乳児の一時的体重停滞に関する衛生学的研究

There have been many works concerning health indicators for babies, but we can not find so many works which discuss about interrelations between socio-economical and cultural background of babies and health indicators used in the field of community health practice. The 420 objects were selected to be discussed among the babies at the area regulated by a certain health center, who were born during January 1st to December 31st in 1967. The author demonstrated that some life conditions of babies had very important impacts to a temporary loss or retardation of body weight among babies, such as birth weight, birth order, mother's age, mother's occupation and so forth. The results are as follows. 1) There were observed more frequently loss or retardation of body weight among babies with 2,500 gr or less and 3,501 gr or more birth weight. 2) In connection with birth order, there were observed less loss or retardation of body weight among the first born babies than others. 3) A group of mothers from 25 to 32 of ages had less babies of temporary loss or retardation of body weight than other groups. 4) The author pointed out that the younger mother she was, the more often her baby had loss or retardation of body weight during its weaning period. 5) There were observed more temporary loss or retardation of body weight among bosom fed babies, especially whose mother had engaged to agricultural work all day long than others. 6) Public health nurses were apt to find medical reasons only and miss socio-economical and cultural background for temporary loss or retardation of body weight among babies.
