    在最新的一期《糖尿病护理》杂志上研究者分析了来自中国162个地区的超过98000人的数据，通过数据分析和处理得出了中国糖尿病各区域性的患病率和发生率。

    新结果来自全国健康普查的中国疾病监测点（DSP）系统数据，其覆盖了中国人口的7%.这项研究的一个重要方面是它把人群水平与地理信息数据相结合，从而对中国糖尿病发生的决定因素提供了一个微妙的角度。

    糖尿病患病率的数据（诊断和未确诊的）表明，城市比农村人更倾向于患糖尿病。在北京，患病率为15.4——22.1%,而在**，患病率为5.4——9.2%.这些发现表明，在中国的经济优势或富裕地区糖尿病更常见。虽然个人层面因素如健康认知力可减弱地理位置和糖尿病患病率之间的相关性，在省，城里和村庄水平的变化还是有意义。

    糖尿病患病率存在差异的因素还包括被确诊糖尿病的人口比例，这在城市和农村之间存在较大差距，与城市人群相比，农村人群不太可能被确诊。校正个人水平因素对结果只有轻微的影响，研究表明中国糖尿病诊断和治疗的客观资源分配应关注在农村糖尿病确诊率低方面。

    Extensive Geographic Variation in Diabetes Ascertainment in ChinaData from more than 98,000 Chinese **s living in 162 areas across China provide new detail on the landscape of diabetes prevalence and ascertainment in this large and diverse country. The new report （p. 72） relied on data from China's National Disease Surveillance Point （DSP） System, a nationally representative health survey that covers 7% of China's population. This survey contains ***rmation for physician-diagnosed diabetes as well as blood specimens that were used to determine respondents with undiagnosed diabetes. An important aspect of the new research is that it combines person-level data with geographic ***rmation, thereby providing a nuanced perspective on the determinants of diabetes across China. Data on diabetes prevalence （diagnosed plus undiagnosed） showed that urban areas tended to have more diabetes than rural ones. In Beijing, prevalence ranged from 15.4 to 22.1%, whereas in Tibet, prevalence was 5.4–9.2%. These findings support the idea that in China, diabetes is more common in areas that are characterized by greater economic advantage or affluence. Although person-level factors such as health literacy attenuated the association between geographic location and diabetes prevalence, there was still meaningful variation at the provincial, town, and village levels. A different picture emerged for diabetes ascertainment—the proportion of people with diabetes whose condition was diagnosed. There were considerable disparities between the rural and urban areas, with people in rural areas being considerably less likely to be diagnosed than their urban counterparts. Adjustment for person-level factors had only a minor influence on these findings, an observation suggesting that one objective of resource allocation for diabetes diagnosis and treatment in China should focus on reducing the gap of diabetes ascertainment in rural areas. — Helaine E.
