- What factors are known to cause increases in blood pressure?
Increases in blood pressure can be caused by stress, eating and exercise habits, and alcohol consumption.
- Use your knowledge about the heart and the circulatory system to make a hypothesis about how the average blood pressure for a group of people would be affected by manipulating the age and gender of the group members.
The majority of the people between the ages of 11-17 have a low or average blood pressure. As they get older, their blood pressure increases significantly. The age range of people 45-54 have a blood pressure that goes beyond then their average. The average blood pressure of women also have significantly lower chances of high blood pressure than males.
- What sorts of problems might a person develop who has chronic hypertension?
A person who has chronic hypertension may have obesity and weight problems and does not exercise as much as they should.
- Analyze the result of your experiment. Explain any patterns you observed.
I noticed that the males generally have a significantly higher blood pressure than the women do. People that are older also have a higher blood pressure than people of the ages 11-17.
- Did the result of your experiment support your hypothesis? Why or why not? Based on your experiment what conclusion can you draw about the relationship of age and gender to group blood pressure averages?
This result did support my hypothesis because i knew the older males would have a higher blood pressure than the younger males and females.
- During the course of your experiment, did you obtain any blood pressure reading that were outside of the normal range for the group being tested? What did you notice on the medical charts for these individuals that might explain their high reading?
I noticed that the people that smoked and do not exercise have a higher blood pressure than those that do. A lot of the patient’s blood pressure was out of range and abnormal compared to the others.
- List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?
Smoking, weight, exercise, diet, daily habits, and stress are risk factors associated with the hypertension. I think stress is the most closely associated with hypertension.
- What effect might obesity have on blood pressure? Does obesity alone cause a person to be at risk for high blood pressure? What other factors, in combination with obesity, might increase a person's risk for high blood pressure?
