Visceral Fat Level Correlate with Increase of Fasting Blood Glucose in Overweight and Obese Adult

Abstract

Overweight and obesity is a condition of excess body fat that can increase flux of free fatty acid that effect insulin sensitivity which is risk factor for increased fasting blood glucose levels (FBG) or diabetes. This study aims to evaluate correlation of body fat indicator, body mass index (BMI) and physical activity (PA) with fasting blood glucose in overweight and obese adult. Total of 75 adult ranging from 20-57 years with BMI ≥ 25 kg/m2 were recruited. Anthropometric measurements including body weight, percent body fat (BF) and visceral fat level (VF) were measured using Biolectrical Impedance Analysis (BIA) method. Physical activity determined with International Physical Activity Questionnaire (IPAQ). Fasting blood glucose were analysed using hexokinase method. There is significant different of BF, VF and level of physical activity in men and woman (p=0.000). Age was positively correlated with VF (r=0.219;p=0.059) and FBG (r=0.307; p=0.007). There is not correlation between PA and FBG. VF showed a positive correlation with FBG (r=0.229; p=0,048). Fasting blood glucose increases with age and visceral fat in overweight and obese adult. Control of body weight and routine measurement of body fat is important for reduce diabetes risk in adult above 40 years old.
