目的了解医学生视力情况及用眼习惯,分析影响学生视力的主要因素。方法对某医学院校临床医学专业大一、大二学生随机抽取200名进行问卷调查。采用EpiData 3.1软件建立数据库,使用SPSS17.0软件进行统计分析,采用秩和检验和spearman秩相关进行统计学处理。结果在发放的200份问卷中,有效问卷183份,其中学生近视率为82.5%(轻度近视占33.9%;中度近视占40.4%,重度近视占8.2%)。父母视力情况不同的学生近视程度有差异(P<0.05),“平时学习时眼睛书本距离”、“平时看书写字姿势”、“是否经常躺着看书玩手机”、“平时学习中是否主动休息”与近视程度相关系数依次为-0.247、-0.150、-0.151和0.256,其相关性差异有统计学意义(P均<0.05)。结论正确的用眼姿势,良好的用眼习惯是近视预防和控制的最有效方式。
Objective To understand the visual acuity and habits of medical students and to analyze the main factors affecting the visual acuity of students. Methods A random sample of 200 freshmen and sophomores from a medical college were enrolled in the questionnaire. EpiData 3.1 software was used to establish the database, and SPSS17.0 software was used for statistical analysis. Rank sum test and spearman rank correlation were used for statistical analysis. Results Among the 200 questionnaires distributed, 183 were valid questionnaires, of which myopia was 82.5% (mild myopia 33.9%; moderate myopia 40.4%, severe myopia 8.2%). There were significant differences in the degree of myopia between parents with different visual acuity (P <0.05), “distance between eyes and eyes when learning”, “reading and writing position at ordinary times”, “ Whether to take the initiative to rest in normal learning ”and the correlation coefficient between myopia and -0.247, -0.150, -0.151 and 0.256 in turn, the correlation was statistically significant (P <0.05). Conclusion Correct use of eye posture, good eye habits is the most effective way to prevent and control myopia.
