To study the incidence, types, and sites of neural tube defects (NTDs) and its associated maternal and environmental variables.
All preterm and full term live and stillborn babies delivered at Al-Ramadi Maternity and Children's Hospital, Al-Anbar Governorate, Iraq, from the 1st of November 2007 to the 1st of November 2008 were examined for gender, gestational age, NTDs, and associated congenital malformations. Mother's data included age, parity, consanguinity, education, antenatal care, previous medical illnesses, other NTDs history, folic acid supplementation, and diagnostic ultrasound. Incidence was calculated per 1000 births.
During the study, 33 infants were delivered with NTDs, giving an incidence of 3.3/1000 births. Most were of myelomeningocele and anencephaly types, and thoracolumbar and lumbosacral sites. Two-thirds of the cases found were from consanguineous marriage, 12 NTD's mothers took folic acid during their pregnancy, while none of them received the drug during the periconceptional period. Three mothers had another NTD affected babies before, and mothers 25-34 years old produced most of the NTD deliveries than any other age groups.
The NTDs incidence is still high compared with developed, and some developing countries. High consanguinity marriage and 100% lack of periconceptional folic acid intake needs further study considerations to reduce such morbid and mortal anomalies.
研究神经管缺陷(NTDs)的发病率、类型、部位及其相关的母体和环境变量。
对2007年11月1日至2008年11月1日在伊拉克安巴尔省拉马迪妇产儿童医院分娩的所有早产和足月活产及死产婴儿进行性别、孕周、NTDs及相关先天性畸形检查。母亲的数据包括年龄、产次、近亲结婚情况、教育程度、产前护理、既往病史、其他NTDs病史、叶酸补充情况及诊断性超声检查。发病率按每1000例出生计算。
研究期间,有33例婴儿患有NTDs,发病率为3.3/1000例出生。大多数为脊髓脊膜膨出和无脑儿类型,部位在胸腰段和腰骶段。发现的病例中有三分之二来自近亲结婚,12例NTDs患儿的母亲在孕期服用了叶酸,但在受孕前阶段均未服用该药物。3名母亲之前有过其他NTDs患儿,25 - 34岁的母亲所分娩的NTDs患儿比其他任何年龄组都多。
与发达国家和一些发展中国家相比,NTDs的发病率仍然很高。高近亲结婚率和受孕前叶酸摄入量100%缺乏需要进一步研究以减少此类致残和致死性异常情况。
