Objective: To examine the effect of food insecurity on diet related pregnancy complications. Methods: The analysis included 777 Pregnancy, Infection and Nutrition study participants who completed the 18-item food security scale. Food secure status was categorized if all responses were negative; marginally food insecure if one or two affirmative responses; and food insecure if three or more affirmative responses. Gestational diabetes and anemia status were determined by chart review. Multinomial logistic regressions without and with backward elimination were employed. Results: Prevalence of marginal food insecurity and food insecurity were 8% and 5.5%. On average, women from marginally food insecure and food insecure households were younger and less educated, had a lower proportion being married, a greater number of children and a lower mean household income than food secure women. Restricting the sample to < 400% of poverty, women from food insecure and marginally food insecure households were at three fold greater risk of gaining excessive weight (AOR=3.4, 95% CI 1.2, 10.2) controlling for BMI, marital status, age, race and poverty, than food secure women. Race stratified analysis of the relationship between food security and gestational diabetes showed food insecure and marginally food insecure White women were at almost five times greater risk of gestational diabetes (AOR=4.9, 95% CI 1.2, 20.2) than food secure White women. This association, however, was not found for Black women (crude OR=0.76, 95% CI 0.14, 4.1). No association was found between food insecurity and anemia. Conclusion: Further investigation of the food insecurity-gestational diabetes association is needed.
