摘要
目的了解托幼机构学龄前儿童视力低于正常(低常)的发生情况,分析遗传、家庭环境、生活习惯等因素对学龄前儿童视力低常的影响,为采取有效的干预措施提供依据。方法整群抽取闵行区6家托幼机构13个分点为基地,选取小班、中大班级3-6岁儿童2 054名。采用全国统一的对数视力表检查视力并对家长进行问卷调查。运用SPSS16.0软件进行描述性分析、χ^2检验、多因素Logistic回归分析等统计分析方法。结果学龄前儿童视力筛查低常696人,低常检出率为33.9%,其中男童检出率为32.8%(342/1 043),女童检出率为35.0%(354/1 011)。学龄前男童、女童视力筛查低常检出率无统计学差异(χ^2=1.134,P〉0.05)。随着年龄增长学龄前儿童视力低常的检出率逐渐升高,且在不同年龄组差异具有统计学意义(χ^2=225.940,P〈0.01)。儿童平时有眯眼习惯、儿童平时有视近习惯是学龄前儿童视力低常检出的危险因素。结论应重视学龄前儿童视力保护工作,采取综合措施早期干预儿童视力低常的发生。
