title: A review of the current state of malaria among pregnant women in Papua New Guinea.
abstract: Besides young children, pregnant women are at high risk of malaria in highly endemic countries. This paper reviews evidence from studies conducted in Papua New Guinea (PNG) in the last 20 years on the burden and prevention of malaria in pregnancy and highlights gaps in our knowledge of malaria in pregnancy in PNG. Overall, primigravidae were found to be at higher risk than multigravidae, with up to 40% of primigravidae but only 10-25% of multigravidae infected with Plasmodium falciparum at delivery. Such infections were found to be associated with a 128-145 g decrease in birthweight. Mean birthweights reported between 1980 and 2003 range from 2.58 to 2.72 kg in primigravidae and 2.84 to 3.09 kg in multigravidae, with 21% to 48% and 9% to 19% of babies born to primigravidae and multigravidae, respectively, of low birthweight (<2500 g). The negative impact of malaria in pregnancy is compounded by relatively low rates of antenatal coverage. The current PNG national treatment policy which prescribes a treatment course of first-line antimalarial treatment (currently chloroquine and sulphadoxine-pyrimethamine) at first antenatal clinic contact, followed by weekly chloroquine prophylaxis and iron and folate supplementation, may no longer be effective given the high levels of resistance to chloroquine in PNG and poor compliance. In order to reduce the burden of malaria in pregnancy in PNG, alternative methods of control such as insecticide-treated nets and intermittent preventive treatment in pregnancy (IPTp), as well as improved modes of delivery of maternal health interventions, are urgently needed.
