目标。我们研究了吃饭时看电视和儿童食物消费模式之间的关系，以测试儿童的总体食物消费模式，包括通常没有广告的食物，是否会随着电视在正常用餐时间中的作用程度而系统地变化。来自华盛顿特区附近郊区的91对亲子通过广告和口碑招募参加了这项活动。孩子们上四年级、五年级或六年级。社会经济数据和有关电视使用的信息是在调查访谈期间收集的。对每个儿童进行的三次不连续的24小时饮食回忆被用来构建营养和食物摄入量结果变量。采用独立样本t检验比较两餐或两餐以上经常打开电视的家庭(n=41)和从未打开或仅在一顿饭中打开电视的家庭(n=50)儿童的平均食物和营养素摄入量。在控制社会经济因素和其他协变量的情况下，使用多元线性回归模型检验电视与儿童对食物组和营养品的消费之间的关联强度。平均而言，与少看电视的家庭相比，经常看电视的家庭的孩子每天从肉类摄取的能量多6%；从披萨、咸味零食和汽水获得的能量多5%；从水果、蔬菜和果汁摄入的能量比少看电视的家庭的孩子少近5%。在控制了社会经济因素和其他协变量的多元线性回归模型中，电视与儿童摄入食物组之间的关联在统计学上仍然显著。高电视家庭的儿童从碳水化合物中获得的总能量较少，而咖啡因的摄入量是低电视家庭儿童的两倍。当用多元线性回归模型检验这些关系时，电视和儿童咖啡因的摄入量之间仍然存在显著的关联。与看电视和吃饭是分开活动的家庭的孩子们的饮食模式相比，来自看电视是日常饮食习惯的家庭的孩子的饮食模式可能包括更少的水果和蔬菜，而更多的披萨、零食和苏打水。
Objective. We examined relationships between the presence of television during meals and children's food consumption patterns to test whether children's overall food consumption patterns, including foods not normally advertised, vary systematically with the extent to which television is part of normal mealtime routines.Methods. Ninety-one parent-child pairs from suburbs adjacent to Washington, DC, recruited via advertisements and word of mouth, participated. Children were in the fourth, fifth, or sixth grades. Socioeconomic data and information on television use were collected during survey interviews. Three nonconsecutive 24-hour dietary recalls, conducted with each child, were used to construct nutrient and food intake outcome variables. Independent sample t tests were used to compare mean food and nutrient intakes of children from families in which the television was usually on during 2 or more meals (n = 41) to those of children from families in which the television was either never on or only on during one meal (n = 50). Multiple linear regression models, controlling for socioeconomic factors and other covariates, were used to test strength of associations between television and children's consumption of food groups and nutrients.Results. Children from families with high television use derived, on average, 6% more of their total daily energy intake from meats; 5% more from pizza, salty snacks, and soda; and nearly 5% less of their energy intake from fruits, vegetables, and juices than did children from families with low television use. Associations between television and children's consumption of food groups remained statistically significant in multiple linear regression models that controlled for socioeconomic factors and other covariates.Children from high television families derived less of their total energy from carbohydrate and consumed twice as much caffeine as children from low television families. There continued to be a significant association between television and children's consumption of caffeine when these relationships were tested in multiple linear regression models.Conclusion. The dietary patterns of children from families in which television viewing is a normal part of meal routines may include fewer fruits and vegetables and more pizzas, snack foods, and sodas than the dietary patterns of children from families in which television viewing and eating are separate activities.
