OBJECTIVE: To examine how race, income and food insecurity (FI) interact during pregnancy and whether FI contributes to disparities in maternal and infant health outcomes.
DESIGN: Observational cohort study employed sequential explanatory a mixed-methods design, with a survey phase (including Household Food Security Survey Module [HFSSM] six-item) and medical record abstraction followed by semi-structured interviews.
SETTING: Online survey, virtual interviews.
PARTICIPANTS: The participants were individuals who gave birth in Louisiana, USA, between June 2020 and June 2021. The quantitative phase comprised 1691 individuals who completed the survey. A nested cohort of forty individuals (evenly split by race (Black v. White) and income (low v. high)) subsequently completed semi-structured interviews.
RESULTS: Race and income were independently associated with both FI and maternal and infant health outcomes. When considering both income and FI, low-income individuals with FI were 1·73 times more likely to deliver low birthweight (LBW) infants (adjusted Odds Ratio [aOR] 95 % CI: 1·07, 2·82) and 1·43 times more likely to experience adverse infant outcomes (aOR 95 % CI: 1·02, 2·00) than high-income individuals without FI. Black individuals with FI were 2·49 times more likely to deliver LBW infants (aOR 95 % CI: 1·45, 4·29) than White individuals without FI. Interview findings revealed low-income individuals faced disproportionate barriers to accessing healthy food and making dietary choices, which were further complicated by pregnancy-related conditions.
CONCLUSIONS: The interplay between race, income and FI significantly increases the risk of adverse infant health outcomes, demonstrating a synergistic effect. Targeted efforts to address FI, particularly among low-income pregnant individuals, are essential to improving maternal and infant health outcomes.
