depressive symptoms were more likely (OR 4.28, 95% CI 1.93-12.01) to develop abdominal obesity during the 11-year follow-up than in men not having either of these conditions, adjusting for age, smoking, alcohol consumption, prevalent cardiovascular disease, physical activity and socioeconomic status. These men were also more likely (OR 3.94, 95% CI 1.38-11.26) to develop metabolic syndrome. CONCLUSIONS The presence of systemic low-grade inflammation together with depressive symptoms seems to detect men at a particularly high risk of developing abdominal obesity over a long period of time.

Abstract
BACKGROUND Sucrose induces high postprandial glucose and insulin responses. In vitro studies suggest that berries may reduce the digestion and absorption of sucrose and thereby suppress postprandial glycemia, but the evidence in humans is limited. OBJECTIVE We investigated the effects of sucrose ingested with blackcurrants (Ribes nigrum) and lingonberries (Vaccinium vitis-idaea) on postprandial glucose, insulin, and free fatty acid responses. DESIGN Twenty healthy women participated in a randomized, controlled, crossover meal study. They consumed whole blackcurrants or lingonberries (150 g served as purées) or blackcurrant or lingonberry nectars (300 mL), each with 35 g added sucrose. Sucrose alone (35 g in 300 mL water) was used as a reference. Blood samples were collected at 0, 15, 30, 45, 60, 90, and 120 min. RESULTS In comparison with sucrose alone, ingestion of sucrose with whole berries resulted in reduced glucose and insulin concentrations during the first 30 min and a slower decline during the second hour and a significantly improved glycemic profile. Berries prevented the sucrose-induced late postprandial hypoglycemic response and the compensatory free fatty acid rebound. Nearly similar effects were observed when sucrose was consumed with berry nectars. The improved responses were evident despite the higher content of available carbohydrate in the berry and nectar meals, because of the natural sugars present in berries. CONCLUSIONS Blackcurrants and lingonberries, as either whole berries or nectars, optimize the postprandial metabolic responses to sucrose. The responses are consistent with delayed digestion of sucrose and consequent slower absorption of glucose.

Abstract
OBJECTIVE Insulin degludec/insulin aspart (IDegAsp) is a soluble co-formulation of insulin degludec (70%) and insulin aspart (IAsp: 30%). Here, we compare the efficacy and safety of IDegAsp, an alternative IDegAsp formulation (AF: containing 45% IAsp), and biphasic IAsp 30 (BIAsp 30). DESIGN Sixteen-week, open-label, randomised, treat-to-target trial. METHODS Insulin-naive subjects with type 2 diabetes (18-75 years) and a HbA1c of 7-11% were randomised to twice-daily IDegAsp (n=61), AF (n=59) or BIAsp 30 (n=62), all in combination with metformin. Insulin was administered pre-breakfast and dinner (main evening meal) and titrated to pre-breakfast and pre-dinner plasma glucose (PG) targets of 4.0-6.0 mmol/l. RESULTS Mean HbA1c after 16 weeks was comparable for IDegAsp, AF and BIAsp 30 (6.7, 6.6 and 6.7% respectively). With IDegAsp, 67% of subjects achieved HbA1c 7.0% Without confirmed hypoglycaemia in the last 4 weeks of treatment compared with 53% (AF) and 40% (BIAsp 30). Mean fasting PG was significantly lower for IDegAsp vs BIAsp 30 (treatment difference (TD): -0.99 mmol/l (95% confidence interval: -1.68; 0.29)) and AF vs BIAsp 30 (TD: -0.88 mmol/l (-1.58; -0.18)). A significant, 58% lower rate of confirmed hypoglycaemia was found for IDegAsp vs BIAsp 30 (rate ratio (RR): 0.42 (0.23; 0.75)); rates were similar for AF vs BIAsp 30 (RR: 0.92 (0.54; 1.57)). IDegAsp and AF had numerically lower rates of nocturnal confirmed hypoglycaemia vs BIAsp 30 (RR: 0.33 (0.09; 1.14) and 0.66 (0.22; 1.93) respectively). CONCLUSIONS IDegAsp provided comparable overall glycaemic control to BIAsp 30 with a significantly lower rate of hypoglycaemia.

Abstract
BACKGROUND Increased physical activity is a cornerstone of type 2 diabetes prevention. The perception of a need to change is considered essential in behaviour change processes. However, the existing literature on individuals' perceived need to change health behaviour is limited. In order to improve understanding of diabetes prevention through increased physical activity levels (PAL), we assessed factors associated with perceiving a need to increase PAL among adults at high risk of diabetes. METHODS Opportunistic screening was used within a primary-care based lifestyle intervention covering 10 149 men and women at high risk of type 2 diabetes. Data were obtained at baseline visits. The explored determinants were demographic, anthropometric/clinical, behavioural and psychosocial characteristics, along with four categories of PAL awareness. Logistic regression was used in the analysis. RESULTS 74% of men (n = 2 577) and 76% of women (n = 4 551) perceived a need to increase their PAL. The participants most likely to perceive this need were inactive, had a larger waist circumference, rated their PAL as insufficient, and were at the contemplation stage of change. Smoking, elevated blood pressure, dyslipidaemia, and a family history of diabetes were not associated with this perception. The likelihood was also greater among women with less perceived fitness and less education. Demographic factors other than education did not determine participants' perceived need to increase PAL. PAL overestimators were less likely to perceive the need to increase their PAL than realistic inactive participants. CONCLUSIONS Subjective rather than objective health factors appear to determine the perception of a need to increase PAL among adults at high risk of diabetes. Client perceptions need to be evaluated in health counselling in order to facilitate a change in PAL. Practical descriptions of the associations between metabolic risk factors, PAL, and diabetes are needed in order to make the risk factors concrete for at-risk individuals.

Abstract
Individuals with a history of childhood maltreatment present increased rates of metabolic disturbances, but the underlying mechanisms for such phenomena are poorly understood. This study examined whether the secretion of adipokines, adipocyte-derived inflammation markers closely associated with metabolic disorders, is altered in individuals with a history of childhood maltreatment. The serum levels of inflammatory markers adiponectin and resistin were measured from 147 general population participants who had a history of adverse mental symptoms, and who also reported their experiences of childhood maltreatment. Participants with experiences of childhood maltreatment (n=30) had lowered levels of serum adiponectin (p=0.007) and resistin (p=0.028). The differences in adiponectin levels persisted in multivariate modeling with adjustments for age, gender, and body mass index (OR for each 1 standard deviation decrease in the serum adiponectin level 2.65, 95% CI 1.31-5.35, p=0.007). Additional adjustments for marital status or a diagnosis of major depressive disorder, or the exclusion of individuals using NSAIDs, oral corticosteroids, or antidepressants did not alter the results. The association between resistin levels and childhood maltreatment did not remain independent in the same models. Our findings suggest that in individuals with previously reported adverse mental symptoms, a history of childhood maltreatment is independently associated with lowered levels of the anti-inflammatory marker adiponectin. This may lead to a lowered anti-inflammatory buffer capacity, which can, in turn, increase the susceptibility to physical and psychological states characterized by pronounced pro-inflammation.

Abstract
AIM The authors assessed the predictors of success of a lifestyle intervention (weight loss ≥ 5% and improved glucose tolerance) in individuals at high risk for type 2 diabetes in a 1-year follow-up in a primary health care setting. METHODS High-risk individuals for type 2 diabetes were identified by opportunistic screening in the implementation of the Finnish National Diabetes Prevention Program (FIN-D2D). All together, 3880 individuals participated in the 1-year follow-up. Sociodemographic characteristics, health status and behavior, family history of diabetes, clinical factors, and health care provider were considered possible predictors of lifestyle intervention success. RESULTS In sum, 19.3% of individuals lost at least 5% of weight, and 32.6% with abnormal glucose tolerance at baseline showed improvement in glucose tolerance. Abnormal glucose tolerance was the strongest predictor of weight loss and improvement in glucose tolerance. High attendance at lifestyle intervention visits, being outside of labor force, and high body mass index at baseline were also related to weight loss, and high education was related to improvement in glucose tolerance. CONCLUSIONS In "real-life settings," glucose tolerance status, number of intervention visits, employment status, education, and body mass index explained the success of lifestyle intervention. These factors may help in targeting interventions, although they may not be generalized to other cultural settings.

Abstract
OBJECTIVE To assess (i) whether the reporting of counseling previously received is associated with high-risk individuals' agreement to participate in lifestyle intervention, (ii) whether the reporting of previous counseling differed within such a high-risk group, and (iii) the associations between lifestyles and previous lifestyle counseling. METHODS Cross-sectional data were drawn from 10149 adults at high risk of Type 2 diabetes, who were participating in a Finnish national diabetes prevention project (FIN-D2D). Bivariate analysis and multivariate logistic regression were used. RESULTS In relation to the reporting of previous counseling, no difference was found between persons who had agreed and persons who had not agreed to participate in the lifestyle intervention. Persons who were more educated or who had dyslipidemia or diabetes were more likely than the others to report previous counseling. A generally healthy lifestyle, or certain health behaviors (being a non-smoker or eating large amounts of fruit and vegetables) may make the reporting of previous counseling more likely. CONCLUSION The results raise questions about the amount and quality of the previously received lifestyle counseling. PRACTICE IMPLICATIONS There is a need for sustainable lifestyle counseling structures, within vigorously implemented diabetes prevention projects, if long-lasting lifestyle changes are to be achieved.

Abstract
Obesity protects against osteoporosis, but the magnitude of this association has been difficult to assess from cross-sectional or short term studies. We examined the time course of bone loss as a function of body mass index (BMI) in early and late postmenopausal women. Our study population (n = 300) was a random sample of the population-based Kuopio Osteoporosis Risk Factor and Prevention (OSTPRE) Study, Finland. We excluded women without complete BMD results, premenopausal women during the second bone densitometry and women who had used hormone replacement therapy, bisphosphonates or calcitonin. BMI along with femoral neck and spinal bone mineral density (BMD) were assessed three times by dual-energy X-ray absorptiometry during a mean follow-up of 10.5 years (SD 0.5). The mean baseline age was 53.6 years (SD 2.8), time since menopause 2.9 years (SD 4.3) and BMI 27.3 kg/m(2) (SD 4.4). The data was analyzed by linear mixed models. Thus, we were able to approximate the bone loss up to 20 postmenopausal years. To illustrate, a woman with a baseline BMI of 20 kg/m(2) became osteopenic 2 (spine) and 4 (femoral neck) years after menopause, while obesity (BMI of 30 kg/m(2)) delayed the incidence of osteopenia by 5 (spine) and 9 (femoral neck) years, respectively. The delay was due to high baseline BMD of the obese, while bone loss rate was similar for both lean and obese subjects. This lean versus obese difference may also be partly due to altered X-ray attenuation due to fat mass.

BACKGROUND Altered immune responses are seen in depression, and recent data suggest that similar changes could also be observable in alexithymia. We examined whether the inflammatory markers high-sensitivity C-reactive protein (hs-CRP) and interleukin (IL)-6 are independently related to alexithymia or its factors in a population-based sample. METHODS This study formed a clinical part of the Kuopio Depression (KUDEP) general population study focusing on the mental health of a general population of adults aged 25-64 years (n = 308). Alexithymia was measured using the Toronto Alexithymia Scale (TAS-20), and depressive symptoms were assessed using the Beck Depression Inventory (BDI-21). RESULTS The levels of IL-6 (in picograms per milliliter) and hs-CRP (in milligrams per liter) were significantly higher in alexithymic than in nonalexithymic subjects (IL-6 effect size, ES: 0.50; hs-CRP ES: 0.27). The BDI scores, hs-CRP and IL-6 explained 33.5% of the variation in TAS scores in the whole study population. According to logistic regression analysis, hs-CRP but not IL-6 increased the likelihood of belonging to the alexithymic group. This observation remained unaltered after additional adjustments for chronic inflammation-related disorders, the use of inflammation-modulating medications and depressive symptoms. CONCLUSIONS Our findings suggest that the association between hs-CRP and alexithymia resembles that observed in depressed patients. It is, however, independent of depressive symptoms. These findings widen our view on the stress-alexithymia concept.

Abstract
BACKGROUND Inflammatory mediators in both the peripheral circulation and central nervous system (CNS) are dysregulated in major depressive disorder (MDD). Nevertheless, relatively little is known about the role of the T-helper (Th)-2 effector cytokines interleukin (IL)-5 and IL-13 in MDD. METHODS We examined the serum levels of these cytokines and a Th-1 comparison cytokine, interferon (IFN)-γ, in 116 individuals (MDD, n = 58; controls, n = 58). RESULTS In our basic multivariate model controlling for the effects of potential confounders on the associations between MDD and the examined cytokines, each 1-unit increase in the serum IL-5 level increased the likelihood of belonging to the MDD group by 76% (OR 1.76, 95% CI 1.03-2.99, p = 0.04; model covariates: age, gender, marital status, daily smoking and alcohol use). The likelihood further increased in models additionally controlling for the effects of the use of antidepressants and NSAIDS, and a diagnosis of asthma. No such associations were detected with regard to IL-13 (OR 1.08, 95% CI 0.96-1.22, p = 0.22) or IFN-γ (OR 1.02, 95% CI 0.99-1.05, p = 0.23). CONCLUSIONS Elevated levels of IL-5, which uses the neural plasticity-related RAS GTPase-extracellular signal-regulated kinase (Ras-ERK) pathway to mediate its actions in the central nervous system (CNS), could be one of the factors underlying the depression-related changes in CNS plasticity.

Abstract
Current research interest is increasingly directed towards the role of glucocorticoid actions and inflammation. A failure in the stress system regulation appears to largely characterize depression. New research data have substantially diversified the theoretical concept of association between overactivity of HPA-axis and depression. The glucocorticoid effects are regulated by glucocorticoid reseptor gene polymorphisms, and glucocorticoid resistance is often associated with depression. Moreover, immune system disturbances affect the development of depression, and an altered balance of pro- and anti-inflammatory cytokines is also observable. Treatment methods that follow the new developments of the glucocorticoid theory are being developed.

Abstract
Women with a history of gestational diabetes mellitus (GDM) are at increased risk for diabetes mellitus but postpartum followup is problematic for frequent nonattendance. Our aim was to increase coverage of postpartum oral glucose tolerance tests (ppOGTTs) and examine associated factors. This was a prospective observational study of altogether 266 high-risk women for GDM from 2005 to 2008 in four Finnish municipalities. The groups were as follows: women (n = 54) who had previously participated in early pregnancy lifestyle intervention study and high-risk women (n = 102) from the same municipalities studied within one-year after delivery. Furthermore, in two neighboring municipalities nurses were reminded to perform a ppOGTT on high-risk women (n = 110). The primary outcome was the prevalence of ppOGTT performed and associated factors. Overall the ppOGTT was performed in 35.7% of women. Only 14.7% of women returned for testing to health care centers, 30.9% after a reminder in municipalities, and 82.5% to the central hospital, respectively. The most important explaining factor was a special call or reminder from the central hospital (OR 13.4 (4.6-38.1), P < 0.001). Thus, additional reminders improved communication between primary care and secondary care and more attention to postpartum oral glucose testing in primary care are of great importance.

Abstract
Objectives To investigate the association between increase in physical activity and changes in cardiometabolic risk factors during a lifestyle intervention programme in routine clinical settings. Design Prospective follow-up. Setting 400 primary healthcare centres and occupational healthcare outpatient clinics in Finland. Participants Individuals at high risk for type 2 diabetes identified in the implementation project of the national diabetes prevention programme (FIN-D2D) and participating in baseline and 1-year follow-up visits. Final study group comprised the 1871 non-diabetic participants who responded at follow-up visit to a question on stability versus increase of physical activity. Interventions Lifestyle intervention. Primary outcome measures Cardiometabolic risk factors (body composition, blood pressure and those measured from fasting venous blood samples) measured at baseline and follow-up visits. Results Of the participants, 310 (16.6% of all responders) reported at follow-up having clearly increased their physical activity during the past year, while 1380 (73.8%) had been unable to increase their physical activity. Those who increased their activity decreased their weight by 3.6 kg (95% CI 2.9 to 4.3, age and sex adjusted, p<0.001) and waist circumference by 3.6 cm (95% CI 2.9 to 4.3, p<0.001) more than those who did not increase their activity. Similarly, those who increased their physical activity had greater reductions in total cholesterol (group difference in reduction 0.17 mmol/l, 95% CI 0.06 to 0.28, p=0.002), low-density lipoprotein cholesterol (0.16 mmol/l, 95% CI 0.06 to 0.26, p=0.001), low-density lipoprotein/high-density lipoprotein ratio (0.17, 95% CI 0.08 to 0.25, p<0.001) as well as fasting glucose (0.09 mmol/l, 95% CI 0.03 to 0.15, p=0.004) and 2 h glucose levels (0.36 mmol/l, 95% CI 0.17 to 0.55, p=0.023) than those who did not increase their physical activity. Conclusion Increasing physical activity seems to be an important feature of cardiometabolic risk reduction among individuals at high risk for type 2 diabetes participating in preventive interventions in routine clinical settings.

Health economic consequences of reducing salt intake and replacing saturated fat with polyunsaturated fat in the adult Finnish population: estimates based on the FINRISK and FINDIET studies. Eur J Clin Nutr 2011; 65:1148-55. [PMID: 21587284 PMCID: PMC3189582 DOI: 10.1038/ejcn.2011.78] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2010] [Revised: 04/12/2011] [Accepted: 04/12/2011] [Indexed: 01/21/2023]
Abstract
BACKGROUND/OBJECTIVES To predict the health economic consequences of modest reductions in the daily intake of salt (-1.0 g per day) and replacement of saturated fat (SFA, -1.0 energy percent (E%)) with polyunsaturated fat (PUFA, +1.0 E%) in the Finnish population aged 30-74 years. SUBJECTS/METHODS A Markov model with dynamic population structure was constructed to present the natural history of cardiovascular diseases (CVDs) based on the most current information about the age- and sex-specific cardiovascular risk factors, dietary habits and nutrient intake. To predict the undiscounted future health economic consequences of the reduction of dietary salt and SFA, the model results were extrapolated for the years 2010-2030 by replacing the baseline population in the year 2007 with the extrapolated populations from the official Finnish statistics. Finnish costs (€2009, societal perspective) and EQ-5D utilities were obtained from published references. RESULTS During the next 20 years, a population-wide intervention directed at salt intake and dietary fat quality could potentially lead to 8000-13,000 prevented CVD cases among the Finnish adults compared the situation in year 2007. In addition, the reduced incidence of CVDs could gain 26,000-45,000 quality-adjusted life years and save €150-225 million over the same time period. CONCLUSION A modest reduction of salt and replacement of SFA with PUFA in food products can significantly reduce the burden of CVD in the adult Finnish population. This impact may be even larger in the near future due to the ageing of Finnish population.

Abstract
BACKGROUND The aim of this work was to examine the prevalence of different metabolical phenotypes of obesity, and to analyze, by using different risk scores, how the metabolic syndrome (MetS) definition discriminates between unhealthy and healthy metabolic phenotypes in different obesity classes. METHODS The Finnish type 2 diabetes (FIN-D2D) survey, a part of the larger implementation study, was carried out in 2007. The present cross-sectional analysis comprises 2,849 individuals aged 45-74 years. The MetS was defined with the new Harmonization definition. Cardiovascular risk was estimated with the Framingham and SCORE risk scores. Diabetes risk was assessed with the FINDRISK score. Non-alcoholic fatty liver disease (NAFLD) was estimated with the NAFLD score. Participants with and without MetS were classified in different weight categories and analysis of regression models were used to test the linear trend between body mass index (BMI) and various characteristics in individuals with and without MetS; and interaction between BMI and MetS. RESULTS A metabolically healthy but obese phenotype was observed in 9.2% of obese men and in 16.4% of obese women. The MetS-BMI interaction was significant for fasting glucose, 2-hour plasma glucose, fasting plasma insulin and insulin resistance (HOMA-IR)(p < 0.001 for all). The prevalence of total diabetes (detected prior to or during survey) was 37.0% in obese individuals with MetS and 4.3% in obese individuals without MetS (p < 0.001). MetS-BMI interaction was significant (p < 0.001) also for the Framingham 10 year CVD risk score, NAFLD score and estimated liver fat %, indicating greater effect of increasing BMI in participants with MetS compared to participants without MetS. The metabolically healthy but obese individuals had lower 2-hour postload glucose levels (p = 0.0030), lower NAFLD scores (p < 0.001) and lower CVD risk scores (Framingham, p < 0.001; SCORE, p = 0.002) than normal weight individuals with MetS. CONCLUSIONS Undetected Type 2 diabetes was more prevalent among those with MetS irrespective of the BMI class and increasing BMI had a significantly greater effect on estimates of liver fat and future CVD risk among those with MetS compared with participants without MetS. A healthy obese phenotype was associated with a better metabolic profile than observed in normal weight individuals with MetS.

Abstract
CONTEXT The consumption of statins (HMG-CoA reductase inhibitors) in most Western countries has increased to the extent that it may affect all-cause and disease-specific mortality. OBJECTIVE To analyze the association of statin use with all-cause and disease-specific mortality utilizing nationwide databases in a record linkage study in Finland. METHODS The study population included all statin users in Finland who had purchased at least one prescription between 1997 and 2005. A control population matched for age, sex, and place of residence and without statin usage was selected. The study population consisted of 336, 618 pairs of individuals, and the mean length of follow-up was 4.4 years. All-cause mortality and mortality caused by coronary heart disease (CHD), stroke, other circulatory causes, cancer, unnatural causes, and suicide were analyzed. Persistence to treatment was calculated by varying adherence criteria between 20 and 80%. RESULTS We observed association between all-cause, non-CHD and CHD and treatment with statins in statin user group. For CHD mortality, we observed a relationship between the persistence to statin treatment and a decreasing CHD mortality. For each 10% increase in adherence criteria, a 5% (2-8%) decrease in CHD mortality was observed within the range of 20% (RR 0.81, 95%CI 0.32-2.02) to 80% (RR 0.54, 95%CI 0.46-0.64). CONCLUSION In this nationwide study, long-term use of statins is associated with the reduction in CHD mortality.

Abstract
BACKGROUND The aim of this cross-sectional study was to examine the association between serum calcium and the components of metabolic syndrome (MetS). METHODS As a part of the national prevention program of diabetes in Finland (FIN-D2D), a randomly selected study population of 4500 middle-aged men and women were recruited from three central hospital district areas. Anthropometric measurements were performed by a trained nurse. An oral glucose tolerance test was performed and serum calcium and lipids were measured. We assessed current medications, physical activity, smoking, alcohol consumption, calcium intake, and vitamin D intake. The MetS was defined according to the criteria of the updated National Education Program. The study population consisted of 2896 individuals: 1396 men (62% of invited individuals) and 1500 women (66.7% of invited individuals). RESULTS The mean age was 60.3±8.3 years in men and 59.8±8.5 years in women. The prevalence of MetS was 50.7% in women and 55.8% in men. The prevalence of MetS and its components, except high-density lipoprotein (HDL)-cholesterol, increased linearly with increasing serum calcium (P<0.001), even after adjustment for age, physical activity, alcohol, vitamin D intake, calcium intake, and smoking. The threshold value for serum calcium for MetS was 2.50 mmol/l in this population. The association of MetS with total serum calcium was similar even after exclusion of patients treated with hypertensive drugs. The drug treatments for hypertension, dyslipidemia, and diabetes increased in a similar pattern. CONCLUSIONS Serum calcium level is associated with MetS and its components, except HDL-cholesterol.

Abstract
OBJECTIVE In this FIN-D2D cross-sectional survey the relationship of age with HbA(1c) and fasting and 2h glucose in the oral glucose tolerance test (OGTT) was explored in apparently randomly selected healthy population. PATIENTS AND METHODS The glycaemic parameters were measured in 1344 men and 1482 women (aged 45-74 years), and among them we excluded all subjects with known diabetes, hypertension or dyslipidaemia. The final analyses for HbA(1c) and the ratios of fasting glucose/HbA(1c) and 2h glucose/HbA(1c) included 649 men and 804 women. RESULTS Mean age was 57 years and BMI 26.1kg/m(2) for both genders. HbA(1c) increased in both genders with age (p<0.001). For a particular fasting glucose level HbA(1c) level was higher in older age groups (p<0.001 for linearity). By contrast, a particular 2h plasma glucose value in OGTT implied significantly lower HbA(1c) in the elderly (p<0.001 for linearity). CONCLUSION In apparently healthy population, screened with OGTT, in older individuals compared with younger ones a particular HbA(1c) value implies slightly lower fasting glucose, but relatively higher 2h glucose. These results need to be verified in different populations. The effects of age on relation between HbA(1c) and plasma glucose should be taken into account in classifying people into different dysglycaemia categories.
