abstract
The purpose of this study was to examine the relationship of responses to a carbohydrate intolerance (CI) questionnaire to body composition and markers of health. 108 women (31.613 yrs, 34.77% body fat, BMI 25.34) donated fasting blood samples, completed a CI survey, had body composition and health measures determined, and underwent a 75g, 2h OGTT. Pearson product correlations were performed to determine correlations to CI questions. Being more than 25 lbs overweight correlated with OGTT G90 (r=0.22), G120 (r=0.25), glucose AUMC (r=0.19), age (r=0.43), weight (r=0.57), waist circumference (r=0.66), hip circumference (r=0.59), BMI (r=0.72), fat mass (r=0.60), body fat % (r=0.51), and insomnia (r=0.30). Being overweight throughout their life correlated with OGTT G30 (r=0.28), glucose AUC (r=0.20), weight (r=0.47), waist (r=0.31) and hip circumference (r=0.49), BMI (r=0.44), BMC (r=0.33), FFM (r=0.31), fat mass (r=0.42), body fat % (r=0.31), and fatigue/exhaustion (r=0.21). Being overweight since youth correlated with OGTT G30 (r=0.28), G60 (r=0.24), G90 (r=0.22), glucose AUC (r=0.24), weight (r=0.35), waist circumference (r=0.22), hip circumference (r=0.36), BMI (r=0.32), BMC (r=0.32), FFM (r=0.25), fat mass (r=0.30), and body fat % (r=0.22). Poor appetite and skipping meals correlated with the glucose/insulin ratio (r=0.22), height (r=0.22), and BMI (r=0.20). Results revealed that CI questions moderately correlated with body composition, health markers, and/or questions related to CI.Grant Funding Source: Curves International, Inc. (Waco, TX)
