【摘要】：目的通过对空军青少年航空学校学员视力和屈光状况及其影响因素的分析,确定影响该人群视力变化的关键因素,为开展和保证视力监控的有效性提供科学依据。方法对比403名青少年航空学校学员定选及入校后3个月远视力变化及现阶段的屈光情况,并对可能影响学员视力变化的因素进行问卷调查,分别采用Wilcoxon符号秩检验和Logistic回归分析视力变化程度及主要影响因素。结果入校仅3个月,学员远视力变化即存在显著差异(P0.05),低常率达到28.79%,9.68%的学员视力下降至0.8。散瞳后屈光检查结果提示27.05%的学员屈光不良。现阶段阅读姿势和饮食偏好是造成学员们短期视力下降的主要危险因素。结论定期对学员的远视力及屈光度进行监测对于优选飞行苗子、提高成飞率、了解和制定视力保护措施具有重要意义。视力保护需要常抓不懈,科学有效的监管和学员主观努力相结合,才能真见成效。只有持之以恒地进行视力保护,充分发挥学员自身的主观能动性才能真正起到保护视力的作用。
[Abstract]:Objective to analyze the visual acuity, refractive index and its influencing factors of air force youth aviation school students, and to find out the key factors that affect the visual acuity change of this population, and to provide scientific basis for carrying out and ensuring the effectiveness of visual surveillance.Methods A total of 403 students from aviation school were enrolled in this study. The changes of distant vision and refractive index were compared 3 months after admission, and the factors that might influence the changes of vision were investigated by questionnaire.Wilcoxon sign rank test and Logistic regression analysis were used to analyze the degree of visual acuity change and the main influencing factors.Results only 3 months after admission, there was a significant difference in far visual acuity of students (P 0.05), and the visual acuity of students with low normal rate of 28.79% and 9.68% decreased to 0.8%.The results of refractive examination after mydriasis showed that 27.05% of the students had ametropia.At present, reading posture and eating preference are the main risk factors for students' short-term vision decline.Conclusion it is of great significance to monitor the distant vision and diopter of cadets regularly in order to select the flying seedling, improve the flying rate, understand and formulate the measures of visual protection.The vision protection needs unremitting, scientific and effective supervision and students subjective efforts to achieve real results.Only by persisting in visual protection and giving full play to students' subjective initiative can they really play a role in protecting eyesight.
