Final answer:
There is a negative correlation between income and blood pressure, meaning as income increases, blood pressure tends to decrease. This could be due to the impact of reduced stress from various stressors on cardiovascular health.
Step-by-step explanation:
When there is a negative correlation between two variables, it indicates that as one variable increases, the other tends to decrease. In the context of the study it highlights that as a person's income increases, their blood pressure tends to decrease. This could be linked to several psychological and physiological factors, such as reduced exposure to stressors that are known to affect cardiovascular health, like job strain, marital conflict, or high traffic noise levels. Managing blood pressure is crucial for avoiding health risks such as stroke and heart attack. Lifestyle changes, such as exercise, dietary adjustments to reduce sodium intake, maintaining a healthy weight, and avoiding excessive alcohol consumption, are important for controlling blood pressure.
