Study of Vitamin D Deficiency in Adolescent Females (10-18 years old) In Cairo

Abstract Background Vitamin D deficiency is a common problem among Egyptian females across all age groups, for whom contributing factors include inadequate sun exposure possibly related to cultural/social factors, and insufficient dietary calcium, wearing a sunscreen reduces vitamin D synthesis in the skin by more than 95%. Not only environmental factors, such as sun exposure and nutrition, but also genetic and possibly also epigenetic factors are determinants of serum 25(OH) D. Aim We sought to determine the frequency of occurrence of vit D deficiency in Egyptian adolescent females aged 10-18 years in Cairo. Methods Study was conducted on 90 healthy adult females aged (10-18) years and classified them into: Sufficient group: with vitamin D level >30ng/ml, (40%) of participants. Mild deficient group: with vitamin D level between 21-29ng/ml (14.44%) of participants. Moderate deficient group: with vitamin D level between 10-20ng/ml (11.11%) of participants. Severe deficient group: with vitamin D level
