Prevalence of diabetes and glycemic control in Mexico: national results from 2018 and 2020

Abstract

Objective. To estimate the prevalence of diabetes (diag-nosed and undiagnosed), glycemic control in Mexico, and its associated factors. Materials and methods. We used data from Ensanut 2018 (n=12 648) and 2020 (n=2 309). We defined diabetes as fasting glucose ≥126 mg/dl or HbA1c≥6.5% or previously diagnosed; glycemic control was defined as HbA1c<7%. We fitted Poisson regression models to assess the association between diabetes, glycemic control, and potential associated factors. Results. The total prevalence of diabetes was 16.8% in 2018 and 15.7% in 2020. In 2018, 38% of adults with diabetes were unaware of their disease, while in 2020 this figure was 29%. Glycemic control was observed in 42% of participants in 2018 and 39% in 2020. Longer disease duration was associated with lower glycemic control, while older age, having a diet, and being affiliated to IMSS, Pemex, Sedena, or private healthcare were associated with better control. Conclusion. Mexico is among the countries with the highest diabetes prevalence. A high proportion of adults with diabetes did not have a previous diagnosis, and the proportion with glycemic control is low. Strengthening screening to achieve a timely diagnosis, and improving glycemic control, should be key actions in the management of diabetes
