Food consumption in Brazil: an intersectional analysis of Vigitel 2023 data
摘要
The aim of this study was to assess the food consumption of the Brazilian population through the lens of the intersectionality between sex and race/skin color. This is a cross-sectional study using data from the 2023 Vigitel survey, involving adults aged 18 years and older. Food consumption was measured using a score based on the intake on the previous day of 12 unprocessed/minimally processed foods (UN/MP) and 12 ultra-processed foods (UPF), classified according to the degree of industrial processing. The score ranged from 0 (higher UN/MP and lower UPF consumption) to 24 points (lower UN/MP and higher UPF consumption). The score was then categorized into “higher-quality diet” (below the 75th percentile) and “lower-quality diet” (at or above the 75th percentile). Intersectionality was analyzed by combining the variables sex (male, female) and race/skin color (White, Black—including Black and Brown individuals), resulting in four groups: White men, Black men, White women, and Black women. Data analysis included Pearson’s chi-square test and simple and multiple logistic regression, adjusted for age, education level, and marital status (p < 0.05). The sample included 21,690 adults. In the adjusted analysis, Black women were found to be 29% more likely (OR: 1.29; 95% CI: 1.06–1.45) to have a lower-quality diet compared to White men. The study results reveal poorer diet quality among self-identified Black individuals, especially women, characterized by a lower-quality dietary pattern.
