PURPOSE. To assess the prevalence of refractive errors and associated factors in university students in urban areas of Anyang, Central China. METHODS. This is a cross-sectional university-based study of 16- to 26-year-old students in China. Subjects from two universities were invited to undergo a comprehensive eye examination. Cycloplegic refraction was acquired by autorefractor with two drops of 1% cyclopentolate. The prevalence of myopia, high myopia, hyperopia, astigmatism, and anisometropia was calculated. Only data from right eyes were included in analysis. RESULTS. A total of 7732 eligible subjects were included, with an average age of 20.2 1.4 years. Overall, the mean spherical equivalent (SE) was -2.92 +/- 2.48 diopters (D). The prevalence of myopia (SE <= -0.50 D), emmetropia, and hyperopia (SE >= +0.50 D) was 83.2%, 9.5%, and 7.3%, respectively. Female sex (OR = 1.542; P < 0.001) and science and engineering students (OR = 1.219; P = 0.004) were more likely to be myopic. The prevalence of high myopia, defined using SE <= -5.0 D, <= -6.0 D, and <= -10.0 D, respectively occurred in 20.2%, 11.1 %, and 0.5%. High myopia (SE <= -6.0 D) was statistically associated with female sex (OR = 1.202; P = 0.029) and younger age (OR = 0.896; P = 0.001). The prevalence of astigmatism (cylinder of <= -0.75 D) was 28.8%. Astigmatism was associated with male sex (OR = 0.824; P = 0.001) and younger age (OR = 0.925; P = 0.001). CONCLUSIONS. A prevalence of 83.2% for myopia and 11.1% for high myopia (SE <= -6.0 D) was found in central Chinese university students. In the future, this generation of university students may encounter long-term, vision-threatening effects, especially pathologic myopia.
