Insights
Mortality from cardiovascular diseases and stroke declined in Brazil. However, the downward trend in ischemic heart disease mortality halted between 2007 and 2012.
Area of Science:
- Public Health
- Epidemiology
- Cardiovascular Research
Background:
- Recent trends in cardiovascular disease (CVD) mortality in Brazil have been questioned.
- Understanding these trends is crucial for public health strategies.
Purpose of the Study:
- To analyze recent mortality trends for ischemic heart disease (IHD) and stroke in Brazil.
- To assess changes in CVD, IHD, and stroke mortality in men and women.
Main Methods:
- Utilized mortality and population data from Brazilian official sources.
- Applied direct method for age adjustment using the 2000 world population as reference.
- Analyzed trends for 1980-2006 and 2007-2012 periods.
Main Results:
- Cardiovascular disease and stroke mortality decreased significantly in both sexes across both periods.
- Annual mortality variations showed a consistent decline for CVD and stroke.
- Ischemic heart disease mortality decreased from 1980-2006, but showed no significant change from 2007-2012.
Conclusions:
- While overall CVD and stroke mortality continues to decline, the trend for ischemic heart disease has plateaued.
- This suggests a need for re-evaluation of strategies targeting ischemic heart disease in Brazil.
Background:
Studies have questioned the downward trend in mortality from cardiovascular diseases (CVD) in Brazil in recent years.
Objective:
to analyze recent trends in mortality from ischemic heart disease (IHD) and stroke in the Brazilian population.
Methods:
Mortality and population data were obtained from the Brazilian Institute of Geography and Statistics and the Ministry of Health. Risk of death was adjusted by the direct method, using as reference the world population of 2000. We analyzed trends in mortality from CVD, IHD and stroke in women and men in the periods of 1980-2006 and 2007-2012.
Results:
there was a decrease in CVD mortality and stroke in women and men for both periods (p < 0.001). Annual mortality variations for periods 1980-2006 and 2007-2012 were, respectively: CVD (total): -1.5% and -0.8%; CVD men: -1.4% and -0.6%; CVD women: -1.7% and -1.0%; DIC (men): -1.1% and 0.1%; stroke (men): -1.7% and -1.4%; DIC (women): -1.5% and 0.4%; stroke (women): -2.0% and -1.9%. From 1980 to 2006, there was a decrease in IHD mortality in men and women (p < 0.001), but from 2007 to 2012, changes in IHD mortality were not significant in men [y = 151 + 0.04 (R2 = 0.02; p = 0.779)] and women [y = 88-0.54 (R2 = 0.24; p = 0.320).
Conclusion:
Trend in mortality from IHD stopped falling in Brazil from 2007 to 2012.
