深圳市宝安区先天性畸形的前期监测研究

目的：为了解深圳市宝安区先天性畸形的发病情况和分布特征，为进一步研究提供线索和参考资料。方法：我们于1997年1月－1999年12月，对宝安区住院分娩的34613例围产儿进行了先天性畸形监测研究，对检出的269例畸形儿进行了流行病学分析。结果：宝安区先天性畸形的总发生率为77．72／万，常住和流动人口中先天性畸形的发生率分别为69．65／万、80．33／万。常住人口中先天性畸形发生率最高的镇为石岩（100．00／万）；其次为观澜（93．21／万）；最低的为光明（未监侧到）。先天性畸形的发生无性别差异，其中发病居前四位的畸形依次为：大腹儿，（Hb病），短肢或缺肢畸形，先天性脑积水，唇裂合并腭裂。结论：尽管宝安区先天性畸形的发生率比国内外报道的要低，但发生规律有自己的特点，应引起重视和进一步研究。
