Correlation Between Glycated Hemoglobin (Hba1c) Levels and Fasting Blood Glucose Levels in Patients with Diabetes Mellitus in Jambi City

Background: Diabetes Mellitus (DM) is a chronic disease of metabolic disorder characterized by blood sugar levels that increase from normal limits. It is necessary to prevent diabetes with control by monitoring metabolic status. The method that can be used in controlling blood sugar in patients with diabetes mellitus by measuring Hemoglobin-glycation (HbA1c). HbA1c measurement is the most accurate way to determine high blood sugar levels over the past 2 - 3 months. HbA1c is an examination to assess the risk of tissue damage caused by high sugar levels. The aimed of this study is to analyze the correlation between HbA1c levels ​​and blood sugar levels in patients with diabetes mellitus. Method: This study used descriptive methods with an analytical descriptive study with a cross-sectional among of 100 samples, based on the criteria of respondents who checked HbA1c and fasting blood sugar. Data analysis used the Speartam correlation test which was previously carried out by the Kolmogorov-Smirnov normality test. Result: The results of this study showed that the average  HbA1c level was 3.9% while the average  fasting blood sugar level was 82 mg/dl. There is a significant correlation between  HbA1c concentration and fasting blood sugar  with p (0.000) <  (0.05). According to the test results, the value  r = 0.666 means  the correlation is very strong (0.51-0.75). Conclusion: In conclusion, there is a strong correlation between HbA1c levels and fasting blood sugar level, the correlation happens to be positive, meaning there is a one-way relationship if HbA1c levels increases (High), fasting blood sugar levels will also increase (High). If the HbA1c levels is reduced (low), then the fasting blood sugar level is also reduced (low), and if the HbA1c level is normal, the blood sugar level is also normal.
