Rationale: A modified Mediterranean diet (MMD) may improve metabolic outcomes in gestational diabetes (GDM), yet little is known about the clinical and sociocultural factors that influence adherence during pregnancy
Methods: Observational, retrospective and prospective study including 68 women diagnosed with GDM (NDDG 1979 criteria) attending an endocrinology clinic from Oct 2018 to Jan 2025. Adherence to the MMD was assessed using the PREDIMED questionnaire (alcohol item excluded), before and after nutritional education. Women were grouped by post-intervention adherence (≤6 vs. ≥7 points).
Results: Median age was 37 years; 50% had pregestational obesity and 23.5% belonged to a high-risk ethnic group. Adherence significantly improved after education (median 6 vs. 8; p < 0.001, Wilcoxon test). Etnicity was independently associated with low adherence (OR 0.083; p = 0.049). No significant differences in glucose values (SOG test), insulin dose or time to glycaemic targets were found between adherence groups (p > 0.05). Likewise, obstetric outcomes such as delivery week and neonatal weight did not differ significantly. Maternal complications were more frequent in the low adherence group (14.6% vs. 0%) but without statistical significance.
Conclusion: A structured nutritional education program improved adherence to the MMD in women with GDM. Belonging to a high-risk ethnic group was independently associated with poorer adherence, highlighting the need for tailored interventions. No differences were observed in metabolic or obstetric outcomes based on dietary adherence in this cohort.
