摘要
为评价铅对接触男工妻子妊娠结局的影响,对387名接触工人和575名非接触工人进行了调查。接触组和对照组男工妻子的人工流产率,分别为20.2％和22.9％,无显著性差异(P>0.05);接触组男工妻子的自然流产率和围产儿死亡率均高于对照组,接触组分别为10.3％和37.7‰。对照组分别为4.6％和12.0‰。(RR分别为2.23和3.14),有显著性差异(P<0.05);接触组男工妻子中有自然流产史的人数所占比例亦明显高于对照组,前者为12.1％,后者为6.4％(P<0.05)。多因素分析表明:自然流产和子女出生体重与接触铅、接触工龄和婚育年龄有关。
The rates of induced abortion in exposed and non-exposed groups were 20.2 and 22.9%, respectively, and there existed no significant difference between the two groups (P>0.05).The rates of spontaneous abortion and perinatal mortality ratio, however,were 10.3% and 37.7‰ in exposed workers, and were much higher than those in non-exposed group (4.6% and 12.0%, respectively) The differences were statistically significant (P<0.05) . The proportion of women with one or more time of experience of spontaneous abortion in exposed group was 12,1%, and was also significantly (P<0.05) higher than that of non-exposed group(6.4%).Multiple stepwise liner regression and Logistic regression there were an remarkable correlation between the birth weight of newborn, span-taneous abortion or babies with birth weight less that 2500g and exposure, ages of the couple at delivery (P<0.05)
