Objective To examine the longitudinal relations among household food security status, maternal depressive symptoms and maternal BMI. Methods The Early Childhood Longitudinal Study–Birth Cohort (ECLS‐B) is a nationally representative sample of approximately 10,700 families, evaluated at 9m, 2, 4, and 5 yrs. Maternal BMI (measured), depressive symptoms (CES‐D 12‐item scale); and food security status (USDA 18‐item scale) were collected between 2001–2006. We applied a mixed effect model to examine weighted (adjusting for sampling design and non‐response) relations between baseline maternal depressive symptoms, household food security status (ever vs. never; across time points), and maternal BMI (yrs 2, 4, and 5). Results At baseline (9m), 13% of mothers reported moderate/severe depressive symptoms (CES‐D ≥12); 26% reported food insecurity at least once. Mean maternal BMI ranged from 22.9 at 9m to 23.8 at 5 yrs; 39% were overweight (BMI ≥ 25) by 5 yrs. In a model controlling for race/ethnicity and poverty level, mothers with ≥ 1 food insecurity report had a mean BMI 0.88 points higher at each time point than mothers with no food insecurity reports ( p <0.001); mothers reporting baseline moderate/severe depressive symptoms had a marginally higher yearly BMI increase (0.08 BMI/yr, p =0.08) than mothers with mild/no symptoms. Conclusion Moderate/severe depressive symptoms at 9 m have a marginal effect on yearly maternal BMI increase. A single incidence of household food insecurity during early parenting is associated with higher maternal BMI.
