背景资料。本研究的目的是确定青少年饮食中按食物位置和食物类型摄入总能量的总体趋势。这项研究使用了1977年至1978年全国食物消费调查以及1989-1991年和1994-1996年连续的个人食物摄入量调查中具有全国代表性的16810人的样本，年龄在12-29岁之间。在每个调查年度，计算了12-18岁的青少年和19-29岁的年轻人从膳食和零食中摄取的总能量的百分比。分别计算两个年龄组按地点和特定食物组摄入的能量百分比。青少年和年轻人在家中摄入的能量较少，而在餐馆和快餐店摄入的能量较多。这主要见于青少年在零食场合摄入的卡路里，以及年龄较大的人群中的膳食和零食。在这两个年龄段中，披萨、芝士汉堡和咸味零食的消费量显著增加，而甜点和某些牛奶和肉类产品的消费量则有所下降。为了改善青少年和年轻人的饮食，家庭以外的健康食品选择需要像过去20年来越来越受欢迎的食品一样容易获得。(C)2002年美国健康基金会和爱思唯尔科学公司(美国)。
Background. The aim of this study was to determine overall trends of total energy intake by food location and food type in diets of adolescents and young adults.Methods. This study used a nationally representative sample of 16,810 individuals, ages 12-29 from the 1977 to 1978 Nationwide Food Consumption Survey and the 1989-1991 and 1994-1996 Continuing Surveys of Food Intake by Individuals. For each survey year, the percentage of total energy intake from meals and snacks was calculated for adolescents ages 12-18 and young adults ages 19-29. The percentage of energy intake by location and for specific food group was computed for both age groups, separately.Results. Both adolescents and young adults are obtaining less of their energy intake at home and more at restaurants and fast food places. This is predominantly seen among calories from snacking occasions for adolescents and both meals and snacks among the older age group. Significant increases in consumption of pizza, cheeseburgers, and salty snacks and decreases in consumption of desserts and certain milk and meat products by both age groups are shown.Conclusions. To improve the diets of adolescents and young adults, healthy food choices outside the home need to be as readily available as the foods which have increased in popularity over the past 20 years.
