应用环境流行病学的方法，对生活饮用水中放射性核素水平不同的两区妇女妊娠结局进行了调查，其结果是：高放射性饮水区与对照区妇女妊娠结局正常率分别为９００．２０‰，９３０．７７‰，经统计学检验，其差异具有高度显著性（Ｐ＜０．０１）；死胎死产率分别为２５．２８‰，１５．６６‰，早产率分别为２５．９５‰，２０．３６‰，经统计学检验，其差异具有显著性（Ｐ＜０．０１，Ｐ＜０．０５）；而高放射饮水区自然流产率（１６．６３‰）和低体重儿出生率（２７．２８‰）与对照区的自然流产率（２２．６８‰）和低体重儿出生率（１９．５３‰）相比，其差异无显著性（Ｐ＞０．０５，Ｐ＞０．０５）。结果提示：①两区妇女异常妊娠结局发生率与国内一般水平一致。②长期饮用高本底放射性饮水可对妇女妊娠结局产生明显的不良影响
Epidemiological methods were used to investigate the pregnancy outcomes of women in two districts with different levels of radionuclides in drinking water. The results showed that the normal pregnancy rates of women with high-level drinking water and control were respectively 900.20 ‰ , 930.77 ‰ respectively. The statistic tests showed that the differences were highly significant (P <0.01). The stillbirth rates of stillbirths were 25.28 ‰ and 15.66 ‰, respectively. The premature birth rates were 25.95 ‰, 20.36 ‰, the difference was statistically significant (P <0.01, P <0.05), while the spontaneous abortion rate (16.63 ‰) and low birth weight .28 ‰) had no significant difference with spontaneous abortion (22.68 ‰) and low birth weight (19.53 ‰) in control area (P> 0.05, P> 0.05). The results suggest that: ① The incidence of abnormal pregnancy outcomes in women in both regions is consistent with the general level in China. ② long-term consumption of high background radioactive drinking may have a significant adverse effect on women’s pregnancy outcomes
