What data should be collected to evaluate health risk factor y

Relative risk factors and absolute risk factors Relative risk factors are the probability that an individual may develop coronary heart disease with or without some known risk factors or at a certain risk factor intensity. Absolute risk factors are indicators of the possibility of coronary heart disease in a certain period of time, such as 10 years. In a sense, relative risk factors reflect the probability that patients naturally turn into absolute risk factors. The data of blood cholesterol research well illustrates the difference between relative and absolute risk factors: compared with a person with low blood cholesterol level, adults with high cholesterol level have lower absolute risk factors for coronary heart disease, but higher relative risk factors. Adults with hypercholesterolemia are unlikely to develop coronary heart disease in the near 10 years, but in the long run, they are prone to early coronary heart disease before the age of 65. Framingham's long-term follow-up data also confirmed this view, that is, the blood cholesterol level of young and middle-aged people is inversely proportional to life expectancy. Other research results also support the view that high relative risk factors will also turn into high absolute risk factors in young and middle-aged people over time. Recently, there is a wrong view among some researchers that after atherosclerosis, using a large number of cholesterol-lowering drugs can completely prevent the absolute risk factors of coronary heart disease. It is true that lowering cholesterol in patients with severe atherosclerosis can greatly reduce the incidence and mortality of coronary heart disease. However, among these patients who are receiving cholesterol-lowering treatment, the high incidence of coronary artery malignant events is still difficult to completely avoid.
