main feature
1, harmfulness
Behavior has direct or indirect, obvious or potential harmful effects on people, themselves and social health. For example, smoking not only harms smokers' own health, but also adversely affects the health of others (causing passive smoking) and social health (affecting the incidence and mortality of smoking-related diseases).
2. Long incubation period
After the behavior is formed, it usually takes a long time to have an impact on health and produce obvious pathogenic effects.
3. Poor specificity
There is no clear correspondence between behavior and disease, indicating that one behavior is related to many diseases and health, and one disease or health is related to many behaviors.
4. Strong synergy
When multiple behaviors exist at the same time, all the factors can cooperate and reinforce each other, and the ultimate harm caused by this synergy will be greater than the sum of the individual actions of each behavior.
5. Large variability
There are obvious individual differences in the size and occurrence time of health hazards caused by behavior.
6. ubiquitous
Behavior widely exists in people's daily life, and there are many people with bad behavior, which is also harmful to health.
7. knowledgeable
Behaviors harmful to health are acquired by individuals through acquired life experience, so they are also called "self-control risk factors".
