目的:探讨我军重度劳动部队推荐的维生素C摄入量。方法:选择南北方炮兵、装甲兵11个基层部队,共285人,采用膳食调查、体格检查、4 h尿负荷试验法评价维生素C营养状况。结果:各调查单位膳食维生素C摄入量为110.5~147.8 mg;4 h维生素C尿负荷试验结果表明,各调查单位维生素C营养状况处于正常状态人员占69.5%,处于不足状态的人员占30.5%;体格检查发现31人有维生素C缺乏症状。通过相关分析得出我军重度劳动部队膳食维生素C推荐摄入量至少不应低于140 mg。结论:我军重度劳动部队膳食维生素C推荐摄入量可为140 mg,今后应采用其他方法进一步研究维生素C推荐摄入量。
Objective: To investigate the recommended intake of vitamin C by our army’s heavy labor force. Methods: Eleven grassroots units of artillery and armored forces from south and north were selected. A total of 285 troops were employed to evaluate the nutritional status of vitamin C by dietary survey, physical examination and 4 h urine load test. Results: The intake of dietary vitamin C was 110.5-147.8 mg in each survey unit. The results of 4-h vitamin C urine load test showed that 69.5% of the vitamin C nutritional status of the surveyed units were in the normal state, 30.5% of the staff in the deficient state, ; Physical examination found that 31 people have vitamin C deficiency symptoms. Through the correlation analysis, it is concluded that the recommended intake of dietary vitamin C for the Severe Labor Forces in our army should not be less than 140 mg. Conclusion: The recommended intake of dietary vitamin C for the severe labor force in our army may be 140 mg. In the future, other methods should be adopted to further study the recommended intake of vitamin C.
