Multi-factorial model is that there are many factors such as biological, psychological and cultural that cause health and illness. Biological factors are things like a person's age, family history, gender and ethnicity. Social-cultural facts such as access to health care, social economic status and family circumstance.

Behaviors such as smoking, diet, drinking alcohol, safety practices and going to the doctor or dentist are other factors.
