Abstract

Purpose

Pregnant women who have undergone bariatric surgery must be followed to ensure healthy mother-child nutritional status. This study aimed to compare weight status of mother-child dyad after maternal bariatric surgery in public and private Brazilian healthcare system units.

Materials and Methods

This retrospective matched case-control included 19 women who underwent Roux-en-Y gastric bypass surgery performed by the same private clinical surgical team and 19 age- and preoperative body mass index (BMI) matched patients from a public hospital. All 38 female patients reported a postoperative spontaneous pregnancy. The T test of independent samples and Pearson chi-square test were used to investigate inter-group differences.

Results

Patients in the private system were more frequently married (94.7% versus 68.4%, p = 0.036) and had a higher educational level (94.7% versus 36.8%, p = 0.01 for tertiary education) but lower BMI, compared with those in the public system (pre-gestational = 25.7 ± 3.2 versus 28.5 ± 5.0 kg/m2, p = 0.049; post-gestational = 24.6 ± 1.6 versus 29.0 ± 6.0 kg/m2, p = 0.040). The interval from bariatric surgery to conception was shorter among public system patients (21.1 ± 13.9 versus 43.4 ± 31.2 months, p = 0.009). In both groups, almost 90% of children were born at full term and with adequate weights.

Conclusion

Despite differences in the characteristics of public and private systems, the mother-child dyads in both groups achieved satisfactory post-bariatric surgery gestation outcomes. The type of medical system does not appear to influence pregnancy outcomes or neonatal weight status conditions.
