The majority of people with prediabetes transition to type 2 diabetes. Weight gain is a known predictor of increasing the risk of diabetes, but another reason may be a focus on immediate rewards and discounting of the future. Delay discounting (DD: devaluation of future consequences) is related to obesity and poor glycemic control in persons with type 2 diabetes. This study was designed to assess whether changes in DD are associated with HbA1c change beyond BMI change in individuals with prediabetes. Hierarchical regression showed changes in BMI (p = 0.008) and the $1000 DD task (p = 0.04) were associated with HbA1c change beyond demographic characteristics, with the full model accounting for 25.8% of the variance. Those with greater BMI increases and greater increases in discounting of the future showed the greatest increases in HbA1c. DD represents a novel target to prevent progression from prediabetes to type 2 diabetes.
大多数糖尿病前期患者会发展为 2 型糖尿病。体重增加是糖尿病风险增加的已知预测因素,但另一个原因可能是关注即时奖励和对未来的贴现。延迟折扣(DD:未来后果的贬值)与 2 型糖尿病患者的肥胖和血糖控制不良有关。本研究旨在评估在糖尿病前期个体中,DD 的变化是否与 BMI 变化以外的 HbA1c 变化相关。分层回归显示 BMI 的变化(p=0.008)和 1000 美元 DD 任务(p=0.04)与人口统计学特征以外的 HbA1c 变化相关,全模型解释了 25.8%的方差。BMI 增加较多和对未来折扣增加较多的患者,HbA1c 增加幅度最大。DD 代表了预防从糖尿病前期进展为 2 型糖尿病的一个新靶点。
