| Research Abstract |
The aim of this study is to examine multilaterally the possibility of constructing population-based twin registry, especially focusing on young children, and preliminary create a systematic twin registry. The researcher considered following items ; 1.Vital statistics regarding multiple births. 2.Assisted reproductive technology and multiple births. 3.Twin registries in the world. 4.Social and psychological circumstances surrounding families with multiples. 5.Nation-wide social support for families with multiples in the world. Finally, public health problems associated with multiple births were summed up. Currently more than 1% of all births are multiples. However, little information regarding nurturing of multiples is available, in part because of the lack of a population-based registry of multiples. The majority of twin registries throughout the world seem to have been constructed primarily for genetic epidemiologic twin studies. It appears to be very difficult to achieve a high participation rate from families with very young children in Japan, particularly if researchers perform only a genetic twin study with no feedback for the participants. Offering information useful for the nurturing of multiples would be a strong incentive for the parents. Given this background, the construction of a population-based database of multiples in childhood at the prefectural level began. An exhaustive search for demographic information concerning families with multiples were performed, and at the same time tried to organize a human network to support such families. This registry aims not only to aid research on human genetics and maternal and child health, but also to contribute to the development of welfare programs for families with multiples. This strategy is welcomed by the many participants and other involved parties, and seems to be highly cost effective compared to other methods, for example using the information from Basic Resident Registration of municipalities.
