Analysis on nutritional status of freshmen in 3 colleges of Liuzhou City in Guangxi Province from 2010-2014

目的了解广西柳州市大学新生营养状况,为改善大学生营养状况提供依据。方法以《国家学生体质健康标准》作为评价标准,对柳州市2010—2014年42 486名新生身高体重资料进行营养评价。结果 42 486名新生中营养不良率为17.43%,超重率和肥胖率分别为3.06%、7.39%;肥胖率男生(9.95%)明显高于女生(2.64%),差异有统计学意义(χ2=755.44,P<0.01);城市学生超重率(3.75%)高于乡村学生(2.57%),差异有统计学意义(χ2=45.5,P<0.01);城市学生肥胖率(10.71%)高于乡村学生(4.86%),差异有统计学意义(χ2=520.83,P<0.01)。结论柳州市大学新生营养状况不容乐观,营养不良未得到改善的同时肥胖率上升,新生营养不良与超重肥胖风险并存,应加强学校营养工作,增加学生体育锻炼,切实改善学生的营养状况。

[Objective] To understand the nutritional status of freshmen in Liuzhou City in Guangxi Province, provide the basis for improving nutritional status of college students.[ Methods ] According to the data of height and weight, the nutritional status of 42 486 freshmen in Liuzhou City from 2010-2014 were evaluated by National Student Physical Health Standard.

The obesity rate of boys （9.95%） was higher than that of girls （2.64%）, and the difference was statistically significant （X2=755.44,/〉〈0.01）. The overweight rate of urban students （3.75%） was higher than that of rural students（2.57%）, and the difference was statistically significant （X2=245.5, P〈0.01）. The obesity rate of urban students （10.71%） was higher than that of rural students （4.86%）, and the difference was statistically significant （X2=520.83, P〈0.01）. [ Conclusion] The nutritional status of freshmen in Liuzhou City is not optimistic. The malnutrition rate has not been improved while the obesity rate is increasing, and the risks of malnutrition and obesity are coexisted.
