背景:糖尿病发病率可预测其发展趋势,目前国内糖尿病发病率较以前有所升高。目的:对糖耐量低减和正常人群的糖尿病发病率进行比较,分析相关影响因素的危险性。设计:以广西柳州市2个社区的成年人为研究对象的整群抽样调查。单位:一所大学医院的内分泌科。对象:1994-07/08对柳州市4个较大单位社区的人群进行糖尿病患病率调查,常住人口11886名,均为20～75岁的成年人,且在柳州市城乡居住5年以上。1999-10对其中2个单位社区的糖耐量低减和正常者进行随访,应查9230例,实查6020例,反映率65.22%(因下岗、退休等原因失访人数较多)。纳入标准:最终两次资料均完整者5539例进入统计。正常者5273例,糖耐量低减者266例;男3177例,含糖耐量低减110例,平均年龄(40±12)岁;女2362例,含糖耐量低减156例,平均年龄(41±10)岁。排除标准:继发性糖尿病。方法:1994年广西柳州市2个单位社区糖尿病患病率调查中确定为非糖尿病(包括糖耐量低减和正常人)的5539例,于1999年复查血糖、体质量指数、血压及血脂,分析各因素对糖尿病发病率的影响。主要观察指标:①终点结局指标:各年龄组糖尿病发病率。②危险性指标:糖尿病发病率相关危险因素比较。结果:纳入统计5539例。5273例正常者中,46例转变为糖尿病,年转化率为0.19%;而266例糖耐量低?
Background: The incidence of diabetes can predict its development trend. At present, the incidence of diabetes in China is higher than before. Objective: To compare the incidence of diabetes mellitus with impaired glucose tolerance and normal population, and to analyze the risk of related factors. Design: A cluster sampling survey of adults in two communities in Liuzhou, Guangxi. Unit: a university hospital endocrine department. PARTICIPANTS: A population survey of diabetes prevalence among four larger units in Liuzhou City from July to August of 2008, with a total resident population of 11,886, were adults aged 20 to 75 years and lived in Liuzhou urban and rural areas for more than 5 years. In 1999-2000, 9230 patients were surveyed with 6020 cases of impaired glucose tolerance and 65.22% of respondents (due to lay-offs, retirements and other reasons, the number of people lost to follow-up) was low. Inclusion criteria: the last two data are complete 5539 cases into the statistics. There were 5273 cases with normal glucose tolerance, 266 cases with impaired glucose tolerance, 3177 males and 110 cases with impaired glucose tolerance (mean age 40 ± 12 years), 2362 females, 156 cases with impaired glucose tolerance, and an average age of 41 ± 10) years old. Exclusion criteria: secondary diabetes. Methods: A total of 5539 cases of non-diabetic (including impaired glucose tolerance and normal) were surveyed in two community units in Liuzhou, Guangxi in 1994, and blood glucose, body mass index, blood pressure and blood lipid were reviewed in 1999 The impact of various factors on the incidence of diabetes. MAIN OUTCOME MEASURES: ① End-point outcome: The incidence of diabetes in all age groups. ② risk indicators: the incidence of diabetes-related risk factors compared. Results: 5539 cases were included in the statistics. Of the 5273 normal subjects, 46 were converted to diabetes and the annual rate of conversion was 0.19%; while 266 patients had low glucose tolerance?
