Glycemic outcomes of a family-focused intervention for adults with type 2 diabetes: Main, mediated, and subgroup effects from the FAMS 2.0 RCT
Authors' conclusion
Despite improvements in most intervention targets, HbA1c improved only among PWDs engaging non-cohabitating support persons suggesting future family interventions should emphasize inclusion of these relationships. Future work should also seek to identify intervention targets that mediate improvements in HbA1c.
Study context
- Population
- Adults with T2D (with optional family/friend support person); 52 % male, 39 % minoritized race or ethnicity, mean hemoglobin A1c (HbA1c) 8.6 ± 1.7 %
- Participants
- 329 adults
- Comparison
- FAMS vs control
- Primary endpoint
- HbA1c
Primary result
As reported in the abstract
- Overall mean effects of FAMS on HbA1c were not significant
