Relationships between Anthropometric Measurements and Intraocular Pressure: The Korea National Health and Nutrition Examination Survey

Abstract Purpose To evaluate the relationship between intraocular pressure (IOP) and various anthropometric measures. Design A population-based cross-sectional study. Methods Patients: A total of 5,008 participants, 2,080 men and 2,928 women, aged ≥19 years were included from the Korea National Health and Nutrition Examination Survey V database, focusing on the years 2010 and 2011. We selected IOP in the right eye of a normal healthy population as the outcome variable of our study. We analyzed the relationship between IOP and anthropometric parameters using dual-energy X-ray absorptiometry by sex. Lean body mass was calculated as total body mass minus fat mass. We used general linear models and logistic regression analysis to evaluate risk factors of high IOP. Main outcome Measure: Correlation between anthropometric data and IOP. Results In multivariate general linear models, greater body mass index (BMI) and waist circumference were correlated with higher IOP for both men (BMI: β=0.053, P=0.026, waist circumference: β=0.016, P=0.067) and women (BMI: β=0.074, P
