方法：采用整体随机抽样的方法，对上海淞南社区的糖尿病者进行全身体检。免散瞳眼底照相了解DR患病率。填写调查问卷了解其一般情况和对DR的认知度情况。

结果：共收集有效调查问卷和眼底照相1 120份。糖尿病者DR患病率为23.6%，其中轻度DR 17.1%，中度DR 5.1%，重度DR1.4%。最近1a中做过眼科检查者14.1%； 知道空腹血糖正常值者占71.5%； 85.7%的患者知道糖尿病会引起全身并发症； 77.2%的患者知道有眼部并发症； 47.9%的患者知道需要定期检查眼底； 58.0%的患者知道早期治疗DR是防治视力损伤的重要手段； 59.9%的患者愿意定期参加健康宣教讲座。单因素相关分析提示：对DR知识认知度得分与年龄、文化程度、医保类型、糖尿病病程、是否控制饮食、是否监测血糖、空腹血糖水平、锻炼频次和DR分期相关。Logistic回归分析提示对DR知识认知度得分的影响因素为：年龄、文化程度、医保类型、糖尿病病程、是否控制饮食、锻炼频次和DR分期。

结论：淞南社区糖尿病者对DR防治知识的认知度尚不足，认知没有完全付诸行动，对社区糖尿病者进行有针对性的DR防治知识宣教很有必要。

METHODS: Residents with diabetes mellitus were randomly sampled in Shanghai's Songnan Community. These patients received full physical examinations. DR was diagnosed using non-mydriatic fundus photography. The patients completed a survey concerning their general knowledge and awareness of DR.

RESULTS: A total of 1120 valid questionnaires and fundus photographs were collected. The incidence of DR among patients with diabetes was 23.6%; 17.1% had mild DR, 5.1% had moderate DR and 1.4% had severe DR. Of the survey participants, 14.1% received ophthalmic examinations over the last year, 71.5% knew their normal blood glucose levels, 85.7% were aware of the possibility of systemic complications caused by diabetes, 77.2% were aware of ocular complications, 47.9% were aware of the need for regular fundus examinations, 58.0% were aware that the early treatment of DR is an important measure to prevent visual impairment, and 59.9% were willing to participate in regular health education seminars. A univariate analysis indicated that the knowledge and awareness scores regarding DR were correlated with age, education level, type of medical insurance, duration of diabetes, diet control, blood glucose monitoring, fasting blood glucose level, exercise frequency and DR stage. A logistic regression analysis indicated that the factors affecting the DR awareness scores were age, education level, type of medical insurance, stage of diabetes, diet control, exercise frequency and DR stage.

CONCLUSION: The patients with diabetes in the Songnan Community lacked sufficient awareness of DR prevention and treatment methods. The existing awareness of DR among the survey participants did not lead to effective prevention or treatment actions associated with this condition. It is necessary to educate patients with diabetes in local communities regarding DR.
