| Popis: | The aim of this study was to evaluate the effects of a nutrition education program (NEP) on anthropometric, dietetic, and metabolic parameters in high-risk subjects for type 2 diabetes mellitus. Fifty-one participants, both sexes, were randomly assigned to either the control (58.8%) or the intervention (NEP) group. The intervention group received frequent individual and group nutritional counseling from a team of nutritionists. Participants were assessed at baseline (M0) and after 12 months (M1) for anthropometric, dietetic, and metabolic parameters. The hypothesis was that high-risk subjects for type 2 diabetes mellitus participating in NEP would show an improvement in these parameters. At M1, the intervention group showed a significant decline in body weight (−3.4%), body mass index (−5.7%), cholesterol intake (−49.5%), fasting glycemia (−14.0%), fasting insulin (−9.0%), postprandial glycemia (−21.0%), postprandial insulin (−71.0%), total serum cholesterol (−23.0%), and glycated hemoglobin (−24.0%). A decrease in energy intake (5%, P = .06) and low-density lipoprotein cholesterol (25%, P = .07) was observed in the interventional group, although it did not reach statistical significance. In contrast, the control group presented a significantly higher energy intake (19%, P = .04) and a nonsignificant increase in consumption of all macronutrients. The long-term NEP was found to improve anthropometric, dietary, and metabolic parameters in high-risk subjects for type 2 diabetes mellitus. |
