Introduction:

metabolic syndrome is a group of metabolic abnormalities such as obesity, dyslipidemia, glucose intolerance and arterial hypertension. An experimental, longitudinal and prospective study was carried out in the Villa Clara Experimental Toxicology Unit from September 2016 to July 2019.

Objective:

to evaluate the changes in the growth of rat fetuses with metabolic syndrome, with respect to the control group.

Methods:

two groups with induced metabolic syndrome were created, one for control and the other for study. Weight, height and cranial diameters were the studied variables. The Excel 2010 program and SPSS version 15.0 for Windows and the Chi Square test were used, as well as the Monte Carlo significance as statistical decision.

Results:

rat fetuses with induced metabolic syndrome had greater weight and height.

Conclusions:

the metabolic syndrome influenced the weight and height gain in prenatal fetuses, increasing the probability of macrosomia at birth.
