To identify causes of preterm delivery and intrauterine growth retardation (IUGR) in a malaria endemic region of Papua New Guinea.
Independent predictors of preterm delivery and birthweight in term infants were identified using multiple regression analysis in a prospective study of 987 singleton live births delivered in Madang Hospital.
Overall, Plasmodium falciparum infection of the placenta was associated with a reduction in birthweight of 130 g. Malaria was significantly more common in primigravidae than multigravidae and probably contributed to both preterm delivery and IUGR. Maternal haemoglobin concentrations were significantly lower in malaria infected than noninfected women and reduced haemoglobin was the main determinant of preterm delivery. Poorer maternal nutritional status and smoking were associated with both prematurity and IUGR. Greater antenatal clinic attendance predicted increased birthweight in term infants.
Protection against malaria during pregnancy, especially in primigravidae, improved nutrition in women and discouragement of smoking would probably reduce both preterm delivery and IUGR. Greater use of existing antenatal clinics might increase birthweight in term infants.
确定巴布亚新几内亚疟疾流行地区早产和宫内生长受限(IUGR)的原因。
在对马当医院分娩的987例单胎活产进行的前瞻性研究中,采用多元回归分析确定足月儿早产和出生体重的独立预测因素。
总体而言,胎盘恶性疟原虫感染与出生体重降低130克有关。疟疾在初产妇中比经产妇中更为常见,可能导致早产和宫内生长受限。感染疟疾的孕妇血红蛋白浓度显著低于未感染的孕妇,血红蛋白降低是早产的主要决定因素。孕妇营养状况较差和吸烟与早产和宫内生长受限均有关。更多地到产前诊所就诊可预测足月儿出生体重增加。
孕期预防疟疾,尤其是在初产妇中,改善妇女营养并劝阻吸烟可能会减少早产和宫内生长受限。更多地利用现有的产前诊所可能会增加足月儿的出生体重。
