Educational inequality in consumption of in natura or minimally processed foods and ultra-processed foods: The intersection between sex and race/skin color in Brazil.

Background: It remains uncertain how the intersection between educational, gender, and race/skin color inequalities influences food consumption in Brazil. In this study, we examined the educational inequality in the consumption of in natura/minimally processed and ultra-processed foods by Brazilians with an intersectional perspective between sex and race/color. Methods: We used cross-sectional data from the Telephone Surveillance System (VIGITEL 2019), comprising 52,443 participants ≥ 18 years. Daily food consumption was considered high when consumption of ≥5 foods for each food group was reported the day before the survey. Educational inequality in food consumption was assessed by the slope index of inequality (SII) and the relative index of inequality (RII) according to sex and race/color (White; Black/Brown). Positive SII and RII values > 1.0 indicate higher food consumption among more educated participants. Results: The consumptions of in natura/minimally processed and ultra-processed foods were more prevalent in those with the highest level of education (≥12 years) and intermediate education (9-11 years), respectively. However, highly educated White women had higher consumption of in natura/minimally processed foods than Black women with the same education level, and White men in low and intermediate school levels had higher consumption of these foods than Black men with the same education levels. We found higher absolute educational inequality for in natura/minimally processed foods among White women (SII 21.8, 95% CI 15.3, 28.4) and Black/Brown men (SII 19.3, 95% CI 12.5, 26.1). Black/Brown men (SII 7.3, 95% CI 0.5, 14.0) and Black/Brown women (SII 5.6, 95% CI 1.0, 10.2) had higher absolute educational inequality than White men (SII -3.3, 95% CI -10.9, 4.3; P = 0.04) in the consumption of ultra-processed foods. Conclusion: Educational inequalities influenced the consumption of in natura/minimally processed more than ultra-processed foods, and, for the latter, inequalities were greater among Black/Brown men and women than among White men.

Social inequality in food consumption between 2008 and 2019 in Brazil.

OBJECTIVE: To analyse the trend of social inequality in food consumption among Brazilians from 2008 to 2019. DESIGN: Time series analyses using cross-sectional annual data from the Telephone Surveillance System (VIGITEL 2008-2019). Food consumption was evaluated through: (1) consumption of five or more portions of fruits and vegetables in ≥5 d/week; (2) consumption of beans in ≥5 d/week and (3) consumption of soft drinks or artificial juices in ≥5 d/week. Absolute inequality was assessed by the slope index of inequality (SII) and relative inequality by the concentration index (CIX). SII and CIX positive values indicate higher prevalence among more educated citizens and negative among less educated ones. Time trend was assessed by linear regression using weighted least squares. SETTING: 26 Brazilian state capitals and the Federal District. PARTICIPANTS: 621 689 individuals ≥18 years. RESULTS: Fruits and vegetable consumption was more prevalent among the more educated citizens, while beans were mostly consumed by the less educated, and soft drinks or artificial juices was more prevalent among individuals with intermediate education. The highest absolute inequality was found for beans (SII2019 -25·9). In 12 years, the absolute inequality increased for fruit and vegetable consumption (from SII2008 12·8 to SII2019 16·2), remained for beans (SII2008 -23·1 to SII2019 -25·9) and reduced for soft drinks or artificial juices (SII2008 8·7 to SII2019 0·4). Relative inequality was low and constant. CONCLUSION: Despite the advances reducing inequalities in soft drinks or artificial juice consumption, the increase in the social gap for adequate consumption of fruits and vegetables is troublesome.
