Children who report episodes of binge eating gain more weight than do children not reporting binge eating. However, how binge eating affects children's food intake at meals is unknown.
We compared the energy intake and postmeal satiety of children with and without a history of binge eating during buffet meals.
Sixty overweight children aged 6-12 y were categorized into those reporting past binge-eating episodes (n = 10) and those reporting no such episodes (n = 50). Children selected lunch twice from a multiple-item, 9835 kcal, buffet meal: after an overnight fast and after a standardized breakfast. Children ate ad libitum, until they reported they were full. The main outcome measures were energy intake during meals and duration of postmeal satiety, after adjustment for covariates, including age, race, sex, socioeconomic status, and body composition.
After the overnight fast, children in the binge-eating group consumed more energy [x (+/-SD): 1748 +/- 581 compared with 1309 +/- 595 kcal; P = 0.04] and exhibited a shorter satiety duration (194 +/- 84 compared with 262 +/- 89 min; P = 0.03) than did children in the non-binge-eating group. After the standardized breakfast, binge-eating children reported a shorter satiety duration (75 +/- 62 compared with 132 +/- 62 min; P = 0.01) and consumed more energy at the postbreakfast meal (1874 +/- 560 compared with 1275 +/- 566 kcal; P = 0.004).
The ability to consume large quantities of palatable foods, coupled with decreased subsequent satiety, may play a role in the greater weight gain found in binge-eating children.
报告有暴饮暴食发作的儿童比未报告有暴饮暴食的儿童体重增加更多。然而，暴饮暴食如何影响儿童进餐时的食物摄入量尚不清楚。
我们比较了有暴饮暴食史和无暴饮暴食史的儿童在自助餐时的能量摄入和餐后饱腹感。
将60名6至12岁的超重儿童分为报告过去有暴饮暴食发作的儿童（n = 10）和未报告有此类发作的儿童（n = 50）。儿童从一份包含多项食物、能量为9835千卡的自助餐中选择两次午餐：一次是在禁食过夜后，另一次是在标准早餐后。儿童随意进食，直到他们报告吃饱为止。主要观察指标是在调整协变量（包括年龄、种族、性别、社会经济地位和身体成分）后，进餐时的能量摄入和餐后饱腹感持续时间。
禁食过夜后，暴饮暴食组的儿童比非暴饮暴食组的儿童摄入更多能量[平均值（±标准差）：1748±581千卡，而后者为1309±595千卡；P = 0.04]，且饱腹感持续时间更短（194±84分钟，而后者为262±89分钟；P = 0.03）。标准早餐后，有暴饮暴食的儿童报告的饱腹感持续时间更短（75±62分钟，而后者为132±62分钟；P = 0.01），并且在早餐后进餐时摄入更多能量（1,874±560千卡，而后者为1,275±566千卡；P = 0.004）。
食用大量美味食物的能力，再加上随后饱腹感降低，可能在暴饮暴食儿童体重增加更多方面起作用。
