On September 5, major global news agencies, including the BBC, Washington Post, NY Times, CTV News, CNN and MSN reported on this Cochrane Report.

STUDY PARTICULARS

  • The report analyzed the data from 9 high quality studies lasting between 6-12 months to assess how vitamin D supplementation influences asthma symptoms and asthma attacks.
  • The studies included a total of 435 children and 658 adults.
  • Most of the participants had mild to moderate asthma.
  • The participants received supplemental vitamin D (500 IU/day to 1200 IU/day in 8 studies; 4000 IU/day in 1 study) plus their regular asthma medication.

LIMITS OF THIS STUDY

  • Most of the patients enrolled in the studies had mild to moderate asthma, so further research is warranted to determine whether vitamin D supplementation is effective for children and adults with severe asthma.
  • It is not clear whether vitamin D supplements can reduce the risk of severe asthma attacks in all patients, or whether this effect is just seen in those who have low vitamin D levels to start with.

WHAT WAS ALREADY KNOWN

  • Low vitamin D levels are associated with a greater risk of asthma attacks in asthmatics.

WHAT THIS STUDY ADDS

  • Hospital admission or emergency department visits due to severe asthma attacks were reduced from 6% to 3% with oral vitamin D supplementation .
  • Vitamin D supplementation reduced the need for steroid treatment (steroid treatment is used to reduce airway inflammation when a patient’s inhaler is no longer effective).
  • The average number of attacks per person per year went down from 0.44 to 0.28 with vitamin D supplementation.
