Anthropometric Measures and Their Relationship to Steep Cornea in the United States Population.

PURPOSE:The aim of this study was to determine the relationship between anthropometric measures and steep cornea. METHODS:Participants from the 1999 to 2008 US National Health and Nutrition Examination Survey visual examination were included (20,165 subjects). Cases had a mean dioptric power, averaged across the meridians, ≥ 48.0 diopters (n = 171). Separate multivariable models assessed body mass index, height, and weight in relation to steep cornea. Analyses included both overall and sex-stratified populations. RESULTS:A relationship between BMI and steep cornea in the overall population was not detected ( P for trend = 0.78). There was a strong inverse relationship between height (adjusted for weight) and steep cornea in the overall population ( P for trend <0.0001) and in women ( P for trend <0.0001). For every 1-inch increase in height, there was a 16% reduced odds of steep cornea in the overall population (OR, 0.84; 95% CI: 0.77-0.92). A relationship between weight and steep cornea was not detected in the overall population (P for trend = 0.79). CONCLUSIONS:Greater height was associated with a lower risk of steep cornea.
