A birthweight nomogram for Africa, as a malaria-control indicator.
1999
Low birthweight (LBW) attributable to malaria in pregnancy is a significant risk for millions in Africa. Infants born to primigravidae are at greatest risk and it is proposed that this excess risk can be used as a simple indicator of malaria transmission and exposure in pregnant women in Africa. Birthweight data from different regions in 11 malarious and three non-malarious African countries were investigated. A regression analysis of the excess risk of low birthweight in first pregnancies, compared with later ones, was completed and interpreted in relation to malaria-transmission intensities. The aim was to develop a simple birthweight chart (nomogram) as a tool for monitoring malaria transmission or malaria control in pregnancy. Low-birthweight risk in first pregnancies was associated with levels of malaria-transmission intensity amongst different African countries. The nomogram distinguished longitudinal changes in malaria exposure, related to season and changes in antimalarial-drug policy. Malaria is ...
