Low Vitamin D Levels in Stroke Survivors a Bad Sign, Study Finds

Posted 12 Feb 2015 by Drugs.com

THURSDAY, Feb. 12, 2015 – Low vitamin D levels are linked to an increased risk of suffering a severe stroke and poor health in stroke survivors, new research finds. The study included almost 100 stroke patients who were treated at a U.S. hospital between 2013 and 2014. All had experienced an ischemic stroke, which is a stroke caused by blocked blood flow to the brain. People with low blood levels of vitamin D – less than 30 nanograms per milliliter (ng/mL) – had about two times larger areas of stroke-related dead brain tissue than those with normal vitamin D levels, according to the study. The researchers also found that for each 10 ng/mL reduction in vitamin D level, the odds of a healthy recovery in the three months after stroke fell by about half, regardless of age or initial stroke severity. Although this study found an association between low vitamin D levels and poor stroke ... Read more

Low Vitamin D Levels in Childhood May Raise Heart Risks: Study

Posted 10 Feb 2015 by Drugs.com

TUESDAY, Feb. 10, 2015 – Adults who had low vitamin D levels as children and teens may be more likely to have hardening of the arteries, a new study suggests. Artery hardening is associated with heart disease. The study included more than 2,100 people in Finland. Their vitamin D levels were measured at ages 3 to 18, and they were checked for artery hardening at ages 30 to 45. Those with the lowest vitamin D levels when they were youngsters had a much higher risk for artery hardening as adults, according to the study published online Feb. 10 in the Journal of Clinical Endocrinology & Metabolism. This link was independent of other heart disease risk factors such as high blood pressure, smoking, poor eating, lack of exercise and obesity. Only an association was seen between childhood vitamin D levels and later heart health. The study did not prove a cause-and-effect relationship. Further ... Read more

Low Vitamin D Levels Linked to Risk of Preterm Birth in Study

Posted 8 Jan 2015 by Drugs.com

THURSDAY, Jan. 8, 2015 – Women who have low blood levels of vitamin D during pregnancy are more likely to give birth prematurely, a new study suggests. Women with the lowest levels of vitamin D were about 1.5 times as likely to deliver early compared to those with the highest levels, the investigators found. That finding held true even after the researchers accounted for other factors linked to preterm birth, such as overweight and obesity, and smoking. "Mothers who were deficient in vitamin D in early parts of pregnancy were more likely to deliver early, preterm, than women who did not have vitamin D deficiency," said Lisa Bodnar, associate professor of epidemiology and obstetrics and gynecology at the University of Pittsburgh, who led the study. Although this study found a strong association between vitamin D levels and preterm birth, Bodnar noted that the study wasn't designed to ... Read more

Low Levels of Vitamin D May Raise Early Death Risk: Study

Posted 19 Nov 2014 by Drugs.com

WEDNESDAY, Nov. 19, 2014 – Having low levels of vitamin D because of your genetics may raise the risk of early death, a new study suggests. But the risk is not linked with early death due to heart-related causes, the researchers added. The study, by Borge Nordestgaard of Herlev Hospital, Copenhagen University Hospital in Herlev, Denmark, and colleagues involved more than 95,000 white people of Danish descent in Copenhagen. The participants, who were from three different groups, had genetic variants known to affect levels of vitamin D. The researchers also considered other factors that could affect the participants' vitamin D levels, such as smoking, drinking alcohol, physical activity levels, blood pressure, cholesterol levels and body mass index (a measurement that helps determine if a person is a normal weight for their height). By the time the study ended in 2013, more than 10,000 ... Read more

Gene Study Finds No Proof Vitamin D Guards Against Type 2 Diabetes

Posted 1 Oct 2014 by Drugs.com

TUESDAY, Sept. 30, 2014 – There's no genetic evidence that high levels of vitamin D can prevent type 2 diabetes, a new study says. Some previous research had suggested that elevated levels of vitamin D might protect people against type 2 diabetes, raising the possibility of a link between vitamin D deficiency and the blood sugar disease. In this study, British researchers investigated the association between diabetes risk and vitamin D by focusing on genes that control blood levels of vitamin D. They found no connection between different variants of these genes and the risk of developing type 2 diabetes. The results were published Sept. 30 in The Lancet Diabetes & Endocrinology. "Our findings suggest that interventions to reduce the risk of type 2 diabetes by increasing concentrations of vitamin D are not currently justified. Observational studies that show a strong and consistent ... Read more

Women's Vitamin D Levels May Play Role in IVF Success

Posted 14 Aug 2014 by Drugs.com

THURSDAY, Aug. 14, 2014 – Vitamin D deficiency may lower a woman's chances of getting pregnant through in vitro fertilization (IVF), a small study suggests. Researchers in Italy compared the success of IVF in 154 women with vitamin D deficiency against that of 181 women with sufficient levels of vitamin D. Those with sufficient vitamin D levels were twice as likely to get pregnant as those with vitamin D deficiency, the team reported Aug. 14 in the Journal of Clinical Endocrinology & Metabolism Women with sufficient levels of vitamin D were also more likely to have better-quality embryos and had a greater likelihood of an embryo implanting in the uterus, the study found. According to the study authors, vitamin D levels of 20 to 30 nanograms per milliliter in their blood are considered sufficient or healthy, so the vitamin D-deficient women fell below that threshold. The study does not ... Read more

Low Vitamin D Levels May Boost Alzheimer's Risk, Study Finds

Posted 6 Aug 2014 by Drugs.com

WEDNESDAY, Aug. 6, 2014 – Older adults with too little vitamin D in their blood may have twice the risk of developing Alzheimer's disease as seniors with sufficient levels of the "sunshine vitamin," a new study finds. The research – based on more than 1,600 adults over age 65 – found the risk for Alzheimer's and other forms of dementia increased with the severity of vitamin D deficiency. But the findings aren't enough to recommend seniors take vitamin D supplements to prevent mental decline. "Clinical trials are now urgently needed in this area," said study researcher David Llewellyn, a senior research fellow in clinical epidemiology at the University of Exeter Medical School in England. Another expert agreed. "This shows you there is a link between vitamin D and the development of Alzheimer's," said Keith Fargo, director of scientific programs and outreach for the Alzheimer's ...

Low Vitamin D Levels Linked to High Blood Pressure

Posted 28 Jun 2014 by Drugs.com

THURSDAY, June 26, 2014 – Low levels of vitamin D may be a cause of high blood pressure, according to a new study. Previous research has suggested a strong link between low levels of vitamin D and high blood pressure, but a direct cause-and-effect relationship has not been shown. Vitamin D is nicknamed the sunshine vitamin because the body produces vitamin D when exposed to sunlight. People also get vitamin D through foods such as eggs, milk, yogurt, tuna, salmon, cereal and orange juice. In the new study, researchers analyzed genetic data from more than 146,500 people of European descent in Europe and North America. For each 10 percent increase in vitamin D levels, there was an 8 percent decrease in the risk of developing high blood pressure (or "hypertension"). The study was published online June 25 in The Lancet Diabetes & Endocrinology. "In view of the costs and side effects ... Read more

Vitamin D: A Key to a Longer Life?

Posted 17 Jun 2014 by Drugs.com

TUESDAY, June 17, 2014 – Higher levels of vitamin D may protect people from an earlier death, particularly from cancer and heart disease, suggests a new analysis of existing research. And, the opposite may also be true – low levels of vitamin D may be linked to a higher risk of premature death. But the researchers acknowledge that the review's findings aren't definitive. "People with low vitamin D die more frequently from heart disease and cancer, but it is not known if the low vitamin D is a cause of these diseases or just a byproduct of generally poor health," said study lead author Ben Schoettker, a post-doctoral scientist with the German Cancer Research Center in Heidelberg, Germany. Still, the research published online June 17 in BMJ does hint at the possibility that vitamin D may benefit people across genders, ages and Western countries, including the United States. The findings ... Read more

Jury Still Out on Benefits of Vitamin D

Posted 2 Apr 2014 by Drugs.com

TUESDAY, April 1, 2014 – Two new reports that analyzed research on vitamin D supplements found there's no reason to get excited yet about any possible health benefits. One review, from international researchers, found hardly any benefit. The other analysis suggested it may have what a specialist called a "huge" effect on lifespan, but the findings aren't definitive. "For now, the vitamin D story is intriguing," said Naveed Sattar, a professor of metabolic medicine at the University of Glasgow in Scotland, who co-wrote an editorial accompanying the studies. But more research is required before any definitive recommendations should be made, he said, since "there may yet be unexpected risks to supplementation." There's been intense debate about the value of vitamin D supplements in recent years, specifically over whether they contribute to better health. In one of the new reports, ... Read more

Vitamin D Deficiency May Be Linked to Heart Disease

Posted 27 Mar 2014 by Drugs.com

THURSDAY, March 27, 2014 – New research suggests people with lower levels of vitamin D are more likely to suffer from coronary artery disease and to have more severe forms of the illness. While the findings aren't definitive, they add to recent research that indicates vitamin D – the so-called sunshine vitamin – may play a role in preventing heart disease. The results "suggest vitamin D deficiency to be the cause rather than the consequence of atherosclerosis," said study investigator Dr. Monica Verdoia, a cardiologist at Eastern Piedmont University in Novara, Italy. Clogged arteries, or atherosclerosis, can lead to heart attack. While the study showed an association between vitamin D levels and heart disease risk, it did not prove a cause-and-effect link. The findings are scheduled for presentation Sunday at the American College of Cardiology's annual meeting in Washington, D.C. ... Read more

Low Vitamin D Could Up Risk for Birth Complication: Study

Posted 4 Feb 2014 by Drugs.com

TUESDAY, Feb. 4, 2014 – Vitamin D deficiency during the first 26 weeks of pregnancy may raise an expectant mother's risk of developing a severe form of high blood pressure called preeclampsia, a new study suggests. In what they termed one of the largest studies to date on the link, researchers analyzed vitamin D levels in blood samples from 700 pregnant women who later developed preeclampsia and 3,000 pregnant women who did not develop the potentially life-threatening condition. The overall risk of severe preeclampsia among the women in the study was 0.6 percent. Having sufficient levels of vitamin D was associated with a 40 percent reduced risk of severe preeclampsia. There was no association between vitamin D levels and mild preeclampsia, according to the study. While the study showed an association between vitamin D levels and preeclampsia risk, it did not prove a cause-and-effect ... Read more

Vitamin D Supplements Don't Help Your Health: Review

Posted 24 Jan 2014 by Drugs.com

FRIDAY, Jan. 24, 2014 – There's little evidence that vitamin D supplements offer substantial health benefits, and several ongoing studies are unlikely to change that, according to a large new review. Vitamin D supplements are taken by nearly half of American adults, according to the researchers. The review authors analyzed the findings of 40 studies and determined that taking vitamin D supplements does not reduce the risk of heart attack, stroke, cancer or bone fractures in the general population by more than 15 percent. That result suggests that vitamin D supplements likely provide few, if any, health benefits, said Dr. Mark Bolland, of the University of Auckland in New Zealand, and colleagues. The study appears in the Jan. 25 issue of The Lancet Diabetes & Endocrinology. Unless used in people with vitamin D deficiency, there is legitimate concern that taking vitamin D supplements ...

Vitamin D Deficiency Might Be Overdiagnosed in Blacks, Study Suggests

Posted 21 Nov 2013 by Drugs.com

WEDNESDAY, Nov. 20, 2013 – Black adults typically have low levels of vitamin D in their blood, but they are on par with whites when it comes to the "active" form of vitamin D used by the body's cells, a new study finds. Experts said the findings go a long way toward explaining a paradox: Blacks usually have fairly low vitamin D levels, but have greater bone mass than whites. Vitamin D is needed to maintain strong bones. What's more, the results suggest that doctors may be overdiagnosing vitamin D deficiency in black patients, said lead researcher Dr. Ravi Thadhani, chief of nephrology at Massachusetts General Hospital, in Boston. "We're suggesting that the definition of vitamin D deficiency needs to be rethought," said Thadhani, whose report appears in the Nov. 21 issue of the New England Journal of Medicine. Right now, doctors use a blood test that measures a person's total ... Read more

Low Vitamin D Tied to Anemia Risk in Kids

Posted 23 Oct 2013 by Drugs.com

TUESDAY, Oct. 22 – Children with low levels of vitamin D may be at increased risk for anemia, according to a large new study. Researchers analyzed blood samples from more than 10,400 children and found that vitamin D levels were consistently lower in youngsters with anemia, a condition involving lower-than-normal levels of red blood cells. Kids with vitamin D levels below 30 nanograms per milliliter (ng/ml) were nearly twice as likely to have anemia as those with normal vitamin D levels. Children with vitamin D levels below 30 ng/ml have mild vitamin D deficiency while those with levels at or below 20 ng/ml have severe deficiency, according to the study. Both require treatment with vitamin D supplements. The researchers also found that 14 percent of black children had anemia, much higher than the 2 percent rate among white children. Black children also had lower vitamin D levels ... Read more
