Data from 1,392 children ages 1 to 10, who were participants in the U.S. Department of Agriculture 1987-88 Nationwide Food Consumption Survey, were examined to determine how their diets compared with current dietary recommendations and to identify those sociodemographic factors associated with the greatest risk for not meeting the recommendations. Vitamin A, vitamin E, vitamin C, calcium, iron, and zinc were the nutrients most often consumed below recommended levels. Percentage of calories from fat and saturated fat and mean sodium intakes were above recommended levels for the majority of the children. Of the total sample, 81 percent met guidelines for cholesterol intakes. Multiple correlation regression analysis was used to determine the effect of the following factors on the children's nutrient intakes: geographic region, degree of urbanization, race, household size and income, age, education, and employment status of the male and female head of household. Age and sex of the child were entered as control variables. Level of urbanization affected the most nutrient intake variables, followed by race. Living in a rural area and being black were significant predictors for higher intakes of total fat, saturated fat, cholesterol, and sodium. Mean annual household income had no significant effect on any of the diet quality measures. Many of the children in the sample, however, participated in Federal food and nutrition programs that provided additional resources for food.
对1392名年龄在1至10岁的儿童的数据进行了研究,这些儿童参与了美国农业部1987 - 1988年全国食品消费调查,目的是确定他们的饮食与当前饮食建议相比情况如何,并找出那些与未达到建议的最大风险相关的社会人口学因素。维生素A、维生素E、维生素C、钙、铁和锌是最常低于推荐水平摄入的营养素。对于大多数儿童来说,来自脂肪和饱和脂肪的热量百分比以及钠的平均摄入量高于推荐水平。在总样本中,81%的儿童符合胆固醇摄入指南。多元相关回归分析用于确定以下因素对儿童营养素摄入量的影响:地理区域、城市化程度、种族、家庭规模和收入、年龄、教育程度以及家庭男女户主的就业状况。儿童的年龄和性别作为控制变量录入。城市化程度对大多数营养素摄入变量影响最大,其次是种族。生活在农村地区和身为黑人是总脂肪、饱和脂肪、胆固醇和钠摄入量较高的显著预测因素。家庭年均收入对任何饮食质量指标均无显著影响。然而,样本中的许多儿童参与了联邦食品和营养项目,这些项目为食品提供了额外资源。
