To explore the risk factors for abnormal blinking in children and compare these between boys and girls.
Children attending the Children's Optometry Clinic between June 2019 and June 2020 were recruited for the study. The time they had spent viewing video displays (VDTt) over the past 6 months was recorded. Incomplete blinking (IB) and blinking rate were measured and all participants were allocated to groups based on their blink rate (<20 times/min = normal blinking group, NBG; ≥20 times/min = abnormal blinking group, ABG). Tear film (TF) stability was also evaluated. The corresponding statistical methods are used to analyze the data.
A total of 87 boys and 80 girls were enrolled in the study. No significant difference in age was found between the 2 groups. There was a significant difference in TF stability between the two groups (P<0.05). According to binary logistic analysis, VDTt and ocular protection index (OPI) are important risk factors for abnormal blinking, with cut-off values of 1.75 hours and 1.014 respectively in boys; and 1.25 hours and 1.770 respectively in girls. The average of lipid layer thickness was an important protective factor for children using VDT for long periods, with a cut-off value of 58.5 nm in boys and 53.5nm in girls.
Risk factors for abnormal blinking in both boys and girls include VDTt and OPI.
探讨儿童异常眨眼的危险因素，并比较男孩和女孩之间的差异。
本研究招募了 2019 年 6 月至 2020 年 6 月期间在儿童验光诊所就诊的儿童。记录他们过去 6 个月观看视频显示设备（VDTt）的时间。测量不完全眨眼（IB）和眨眼频率，并根据眨眼频率将所有参与者分配到以下组：<20 次/分钟=正常眨眼组（NBG）；≥20 次/分钟=异常眨眼组（ABG）。还评估了泪膜（TF）稳定性。使用相应的统计方法分析数据。
共有 87 名男孩和 80 名女孩入组研究。两组间年龄无显著差异。两组间 TF 稳定性存在显著差异（P<0.05）。根据二元逻辑分析，VDTt 和眼保护指数（OPI）是异常眨眼的重要危险因素，男孩的截断值分别为 1.75 小时和 1.014；女孩的截断值分别为 1.25 小时和 1.770。长时间使用 VDT 的儿童的平均脂质层厚度是重要的保护因素，男孩的截断值为 58.5nm，女孩的截断值为 53.5nm。
男孩和女孩异常眨眼的危险因素包括 VDTt 和 OPI。
