Aim:? The relationship between depression in adolescents and vitamin D was studied in a case-series which included effects of vitamin D supplementation.
Methods:? Serum 25OH vitamin D (25OHD) levels in 54 Swedish depressed adolescents were investigated.
Subjects with vitamin D deficiency were given vitamin D3 over three months (n=48).
To evaluate well-being and symptoms related to depression and vitamin D status the WHO-5 well-being scale,
The Mood and Feelings Questionnaire (MFQ-S), and a vitamin D deficiency scale were used.
Results:? Mean serum 25OHD in the depressed adolescents was 41 at baseline and 91 nmol/L (p<0.001) after supplementation.
Basal 25OHD levels correlated positively to well-being (p<0.05).
After vitamin D supplementation
- well-being increased (p<0.001)
and there was a significant improvement in seven of the nine items in the vitamin D deficiency scale; in
- depressed feeling (p<0.001),
- irritability (p<0.05), (p<0.001),
- tiredness (p<0.001),
- mood swings (p<0.01),
- sleep difficulties (p<0.01),
- weakness (p<0.05),
- ability to concentrate (p<0.05) and
- pain (p<0.05).
There was a significant amelioration of depression according to the MFQ-S (p<0.05)
Conclusion:? This study showed low levels of vitamin D in 54 depressed adolescents, positive correlation between vitamin D and well-being,
and improved symptoms related to depression and vitamin D deficiency after vitamin D supplementation.
