Abstract EN
To investigate the prevalence and risk factors for pterygium in rural older adults in Shandong Province, eastern China, a population-based, cross-sectional study was performed from April to July 2008.
By means of cluster random sampling methods, a total of 19,583 people aged 50 years or above were randomly selected from four rural counties.
Out of 19,583 people, 1,767 residents were excluded mainly because they were migrant workers when this study was performed.
Finally, 17,816 (90.98%) people were included as eligible subjects.
They received a comprehensive eye examination and a structured questionnaire voluntarily.
Patients with pterygium were defined as having pterygium at the time of survey or pterygium surgery had been performed.
1,876 people were diagnosed as pterygium, either unilateral (1,083) or bilateral (793), which is equivalent to a prevalence of 10.53% (95% CI, 10.08–10.98).
The multivariate logistic regression analysis showed that pterygium was independently associated with older age, areas, outdoor time, educational level, and use of hat and/or sunglasses.
The prevalence of pterygium increased with age and hours spent under sunshine per day.
Meanwhile, the higher the educational level and the more use of hat and/or sunglasses, the lower the pterygium prevalence.
