摘要 目的了解昆明市50岁及以上人群的盲和低视力患病率及其相关因素。方法2006年6月至8月对昆明市50岁及以上人群进行盲和低视力患病率及其相关因素调查,通过多阶段抽样法抽取样本2760人,进行基本信息调查和眼部检查。根据小孔视力和WHO视力损伤标准(标准A)和日常生活视力标准(标准B)计算盲、严重视力损伤(severe visual impairment,SVI)和视力损伤(visual impairment,VI)的患病率,盲和低视力患病率的相关因素采用STATA9统计软件进行分析。结果本调查共有2588人应答,应答率为93.8%,盲的患病率分别为3.2%(标准A)和3.7%(标准B),经年龄和性别矫正后分别为2.3%(标准A)和2.7%(标准B)。50-59岁、60-69岁、70-79岁、80岁及以上人群盲患病率分别为0.5%、2.3%、6.5%和11.0%,SVI患病率分别为0.6%、2.0%、4.5%和10.1%,VI患病率为2.1%、5.7%、14.6%和28.2%;贫困、中等收入、富裕人群盲患病率分别为4.8%、2.8%和2.7%,SVI患病率分别为2.7%、7.9%和2.2%,VI患病率为9.9%、13.0%和8.5%;城镇人口和农村人口盲患病率分别为1.6%、4.5%,SVI患病率分别为1.4%、3.6%,VI患病率为6.0%、10.4%;经过统计学分析发现,盲、SVI和VI患病率与年龄、经济状况和城乡分布显著相关,而与民族、性别不相关。结论年龄、经济状况和城乡分布是昆明市50岁及以上老年人群盲和低视力患病率的主要相关因素。 Objective To assess the prevalence of blindness and low vision and correlation factors for them in aged people and more than 50 of Kunming. Methods Prevalence of blindness and low vision and correlation factors for them were studied in aged people and more than 50 of Kunming at Jtme to August,2006. Multi-stage sanlpling i was applied to randomly select 2 750 people. Basic information and ophthalmic examination were collected from these participants. The prevalence of blindness, severe visual impairment (SVI) and visual impairment (VI) were calculated based on pinhole visual acuity, WHO definition of visual injury ( Definition A) and daily visual definition ( Definition B). The cOrrelation factors about blindness and low vision were analyzed using STATA 9. Results The response rate was 93.8% about 2 588 people. The prevalence of blindness was 3.2% with Definition A and 3.7% with Definition B, and was 2.3% with Definition A and 2. 7% Definition B after agesex adjustment, respectively. The prevalence of blindness for people aged from 50 to 59, from 60 to 69, from 70 to 79,80 and more than 80 were 0.5% , 2.3% , 6.5% and 11.0% , respectively, the prevalence of SVI were 0.6% ,2.0% ,4.5% and 10. 1% , respectively, and the prevalence of Ⅵ were 2. 1% 5.7% , 14.6% and 28.2% ,respectively. The prevalence of blindness for poor,middie-income people and wealthy people were 4.8% , 2.8% and 2.7% , respectively, the prevalence of SVI were 2.7% , 7.9% and 2.2% , respectively, and the prevalence of VI were 9.9% , 13.0% and 8.5% ,respectively. The prevalence of blindness for urban population and rural population were 1.6% and 4.5% ,the prevalence of SVI were 1.4% and 3.6% , and the prevalence of VI were 6.0% and 10.4%. Statistical analysis showed that the prevalence of blindness, SVI and VI were significantly related to age, economic conditions and urban and rural distribution, not related to ethnicity or gender. Conelusion Age, economic conditions and urban and rural distribution are the main risk factors for prevalence of blindness and low vision in aged people of Ktmming.
