Based on past survey data, this research investigates if there exists relationship between the myopia progression and urban-rural gap in Taiwanese students aged between 7 and 15.
Methods
Four nation-wide surveys of myopia refraction status of students in Taiwan were conducted in 1996, 2000, 2005, and 2010. Summary statistics about the degree of myopia, including the average and standard error have been provided in those reports. We used the reported statistics and the weighted linear regression model to examine the factors affecting the myopia and the relationship between myopia progression and urban-rural gap in Taiwan.
Results
Students of higher age and living in city usually have a higher degree of myopia. In addition, the urban-rural gap is associated with the degree of myopia. However, in recent surveys, the urban-rural difference has decreased. According to our regression model, we also found that the Developmental Grading of the city can be divided into three groups, instead of the ten stratifications in previous surveys.
Conclusion
Age, survey-year, and Developmental Grading of the city are associated with the degree of myopia progression. However, the urban-rural gap is less obvious in recent surveys. In particular, the gap affects the myopia progression more for junior high school students than elementary school students. In addition, for future nation-wide myopia survey, we suggest stratify areas into three than ten groups, since the difference among the original ten areas was not substantial.
