چکیده مقاله
Background Gestational diabetes mellitus GDM is a common pregnancy complication characterized by glucose intolerance with onset or first recognition during pregnancy It poses significant risks to both maternal and fetal health, including preeclampsia, macrosomia, and future development of type 2 diabetes Simultaneously, food insecurity—defined as limited or uncertain access to adequate and nutritious food—affects millions of households globally and disproportionately impacts vulnerable populations, including pregnant women Materials and Methods This review was based on an extensive literature search across leading scientific databases such as PubMed and Scopus, Web of Science, and Google Scholar Peer reviewed articles, systematic reviews, meta analyses, and studies examining food insecurity in relation to GDM risk, management, or outcomes from 2015 to 2025 were included Keywords used in this search included combinations of Gestational diabetes mellitus GDM , Food insecurity , Maternal nutrition , Pregnancy outcomes , Prenatal care , Nutritional interventions and Type 2 diabetes risk” After searching with the selected keywords, 38 related articles were identified, of which 10 were ultimately included in the review Objectives of research The objective of this review is to explore and synthesize existing literature on the relationship between food insecurity and gestational diabetes mellitus GDM , with a focus on identifying key mechanisms, risk factors, and public health implications Key Themes and Findings Nutritional Quality and Dietary Patterns: Food insecurity often leads to consumption of inexpensive, calorie dense, nutrient poor foods Pregnant women in food insecure households may struggle to meet dietary guidelines, increasing the risk of insulin resistance and poor glycemic control Limited access to fresh produce and whole grains contributes to suboptimal gestational weight gain GWG , which is a known risk factor for GDM Gestational Weight Gain GWG and GDM Risk: Both inadequate and excessive GWG are associated with higher GDM risk Food insecurity can disrupt healthy weight gain due to erratic eating patterns, binge eating when food is available, or chronic undernutrition Studies show that women with food insecurity are more likely to fall outside recommended GWG ranges, compounding their risk for GDM Psychosocial Stress and Metabolic Health: Chronic stress from food insecurity activates the hypothalamic pituitary adrenal HPA axis, increasing cortisol levels Elevated cortisol impairs insulin sensitivity and glucose metabolism, biologically linking stress to GDM development Psychological distress also affects health behaviors, including medication adherence, physical activity, and dietary choices Healthcare Access and Utilization: Food insecure women may delay or avoid prenatal care due to financial constraints, transportation barriers, or competing priorities Reduced access to diabetes screening, nutritional counseling, and follow up care limits early detection and management of GDM Language barriers and lack of culturally appropriate resources further hinder effective care in marginalized communities Disparities and Social Determinants: GDM and food insecurity disproportionately affect racial and ethnic minorities, low income households, and single parent families Structural inequities—such as neighborhood food deserts, systemic racism, and underfunded healthcare systems—amplify these risks Addressing social determinants of health is critical to reducing disparities in GDM outcomes Maternal and Neonatal Outcomes: Food insecure women with GDM face higher risks of preterm birth, cesarean delivery, and NICU admissions Poor glycemic control during pregnancy can lead to fetal macrosomia, birth trauma, and long term metabolic disorders in offspring Postpartum, these women are also more likely to develop type 2 diabetes and experience continued food insecurity On the other hand, the idea that prenatal food insecurity increases the risk of depression and anxiety during pregnancy and postpartum is well supported by research Policy and Programmatic Implications: Integrating food insecurity screening into prenatal care can identify at risk women early Programs like WIC and SNAP, when tailored to pregnant women's needs, can improve dietary quality and reduce GDM risk Community based interventions—such as mobile food markets, culturally tailored nutrition education, and food pharmacies—show promise in improving outcomes Implications for Practice and Policy Integrating food insecurity screening into prenatal care can help identify at risk individuals early Providing access to healthy foods, nutrition education, and support services may reduce GDM incidence and improve outcomes Policymakers should consider expanding food assistance programs and tailoring them to meet the specific needs of pregnant women Conclusion Food insecurity is a significant and modifiable risk factor for gestational diabetes Addressing it through comprehensive public health strategies and prenatal care reforms could reduce the burden of GDM and promote healthier pregnancies
