Low vitamin D strikes again

  April 27, 2013

According to a study published in the March issue of the journal Pediatrics, low levels of vitamin D was "significantly associated with offspring language impairment." Serum levels of 25(OH)-vitamin D were measured in 743 Caucasian women at 18 weeks and grouped into four categories.  The children were then measured at 2, 5, 8, 10, 14, and 17 years old with the Child Behavior Checklist and the Peabody Picture Vocabulary Test.  There were no differences noted in behavioral/emotional  problems between groups and age categories.  However, those mothers with insufficient vitamin D levels (less than or equal to 46 nmol/L) had an almost two-fold increase in language impairment in their offspring compared to those mothers with sufficient vitamin D levels (greater than 70 nmol/L).   The authors conclude," Maternal vitamin D supplementation during pregnancy may reduce the risk of developmental language difficulties among their children."
