MORGAM_SMO_CIGAR

The variable is similar to the MORGAM variable CIGARSM:

In some MORGAM Centres, the local question(s) from which the MORGAM data was extracted deviated from the MORGAM question. E.g. in some cohorts, pipe and cigar smoking was included in the question or regular and occasional smokers cannot be separated. For details of the deviations, see the MORGAM smoking data assessment .

EPIC_SMO_CIGAR

The variables CIGARS, N_CIGARS, SMOKE_ST were used for the production of SMO_CIGAR according to the following definition and rule.

EPIC var definition(s):
CIGARS: Epic elderly variable showing currently smoked cigars (0=no, 1=yes)

N_CIGARS: Epic elderly variable showing number of cigars per week

SMOKE_ST: Epic elderly variable showing smoking status (1=never, 2=former, 3=smoker, 4=unknown)

Coding rule:
Variable SMO_CIGAR shows whether the person is smoking cigars. Is equal to 0 if the person does not smoke cigars currently or the info is unavailable (CIGARS=. or 0)

Is equal to 1 if the person is smoking cigars currently (CIGARS=1) or the number of cigars per week is greater than 1 (N_CIGARS>=0 & N_CIGARS~=.).

Otherwise SMO_CIGAR is coded as missing if smoking status is unavailable (SMOKE_ST=4) or the person is a daily smoker (SMO_STAT_DAILY=3) and the person is neither smoking cigar (SMO_CIGAR=0) nor cigarettes (SMO_CIGS=0) nor pipe (SMO_PIPE=0)

Coding rule in STATA:
-gen SMO_CIGAR = 0 if CIGARS==.

-replace SMO_CIGAR = 0 if CIGARS==0

-replace SMO_CIGAR = 1 if CIGARS==1

-replace SMO_CIGAR = 1 if N_CIGARS>=0 & N_CIGARS~=.

-replace SMO_CIGAR = 9 if SMOKE_ST==4

-replace SMO_CIGAR=  9 if SMO_CIGAR==0 & SMO_CIGS==0 & SMO_PIPE==0 & SMO_STAT_DAILY==3
