Introduction:

Fetal macrosomia is a pregnancy condition that generates short, medium and long-term complications for the fetus, newborn and mother.

Objectives:

To determine the maternal factors associated with fetal macrosomia according to the 2020 National Demographic and Family Health.

Methods:

Observational, retrospective, analytical, cross-sectional study based on the ENDES survey in 2020 using data from 5096 women aged 12-49 who met the established criteria. For the statistical analysis, SPSS version 25 was used, the corrected F test for complex samples, and a significance level of less than 0.05.

Results:

The prevalence of fetal macrosomia is 7.5%. The multivariate analysis found that, within the personal factors, maternal age has a significant association with fetal macrosomia (RPa 1.04, 95% CI 1.008 - 1.078). Of the pathological factors, maternal obesity has a significant association with fetal macrosomia (RPa 1.05, 95% CI 1.027 - 1.080). Of the social and demographic factors associated with fetal macrosomia, none of the variables described show a significant association.

Conclusion:

It was determined that maternal age over 34 and maternal obesity are associated with a higher prevalence of fetal macrosomia.
