Low birth weight (LBW), anaemia and malaria are common in Papua New Guinean women.
To identify risk factors for LBW, anaemia and preterm delivery (PTD), pregnant women recruited into a cohort study in Madang, Papua New Guinea, were followed to delivery.
Of 470 women enrolled, delivery data were available for 328 (69.7%). By microscopy, 34.4% (113/328) of women had malaria parasitaemia at enrolment and 12.5% (41/328) at delivery; at each time point, PCR detected sub-microscopic parasitaemia in substantially more. Most infections were with Plasmodium falciparum; the remainder being predominantly P. vivax. Anaemia and smoking were associated with lower birth weight, and LBW (16.7%; 51/305) and PTD (21.8%; 63/290) were common. Histopathologically diagnosed chronic placental malaria was associated with LBW (adjusted odds ratio [aOR] 3.3; p=0.048) and PTD (aOR 4.2; p=0.01). Lack of maternal education predisposed to PTD. Sub-microscopic parasitaemia at delivery appeared to increase the risk of LBW. Of the genetic polymorphisms, Southeast Asian ovalocytosis, α(+)-thalassaemia and complement receptor 1 (CR1) deficiency, a CR1 heterozygous genotype was associated with decreased risk of anaemia and substantial but non-significant effects were noted in other comparisons.
In coastal Papua New Guinea, malaria and anaemia are important causes of adverse pregnancy outcomes.
低出生体重、贫血和疟疾在巴布亚新几内亚女性中很常见。
为了确定低出生体重、贫血和早产的风险因素,在巴布亚新几内亚马当招募进入队列研究的孕妇被随访至分娩。
在登记的470名女性中,有328名(69.7%)有分娩数据。通过显微镜检查,34.4%(113/328)的女性在登记时患有疟疾寄生虫血症,12.5%(41/328)在分娩时患有;在每个时间点,聚合酶链反应检测到的亚显微镜下寄生虫血症更多。大多数感染是由恶性疟原虫引起的;其余主要是间日疟原虫。贫血和吸烟与较低的出生体重有关,低出生体重(16.7%;51/305)和早产(21.8%;63/290)很常见。组织病理学诊断的慢性胎盘疟疾与低出生体重(调整优势比[aOR]3.3;p = 0.048)和早产(aOR 4.2;p = 0.01)有关。母亲缺乏教育易导致早产。分娩时的亚显微镜下寄生虫血症似乎会增加低出生体重的风险。在基因多态性方面,东南亚椭圆形红细胞增多症、α(+)-地中海贫血和补体受体1(CR1)缺乏症中,CR1杂合基因型与贫血风险降低有关,在其他比较中观察到显著但不显著的影响。
在巴布亚新几内亚沿海地区,疟疾和贫血是不良妊娠结局的重要原因。
