Abstract
Background:
Bariatric surgery is becoming more common for adolescents. This study aims to describe presurgery dietary intake in adolescents who underwent sleeve gastrectomy to determine whether there is a correlation between fruit and vegetable intake before surgery and weight loss, physical activity, and psychological measures postsurgery.
Methods:
Adolescents between 13 and 17 years old with a body–mass index (BMI) between 35 and 60 kg/m2 who received the sleeve gastrectomy procedure were recruited for the study. Weekly servings of fruits and vegetables reported during the initial consultation were collected and analyzed.
Results:
Mean age of participants (n = 13) was 16.8 years. We observed a moderate positive relationship between combined fruit and vegetable consumption (r = −0.60, p = 0.01) and particularly with fruit consumption alone (r = −0.66, p = 0.0003) with change in BMI at 6 months after surgery. There was also a significant positive relationship between combined fruit and vegetable intake and changes in appetite awareness 6 months postsurgery (r = 0.41, p = 0.05).
Conclusions:
This was the first study to examine the correlation between presurgical diet and weight loss postsurgery in adolescents. Dietary factors such as higher consumption of fruits and vegetables before surgery may help improve hunger/fullness awareness postsurgery.
