Insights
Hypertension significantly increases mortality risk, particularly for cerebrovascular and ischemic heart diseases. This study highlights the importance of considering all causes of death, not just underlying ones, for accurate mortality assessments.
Area of Science:
- Epidemiology
- Cardiovascular Research
- Public Health
Context:
- Accurate mortality studies are crucial for public health.
- Previous analyses often focused solely on the underlying cause of death.
- Understanding the role of hypertension in mortality requires a comprehensive approach.
Purpose:
- To validate mortality studies by examining hypertension's role at the time of death.
- To assess the relationship between hypertension and cardiovascular/cerebrovascular diseases using a multiple-cause-of-death analysis.
- To compare mortality data based on underlying cause versus all listed causes.
Summary:
- This proportional mortality study analyzed deaths in April-May 1985, considering all listed causes on death certificates.
- Hypertension was found to be associated with a higher number of deaths when multiple causes were considered compared to only the underlying cause.
- The adjusted odds ratio for hypertension and ischemic heart disease was 4.1, and for cerebrovascular disease, it was 21.1.
Impact:
- This research underscores the critical impact of hypertension on mortality, especially for cardiovascular and cerebrovascular conditions.
- The findings emphasize the necessity of incorporating multiple causes of death into mortality studies for greater accuracy.
- This approach provides a more robust understanding of disease burden and hypertension's contribution to mortality rates.
Abstract:
In order to validate mortality studies, we described the role of hypertension at the time of death of people who died during April and May 1985. This analysis take into account all the causes listed in death certificates and not only the underlying cause. A proportional mortality design was used to evaluate the relationship of hypertension, cerebrovascular and cardiovascular disease. The number of deaths associated to hypertension was larger by multiple cause than by underlying cause. The odds ratio for hypertension and ischemic heart disease was 4.1 adjusted by age and sex, and 21.1 for cerebrovascular disease.
