A new study has found that vitamin D deficiency may increase the risk of chronic headache.
In the study, from the University of Eastern Finland, scientists analysed data relating to approximately 2,600 men aged between 42 and 60 years who had participated in the Kuopio Ischaemic Heart Disease Risk Factor Study.
A total of 250 men (9.6 per cent) reported frequent headache. The average serum 25-hydroxyvitamin (OH)D concentration among those with frequent headache was 38.3 nmol/L compared with 43.9 nmol/L among those without frequent headache. After multivariable adjustments, those in the lowest vs. the highest serum 25(OH)D quartile had 113 per cent higher odds for frequent headache.
