BLOOD PRESSURE LAB

Blood Pressure -
State a problem about the relationship of age and gender to blood pressure.
Depending on the age group and gender highly affects your chances of having hypertension. Obesity and family history are also related.
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.
Unhealthy diets would affect this because older age groups have had a lifetime to eat bad, maybe drink alcohol and/or smoke. High salt diets and lack of excercise. Chances also increase if there is family history.
How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record?
The screen will test 10 individuals at a time in different age and gender groups. Take everybody's BP, add up all diastolic and systolic separately and then average the numbers for that group. Also, take family and medical history from every individual.
Analyze the result of your experiment. Explain any patterns you observed.
Most individuals with high blood pressure had obesity, and family history and poor lifestyle. Younger individuals, however, showed no signs of hypertension. Maybe because they are young, more active, and have not had lifetime to make unhealthy food choices.
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, it showed that obesity and family history have huge impact. Other factors are poor diet and lack of excercise.
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, overweight, poor diet, lack of excercise, family history.
List risk factors associated with the hypertension. Based on your observation, which risk factor do you think is most closely associated with hypertension?
Obesity and family history. Other factors include poor diet, lack of activity, gender and age.
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 would seem to make the heart work harder to pump more blood. Yes obesity alone can be a risk for an indiviual to have high blood pressure but does not guarantee them to get high blood pressure. Other factors that increase a person's risk would be family history, high salt diet, age, and gender.
In the graph it shows the comparison between systolic and diastolic and what the average is in different age groups.
In this picture the table has the average numbers of systolic and diastolic broken up by age groups and gender.
This picture of the table is the same as above except its the end part. Couldn't get all of it in one screen.
