The adjusted percentages of adults reporting no DD was higher among those aged 65 years or older, male respondents, those with a PIR of 3.00 or higher (compared with those with a PIR of 1.00–2.99), those who did not report cost-related medication/insulin underuse, those diagnosed with diabetes of less than 15 years, those with excellent/very good/good self-reported health, and those with no diagnosed depression or anxiety (Table 2). Here, INS is linked to major depressive disorder.
