They may: more time above 140 mg/dL was the strongest sign of worsening blood sugar over six months in a small study of kids. The study followed 29 young people, ages 10–18, with obesity and prediabetes. Their starting HbA1c (Hemoglobin A1c) results ranged from 5.7% to 6.4%. They had blood tests and wore glucose sensors for 14 days. Researchers repeated these checks at the six-month follow-up. The sensors tracked Real-Time Glucose (CGM), showing sugar patterns throughout the day. Most blood test results and sensor readings stayed stable. 32% returned to normal blood sugar levels. One young person reached an HbA1c (Hemoglobin A1c) of 6.5%. That person had notably high sensor readings at the start. Several sensor measures were linked to later blood test results. But time above 140 mg/dL stood out after researchers accounted for other health factors. It was the only measure that consistently predicted both higher follow-up results and worsening over time. Overall, sensor measures predicted short-term changes better than the starting blood test alone. This is a useful clue, not a sure forecast. The study was small and lasted just six months. It did not test whether using a sensor prevents diabetes. Its findings also cannot be assumed to apply to adults. For BioSocial members tracking both measures, the takeaway is about comparing patterns. A lab result and a sensor report may tell different parts of the story. Sharing dated results and time above 140 mg/dL could make community comparisons more useful. This study did not set a personal target for that time. What have you noticed when comparing your sensor patterns with your later blood test results?
