Introduction:

the increase of abdominal adipose tissue in early pregnancy causes metabolic changes that promote insulin resistance, which is linked to alterations in fetal growth detectable by ultrasonography.

Objective:

to determine the association of the variation of the adipose strata of the anterior abdominal wall with the presence of insulin resistance and with fetal biometry.

Methods:

longitudinal analytical study in a population of 144 normopoietic pregnant women, apparently healthy, with optimal reproductive age, nulliparous, belonging to the Polyclinic “Chiqui Gómez Lubián” of Santa Clara City. The sample was 123. Theoretical, empirical and statistical methods were used.

Results:

subcutaneous fat decreases as preperitoneal fat increases from the first to the second trimester, both expressed with greater intensity in pregnant women who did not have insulin resistance at the beginning of gestation. In the pregnant women who did not have insulin resistance, all the biometric variables decreased in the classification of fetuses appropriate for gestational age from the second to the third trimester and increased the frequencies of small and large fetuses, while in those who had insulin resistance, the cephalic circumference and the abdominal circumference showed stability in the identification of large fetuses.

Conclusions:

the lower variation of the adipose strata of the anterior abdominal wall is related to the presence of insulin resistance at the beginning of gestation in pregnant women in whom the biometric variable abdominal circumference is associated with the identification of large fetuses for gestational age from the second trimester.
