The Prevalence of Vitamin D Deficiency: A Comparison Study in Two Libyan Cities Exemplified by Tarhuna and Tripoli
Vitamin D is a fat soluble vitamin, mostly made from 7 hydroxycholesterol in the skin with the aid of ultraviolet B radiation (UVB). Its function is facilitating the calcium and phosphorus absorption from the intestines that enables them to be transported among others to bones and teeth. In addition, maintaining the blood calcium homeostasis. Its deficiency leads to rickets and osteoporosis. This study aimed to analysis of the vitamin D levels in a randomized samples in the two Libyan cities (Tarhuna & Tripoli) to contribute in the evaluation of the prevalence of vitamin D deficiency in the society. Therefore, vitamin D levels among 106 cases (52 from Tarhuna and 54 from Tripoli) were examined and measured. Results of current study showed that 50 out of 106 cases (47.17%) were deficient in vitamin D, while insufficient vitamin D levels were found in 25 out of 106 cases (23.58%).
