Dear Statalist,

I have a question regarding to choosing variables for multiple imputation. For example, I have missing values for smoking, and I'd like to investigate the relationship between smoking and cancer under control of age and sex during regression. There are also some variables that I'd like to adjusted e.g., education and occupation. If I want to obtain a crude OR only ajdusted for age and sex, and an adjusted OR adjusted for education and occupation as well, should I include all variables when imputing smoking for logistic regression on crude OR? Or should I just include age and sex because I will only ajdust for them for a crude OR? Thank you!
