To characterize the prevalence of diabetes in a large health district in 2004 and compare it with a previous estimate made in 1996.
The study population comprised the resident population of Cardiff and the Vale of Glamorgan. Routine record linkage was used to identify patients from various sources of hospital and mortality data. Patients with diabetes were identified according to biochemistry test results, coding on routine data or attendance at a diabetes-related clinic. Diabetes-related complications were ascribed according to coding on routine data.
It was possible to identify 17 088 people with diabetes alive on 1 January 2005. Of these patients, 9064 (53.0%) were male and 8024 (47.0%) were female. Mean age (+/- sd) was 59.6 +/- 18.9 years for males and 61.2 +/- 20.4 years for females. The crude prevalence of diabetes in 2005 was 3.9% (3.4% adjusted) compared with 2.5% in 1996 (2.3% adjusted). With the exception of females aged > or = 75 years, the prevalence of diabetes increased in all age- and sex-specific subgroups. Within the 2005 cohort, over two-thirds has no recorded complications compared with approximately one half of the 1996 cohort. The prevalence of individual complications decreased, with the exception of renal complications.
The prevalence of identified diabetes appears to have increased substantially over a relatively short period of 9 years to 2004. The increase in prevalence was 46%, with an increase in numbers of patients with diabetes of 53%. A number of factors are likely to have contributed to this, including an increase in case ascertainment.
描述 2004 年在一个大型卫生区的糖尿病流行情况，并将其与 1996 年的先前估计进行比较。
研究人群包括加的夫和格伦摩根谷的居民。常规记录链接用于从各种医院和死亡率数据来源中识别患者。根据生化测试结果、常规数据编码或参加糖尿病相关诊所来识别糖尿病患者。根据常规数据编码将糖尿病相关并发症归因于患者。
可以在 2005 年 1 月 1 日识别出 17088 名患有糖尿病的患者。这些患者中，9064 名（53.0%）为男性，8024 名（47.0%）为女性。男性的平均年龄（+/-标准差）为 59.6+/-18.9 岁，女性为 61.2+/-20.4 岁。2005 年糖尿病的粗患病率为 3.9%（调整后为 2.5%），而 1996 年为 2.5%（调整后为 2.3%）。除了年龄≥75 岁的女性外，所有年龄和性别特定亚组的糖尿病患病率均有所增加。在 2005 年的队列中，与 1996 年队列相比，超过三分之二的患者没有记录并发症，而 1996 年队列中有一半左右的患者没有记录并发症。除了肾脏并发症外，个别并发症的患病率有所下降。
在相对较短的 9 年时间内，到 2004 年，已确定的糖尿病患病率似乎大幅增加。患病率增加了 46%，糖尿病患者人数增加了 53%。有几个因素可能促成了这种情况，包括病例发现的增加。
