摘　　要： 目的了解大连市山区与平原地区学生的远视力状况,探讨地理环境与近视眼的关系。方法 2015年9~11月整群选取大连市普兰店区山区学校与平原学校学生合计3 884名按照学段分组。描述指标为近视比率、平均视力、平均视角等。结果调查3 884人(7 768只眼),山区2个乡镇初中生不一致,平均视力分别为4.81、4.76(P<0.05);平原2个乡镇初中生也不一致,平均视力分别为4.80、4.76(P<0.01)。初中阶段,增长最快的是山区的、平原的乡镇各1个,平均视角的环比分别为94.53%、90.56%,而山区的另一个乡镇增长最慢,环比为35.83%。结论近视眼与地理环境的关联不明显,反映出其他因素的重要性。 Objective To understand the distant vision among students of schools in mountain area or in plain area,so as to explore the relation between geographical condition and myopia. Methods During September-November 2015,3 884 students were selected from schools in mountain area and plain area of Pulandian district,Dalian city,and the ratio of myopia,the mean of vision and the mean visual angle were calculated. Results A total of 3 884students（7 786 eyes）were surveyed,there was significant difference in the mean vision of students from 2junior high schools in mountain towns,at4.81 and 4.76respectively（P〈 0.05）.There was also significant difference in the mean vision of students from 2junior high schools in plain towns,at 4.80 and 4.76respectively（P〈 0.01）.In the junior high school stage,the fastest growth of mean vision angle was from one mountain junior high school and one plain junior high school,the link relative ratio of mean vision angle was 94.53% and 90.56% respectively;and the slowest growth of mean vision angle was from one mountain junior high school,the link relative ratio of mean vision angle was 35.83%. Conclusion The correlation between myopia and geographical condition is not obvious,reflecting the importance of other factors.
