Impacto da educação nutricional intensiva no controle glicêmico de pacientes diabéticos do tipo2

Abstract

We evaluated the importance of nutritional counseling, within a set of multidisciplinary interventions in 47 patients with type 2 diabetes (T2DM) and hyperglycemia (A1C . 8%), treated conventionally (n=19;GC) or intensively in six weekly visits (n = 28, GI) We evaluated the average weekly blood glucose (MWG) at baseline and after 6 weeks. The GI has reduced the caloric (p = 0.001), carbohydrate (p = 0.004), fat (p = 0.001) intake and increased fiber consumption while GC reduced the fiber intake (p = 0.018). Glycemic control (MWG . 150 mg / dL) occurred in 75% of GI patients and in 31.6% of CG (p = 0.003), with negative correlation between changes in fiber intake and the MWG values (r = - 0.309 P = 0.035). The results were maintained after 12 weeks. Thus, individualized and appropriate nutritional intervention was more effective than conventional for fast glycemic control in patients with T2DM.

Avaliamos a importancia da orientacao nutricional, dentro de um conjunto de intervencoes multidisciplinares, em 47 pacientes diabeticos tipo 2 (DM2) hiperglicemicos (A1C . 8%), tratados de forma convencional (n=19;GC) ou intensiva em seis visitas semanais (n=28;GI) e avaliados pela glicemia media semanal (GMS) no inicio e apos 6 semanas. O GI reduziu o consumo de calorias (p= 0,001), de carboidratos (p= 0,004), de lipidios (p = 0,001) e aumentou o de fibras enquanto o GC reduziu o de fibras (p=0,018). Controle glicemico (GMS.150 mg/dL) ocorreu em 75% dos pacientes do GI e em 31,6% do GC (p = 0,003), havendo correlacao negativa entre as variacoes do consumo de fibras e a GMS (r = - 0,309; p = 0,035). Os resultados foram mantidos por 12 semanas. Assim, a intervencao nutricional individualizada e adequada mostrou-se mais eficaz que a convencional para a obtencao rapida do controle glicemico em pacientes com DM2.
