Knowledge, attitudes and practices (KAP) of medical university students towards vitamin D deficiency in Saudi Arabia: a cross-sectional study.

The study reveals a gap in vitamin D knowledge among participants influenced by gender and study year. It suggests educational initiatives for male students to enhance their knowledge regarding vitamin D, while female students are encouraged to prioritise safe sun exposure, minimising the use of umbrellas and sunscreen. It also highlights the role of educational institutions as reliable sources of information and the influence of the COVID-19 pandemic on participants' attitudes and practices towards vitamin D.
