SHARE_SMO_NUMTOBAC
SMO_NUMTOBAC is based on SHARE variables br007 and br008
BR007_ AVERAGE AMOUNT OF PIPES PER DAY
How many pipes [do/did] [you/you] [smoke/smoke] on average per day?
___________ (0..120)
BR008_ AVERAGE AMOUNT OF CIGARS PER DAY
How many cigars or cigarillos [do/did] [you/you] [smoke/smoke] on average per day?
___________ (0..120)
Asked only in wave 1 and 2.
MORGAM_SMO_NUMTOBAC
SMO_NUMTOBAC is derived from MORGAM variables CIGS, NUMCIGS, PIPE, CIGAR, PIPESM and CIGARSM:
CIGS
"Do you smoke cigarettes now?"
1 = yes, regularly
2 = no
3 = occasionally
9 = insufficient data
NUMCIGS
"On average how many cigarettes do you now smoke a day?" Record the number of cigarettes a day.
888 if CIGS =2
999 = 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
CIGAR
"About how many cigars/cigarillos do you smoke per week?" Record the number.
888 if CIGARSM = 2 or 4
999 = 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
PIPE
"About how many grams of pipe tobacco do you smoke per week?" Record the number of grams. (1 ounce = 30 grams)
888 if PIPESM = 2 or 4
999 = insufficient data
We define first intermediate variables TOBAC1, TOBAC2 and TOBAC3:
("n" denotes any value which is at least 0 but less than 888 (i.e. 0≤n<888))
TOBAC1:
| NUMCIGS |
CIGS=1 |
CIGS=2
|
CIGS=3
|
CIGS=9
|
| n |
TOBAC1 = n
|
TOBAC1 = 0
|
TOBAC1 = n
|
TOBAC1 = n
|
| 888 |
TOBAC1 = 9999 |
TOBAC1 = 0 |
TOBAC1 = 0
|
TOBAC1 = 9999
|
| 999 |
TOBAC1 = 9999 |
TOBAC1 = 0 |
TOBAC1 = 0
|
TOBAC1 = 9999
|
TOBAC2:
| PIPE |
PIPESM=1 |
PIPESM=2
|
PIPESM=3
|
PIPESM=3 |
PIPESM=9
|
| n |
TOBAC2 = n/7
|
TOBAC2 = 0
|
TOBAC2 = n/7
|
TOBAC2 = 0 |
TOBAC2 = n/7

TOBAC2 = 0 |
TOBAC2 = 0

|
| 999 |
TOBAC2 = 9999 |
TOBAC2 = 0 |
TOBAC2 = 0
|
TOBAC2 = 0 |
TOBAC2 = 0
|
TOBAC3:
| CIGAR |
CIGARSM=1 |
CIGARSMS=2
|
CIGARSM=3
|
CIGARSM=3 |
CIGARSM=9
|
| n |
TOBAC3 = 3n/7
|
TOBAC3 = 0
|
TOBAC3 = 3n/7
|
TOBAC3 = 0 |
TOBAC3 =3 n/7
|
| 888 |
TOBAC3 = 9999 |
TOBAC3 = 0 |
TOBAC3 = 0
|
TOBAC3 = 0 |
TOBAC3 = 0
|
| 999 |
TOBAC3 = 9999 |
TOBAC3 = 0 |
TOBAC3 = 0
|
TOBAC3 = 0 |
TOBAC3 = 0

If none of TOBAC1, TOBAC2 or TOBAC3 is missing, then SMO_NUMTOBAC=TOBAC1+TOBAC2+TOBAC3. Otherwise, SMO_NUMTOBAC=9999(missing).
EPIC_SMO_NUMTOBAC
The variables n_cigars, n_pipe, n_cigarettes, SMOKE_STAT_DAILY were used for the production of SMO_NUMTOBAC according to the following definition and rule.
var definition(s):
n_cigars: EPIC elderly Greece variable showing number of cigars smoked per day (is equal to N_CIGARS/7)
n_pipe: EPIC elderly Greece variable showing number of pipes smoked per day (is equal to N_PIPE/7)
n_cigarettes: EPIC elderly Greece variable showing number of cigarettes smoked per day (is equal to N_CIGRET/7)
SMOKE_STAT_DAILY: current daily smoking status (1=never daily smoker , 2=former daily smoker, 3=daily smoker, 9=unknown)
Coding rule:
Variable SMO_NUMTOBAC shows amount (in grams) of currently smoked tobacco per day. Is produced from the formula (5*number of cigars per day) + number of cigarettes per day + (5*number of pipes per day) **
If the person has been a former (SMOKE_STAT_DAILY=2) or a never daily smoker (SMOKE_STAT_DAILY=1) then SMO_NUMTOBAC is equal to 0.
Otherwise SMO_NUMTOBAC is coded as missing (9999).
Coding rule in STATA:
-gen SMO_NUMTOBAC = (5*n_cigars) + n_cigarettes + (5*n_pipe)
-replace SMO_NUMTOBAC = 0 if SMOKE_STAT_DAILY==1 | SMOKE_STAT_DAILY==2
-recode SMO_NUMTOBAC = 9999 if SMO_STAT_DAILY==9
**1 cigar equals 5 grams of tobacco, 1 cigarette equals 1, 1 pipe equals 5 grams.
