RESUMO
BACKGROUND: The aim of this study was to correlate the connection between self-management behaviors and anthropometric indices after Roux-en-Y gastric bypass (RYGB). METHODS: A sample of 180 patients suffering from obesity were treated with RYGB in 2019; 6 and 18 months after surgery, anthropometric indices, including weight, waist circumference, waist- to-height ratio, body mass index (BMI), and waist-to-hip ratio, were gauged, and participants completed the post-bariatric surgery self-management behaviors questionnaire. RESULTS: Correlation matrix results showed that all anthropometric indices had a significant positive relationship with self-management behaviors after RYGB; the results of the 18-month post-surgical follow-up exhibited no significant difference between anthropometric indices and self-management behaviors, 6 and 18 months after surgery. CONCLUSION: Therefore, the more self-management behaviors increase, the greater decrease in anthropometric indices will happen after RYGB.
