[A developmental study of low birth weight infants in 1986].

Evolution of the newborn infant weighing 1,000-1,499 g, was studied in 1986 in the "Mariana Grajales" Gynecologic and Obstetric Teaching Provincial Hospital, Department of Neonatology, Santa Clara. Data was obtained from the clinical histories of the newborns and of their mothers. A control group was selected in order to analyze and compare the causes of low birthweight, and as causes of it were determined age and height, and as associated diseases, urinary sepsis, anemia and toxemia of pregnancy. Premature rupture of membranes was significant. Half of the infants of the group under study was severe and moderately depressed. At the somatic evolution was observed a trend to increment and a high coefficient of correlation within the three variables under study. Main nursing actions offered fit up to the attention of these neonates.
