Aims: We investigated the effect of continuous glucose monitoring (CGM) with personalised structured education on patients with type 2 diabetes (T2D) and pre-diabetes in a workplace setting. Materials and Methods: This 8-week prospective study enrolled adults with T2D or pre-diabetes at Samsung Electronics Device Solutions between March and September 2023. Participants underwent CGM (Freestyle Libre) for 2 weeks and received personalized structured education on diet and physical activity. The primary outcome was the change in HbA1c level at 8 weeks compared with baseline. Secondary outcomes included changes in fasting blood sugar (FBS), lipid profile, weight and patient-related outcome measures (PROMs) at 8 weeks and longer. Results: Among 234 participants (161 T2D and 73 pre-diabetes), significant improvements were observed in the T2D group patients in terms of HbA1c (6.9% +/- 1.2%-6.5% +/- 0.8%), FBS (128.4 +/- 36.9-117.6 +/- 22.2 mg/dL), weight (81.9 +/- 13.5-80.7 +/- 13.6 kg) and low-density lipoprotein (LDL) cholesterol (106.0 +/- 41.5 to 95.1 +/- 35.9 mg/dL) (all p < 0.001) levels. Meanwhile, patients with pre-diabetes showed significant improvements in weight (79.7 +/- 14.0-78.5 +/- 13.9 kg) and LDL cholesterol (124.5 +/- 32.8-113.8 +/- 29.1 mg/dL) (all p < 0.001), with no significant changes in HbA1c or FBS. These improvements were maintained during follow-up check-ups after a mean of 6.4 months. Participants in both groups demonstrated improvements in their PROMs. Conclusions: 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.
