**5. Conclusions**

Global research on interventions to improve the QOL of people with diabetes gradually increased in recent decades, with major contributions from HICs. Community- and family-based interventions, including those focused on lifestyle and utilizing digital technologies, have been common. Interventions to address comorbidities in people with diabetes have also been on the rise. More contextualized interventions in LMICs, as well as regional initiatives to support LMICs in translating worldwide evidence, should be facilitated to alleviate the diabetes burden in these countries.
