Background. In sub-Saharan Africa, the intermittent preventive treatment of malaria in pregnancy using sulphadoxine pyrimethamine (IPTp-SP) strategy is recommended to limit malaria adverse effects on birth outcomes. Ten year after IPTp-SP was adopted in Burkina Faso, we assessed the magnitude and maternal factors of low birthweight (LBW) in Nanoro.Methods. A secondary analysis of data from a cross-sectional study was carried out in women who gave birth at Nanoro peripheral health centers using a binary multivariate logistic regression. Maternal socio-demographic factors, gyneco-obstetrical history and relevant medical characteristics were evaluated to identify associated factors. A p-value less than 0.05 was considered statistically significant.Results. Of 291 delivery records examined, 14 % of women received three or more doses of SP while 80% used bed nets the night before their admission for delivery. Malaria was detected in 36.1% and anemia in 52.9% of women. The average neonate...

The present study was a cross-sectional, case-control study designed to evaluate the prevalence of low birth weight (LBW) babies among pregnant women, attending antenatal clinics in some private and public hospitals in Anambra Eastern Nigeria. Altogether, 700 pregnant women aged 17 by voluntary participation between January 2012 and March 2013. Blood samples were collected by venepuncture under sterile conditions and examined for malaria parasites using rapid immunoassay method and thick and thin sme methods respectively. The babies' birth weights were extracted from the hospital records. The result showed that the prevalence rate of malaria among pregnant women was 73.1% while the prevalence rate of low birth weight babies was 6.6%. The birth weight of the babies ranged from 0.4-4.6Kg and all the LBW babies were from malaria infected mothers. The study concludes that malaria is a significant contributor to low birth weight babies among pregnant women in Anambra State, Nigeria. ...

Background: A prospective study aiming at assessing the effect of adding a third dose sulphadoxinepyrimethamine (SP) to the standard two-dose intermittent preventive treatment for pregnant women was carried out in Hounde, Burkina Faso, between March 2006 and July 2008. Pregnant women were identified as earlier as possible during pregnancy through a network of home visitors, referred to the health facilities for inclusion and followed up until delivery. Methods: Study participants were enrolled at antenatal care (ANC) visits and randomized to receive either two or three doses of SP at the appropriate time. Women were visited daily and a blood slide was collected when there was fever (body temperature > 37.5°C) or history of fever. Women were encouraged to attend ANC and deliver in the health centre, where the newborn was examined and weighed. The timing and frequency of malaria infection was analysed in relation to the risk of low birth weight, maternal anaemia and perinatal mortality. Results: Data on birth weight and haemoglobin were available for 1,034 women. The incidence of malaria infections was significantly lower in women having received three instead of two doses of SP. Occurrence of first malaria infection during the first or second trimester was associated with a higher risk of low birth weight: incidence rate ratios of 3.56 (p < 0.001) and 1.72 (p = 0.034), respectively. After adjusting for possible confounding factors, the risk remained significantly higher for the infection in the first trimester of pregnancy (adjusted incidence rate ratio = 2.07, p = 0.002). The risk of maternal anaemia and perinatal mortality was not associated with the timing of first malaria infection. Conclusion: Malaria infection during first trimester of pregnancy is associated to a higher risk of low birth weight. Women should be encouraged to use long-lasting insecticidal nets before and throughout their pregnancy.
Malaria is caused by protozoa of the genus Plasmodium and remains a major public health burden in Sub-Saharan Africa. Its prevalence varies between 9 to 18% with harmful consequences to both the mother and her baby, including adverse pregnancy outcomes such low birth weight, high morbidity, and mortality. However, effective antenatal strategies for improving maternal and child health outcomes through the prevention, early detection, and treatment of malaria in pregnancy, are still lacking in resource-constrained settings. Here, we sought to determine the predictors of low birth weight in pregnant women with malaria in a cohort study in Webuye hospital. Prior to the enrollment of 140 participants, permission was sought from relevant institutions and consent from the participants. Malaria test was conducted either with microscopy or rapid test, and then the cohort splits into malaria positive and negative followed up from the first antenatal visit (March 2022) and delivery (December 2...

Background: The weekly chemoprophylaxis of malaria during pregnancy with chloroquine (CQ) has become problematic with the increasing resistance of Plasmodium falciparum to this drug. There was a need to test the benefits of new strategies over the classical chemoprophylaxis. This study was conducted to provide data to the National Malarial Control Programme for an evidence-based policy change decision making process. It compares the efficacy of two IPT regimens, using chloroquine (CQ) or sulphadoxine/pyrimethamine (SP), with the classical chemoprophylaxis regimen using CQ in reducing the adverse outcomes of malaria infection, for the mother and the foetus. Methods: Pregnant women attending the first antenatal care visit were randomly assigned to one of the three treatment regimens. They were subsequently followed up till delivery. Maternal, placental and cord blood samples were obtained upon delivery to check for P. falciparum infection. Results: A total of 648 pregnant women were enrolled in the study. Delivery outcome were available for 423 of them. Peripheral maternal P. falciparum infection at delivery was found in 25.8% of the women. The proportion of women with maternal infection was significantly lower in the IPTp/SP group than in the CQ group (P << 0.000). The prevalence of placental malaria was 18.8% in the CWC/CQ group; 15.9% in the IPTp/CQ group and 10.6% in the IPTp/SP group. The incidence of LBW (weigth < 2,500 g) was significantly higher among infants of mothers in the CWC/ CQ group (23.9%) as compared with those of mothers in the IPTp/CQ (15.6%) and IPTp/SP (11.6%) groups (p = 0.02) Conclusion: Intermittent preventive treatment with SP has shown clear superiority in reducing adverse outcomes at delivery, as compared with intermittent preventive treatment with CQ and classical chemoprophylaxis with CQ.

Low birthweight (LBW) is a worldwide problem that particularly affects developing countries. However, limited information is available on its magnitude in rural area of Burkina Faso. This study aimed to estimate the prevalence of low birthweight and to identify its associated factors in Nanoro health district. A secondary analysis of data collected during a cross-sectional survey was conducted to assess the prevalence of low birthweight in Nanoro health and demographic surveillance system area (HDSS). Maternal characteristics extracted from antenatal care books or by interview, completed by malaria diagnosis were examined through a multi-level logistic regression to estimate odd-ratios of association with low birthweight. Significance level was set at 5%. Of the 291 neonates examined, the prevalence of low birthweight was 12%. After adjustment for socio-demographic, obstetric and malaria prevention variables, being primigravid (OR = 8.84, [95% CI: 3.72–21.01]), or multigravid with h...

To estimate the impact of hypothetical antimalarial and nutritional interventions (which reduce the prevalence of low midupper arm circumference [MUAC]) on the incidence of low birth weight (LBW). We analyzed data from 14 633 pregnancies from 13 studies conducted across Africa and the Western Pacific from 1996 to 2015. We calculated population intervention effects for increasing intermittent preventive therapy in pregnancy (IPTp), full coverage with bed nets, reduction in malaria infection at delivery, and reductions in the prevalence of low MUAC. We estimated that, compared with observed IPTp use, administering 3 or more doses of IPTp to all women would decrease the incidence of LBW from 9.9% to 6.9% (risk difference = 3.0%; 95% confidence interval = 1.7%, 4.0%). The intervention effects for eliminating malaria at delivery, increasing bed net ownership, and decreasing low MUAC prevalence were all modest. Increasing IPTp uptake to at least 3 doses could decrease the incidence of LBW...
