STUDY ON THE PREDICTION OF HYPERGLYCEMIA ACCORDING TO THE DURATION OF VEGAN DIET IN FEMALE
Objectives: To determine the prediction of hyperglycemia according to the duration of vegan diet in female. Materials and Methods: 144 female vegans aged from 20-75 with duration of vegan diet ranged 1070 years, mean 27.8±15.9 years that were screened for carbohydrate dysmetabolism. They were compared with 68 women with aged from 22-84 non-vegetarian diet. Results: The average fasting glucose in female Vegan group was higher than in control group (5.00 ±1.40 vs 4.67 ± 0.98 mmol/l, p<0.05). The prevalence of hyperglycemia (based on fasting glucose) in female Vegan group was higher than in control group (13.2% vs 10.3%, p < 0.05). Especially, there were significant differences in HbA1c levels between two groups. The average HbA1c in female Vegan group was higher than in control group (5.9 ±0.9 so với 4.3 ± 0.90%, p < 0.05). The prevalence of hyperglycemia (based on HbA1c) in vegan group was higher than in control group (45.1% vs 13.2%, p < 0.05); prediabetes was 34% in Vegan group and 10.3% in control group. There were correlations between duration of vegan diet and FG (r = 0.312), HbA1c (r = 0.403), in which the duration of vegan diet was considered as an independent risk factor for hyperglycemia. Prediabetes was 18 yrs and diabetes was 42 yrs of vegan diet duration. Conclusions: Vegan diets in women can predict hyperglycemia after an 18-year period. Key words: duration of vegan diet, hyperglycemia, HbA1c
