Abstract

The Control Group was submitted to verbal instructions on the surgical procedure, routine of the institution. The Intervention Group, in addition to this routine, underwent an educational intervention performed by a nurse, weekly, from reading an educational booklet with information and clarifications about the perioperative period for three weeks. The Wilcoxon test was used for analysis to compare obesity indicators between collection times and the Mann-Whitney test to compare variables among groups.
Results
The variables weight reduction, body mass index, waist circumference, waist-to-height ratio and percentage of overweight increased in the Control Group and statistically significantly reduced in the Intervention Group.
