RESUMO
OBJETIVO:
Avaliar a orientação nutricional dentro de um conjunto de intervenções multidisciplinares. SUJEITOS EMÉTODOS:
Quarenta e sete pacientes diabéticos tipo 2, hiperglicêmicos, tratados de forma convencional (n = 19) ou intensiva (n = 28) e avaliados pela glicemia média semanal (GMS) no início e após 6 semanas.RESULTADOS:
GI reduziu o consumo de calorias (p = 0,001), carboidratos (p = 0,004), lipídios (p = 0,001) e aumentou o de fibras, enquanto o GC reduziu o consumo de fibras (p = 0,018). Controle glicêmico (GMS < 150 mg/dL) ocorreu em 75% do GI e, em 31,6% do GC (p = 0,003), houve correlação negativa entre as variações do consumo de fibras e a GMS (r =-0,309; p = 0,035). Os resultados mantiveram-se por 12 semanas.CONCLUSÃO:
A intervenção educacional intensiva de curto prazo mostrou-se mais eficaz que o tratamento convencional para a obtenção do controle glicêmico. Nossos resultados ainda indicam que um consumo mais adequado de fibras na alimentação contribui para a obtenção de um melhor controle da glicemia.ABSTRACT
OBJECTIVE:
To evaluate the importance of nutritional counseling within a set of multidisciplinary interventions. SUBJECTS ANDMETHODS:
Forty-seven patients with type 2 diabetes and hyperglycemia (A1C > 8%), treated conventionally (n = 19, GC) or intensively in six weekly visits (n = 28, GI) were analyzed. We evaluated mean weekly blood glucose (MWG) at baseline and after 6 weeks in both groups.RESULTS:
GI reduced caloric (p = 0.001), carbohydrate (p = 0.004), and fat (p = 0.001) intake, and increased fiber consumption, while GC reduced fiber intake (p = 0.018). Glycemic control (MWG < 150 mg/dL) occurred in 75% of GI patients and in 31.6% of CG patients (p = 0.003), with negative correlation between changes in fiber intake and MWG values (r =-0.309; P = 0.035). Results were maintained after 12 weeks.CONCLUSION:
Educational short-term intensive intervention was more effective than conventional treatment to achieve glycemic control. Our results also indicate that a more appropriate fiber content in the diet contributes for better blood glucose control in these patients.
