某坦克部队外训期间的膳食营养调查

目的:了解坦克部队官兵在野外驻训期间的膳食营养状况,为指导合理膳食提供参考依据。方法:膳食调查采用称重法,能量消耗采用生活观察法,体格检查指标包括体重和皮褶厚度。结果:每日人均禽肉、鱼虾、蔬菜等摄入水平未达到"军人食物定量"标准,而植物油摄入量则超过军标要求;VB1、VC、铁、锌、硒、碘等摄入量未达到"军人营养素供给量"标准要求;三大产能营养素供能比例不合理,脂肪摄入偏高,碳水化合物偏低;多数官兵野外驻训7 d后体重和皮褶厚度降低。结论:该部队在野外驻训期间膳食结构不够合理,部分营养素摄入量未达到军标要求,应调整膳食结构,改善官兵的营养状况。

Dietary Survey of Tank Crews during Field Training

Objective:To investigate the nutritional status of tank crews during field training, so as to provide basis for rational diet.Methods:Weighing method was used in dietary survey, life observation method was used to assay energy expenditure, and physical examination included body weight and skinfold thickness measurement.Results:The daily intake of poultry, fish and vegetables was less than the military standard, whereas vegetable oil intake was higher than the military standard; the daily supply of VB1,VC, Fe, Zn, Se and I did not meet the military standard; The energy supply ratio of three energetic nutrients was imbalanced, the ratio of fat was higher while carbohydrate was lower than military standard; weight and skinfold thickness of many soldiers were reduced after 7 d field training.Conclusion:The dietary structure is not rational, some nutrients supply can not meet the needs of soldiers. It is necessary to adjust dietary structure for improving the nutritional status of soldiers during field training.
