“…This tendency is in agreement with observations of a previous study of Sao Paulo and the most recent study of Rio Grande do Sul, as well as with the tendency of COPD deaths for people over 35 years old (11)(12)(13)18). The decline of asthma mortality may be explained by the following factors, 1980198119821983198419851986198719881989199019911992199419951996Year 19971998 alone or in combination: an artifact of health statistics, a decline of asthma prevalence, and a reduction of casefatality rates.…”

“…Another study investigated asthma mortality in the southern state of Rio Grande do Sul, and reported an increase of asthma death rates between 1970 and 1992, only for people aged 5-19 years old (12). Later, the same authors published a reappraisal of these data along with new data, from 1981 to 2003 in Rio Grande do Sul, which showed a decline of death rates since the late 1990s (13).…”

“…In parallel with the high prevalence of asthma, there is evidence for rising trends in asthma mortality in some Latin American countries. In Brazil, mortality rates rose in the 5–19 year age group over the period 1970 to 1992 and this age group had the highest asthma mortality (14), although later studies indicate that mortality rates in Southern Brazil peaked in the mid nineties and have declined since (25). Official health statistics in Brazil estimated a mortality rate from asthma of 1.5 deaths per 1000 inhabitants during the 1990s (14) that is between two and 10 times greater than that reported in the developed world (26).…”

Asthma has emerged as an important public health problem in many Latin American countries over the past decade. In Brazil and Costa Rica, the prevalence of asthma and associated morbidity is as great or greater as reported in traditional high prevalence countries such as the US, but remains neglected as a public health priority. Asthma in Latin America is associated particularly with underprivileged populations living in cities but remains relatively rare in many rural populations. The causes of asthma in Latin America are likely to be associated with urbanization, migration, and the adoption of a modern ‘Westernized’ lifestyle and environmental changes that follow these processes that include changes in diet, physical activity, hygiene, and exposures to allergens, irritants, and outdoor and indoor pollutants. Because of the enormous social, genetic, and environmental contrasts within and between Latin American countries, and the large differences in prevalence associated with these differences, the investigation of asthma in Latin America provides important research opportunities to identify the social and biological mechanisms that underlie asthma development. Asthma in Latin America poses enormous challenges for health policy makers, health services, and researchers to respond to and alleviate the growing burden of asthma disability, particularly among marginalized urban populations.

“…Nos países desenvolvidos, as taxas de mortalidade aumentaram gradativamente desde 1975, estabilizaram-se entre as décadas de 1980 e 1990 e, a partir daí, começaram a diminuir [2][3][4] . Os dados da América Latina são parcos e, frequentemente, não representam todo o universo de seus habitantes 5 .…”

Objective: To evaluate asthma mortality among Brazilian children up to 19 years old in 1980 to 2007 Methods:This ecological time-series study used the database of the Brazilian Unified Health System, from which data were collected about the number of asthma deaths and the population under 19 years of age in Brazil. Mortality rates were calculated as the number of asthma deaths divided by population and multiplied by 100,000. Linear regression was used to assess the trend of mortality. For the analysis, participants were assigned to three separate age groups: 1-4 years, 5-9 years and 10-19 years.Results: During the study period, there were 9,051 deaths due to asthma in children under 19 years of age. Of these, 69% (6,270 records) of the children were younger than 5 years. There was a significant decrease in asthma mortality during the study in all age groups. The mean annual reduction of asthma mortality rates among children was 0.022 (p < 0.0001). The reduction was 0.076, 0.005 and 0.004 for the 1-to 4-, 5-to 9-and 10-to 19-year-old age groups (p < 0.0001). Conclusion:Asthma mortality among Brazilian children is low and has kept a downward trend during the study in all pediatric age groups.J Pediatr (Rio J). 2012;88(5):384-8: Asthma, mortality, children, retrospective study.

Asthma Mortality in Southern Brazil: Is There a Changing Trend?

Abstract: Asthma mortality in southern Brazil remains low and appears to be decreasing after reaching a peak in the mid-1990s. The reason for these trends remains unknown.
