Summary: In community-dwelling adults with type 2 diabetes receiving family doctor contract services in Shanghai, a five-module family-support self-management programme (SeCe-STRIVE) improved total self-management behaviour by 12.74 points more than usual care (95% CI 10.07 to 15.40, p<0.001). Family support, family function, diabetes knowledge, and self-efficacy also improved, but HbA1c, fasting glucose, lipids, and quality of life did not change significantly.
PICO Summary
| Element | Detail |
|---|---|
| Population | 225 community-dwelling adults with type 2 diabetes receiving family doctor contract services; single-centre, parallel-group RCT in the Xietu community, Xuhui District, Shanghai, China. |
| Intervention | SeCe-STRIVE family-support self-management programme (five modules: systematic evaluation, core education, self-directed planning, triple feedback, habit development); n=113. |
| Comparison | Standard community-based follow-up management programme for type 2 diabetes (usual care); n=112. |
| Outcome | Primary: total self-management behaviour score improved by 12.74 points more than control (95% CI 10.07 to 15.40, p<0.001), with gains across diet, exercise, glucose monitoring, foot care, and medication adherence. Secondary: significant improvements in family support, family function, diabetes knowledge, and self-efficacy. Quality of life and biochemical markers (HbA1c, fasting glucose, blood lipids) showed a downward trend but did not reach statistical significance. No ARR/NNT reported; outcomes were continuous behavioural scores, not events. |
Family-based self-management in type 2 diabetes
RCT · type 2 diabetes · 6 months
A family-based program raised self-management behaviour scores by 12.74 points versus usual care, but did not significantly improve HbA1c or other metabolic markers.
Expert Commentary
This trial offers reasonable evidence that engaging the family unit can shift self-management behaviour in type 2 diabetes, with a primary effect of 12.74 points that is both statistically significant and clinically plausible. The signal is reinforced by consistent improvement across every behavioural dimension and by parallel gains in family support, family function, knowledge, and self-efficacy. The verdict, however, must be tempered: behaviour change was demonstrated, but glycaemic and metabolic benefit was not. HbA1c, fasting glucose, and lipids drifted downward without reaching significance, so the programme should presently be regarded as improving the process of self-care rather than proven to alter disease control. The single most important limitation is the open-label design, unavoidable for a behavioural intervention but one that exposes the self-reported primary outcome to expectation and reporting bias, an effect that may be inflated when participants know they are receiving extra attention. Single-centre recruitment within one Shanghai community, where collective family responsibility is culturally embedded, further limits transportability. Can I use this with my patients? Cautiously yes, for motivated patients with engaged household support who need a structured behavioural scaffold, but not yet as a tool expected to lower HbA1c on its own. Larger multi-centre trials with longer follow-up and objective glycaemic endpoints are needed before family-based programmes are positioned as disease-modifying.
