背景：几项横断面研究报告称，体重越重的儿童吃早餐的次数越少。然而，没有纵向研究表明不吃早餐是否会导致体重过度增加。目的：调查不吃早餐是否与体脂变化有关。方法：1996年，来自美国各地的41.4万名9至14岁的男孩和女孩返回了年度邮寄问卷(1996-1999)，用于今日成长研究。我们分析了报告早餐频率的儿童在三个1岁时期的身体质量指数(BMI；kg/m(2))的变化。结果：报告从不吃早餐的儿童比几乎每天吃早餐的儿童能量摄入量低。身体活动越多的儿童能量摄入量越高，那些报告说看电视/视频和玩电子游戏的时间更多的儿童也是如此。与之前的研究一样，不吃早餐与超重有关，这是横截面的。然而，与几乎每天吃早餐的超重儿童相比，从不吃早餐的超重儿童在接下来的一年里体重指数下降了(男孩：-0.66公斤/米(2)(S.E.=0.22)；女孩：-0.50公斤/米(2)(S.E.=0.14))。但与几乎每天吃早餐的同龄人相比，从不吃早餐的正常体重儿童体重增加(男孩：+0.21公斤/米(2)(S.E.女生：+0.08 kg/m(2)(S，e=0.05)。早餐频率与自我报告的学业质量呈正相关。结论：从不吃早餐的超重儿童可能会减去体脂，而正常体重的儿童则不会。由于许多研究将不吃早餐与较穷的学者联系在一起，因此应该鼓励孩子们吃早餐。
BACKGROUND: Several cross-sectional studies reported that heavier children eat breakfast less often. However, no longitudinal studies have addressed whether skipping breakfast leads to excessive weight gain.OBJECTIVE: To investigate whether skipping breakfast was prospectively associated with changes in body fatness.METHODS: A cohort of 414 000 boys and girls from all over the US, 9- to 14-y-old in 1996, returned annual mailed questionnaires (1996 - 1999) for the Growing Up Today Study. We analyzed change in body mass index (BMI; kg/m(2)) over three 1-y periods among children who reported breakfast frequency.RESULTS: Children who reported that they never eat breakfast had lower energy intakes than those who eat breakfast nearly every day. Children who were more physically active reported higher energy intakes, as did those who reported more time watching television/ videos and playing videogames. Like previous studies, skipping breakfast was associated with overweight, cross-sectionally. However, overweight children who never ate breakfast lost BMI over the following year compared to overweight children who ate breakfast nearly every day (boys: - 0.66 kg/m(2) (s.e. = 0.22); girls: - 0.50 kg/m(2) (s.e. = 0.14)). But normal weight children who never ate breakfast gained weight relative to peers who ate breakfast nearly every day ( boys: + 0.21 kg/m(2) (s.e. = 0.13); girls: + 0.08 kg/m(2) (s. e. = 0.05)). Breakfast frequency was positively correlated with self-reported quality of schoolwork.CONCLUSIONS: Overweight children who never eat breakfast may lose body fat, but normal weight children do not. Since numerous studies link skipping breakfast to poorer academics, children should be encouraged to eat breakfast.
