背景以前的研究表明，零食是导致美国儿童卡路里摄入量增加的原因，而且近十年来，美国饮食中零食的能量密度有所增加。目的研究1977至2014年间美国儿童零食能量密度和食物来源的短期和长期趋势，并检查不同社会人口群体之间的趋势是否不同。方法我们使用了1977至2014年间对49,952名2-18岁美国儿童进行的8项具有全国代表性的食物摄入量调查数据。结果1977-2014年间，在所有的社会人口学群体中，来自零食的人均能量摄入量显著增加(P
BackgroundPrevious studies have indicated that snacking is contributing to increased calorie intake of American children and that the energy density of snacks in US diets has increased in recent decades.ObjectiveExamine short-term and long-term trends in the energy density and food sources of snacks for US children from 1977 to 2014, and examine whether trends differ between socio-demographic groups.MethodsWe used data collected from eight nationally representative surveys of food intake in 49,952 US children age 2-18years, between 1977 and 2014. Overall patterns of snacking, trends in energy intake from snacking, trends in food and beverage sources and energy density of snacks across race-ethnic, age, gender, education and income groups were examined.ResultsIn all socio-demographic groups, there was a significant increase in per capita energy intake deriving from snacks from 1977 to 2014 (P
