Cardiovascular mortality trends in Harris County, Texas: 1980 to 1986
Insights
Cardiovascular disease mortality rates declined in Harris County, Texas, between 1980-1986. Declines were seen across most ethnic groups, though Black populations consistently had higher mortality rates.
Area of Science:
- Public Health
- Epidemiology
- Cardiovascular Science
Background:
- Cardiovascular diseases (CVD) are a primary cause of death nationwide and in Texas.
- Understanding temporal trends and demographic disparities in CVD mortality is crucial for public health interventions.
Purpose of the Study:
- To analyze trends in cardiovascular disease mortality rates in Harris County, Texas, from 1980 to 1986.
- To examine these trends within specific geographic regions (entire county vs. excluding Houston) and across different ethnic populations.
Main Methods:
- Retrospective analysis of cardiovascular disease mortality data for Harris County, 1980-1986.
- Stratification of data by geographic area, ethnicity (white, black, Hispanic, other), and sex.
- Comparison of mortality rates over the 7-year study period.
Main Results:
- Overall cardiovascular disease mortality rates decreased in Harris County during the study period.
- Significant declines were observed in white and Hispanic populations for heart disease and cerebrovascular diseases.
- Black populations consistently exhibited higher cardiovascular mortality rates compared to other ethnic groups, with an increase noted in males within the "other" ethnic category.
Conclusions:
- Cardiovascular disease mortality shows a downward trend in Harris County, mirroring national patterns.
- Ethnic and sex-based disparities in cardiovascular disease mortality persist, particularly higher rates among the Black population.
- Data on temporal changes and demographic variations in cardiovascular disease mortality are vital for targeted public health planning and disease prevention strategies.
Abstract:
Cardiovascular diseases are the leading causes of death in Texas and in the United States. This study determines the trend in mortality rates attributed to cardiovascular diseases in Harris County from 1980 to 1986. The region of the county that does not include the City of Houston was specifically studied. Mortality of cardiovascular diseases in these two areas follow patterns similar to that of the United States in the same time period. Both the entire county and Harris County excluding Houston show declines in cardiovascular mortality rates in the 7-year period. The populations were divided into four ethnic categories (white, black, Hispanic and "other"), and each ethnic group reported significant declines in overall cardiovascular mortality except in the "other" population, which showed an increase in the male group. Significant downward trends were noticed in the white and Hispanic population in the two major subcategories of cardiovascular diseases: diseases of the heart and cerebrovascular diseases. The black population in each geographic area studied was consistently higher in cardiovascular mortality than the other three ethnic groups observed (white, Hispanic and "other"). Knowledge of cardiovascular disease mortality rates by ethnicity, sex, and age as well as temporal changes in mortality rates within Harris County are important for health planners in continuing and implementing programs aimed at awareness, prevention, and treatment of cardiovascular diseases.
