Abstract
The relations between high risk babies and their mothers with high risk pregnancy, who admitted in the 2nd Tokyo National Hospital during recent three years were discussed.
The most significant factors as the high risk pregnancy were the toxicosis, anemia and placenta previa during pregnant stage.
The most significant factors of the babies who were born from high risk mothers were twin, prematurity, asphyxia, etc.
Among the low birth weight infant group, the frequency of the high risk pregnancy of their mothers were higher in the cases with lower birth weight and lower gestational week.
For the purpose to gain good prognosis of the high risk babies, the control of the high risk pregnancy and the transitional care of the babies since immediately soon after birth by neonatologists may be valuable
