Abstract
For the purpose of getting the basic data on the mental support for the maternal, we researched the maternal mental states (depression, maternity blues, depression after childbirth) at the early stage of pregnancy (within 15 weeks) and after five days of childbirth and after a month. We investigated the change in the mental states and assessed their environmental factors. This research led them to conclude as follows: 1. The highest frequency of the maternal depressive state was in the early stages of pregnancy. And a month after comes next and then five days after. 2.For primiparas the frequency of depression was high at all stages. 3.The depressive state in the early stage of pregnancy had an effect on the mental states both after five days and after a month. 4.The depression after birth was strongly affected by the mental states after five days of childbirth.
