摘要 Background:Anaemia and malaria are common and life-threatening diseases among preschool-aged children in many tropical and subtropical areas,and Malawi is no exception.Accordingly,this study aimed to examine the association of referral clinical malaria with anemia(hemoglobin[Hb]<110g/L)in preschool-aged children in Malawi.Methods:Using cross-sectional data obtained from the 2015-2016 Malawi Micronutrient Survey(MNS),multivariate logistic regression models were construaed using surveylogistic to account for the complex survey design.Blood samples of 1051 children aged 6-59 months were evaluated for malaria(using rapid diagnostic test[RDT]-SD BIOLINE Malaria Ag P.f/Pan test histidine-rich protein(HRP-Ⅱ)^™),Hb(using HemoCue 301),a-1-acid glycoprotein(AGP),and serum ferritin biomarkers(using simple sandwich enzyme-linked immunosorbent assay technique,ELISA)and inherited blood disorders from dry blood samples(DBS)using polymerize chain reaaion(PCR).Diagnosis of clinical malaria was made on the basis of fever and a positive rapid diagnostic test(RDT).Results:Of the 1051 PSC analysed,29%had anaemia while 24.4%had a referral to the hospital due to malaria.After adjustments for known confounders,PSC with a history of referral clinical malaria had increased odds of being anaemic(adjusted odds ratio[aOR]=4.63,95%confidence interval[Cf]:2.90-7.40),P<0.0001.Conclusions:This study found that clinical malaria increased the risk of anaemia in PSC Thus,elimination of malariacausing parasites from the PSCs blood should be rapid and complete in order to prevent the progression of uncomplicated malaria to a chronic infection that can lead to the development of malaria-related anaemia.
