Quality Assessment of Data on Smoking Behaviour in the WHO MONICA Project
(See Section 3.2, Appendix 2c, Appendix 3a and Appendix 3b.)
| CIGS | "Do you smoke cigarettes now?" 1 = yes, regularly 2 = no 3 = occasionally 9 = insufficient data |
Code 1 if regular smoker. Include subjects who smoke hand-rolled cigarettes regularly.
Code 2 if non-smoker, i.e. the person does not smoke cigarettes at all.
Code 3 is used when the person smokes cigarettes but usually less than one cigarette per
day.
Code 9 for 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 |
Record the average number of cigarettes smoked daily. Include subjects who smoke hand-rolled cigarettes regularly. If CIGS = 1 this item corresponds to Question 2 of the Smoking Questionnaire. If CIGS = 3 this item corresponds to Question 4 of the Smoking Questionnaire. Please make sure that the data for this item are extracted from the relevant question of the Smoking Questionnaire for each subject.
For the amounts 1 - 9, code 001 - 009 and for amounts 10 - 99, code 010 - 099.
Code 888 if CIGS = 2.
Code 999 if data are insufficient to record the daily number of cigarettes.
| DAYCIGS | "On how many days a week do you smoke cigarettes?" 1 = usually on one day a week or less 2 = usually on 2 to 4 days a week 3 = almost every day 8 if CIGS = 1 or 2 9 = insufficient data |
Code 1 if usually on one day a week
Code 2 if usually on 2 to 4 days a week
Code 3 if almost every day
Code 8 if the person does not smoke cigarettes (i.e. if CIGS = 1 or 2)
Code 9 for insufficient data
This question has been added to clarify the pattern of smoking. An ambiguity existed in the old questionnaire whereby a person who smoked a lot on one day could not be differentiated from someone who smoked a little every day.
In an earlier version of the Smoking Questionnaire this question had also the option of "every day", which applied to regular smokers only. If such a Smoking Questionnaire was used, code 8 for the "every day" answers.
| 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 |
Codes 1 and 2 are used for subjects who do not smoke cigarettes regularly now, i.e.
CIGS does not = 1.
Code 1 if answer is "Yes"
Code 2 if the answer is "No"
Code 8 if CIGS = 1
Code 9 if Insufficient Data.
The earlier Smoking Questionnaires had an option for "Occasional past smoking" and this item was not to be asked of "Current occasional smokers". If such a Smoking Questionnaire was used (which was the case in most MCCs for the Second Survey) code 2 for "Occasional past cigarette smokers", and code 9 for "Current occasional smokers".
| STOP | "When did you stop smoking cigarettes regularly?" Record the
year (four digits) 8888 if CIGS = 1 or EVERCIG = 2 9999 = insufficient data |
Record the year using four digits or record 9999 in cases when EVERCIG = 1. If the
subject cannot be sure of the exact year, please give an estimate.
Code 8888 if "Smoking regularly now" or "Never smoked regularly" (i.e.
CIGS = 1 or EVERCIG = 2).
In the earlier Smoking Questionnaires this item was not to be asked of "Current occasional smokers". If such a Smoking Questionnaire was used (which was the case in most MCCs for the Second Survey, code 9999 for "Current occasional smokers."
| IFLYEAR | If in the last 12 months 1 = less than a month ago 2 = between 1 and 6 months ago 3 = between 6 and 12 months ago 8 = not in the last 12 months, or CIGS = 1 or EVERCIG = 2 9 = insufficient data |
Codes 1, 2 and 3 are self-explanatory.
Code 8 if the person smokes regularly now (i.e. CIGS = 1) or has never smoked regularly
(i.e. CIGS = 2), or if the person has stopped smoking cigarettes more than 12 months ago.
Code 9 for insufficient data.
In the earlier Smoking Questionnaires this item was not to be asked of "current occasional smokers". If such a Smoking Questionnaire was used (which was the case in most MCCs during the second survey), code 8 or 9 for "current occasional smokers", depending on whether or not the difference between years DEXAM and STOP is at least two years.
| MAXCIGS | "What is the highest average daily number of cigarettes you have
ever smoked for as long as a year?" Record the number of cigarettes a day. 888 if EVERCIG = 2 999 = insufficient data |
Code the number of cigarettes per day
Code 888 if the subject has never smoked regularly (i.e. EVERCIG = 2)
Code 999 for insufficient data
| CIGAGE | How old were you when you began to smoke cigarettes regularly? 88 if EVERCIG = 2 99 = insufficient data |
Record the age in years when regular smoking first started.
Code 888 if the subject has never smoked regularly (i.e. EVERCIG = 2)
Code 999 if insufficient data.
| CIGARSM | "Have you ever smoked cigars/cigarillos?" 1 = now smoke regularly 2 = no 3 = now smoke oocasionally (less than one/day) 4 = used to, but not now 9 = insufficient data |
Code 1 if regularly now
Code 2 if no
Code 3 if occasionally now
Code 4 if used to, but not now
Code 9 for 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 |
Record the number of cigars or cigarillos smoked.
Code 000 if less than one per week on average
Code 888 if CIGARSM = 2 or 4
Code 999 for 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 |
Code 1 if regularly now
Code 2 if no
Code 3 if occasionally now
Code 4 if used to, but not now
Code 9 for 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 |
Record the number of grams (1 ounce = 30 grams).
Code 000 if less than one gram per week on average
Code 888 if PIPESM = 2 or 4
Code 999 for insufficient data.
| OTHERSM | "For how many hours, on average each day, are you closely subjected
to other people's tobacco smoke?" Record the number of hours. 88 if CIGS = 1 99 = insufficient data |
Record the approximate number of hours. "Closely subjected" in this context
implies that the subject is aware of seeing and smelling, or inhaling the tobacco smoke.
Code 88 if the person smokes regularly now (ie CIGS = 1)
Code 99 for insufficient data
