As health care costs rise and great attention is being paid to the health care system in many countries (perhaps especially the US), the debate is heating up over how to improve public health. Many health problems are greatly increased by the lifestyle choices individuals make – smoking, weight control, and exercise to name a few. The problem is that it is notoriously difficult to change behavior.
There are different ways to approach the challenge of improving lifestyle choices to reduce chronic illness. We can take actions aimed at the individual or aimed at society. These actions can be gentle or passive (the so-called “nudge theory”), or they can be more draconian, such as banning certain activity. We can, of course, do all of these things simultaneously, and may need to in order to have a significant impact.
Affecting Individual Behavior
A common criticism of mainstream physicians is that they do not have much impact on the lifestyle of their patients. This is largely true – although there is no convincing evidence that any practitioners have a significant impact on lifestyle. This is mainly the result of the fact that it is extremely difficult to get people to change their behavior.
