Introduction: Diabetes Mellitus is a metabolic disease that occurs due to several risk factors, including obesity and occupation. Measurement of neck circumference, waist circumference, and waist to hip ratio (WHR) are obesity indicator methods that are suspected to be related to diabetes mellitus. This study aimed to determine the correlation between neck circumference and WHR with fasting blood glucose levels in security officers. Methods: A cross-sectional study included 92 male security officers aged 20 – 45 years chosen with purposive sampling methods from Diponegoro University. All subjects were asked to fast and take no medications for the previous 8 hours before their venous blood plasma samples were taken for testing. Subjects were categorized based on their nutritional status, namely Body Mass Index (BMI), Neck Circumference and Waist to Hip Ratio (WHR). Neck circumference and WHR were measured using a non-stretchable plastic replicated twice to obtain the mean value. Data were analyzed using Spearman’s test. Results: This study found that 9.8% subjects were categorized as obese (BMI  30 kg/m2), subjects who had a high fasting blood glucose level ( 110 mg/dl) was found 4.3% or about 4 male security officers , 41.3% subjects had a neck circumference  38 cm and 29.3% subjects had WHR  0.9. Conclusion: There was a positive correlation between WHR and blood glucose levels (r=0.254 and p=0.015). Also, neck circumference was found to be significantly associated with blood glucose (r=0.454 and p<0.001).
