Document Summary

Macro/high-risk & macro/population based approaches to hp or disease prevention. Individuals deemed at high risk to develop a certain disease are targeted to receive the health intervention: screening for gum cancer in an individual who chews smokeless to. People fro(cid:373) a(cid:373)sterda(cid:373) come for a period of time and then leave sober. Limited potentials cont: large numbers of people at minimal risk for a disease can actually produce higher incidence rates than small numbers of people at highest risk for the disease, e. g. 5 million people with 20% risk = 1 million people who will get the disease. Vs: 10000 people with 60% risk = 6000 people will get the disease. Limitations of the population-based approach: on a population-scale, benefits are outstanding, but on an individual basis, benefit are minimal, lack of motivation for population & practitioners (e. g. , bmi of 28 vs acute mi patient re exercise)
