Lazo‐Porras M, Ruiz‐Alejos A, Miranda JJ, et al. - This PERU MIGRANT Study was undertaken to determine if intermediate hyperglycaemia, defined by fasting plasma glucose and HbA_1c criteria, was correlated with mortality in a 10‐year cohort of people in a Latin American country. This investigation was performed in three different population groups (rural, rural‐to‐urban migrant, and urban). The authors divided the study cohort into population groups as follows: 207 people in the rural population group, 583 in the rural‐to‐urban migrant group and 198 in the urban population group. The prevalence of intermediate hyperglycaemia according to the American Diabetes Association impaired fasting glucose definition, the International Expert Committee HbA_1c‐based definition and the American Diabetes Association HbA_1c‐based definition was 6%, 12.9% and 38.5%, respectively. Data reported that the mortality rate after 10 years was 63/976 (7%). In a cohort from Peru after 10 years, intermediate hyperglycaemia defined using the American Diabetes Association HbA_1c criteria has been linked to an elevated mortality rate. HbA_1c appears to be a mortality-related factor in this Peruvian population.
