Asthma Clinical Trial
Official title:
DO IT Trial: Vitamin D Outcomes and Interventions In Toddlers
Vitamin D can be made in the skin by exposure to sunlight and can be found in certain foods.
Vitamin D levels are alarmingly low in many North American children. Several health issues
have been linked with low vitamin D. These include colds caused by viruses and asthma
attacks. However, no study has determined whether vitamin D supplementation can reduce the
risk of these conditions in young children where they are most common and most severe.
The goals of this study are to determine whether wintertime high dose vitamin D
supplementation of preschoolers can prevent colds and asthma attacks. The investigators also
aim to work out how much money would be saved by the health care system and society if
preschoolers were routinely supplemented with Vitamin D during the winter. The investigators
believe that preschoolers receiving 'high dose' vitamin D supplementation during the
wintertime will be less likely to have colds, asthma attacks, and low vitamin D levels and
will be less likely to use the medical system and keep their parents away from work.
