Diabetes in Pregnant Romanian Patients—Epidemiology and Prevention Strategies Proposal

Background/Objectives: Diabetes mellitus (DM) in pregnancy, including type 1 (T1DM), type 2 (T2DM), and gestational DM (GDM), represents an increasing health burden due to its maternal and fetal complications. Despite the increment in the global prevalence estimates of DM in pregnancy, in Romania, it has not been comprehensively described. This study aimed to analyze the prevalence and dynamics of DM in pregnancy in Romania between 2014 and 2024, using national databases, and to identify prevention strategies for reducing maternal and fetal complications. Methods: Data were obtained from the Romanian National Public Health Institute through two distinct sources: Database 1, consisting of reports from public and medical units associated with the National Health Insurance House and Database 2, based on the reports from general practitioners. Pregnancies complicated by DM were assessed by type, age group, and environmental settlement. Additional data were extracted on pregnancies with insufficient prenatal care and those of socially vulnerable individuals. Results: From 2014 to 2024, the prevalence of DM in pregnancy in Romania was consistently lower than European and global estimates, ranging from 1.01‰ to 3.08‰ in Database 1 and from 0.84‰ to 5.88‰ in Database 2, respectively. GDM accounted for the majority of cases, accounting for 65–88% of reported DM in pregnancy. The highest incidence was observed in the 20–39 years age group, with a growing proportion in women aged ≥40 years. Urban-rural disparities decreased over the decade, with rural cases reaching parity by 2024. Vulnerable populations included adolescents, women with insufficient prenatal care, and those with social risk factors, predominantly from rural areas. Conclusions: Although the reported prevalence of DM in pregnancy in Romania is lower than international figures, the true burden is likely underestimated. GDM remains the leading type of DM in pregnancy, mirroring global trends. Strengthening the reporting system, standardizing diagnostic criteria, and targeting high-risk groups through preconceptional counselling, lifestyle interventions, advanced monitoring technologies, and improving social support through the involved authorities are crucial steps to reduce maternal and fetal morbidity.
