Résumé
Information is scarce on long-term changes in energy intake (EI), dietary energy density (DED), and body composition in adolescents undergoing laparoscopic Roux-en-Y gastric bypass (RYGB). To investigate long-term changes in EI, DED, and body composition in adolescents after LRYGB. University hospitals, multicenter study, Sweden. Eighty-five adolescents (67% girls; mean ± standard deviation, age 16.0 ± 1.2 yr, body mass index 45.5 ± 6.1 kg/m Weight decreased 31%, 33%, and 28% at 1, 2, and 5 years after LRYGB (P < .001) while controls gained 13% over 5 years (P < .001). Dietary assessments were completed in 98%, 93%, 87%, and 75% at baseline and 1, 2, and 5 years, respectively, and in 65% of controls. Baseline EI (2558 kcal/d), decreased by 34%, 22%, and 10% after 1, 2, and 5 years (P < .05). DED decreased at 1 year (P = .03). Macronutrient distribution was not different from controls at 5 years, but EI and DED were 31% and 14% lower (P < .015). Fat, fat-free, and muscle mass decreased through 5 years after LRYGB (P < .001). Boys preserved muscle mass more than girls (P < .01). Adequate protein intake was associated with preservation of muscle mass (P = .003). In adolescents undergoing LRYGB EI remained 10% lower 5 years after surgery. Decreased EI and DED, rather than macronutrient distribution, are important factors in weight loss after surgery. Higher protein intake may facilitate preservation of muscle mass.

BACKGROUND
Information is scarce on long-term changes in energy intake (EI), dietary energy density (DED), and body composition in adolescents undergoing laparoscopic Roux-en-Y gastric bypass (RYGB).
OBJECTIVES
To investigate long-term changes in EI, DED, and body composition in adolescents after LRYGB.
SETTING
University hospitals, multicenter study, Sweden.
METHODS
Eighty-five adolescents (67% girls; mean ± standard deviation, age 16.0 ± 1.2 yr, body mass index 45.5 ± 6.1 kg/m
RESULTS
Weight decreased 31%, 33%, and 28% at 1, 2, and 5 years after LRYGB (P < .001) while controls gained 13% over 5 years (P < .001). Dietary assessments were completed in 98%, 93%, 87%, and 75% at baseline and 1, 2, and 5 years, respectively, and in 65% of controls. Baseline EI (2558 kcal/d), decreased by 34%, 22%, and 10% after 1, 2, and 5 years (P < .05). DED decreased at 1 year (P = .03). Macronutrient distribution was not different from controls at 5 years, but EI and DED were 31% and 14% lower (P < .015). Fat, fat-free, and muscle mass decreased through 5 years after LRYGB (P < .001). Boys preserved muscle mass more than girls (P < .01). Adequate protein intake was associated with preservation of muscle mass (P = .003).
CONCLUSIONS
In adolescents undergoing LRYGB EI remained 10% lower 5 years after surgery. Decreased EI and DED, rather than macronutrient distribution, are important factors in weight loss after surgery. Higher protein intake may facilitate preservation of muscle mass.
