Aim:
To describe the annual incidence of gestational diabetes mellitus (GDM) among women beneficiaries of the Mexican Institute of Social Security (IMSS) in Mexico from 2008-2023.
Methods:
Data from the IMSS's Institutional Automated System for Epidemiological Surveillance (SIAVE) from 2008-2023 were used. GDM cases during pregnancy were identified using ICD-10 O24.4 diagnostic codes. Changes in annual incidence were evaluated using the Join-Point program version 5.1.0 to calculate the annual percentage change (APC) and the average annual percentage change (AAPC).
Results:
A total of 103,749 cases of diabetes during pregnancy were recorded and the annual incidence rate of GDM increased over the time. The incidence of GDM peaked in 2021 among those 19 years old or younger, and in 2022 among those 20 years old or older, with a higher incidence in the latter group. There was a considerably higher incidence of GDM in the North region compared to the other regions. The estimated AAPC for the 2008-2023 period was 21.1 (16.8-25.6) per 1000 live births, and was higher in the West region.
Conclusions:
This study demonstrates a nationwide substantial upward trend in GDM incidence between 2008 and 2023. Both teenage and adult women reported a higher incidence in recent years (2021 and 2022, respectively). The North region had the highest incidence, while the West had the highest AAPC.

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
