Journal Questions
1) State a problem about the relationship of age and gender to blood pressure?
I think that men will have a higher blood pressure reading then wemon up until they get into there 45's then i think i'll see more blood pressures that are higher.

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?
From my knowledge i beleive that men will have more hypertension than women. As for the age I think its safe to say that up until there 50's men will have higher blood pressure and well find more cases of hypertention compared to women.

3) How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?
To start I am going to test all the women and look at all the medical history charts that might show that their blood pressure is high. The n i will do the same to the men. After I plan to compare and see the main cause for the hypertension.

4) Analyze the result of your experiment. Explain any patterns you observed?
As the ages increased for the men the more hypertensions there were. As for the women there wasnt really too many cases until they got into there mid 40's. In almost every testing besides the 11-17 group there were up to 5 cases of hypertension. Most of the charts also stated that there was a lack of excersise, lots of salt or alcohol present so I wonder if thats a big factor of hypertension.

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?
Yes, my experiment supported my hypothesis pretty close i would say. I stated that as you get older the blood pressure would and in my experiment that is just what happened. Women always had a lower blood pressure average and men always had more hypertension cases. As for gender the only thing that i can see is that the men weighted more then women so its a possibility that, that is why men have higher blood pressures.

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, infact i have a total of 14 abnormal readings. There were 4 case of family history, 11 cases of overweight, 7 cases of high-salt diet, 7 cases of lack of excersise, and 4 cases of alcohol consumption.

7) List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?
There were five factors that could have been checked and I think for the most part they all have something to d owith hypertension. Overweight, lack of excersise, high-salt diet, family history of hypertension, and alcohol consumption are the factors and i think they all have a role but my experiment showed that alcohol consumption was not as proitent as the others.

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?
Obesity was very high in the charts of those who hda hypertension. In the 11 cases I had theres something else stating that there is a lack of exercise or high-salt diet. Obese people i think have a higher risk of having a case of hypertension but I think that really if thats combined with any of the other factors it would greatly increase there chances.
