Sun exposure, dressing habits, and vitamin D status in Morocco
Sunlight is the main source of vitamin D. Almost 80% of vitamin D3 is produced in the skin. The region of Draa Tafilalet benefits from long daily sunshine time.

| Sumario: | Sunlight is the main source of vitamin D. Almost 80% of vitamin D3 is produced in the skin. The region of Draa Tafilalet benefits from long daily sunshine time. As such, vitamin D deficiency should be low in this region. However, dressing habits can highly influence vitamin D status. This study aimed to evaluate sun exposure and its relation to vitamin D status among the general population in the region of Draa-Tafilalet, Morocco. Clinical, biological, and sociodemographic data were obtained from 331 adults visiting local healthcare units during the summers of 2019 and 2020. Plasma 25(OH)D2/D3 was measured by immunofluorescence. The prevalence of vitamin D deficiency was 37.5%, while Vitamin D insufficiency represented 56.5%. Most of the studied population (76.4%) had restricting dressing habits and exposed only their faces. statistic tests showed a correlation of vitamin D levels with daily sun exposure (r= 0.308, p<0.001), dressing habits (p<0.001), age (r= -0.141, p=0.01), sex (p<0.001), physical activity level (p=0.003), and BMI (r= -0.298, p<0.001). The study showed a high prevalence of vitamin D deficiency in this region. Similarly, it exposed the effects of restricting clothes and low daily sun exposure on vitamin D status. |
