Abstract

Objective: To investigate the association between carbohydrate intakes and beta-cell function (HOMA-beta) in Japanese-Brazilians with impaired glucose tolerance (IGT). Methods: Dietary intakes were assessed by a validated food frequency questionnaire in a cross-sectional survey carried out in 2000. The associations between diet and HOMA-beta were verified in 270 newly diagnosed IGT in multiple linear regression models. Results: The mean (SD) age was 58 (11) years and the mean HOMA-beta was 65 (47). The glycemic load was inversely associated with HOMA-beta, beta 1 -0.140 (95% CI = -1.044; - 0.078), p = 0.023. The inverse association was also observed for refined grains intakes: -0.186 (95% CI = - 0.4862; -0.058), p = 0.012. After adjustments for body mass index, the glycemic index was inversely associated with HOMA-beta: -0.1246 (95% CI = -2.2482, -0.0257), p < 0.001. Conclusions: These data suggested that dietary glycemic load, glycemic index, and refined grains intakes are associated with reduced beta-cell function, and the quality of dietary carbohydrates may be relevant for maintaining beta-cell function among individuals with IGT.
