ABSTRACT
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 significantly 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 differences 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 index was the highest value following BMI, WHtR and ABSI. CONCLUSIONS: Korean healthy subjects showed a correlation between IOP and anthropometric obesity indices regardless of gender, and the obesity index had the highest correlation.
