Purpose:
|
To determine the prevalence of refractive errors, among 6-15 years old schoolchildren in Dezful city in the west of Iran
|
Methods:
|
In this cross-sectional study, 1375 Dezful schoolchildren were selected through multistage cluster sampling. After obtaining written consents, participants had uncorrected and corrected visual acuity tests, cycloplegic refraction at the school site. Refractive errors were defined as myopia [spherical equivalent (SE) -0.5 diopter (D)], hyperopia (SE≥2.0D) and astigmatism (cylinder error >0.5D)
|
Results:
|
Of the 1151 study participants (83.7%), 1130 schoolchildren completed their examinations. Prevalence of myopia, hyperopia, and astigmatism were 14.9% [95% confidence interval (CI): 10.1-19.6), 12.9% (95% CI: 7.2-18.6), and 45.3% (95% CI: 40.3-50.3), respectively. Multiple logistic regression analysis showed an age-related increase in myopia prevalence (p<<0.001) and decrease in hyperopia prevalence (p<<0.001). There was a higher prevalence of myopia in boys (p<<0.001) and hyperopia in girls(p=0.007)
|
Conclusion:
|
This study showed a considerably high prevalence of refractive errors among the Iranian population of schoolchildren. The prevalence of myopia is considerably high compared to previous studies in Iran, and increases with age
