Insights
Vitamin D deficiency is prevalent in children in Jeddah, Saudi Arabia, with over 86% affected. This highlights the need for vitamin D supplementation strategies to combat this deficiency.
Area of Science:
- Pediatrics
- Endocrinology
- Public Health
Background:
- Vitamin D deficiency is a global health concern.
- It is often an unrecognized epidemic affecting various populations worldwide.
Purpose of the Study:
- To assess vitamin D status in children residing in Jeddah, Saudi Arabia.
- To investigate the relationship between vitamin D levels and other relevant variables in this pediatric population.
Main Methods:
- A cross-sectional study involving 510 healthy children aged 4-15 years in Jeddah.
- Measurements included serum calcium, phosphorus, alkaline phosphatase, and 25-hydroxyvitamin D [25(OH)D].
- Dietary vitamin D intake and sunlight exposure duration were assessed; deficiency defined as 25(OH)D <20 ng/mL (relative) or <7 ng/mL (severe).
Main Results:
- The mean 25(OH)D level was 13.07 ± 7.81 ng/mL.
- A high prevalence of deficiency was found: 58.82% had relative deficiency and 27.45% had severe deficiency.
- Vitamin D deficiency was more common in females and in Saudi and Yemeni children compared to Egyptians; inverse correlation with bony aches and sunlight exposure was observed.
Conclusions:
- This study reveals a high prevalence of vitamin D deficiency among children in Jeddah.
- Food product fortification with vitamin D is recommended as a preventive measure for this population.
Objective:
Vitamin D deficiency is an unrecognized epidemic and a common health problem worldwide. This study was conducted to evaluate the vitamin D status in children living in Jeddah, Saudi Arabia and to study its relation to various variables.
Materials And Methods:
A cross-sectional study was conducted in the pediatric clinic in Jeddah Clinic Hospital-Kandarah, Jeddah, KSA, from October through December 2010, in which 510 healthy children aged 4-15 years were enrolled. Serum calcium, phosphorus, alkaline phosphatase and 25-hydroxyvitamin D [25(OH)D] were measured. Dietary vitamin D intake and duration of daily sunlight exposure were determined. 25(OH)D levels <20 ng/mL and <7 ng/mL were defined as relative and severe vitamin D deficiency, respectively.
Results:
The mean concentration of 25(OH)D was 13.07 ± 7.81 ng/mL. Seventy subjects (13.72%) had normal 25(OH)D level ranging 20-70 ng/mL. Three hundred (58.82%) had relative 25(OH)D deficiency and 140 (27.45%) had severe deficiency (P=0.000). 220 (43.14%) subjects were males and 290 (56.86%) were females having a statistically significant higher incidence of 25(OH)D deficiency (P=0.019). 54.9% were Saudis, 27.45% were Yemenis and 11.76% were Egyptians. Saudis and Yemenis were more subjected to 25(OH)D deficiency in comparison to Egyptians and other nationalities (P=0.01). There were significant inverse correlations between 25(OH)D levels and bony aches (P=0.000). 56.25% of asymptomatic children had vitamin D deficiency (P=0.000). Duration of sunlight exposure and daily intake of vitamin D had significant effects on serum level of vitamin D (P=0.000).
Conclusions:
A high prevalence of vitamin D deficiency in children living in Jeddah was observed in this study. Vitamin D supplementation of food products can prevent vitamin D deficiency in these children.

Role of Skin in Vitamin D Synthesis
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).
