极度肥胖的青少年越来越多地接受限制饮食摄入的减肥手术。然而，目前还没有数据可以描述青少年肥胖患者术前和术后饮食中热量密度或成分的变化。评估接受减肥手术的青少年1年内饮食组成的变化。2005年8月至2008年3月，27名受试者（67%女性，77%白人，年龄16.7±1.4岁，基线体重指数（BMI） 60.1±14.1 kg/m2）在行腹腔镜Roux-en-Y胃旁路手术（RYGB）前一个月前瞻性纳入观察性队列研究。在基线（n=24）、术后2周（n=16）、3个月（n=11）和1年（n=9）记录三天的饮食摄入量。通过结构化访谈验证饮食记录数据，并与14-18岁的膳食参考摄入量（DRI）值进行比较。术后1年，BMI调整后的平均热量摄入为1015±182千卡/天，较基线降低35%。脂肪、蛋白质和碳水化合物摄入的比例与基线没有差异。然而，术后蛋白质摄入量低于推荐值。钙和纤维的摄入量也一直低于推荐值。补充钙和维生素B12增加了达到每日最低建议摄入量的可能性（p≤0.02）。RYGB后一年，青少年的热量摄入仍然受到限制，宏量营养素组成令人满意，但钙、纤维和蛋白质的摄入量低于理想水平。
Extremely obese adolescents are increasingly undergoing bariatric procedures, which restrict dietary intake. However, there are as yet no data available which describe the change in caloric density or composition of the adolescent bariatric patient’s diet pre- and post-operatively. Assess the 1-year change in dietary composition of adolescents undergoing bariatric surgery. Tertiary care children’s hospital Twenty-seven subjects [67% female, 77% white, age 16.7 ± 1.4 years, baseline body mass index (BMI) 60.1 ± 14.1 kg/m2] were prospectively enrolled into an observational cohort study one month prior to laparoscopic Roux-en-Y gastric bypass (RYGB) between August 2005 and March 2008. Three-day dietary intake was recorded at baseline (n=24), at 2 weeks (n=16), 3 months (n=11), and 1 year (n=9) post-operatively. Dietary record data were verified by structured interview and compared with Dietary Reference Intake (DRI) values for ages 14–18. By 1 year post-surgery, mean caloric intake adjusted for BMI was 1015 ± 182 kcal/day, a 35% reduction from baseline. The proportion of fat, protein and carbohydrate intake did not differ from baseline. However, protein intake was lower than recommended postoperatively. Calcium and fiber intake was also persistently lower than recommended. Calcium and vitamin B12 supplementation increased the likelihood of meeting daily minimal recommendations (p≤0.02). One year after RYGB, adolescents’ caloric intake remained restricted with satisfactory macronutrient composition, but with lower than desirable intake of calcium, fiber and protein.
