To determine the incidence of delivery of high birth weight (HBW) babies in Benin City and document their foetal outcome.
All babies with HBW (defined as birth weight 4000 g) were recruited into the study. The maternal records were examined for maternal age, parity, height, gestational weight gain and mode of delivery. The sexes, head circumferences and lengths at birth were documented. Foetal outcome such as stillbirth, birth asphyxia, Erb's palsy, fracture of the clavicles and the need for admission into the Special Care Baby Unit in HBW babies (study group) was compared with that of a control group.
The incidence of delivery of a HBW infant was 8.1% with a male preponderance. Maternal parity and age influenced the incidence. The highest incidence was among para 4 women and those aged between 35 and 39 years. The lowest incidence was among para zero and teenage women respectively. Women with a history of delivery of a previous baby with birth weight of 4000g, a gestational weight gain of 13-15 kg and a height >1.63 m had an increased tendency towards delivery of a HBW infant. High birth weight babies were at a higher risk of foetal death and delivery by Caesarean Section.
Incidence of delivery of HBW infant is relatively high in Benin-City. It is associated with increased rate of Caesarean delivery and foetal death.
确定贝宁城高出生体重（HBW）婴儿的分娩发生率，并记录其胎儿结局。
所有HBW婴儿（定义为出生体重≥4000g）均纳入本研究。检查产妇记录，了解产妇年龄、产次、身高、孕期体重增加情况及分娩方式。记录婴儿性别、出生时头围和身长。将HBW婴儿（研究组）的胎儿结局，如死产、出生窒息、臂丛神经麻痹、锁骨骨折以及入住特殊护理婴儿病房的需求，与对照组进行比较。
HBW婴儿的分娩发生率为8.1%，男性占多数。产妇产次和年龄影响发生率。发生率最高的是经产妇4及年龄在35至39岁之间的女性。发生率最低的分别是初产妇和青少年女性。既往有出生体重≥4000g婴儿分娩史、孕期体重增加13 - 15kg且身高>1.63m的女性，分娩HBW婴儿的倾向增加。高出生体重婴儿胎儿死亡和剖宫产分娩的风险更高。
贝宁城HBW婴儿的分娩发生率相对较高。它与剖宫产率和胎儿死亡率增加有关。
