Why carry out this study?

Treatment adherence and satisfaction impact the quality of diabetes care.

We investigated factors associated with treatment adherence and satisfaction in patients with type 2 diabetes (T2DM) in Japan.

What was learned from this study?

Lower age, lower household income, employment and impaired basic activity of daily living may negatively impact treatment adherence in patients with T2DM.

Receiving and understanding guidance on how pharmacologic therapies are tailored, higher household income, male sex and higher age may positively impact treatment satisfaction in patients with T2DM.

Different approaches may be effective when attempting to improve T2DM treatment adherence and satisfaction in patients aged < 65 and ≥ 65 years in Japan.
