Racism and food insecurity: misfortunes of a Quilombola community in the Brazilian Legal Amazon

This study examined food insecurity in the Quilombola community of Imbiral Cabeça-Branca, in Maranhão, Brazil, during the COVID-19 pandemic. A cross-sectional study was conducted in the last quarter of 2021 with 25 household heads from the community. Most participants were women (52.0%) with low schooling and were unemployed (68.0%), and 76.0% received a Federal Emergency Aid. The mean household density was four people, and houses were predominantly made of rammed earth, lacking basic sanitation. The consumed water came from artesian wells, and most houses had electricity. Food insecurity was identified in all households, with 12.0% classified as mild, 24.0% as moderate, and 64.0% as severe. The severe form was more common in households headed by single men (75%), older adults, less-educated individuals (78.7%), and the unemployed (64.7%). Food insecurity in the Quilombola community and other similar communities in the country results from substandard living conditions, unemployment, food deprivation, and lack of land titling. These factors also contribute to the perpetuation of institutional and environmental racism faced by these communities.

Comparison of beriberi cases in indigenous and non-indigenous people, Brazil, 2013 to 2018

Beriberi is the clinical manifestation of severe and prolonged thiamine (vitamin B1) deficiency. It is a neglected disease that affects low-income populations facing food and nutrition insecurity. The aim of this study was to compare cases of beriberi among indigenous and non-indigenous people in Brazil. We conducted a cross-sectional study using data on cases of beriberi during the period July 2013-September 2018 derived from beriberi notification forms available on the FormSUS platform. Cases in indigenous and non-indigenous patients were compared using the chi-squared test or Fisher's exact test, adopting a significance level of 0.05. A total of 414 cases of beriberi were reported in the country during the study period, 210 of which (50.7%) were among indigenous people. Alcohol consumption was reported by 58.1% of the indigenous patients and 71.6% of the non-indigenous patients (p = 0.004); 71.0% of the indigenous patients reported that they consumed caxiri, a traditional alcoholic drink. Daily physical exertion was reported by 76.1% of the indigenous patients and 40.2% of the non-indigenous patients (p < 0.001). It is concluded that beriberi disproportionately affects indigenous people and is associated with alcohol consumption and physical exertion.

Racial and regional inequality in the temporal trend of stunting and excess weight in Brazilian children under five years of age

OBJECTIVE

To analyze the occurrence of racial and regional inequality in the temporal trend of the prevalence of stunting and overweight in Brazilian children under five years of age over the years 2008-2018.

METHODS

An ecological time-series study with data from the Food and Nutrition Surveillance System on the prevalence of stunting and overweight in children under five years old according to race/skin color, region, and year. To assess differences between median prevalence per year of outcomes, the Kruskal-Wallis test was performed. Linear regression analyses were proposed to assess trends in the prevalence of outcomes over the years.

RESULTS

In Brazil, black children tended to be overweight (β=4.611; p=0.042). Among black children, there was an increase over the years in stunting in the Southeast (β=3.960; p=0.014) and a decrease in the South (β=-4.654; p=0.022). In Brazil and in most regions, the median prevalence of stunting was higher in black children than in white ones (12.86 vs. 11.54%, p<0.001). In the Southeast and South, black children also had the highest prevalence of overweight (15.48 and 15.99%, respectively).

CONCLUSION

Children from less developed regions of Brazil and of black skin color/race were more vulnerable to a double burden of malnutrition.

Beriberi in Brazil: A Disease That Affects Indigenous People

BACKGROUND

Beriberi is the clinical manifestation of thiamine deficiency. It is multicausal and typically associated with poverty and food insecurity among vulnerable populations, such as indigenous people.

OBJECTIVE

The objective of this study was to carry out a spatial analysis of reported cases of beriberi among indigenous people in Brazil.

METHODS

Cross-sectional study using time series data on suspected cases of beriberi reported to the Ministry of Health via the FormSUS between July 2013 and September 2018. Indigenous villages were georeferenced, and Kernel density estimation was used to identify patterns of the spatial distribution of beriberi cases.

RESULTS

A total of 414 cases of beriberi were reported in the country of which 210 (50.7%) were indigenous people. All the cases in indigenous people occurred in states located in the Legal Amazon (Maranhão, Roraima, and Tocantins). Kernel density estimation showed high-density areas in Tocantins and Roraima.

CONCLUSIONS

This is the first nationwide study of reported cases of beriberi. The findings can be used to guide actions that contribute to the monitoring and prevention of beriberi among indigenous people.

Malnutrition and associated factors among quilombola children under 60 months of age in two cities of the state of Maranhão, Brazil

OBJECTIVE

To evaluate the prevalence of malnutrition in children under 60 months of age living in quilombo remnant communities of two municipalities in the state of Maranhão and their associated factors.

METHODS

This is a cross-sectional study conducted with a sample of 372 children in August 2015. Socioeconomic, demographic, maternal and child information were collected. The anthropometry followed the one proposed by the World Health Organization. Height-for-age and weight-for-height rates were calculated using Anthro software version 3.2.2. Poisson regression was performed with a robust variance for the association of malnutrition with the studied variables, using Stata software version 14.0.

RESULTS

Child malnutrition was high for height-for-age (15.1%) and weight-for-height (7%). Children whose mothers had a short height (< 1.497 m) were more likely to have height-for-age deficits (p < 0.05). No variables were statistically associated with low weight-for-height.

CONCLUSION

Child malnutrition persists as a public health problem in vulnerable regions, and maternal factors such as low maternal height may explain the short stature of the children. The need for actions to address this nutritional deviation is pointed out.
