Introduction: The reduction of waist-height ratio, which is related to the accumulation of central body fat, is directly related to fasting plasma glucos

Objective: To evaluate the correlation between waistheight and fasting plasma glucose in pre and postoperative bariatric surgery

Methods: Longitudinal study of a series of cases, with 50 patients submitted to Roux-en-Y gastric bypass. The variables of weight, height, body mass index, waist circumference, percentage of weight loss and fasting plasma glucose were obtained the day before surgery and at 1 and 3 months after. Results were expressed as mean and standard deviation. Continuous variables were tested for normality by the Kolmogorov-Smirnov test. The t-test of paired student was used to compare the means at the different moments evaluated. The verification of possible correlations was performed by the Pearson correlation test. It was adopted p <0.05

Results and Discussion: The patients’ age was 42.9 ± 10.5 years, with 78% being female. FPG reduced from 126.22 ± 48.12 mg / dL preoperatively to 92.79 ± 17.81 mg / dL after three months of surgery (p <0.002), while the waist-to-height ratio decreased from 0.77 ± 0.09 cm to 0.69 ± 0.09 cm (p <0.0001) in the same period. The percentage of weight loss reached after the third surgical month was 17.91 ± 3.47%.

Conclusion: In the postoperative period there was a rapid normalization of glycemia, as well as a significant reduction of the WHtR. However, these variables were not correlated in the different moments evaluated.
