Current status of vision and refractive errors among children and adolescents in northeast Sichuan, China: a school-based cross-sectional study
To investigate the status of visual acuity and refractive errors among children and adolescents in northeastern Sichuan, emphasizing the significance of targeted myopia prevention and control.
Key Findings:
Prevalence of poor visual acuity reached 90.81% and suspected myopia nearly 90% in general senior high school students.
Suspected myopia was more common among female students.
Regional disparities were significant, with the highest prevalence in Nanbu County (80.49%) and lowest in Langzhong City (46.41%).
Urban students had a higher prevalence of myopia than township students.
Eyeglasses were the predominant method of vision correction, with increasing use correlating with education level.
Astigmatism and anisometropia were prevalent among myopic students and increased with school grade.
Interpretation:
The study highlights alarming rates of myopia and poor visual acuity among children and adolescents in northeastern Sichuan, emphasizing the need for targeted prevention strategies and their implications for public health policy.
Limitations:
The study's focus on specific regions may limit generalizability to other areas.
The sample may not fully represent preschool children due to limited participation.
Potential biases in self-reported data or participation rates may affect results.
Conclusion:
The findings provide essential data for developing targeted myopia prevention strategies in northeastern Sichuan, addressing regional disparities in visual health and underscoring the urgency of the issue.
