Eating rates (bites per interval) and other meal behaviors (number of chews, sips, talks with a neighbor, and chews per bite) were observed for 30 normal and 30 overweight white preschool children in their school cafeterias. Children were classified according to weight (overweight or normal), age (1 1/2--2 years, 3--4 years, or 5--6 years) and sex. Analysis of variance revealed that overweight preschool children demonstrated a somewhat higher rate of distinctly fewer chews per bite. Boys showed increasing chew rates with increasing age. Talk rates also increased with age but were unrelated to sex or weight status. Sip rates were not significantly associated with age, sex, or weight status. These results support the hypothesis that overweight persons are characterized by an increased eating rate and show that it is apparent even around the time of first self-feeding.
在学校自助餐厅中，观察了30名正常体重和30名超重的白人学龄前儿童的进食速度（每段时间的咀嚼次数）和其他用餐行为（咀嚼次数、啜饮次数、与邻座交谈次数以及每口咀嚼次数）。儿童根据体重（超重或正常）、年龄（1.5 - 2岁、3 - 4岁或5 - 6岁）和性别进行分类。方差分析显示，超重的学龄前儿童每口咀嚼次数明显较少，但进食速度略高。男孩的咀嚼速度随着年龄增长而增加。交谈速度也随年龄增长而增加，但与性别或体重状况无关。啜饮速度与年龄、性别或体重状况均无显著关联。这些结果支持了超重者进食速度加快这一假说，并表明这种现象在首次自主进食时就已明显存在。
