Diabetes Glycemic Control in Adults With Type 2 Diabetes Mellitus and ADHD.

Abstract

Introduction: Persistence in treatment is important in balancing diabetes and preventing complications. ADHD impairs quality of life and functioning in many areas of life. The aim of this study is to evaluate the possible association of ADHD and diabetes glycemic control among adults with type 2 diabetes mellitus (T2DM).

Methods: All data were obtained from Maccabi Healthcare Services (MHS) automated databases. This retrospective cross-sectional study uses electronic medical records from the Maccabi Healthcare Services database during the years 2010 to 2020. Using a propensity score with the variables of age, gender, and duration of diabetes, we compared a group of 1,582 patients with T2DM and ADHD to 1,582 patients with T2DM and without ADHD. We used a t-test to compare continuous variables and a Mann-Whitney U test for non-parametric testing. In addition, we used multivariate logistic regression with a cutoff of several HbA1c values in T2DM patients with and without ADHD during 2019 to 2020. The proportion of patients with HbA1c values above 10%, 9%, and 8% in the group of patients with ADHD was 4.7 to 5.9 times higher than in patients without ADHD. In addition, the OR in the multivariate logistic regression was 4.2 (95% CI [2.5, 6.8]), 4.3 (95% CI [3.1, 6.1]), and 2.7 (95% CI [2.2, 3.4]) for cutoff of HbA1c of 10%, 9%, and 8%, respectively.

Conclusion: Patients with co-morbid ADHD and T2DM have a higher incidence of poor glycemic control. The findings extend the knowledge on the relationship between ADHD and diabetes and highlight the need for further research to improve treatment.
