Introduction and Objective: The Stelo Glucose Biosensor offers real-time glucose data and insights to individuals not on insulin, with or without diabetes. This study assessed early user experiences to evaluate the impact of real-time glucose monitoring on glycemic outcomes and behavior in users with no diabetes (ND), prediabetes (PreD), or Type 2 Diabetes (T2D) during the first 30 days of Stelo use.Methods: We analyzed real-world data from users during their first 30 days using Stelo, along with survey responses on behavioral intentions, reflections, and changes. Demographics, glycemic metrics, and engagement data including behavior logging (BL) to contextualize spike notifications were analyzed over 30 days by user subgroups and stratified by median BL engagement. Changes were compared between the first and last 10 days.Results: Sample included 481 users (38% aged 65+ years; 49% female; BMI 29±6 kg/m2; 29% ND, 26% PreD, 45% T2D). Mean glucose increased progressively from ND to T2D (30-day mean ± SD mg/dL: 108 ± 15, 116 ± 17, 145 ± 28), while TIR 70-120 mg/dL declined (80± 19, 67± 23, 30 ± 26) (all p <0.001). TIR was high across user groups; PreD and T2D users showed the most improvements over time, with TIR increases over wear period, trends that, while not statistically significant, are noteworthy. TIR was significantly higher among users with above-median BL engagement than those with below-median engagement (88 ± 18 vs 93 ± 14; p <0.05). While all users prioritized glucose monitoring and diet, ND and PreD users more often pursued sleep, stress, and activity goals (p<0.05). Users reported increased knowledge and confidence around health management, and positive changes in diet, activity, and weight management.Conclusion: Stelo supported behavior change and improved physical health and psychological well-being across populations with diverse glycemic patterns. These findings support its broader use in lifestyle and metabolic health management.
