OBJECTIVE:

To compare the fetal maternal outcomes in patients with gestational diabetes detected in the first and second half of pregnancy.

MATERIALS AND METHODS:

An observational, retrospective and analytical study was carried out including all patients with gestational diabetes treated at the Women's Hospital of Mexico City in the years 2014 to 2017. Were divided into two groups, group 1 inserted those patients diagnosed between 13 and 20.6 weeks of gestation and 2 with subsequent diagnosis, the main maternal and fetal complications were identified and compared. The results analysis included central trend measures, Student's t and square Chi.

RESULTS:

495 patients were included; Group 1 was composed of 147 pregnant women and group 2 of 312. Maternal complications such as hypertensive disease of pregnancy (32.7 vs 17.6% p 0.001), hyperthyroidism and hypothyroidism (7.5 vs 1.6% p 0.001) were more frequent at the group 1. The birth weight (3054 ± 718.4 vs. 3156 ± 555.7 g. p 0.04), height (48.9 ± 3.49 vs 49.2 ± 2.7 cm p 0.05) and Capurro rating (37.9 ± 2.5 vs 38.2 ± 1.4 weeks p 0.01) were greater in infants in Group 2.

CONCLUSION:

The maternal fetal outcome in patients with gestational diabetes are modified by gestational age at the time of diagnosis, so greater emphasis should be placed on the timely detection of these complications in order to reduce the impact of gestational diabetes in the mother's binomial.
