目的：本研究的目的是探讨是否看电视（TVV）提供了一个背景下的模式，零食培养超重的年轻女孩超重超重和非超重family.Research方法和程序：参与者是173个非西班牙裔白色女孩和他们的父母从宾夕法尼亚州中部，纵向评估时，女孩是5，7，9岁。采用路径分析来检验女孩的TVV、看电视时吃零食、吃零食频率、能量密集型零食的脂肪摄入量以及女孩5岁至9岁前体质量（BMI）增加之间的关系模式。结果：在超重和非超重家庭中，看电视越多的女孩在电视前吃的零食越多。在父母都不超重的家庭中，看电视是女孩体重指数增加的唯一重要预测因素。在父母一方或双方超重的家庭中，看电视越多的女孩吃零食越频繁，吃零食越频繁的女孩从能量密集的零食中摄入的脂肪越多，这预示着她们的BMI从5岁到9岁会增加。TVV并没有直接预测女孩的体重指数的增加，女孩超重family.Discussion：本研究的结果支持和扩展以前的研究结果表明，过度看电视和吃零食的模式是儿童超重的发展的危险因素，然而，模式的关系可能会有所不同，根据父母的体重状况。对于超重的家庭，TVV可能提供了一个背景下，过量的零食消费，除了不活动。
Objective: The purpose of this study was to examine whether television viewing (TVV) provides a context for patterns of snacking fostering overweight in young girls from overweight and non-overweight families.Research Methods and Procedures: Participants were 173 non-Hispanic white girls and their parents from central Pennsylvania, assessed longitudinally when girls were 5, 7, and 9 years old. Path analysis was used to test patterns of relationships among girls' TVV, snacking while watching television, snacking frequency, fat intake from energy-dense snack food, and girls' increase in body mass in ex (BMI) from age 5 to 9.Results: In both overweight and non-overweight families, girls who watched more television consumed more snacks in front of the television. In families where neither parent was overweight, television viewing was the only significant predictor of girls' increase in BMI. In families where one or both parents were overweight, girls who watched more television snacked more frequently, and girls who snacked more frequently had higher intakes of fat from energy-dense snacks, which,predicted their increase in BMI from age 5 to 9. TVV did not directly predict girls' increase in BMI in girls from overweight families.Discussion: The results of this study support and extend previous findings that have shown that excessive television viewing and snacking patterns are risk factors for the development of overweight in children; however, patterns of relationships may differ based on parental weight status. For overweight families, TVV may provide a context for excessive snack consumption, in addition to inactivity.
