Cross-Sectional Study between Anthropometric Obesity Indices and Intraocular Pressure

3 , Yangsan, Korea Purpose: To investigate the cross sectional study association of intraocular pressure (IOP) with anthropometric obesity indices. Methods: We classified study subjects into three groups--normal, overweight and obesity, and investigated the correlation of IOP with age, gender and anthropometric obesity indices such as obesity Index, body mass index (BMI), a body shape index (ABSI) and waist to height ratio (WHtR) on healthy subjects. Results: Of a total of 63,385 participants, 30,288 were male and 33,097 were female. Mean IOP was 15.13 ± 3.24 mm Hg for men and 14.44 ± 3.02 mm Hg for women. The obesity index and BMI in the normal, overweight and obesity groups were sig- nificantly different in both men and women (p < 0.05). Mean IOP increased to a higher degree in the obesity group. In the normal, overweight and obesity group divided by ABSI, there were no significant differences in both men (p = 0.66) and women (p = 0.28). Between the normal and overweight group and the normal and obesity group divided by WHtR, there were significant dif- ferences in men (p < 0.05) and women (p < 0.05). Multiple linear regression analysis showed the significant relationship between obesity index, BMI, ABSI, WHtR and IOP in men and women. Receiver operating characteristic curve showed that the obesity in- dex was the highest value following BMI, WHtR and ABSI. Conclusions: Korean healthy subjects showed a correlation between IOP and anthropometric obesity indices regardless of gen- der, and the obesity index had the highest correlation.
