Conclusions:
These findings demonstrate a significantly higher proportion of medication non-adherence among individuals with diabetes in LMIC settings when MMAS-8 item scale was used and low when 80-90% cut-off scales were used. Various factors, such as disease factors, therapy-related factors, healthcare system factor, patient-centered factors, and social and economic factors contributed to non-adherence. Therefore, comprehensive multifaceted strategies are urgently needed to address factors associated with anti-diabetic medication non-adherence.
