Estados de comportamiento intraútero en los hijos de madres con diabetes tipo 1

Abstract

ObjectiveTo establish to possible existence of differences in fetal neurological devolopment through analysis of the characteristics of fetal behavioral states in diabetic pregnancies Material and methodWe compared the results obtained in a control group, composed by 15 pregnant women with physiological pregnancy and another group composed by 15 pregnant women with type 1 diabetes. Gestacional age at the time of study was ≥ 37 and ≤ 41 weeks. Ocular activity, body movements and patterns of fetal cardiac frequency were sumultaneously recorder for 1 h using ultrasonography and kinetocardiography. The time spent by the fetuses in behavioral or coincident states, the ability to establish stable behavioral states and the number of changes in state (behavioral stability) were evaluated ResultsThe time spent by the fetuses in a state of deep sleep (F1) was significantly lower in the fetuses of diabetic women at 38 weeks' gestation. The duration of periods of behavioral incoordination (F5) was, in contrast, higner in this group and differences between groups were statustucally significant at 36-37 weeks. The number of changes in state was higher in the fetuses of diabetic women than in controls ConclusionsType 1 diabetes is associated with a lower ability to establish stable behavioral states in the fetuses of fiabetic mothers
