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大力审查，并收集了50多篇文章。因此，国际上多胞胎的增加和人工生殖治疗被确定为一个原因。因此，调查多胞胎的健康状况和生活环境是十分重要的。对0 ~ 3岁双胞胎母亲进行问卷调查。经母亲同意，以自我为导向的无签名问卷通过东京市区内的保健中心和自助团体发放。为了保护隐私，回答的问卷会在信封里更正，或者之后邮寄给研究人员。27位母亲回答了调查问卷。其中雄性7对，雌性10对，雌雄混合10对。26位母亲回答说，当她们遇到麻烦时，她们会向别人咨询。被推荐的人被问及多个问题。20位母亲咨询了配偶（伴侣），14位母亲咨询了自己的母亲或婆婆，11位母亲咨询了朋友。13位母亲回答说咨询是有帮助的。被问及对儿童保育提供物质支助的频率。84.6%的配偶（伴侣）几乎每天都帮助照看孩子。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，最常征求配偶（伴侣）的意见并要求支持。然而，被评估为最有帮助的人是他们自己的母亲或岳母。因此，即使频率低于配偶（伴侣），他们的母亲对双胞胎母亲的帮助也最大。

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.
