Vitamin A and Zinc Profile of Plasmodium falciparum Malaria in Selected Communities in Delta Central Senatorial District, Delta State, Nigeria
Main Article Content
Abstract
Malaria remains a major public health concern in sub-Saharan Africa, where micronutrient deficiencies may complicate infection. This study assessed malaria parasitemia intensity and serum vitamin A and zinc concentrations in Delta Central Senatorial District, Delta State, Nigeria. Thick blood film microscopy was used to examine 566 participants for malaria parasitemia. Serum vitamin A and zinc concentrations were measured in a subset of 50 parasitemic volunteers using the Carr–Price colorimetric method and flame atomic absorption spectrophotometry, respectively. Analysis of variance was used to compare micronutrient concentrations between parasitemic participants and uninfected controls. Moderate parasitemia (1,000–9,999 parasites/µL) predominated (75.8%), followed by mild parasitemia (24.2%). No parasite densities of ≥10,000 parasites/µL were observed. Serum vitamin A and zinc concentrations were numerically higher in parasitemic participants than in uninfected controls, but neither difference was statistically significant (p > .05). The findings document a predominance of moderate parasitemia without statistically significant differences in the measured micronutrient concentrations between infected participants and controls. This study provides local evidence to inform malaria control strategies that consider both infection and nutritional status in endemic populations.
