Prevention paradox

In today's world, Prevention paradox has become a topic of great relevance and interest to a large number of people. Since its discovery until today, Prevention paradox has been the subject of multiple studies, debates and scientific advances that have contributed to expanding our knowledge on this topic. In this article, we will explore different aspects related to Prevention paradox, analyzing its impact on society, its evolution over time, and the possible implications it has for the future. Through a multidisciplinary perspective, we will seek to understand in depth everything that Prevention paradox has to offer, and how its influence extends to different areas of our daily lives.

Not to be confused with Preparedness paradox.

The prevention paradox describes the seemingly contradictory situation where the majority of cases of a disease come from a population at low or moderate risk of that disease, and only a minority of cases come from the high risk population (of the same disease). This is because the number of people at high risk is small. The prevention paradox was first formally described in 1981[1] by the epidemiologist Geoffrey Rose.

Especially during the COVID-19 pandemic of 2020, the term "prevention paradox" was also used to describe the apparent paradox of people questioning steps to prevent the spread of the pandemic because the prophesied spread did not occur.[2] This however is instead an example of a self-defeating prophecy[3] or a preparedness paradox.

Hypothetical case study

For example, Rose describes the case of Down syndrome where maternal age is a risk factor. Yet, most cases of Down syndrome will be born to younger, low risk mothers (this is true at least in populations where most women have children at a younger age). This situation is paradoxical because it is common and logical to equate high-risk populations with making up the majority of the burden of disease.

Another example could be seen in terms of reducing overall alcohol problems in a population. Although less serious, most alcohol problems are not found among dependent drinkers. Greater societal gain will be obtained by achieving a small reduction in alcohol misuse within a far larger group of "risky" drinkers with less serious problems than by trying to reduce problems among a smaller number of dependent drinkers.
