TLDR Many people in Misurata City have low vitamin D, especially women and those aged 35-45, with levels dropping in winter and spring.
This study of 1,002 individuals in Misurata City from 2019 to 2023 found a widespread vitamin D deficiency, especially among females (80.42%) compared to males (19.57%). The most affected age group was 35-45 years, with a deficiency rate of 34.1%. Seasonal variations showed lower vitamin D levels in winter and spring, likely due to reduced sunlight exposure, while levels increased in autumn and summer. The study highlights the importance of monitoring vitamin D to prevent health issues like hair loss and chronic diseases, although no correlation was found between blood calcium concentration and low vitamin D levels.
