摘　　要：目的:调查宁夏地区翼状胬肉的患病率,探讨翼状胬肉与年龄、性别、城乡、地理位置、种族及不同经济发展水平等人群因素间的关系。方法:利用分层、多级随机抽样的方法,抽取宁夏银川市金凤区和红寺堡两地区3001例受检对象进行眼部检查,填写翼状胬肉患病率调查表。分析宁夏地区翼状胬肉患病率及易感因素。结果:宁夏地区人群中翼状胬肉患病率为6.16%。城市和农村的患病率分别为5.74%,6.49%,两组间比较差异无统计学意义(χ2=0.717,P=0.397)。男女两组患病率分别为6.30%,6.82%,两组间比较差异无统计学意义(χ2=0.269,P=0.604)。汉族和回族患病率比较差异无统计学意义(χ2=1.641,P=0.440)。农村人群中26～45岁组,≥66岁组翼状胬肉患病率高于城市,差异有统计学意义。结论:宁夏地区翼状胬肉的患病率较高与该地区的地理位置、气候条件有关。汉族与回族、城乡之间患病率无明显差异。农村人群翼状胬肉的患病率有随年龄增长而增高的趋势。病程的长短与经济发展水平相关。AIM：To determine the prevalence rate of pterygium in Ningxia region and to explore the risk factors such as age,gender,the urban-rural difference,geographical position,nationality,economic level and demographic factors·METHODS：Totally 3001 residents were selected by cluster randomized sampling in Jinfeng district and Hongsipu town.Ocular exanmination and questionnaire survey were conducted.The prevalence rate and incidence of pterygium were calculated and the related risk factor was analyzed·RESULTS：The prevalence rate of pterygium was 6.16%in Ningxia region and 5.74%in urban,6.49%in rural area,difference between the two groups was not statistically significant（χ^2 = 0.717,P=0.397）.As for 26-45 age group and more than 66 age group,the prevalence rate in rural area was significantly higher than urban area.No significant difference was found between male（6.30%） and female（6.82%）（χ^2=0.269,P=0.604）,the same as that between Hui and Han nationality（χ^2=1.641,P=0.440）·CONCLUSION： The higher prevalence rate of pterygium in Ningxia is attributed to geographical position and climate condition,but not significantly associated with gender and nationality.Regarding to rural residents,the prevalence rate is higher in aged group.The course of disease is related to the economic level.
