Association between body mass index and myopia in the United States population in the National Health and Nutrition Examination Surveys 1999 to 2008: a cross-sectional study.

ABSTRACT:

Background

This study investigated the association between body mass index (BMI) and myopia in the United States.

Methods

This cross-sectional study included 8,000 participants from the 1999 to 2008 National Health and Nutrition Examination Survey (NHANES). BMI was classified into four groups: < 18.5, 18.5 - 24.9, 25-29.9, and > 29.9. Three diagnostic thresholds were used for myopia A\B\C: spherical equivalent ≤ -0.5\-0.75\-1 diopters in the right eye. Multivariate logistic regression analysis and smooth curve fitting were performed to evaluate the association between BMI and myopia.

Results

The incidence of myopia was 39.4%. BMI was correlated with myopia, with each 1 kg/m² increase in BMI associated with a 1% increase in the risk of myopia (OR, 1.01; 95%
