2012—2016年秦山核电基地周边地区出生缺陷发生状况调查

Investigation of birth defect situation in surrounding area of Qinshan nuclear power base from 2012 to 2016

目的:了解秦山核电站周边地区海盐县新生儿出生缺陷情况。方法:收集2012—2016年海盐县常住人口的孕产妇和期间出生新生儿资料,统计新生儿出生缺陷率及变化,比较周边嘉兴市及不同户籍出生缺陷差异,分析不同年龄、职业、文化程度、孕次、户籍、居住地与核电直线距离孕妇出生缺陷发生差异及可能风险因素。结果:2012—2016年14789例围产儿中发生出生缺陷312例,出生缺陷率21.10‰,各年份出生缺陷率无差异,与嘉兴市出生缺陷发生率(23.40‰)比较无差异,不同户籍孕妇出生缺陷发生率无差异,不同年龄、职业、文化程度、孕次、户籍、居住地距核电直线距离孕妇新生儿出生缺陷率比较均未见差异(均P>0.05)。结论:秦山核电站正常运行26年后,未对其周边海盐县近5年新生儿出生缺陷发生带来变化影响。

Objective:To understand the situation of birth defect in surrounding area of Qinshan nuclear power base.Methods:The data of pregnant women and newborns during 2012 and 2016 in Haiyan county were collected.The rate and change of birth defect were analyzed.The difference of birth defect was compared between Haiyan county and Jiaxing city,and among women with different census register.According to age,occupation,education level,pregnancy time,household registration,and linear distance of residence from nuclear power,the difference and risk factors of birth defect of women in different groups were statistically analyzed.Results:During 2012 and 2016,there were 312 cases with birth defects in 14789 perinatal births,and the birth defect rate was 21.10‰,which had no significant different from that(23.40‰)of Jiaxing City.There were no significant difference in the birth defect rate among different years,and among the women with different age,occupation,education level,pregnancy times,household registration,and the linear distance from residence to nuclear power(P>0.05).Conclusion:After 26 years of normal operation of Qinshan Nuclear Power Station,it has no significantly adverse influence on the birth defect of Haiyan county in recent 5 years.
