Objective: To determine the level of knowledge about gestational diabetes in pregnant patients at a secondary-level hospital.

Materials and Methods: This is an analytical, cross-sectional, observational study conducted with 374 pregnant women at the Regional General Hospital of Orizaba. They were administered an instrument measuring knowledge levels about risk factors and maternal-fetal complications of gestational diabetes. The study was carried out from February to September 2024. Descriptive statistics were used to obtain frequencies and percentages for qualitative variables, while quantitative variables were expressed through measures of central tendency. Inferential statistics were used to analyze the association between knowledge level and sociodemographic and/or clinical factors (age, marital status, education, occupation, locality, socioeconomic level, comorbidities, history of diabetes).

Results: A statistically significant association was found between knowledge level and factors such as education (p < 0.0001) and socioeconomic status (p < 0.0001), highlighting the importance of comprehensive nutritional care and education as key pillars in the prevention and treatment of gestational diabetes.
