According to the New York State Department of Health, risk factors that can be controlled to prevent serious illnesses such as high-blood pressure, obesity and cardiovascular disease include tobacco use, physical inactivity and poor diet. Many of these risk factors are related each other. For example, smoking can lead to high blood pleasure, which can be a factor in the development of cardiovascular disease.
According to the Centers for Disease Control and Prevention, more than 80 percent of lung cancers can be attributed to cigarette smoking and exposure to second-hand smoke. Since 1964, the rates of men smoking or first starting to smoke have decreased more significantly than the same rates for women, and lung cancer incidence has decreased more rapidly among men than women. This suggests a significant correlation between control of the risk factor and prevention of the disease.
The results of studies about controlling the risk factor of physical inactivity are just as compelling. A mere 2 hours and 30 minutes of moderate aerobic exercise a week has been shown to reduce the risk for stroke and cardiovascular disease. And the risks are reduced even more with increases in such exercises. Individuals who are physically active at these moderate levels also have lower incidences of colon and breast cancers than physically inactive individuals, according to the CDC.
