(1) to describe pediatric patients with T1D and their caregivers' perceptions of measures of glycemic control (hemoglobin [A1C] and blood glucose [BG] levels) and (2) to determine the relationship between patients' and caregivers' perceptions of measures of glycemic control with actual A1C levels and adherence to diabetes self-care behaviors.
Patients (8 to 18 years) with T1D and caregivers completed questionnaires that queried their perceptions of (1) what the A1C level assesses, (2) the ideal A1C target, and (3) the ideal BG range. Point-of-care A1C levels were measured for each patient. They also completed the Self-Care Inventory Revised (SCI-R) to assess adherence to diabetes self-care behaviors.
Among 253 dyads, the frequencies of patients compared to caregivers who could accurately describe what the A1C level assesses, identify the ideal A1C target, and identify the ideal BG range were 20 vs. 66, 31 vs. 56, and 72 vs. 76%, respectively. Patients' accuracy in reporting ideal targets for glycemic control was significantly associated with caregivers' accuracy. There was a trend for lower median A1C levels in patients who were part of a dyad wherein both had accurate perceptions of glycemic control.
Patients and caregivers had accurate knowledge of ideal BG range but were less knowledgeable about the meaning of A1C levels and ideal A1C targets. Nevertheless, whether glycemic control was perceived as an A1C measurement or a BG range, A1C levels trended lower for patients when both they and their caregivers had accurate perceptions of glycemic control.
(1)描述 T1D 患儿及其照顾者对血糖控制(血红蛋白[A1C]和血糖[BG]水平)衡量标准的认知;(2)确定患儿及其照顾者对血糖控制衡量标准的认知与实际 A1C 水平和遵守糖尿病自我护理行为之间的关系。
8 至 18 岁的 T1D 患儿及其照顾者完成了调查问卷,询问了他们对(1)A1C 水平评估的内容、(2)理想的 A1C 目标和(3)理想的 BG 范围的看法。对每个患者进行了即时 A1C 检测。他们还完成了自我护理量表修订版(SCI-R),以评估遵守糖尿病自我护理行为的情况。
在 253 对患儿和照顾者中,能够准确描述 A1C 水平评估内容、识别理想 A1C 目标和理想 BG 范围的患儿比例分别为 20%和 66%、31%和 56%、72%和 76%。患儿报告血糖控制理想目标的准确性与照顾者的准确性显著相关。在 A1C 水平较低的患者中,当患儿和照顾者对血糖控制的认知均准确时,中位数 A1C 水平呈下降趋势。
患儿和照顾者对理想 BG 范围有准确的认识,但对 A1C 水平和理想 A1C 目标的意义了解较少。然而,无论将血糖控制视为 A1C 测量值还是 BG 范围,当患儿及其照顾者对血糖控制的认知均准确时,其 A1C 水平呈下降趋势。
