本文报告了140名健康大学生和50名加服足量维生素 A 的同质人群暗适应测定结果,其均数±标准差分别为33.04±1.57秒和24.7±5.6秒,表明暗适应的正常值取两组单侧80%的上限值分别为不同营养水平的评价标准较适宜,提出了健康大学生暗适应时间小于30秒为 VA 营养充裕,30～49秒为 VA 营养正常水平,大于或等于50秒为 VA 营养缺乏的评价标准.
In this paper, we report the results of dark adaptation of 140 healthy college students and 50 homozygous groups with adequate vitamin A, with mean ± standard deviation of 33.04 ± 1.57 seconds and 24.7 ± 5.6 seconds, respectively, indicating that the normal value of dark adaptation The upper limit of 80% on one side of the two groups is more appropriate for the evaluation criteria of different nutrition levels. It is suggested that the dark adaptation time of healthy college students is less than 30 seconds, which is VA nutrition adequacy, 30-49 seconds is VA normal nutrition level, greater than or equal to 50 Seconds VA assessment of nutritional deficiencies.
