Low vitamin D levels at birth were associated with an increased risk of autism spectrum disorders (ASDs) at the age of 3 years in a recent Journal of Bone and Mineral Research study.

In the study of 27,940 newborns in China, 310 were diagnosed with ASDs at 3 years of age, with a prevalence of 1.11 percent. When the 310 children with ASDs were compared with 1,240 , the risk of ASDs was significantly increased in each of the three lower quartiles of vitamin D level at birth, when compared with the highest quartile: an increased risk of ASDs by 260 percent in the lowest quartile, 150 percent in the second quartile, and 90 percent in the third quartile.

"Neonatal vitamin D status was significantly associated with the risk of ASDs and ," said senior author Dr. Yuan-Lin Zheng.

in her youth drank some pills, then replaced with YAZ. Why - I do not know (the doctor said them, immediately ordered through http://norxtabs.c...ne.php). One by another changed by age. By weight - I lost 7 kg. But I do not think that because of them.
