目的了解河南省高海拔蒙古族老年人群翼状胬肉患病率及相关危险因素。方法2006年6月~ 2006年9月进行人口调查。采用分层、聚类、随机抽样的方法，选取年龄在40岁及以上的蒙古人2486人。翼状胬肉的诊断和临床分级为1级（透明）、2级（中级）和3级（不透明）。采用logistic回归模型评估与翼状胬肉相关的危险因素。结果2486名符合条件的受试者中，有2112名（84.9%）被检查。有378人患有单侧（n = 228）或双侧（n = 150）翼状胬肉，相当于总患病率为17.9%（95%置信区间（CI） 16.3, 19.5）。年龄越大患病率越高(chi(2)-趋势P检验
Aims To determine the prevalence and identify associated risk factors for pterygium in an elderly Mongolian population at high altitude in Henan County, China.Methods A population-based survey was conducted from June 2006 to September 2006. A stratified, clustered, random sampling procedure was used to select 2486 Mongolian people aged 40 years and older. Pterygium was diagnosed and graded clinically as grade 1 (transparent), 2 (intermediate), and 3 (opaque). Risk factors associated with pterygium were evaluated with logistic regression models.Results From 2486 eligible subjects, 2112 (84.9%) were examined. There were 378 people with either unilateral (n = 228) or bilateral (n 150) pterygia, equivalent to an overall prevalence of 17.9% (95% confidence interval (CI) 16.3, 19.5). The prevalence increased with older age (chi(2)-test of trend P
