Higher prenatal dietary glycemic index in the third trimester of pregnancy is associated with infant negative affect at 6 months.

The dietary glycemic index (GI) reflects post-prandial plasma glucose generation rate, with higher-GI foods rapidly increasing blood sugar. Prenatal consumption of high-GI foods is associated with offspring risk for obesity and metabolic disorders. The impact of prenatal dietary GI exposure on infant neurodevelopment remains unclear.

The association between food desert severity, socioeconomic status, and metabolic state during pregnancy in a prospective longitudinal cohort.

Poor metabolic health during pregnancy is associated with health concerns for pregnant individuals and their offspring. Lower socioeconomic status (SES) is one risk factor for poor metabolic health, and may be related to limited access to healthful and affordable foods (e.g.
