为观察学龄前儿童一日活动能量消耗和膳食摄入并验证营养学会推荐的能量供给量是否符合生长需要,最近我们一次调查发现生长发育与能量消耗、膳食摄入、一日生活管理有密切联系。 对象与方法 选择3～5岁集体儿童115名为膳食调查对象,并随机抽取男女各5名儿童测量能量消耗,由专人跟踪连续记录48小时各类活动与时问,按何氏法计算全日能量消耗;膳食调查采用秤重法,时问为二天,计算每天每人实际摄入能量。调查时间为春末。 结果与分析 每天儿童摄入能量为1153.39Kcal,其中蛋白质占总热能的16.6％,脂肪占30.4％,糖类占53％,总热能和三大营养素与供给量标准相 In order to observe the energy consumption and dietary intake of preschool children in one day and to verify whether the nutrition supply recommended by Nutrition Society meets the growth needs, we recently found that growth and development are closely related to energy consumption, dietary intake and daily life management . Subjects and Methods 115 children aged 3 to 5 years were selected as the dietary survey subjects and 5 boys and girls were randomly selected to measure the energy consumption. The activities were tracked continuously for 48 hours by specialists. The total energy Consumption; Dietary surveys using weighing method, when asked for two days, calculate the actual intake of energy per person per day. The investigation time is late spring. Results and Analysis Daily intake of energy for children was 1153.39Kcal, of which protein accounted for 16.6% of total calories, fat accounted for 30.4%, carbohydrate accounted for 53% of the total heat and the three nutrients and the supply of standard phase
