Anemia in urban underprivileged children. Iron, folate, and vitamin B12 nutrition
Insights
Iron deficiency anemia is common in young children in poor urban areas, decreasing with age. New methods are needed to identify at-risk families for childhood nutritional anemia.
Area of Science:
- Pediatric Nutrition
- Hematology
- Public Health
Background:
- Nutritional anemia is a significant global health concern in children.
- Poor urban environments often present unique challenges to child nutrition.
- Understanding the specific types and prevalence of anemia is crucial for targeted interventions.
Purpose of the Study:
- To investigate the prevalence and types of nutritional anemia in children.
- To identify age-specific patterns of anemia and iron deficiency.
- To explore potential familial risk factors for nutritional anemia.
Main Methods:
- A cross-sectional study was conducted on 344 children aged 1-16 years.
- Data collection included assessment of anemia and biochemical markers for iron deficiency.
- Folate and vitamin B12 levels were evaluated to rule out other nutritional deficiencies.
Main Results:
- Iron deficiency anemia was prevalent in 1-year-olds (23%), with 53% showing biochemical iron deficiency.
- Anemia rates were low in older children, and iron deficiency prevalence decreased with age.
- Folate deficiency and vitamin B12 deficiency were not significant contributors to anemia in this cohort.
Conclusions:
- Iron deficiency is the primary cause of nutritional anemia in young children in this urban setting.
- Age is a significant factor in the prevalence of nutritional anemia and iron deficiency.
- Current familial variables do not effectively identify children at risk; novel approaches are required.
Abstract:
The prevalence and type of nutritional anemia was investigated in 344 children aged 1 to 16 years of mixed race and living in a poor urban setting. Iron deficiency anemia was common in 1-year-old children (23%) as was biochemical evidence of iron deficiency (53%). Anemia rates were minimal in older children and the prevalence of iron deficiency decreased with age. Folate deficiency did not appear to contribute to the etiology of anemia, and nutritional vitamin B12 deficiency was not present. No-relationship could be found between a number of familial variables and hematological nutritional status. It is suggested that to identify families whose children are at risk for nutritional anemia new approaches will be needed to define their characteristics.
