Factors related to patient smoking status.

Abstract
To investigate those factors associated with patients' cigarette smoking status, 455 consecutive patients seen in two specialty clinics and one general medicine clinic at a university medical center were studied. Patient's age, sex, health status, and number of previous cessation attempts discriminated current from ex-smokers. A strong interaction was observed between sex and disease status with females showing a greater impact of smoking-related disease on smoking behavior than males.
