ELSE IF SMOKING=1 AND SMOKENOW=1 THEN SMO_STAT_DAILY=3;

ELSE SMO_STAT_DAILY=.;

Contact round 2:

SMO_STAT_DAILY is based on SENECA variable FSMOKING (“Smoking regularly?”) and FSMOKENO (“Smoking now?”)

IF FSMOKING=2 THEN SMO_STAT_DAILY=1;

MORGAM_SMO_STAT_DAILY

The relevant MORGAM data items are

CIGS: "Do you smoke cigarettes now?"
1 = yes, regularly
2 = no
3 = occasionally
9 = insufficient data

EVERCIG: "Did you ever smoke cigarettes regularly in the past?"
1 = yes, regularly in the past, but not now
2 = no
8 if CIGS = 1
9 = insufficient data

CIGARSM "Have you ever smoked cigars/cigarillos?"
1 = now smoke regularly
2 = no
3 = now smoke occasionally (less than one/day)
4 = used to, but not now
9 = insufficient data

PIPESM "Have you ever smoked a pipe?"
1 = now smoke regularly
2 = no
3 = now smoke occasionally (less than once a day)
4 = used to, but not now
9 = insufficient data

Data on current daily cigar and pipe smoking are not available from all MORGAM cohorts, and their prevalence is always small compared to daily cigarette smoking. Data on former daily cigar or pipe smoking is not available at all. This conversion is based on cigarettes smoking, with the addition that if the person is known to to currently smoke pipe or cigar daily, he is considered as a current daily smoker.

For details, see the MORGAM smoking data assessment.

HAPIEE_SMO_STAT_DAILY

Based on HAPIEE baseline variable l39 for current smoking:

l39 "Do you smoke cigarettes?"

1 "Yes, regularly, at least 1 cigarette a day"
2 "Yes, occasionally, less than 1 cigarette a day"
3 "No, I smoked in the past but I stopped"
4 "No, I have never smoked" 
.   Missing

ESTHER_SMO_STAT_DAILY

Source of smostat are the variables L40ZIG, L41RAU2 and L42ZIGNU from the participant's questionnaire.

EPIC_SMO_STAT_DAILY

The variables SMO_CIGAR, SMO_CIG, SMO_PIPE, SMO_ST were used for the production of SMO_STAT_DAILY according to the following definition and rule.

Var definition(s):
SMO_CIGAR: current cigar smoking status (0=no, 1=yes, 9=missing)

SMO_CIG: current cigarettes or cigarillos smoking status (0=no, 1=yes, 9=missing)

SMO_PIPE: current pipe smoking status (0=no, 1=yes, 9=missing)

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

Coding rule:
Variable SMO_STAT_DAILY shows the current smoking status.

Is equal to 1 if the person is neither smoking cigars (SMO_CIGAR=0) nor cigarettes or cigarillos(SMO_CIG=0) nor pipe (SMO_PIPE=0).

Otherwise if the person was a former smoker (SMO_ST=2) then SMO_STAT_DAILY=2.

Otherwise if the smoking staus is unknown (SMO_ST=4) then SMO_STAT_DAILY=9. 

Otherwise if the person is either smoking cigars (SMO_CIGAR=1) or cigarettes or cigarillos(SMO_CIG=1) or pipes (SMO_PIPE=1) then SMO_STAT_DIALY is equal to 3.

Coding rule in STATA:
-gen SMO_STAT_DAILY = 1 if SMO_CIGAR==0 & SMO_CIG==0 & SMO_PIPE==0

-replace SMO_STAT_DAILY = 2 if SMO_ST==2

-replace SMO_STAT_DAILY = 9 if SMO_ST==4

-replace SMO_STAT_DAILY = 3 if SMO_CIGAR==1 | SMO_CIG==1 | SMO_PIPE==1
