Cross-sectional data indicate an inverse relation between breakfast consumption and child weight. It has been suggested that skipping breakfast may adversely affect appetite in children, which could lead to overeating later in the day.
The aim of this study was to test the effects of consuming breakfast compared with omitting breakfast on appetite ratings and energy intake at subsequent meals in 8- to 10-y-old children.
Twenty-one children participated in 2 test visits during which they were served either a compulsory breakfast or no breakfast. On both visits, subjects were also served lunch, which was consumed ad libitum. Subjects rated their appetite throughout the morning; parents completed food records that captured children's intake for the remainder of the day.
There was no significant main effect of breakfast condition on energy intake at lunch (P = 0.36) or throughout the remainder of the day (P = 0.85). There was a significant main effect of breakfast condition (P = 0.04) on total daily energy intake, which indicated that on the day when the subjects did not eat breakfast, they consumed 362 fewer calories over the course of the day than when they did eat breakfast. On the day when no breakfast was served, subjects indicated that they were significantly hungrier, less full, and could consume more food before lunch than on the day when they did eat breakfast (P < 0.001).
Omitting breakfast affected children's appetite ratings but not their energy intake at subsequent meals. The dissonance between children's subjective ratings of prospective consumption and their actual intake should be further examined.
横断面数据表明,早餐的摄入与儿童体重呈反比。有人认为,不吃早餐可能会影响儿童的食欲,导致他们在一天中晚些时候暴饮暴食。
本研究旨在测试与不吃早餐相比,吃早餐对 8-10 岁儿童后续餐次的食欲评分和能量摄入的影响。
21 名儿童参加了 2 次测试访问,在这 2 次测试中,他们分别被提供了强制早餐或无早餐。在这两次访问中,还提供了午餐,供孩子们自由食用。研究对象在整个上午都对自己的食欲进行了评分;家长填写了记录,记录了孩子们当天剩余时间的饮食摄入情况。
早餐条件对午餐时(P = 0.36)或全天的能量摄入没有显著的主要影响(P = 0.85)。早餐条件有显著的主要影响(P = 0.04)对全天的总能量摄入,这表明当孩子们不吃早餐时,他们全天摄入的卡路里比吃早餐时少 362 卡路里。在没有提供早餐的那天,研究对象表示他们感到饥饿、饱腹感较低,并且可以在午餐前吃更多的食物,这比他们吃早餐的那天更明显(P < 0.001)。
不吃早餐影响了儿童的食欲评分,但不影响他们在后续餐次的能量摄入。应该进一步研究儿童对预期消费的主观评价与其实际摄入之间的不和谐。
