- The aim of this study is to evaluate if two different physical activity (PA) questionnaires have similar ability to rank individuals, and to examine associations with cardiovascular-metabolic risk factors, compared to an objective measure. In a random sample (n=369, age: 65+/-6 years) from the population-based 'Malmö Diet and Cancer' (MDC) cohort, PA was measured by a leisure-time comprehensive questionnaire (MDC-score), a simple leisure-time questionnaire and by accelerometer-monitoring (CSA). Moderate correlations were observed between MDC-score and CSA in men and women (r=0.35 and 0.24, respectively). In men, both questionnaires and CSA were inversely associated with waist circumference, insulin resistance and metabolic syndrome. In women, the MDC-score was positively associated with high-density lipoprotein-cholesterol, and the simple questionnaire inversely associated with anthropometric indexes, but no association was seen between PA estimates and cardiovascular components. We conclude that both PA questionnaires distinguish health risks associated with anthropometric-metabolic risk factors, particularly in men.European Journal of Clinical Nutrition advance online publication, 29 July 2009; doi:10.1038/ejcn.2009.69.

- Elevated blood pressure is a common, heritable cause of cardiovascular disease worldwide. To date, identification of common genetic variants influencing blood pressure has proven challenging. We tested 2.5 million genotyped and imputed SNPs for association with systolic and diastolic blood pressure in 34,433 subjects of European ancestry from the Global BPgen consortium and followed up findings with direct genotyping (N <= 71,225 European ancestry, N <= 12,889 Indian Asian ancestry) and in silico comparison (CHARGE consortium, N 29,136). We identified association between systolic or diastolic blood pressure and common variants in eight regions near the CYP17A1 (P = 7 x 10(-24)), CYP1A2 (P = 1 x 10(-23)), FGF5 (P = 1 x 10(-21)), SH2B3 (P = 3 x 10(-18)), MTHFR (P = 2 x 10(-13)), c10orf107 (P = 1 x 10(-9)), ZNF652 (P = 5 x 10(-9)) and PLCD3 (P = 1 x 10(-8)) genes. All variants associated with continuous blood pressure were associated with dichotomous hypertension. These associations between common variants and blood pressure and hypertension offer mechanistic insights into the regulation of blood pressure and may point to novel targets for interventions to prevent cardiovascular disease.

Tidskriftsartikel (refereegranskat)abstract
- Background: Based on a large, representative unscreened cohort from Malmo, Sweden, we have recently reported that a single prostate-specific antigen (PSA) measurement at or before age 50 is a strong predictor of prostate cancer occurring up to 25 years subsequently. We aimed to determine whether this association holds for advanced cancers, defined as clinical stage T3 or higher, or skeletal metastasis at the time of the cancer diagnosis. Methods: In 1974-1986 blood samples were obtained from a cohort of 21,277 men aged up to 50. Through 1999, 498 men were diagnosed with prostate cancer, and of these 161 had locally advanced or metastatic prostate cancers. Three controls, matched for age and date of venipuncture, were selected for each case. Conditional logistic regression was used to test associations between molecular markers and advanced cancer. Results: Median time from venipuncture to diagnosis was 17 years. Levels of all PSA forms and hK2 were associated with case status. Total PSA was a strong and statistically significant predictor of subsequent advanced cancer ( area under the curve 0.791; p < 0.0005). Two-thirds of the advanced cancer cases occurred in men with the top 20% of PSA levels (0.9 ng/ml or higher). Conclusion: A single PSA test taken at or before age 50 is a very strong predictor of advanced prostate cancer diagnosed up to 25 years later. This suggests the possibility of using an early PSA test to risk-stratify patients so that men at highest risk are the focus of the most intensive screening efforts.

- BACKGROUND: Male arginine vasopressin 1a receptor knockout mice (V1aR(-/-)) display a phenotype of low triglycerides and high glucose concentrations and high-fat-diet-induced obesity and diabetes. OBJECTIVE: We investigated whether genetic variation of the human arginine vasopressin 1A (AVPR1A) gene is associated with phenotypic features resembling those of the V1aR(-/-) mouse. DESIGN: In a population-based cross-sectional study in southern Sweden, middle-aged individuals (n = 6055) were examined in 1991-1994. Associations between 4 AVPR1A tag single nucleotide polymorphisms (rs1042615, rs10784339, rs7308855, and rs10747983) and diabetes status, glucose and triglyceride concentrations, and BMI were analyzed. Furthermore, rs1042615 was related to diabetes status, glucose, and triglycerides within sex-specific quartiles of dietary fat intake (Q1(Fat)-Q4(Fat)) and BMI (Q1(BMI)-Q4(BMI)). RESULTS: Subjects carrying the T allele of rs1042615 had lower concentrations of triglycerides than did CC carriers (1.36 +/- 0.77 compared with 1.42 +/- 0.89 mmol/L; P = 0.014), especially in nondiabetic subjects (P = 0.001). Carriers of the rs1042615 T allele had higher fasting blood glucose (5.20 +/- 1.44 mmol/L compared with 5.12 +/- 1.22 mmol/L; P = 0.036) and a tendency toward an increased prevalence of diabetes (odds ratio: 1.22; 95% CI: 0.99, 1.51; P = 0.067) compared with CC carriers. The less common rs10784339, rs7308855, and rs10747983 were not consistently associated with metabolic variables. Among men, the rs1042615 T allele was associated with diabetes exclusively within Q4(Fat) (odds ratio: 2.22; 95% CI: 1.05, 4.71; P = 0.04) and Q4(BMI) (odds ratio: 1.81; 95% CI: 1.11, 2.93; P = 0.02). CONCLUSION: The rs1042615 T allele is associated with features resembling the phenotype of the V1aR(-/-) mouse, including uncoupling of the usual direct relation between glucose and triglycerides and an increased prevalence of diabetes in subjects with a high fat intake or who are overweight.

- Objective. Insulin resistance is associated with progression of atherosclerosis. We assessed the effect of 12 months of treatment with rosiglitazone (RSG) on the progression of carotid intima-media thickness (IMT) in people with type 2 diabetes mellitus (T2DM) or the insulin resistance syndrome (IRS). Design. Randomized, double-blind, placebo-controlled trial. Setting. Malmo University Hospital, Malmo, Sweden. Subjects. 555 subjects (200 with T2DM and 355 nondiabetics with IRS according to EGIR criteria), aged 35-80 years. 447 subjects (165 T2DM and 282 IRS) completed the study. Intervention. Participants were allocated to placebo or RSG 4 mg for 2 months and then 8 mg daily. Main outcome measure. Change in composite IMT [mean IMT in the common carotid artery (CCA) and maximal IMT in the bulb] was the primary and various other IMT measures were secondary outcome variables. Results. There was no effect of RSG treatment in the mixed population. In T2DM patients there was a reduced progression of the composite IMT (mean change: 0.041 vs. 0.070 mm, P = 0.07), and of the mean IMT CCA (mean change: -0.005 mm vs. 0.021 mm, P = 0.007). RSG treatment led to significant reductions of HOMA-IR, fasting plasma glucose, HbA1c, PAI-1 activity, fibrinogen, C-reactive protein and matrix metalloproteinase-9. Conclusions. In a mixed study population of patients with T2DM and IRS RSG treatment was not associated with a statistically significant reduction of carotid IMT progression rate. Separate analyses of these two patient groups indicated, however, a significant beneficial effect on CCA IMT in T2DM patients but no similar effect in subjects with IRS.

- Background:Approximately 10-20% of stroke cases have normal blood pressure (BP). The objective of this study was to explore whether the risk of ischemic stroke is related to the carotid intima-media thickness (CIMT) and atherosclerotic lesions in a cohort of subjects with normal BP. Methods:Common CIMT and the presence of carotid plaque were determined by B-mode ultrasound in 6,103 subjects, randomly recruited between 1991 and 1994 from the 'Malmo Diet and Cancer' study. Normal BP was defined as BP <140/90 mm Hg, without pharmacological treatment for hypertension. Carotid artery atherosclerosis (CAA) was defined as CIMT >/=0.81 mm or/and the presence of plaque (i.e. focal CIMT >1.2 mm). The incidence of ischemic stroke was followed over a mean period of 10.7 years. Results:A total of 2,228 subjects (791 men and 1,437 women) had normal BP. During the follow-up, 34 patients suffered a first-ever ischemic stroke (crude incidence: 1.51/1,000 person-years). The Prevalences of CAA in subjects with and without stroke were 68.6 and 39.0%, respectively. It was estimated that the subjects with CAA had a 3-fold higher risk of ischemic stroke (RR: 3.33, 1.37-8.14), independent of other cardiovascular risk factors. Each increase of 1 standard deviation (0.13 mm) in CIMT increased the stroke risk by 43% (RR: 1.43, 1.002-2.02). Several factors were found to have a notable relation with CAA, including age, male sex, smoking, diabetes, systolic BP, HbA1c (glycosylated hemoglobin) and cholesterol. Conclusions: CIMT and atherosclerotic lesions are independent clinical markers for ischemic stroke among normotensive individuals.

- Aims To calculate the population-attributable risk (PAR) of coronary events (CE) from 10 risk factors, during long-term follow-up. Methods We used both case-cohort and case-control analyses for calculation of PAR in relation to 10 baseline risk factors. First CE (fatal or nonfatal, n = 3072) in 22 444 males and 10 902 females was recorded during a mean follow-up of 20 years by use of national registers. Results Using a Cox regression analysis in a case-cohort design, smoking (prevalence in men 49%, women 37%) was the strongest risk factor, RR 2.29 (95% CI 2.09-2.52; PAR 39%), followed by hypercholesterolaemia, RR 1.70 (95% CI 1.56-1.86; PAR 18%), and diabetes, RR 1.67 (95% CI 1.41-1.99; PAR 3%). For women the strongest risk factors were smoking, RR 3.16 (95% CI 2.50-3.98; PAR 44%), diabetes, RR 2.59 (95% CI 1.78-3.76; PAR 6%), and hypertension, RR 2.47 (95% CI 1.94-3.14; PAR 23%). In men, smoking was the strongest predictor both after 10 years [RR 2.69 (95% CI 2.23-3.24)] and 20 years [RR 2.45 (95% CI 2.15-2.79)], followed by hypercholesterolaemia (RR 2.16-1.63), hypertension (RR 2.04-1.51), and diabetes (RR 1.85 -1.47). The case-control design gave very similar results. Total PAR varied from 74% (fully adjusted Cox regression, case-control, in men) to 116% in women (case-cohort). Conclusion Smoking is the most important long-term risk factor for CE in both genders, based on data from a population with a high proportion of smokers. Ten measured variables explained almost all variation in risk and could be used as a basis for intervention programmes.
