目的：为了评估是否零食的摄入量与儿童和青少年的体重变化有关，方法：前瞻性研究8203名女孩和6774名男孩，9-14岁，在1996年，在一个正在进行的队列研究谁完成了至少两份问卷，1996年和1999年之间。零食的摄入量在1996-1998年进行了评估，专门为儿童和青少年设计的经验证的食物频率问卷。结果测量是年龄和性别特异性的体重指数（BMI）的z分数的变化。结果：在整个研究期间，男孩比女孩消耗更多的零食。在控制了坦纳发育阶段、年龄、身高变化、活动和不活动后，男孩中零食摄入量与随后的BMI z评分变化之间没有关系（β = -0.004），但零食摄入量与BMI z评分呈弱负相关（β =-0.007，P
OBJECTIVE: To assess whether intake of snack foods was associated with weight change among children and adolescents.METHODS: Prospective study of 8203 girls and 6774 boys, 9-14 y of age in 1996, in an ongoing cohort study who completed at least two questionnaires between 1996 and 1999. Intake of snack foods was assessed in 1996-1998 with a validated food frequency questionnaire designed specifically for children and adolescents. The outcome measure was change in age- and gender-specific z-score of body mass index (BMI).RESULTS: Boys consumed more snack foods than girls during the entire study period. After controlling for Tanner stage of development, age, height change, activity, and inactivity, there was no relation between intake of snack foods and subsequent changes in BMI z-score among the boys (beta= -0.004), but snack foods had a weak inverse association (beta= -0.007, P
