A Study of Glycemic Index, Glycemic Load and Food Sources according to Body Mass Index in Female College Students / 대한지역사회영양학회지

ABSTRACT

The purpose of this study was to evaluate nutrients intakes, glycemic index (GI), glycemic load (GL) according to body mass index (BMI) in female college students (n = 320). The study subjects were divided into 3 groups based on their body mass index, an underweight group (BMI < 18.5 kg/m2, n = 55), a normal group (18.5 kg/m2 < or = BMI < 23 kg/m2, n = 231), and an overweight group (23 kg/m2 < or = BMI < 25 kg/m2, n = 34). The food and nutrition intake data obtained by administering a 3-day food record and were analyzed by using Can pro 3.0 software. Anthropometric measurements were collected from each subject. Body weights and BMI of the underweight group were 45.9 kg, 17.6 kg/m2, those of the normal group were 53.8 kg, 20.5 kg/m2, and those of overweight group were 62.6 kg, 23.8 kg/m2, respectively. The mean daily dietary GI of underweight, normal and overweight groups was 66.2, 65.8 and 66.5, respectively. These differences were statistically non-significant. The mean daily dietary GL of underweight, normal and overweight groups were 159.2, 149.4, and 148.9, respectively. The major food source of dietary GI and GL was rice in the three groups. Dietary GI and GL were not significantly correlated with obesity when adjusted for energy, carbohydrate and dietary fiber intake.
