【摘要】：目的：探索长期进行钢琴弹奏练习的学龄儿童眼轴长度变化及其影响因素。设计：横断面调查研究。研究对象：1724名上海市6-11岁汉族儿童。有长期钢琴弹奏练习的经历(最短1年,最长8年)并且参加了2010年上海市钢琴考级考试的901名(52.26%)琴童,对照组为在参加本研究之前没有任何钢琴弹奏练习经历的823名(47.74%)普通儿童。方法：儿童相关信息通过调查问卷形式获得,包括年龄、性别、身高、父母近视人数、每天近距离工作时间、每天户外活动时间,以及琴童钢琴弹奏练习相关的因素。用IOL-master进行眼轴长度的测量。应用t检验方法比较不同组别的眼轴长度；多重线性回归模型分析反应变量与各个解释变量之间的关系,以眼轴长度作为因变量,钢琴弹奏练习因素、非钢琴弹奏练习因素作为自变量,评价这些因素对眼轴长度的影响作用。结果：所有儿童的眼轴长度呈现正态分布,平均眼轴长度为23.54±0.99mm(20.51-26.86mm),男童长于女童(23.84±0.99mm vs.23.35±0.95mm,P0.001)；多重线性回归模型显示,眼轴长度随年龄增长而增长(回归系数b=0.21,P0.001),男童比女童长0.48mm(P0.001),身高越高眼轴越长(1cm,b=0.01,P0.001),父母近视人数多的儿童眼轴长,儿童父母均近视、一人近视比没有父母近视眼轴分别长0.44mm、0.23mm (P0.001),户外活动时间短的儿童眼轴长度长,每天户外活动时间小于半小时的儿童比超过1.5小时的儿童眼轴长0.16mm(P0.05),有长期钢琴弹奏练习经历的儿童比没有钢琴弹奏练习经历儿童长0.21mm(p0.001),每天读书学习时间、是否用电脑对眼轴长度的影响未显示出有统计学意义(P0.05)。单独对琴童分析,性别、年龄、身高、父母近视人数、每天户外活动时间仍然显示出对眼轴长度的影响作用；匹配了年龄、性别、身高、父母近视人数、每天户外活动时间、每天看电视时间后,每天进行钢琴弹奏练习儿童比间断进行钢琴弹奏练习儿童眼轴长0.14mm(P0.05),参加钢琴考级级别越高的儿童眼轴越长(b=0.11,p0.001),开始学琴年龄、每天钢琴弹奏练习总时间、钢琴弹奏练习间歇时间对眼轴长度的影响未显示出有统计学意义(P0.05)。结论：本研究证明了在上海市6-11岁的汉族儿童中,年龄、性别、父母近视史、身高对眼轴长度的影响最大。父母近视人数多者眼轴长,身高越高眼轴越长,户外活动时间短者眼轴长；在上述因素均匹配的情况下,琴童比非琴童眼轴长,进行钢琴弹奏练习频次高(每天练习)的琴童眼轴长,钢琴考级级别越高的琴童眼轴越长。
[Abstract]:Objective: to explore the changes of eye axis length and its influencing factors in school age children who have been playing piano for a long time. Design: cross-sectional investigation. Participants: a total of 1724 Han children aged 6-11 years in Shanghai. Have a long experience of playing piano (at least one year, up to eight years) and 901 students who took part in the 2010 Shanghai Piano examination. The control group consisted of 823 children who had not experienced any piano practice before taking part in this study. Methods: information about children was obtained by questionnaire, including age, sex, height, myopia of parents, close working hours every day, outdoor activities every day, and the factors related to piano playing. The length of eye axis was measured by IOL-master. T test method was used to compare the eye axis length of different groups, the multiple linear regression model was used to analyze the relationship between the response variables and the various explanatory variables, and the eye axis length was used as the dependent variable. The factors of non-piano playing were used as independent variables to evaluate the effect of these factors on the length of eye axis. Results: the length of eye axis in all children was normal distribution, the average length of eye axis was 23.54 卤0.99mm ~ 20.51-26.86mm, the length of eye axis of boys was 23.84 卤0.99mm vs.23.35 卤0.95mm (P 0.001) than that of girls, and the multiple linear regression model showed that, The length of eye axis increased with age (regression coefficient BX 0.21% P0.001g, boys 0.48mm) longer than girls (P 0.001), the taller the height of the eyes, the longer the axial axis was, the longer the axial length was, the more myopia the children were, the more their parents were myopia, the higher the height of the eye axis was, the longer the axial length of the eye axis was. One person's myopia was 0.44mm / 0.23mm / (P 0.001) longer than that without parent's myopia, and the length of eye axis was longer in children with shorter outdoor activities. Children with less than half an hour of outdoor activities a day had an eye axis of 0.16mm / kg longer than those with a duration of more than 1.5 hours, and children with a long experience of playing the piano were 0.21mm / p 0.001 longer than those who had no experience of playing the piano, and they spent a lot of time reading and studying every day. The effect of computer on axial length was not statistically significant (P 0.05). Sex, age, height, number of myopia parents, outdoor activity time per day still showed an effect on the length of eye axis, matched age, sex, height, number of parents myopia, daily outdoor activity time, After watching TV every day, children practiced piano playing every day, and the children had 0.14 mm long eye axis of children than those with intermittent piano playing. The higher the grade of piano examination, the longer the axial length of children's eyes was 0.11p 0.001. The children began to learn piano, and the total time of daily piano playing practice was total. The effect of the interval time of piano playing on the length of eye axis was not statistically significant (P 0.05). Conclusion: this study demonstrated that age, sex, parents' myopia and height had the greatest influence on the length of eye axis in 6-11 year old Han children in Shanghai. The more myopic parents were, the longer the axial axis was, the longer the height, the longer the length of the eye axis, and the longer the axial length of the eye axis of the children with shorter outdoor activity time. In the case of all the above factors matched, the axial length of the children was longer than that of the non-children. Children with high frequency of piano playing (daily practice) have long eyelids, and children with higher grades of piano exams have longer axes.
