目的：评估估计血糖值与血糖仪测量值之间的差异以及对 2 型糖尿病患者自我护理行为的影响。研究设计和方法：参加“控制糖尿病”会议的 18 岁以上 2 型糖尿病受试者 (N = 297) 被问及有关糖尿病管理的问题，并估计他们当前的血糖。研究人员在血糖仪上测试了受试者的血糖。看到结果后，受试者再次被问及有关糖尿病管理的问题。 主要结果指标：受试者血糖估计值超出 ISO 15197:2003 准确度标准的百分比（>+ 15 mg/dL 或 >+20% 血糖值）。结果：近一半 (46%) 的受试者估计血糖值超出 ISO 15197: 2003 准确度标准。距上次血糖测试的时间、距上次进餐的时间、测试频率和 A1C 对血糖估计值和血糖仪结果之间的差异没有影响。在血糖测试前的问卷中，大多数受试者强烈同意、同意或既不同意也不反对“即使我没有测试血糖，我也会做出关于我的糖尿病的决定，例如我的食物摄入量或胰岛素剂量”(71%)和“我的身体在不测试血糖的情况下告诉我我的血糖是低还是高”(77%)。血糖检测后，99%的受试者强烈同意、同意或既不同意也不反对“通过检查了解我的血糖可以帮助我做出不同的糖尿病决策”。 结论：自我监测血糖是糖尿病自我管理的重要组成部分。测试而不是猜测血糖值对于获得准确的结果并告知 2 型糖尿病患者做出有效、适当的糖尿病管理决策非常重要。这项研究的一个潜在局限性是受试者人群可能不能代表糖尿病患者的一般人群；然而，会议的设置可能会吸引更有积极性的人群，这可能会低估会议成果的重要性。
Objective:To assess differences between estimated blood glucose values and those measured on a blood glucose meter and the impact on self-care behavior in type 2 diabetes.Research design and methods:Subjects >= 18 years with type 2 diabetes (N = 297) attending a Taking Control of Your Diabetes conference were asked questions about diabetes management and to estimate their current blood glucose. Study staff tested subjects' blood glucose on a meter. After seeing the result, subjects were again asked questions on diabetes management.Main outcome measure:The percentage of subject blood glucose estimations that were outside ISO 15197:2003 accuracy criteria (>+ 15 mg/dL or >+20% of meter glucose values).Results:Nearly half (46%) of subjects estimated blood glucose values outside ISO 15197: 2003 accuracy criteria. Time since last blood glucose test, time since last meal, testing frequency, and A1C did not have an effect on differences between estimated blood glucose values and meter results. In the questionnaire before blood glucose testing, most subjects strongly agreed, agreed, or neither agreed nor disagreed that 'I make decisions about my diabetes, such as my food intake or my insulin dose even when I do not test my blood sugar' (71%) and 'My body tells me without testing if my blood sugar is low or high' (77%). After blood glucose testing, 99% of subjects strongly agreed, agreed, or neither agreed nor disagreed that 'Knowing my blood sugar by checking could help me make different diabetes decisions'.Conclusions:Self-monitoring of blood glucose is an important component of diabetes self-management. Testing rather than guessing blood glucose values is important to obtain accurate results and inform people with type 2 diabetes to make effective, appropriate diabetes management decisions. A potential limitation of this study is that the subject population may not be representative of the general population of people with diabetes; however, the conference setting may attract a more motivated population, which could underestimate the magnitude of the results.
