There is a significant association between hypocalcemia and vitamin D deficiency with migraine attacks and induced loss of function among patients with migraine, a new study found. Researchers conducted a population-based, retrospective, cross-sectional analysis of the Nationwide Inpatient Sample (NIS) in migraine hospitalizations. They found:
- Between 2003 - 2014, of the total 446,446 migraine hospitalizations, 1,226 (0.27%) and 2,582 (0.58%) presented with hypocalcemia and vitamin D deficiency, respectively.
- In multivariable analysis, hypocalcemia and vitamin D deficiency were associated with elevated odds of extreme loss of function.
- There was a higher prevalence and higher odds of migraine among vitamin D deficiency patients vs patients with hypocalcemia and no deficiency, respectively.
