Background Heat exposure, which will increase with global warming, has been linked to increased risk of a range of types of cause-specific hospitalizations. However, little is known about socioeconomic disparities in vulnerability to heat. We aimed to evaluate whether there were socioeconomic disparities in vulnerability to heat-related all-cause and cause-specific hospitalization among Brazilian cities.

“…S1), with small thermal amplitudes, there was no association between temperature and mortality due to AMI, either for cold or hot temperatures (Table 2). A study recently published investigated the relationship between temperature and hospitalizations, finding a positive association with all-cause admissions in all Brazilian regions, but minimal association with cardiovascular causes 23 . Two studies conducted in Vietnam, an equatorial and tropical climate country, presented conflicting results.…”

Ambient temperature may lead to decompensation of cardiovascular diseases and deaths by acute myocardial infarction (AMI). Little is known about this relationship in South American countries located in regions of a hot climate. This study aims to investigate the effects of ambient temperature on mortality due to AMI in six Brazilian micro-regions, which present different climates. We analyzed daily records of deaths by AMI between 1996 and 2013. We estimated the accumulate relative and attributable risks with lags of up to 14 days, using distributed non-linear lag model. Micro-regions that were closest to the equator did not show an association between temperature and mortality. The lowest risk temperatures varied between 22 °C and 28 °C, in the Southern region of Brazil and the Midwest region, respectively. Low temperatures associated with the highest mortality risk were observed in the same areas, varying between 5 °C and 15 °C. The number of deaths attributed to cold temperatures varied from 176/year in Brasilia to 661/year in São Paulo and those deaths attributed to hot temperatures in Rio de Janeiro amounted to 115/year. We showed the relative risk and the attributable risk of warmer and colder days in tropical regions. The estimate of the number of deaths due to climate, varying according to each area, is a way of bringing information to those responsible for health policies based on easily-understood measurements.

“…During the study period (2009-2018), 329,329 respiratory disease hospitalizations were recorded in the SUS database, which amounted to US $117.273 million. Both the number of hospitalizations and their costs decreased as the amount of rainfall increased, probably owing to the rainfall improving air quality, as reported by Locosseli et al [64], Sera et al [65] and Zhao et al [66]. According to Duhanyan and Roustan [70], Xu et al [71] and Zhao et al [63], the pollutants, gases, and PM are removed from air by below-cloud wet scavenging and precipitating inside the raindrops.…”

“…The following hypothesis was verified: The PM 2.5 , PM 10 , O 3 , NO 2 , SO 2 , and CO emitted by several air sources in São Paulo city contribute to the increased respiratory disease hospitalizations and their costs. Rain is known to decrease air pollution, and therefore, the effect of rainfall was also analyzed to determine whether it was correlated with the decrease in respiratory disease hospitalizations and their costs [40,43,[63][64][65][66]. If an inverse relationship with the amount of rainfall could be confirmed, then the harmful effects of PM 2.5 , PM 10 , O 3 , NO 2 , SO 2 , and CO should increase in the absence of rainfall [16][17][18]21].…”

Clean Production of Biofuel from Waste Cooking Oil to Reduce Emissions, Fuel Cost, and Respiratory Disease Hospitalizations

et al. 2021

Renewable energies are cleaner forms of energy, and their use, has intensified in recent decades. Thus, this work presents a proposal for reducing the emissions, fuel cost, and respiratory disease hospitalizations using environmental cost accounting principles to produce biodiesel production from waste frying oil. In our methodology, we conducted surveys, and collected waste cooking oil samples from local households and restaurants in São Paulo city, Brazil. Then, we produced biodiesel using these samples. Data on air pollutants were collected and correlated with the number of hospitalizations for respiratory diseases and their costs. Our results indicate that 330,000 respiratory disease hospitalizations were recorded in São Paulo city between 2009 and 2018, and the total cost for the Brazilian government reached US $117 million. Improving the city air quality by switching from fossil fuels to biodiesel could reduce the annual number of hospitalizations to 9880 and cost US $3.518 million, because the amount of pollutants emitted from burning fossil fuels was positively correlated with the number of respiratory disease hospitalizations and their costs. Moreover, the emission rates of particulate matter with particles less than 10 and 2.5 µm in diameter exceeded the World Health Organization limits throughout the study period. Using the survey data, we estimated that the average monthly quantity of waste cooking oil was 9794.6 m3, which could generate 9191.2 m3 of biodiesel and produce 239,713 t CO2 of carbon credits. Environmental cost accounting revealed that it would be possible to achieve an annual profit of approximately US $300 million from the sale of excess biodiesel, carbon credits, and glycerine, and fuel acquisition savings which could improve the image of São Paulo city and quality of life of its residents. Thus, we present this as a way to reduce cost and hospitalizations, and increase the number of available hospital beds for other diseases, such as COVID-19.
