1) Only 5% of females and 2.5% of males, ever had a vitamin D test
2) Only 5% took a vitamin D (only) supplement
3) None appeared to be aware of the Cancer Association
- Dermatologists use sun block, stay indoors, and have low vitamin D (Thai in this study) – Dec 2018
- Medical students in Pakistan – 1 in 3 aware than sun creates Vitamin D, 1 in 12 get noon sun – Jan 2015
- Fewer than 1 in 4 of nutrition students actually consumed RDA of Vitamin D – May 2013
- Med training still less than 25 hours in nutrition - much less vitamin D - Sept 2010 Doctors get just 25 hours of nutrition training, vs 4 years
- Avoiding the sun (and vitamin D) – most Chinese medical students do not want darker skins – Feb 2015
- 1 in 4 medical schools have a nutrition course and nutrition counseling is rarely reimbursed, – JAMA Sept 2017
- 17 reasons why are doctors reluctant to accept vitamin D - Reasons include: few nutrion classes, taught that > 2,000 IU can be toxic (wrong - Toxic is >2,000 IU /kilogram)

Vitamin D deficiency is a worldwide public health problem. The objective of this survey was to assess the undergraduate students' vitamin D status and knowledge about this vitamin.
Materials and methods: an online multi-choice survey was designed and launched in Northern Poland (Gdansk region). The first part of the survey assessed diet, supplementation, UV radiation exposure (UVE) and general health of respondents. The second part was a vitamin D knowledge test (vitamin D optimal level, deficiency-related diseases). 1766 student volunteers responded to the survey: 369 male and 1397 female. Data was divided according to the respondents' sex and university affiliation. Appropriate parametric or non-parametric statistical tests were used with statistical significance set at p<0.05.
Results: regular consumption of vitamin D-rich food was high, except for fish (only 18; 22%). High number of participants did not declare any type of supplementation (43; 44%) and only occasionally were exposed to UV (77%; 80%). The most frequently recognized disease linked to vitamin D was osteoporosis. Medical University students obtained higher test scores (4,55), however this did not correlate with healthy vitamin D habits.
Conclusion: undergraduate medical and non-medical students have unsatisfactory vitamin D status and poor understanding of its function and impact on health, which implies the need for changes in the educational program.
