Background: Malaria in pregnancy is a critical public health issue that can lead to severe adverse outcomes for both mother and fetus. This systematic review and meta-analysis evaluated the prevalence of adverse birth outcomes in malaria-infected pregnancies and examines their association with the condition.
Method: We searched databases up to January 30, 2024, for observational studies on pregnant women with malaria. Data were analyzed using a random-effects model to calculate pooled prevalence rates and risk ratios (RRs) for adverse outcomes, with statistical support from R software version 4.3.
Results: Thirty-one studies were included, showing high prevalence of low birth weight (LBW; 17.4 %), preterm birth (17.9 %), and small for gestational age (SGA; 16.1 %) in malaria-affected pregnancies. Infected mothers were significantly more likely to have LBW infants (RR = 1.755), preterm births (RR = 1.484), and SGA infants (RR = 1.554). The risk of stillbirth was not significantly increased (RR = 1.238).
Conclusion: Malaria in pregnancy significantly elevates the risk of LBW, preterm birth, and SGA, underscoring the need for effective malaria prevention and treatment strategies in endemic regions. Future research should aim to refine and implement these strategies to enhance maternal and neonatal health outcomes.
