Abstract

Aim:

Malnutrition, anemia, and lead exposure are important public health problems.

Introduction:

To assess nutritional status, anemia, and eating habits and their relationship to elevated blood lead levels in children.

Materials and Methods:

Descriptive study conducted with data from children evaluated in a district of Callao, Peru. The variables studied were: nutritional status, based on anthropometric measurements; anemia, determined by blood hemoglobin concentration; dietary habits, evaluated by the 24-hour dietary recall method and food consumption frequency; and blood lead, determined by LeadCare II analyzer.

Results and Discussion:

A total of 425 children participated, with a median age of 6 years (IQR=5; Q3=9, Q1=4), 52.2% (n=222) were female and 71.3% (n=303) had blood lead level (BLL) ≥5μg/dL. Among children with BLL ≥5 μg/dL, 11.6% (n=35) presented poor nutritional status, 9.9% (n=30) had anemia, and 63% (n=191) had inadequate eating habits. Of the children with inadequate eating habits, 17.4% (n=47) had poor nutritional status and 15.9% (n=43) had anemia, compared to children with adequate eating habits (p<0.001). In children with BLL ≥5 μg/dL, the children's median hemoglobin, body weight, and height were 12.2 g/dL, 21.6 Kg, and 114.8 cm, respectively; while in those with Pb levels <5 μg/dL it was 12.5 g/dL, 29 Kg and 126.55 cm, respectively (p<0.05).

Conclusion:

Nutritional status, anemia, and eating habits did not differ according to BLL; however, lower median hemoglobin, weight, and height were found in children with elevated lead levels. Children with subnormal nutritional status and children with anemia presented a shorter time to reach elevated blood lead levels.
