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.

Objectives: To assess the effect of multidisciplinary community health services on reducing blood lead in children. Material and methods: Retrospective observational study, before-after type. The information of an intervention program in the "Mi Peru" district was analyzed. The population consisted of 1,191 children of both genders who had results of blood lead level and who were evaluated during 2016 and 2017. The sample consisted of 187 children with blood lead levels ≥10 μg/dL. Community health services had three components: comprehensive multidisciplinary care, health education and house calls. Results: The blood lead level at the start of the intervention, 88.5% (n=139) belonged to category II and 11.5% (n=18) belonged to category III. At the end of the intervention, 66.9% (n=105) resulted in category I, the proportion of lead levels belonging to categories II and III was reduced to 29.9% (n=47) and 3.2% (n=5) respectively. In relation to the blood lead level at the beginning of the intervention and at the end of the intervention, the initial mean of 13.96 μg/dL was reduced to 8.96 μg/dL and the median from 12.40 μg/dL to 8.20 μg/dL (p<0.001). Conclusions: Community health services reduced blood lead levels in children with elevated blood lead levels. It is suggested to promote and strengthen the comprehensive house calls and health education about the risks of lead exposure.
