In search of risk factors for attention-deficit hyperactivity disorder (ADHD) have been found by Finnish researchers that the disease occurred to a third more when the mothers had during pregnancy is a low Vitamin D level.
The ADHD risk in children whose mother was in the first and/or second trimester of pregnancy, a Vitamin D deficiency, 34 percent higher than in children of mothers with sufficient Vitamin D supply. The study is the first of its kind that proves such a connection. Professor Sourander, University of Turku, said: "This study provides strong evidence that a low Vitamin D level depends on during pregnancy with ADHD in the offspring together. Since ADHD is one of the most common chronic diseases in children, the research results are of great importance for public health."
Vitamin-D deficiency is in many Lächange a Problem
Sourander noted that Vitamin-D deficiency is a global Problem. In Finland, a national recommendation for taking a daily 10 micrograms of Vitamin D during pregnancy. Nevertheless, the Vitamin D intake, in some cases, for example, some immigrant mothers is not sufficient.
The study included 1.067 between 1998 and 1999-born children for whom ADHD was diagnosed. They were compared with the same number of children without ADHD. For this, the researchers used an unusually large collection of about two million serum samples from the first pregnancy half of mothers-to-be. Then there was the recommendation for Vitamin D supplementation during pregnancy still.
