You have a secretive friend, and, among other questions, you are interested in knowing whether he is a millionaire. You are aware that there are some attributes, or risk factors, that are thought to be linked to being a millionaire. You decide to investigate. The first step is to choose your definition of risk factor. Clinical research can generally be divided into four broad objectives based on the intended use of the information obtained by the study: diagnosis, prognosis, treatment effects, and aetiology. Each of these research objectives is associated with a different definition. Table 1⇓ gives examples of how these four definitions of risk factor are used in the scientific literature and shows how each definition describes a different relation between the dependent variable and the independent variable. View this table: Table 1 Objectives of clinical research and associated definitions of risk factor A variable may qualify as a risk factor under more than one definition of the term. For example, cholesterol is believed to be a risk factor for heart disease under each of the four definitions. However, it is generally not plausible to assume that a variable that is a risk factor according to one definition will always be a risk factor under the …

American Stroke Month
Strokes can happen to anyone, at any age. Having a stroke puts you at higher risk for a second one. Learn the f.a.s.t. warning signs of stroke and know your risk factors. Together, we can be a bold advocate for ourselves and others.

I'm an expert on strokes, having suffered my own hemorrhagic stroke 5 years ago.I recognized the signs immediately and got help quickly. I'm lucky to be alive, but was left with some disabilities. Learn the warning signs to save another...or yourself.

I was in good shape, walked 3 miles a day, and hiked almost weekly, plus worked out 5 times a week. I was slender, and ate well. I was never sick. The one thing I didn't do? Monitor my blood pressure. It sneaks up on you, and you don't feel it. I did have occasional migraines, but I don't have them now.
