| 目的 分别调查青海省平安县和广西壮族自治区崇左市两地50岁及以上人群的年龄相关性白内障患病率，了解当地年龄相关性白内障的患病情况，并进行流行病学因素分析。
方法 采用整群随机抽样方法于2003年8月抽取青海省平安县9个自然村1486例和2004年3-4月抽取广西壮族自治区崇左市4个农业社区及自然村1344例50岁及以上人群进行问卷、视力和眼部检查，实际调查青海省平安县为1281例，应答率为86.20%，广西壮族自治区崇左市为1215例，应答率为90.40%。
结果 在青海省平安县1281例受检者中，年龄相关性白内障患病率为41.84%，使用中国2000年人口普查数据矫正后为44.07%。随着年龄的增加，患病率明显升高。在女性和文盲者中患病率较高，分别为43.69%及48.70%。按照WHO的盲与低视力的诊断标准，年龄相关性白内障导致的双眼盲占2.58%，导致的双眼低视力占7.57%。在广西壮族自治区1215例受检者中，年龄相关性白内障患病率为39.42%，使用中国2000年人口普查数据矫正后为32.78%。随着年龄的增加，患病率明显升高。在女性和文盲者中患病率较高，分别为45.83%及62.08%。按照WHO的盲与低视力的诊断标准，年龄相关性白内障导致的双眼盲占3.21%，导致的双眼低视力占7.65%。
结论 青海省平安县≥50岁老年人群的年龄相关性白内障患病率为41.84%，广西壮族自治区崇左市≥50岁老年人群的年龄相关性白内障患病率为39.42%，使用中国2000年人口普查数据矫正后分别为44.07%和32.78%，在老龄、女性及文盲中年龄相关性白内障患病率较高。

The epidemiological study of age-related cataract among adults aged 50 or above in Qinghai and Guangxi Provinces
Objective To evaluate the prevalence of age-related cataract among adults aged 50 or above in Pingan county，Qinghai province and Chongzuo county，Guangxi province，China。
Methods Cluster sampling was used for randomly selecting individuals aged 50 years or older at 9 villages in Pingan county in August 2003 and at 4 villages in Chongzuo county in March to April 2004。Individuals on roster in Pingan county was 1486，and 1281 received questionnaire，the response rate is 86.20%。Individuals on roster in Chongzuo county was 1344，and 1215 received questionnaire，the response rate is 90.40%。
Results The prevalence of age-related cataract in Pingan county was 41.84% among adults aged 50 or above。The age-adjusted prevalence of age-related cataract was 44.07% under the data of China census 2000。The age-equilibrated odds of women vs. men were 1.22。Refer to the WHO diagnostic criterion of blind and low vision，the bilateral cataract blindness was 2.58% and the bilateral cataract low vision was 7.65%。The prevalence of age-related cataract in Chongzuo county was 39.42% among adults aged 50 or above。The age-adjusted prevalence of age-related cataract was 32.78% under the data of China census 2000。The age-equilibrated odds of women vs. men were 1.36。The prevalence of age-related cataract was increasing by aging。The prevalence of age-related cataract in women and illiterates was significantly higher statistically。Refer to the WHO diagnostic criterion of blind and low vision，the bilateral cataract blindness was 3.21% and the bilateral cataract low vision was 7.65%。
Conclusions The prevalence of age-related cataract among adults aged 50 or above is 41.84% in Pingan county，Qinghai province，China and is 39.42% in Chongzuo county，Guangxi province，China。The age-adjusted prevalence of age-related cataract was 44.07% in Qinghai，and 32.78% in Guangxi under the data of China census 2000。The prevalence of age-related cataract higher in elder，women and illiterates。
