虽然影响与许多糖尿病结局有关，但积极影响（PA）在HbA1c中的具体作用尚不清楚。本研究考察了PA是否能预测成人2型糖尿病患者的HbA1c降低，以及压力是否能调节这种关系。参与者是123名最近诊断为2型糖尿病的成年人（女性44.7%，白人60.2%，黑人39.8%）。在基线时评估感知应激、糖尿病特异性应激和PA；在基线（T1）、6个月（T2）和5年（T3）时评估HbA1c。PA横断面与T1时较低的HbA1c相关，并预测T3时较低的HbA1c。PA与T1应激的两种测量相互作用来预测T1 HbA1c， PA与T3感知应激相互作用来预测T3 HbA1c。相互作用与应力缓冲一致。敏感性分析削弱了研究结果，但仍有强有力的证据表明，五年后，PA是血糖的保护因素，并且PA对糖尿病特异性应激有应激缓冲作用。研究结果表明，PA可能是成人2型糖尿病患者的临床有用指标，对那些因疾病而承受最大压力的人尤其重要。在线版本包含补充材料，可在10.1007/s10865-023-00408-8获得。
While affect is linked to a number of diabetes outcomes, the specific role of positive affect (PA) in HbA1c remains unclear. The present study examined whether PA prospectively predicted lower HbA1c among adults with type 2 diabetes and whether this relation was moderated by stress. Participants were 123 adults (44.7% female; 60.2% White, 39.8% Black) recently diagnosed with type 2 diabetes. Perceived stress, diabetes-specific distress, and PA were assessed at baseline; HbA1c was assessed at baseline (T1), six months (T2), and five years (T3). PA was cross-sectionally associated with lower HbA1c at T1 and prospectively predicted lower HbA1c at T3. PA interacted with both measures of T1 stress to predict T1 HbA1c, and PA interacted with T3 perceived stress to predict T3 HbA1c. Interactions were consistent with stress buffering. Sensitivity analyses attentuated findings, but robust evidence remained for PA as a protective factor for blood glucose five years later and for a stress-buffering effect of PA on diabetes-specific distress. Findings suggest PA may be a clinically useful indicator among adults with type 2 diabetes and may be particularly important for those experiencing the greatest stress from their disease.
