Correlation analysis of ocular biometric parameters and body mass index with myopia in children aged 6-11 years
Objective To investigate the correlation of degree of myopia with ocular biometric parameters and body mass index(BMI)in children aged 6-11 years.Methods A total of 215 myopic children aged 6-11 years were selected.The height(H),weight(W),and ocular biometric parameters such as axial length(AL),corneal radius(CR),anterior chamber depth(ACD),corneal white-to-white(WTW),pupil-diluted spherical equivalent(SE),and intraocular pressure(IOP)were measured.BMI and AL/CR were calculated,the results were sorted.The SE,ocular biology,H,W,and BMI of different genders of children were compared to analyze the correlation of SE with ocular biometric parameters,and the correlation of ocular biological parameters with the H,W,BMI,and age.Results There was no statistical significance in BMI,SE,W,AL/CR between men and women(P＞0.05).However,men had AL of(24.58±0.86)mm,ACD of(3.67±0.21)mm,WTW of(12.28±0.41)μm,which were higher than(24.28±0.84)mm,(3.60±0.19)mm,(12.11±0.38)μm in women;men had lower H of(1.42±0.11)m than(1.45±0.10)m in women;the difference was statistically significant(P＜0.05).Pearson correlation analysis showed that SE was negatively correlated with AL,AL/CR,ACD and IOP(r=-0.541,-0.740,-0.135,-0.118;P＜0.05),SE had no correlation with CR and WTW(r=0.042,-0.033;P＞0.05).Pearson correlation analysis showed that SE was negatively correlated with H,W,BMI and age(r=-0.055,-0.142,-0.168,-0.052;P＜0.05).WTW was negatively correlated with H(r=-0.066,P＜0.05),but had no correlation with W,BMI and age(P＞0.05).ACD and IOP were not correlated with H(P＞0.05),but were positively correlated with W,BMI and age(P＜0.05).AL and AL/CR were positively correlated with H,W,BMI and age(P＜0.05).CR had no correlation with H and age(P＞0.05),but was positively correlated with W and BMI(P＜0.05).Conclusion The myopia of school-age children has negative correlation with ocular growth and body growth.
