Insights
Young children with iron deficiency anemia show lower vitamin D levels. Severe iron deficiency is linked to a higher prevalence of vitamin D deficiency in Iraqi children.
Area of Science:
- Pediatric Nutrition
- Nutritional Biochemistry
- Public Health
Background:
- Iron deficiency and vitamin D deficiency are prevalent global health issues in children.
- Understanding the interplay between these micronutrient deficiencies is crucial for effective interventions.
Purpose of the Study:
- To evaluate vitamin D status in young Iraqi children with iron deficiency.
- To investigate the association between iron status and vitamin D levels in this population.
Main Methods:
- Cross-sectional study involving 95 infants/toddlers with iron deficiency (ID/IDA) and 95 healthy controls (6-24 months).
- Data collected via questionnaire; iron status assessed by hemoglobin and ferritin.
- Vitamin D status determined by serum 25-hydroxyvitamin D [25(OH)D] levels, categorizing into insufficiency, deficiency, and sufficiency.
Main Results:
- Children with iron deficiency anemia (IDA) had significantly lower 25(OH)D levels compared to iron deficiency (ID) and control groups.
- Vitamin D insufficiency and deficiency were more prevalent in IDA (70% deficiency) and ID (60% deficiency) groups than controls.
- A significant positive correlation was observed between serum ferritin and 25(OH)D levels.
Conclusions:
- Young children with severe iron deficiency, particularly IDA, exhibit a higher prevalence of vitamin D deficiency.
- The positive correlation suggests a potential link between iron stores and vitamin D status in young children.
- Findings highlight the importance of assessing both iron and vitamin D status concurrently in pediatric populations.
Abstract:
This study aimed to assess vitamin D status and its association with iron status in young Iraqi children. A total of 95 infants and toddlers with iron deficiency (ages ranging from 6 to 24 months) and an equal number of 95 healthy subjects with normal hemoglobin (Hb) and sufficient ferritin level with matching age were included as a control group. A specially designed questionnaire was used to collect data. The cases were classified into iron deficiency (ID) and iron deficiency anemia (IDA) according to hemoglobin and ferritin levels. The cases and control groups were subdivided into vitamin insufficiency (VDI), vitamin D deficiency (VDD), and vitamin D sufficiency groups according to 25-hydroxyvitamin D [25(OH)D] levels. Young children with IDA have significantly lower serum levels of 25(OH) D compared with ID and control groups (p<0.05). According to iron status, VDI and VDD were present in 20% and 70% of IDA, 25.7% and 60%of ID, and 26.3% and 30.5% of control groups, respectively, with a significant difference in vitamin D level (p<0.05) among studied groups. A significant positive correlation (p=0.000) was found between serum ferritin level and 25(OH) D level in studied patients. Young children with severe iron deficiency have a higher prevalence of vitamin D deficiency, and there was a significant positive correlation between serum ferritin level and 25(OH) D levels among studied children.

Role of Skin in Vitamin D Synthesis
