To analyze the influence of the eye biological parameters, height, and weight on the school-age children's refractive status. 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. 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 (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 ( 0.01). In the older children, the correlation between the SE and AL, AL/CR was stronger. Linear regression analysis showed SE= 26.55-9.11·AL/CR and 23.0-1.02·AL. 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 an older age, the correlation was more significant between the SE and AL, AL/CR. .
分析眼生物参数、身高和体重对学龄儿童屈光状态的影响。横断面研究。2012年6月至2013年6月期间，从温州8所学校选取了1656名7至14岁的儿童（1656只眼）。测量每个儿童的身高和体重，并计算体重指数（BMI）。使用IOLMaster（德国卡尔蔡司公司，版本5.0）测量眼生物参数，包括眼轴长度（AL）、角膜曲率（C = 1/CR）、前房深度（ACD）和白对白（WTW），并计算AL/CR。通过快速散瞳验光测量屈光，并计算等效球镜度（SE）。分析仅纳入右眼。使用SPSS16.0分析数据。评估等效球镜度、眼生物参数、身高、体重和BMI之间的相关性。对SE、AL和AL/CR进行线性回归分析。7至14岁学龄儿童近视的平均患病率为50.2%，男孩为48.4%，女孩为51.7%。平均SE为（-1.07±1.74）D。在调整年龄、性别、城乡因素后，SE与AL、AL/CR、ACD、身高和体重之间存在关联。相关系数分别为-0.663、-0.730、-0.416、-0.365和-0.281（P<0.05）。SE与WTW、角膜曲率和BMI之间无显著相关性。对于不同的屈光状态，远视、中度近视或高度近视儿童的SE与AL、AL/CR之间的相关性比正视或轻度近视儿童更强（P<0.01）。年龄较大的儿童中，SE与AL、AL/CR之间的相关性更强。线性回归分析显示SE = 26.55 - 9.11·AL/CR和23.0 - 1.02·AL。学龄儿童的SE与AL、AL/CR、ACD、身高和体重之间存在关联。在远视、中度近视、高度近视儿童或年龄较大的儿童中，SE与AL、AL/CR之间的相关性更显著。
