BACKGROUND/AIM: To quantify the impact of baseline presenting visual acuity (VA), refractive error and spectacles wear on subsequent academic performance among Chinese middle school children.
A prospective, longitudinal, school-based study on grade 7 Chinese children (age, mean±SD, 12.7±0.5 years, range=11.1-15.9) at four randomly selected middle schools in Anyang, China. Comprehensive eye examinations including cycloplegic autorefraction were performed at baseline, and information on demographic characteristics, known risk factors for myopia and spectacle wear was collected. Academic test scores for all subjects in the curriculum were obtained from the local Bureau of Education. Main outcome measure was total test scores for five subjects at the end of grade 9, adjusted for total scored at the beginning of grade 7.
Among 2363 eligible children, 73.1% (1728/2363) had seventh grade test scores available. 93.9% (1623/1728) completed eye examinations, and 98.5% (1599/1623) of these had ninth grade test scores. Adjusting only for baseline test score, the following were significantly associated with higher ninth grade scores: younger age, male sex, less time outdoors, better baseline presenting VA, higher parental education and income and parental myopia, but refractive error and spectacle wear were not. In the full multivariate model, baseline test score (p<0.001), presenting VA (p<0.01), age (p<0.001), quality of life (p<0.05) and parental education (p<0.001) and myopia (either: p<0.05; both: p<0.05) remained significantly associated with better ninth grade scores.
In this longitudinal study, better presenting VA, but not cycloplegic refractive error or spectacle wear, was significantly associated with subsequent academic performance.
背景/目的：量化中国中学生基线时的视力（VA）、屈光不正和戴镜情况对其后续学业成绩的影响。
在中国安阳市的四所随机选定的中学中，对七年级（年龄，平均值±标准差，12.7±0.5 岁，范围 11.1-15.9 岁）的中国儿童进行前瞻性、纵向、基于学校的研究。在基线时进行全面的眼科检查，包括睫状肌麻痹自动验光，并收集有关人口统计学特征、近视的已知危险因素和戴镜情况的信息。从当地教育局获得所有课程的学科考试成绩。主要观察指标是九年级末的五门学科的总考试成绩，根据七年级初的总得分进行调整。
在 2363 名合格儿童中，有 73.1%（1728/2363）有七年级的考试成绩。有 93.9%（1623/1728）完成了眼部检查，其中 98.5%（1599/1623）有九年级的考试成绩。仅调整基线测试成绩，以下因素与较高的九年级成绩显著相关：年龄较小、男性、户外活动时间较少、较好的基线视力、较高的父母教育程度和收入以及父母近视，但屈光不正和戴镜情况无关。在全变量模型中，基线测试成绩（p<0.001）、表现视力（p<0.01）、年龄（p<0.001）、生活质量（p<0.05）和父母教育（p<0.001）和近视（单侧：p<0.05；双侧：p<0.05）与更好的九年级成绩仍显著相关。
在这项纵向研究中，更好的表现视力，但不是睫状肌麻痹的屈光不正或戴镜情况，与随后的学业成绩显著相关。
