为了明确双胎儿童的脑性瘫痪患病率及其与脑性瘫痪的关联性，于１９９７ 年５ ～７ 月在江苏南部７ 个市对０ ～６ 岁儿童进行了现况普查。结果表明双胎儿脑瘫患病率为９７４ ‰（９５ ％ 可信限，６１５ ％ ～１３３３ ％ ） ，是单胎儿的６４ 倍（９５ ％ 可信限，４４ ～９３） 。如果按出生体重的实际测量进行分组，则低出生体重双胎儿的脑瘫患病率低于相同出生体重组别的单胎儿，而正常出生体重双胎儿的脑瘫患病率却高于相应的单胎儿；根据标准正态离差进行分组，则双胎儿脑瘫患病率在所有出生体重组均高于单胎儿，并随着出生体重的增加双胎儿的脑瘫患病危险性有增大之趋势。提示双胎是脑瘫独立的危险因素并且双胎导致脑瘫的危险性随着胎儿的成熟而呈增大趋势 To clarify the prevalence of cerebral palsy among twin children and their association with cerebral palsy, a current status survey of children aged 0-6 years was conducted in seven cities in southern Jiangsu from May to July 1997. The results showed that the prevalence of cerebral palsy in twin fetuses was 974 ‰ (95% confidence interval, 615% ~ 1333%), which was 64 times that of single fetus (95% confidence interval, 44 ~ 9  3). If grouping by actual measurements of birth weight, the prevalence of cerebral palsy in the low birth weight twins is lower than the single birth weight in the same birth weight group, whereas the prevalence of cerebral palsy in the normal birth weight twins is higher than in the corresponding single fetuses ; According to the standard deviation of normal group, the prevalence of bipolar cerebral palsy in all birth weight groups were higher than that of single fetus, and with the birth weight increased the risk of cerebral palsy in twin fetuses increased risk. Tip twins are independent risk factors for cerebral palsy and twins cause the risk of cerebral palsy increased with the maturity of the fetus
