RESUMO
El objetivo de este estudio fue determinar la relación entre los parámetros de control metabólico y la calidad de los hidratos de carbono (H de C) de la dieta, en sujetos diabéticos tipo 2 (DM 2), controlados con dieta y/o metformina. A 108 hombres y mujeres con edades comprendidas entre 18 y 60 años, hemoglobinas glicosiladas (HbA1c) entre 6% y 10%, sin sulfonilureas ni insulinoterapia; se les aplicó dos encuestas de recordatorio de 24 horas. Se determinó la ingesta de H de C, el índice glicémico (IG) y la carga glicémica (CG) de la dieta. Desde las fichas clínicas se obtuvieron valores recientes de HbA1c. Los datos fueron tabulados en el programa SPSS versión 17. Se utilizó el test de correlación de Pearson para analizar el grado de asociación entre las variables, considerándose significativo un p < 0,05. El promedio de HbA1c fue de 7,3 ± 1,3 %, el consumo de H de C fue de 219,8 ± 27,0 g/día; el IG fue de 74,9 ± 11,3 % y la CG fue de 164,0 ± 22,04 g. Se encontró correlación positiva y significativa entre el consumo de H de C (r=0,290; p<0,05), IG (r=0,70; p<0,001) y CG (r=0,225; p<0,05) de la dieta con los niveles de HbA1c de los sujetos estudiados. En conclusión la calidad de los H de C, especialmente el IG, de la dieta de los sujetos estudiados se asocia fuertemente al control metabólico de la DM 2.
The Objective of this study was to determine the relationship between the parameters of metabolic control and quality of carbohydrates (CHO) of the diet in individuals with type 2 diabetes, controlled with diet and / or Metformin. In 108 men and women aged between 18 and 60 years, glycosylated hemoglobin A (HbA1c) between 6 % and 10 %, without sulfonylureas or insulintheraphy; were examined through two separate surveys of 24-hour recall. The CHO intake, GI, GL of diet was analyzed. Values of HbA1c were collected from medical records. Data was tabulated in SPSS version 17 software. The Pearson correlation test was used to analyze the degree of association between variables, considering significant at p < 0.05. The mean HbA1c was 7.3 ± 1.3%, CHO consumption was 219.8 ± 27.0 g / day; GI was 74.9 ± 11.3% and GL was 164.0 ± 22.04 g. A significant positive correlation was found out between the CHO intake (r = 0.290, P < 0.05), GI (r = 0.70, p < 0.001), GL (r = 0.225, p < 0.05) of diet and HbA1c levels in the individuals. In conclusion the study showed that the quality of CHO, mainly GI, are strongly associated with metabolic control of DM 2.
