Food insecurity, the limited access to sufficient healthy food for a healthy life, is a significant driver of poor health for millions of people globally, including in high income countries. Food insecurity is associated with adverse impacts on diet quality, mental health, and increased risk of chronic conditions. As a recognised ‘social determinant of health’, food insecurity undermines the physical and mental wellbeing of individuals across all life stages. Pregnancy is a life stage particularly important in which to consider the short- and long-term impacts of food insecurity, as optimal antenatal nutrition is associated with best outcomes for the mother and offspring. This presentation will outline current evidence regarding the health consequences of food insecurity during pregnancy, including for women with diabetes, and recommend actions within the clinical setting to identify and address this under-estimated public health concern.
