CONTEXTO E OBJETIVO: Deve-se diagnosticar o estado pré-diabético precocemente para evitar as complicações do diabetes mellitus (DM). Objetiva-se avaliar a prevalência de estado pré-diabético entre indivíduos sob risco de desenvolvimento de DM, buscando variáveis relacionadas à intolerância à glicose (IG) naqueles com glicemia de jejum (GJ) normal. TIPO DE ESTUDO E LOCAL: Estudo transversal no Hospital do Servidor Público Estadual, São Paulo. MÉTODOs: Analisou-se GJ e teste oral de tolerância a glicose (GTT), que determinaram a seguinte divisão: grupo 1 (GJ e GTT normais), grupo 2 (GJ normal e GTT alterado), grupo 3 (GJ alterada e GTT normal) e grupo 4 (GJ e GTT alterados). Determinou-se o perfil clínico, laboratorial e antropométrico dos indivíduos estudados. RESULTADOS: Estudaram-se 138 indivíduos: 44 no grupo 1, 11 no grupo 2, 33 no grupo 3 e 50 no grupo 4. A prevalência de estado pré-diabético foi 68,0%. Indivíduos do grupo 4, em relação ao grupo 1, demonstraram idade mais avançada [69,0 (55,5-74,0) versus 58,9 ± 11,8 anos, P < 0,05] e maior prevalência de condições de risco para o DM [5,0 (4,0-5,0) versus 4,0 (3,0-5,0), P < 0,05]. Dentre aqueles com GJ normal, 20,0% apresentaram IG. Nenhuma variável se correlacionou com o GTT. CONCLUSÃO: A prevalência de estado pré-diabético foi 68,0%; 20,0% daqueles com GJ normal apresentaram IG. Apesar de algumas variáveis clínicas, antropométricas e laboratoriais estarem descritas como relacionadas ao DM e ao estado pré-diabético, no presente estudo, nenhuma, à exceção do GTT, foi capaz de rastrear a presença de IG entre aqueles com GJ normal.
