摘　　要：目的 分析眼生物学参数、身高、体重等因素对学龄期儿童屈光状态的影响.方法 收集2012年6月至2013年6月温州地区8所小学7～14岁儿童为研究对象,共计1 656例（1 656只眼）.测量每位儿童身高、体重,采用IOLMaster测量眼轴长度（AL）、角膜屈光度、前房深度、白对白,计算眼轴/角膜曲率半径比值（AL/CR）、体重指数（BMI）.快速散瞳后检影验光测得屈光度数,并将其换算为等效球镜度数（SE）.对SE与眼各生物学参数、身高、体重、BMI进行相关性分析及回归分析.结果 7～14岁儿童平均近视比例为50.2％,男童48.4％,女童51.7％.平均SE为（-1.07± 1.74）D.校正年龄、性别、城乡等因素后,SE与AL、AL/CR、前房深度、身高、体重存在相关性,相关系数分别为-0.663、-0.730、-0.416、-0.365、-0.281（P＜0.05）,SE与白对白、角膜屈光度、BMI无关联性.按不同屈光状态分组,远视和中高度近视儿童的等效球镜度与AL、AUCR相关性较正视和轻度近视儿童强,差异有统计学意义（P＜0.01）;按不同年龄分组,年龄越大的儿童的等效球镜度与AL、AL/CR相关性越强.SE与AL、AL/CR直线回归分别为：SE=26.55-9.11· AL/CR,SE=23.0-1.02×AL.结论 7～14岁学龄期儿童的屈光状态与AL、AL/CR、前房深度、身高、体重存在相关性.其中远视、中高度近视、年龄越大儿童的SE与AL、AL/CR的相关性更强.Objective To analyze the influence of the eye biological parameters,height,and weight on the school-age children＆#39;s refractive status.Methods Cross-sectional study.A total of 1 656 children （1 656 eyes）,aged from 7 to 14 years,were selected from 8 schools in Wenzhou during June 2012 and June 2013.The height and weight of each child were measured,and the body mass index （BMI） was calculated.The eye biological parameters,including axial length （AL）,corneal power （C=1/CR）,anterior chamber depth （ACD）,and white to white （WTW）,were measured by IOLMaster （version 5.0,Carl Zeiss,Germany）,and the AL/CR was calculated.Refraction was measured by fast cycloplegic retinoscopy,and the spherical equivalent （SE） was calculated.Only right eyes were included in the analysis.SPSS16.0 was used to analyze the data.The correlations of the equivalent spherical power,the eye biological parameters,height,weight,and BMI were evaluated.Linear regression analysis was used for the SE,AL,and AL/CR.Results The prevalence of myopia in 7-to 14-year-old school-age children was 50.2% on the average,48.4% in boys,and 51.7% in girls.The average SE was （-1.07± 1.74）D.With adjustment of the age,gender,urban and rural areas,there was an association between the SE and AL,AL/CR,ACD,height and weight.The correlation coefficient was-0.663,-0.730,-0.416,-0.365,and-0.281,respectively （P〈0.05）.There was no significant correlation between the SE and WTW,corneal power and BMI.Regarding the different refractive statuses,there was a stronger correlation between the SE and AL,AL/CR in children with hyperopia,moderate myopia or high myopia than those with emmetropia or mild myopia （P〈 0.01）.In the older children,the correlation between the SE and AL,AL/CR was stronger.Linear regression analysis showed SE=26.55-9.1 1 ·AL/CR and 23.0-1.02·AL.Conclusions There was an association between the SE and AL,AL/CR,ACD,height and weight in school-age children.In children with hyperopia,moderate myopia,high myopia or at a
