How many people know about vitamin D?
July 7, 2012 -- Brant Cebulla
Ever wonder how many people know as much about vitamin D as you? Last summer, Professor Sandra Clips and colleagues from John Hopkins University wanted to know this, too, and published some interesting results.
Clipp, SL et al. Sun-seeking behavior to increase cutaneous vitamin D synthesis: When prevention messages conflict. Public Health Reports, 2011.
In 2007, they sent out a questionnaire to a group of people who lived in Washington County, Maryland (a semi-rural county) in 1989 and have been followed ever since. From this questionnaire the researchers sent out, they got a total of 8,027 valid responses.
Here is what they found:
- 30% were aware that unprotected sun exposure increased vitamin D levels.
- Women were a little more aware of this interaction than men (32% vs. 28%).
- Education was a significant factor. Awareness increased from 23% to 25% to 38% among those who had <12, 12 and >12 years of education, respectively.
- 42% of people who took vitamin D supplements were aware of the vitamin D-sun exposure interaction compared to just 25% of non-supplement users.
