【摘要】 目的:调查广州铁路职工翼状胬肉的患病率,探讨翼状胬肉与环境条件、工种、性别及沙眼的关系。方法:采取整群抽样方法,以广铁集团公司45～60岁职工为对象,随机抽取了其属下5个不同单位职工进行体检。结果:实检人数1 634人,参检率92.0%,翼状胬肉患者61例,患病率为3.73%。按日照时间分组:<3 h者579例,患病12例,患病率2.07%,>3 h者1 055例,患病49例,患病率4.64%,两者比较差异有显著性。（X²=5.76,P<0.05）按家庭月收入分组,A组:>1万者150人,患病1例,患病率0.6%;B组:5千～1万者378人,患病8例,患病率2.12%;C组:<5千者1106人,患病52例,患病率4.70%,组组间AC,BC比较差异有显著性,AB间比较差异无显著性(X_AB²=0.59,P_AB>0.05X_BC²=3.91,P_<sup>BC<0.05;X_AC²=4.1,P_AC<0.05)结论:翼状胬肉患病率与日照时间、经济收入及沙眼的发生相关,与性别无相关。更多还原

【Abstract】 Objective:To investigate the prevalence rate of pterygium among the staff in Guangzhou Railway and explore the correlation between pterygium and environment,job,gender or trachoma.Methods:Targeted at workers aged 45-60 years old in Guangzhou Railway Corporation,we carried out medical examinations in its five different units randomly by cluster sampling.Then made a record according to the morphology and the grading of pterygium.Results: 1634 persons were examined,the participating rate was 92%,61 ones were found to get pterygium,and the prevalence rate was 3.73%.Grouped by sunshine duration:there are 579 persons in<3 hours group,among whom 12 ones were involved and the prevalence rate was 2.07%,while there are 1055 persons in>3 hours group,among whom 49 ones were involved and the prevalence rate was 4.64%,therefore there was significant difference between the two groups.（x =5.76,P<0.05） Then grouped according to monthly family income,Group A:Only one pterygium case was observed in this group included 150 persons whose income was more than 10 thousand yuan per month,and the prevalence rate was 0.6%;Group B:5 pterygium cases were checked out in this group consisted of 378 persons whose income ranged from 5000 to 10000 yuan per month,and the prevalence rate was 2.12%;Group C:52 pterygium cases were observed in this group comprised of 1106 persons whose income was lower than 5 thousand yuan per month,and the prevalence rate was 4.70%,significant difference could be seen when comparing Group A with Group C,Group B with Group C, respectively,however,no significant difference between Group A and B.(x_AB²=0.59,P_AB>0.05;x_BC²=3.91,P_BC<0.05;x² AC=4.1,P_AC<0.05).Conclusions:This study suggests that the prevalence of pterygium correlates to sunshine duration,economic income and trachoma incidence closely,but it shows no relation with the gender.更多还原
