- The rapid increase of coronary heart disease mortality in Northern Norway during 1951-1970 was why the newly established University of TromsO decided to start a study to identify major operating cardiovascular risk factors. The first TromsO survey in 1974 suggested that the relatively high cardiovascular mortality was associated with elevated cholesterol levels and high prevalence of smoking, while high-density-lipoprotein-cholesterol (HDL-C) was identified as a preventive factor. After 1974, six more surveys including both genders (aged 20-89 years) were undertaken. The second survey (1979) revealed the cholesterol increasing effect of coffee. Echocardiographic examinations, ECG, and ultrasound of carotid arteries were introduced in later surveys, and intervention studies were established. Repeated carotid measurements showed that inflammation was involved in novel plaque formation, while HDL-C was protective. Moderate physical activity protected against atrial fibrillation but hard exercise increased the risk. Obesity, hypertension and smoking increased the risk of aortic stenosis, and diastolic dysfunction predicted development of atrial fibrillation. Dilated left atria predicted stroke, especially for individuals without known atrial fibrillation. Total cholesterol, blood pressure and smoking declined after 1974, corresponding to the subsequent decline in coronary heart disease mortality. Reduced incidence accounted for 40% of the mortality decline, while a substantial reduction in case fatality explained the remaining 60%.

- Department of Occupational and Environmental Medicine, Sahlgrenska University Hospital, SE 405 30 Göteborg, Sweden. Anna-Carin.Olin@amm.gu.se STUDY OBJECTIVES: The fraction of exhaled nitric oxide (Feno) is elevated in subjects with asthma and atopy, and it has been proposed to be a noninvasive marker of airway inflammation. In addition to asthma and atopy, there is limited information about the determinants of Feno in a general population. DESIGN: Cross-sectional. SETTING: A random adult general population sample. PARTICIPANTS: A total of 2,200 subjects, 1,111 women and 1,089 men, aged 25 to 75 years. INTERVENTIONS: The subjects were examined with regard to Feno, pulmonary function, anthropometric variables, and blood samples for Ig E, and completed a respiratory questionnaire. The associations between different determinants and Feno were analyzed with multiple linear regression models. RESULTS: The median value of Feno was 16.0 parts per billion (ppb), ranging from 2.4 to 199 ppb. Height, age, atopy, reporting of asthma symptoms in the last month, and reported use of inhaled steroids were positively associated with Feno. Current smokers had lower values of Feno. Gender was not associated with Feno. CONCLUSIONS: In this random adult population sample, height, but not gender, was associated with Feno. Furthermore, asthma symptoms in the last month, reported use of inhaled steroids, and atopy were positively and independently associated with Feno, while there was a negative association with smoking.

- RATIONALE: Fraction of exhaled nitric oxide (Fe(NO)) is regarded as a marker of airway inflammation. It is unknown whether increased Fe(NO) in respiratorily healthy subjects increases the risk of developing wheeze. OBJECTIVES: To examine if increased levels of Fe(NO) predicts later onset of wheeze. METHODS: We followed up 2,200 men and women from a general population-based study. At baseline, the subjects were investigated with questionnaires, blood samples, pulmonary function tests, and Fe(NO). At follow-up 4 years later, all subjects were mailed a respiratory questionnaire. The association between incident wheeze and baseline levels of Fe(NO) over the 90th percentile were evaluated calculating hazard ratios using Cox regression models adjusted for smoking habits, age, height, sex, and atopy. MEASUREMENTS AND MAIN RESULTS: The follow-up questionnaire was completed by 1,896 subjects (86.2%). All subjects reporting wheeze, asthma, or asthma symptoms at baseline were excluded resulting in a study population of 1,506 subjects. Of these, 49 subjects reported new-onset wheeze. The median concentration of Fe(NO) at baseline was significantly higher among those with new-onset wheeze (18.8 ppb vs. 15.8 ppb, P = 0.03). In a Cox regression model including all subjects, Fe(NO) over the 90th percentile predicted onset of wheeze (hazard ratio 2.7; 95% confidence interval, 1.4-5.4). In stratified models, this was most apparent among never-smokers and in atopic subjects, for whom the odds ratios were higher. CONCLUSIONS: Our results indicate that increased Fe(NO) is associated with an increased risk of developing wheeze. The results also support the hypothesis that increased level of Fe(NO) among subjects without respiratory symptoms is a sign of subclinical airways inflammation.

- Zn-alpha2-glycoprotein (ZAG) is a serum protein implicated in cancer cachexia and lipolysis. Our aim was to investigate serum levels of ZAG and polymorphisms in the ZAG gene in relation to serum lipids in man. Serum levels of ZAG correlated with serum levels of cholesterol (P = .00088) in healthy subjects and during weight loss (P = .059). The ZAG genotype was associated with total cholesterol (P = .014) and low-density lipoprotein cholesterol (P = .026) in healthy subjects, and the associations were replicated in an additional cohort (P = .0017 and P = .060, respectively). Our data indicate that ZAG plays a role in lipid metabolism.

- Apolipoprotein C-I (apoCI) is implicated in lipid metabolism and inflammatory response, both important risk factors for human heart disease. However, most findings come from in vitro or animal studies, whereas data on human apoCI are sparse. To elucidate the role of apoCI in human disease, we analyzed a functional polymorphism in the promoter region of the apoCI gene in relation to blood lipids, C-reactive protein (CRP), coronary artery disease (CAD), and myocardial infarction (MI). Rs11568822 is a 4-base pair insertion/deletion (Ins/Del) polymorphism, and the Ins allele leads to a higher transcription in vitro compared with the Del allele. This polymorphism was analyzed in the Intergene study, a case-control study for CAD (N = 1236), and the Stockholm Heart Epidemiology Program, a case-control study for MI (N = 2774). Subjects homozygous for the Ins genotype had significantly higher serum levels of triglycerides (P = .01 and P = .006) and lower serum levels of CRP (P = .02 and P < .0001) compared with all other subjects in both studies. Similar results were obtained when analyzing only the controls of both studies (P = .002 and P = .0002, triglycerides; P = .002 and P < .0001, CRP). However, apoCI was not associated with CAD or MI. In conclusion, our data show that apoCI genotype is associated with serum levels of triglycerides and CRP, confirming the role of apoCI in lipid metabolism and suggesting that it also influences inflammation.

- The selenoprotein S (SELS) is a putative receptor for serum amyloid A, and recent studies have suggested that SELS may be a link between type 2 diabetes mellitus and inflammation. Genetic studies of SELS polymorphisms have revealed associations with circulating levels of inflammatory markers and hard end points of cardiovascular disease. In this study, we analyzed SELS expression in subcutaneous adipose tissue and SELS genotype in relation to metabolic risk factors. DNA microarray expression analysis was used to study the expression of SELS in lean and obese siblings from the Swedish Obese Subjects Sib Pair Study. TaqMan genotyping was used to analyze 3 polymorphisms, previously found to be associated with circulating levels of inflammatory markers, in the INTERGENE case-control study of myocardial infarction and unstable angina pectoris. Possible associations between SELS genotype and/or expression with anthropometry and measures of metabolic status were investigated. Real-time polymerase chain reaction was used to analyze the SELS expression in isolated human adipocytes incubated with insulin. In lean subjects, we found correlations between SELS gene expression in subcutaneous adipose tissue and measures of obesity (waist, P = .045; sagittal diameter, P = .031) and blood pressure (diastolic, P = .016; systolic P = .015); and in obese subjects, we found correlations with measures of obesity (body mass index, P = .03; sagittal diameter, P = .008) and glycemic control (homeostasis model assessment of insulin resistance, P = .011; insulin, P = .009) after adjusting for age and sex. The 5227GG genotype was associated with serum levels of insulin (P = .006) and homeostasis model assessment of insulin resistance (P = .007). The expression of SELS increased after insulin stimulation in isolated human adipocytes (P = .008). In this study, we found an association between both SELS gene expression in adipose tissue and SELS genotype with measures of glycemic control. In vitro studies demonstrated that the SELS gene is regulated by insulin in human subcutaneous adipocytes. This study further supports a role for SELS in the development of metabolic disease, especially in the context of insulin resistance.

- OBJECTIVES: To examine the long-term incidence of diabetes in relation to coffee consumption in Swedish women. DESIGN: Prospective longitudinal cohort study. SETTING: City of Goteborg, Sweden. SUBJECTS: A random population sample of 1361 women, aged 39-65 years, without prior diabetes or cardiovascular disease took part in a screening study in 1979-1981 with questionnaires, physical examination and blood sampling. MAIN OUTCOME MEASURES: The development of diabetes until 1999 was identified by questionnaires in a second screening and the Swedish hospital discharge register. RESULTS: Altogether, there were 74 new cases of diabetes. The risk of developing diabetes was 475 per 100 000 person-years in women who consumed two cups of coffee or less per day, 271 in women who consumed three to four cups per day, 202 with a consumption of five to six cups per day, and 267 in drinkers of seven cups or more per day. Associated hazard ratios, after adjustment for age, smoking, low physical activity, education and body mass index were 0.55 (0.32-0.95), 0.39 (0.20-0.77) and 0.48 (0.22-1.06) for daily consumption of three to four, five to six and seven cups or more, respectively, with a consumption of less than two per day as reference. Additional adjustment for serum cholesterol and triglycerides attenuated the relation between coffee and diabetes slightly, indicating a possible mediating effect on the effect of coffee by serum lipids. CONCLUSIONS: The findings of the present study support the hypothesis that coffee consumption protects from the development of diabetes in women.

- BACKGROUND: The individual physical activity level is an independent risk factor for cardiovascular disease and death, as well as a possible target for improving health outcome. However, today's widely adopted risk score charts, typically do not include the level of physical activity. There is a need for a simple risk assessment tool, which includes a reliable assessment of the level of physical activity. The aim of this study was therefore, to analyse the association between the self-reported levels of physical activity, according to the Saltin-Grimby Physical Activity Level Scale (SGPALS) questionnaire, and cardiovascular risk factors, specifically focusing on the group of individuals with the lowest level of self-reported PA.METHODS: We used cross sectional data from the Intergene study, a random sample of inhabitants from the western part of Sweden, totalling 3588 (1685 men and 1903 women, mean age 52 and 51). Metabolic measurements, including serum-cholesterol, serum-triglycerides, fasting plasma-glucose, waist circumference, blood pressure and resting heart rate, as well as smoking and self-reported stress were related to the self-reported physical activity level, according to the modernized version of the SGPALS 4-level scale.RESULTS: There was a strong negative association between the self-reported physical activity level, and smoking, weight, waist circumference, resting heart rate, as well as to the levels of fasting plasma-glucose, serum-triglycerides, low-density lipoproteins (LDL), and self-reported stress and a positive association with the levels of high-density lipoproteins (HDL). The individuals reporting the lowest level of PA (SGPALS, level 1) had the highest odds-ratios (OR) for having pre-defined levels of abnormal risk factors, such as being overweight (men OR 2.19, 95% CI: 1.51-3.19; women OR 2.57, 95 % CI: 1.78-3.73), having an increased waist circumference (men OR 3.76, 95 % CI: 2.61-5.43; women OR 2.91, 95% CI: 1.94-4.35) and for reporting stress (men OR 3.59, 95 % CI: 2.34-5.49; women OR 1.25, 95% CI: 0.79-1.98), compared to the most active individuals, but also showed increased OR for most other risk factors analyzed above.CONCLUSION: The self-reported PA-level according to the modernized Saltin-Grimby Physical Activity Level Scale, SGPALS, is associated with the presence of many cardiovascular risk factors, with the most inactive individuals having the highest risk factor profile, including self-reported stress. We propose that the present SGPALS may be used as an additional, simple tool in a routine risk assessment in e.g. primary care, to identify inactive individuals, with a higher risk profile.

- While prevalence estimates differ by definition of metabolic syndrome (MetS), it is less clear how different definitions affect associations with alcohol consumption.We included 3051 adults aged 25-77 from the baseline examination of the Swedish INTERGENE cohort (2001-2004). Using multiple logistic regression, we investigated cross-sectional associations between ethanol intake and MetS defined according to the Adult Treatment Panel III (ATP III), the International Diabetes Federation (IDF), and the Joint Interim Statement (JIS). Alcohol exposure categories comprised abstinence, and low, medium, and high consumption defined via sex-specific tertiles of ethanol intake among current consumers. Covariates included sociodemographics, health, and lifestyle factors.MetS prevalence estimates varied between 13.9% (ATP III) and 25.3% (JIS), with higher prevalence in men than women. Adjusted for age and sex, medium-high alcohol consumption was associated with lower odds of MetS compared to low consumption, while no difference was observed for abstainers. Only the most specific (and thus severe) definition of MetS (ATP III) showed decreasing odds for ethanol intake when adjusted for all covariates.Our study shows that alcohol-related associations differ by definition of MetS. The finding that individuals with the most stringently defined MetS may benefit from alcohol consumption calls for further well-controlled studies.
