Answer:

The correct option is E: There is either no association or a negative association between the factor and the disease

Explanation:

Relative risk is a ratio that compares the risk of a health event between two groups. When the relative risk is 1, this means that the risk among the two groups are identical. When the relative risk is more than one, this means there is an increased risk for the exposed group. A risk ratio of less than 1, means that there is decreased exposure, which means negative association, which implies that exposure protect against the disease. Hence from the question, a value of relative risk less than or equal to one signifies no association or negative association.

Smoking can put smokers at risk for health problems but smokers are also subject to social consequences write a short letter to
vladimir2022 [97]


Dear (random name),
I have heard that you were smoking. In health class, I was taught why smoking cigarettes is very bad for you. It is harmful for you because it effects you socially and physically. Please read this, because I care about your health.

First of all, smoking is bad for your social life. When you smoke, you stench of cigarettes, and nobody likes the smell of ashes. You will most likely be surrounded by the bad people who peer pressured you into smoking, and they may lead you to doing even worse habits. Also, second hand smoke also hurts people’s lungs, and nobody wants to be around someone that might give them lung cancer. You won’t have lots of friends, and you’ll be around the wrong people.

Second of all, smoking is bad for you physically. You might get all sorts of diseases and cancers. Lung cancer, brain damage, and heart disease are just some of them. It will affect your body, so if you were trying to have children, your child would be seriously impacted by your bad habit. Also, if you smoke too much, you will age faster, getting yellow teeth and wrinkles. That is harmful to your body.

From the reasons I have listed, this shows why you should stop smoking. It takes a heavy toll on your social and physical health. If you get help now, you can kick the habit before it takes over your whole life. Be smart and make the right decision.

Sincerely,
(Your name)
