Micronutrient Biomarkers and Their Association with Malaria Infection in Children in Buea Health District, Cameroon

Recently malaria and micronutrient deficiencies have become a major worldwide public health problem, particularly in Africa and other endemic countries with children under 5 years old being the most vulnerable. Apart from nutritional problems that cause micronutrient deficiencies, studies have also reported that parasitic infections like malaria can affect the levels of micronutrients. Thus, this research was aimed at assessing the serum levels of micronutrient biomarkers and their association with malaria infection in children under 5 years old in the Buea Health District. Method: This cross-sectional study recruited 80 participants from February to April 2024. The micronutrient biomarkers levels were measured using a Q-7plex Human Micronutrient Measurement Kit. Results: There were changes in serum micronutrient biomarkers levels between malaria infected and healthy children. Ferritin was higher in sick children (23.53 μg/L ± 7.75) than in healthy children (19.07 μg/L ± 3.87), significantly (p < 0.002). The same trend was observed with the soluble transferrin receptor being higher (p < 0.049) in sick children (3.74 mg/L ± 1.92) compared to healthy ones (3.08 mg/L ± 0.64). In addition, the levels of retinol-binding protein 4 and thyroglobulin levels were not significantly different between the sick and healthy children. Therefore, this study revealed that malaria causes alterations in the serum levels of micronutrient biomarkers and consequently affects micronutrient levels in children below the age of 5 in the Buea Health District.
