Low serum 25-hydroxyvitamin D (25(OH)D) levels are associated with risk factors for cardiovascular disease, and they also appear to predict later development of type 2 diabetes, cancer, and an increased mortality rate. These predictions are all based on a single 25(OH)D measurement, but so far there are no known reports on tracking of serum 25(OH)D levels. In the present Norwegian study, serum 25(OH)D levels were measured 1) in 2,668 subjects in the 1994 and 2008 Tromsø surveys and 2) every… Expand
Factors Associated With Change in 25-Hydroxyvitamin D Levels Over Longitudinal Follow-Up in the ARIC Study.
TLDR
Overall, increases in 25(OH)D levels over time was associated with male gender, use of vitamin D supplements, greater physical activity, and higher high-density lipoprotein-cholesterol (P < .001). Expand
Tracking of serum 25-hydroxyvitamin D during 21 years
TLDR
There was significant tracking of serum 25(OH)D over the 21 years period between the surveys of the Tromsø study, and the use of a single serum 25-hydroxyvitamin D measurement as an indicator of the vitamin-D status is questionable if used in long-lasting observational studies. Expand
Serum 25-Hydroxyvitamin D Concentration and Risk for Major Clinical Disease Events in a Community-Based Population of Older Adults
TLDR
Threshold concentrations of 25-hydroxyvitamin D associated with increased risk for relevant clinical disease events center near 50 nmol/L (20 ng/mL), suggesting season-specific targets for 25-(OH)D concentration may be more appropriate than static targets when evaluating health risk. Expand
Estimating mean annual 25-hydroxyvitamin D concentrations from single measurements: the Multi-Ethnic Study of Atherosclerosis.
TLDR
Cross-sectional data can be used to estimate subject-specific mean annual 25(OH)D concentrations from single values by using a cosinor model and the tool developed by using this approach may assist research and clinical care of adults in North America by reducing the misclassification of 25( OH)D deficiency. Expand
Cross-sectional and prospective cohort study of serum 25-hydroxyvitamin D level and obesity in adults: the HUNT study.
Experimental studies suggest that vitamin D modulates the activity of adipocytes. The authors examined baseline serum 25-hydroxyvitamin D (25(OH)D) level in relation to prevalent and cumulativeExpand
Low serum 25-hydroxyvitamin D is associated with increased risk of the development of the metabolic syndrome at five years: results from a national, population-based prospective study (The Australian Diabetes, Obesity and Lifestyle Study: AusDiab).
TLDR
In Australian adults, lower 25(OH)D concentrations were associated with increased MetS risk and higher WC, serum triglyceride, fasting glucose, and insulin resistance at 5 yr, and Vitamin D supplementation studies are required to establish whether the link between vitamin D deficiency and MetS is causal. Expand
Reproducibility of serum 25-hydroxyvitamin d and vitamin D-binding protein levels over time in a prospective cohort study of black and white adults.
TLDR
It is suggested that single, baseline 25(OH)D and VDBP serum measurements provide reasonably representative measures of these compounds for both white and black adults, demonstrating their utility as epidemiologic biomarkers in prospective studies. Expand
Strong associations of 25-hydroxyvitamin D concentrations with all-cause, cardiovascular, cancer, and respiratory disease mortality in a large cohort study.
TLDR
In this large cohort study, serum 25(OH)D concentrations were inversely associated with all-cause and cause-specific mortality, and vitamin D deficiency was strongly associated with mortality from all causes, cardiovascular diseases, cancer, and respiratory diseases. Expand
Changes in vitamin D supplement use and baseline plasma 25-hydroxyvitamin D concentration predict 5-y change in concentration in postmenopausal women.
TLDR
The results confirm the importance of supplementation in increasing 25(OH)D concentrations in aging women, even after other statistically significant predictors are controlled for and suggest that this is especially true among aging women with inadequate 25( OH)D. Expand
Seasonal variation in 25-hydroxyvitamin D concentrations in the cardiovascular health study.
TLDR
Serum 25(OH)D varies in a sinusoidal manner, with large seasonal differences relative to mean concentration and laboratory evidence of biologic sequelae. Expand

25-Hydroxyvitamin D Levels and the Risk of Mortality in the General Population
TLDR
Low levels of 25(OH)D (≤17.8 ng/ml) are associated with a higher risk of all-cause mortality in the general US population, and to the authors' knowledge, this is the first study to evaluate this association. Expand
Independent association of low serum 25-hydroxyvitamin d and 1,25-dihydroxyvitamin d levels with all-cause and cardiovascular mortality.
TLDR
Low 25-hydroxyvitamin D levels were significantly correlated with variables of inflammation, oxidative burden, and cell adhesion, independent of coronary artery disease, physical activity level, Charlson Comorbidity Index, variables of mineral metabolism, and New York Heart Association functional class.

Plasma 25-Hydroxyvitamin D Levels and Risk of Incident Hypertension
TLDR
Plasma 25(OH)D levels are inversely associated with risk of incident hypertension and also the association between predicted plasma 25( OH)D Levels and risk of incidents hypertension is studied. Expand
Serum 25-hydroxyvitamin D status of the US population: 1988-1994 compared with 2000-2004.
TLDR
Overall, mean serum 25(OH)D was lower in 2000-2004 than 1988-1994, and combined changes in BMI, milk intake, and sun protection appeared to contribute to a real decline in vitamin D status. Expand
25-hydroxyvitamin D and risk of myocardial infarction in men: a prospective study.
TLDR
Low levels of 25(OH)D are associated with higher risk of myocardial infarction in a graded manner, even after controlling for factors known to be associated with coronary artery disease. Expand
Serum 25-hydroxyvitamin D, ethnicity, and blood pressure in the Third National Health and Nutrition Examination Survey.
TLDR
Vitamin D status, which is amenable to intervention by safely increasing sun exposure or vitamin D supplementation, was associated inversely with BP in a large sample representative of the US population. Expand
Plasma levels of 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D and the risk of prostate cancer
TLDR
It is likely that the anti-carcinogenic effects of Vitamin D that have previously been described are related to the activity and expression of the Vitamin D receptor and should be investigated further. Expand
Vitamin D in preventive medicine: are we ignoring the evidence?
TLDR
Serum levels of 25(OH)D are the best indicator to assess vitamin D deficiency, insufficiency, hypovitaminosis, adequacy, and toxicity. Expand
Adiposity in relation to vitamin D status and parathyroid hormone levels: a population-based study in older men and women.
OBJECTIVE In small case-control studies, obesity was associated with worse vitamin D status. Our aim was to assess the association of adiposity (anthropometric measures as well as dual energy x-rayExpand
Serum 25-hydroxyvitamin D is unaffected by multiple freeze-thaw cycles.
TLDR
Determining whether vitamin D deficiency is present usually involves assessing the stores of vitamin D by measuring serum 25-hydroxyvitamin D (25OHD) concentrations, in combination with an assessment of parathyroid hormone concentrations. Expand
