Knowledge attitude and practices of university students to Vitamin D and Vitamin D supplements during times of low sun exposure and post lockdown.

Abstract

Vitamin D deficiency is prevalent in Saudi Arabia. Inability to get sun exposure greatly influences Vitamin D levels. Getting enough Vitamin D during childhood and young adulthood can prevent possible future diseases. We aim to estimate the level of knowledge of Saudi University students about Vitamin D and Vitamin D supplements, to correlate it with their attitudes and practices to sun exposure and Vitamin D supplements and to compare between males and females. This is an epidemiological cross-sectional KAP study conducted at King Saud University in Riyadh. A stratified random sampling technique was used where students were randomly selected from 3 colleges and stratified to males and females. N= 767 students completed the online survey used to assess the knowledge, attitudes, and practices of the students. We found that the level of knowledge of university students was moderate to low (mean equivalent to 40%) whereas females had better knowledge. Also, their practices are not sufficient to maintain healthy Vitamin D levels as only 8.2% stay in the sun for more than an hour during weekdays. Only 10.2% of students take regular Vitamin D supplements, where females are the more likely users. 99.1% of students stay indoors during work. The knowledge about Vitamin D is low among university students but slightly higher in females and medical students. Almost all participants work indoors and most of them wear a mask whenever going out. Few students take regular Vitamin D supplements. Females agreed more they have Vitamin D deficiency and take supplements more than males.
