1. State a problem about the relationship of age and gender to blood pressure.
There are many factors that are related to blood pressure. The most prevalent and often the one that can’t be controlled, is heredity.
2. 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.
Blood Pressure (B/P) can be manipulated in males and females just by the genetic that they inherit. A person will also inherit their height and weight to a point which can affect B/P. With ones physical traits they might be more or less prone to exercise, which will affect the efficiency of their circulatory system. Those that don’t exercise tend to have a poor diet and might have increased sodium levels affecting their B/P. Age in both genders will affect the blood pressure also; as the body gets older the vessels lose their elasticity and can’t help regulate B/P. In younger ages the circulator system works more efficient and there is less B/P problems.
3. How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?
The steps that I will use will be orderly, starting with one gender and moving through the age group. As I move through the age groups I will key in on increased B/P, heredity and poor health by lack of exercise and sodium intake.
4. Analyze the result of your experiment. Explain any patterns you observed.
General B/P issues began to start in the older age groups, in both genders. With the increased age the weight and lack of exercise started becoming prevalent. In females I also noticed those same people had increased sodium levels. Heredity played some part in certain people but not as much as I thought it would have.
5. 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?
I don’t think so; I found that heredity took back seat to weight and poor exercise habits. In females the weight played a big part and with males the lack of exercise and poor weight played a part. Both genders had heredity hypertension playing a part. As age increased these factors became more prevalent.
6. 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?
Yes as the age groups got older the B/P’s consistently got out of normal range. Only in a few cases, but it was enough to be noticed. Those people tended to be in poor shape and had increased weight, plus some heredity.
7. List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?
The weight of people and their medical history.
8. 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?
General cardiac out put is affected due the weight that the heart and body have to support. The lack of exercise due to the weight, and poor eating habits which cause the increased weight play a role in hypertension. Other diseases that cause or affect B/P such as diabetes are seen in over weight people, and can cause poor health with risk of high B/P.
