State a problem about the relationship of age and gender to blood pressure.
Generally, blood pressure rises as age increases. Lifestyle choices such as smoking, drinking, and lack of exercise result in increased blood pressure. As people age their behaviors often include these lifestyle choices, and it is prolonged exposure to to unhealthy habits that affect blood pressure. Males tend to develop high blood pressure earlier in life than women. There is an interesting article here regarding research between the incidences of high blood pressure between the two genders:

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 average blood pressure of the group would increase, as the age group increases in years, and vice versa. (The average blood pressure of the group would decrease, as the age group decreases in years). Also, the male subjects will have earlier onset high blood pressure.
How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?
I will focus on the individuals with obvious hypertension. I will review their medical history in comparison with those that show similar results, and also with those that show no obvious hypertension. I will record the similarities in the lifestyle choices and demographics for each individual experiencing hypertension.
Analyze the result of your experiment. Explain any patterns you observed.
The experiment showed that age and body weight contribute greatly to the blood pressure of an individual. Persons that were obese and in an older age demographic had greater instances of hypertension. Hypertension occurred earlier in males than in females. Hypertension seemed to be greater influenced by behavior/lifestyle choices than family history.

This table shows the average blood pressure for males and females participating in the study for various age demographics.
This graph presents the information from the table above. 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, the results of the experiment supported my hypothesis. The average blood pressure of the group increased as the average age of the group increased. Also, hypertension was earlier onset in the male gender. I was surprised that there were an equal number of men and women (six out of 50) in each group that showed hypertension. From this experiment, hypertension is equally prevalent in 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?
There were twelve total high blood pressure readings that were outside the normal range for the test groups. Most of these individuals had a combination of the following in common: a past family history of hypertension, a high salt diet, alcoholic consumption, and lack of exercise. Obesity alone resulted in hypertension in several cases.
List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?
Some risk factors associated with hypertension are age, race, gender, heredity, obesity, alcoholic consumption, diabetes, and inactive lifestyle. From this particular study, obesity is 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?
Obesity changes the structure and function of the heart. (http://www.fairview.org/healthlibrary/content/ca_fatheart_car.htm) Obese people often have high blood pressure because their heart is working harder. Obesity alone does cause a person to be at risk for high blood pressure. There are however, other factors that increase a person’s risk for high blood pressure. These are listed in the previous question. Also, studies have shown that females taking oral contraceptives are at risk for high blood pressure.

Nicotine also narrows the vessels that carry the blood, making your already weakened heart pump against increased pressure. Smoking is a risk factor for high blood pressure, heart failure, and coronary artery disease, which lead to heart attack. Smoking harms the heart extensively. The best action you can take to chantix is to stop smoking. http://www.chantixhome.com/
