Summary:In adults with uncontrolled type 2 diabetes in China, a mobile app-based intervention
significantly improved HbA1c and systolic blood pressure (SBP) compared to usual care,
though it was associated with minor usability challenges related to app adherence.

| PICO | Description |
|---|---|
| Population | Adults with uncontrolled type 2 diabetes (HbA1c >7.5% and elevated cardiovascular risk factors) in China. |
| Intervention | Mobile message-based intervention designed to promote better self-management of diabetes and cardiovascular health through educational and motivational text messaging. |
| Comparison | Usual care, which consisted of standard medical and dietary recommendations without mobile intervention support. |
| Outcome | The mobile intervention was associated with modest reductions in HbA1c (-0.4%) and systolic blood pressure (-3.8 mmHg) compared to usual care. There were no significant adverse effects, but adherence to app use was variable among participants. |
