Investigation on the prevalence and influencing factors of pterygium in Gannan ethnic minority areas

Objective To investigate and analyze the prevalence and influencing factors of pterygium in Gannan ethnic minority ar. eas.Methods Using random cluster sampling method, 8 sample areas in Gannan Tibetan Autonomous Prefecture were selected for on-site investigation in November 2021. The general data of Gannan ethnic minority areas were collected and the disease situation wascounted through self-made questionnaire, single factor and multi factor logistic regression were used to analyze the influencing factorsof pterygium occurrence in Gannan ethnic minority areas.Results There were 3 293 subjects in this study, and 405 pterygium pa.tients were detected, with a prevalence rate of 12.30%; among 405 patients with pterygium, 41 patients with pterygium of grade 1 ac.counted for 10.12%, 84 patients of grade 2 accounted for 20.74%, 253 patients of grade 3 accounted for 62.47%, and 27 patients ofgrade 4 accounted for 6.67%, there was a statistically significant difference in the distribution of pterygium at different ages (χ2=22.27, P<0.05), but there was no significant difference in the distribution of pterygium at different genders (χ2=0.39, P>0.05); the results ofunivariate analysis showed that the occurrence of pterygium in minority areas of Gannan was associated with age, history of alcohol con.sumption, hypertension, diabetes mellitus, time spent in daytime outdoor activities, wearing glasses, gender, and place of residence (P< 0.05); multivariate logistic regression analysis showed that age ≥45 years old (OR=2.98), history of alcohol consumption (OR=3.54), high blood pressure (OR=2.72), diabetes (OR=3.50), daytime outdoor activity time <3 h/d (OR=4.49), gender as female (OR=5.82) and residence in rural areas (OR=1.14) were independent risk factors for pterygium in Gannan minority areas, and wearing glasses (OR= 0.43) were protective factors for pterygium in Gannan minority areas (P<0.05).Conclusion The prevalence rate of pterygium in minor.ity areas of Gannan is 12.30%, which is associated with age, gender, history of alcohol consumption, hypertension, diabetes, time spent
