Tuesday Jan 17, 2012 (foodconsumer.org) -- A new study in the December 2012 issue of Diabetes suggests that taking vitamin D supplements or frequent exposure to the sun during pregnancy may reduce risk of type 1 diabetes in the offspring.
The study shows that women whose serum vitamin D levels were in the lowest quartile were more than twice as likely as those whose levels were in the highest quartile to have children with type 1 diabetes.
Ingvild M. Sørensen of Oslo University Hospital Ullevål in Oslo, Norway and colleagues compared 109 women delivering a child who developed type 1 diabetes before 15 years of age with 219 control women who had no diabetic children for their levels of serum vitamin D. All participants were part of a cohort of 29,072 women in Norway.
The study findings suggest that a randomized intervention trial should be initiated to examine whether enhacing maternal 25-OHD or vitamin D status during pregancy may help cut the risk of type 1 diabetes in children.
Type 1 diabetes or Juvenile onset diabetes is often found in children. Children with this disease can't produce sufficient amounts of insulin to handle blood sugar.
Symptoms of type 1 diabetes include being very thirsty, feeling hungry, feeling tired or fatigued, having blurry eyesignt, lossing the feeling or feeling tingling in feet, losing weight without known causes and urinating more often.
