  • Ingår i: The Journal of clinical endocrinology and metabolism. - : Oxford University Press. - 1945-7197. ; 96, s. 119-124

    • Objective: The minor G allele of FOXO3A rs2802292 has been associated with longevity. We aimed to investigate whether a phenotype related to healthy metabolic aging could be identified in individuals carrying the longevity-associated FOXO3A rs2802292 G allele. Research Design and Methods: rs2802292 was genotyped in a phenotypically well-characterized population of young and elderly twins (n = 190) and in the population-based Inter99 cohort (n = 5768). All participants underwent oral glucose tolerance tests, and the twin population was additionally examined with an iv glucose tolerance test and a hyperinsulinemic, euglycemic clamp. Basal and insulin-stimulated FOXO3A mRNA expression was assessed in skeletal muscle biopsies from the twin population. Results: In the twin sample, carriers of the minor G allele of rs2802292 showed reduced fasting plasma insulin [per allele effect (β) = -13% (-24; -1) (95% confidence interval), P = 0.03] and lower incremental area under the curve 0-120 min for insulin after an oral glucose load [β = -14% (-23; -), P = 0.005]. The G allele was associated with increased peripheral insulin action [glucose disposal rate clamp, β = 0.85 mg·kgfat-free mass(-1) · min(-1) (0.049; 1.64), P = 0.04] and lower hepatic insulin resistance index [β = -13% (-25; -1), P = 0.03]. Furthermore, carriers of the G allele had increased basal FOXO3A mRNA expression in skeletal muscle compared with T-allele carriers [β = 16% (0; 33), P = 0.047]. In the Inter99 sample, we found an association with reduced incremental area under the curve 0-120 min for insulin after an oral glucose load [β = -3% (-5; -0.07), P = 0.04], but this association was not significant after adjustment for body mass index. Conclusion: Our data indicate that the minor G allele of FOXO3A rs2802292 is associated with enhanced peripheral and hepatic insulin sensitivity in our small twin cohort, which may be mediated through increased FOXO3A mRNA expression, although no major metabolic impact of rs2802292 was found in the large Inter99 cohort.

  • The contribution of educational class in improving accuracy of cardiovascular risk prediction across European regions : the MORGAM Project Cohort Component
  • 2014
  • Ingår i: Heart. - : BMJ Publishing Group. - 1355-6037 .- 1468-201X. ; 100:15, s. 1179-1187
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective To assess whether educational class, an index of socioeconomic position, improves the accuracy of the SCORE cardiovascular disease (CVD) risk prediction equation.Methods In a pooled analysis of 68 455 40-64-year-old men and women, free from coronary heart disease at baseline, from 47 prospective population-based cohorts from Nordic countries (Finland, Denmark, Sweden), the UK (Northern Ireland, Scotland), Central Europe (France, Germany, Italy) and Eastern Europe (Lithuania, Poland) and Russia, we assessed improvements in discrimination and in risk classification (net reclassification improvement (NRI)) when education was added to models including the SCORE risk equation.Results The lowest educational class was associated with higher CVD mortality in men (pooled age-adjusted HR=1.64, 95% CI 1.42 to 1.90) and women (HR=1.31, 1.02 to 1.68). In men, the HRs ranged from 1.3 (Central Europe) to 2.1 (Eastern Europe and Russia). After adjustment for the SCORE risk, the association remained statistically significant overall, in the UK and Eastern Europe and Russia. Education significantly improved discrimination in all European regions and classification in Nordic countries (clinical NRI=5.3%) and in Eastern Europe and Russia (NRI=24.7%). In women, after SCORE risk adjustment, the association was not statistically significant, but the reduced number of deaths plays a major role, and the addition of education led to improvements in discrimination and classification in the Nordic countries only.Conclusions We recommend the inclusion of education in SCORE CVD risk equation in men, particularly in Nordic and East European countries, to improve social equity in primary prevention. Weaker evidence for women warrants the need for further investigations.

  • Do other cardiovascular risk factors influence the impact of age on the association between blood pressure and mortality? : The MORGAM Project
  • 2014
  • Ingår i: Journal of Hypertension. - : Ovid Technologies. - 0263-6352 .- 1473-5598. ; 32:5, s. 1025-1033
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To investigate age-related shifts in the relative importance of SBP and DBP as predictors of cardiovascular mortality and all-cause mortality and whether these relations are influenced by other cardiovascular risk factors. Methods: Using 42 cohorts from the MORGAM Project with baseline between 1982 and 1997, 85 772 apparently healthy Europeans and Australians aged 19-78 years were included. During 13.3 years of follow-up, 9.2% died (of whom 7.2% died due to stroke and 21.1% due to coronary heart disease, CHD). Results: Mortality risk was analyzed using hazard ratios per 10-mmHg/5-mmHg increase in SBP/DBP by multivariate-adjusted Cox regressions, including SBP and DBP simultaneously. Because of nonlinearity, SBP and DBP were analyzed separately for blood pressure (BP) values above and below a cut-point wherein mortality risk was the lowest. For the total population, significantly positive associations were found between stroke mortality and SBP [hazard ratio = 1.19 (1.13-1.25)] and DBP at least 78 mmHg [hazard ratio = 1.08 (1.02-1.14)], CHD mortality and SBP at least 116 mmHg [1.20 (1.16-1.24)], and all-cause mortality and SBP at least 120 mmHg [1.09 (1.08-1.11)] and DBP at least 82 mmHg [1.03 (1.02-1.05)]. BP values below the cut-points were inversely related to mortality risk. Taking into account the age x BP interaction, there was a gradual shift from DBP (19-26 years) to both DBP and SBP (27-62 years) and to SBP (63-78 years) as risk factors for stroke mortality and all-cause mortality, but not CHD mortality. The age at which the importance of SBP exceeded DBP was for stroke mortality influenced by sex, cholesterol, and country risk. Conclusion: Age-related shifts to the superiority of SBP exist for stroke mortality and all-cause mortality, and for stroke mortality was this shift influenced by other cardiovascular risk factors.

  • Impact of Age and Gender on the Prevalence and Prognostic Importance of the Metabolic Syndrome and Its Components in Europeans. The MORGAM Prospective Cohort Project
  • 2014
  • Ingår i: PLOS ONE. - 1932-6203. ; 9:9, s. e107294-
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: To investigate the influence of age and gender on the prevalence and cardiovascular disease (CVD) risk in Europeans presenting with the Metabolic Syndrome (MetS). Methods: Using 36 cohorts from the MORGAM-Project with baseline between 1982-1997, 69094 men and women aged 19-78 years, without known CVD, were included. During 12.2 years of follow-up, 3.7%/2.1% of men/women died due to CVD. The corresponding percentages for fatal and nonfatal coronary heart disease (CHD) and stroke were 8.3/3.8 and 3.1/2.5. Results: The prevalence of MetS, according to modified definitions of the International Diabetes Federation (IDF) and the revised National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII), increased across age groups for both genders (P<0.0001); with a 5-fold increase in women from ages 19-39 years to 60-78 years (7.4%/7.6% to 35.4%/37.6% for IDF/NCEP-ATPIII) and a 2-fold increase in men (5.3%/10.5% to 11.5%/21.8%). Using multivariate-adjusted Cox regressions, the associations between MetS and all three CVD events were significant (P<0.0001). For IDF/NCEP-ATPIII in men and women, hazard ratio (HR) for CHD was 1.60/1.62 and 1.93/2.03, for CVD mortality 1.73/1.65 and 1.77/2.06, and for stroke 1.51/1.53 and 1.58/1.77. Whereas in men the HRs for CVD events were independent of age (MetS*age, P>0.05), in women the HRs for CHD declined with age (HRs 3.23/3.98 to 1.55/1.56; MetS*age, P = 0.01/P = 0.001 for IDF/NCEP-ATPIII) while the HRs for stroke tended to increase (HRs 1.31/1.25 to 1.55/1.83; MetS*age, P>0.05). Conclusion: In Europeans, both age and gender influenced the prevalence of MetS and its prognostic significance. The present results emphasise the importance of being critical of MetS in its current form as a marker of CVD especially in women, and advocate for a redefinition of MetS taking into account age especially in women.
