Glycemic outcomes of adults with type 1 diabetes may be affected by depression. Our aim was to compare outcomes of “depressed” (Patient Health Questionnaire-9 ⩾ 10, N = 83) to “not-depressed” matched control (Patient Health Questionnaire-2 < 3, N = 166) adults with type 1 diabetes with objective measures. The depressed group had poorer blood glucose control and, for those with glucose meter downloads, fewer glucose tests/day. The groups did not differ on glucose variability or episodes of hypoglycemia. Depression in adults with type 1 diabetes is associated with poorer glycemic control and less blood glucose monitoring. Future research should examine whether treatment of depression results in better self-care and glycemic outcomes.

患有 1 型糖尿病的成年人的血糖结果可能会受到抑郁症的影响。我们的目的是比较“抑郁”（患者健康问卷 9 ⩾ 10，N = 83）与“不抑郁”匹配对照（患者健康问卷 2 < 3，N = 166）患有 1 型糖尿病的成人客观的措施。抑郁组的血糖控制较差，对于那些下载血糖仪的人，每天进行的血糖测试较少。各组在血糖变异性或低血糖发作方面没有差异。患有 1 型糖尿病的成年人的抑郁症与血糖控制较差和血糖监测较少有关。未来的研究应该检查抑郁症的治疗是否会导致更好的自我保健和血糖结果。
