stroke risk

Postby zak » Thu Nov 07, 2013 11:47 am

The two tables below give the relative-risk of developing a stroke, in relation to blood pressure and body mass index. The data are based on a population of men from the USA. The values in the first table are given in comparison with the total population. The values in the second table are given in relation to the lowest BMI category (<23). In both tables the values have been adjusted for the age of the individuals.
_
Blood pressure [mm, Hg] 122/73 125/76 130/77 135/79 140/82 146/84 150/86
Relative risk: Stroke 0.98 1.08 1.23 1.40 1.63 1.88 2.1
BMI [Kgm-2] <23 23-25 25-27 27-30 >30
Relative risk: Stroke 1.0 1.09 1.35 1.57 2.12
Choose the statement(s) below supported by the data given.
Select one or more:
a. Adopting a mediterranean diet will reduce the risk of having a stroke.
b. Reducing blood pressure or BMI reduces the risk of stroke in men. This one correct
c. People with blood pressure of 122/73 are less likely to get a stroke than the general population.

d. Blood pressure increases progessively with a higher BMI.
e. Men who are overweight, have no increased risk of having a stroke, provided they are not obese.

The question asks for statements that are supported by the data. Some statements may be true, but are not supported by the data .First time i select only (b) but they say that i have correctly selected 1 but still Some of my choices are incorrect. this time I select (b) (d)(e) can somebody tell me are they correct plz help me.

a. there is no mention of the diet, so no
b. yes
c. yes
d. If I understood correctly, those are separated tables and there's no relation between those two. So there is no link shown in your datasets
e. I'm not sure which BMI is overweight and which is obese, but unless <23 is overweight, no

Cis or trans? That's what matters.

My try:
- increasing tax to tobacco
- decreasing consumption of saturated fats (this is probably the expected correct answer, but in the last years the harmful effect of saturated fats on the heart health was questioned, just saying
- walking to work
- adopting vegetarian diet
- meditating can decrease stress, which can contribute to heart disease, but a research would be needed to confirm, if meditating people have less heart disease.
- more frequent health checkups might also help...

Healthy people should not try to prevent heart disease by taking drugs, such as aspirin or ACE inhibitors, I think.
French are one of the biggest wine drinkers and have relatively low rate of heart disease - this is known as a French paradox - not solved yet. So, wine as such, in reasonable amounts, is not harmful for heart.
Do people who live in cities with a lot of sport objects have less heart disease? I'm really not sure about this.
