Factors Associated With Treatment Adherence and Satisfaction in Type 2 Diabetes Management in Japan: Results From a Web-Based Questionnaire Survey

Introduction To identify factors associated with treatment adherence and satisfaction in patients with type 2 diabetes (T2DM) in Japan. Methods A web-based questionnaire survey was conducted from 6 to 17 March 2019 in patients with T2DM aged ≥ 20 years receiving diabetes treatment. Treatment adherence and satisfaction were self-assessed/reported by the patients. A multiple logistic regression model and the chi-square test were used to assess associated factors. Results Responders ( N = 1000) were aged 63.8 (standard deviation 11.9) years, and 739 (73.9%) were male. Adherence to treatment was reported in 941 (94.1%) patients and was significantly associated with higher household income (odds ratio [OR] 2.07, 95% confidence interval [CI] 1.11–3.86), age (OR 1.04, 95% CI 1.02–1.07), employment (OR 0.30, 95% CI 0.15–0.60) and having ≥ 1 impaired basic activity of daily living (BADL) (OR 0.33, 95% CI 0.13–0.82). Satisfaction with treatment was reported by 575 (57.5%) and was significantly associated with receiving/understanding guidance on how pharmacologic therapies are tailored (OR 1.73, 95% CI 1.19–2.51), male sex (OR 1.55, 95% CI 1.10–2.19), higher household income (OR 1.45, 95% CI 1.09–1.94) and age (OR 1.02, 95% CI 1.00–1.03). Treatment adherence was negatively associated with lower household income and having ≥ 1 impaired BADL in patients aged
