RESUMO
This study aims to assess the association between economic class, race/skin color, and food consumption among Brazilian college students. A cross-sectional web-based survey was conducted with college students from all over Brazil. Demographic data, economic class, self-reported race/skin color, anthropometry, and food consumption markers from the Brazilian Food and Nutrition Surveillance System were collected. The final sample comprised 5843 participants with a mean age of 24.1 (SD: 6.3) years, 4292 (73.5%) were female, and 810 (13.9%) in the highest economic stratum. We observed a progressive decrease in the frequency of fresh fruits and vegetables consumption from higher to lower economic classes (p < 0.01 for both). Contrarily, there was a progressive increase in the frequency of consumption of beans from higher to lower economic classes (p < 0.01). The frequency consumption of vegetables was also associated with race/skin color (p < 0.01), being lower in brown (PR: 0.94; CI 95%: 0.90; 0.98), and black (PR: 0.91; 95% CI: 0.85; 0.98) individuals, compared to white individuals. Brown individuals showed higher frequency consumption of beans (PR: 1.10; 95% CI: 1.05; 1.15) than whites. When compared to individuals of white race/skin color, brown (PR: 1.07; 95% CI: 1.01; 1.13) and black (PR: 1.15; 95% CI: 1.07; 1.23) individuals showed higher frequency consumption of sweetened beverages. Economic class and race/skin color were independent factors associated with the food consumption of Brazilian college students.

BACKGROUND: Iron deficiency anemia (IDA) is among the most common micronutrient deficiencies in women of childbearing age and may affect children's development. Brazil has several national programs to tackle this condition, such as food fortification and supplementation for pregnant women, but IDA prevalence in this population has not been systematically reviewed. We sought to determine the prevalence of IDA in Brazilian women of childbearing age through a systematic review with metanalysis. METHODOLOGY: A protocol was previously published on the PROSPERO platform under the code CRD42020200960. A panel of the National Council for Scientific and Technological Development (CNPq) approved the protocol of this study under the public call number 26/2019. The main databases searched were MEDLINE, Web of Science, Scopus, Lilacs, and SciELO. In gray literature, the Brazilian Digital Library of Theses and Dissertations and the annals of the Brazilian Congress of Epidemiology and the Brazilian Congress of Public Health were accessed. The search strategy involved terms related to the condition (IDA) and the age group of the population of interest (teenagers and adults). Studies that had assessed the prevalence of IDA in Brazilian women of childbearing age (10-49 years) were included. Three independent reviewers read all titles and abstracts and extracted data from the included studies. Random effects meta-analyses using the Freeman-Tukey arcsine transformation were carried out with prevalence data, and meta-regression was conducted to test for subgroup differences. The quality of the studies was assessed using the Newcastle-Ottawa Scale. RESULTS: From 21,210 unique records screened, 237 full-texts were retrieved, of which 91 were included in the qualitative synthesis, and 83 were included in the meta-analysis. The overall IDA prevalence was 25% (95% CI [23-28], 83 studies). The subgroup of studies that used random sampling showed a prevalence of 22% (95% CI [17-27], 22 studies), whereas in those with non-random sampling, the prevalence was 27% (95% CI [23-30], 61 studies), without significant differences between subgroups in the metaregression (P = 0.13). High prevalence of IDA were found in the subgroups of studies conducted in the North and Northeast regions (30%; 95% CI [24-37]; seven studies, and 30%; 95% CI [26-34]; 27 studies, respectively), in studies conducted with indigenous population (53%; 95% CI [27-78], four studies), and with studies that had their collections after 2015 (28%; 95% CI [23-34], nine studies). CONCLUSIONS: IDA in women of childbearing age remains a public health problem in Brazil, especially in the North and Northeast region. The national programs should be strengthened and more thoroughly supervised to decrease this condition nationally.

The study's objective was to determine the prevalence of food addiction (FA) in Brazilian university students and to verify whether there is an association with anxiety, depression, and adherence to the social distancing measures adopted during the COVID-19 pandemic. This is a nationwide cross-sectional study carried out through the application of online questionnaires. Self-reported data on age, sex, economic class, race/skin color, anthropometric data, depression diagnosis, anxiety, modified Yale Food Addiction Scale 2.0 (mYFAS 2.0), and adherence to social distancing measures were collected. 5368 participants were included, with a mean age was 24.1 ± 6.3 years, the majority were female (n = 3990; 74.3%), and the mean BMI in our sample was 24.5 ± 5.3 kg/m2. The prevalence of FA was 19.1% (95%CI: 18.0; 20.0%). An association was observed between FA with depression (PR: 1.60; 95%CI: 1.43; 1.78; p < 0.01), and anxiety (3.13; 95%CI: 2.74; 3.58; p < 0.01), but not with adherence to social distancing measures (p = 0.70). In conclusion, there was a higher prevalence of FA in Brazilian university students. Besides, university students with anxiety, depression, overweight, or obesity and females are more prone to FA.Level of evidence Level V, Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

There is evidence that during the COVID-19 pandemic, there was an increase in anxiety and depression rates among college students. However, little is known about how generalized anxiety disorder (GAD) developed among individuals of different race/skin color. This study aimed to determine whether there are racial differences in GAD in Brazilian university students during the COVID-19 pandemic. This is a nationwide cross-sectional study, carried out through the application of online questionnaires to university students from 94 Brazilian universities. Self-reported data on age, sex, economic class, race/skin color, anthropometric data, and adherence to social distancing measures were collected. To determine the GAD, the Generalized Anxiety Disorder 7-item scale was applied. A total of 5879 participants were included, with a mean age of 24.1 ± 6.4 years, and the majority were female (n = 4324, 73.5%), most self-declared to be whites (n = 2945, 50.1%), followed by browns (n = 2185, 37.2%) and blacks (n = 749, 12.7%). The prevalence of GAD among black Brazilian university students (47.3% [95% CI 43.7, 50.8]) was significantly higher than that of browns (38.6% [95% CI 36.6, 40.7]) and whites (44.1% [95% CI 42.3, 45.9]), even after multivariable adjustment by other sociodemographic factors. The findings of the present study suggest a possible racial difference in GAD among Brazilian university students, in which those who declared their race/skin color as black showed a greater risk for GAD than those who declared themselves as white or brown.
