Workplace‐based continuous glucose monitoring with structured education for pre‐diabetes and type 2 diabetes: A prospective community cohort study
Authors' conclusion
Among adults with T2D and pre-diabetes, the use of CGM with structured education in a workplace-based setting helped with weight loss and improved LDL cholesterol levels in both groups, while also improving glycaemia in patients with T2D.

Main finding
As reported in the abstract
HbA1c, baseline to 8 weeks
T2D: HbA1c improved significantly (p < 0.001)
6.9% ± 1.2%-6.5% ± 0.8%
Observational data: associations, not effects.
Secondary outcomes
Fasting blood sugar (FBS) · 8 weeks
- T2D: FBS improved significantly (p < 0.001)
- 128.4 ± 36.9-117.6 ± 22.2 mg/dL
- Pre-diabetes: no significant change in FBS
Weight · 8 weeks
- T2D: weight improved significantly (p < 0.001)
- 81.9 ± 13.5-80.7 ± 13.6 kg
- Pre-diabetes: weight improved significantly (p < 0.001)
- 79.7 ± 14.0-78.5 ± 13.9 kg
LDL-C · 8 weeks
- T2D: LDL-C improved significantly (p < 0.001)
- 106.0 ± 41.5 to 95.1 ± 35.9 mg/dL
- Pre-diabetes: LDL-C improved significantly (p < 0.001)
- 124.5 ± 32.8-113.8 ± 29.1 mg/dL
Durability at follow-up · mean 6.4 months
- Improvements maintained at follow-up
Patient-related outcome measures (PROMs)
- Both groups improved in PROMs
