Polymorphisms Related to the Serum 25-Hydroxyvitamin D Level and Risk of Myocardial Infarction, Diabetes, Cancer and Mortality. The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
Low serum 25(OH)D levels are associated with cardiovascular risk factors, and also predict future myocardial infarction (MI), type 2 diabetes (T2DM), cancer and all-cause mortality. Recently several single nucleotide polymorphisms (SNPs) associated with serum 25-hydroxyvitamin D (25(OH)D) level have been identified. If these relations are causal one would expect a similar association between these ...
Genetic variations in the Vitamin D receptor predict type 2 diabetes and myocardial infarction in a community-based population: The tromsø study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-12-23)
Background
Though the associations between low serum 25-hydroxyvitamin D (25(OH)D) levels and
health outcomes such as type 2 diabetes (T2D), myocardial infarction (MI), cancer, and
mortality are well-studied, the effect of supplementation with vitamin D is uncertain. This
may be related to genetic differences. Thus, rs7968585, a single nucleotide polymorphism
(SNP) of the vitamin D receptor ...
The phosphodiesterase 8B gene rs4704397 is associated with thyroid function, risk of myocardial infarction and body height. The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
Objective: High serum thyrotropin (TSH) levels predict cardiovascular disease (CVD). Recently several single
nucleotide polymorphisms (SNPs) associated with TSH levels have been identified, one of them being the
rs4704397 SNP in the phosphodiesterase 8B (PDE8B) gene. If the relation between thyroid function and CVD is
causal, one could also expect rs4704397 genotypes to predict CVD and possibly ...
Effects of Age and Sex on Estimated Diabetes Prevalence Using Different Diagnostic Criteria: The Tromso OGTT Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
Hb 6.5% has recently been recommended as an alternative diagnostic criterion for diabetes. The aims of the study were to evaluate the effects of age, sex, and other factors on prevalence of diabetes and to compare risk profiles of subjects with diabetes when defined by Hb and glucose criteria. Subjects were recruited among participants in the longitudinal population-based Tromsø Study. Hb , fasting ...
Effect of genetically low 25-hydroxyvitamin D on mortality risk: Mendelian randomization analysis in 3 large European cohorts
(Journal article; Tidsskriftartikkel; Peer reviewed, 2019-01-02)
The aim of this study was to determine if increased mortality associated with low levels of serum 25-hydroxyvitamin D (25(OH)D) reflects a causal relationship by using a Mendelian randomisation (MR) approach with genetic variants in the vitamin D synthesis pathway. Individual participant data from three European cohorts were harmonized with standardization of 25(OH)D according to the Vitamin D ...
Hyperglycemia, Assessed by HbA1c, and Future Risk of Venous Thromboembolism - The Tromsø Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-03-05)
Background: Glycated hemoglobin (HbA1c), a marker of average plasma glucose
during the last 8-12 weeks, is associated with future risk of cardiovascular disease
(CVD) and all-cause mortality.
Objectives: To examine the association between hyperglycemia, assessed by
HbA1c, and future risk of VTE in a population based cohort.
Methods: HbA1c was measured in 16 156 unique subjects (25-87 years) ...
Vitamin D and mortality: Individual participant data meta-analysis of standardized 25-hydroxyvitamin D in 26916 individuals from a European consortium
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-16)
Background:<br>Vitamin D deficiency may be a risk factor for mortality but previous meta-analyses lacked standardization of laboratory methods for 25-hydroxyvitamin D (25[OH]D) concentrations and used aggregate data instead of individual participant data (IPD). We therefore performed an IPD meta-analysis on the association between standardized serum 25(OH)D and mortality.<br>Methods:<br>In a European ...
Vitamin D and mortality: meta-analysis of individual participant data from a large consortium of cohort studies from Europe and the United States
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-06-17)
Objective To investigate the association between serum 25-hydroxyvitamin D concentrations (25(OH)D) and mortality in a large consortium of cohort studies paying particular attention to potential age, sex, season, and country differences.<p>
<p>Design Meta-analysis of individual participant data of eight prospective cohort studies from Europe and the US.
<p>Setting General population.
