目的了解上海某高校偏瘦学生饮食习惯和营养状况,找出可能导致体格偏瘦的原因,并针对出现的问题进行合理的膳食干预。方法采用24 h膳食记录及称重法,连续5 d调查上海某高校30名BMI值在18.5以下大学生的膳食结构特点以及家庭状况,分析总结出可能导致消瘦的原因。结果我校学生体质偏瘦的成因不是单一的,主要原因可能是近一半的同学有不同程度的胃部不适,以致影响食物量的摄入和消化。其次是有一半同学存在不同程度的挑食现象,导致营养物质的摄入量不足以及摄入的营养素不均衡,这也可能和患有不同程度的胃部不适相关,影响食欲。结论男女生每日摄入的总能量分别为:7 917 kJ、7 114 kJ,这与DRIs推荐值10 032 kJ、8 778 kJ:有一定差距,因此需要进行针对性的膳食干预。

Conclusions The total energy intake of boys and girls per day is 7 917 kJ and 7 114 kJ, respectively, which is different from the recommended value of DRIs of 10 032 kJ and 8 778 kJ: therefore, targeted dietary intervention is needed.
