Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent mental health disorders. In recent years, the impacts of various micronutrients on ADHD have been studied. However, vitamin D has received much less attention. This study was aimed at evaluating the association and level of serum vitamin D in children with ADHD.
MATERIALS & METHODS: This case-control study was carried out, in 2012, on 6 to 12 yr-old children. Thirty-seven were children with ADHD in the cases group and another 37 healthy children were in the control group. Venous blood sample was drawn from each child to measure the serum level of vitamin D. Other variables were compared as well.
The mean serum vitamin D level of children with ADHD (19.11±10.10 ng/ml) was significantly lower than that of the control group (28.67±13.76 ng/ml) (P<0.001).
Deficiency of vitamin D has been proved in various psychiatric diseases. This study evidenced a significantly low level of serum vitamin D in children with ADHD. This suggests the need for regularly monitoring of serum vitamin D levels and treatment of patients with vitamin D deficiencies.
注意缺陷多动障碍（ADHD）是最常见的心理健康障碍之一。近年来，已对各种微量营养素对ADHD的影响进行了研究。然而，维生素D受到的关注要少得多。本研究旨在评估ADHD患儿血清维生素D的关联及水平。
本病例对照研究于2012年对6至12岁儿童进行。病例组有37名ADHD患儿，对照组有另外37名健康儿童。从每个儿童采集静脉血样以测量血清维生素D水平。还对其他变量进行了比较。
ADHD患儿的血清维生素D平均水平（19.11±10.10 ng/ml）显著低于对照组（28.67±13.76 ng/ml）（P<0.001）。
已证实维生素D缺乏存在于各种精神疾病中。本研究证明ADHD患儿血清维生素D水平显著较低。这表明需要定期监测血清维生素D水平并对维生素D缺乏患者进行治疗。
