An effective programme to prevent a chronic disease should target (select one):

Question

Quizplus · Accepted Answer

A programme will be most effective if it targets the component cause with
the highest PAF as this will prevent the greatest proportion of disease.While this may
also be the component cause with the highest relative risk for disease (D) or the most
common component cause (F), this is not always the case.While targeting the
necessary cause of a disease (A) would lead to complete eradication, chronic diseases
rarely have a necessary cause (cervical cancer is a rare exception) and thus this is not
going to be feasible.It is not necessary to target a sufficient cause (B) because removing
just one component of that sufficient cause would prevent disease.For example
smoking alone cannot cause lung cancer (because not all smokers get lung cancer) but
elimination of smoking would prevent a high proportion of lung cancers from occurring.
