Abstract :
Objectives The current study aimed at determining asthenopia
prevalence and its associated factors in a population of high school
students. Methods In the current cross sectional study, samples were
selected from high school students (range, 12 to 18 years) in Kermanshah
city, Iran, through stratified cluster sampling. Any person with at
least 1 symptom was considered to have asthenopia. Results Of the 1070
selected samples, 1040 participated, and examinations were completed for
901 students. The prevalence of asthenopia was 49.4% (45.7 to 53.2). The
prevalence of asthenopia was 62.8% (51.9 to 73.8) and 47.7% (43.8 to
51.7) in males and females, respectively (P = 0.013). Asthenopia
prevalence increased from 21.4% in 12-year-old to 63.9% in 18-year-old
cases (P < 0.001). The most common symptom in the study was
tearing (20.03%) and eye pain (19.88%) during near-work and reading.
Conclusions The prevalence of asthenopia in this student population was
high. Since asthenopia can interfere with near-work, its treatment
merits high importance in school-age children.
