Comprehensive evaluation of subjective and objective health indicators and living environment among multiple births born in the area with high risk multiple pregnancies

对多胞胎及其风险的国际趋势进行了积极的审查，收集了50多篇文章。因此，国际上多胎分娩的增加和人工生殖疗法被确定为一个原因。因此，对多胎妊娠妇女的健康状况和生活环境进行调查具有重要意义。对0-3岁双胞胎母亲进行问卷调查。自我导向的未签名的问卷，通过东京都内的保健中心和自助团体的母亲的协议交付。为了保护隐私，调查问卷被放在信封里修改，或者事后邮寄给研究人员。27位母亲回答了问卷。其中7对为雄性，10对为雌性，10对为雌雄混合。26位母亲回答说，当她们遇到困难时，她们会向别人咨询。被转介人被问到多个问题。20名母亲咨询了她们的配偶（伴侣），14名母亲咨询了自己的母亲或婆婆，11名母亲咨询了她们的朋友。13位母亲回答说，咨询是有帮助的。询问了儿童保育的物质支持频率。84.6%的配偶（伴侣）几乎每天都帮助照顾孩子。73.1%的母亲认为这种支持很有帮助。大约80%的家庭是核心家庭。因此，配偶（伴侣）最常被咨询并要求支持。然而，被评价为最有帮助的人是他们自己的母亲或岳母。因此，即使频率小于配偶（伴侣），他们的母亲也显示出对双胞胎母亲的帮助最大。

International trends in multiple births and their risks were vigorously reviewed and more than 50 articles were collected. Accordingly, international increase in multiple births and artificial reproductive therapy as a cause were identified. Therefore it was thought to be important to investigate health status and living environment of multiple births. Mothers of twins with 0-3 years of age were investigated with questionnaire. Self-oriented unsigned questionnaires were delivered with agreement of mothers through health centers and self help groups within Tokyo metropolitan area. Answered questionnaires were corrected in envelope for protection of privacy or mailed to researchers afterward. Twenty seven mothers answered the questionnaires. Seven pairs were male, 10 pairs were female, and 10 pairs were mixed-sexed. Twenty six mothers answered that they consulted someone when they had trouble. Referred persons were asked by multiple questions. Twenty mothers consulted their spouse (partner), 14 mothers consulted their own mothers or mothers-in-law and 11 mothers consulted their friends. Thirteen mothers answered that consultation was helpful. Frequency of physical support of child care was asked. 84.6% of spouses (partners) helped the child care almost every day. 73.1% of mothers felt such support very helpful. Around 80 percent of families were nuclear families. Therefore spouses (partners) were most frequently consulted and demanded support. However, persons who were evaluated to be most helpful were their own mothers or mothers-in-law. So even if frequency was smaller than spouses (partners), their mothers revealed to be of the most help for the mothers of twins.
