自78年9月1日至80年8月31日,通过对山西省畸胎率的回顾性调查,发现畸胎率总体率的95％可信区间为28.97‰～26.07‰,高于第一世界水平。畸胎率高的原因,与孕期服某种药、孕期患某种病毒性疾病、近亲结婚、家族史、环境污染、环境微量元素的缺乏因素有联系。畸胎的性比例为1:0.72,男性大于女性。畸胎成活与死亡之比,神经系统畸形为1:1.36,其它畸形为1:0.088。而神经系统的畸胎率高达9.79％。且在畸形构成中亦占35.58％。
From September 1, 1978 to August 31, 1980, a retrospective survey of teratogenic rates in Shanxi Province found that the 95% confidence interval for the overall rate of teratogenic rates was 28.97 ‰ to 26.07 ‰, higher than the first World level. The reasons for the high rate of teratogenicity are related to some drugs during pregnancy, some viral diseases during pregnancy, close relatives’ marriage, family history, environmental pollution and lack of environmental trace elements. Teratogenic sex ratio of 1: 0.72, men than women. The ratio of teratogenicity to death, neurological deformity 1: 1.36, other deformities 1: 0.088. The nervous system teratogenic rate as high as 9.79%. And in the deformity also accounted for 35.58%.
