Quality Assessment of Data on Smoking Behaviour in the WHO MONICA Project
(See Section 3.2, Appendix 2a, Appendix 3b and Appendix 3c.)
| CIGS | "Do you smoke cigarettes now?" 1 = yes, regularly 2 = no (if no, record 888 in NUMCIGS) 3 = occasionally 9 = insufficient data |
Code 1 if regular smoker, i.e. the person smokes cigarettes every day.
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 not regularly.
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 number of cigarettes smoked daily. If CIGS = 3 and the average number of cigarettes is less than one per day this item should be coded 000.
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.
| EVERCIG | "Did you ever smoke cigarettes in the past?" 1 = yes, regularly in the past, but not now 2 = no, never 3 = yes, occasionally in the past, but not now 8 = yes, and still regularly or occasionally now 9 = insufficient data |
Codes 1 and 3 are used for persons who have stopped smoking. In such cases CIGS =
2 or 9 and NUMCIGS = 888 or 999.
Code 2 is used for never-smokers. In such cases CIGS = 2 and NUMCIGS = 888
Code 8 if CIGS = 1 or 3
| STOP | "When did you stop smoking cigarettes?" Record the year (four
digits) 8888 = smoking regularly or occasionally now, or never smoked 9999 = insufficient data |
Record the year with four digits or record 9999 in cases when EVERCIG = 1 or 3.
Code 8888 if smoking now or never smoked, i.e. EVERCIG = 2 or 8.
| 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 smoking regularly or occasionally now, or never smoked 9 = insufficient data |
Codes 1, 2 and 3 are self-explanatory.
Code 8 is used if the person is a smoker, i.e. CIGS = 1 or if the person smokes only
occasionally, i.e. CIGS = 3 or if the person has never smoked, i.e. EVERCIG = 2, or if the
person has stopped smoking more than 12 months ago.
Code 9 for insufficient data.
| CIGAR | "About how many cigars/cigarillos do you smoke per week?"
Record the number. 999 = insufficient data |
Record the number of cigars or cigarillos smoked.
Code 000 if a non-smoker or occasional smoker (less than one per week on average).
Code 999 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) 999 = insufficient data |
Record the number of grams (1 ounce = 30 grams).
If a non-smoker or occasionally smoker (less than one gram per week on average), code 000.
Code 999 for insufficient data.
