Energy intake, total volume (bulk) and the energy density (kcal/ml) of the diets of preschool children of middle and lower-middle economic groups from an urban area and of a rural low economic group were examined. The energy intake of children from the urban area was higher than that of the children from the rural area. The total solid intake in the three groups was not different. However, the energy density of the diets (kcal/ml) of the urban preschool children (1.17 kcal/ml or 4.74 kJ/ml) was significantly higher as compared to the energy density of the diets of rural children (0.74 kcal/ml or 2.94 kJ/ml). The urban children of higher income groups had a much higher intake of fat and milk than the rural poor children, which accounts for the differences in the energy densities of their diets. The results of this study suggest that one of the reasons for low energy intake of rural poor preschool children may be the low energy density of their diets.
对来自城市地区中低收入经济群体以及农村低经济群体的学龄前儿童饮食的能量摄入、总体积（容量）和能量密度（千卡/毫升）进行了研究。城市地区儿童的能量摄入量高于农村地区儿童。三组儿童的总固体摄入量没有差异。然而，城市学龄前儿童饮食的能量密度（千卡/毫升）（1.17千卡/毫升或4.74千焦/毫升）明显高于农村儿童饮食的能量密度（0.74千卡/毫升或2.94千焦/毫升）。高收入群体的城市儿童比农村贫困儿童摄入的脂肪和牛奶要多得多，这解释了他们饮食能量密度的差异。本研究结果表明，农村贫困学龄前儿童能量摄入低的原因之一可能是他们饮食的能量密度低。
