Objective: To describe the situation of food insecurity of families according to the socioeconomic characteristics and dimensions of the food system in Brumadinho, state of Minas Gerais, Brazil, after the dam rupture in Córrego do Feijão mine. Methods: This is a descriptive study focused on households carried out from the baseline of the Brumadinho Health Project. Food insecurity, the main outcome, was assessed by the short version of the Brazilian Food Insecurity Scale. Other investigated variables were: socioeconomic data; geographic stratum of the households; family's assets; income; expenses; cultivation of food and animal husbandry for consumption. Descriptive analyses were performed comparing the food insecurity of the household according to the other variables by the χ2 test to compare the proportions. Results: Of the investigated households (n=1,441), 35.1% were facing food insecurity. facing food insecurity had: lower prevalence of masonry households with coating (91.4%; 95%CI 87.7%−94.1% vs. 96.7%; 95%CI 94.9%−97.8%); highest proportion of rudimentary cesspit (16.9%; 95%CI 13.3%−21.2% vs. 9.4%; 95%CI 7.4−11.9); lower prevalence of own and paid-off homes (63.9%; 95%CI 56.8−70.5 vs. 77.3%; 95%CI 72.3−81.7); and income reduction after the dam rupture (33.0%; 95%CI 27.1−39.6 vs. 14.1%; 95%CI 11.2−17.6), when compared with those in a food security situation. Conclusion: The prevalence of food insecurity was high, with report of a reduction in household income after the dam rupture. Moreover, most of the households had worse structural quality and sewage outfall. These results evidence the vulnerability of families and possible violation of the human right to adequate food, denoting the urgency of continuous reparative actions.

Background Disasters are events that bring with them effects that contribute to the disruption of the normality of a population and thus highlight the vulnerabilities of the health system. In Mariana and Brumadinho, the collapse of the dam of ore tailings brought with it several impacts that were felt in the short term and will be felt in the medium and long term. And that by being intensely intertwined with issues of economic and productive nature, has as its meaning an uninterrupted result of its activities. Methods Through the DATASUS database, two specific variables were chosen to perform the analysis: the approved amount and the approved value. For this research, a methodological device, the segmented regression line, was used to observe the influences that the disasters that occurred in Mariana and Brumadinho had on the ambulatory health systems. Results The results of the segmented regression line show that, with Mariana, the amount approved continued to grow throughout the period, which shows that there was no change because of the disaster. There was a reduction in spending. In Brumadinho, regarding the amount approved, there was an upward trend in the disaster’s month, which did not change immediately afterwards, and regarding expenditure, the growth pattern was maintained in all three periods. Corroborating this data, the relative and absolute base elements show an increase in the amount approved and in the number of services provided at various posts compared with Minas Gerais. Conclusions Based on the findings, it was possible to understand that although disasters exert an influence that may have some effect on the health system, the lack of significance sometimes cannot be interpreted as a lack of impact on the disaster. The segmented regression line outlines some effects that are not conclusive but indicative of a numerical interpretation and a trend interpretation.

Objective: In January 2019 a dam at the Córrego do Feijão mine suffered a catastrophic failure that killed 270 people and caused extensive damage. It is unknown how exposure to such a disaster might affect healthcare utilization. Methods: We assessed survey data from the Brumadinho Health Project, a cohort study that includes people who were exposed to the dam failure and two comparison groups: people unexposed to mining or the disaster and people from a mining community, but not exposed to the disaster. Main outcomes include any doctor visit or hospitalization in the past year, having a usual source of healthcare, having blood pressure and blood sugar checked, and being up to date with vaccinations, for adults 18 years and over. We used survey-weighted robust Poisson regression to assess differences between those exposed and the two comparison groups while controlling for confounders. Results: In multivariable models, the exposed group had a 15% higher chance of having a doctor visit than the unexposed group. For hospitalization and reports of blood pressure and blood sugar assessments, there was no significant difference among any of the groups. The exposed group had a 24% higher chance and the unexposed mining community had a 143% higher chance of being up to date with immunizations, as compared to the unexposed group. Conclusion: There were some differences in healthcare utilization among individuals exposed to the dam failure. Continued monitoring of the situation is warranted, as the full consequences of such a traumatic event may take considerable time to unfold.
