为探讨我国八十年代医科大学生热能需要量,选择宁夏医学院三、四年级男女生为对象,采用一日活动记录法及膳食称重法计算其每日热能消耗量与热能摄入量。结果发现男生摄入量与消耗量基本平衡,介于我国成年男子中、轻体力劳动供能标准2,600～3,000千卡之间,符合我国营养学界公认看法。女生耗能略低于成年女子轻体力劳动供能标准2,400千卡,而摄入热能明显低于一日活动耗能。身高体重测量结果,女生体重均值属正常范围偏低。女生热能摄入不足的主要原因是主食摄入过少;分析一日活动内容,女生体育活动时间明显少于男生,这也是其热能消耗较低的重要原因,若每日能有30min以上体育活动,将有效地提高热能消耗与促进热能摄入,增进健康。
In order to explore the thermal energy requirements of medical college students in the 1980s, we selected boys and girls in grade three and four in Ningxia Medical College as subjects, and calculated the daily caloric consumption and caloric intake using the daily activity recording method and dietary weighing method. The results showed that boys intake and consumption of basic balance, ranging from adult men in China, light physical labor and energy supply standards 2,600 ~ 3,000 kcal, in line with our recognized view of nutrition scholars. The energy consumption of girls was slightly lower than that of adult women with 2,400 kcal light physical labor, while the intake of heat was significantly lower than that of the first day. Height and weight measurements, the average weight of girls is a normal range of low. The main reason for the lack of energy intake for girls is that the intake of staple foods is too small. Analyzing the activities on the 1st day, the time for girls’ sports activities is significantly less than that for boys, which is also an important reason for their low energy consumption. If there is more than 30 minutes of daily physical activity , Will effectively improve heat consumption and promote energy intake, improve health.
