SUMMARY:

The intersectionality of race and gender highlights structural inequalities that amplify vulnerability to food insecurity, especially in marginalized populations. Beyond nutritional impacts, this condition is associated with negative sleep outcomes, emphasizing the need for analyses that consider the overlap of these social markers. Therefore, this study analyzed the association between food insecurity and sleep health, considering the intersectionality of race/color and gender. This is a population-based cross-sectional study of adults and elderly residents of Natal/RN, between 2019 and 2020. This work is a segment of the larger project “Brazilian Usual Consumption Assessment - Brazuca Natal”. Food insecurity was assessed using the Brazilian Food Insecurity Scale (EBIA), and sleep information was evaluated by duration and self-reported sleep satisfaction. Analyses included descriptive statistics and Poisson regression with robust variance. It was observed that Black women presented the highest prevalence of food insecurity, showing a 94% higher prevalence of food insecurity compared to white men (PR = 1.94; 95% CI: 1.12–3.36; p = 0.017). Sleep dissatisfaction also maintained a significant association with food insecurity: very dissatisfied or dissatisfied individuals presented a 53% higher prevalence of food insecurity (PR = 1.53; 95% CI: 1.24–1.89; p < 0.001). Furthermore, long sleep duration remained associated with food insecurity, indicating a 33% higher prevalence of food insecurity among those who slept more than 9 hours (PR = 1.33; 95% CI: 1.03–1.73; p = 0.028), even after adjusting for sociodemographic variables. These findings reinforce the idea that the overlap of racism and sexism can intensify vulnerabilities that compromise both access to food and sleep health.
