目的：探讨大学生VitC营养水平与骨密度及骨矿物含量的关系。方法：随机选取105名大学生，口服500mgVitC后，收集4h尿液，测定尿中还原型VitC、尿钙、尿氟和尿肌酐含量，用BH－6012单光子骨密度仪测定左臂前1／3处桡骨和尺骨骨密度和骨矿物含量。用t检验和相关作统计分析。结果：VitC营养水平正常与充足的青年骨密度、骨矿物含量显著增高，而尿钙显著减少（＜0．01）。当VitC缺乏时，尿VitC与尿氟有显著性的负相关（P＜0．01）。结论：大学生VitC营养水平可能影响骨密度和骨矿物含量。
Objective: To investigate the relationship between VitC nutrition level and bone mineral density in college students. Methods: 105 college students were selected randomly and 500 mg VitC were taken orally. The urine samples were collected for 4 hours. The contents of urinary reduced VitC, urinary calcium, urinary fluoride and urinary creatinine were measured. The top 1/3 of the left arm was measured by BH-6012 single- Department of radius and ulna bone mineral density and bone mineral content. T test and related statistical analysis. Results: VitC nutrition level was normal and adequate young bone mineral density, bone mineral content was significantly increased, while urinary calcium was significantly reduced (<0.01). When VitC was deficient, there was a significant negative correlation between urine VitC and urinary fluoride (P <0.01). Conclusion: VitC nutrition level of college students may affect bone mineral density and bone mineral content.
